Description

Technical Field

[0001] This utility model relates to the field of breeding equipment technology, and in particular to a feeding device for piglet breeding. Background Technology

[0002] The feeding device for piglet rearing is a piece of equipment specifically designed for piglet rearing. Through its innovative structure and intelligent control system, it achieves precise feeding and uniform distribution of feed, effectively preventing piglets from fighting for food and ensuring that each piglet receives sufficient nutrition. At the same time, the device can reduce manual labor intensity, reduce feed waste, improve feeding efficiency, meet the needs of different breeding scenarios in large-scale livestock and poultry farming, and provide strong support for the healthy growth of piglets and the improvement of breeding efficiency.

[0003] A search revealed a utility model patent with publication number CN221670672U, which discloses a feeding device for piglet rearing. The device includes a feeding plate with a first annular groove. A rotating platform is spaced above the feeding plate, and a second annular groove is located at the top of the rotating platform. An annular conveyor belt of a size adapted to the second annular groove is located within the second annular groove. Storage bins are spaced above the rotating platform and connected to the rotating platform via multiple second support columns. Each storage bin has a storage cavity, and multiple discharge pipes are located at the bottom of the storage cavity. Each discharge pipe is equipped with a solenoid valve, and its outlet faces the annular conveyor belt. The rotating platform has multiple openings communicating with the second annular groove, and multiple cylinders corresponding to these openings. This device addresses the problem of larger piglets competing for food, causing smaller piglets to have difficulty eating or consume less food, thus hindering their normal growth.

[0004] While the aforementioned patent utilizes a solenoid valve to discharge feed from the storage hopper to a circular conveyor belt via a discharge pipe, and then extends the piston end of a cylinder to block the second circular groove, allowing feed on the conveyor belt to fall from the opening into the first circular groove, the extension and retraction of different cylinders facilitates adjustment of the feed's position from the conveyor belt into the first circular groove, thus distributing the feed more effectively. Furthermore, placing the feed in the first circular groove allows smaller piglets to eat nearby, even if they compete for food, increasing their feeding range and preventing them from eating less. However, this presents a problem: inconvenient feed tray replacement. Common piglet feeding devices often have complex connection structures between the feed tray and the main body, using welding and bolting to ensure a tight connection. When the feed tray wears out, is damaged, or needs frequent replacement for hygiene, workers must use various specialized tools and spend considerable time and effort disassembling and reassembling it. Therefore, this paper proposes a feeding device for piglet farming to address these issues. Utility Model Content

Detailed Implementation

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] A feeding device for piglet rearing, referring to Figures 1 to 3 The system includes two supports 1, with a fixing mechanism 2 fixedly connected to adjacent sides of the two supports 1. The fixing mechanism 2 connects the supports 1 to subsequent components and is the core structure for quick installation and disassembly of the feed trough 3. The feed trough 3 is fixedly connected to the outside of the fixing mechanism 2. The shape of the feed trough 3 is designed according to the piglets' feeding habits, with moderate depth and width to facilitate comfortable feeding for the piglets and reduce feed waste. A fixing frame 4 is fixedly connected to adjacent sides of the two supports 1. It is made of multiple metal rods welded together to form a sturdy frame structure. A feed storage tank 5 is fixedly connected to the inner wall of the fixing frame 4. The feed storage tank 5 is used to store the piglets' feed. It adopts a large-capacity cylindrical design, which can hold more feed and reduce the frequency of feeding.

[0021] A top cover 6 is fixedly connected to the top of the feed tank 5. The main function of the top cover 6 is to seal the feed tank 5, further enhancing its airtightness and preventing external dust, debris, and insects from entering the tank and contaminating the feed. An opening and closing mechanism 7 is fixedly connected to the rear side of the top cover 6; through mechanical transmission, the opening and closing of the top cover 6 is easier and less strenuous, improving the work efficiency of the farmers. The fixing mechanism 2 includes two fixing blocks 21, with the far sides of the two fixing blocks 21 fixedly connected to the near sides of the bottom of the two supports 1, ensuring that the fixing mechanism 2 can stably withstand the force from the feed trough 3 when fixing and releasing it, without loosening or falling off.

