    DESCRIPTION
    Improved forage distributor device
    5 Technical field of the invention
    The present invention corresponds to the technical field of the devices used to make the distribution of the forage destined to the grazing of animals, by the fields in which said pasture is made.
    10
    Background of the Invention
    In farms, the fodder used to feed livestock or other animals is of fundamental importance. One of the most widespread options of
    The conservation of the same is by means of a packaging in bales that are stored until the moment of offering them as food to the animals. The bales most used today are cylindrical bales of larger dimensions than the previous bales in the form of a parallelepiped.
    20 Once the bales are made, the next step is to feed the animals by shredding the forage contained in the bale, spreading it evenly across the grass fields.
    For this there are various types of machines, the most widespread being those that present
    25 a device that cuts the bale by means of sprockets, rollers or the like. These machines have the disadvantage that the resulting fodder is indicated for feeding in stables where the chopped fodder is not wasted, but not so for its distribution through open grass lands.
    30 Another possibility of distribution of bale forage is to carry out the process manually. Thus, in this case the bales are loaded on the trailer of a tractor and while the tractor moves through the fields, an operator on the trailer takes the fodder with a gallows and distributes it as the tractor advances.
    35 This mode also has drawbacks as it requires two operators: the tractor driver and the one on the trailer, and it is a slow and
    P201430506
    04-04-2014
    It depends on the physical strength of the operator in the trailer, so that large bales such as cylindrical are very expensive to distribute in this way.
    There are in turn some machines mounted on trailers prepared to load these bales and undo and distribute the forage through the area of grass while the trailer moves through it.
    As an example of the prior art, reference documents GB2158111, US3035729 and ES1056934-U can be mentioned.
    The first of these documents, reference GB2158111 refers to a machine for distributing fodder from cylindrical bales consisting of a frame on which the bale rotates driven by slats with spikes, moved by chains. The bale is unrolling and the fodder is falling down the side of the device.
    This machine has the disadvantage that the slats with skewers do not uniformly unwind the bale, and the forage is falling from the device through the area of irregularly shaped pastures. In addition, it is only allowed to load a single bale to distribute it, requiring moving to be loaded with a new bale when the initial bale is finished.
    The reference document US3035729 refers to a machine mounted on a trailer, where said machine has an axle with pallets that disintegrate the bale, tearing off the fodder and dropping it on the slats moved by chains that distribute it outside the trailer. There is another axle with vanes that serves to prevent the conveyor formed by the slats from expelling a large amount of fodder from the trailer at the same time.
    With this machine the conditions of the previous machines are improved, but it is very complicated with respect to them, due to the several axes perpendicular to each other that involve several gears of change of direction and a greater possibility of breakdowns. In addition, in the case of using cylindrical bales the device will be much less efficient.

    In order to solve these problems, there is another forage distributor device in the state of the art as defined in reference document ES1056934-U, of which the applicant himself is the owner.
    This document refers to a device adaptable to displacement means comprising a unwinding area of a cylindrical forage bale with propulsion means that move it towards the rear, where it meets a horizontal axis with a series of fins that in their turning movement push the bale making it turn towards the front area. This movement of turning the bale backwards combined with its forward movement due to the propulsion means generates a winding of the bale so that it exits the device from the rear, distributing it through the grass area as they travel means of travel.
    It also includes a bale deposit area located in front of the unwind zone and that when all the bale has already been distributed in the unwind zone, by means of a tilting movement, it deposits a new bale over said unwind zone to begin with the distribution Of the same.
    This distribution device has important advantages over the previous ones. Thus, it is possible to handle everything by a single operator who will drive the means of displacement of the device distributing the forage through the grass surface and when the bale is finished, activates the means that facilitate a second bale to move from the area from deposit to unwind, continuing with the distribution of this new bale. This means a greater capacity of fodder bales in the device, which means that less time is wasted in having to move the device to the bale storage area to load a new bale.
    In this way a greater productivity in the distribution is achieved, by minimizing the number of operators and achieving a reduction in distribution times. Likewise, it presents a fuel saving, an increase in the hectares that a device can supply, a greater ease of handling and with a simple mechanism, which therefore does not present excessive problems of operation and maintenance.
    However, this device still has a number of drawbacks. Thus, even having a deposit zone of one or two additional bales to which it is unrolling and distributing, this is insufficient in reality.

