Description

Technical Field

[0001] This utility model relates to the field of livestock breeding equipment technology, specifically a dry and wet feeder for pigs that prevents feed leakage. Background Technology

[0002] With the development of modern animal husbandry, large-scale and intensive pig farming has become the mainstream trend. To improve feed utilization and feeding efficiency, dry and wet feeders are widely used in pig farming due to their ability to provide both dry feed and mixed moisture. These feeders can adjust the feed state according to the pigs' growth stages, thereby meeting the nutritional needs of different stages and improving the pigs' feeding enthusiasm and digestion.

[0003] While existing dry and wet feeders for pigs are relatively complete in terms of function, they still have certain shortcomings in actual use. In particular, during the process of feed falling from the outlet into the trough, due to the viscosity of the feed, it falls rapidly under the action of gravity and directly impacts the bottom or edge of the trough, which can easily cause feed splashing and leakage. This not only wastes feed resources but may also pollute the breeding environment and increase the workload of cleaning and maintenance. At the same time, the outlet structure of most feeders is a simple straight cylindrical design, lacking an effective buffer device, which cannot effectively slow down the speed and impact of the feed falling, further aggravating the problem of feed leakage. Utility Model Content

[0004] The purpose of this utility model is to provide a leak-proof dry and wet feeder for pigs, in order to solve the problems mentioned in the background art, such as the unreasonable design of the discharge port structure of current dry and wet feeders for pigs, which leads to large impact force when feed falls, and easy splashing and leakage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a leak-proof dry and wet feeder for pigs, comprising a feeder body, a feed outlet pipe at the bottom end of the feeder body, a feed buffer ring detachably installed on the outside of the feed outlet pipe, an inner support ring embedded inside the feed buffer ring, multiple dynamic guide vanes and solid guide vanes respectively provided at the upper and lower ends of the inner support ring, and a composite guide structure composed of multiple annular guide ribs and strip guide ribs on the inner wall at the bottom end of the feed buffer ring.

[0006] Preferably, both the dynamic guide vane and the solid guide vane are circumferentially and uniformly distributed along the inner wall of the inner support ring, and the inner end of the dynamic guide vane is connected to the inner wall of the buffer ring through an elastic element.

[0007] Preferably, the bottom end of the discharge pipe has a trumpet-shaped structure, and the annular guide ribs and strip guide ribs are alternately distributed on the inner wall of the bottom end of the discharge pipe.

[0008] Preferably, connecting blocks are fixed on both sides of the discharge pipe, and fixed sleeves are provided on both outer walls of the top of the slowing ring. A coupling passes through the inside of the fixed sleeve, and the upper end of the coupling is inserted into the mating hole opened at the outer end of the connecting block and fixed by bolts.

[0009] Preferably, a compression spring is sleeved on the outside of the bottom end of the coupling, and the upper and lower ends of the compression spring are respectively connected to the bottom end of the fixed sleeve and the inner side of the end block of the bottom end of the coupling.

[0010] Preferably, both the dynamic guide vane and the solid guide vane are inclinedly distributed inside the inner support ring, and the lower ends of both the dynamic guide vane and the solid guide vane are located at the center of the buffer ring.

[0011] Compared with existing technologies, the beneficial effects of this utility model are: this leak-proof dry and wet feeder for pigs effectively reduces the impact force of falling feed, lowers the risk of splashing and leakage, has a simple structure, is highly practical, improves feed utilization, and reduces environmental pollution. This leak-proof dry and wet feeder for pigs incorporates a removable feed buffer ring in the discharge pipe. The buffer ring, through the combined design of internal dynamic guide vanes and elastic components, achieves flexible adjustment of feed flow rate. Combined with the multiple guiding and buffering effects of solid guide vanes, annular guide ribs, and strip guide ribs, it effectively controls the feed's falling trajectory, preventing splashing and spillage, thereby improving the stability of the overall feeding process and environmental cleanliness.

[0016] 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.

