[0031] The supporting assembly includes two supporting rails 5 movably abutted against the lower end surface of the inclined mesh disk 4, and the two supporting rails 5 have different heights. The lower end of the inclined mesh disk 4 is located inside the supporting rail 5 and is fixedly installed with two symmetrically distributed connecting blocks 6. The lower end of the connecting block 6 is located inside the supporting rail 5 and is fixedly connected with a slider 7. The cross-sectional shape of the slider 7 is circular. A movable groove 8 is opened inside the supporting rail 5 corresponding to the connecting block 6 and the slider 7, and the connecting block 6 and the slider 7 are in sliding contact with the supporting rail 5 through the movable groove 8. The front end of the slider 7 is movably abutted with a spring 9.

[0032] One end of the spring 9 away from the slider 7 is movably abutted against the support rail 5, and a discharge groove 10 is provided at the lower end of the support rail 5 corresponding to the movable groove 18. The discharge groove 10 can prevent the spring 9 from being stuck by the crushed feed, and the discharge groove 10 is connected to the movable groove 18. The lower end of the inclined mesh plate 4 is located between the two connecting blocks 6 and a stopper 11 is fixedly installed thereon. A movable groove 2 12 is provided on the support rail 5 corresponding to the stopper 11, and the stopper 11 is in sliding contact with the support rail 5 through the movable groove 2 12. The driving mechanism includes a rotating shaft 14 rotatably installed inside the crushing box 1 through a bearing.

[0033] The outer side of the rotating shaft 14 is located inside the crushing box 1 and is fixedly sleeved with two symmetrically distributed fixing seats 15, and the two fixing seats 15 are respectively located on the lower sides of the two supporting rails 5. Two symmetrically distributed levers 16 are fixedly embedded on the outer side of the fixing seat 15. A hemispherical portion 17 is provided at one end of the lever 16 away from the fixing seat 15, and the lever 16 is in rotational contact with the block 11 through the hemispherical portion 17. The hemispherical portion 17 can reduce the friction between the lever 16 and the block 11. The right end of the rotating shaft 14 is fixedly connected with a dual-axis motor 13, and the dual-axis motor 13 is located on the right side of the crushing box 1.

[0034] Working principle: When mixing livestock feed, the personnel first put the feed at the feed inlet of the primary crushing mechanism in the crushing box 1. The primary crushing mechanism crushes various feeds, which can improve the degree of feed refinement in the later mixing. The crushed feed will fall on the inclined mesh plate 4, and the dual-axis motor 13 drives the rotating shaft 14 to rotate. During the rotation of the lever 16 and the rotating shaft 14, the lever 16 will resist the block 11, and drive the block 11 and the inclined mesh plate 4 to move forward during the rotation. At this time, the spring 9 will be gradually compressed, and when the lever 16 rotates out of the block 11, the inclined mesh plate 4 will move back and forth under the drive of the compressed elastic force of the spring 9, and reciprocate in this way, which is conducive to making the inclined mesh plate 4 swing back and forth repeatedly, and is conducive to accelerating the screening efficiency of the inclined mesh plate 4 for the crushed feed, and the feed fiber that cannot pass through the inclined mesh plate 4 can move to the lower end of the inclined mesh plate 4, which can effectively prevent the fiber in the feed from clogging the through hole of the inclined mesh plate 4;

[0035] The feed falls directly into the mixing bin at the lower end of the crushing box 1 through the tilted net plate 4, and the stirring mechanism in the mixing bin stirs and mixes the various crushed feeds.

[0036] Example 2: Please refer to Figure 2 This embodiment further explains Example 1. The structure of the primary crushing mechanism is the same as that of the secondary crushing mechanism. The secondary crushing mechanism includes a crushing roller 1 35 and a crushing roller 2 36 which are rotatably connected to the protection box 2 through a bearing. The blades of the crushing roller 1 35 and the crushing roller 2 36 are staggered with each other. The crushing roller 1 35 and the crushing roller 2 36 with staggered blades can crush the feed. The rear end of the crushing roller 2 36 is located on the outside of the protection box 2 and is fixedly connected to a drive motor 37, and the drive motor 37 is fixedly connected to the protection box 2. The front ends of the crushing roller 1 35 and the crushing roller 2 36 are located on the outside of the protection box 2 and are fixedly installed with gears 38, and the two gears 38 are meshed with each other.

[0037] In this embodiment: the feed fibers that cannot pass through the inclined mesh disk 4 will be transmitted by the inclined mesh disk 4 to between the crushing roller 1 35 and the crushing roller 2 36 in the protective box 2. Under the condition that the two gears 38 are meshed with each other, when the driving motor 37 drives the crushing roller 2 36 to rotate counterclockwise, the crushing roller 1 35 will rotate clockwise under the action of the two gears 38. Since the blades of the crushing roller 1 35 and the crushing roller 2 36 are staggered with each other, the feed fibers that cannot pass through the inclined mesh disk 4 will be further crushed by the crushing roller 1 35 and the crushing roller 2 36.

