Description

Technical Field

[0001] This utility model relates to the field of animal husbandry technology, and in particular to an automatic feeder for animal husbandry. Background Technology

[0002] Animal husbandry, as a crucial link in agriculture, together with crop farming, constitutes the two core pillars of agricultural production. Animal husbandry is a comprehensive discipline, encompassing various aspects such as livestock breeding, reproduction, feeding management, disease control, grassland construction, livestock product processing, and business management. In the practical operation of livestock farming, feed dispensers have become indispensable tools, responsible for the precise delivery of feed, ensuring the smooth progress of the breeding process, thereby improving the efficiency and effectiveness of livestock production.

[0003] A search revealed a patent (CN220140473U) for an automatic feeder for cattle and sheep. This device involves turning on a motor, which rotates a first screw to move a feed hopper on top of a moving block horizontally. Opening a shut-off valve allows feed to be poured evenly from the hopper onto the inside of a feeding trough for the cattle and sheep to eat. This effectively reduces the need for manual spreading and stacking of feed in the trough after feeding, simplifying the operation and reducing labor input. However, cattle and sheep often spill feed from the trough while eating, causing it to fall onto the first screw. This spilled feed accelerates wear between the screw and the moving block, shortening the device's lifespan and increasing the frequency and cost of replacing parts. Furthermore, feed residue and wear debris are difficult to clean thoroughly, causing the feeding trough to vibrate during movement and resulting in uneven feed distribution. Therefore, this application proposes an automatic feeder for livestock farming. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an automatic feeder for livestock farming.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic feeder for livestock farming includes a feeding trough and a storage bin. A first fixed plate and a second fixed plate are fixedly connected to the sidewalls of the feeding trough. A moving mechanism for moving the storage bin is installed between the sidewalls of the first and second fixed plates. A groove is formed in the sidewall of the second fixed plate, and a gear is rotatably connected within the groove. A rack is slidably connected within the groove, and the rack meshes with the gear. A push plate is connected to the rack via a reset mechanism. An L-shaped frame is fixedly connected to the upper end of the second fixed plate. A screw is rotatably connected to the upper wall of the L-shaped frame. The screw passes through the second fixed plate and is fixedly connected to the gear. A nut is threaded onto the screw. A limiting mechanism for limiting the nut is installed on the L-shaped frame. A fixed rod is fixedly connected to the sidewall of the nut. A baffle is fixedly connected to the end of the fixed rod away from the nut, and the baffle slidably passes through the feeding trough. A discharge plate is connected to the sidewall of the storage bin.

[0007] Preferably, the lower end of the feeding trough is fixedly connected to two fixing frames, and the lower end of the fixing frames is fixedly connected to a base plate.

[0008] Preferably, the moving mechanism includes a threaded sleeve and a threaded rod, the threaded rod is rotatably mounted between the second fixed plate and the side wall of the first fixed plate, the threaded sleeve is threaded onto the threaded rod, the storage bin is fixedly mounted on the upper end of the threaded sleeve, and a guide mechanism for guiding the threaded sleeve is installed on the side wall of the feed trough.

[0009] Preferably, a motor is fixedly connected to the side wall of the first fixing plate, and the output shaft of the motor is fixedly connected to the threaded rod.

[0010] Preferably, the reset mechanism includes two springs, one end of which is fixedly mounted on the side wall of the second fixed plate, and the other end of which is fixedly mounted on the side wall of the push plate.

[0011] Preferably, the limiting mechanism includes a slider, which is fixedly installed on the side wall of the nut, and a groove is provided on the inner wall of the L-shaped frame, in which the slider slides.

[0012] Preferably, the guiding mechanism includes a slide plate, which is fixedly installed on the side wall of the threaded sleeve. The side wall of the feeding trough is provided with a slide rail, and the slide plate slides within the slide rail.

[0013] This utility model has the following beneficial effects:

[0014] The feed hopper moves above the feeding trough, allowing the feed inside to fall evenly into the trough through the feed plate for the cattle and sheep to eat. When the feed hopper moves to contact the push plate, the push plate drives the rack to move, which in turn causes the gear to rotate, which in turn causes the screw to rotate. The rotation of the screw causes the nut to move upward, which in turn causes the fixed rod to move the baffle upward, thus blocking the feed spilled by the cattle and sheep and preventing the feed from falling onto the threaded rod. This avoids wear between the threaded sleeve and the threaded rod, keeps the feed hopper stable during movement, and prevents uneven feed distribution. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 An automatic feeder for livestock farming includes a feed trough 1 and a storage bin 2. A first fixing plate 4 and a second fixing plate 13 are fixedly connected to the side wall of the feed trough 1. A moving mechanism for moving the storage bin 2 is installed between the side walls of the first fixing plate 4 and the second fixing plate 13. The moving mechanism includes a threaded sleeve 14 and a threaded rod 15. The threaded rod 15 is rotatably installed between the side wall of the second fixing plate 13 and the side wall of the first fixing plate 4. The threaded sleeve 14 is threaded onto the threaded rod 15. The storage bin 2 is fixedly installed on the upper end of the threaded sleeve 14.