[0017] Please see Figure 1-3This utility model provides a technical solution: a leak-proof dry / wet feeder for pigs, including a feeder body 1, a feed pipe 2 at the bottom of the feeder body 1, a feed-relieving ring 3 detachably installed on the outside of the feed pipe 2, an inner support ring 4 embedded inside the feed-relieving ring 3, and multiple dynamic guide plates 401 and solid guide plates 402 respectively provided at the upper and lower ends of the inner support ring 4. Furthermore, a composite guide structure composed of multiple annular guide ribs 301 and strip guide ribs 302 is provided on the inner wall at the bottom of the feed-relieving ring 3. When feed is conveyed downwards from the feed pipe 2 at the bottom of the feeder body 1 and passes through the feed-relieving ring 3, the dynamic guide plates 401 and solid guide plates 402 work together at the upper and lower ends of the inner support ring 4. 1. Under the impact of falling feed, a flexible oscillation is generated, forming a dynamic adjustment of the feed flow speed. At the same time, the solid guide plate 402 stably guides the feed flow direction, making the feed evenly distributed and slowing down its falling speed. Meanwhile, the annular guide rib 301 and strip guide rib 302 in the composite guide structure on the inner wall of the bottom end of the slowing ring 3 further divert and buffer the feed in multiple directions. The annular guide rib 301 enhances the flow resistance of the feed in the circumferential direction, while the strip guide rib 302 applies a linear guiding effect to the feed. The two work together to effectively reduce the kinetic energy of the falling feed and avoid splashing or leakage caused by gravity impact on the feed trough. This solves the defects of the existing straight-cylinder discharge port structure, which is prone to feed splashing, leakage and environmental pollution. Both the dynamic guide vane 401 and the solid guide vane 402 are circumferentially and evenly distributed along the inner wall of the inner support ring 4. The inner end of the dynamic guide vane 401 is connected to the inner wall of the buffer ring 3 through the elastic element 403. In this structure, the dynamic guide vane 401 undergoes elastic deformation and flexible oscillation under the impact force of falling feed through the elastic element 403, thereby dynamically adjusting the feed flow rate and playing a buffering and deceleration role. The solid guide vane 402 maintains a fixed guiding state and works in conjunction with the dynamic guide vane 401 to ensure that the feed is evenly distributed circumferentially and flows stably in the set direction. The design of both being circumferentially evenly distributed ensures the balance of feed flow, avoids excessively fast local flow rates or blockages, and further reduces feed splashing and To mitigate the risk of feed leakage and enhance the continuity and controllability of the feeding process, the bottom of the discharge pipe 2 features a trumpet-shaped structure. Annular guide ribs 301 and strip guide ribs 302 are alternately distributed on the inner wall of the bottom of the discharge pipe 2. This trumpet-shaped structure effectively expands the flow cross-section of the falling feed, reducing the feed velocity per unit area and thus mitigating the impact of the feed on the trough below. Simultaneously, the alternating distribution of annular guide ribs 301 and strip guide ribs 302 forms a multi-directional composite flow surface. The annular guide ribs 301 guide the feed to diffuse circumferentially, while the strip guide ribs 302 apply a linear diversion effect to the feed. The combined effect of these two components makes the feed distribution more uniform and the flow more stable. Connecting blocks 5 are welded and fixed to both sides of the discharge pipe 2.Furthermore, fixed sleeves 7 are welded and fixed to both outer walls of the top two sides of the feed-retarding ring 3. A coupling 6 passes through the inside of the fixed sleeve 7. The upper end of the coupling 6 is inserted into the mating hole opened at the outer end of the connecting block 5 and fixed with bolts. A compression spring 8 is sleeved on the outside of the bottom end of the coupling 6, and the upper and lower ends of the compression spring 8 are respectively connected to the bottom end of the fixed sleeve 7 and the inner side of the end block at the bottom end of the coupling 6. When the feed-retarding ring 3 is subjected to the impact force of falling feed, the coupling 6 provides support and positioning for the feed-retarding ring 3 through the connection structure between the connecting block 5 and the fixed sleeve 7, ensuring its installation stability and operational reliability. At the same time, the compression spring 8 can generate an elastic buffering effect during the force process, absorbing shock. The dynamic energy further enhances the stability of the entire slowing ring 3 during operation. Furthermore, this structure facilitates disassembly and maintenance, allowing for quick assembly and separation between the slowing ring 3 and the discharge pipe 2 via bolt fixing, thus improving equipment cleaning efficiency. Both the dynamic guide vane 401 and the solid guide vane 402 are inclinedly distributed inside the inner support ring 4, with the lower ends of both vanes located at the center of the slowing ring 3. This structure allows the feed to flow naturally towards the discharge center area under gravity along the inclined direction of the guide vanes, forming a concentrated and stable discharge path to prevent splashing and leakage caused by turbulent flow or uneven distribution.

[0018] Working principle: When using this leak-proof dry and wet feeder for pigs, the feed first flows downward from the feeder body 1 through the discharge pipe 2 and enters the inner support ring 4 area inside the slowing ring 3. The feed then passes through the vertically distributed dynamic guide vanes 401 and solid guide vanes 402. Under the impact of the feed, the dynamic guide vanes 401 oscillate flexibly through the elastic element 403, and together with the solid guide vanes 402, guide the feed to flow towards the center of the slowing ring 3 in an inclined direction. Subsequently, the feed continues to flow downward and enters the annular guide ribs 301 and strip guide ribs 302 on the inner wall of the bottom of the slowing ring 3. In the composite flow guiding structure area, the feed is subjected to multi-directional diversion and guidance by the annular flow guiding ribs 301 and the strip flow guiding ribs 302, which further adjusts the flow direction and tends to stabilize. At the same time, the trumpet-shaped structure at the bottom of the discharge pipe 2 expands the feed flow cross section, making the feed more evenly dispersed and falling. Throughout the process, the slowing ring sleeve 3 cooperates with the coupling 6 through the fixed sleeves 7 on both sides. The upper end of the coupling 6 is inserted into the docking hole of the connecting block 5 and fixedly connected by bolts. The compression spring 8 elastically expands and contracts with the pressure generated by the feed flow, maintaining the stability of the slowing ring sleeve 3, thereby completing a series of tasks.

[0019] 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.