[0038] Example 3: Please refer to Figure 4 , Figure 7 , Figure 8 This embodiment further explains the first embodiment. The material guiding mechanism includes an air duct 18 installed inside the crushing box 1 and located at the lower side of the rotating shaft 14. A cover pipe 19 is fixedly installed on the right side of the crushing box 1, and the cover pipe 19 is sleeved on the outer side of the air duct 18. The dual-axis motor 13 is fixedly connected to the cover pipe 19. A support frame 20 is fixedly installed inside the cover pipe 19. The support frame 20 is in a circular grid shape and can protect the impeller 21. The impeller 21 is installed on the left side of the support frame 20 inside the cover pipe 19, and the positioning shaft of the impeller 21 is rotatably connected to the support frame 20 through a bearing.

[0039] A conduit 22 is installed on the upper side of the air duct 18, and a plurality of positioning seats 23 are fixedly sleeved on the outer side of the conduit 22, and the plurality of positioning seats 23 are fixedly connected to the air duct 18. A plurality of spray heads 24 interconnected with the conduit 22 are fixedly installed on the outer side of the conduit 22, and the spray heads 24 can add water to the mixed feed, and the spray heads 24 penetrate the air duct 18 and are located inside the air duct 18.

[0040] The air duct 18 is in a "V" shape, and a through groove 25 is provided on the lower side of the air duct 18 corresponding to the sprinkler head 24. Two symmetrically distributed flexible support plates 26 are fixedly sleeved on the outer side of the air duct 18, and the outer circles of the two flexible support plates 26 are fixedly adhered to the left and right side walls of the crushing box 1 respectively. The flexible support plates 26 can support the air duct 18 to generate larger vibrations. The impeller 21 positioning shaft and the right end of the dual-axis motor 13 are fixedly sleeved with a synchronous wheel 27, and a synchronous belt 28 is installed on the outer side of the synchronous wheel 27.

[0041] In this embodiment: in the process of the dual-axis motor 13 driving the rotating shaft 14 to rotate, the dual-axis motor 13 drives the impeller 21 to rotate through the synchronous wheel 27 and the synchronous belt 28. After the feed fiber is crushed by the secondary crushing mechanism and falls into the guide hopper 3, it will be sucked into the air duct 18 by the impeller 21. At the same time, the spray head 24 in the air duct 18 sprays water into the mixing bin through the through groove 25 to increase the wettability of the mixed feed in the mixing bin. When the gas carries the feed fiber through the spray head 24, the liquid sprayed by the spray head 24 will adhere to the feed fiber, so that the feed fiber will settle into the mixing bin through the through groove 25, which is conducive to the diffusion of the feed fiber after the secondary crushing in the middle of the mixing bin, avoiding the accumulation of the feed fiber after the secondary crushing on the left side of the mixing bin, and facilitating the uniform mixing of the feed fiber after the secondary crushing with other feeds.

[0042] Example 4: Please refer to Figure 7 This embodiment further explains the second embodiment. A connecting assembly is installed between the impeller 21 and the air duct 18. The connecting assembly includes a connecting pipe 29 fixedly sleeved on the right end of the air duct 18. A connecting shaft 30 is fixedly embedded at the center of one side of the impeller 21 close to the air duct 18. A fixing seat 21 is fixedly sleeved on the outer side of the connecting shaft 30. Two symmetrically distributed metal springs 32 are fixedly installed on the outer side of the fixing seat 21. The metal springs 32 have strong bending performance.

[0043] One end of the metal spring 32 away from the fixing seat 31 is fixedly connected to a steel ball 33, and a plurality of baffles 34 equidistantly distributed in a circle are fixedly installed inside the connecting tube 29. The connecting tube 29 and the baffles 34 are both made of metal, and the distance between two adjacent baffles 34 is greater than the diameter of the steel ball 33. The connection between the steel ball 33 and the plurality of baffles 34 is a sliding contact.

[0044] The structure of the primary crushing mechanism is the same as that of the secondary crushing mechanism. The secondary crushing mechanism includes a crushing roller 1 35 and a crushing roller 2 36 which are rotatably connected to the protective box 2 through a bearing. The blades of the crushing roller 1 35 and the crushing roller 2 36 are staggered with each other. The crushing roller 1 35 and the crushing roller 2 36 with staggered blades can crush the feed. The rear end of the crushing roller 2 36 is located on the outside of the protective box 2 and is fixedly connected to a drive motor 37, and the drive motor 37 is fixedly connected to the protective box 2. The front ends of the crushing roller 1 35 and the crushing roller 2 36 are located on the outside of the protective box 2 and are fixedly installed with gears 38, and the two gears 38 are meshed with each other.

[0045] In the present embodiment, during the rotation of the impeller 21, the two steel balls 33 are driven to rotate via the connecting shaft 30. Since the metal spring sheet 32 ​​has a strong bending performance, the two steel balls 33 will slide in contact with the multiple baffles 34 during the rotation. During the sliding contact between the steel balls 33 and the multiple baffles 34, the connecting pipe 29 and the air duct 18 will vibrate continuously. Since the air duct 18 is in a "V" shape, when the air duct 18 vibrates continuously, the feed fibers wetted by the liquid and adhered to the inner wall of the air duct 18 can be vibrated to the through groove 25, and finally discharged from the air duct 18 through the through groove 25 and fall into the mixing bin, which can effectively prevent the feed fibers from adhering to the inner wall of the air duct 18 after drying, and prevent the feed fibers from clogging the air duct 18 in the later stage. In addition, during the vibration of the air duct 18, the feed falling on the air duct 18 and the conduit 22 can also be vibrated into the mixing bin.
