[0043] Please refer to Figures 1 - 7 As shown, the present invention is an agricultural livestock feed processing pretreatment device, including a working box 1, a discharge port 4, a crushing box 2 and a feeding pipe 3; it also includes a crushing and filtering unit arranged in the crushing box 2;

[0044] The discharge port 4 is fixedly arranged at the bottom of the working box 1;

[0045] The crushing box 2 is fixedly arranged on the top of the working box 1;

[0046] The feeding pipe 3 is fixedly arranged at one end of the crushing box 2;

[0047] The crushing and filtering unit includes a driving assembly, a crushing assembly 31 and a filtering assembly 32; the driving assembly drives the crushing assembly 31 to rotate; the driving assembly drives the filtering assembly 32 to vibrate;

[0048] The grass and grains for making agricultural livestock feed are fed into the crushing assembly 31 in the crushing box 2 through the feed pipe 3. Then, the drive assembly is started to drive the crushing assembly 31 to rotate. The rotating crushing assembly 31 crushes the fed grass and grains. The crushed materials will fall onto the filtering assembly 32 in the working box 1. The drive assembly will drive the filtering assembly 32 to vibrate, so that the filtering assembly 32 screens the crushed materials, removing the large particulate matters in the materials. The materials passing through the filtering assembly 32 will be discharged through the discharge port 4 at the bottom of the working box 1;

[0049] The staff first pour materials such as grass and grains into the feed pipe 3, and the feed pipe 3 feeds the materials such as grass and grains into the crushing assembly 31 in the crushing box 2. Then, the crushing assembly 31 grinds and crushes the materials such as grass and grains. By the rotation of the crushing assembly 31, the materials such as grass and grains are rotated, ground and crushed in the crushing assembly 31. This setting is to enable the materials such as grass and grains to be evenly arranged in the crushing assembly 31 and to be ground and passed through. When adding materials such as grass and grains later, they will not be mixed with the ground and crushed materials, but will be placed together with the unground materials waiting to be ground;

[0050] When the materials such as grass and grains are ground and crushed, they will fall onto the filtering assembly 32 in the working box 1. Then, the drive assembly drives the filtering assembly 32 to vibrate, so that the filtering assembly 32 filters and screens the ground and crushed grass and grains. This setting is to remove the large particulate matters in the grass and grains, making the materials passing through the filtering assembly 32 have the same particle size. Then, they are discharged through the discharge port 4 for unified further processing, ensuring that the particle size of the materials is the same and avoiding uneven particle thickness of the materials, which may affect the quality of the final product.

[0051] Please refer to Figures 1 to 5 As shown, the drive assembly includes a first gear 12, a first connecting shaft 14, a second gear 13 and a second connecting shaft 19;

[0052] The crushing assembly 31 includes a crushing chamber 15, crushing blocks 20, fixing rods 21 and crushing rods 16

[0053] Among them, the second connecting shaft 19 is rotatably arranged on the crushing box 2, and the second connecting shaft 19 penetrates through the crushing box 2; the second gear 13 is fixedly arranged at one end of the second connecting shaft 19 outside the crushing box 2; the crushing chamber 15 is fixedly arranged at one end of the second connecting shaft 19 inside the crushing box 2; the first connecting shaft 14 is rotatably arranged inside the second connecting shaft 19; the first gear 12 is fixedly arranged at one end of the first connecting shaft 14 outside the crushing box 2; the crushing block 20 is fixedly arranged at one end of the first connecting shaft 14 inside the crushing box 2; the fixing rod 21 is fixedly arranged on the crushing block 20; the crushing rod 16 is fixedly arranged at one end of the fixing rod 21, and the crushing rod 16 slides on the inner wall of the crushing chamber 15; one end of the feed pipe 3 extends into the crushing chamber 15;

[0054] The second gear 13 rotates to drive the second connecting shaft 19 to rotate. The rotating second connecting shaft 19 drives the crushing chamber 15 to rotate. The feed pipe 3 is fixed on the crushing box 2, but one end of the feed pipe 3 extends into the crushing chamber 15 to send materials such as forage and grains into the interior of the crushing chamber 15. Then the first gear 12 rotates. The rotating first gear 12 drives the first connecting shaft 14 to rotate. The rotating first connecting shaft 14 drives the crushing block 20 to rotate. The rotating crushing block 20 drives the fixing rod 21 and the crushing rod 16 to rotate. The crushing rod 16 and the crushing chamber 15 rotate in opposite directions. Therefore, after the crushing rod 16 and the crushing chamber 15 cooperate to crush materials such as forage and grains by extrusion, the rotation of the crushing chamber 15 can turn the internal materials to prevent the materials from piling up together and affecting the crushing of the materials by the crushing rod 16.

