Description

Technical Field

[0001] This invention relates to the field of livestock feed equipment technology, specifically an automatic feed replenishment and dispensing device for cattle and sheep. Background Technology

[0002] With the rapid development of livestock farming towards large-scale and intensive operations, the requirements for efficiency, precision, and automation in the feed delivery process for cattle and sheep are increasing. As a key link affecting the growth rate, feed utilization rate, and economic benefits of cattle and sheep, the performance of the equipment used for feed delivery directly determines the convenience and scientific nature of livestock management.

[0003] Currently, the following problems are commonly found in cattle and sheep feed dispensing equipment on the market: Insufficient feed storage and sorting capabilities: Most equipment uses a single-chamber storage structure, which cannot separately store different types of feed such as concentrates and roughage. Mixing different feeds can easily lead to cross-contamination of nutrients or imbalance in the ratio of nutrients, and it is impossible to flexibly adjust the proportion of feed types according to the needs of cattle and sheep at different growth stages.

[0004] Lack of feed pretreatment: The roughage (such as straw and hay) consumed by cattle and sheep is often in chunks or strips. If it is fed directly without cutting, it will not only reduce the digestibility and absorption efficiency of cattle and sheep, but may also make it difficult for them to eat due to the large volume of the feed. Most existing equipment lacks integrated cutting mechanisms, requiring manual pretreatment of roughage, which increases the labor costs and complexity of the process in animal husbandry.

[0005] Poor automation and continuity of feed dispensing: Traditional feed dispensing relies heavily on manual handling or semi-automatic equipment. In large-scale farming scenarios, not only is a large amount of manpower required for timely dispensing, but it is also difficult to ensure the accuracy of dispensing time and the consistency of dispensing amount. Problems such as missed dispensing and over-dispensing are prone to occur, affecting the growth rhythm of cattle and sheep. At the same time, some equipment's feed pipes lack anti-clogging design, and feed can easily clog the pipes after it gets damp and clumps together, leading to dispensing interruptions and further reducing farming efficiency.

[0006] Low feed mixing uniformity and feeding accuracy: Cattle and sheep farming often requires mixing various feeds in specific proportions to meet nutritional needs. However, existing equipment often lacks a dedicated mixing mechanism, with different feeds falling directly from the storage box into the feeding trough, easily leading to stratification and uneven nutritional intake for cattle and sheep. Furthermore, feeding is often done at fixed locations, making it impossible to dynamically adjust the feeding location and dosage based on the remaining feed in the trough or the distribution of cattle and sheep, easily resulting in feed waste or localized insufficient feeding. To address these problems, this invention proposes an automatic feed replenishment device for cattle and sheep in livestock farming. Summary of the Invention

[0007] To address the problems in existing technologies, this invention proposes an automatic feed replenishment and dispensing device for cattle and sheep, which solves the problem that existing equipment lacks functions such as classified storage, integrated cutting, automatic mixing, anti-blocking feeding, and precise replenishment for automatic feed replenishment and dispensing.

[0008] The technical solution adopted by this invention to solve its technical problem is: an automatic feed replenishment and dispensing device for cattle and sheep in livestock farming, including a mounting plate. The upper end of the mounting plate is fixedly connected to symmetrically arranged storage boxes filled with different feeds. Each storage box has a filling tube fixedly connected to one side. The storage boxes are rotatably connected to a first rotating rod via bearings. One of the storage boxes has a drive motor fixedly connected to its upper end via a bracket. The output end of the drive motor is fixedly connected to the wall of one of the first rotating rods. The upper wall of each first rotating rod is fixedly connected to a first transmission wheel, which together drive a first belt. The lower wall of each first rotating rod is fixedly connected to symmetrically arranged cutting blades. Each storage box has a feeding pipe fixedly connected to its lower end. The lower end of the feeding pipe passes through the mounting plate and extends to its lower end. The lower end of each first rotating rod is fixedly connected to a second rotating rod, which extends into the feeding pipe. The wall of the second rotating rod is fixedly connected to a threaded fan blade. An electric valve is fixedly installed on the lower wall of the feeding pipe.

[0009] Specifically, the upper end of the storage box away from the drive motor is rotatably connected to a transmission rod via a bracket and bearing. A first bevel gear is fixedly connected to one side of the transmission rod, and a second bevel gear is meshed with the lower end of the first bevel gear. The second bevel gear is fixedly connected to a first rotating rod. A second transmission wheel is fixedly connected to the other side of the transmission rod. The lower end of the mounting plate is fixedly connected to an open mixing box via a bracket. The wall of the mixing box is rotatably connected to a third rotating rod via bearing. A mixing plate is fixedly connected to the middle wall of the third rotating rod, and a third transmission wheel is fixedly connected to the wall of the third rotating rod away from the mixing plate. The third transmission wheel and the second transmission wheel are jointly connected to a second belt. A symmetrically arranged flow pipe is fixedly connected to the lower end of the mixing box, and an electric valve is fixedly connected to the upper wall of the flow pipe.

