Description

Technical Field

[0001] This invention relates to the field of livestock breeding technology, and in particular to a pen suitable for donkey breeding. Background Technology

[0002] Animal husbandry is a production activity that utilizes the physiological functions of livestock, poultry, and special animals through artificial intervention to convert plant energy, such as feed, into animal energy, and produce products such as meat, eggs, milk, fur, cashmere, and medicinal herbs. It is one of the two pillars of agriculture and, together with crop farming, constitutes the food supply system.

[0003] In the conventional breeding process of donkeys, manure will accumulate in the pen. If it is not dealt with in time, it may lead to bacterial infection, hoof disease, skin disease and respiratory disease in donkeys. Therefore, it is necessary to clean the manure regularly. In the current pen cleaning, the manure is usually removed manually by shoveling it away bit by bit. The manure cleaning efficiency is low. Therefore, this application provides a pen suitable for donkey breeding to meet the needs of saving labor costs and improving production efficiency. Summary of the Invention

[0004] The purpose of this application is to provide a pen suitable for donkey farming, which solves the technical problem of low manure cleaning efficiency in the prior art.

[0005] To achieve the above objectives, this application provides the following technical solution: a pen suitable for donkey breeding, comprising a greenhouse installed on a concrete layer, wherein a feeding trough and a fence are provided inside the greenhouse, and further comprising a drive unit, a pusher plate and two sets of receiving troughs;

[0006] The pusher plate includes a front flat plate, two sets of side flat plates and two sets of side inclined plates. The two sets of side flat plates are installed perpendicularly to the front flat plate on the same side, and the two sets of side inclined plates are installed on the front flat plate in a figure-eight shape.

[0007] A set of material discharge openings is provided on the left and right sides of the concrete layer, and the two sets of material receiving grooves are located directly below the corresponding material discharge openings.

[0008] The drive unit is used to push the pusher plate from the leftmost side to the rightmost side. After the pusher plate is pushed, it can continue to push the pusher plate from the rightmost side to the leftmost side, and then the pusher plate flips over to return to its original position. The feces pushed by the pusher plate finally enter the corresponding receiving trough.

[0009] In a preferred embodiment of this invention, the drive unit includes two sets of reciprocating lead screws and a dual-axis drive motor mounted on the fence. Each of the two sets of reciprocating lead screws is equipped with a bevel gear and a moving nut. The output shaft of the dual-axis drive motor is equipped with a bevel gear, and the two sets of bevel gears on the same side are meshed together.

[0010] Both sets of movable nuts have uprights fixed to their lower ends, and the lower ends of both sets of uprights are rotatably connected to a rotating shaft. The pusher plate is mounted on the rotating shaft. An mounting plate is fixed between the two sets of uprights, and a worm gear is rotatably mounted on the mounting plate. The worm gear meshes with a worm wheel fixedly sleeved on the rotating shaft. A second one-way gear and a first one-way gear are arranged on the worm gear at the top and bottom, respectively. A first toothed rod and a second toothed rod adapted to the second one-way gear and the first one-way gear are arranged on the left and right sides of the concrete layer, respectively.

[0011] As a preferred embodiment of this invention, a shaking unit is also included, which is used to shake the feces attached to the pusher plate into the receiving trough.

[0012] In a preferred embodiment of this invention, the material shaking unit includes a first movable plate and a second movable plate respectively rotatably disposed on two sets of the side inclined panels. The other end of the first movable plate is rotatably connected to a third movable plate, and the other end of the second movable plate is rotatably connected to a fourth movable plate. The side end of the fourth movable plate is provided with a row of multiple sets of L-shaped rods, and the ends of the L-shaped rods are slidably disposed in the inner cavity of the third movable plate.

[0013] It also includes a magnetic suction unit, which uses magnetic force to make the first movable plate, the second movable plate, the third movable plate and the fourth movable plate fit tightly against the inner wall of the pusher plate. After the pusher plate rotates a certain angle, the magnetic fixation is released by the gravity of the first movable plate, the second movable plate, the third movable plate and the fourth movable plate.

[0014] In a preferred embodiment of this invention, the magnetic attraction unit includes multiple protective covers installed on the outer walls of the two sets of side slope panels. A permanent magnet is disposed inside the protective cover, and a through hole is provided on the side slope panel at a position corresponding to the permanent magnet.

[0015] As a preferred embodiment of this invention, a magnetic shielding unit is also included, which automatically shields and shields the permanent magnet when the first movable plate, the second movable plate, the third movable plate, and the fourth movable plate move, thereby causing the first movable plate, the second movable plate, the third movable plate, and the fourth movable plate to shake violently, and releases the magnetic shielding of the permanent magnet in advance before the first movable plate, the second movable plate, the third movable plate, and the fourth movable plate reset.

