FIELD OF THE INVENTION
[0001] The present invention relates to a hydroponic cultivation system. TECHNICAL STATUS
[0002] Vegetables have long been grown outdoors. However, external cultivation is susceptible to climatic effects, such as lack of water due to extreme weather conditions. For this reason, on-site cultivation, which allows for more planned and more stable vegetable cultivation, has been generating interest in recent years. For example, Patent Literature 1 describes a technique for growing vegetables with a hydroponic growing system. Documents from Previous Patent Literature
[0003] Patent Literature 1: Japanese Patent Publication No. 9-37664 SUMMARY OF THE INVENTION PROBLEM TO BE SOLVED
[0004] A culture solution container would be relatively heavy in the hydroponic culture system described in Patent Literature 1, because a large amount of culture solution is required. For this reason, the strength required for the supporting structure of the container would be high. In addition, the pump for circulating a large amount of culture solution would require high performance. Therefore, the hydroponic cultivation system would require equipment such as a high-performance structure and pump, ample space and, as a result, a considerable cost for the equipment.
[0005] The present invention was conceived in view of such a circumstance. The purpose of the present invention is to provide a hydroponic culture system that can reduce the amount of culture solution. Another objective of the present invention is to provide a system capable of efficient hydroponic cultivation in a space smaller than that of conventional hydroponic cultivation systems. MEANS TO SOLVE THE PROBLEM
[0006] In order to the problem described above, a hydroponic cultivation system according to a configuration, the present invention provides a hydroponic cultivation system comprising: a plurality of containers extending in a predetermined direction; and a plant retaining plate that holds the plant and is arranged to cover the plurality of containers on it, where each of the containers of the plurality of containers is configured to contain a culture solution necessary for cultivating the plant.
[0007] The hydroponic cultivation system according to a certain configuration comprises a first container, a second container, a support mechanism provided between the first and the second containers, and a plant retention plate, which is arranged so to cover the first and the second container on it and is supported by a support mechanism that is capable of moving in a predetermined direction.
[0008] In the hydroponic cultivation system of the present invention, a plurality of containers are arranged that extend in a predetermined direction and the plants are arranged in positions that correspond to the containers on the plant retaining plate above them. Therefore, a plurality of containers would be arranged below the plant retaining plate in the present invention. Below the plant retaining plate are the containers and a space between two adjacent containers. The plant retaining plate holds plants only where there is a container underneath it. As a result, the culture solution is present just below the region where there are plants on the plant retention plate.
[0009] Meanwhile, one or more plant retention plates were submerged in a large container in conventional cultivation systems. Such conventional hydroponic cultivation systems have a large container filled with culture solution inside it, under the entire plant retention plate, regardless of whether the site contains plants. As a result, the culture solution was present under a region on the plate where there was no plant.
[0010] Therefore, the hydroponic cultivation system of the present invention is capable of significantly reducing the amount of culture solution necessary for plant growth, as it has a configuration in which the container and the culture solution are present just below the region that holds the plant in a plant holding plate. This is extremely advantageous when the hydroponic cultivation system is used, for example, in a region that is experiencing water scarcity. In addition, since the container in the hydroponic cultivation system of the present invention has a smaller capacity than conventional hydroponic cultivation systems, the culture solution can be circulated quickly, so that a new culture solution can be successively provided to the plants. As a result, plant growth is promoted and disease is avoided. In addition, as the total quantity of the culture solution is reduced, the necessary level of robustness of the structure that supports the solution, as well as the performance of the pump or similar associated with the circulation of the culture solution, is reduced, generating a reduction in cost.
[0011] For the present invention, a holding mechanism for a plant holding plate, transport mechanism, pipes or the like, can be arranged in the space between the containers under a region on the holding plate where there is no plant. As the entire region below the plant retaining plate in a conventional system was occupied by a container, the space below the region where there is no plant in the plant retaining plate is effectively used in the present invention, in which space reduction is achieved for the entire hydroponic cultivation system. In addition, there is no longer a need for strength of the plant retaining plate by the provision of a holding mechanism for the plant retaining plate, so that the plant retaining plate can be of a lightweight and low-cost material ( eg expanded polystyrene foam). As a light cultivation system comprising a container and a plant holding plate is thus realized, the system can be arranged above or below in multiple rows with a simple mechanism. Also, the light from an irradiation source passes through the space between the containers, in such a way that the light can be efficiently irradiated to the vegetables, maintained by a plant retaining plate in several directions. As a result, the level of growth of cultivated plants can be increased in order to improve productivity.
[0012] In addition, a space is created between the plant retaining plate and the culture solution in a container having a configuration in which the plant retaining plate extends over a plurality of containers or pots. For this reason, the plant root maintained by the plant retention plate is in contact not only with the culture solution, but also with air. Plant growth is promoted by providing air to the environment in this way. This could not be achieved in a conventional hydroponic cultivation system that allows the plant retention plate to be immersed in a large container containing culture solution.

[0017] The present invention is described below with examples and references to the attached drawings, as needed. Throughout the report, a single expression should be understood as encompassing its concept in a plural form, unless otherwise specified. In addition, the terms used herein are to be understood as being used in the sense most commonly used in the matter, unless otherwise specified. Therefore, unless otherwise defined, all the terminologies and scientific technical terms that are used herein have the same meanings as those commonly understood by those skilled in the matter to which the present invention belongs. In case of contradiction, this report (including definitions) takes precedence.
[0018] The configurations reported below are provided for a better understanding of the present invention. Therefore, the scope of the present invention is not limited to the following descriptions. It is apparent to those skilled in the art that the configurations can be appropriately modified without departing from the scope of the present invention.
[0019] (First Configuration) Figures 1-4 show a Hydroponic cultivation system 100 according to the first configuration. Figure 1 is a top view of the hydroponic cultivation system 100. Figure 2 is a cross-sectional view of the BB line in Figure 1. Figure 3 is a cross-sectional view along line AA in Figure 1. Figure 4 is a cross-sectional view along the CC line of Figure 1. As Figure 1 shows the configuration within the hydroponic cultivation system 100, the display of an upper plate 11, artificial medium 4 and plant 2 is omitted.
[0020] The hydroponic cultivation system 100 produces 2 plants, such as vegetables / flowers or flowers, by hydroponic cultivation. Plants 2 can be any vegetable that grows on a plant retention plate 30 and is suitable for hydroponic cultivation, but is preferably an agricultural product. Examples of agricultural products destined for the system include vegetables, flowers, fruits, grains and the like that make photosynthesis. at the same time, when an irradiation section 60 is not provided, examples of agricultural products intended for the system include bean sprouts, mushrooms that do not photosynthesize and the like. The specific types of plants grown in a hydroponic cultivation system can be appropriately determined by those skilled in the art. The hydroponic cultivation system 100 comprises a frame body 10, containers 20a-20f (hereinafter collectively referred to as “containers 20”), a plurality of plant retaining plates 30, a holding mechanism 40, a pair of transport mechanisms 50a and 50b (hereinafter collectively referred to as "transport mechanisms 50"), a plurality of irradiation sections 60, and a plurality of root cutters 70.
[0021] The frame 10 mainly stores the containers 20. The frame 10 comprises an upper plate 11, a lower plate 12, and support columns 13. The upper plate 11 and the lower plate 12 are rectangular plate elements. The plurality of its edge sections are each equipped with the support column 13.
[0022] The large containers 20 are arranged on the bottom plate 12. As there are several containers 20, they are denoted 20a, 20b, 20c or similar, attaching to, b, c or similar. Containers 20a-20f are arranged in parallel in the transverse direction in that order. In particular, the containers 20a-20f are arranged in parallel in such a way that the longitudinal direction of each container is oriented in approximately the same direction. Containers 20a-20f have accommodation rails 21a-21f (hereinafter collectively called "accommodation rails 21") extending along their longitudinal directions, respectively. The accommodation rails 21 refer to the inner surface of the containers 20. The containers 20 and the accommodation rails 21 can be formed integrally or separately. For example, as reported below, the entire container 20 can be tilted or only the inner surface (bottom surface) of the containers 20 can be tilted to allow a culture solution to flow into the containers 20. When only the inner surface of the containers containers 20 is tilted in this way, this is called accommodation groove inclination 21. A culture solution 3 is stored in accommodation grooves 21. An explanation is provided below, making reference to the direction parallel to the longitudinal direction of containers 20 and the accommodation rails 21 as direction D1 and the direction parallel to the transverse direction of the containers 20 and the accommodation rails 21 as direction D2.
[0023] As is clear from Figure 3, the present invention provides a plant retaining plate above a plurality of elongated containers 20 unlike conventional hydroponic cultivation systems in which a plant retaining plate is soaked in a culture solution in a single container. Therefore, a space would be created between the plant retention plate 30 and the culture solution 3. For that reason, the plant root 2 is sufficiently in contact not only with the culture solution 3, but also with air. As air is sufficiently supplied to the roots of plants 2 thereby, the growth of plants 2 is promoted.
[0024] The plant retention plate 30 is a plate-like member comprising a hollow hole 31. The artificial medium (cultivation bed) 4 comprising the plant 2 is inserted into - and secured by - the hollow hole 31. The plate plant retaining plate 30 is arranged above the containers 20 and is supported by the support mechanism 40. In particular, the plant retaining plate 30 is arranged so as to extend from the container 20a to the container 20f above it. That is, a plurality of containers 20 are under a single retaining plate 30. Conventional hydroponic cultivation systems employ a configuration in which one or more plant retaining plates are arranged over a single large pool-type container.
[0025] The width W of the accommodation chutes 21 in the D2 direction is formed so as to have a thickness that corresponds to the root size of the grown plant 2. For example, the width W is determined to have a thickness such that the root of the plant 2 contacts both side surfaces of the accommodation rails 21. In addition, the width W, for example, is determined so that the space between the root of the plant 2 and each side surface of the accommodation rails 21 is 50 mm or less. In either case, the width W of the accommodation rails 21 is determined to be relatively narrow. In a preferred configuration, the accommodation rails 21 are configured so that the width W of the accommodation rails 21 can be adjusted according to the growth of the plant 2. The width W of the accommodation rails 21 can be configured to be adjusted by known techniques in the matter. Specifically, as the root does not spread in the initial growth periods of plant 2, the width W of the accommodation chutes 21 must be set to narrow and, as the root grows and spreads with the growth of plant 2, the width W of the accommodation rails 21 can be expanded to the point where another mechanism that is present between two adjacent containers (eg, the support mechanism 40, which is present between two adjacent containers and the support mechanism 440 in Figure 7 reported below) ) do not stay in contact with it. It is possible to provide a configuration in which the width of the accommodation rails 21 changes according to the width of the containers 20 or a configuration in which the width is changed independently of the containers 20 and the accommodation rails 21.
[0026] Supply tubes 80a-80f (hereinafter collectively called "supply tubes 80") are provided on the sides of the ends 22a-22f (hereinafter collectively called "ends 22") in the longitudinal direction of the containers 20a-20f, respectively. Supply tubes 80 supply culture solution 3 from a tank 82 via a pump 81 to containers 20. Drainage outlets 24a-24f (hereinafter collectively referred to as “drainage outlets 24”) configured to be open and open closure are provided on the sides of the ends 23a-23f (hereinafter collectively referred to as "ends 23") on the opposite side. The culture solution 3 filled into the containers 20 is drained through the drain outlets 24 and is returned to the tank 82 through a section of receiving water 83 extending in the direction of D 2. The culture solution 3 can be drained by providing a suction pump instead of the drain outlets 24 to pump the solution.
[0027] Accommodation walls 25a-25f (hereinafter collectively referred to as "accommodation walls 25") on the side of the ends 23a-23f of the containers 20a-20f are configured to be detachable. This allows the root of the plant 2 to avoid contact with the accommodation walls 25 when the plant retaining plate 30 is transported towards the root cutter 70. The accommodation wall 25 can be configured to be able to slide downwards or be able to open and close to the left and right or up and down, contact that the accommodation wall 25 can be retracted to avoid contact with the root of the plant 2.
[0028] The holding mechanism can be any mechanism that can support the plant retaining plate 30 above the containers 20. The holding mechanism 40 can be arranged at one end of a plant retaining plate to support the retaining plate left and right plan or disposed between adjacent containers 20 to support the plant retaining plate from below or suspended from above. Examples of such a support mechanism include, but are not limited to, roller, belt, support column, hook and the like. As a specific configuration of the present invention, Figures 1 and 2 show a case where the support mechanism 40 is a roller arranged between containers 20. In the specific configuration, the support mechanism 40 includes groups of support rollers 41ab, 41cd, and 41ef, which are arranged between container 20a and container 20b, container 20c and container 20d, container 20e and container 20f, respectively. Each of the support roller groups 41ab-41ef comprises one or more support rollers 42. In Figures 1 and 2, the support roller groups 41ab-41ef comprise a large number of support rollers 42 arranged with almost no space along direction D1. The support roller 42 is attached to the frame 10 by a support member (not shown). In particular, the support roller 42 is fixed so that its rotational axis is approximately orthogonal to the D1 direction and approximately parallel to the D2 direction. The support mechanism 40 supports, with the possibility of movement, the plant retaining plate 30 with the support rollers 42.
[0029] The general space between the containers 20 can be reduced by having a mechanism such as the support mechanism described above or the space can be left empty without having anything inside it. The light can pass through the containers 20 by the presence of space between the containers 20, so that the light can be radiated on the plant 2 from several directions. In addition, the maintenance of the containers 20 is also facilitated by leaving the space between the containers 20 empty.
[0030] The pair of transport mechanisms 50a and 50b are opposite each other in the D2 direction with the containers 20 between them. Each of the pair of conveyor mechanisms 50a and 50b comprises a plurality of drive rollers 51 and a drive device 52 for rotating and driving the plurality of drive rollers 51. Each drive roller 51 is provided so that the rotational axis it is oriented in the perpendicular direction and the outer peripheral surface contacts the side surface of the plant retaining plate 30. The drive device 52 transmits the rotation of a motor (not shown) to the drive roller 51 through a belt 52a to rotate the drive roller 51. The drive roller 51 in contact with the side surface of the plant retaining plate 30 is rotated in this way to move the plant retaining plate 30. The transport mechanism 50a and 50b can be configured so that an L interval in the D2 direction is adjustable. The system is thus compatible with cases where the length of the plant retention mechanism 30 in the D2 direction is changed due to a design change or the like.
[0031] A plurality of irradiation sections 60 are attached to the upper plate 11. Each irradiation section 60 is disposed opposite the containers 20 in a perpendicular direction. That is, each irradiation section 60 is arranged so as to oppose the plant 2 to be arranged on the container 20 in a perpendicular direction. The irradiation section 60 radiates light, which is received by plant 2 for photosynthesis. The irradiation section 60 does not need to radiate light when growing a plant that does not perform photosynthesis.
