Description

Technical Field

[0001] This utility model relates to the technical field of feed dispensing devices, and in particular to a feed dispensing device for pig feeding. Background Technology

[0002] In modern pig farms, liquid feed is widely used in piglet nursery and sick pig care due to its palatability and easy digestibility. Traditional liquid feed dispensing devices mostly use mechanical valves or fixed openings to control the flow rate, but such structures have significant drawbacks: First, traditional valves and pipe interfaces are mostly in rigid contact, and long-term flushing by liquid feed can easily cause wear on the sealing surface, leading to leakage problems, especially in scenarios with particulate or viscous feed, where the failure frequency is even higher. Second, mechanical valves require manual operation and cannot automatically open and close according to the liquid level in the feed trough, requiring frequent monitoring by farm staff, which is costly and prone to feed overflow or insufficient supply due to operational delays.

[0003] To address the aforementioned issues, some existing technologies attempt to achieve automatic flow control through float structures, but they generally suffer from the following limitations: floats made of a single material are prone to failure; floats made entirely of plastic or metal either suffer from insufficient buoyancy due to density mismatch or seal failure due to deformation caused by long-term immersion. In view of this, we propose a feed dispensing device for pig farming. Utility Model Content

[0004] The main purpose of this utility model is to provide a feed dispensing device for pig feeding, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A feed dispensing device for pig feeding includes a storage tank for holding liquid feed and a feed trough disposed below the storage tank. The lower part of the storage tank is connected to a discharge pipe through a conical cylinder, and the lower part of the discharge pipe is coaxially connected to a thick cylinder, which contains a float valve that acts as a valve.

[0007] The inner diameter of the coarse cylinder and the outer diameter of the float valve are larger than the inner diameter of the discharge pipe, while the outer diameter of the float valve is smaller than the inner diameter of the coarse cylinder. A gap is reserved between the bottom surface of the coarse cylinder and the inner bottom surface of the feed trough for the passage of liquid feed.

[0008] Preferably, the float valve includes an inner supporting hollow ball and a rubber ball surrounding the inner supporting hollow ball, with a hollow interlayer reserved between the spherical outer wall of the inner supporting hollow ball and the spherical inner wall of the rubber ball.

[0009] Preferably, the lower edge of the feed inlet at the top of the coarse cylinder is provided with an annular sealing groove that fits against the outer wall of the float valve, and the sealing surface of the annular sealing groove adopts a different gradient surface layer design.

[0010] Preferably, a cone with its pointed tip facing upward is fixedly installed on the inner bottom surface of the material trough, and the diameter of the cone is larger than the outer diameter of the coarse cylinder.

[0011] Preferably, a top cover is detachably connected to the upper opening of the storage tank, and a handle is fixedly installed on the top of the top cover.

[0012] Preferably, the material trough is detachably installed below the storage tank via a support frame.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model employs a dual-structure float valve to improve control reliability. The float valve uses a composite structure of an inner supporting hollow ball and an outer rubber ball. The inner hard material provides structural support, while the outer soft rubber ball achieves a tight seal. The design of the inner layer being lower than the outer layer allows the liquid buoyancy to act preferentially on the outer rubber ball, improving the sensitivity of the float's opening and closing. The hollow interlayer reduces the overall weight, optimizes buoyancy characteristics, and ensures that the float responds quickly to changes in feed level, avoiding feeding delays or spills.

[0015] 2. This utility model adopts an annular sealing groove gradient surface layer to enhance the sealing effect. The sealing surface of the annular sealing groove adopts a different gradient surface layer design, combined with the soft material of the rubber ball, to form multiple sealing barriers. The inner support structure stabilizes the sealing base, and the outer flexible material adapts to the deformation of the ball, effectively filling tiny gaps and reducing liquid feed leakage. It is especially suitable for the long-term sealing needs of pig farms in high humidity environments.

[0016] 3. In this utility model, the outer wall of the rubber ball surrounding the float valve is treated with an anti-stick coating, which can effectively prevent liquid feed from sticking and clumping, avoid float jamming or sealing failure caused by material residue, reduce the frequency of manual maintenance, and extend the service life of the equipment. It is especially suitable for liquid feed containing easily sticky components such as oil and protein.

[0017] 4. This utility model uses a combination of a conical cylinder and a coarse cylinder to optimize fluid characteristics. The bottom of the storage tank is connected to the discharge pipe through a conical cylinder. The conical structure can guide the liquid feed to flow smoothly into the discharge pipe, reducing dead corners and residues. The flared design of the coarse cylinder, with an inner diameter larger than that of the discharge pipe, reduces the feed flow rate and avoids wear on the sealing surface caused by the impact of the float valve due to excessive flow rate. At the same time, it provides sufficient vertical movement space for the float, ensuring a smooth and impact-free opening and closing process.

