Description

Technical Field

[0001] This invention relates to the field of force-feeding technology for mules and ducks, and more particularly to a feed addition device for force-feeding mules and ducks. Background Technology

[0002] Muscovy ducks are a type of artificially bred hybrid duck, produced by crossing male Muscovy ducks (of the genus Muscovy) with female ducks (of the genus Amur duck, usually Peking duck, Cherry Valley duck, etc.). They combine the excellent characteristics of their parents and are characterized by fast growth, large size, tender meat, and high feed conversion rate. They are an important breed for meat production in livestock and poultry farming. Through scientific feeding during the force-feeding period, they can quickly accumulate fat and improve the flavor of the meat, thus occupying an important position in the breeding industry.

[0003] Currently, most feed additive devices used in the industry for force-feeding mule and ducks employ a single-shaft mixing method during feed mixing. The movement trajectory of the main feed and auxiliary materials within the mixing tank is fixed, which easily leads to stratification due to density differences, resulting in insufficient mixing uniformity. At the same time, feed tends to adhere to the inner wall of the mixing tank during the mixing process. Traditional devices lack targeted cleaning structures, which not only wastes feed but also affects the quality of subsequent batches of feed due to residual feed spoilage, increasing equipment maintenance costs. Secondly, in the auxiliary material addition stage, most devices rely on manual control of the amount of auxiliary material added, lacking a quantitative control mechanism. This makes it impossible to accurately match the ratio of auxiliary materials according to the growth stage of mule and ducks. Some devices equipped with adding hoppers often experience problems with the feeding channel being blocked because the auxiliary materials are prone to absorbing moisture and clumping. Furthermore, the adding hoppers lack an active cleaning structure, requiring frequent manual unblocking, which seriously affects the continuity of force-feeding.

[0004] When discharging the mixed feed, existing devices mostly use gravity flow or simple push structures. However, due to the high viscosity of the mixed feed, it is easy for it to accumulate in the discharge pipe, causing discharge interruption, unstable transmission, and inability to achieve uniform discharge. This results in inconsistent feeding amounts, affecting the digestion and absorption of mules and ducks. Furthermore, since mules and ducks instinctively struggle during force-feeding, traditional rigid clamping structures cannot buffer the impact force, which can easily lead to limb injuries and misalignment of the feeding pipe due to unstable clamping, increasing the difficulty of operation and the risk of force-feeding. Therefore, we propose a feed addition device for mules and ducks during force-feeding. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This feed addition device for mule ducks during force-feeding can drive a dual-shaft motor to rotate a first rotating shaft, thereby enabling multiple stirring rods to perform multi-dimensional mixing of the main feed and auxiliary materials. Combined with an L-shaped scraper to clean the inner wall of the mixing box in real time, it greatly improves the uniformity of mixing. At the same time, the first rotating shaft drives the auxiliary material scraper in the auxiliary material addition hopper to rotate through gear transmission, which can prevent the auxiliary material from clumping and clogging. Combined with a quantitative control valve, it can achieve precise addition and meet the nutritional needs of mule ducks at different growth stages.

[0018] 2. This feed addition device for mule and duck force-feeding uses a dual-shaft motor to drive the main cone wheel to rotate. With the meshing transmission of the driven cone wheel, the second rotating shaft drives the spiral discharge blades to rotate at a constant speed in the discharge pipe. This replaces the traditional gravity flow or simple pushing method, effectively preventing high-viscosity feed from accumulating and clogging in the pipe, ensuring a uniform and stable discharge volume, ensuring precise control of the force-feeding amount for mule and duck, and improving the digestion and absorption efficiency of mule and duck.

