Technical Field

[0001] This utility model relates to the field of livestock breeding equipment technology, specifically to a pig pellet feeder with anti-arching properties. Background Technology

[0002] With the development of modern animal husbandry, large-scale and intensive pig farming has become the mainstream trend. Pelleted feed is widely used in pig production due to its advantages such as comprehensive nutrition, good palatability, and ease of mechanized transportation. As an important piece of equipment for achieving automatic feeding, the performance of the feeder directly affects feeding efficiency and feed utilization.

[0003] Most common pig pellet feeders currently use open or semi-closed structures. Although they can achieve continuous feed supply, they have obvious defects in practical applications. In particular, during the feeding process, pigs often use their noses to push the feed in the trough. This behavior not only causes a large amount of feed to be pushed out of the trough, resulting in serious feed waste, but also pollutes the ground, increases the cleaning workload of the farm, and affects environmental hygiene. Utility Model Content

[0004] The purpose of this utility model is to provide a pig pellet feeder that prevents feed from being pushed out of the trough by pigs, thereby solving the problem mentioned in the background art that the feed of the current pig pellet feeder is easily pushed out of the trough by pigs during use, resulting in waste and affecting environmental hygiene.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pig pellet feeder with anti-arching properties, comprising a storage hopper and a feeding trough. The bottom end of the storage hopper is connected to a conveying pipe, which extends to the top of the feeding trough. Support frames are provided on both sides of the top of the feeding trough.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4This utility model provides a technical solution: a pig pellet feeder with anti-arching properties, comprising a storage hopper 1 and a feeding trough 2. The two sides of the storage hopper 1 are fixedly connected to the rear outer wall of the feeding trough 2 via supports. A forward-inclined conveying pipe 3 is connected to the bottom of the storage hopper 1, extending above the feeding trough 2. Support frames 4 are provided on both sides of the top of the feeding trough 2. The support frames 4 are connected to the feeding trough 2 by bolts. Inclined baffles 5 are movably mounted on the support frames 4. An elastic limiting mechanism connected to the outer end of the baffles 5 is provided on the outer side of the support frames 4. Rotary guide wings 6 are installed at the four corners inside the feeding trough 2. Rolling friction wheels 7, which contact the inner wall of the bottom of the feeding trough 2, are connected to the bottom of the rotating guide wings 6. In this structure, the pelleted feed in the storage hopper 1 is conveyed to the top of the feeding trough 2 via the conveying pipe 3. The feed falls into the feeding trough 2 by gravity for the pigs to eat. When the pigs touch the feed in the feeding trough 2 with their noses or mouths, they are prone to arching behavior. At this time, the baffle plate 5 on the support frame 4 can form a certain enclosure for the feed, preventing the feed from being directly arched out of the feeding trough. At the same time, the baffle plate 5 is inclined and is movably installed by the support frame 4, so that it can swing slightly when the pigs touch it, but will not cause structural damage. The baffle plate 5 is elastically reset by the elastic limiting mechanism connected to the outside of the support frame 4 to ensure that it is always at a reasonable working angle. Meanwhile, the rotating guide vanes 6 installed at the four corners inside the feeding trough 2 can guide the feed during the falling process. The feed guide 6 plays a guiding and dispersing role, allowing the feed to flow more evenly to the bottom of the feeding trough 2, avoiding local accumulation. The rotating guide wing 6 can also roll on the inner wall of the bottom of the feeding trough 2 via the rolling friction wheel 7. This allows it to rotate flexibly and automatically reset when impacted by feed or touched by pigs, maintaining structural stability and guiding effect. Overall, it effectively prevents feed from being pushed out of the feeding trough by pigs, reducing feed waste, reducing the workload of cleaning the farm, improving feeding efficiency and environmental hygiene, and solving the problems of serious feed waste, large ground pollution, and inconvenient management caused by pigs pushing feed in the existing technology. Two sets of elastic limiting mechanisms are symmetrically arranged on the outer wall of the support frame 4. Each set of elastic limiting mechanisms includes a fixed sleeve 41, a movable shaft 42, and a tension spring 43. The bottom end of the support frame 4 is welded and fixed to the outer wall. The movable shaft 42 is movably inserted inside the fixed