    Floating trough for growing crops on water, as well as an assembly of such a drifting trough and a holder
    The invention relates to a float for growing crops on water. The drift boxes according to the invention are particularly adapted to be used in a basin of a cultivation system.
    The invention furthermore relates to an assembly of such a drifting trough and a holder for growing crops, as well as to such a holder.
    Growing systems for growing on water in a basin are generally known. It is also generally known herein to use drift trays in the basin, which have a rectangular shape and with cultivation locations therein, which form passages for providing access to water in the basin for roots of the crops. Such drifting trays are known, for example, from WO-2010/093248, and such drifting trays are more particularly in the general shape, which is comparable to a tray, i.e. approximately square and only slightly rectangular and in any case not elongated. In use, downwardly extending side walls enclose an air layer to give these known tray-shaped floats buoyancy. The known tray-shaped drifting trays are, for example, sprayed or pressed from a thin layer of plastic and are limp, which may be sufficient for the buoyancy of the drifting trays. The aim here is to provide simple and inexpensive drifting trays with a desired buoyancy and a desired degree of (manual) manageability of such drifting trays, and this is precisely where there is a problem with many cultivation systems from the prior art.
    Particularly in the case of crops, such as lettuce, bulk production is envisaged, and in connection therewith a high degree of automation. Scaling up the size of the known drift boxes offers no solution for this.
    In WO-2015/002529 of the Applicant, a cultivation system is proposed for growing certain crops on water in a basin, which lends itself to extensive automation and bulk production. With this cultivation system a largely automated embodiment is made possible for growing certain crops, such as lettuce, on water in a basin. The drift boxes are sufficiently robust and strong, even if very long drift boxes are used, which allows for mechanical processing, such as lifting drift boxes from the basin with at least approximately full grown crops and the associated weight in addition to the weight. weight of the drift boxes themselves. Such reinforced floats are also suitable for being engaged with a pivoting mechanism.
    A disadvantage of the floats described in WO-2015/002529 is that each float has a pattern of openings that is optimized for a certain type of crop, for example lettuce. If another crop is to be grown, the tray will perform sub-optimally, and is preferably exchanged for a drift tray optimized for this other type of crop. In addition, the bins sometimes proved difficult to close, which could cause leakage and the buoyancy of the floating bins decreased.
    An object of the present invention is to provide a float for growing crops on water, wherein the disadvantages mentioned do not occur, or at least to a lesser extent.
    Said object has been achieved according to the invention with the float for growing crops according to the present invention on water, comprising: - an elongated float, comprising at least one floating body which is hollow or made of a floating material, and which is in extends the longitudinal direction of the float - a lid that can be applied at the top to the elongated float, and which is provided with openings that form possible growing places for the crops; and - wherein the float and the lid are at least connectable to each other. Because the float and the lid are at least connectable to each other, a modular and easily assemblable system is created in which a float can be provided with a type of lid that is optimized for growing specific crops.
    According to a preferred embodiment, the float and the lid are releasably connectable to each other. A releasable connection provides the option of providing a floater with a different type of cover at a later stage as desired.
    According to a further preferred embodiment, the elongated float of the float is provided with openings, wherein one or more openings in the lid in a connected state of the float and the lid are in each case aligned with corresponding openings in the float, so that through openings are created which possible growing places for the crops. When the float and the lid are connected to each other, one or more openings in the lid and in the float are substantially aligned with each other, so that through openings are formed through which holders for the specific crop or roots of this crop can reach into the water to reach. The detachability of the connection between the float and the lid makes it possible to exchange the lid, so that the float can in each case be provided with a lid that is optimized for the crop to be grown at that time. The float can be provided with a fixed pattern of openings, while the choice of the lid determines which composite pattern of growing places is available after connection of the float and the lid.
    It is noted that the float is provided with floating bodies, and that they are therefore present in the float independently of the cover. Because the floating bodies are provided in the float and are not formed until after the composition of the float and the lid are formed, a relatively rigid and well-controllable cross-sectional shape of the floating body is provided, which makes a reliable closure, for example with sealing caps, possible.
    A particularly easily attachable and releasable, and at the same time reliable connection is obtained if, according to a preferred embodiment, a snap connection is provided with which the float and the cover can be releasably connected to each other.