[0022] Multiple connecting posts 22 are fixedly connected to the opposite sides of the material basin 3. When installing the material basin 3, the connecting posts 22 are inserted into the fixing blocks 21 to fix the material basin 3. Two trapezoidal limiting blocks 23 are slidably connected to the inner walls of the two fixing blocks 21. When the trapezoidal limiting blocks 23 slide into the slots of the connecting posts 22, they can tightly lock the connecting posts 22, firmly fixing the material basin 3 to the fixing blocks 21; when the trapezoidal limiting blocks 23 slide out of the slots, the connecting posts 22 are no longer restricted, and the material basin 3 is released. Connecting strips 24 are fixedly connected to the opposite sides of the multiple trapezoidal limiting blocks 23. The connecting strips 24 serve to transmit power. Moving strips 25 are slidably connected to the inner walls of the two fixing blocks 21. The moving strips 25 slide in the slides on the inner walls of the fixing blocks 21, and drive the trapezoidal limiting blocks 23 to extend and retract through the connecting strips 24.

[0023] A connecting assembly 26 is fixedly connected to the outside of the two moving bars 25. This provides an operating interface for the farmers to easily control the moving bars 25. The connecting assembly 26 includes multiple moving shafts 261, with the adjacent sides of the multiple moving shafts 261 fixedly connected to the front and rear sides of the two moving bars 25. The moving shafts 261 are made of high-strength alloy steel, possessing high strength and wear resistance, capable of withstanding large torque and tensile forces, ensuring the reliability and stability of the connecting assembly 26. Control bars 262 are fixedly connected to the distant sides of the multiple moving shafts 261. By pulling the control bars 262, the moving shafts 261 and the moving bars 25 can be moved, thereby controlling the extension and retraction of the trapezoidal limit block 23, realizing the installation and removal of the feed tray 3. Two damping posts 263 are fixedly connected to the bottom ends of the two moving bars 25. When the moving bar 25 slides to its limit position, the damping posts 263 contact the inner wall of the fixed block 21, generating damping force, causing the moving bar 25 to stop smoothly.

[0024] Multiple trapezoidal limiting blocks 23 are fixedly connected to the inner walls of each trapezoidal limiting block 23. The guide rods 264 provide precise guidance for the sliding of the trapezoidal limiting blocks 23, ensuring that the trapezoidal limiting blocks 23 do not tilt or deviate during movement. Protective frames 265 are fixedly connected to adjacent sides of the two supports 1. The protective frames 265 are located above the feed trough 3, and their main function is to prevent piglets from pushing feed out of the feed trough 3 while eating, reducing feed waste. Multiple connecting rods 266 are rotatably connected to the inner wall of the bottom end of the protective frame 265. When the feed trough 3 is installed or removed, the connecting rods 266 can rotate around the connection point with the protective frame 265, providing auxiliary support and stabilizing the feed trough 3.

[0025] Multiple control discs 267 are fixedly connected to the inner wall of the material basin 3. The surface of the control discs 267 is smooth and easy to clean, and they are also used to control the subsequent components to complete the fixing. The bottom of each control disc 267 is fixedly connected to a limit rod 268. When the connecting rod 266 is inserted into the material basin 3, the limit rod 268 fixes the connecting rod 266. The top of each limit rod 268 is fitted with a spring 269. When the connecting rod 266 is released, the control disc 267 is pulled. The control disc 267 drives the limit rod 268 to move, and the spring 269 is stretched. After completion, the spring 269 drives the limit rod 268 to reset and wait for the next operation.

[0026] Reference Figure 4 and Figure 6 The opening and closing mechanism 7 includes two connecting blocks 71. The front sides of the two connecting blocks 71 are fixedly connected to the rear side of the top cover 6. The inner walls of the two connecting blocks 71 are rotatably connected to a rotating shaft 72. This rotatable connection ensures that the opening and closing mechanism 7 can achieve smooth and stable rotational movement when opening and closing the top cover 6. A connecting block 73 is fixedly connected to the outside of the rotating shaft 72, which serves to support the rotation of the rotating shaft 72 and transmit the motion to other components. A rotating shaft 74 is fixedly connected to the inner wall of the bottom end of the connecting block 73. The connection between the rotating shaft 74 and the connecting block 73 is similar to the connection between the rotating shaft 72 and the connecting block 71, and is also installed using high-precision bearings. A connecting block 75 is rotatably connected to the outside of the rotating shaft 74. The connecting block 75 moves under the drive of the connecting block 73 through its rotatable connection with the rotating shaft 74.