[0010] Specifically, a stepper motor is fixedly connected to the lower end of the mixing box, a fixed rod is fixedly connected to the output end of the stepper motor, a circular feeding box is fixedly connected to the output end of the fixed rod, fixed plates are fixed on both sides of the lower end of the fixed rod, the opposite side of the fixed plate is fixedly connected to the inner wall of the mixing box, and several stirring plates are fixedly connected to the lower end of the fixed plate.

[0011] Specifically, a discharge port is opened through one side of the lower end of the replenishment box, and a positioning plate is fixedly connected to the outer wall of the replenishment box on the side of the discharge port. The positioning plate is rotatably connected to an electric telescopic rod by a rotary pull. The output end of the electric telescopic rod is rotatably connected to a baffle with a timing sensor at the bottom end by a rotating shaft. A connecting column is fixedly connected to one side of the upper end of the baffle. The upper end of the connecting column is rotatably connected to the lower end of the replenishment box by a bearing. The baffle and the lower end of the discharge port are in contact, and the timing sensor on the baffle and the electric telescopic rod are wirelessly connected.

[0012] Specifically, an annular groove is formed on the outside of the feeding box, and U-shaped rods are slidably connected to both sides of the annular groove via slide rails and sliders. The upper end of the U-shaped rods is fixedly connected to the outer wall of the mixing box.

[0013] Specifically, a T-shaped plate for mounting and suspending is fixedly connected to one side of the outer wall of the mixing box.

[0014] Specifically, the reverse-rotating threaded fan blades of the drive motor will lift and cut the feed in the feed pipe, while the forward-rotating threaded fan blades will lower the cut feed from the feed pipe.

[0015] The beneficial effects of this invention are: (1) The present invention provides an automatic feed replenishment device for cattle and sheep. The device is equipped with symmetrically arranged storage boxes, which can be filled with different types of feed such as concentrate and roughage, to avoid cross-contamination of nutrients or imbalance of ratio caused by mixed storage. It can also flexibly adjust the feed ratio according to different growth stages of cattle and sheep. At the same time, the symmetrical cutting blades at the lower end of the first rotating rod can cut block and strip roughage, which solves the problem that existing equipment lacks pre-treatment function and requires manual pre-treatment of roughage, thereby improving the digestion and absorption efficiency of cattle and sheep while reducing the labor input of breeding. (2) The automatic feed replenishment and dispensing device for cattle and sheep breeding described in this invention is driven by a drive motor to rotate the first rotating rod, and works in conjunction with the first belt to achieve synchronous operation of the two storage boxes; the second rotating rod at the lower end of the first rotating rod extends into the feed pipe, and the threaded fan blades on its rod wall can achieve "feeding down after cutting" and "feeding up and cutting the clumped feed" respectively by the forward and reverse rotation of the drive motor. Combined with the electric valves of the feed pipe and the flow pipe for precise quantity control, it solves the problems of traditional equipment relying on manual feeding, easy to miss or over-feed, and the problem of feed clumping and blocking due to moisture in the feed pipe, ensuring accurate feeding time and continuous process; (3) The automatic feed replenishment device for cattle and sheep in the present invention can fully mix different feeds by the third rotating rod and mixing plate in the mixing box, avoiding the stratification caused by the direct fall of feed, and ensuring the balanced nutrition of cattle and sheep; the feed box is driven to rotate by a stepper motor, and the cooperation of the external annular groove and U-shaped rod can help the feed box to be positioned stably. At the same time, the timing sensor on the baffle is wirelessly linked with the electric telescopic rod, which can dynamically adjust the feeding position and dosage according to the remaining amount of feed in the trough or the distribution of cattle and sheep, thus solving the problems of uneven mixing and fixed position feeding in existing equipment, which easily leads to feed waste or insufficient local feeding.