[0016] As a preferred embodiment of this invention, the magnetic shielding unit includes a magnetic shielding plate that is rotatably disposed in the through hole via a rotating rod, and a movable column with one end penetrating through the side inclined panel.

[0017] The other end of the movable column is fixedly connected to the inner cavity of the side inclined panel by a connecting spring. An abutment rod is fixed on the movable column, and the end of the abutment rod is located in the arc-shaped groove provided on the rotating rod.

[0018] In a preferred embodiment of this invention, two baffles are suspended on the left and right sides of the concrete layer, and the two sets of baffles are positioned close to the corresponding material discharge openings.

[0019] In summary, the technical effects and advantages of this invention are as follows:

[0020] The present invention has a reasonable structure. The present invention is equipped with a drive unit and a pusher plate. After the pusher plate completes the pusher operation, it can automatically flip over to prepare for the next push. At the same time, the pusher plate can prevent feces from accumulating higher than the pusher plate and falling into the cleaned area, thus avoiding the need for multiple back-and-forth cleaning.

[0021] In this invention, a shaking unit is provided. When rotating, the shaking unit shakes the feces attached to the push plate into the receiving trough, which is beneficial for removing stubborn feces from the push plate.

[0022] In this invention, a magnetic suction unit is provided, which makes each movable plate abut and fix against the inner wall of the pusher plate under the action of magnetic force;

[0023] In this invention, a magnetic shielding unit is provided, which helps to improve the collision strength between the third movable plate and the L-shaped rod, and further promotes the shaking off of feces attached to the push plate. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example: Reference Figure 1 and Figure 2 The enclosure shown is suitable for donkey breeding, including a greenhouse 1 installed on a concrete layer 2, a feeding trough 4 and a fence 3 inside the greenhouse 1, and also includes a drive unit, a pusher plate 10 and two sets of feeding troughs 20.

[0036] The pusher plate 10 includes a front flat plate 101, two sets of side flat plates 103 and two sets of side inclined plates 102. The two sets of side flat plates 103 are installed vertically on the same side as the front flat plate 101, and the two sets of side inclined plates 102 are installed on the front flat plate 101 in a figure-eight shape.

[0037] A set of material discharge openings 19 are provided on the left and right sides of the concrete layer 2, and two sets of material receiving troughs 20 are located directly below the corresponding material discharge openings 19.

[0038] The drive unit is used to push the pusher plate 10 from the leftmost to the rightmost. After the pusher plate 10 is pushed, it can continue to push the pusher plate 10 from the rightmost to the leftmost, and then make the pusher plate 10 flip back to its original position. The feces pushed by the pusher plate 10 finally enter the corresponding receiving trough 20.

[0039] The lower end of the pusher plate 10 is flush with the upper surface of the concrete layer 2. During use, the pusher plate 10 is controlled by the drive unit to move from left to right, and finally pushes the feces on the concrete layer 2 into the receiving trough 20 set on the right. When the pusher plate 10 moves to the top of the receiving trough 20 set on the right, it will automatically flip over, so that the end of the pusher plate 10 is facing outward, in preparation for the next push. At the same time, the pusher plate 10 is provided with a side inclined panel 102. The side inclined panel 102 set on the top has a guiding effect on the feces, which allows the feces to flow naturally to the front of the pusher plate, reducing the accumulation height and preventing the feces from falling into the cleaned area after the accumulation height exceeds the pusher plate 10, thus avoiding the need for multiple back-and-forth cleaning.

[0040] It should be noted that the height of the pusher plate 10 is set within the range that donkeys can cross (i.e., when the donkeys are in the pen, staff can also shovel manure), and the outer ends of the two inclined panels 102 and the two flat panels 103 on both sides of the pusher plate 10 are all triangular in structure, which makes it easy to clean the manure on the concrete layer 2.

[0041] As a preferred embodiment of this example, Figure 2-4 As shown, the drive unit includes two sets of reciprocating lead screws 5 mounted on the fence 3 and a dual-shaft drive motor 6. Each set of reciprocating lead screws 5 is equipped with a bevel gear 7 and a moving nut 8. The output shaft of the dual-shaft drive motor 6 is equipped with a bevel gear 7, and the two sets of bevel gears 7 on the same side are meshed together.

