Description

Technical Field

[0001] The utility model relates to the technical field of feed production, in particular to a uniform feeding device for feed production. Background Art

[0002] Feed refers to food used to feed animals. It provides the nutrients and energy required by animals. Feed is made by crushing and mixing a variety of raw materials into granular food. The raw materials include grains, proteins, vitamins, etc. Reasonable feed ratio plays an important role in the growth and health of animals.

[0003] In feed production, most people use an auger to crush a mixture of various raw materials and feed it into a feed pellet machine to make the final granular product. When the auger is running, the friction between its own auger structure and the raw materials will usually produce a certain vibration force as a whole. Since the quality and volume of the various raw material particles and powders after crushing are different, the long-term vibration of the auger can easily cause the crushed mixture to form multiple layers of uneven distribution in the feeding barrel of the auger, which ultimately makes it difficult for the raw materials to be evenly transported into the auger, thus affecting the balance of the feed ratio;

[0004] At the same time, since feed raw materials usually contain some raw materials with high humidity and viscosity, such as corn, soybean meal, etc., after these raw materials are transported and discharged by the auger, due to the continuous friction between the auger structure and the raw materials, part of the raw materials may clump into agglomerates. After the agglomerated raw materials enter the feed pellet machine to form particles, they cannot be completely broken up, resulting in the possibility that some agglomerated parts may still remain in the feed pellets, which will cause uneven distribution of the raw materials in the feed pellets, affecting the quality and consistency of the feed pellets.

[0025] See also Figure 1-5As shown, a uniform feeding device for feed production includes a bottom plate 1, a storage barrel 2 is bolted to one side of the top of the bottom plate 1, an auger elevator 10 is installed on the other side of the top of the bottom plate 1, a feeding pipe 4 is connected to the bottom of the storage barrel 2, and the bottom end of the feeding pipe 4 is connected to the auger elevator 10, and a top cover 13 is installed on the top of the storage barrel 2. The top cover 13 is a two-stage hinged design. By opening one side of the hinged top cover 13, mixed raw material particles and powder can be put into the storage barrel 2. The inner cavity of the storage barrel 2 is provided with a flipping mechanism 5. The top cover 13 is used in conjunction with the flipping mechanism 5 to adjust the raw material particles and powder inside the storage barrel 2. The continuous turning process at the end can prevent the particles and powder materials in the storage barrel 2 from being unevenly distributed in layers due to the vibration generated by the auger elevator 10 during operation, so that the raw materials can be evenly distributed before entering the auger elevator 10. The uniform distribution of raw materials can make the formula ratio of the final finished feed accurate, avoiding the change of the quality of the finished feed due to uneven stratification of raw materials. The bottom of the inner cavity of the storage barrel 2 is provided with an anti-blocking mechanism 3. The anti-blocking mechanism 3 is used in conjunction with the turning mechanism 5 to improve the fluidity of the raw material particles and powder at the bottom of the storage barrel 2 and the feed pipe 4, which can effectively prevent the problem of raw material blockage. The problem is to ensure that the raw materials flow smoothly to the inside of the auger elevator 10. The top of the auger elevator 10 is connected to a discharge pipe 7, and the bottom of the discharge pipe 7 is connected to a processing shell 8. The bottom of the processing shell 8 is an open design to facilitate the discharge of the raw materials into the feed pellet machine for processing. The inner cavity of the processing shell 8 is provided with a dispersing mechanism 6, which can crush and disperse the raw materials, and can break up the raw materials after being transported by the auger elevator 10 to reduce the phenomenon of agglomeration, thereby avoiding the problem of agglomeration or uneven distribution in the finished feed, and can improve the quality and consistency of the feed product. The inner cavity of the processing shell 8 is located at the dispersing mechanism 6. A sieve plate 11 is arranged below the dispersing mechanism 6, and the surface of the sieve plate 11 is provided with evenly distributed sieve holes. Slide grooves 12 are arranged on both sides of the inner wall of the processing shell 8. The number of the slide grooves 12 is several and they are evenly distributed. Both ends of the sieve plate 11 extend through the slide grooves 12 to the outside of the processing shell 8. The sieve plate 11 is slidably connected to the inner wall of the slide groove 12.