[0022] A guide mechanism for guiding the threaded sleeve 14 is installed on the side wall of the feeding trough 1. The guide mechanism includes a slide plate 22, which is fixedly installed on the side wall of the threaded sleeve 14. A slide rail 23 is provided on the side wall of the feeding trough 1, and the slide plate 22 slides within the slide rail 23.

[0023] The second fixed plate 13 has a groove 24 on its side wall. A gear 20 is rotatably connected in the groove 24, and a rack 21 is slidably connected in the groove 24. The rack 21 meshes with the gear 20. It should be noted that the rack 21 slides tightly against the side wall of the groove 24. In this way, the inner wall of the groove 24 can be used to limit the rack 21, so that the rack 21 and the gear 20 are always meshed, preventing the rack 21 from disengaging from the gear 20 and preventing the gear 20 from being unable to rotate, which would prevent the baffle 12 from being unable to move up or down.

[0024] The rack 21 is connected to the push plate 18 via a reset mechanism. The reset mechanism includes two springs 19. One end of each spring 19 is fixedly mounted on the side wall of the second fixed plate 13, and the other end is fixedly mounted on the side wall of the push plate 18. It should be noted that the function of the springs 19 is that when the storage bin 2 is not in contact with the push plate 18, the springs 19 reset, causing the push plate 18 to move back to its original position, thereby causing the screw 9 to rotate in the opposite direction. This causes the baffle 12 to move downwards, preventing obstruction of the movement of the storage bin 2.

[0025] An L-shaped frame 8 is fixedly connected to the upper end of the second fixed plate 13. A screw 9 is rotatably connected to the upper inner wall of the L-shaped frame 8. The screw 9 passes through the second fixed plate 13 and is fixedly connected to the gear 20. A nut 10 is threaded onto the screw 9. A limiting mechanism for limiting the nut 10 is installed on the L-shaped frame 8. The limiting mechanism includes a slider 16. The slider 16 is fixedly installed on the side wall of the nut 10. A groove 17 is opened on the inner wall of the L-shaped frame 8. The slider 16 slides in the groove 17.

[0026] A fixing rod 11 is fixedly connected to the side wall of the nut 10. A baffle 12 is fixedly connected to the end of the fixing rod 11 away from the nut 10. The baffle 12 slides through the feeding trough 1, and a discharge plate 3 is connected to the side wall of the storage bin 2. It should be noted that the length of the baffle 12 plus the length of the storage bin 2 is exactly the length of the feeding trough 1. This ensures that when the storage bin 2 comes into contact with the push plate 18, the baffle 12 moves upward. The upward movement of the baffle 12 will not collide with the discharge plate 3, thus avoiding damage to the parts.

[0027] Two fixed brackets 6 are fixedly connected to the lower end of the feeding trough 1, and a base plate 7 is fixedly connected to the lower end of the fixed brackets 6. It should be noted that the function of the base plate 7 is to increase the contact area between the equipment and the ground, so that the equipment can operate more stably and prevent the equipment from tilting and causing the feed in the feeding trough 1 to spill out, thus avoiding feed waste.

[0028] A motor 5 is fixedly connected to the side wall of the first fixed plate 4, and the output shaft of the motor 5 is fixedly connected to the threaded rod 15.

[0029] In this invention, feed is poured into the storage bin 2, and the motor 5 is started. The motor 5 drives the threaded rod 15 to rotate. Since the slide plate 22 slides in the slide rail 23, the side wall of the slide rail 23 limits the slide plate 22. Therefore, the rotation of the threaded rod 15 causes the threaded sleeve 14 to slide along the slide rail 23, which in turn causes the threaded sleeve 14 to move the storage bin 2 at the upper end of the feed trough 1, so that the feed in the storage bin 2 falls evenly into the feed trough 1 through the feed plate 3 for cattle and sheep to eat.

[0030] like Figure 1 As shown, as the storage bin 2 moves to the right, it comes into contact with the push plate 18. The push plate 18 drives the rack 21 to move to the right. Since the rack 21 meshes with the gear 20, the movement of the rack 21 drives the gear 20 to rotate. At this time, the spring 19 is compressed, and the rotation of the gear 20 drives the screw 9 to rotate, which in turn causes the nut 10 to move upward. The nut 10 drives the baffle 12 to move upward through the fixing rod 11. The baffle 12 and the side wall of the storage bin 2 together block the feed, preventing the feed from falling onto the threaded rod 15. When the storage bin 2 moves from the left to the right, the feed in the storage bin 2 has just finished falling. After the cattle and sheep have finished eating and drinking, the reverse start motor 5 rotates, causing the feed bin 2 to move back to the left side for the next feeding. When the feed bin 2 moves to the right, the compressed spring 19 returns to its original position, causing the push plate 18 to move to the right, which in turn causes the gear 20 to rotate in the reverse direction, thereby causing the screw 9 to rotate in the reverse direction. This allows the baffle 12 to be moved down into the feed trough 1, preventing it from obstructing the movement of the feed bin 2.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