[0019] 3. This feeding device for mule ducks during force-feeding uses a drive motor to rotate a bidirectional lead screw, which causes the first clamping block and the second clamping block to move closer together. In conjunction with the first and second buffer blocks, the telescopic column, and the buffer spring, a buffer assembly can achieve stable clamping while elastically buffering the impact force generated by the mule ducks' struggles, thus preventing limb injuries. At the same time, the telescopic tube and the non-slip handle facilitate the adjustment of the feeding tube position, ensuring accurate alignment and reducing the difficulty of operation and the risk of force-feeding.

[0033] In one embodiment of the present invention, the mixing assembly includes a dual-shaft motor 9, which is fixedly installed at the lower end of the mixing tank 2. A first rotating shaft 11 is fixedly connected to the upper output end of the dual-shaft motor 9, and the first rotating shaft 11 is rotatably connected to the mixing tank 2. Multiple stirring rods 12 are fixedly connected to the outer side of the first rotating shaft 11, and all stirring rods 12 are located within the inner cavity of the mixing tank 2. Two L-shaped scrapers 13 are also fixedly connected to the outer side of the first rotating shaft 11, and the outer sides of both L-shaped scrapers 13 are slidably connected to the inner wall of the mixing tank 2. In use, the main feed is fed through the main addition pipe. 8. Inject into the mixing tank 2. At the same time, the required different auxiliary materials are transported to the first auxiliary material addition hopper 3 and the second auxiliary material addition hopper 4 respectively through the auxiliary material addition pipe 7. The addition amount of auxiliary materials is precisely controlled by the first quantitative control valve 5 and the second quantitative control valve 6. At this time, the dual-shaft motor 9 is started.

At the same time, the L-shaped scraper 13 rotates synchronously with the first rotating shaft 11 to scrape off the feed attached to the inner wall of the mixing tank 2, so as to avoid waste caused by feed sticking to the wall.

[0034] As one aspect of the present invention, scraping assemblies are provided on the inner sides of the first auxiliary material adding hopper 3 and the second auxiliary material adding hopper 4. The scraping assembly includes a driven gear 15, and two driven gears 15 are rotatably connected between the corresponding first auxiliary material adding hopper 3 and the first quantitative control valve 5, and between the second auxiliary material adding hopper 4 and the second quantitative control valve 6, respectively.

[0035] In one embodiment of the present invention, the discharge assembly includes a second rotating shaft 22, which is rotatably connected to a discharge pipe 20. A rotating bracket 21 is rotatably connected to the front end of the second rotating shaft 22. The outer side of the rotating bracket 21 is fixedly connected to the discharge pipe 20. A spiral discharge blade 23 is fixedly connected to the outer side of the second rotating shaft 22. The spiral discharge blade 23 is disposed on the inner side of the discharge pipe 20. A fixing plate 17 is fixedly connected to the outer side of the discharge pipe 20. Both ends of the fixing plate 17 are fixedly connected to a support frame 1. The lower output end of the dual-shaft motor 9 is fixedly connected to the main cone wheel 24, and the outer side of the main cone wheel 24 is engaged with the driven cone wheel 25. The front end of the driven cone wheel 25 is fixedly connected to the second rotating shaft 22. At this time, the mixed feed, after being regulated by the third quantitative control valve 19, can be discharged into the discharge pipe 20 through the discharge pipe 18. At this time, the lower output end of the dual-shaft motor 9 drives the driven cone wheel 25 to rotate through the main cone wheel 24, causing the second rotating shaft 22 and the spiral discharge blade 23 to rotate, which can push the feed in the discharge pipe 20 to the telescopic pipe 26.

[0036] As one embodiment of the present invention, the clamping assembly includes a drive motor 31, which is fixedly mounted on one side of the fixed base 29. The output end of the drive motor 31 is fixedly connected to a bidirectional lead screw 32. The inner side of the placement groove 30 is provided with a sliding groove 35 that is opened on the fixed base 29. The bidirectional lead screw 32 is rotatably connected to the inner side of the sliding groove 35. The inner side of the sliding groove 35 is slidably connected to a first clamping block 33 and a second clamping block 34. The first clamping block 33 and the sliding groove 35 are threadedly connected to the forward and reverse threaded sections of the bidirectional lead screw 32. By starting the drive motor 31, the bidirectional lead screw 32 is driven to rotate. At this time, under the guidance of the sliding groove 35, the first clamping block 33 and the second clamping block 34 can be brought closer to each other, stably clamping the mule duck placed in the placement groove 30 of the fixed base 29.