[0055] Please refer to Figures 1 to 3 As shown, the driving assembly further includes a support plate 5, a driving motor 6, a rotating rod 7, a fixing plate 10 and a bevel gear 11;

[0056] Among them, the support plate 5 is fixedly arranged on one side of the working box 1; the rotating rod 7 is rotatably arranged on the top of the support plate 5; the driving motor 6 is fixedly arranged at the bottom of the support plate 5, and the driving motor 6 is communicated with the rotating rod 7; the fixing plate 10 is fixedly arranged on the crushing box 2; the rotating rod 7 penetrates through the fixing plate 10; the bevel gear 11 is fixedly arranged on the top of the rotating rod 7; the bevel gear 11 meshes with the first gear 12 and the second gear 13;

[0057] The rotating rod 7 on the support plate 5 is driven to rotate by the driving motor 6. The rotation of the rotating rod 7 causes the bevel gear 11 at the top to rotate. The rotating bevel gear 11 meshes with the first gear 12 and the second gear 13. Therefore, when the bevel gear 11 rotates, the first gear 12 and the second gear 13 will rotate, causing the first gear 12 and the second gear 13 to rotate in different directions, so that the first connecting shaft 14 and the second connecting shaft 19 turn in different directions. The fixed plate 10 and the support plate 5 play a role in supporting and fixing.

[0058] Please refer to Figure 1 、 Figure 2 and Figure 6 As shown in, the driving assembly further includes a worm gear 8 and a worm 9;

[0059] The filtering assembly 32 includes a filter plate 18, a moving column 26, a spring 28, a sliding block 27 and a knocking block 25

[0060] Among them, the worm gear 8 is fixedly arranged on the rotating rod 7; the worm 9 is rotatably arranged in the working box 1, and one end of the worm 9 penetrates through the working box 1; the worm 9 meshes with the worm gear 8;

[0061] The sliding block 27 is fixedly arranged in the working box 1; there are four sliding blocks 27, and two of them are symmetrically arranged in the working box 1 in a group; the moving column 26 is slidably arranged on the sliding block 27; the filter plate 18 is fixedly arranged on the top of the moving column 26; the spring 28 is sleeved on the moving column 26, and both ends of the spring 28 are fixedly connected to the moving column 26 and the sliding block 27 respectively; the knocking block 25 is fixedly arranged in the middle of the worm 9.

[0062] The rotation of the rotating rod 7 drives the worm gear 8 to rotate. The worm 9 meshes with the worm gear 8. Therefore, when the worm gear 8 rotates, it will drive the worm 9 to rotate, so that the knocking block 25 on the worm 9 rotates. The rotating knocking block 25 will lift the filter plate 18, causing the moving column 26 on the filter plate 18 to slide on the sliding block 27. The sliding of the sliding block 27 will squeeze the spring 28 to make the spring 28 contract. When the knocking block 25 is not in contact with the filter plate 18, the spring 28 will pull the moving column 26 to move downward and make the filter plate 18 quickly hit the sliding block 27, causing the filter plate 18 to vibrate, thereby vibrating and filtering the materials on the filter plate 18 to allow qualified materials to pass through the filter plate 18.