[0032] The root cutter 70 is provided in the vicinity of each of the ends 23a-23f, on the opposite side of the ends 22 with respect to the ends 23. In this configuration, the root cutter 70 is a disk-shaped cutter with a plurality of blades arranged at a predetermined interval in the circumferential direction. The root cutter 70 rotates around a rotational axis by a motor (not shown) to cut out the root of the plant 2 which is transported with the plant retaining plate 30. In this way, the root of the plant 2 can be cut while held by the plant retaining plate 30.
[0033] The operation of the hydroponic cultivation system 100 configured as described above is explained below. First, the growth stage is explained. The artificial medium 4 in which the vegetable 2 is planted is then fitted into the hollow hole 31 of the plant retaining plate 30. In addition, the plant retaining plate 30 is arranged in a desired position above the containers 20 by the transport mechanism. 50. The culture solution 3 is then supplied from the supply tube 80 and drained from the drain outlet 24 to circulate the culture solution 3 in the accommodation chutes 21. Naturally, the drain outlet 24 can be closed to retain the culture solution 3 in the accommodation chutes 21. Also, light is irradiated on plant 2 from irradiation section 60 as needed. Plant 2 grows this way.
[0034] The sending stage is explained below. First, the supply of culture solution 3 from the supply tube 80 is stopped to drain the culture solution 3 from the drain outlet 24. Subsequently, the accommodation wall 25 on the side 23 of the containers 20 is detached. While in this state, the plant retention plate 30 is transported towards the root cutter 70. The root cutter 70 cuts the root of the plant 2 that was transported over and with the plant retention plate 30. The plant 2 with its cut root is transported by a transport robot (not shown) and dispatched.
[0035] In the hydroponic cultivation system 100 according to the present configuration, the containers 20 are formed so that the width W of the accommodation rails 21 is relatively narrow. For this reason, the amount of culture solution 3 required for the growth of plant 2 can be reduced. This is extremely advantageous when the hydroponic cultivation system is used, for example, in a region facing water shortages or the like. In addition, since containers 20 are thin and small, culture solution 3 would be circulated quickly. In other words, a fresh culture solution 3 can be successively sent into the 20. For this reason, it is possible to speed up the growth of the plant 2. Also, the interior of the container 20 can be kept clean because the circulation is more fast. In this way, diseases in the plant 2 can be prevented. Furthermore, since a small amount of culture solution 3 is sufficient, the containers 20 would be lighter and the force required for the structure 10 to support the containers 20 would be relatively low. For this reason, the material cost of structure 10 can be kept low. In addition, the durability and pumping performance required for the 81 pump would also be lower, resulting in a reduced cost for the 81 pump.
[0036] Additionally, in the hydroponic cultivation system 100 according to the present configuration, the plant retention plate 30 is supported by the support roller groups 41ab-41ef. That is, the plant retaining plate 30 is supported by a support mechanism provided between the containers. For this reason, the reaction force of the weight of the plant retaining plate 30 from the holding mechanism can be dispersed relatively evenly in the D2 direction. For this reason, the force required for the plant retaining plate 30 would be relatively low, so that a light plant retaining plate 30 can be made. As a result, the drive performance and durability required for the transport mechanism 50 to transport the plant retaining plate 30 would be less, allowing for cost reduction of the transport mechanism 50.
[0037] In addition, in the hydroponic cultivation system 100 according to the present invention, the plant retention plate 30 is provided so as to cover all containers 20a-20f; therefore, plants 2 grown in containers 20a-20f, for example, can be transported together to the dispatch stage when dispatching.
[0038] (Second configuration) The main difference between the hydroponic cultivation system 100 according to the first configuration and the hydroponic cultivation system according to the second configuration is in the formation of the containers.
[0039] Figure 5 shows a hydroponic cultivation system 200 according to the second configuration. Figure 5 corresponds to Figure 3 with respect to the explanation of the first configuration. The hydroponic cultivation system 200 comprises a structure 10, containers 20, a plurality of plant retaining plates 30, a support mechanism 40, a pair of transport mechanisms 50a and 50b, a plurality of irradiation sections 60, and a plurality of root cutters 70.
[0040] A container 120 is configured so that the bottom surface of a trough 126 of its accommodation element 121 is inclined at only an angle θ with respect to the horizontal direction. In particular, the container 120 is configured to have a drop from the side of the end 22, where a supply pipe 80 is provided, towards the side of the end 23, where a drain outlet 24 is provided. the inclination of the lower surface of the trough 126 by supporting the container 120 with an inclination adjustment section 129 and extending and contracting the inclination adjustment section 129. The inclination of the lower surface of the lower surface of the trough 126 can be realized by forming the container 120 so that the lower section 123 is thicker in the direction D1. The inclination can be achieved by tilting the container 120 or tilting the accommodation rail 121 in the container 120.
[0041] Furthermore, a plurality of protruding sections 180 are formed on the lower surface of the trough 126 of the container 120. For example, the protruding sections 180 have a triangular cross section along the D1 direction. As the bottom surface of the trough 126 of the accommodation trough 121 is inclined as described above, a flow of culture solution 3 is created from the end 22 towards the end 23. Turbulence in the flow of the culture solution 3 can be generated. due to the presence of the protruding sections 180. In addition, the present invention has a configuration that supports the plant retaining plate 30 above the container 20 with the support mechanism 40 instead of allowing the plant retaining plate 30 to be submerged on the surface of the culture solution 3 of the container 20. Therefore, there is space between the plant retention plate 30 and the surface of the culture solution 3. Therefore, the air present in the space between the surface of the culture solution 3 and the plate of plant retention 30 is incorporated into the culture solution 3 by the turbulence generated in the culture solution 3. The root of the plant 2 thus not only touches the culture solution 3, but also air, as a result promotes ning the growth of plant 2.
[0042] The hydroponic cultivation system 200 according to the present configuration can achieve the same functional effect as the hydroponic cultivation system 100 according to the first configuration. In addition, the hydroponic cultivation system 200 according to the present configuration has a drop from the supply side towards the drainage side. Therefore, culture solution 3 can be circulated more readily. In addition, the hydroponic cultivation system 200 according to the present configuration can incorporate air into the atmosphere within the culture solution 3.
[0043] (Third configuration) The third configuration explains a hydroponic cultivation system with multiple rows, in which the containers are stacked. Figure 6 is a side view showing a hydroponic cultivation system 300 according to the third configuration. The hydroponic cultivation system 300 comprises a cultivation unit 390 and a crop conditioning unit 392. The entire hydroponic cultivation system of the present invention is configured to have light weight due to the gutter-like shape of the containers 20 extending in one direction. and a lightweight configuration of a plant retaining plate. Therefore, multiple systems of this type can be stacked and arranged vertically, in order to form a multi-row hydroponic cultivation system with a simple mechanism.
[0044] Cultivation unit 390 has a first cultivation shelf 391a, a second cultivation shelf 391b, a third cultivation shelf 391c, and a fourth cultivation shelf 391d (hereinafter collectively referred to as "391 cultivation shelves"), one tank 82, and a pump 81. The first cultivation shelf 391a to the fourth cultivation shelf 391d are stacked in that order from the bottom up. Each of the cultivation shelves 391 comprises a plurality of containers 20, a holding mechanism (not shown), a transport mechanism (not shown), and an irradiation section 60, corresponding to containers 20, holding mechanism 40, transport mechanism 50 and irradiation section 60 in the first and second configurations, respectively. Tank 82 and pump 81 are shared and used by each of the 391. cultivation shelves. Of course, tank 82 and pump 81 can be provided for each 391. cultivation shelf. The display of supply tube 80 is omitted in Figure 6.
[0045] The crop packing unit 392 is provided adjacent to the crop unit 390. In particular, the crop packing unit 392 is provided on the side 23 of the containers 20 in the crop unit 390 (distal side from the end 22), ie, the side proximal to the drain outlet. The crop packaging unit 392 has a transport device 393, a root cutter 70 and a packaging machine 395, which are arranged in that order outwardly from the end 23. The crop packaging unit 392 can have a carrying strap to carry a packaged plant or other device. The transport device 393 comprises a transfer device 394 and an elevator device (not shown). The elevator device loads the transfer device 394 in the perpendicular direction (D3 in the Figure). The transfer apparatus 394 is configured to be able to load the plant retaining plate 30 in the D1 direction. The packaging machine 395 stores plant 2.
[0046] The operation of the hydroponic cultivation system 300 configured as explained above is explained below. First, the growth stage is reported. An artificial medium 4 in which the plant 2 is planted is fitted within a hollow hole 31 of the plant retaining plate 30. The plant retaining plate 30 is then placed on the transfer apparatus 394 by an operator. The elevator apparatus carries the transfer apparatus 394 on which the plant retaining plate 30 is placed in a desired position on D3. For example, when the plant retaining plate 30 is delivered to the second cultivation shelf 391b, the apparatus is moved to a position where the plant retaining plate 30 can be placed on a support mechanism of the second cultivation shelf 391b . The transfer device 394 then delivers the plant retaining plate 30 to the cultivation shelf 391 in the cultivation unit 390. The plant retaining plate 30 is arranged in a desired position above the container 20 by a shelf transport mechanism. of cultivation 391. Also, plant 2 grows as in the case of the first configuration.
[0047] The sending stage is described below. First, the supply of a culture solution from a supply tube is stopped to drain the culture solution from the drain outlet. Next, an accommodation wall 25 on the end side 23 of the container 20 is detached. While in this stage, the plant retaining plate 30 is loaded towards the transport device 393 and placed on the transfer device. The lifting device then loads the transfer device 394 with the plant retaining plate 30 placed on it to a position that corresponds to that of the packaging machine 395. The transfer device 394 loads the plant retaining plate 30 to the machine packaging 395. At that moment, the root of plant 2 is cut by the root cutter 70 provided between the transfer apparatus 394 and the packaging machine 395. The packaging machine 395 then stores the plant 2 with the cut root.
[0048] The hydroponic cultivation system 300 according to the present configuration can achieve the same functional effect as the hydroponic cultivation system 100 according to the first configuration. In addition, the hydroponic cultivation system 300 according to the present configuration places or removes the plant retaining plate 30 with only a 393 transport apparatus. For this reason, the necessary cost for the 393 transport apparatus can be contained.
[0049] The configuration and operation of the hydroponic cultivation system according to the configurations have been explained. These configurations are of an exemplary nature. It is understood by those skilled in the art that several modified examples combining each of the elements that constitute them are possible and that such modified examples are also within the scope of the present invention.
[0050] (First modified example) The three configurations were explained for the cases in which the support mechanism 40 comprises groups of support rollers 41ab, 41cd and 41ef. However, the present invention is not limited to this. A group of rollers 41bc can be provided between the container 20b and the container 20c, and a group of rollers 41de can be provided between the container 20d and the container 20e. Naturally, the support mechanism 40 can comprise any two or more groups of support rollers between the groups of support rollers 41ab, 41bc, 41cd, 41de and 41ef.
[0051] (Second modified example) In the second configuration, a case was explained in which the lower surface of the trough 126 of the container 120 is inclined, ie, a case in which the lower surfaces of the troughs of all the containers 120a-120f are inclined . However, the present invention is not limited to this. It is sufficient that the lower trough surface of one or more of the containers is inclined.
[0052] (Third modified example) The support mechanism 40 and the transport mechanism 50 can be fully configured in the first and second configurations. That is, the support mechanism 40 may have the function of the transport mechanism 50.
[0053] Figure 7 is a top view showing the hydroponic cultivation system 500 according to a modified fifth example. The hydroponic cultivation system 500 comprises a 440 support mechanism. In addition, the 440 support mechanism has a function as the conveyor machine as discussed below. Therefore, the hydroponic cultivation system 500 does not have a transport mechanism 50 as in the first to third configurations.
[0054] The support mechanism 440 has support straps in handle 441ab, 441c and 441ef, driving pulley 442ab, 442cd and 442ef and fixed pulleys 443ab, 443cd, and 443ef, a 444 motor, and a 445 shaft.
[0055] The support straps 441ab-441ef are suspended between the driving pulleys 442ab-442ef and the fixed pulleys 443ab-443ef, respectively The plant retaining plate 30 is supported by the support straps 441ab-441ef. The motor 444 rotates the driving pulleys 442ab-442ef through the axis 445. The support straps 441ab-441ef move in a circular motion through the rotation of the driving pulleys 442ab-442ef, resulting in the plant retaining plate 30 moving in the D1 direction. The support mechanism 440 can have a pulley that guides and at the same time applies tension to the central portion of the belt.
[0056] The present modified form can achieve the same functional effect as the first to the third configuration. In addition, the hydroponic cultivation system 500 of the present modified form does not have a transport mechanism 50. Therefore, the width in its direction D2 can be modified. That is, the space required for the 500 hydroponic cultivation system can be reduced.
[0057] (Fourth modified example) In the third configuration, the crop packaging unit 392 can be configured to be mobile. For example, the crop packaging unit 392 can be arranged on a predetermined track, along which the crop packaging unit 392 is moved. In addition, for example, each apparatus in the crop packaging unit 392 may have a tire to allow the apparatus to move freely with the tire. When a hydroponic cultivation system comprises a plurality of cultivation units 390, the crop conditioning unit 392 configured to be mobile in this way can perform the harvesting and conditioning of the plurality of cultivation units 390. Therefore, the required number of units crop conditioning 392 can be kept low, thus keeping the cost of installing the hydroponic cultivation system low.
[0058] (Another modified example) The space between two adjacent containers can be used effectively in several ways. For example, a mechanism can be provided to receive an overflowing culture solution from a container and send the solution back into circulation. In addition, a mechanism can be provided to prevent the plant retaining plates from running over each other. In addition, the presence of a space between containers facilitates the maintenance of the containers.
[0059] (Artificial medium) Artificial medium 4 is also called the cultivation bed. The artificial medium 4 can have a plant containment portion to hold the plant 2 and can be any element that can be fixed in the hollow hole 31 of the plant retaining plate 30. Typically, the artificial medium 4 can be a fiber article processed vegetable prepared by processing and solidifying coconut fiber or palm or a sponge formed from urethane. However, an artificial medium formed with a fibrous material tends to break, for example, along the fiber shell, and is difficult to handle. Thus, a sponge formed from urethane is particularly preferable in the present invention. Figure 8 is a perspective view showing the artificial medium 4 before being fitted into the hollow hole 31 of the plant retaining plate 30. In one configuration, the artificial medium 4 has a square column shape before being fitted into the hole hollow 31 as shown in Figure 8. Artificial medium 4 is elastically deformed to have a shape corresponding to the hollow orifice 31 when fitted within it. Figures 9 (a) - (c) are expanded view to show the surroundings of the artificial medium 4 fitted in the hollow hole 31 of the plant retaining plate 30. Figure 9 (a) shows a diagram seen from above. Figure 9 (b) shows a diagram seen from below. Figure 9 (c) shows a cross-sectional view along the line D-D in Figures (a) and (b). Figures 9 (a) and (b) show a configuration of the artificial medium 4. Therefore, the display of the plant 2 contained therein is omitted. The artificial medium 4 of the present invention is elastically deformed in an approximately cylindrical shape in the examples shown in Figures 9 (a) - (c). The artificial medium 4 can have a cylindrical shape, polygonal column shape, or any other shape before being inserted into the hollow hole 31.
