[0015] Next, the technical solutions in the embodiments will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection.

[0016] In the description of the embodiments, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the embodiments and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the embodiments.

[0017] The existing additive raw material crushing device generally adopts the method of mutual meshing of two crushing gears to realize the crushing treatment of feed additive raw materials. However, in this crushing method, on the one hand, since the crushing treatment is only achieved by the one-way rotation and meshing of the meshing gears, the crushing effect is poor. On the other hand, since the spacing between the meshing crushing gears cannot be adjusted, it is difficult to clean up after the crushing is completed.

[0018] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, the embodiment of the present invention provides a feed additive raw material crushing device, including a crushing box body 1, a meshing crushing device 2, a spacing adjustment device 3, a follow-up reciprocating device 4, and an adjustable force application device 5.

[0019] Among them, the meshing and crushing device 2 is movably arranged in the crushing box body 1. Through the meshing action between the two crushing gears, the additive raw materials are crushed. At the same time, the relative sliding between the two crushing gears can be used to increase the shearing and crushing force. Through the action of the shearing and crushing force generated by the relative sliding, the further crushing of the additive raw materials is realized, and the crushing effect is good. It includes a driving crushing gear 6 and a driven crushing gear 7, and the driving crushing gear 6 and the driven crushing gear 7 are meshingly connected and configured for the crushing operation of the additive raw materials.

[0020] The follower reciprocating device 4 is fixedly arranged on the crushing box body 1 and can drive the driving crushing gear 6 to reciprocate and slide on the driven crushing gear 7, increasing the acting force of shearing and crushing for the crushing operation and improving the crushing effect. The follower reciprocating device 4 is arranged below the meshing and crushing device 2 and includes a reciprocating driving frame 8. The reciprocating driving frame 8 is power-transmission connected to the meshing and crushing device 2 and is configured to drive the driving crushing gear 6 to reciprocate and slide.

[0021] The spacing adjustment device 3 is fixedly arranged on the crushing box body 1. The spacing adjustment device 3 is rotationally connected to the meshing and crushing device 2 and is configured to adjust the spacing between the crushing gears. By adjusting the spacing between the driving crushing gear 6 and the driven crushing gear 7, it is convenient to clean the crushing device after the crushing operation.

[0022] The adjustable force application device 5 is fixedly arranged on the spacing adjustment device 3 and is configured to adjust the magnitude of the rotational damping of the driven crushing gear 7. By adjusting the magnitude of the rotational damping of the driven crushing gear 7, the meshing acting force and the sliding shearing acting force between the driving crushing gear 6 and the driven crushing gear 7 can be changed, and thus the crushing degree of the additive raw materials can be adjusted.

[0023] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, in some embodiments, the meshing and crushing device 2 further includes a crushing motor 9 and a fixed frame 10. The fixed frame 10 slidably penetrates through the side wall of the crushing box body 1. The crushing motor 9 is fixedly arranged on the fixed frame 10. The gear shaft of the driving crushing gear 6 slidably penetrates through the side wall of the crushing box body 1, and the gear shaft of the driving crushing gear 6 is rotatably arranged on the fixed frame 10. The crushing motor 9 is power-connected to the driving crushing gear 6. The crushing motor 9 drives the driving crushing gear 6 to rotate, and at the same time, the fixed frame 10 and the driving crushing gear 6 can synchronously reciprocate and slide on the crushing box body 1.

[0024] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, in some embodiments, a sliding block 11 is rotatably fitted on the gear shaft of the driven crushing gear 7. The sliding block 11 is symmetrically arranged with respect to the central plane of the driven crushing gear 7. The sliding block 11 is slidably arranged on the side wall of the crushing box body 1, so that the driven crushing gear 7 can slide on the crushing box body 1, facilitating the adjustment of the position.

[0025] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown in [relevant figures], in some embodiments, the follower reciprocating device 4 further includes a driving cylinder 12, a driving bevel gear 13 and a transmission shaft 14. The reciprocating driving frame 8 is slidably penetrated through the side wall of the crushing box body 1. A driving rack 15 is fixedly arranged on the inner side wall of the reciprocating driving frame 8. The driving rack 15 is symmetrically arranged with respect to the central plane of the reciprocating driving frame 8. The driving cylinder 12 is fixedly arranged on the outer side wall of the crushing box body 1. The extending end of the driving cylinder 12 is fixedly connected with the reciprocating driving frame 8. The driving cylinder 12 can drive the reciprocating driving frame 8 to reciprocate on the crushing box body 1 to adjust the position of the reciprocating driving frame 8.