[0042] The lower ends of both sets of movable nuts 8 are fixed with uprights 9, and the lower ends of both sets of uprights 9 are rotatably connected to the rotating shaft 11. The push plate 10 is installed on the rotating shaft 11. An installation plate 14 is fixed between the two sets of uprights 9, and a worm gear 13 is rotatably installed on the installation plate 14. The worm gear 13 is meshed with a worm wheel 12 fixedly sleeved on the rotating shaft 11. A second one-way gear 16 and a first one-way gear 15 are arranged on the worm gear 13 at the top and bottom, respectively. A first toothed rod 17 and a second toothed rod 18 adapted to the second one-way gear 16 and the first one-way gear 15 are arranged on the left and right sides of the concrete layer 2, respectively.

[0043] When using, such as Figure 2As shown, the dual-shaft drive motor 6 drives two sets of reciprocating lead screws 5 to rotate, and the moving nut 8 drives the pusher plate 10 to move from left to right. Initially, the first gear 17 is engaged with the second one-way gear 16. When the pusher plate 10 moves from left to right, the first gear 17 cannot drive the worm gear 13 to rotate through the second one-way gear 16. When the pusher plate 10 moves to the top of the receiving groove 20 on the right, its first one-way gear 15 engages with the second gear 18. As the pusher plate 10 continues to move to the right, the first one-way gear 15 drives the worm gear 13 to rotate, and the worm gear 13 drives the worm wheel 12 to rotate, thereby... The rotating shaft 11 drives the pusher plate 10 to rotate 180° clockwise. After the pusher plate 10 has rotated, the dual-shaft drive motor 6 stops moving, and the pusher plate 10 stops moving. When it is necessary to clean up the feces later, the dual-shaft drive motor 6 can be controlled to work, driving the pusher plate 10 to move from right to left to push the feces. When the pusher plate 10 moves to the top of the left receiving trough 20, the second one-way gear 16 is engaged with the first gear 17. As the pusher plate 10 continues to move to the left, the second one-way gear 16 drives the worm gear 13 to rotate in the opposite direction, and finally the pusher plate 10 rotates 180° in the opposite direction to return to its original position and then stops moving.

[0044] The rotation of the pusher plate 10 serves two purposes: first, to change the direction of the pusher end of the pusher plate 10 so that it can push materials back and forth; second, when the pusher plate 10 is flipped, the feces attached to the pusher end surface of the pusher plate 10 can fall into the receiving trough 20 by its own gravity, which is beneficial to cleaning the feces on the pusher plate 10.

[0045] As a preferred embodiment of this invention, a shaking unit is also included, which is used to shake the feces attached to the pusher plate 10 into the receiving trough 20.

[0046] During rotation, the feces attached to the pusher plate 10 are shaken off into the receiving trough 20 by the shaking unit, which is beneficial for removing stubborn feces from the pusher plate 10.

[0047] As a preferred embodiment of this example, Figure 5 As shown, the material shaking unit includes a first movable plate 104 and a second movable plate 106 respectively rotatably mounted on two sets of side inclined panels 102. The other end of the first movable plate 104 is rotatably connected to a third movable plate 105, and the other end of the second movable plate 106 is rotatably connected to a fourth movable plate 107. The side end of the fourth movable plate 107 is provided with a row of multiple sets of L-shaped rods 108, and the ends of the L-shaped rods 108 are slidably mounted in the inner cavity of the third movable plate 105.

[0048] It also includes a magnetic suction unit, which uses magnetic force to make the first movable plate 104, the second movable plate 106, the third movable plate 105 and the fourth movable plate 107 stick tightly to the inner wall of the pusher plate 10. After the pusher plate 10 rotates a certain angle, the magnetic fixation is released by the gravity of the first movable plate 104, the second movable plate 106, the third movable plate 105 and the fourth movable plate 107.

[0049] When the pusher plate 10 pushes material, its first movable plate 104, second movable plate 106, third movable plate 105, and fourth movable plate 107 are magnetically fixed and closely adhered to the inner wall of the pusher plate 10. After the pusher plate 10 rotates at a certain angle, the gravity of the first movable plate 104, second movable plate 106, third movable plate 105, and fourth movable plate 107 is greater than the magnetic force. At this time, the first movable plate 104, second movable plate 106, third movable plate 105, and fourth movable plate 107 will suddenly move away from the inner wall of the pusher plate 10. When the pushing end of the pusher plate 10 faces downward, the movable plates finally form... Figure 8 As shown in the diagram, before this state is formed, each movable plate moves away from the inner wall of the pusher plate 10 by gravity. When the movement is completed, the end of the third movable plate 105 will contact and collide with the L-shaped rod 108, which will cause each movable plate to shake and shake off the feces attached to each movable plate. When the pusher plate 10 returns to its original position, through the gravity of some of the movable plates and the magnetic force, each movable plate is finally magnetically attracted and fixed and tightly attached to the inner wall of the pusher plate 10.