[0060] The artificial medium 4 has a concave section 4b formed on an upper surface 4a and four concave sections 4d formed on a lateral surface 4c. The first concave section 4b stores at least a portion of the plant 2, such as a portion of the stem or a portion of the root. Thus, the first concave section 4b can be formed with a size and shape that corresponds to the stem or root to be stored. In the present configuration, the first concave section 4b is formed having an approximately cylindrical shape. Plan 2 is maintained by the first concave section 4b.
[0061] A second concave section 4d is formed on each of the 4 lateral surfaces 4c of the artificial medium in the form of a quadrangular column 4. Specifically, the second concave section 4d is formed by creating a notch on a portion of each side surface 4c . The lateral surface 4c has an approximately cylindrical shape when the artificial medium 4 is fitted into the orifice 31. The four second concave sections 4d are aligned equidistant in the direction of circumference on the lateral surface in an approximately cylindrical shape 4c. The four second concave sections 4d extend in the same direction from the lower surface 4e to the upper surface 4a. In this case, they extend to a position below the first concave section 4b.
[0062] When the artificial medium is fitted into the hollow hole 31, an uncut hole 4f is formed by the second concave section 4d and an inner wall 31a of the hollow hole 31. The second concave section 4d may extend from the surface bottom 4e to the top surface 4a. In this case, the second concave section 4d and the inner wall 31a form a hollow hole. The depth of the second concave section 4d can be determined so that the uncut hole 4f is of the desired size considering that the artificial medium 4 deforms elastically when engaged in the hollow hole 31.
[0063] The artificial medium 4 with such a configuration, when fitted inside the hollow hole 31 of the plant retention plate 30, forms the non-poured hole 4f with the plant retention plate 30. For this reason, when the plant root 2 reaches the non-hollowed hole 4f, the root of the plant 2 grows readily from that point onwards. In addition, artificial medium 4 is formed with a sponge in a preferred embodiment of the present invention. Therefore, the root tries to extend evenly in the artificial medium 4. In other words, the root tries to extend so that it remains from the first concave section 4b towards the lateral surface 4c. Thus, the root extends relatively spread out and readily extends in the artificial medium 4 according to the present configuration. Furthermore, since the artificial medium 4 is formed with a sponge, the artificial medium 4 is less susceptible to breakage than in comparison to an artificial medium formed with fibrous material such as rock wool.
[0064] For example, two, three or more second concave sections 4d can be provided on each surface 4c of the artificial medium 4.
[0065] Figures 10 (a) - (c) show a modified example of an artificial medium. Figures (a) - (c) show an artificial medium 204 before being fitted into the hollow hole 31 of the plant retaining plate 30. Figure 10 (a) shows a drawing seen from above, Figure 10 (b) shows a diagram seen from below and Figure 10 (c) shows a cross-sectional view along the EE line of Figures 10 (a) and 10 (b). Artificial medium 204 has a first concave section 4b and a second concave section 4d as in artificial medium 4 in the first and second configuration. In addition, artificial medium 204 has an orifice 204g. The orifice 204g extends in the direction from the lower surface 4e to the upper surface 4e. The orifice 204g may extend in the direction orthogonal to the lower surface 4e or in an inclined direction at a predetermined angle with respect to the lower surface 4e. In addition, orifice 204g may be a hollow or non-hollow orifice.
[0066] The modified modified example can achieve a functional effect similar to the artificial medium 4 shown in Figures 8 and 9. In addition, the artificial medium 204 facilitates the growth of the root by having the orifice 204g in the modified example. The present modified example explained a case in which an orifice 4g is provided in addition to the second concave section 4d. However, hole 4g can be provided instead of the second concave section 4d.
[0067] (Plant retaining plate) The plant retaining plate 30 is a plate-like member comprising the hollow orifice 31. The artificial medium (cultivation bed) 4 comprising the plant 2 is inserted into - and maintained by - hollow hole 31. The plant retaining plate 30 can be supported above the containers 20 and made up of any material in which the hollow hole 31 for holding the plant 2 can be made. The plant retaining plate 30 can be formed from any material, including metal, wood, foamed resin and the like. In a preferred configuration, the plant retaining plate 30 of the present invention is formed with expanded polystyrene foam. The thickness of the plant retaining plate 30 can be determined in accordance with the material or the weight of the plant 2 to be maintained.
[0068] The plant retaining plate 30 is arranged above the containers 20 and supported by the support mechanism 40. In particular, the plant retaining plate 30 is arranged above the 20a up to the container 20f to cover all the containers. The plant retaining plate 30 has a plurality of hollow holes 31 that penetrate from one of the main surfaces to the other main surface. The hollow hole 31 is formed to be positioned perpendicularly above the accommodation chute 21 when the plant retaining plate 30 is arranged above the containers 20. In particular, the hollow hole 31 is formed in each of the accommodation chutes 21a-21f to line up in a row in the D1 direction. In the example shown in Figure 1, 6 rows of hollow holes 31 are formed in the D1 direction to correspond to the 6 accommodation rails, the accommodation rails 21a-21f.
[0069] Each hollow orifice 31 can have any shape that is capable of receiving and maintaining the artificial medium 4 comprising the plant 2 within itself. For example, the hollow hole can be cylindrical, square-shaped, polygonal-shaped or any other shape. Figure 1 shows a circular hole 31 as a representative configuration. The artificial medium 4 in which the vegetable 2 is planted is fitted within each hollow orifice 31. It is not necessary for each hollow orifice 31 and artificial medium 4 to be fitted so as to have their entirety completely in contact. Any form of fitting can be used as long as it achieves the goal of keeping plant 2 in a suitable location. Thus, the hollow hole 31 functions as a retaining section to maintain the plant 2 via the artificial medium 4. For example, a net can be fitted into the hollow hole 31 instead of the artificial medium 4 to hold the plant 2. The leaves from plant 2 protrude out towards the upper side of plant retention plate 30. The root of plant 2 protrudes out from below plant retention plate 30 and contacts culture solution 3.
[0070] (Multi-row cultivation system) A technique to improve the yield of agricultural products, such as plants per unit area using a limited land area, has been desired. Multi-row cultivation shelves are known as such a technique. As disclosed above, the hydroponic cultivation system of the present invention is light. Thus, the system is advantageous for application on multi-row cultivation shelves.
[0071] However, conventional multi-row cultivation shelves, including those described in Japanese patent publication No. 2012217392, radiate light only from the lighting provided on the top side of each row. For this reason, conventional multi-row cultivation shelves presented a problem with insufficient light irradiation on agricultural products. To solve this problem, light can be radiated from several directions. However, irradiation of light from multiple directions on multi-row cultivation shelves was considered difficult.
[0072] In this regard, the inventors have developed a plant retaining plate 35, which is a modified example of the plant retaining plate 30, in the hydroponic cultivation system of the present invention. In addition to the hollow hole 31, the plant retention plate 35 shown in Figure 11 comprises a light permeation region 28 regardless of the hollow hole 31. The plant retaining plate of the modified example can be used not only in the hydroponic cultivation system shown in Figures 1-6, but also as a floating plate in conventional hydroponic cultivation systems. That is, the plant retaining plate 35 can be formed as a floating plate with a material that floats in the water. Expanded polystyrene foam can be suitably used as the material for such a plant retention plate 35. The thickness of the plant retention plate 35 can be determined depending on the material or the weight of the agricultural product 22 to be grown. The plant retaining plate 35 can be of any shape, which can be determined in accordance with the hydroponic cultivation system in which the plant retaining plate 35 is used.
[0073] The hollow hole 31 is formed so as to penetrate from one of the main surfaces of the plant retaining plate 35 to the other main surface to retain the plant 2. It is preferable that a plurality of hollow holes 31 are formed over the plant retaining plate 35. Figure 13 is used below to describe how the plant 2 is maintained by the hollow hole 31.
[0074] The light permeation region 28 is also formed from one of the main surfaces of the plant retaining plate 35 to the other main surface to allow light to pass through. The light permeation region 28 is provided adjacent to the hollow hole 31 so that the light is radiated over the plant 2, when the plant 2 is maintained, at least at the bottom of the plant retaining plate 35 even if the plant 2 grow up. The light permeation region 28 preferably accounts for about 30% or more - and more preferably, about 50% or more, of the surface area on both main surfaces of the plant retaining plate 35. "About" here it refers to a value in the range of the subsequent number up to ± 10%. When the light permeation region 28 is less than 30%, the amount of light irradiated on plant 2 may not be sufficient. Meanwhile, the efficiency of light irradiation can be significantly increased by making the light permeation region 28 about 50% or more. The surface area of the light permeation region 28 can cover, for example, about 80%, as long as the total strength of the plant retaining plate 35 is not compromised. The light permeation region 28 can have any shape and be made of any material, as long as the light coming from a light irradiation source can be at least partially passed through. In the configuration shown in Figure 11, the light permeation region 28 is a hollow orifice. However, the light permeation region 28 can be formed as a transparent, non-penetrated window made of glass or resin.
[0075] A series of light permeation regions 28 can be called light permeation region 28a, light permeation region 28b and light permeation region 28c, according to their respective shape and position. The light permeation region 28a is provided between adjacent retaining sections 26 in the longitudinal direction of the plant retaining plate 35. The light permeation region 28b is provided between two retaining sections 26 around a corner of the retaining plate plant 35 in the transverse direction of the plant retaining plate 35. The light permeation region 28c is provided between two retaining sections 26 in a region other than the periphery of the corner of the plant retaining plate 35.
[0076] The plant retaining plate 35 shown in Figure 11 can be used to allow light to be efficiently radiated over plant 2 from various directions. As a result, the level of plant growth can be increased, improving productivity.
[0077] In this regard, Figures 12 and 13 are used to explain a culture system 1000 using the plant retention plate 35. Figure 12 is a front view, showing a Culture system 1000 using the plant plate plant retention 35 according to a configuration. Figure 13 is a side view showing the culture system 1000 using plant retaining plate 35. In Figure 12, the illustration of the irradiation section 61 and reflector plates 18 and 19 is omitted.
[0078] The Culture System 1000 comprises mainly the plant retaining plate 35, the structure body 10 and the irradiation section 60.
[0079] The frame body 10 is formed by arranging a series of containers 20 in a vertical direction at a predetermined interval. Containers 20 have gutter-shaped accommodation spans 21 to accommodate culture solution 3. Unlike hydroponic cultivation systems 100-300, hydroponic cultivation system 1000 is provided with a series of convex portions 14 on each opposite surface of inner wall of structure 10. Both ends of the containers 20 are placed in the convex sections 14 provided at the same height to fix each of the series of containers 20 in the structure 10. In addition, a cylindrical irradiation section 16 is provided between a pair of containers 20 adjacent in the vertical direction. No structure body is provided for the irradiation section 16 in the present configuration, in order to be able to radiate light in the upper and lower directions. However, the structural body can be provided. When such a structure is provided in the irradiation section 60, it is preferable that the structure be formed transparent or semitransparent so that the light passes through. Each end of the irradiation section 60 is fixed under the convex section 14, so that the containers 20 and the irradiation section 60 are parallel. Only the top three rows of the cultivation shelves are shown here. However, the hydroponic cultivation system 1000 can be a system comprising any number of rows on the cultivation shelves, 4 or more.
[0080] Figures 12 and 13 are used again to explain the relationship between containers 20 and plant retaining plate 35 of culture system 1000. Accommodation trough 21 of container 20 stores culture solution 3 and plate plant retention plate 35. Plant retention plate 35 holds plant 2 while the plant is contained in a pot 32. Pot 32 stably holds plant 2, regardless of the growth stage, while plant 2 is in a stage into which the hollow orifice 31 is penetrated. The vessel 32 may be the artificial medium 4 mentioned above or the artificial medium 4 may be fitted to the vessel 32. The leaves of the plant 2 are mainly fixed while projecting outwardly and upwards from one of the main surfaces of the retaining plate of plant 35. Meanwhile, the root of plant 2 protrudes out and down from the other main surface of plant retaining plate 35 and comes in contact with culture solution 3. A hole is drilled in pot 32 to allow culture solution 3 to enter into pot 32 and contact the root of plant 2 and allow light to radiate to the root. The root of plant 2 can also penetrate the open hole in pot 32 and grow out of pot 32. A hole as large as possible is desirable as long as plant 2 can be contained. The vessel 32 can be integrally formed with the plant retaining plate 35. In addition, an artificial medium 4 such as a sponge can be provided within the vessel 32.
[0081] The following explains the irradiation of light to plant 2 maintained by plant retaining plate 35. The explanation is provided here by attaching "a" and "b" to plant retaining plate 35, plant 2, containers 20 and irradiation section 60 of the upper row and the middle row, respectively, of the three-row structure shown in Figures 12 and 13.
[0082] At least the bottom surface of the container 20a in the top row is light permeable for the pair of containers 20a and 20b, preferably semitransparent or transparent - more preferably, transparent. In this case, the light radiated from the irradiation section 60a provided on the upper side of the container 20a of the upper row is mainly irradiated on the nearest plant 2a (dotted line P in Figure 12) when the plant retaining plate 35a holding the plant 2a to be cultivated and the culture solution 3 are stored in the container 20a of the upper row. In addition, the light radiated from the irradiation section 60b provided between the container 20a and the container 20b irradiates not only the plant 2b, but also the plant 2a by crossing the light permeation region 28b (dotted line Q in Figure 12 ). The light from the bottom side is mainly radiated on the back side of the leaves. In addition, the light from the back side is also radiated over the root of the plant 2. Also, the light irradiated from the radiation section 60a provided in the upper row crosses the light permeation region 28c and is irradiated over the plant 2b maintained by the plate of plant retention 35b on the bottom row (dotted line R in Figure 12). The lateral surface, in addition to the lower surface, of the container 20 is preferably light permeable, more preferably semitransparent or transparent and, more preferably, transparent to allow the irradiation of light from the irradiation section 60 in various positions. In a particularly preferred configuration, all containers 20 are transparent. It is preferable to use a material such as glass or polycarbonate when forming a container 20 to be transparent. In addition, it is preferable that pot 32 is also formed transparent to increase the efficiency of light irradiation at the root of plant 2a.
[0083] In addition, as shown in Figure 13, the reflector plate 18 is provided around the irradiation section 60b in the horizontal direction. The reflector plate 18 changes the direction of progression of light released from the irradiation section 60 towards the plant 2 as shown by the dotted lines S and T. The light is thus radiated over at least between: the plant 2a maintained by the retention plate of plant 35a stored in container 20a in the top row or plant 2b maintained by plant retaining plate 35b stored in container 20b in the bottom row.