    In large-scale farms, the capacity of this distributor device is insufficient, since with two or three bales per path of the device it is not possible to cover the entire surface that agricultural holdings commonly present. Thus, at the end of the distribution of the bales loaded in the device, the tractor to which it is connected must return to the storage area of the farm, where two or three more bales are loaded to the device and must return to the point at which the initial charge was completed to continue with the distribution of the new bales.
    This supposes a huge waste of time, a greater expense in fuel, an extension of the times of distribution by the fields of grass… that entails a low productivity.
    In addition, the fact of not being able to supply the entire grassland with fodder in the shortest possible time and having to leave the supply interrupted due to the fact that it is necessary to return to load new bales in the device implies consequences on the animals themselves.
    Thus, if in an acceptable space of time, the fodder was distributed in a balanced way by the pastures, the animals would be distributed by them feeding quietly at a normal pace, given the tranquility of having enough food in their area of action. The welfare of these animals as well as their tranquility is a very important and necessary condition for them to enjoy perfect health and the products obtained from them are of high quality.
    On the contrary, if it happens as in this case, that the device must leave the distribution halfway to go to find more fodder, a process that lasts a considerable time while arriving at the warehouse area, the bales are loaded with the same tractor by pricking them and returning, the animals tend to be grouped in the area where the distribution has been made, and there may be unwanted encounters between an animal that is threatened or that wants to defend its leadership and its power over the food found in the area where he was first.
    In this way, well because they are forced to look for the food that others already consider theirs, such as having to defend it in case of being in the initial distribution area, nothing recommendable stress situations are generated in animals, which entails obtaining of lower quality products.

    Description of the invention
    The improved forage distributor device, which is presented here, is one of those used for the distribution of cattle pasture and is formed by a propelled carriage 5 adaptable to means of displacement along the surface on which said grass is made.
    This propelled carriage comprises an unrolling zone in the rear part according to the direction of travel, as well as a bale deposit zone in the front part thereof, tilting on the unrolling zone.
    Said unwind zone has a first clearing plane on which a first cylindrical forage bale is placed, while the deposit area has a second inclined deposit plane, suitable for at least one additional bale.
    15 In order to carry out the unwinding and distribution of the bale, the unwinding zone has means of propulsion of the first bale towards the final part of the car in which it has an outlet opening of the unwound bale whose height is defined by a series of fins that rotate around a horizontal axis simultaneously to the action of
    20 said propulsion means and in their movement push the bale towards the front of the unwinding area, generating the rotation and unwinding of the bale.
    This improved forage distributor device further comprises at least a first storage and unloading tilting platform that is located at a
    25 height on the first clearing plane or on the second inclined tank plane, this height being greater than the diameter of the bales located in said planes respectively and where the at least one tilting platform has a first end of unloading of the bales to the carriage propelled and a second opposite end of bale retention.
    Also, it comprises fastening means and tilting means of said at least one tilting platform.
    According to a preferred embodiment, the improved forage distributor device has two tilting platforms, one anterior and the other rear, depending on the direction of travel, which can be operated interchangeably and positioned such that the distance between the respective seconds
    P201430506
    04-04-2014
    the ends of both are greater than the sum of the lengths of the two tilting platforms, thus ensuring that the first ends thereof do not touch at any time in the tilting path thereof.
    Said two tilting platforms, according to another preferred embodiment, have different bale capacity each.
    According to another aspect of the invention, the tilting means of the at least one tilting platform in a preferred embodiment comprise driving means of the first end thereof, and a support and rotation axis located at the second end of the tilting platform According to one embodiment, these drive means are formed by a pneumatic or hydraulic cylinder.
    According to a preferred embodiment, the at least one tilting platform has a first loading position of the propelled carriage, with an inclination such that the first end thereof is higher than its second end. It also has a second loading and storage position of said at least one tilting platform in which it is found with an inclination close to the horizontal, so that its first end is higher than the second. And, a third unloading position in which said at least one tilting platform is inclined on the propelled carriage, with its first end in a position below its second end.
    According to a preferred embodiment, when the at least one tilting platform is the rear tilting platform and therefore, is located on the unwind zone, it comprises means for fixing the second loading and storage position thereof.
    These fixing means, according to a preferred embodiment, are formed by two folding support bars on a first end thereof which is respectively fixed to one of the sides of the deposit area, while the second end of each of said support bars in the second loading and storage position is coupled to a side respectively of the base of the tilting platform.