[0026] The driving bevel gear 13 is fixedly arranged on the gear shaft of the driving crushing gear 6. The transmission shaft 14 is rotatably penetrated through the bottom wall of the fixed frame 10. A driven bevel gear 16 is fixedly arranged at one end of the transmission shaft 14. The driven bevel gear 16 is meshed and connected with the driving bevel gear 13. A reciprocating gear 17 is fixedly arranged at the other end of the transmission shaft 14. The reciprocating gear 17 is meshed and connected with the driving rack 15. The driving bevel gear 13 rotates with the driving crushing gear 6 and transmits power to the reciprocating gear 17. Through the meshing movement of the reciprocating gear 17 and the driving rack 15, the driving crushing gear 6 is driven to make a sliding movement. When the position of the reciprocating driving frame 8 is adjusted by the driving cylinder 12, the reciprocating gear 17 can be meshed with another driving rack 15, thereby driving the driving crushing gear 6 to slide in the reverse direction. By repeating the above actions, the reciprocating sliding of the driving crushing gear 6 can be realized.

[0027] As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in [relevant figures], in some embodiments, the spacing adjustment device 3 includes an adjustment cylinder 18. The adjustment cylinder 18 is fixedly arranged on the outer side wall of the crushing box body 1. The extending end of the adjustment cylinder 18 is slidably penetrated through the side wall of the crushing box body 1. An adjustment frame 19 is fixedly arranged at the extending end of the adjustment cylinder 18. The adjustment frame 19 is rotatably connected with the gear shaft of the driven crushing gear 7. The adjustment cylinder 18 can drive the driven crushing gear 7 to slide on the crushing box body, thereby adjusting the spacing between the driving crushing gear 6 and the driven crushing gear 7, facilitating the cleaning and maintenance of the equipment after the crushing operation.

[0028] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 6 shown, in some embodiments, the adjustable force - applying device 5 includes a fixing plate 20 and a force - applying gear 21. The force - applying gear 21 is fixedly arranged on the gear shaft of the driven crushing gear 7. The fixing plate 20 is fixedly arranged on the adjustment frame 19. A fixing rod 22 is fixedly arranged on the fixing plate 20. A force - applying rod 23 is rotatably arranged on the fixing rod 22. One end of the force - applying rod 23 is fixedly provided with a force - applying block 24. The force - applying block 24 is cooperatively arranged with the force - applying gear 21. The force - applying block 24 can be pressed into the tooth groove of the force - applying gear 21. The other end of the force - applying rod 23 is fixedly provided with an adjusting spring 25. An adjusting bolt 26 is in threaded cooperation with the fixing plate 20. An adjusting plate 27 is rotatably arranged on the adjusting bolt 26. The adjusting plate 27 is fixedly connected with the adjusting spring 25.

[0029] Under the elastic force of the adjusting spring 25, the force - applying block 24 on the force - applying rod 23 is pressed against the force - applying gear 21, which can apply a resistance to the rotation of the driven crushing gear 7. By adjusting the height of the adjusting plate 27, the compression amount of the adjusting spring 25 can be adjusted, and then the rotation resistance can be adjusted. When the rotation force is greater than the rotation resistance, rotation can occur, and the force - applying block 24 enters another tooth groove for continuous force application, thereby adding an adjustable interaction force for the meshing of the driving crushing gear 6 and the driven crushing gear 7 to adjust the degree of crushing.

[0030] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, in some embodiments, a storage box 28 is connected to the bottom of the crushing box body 1. The storage box 28 is used to store the crushed additive raw materials. A feeding box 29 is connected to the upper part of the crushing box body 1. The feeding box 29 is used for feeding the additive raw materials. A feeding shaft 30 is rotatably arranged in the feeding box 29. Feeding rods 31 are fixedly arranged on the feeding shaft 30. Multiple groups of feeding rods 31 are provided. A feeding motor 32 is fixedly arranged on the outer side wall of the feeding box 29. The feeding motor 32 is power - connected to the feeding shaft 30. The feeding motor 32 drives the feeding shaft 30 to rotate. Under the action of multiple groups of feeding rods 31, the feeding speed can be increased and the blockage of the feeding box 29 can be avoided.

[0031] The above - mentioned are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