[0084] In addition, an irradiation section 61 is provided around both ends of the container 20. The irradiation section 61 radiates light on the plant 2 from the side surface. The irradiation section 61 is provided with reflective plate 19 having a curved cross section. The reflector plate 19 reflects light scattered outside the hydroponic cultivation system 1000 to irradiate the plant 2.
[0085] In view of the above, the plant retaining plate 35 of the present configuration can be used to cause multi-row crop to efficiently radiate light from various directions on the cultivated plant 2. As a result, the growth level of the plant 2 is perfected, improving productivity.
[0086] Furthermore, the proportion of the light permeation region 28 responsible for the surface area of the plant retaining plate 35 at a predetermined value or above it allows the efficiency of light irradiation to be even better. In addition, the processing capacity and loading / unloading efficiency of the plant retaining plate 35 can be improved by forming the plant retaining plate 35 with a material that floats in water.
[0087] Furthermore, the light can be efficiently irradiated on the plant 2 grown from several directions by building the culture system 1000 with the plant retention plate 35 of the present configuration. In particular, light can be radiated over not only the upper side of the leaves of plant 2, but also on the rear side and at the root. As a result, the level of growth of plant 2 is improved and productivity improves. In fact, the inventors confirmed that the growth of plant 2 shows a significant improvement by radiating light on not only the anterior side of the leaves of plant 2, but also on the posterior side and on the root using the 1000 culture system. In addition, the efficiency of irradiation of light can be even better using the reflector 18 to reflect the irradiated light of the irradiation section 60.
[0088] The plant retaining plate 35 is formed with a material that floats on water in the present configuration. However, the plant retaining plate 35 can be formed with a material that does not float in water. In that case, the objective of the present invention can also be achieved using, for example, a transparent or similar glass or resin or mesh, to allow the light to pass through the plant retention plate itself 35. The efficiency of light irradiation on plant 2 can thus be improved.
[0089] In addition, plant 2 can float on water by forming vessel 32 with material that floats on water, such as expanded polystyrene foam. In this case, it is preferable to provide the light permeation region 28 in the vessel 32. In this case, the vessel 32 can be integrally formed, in the shape of a hat, for example, providing a flange section where the region of light permeation 28 is provided on the outer circumference of the opening.
[0090] Furthermore, the present configuration shows a case in which a plant retaining plate 35 is stored for each container 20 in each row. However, a series of plant retaining plates 35 can be packaged. In this case, the light can be efficiently irradiated on the plant 2 by at least one of: prepare a series of plant retaining plates 35 with different positioning of the light permeation region 28 and hollow orifice 31; change the positioning of the irradiation section 60; and changing the positioning or shape of the reflector plate 18. In addition, the plant retaining plate 35 can be arranged above several containers 20 extending in a predetermined direction as in the hydroponic cultivation systems 100-30a0 mentioned above. In this form of representation, the light can pass between two adjacent containers and the configuration of the plant retaining plate 35, irradiation sections 60 and 61 and reflecting plate 18 as described above can be combined. Therefore, a large amount of light would be radiated on the plant 2 from a large number of directions.
[0091] As disclosed above, another configuration of the present invention is a multi-row culture system. The culture system comprises the aforementioned plant retention plate, culture shelves on which are placed, in the vertical direction, several containers having a concave section to accommodate a culture solution, and an irradiation section provided between a pair of containers adjacent in the vertical direction. For the pair of containers, at least a portion of the bottom surface of the container at least the top row is transparent. The light can pass through the light permeation region and the container in the top row to radiate a plant maintained by a plant retention plate from an irradiation section when the plant retention plate that holds the plant cultivated and the solution of culture are stored in the culture vessel in the top row. The light can be efficiently radiated onto the crop plant from several directions using the plant retention plate of the present configuration to conduct multi-row culture.
[0092] In addition, a reflective plate can also be provided in a culture system in order to change the direction of progression of light released from the irradiation section towards the plant around the irradiation section. This configuration can further improve the efficiency of light irradiation by radiating scattered light to at least one among: plant maintained by a plant retention plate stored in a culture container in the top row or plant maintained by a plant retention plate stored in a container in the bottom row. As a result, the level of plant growth can be improved, improving productivity.
[0093] (Loading / unloading system) Cultivation shelves with multiple rows such as those described above presented the problem that more work was needed to load / unload as the number of rows increased and the shelves became taller. For example, the technique of Japanese patent publication No. 2012217392 manually loads / unloads the plant from the cultivation shelf. In addition, it was necessary to ensure a working space equal to or greater than the floor area of a cultivation shelf around the cultivation shelves. For that reason, the yield per unit area could be improved
[0094] Therefore, the present invention provides a technique that facilitates loading or removing a plant from a cultivation system with several rows.
[0095] The culture system of a given configuration of the present invention comprises cultivation shelves in which several containers to accommodate a culture solution are provided in parallel in the vertical direction and a loading device for loading in at least one between several containers , a plant retention plate to hold a plant that contacts a culture solution and is cultivated when stored in an accommodation chute and disposed in close proximity to one end of the cultivation shelves. The loading device comprises a vertical transport mechanism for raising the plant retaining plate to a height where the plant retaining plate must be arranged on each cultivation shelf and a horizontal transport mechanism for pushing at least one plant retaining plate. plant retention next to a series of plant retaining plates packed in a container where the plant retaining plate must be packed, from the side of one end in an approximately horizontal direction, to have the series of retaining plates of plant confined and sliding to the other end on the side opposite that of said one end.
[0096] A plant retention plate can be readily loaded into the multi-row cultivation shelf with this configuration.
[0097] In addition, a culture system may further comprise an unloading device for unloading, from a container, the plant retaining plate slid in a positioning section provided on the container close to the other end and disposed close to the other end. In that case, the loading device and the unloading device can alternatively load / unload. The plant retaining plate can be loaded / unloaded promptly in this configuration. Also, in this case, the reserved space may be small on the side surface of the cultivation system. For this reason, more cropping systems can be arranged in parallel, significantly increasing the amount of plant production per unit area.
[0098] In addition, a loading device can load, at one time, one or more plant retaining plates on each of the two or more cultivation shelves arranged in the vertical direction. In this configuration, a plant retaining plate can be more effectively loaded / unloaded from a multi-row shelf.
[0099] Also, the number of shelves loaded / unloaded at once can be a factor in the number of rows in the series of cultivation shelves arranged in the vertical direction. This configuration can load / unload a plant retaining plate efficiently.
[0100] In addition, the system may also comprise a loading conveyor belt to supply a plant holding plate with a plant to be grown in a loading apparatus. This configuration can load a plant retaining plate more efficiently.
[0101] First, a 1000 'culture system of the present configuration is explained with reference to Figures 14-16. Figures 14-16 explain a loading / unloading mechanism of the present invention using a multi-row hydroponic cultivation system, which allows the plant retention plate to float in a culture solution. However, the loading / unloading mechanism of the present invention can also be used in the hydroponic cultivation systems described above, from configurations 1-3, supporting a plant retaining plate above a container with a holding mechanism (ie, there are a space between the plant retaining plate and the culture solution). Figure 14 is a schematic diagram of the culture system 1000 'comprising the loading / unloading mechanism of the present invention. Figure 14 (A) is a side view of the 1000 'culture system, and Figure 14 (B) is a plan view of the 1000' culture system. Figure 15 is a front view of the culture system 1000 'in Figure 14 seen from the direction of the arrow X in Figure 14. Figure 14 omits the illustration of the cargo conveyor belt 400 shown in Figure 15. In addition, Figure 14 (B) omits the illustration of the upper plate 340 and the irradiation section 60 provided on the rear side of the upper plate 340 shown in Figure 14 (A). In addition, Figure 15 only shows a loading device 100 'and a load carrying belt 400.
[0102] The culture system 1000 'comprises mainly comprising the loading device 100', a loading device 200 ', a culture shelf 300', and the load carrying belt 400.
[0103] The culture shelf 300 'is formed while several of culture vessels 310 with approximately the same shape and with a concave trough-shaped section 312' are provided in parallel in the vertical direction at predetermined intervals. A positioning section 314 is formed into a concave section 312 '. In addition, a culture solution 3 for hydroponic cultivation is packaged in the concave section 312. Culture solution 3 is an aqueous solution prepared by dissolving nutrients that are capable of growing a plant in water. A fixing member 320 secures said series of containers 310 in the vertical direction. Figure 14 shows a case in which 12 culture vessels 310 are fixed with the holding member 320. The holding member 320 is fixed to the floor in the holding section 322. The irradiation section 60 is installed on the rear surface of the holding vessel. culture 310 other than the bottom row. The irradiation section 60 radiates light on the plant and holds in the culture vessel 310 a row down while the culture vessels 310 are arranged in the vertical direction. The light is irradiated in the culture vessel 310 on the topmost row by the irradiation section 60 provided on the rear surface of the upper plate 340.
[0104] The plant retention plate 30 holds plant 2 to be cultivated as described above and is in contact with culture solution 3 when packaged in concave section 312. Hollow hole 31 (not shown) for fixing plant 2 to be cultivated is opened on the plant retention plate 30. The plant 2 to be cultivated is arranged to penetrate through the hollowed hole so that the root of the plant 2 to be cultivated contacts the culture solution 3 from the lower side of the plant retention plate 30. Culture solution 3 can thus be placed on plant 2 to be cultivated. The plant retaining plate 30 can be composed of any material that has the hollow hole 31 to hold the plant 2 made inside and be stored in the concave section 312. The plant retaining plate 30 can be formed of any material including metal, wood, foamed resin and the like. In configurations in which the plant retaining plate 30 is immersed in the culture solution, the plant retaining plate 30 is preferably formed with a material with a specific gravity of less than 1 to cause the plant retaining plate 30 float in culture solution 3 even while holding plant 2 to be cultivated. Polystyrene foam can be used optimally as such material. The material or volume of the plant retaining plate 30 can be determined by considering the weight of the plant 2 to be grown.
[0105] In addition, the plant retaining plate 30 can be the plant retaining plate 35 which has not only the hollow hole 31, but also the light permeation region 28.
[0106] The charging device 100 'is arranged around one end of the culture shelf 300' and carries the plant retention plate 30 that holds the cultivated plant 2 by counting the culture solution 3 when packaged in the concave section 312 inside of at least one among the various culture vessels 310. The loading device 100 is constructed so as to have any mechanism that can transport the plant holding plate in the vertical direction to a culture vessel of interest and carrying the holding plate plant horizontally when it reaches the culture container of interest to place the plant retaining plate within a concave section of the culture container in a multi-row hydroponic cultivation system. In the specific configurations shown in Figures 14 and 15, the loading device 100 'comprises a transport section 110, a vertical motor 122, a vertical roller chain 130, a horizontal motor 140, a horizontal roller chain 150 and a section of control 160.
[0107] The transport section 110 has a series of retaining sections 114 installed in the securing section 112. As shown in Figure 15, the retaining section 114 is formed from two arms. The retaining section 114 holds the plant retaining plate 30 when loading / unloading. In addition, as explained in Figure 16, the retaining section 114 is provided with a pushing section 116. The pushing section 116 is pushed to slide the plant retaining plate 30 in the horizontal direction.
[0108] The vertical motor 112 rotates and moves the vertical roller chain 130, thus the rotational movement of the vertical motor 122 is converted into movement of the transport section 110 in the vertical direction (up and down transport). The horizontal motor 140 rotates and moves the horizontal roller chain 150, thus the rotational movement of the horizontal motor 140 is converted into movement of the transport section 110 in the horizontal direction (left and right direction)
[0109] The control section 160 controls the rotation of the vertical motor 122 and the horizontal motor 140 to control the movement of the transport section 110 in the vertical direction and in the horizontal direction. In addition, the control section 160 communicates with the control section 260 provided in the unloading device 200 'discussed via wired or wireless communication to coordinate the loading of the plant retaining plate 30 by the loading device 100' and unload the plant retaining plate 30 by the unloading device 200 '. In addition, control section 160 controls the time to load the plant retaining plate 30 into the loading device 100 'of the load carrying belt 400 mentioned below.
[0110] The 200 'unloading device can have any mechanism that takes the plant retaining plate packaged in a culture container of interest from the culture container and transports the plant retaining plate for harvest in a cultivation system hydroponic with multiple rows. In a specific configuration shown in Figures 14 and 15, the discharge device 200 'is disposed in proximity to the other end and discharges, from the culture vessel 310, the plant retention plate 30 slid into the positioning section 314 provided on the culture vessel 310 in the vicinity of the other end. The unloading device 200 'comprises a transport section 210, a vertical motor 220, a vertical roller chain 230, a horizontal motor 240, a horizontal roller chain 250, and the control section 260.
[0111] Transport section 210 has a series of retaining sections 214 installed over a securing section 212. When unloading, plant retaining plate 30, on which plant 2 after cultivation is placed, is held by the sections retainer 214.
[0112] The vertical motor 220 rotates and moves the vertical roller chain 230, thus the rotational movement of the vertical motor 220 is converted into movement of the transport section 210 in the vertical direction (transport up or down). The horizontal motor 240 rotates and moves the horizontal roller chain 250, thus the rotational movement of the horizontal motor 240 is converted into movement of the transport section 210 in the horizontal direction (left and right direction).
[0113] Control section 260 controls the rotation of the vertical motor 220 and the horizontal motor 240 to control the movement of the transport section 210 in the vertical direction and in the horizontal direction. In addition, the control section 260 communicates with the control section 160 provided in the charging apparatus 100 'reported above via wired or wireless communication to coordinate the loading of the plant retaining plate 30 by the charging device 100 'and the unloading of the plant retaining plate 30 by the unloading device 200'.
[0114] The loading device 100 'and the downloading device 200' are explained here as separate devices. However, they can be configured to be the same device.
[0115] As shown in Figure 15, the load carrying belt 400 sends the plant retaining plate 30 that holds the plant 2 to be cultivated to the loading device 100 '. The cargo conveyor belt 400 has a structural body 410 and a series of rotation beds 420. The series of rotation beds 420 is formed in such a way that the height of each one is approximately the same as the height of each one. retaining sections 114 when transport section 110 goes down. In this state, the rotation beds 420 are rotated by the control section 160 to provide new culture equipment 20 for the retention section 114.
[0116] Next, the culture system 1000 'of the present configuration is used to explain a method of loading the plant retaining plate 30 into or out of the culture container 310. Figure 16 is a schematic view from from the side direction, showing the procedure for alternately loading the plant retaining plate 30 into / out of the 1000 'culture system according to the present invention. It is assumed here that a main transport mechanism is composed mainly of transport section 210, vertical motor 220, and vertical roller chain 230, and the horizontal transport mechanism mainly composed of retaining section 214, horizontal motor 240, and horizontal roller chain 250, respectively. However, the vertical transport mechanism can be the transport section 210 and the horizontally transport machine can be the retaining section 214, for simplicity. In addition, the explanation is provided with reference to a plant retaining plate discharged by the discharge device 200 'as a plant retaining plate 30a; the plant retaining plate adjacent to the plant retaining plate 30a discharged by the discharge device 200 'as a plant retaining plate 30b; a plant holding plate loaded on the loading device 100 'as a plant holding plate 30c, and a plant holding plate loaded by the loading device 100' subsequent to the plant holding plate 30c as a holding plate 30d plant.