    Likewise, and according to a preferred embodiment, when the at least one tilting platform is located on the unwind zone, it comprises means for fastening the bales at the first end thereof.
    The fastening means of the at least one tilting platform to the propelled carriage, in accordance with a preferred embodiment of the invention are formed by at least two lateral fastening bars and a horizontal bar between them on which the second end is fastened. of one of the tilting platforms.
    According to a preferred embodiment, the at least one tilting platform comprises second means for securing the bales at the second end thereof.
    Also, and in accordance with another preferred embodiment, the at least one tilting platform comprises means for lateral fastening of the bales. These lateral fastening means, according to a preferred embodiment, are formed by an inclined side bar inclined from each side of the at least one tilting platform.
    With the improved forage distributor device proposed here, a significant improvement in the state of the art is obtained.
    This is so because a greater capacity of bales for the distributor device is achieved and this saves time and money, because less fuel is consumed and working times are shorter, as the time is required when a new one is required device charge.
    In addition, it is achieved by a simple device that therefore does not require many repairs or will cause major breakdowns. Also, the additional investment required by this device, even having greater capacity than those existing in the state of the art, is not greater. This is so, the loading of the device is carried out with the same tractor that constitutes the means of displacement of the device, which avoids the need to have a crane for these works and in addition, these means of displacement do not need to be of a great power, because with a tractor with a power of less than 75 HP it is possible to travel without problems, so that the necessary investment to be made in them is small.
    P201430506
    04-04-2014
    It is also possible to increase productivity thanks to the fact that only one operator is required to drive the means of movement as well as to drive the discharge of new forage bales in the propelled car when they have finished distributing the initial bales They were about him.
    5 It also has a very important advantage from the point of view of both animal and economic well-being, since both are related. So, if the animal is in perfect health and has led a pleasant and pleasant life, the products we obtain from it are of a very high quality, quite the opposite of the cases in which
    10 animals are uncomfortable, poorly maintained, stressed ...
    Thus, with this improved dispensing device, since the forage can be distributed more evenly over time on most of the pasture surface, the animals find the food easily, without having to move to areas
    15 further away or even face other animals to get it. Therefore, a much more peaceful and relaxed coexistence of animals is achieved, being this high quality of life which then provides very high quality products.

    Detailed description of a preferred embodiment of the invention
    10 In view of the figures provided, it can be seen how in a preferred embodiment of the invention, the improved forage distribution device proposed herein is one of those used in the distribution of cattle pasture, formed by a propelled carriage 1 adaptable to means of movement on the surface on which
    15 make such grass.
    As shown in Figures 1 to 4, the propelled carriage 1 has a unwind zone 2 with a first clearing plane 2.1 at the rear of the same according to the direction of travel, and a zone of bales 3 with a inclined background
    20 3.1 suitable for two additional 4 bales, in the part before it. This deposit zone 3 is tiltable on the unwind zone 2.
    Thus, the process begins with a first bale 4 of cylindrical fodder located on the first clearing plane 2.1 and two additional bales 4 on the second inclined plane 3.1.
    25 The unwind zone 2 in which said first clearing plane 2.1 is located has propulsion means that move said first cylindrical bale 4 towards the final part of the propelled carriage 1. In this final part, the propelled carriage 1 has an opening 5 exit of the unwound bale 20 whose height is defined by two fins 6 which rotate about a horizontal axis.
    30 Thus, the fins 6 push the bale 4 located in the unwinding zone 2 forward, simultaneously with the action of the propulsion means, which moves it backwards, generating the rotation and unwinding of said bale 4 which exits through the exit opening 5.

    In this preferred embodiment of the invention, as shown in Figure 4, the propulsion means are formed by two chains 8 that run along the sides of the first clearing plane 2.1 driven by pairs of wheels placed at the axle ends. horizontals located on the front side and on the rear side of said first clearing plane 2.1 and bars 9 that are attached to the chains 8 sliding on the first clearing plane 2.1 in a continuous movement. Likewise, each bar 9 has a plurality of skewers 10 perpendicular to it, to improve the drag of the forage.
    In addition, this improved distributor device has two tilting platforms 11,12, for storage and unloading, posterior and anterior according to the direction of travel, where the rear tilting platform 11, as shown in Figures 1 to 3, is located at a height on the first clearing plane 2.1, said height being greater than the diameter of the bale 4 located in said first clearing plane 2.1. On the other hand, the front tilting platform 12 is located at a height above the inclined second plane
    3.1 of deposit, said height being greater than the diameter of the bales 4 located in said second inclined plane 3.1.
    Likewise, both rear 11 and previous 12 tilting platforms 12 have a first end 11.1, 12.1, for unloading the bales to the propelled carriage 1 and a second end 11.2, 12.2, opposite the bale retention.
    In addition, the improved forage dispensing device comprises fastening means and tilting means of said tilting platforms 11, 12.
    Both tilting platforms 11, 12, can be operated interchangeably and are located such that the respective second ends 11.2, 12.2, are separated a distance greater than the sum of the lengths of both tilting platforms 11, 12.
    Also, as can be seen in Figures 1 to 3, the rear tilting platform 11 is suitable for a load of two forage bales 4 while the front tilting platform 12 has a capacity of a single bale 4.
    The tilting means of these tilting platforms 11, 12, in this preferred embodiment of the invention are formed by a support and turning axis 13 located at the second end 11.2, 12.2, of each tilting platform 11, 12, and by a means