sleeve 41, and the top end of the movable shaft 42 is hinged to the corresponding connection point at the rear end of the baffle plate 5. The tension spring 43 is sleeved on the outside of the bottom end of the movable shaft 42. When the baffle plate 5 is subjected to the force of the pigs pushing the feed, its outer end swings, causing the movable shaft 42, which is hinged to it, to rotate and slightly displace inside the fixed sleeve 41. At this time, the tension spring 43 is stretched due to the movement of the movable shaft 42, accumulating elastic restoring force. When the external force disappears, the movable shaft 42 returns to its original position under the rebound action of the tension spring 43, thereby causing the baffle plate 5 to automatically return to the initial tilt angle, maintaining the normal working state of the feeder, and preventing the feed from being continuously pushed out of the trough.This design improves structural stability and protection. The feeding trough 2 has four notches at its interior corners, and a vertical shaft 8 is installed within each of these notches. The inner end of the rotating guide wing 6 has a connecting sleeve 9 fitted around the vertical shaft 8. Torsion springs 10 are fitted at both the upper and lower ends of the vertical shaft 8. When the rotating guide wing 6 is subjected to the impact of falling feed or the external force generated by pigs rooting in the feed, the entire connecting sleeve 9 rotates around the vertical shaft 8. During rotation, the torsion springs 10 are subjected to torque and accumulate elastic restoring force. When the external force disappears, the torsion springs 10 return to their original position. Spring 10 releases energy, causing the rotating guide wing 6 to automatically rotate back to its initial guiding angle, thus maintaining its stable guiding effect on the feed. The inner wall of the rotating guide wing 6 has a downward-sloping arc shape, and the inner wall of the rotating guide wing 6 is bonded with a flexible material edge. This structure allows the feed to slide down along the arc-shaped slope of the rotating guide wing 6 when the feed falls or when pigs arch the feed during feeding. This not only helps to evenly distribute the feed and avoid feed accumulation in certain areas, but also reduces the splashing and waste caused by feed directly impacting hard surfaces. In addition, the flexible material edge further enhances the safety of the structure and the smoothness of feed flow. It can effectively buffer the impact force between the feed and the rotating guide wing 6, reduce noise, reduce damage to feed particles, and prevent possible injuries to pigs when arching the feed. The top of the support frame 4 has a rectangular groove, and the two sides of the rear end of the baffle plate 5 are connected to the inner walls of the rectangular groove of the support frame 4 through a pivot. This structure allows the feed to slide down along the arc-shaped slope of the rotating guide wing 6 when pigs arch the feed in the feeding trough 2. When feeding, the feed baffle 5 will sway slightly due to the force applied, thus buffering the impact and preventing structural damage. The inner surface of the feed baffle 5 has multiple spaced-apart strip-shaped protrusions made of rubber and embedded in the inner surface. This structure provides additional friction when pigs feed and may nudge the feed baffle 5 with their noses or mouths, helping to prevent feed from slipping and also cushioning direct contact between the pigs and the feed baffle 5, reducing potential injury to the pigs.

[0019] Working principle: When using this anti-arching pig pellet feeder, the pellet feed is first added to the storage hopper 1. The feed is conveyed downwards through the conveying pipe 3 and falls into the feeding trough 2 by gravity. During this process, some feed contacts the inner wall of the rotating guide wing 6 and slides down its downward-sloping arc surface. When the pig begins to eat and touches the feed in the feeding trough 2 with its nose or mouth, the rotating guide wing 6 is subjected to force and rotates slightly around the vertical shaft 8 through the connecting sleeve 9. At the same time, the rolling friction wheel 7 connected at the bottom rotates slightly around the vertical shaft 8. The feed trough 2 rolls on the inner wall to maintain structural stability. When the pig's pushing force acts on the inner area of ​​the baffle plate 5, the baffle plate 5 swings slightly around the pivot at the top of the support frame 4 due to the force. At the same time, the outer end of the baffle plate 5 drives the movable shaft 42 to move in the fixed sleeve 41 through the hinge. The tension spring 43 is stretched and accumulates the reset potential energy. When the pig stops pushing the feed, under the rebound action of the tension spring 43, the movable shaft 42 drives the baffle plate 5 to return to the original tilt position, thus completing a series of operations.

[0020] 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.