[0117] First, the control section 260 moves the retaining section 214, which is the horizontal transport mechanism of the discharge device 200 ', into the culture solution 3 (Figure 16 (A)). Retention section 214 is lowered into culture solution 3 in a position closer to the discharge device 200 'than positioning section 314. Figure 16 (B) is a diagram showing the state after the section retainer 214 is moved into the culture solution. The retaining section 214 is then moved horizontally towards the plant retaining plate 30a (Figure 16 (C)). After the retaining section 214 is moved to a position where the plant retaining plate 30a can be lifted in the vertical direction, the retaining section 214 raises the plant retaining plate 30a in the vertical direction to remove the plant retaining plate. plant 30a of culture solution 3 (Figure 16 (D)). In this regard, the retaining section 214, which is the horizontal movement mechanism of the loading device 100 ', carries the plant retaining plate 30c. The discharge device 200 'then discharges the plant retaining plate 30a that has been removed (Figure 16 (E)). The plant retaining plate 30a discharged from the culture vessel 310 is discharged from the culture system 1000 'when the transport section 210 is brought down. In addition, the holding section 214 of the loading device 100 'moves the plant holding plate 30c into the culture solution 3.
[0118] The push section 116 pushes and slides the plant retaining plate 30c in the horizontal direction (arrow in Figure 16 (F)). The push section 116 pushes the plant retaining plate 30c as close to the loading device 100 'in order to push all the plates in the plant retaining plate series 30 packed in a certain concave section 313 in one direction approximately horizontal. The plant retaining plates 30 accommodated in a single culture vessel 310 are thus collectively collected and slid towards the opposite side end. As a result, the plant retaining plate 30 is moved together until the plant retaining plate 30b closest to the unloading device 200 'reaches positioning section 314 (Figure 16 (G)). Various plant retaining plates 30 can be readily brought together and moved together to form the plant retaining plates 30 with a specific low gravity material such as expanded polystyrene foam. After the plant retaining plate 30b is moved to positioning section 314 by the retaining section 114 of the loading device 100 ', the retaining section 114 is placed below the surface of the water so that the plant retaining plate 30c float on culture solution 3 (Figure 16 (H)). The retaining section 114 of the loading device 100 'is subsequently moved horizontally towards the loading device 100' and separated from the plant retaining plate 30c (Figure 16 (I)). The controller 160 then lowers the transport section 110 to the bottom and moves the load transport belt 400 to position the plant retaining plate 30d that holds plant 2 prior to cultivation on the retaining section 114. The retaining plate of plant 30d is subsequently supplied to the culture vessel 310.
[0119] The plant retaining plates 30 of the culture vessel 310 can be replaced by repeating Figures 16 (A) - (I) mentioned above. When the plant retaining plates 30 that hold the plant 2 before cultivation are replaced by the plant retaining plates 30 that hold the plant 2 after cultivation, after a certain culture period has passed, the operations in Figures 16 ( A) - (I) the number of times equal to the number of plant retention plates 30 packed in the culture container 310 can be repeated to replace the plant retention plates 30.
[0120] An example of loading the plant retaining plates 30 into / out of a culture vessel 310 has been shown here. However, it is preferable that several retaining sections 114 and retaining sections 214 installed on the loading device 100 'and unloading device 200', respectively, are used to load the plant retaining plates 30 into / out of the containers. of culture 310 at once. In that case, the culture system 1000 'shown in Figures 14 and 15 first replaces three rows of adjacent culture vessels 310 and, after all replacement is completed, replaces the next three rows. The time required to load / unload can thus be reduced substantially.
[0121] In this case, each of the: number of plant retaining plates 30 loaded / unloaded at once, number of retaining sections 114 and number of retaining sections 214 used at one time, is preferably a factor of number of several culture vessels 310 arranged vertically on the culture shelf 300. For example, the culture shelf 300 has 12 rows of culture vessels 310 in Figure 14. Therefore, it is preferable that the plant retaining plates 30 to be loaded / unloaded into 2, 3, 4, 6, or 12 rows of 310 culture vessels at a time. The loading / unloading can thus be carried out effectively. In addition, the retaining sections 114 and the retaining sections 214 can be constructed larger in order to load several plant retaining plates 30 at once into / out of a single culture vessel 310.
[0122] Also, when the culture vessel 310 is not at full capacity of the plant holding plates 30, the plant holding plate 30 can be loaded into the culture vessel 310 using only the loading device 100 'without using the 200 unloading device'. In addition, Figure 16 shows a case in which the plant retaining plate 30 is loaded out first and then loaded inwards afterwards. However, the 1000 'culture system can be configured to load the plant retaining plate 30 first and then unload it later.
[0123] In view of the above, the culture system 1000 'of the present configuration can load the plant retention plate 30 into / out of the culture shelf 300'. Still, in that case, the space held on the side of the culture shelf 300 'can be small. For this reason, more 1000 'crop system can be arranged in parallel per unit area. Thus, the amount of organism production per area can be significantly increased.
[0124] It is preferable that both the loading device 100 'and the loading device 200' are provided in the culture system 1000 '. However, only one of the two can be provided. In that case, a person can play the role of the device that is not provided. The plant retaining plates 30 can be readily loaded into or out of the multi-row culture shelf 300 'in this way.
[0125] Furthermore, in the present configuration, the positioning section 314 is formed on the side of the discharge device 200 'of the culture vessel 310. However, the positioning section 314 can be formed on the side of the loading device 100 ', whereby the plant retaining plate 30 can be prevented from moving to the side of the loading device 100'. Furthermore, it is preferable, in that case, to form the positioning section on the side of the loading device 100 'so that the distance from the end of the culture vessel 310 on the side of the loading device 100' to the positioning section on the side of the loading device 100 'is equal to the distance from the end of the culture container 310 on the side of the loading device 200' to the positioning section 314. In this way, culture container 310 can be used regardless of orientation.
[0126] In addition, a discharge conveyor with a structure similar to that of the cargo conveyor 400 may be provided for the discharge device 200 '. In such a discharge conveyor, when installed adjacent to the discharge device 200 ', the rotation beds are rotated in the direction in which the plant retaining plates 30 are discharged. The unloading conveyor belt can thus unload the plant retaining plates 30 that hold the plant 2 after cultivation from the unloading apparatus 200 '. In addition, the loading conveyor belt 400 and a discharge conveyor belt can be provided to the culture vessels up to a higher row or the number to reduce the time of the loading device 100 'and the unloading device 200' moving it. up and down.
[0127] For example, when the hydroponic cultivation system of the present invention is used to grow plants that grow in a month, 12 times the plants can be grown in one month per area. The culture equipment 20 is readily loaded / unloaded as described above in the culture system 10 of the present configuration. For this reason, 12 x 12 = 144 times of plants can be grown in one year per area.
[0128] (Hydroponic cultivation system accommodation greenhouse) The present invention provides not only a hydroponic cultivation system, but also a combination of such a hydroponic cultivation system and a greenhouse for its accommodation. In the present invention, a combination of a hydroponic cultivation system and a greenhouse to accommodate the system is referred to herein as a "vegetable factory". The greenhouse to accommodate the hydroponic cultivation system of the present invention is not particularly limited to, but is preferably, a greenhouse with a high level of thermal insulation effect. This is due to the fact that there is no seasonal variation in the internal temperature and the vegetable of interest can be stably cultivated and harvested throughout the year due to the effect of the high level of thermal insulation and to no effect of the external environment.
[0129] In one configuration, a greenhouse to accommodate the hydroponic cultivation system of the present invention is a greenhouse made of foamed resin with thermal insulation property. As used herein, "foamed resin" refers to a synthetic resin with gas dispersed within it and molded in the form of foam. The synthetic resin in the present invention can be any synthetic resin capable of being molded by means of foam molding, while the foam molding product can accommodate a hydroponic cultivation system. However, the synthetic resin is preferably of expanded polystyrene foam. A foam hydroponic cultivation system using expanded polystyrene foam as a material is resistant to damage, unlike conventional vinyl greenhouses, and can sufficiently withstand natural disasters such as earthquakes and typhoons. In addition, even if the surface of the greenhouse breaks due to an earthquake or the surface of the greenhouse is partially deformed by collision with an object during a hurricane, such damage can be easily repaired. In comparison to ordinary architectural structures and glass greenhouses, a greenhouse made of expanded polystyrene foam is much less susceptible to breakage during a natural disaster. In addition, glass is not used for the greenhouse surface. Thus, there is no concern about shattered glass flying or being spread inside the greenhouse. Also, once the wall surface is thick enough, an impact from the outside can be prevented from reaching the interior of the greenhouse. For this reason, an expanded polystyrene foam greenhouse would not be warped by the wind as it would in a vinyl greenhouse, nor would it cause damage to crops due to the breakdown of the vinyl.
[0130] As the expanded polystyrene foam has excellent thermal insulation and light blocking properties, the environment for the growth of a vegetable (vegetables, fruits or similar) grown in a greenhouse, that is, temperature, humidity, irradiation time light and the like, can be easily controlled. Thus, plants can be stably cultivated and harvested throughout the year without being affected by external climatic conditions with hydroponic cultivation. In addition, expanded polystyrene foam can be easily recycled.
[0131] The greenhouse hydroponic cultivation system of the present invention comprises a means of adjusting the ambient temperature to adjust the temperature inside a greenhouse as needed. A greenhouse made of expanded polystyrene foam, which is a preferred configuration of the present invention, shows little variation in ambient temperature inside the greenhouse compared to other greenhouse hydroponic cultivation systems (for example, conventional vinyl greenhouses and the like) due to the excellent thermal insulation effect and hermetic properties of expanded polystyrene foam. For this reason, a large-scale room temperature adjustment inside the greenhouse is unnecessary, so that the cost associated with means of adjusting the temperature of the location can be reduced.
[0132] In addition, a hydroponic cultivation system with a greenhouse can be a prefabricated expanded polystyrene greenhouse, built by assembling a series of divided fragments, so that the greenhouse is completed in a shorter construction period, at a lower cost than the whole construction of a vegetable factory. The system. The hydroponic greenhouse cultivation system of the present invention may comprise equipment, such as a reflective material to reflect light radiated from an irradiation apparatus.
[0133] Divided fragments that constitute an expanded polystyrene foam stove are, for example, molded products of expanded polystyrene foam with a thickness of about 10-50 cm and an expansion coefficient of about 10-50 times. For example, when the greenhouse serves to be installed in a region that needs a higher level of resistance, with the possibility of snow of up to about 80 cm, divided fragments can be made of expanded polystyrene foam, with a thickness of about 20 cm and an expansion coefficient up to about 20 times to ensure strength. The thickness increases with a higher expansion rate. In addition, in regions where snowfall does not need to be considered, an expansion index greater than about 20 times or a thickness of about 20 cm or less can be used. In contrast, in regions with snow of 1 m or less, the expansion rate is reduced to about 20 times or less to ensure strength, or the thickness is increased. This type of expanded polystyrene foam has an excellent light blocking property, capable of cutting off light from outside. The specific shape of the divided fragments of a prefabricated expanded polystyrene foam stove and the specific method of assembling them are known in the art and can be selected appropriately by those skilled in the art.
[0134] In a split fragment assembly configuration to build a greenhouse, it is preferable to secure the divided fragments by connecting. Examples of such connection means include, but are not limited to, structures such as tie straps, wire cables, piano strings, rubber, nets, mortar and the like. For example, it is preferable to tie a strip around a prefabricated greenhouse in the circumferential direction, in such a way that the divided fragments that are fixed and glued together do not disassemble. Alternatively, a flexible steel cable or piano string can be used instead of a band. In addition, it is also possible to cover the greenhouse with a net, so that the divided fragments do not fall apart. Therefore, any of the above can function as a means of ligating the divided fragments.
[0135] Figures 17 and 18 show an example of a prefabricated greenhouse of expanded polystyrene to accommodate the hydroponic cultivation system of the present invention. Figure 17 is a perspective view showing the external appearance of a greenhouse accommodating a hydroponic cultivation system 1. Figure 18 is an exploded perspective view of the same. Hereinafter, left, right, front / back and back / back are defined as illustrated for convenience.
[0136] As shown in Figure 17, the hydroponic cultivation system 1 greenhouse has a semi-cylindrical W circumferential wall that is elongated in the anterior-posterior direction and anterior posterior 2000 walls with a shape of approximately half a disk to block the anterior surfaces and posterior of the circumferential wall W, as well as a space to accommodate a hydroponic cultivation system inside. As shown by Figure 17, the hydroponic cultivation system 1 greenhouse has an arched roof. Its totality is in the shape of a tunnel.
[0137] (Split fragments) The semi-cylindrical circumferential wall W as shown in 18 is assembled by joining several 1100 arched and divided circumferential walls. Each 1100 divided circumferential wall is made up of three divided fragments 1100a-1100c, which are connected while they are connected. in contact with each other in the axial longitudinal direction. Each of the divided circumferential walls is connected while contacting each other on each end surface in the axial longitudinal direction.
[0138] As used herein, "connect" refers to a certain element and another element being in contact and trapped. Here, adhesion with an adhesive is also connection and coupling of snap-on sections and snap-on attachment are also connections.
[0139] The anterior and posterior walls 2000 can be composed of a single divided fragment or formed with several divided fragments. Figure 18 shows a configuration in which the anterior and posterior walls are composed of a single divided fragment. Naturally, it is possible to join several divided fragments to assemble the anterior and posterior walls 2000. The circumferential walls and the anterior and posterior walls are accommodated in a 3000 foundation to be fixed. In the configuration of Figure 18, the foundations 3000 are arranged in two rows in the direction of the width of the hydroponic cultivation system 1 greenhouse to support the lower ends of the circumferential wall W. However, the foundation of the greenhouse of the hydroponic cultivation system 1 hydroponic cultivation the present invention is not limited to such a specific format or representation. Those with skill in the field are able to build an appropriate foundation.
[0140] The size of a single hydroponic cultivation accommodation greenhouse 1 can be appropriately determined by those skilled in the art depending on the size of the hydroponic cultivation system to be accommodated or the plant to be cultivated. For example, the width (length in the left-direct direction) is about 5-10 m, the depth (length in the front-back direction) is about 20-50 m, and the height is about 3-5 m.
[0141] The split fragments 1100a-1100c and 2100 are manufactured in advance in a factory and are assembled at the construction site. The size of the divided fragments 1100a-1100c and 2100 can be suitably determined by those skilled in the art considering the ease of transport or assembly. In a preferred configuration, where the split fragments 1100a-1100c and 2100 are made of expanded polystyrene foam, each divided fragment is lightweight in order to facilitate transportation and assembly operations. An opening 2200, which is an entrance / exit of stove 1, is formed in advance on the split fragment 2100. A door 2300 that can be opened or closed can be installed in opening 2200.