    According to a further preferred embodiment, the elongated float is provided with a larger number of openings than the number of openings arranged in the cover.
    When the floater and the lid are connected to each other, only through openings will be formed at the locations where both the floater and the lid are provided with an opening. Because the cover is provided with fewer openings, these openings in the cover determine the places where through-openings in the assembled state of the float and the cover are formed through which holders for the crops or roots of the crops can reach into the water.
    The lid is provided with fewer openings than the float, as a result of which the lid will close one or more openings arranged in the float. This screening of openings that are not currently used for growing crops is advantageous, since this prevents (sun) light from passing through through openings that are not in use on the water. If (sun) light radiates into the water, this can cause an undesirable rise in the water temperature, which promotes unwanted algae growth.
    According to a further preferred embodiment, the float is provided with at least two rows of openings extending in the longitudinal direction thereof, the openings of adjacent rows being positioned substantially equally.
    According to a still further preferred embodiment, the cover is provided with at least two longitudinally extending rows of openings, wherein the openings of adjacent rows are staggered with respect to each other.
    According to a still further preferred embodiment, the float comprises at least two floating bodies which are connected to each other with a bridge part, and wherein at least one row of openings is arranged in the bridge part between these floating bodies.
    The advantage of arranging a row of openings between adjacent floating bodies is twofold. On the one hand, the construction is simplified because the floating bodies - which can be hollow and in that case have to be watertight - can themselves lack through openings. On the other hand, cultivation sites arranged between the floating bodies will have the advantage that an elongated air duct is formed under the cultivation sites. This air duct is enclosed on the sides between two adjacent floats, on the bottom by the water surface, and on the top by the side of the float facing the water surface. Such an elongated air duct connecting the different cultivation sites is advantageous, because all cultivation sites connected to elongated air duct are exposed to the same atmospheric conditions, which promotes their controllability. In the air duct, an interaction between oxygen and water takes place, and carbon dioxide is formed. An elongated air duct is also beneficial for the removal of this nitrogen dioxide, as ventilation can take place through this duct. In addition, only a few venting openings can be provided, which together discharge carbon dioxide from the entire elongated venting channel.
    According to a still further preferred embodiment, the float comprises at least three floating bodies extending in the longitudinal direction of the float, wherein adjacent floating bodies are in each case connected to one another by a bridge part, and wherein at least one row of openings is provided in at least two bridge parts.
    According to a still further preferred embodiment, the float comprises four floating bodies extending in the longitudinal direction of the float, wherein adjacent floating bodies are in each case connected to each other by a bridge part, and wherein only at least one row of through-going openings for forming cultivation places are provided in the two outer bridge parts. . By providing the float with four floating bodies, the required buoyancy is lowered and a floating body with smaller dimensions is sufficient. In the case of tubular floats, the diameter of the tubes can be reduced, thereby reducing the overall height of the float.
    If the floating bodies according to a still further preferred embodiment have a substantially round cross section at least at their ends, a reliable watertight seal can be obtained, as a result of which the floating box is less susceptible to leakage.
    If the floating body according to a still further preferred embodiment has a substantially round cross-section over substantially its entire length, round tubes can be used. In addition to its wide availability, this round shape has an additional advantage that its buoyancy increases non-linearly. As the drifting tanks are loaded more heavily and the round tubes come to lie deeper in the water, their buoyancy increases. This non-linear buoyancy is particularly advantageous because the buoyancy increases as the plant grows and the float becomes heavier.
    Although it is conceivable that one or more through-going openings are not utilized for growing crops but are deliberately kept free to remove carbon dioxide from the air ducts between the drip tray and the water surface, it is particularly advantageous if according to a further preferred embodiment at least in the cover has one or more vent openings.
    According to a still further preferred embodiment, one or more than one venting opening is furthermore provided in the float which, in an assembled state of the float and the lid, provides a continuous venting channel.
    It is noted that in a particularly advantageous embodiment the vent openings are arranged slightly offset with respect to each other, so that it is prevented that (sun) light can shine on the water through the vent channel that runs through these vent openings. The vent openings can be arranged both in a bridge section provided with openings for forming cultivation sites and in a bridge section located between cultivation sites.