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0020] like Figures 1-7 As shown, the present invention provides the following technical solution: Example 1: An automatic feed replenishment and dispensing device for cattle and sheep in livestock farming includes a mounting plate 1. The upper end of the mounting plate 1 is fixedly connected to symmetrically arranged storage boxes 2, each filled with different types of feed. Each storage box 2 has a filling tube fixedly connected to one side. The storage boxes 2 are rotatably connected to a first rotating rod 3 via bearings. One of the storage boxes 2 has a drive motor 4 fixedly connected to its upper end via a bracket. The output end of the drive motor 4 is fixedly connected to the wall of one of the first rotating rods 3. First transmission wheels 5 are fixedly connected to the upper walls of the first rotating rods 3. The first transmission wheels 5 are collectively connected to a first belt 6. The lower end of the first rotating rod 3 is fixedly connected to the symmetrically arranged cutting blades 7. The lower end of the storage box 2 is fixedly connected to the feeding pipe 8. The lower end of the feeding pipe 8 passes through the mounting plate 1 and extends to the lower end of the mounting plate 1. The lower end of the first rotating rod 3 is fixedly connected to the second rotating rod 9. The second rotating rod 9 extends into the inside of the feeding pipe 8, and the rod wall of the second rotating rod 9 is fixedly connected to the threaded fan blade 10. An electric valve is fixedly installed on the lower end of the feeding pipe 8. When the drive motor 4 reverses the threaded fan blade 10, it will raise and cut the feed in the feeding pipe 8. When the drive motor 4 rotates the threaded fan blade 10 forward, it will lower the cut feed from the feeding pipe 8.

[0021] In use, the device is first fixed to the designated breeding area using the mounting plate 1. Then, different types of feed, such as concentrate and roughage, are filled into the symmetrically arranged storage boxes 2 through the filling tubes on one side of each of the two storage boxes 2. When feed needs to be added, the drive motor 4 fixed to the upper bracket of one of the storage boxes 2 is started. The output end of the drive motor 4 drives a first rotating rod 3 fixed to it to rotate. The first transmission wheel 5 on the upper wall of the first rotating rod 3 drives the other first rotating rod 3 to rotate synchronously through the first belt 6. The symmetrical cutting blades 7 on the lower walls of the two first rotating rods 3 rotate accordingly, cutting the blocks inside the storage box 2. The coarse, long, and thin materials are pre-cut. If feeding is required, the drive motor 4 is rotated forward, and the second rotating rod 9 at the lower end of the first rotating rod 3 rotates synchronously. The threaded fan blades 10 on the wall of the second rotating rod 9 convey the cut feed downward. At this time, the electric valve on the wall of the feed pipe 8 at the lower end of the storage box 2 is opened, and the feed falls into the mixing box 15 below through the feed pipe 8. If the feed in the feed pipe 8 becomes damp and clumps and becomes blocked, the drive motor 4 is rotated in reverse. The threaded fan blades 10 will convey the clumps of feed in the feed pipe 8 upward to the cutting blade 7 for secondary cutting and crushing. After crushing, the drive motor 4 is rotated forward again to complete the feeding.

[0022] Example 2: The technical solution of this example, which differs from that of Example 1, includes: the upper end of the storage box 2 on the side away from the drive motor 4 is rotatably connected to the transmission rod 11 via a bracket and bearing; a first bevel gear 12 is fixedly connected to one side of the transmission rod 11; the lower end of the first bevel gear 12 is meshed with a second bevel gear 13; the second bevel gear 13 is fixedly connected to the first rotating rod 3; a second transmission wheel 14 is fixedly connected to the other side of the transmission rod 11; the lower end of the mounting plate 1 is fixedly connected to the mixing box 15 with an open opening via a bracket; the wall of the mixing box 15 is rotatably connected to a third rotating rod 16 via a bearing; the middle wall of the third rotating rod 16 is fixedly connected to the mixing plate 17; and the wall of the third rotating rod 16 on the side away from the mixing plate 17 is fixedly connected to a third transmission wheel 18; the third transmission wheel 18 and the second transmission wheel 14 are jointly connected to the second belt 19; and the lower end of the mixing box 15 is fixedly connected to a symmetrically arranged flow pipe 20; the upper wall of the flow pipe 20 is fixedly connected to an electric valve; and a T-shaped plate for mounting and suspension is fixedly connected to one side of the outer wall of the mixing box 15.

[0023] In use, first complete the feed filling and drive motor 4 starting steps according to Example 1 to ensure the normal operation of the two first rotating rods 3 and the cutting blade 7, perform feed cutting pretreatment and initial conveying. When the first rotating rod 3 on the storage box 2 away from the drive motor 4 rotates, the second bevel gear 13 fixed to its rod wall drives the meshing first bevel gear 12 to rotate, and the transmission rod 11 fixed to the first bevel gear 12 rotates accordingly (the transmission rod 11 is connected to the upper end of the storage box 2 through a bracket and bearing). The second transmission wheel 14 on the other side of the transmission rod 11 drives the wall of the mixing box 15 through the second belt 19. The third rotating rod 16 connected to the bearing rotates, and the mixing plate 17 on the middle wall of the third rotating rod 16 rotates synchronously. At this time, different types of feed falling into the mixing box 15 from the two feed pipes 8 are fully mixed under the stirring action of the mixing plate 17 to avoid feed stratification. After the mixing is completed, the electric valve on the upper wall of the symmetrical flow pipe 20 at the lower end of the mixing box 15 is opened, and the mixed feed enters the feed replenishment box 23 below through the flow pipe 20. If it is necessary to adjust the installation position of the device, the T-shaped plate fixed on one side of the outer box wall of the mixing box 15 can be used to suspend or fix the device in a more suitable breeding area, thereby improving the installation flexibility of the device.