[0026] The flipping mechanism 5 includes a driving motor 51, which is bolted to the top of the top cover 13 through a supporting frame. The output shaft of the driving motor 51 passes through the bottom of the top cover 13 and is rotatably connected to the penetration point through a bearing. A rotating shaft 52 is arranged at the center of the inner cavity of the storage barrel 2. The top end of the rotating shaft 52 is bolted to the output shaft of the driving motor 51. A spiral blade 53 is bolted to the surface of the rotating shaft 52. When the driving motor 51 provides power, the rotating shaft 52 and the spiral blade 53 can be driven to rotate, so that the rotating spiral blade 53 can contact and stir the raw material particles and powder in the storage barrel 2. Under the action of the shape of the spiral blade 53 itself, the raw material particles and powder can be continuously flipped up and down, so that a variety of raw material particles and powders can be fully mixed and evenly distributed, thereby preventing the vibration generated during the operation of the auger elevator 10 from causing the raw materials in the storage barrel 2 to be unevenly distributed in layers, thereby improving the accuracy of the proportion of the finished feed formula.

[0027] The anti-blocking mechanism 3 includes an upper scraper 31, one side of the upper scraper 31 is bolted to one side below the surface of the rotating shaft 52, the other side of the upper scraper 31 is slidably connected to the lower side of the inner wall of the storage barrel 2, the other side below the surface of the rotating shaft 52 is bolted to a lower scraper 32, one side of the lower scraper 32 is slidably connected to the inner wall of the feed pipe 4, the upper scraper 31 and the lower scraper 32 are symmetrically distributed about the central axis of the rotating shaft 52, when the rotating shaft 52 rotates, it can synchronously drive the upper scraper 31 and the lower scraper 32 to rotate to scrape the inner walls of the storage barrel 2 and the feed pipe 4, so as to prevent raw material particles and powder from being blocked. To prevent accumulation and blockage at the connection between the storage barrel 2 and the feed pipe 4, the top of the upper scraper 31 is fixedly connected to the upper lever 33, and the bottom of the lower scraper 32 is fixedly connected to the lower lever 34. The upper lever 33 and the lower lever 34 are both designed at an angle. When the upper scraper 31 and the lower scraper 32 rotate, they can respectively drive the upper lever 33 and the lower lever 34 to stir the raw material particles and powder, which can improve the fluidity of the raw material particles and powder at the bottom of the storage barrel 2 and the feed pipe 4, and ensure that the raw materials can flow smoothly to the inside of the auger elevator 10 for transportation.

[0028] The scattering mechanism 6 includes a first motor 61, which is bolted to one side of the processing shell 8 through a support frame, a first rotating rod 62 is provided on one side of the inner cavity of the processing shell 8, and a second rotating rod 66 is provided on the other side of the inner cavity of the processing shell 8. The first rotating rod 62 and both ends of the first rotating rod 62 penetrate the two sides of the processing shell 8 and are rotatably connected to the penetration point, one end of the first rotating rod 62 is fixedly connected to the output shaft of the first motor 61, the other end of the first rotating rod 62 is bolted to a first gear 63, one side of the first gear 63 is meshedly connected to a second gear 64, the second gear 64 is bolted to one end of the second rotating rod 66, and a crushing knife 65 is installed on the surface of the first rotating rod 62 and the second rotating rod 66. 5 is a plurality of pieces, and the crushing knives 65 on both sides are staggered. When the first motor 61 provides power to drive the first rotating rod 62 to rotate, the first rotating rod 62 and the second rotating rod 66 can respectively drive the crushing knives 65 on their surfaces to rotate synchronously in the inner cavity of the processing shell 8 through the meshing action of the second gear 64 and the first gear 63. The agglomerated raw materials falling from the discharge pipe 7 can be fully crushed and dispersed in the inner cavity of the processing shell 8 by the staggered rotating crushing knives 65, and the raw materials can be kept loose after being transported by the auger elevator 10, thereby preventing the problem of agglomerated raw materials in the final finished feed and improving the consistency of the feed product.