[0037] In one embodiment of the present invention, a receiving groove 38 is provided at the adjacent ends of the first clamping block 33 and the second clamping block 34. A first buffer block 36 is slidably connected to the inner side of the receiving groove 38 on the first clamping block 33, and a second buffer block 37 is slidably connected to the inner side of the receiving groove 38 on the second clamping block 34.

When the mule and duck are clamped by the first clamping block 33 and the second clamping block 34, the first buffer block 36 on the inner side of the first clamping block 33 and the second buffer block 37 on the inner side of the second clamping block 34 will first contact the mule and duck. At this time, with the help of the elastic cooperation between the telescopic column 39 and the buffer spring 40, the mule and duck can be firmly clamped and fixed, and the force generated when the mule and duck struggles and bumps due to non-cooperation can be effectively buffered, so as to avoid damage to the mule and duck during the clamping process.

[0038] As one aspect of the present invention, a handle 27 is fixedly connected at the connection between the telescopic tube 26 and the feeding tube 28. The outer side of the handle 27 is provided with anti-slip texture. By holding the handle 27 with anti-slip texture, the position of the feeding tube 28 can be adjusted so that it is aligned with the esophagus of the clamped mule duck, and finally the feeding operation of the mule duck is completed through the feeding tube 28.

[0039] It should be noted that during use, the operator first injects the main feed into the mixing tank 2 through the main addition pipe 8. Simultaneously, the required auxiliary materials are conveyed to the first auxiliary material addition hopper 3 and the second auxiliary material addition hopper 4 through the auxiliary material addition pipe 7. The addition amount of auxiliary materials is precisely controlled by the first quantitative control valve 5 and the second quantitative control valve 6. At this time, the dual-shaft motor 9 is started. The upper output end of the dual-shaft motor 9 drives the first rotating shaft 11 to rotate, causing the stirring rod 12 to fully mix the main feed and auxiliary materials in the mixing tank 2. Simultaneously, the L-shaped scraper 13 rotates synchronously with the first rotating shaft 11, scraping off the feed adhering to the inner wall of the mixing tank 2 to avoid waste due to feed sticking to the wall. The rotation of the first rotating shaft 11 also drives the upper drive gear 14 to rotate, which in turn drives the two driven gears 15 to rotate, causing the auxiliary material scrapers 16 in the first and second auxiliary material addition hoppers 3 and 4 to rotate accordingly, preventing the auxiliary materials from clumping in the addition hoppers. When a blockage occurs, the drive motor 31 is activated to rotate the bidirectional lead screw 32. Guided by the sliding groove 35, the first clamping block 33 and the second clamping block 34 move closer to each other. Then, with the help of the first buffer block 36 and the second buffer block 37, and the buffer assembly composed of the telescopic column 39 and the buffer spring 40, the mule and duck placed in the placement groove 30 of the fixed seat 29 are stably clamped. Finally, the mixed feed is regulated by the third quantitative control valve 19 and discharged into the discharge pipe 20 through the discharge pipe 18. At this time, the lower output end of the dual-shaft motor 9 drives the secondary cone wheel 25 to rotate through the main cone wheel 24, causing the second rotating shaft 22 and the spiral discharge blade 23 to rotate, pushing the feed to the telescopic pipe 26. The operator holds the handle 27 with anti-slip texture and adjusts the position of the feeding pipe 28 through the telescopic pipe 26 to align it with the clamped mule and duck. Finally, the feeding operation of the mule and duck is completed through the feeding pipe 28.