[0050] It should be noted that: First, all movable plates are made of iron and have an anti-corrosion coating on their outer surface to prevent corrosion; Second, the sides of the third movable plate 105, the fourth movable plate 107, the second movable plate 106 and the first movable plate 104 will scrape off and shake off the feces attached to the two sets of side plane plates 103.

[0051] As a preferred embodiment of this example, Figure 5 and Figure 6 As shown, the magnetic attraction unit includes multiple protective covers installed on the outer walls of two sets of side inclined panels 102. Permanent magnets 28 are provided inside the protective covers, and through holes 29 are provided on the side inclined panels 102 at positions corresponding to the permanent magnets 28.

[0052] Initially, the permanent magnet 28 magnetically fixes each movable plate. When the pusher plate 10 rotates, the downward gravity of each movable plate is greater than the magnetic force, causing each movable plate to move downward and the third movable plate 105 to contact and collide with the L-shaped rod 108, shaking off the feces on the pusher plate 10. After the pusher plate 10 rotates back to its original position, the first movable plate 104 moves closer to the side inclined panel 102, and under the action of the magnetic force, each movable plate abuts and is fixed against the inner wall of the pusher plate 10.

[0053] As a preferred embodiment of this invention, a magnetic shielding unit is also included, which automatically shields the permanent magnet 28 when the first movable plate 104, the second movable plate 106, the third movable plate 105, and the fourth movable plate 107 move, thereby causing the first movable plate 104, the second movable plate 106, the third movable plate 105, and the fourth movable plate 107 to vibrate more violently, and releases the magnetic shielding of the permanent magnet 28 in advance before the first movable plate 104, the second movable plate 106, the third movable plate 105, and the fourth movable plate 107 reset.

[0054] When each movable plate moves away from the inner wall of the pusher plate 10, the permanent magnet 28 will be shielded by the magnetic shielding unit, blocking the magnetism and preventing the permanent magnet 28 from exerting a force on the movable plate in the opposite direction of the movable plate's movement. This reduces the resistance to the downward movement of each movable plate, which is beneficial to improving the collision strength between the third movable plate 105 and the L-shaped rod 108, and further promotes the shaking off of the feces attached to the pusher plate 10.

[0055] During the process of each movable plate returning to its original position, it will automatically release the obstruction of the permanent magnet 28. At this time, the magnetic force of the permanent magnet 28 will cause each movable plate to be magnetically fixed and tightly attached to the inner wall of the push plate 10.

[0056] As a preferred embodiment of this example, Figure 6 As shown, the magnetic shielding unit includes a magnetic shielding plate 21 that is rotatably disposed in a through hole 29 via a rotating rod 22, and a movable column 24 that penetrates one end of the side inclined panel 102.

[0057] The other end of the movable column 24 is fixedly connected to the inner cavity of the side inclined panel 102 via a connecting spring 26. An abutment rod 25 is fixed on the movable column 24, and the end of the abutment rod 25 is located in the arc groove 23 provided on the rotating rod 22.

[0058] Initially, each movable plate is in close contact with the inner wall of the pusher plate 10, which will cause contact with the end of the movable column 24. At this time, the connecting spring 26 is in a compressed state, and the magnetic shielding plate 21 does not block the permanent magnet 28.

[0059] When each movable plate moves away from the inner wall of the pusher plate 10, the first movable plate 104 releases the pressure on the end of the movable column 24. Under the action of the elastic force of the connecting spring 26, one end of the movable column 24 moves outward. Through the abutment rod 25, the rotating rod 22 drives the magnetic shielding plate 21 to rotate, thereby blocking the permanent magnet 28, releasing the magnetic force between the permanent magnet 28 and the movable plate, and thus accelerating the movement of the movable plate away, which is conducive to promoting intense collision (the purpose of which is to promote the shaking off of the feces attached to the movable plate).

[0060] When each movable plate moves close to the inner wall of the pusher plate 10, the first movable plate 104 will first squeeze the movable column 24, which will cause the magnetic shielding plate 21 to rotate and release the shielding of the permanent magnet 28. Through the magnetic force of the permanent magnet 28, each movable plate will eventually be magnetically fixed and tightly attached to the inner wall of the pusher plate 10.

[0061] As a preferred embodiment of this example, Figure 2 As shown, two sets of baffle plates 27 are suspended on the left and right sides of the concrete layer 2, and the two sets of baffle plates 27 are set close to the corresponding material discharge openings 19.

[0062] The barrier 27 is used to block the donkeys inside the pen and restrict their range of movement. Its suspended setting facilitates the passage of the feed pusher 10 from below.

[0063] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