    If, in a connected state of the float and the lid, the drip tray according to a still further preferred embodiment and a second aspect of the invention comprises a liquid chamber, each drift tray will form a separate compartment for a limited number of plants. Because the roots of the crop are collected within a drip tray and compartmentalized by the liquid chamber, the spread of diseases via the large basin of the cultivation system is prevented. After all, the roots no longer hang in the water of the basin, as a result of which spreading of possible diseases is in principle limited to the cultivation sites that form part of the same liquid chamber within a single drifting trough. According to this second aspect of the invention, the water in the basin is no longer used for supplying water to the roots, but serves as a transport system for the drift boxes.
    According to a still further preferred embodiment, the liquid chamber extends at least below the openings arranged in the lid which form possible cultivation places for the crops and the liquid chamber is bounded on the underside by the float. The floater seals the liquid chamber from the water in the basin, so that the roots are collected within a drip tray and do not come into direct contact with the water in the basin.
    Because the liquid chamber according to a still further preferred embodiment is in liquid communication with a liquid reservoir arranged on the top side of the drip tray, it is possible to supply new liquid from the liquid reservoir to the liquid chamber. A drip tray goes through a cultivation system and can be supplied with liquid continuously or periodically during the distance traveled. In addition to supplying fresh water, it is also conceivable that additional additives are administered at certain locations along the route.
    According to a still further preferred embodiment, the liquid chamber is bounded by one or more than one closing wall which is arranged near one end of the float.
    According to a still further preferred embodiment, one or more than one discharge opening is further provided near an end of the drip tray for discharging liquid from the liquid chamber. Dispersion of diseases is further prevented in that a regular or even continuous renewal of the liquid in the liquid chamber is possible.
    According to a still further preferred embodiment, the one or more than one discharge opening is arranged in the closing wall.
    According to a still further preferred embodiment of the drip tray with the liquid chamber, the float and the lid are integrated. The principle of providing a fluid chamber in a drifting basin is in principle separate from the drifting basin, which may or may not be in two parts, and is also applicable, for example, to drifting baskets made of one whole.
    The invention further relates to an assembly of a drifting tray as described with respect to the second aspect of the invention and a holder for growing crops, the holder comprising at least an upper part with larger dimensions than the dimensions of the in the cover openings and a lower part with smaller dimensions than the dimensions of the openings provided in the lid, and wherein the lower part of the container extends from the lid into the liquid chamber.
    The invention further relates to an assembly of a drifting tray as described with respect to the first aspect of the invention and a holder for growing crops, the holder comprising at least an upper part with larger dimensions than the dimensions of the in the cover provided openings and a lower part with smaller dimensions than the dimensions of the openings provided in the cover, and wherein the lower part of the holder extends from the cover beyond the corresponding openings in the float.
    According to a preferred embodiment of the float assembly according to the first or the second aspect of the invention, the holder comprises at least two projecting parts which define a larger dimension than the dimension of the openings provided in the cover.
    If the protruding parts of the container have a pot shape according to a preferred embodiment, a float can be used without further modification both for the use of normal pots and for the use of such a holder. It is even possible that a single float tray is partly provided with pots and partly with such holders.
    Such a container can be filled with a substrate that sucks up water from a water basin of a cultivation system, and is therefore suitable for growing crops that do not grow as a single plant, but as separate leaves. An example of such a crop is "baby leaf" lettuce.
    The invention further relates to a holder for growing crops as described in this application.

    Figure 1 shows a cultivation system 1 for crops for bringing the crops to maturity, such as lettuce, in drifting tanks on water. This cultivation system 1 is known from WO-2015/002529, and is explained here in simplified form for the sake of completeness.
    The cultivation system 1 comprises a basin 2 with water therein. The basin 2 comprises two elongated production ponds 3. In Figure 1, on the right-hand side, there is shown an input end 4 on a short side of the elongated production ponds 3 and the basin 2 assembled therefrom. Opposite the input end 4 is an output end 5.