[0027] A damping column 76 is fixedly connected to the front bottom of connecting block 3 75. During the opening or closing of the top cover 6, the damping column 76 absorbs the impact and inertial forces during movement, slowing down the movement speed of the top cover 6 and allowing it to open and close smoothly. A sealing ring 77 is fixedly connected to the inner wall of the top cover 6. The sealing ring 77 fits tightly against the top of the storage tank 5, forming a sealed space to prevent external dust, moisture, insects, etc., from entering the storage tank 5. Multiple damping rods 78 are fixedly connected to the inner wall of the top of the top of the top cover 6. When the top cover 6 is closed, the bottom end of the damping rod 78 contacts the top of the storage tank 5. As the top cover 6 descends, the damping rod 78 is compressed. A buffer pad 79 is fixedly connected to the bottom end of the multiple damping rods 78. When the damping rod 78 is compressed, the buffer pad 79 first contacts the top of the storage tank 5, absorbing the impact force through its own elastic deformation, further reducing the vibration and noise when the top cover 6 is closed.

[0028] Support blocks 701 are fixedly connected to the bottom ends of both sides of the top cover 6, providing auxiliary support during the opening and closing of the top cover 6. Damping rods 702 are rotatably connected to the inner walls of the bottom ends of both support blocks 701. When the top cover 6 opens, the damping rods 702 are stretched, and the hydraulic oil flowing inside generates resistance, limiting the opening speed of the top cover 6. When the top cover 6 closes, the damping rods 702 are compressed, and the resistance of the hydraulic oil similarly slows down the closing speed of the top cover 6. Support blocks 703 are rotatably connected to the outer bottom ends of both damping rods 702. Support blocks 703 provide a stable connection point for the damping rods 702, bearing the force from the damping rods 702 during the opening and closing of the top cover 6 and transmitting it to the fixed frame 4, ensuring the stability of the entire opening and closing mechanism 7.

[0029] Reference Figure 5 and Figure 7 Multiple trapezoidal limiting blocks 23 are externally fixedly connected to the outer inner wall of multiple connecting columns 22 on opposite sides. When the trapezoidal limiting blocks 23 slide into the slots of the connecting columns 22 along the guide rod 264, the trapezoidal structure will tighten due to the relationship between the direction of force and the angle of the inclined plane, firmly fixing the connecting columns 22 when the feed trough 3 is subjected to external force when piglets eat or daily vibration. Multiple connecting strips 24 are fixedly connected to the adjacent sides of two moving strips 25 on opposite sides. When the farmer pulls the control strip 262, the moving strip 25 slides in the slide in the inner wall of the fixed block 21, and the connecting strip 24 accurately transmits the linear movement of the moving strip 25 to the trapezoidal limiting blocks 23. Multiple limiting rods 268 are externally fixed to the inner wall of the feed trough 3. When piglets collide with the feed trough 3 during feeding, or when the feed trough 3 is subjected to force due to uneven feed weight distribution, the limiting rods 268 will contact the inner wall of the protective frame 265 to prevent the feed trough 3 from shaking or shifting excessively.

[0030] Multiple connecting rods 266 are fixedly connected at their bottom ends to the inner wall of the material basin 3. When the material basin 3 is installed or disassembled, the connecting rods 266 can rotate around the connection point with the protective frame 265, providing auxiliary support and guidance. After the material basin 3 is installed in place, the connecting rods 266, the material basin 3, and the protective frame 265 form a triangular structure. Multiple limiting rods 268 are externally fixedly connected to the inner wall of the bottom end of the multiple connecting rods 266. The limiting rods 268 pass through the reserved holes in the inner wall of the bottom end of the connecting rods 266, and the two fit tightly together. This further strengthens the structural connection between the limiting rods 268 and the material basin 3 and the protective frame 265. Multiple springs 269 are externally slidably connected to the inner wall of the material basin 3. Two fixing blocks 21 are fixedly connected to the outside of the material basin 3 on their adjacent sides, serving as the basic carrier of the fixing mechanism 2, organically combining the various components to form a complete fixing system.

[0031] Multiple damping columns 263 are fixedly connected at their bottom ends to the inner walls of the bottom ends of two fixed blocks 21. When the moving strip 25 slides too fast, the hydraulic oil in the damping column 263 is obstructed through the small damping holes, generating greater resistance and slowing down the speed of the moving strip 25. Multiple guide rods 264 are fixedly connected at their bottom ends to the inner walls of the bottom ends of two fixed blocks 21. When the trapezoidal limit block 23 moves under the action of the connecting strip 24, the guide rods 264 provide precise guidance for the sliding of the trapezoidal limit block 23. Two control strips 262 are slidably connected to the outside of the fixed blocks 21 on their adjacent sides. When the farmer pulls the control strip 262, the control strip 262 slides in the slide rail outside the fixed block 21, driving the moving strip 25 to slide on the inner wall of the fixed block 21 through the moving shaft 261, thereby controlling the extension and retraction of the trapezoidal limit block 23.