[0142] Figure 19 is an elevation view showing an assembled state of 1100 divided circumferential walls that are divided into three in the circumferential direction. Figure 20 is an expanded view of section IV in Figure 19. In one configuration, a convex section 1110 is formed on the upper end surface of the divided fragment 1100a and a concave section 1120 is formed on the opposite lower end surface of the divided fragment 1100b, as shown in Figure 20. The concave section 1120 is fitted with the convex section 1110 to connect the divided fragment 1100a with the divided fragment 1100b. In addition, the divided fragments 1100a and 1100b can be joined with adhesive and fixed to each other in that state. The divided fragment 1100b and the divided fragment 1100c are connected similarly.
[0143] Figure 21 (a) is a perspective view showing a united state configuration of the circumferential walls 1100 in the anterior and posterior direction. Figure 21 (b) is a cross-sectional view of a connecting section thereof (sectional view along line VI-VI in Figure 20). As shown in Figure 21, a reinforcement member can be interposed between two adjacent divided fragments 1100a, to reinforce the entire greenhouse. Such a reinforcing member can be any known member in the field that can be brought into the stove to reinforce it. The specific format can be determined by those skilled in the matter for assembly. In a configuration shown in Figure 21, an H 5000 beam is inserted, which is practically semicircular to match the shape of the stove. The lower end section of the H 5000 beam, for example, can be attached to the foundation 3000 entirely with the fragment divided 1100a by a penetration screw.
[0144] The concave sections 1130 and 1140 for fitting with the H 5000 beam are formed on each of the anterior-posterior end surfaces of each divided fragment 1100a, and the fragments 1100a are connected to each other by the H 5000 beam. The fragments split 1100b and split fragments 1100c can be similarly connected to each other by beam H 5000. beam 5000 thus functions as a reinforcing member for greenhouse 1, so that the strength of the entire greenhouse to accommodate a system hydroponic cultivation can be increased. As a result, this allows the joining of the circumferential walls divided 1100 to a length of several meters to mount the greenhouse 1, as well as the assembly of the greenhouse 1 in regions with significant snow, in terms of strength. In addition, when an H 5000 beam is interposed, the H 5000 beam must not be exposed to the surface. Thus, it is possible to prevent the H 5000 beam from rusting.
[0145] When there is no need for much resistance for greenhouse 1 (eg when there is no concern for snow), a 5100 board can be interposed to connect the 1100 split fragments to each other via the 5100 board instead of the beam H 5000 as shown in Figure 21 (c).
[0146] An example of an assembly sequence for the hydroponic system 1 accommodation greenhouse of the present invention is now explained. First, as shown in Figure 18, the foundation 3000 is placed where stove 1 is to be mounted. A reinforcement member (eg, beam H 5000) is then lifted in a position that corresponds to the frontmost section of stove 1, and each concave section 1140 of the front end of each split fragment 1100a-1100c is fitted with the beam H 5000. In this state, the lower end section of the H 5000 beam and the lower end section of the split fragments 1100a and 1100c are attached to the foundation 3000 with a penetration screw. At this point, the divided fragments 1100a-1100c are joined together in the circumferential direction by the concave section 1120 and the concave section 1110 to form the divided circumferential wall 1100. The H 5000 beam is then fitted with the concave section 1130 at the rear end of the wall split circumferential 1100, and the connection operation of the split circumferential wall 1100 by beam H 5000 is repeated until the entire stove has the predetermined length.
[0147] When the entire greenhouse has the predetermined length, a layer of foam is placed and the concrete floor is poured; and a coating or the like is applied as needed between the left and right foundations 3000. In addition, a reflective material can be applied to the inner surface of the stove 1, or a paint material can be applied to the outer surface of the stove 1. After a hydroponic cultivation system, necessary parts and products have been transported into greenhouse 1, the split fragments 2100 are joined to the circumferential walls divided 1100 in the front and rear end sections of greenhouse 1 by the H 5000 beam. The front surfaces and the back of greenhouse 1 are thus closed, in order to form a sealed and isolated space from the external area, and suitable for hydroponic cultivation. A reflective material or a painting material can be applied to the surface of the split fragments 1100a-1100c in advance in a factory.
[0148] The hydroponic cultivation system accommodation greenhouse of the present invention may comprise a wind-protected room, bathing room, changing room / antechamber, sterilization room, storeroom, cultivation room and the like, as needed.
[0149] In a preferred configuration, the entire internal surface of the hydroponic cultivation system 1 accommodation greenhouse has a curved shape from the bottom to the top, although it has a few uneven portions. Thus, it is possible to create a very hygienic internal space, where there is no tendency to accumulate dust or microorganisms.
[0150] (Split circumferential wall and split roof) In another configuration, the hydroponic cultivation system accommodation greenhouse of the present invention can be configured to comprise the circumferential wall 1100 and a split roof 1200 using expanded polystyrene foam as constitution material. Figure 22 shows a specific configuration of the hydroponic cultivation system 1 greenhouse consisting of divided circumferential walls 1100 and divided roofs 1200. In Figure 22, the divided circumferential wall 1100 has opposite divided circumferential walls, in the form of a flat plate, 1100a , 1100b and 1100c. The split roof 1200 has split roofs 1200a-1200c that each extend between opposite circumferential divided walls in a practically arched shape. That is, several divided circumferential walls and divided roofs are placed together in order to form a hydroponic cultivation system 1 greenhouse. When a larger number of divided circumferential walls and divided roofs are placed together, a large-scale greenhouse 1 can be placed. formed without using a larger individual fragment of expanded polystyrene foam.
[0151] As shown in Figure 22, each hitch section of the split circumferential wall 1100 and each hitch section of the split roof 1200 project outward, so that the thickness of the hitch sections is thicker than other portions. The contact area between the divided circumferential walls and the divided roofs is thus increased, to increase the resistance of the interlocking sections. Furthermore, with such a configuration, the interlocking sections would have a ribbed structure, so that it is possible to achieve greater resistance not only from the interlocking sections, but also from the entire stove 1. In Figure 22, ribs RB present a ribbed formation projecting upwards towards the internal space in the sections of the divided circumferential walls and the divided roof. However, the ribs can be provided facing outward, the specific shape of the ribs being any one, provided that it is possible to achieve better resistance of the interlocking sections and the entire stove. In addition, ribs may be provided in portions other than the interlocking sections of the circumferential walls and divided roofs.
[0152] In one configuration, the hydroponic cultivation system accommodation greenhouse of the present invention has an HS eave on the split roof 1200 as shown in Figure 23. Figure 23 (b) shows the state of a connecting surface between the circumferential wall split 1100 and the split roof 1200 having such an HS eave. A skylight TM skylight is provided on 23 (a) and 23 (b). However, such a skylight can be provided or not. In a preferred configuration, the thickness of the split roof varies, being at its maximum thickness in the HS eave portion, as shown in Figures 23 (a) and 23 (b). This serves to increase the strength in the HS eave portion. However, the shape of the split roof 1200 is not necessarily so limited. The end sections where the HS eave portion is provided do not necessarily have to be of the maximum thickness.
[0153] (Connection with other construction) The hydroponic cultivation system 1 accommodation greenhouse of the present invention can be used as an entire unit or by the conjunction of the greenhouse with another construction. For example, stove 1 having an arched roof can be used by joining it with another semi-spherical or semi-cylindrical construction. Figure 24 shows a configuration in which the hydroponic system 1 accommodation greenhouse is joined to another structure 1 'by means of a CN connection section. If stove 1 and structure 1 'are connected in such a way that the internal spaces are communicable via an internal path, spaces with different shapes can be readily formed. A CN link section can be provided, for example, with a door. Another 1 'structure can be a bathing room, dressing room, sterilization room, store or similar.
[0154] Figure 25 shows an expanded view of the CN connection section in a configuration of a union between the hydroponic cultivation system accommodation greenhouse 1 and a dome 1 'construction. In this specific example, an OP aperture and a convex section projecting outward to encircle the OP aperture are provided to split fragment 1100a of kiln 1. Similarly, an OP aperture and a convex section projecting outward to encircle the OP openings are provided to the split fragment 1100 'for construction 1'. The surfaces of the ends of the convex sections are connected to each other, so that the internal space of stove 1 and the internal space of building 1 'have communication. The specifics are set out below.
[0155] The CN connection section is provided with the port described above PT. The divided circumferential wall 1100a of greenhouse 1 facing the PT door is conically shaped and curved towards the PT door. In addition, the OP opening with approximately the same open area as the PT door is provided. The end surface of the divided circumferential wall 1100a abuts the end surface of the divided circumferential wall 1100'a forming the PT door of construction 1 ', where they are connected without space. In addition, stove 1 and building 1 'are also connected without space above and below the PT door. The stove 1 and the construction 1 'are thus connected by the connection section CN and a PA path is formed by the PT port and the OP opening within the connection section CN. As a result, greenhouse 1 and construction 1 'are communicable with each other via the PA path. A highly extensible greenhouse with different types of constructions can be readily formed by joining greenhouse 1 and construction 1 'in this way. In addition, the CN connection section can increase the resistance of the greenhouse itself. In addition, a connecting member in the connection between stove 1 and construction 1 'becomes unnecessary, so that the number of parts can be reduced and construction is facilitated. Also, as the constructions can be connected only by connecting the end surfaces of the concave sections that surround an opening provided to oppose them, construction is facilitated.
[0156] (Connecting the structures without using a connecting section) When the CN connecting section is used as reported above to provide several arched greenhouses in the direction from left to right, the presence of several CN connecting sections joining the greenhouses in the direction left-right can create multiple arched greenhouses with an arched roof without using the CN connection section described above.
[0157] In this regard, in a configuration of the present invention, a hydroponic cultivation system accommodation greenhouse is an arched building, comprising a first structure that has a first arched roof and a second structure that has a second roof in arc, in which the first structure and the second structure can have a configuration that shares at least a portion of a dividing wall dividing the first structure and the second structure. That is, structures with an arched roof are connected without using the CN connection section.
[0158] Specifically, the first arched roof comprises a divided fragment of the first arched roof, the second arched roof comprises a divided fragment of the second arched roof, and the dividing wall comprises a divided fragment of a leg section of the dividing wall, wherein the divided fragment of the first arched roof, and the divided fragment of the second arched roof, and the divided fragment of the leg section of the dividing wall are connected through a divided fragment of an upper section of the dividing wall, such that the first structure and the second structure share at least a portion of the partition wall.
[0159] Such a greenhouse further comprises a third structure that has a third arched roof, and the second structure and the third structure share at least a portion of a dividing wall that divides the second structure and the third structure so that the structures can be joined in succession without using the CN connection section.
[0160] The following are specific explanations. Figure 26 (a) is an overview of a hydroponic cultivation system accommodation greenhouse 1 combining three arched structures 1α, 1 β, and 1Y. The arcuate structures 1α and 1β share a partition wall 8, and the arcuate structures 1β and 1Y share another partition wall 8 '. The size of oven 1 can be appropriately determined by those skilled in the art in accordance with the application. However, as an example, a fragment divided with an external shell radius R of 3850 mm is used to connect 10 divided fragments in the anterior-posterior direction in Figure 26 (a). In this case, the width in the left-right direction is about 19 m and the width in the anterior-posterior direction is about 20 m. The height from the ground surface to the inner ceiling is 3650 mm. When a fragment divided with an outer shell radius R of 4850 mm is used to connect 13 fragments divided in the anterior-posterior direction, the width in the left-right direction is about 26 m and the width in the anterior-posterior direction is about 26 m . The height from the ground surface to the interior ceiling is 4650 mm. In this way, an extensive space with lengths in the left-right and front-rear direction can be formed inside greenhouse 1. Although not shown in Figure 26, a wall or a door can be provided at the front end and at the rear end in the front direction. - later.
[0161] Figure 26 (b) is a cross-sectional view of greenhouse 1 in Figure 26 (a). As shown in Figure 26 (b), stove 1 can be assembled from divided fragments 5 of a side wall provided at the left most end and at the right most end, a divided fragment 6 of an arched roof, a divided fragment 7 of the upper section of the partition wall, and a fragment fragment 8 of the leg section of the partition wall installed in the lower section of the divided fragment 7 of an upper section of the partition wall. For example, such a configuration can extend an arched roof in the left-right direction. However, divided fragments of a sidewall and divided fragment of an arched roof can be a single divided fragment or two or more divided fragments. In addition, a divided fragment of an upper section of the dividing wall may or may not be provided. Any split fragment can be used for assembly, as long as structures with an arched roof are tied together and adjacent structures share a dividing wall.
[0162] When there are structures with, for example, external R radii of 3850 mmm and 4850 mm, divided fragments 5 of a side wall, divided fragments 6 of an arched roof, fragment fragments 7 of an upper section of partition wall, and fragments split 8 of a partition wall leg section with two corresponding different dimensions can be prepared. It is desirable that the external shell radius R is 3.5-5.0 m.
[0163] Figure 27 is a perspective view of each divided fragment that constitutes the hydroponic cultivation system 1 of Figure 26. (A) is a perspective view of the divided fragment 5 of a side wall, (B) is a view in perspective of the divided fragment 6 of an arched roof, (C) is a perspective view of the divided fragment 7 of an upper partition wall section and (D) is a perspective view of the divided fragment 8 of the partition wall leg section . For the split fragment 5 of a side wall, an anterior connection section 5a, an upper connection section 5b, and a posterior connection section 5c are connected to other divided fragments. A 5d leg contacts the soil surface or the foundation. The split fragment 6 of an arched roof is an arched roof in the left-right direction. An anterior connection section 6a, a left connection section 6b, a posterior connection section 6c, and a right connection section 6d are connected to other divided fragments. For the split fragment 7 of an upper dividing wall section, an anterior connecting section 7a, a left connecting section 7b, a posterior connecting section 7c, a right connecting section 7d, and a lower connecting section 7e are connected to other divided fragments. The divided fragment 8 of the leg section of the partition wall has a leg that supports the lower section of the divided fragment 76 of the upper section of the partition wall. A hollow hole 9 can be provided in that leg. Leg 8d contacts the ground surface of the foundation. For the split fragment 8 of the leg section of the dividing wall, an anterior connection section 8a, an upper connection section 8b, and a posterior connection section 8c are connected to other divided fragments. The same split fragment 5 of a side wall can be used for one end and the other end in the left-right direction of greenhouse 1. Although Figure 27 shows only the split fragment 5 of a side wall at one end, the split fragment 5 of a side wall at the other end has a shape in which the front connection section 5a and the rear connection section 5c of the divided fragment 5 of a side wall shown in Figure 27 (A) are exchanged.
[0164] The divided fragment 7 of the upper part of the partition wall can be integrally formed with the divided fragment 8 of a leg section of the partition wall. In that case, the construction for connecting the lower connecting section 7e of the divided fragment 7 of the upper dividing wall section 8b of the divided fragment 8 of a dividing wall leg section can be omitted. In addition, when the dimension of the divided fragment 7 of an upper section of the dividing wall is large in the left-right direction, for example, the left wing or the right wing can be separated, with two divided fragments being composed.