[0063] Please refer to Figure 2 and Figure 4As shown, a limiting groove 17 is fixedly connected to the crushing bin 15; there are two limiting grooves 17, and they are symmetrically arranged on the crushing bin 15; a fixing block 22 is fixedly connected to the inner wall of the crushing box 2; there are eight fixing blocks 22, and they are symmetrically arranged on the inner wall of the crushing box 2; a roller 23 is rotatably connected to the fixing block 22; the roller 23 slides in the limiting groove 17;

[0064] When the second connecting shaft 19 drives the crushing bin 15 to rotate, to prevent the crushing bin 15 from shifting in the crushing box 2, fixing blocks 22 and rollers 23 are arranged in the crushing box 2, so that the rollers 23 on the fixing blocks 22 slide in the limiting grooves 17 of the crushing bin 15. In this way, the rollers 23 will be stuck in the limiting grooves 17 of the crushing bin 15. When the second connecting column drives the crushing bin 15 to rotate, with the cooperation of the rollers 23 and the limiting grooves 17, the crushing bin 15 can rotate smoothly in the crushing box 2 and will not slip or deviate.

[0065] Please refer to Figure 4 As shown, a cleaning plate 29 is fixedly connected to the inner part of the upper part of the crushing box 2; there are two cleaning plates 29, and they are symmetrically arranged inside the crushing box 2; brush heads 30 are fixedly connected to the cleaning plate 29 at equal intervals and evenly; the brush heads 30 slide on the surface of the crushing bin 15;

[0066] When the crushing bin 15 and the crushing rod 16 cooperate to roll and crush materials such as forage and grains, to prevent the materials after rolling and crushing from blocking the holes on the crushing bin 15, the cleaning plate 29 and the brush heads 30 are fixed on the inner wall of the crushing box 2. When the crushing bin 15 rotates, the fixed cleaning plate 29 and brush heads 30 will brush the holes on the crushing bin 15 to clean the material blockages stuck on the crushing bin 15.

[0067] Please refer to Figure 2 and Figure 5 As shown, a plurality of fixing rods 21 are arranged, and they are arranged on the crushing block 20 at equal intervals and evenly;

[0068] By arranging a plurality of fixing rods 21 and the corresponding crushing rods 16, the materials such as forage and grains in the crushing bin 15 can be rolled and crushed better, achieving a higher crushing efficiency.

[0069] Please refer to Figures 1 to 7 As shown, an agricultural livestock feed processing pretreatment method, this processing pretreatment method includes the following steps:

[0070] S1: First, put materials such as forage and grains into the feed pipe 3 on the crushing box 2, and the feed pipe 3 sends the materials into the crushing bin 15;

[0071] S2: The second connecting shaft 19 drives the crushing chamber 15 to rotate, and then the first connecting shaft 14 drives the crushing rod 16 to rotate. The crushing chamber 15 and the crushing rod 16 cooperate with each other to roll and crush the materials placed in the crushing chamber 15.

[0072] S3: The materials after rolling and crushing will fall onto the filter plate 18 through the crushing chamber 15. The filter plate 18 screens the materials after rolling and crushing, blocks the large particulate matters in the materials, and allows the qualified material particles to fall into the bottom discharge port 4 of the working box 1. The materials are discharged from the discharge port 4.

[0073] The working principle of the present invention: The staff first pour materials such as forage and grains into the feeding pipe 3. The feeding pipe 3 sends the materials such as forage and grains into the crushing component 31 in the crushing box 2. Then the crushing component 31 grinds and crushes the materials such as forage and grains. By the rotation of the crushing component 31, the materials such as forage and grains are rotated and ground and crushed in the crushing component 31. This setting is to enable the materials such as forage and grains to be evenly arranged in the crushing component 31 and to allow the materials to be ground and passed through. When adding materials such as forage and grains later, they will not be mixed with the ground and crushed materials, but will be placed together with the unground materials waiting to be ground.

[0074] When the materials such as forage and grains are ground and crushed, they will fall onto the filtering component 32 in the working box 1. Then the driving component drives the filtering component 32 to vibrate, so that the filtering component 32 filters and screens the ground and crushed forage and grains. This setting is to remove the large particulate matters in the forage and grains and make the materials passing through the filtering component 32 have the same particle size. Then they are discharged from the discharge port 4 for unified next-step processing, ensuring that the particle size of the materials is the same and avoiding uneven particle thickness of the materials, which affects the quality of the final product.

[0075] The above has described a detailed description of an embodiment of the present invention. However, the content described above is only a preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention.