    Large numbers of elongated drifting boxes 6 float in each of the production ponds 3, only a few of which are shown in Figure 1. The length of the drifting trays 6 essentially corresponds to the width of the elongated production ponds 3 and the drifting trays 6 float or are propelled in an orientation transverse to a longitudinal direction of the elongated production ponds 3. The drifting trays 6 are driven by one of the two production ponds 3 moved from the input end 4 to the output end 5 at a rate corresponding to the growth of the crops. The length of the production ponds 3 is adjusted to this, for example.
    As shown in Figure 2, the drift trays 6 each comprise a number of cultivation places 7 for the crops. In the cultivation sites 7, containers 13 for the crops or roots of the crops reach into the water, as is shown in Figure 3.
    The cultivation system 1 in figure 1 further comprises a transport system, not further explained here, which is adapted to remove the drifting trays 6 at the outlet end 5 from the water in the basin 2, whereafter they are transported via the at least one conveyor 10 as shortly as possible. can be moved again to the input end 4.
    Along the conveyor 10 along the long side 9 of the basin 2, various processing or processing stations are arranged, namely a cleaning station 17, a harvesting station 18, and a planting station 19. The cleaning station 17 is symbolically represented by spray nozzles. In order to strive for good cleaning, the drift trays 6 to be cleaned are preferably made of a smooth plastic.
    At the harvesting station 18, containers or trays are supplied and filled with harvested crops, and then discharged. Containers filled with young plants are supplied at the planting station 19, after which the young plants / crops are transferred to cultivation locations 7 in the drip trays 6.
    The cultivation system 1 comprises a propelling mechanism for moving the drifting trays 6 through the production ponds 3. The propelling mechanism comprises a tractor designed as an elastic cable 27, which cable 27 extends from the output end 5 to a cross-member 28 in the production pond 3. The cable 27 exerts a force in the direction of arrow B on the cross-member 28, so that floating trays 6 for the cross-member 28 are pulled towards the discharge end 5 in the direction of arrow B. Furthermore, the propelling mechanism comprises a retractor opposite the cable 27 relative to the crossbar 28, here in the embodiment of a selectively energizable winch 29. Connected to the crossbar 28, the drip trays 6 are advanced with this propelling mechanism to the output end 5 at a rate that corresponds to bringing the crops to maturity.
    In figure 2 a drifting tray 6 is shown, as it is known from WO-2015/002529. This drifting tray 6 from the prior art comprises two continuous beams 52, which are hollow but can alternatively be manufactured from solid or at least floating material. The beams 52 extend as reinforcement beams over substantially the entire length of the elongated drift tray 6. Between the beams 52 extend connecting plates 53.
    In addition to the connecting plates 53, back elements 54 are arranged between the beams 52. The back elements 54 comprise the openings 55 for receiving holders 13, as shown in Figure 3. In a specific embodiment of the holders, they can comprise a second shoulder 56 with a larger diameter d, whereby this second shoulder 56 can come to rest on the circumference of the openings 55 of the drift boxes 6. It is evident that also the connecting plates 53 comprise passages 57, for passage of either a bottom 58 of holders 13, or roots 59 of the crop grown in the holders 13. Preferably (only) the bottom of the holders 13 is submerged in the water. The openings 55, in combination with the passages 57, define the cultivation sites 7 of the drip trays 6.
    According to the preferred embodiment shown in Figure 4, the drip tray 60 according to the present invention comprises two rows of possible growing places 62, in which holders 13 can be accommodated. The float 60 comprises an elongated float 64 which in the embodiment shown comprises four floating bodies 66. The floating bodies 66 are hollow and are sealed watertight at their ends with sealing caps 68. In Figure 4, these sealing caps are partially hidden from view by the guide 74, which can optionally be provided for along the side walls of a basin 2 of a cultivation system 1 guiding the driveway 60.
    The driveway 60 further comprises a cover 86 which can be releasably connected to the float 64, for example with a snap connection, as further explained with reference to Fig. 7.
    Both the floater 64 and the lid 86 are provided with openings, respectively openings 78 in the floater 64 and openings 88 in the lid 86. The position of these openings 78, 88 is chosen such that when the floater 64 and the lid 86 with are connected to each other, the openings 88 in the lid 86 are in each case aligned with corresponding openings 78 in the float 64, so that through-going (cultivation) openings are created which form possible cultivation places 62 for the crops.