[0165] Figure 28 is a cross-sectional view when the hydroponic cultivation system accommodation greenhouse 1 according to the present invention is installed on a sloping surface. In this configuration, the divided fragment 8 of the leg section of the dividing wall is not perpendicular with respect to the inclination, but perpendicular with respect to the horizontal direction. For this reason, as shown in the expanded bubble C1, the left wing 7lw is folded further down and the right wing 7rw is further folded up to the divided fragment 7 of the upper dividing wall section for an inclination compared to the divided fragment 7 from a top section of partition wall to a standard horizontal floor. The bend angle is determined based on the slope of the ground. In addition, the height h1 of the left wing 7lw is lower than the height h2 of the right wing 7rw. The hydroponic cultivation system accommodation greenhouse 1 can be installed on an inclined surface using such a divided fragment 7 from an upper section of a partition wall. The split fragment 7 for the upper dividing wall section for a sloping surface is the opposite of the divided fragment 7 for the upper dividing wall section for a sloping surface. If the inclination angles are the same, the same divided fragment 7 of the upper section of the dividing wall can be used.
[0166] Figure 29 is a diagram of a configuration in which the divided fragment 7 of the upper section of a partition wall is rotatable with respect to the divided fragment 8 of the leg section of a partition wall. A roller 7f is provided in the lower connecting section 7e of the divided fragment 7 of the upper section of a partition wall, and a concave semi-cylindrical section 8e is provided in the upper connecting section 8b of the divided fragment 8 of the leg section of a partition wall. As shown in expanded bubble C1, stove 1 can be installed on a horizontal soil surface by connecting the divided fragment 7 of the upper section of a dividing wall horizontally to the divided fragment 8 of a leg section. As shown in expanded bubble C2, stove 1 can be installed on a sloping surface by connecting the divided fragment 7 of an upper section of the partition wall to the divided fragment 8 of a leg section of the partition wall with the right side inclined to up. As shown in expanded bubble C3, a prefabricated building can be installed on a sloping surface by connecting the divided fragment 7 of an upper section of the partition wall to the divided fragment 8 of a leg section of the partition wall with the right side tilted down.
[0167] Figure 30 is a diagram of a configuration in which a left wing and a right wing of the divided fragment 7 of an upper section of the divided wall are individually rotatable with respect to the divided fragment 8 of a leg section of the wall. divider. The left wing and the right wing are integrally formed and are not able to move separately in the divided fragment of the upper section of the dividing wall in Figure 29. However, the left wing and the ring are formed separately so that they are able to move independently in the split fragment of an upper portion of the partition wall with the configuration shown in Figure 30. Rollers 7f and 7f 'are provided alternately in the axial direction in the lower connection section of the left wing 7lw and right wing 7rw. In addition, a semi-cylindrical concave section 8e for receiving rollers 7f and 7f 'is provided in the upper connecting section of the divided fragment 8 of a leg section. According to such a configuration, the left wing 7lw and the right wing 7rw can be connected in order to allow individual rotation. As shown in the expanded bubble C1, a prefabricated building can be installed on a horizontal ground surface by connecting the left wing 7lw and the right wing 7rw horizontally to the split fragment 8 of a leg section of the partition wall. As shown in expanded bubble C2, a prefabricated building can also be installed on a downward sloping surface in the right direction from the horizontal line by connecting the left wing 7lw horizontally to the split fragment 8 of a partition wall leg section and connecting the right wing 7rw to the split fragment 8 of the leg section with the right side angled downwards. As shown in the expanded bubble C3, a hydroponic cultivation system accommodation greenhouse can also be installed on an upward sloping surface on the right side with respect to the horizontal line connecting the left wing 7lw horizontally to the divided fragment 8 of a section of leg and connecting the right wing 7rw to the divided fragment 8 of a leg section with the right side tilted upwards. In this way, a hydroponic cultivation system accommodation greenhouse can be installed on a soil surface that changes from valley to mountain and mountain to valley in order to correspond to that surface.
[0168] (Hydroponic cultivation system accommodation greenhouse and foundation) In a representative configuration, the hydroponic cultivation system accommodation greenhouse is affixed to a foundation (for example, see foundation 3000 in Figure 18).
[0169] Figure 31 is a diagram showing the detailed assembled structure of the 1100 divided fragment. A PD foundation is placed in a location where a greenhouse is installed. The PD foundation, as illustrated, has a support section for the OM greenhouse to support a split fragment at the same height as the GL soil surface and the press sections of the split fragment DS. A FL floor surface is also formed on the PD foundation at a predetermined height (eg, 360 mm) from the GL floor surface. A split fragment of a greenhouse has, at the base end section, a protrusion section DB, which fits with the pressing section DS to ensure a fixed position of the greenhouse and restrict the upward and downward movement of the greenhouse in the radial direction. internal. The specific shape of the protruding section DB and the pressing sections DS can be any one as long as they fit together to prevent the stove from moving in an internal radial direction. In addition, the DB protrusion section of a divided fragment is in the section of the base end of the greenhouse. However, a "base end section" does not necessarily have to be the end section of the present invention, it refers to a position in the vicinity of a base section of a greenhouse where it can be fitted into the DS press section for prevent the stove from moving upwards or downwards in the internal radial direction. The specific shapes and positions of the protruding section DB and the pressing section DS can be appropriately determined by those skilled in the art. In the configuration shown in Figure 31, the pressing section of the divided fragment DS is a concave ring-shaped section. An L B-shaped base section provided in the base end section of each divided fragment 1100 is locked with the pressing section of the DS dome to ensure the fixed position of the stove and restrict its upward movement or towards the inner radial section. A restriction section SM to prevent the expansion of the greenhouse in the external radial direction can be provided along the entire ring-shaped circumference along the outer circumference section of the protrusion section DB of the divided fragment.
[0170] (Transportable Mounting Foundation) In a configuration of the present invention, the foundation is a transportable mounting foundation. There is generally no intention of transporting a laid foundation. A configuration of a transportable mounting foundation is shown in Figure 32. Figure 32 (a) is a perspective view of a movable mounting foundation. In this configuration, the 3000 foundation is composed of a series of divided substrates 3100. A floor to form a flat surface, which is a floor surface of the greenhouse, can be laid on the substrate 3100. As shown in Figure 32, the establishment of a mobile transportable assembly foundation and a prefabricated greenhouse can be realized not only by building a greenhouse from divided fragments, but also by building the foundation to be made by joining a series of divided substrates. The foundation is made in a toroidal shape to facilitate understanding in Figure 32. However, the shape is not limited to this one. The shape of a foundation can be determined to match the shape of the greenhouse erected on it.
[0171] Figure 32 (b) showing a configuration of a split substrate 3100. As a toroidal foundation was shown in Figure 32 (a), the split substrate 3100 in Figure 32 (b) also has an arc shape. However, the shape of the split substrate 3100 can be changed according to the shape of the foundation 3000.
[0172] In Figure 32 (b), a step section 3300 to accommodate a floor formed along the circumference on the circumferential side of the divided substrate 3100. Upper and lower protruding sections 3400A and 3400B projecting towards the outer substrate are formed along the circumference, and a 3500 depression used as an engagement section between the lower upper protrusion sections 3400A and 3400B is formed on the outer circumferential side of the divided substrate 3100. Therefore, the step section 3300 is formed along the entire circumference on the inner circumferential side of the upper section of the foundation 3000, which is constituted by placing the 3100 split substrates. In addition, the concave locking section 3500 is formed along the entire circumference on the circumferential side of the upper section. The 3500 depression serves the function of the DS pressing section in Figure 31.
[0173] In the configuration shown in Figure 32 (b), a pair of guide pins 3600 for positioning are embedded within the surface of one end in the longitudinal direction of each divided substrate 3100, and a pair of holes for guide pin ( not shown) is done on the surface of the other end. However, it is not necessary to use such a guide pin configuration. Any means that can fit split substrates 3100 together can be used to fit adjacent split substrates. Adjacent split substrates are connected between by inserting the guide pins 3600 into the holes for the guide pin in order to assemble the base 3000.
[0174] In a preferred configuration, external circumferential surfaces of a connection section of two adjacent divided substrates 3110 are joined via a connection plate 36. The connection plate 36 shown in Figure 32 (b) can be used to join substrates divided as well as to join the divided fragment 1100 of the hydroponic cultivation system accommodation greenhouse 1 to the foundation 3000 by means, for example, of a screw.
[0175] As shown in Figure 32 (b), a 3700 insert is embedded within the top surface of a divided substrate, which can be used for suspension or construction.
[0176] The 3100 split substrates are attached to each other on the ground to form the 3000 foundation. A floor can be provided inside. In a preferred configuration, crushed stones or the like can be placed to a predetermined depth inside the 3000 foundation. Polyethylene or another resin film is placed on top. In addition, the concrete is filled up to the height of the surface 3000. A smooth finish is applied on the concrete surface to form a floor. The mobile mounting foundation 3000 is completed by the steps described above.
[0177] The hydroponic cultivation system accommodation greenhouse 1 is installed on the mobile mounting foundation 3000 built in this way by assembling the 1100 divided fragments. That is, the protrusion section DB of the section on the base side of a fragment split is fitted into the depression 3500 while connecting the split fragments 1100 to each other to assemble the stove 1. In a preferred configuration, the base section of the split fragment 1100 can be attached or fixed to the substrate 3100 by the connection plate 36. That is, the fragment 1100 is locked in the foundation 3000 by the connection plate 36. The external circumferential surface of a mounted dome can be covered with concrete mortar, resin or similar for water resistance, fire resistance, weather resistance etc. .
[0178] In this configuration, the split substrates 3100 are mounted as the foundation 3000 by the connection plate 36 to install a floor on the foundation 3000. Therefore, the foundation 3000 can be promptly dismantled by loosening the screw of the connection plate 36 For this reason, the foundation and the greenhouse can be readily moved and installed elsewhere. In addition, the foundation of the locking section 3500 for the protruding section DB of the divided fragment 1100 is integrally formed with the outer circumferential surface of the divided substrate 3100 that constitutes the foundation. Therefore, the structure of the 3000 foundation can be simplified. In addition, the base section DB is configured to be attached to the connection plate 36 to join the split substrates 3100. Thus, the configuration of the foundation can be simplified to facilitate construction.
[0179] In the configuration described above, the floor formed inside the 3000 foundation can be formed by placing a crosspiece, such as a steel plate through the step section 3300 on the inner circumferential side of the 3000 foundation to place floor plates instead of concrete or crushed stones as described above. It is preferable that each steel plate beam has a length that considers its transportability and can be screwed and disassembled, and that the floor size also considers the transportability can be screwed to the beam and dismounted. That is, it is preferable that the floor is also divisible and transportable. In doing so, the foundation 3000 can be disassembled by relieving the fastening of the connection plate 36. Thus, the disassembly property of the foundation 3000 is improved in such a way that the base can be quickly removed and installed.
[0180] (Reinforcement of the hydroponic cultivation system accommodation greenhouse) The hydroponic cultivation system accommodation greenhouse of the present invention is preferably reinforced by several methods.
[0181] For example, a reinforcement member can be integrated within a divided fragment. The material and shape of a reinforcement member can be appropriately determined by those skilled in the art depending on the shape and application of the stove. Figure 33 shows a preferred embodiment of incorporating a reinforcement member within a divided fragment.
[0182] As shown in Figure 33, a reinforcement member 4000 (eg, steel frame) is placed inside metallic molds G1 and G2 for molding foam from a divided fragment. At that time, it is preferable to adjust the male part G2 after adjusting the reinforcement member 4000 to the female part G1. In the configuration of Figure 33, the female part G1 has approximately the same shape as the outer circumferential surface of the reinforcement member 4000, which is adjusted by touching the female part G1. A gap is created between the reinforcement member 4000 and the metal mold G2.
[0183] The raw material grains (pre-foamed) are then included between the female part G1 and the male part G2. High pressure steam is blown through a heating port G1a (seen in section c-c) provided in the G1 female to heat the beans. The high pressure steam inside the G1 and G2 molds comes out through a small orifice (not shown) provided in the male G2. The grains thus break within the G1 and G2 molds in such a way that the expanded polystyrene foam is made by molding along the shape of the surface of the G1 and G2 molds. At that time, expanded polystyrene foam 4300 goes to the back of reinforcement member 4000 covering the surroundings of reinforcement member 4000, as shown in the cc section view of Figure 33. Therefore, expanded polystyrene foam 4300 adheres well and becomes entangled with reinforcement member 4000 showing strong adhesion. At that time, a heating orifice 40a penetrating the reinforcement member 4000 is provided to blow steam directly into the back side of the reinforcement member 4000, that is, next to the male part G2, such that the foam is produced in the rear side of reinforcement member 4000 in the initial stage to further increase the adhesion between expanded polystyrene foam and reinforcement member 4000. Thus, in a preferred embodiment of the present invention, a reinforcement member comprises a hollow hole for passing steam into .
[0184] The steam is then stopped for sufficient cooling. The G1 and G2 molds are then detached to remove the molded product, a divided fragment. In a divided fragment formed in this way, the reinforcement member 4000 is positioned outside the divided fragment. The outer circumferential surface of reinforcement member 4000 and the outer circumferential surface of the expanded polystyrene foam 4300 are formed without height difference. That is, a surface of the reinforcement member 4000 is exposed along the meridian of the dome. Paint can be placed on the surface of the molded split fragment for blocking ultraviolet rays and water resistance.
[0185] In a preferred configuration, the reinforcement member 4000 has a clamping member for securing a fragment divided into another fragment divided. Such a configuration readily fulfills the firm fixation of a divided fragment with another divided fragment. For example, after molding a split fragment as described above, a clamping member (e.g., screw and slot) can be fabricated on part of the reinforcement member 4000 from the outer portion of the split fragment.
[0186] The steps above are performed in a factory. After the manufacture of several divided fragments, the fragments are transported to a construction site for the assembly of the greenhouse to accommodate the hydroponic cultivation system 1.
[0187] (Reinforcement per sheet and application layer) Figure 34 shows a specific reinforcement configuration with a sheet and base material. In this reinforcement configuration with sheet and base material, sheets MS, MSa, and MSb are applied to cover a portion that connects adjacent divided fragments 1100, a portion that rises out from the foundation 3000 of the divided fragments, and a a corresponding portion of a foundation and an application layer (eg, base material) is applied to a portion that includes the sheet being assembled, such that two divided fragments and the fragment divided with the foundation can be firmly fixed.
