[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0028] Example 1

[0029] like Figures 1 to 8 As shown, a livestock feed grinding device includes a grinder 1;

[0030] A feeding frame 2 is installed at the feeding port of the crusher 1. Multiple rollers 5 are installed inside the feeding frame 2. The rollers 5 are horizontal and rotatably installed at equal intervals at the bottom of the feeding frame 2. A U-shaped frame 4 is installed on the surface of the feeding frame 2. A feeding plate 16 is installed inside the U-shaped frame 4. L-shaped slides 14 are fixedly installed at both ends of the feeding plate 16. A sliding column 15 is fixedly installed on one side surface of the L-shaped slide 14. A rectangular groove 13 adapted to the sliding column 15 is opened on the inner wall of the U-shaped frame 4. The feeding plate 16 is slidably connected in the U-shaped frame 4 through the sliding column 15 and the rectangular groove 13.

[0031] Multiple horizontally spaced and equally spaced rollers 5 rotate to provide stable and uniform conveying power for feed such as straw, preventing the feed from getting stuck, piling up or shifting during the feeding process, and ensuring the smooth conveying process to the feed inlet of the crusher 1. The feed plate 16 is slidably connected to the U-shaped frame 4 through the sliding column 15 and the rectangular groove 13, so that the feed plate 16 can move flexibly within the U-shaped frame 4. The position of the feed plate 16 can be easily adjusted according to actual production needs, and the feed conveying can be precisely controlled to achieve on-demand feeding.

[0032] Furthermore, a rectangular sleeve 10 is slidably connected to the surface of the L-shaped carriage 14, and an internal gear ring 9 is slidably connected inside the rectangular sleeve 10. One end of the L-shaped carriage 14 is connected to the internal gear ring 9, and a gear 8 meshes with the surface of the internal gear ring 9. A transmission rod 7 is mounted on the surface of the gear 8, and one end of the transmission rod 7 passes through the U-shaped frame 4. A servo motor 6 is mounted on the surface of the U-shaped frame 4, and the transmission rod 7 is connected to the output shaft end of the servo motor 6.

[0033] The gear 8 meshes with the internal gear ring 9, providing accurate transmission ratio. This allows the servo motor 6 to transmit power to the internal gear ring 9 stably and precisely, thereby driving the L-shaped carriage 14 and related components. This ensures that the feeding action follows a preset rhythm and pattern, achieving stable and reliable automatic feeding with high precision. It eliminates the need for extensive manual labor, reducing manpower requirements and labor costs. It also avoids the possibility of untimely or uneven material supply that may occur during manual feeding, helping to ensure consistent product quality. Furthermore, the automatic feeding design isolates workers from hazardous areas, reducing the probability of accidents.

[0034] Furthermore, a guide block 11 is fixedly installed on one side surface of the rectangular sleeve 10, and a guide groove 12 adapted to the guide block 11 is opened on the inner wall of the U-shaped frame 4. The rectangular sleeve 10 is slidably connected to the inner wall of the U-shaped frame 4 through the guide block 11 and the guide groove 12.

[0035] The cooperation between the guide block 11 and the guide groove 12 restricts the movement trajectory of the rectangular sleeve 10, allowing it to slide only along the direction of the guide groove 12. This prevents the rectangular sleeve 10 from shaking or shifting during movement, ensuring the accuracy of the entire mechanism's movement. As a result, components such as the feeding plate 16 can move accurately along a predetermined path, ensuring the stable operation of feeding and other actions of the feed crushing device.

[0036] Furthermore, a feeding plate 19 is provided at the bottom of the feeding plate 16, and a T-shaped rod 17 is slidably connected to the surface of the feeding plate 16. One end of the T-shaped rod 17 is connected to the feeding plate 19, and a spring 18 is sleeved on the surface of the T-shaped rod 17 between the feeding plate 16 and the feeding plate 19. The contact surface between the feeding plate 19 and the straw is provided with a concave-convex structure.

[0037] The concave-convex structure of the feeding plate 19 in contact with the straw significantly increases the friction between the feeding plate 19 and the straw. When the feeding plate 19 moves under the action of the device, the concave-convex structure can firmly grasp the straw, preventing the straw from slipping or shifting during the feeding process, ensuring that the straw is stably and accurately conveyed to the feeding port of the crusher 1, and improving the stability and reliability of the feeding.

[0038] Example 2

[0039] Improvements based on Example 1:

[0040] Furthermore, multiple feeding cone teeth 20 are installed at equal intervals on the bottom surface of the feeding plate 16. The bottom ends of the multiple feeding cone teeth 20 are all cone-shaped. Through holes that are adapted to the feeding cone teeth 20 are opened at the relative positions on the surface of the feeding plate 19.

[0041] The bottom of the feeding cone 20 is cone-shaped, which can easily insert into materials such as straw, increasing the contact area and friction with the material, thereby better gripping the material. Under the relative movement of the feeding plate 16 and the feeding plate 19, the material inserted by the cone 20 will be smoothly conveyed forward. This structure is very effective for conveying some soft and easily scattered materials, which can improve the material conveying efficiency and reduce material loss. During the feeding process, when the feeding cone 20 is pulled out of the through hole of the feeding plate 19, some material wrapped around the cone 20 may be brought out, which plays a certain self-cleaning role, reducing the residue and accumulation of material inside the equipment, reducing the probability of equipment failure due to material blockage, and also helping to keep the inside of the equipment clean and extend the service life of the equipment.