    In the cut-away perspective view of Figure 5, it can be seen that the float 60 is composed of a float 64 and a lid 86, which can be releasably connected to each other with a snap connection. To this end, the float 64 is provided with hook members 84, and the lid 86 with hook members 96 (Figure 7).
    The floater 64 is furthermore provided with floating bodies 66, whereby these are present in the float 64 independently of the lid 86. Because the floating bodies 66 are provided in the float 64, and are not formed until after the composition of the float 64 and the lid 86, a relatively rigid and well-controllable cross-sectional shape of the float body 66 is provided, which provides a reliable watertight seal, for example with sealing caps 68.
    The closing caps 68 can, for example, comprise a first closing part 70 and a second closing part 72, which increase in circumference with mutual rotation and can thus be clamped in the floating bodies 66 in a closing manner.
    The driver 64 comprises four floating bodies 66 which are connected to each other with a bridge part 80. In the embodiment shown, the two outer bridge parts 80 are provided with a row of openings 78. Corresponding openings 88 are provided in the lid 86, so that through (desired) openings are formed in which holders 13 can be received.
    Furthermore, vent openings 90 are provided through which carbon dioxide formed above the water surface can be discharged. Venting openings (not shown here) are also provided in the float 64, which are arranged offset in a particularly advantageous embodiment with respect to the venting openings 90 in the cover 86. This prevents (sun) light from heating the water in the basin 2 of the cultivation system 1 via the vent openings.
    An elongated air duct is formed under the cultivation sites (Figure 6). This air duct is enclosed on the sides between two adjacent floating bodies 66, on the underside by the water surface in the basin 2 of the cultivation system 1, and on the top by the side of the float 64 facing the water surface.
    In addition to the click connection with hook members 84, 94 already discussed, Figure 7 further shows that the cover 86 is provided with a profiling 92. On the one hand, this profiling provides an elevation that supports the holders 13 at the desired height, and on the other hand, it provides additional rigidity to the lid 86.
    Because the float 64 and the lid 86 are releasably connectable to each other, a modular and easily adaptable system is created in which a float 64 can be provided, if desired, with a type of lid 86 that is optimized for growing specific crops. Figures 8 and 9 show two possible configurations of a lid 86. When the float 64 and the lid 86 are connected to each other, one or more openings 88, 78 in the lid 86 and in the float 64 are substantially aligned with each other, so that through openings are formed through which holders for the specific crop or roots of this crop can reach into the water. In figure 8 the through-going (cultivation) openings are shown in dark shading.
    It is noted that the apertures 78 of the float 64 that are not shaded in Figure 8 are shielded by the lid 86 because it lacks a corresponding aperture 88. This screening of openings 78 that are not currently used for growing crops is advantageous, since it prevents the (sun) light from passing through openings, which are not in use, on the water in the basin 2 of the cultivation system 1. can shine. If (sun) light radiates into the water, this can cause an undesirable rise in the water temperature, which promotes unwanted algae growth.
    The detachability of the snap connection between the float 64 and the lid 86 makes it possible to exchange the lid 86, so that the float 64 can in each case be provided with a lid 86 that is optimized for the crop to be grown at that time. The float 86 is preferably provided with a fixed pattern of openings 88, while the choice of cover type 86 determines which composite pattern of cultivation sites 62 is available after connection of the float 64 with the cover 86.
    In figures 10-14 a further preferred embodiment is shown which comprises measures which in principle can also be applied to traditional drift boxes which are formed as a whole. It is not essential for the second aspect that the drip tray comprises an elongated float and a separate (replaceable) lid.
    For the sake of clarity, the cultivation system 101 according to Fig. 10 shows only one float tank 160 in a basin 102 and furthermore has many similarities with the cultivation system 1 explained with reference to Fig. 1. Both cultivation systems 1, 101 do distinguish themselves because above the float boxes 160 a liquid supply conduit 196 is provided which is provided along its length with a plurality of openings 197 to which, in the embodiment shown, downwardly extending side conduits 198 are provided.