[0188] The sheet used in this configuration can be any sheet that is able to stabilize the fixation of a base with a fragment divided by being applied as described above. The sheet is preferably a mesh sheet and, more preferably, a mesh sheet formed with inorganic fiber. Inorganic fibers refer to carbon fiber, glass fiber, metal fiber and the like. The sheet may be a sheet consisting of resin-based fiber with tensile strength. The sheet is preferably in woven form in a net-like state. For example, the use of carbon fiber with a thickness of 0.3-1 mm and 6 meshes (6 holes per inch mesh) can give the effect. A sheet of mesh greater than 12 meshes is too thin and is more difficult to operate, although the mesh is too thick with 6 meshes or less. Strength or resistance of a sheet (e.g., mesh sheet), in addition to bonding by adhesive or the like, thus acts on the bonding portion of the divided fragment 1100 in oven 1, so that the divided fragments can be strongly bonded.
[0189] In one configuration, a mesh sheet MS is applied to a connecting portion of adjacent divided fragments 1100. In addition, as shown in Figure 34 (a), the mesh sheet MSa can be applied to a connecting portion between the outer surface of the split fragment 1100 and the foundation 3000. Also, as shown in Figure 34 (b), the mesh sheet MSb can be applied in a connection portion between the inner surface of the split fragment 1100 and the foundation 3000. That is, the mesh sheets MSa and MSb can be applied on the outer circumferential side and on the inner circumferential side of the hydroponic cultivation system 1 greenhouse of the present invention.
[0190] In the rear end section of kiln 1 on the outer surface side, the mesh sheet MSa is applied to the corresponding portion of the foundation 3000 as shown in Figure 34 (a). The mesh sheet MSa successively covers the outer circumferential side of the lower end of stove 1 and is successively applied on the base 3000 and adjacent divided fragments 1100 aligned side by side. The same applies to the side of the inner surface of kiln 1. As shown in Figure 34 (b), the mesh sheet MSb is successively applied over the lower end section of the inner surface of the split fragment 1100 and the corresponding position of the foundation 3000 that corresponds to it. A DS leg section extending to the lower side is integrally formed in the lower end section of the inner surface of the divided fragment 1100. The MSb mesh sheet is applied from the DS leg sections to the corresponding portion of the 3000 foundation. a preferred configuration, a base material is further applied to the inner surface and the outer surface of stove 1. As such application hides the mesh sheets MS, MSa, and MSb, this prevents deterioration of the external appearance.
[0191] The bond strength between oven 1 and the foundation 3000 is increased by covering the portion that connects the divided fragments 1100, the portion that rises from the foundation 3000 of the divided fragments 1100, and the portion of the foundation 3000 that corresponds to it with the MS, MSa and MSb network sheets in this way. Thus, stove 1 can be stably raised on the 3000 foundation.
[0192] An acrylic resin such as polyacrylic acid ester or polymethacrylic acid ester is used as an adhesive for adhesion between divided fragments. Preferably, mortar powder can be mixed and dispersed in such an acrylic resin. Acrylic resins have great adhesive strength against expanded polystyrene foam. Thus, an acrylic resin can strongly bond divided fragments made of expanded polystyrene foam.
[0193] As an adhesive would have toughness with elasticity using an acrylic resin mixed with mortar powder as an adhesive for split fragments, it would be possible to obtain a stove with excellent resistance to earthquakes or resistance to impact. For this reason, earthquake, agitation or impact would not cause the connecting portion of greenhouse 1 to crack. In addition, as such an adhesive is water resistant, rain infiltration from the connecting portion can be avoided for an extended period.
[0194] A base material is generally applied to the entire inner surface and outer surface of kiln 1 to a predetermined thickness after the application of a sheet. As a base material, resin coated with fiber such as fiberglass or carbon fiber and mortar powders dispersed within it can be used. As a resin coating, an acrylic resin such as polymethacrylic acid ester or polyacrylic acid ester or other resins can be used. The ingredients and thickness of the base material can be appropriately determined by those skilled in the art. As an example, the thickness of a base material can be a predetermined thickness in the range of 1-3 cm.
[0195] After applying a base material, it is common to apply paint for external finishing to the surface of the base material on the external surface of stove 1 and to apply paint for internal finishing to the base material on the internal surface. Any paint known in the art can be used as an exterior finish paint. However, water-repellent and UV-blocking paint is preferred. Modified silicone resin paint or other resin paint can be selected as having such properties. Any paint that can form an internal space for hydroponic cultivation can be used as paint for the interior lining, but for example, paint of natural origin similar to clay is preferred. Diatomaceous earth or plaster can be selected as a paint similar to clay of natural origin. Diatomaceous earth is heat resistant and safe, as it does not burn even when in contact with a moderate level of fire from a cigarette or similar. Diatomaceous earth 18 has an absorption and formaldehyde removal action. Thus, the formaldehyde generated by a certain action of the modified silicone resin paint 17, which is a paint for external coating, or the base material 13, can be prevented from remaining in the environment. In addition, as diatomaceous earth absorbs and removes harmful substances, diatomaceous earth is safe and has a deodorizing action, as well as action to prevent outbreaks of ticks and mold.
[0196] (Improved adhesion between foamed resin and reinforcement member) Figure 35 (a) shows a specific configuration that can improve adhesion between the foamed resin and the reinforcement member in a divided fragment. In this configuration, the reinforcement member of the divided fragment comprises a network that extends in the longitudinal direction, a first flange that protrudes outward from the network in the transverse directions, and a second flange that protrudes outwardly from the network in the opposite direction of the first flange. The use of such a reinforcing member allows the resin to foam evenly and a more uniform molding of the divided fragment than in comparison to the reinforcing member with a U-shaped cross-section. For a reinforcing member with a U-shaped cross-section , a space remains in a portion around the interior of the U-shape when the crude foamed resin material is foamed and expanded by steam, so that the resin tends to foam without uniformity. As a reinforcement member in this configuration, steel in the form of + or Z can be used. Figure 35 shows a specific configuration of a fragment divided using steel in the form of Z as an example. As shown in Figure 35 (a), reinforcement member 4000 comprises a net 4100 extending in the longitudinal direction, a first flange 4200 projecting outward from net 4100 in one of the transverse directions, and a second flange 4300 projecting outwardly in the opposite direction to that of the first flange 4200. Figure 35 (a) illustrates a Z-shaped reinforcement member. However, the flange does not necessarily need to project outwardly from the top end or the bottom end of a network. Flanges can project outward in opposite directions anywhere in the network. Reinforcement members 4000 are typically arranged spaced in the transverse direction such that the 4100 net is perpendicular. Reinforcement member 4000 can be configured to be lightweight by providing a plurality of holes in the 4100 mesh or using a lightweight material such as aluminum.
[0197] Figure 35 (b) shows a configuration of a reinforcement member comprising a crossing member installed to intersect it. Cross member 4400 is installed to intersect reinforcement member 4000. A cross member and reinforcement member can be installed by any technique known in the art, such as welds or screws. The specific angle is not limited, as long as the reinforcement member and the cross member support and reinforce each other, but preferably the cross member and the reinforcement member are orthogonal. A structure consisting of reinforcement member 4000 crossing member 4400 is placed within a mold and the structure is installed to float from the bottom of the mold. Grains, raw material of the 1100 divided fragment, are placed in the mold and foamed and expanded with high temperature steam. The split fragment of foamed resin 1100 is formed by such integral molding. The divided fragments 1100 are shown with dotted lines in Figure 35 (b). The split fragment 1100 can be produced to own, by adjusting the rate of expansion. The compressive strength is 40 kN / m2 - 120 kN / m2. Therefore, the split fragment 1100 is capable of withstanding a large load. The bending force is 40 kN / m2 - 120 kN / m2. Thus, the divided fragment 1100 is capable of resisting folds. The fragment 1100 divided in this way is light, water resistant and readily processed.
[0198] Figure 35 (c) is a plan view of a divided fragment comprising a reinforcement member and a crossing member. The divided fragment 1100 has a rectangular shape with the reinforcement member 4000 and the crossing member 4400 incorporated internally. Reinforcement member 4000 and crossing member 4400 lie within the foamed resin and are therefore represented by the dotted lines. The dimension of the 1100 divided fragment can be appropriately determined by those skilled in the matter considering the size, transportability and constructability of the hydroponic cultivation system accommodation greenhouse. However, the dimension is about 5 m in the longitudinal direction and about 2 m in the transverse direction. Both the front and rear surfaces in the transverse direction can be provided with a concave section and a convex section, respectively. The concave section and the convex section are provided to extend in the longitudinal direction and are shaped to fit together. For example, the concave section of the divided fragment 1100 can be fitted with the convex section of another divided fragment to extend the divided fragment in the transverse direction. In other words, the concave section and the convex section function as a connection section to extend the divided fragment 1100 in the transverse direction. The cross member 4400 can be of any material with any shape that can intersect the reinforcement member for reinforcement. However, the crossing member 4400 is typically a flat, panel-shaped panel material. Figure 35 (c) shows a state in which the crossing members 4400 are installed at intervals of 1 m in the longitudinal direction of the divided fragment 1100 which is about 5 m in the longitudinal direction and about 2 m in the transverse direction.
[0199] (Hydroponic cultivation system accommodation greenhouse with two floors) The hydroponic cultivation system accommodation greenhouse 1 may comprise a plurality of support columns erected on at least a portion of a floor surface region in the greenhouse 1 and an upper floor surface supported by the support columns. In other words, the greenhouse can have two floors. Figure 36 shows a two-story hydroponic cultivation system accommodation greenhouse. In the configuration of Figure 36, the floor surface 201 of the first floor portion is formed to be lower than the floor surface 201 'next to the entrance 53. A plurality of columns 203 are erected on the floor surface 201 and a second surface the top floor 202 is formed above the columns. As illustrated, a spiral staircase or the like can be provided from the floor surface 201 'to the floor surface 202. In addition, stairs from the floor surface 201' to the floor surface 201 can be provided. floor 201 is formed to be lower than the floor surface 201 'in Figure 36. However, the floor surface 201 and the floor surface 201' can be on the same plane. In addition, the floor surface 201 can be formed higher than the floor surface 201 '. However, it is preferable that the floor surface 201 is formed lower than the floor surface 201 'because in this way, a wide space is ensured on the floor surface 202.
[0200] In a preferred configuration, the internal structure composed of the upper floor surface 202 and the columns 203 supporting it are separated from the external structure of greenhouse 1 by assembling divided fragments. The internal structure and the external structure are not structures in which one supports the other nor are they linked. Simplifying the greenhouse structure in this way facilitates assembly, thus allowing it to be assembled in a short period.
[0201] (Plate processed on the surface of the greenhouse) In another configuration, the hydroponic cultivation system accommodation greenhouse 1 may comprise a processed product for reinforcement and design. The processed product can be any one since it is made of foamed resin. However, the processed product is preferably formed with the same foamed resin as the foamed resin that constitutes stove 1. This is due to the fact that because, when the materials for the stove and the processed plate are of the same foamed resin, it is possible prevent the processed plate from peeling from the stove due to thermal contraction. In addition, a processed slab made of foamed resin is lighter compared to conventional or similar stone imitation slabs. Therefore, a processed slab made of foamed resin facilitates construction and is also preferable in terms of the overall robustness of the greenhouse. In a preferred configuration, a processed slab has a convex section on the surface of contact with the stove under adhesion. Peeling is prevented by such a convex section. The plate processed in this configuration can have a thin connection section on at least a portion of the outer surface. Such processed plate can be manufactured by molding, with a plurality of processed plates being connected through thin connection sections and then cutting into said connection sections. Therefore, a thin connection section is formed thin for cutting. As a thin connection section tends to be hard when molding foam with foamed resin, the foamed resin in the thin connection section can be made not so hard by two foam phases, consisting of pre-foam and foam molding.
[0202] (Seismic-based insulation structure) In another embodiment, the hydroponic cultivation system accommodation oven 1 of the present invention may comprise a seismic-based insulation structure. Figure 37 shows a seismic-based insulation structure of the hydroponic cultivation system accommodation greenhouse of the present invention. According to the seismic-based insulation structure shown in Figure 37, a sphere can absorb lateral vibration from an earthquake by dampening the agitation of the greenhouse by an improved soil foundation covered with uniform spheres. In addition, even if the improved soil foundation moves left or right, the stove barely moves, as it slides between its floor plate and the improved soil foundation. In addition, the subfloor, the side wall and the ceiling can all be formed of foamed resin to form a closed shell-like structure, so that the impact of an earthquake is dissipated by the entire greenhouse with appropriate damping to the individuals or materials existing in the stove.
[0203] Figure 37 is a cross-sectional view of the hydroponic cultivation system 1 of the present invention. Kiln 1 composed of foamed resin (eg expanded polystyrene foam) in divided fragments is placed on the improved GR soil foundation composed of ST spheres. In this configuration, stove 1 is in a closed structure in which the subfloor, the side wall and the ceiling surround the enclosure. A BP floor plate is provided in the lower section in contact with the improved GR soil foundation. The outer sections of the divided fragment 1100 constituting greenhouse 1 can be covered with a layer of tempered mortar MR about 2 cm thick. The MR hardened mortar layer can be mixed with an acrylic resin based adhesive such as polyacrylic acid ester or polymethacrylic acid ester to improve adhesion with foamed resin (eg expanded polystyrene foam) and to prevent breakage due to impact or vulnerability to impact by mixing carbon fiber with mortar.
[0204] The floor plate BP can be configured in such a way that the improved GR soil foundation and greenhouse 1 can slide. For example, plywood can be used for concrete molding. Plywood is used for concrete molding in a thickness of about 6-9 mm. The material of the BP floor plate is not limited to this. The BP floor plate can also be made of resin. In general, a layer of concrete is provided above the FL subfloor, and a floor is provided over it. The bottom side of the floor can also have a space for placing wiring or piping.
[0205] A hole about 50 cm deep is made in the soil of the area that covers the outer circumference of greenhouse 1, where the ST spheres are placed to form the improved soil foundation. ST spheres are typically placed in this hole to form the improved GR foundation. ST spheres can be of any material and shape as long as they effectively absorb earthquake vibrations. The ST balls are arranged in such a way that the stove can be placed on them with the possibility of sliding. The ST spheres are preferably parallelepiped with a diameter of about 15-30 cm and, more preferably, uniform cobblestones. Hard rubber balls, with appropriate hardness and elasticity, can also be used as ST balls that form the improved GR soil base. The diameter is preferably about 10-30 cm.
[0206] (Other configurations) As described above, the present invention has been illustrated by showing preferred configurations to facilitate understanding. The present invention is described below based on Examples. The explanation provided above and the following examples are not intended to limit the present invention, having the sole purpose of exemplifying. Therefore, the scope of the present invention should not be limited to the examples specifically described, but only the scope of the claims. [Industrial Applicability]
[0207] The present invention can be used in vegetable production as it provides a system capable of efficient hydroponic cultivation in a small space. The hydroponic cultivation system of the present invention is characterized by the small amount of culture solution. Therefore, such a system can be used to produce plants in desert regions where water is especially scarce. In addition, a large amount of vegetables can be produced even in environments that are not suitable for plant cultivation by combining such a hydroponic cultivation system with an expanded polystyrene foam greenhouse that has a high level of thermal insulation effect.