[0032] A groove is provided on the rear side of the storage tank 5. The front side of the connecting block 3 75 is slidably connected to the rear inner wall of the storage tank 5. Under the transmission of the opening and closing mechanism 7, the slider of the connecting block 3 75 slides in the groove, converting the rotational motion of the connecting block 2 73 into linear motion, thereby pushing the top cover 6 to open and close. The bottom end of the damping column 2 76 is fixedly connected to the inner wall of the storage tank 5. During the opening or closing process of the top cover 6, the damping column 2 76 can absorb the impact force and inertial force of the movement of the connecting block 3 75, slowing down the opening and closing speed of the top cover 6 and making its operation smooth.

[0033] The inner wall of the sealing ring 77 is fixedly connected to the outer top of the storage tank 5. When the top cover 6 is closed, under its own weight and the action of the installation structure, the top cover 6 presses down on the sealing ring 77. The sealing ring 77 undergoes elastic deformation under compression, tightly filling the gap between the top cover 6 and the storage tank 5, forming a sealed space. The bottom end of the buffer pad 79 is fixedly connected to the top of the storage tank 5. When the top cover 6 is closed, the buffer pad 79 first contacts the top cover 6. Under the pressure of the top cover 6, the buffer pad 79 absorbs the impact force when the top cover 6 closes through its own elastic deformation, converting the impact force into its own elastic potential energy, and then slowly releasing it. The bottom ends of the two support blocks 703 are fixedly connected to the top of the fixing frame 4. The support blocks 703 are connected to the fixing frame 4 by welding or bolt fastening, providing a stable installation base and support point for the damping rod 702.

[0034] The implementation principle of this application embodiment is as follows: When it is necessary to install the material basin 3, push the control bar 262, the control bar 262 drives the moving shaft 261 to move, and then the moving bar 25 slides on the inner wall of the fixed block 21. The moving bar 25 drives the trapezoidal limiting block 23 to slide along the guide rod 264 in the fixed block 21 through the connecting bar 24, so that the trapezoidal limiting block 23 moves away from the connecting post 22. At this time, the connecting post 22 on the material basin 3 can be aligned with the fixed block 21 and inserted. After insertion, push the control bar 262 in the opposite direction, the moving bar 25 drives the trapezoidal limiting block 23 to slide in the opposite direction through the connecting bar 24, so that the trapezoidal limiting block 23 is stuck into the outer inner wall of the connecting post 22, thereby fixing the connecting post 22 and completing the installation and fixing of the material basin 3.

[0035] Meanwhile, the connecting rod 266 on the protective frame 265 is inserted into the inner wall of the feed basin 3. After the connecting rod 266 is fixed to the inner wall of the feed basin 3, the limiting rod 268 fixes the connecting rod 266, which plays a stabilizing role after the feed basin 3 is installed. This achieves the effect of quick, convenient, stable and reliable installation or replacement of the feed basin 3, making it easier for farmers to clean, maintain and replace the feed basin 3, improving the efficiency of breeding work and ensuring the hygiene of piglets' feeding.

[0036] When the top cover 6 needs to be opened, an external force is applied to make connecting block 71 rotate around shaft 72. Connecting block 71 drives connecting block 73 to rotate around shaft 72. Connecting block 73 drives connecting block 75 to slide in the groove on the rear side of storage tank 5 through shaft 74. During the movement of connecting block 75, the damping column 76 at the bottom interacts with the inner wall of storage tank 5, which plays a role in buffering and stabilizing the movement trajectory. At the same time, when the top cover 6 moves, the support blocks 701 on the left and right sides pull the damping rod 702, causing the damping rod 702 to rotate around support block 703 to assist in supporting the top cover 6 and making the top cover 6 rise smoothly. During this process, the damping rod 78 and buffer pad 79 on the inner wall of the top cover 6 contact the top of storage tank 5 to reduce the impact force when closing, while the sealing ring 77 ensures the sealing between the top cover 6 and storage tank 5, thereby achieving a smooth, labor-saving and well-sealed opening and closing effect of the top cover 6.

[0037] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