    Figure 10 shows, in contrast to Figure 1, a single elongated production pond 103, but those skilled in the art will recognize that if desired, two or more elongated production ponds can be placed side by side, in accordance with the cultivation system of Figure 1.
    Liquid, such as water, which is supplied through the liquid supply line 196 flows via the openings 197 and the downwardly extending side lines 198 into at least one liquid reservoir 199 arranged on the float 160. This liquid reservoir 199 is at the top of the float 160 between cultivation sites 162 and is shown in detail in Figure 12.
    The float 160 shown in Figs. 10-14 furthermore shows many similarities with the float 60 according to the first aspect of the invention. The floating box 160 shown comprises two rows of possible growing places 162, in which holders 113 can be accommodated. The float 160 comprises an elongated float 164 which in the embodiment shown comprises four floating bodies 166. The floating bodies 166 are hollow and are sealed watertight at their ends with sealing caps 168.
    The drip tray 160 further comprises a cover 186 which can be releasably connected to the floater 164, for example with a snap connection already described with reference to Figure 7 and not further explained here.
    In contrast to the drift box 60 according to the first aspect of the invention, the drift boxes 160 according to this further preferred embodiment and second aspect of the invention are provided with openings 188 only in the lid 186, and the floater 164 lacks corresponding openings, in accordance with the openings 78 of the floating container 60. Thus, according to the second aspect, through-going (cultivation) openings are emphatically prevented, and the holders 113 only extend downwards through the openings 188 of the lid 186 (Fig. 14). The roots 159 are thus located in a space 201 between the float 164 and the cover 168. This space 201 forms part of a liquid chamber 202 which is enclosed at the sides between two floating bodies 166 and closing walls 200. The liquid chamber is limited at the bottom by a bridge part 180 of the float 164. In the embodiment shown, the closing walls 200 are arranged at the ends of the floating trays 160 between the closing caps 168, and can if desired be integrated with the closing caps 168.
    Because the fluid chamber 202 is in fluid communication with the fluid reservoir 199 via supply openings 203, the fluid chamber 202 can be provided via the fluid reservoir 199 with fluid supplied via the fluid supply line 196 of the cultivation system 101 (Fig. 13). During the cultivation process in which a drifting vessel 160 moves forward through the basin 102 of the cultivation system 101, the liquid chamber 202 can be supplied periodically or continuously with new liquid, such as fresh water. Near the ends of the drift boxes 160, these are provided with discharge openings 204, which can be formed on the one hand by a piercing 205 arranged in the closing wall 200 or on the other hand because the closing wall 200 has a limited height and thus an overflow edge 206 between the closing wall 200 and the cover 186. Due to the discharge, the liquid level in the liquid chamber 202 in principle remains at the height of the discharge opening 204, but in the event of a possible blockage thereof or an unexpectedly large supply of liquid, this can overflow over the edge 206 (Fig. 13).
    Because the roots 159 of the crop are collected within a drifting tank 160 and are compartmentalized by the liquid chamber 202 (Figure 14), the spread of diseases via the large basin 102 is prevented. After all, unlike the trays 60, the roots 159 no longer hang in the water of the basin 102, as a result of which spreading of any diseases is in principle limited to the cultivation sites 162 that form part of the same liquid chamber 202 within a single float tank 160. Diseases are further prevented in that a regular or even continuous renewal of the liquid in the liquid chamber 202 is possible.
    In the embodiment shown, the float 164 is again provided with floating bodies 166, so that these are present in the float 164 independently of the cover 186. Because the floating bodies 166 are provided in the float 164, and are not formed until after the composition of the float 164 and cover 186, a relatively rigid and easily controllable cross-sectional shape of the float body 166 is provided, which provides a reliable watertight seal, for example with sealing caps 168 , makes possible.
    The embodiments described above, although showing preferred embodiments of the invention, are only intended to illustrate the present invention and not to limit the description of the invention in any way.
    When measures in the claims are followed by reference numerals, such reference numerals only serve to contribute to the understanding of the claims, but are in no way restrictive of the scope of protection. In particular, it is noted that a person skilled in the art can combine technical measures of the various embodiments. The rights described are defined by the following claims in the scope of which many modifications are conceivable.