[0024] Example 3: The technical solution of this example, which differs from Example 2, includes: a stepper motor 21 fixedly connected to the lower end of the mixing box 15; a fixed rod 22 fixedly connected to the output end of the stepper motor 21; a circular feeding box 23 fixedly connected to the output end of the fixed rod 22; fixed plates 24 fixed to both sides of the lower end of the fixed rod 22; one side of the fixed plates 24 fixedly connected to the inner wall of the mixing box 15; several stirring plates 25 fixedly connected to the lower end of each fixed plate 24; a discharge port 26 penetrating through the lower end of the feeding box 23; and a positioning plate 27 fixedly connected to the outer wall of the feeding box 23 on the side of the discharge port 26. Plate 27 is rotatably connected to electric telescopic rod 28 via a rotary pull. The output end of electric telescopic rod 28 is rotatably connected to baffle 29 with timing sensor at the bottom via a rotating shaft. A connecting column 30 is fixedly connected to one side of the upper end of baffle 29. The upper end of connecting column 30 is rotatably connected to the lower end of feeding box 23 via a bearing. The lower ends of baffle 29 and discharge port 26 are in contact. The timing sensor on baffle 29 is wirelessly connected to electric telescopic rod 28. An annular groove 31 is opened on the outside of feeding box 23. Both sides of annular groove 31 are slidably connected to U-shaped rod 32 via slide rails and sliders. The upper end of U-shaped rod 32 is fixedly connected to the outer wall of mixing box 15.

[0025] When using, first complete the feed cutting, mixing and conveying according to the steps of Example 2, and ensure that the mixed feed enters the feeding box 23 smoothly through the flow pipe 20 (the feeding box 23 is a circular structure and is connected to the output end of the stepper motor 21 at the lower end of the mixing box 15 through the fixing rod 22). Start the stepper motor 21 at the lower end of the mixing box 15. The output end of the stepper motor 21 drives the fixing rod 22 to rotate, and the fixing rod 22 drives the feeding box 23 to rotate synchronously. The annular groove 31 on the outside of the feed box 23 is slidably connected to the U-shaped rod 32 via a slide rail and a slider (the upper end of the U-shaped rod 32 is fixed to the outer wall of the mixing box 15). This helps the feed box 23 maintain stability during rotation and prevents deviation. The fixing plates 24 fixed on both sides of the lower end of the fixing rod 22 rotate with the fixing rod 22 (the opposite side of the fixing plate 24 is fixed to the inner wall of the mixing box 15). Several stirring plates 25 at the lower end of the fixing plate 24 rotate synchronously, performing secondary stirring of the feed in the feed box 23 to further improve the mixing efficiency. To ensure uniform feed mixing, a baffle 29 is attached to the feed inlet 26 on one side of the lower end of the feeding box 23 (the bottom of the baffle 29 is equipped with a timing sensor, and the upper side is connected to the bearing at the lower end of the feeding box 23 via a connecting column 30). When the timing sensor detects that the amount of feed remaining in the trough is insufficient or the preset feeding time has been reached, it will wirelessly send a signal to the electric telescopic rod 28 (the electric telescopic rod 28 is rotatably connected to the positioning plate 27 on the outer wall of the feeding box 23 via a rotating shaft, and the output end is rotatably connected to the baffle 29 via a rotating shaft). Upon receiving a signal, the electric telescopic rod 28 starts, and its output end extends and retracts, causing the baffle 29 to rotate around the connecting column 30, opening the feed inlet 26. The feed in the feed box 23 falls precisely into the trough through the feed inlet 26. When the feed in the trough reaches the preset amount or the timer ends, the timer sensor sends a signal again, and the electric telescopic rod 28 drives the baffle 29 to reset, closing the feed inlet 26 and completing one precise feeding cycle. At the same time, the rotation angle of the feed box 23 can be adjusted by the stepper motor 21, and the feeding position can be dynamically adjusted according to the distribution of cattle and sheep to avoid feed waste or insufficient feeding in some areas.