[0018] 5. The cone-shaped head on the bottom surface of the feed trough in this utility model can disperse the impact flow of liquid feed, avoid concentrated feeding to form vortices or splashes, and make the feed evenly distributed in the feed trough. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figures 1-4 As shown, a feed dispensing device for pig feeding includes a storage tank 1, a conical cylinder 5, a discharge pipe 6, a coarse cylinder 7, a feed trough 8, and a float valve 10. The components are connected by pipes or structural connections to form a complete liquid feed delivery and control system.

[0026] The storage tank 1 is used to store liquid feed. The top opening is detachably connected to the top cover 3. The top cover 3 is fixedly connected to the handle 4 for easy feeding and cleaning. The bottom of the storage tank 1 is connected to the discharge pipe 6 through a conical cylinder 5. The conical structure can guide the feed to flow smoothly into the discharge pipe 6.

[0027] The coarse cylinder 7 is coaxially connected below the discharge pipe 6. The inner diameter of the storage tank 1 is larger than that of the discharge pipe 6, forming a flared structure to provide room for the float valve 10 to move. A gap is reserved between the bottom surface of the storage tank 1 and the inner bottom surface of the feed trough 8 as the final outlet of the liquid feed.

[0028] The feed trough 8 is detachably installed below the feed tank 1 via the support frame 2. It is used to receive feed for pigs to eat. The inner bottom surface is fixed with a cone 9, the tip of which faces upward. The cone 9 has a diameter larger than the outer diameter of the thick cylinder 7. It is used to break up liquid flow interference, prevent feed from concentrating and impacting the bottom of the feed trough 8 to form a vortex, and disperse the flow.

[0029] As a core control component, the float valve 10 adopts a composite structure of an inner supporting hollow ball 12 and an outer rubber ball 13. The inner supporting hollow ball 12 is made of rigid plastic to provide structural strength and serves as an inner skeleton to support the outer rubber ball 13, ensuring the overall shape stability of the float valve 10. Its density is designed to be less than that of liquid feed, and it has a hollow structure to ensure buoyancy drive. The inner supporting hollow ball 12 is located below the rubber ball 13 in the liquid, so that the buoyancy of the feed acts on the outer rubber ball 13 first, improving the opening and closing sensitivity.

[0030] The rubber ball 13 is made of soft, food-grade sealing material. The outer wall of the rubber ball 13 fits into the annular sealing groove 11 of the coarse cylinder 7. A hollow sandwich 14 is formed between the inner wall of the rubber ball 13 and the inner supporting hollow ball 12 to reduce the overall weight and optimize buoyancy characteristics. The outer wall of the rubber ball 13 is coated with an anti-stick coating, which is specifically made of polytetrafluoroethylene to prevent liquid feed from adhering and clumping, affecting the sealing effect and the movement of the float.

[0031] An annular sealing groove 11, concentrically matched with the outer wall of the float valve 10, is provided at the lower edge of the feed inlet at the top of the coarse cylinder 7. The annular sealing groove 11 adopts different gradient surface layers. The side of the annular sealing groove 11 closer to the discharge pipe 6 is harder to support the sealing structure, while the side of the annular sealing groove 11 further away from the discharge pipe 6 is softer to accommodate the deformation of the rubber ball 13. Together with the soft material of the rubber ball 13, multiple sealing barriers are formed to reduce feed leakage. The inner wall of the annular sealing groove 11 needs to be cleaned regularly to prevent feed residue from hardening. This can be achieved by disassembling the coarse cylinder 7.

[0032] The working process of the feed dispensing device for pig farming is as follows:

[0033] First, feeding: Liquid feed in storage tank 1 flows into coarse cylinder 7 through conical cylinder 5 and discharge pipe 6. As the inner diameter of coarse cylinder 7 increases, the flow rate decreases. When the feed liquid level does not touch float valve 10, it flows freely into feed trough 8 through the gap between coarse cylinder 7 and feed trough 8 for pigs to eat.

[0034] Second, automatic shut-off: When the feed liquid level in the feed trough 8 rises to below the coarse cylinder 7, the buoyancy acts on the outer layer of the rubber ball 13, pushing the float valve 10 to move upward. The outer wall of the rubber ball 13 is embedded in the annular sealing groove 11 of the coarse cylinder 7. By using the gradient sealing surface and the soft material to adhere to the surface, the feed continues to flow in, avoiding overflow.

[0035] Third, liquid level drop and reset: When pigs eat, the liquid level in feed trough 8 drops, the buoyancy of float valve 10 decreases, and it falls back under its own gravity. The gap between coarse cylinder 7 and feed trough 8 reopens, and feed flows in again, realizing automatic feeding cycle.

[0036] It should be added that the storage tank 1, the conical cylinder 5, the discharge pipe 6, and the coarse cylinder 7 are all made of corrosion-resistant plastic to meet the feed hygiene requirements. The inner support hollow ball 12 and the rubber ball 13 of the float valve 10 are made of EPDM rubber, which is acid and alkali resistant and anti-aging. The inner diameter of the coarse cylinder 7 is larger than that of the discharge pipe 6 to ensure the movement space of the float valve 10. The overall buoyancy parameters of the float valve 10 can be optimized by adjusting the volume of the hollow jacket 14.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