[0042] Furthermore, a limit frame 22 is installed on the surface of the feeding rack 2, and a rotating rod 23 is rotatably connected to the surface of the limit frame 22. Multiple sets of hinge frames 24 are installed on the surface of the rotating rod 23, and a striking rod 25 is rotatably connected in each set of hinge frames 24. The end of the striking rod 25 is arranged in a fan-shaped structure.

[0043] The striking rod 25 has a fan-shaped end. When the rotating rod 23 rotates, the striking rod 25 can strike the material in the feeding rack 2. For materials that may accumulate or stick together, the fan-shaped striking rod 25 can break them up with a large contact area and striking force, preventing the material from blocking the feeding rack 2 and ensuring the smooth flow of the feeding channel. This allows the material to be smoothly transported to the subsequent processing stage. At the same time, the striking rod 25 knocks off the dust on the surface of the straw during the feeding stage, greatly reducing the amount of dust generated in the subsequent crushing stage and lowering the dust concentration in the air of the workplace, creating a healthier and cleaner working environment for the operators.

[0044] Furthermore, the rotating rod 23 and the transmission rod 7 are connected by a belt drive assembly 21.

[0045] When the equipment is overloaded, such as when straw or other feed blocks the drive rod 23 or transmission rod 7, causing excessive load, slippage will occur between the belt and pulley, thus cutting off power transmission. This slippage prevents the equipment from being damaged due to overload, providing a certain degree of protection. Once the blockage is cleared, the equipment can resume normal operation without the need for complex repairs.

[0046] Furthermore, a collection hopper 3 is installed at the bottom of the feeding rack 2, and the collection hopper 3 is funnel-shaped.

[0047] The funnel-shaped structure has a large opening and a small bottom, which can catch materials falling from the feeding rack 2, as well as dust and impurities knocked down by the striking rod 25. This allows these materials to smoothly converge to the bottom and prevents them from scattering outside the collection hopper 3, thus improving the efficiency and integrity of material collection.

[0048] It should be noted that a vacuum cleaner is installed at the outlet of collection hopper 3 to absorb dust. The vacuum cleaner can generate strong suction to absorb all the dust and any remaining tiny particles in collection hopper 3, reducing dust residue in collection hopper 3 and improving the thoroughness of dust collection.

[0049] Working principle: Place the straw on the feeding frame 2, start the servo motor 6, the servo motor 6 drives the transmission rod 7 to rotate, the gear 8 on the transmission rod 7 rotates accordingly, and through meshing with the internal gear ring 9, drives the L-shaped slide 14 to slide along the rectangular sleeve 10, thereby causing the feeding plate 16 to move within the U-shaped frame 4.

[0050] During the movement of the feeding plate 16, the feeding cone teeth 20 pass through the through holes on the feeding plate 19, pushing the feeding plate 19 downward and compressing the spring 18. When the feeding cone teeth 20 leave the through holes, the spring 18 rebounds, and the feeding plate 19 moves upward. Since the contact surface between the feeding plate 19 and the straw has a concave-convex structure, it can effectively contact the straw and increase the feeding force. In conjunction with the back-and-forth movement of the feeding plate 16, the straw is gradually pushed towards the roller shaft 5, and driven by the roller shaft 5, the straw is conveyed to the feeding port of the crusher 1. At the same time, the transmission rod 7 drives the rotating rod 23 to rotate through the belt transmission group 21. The striking rod 25 on the rotating rod 23 swings accordingly, striking the surface of the straw to remove dust and impurities from the surface of the straw. The dust and impurities fall into the collection hopper 3.

[0051] Straw is conveyed by the feeding rack 2 and enters the crusher 1 for crushing. The crushed feed can be collected and utilized later.

[0052] It should be noted that when gear 8 meshes and rotates in the straight section of the internal gear ring 9, the internal gear ring 9 can push the rectangular sleeve 10, and the rectangular sleeve 10 slides in the guide groove 12 under the action of the guide block 11. At the same time, the sliding column 15 on the surface of the L-shaped slide 14 can slide parallel in the rectangular groove 13. When gear 8 meshes and drives the arc-shaped section of the internal gear ring 9, the internal gear ring 9 no longer pushes the rectangular sleeve 10. At this time, the internal gear ring 9 slides up and down in the rectangular sleeve 10. At the same time, the internal gear ring 9 can drive the L-shaped slide 14 and simultaneously move the feeding plate 16 towards the side closer to the straw. At this time, with the cooperation of the feeding plate 19 and the feeding bevel tooth 20, after the material is clamped, gear 8 can mesh and rotate again in the straight section of the internal gear ring 9. At this time, the clamped straw is horizontally transferred so that the straw feed can be automatically fed into the feeding port of the crusher 1, thereby realizing automated feeding, reducing manual intervention, and improving crushing efficiency.