    of operation of the first end 11.1, 12.1, of each platform, which in this way are formed by a hydraulic cylinder 14, on each side thereof.
    Both tilting platforms 11, 12, have three positions. Thus, each tilting platform has a first loading position of the propelled carriage 1, which can be seen in Figure 1, where both platforms are in said first position and as shown, both tilting platforms 11, 12, are inclined such that the first end 11.1, 12.1, is in a much higher position than the second end 11.2, 12.2.
    Figure 2 shows for both tilting platforms 11, 12, a second loading and storage position thereof, in which the two platforms have an almost horizontal position, the first end being 11.1, 12.1, somewhat elevated with respect to the second end 11.2, 12.2.
    Being both tilting platforms 11, 12, interchangeably operable, a possible situation is that shown in Figure 3 in which the front tilting platform 12 is in a second position for loading and storing bales while the rear tilting platform 11 it is in a third unloading position, in which the bales 4 of the propelled carriage 1 have been finished and a new bale 4 is unloaded in the propelled carriage 1 to continue unrolling it.
    In this situation, the rear tilting platform 11 is inclined on the propelled carriage 1, so that the first end 11.1 thereof is below its second end 11.2.
    In the case of the rear tilting platform 11, located on the unwind zone 2, this tilting platform has fixing means for the second loading and storage position thereof, which in this preferred embodiment of the invention are formed by two support bars 15 collapsible on a first end 15.1 thereof fixed to one of the sides respectively of the deposit area 3. The second end 15.2 of these two support bars 15 in this second position is coupled to a side respectively from the base of the rear tilting platform 11.
    This rear tilting platform 11 has, in turn, first fastening means for the bales 4 at the first end 11.1 thereof, which in this mode of
    P201430506
    04-04-2014
    Preferred embodiments are formed by a closing bar 16, while both the rear tilting platform 11 and the previous 12 comprise a second means for securing the bales 4 at the second end thereof, which are formed by containment bars 7 .
    5 Likewise, both tilting platforms 11, 12 have lateral fastening means of the bales 4, which in this preferred embodiment of the invention are formed, as shown in Figures 1 to 3, by two inclined side bars 18 and emerging respectively from one of the sides of each tilting platform 11, 12.
    10 As can be seen in Figures 1 to 3, the fastening means of both tilting platforms 11, 12, to the propelled carriage 1 in this preferred embodiment of the invention, are formed by two lateral clamping bars 19 on each side of the same and a horizontal connecting bar 17 between them. On these horizontal bars of
    15 junction 17 holds the second end 11.2, 12.2, of the respective tilting platform 11, 12.
    With the improved distributor device presented here, significant improvements are achieved with respect to the state of the art.
    20 Thus, with this improved device, a greater load capacity is obtained, which favors that the distribution of forage through the grass fields can be carried out more evenly in both space and time.
    25 Working times are reduced by spacing the time to go to the warehouse to load new bales, fuel consumption is also reduced and therefore CO2 emissions into the atmosphere and the device is perfectly usable by a single operator, which increases the productivity of the process.
    30 It is therefore a very effective device, which also has a simple constitution that favors the absence of breakdowns.
    Likewise, the investment in the means of displacement of the device, for example a tractor, is not greater than that of the existing devices, even if they are of less capacity, since with a tractor with a power lower than 75 HP it is possible to move
    P201430506 04-04-2014
    5 10 15 Perfectly the device proposed here. This tractor is responsible for loading the device, thus avoiding the need for an additional crane. In addition to all these factors, it is important to point out a great advantage of this device in relation to the living conditions of the animals whose feeding is directed. Thus, a uniform distribution of food is achieved over time and it is also less time that it takes to complete the process. By having a greater number of bales, it is possible to distribute them by a large part of the extension, much greater than in the devices of the state of the art, whereby, the animals are more peaceful and calm by having sufficient food and evenly for all of them. This balanced and stress-free life achieves happy and healthy animals that generate higher quality products.