[0029] The shaking mechanism 9 includes a supporting plate 91, and the number of the supporting plates 91 is two. The supporting plates 91 on both sides are bolted to the lower part of the two sides of the processing shell 8 respectively. The top of the supporting plate 91 is fixedly connected with a compression spring 92. The number of the compression springs 92 is several and is equidistantly distributed. The top of the compression spring 92 is fixedly connected to the bottom of the sieve plate 11. A fixing rod 93 is bolted to one side of the first gear 63. A first cushion block 94 is fixedly connected to the top of the sieve plate 11 and located below the first gear 63. The first cushion block 94 corresponds to the position of the fixing rod 93. When the first gear 63 rotates, the fixing rod 93 can be driven to rotate synchronously, so that the rotating fixing rod 93 can knock on the top of the first cushion block 94. At this time, under the elastic action of the compression spring 92, a sufficient vibration effect can be provided to the sieve plate 11. A cam 95 is bolted to the other end of the second rotating rod 66. A second cushion block 96 is fixedly connected to the top of the sieve plate 11 and located below the cam 95. The cam 95 cooperates with the second cushion block 96 to form a cam 9 5 is the same as the angle of the fixed rod 93. When the dispersing mechanism 6 is in operation, the fixed rod 93 and the cam 95 can be driven to rotate synchronously in opposite directions, so that they can knock the first cushion block 94 and the second cushion block 96 respectively, so that the two sides of the screen plate 11 can be synchronously lowered in the slide groove 12. Under the cooperation of a plurality of compression springs 92, a sufficient shaking effect can be provided to the two sides of the screen plate 11, which can ensure that the raw materials dispersed by the dispersing mechanism 6 are evenly distributed on the screen plate 11 and pass smoothly, and can also prevent the larger agglomerated raw materials that are not dispersed by the dispersing mechanism 6 from falling, thereby improving the quality of the final feed product. Baffles 14 are fixedly connected to both sides of the top of the screen plate 11, and one side of the baffle 14 is slidably connected to the surface of the processing shell 8. When the screen plate 11 moves downward from the slide groove 12, the baffle 14 can block the slide groove 12, which can prevent the raw materials on the top of the sieve hole of the screen plate 11 from sliding down from the slide groove 12, thereby improving the effect of the screen plate 11 on the screening of the raw materials.

[0030] It is worth noting that the auger hoist 10 proposed in this technical solution is a prior art, and its working principle and beneficial effects when used are not described in detail here.

[0031] Working principle: first open the top cover 13 and put the raw material particles and powder mixed in proportion into the storage barrel 2, then start the auger elevator 10 to transport the raw materials in the storage barrel 2 through the feeding pipe 4, then start the driving motor 51 to drive the rotating shaft 52 to rotate, so that the spiral blade 53 can use its own shape to continuously roll the raw material particles and powder up and down in the storage barrel 2, so that a variety of raw material particles and powders can be fully mixed and evenly distributed, thereby avoiding the uneven distribution of raw materials in the storage barrel 2. At the same time, the rotating shaft 52 can drive the upper scraper 31 and the lower scraper 32 to scrape the inner wall of the connection between the storage barrel 2 and the feeding pipe 4, and the upper lever 33 and the lower lever 34 can stir the raw materials, which can improve the fluidity of the raw material particles and powder to avoid blockage. When the tube 7 is discharged, the first motor 61 is started first to drive the first rotating rod 62 to rotate. Through the meshing rotation of the second gear 64 and the first gear 63, the first rotating rod 62 and the second rotating rod 66 can respectively drive the crushing knives 65 staggered on their surfaces to rotate toward each other, so that the raw materials falling from the discharge pipe 7 can be crushed, so that the raw materials can be kept in a loose state, and the rotation of the first gear 63 and the second rotating rod 66 can respectively drive the fixed rod 93 and the cam 95 to rotate, so that they can knock the first cushion block 94 and the second cushion block 96 respectively, so that the two sides of the screen plate 11 can be synchronously lowered in the slide 12, and under the elastic action of the compression spring 92, the screen plate 11 can be provided with a sufficient shaking effect, which can ensure that the raw materials scattered by the scattering mechanism 6 fall smoothly in the sieve holes of the screen plate 11 for subsequent processing, thereby improving the quality and consistency of the final feed product.
