Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment 1:

A second mixing shaft 161 is arranged on the driven gear 16. The second mixing shaft 161 penetrates through the mixing bin 12 and is fixedly connected to a second mixing blade 162. A driving wheel 17 is arranged on the driven gear 16. A transmission belt 18 is arranged on the driving wheel 17. The transmission belt 18 is drivingly connected to a crushing assembly 3;

[0023] A screening assembly 2 is arranged inside the mounting frame 1. The screening assembly 2 includes a screening frame 21. A screen mesh 22 is arranged inside the screening frame 21. A plurality of connecting platforms 23 are arranged outside the screening frame 21. The other ends of the connecting platforms 23 are fixedly connected to the inner wall of the mounting frame 1. A discharge opening 24 is formed in the screen mesh 22. The crushing assembly 3 is fixedly connected to the discharge opening 24.

[0024] As a preferred technical solution in this embodiment: In the actual use process, the staff can control the driving motor 11 to drive the reduction gear 13 to rotate. During the rotation of the reduction gear 13, it can effectively drive the first stirring shaft 14 and the transmission gear 15 to rotate. During the rotation of the first stirring shaft 14, it can drive the first stirring blades 141 to rotate. During the transmission of the transmission gear 15, it can drive the driven gear 16 to produce a reverse rotation effect. During the rotation of the driven gear 16, it can drive the second stirring shaft 161 to make the second stirring blades 162 rotate in the opposite direction to the first stirring blades 141, thus ensuring that the raw materials can be fully stirred.

[0025] When adding raw materials into the stirring bin 12, the staff can pour the raw materials into the stirring bin 12 from the feeding port 19. The raw materials will fall on the screen 22 under the action of gravity. At the same time, the staff can start the vibration motor 25 to drive the screen 22 to vibrate, achieving the effect of screening the raw materials. The screened raw materials will fall into the crushing assembly 3 through the material dropping port 24, thus achieving the effect of crushing the agglomerated or large-particle raw materials.

[0026] It should be noted that the screening frame 21 in the stirring bin 12 in this embodiment should be inclined, so as to ensure that the screened raw materials can fall into the material dropping port 24.

[0027] Embodiment Two:

[0028] Please refer to Figure 4 , in order to achieve the effect of crushing the screened raw materials, the crushing assembly 3 in this embodiment includes a crushing frame 31. The top of the crushing frame 31 is fixedly connected with a bellows tube 32, and the top of the bellows tube 32 is fixedly connected to the material dropping port 24. A first rolling roller 35 and a second rolling roller 36 are rotatably connected in the crushing frame 31. A first connecting shaft 33 is arranged on the first rolling roller 35, and a second connecting shaft 34 is arranged on the second rolling roller 36. Both the first connecting shaft 33 and the second connecting shaft 34 penetrate the crushing frame 31 and are respectively fixedly connected with a first linkage gear 37 and a second linkage gear 38, and the first linkage gear 37 and the second linkage gear 38 are meshed with each other. The point is that a driven wheel 39 is arranged on the first linkage gear 37, and the driven wheel 39 is meshed with the transmission belt 18.

[0029] As a preferred technical solution in this embodiment: During actual use, when the staff controls the driving motor 11 to drive the driven gear 16 to rotate, the driven gear 16 can drive the driving wheel 17 to rotate. During the rotation of the driving wheel 17, it can drive the transmission belt 18 to make the driven wheel 39 rotate. During the rotation of the driven wheel 39, it can drive the first linkage gear 37 to rotate. When the first linkage gear 37 rotates, it can drive the second linkage gear 38 to rotate in the reverse direction, so that the first rolling roller 35 and the second rolling roller 36 can rotate in the reverse direction during use, ensuring that it can achieve the effect of crushing the raw materials.

[0030] By providing the bellows tube 32, it can effectively play a role in connecting the crushing frame 31 and the material dropping port 24 during use, so that the connection relationship between it and the crushing frame 31 will not be affected during the vibration of the screening frame 21.

[0031] The working principle of the above embodiment is as follows:

[0032] 1. As a preferred technical solution in this embodiment, during actual use, the staff can control the driving motor 11 to drive the reduction gear 13 to rotate. During the rotation of the reduction gear 13, it can effectively drive the first stirring shaft 14 and the transmission gear 15 to rotate. During the rotation of the first stirring shaft 14, it can drive the first stirring blade 141 to rotate. During the transmission of the transmission gear 15, it can drive the driven gear 16 to rotate in the reverse direction. During the rotation of the driven gear 16, it can drive the second stirring shaft 161 to make the second stirring blade 162 rotate in the reverse direction with the first stirring blade 141, thus ensuring that it can fully stir the raw materials.

[0033] When adding raw materials into the stirring bin 12, the staff can pour the raw materials into the stirring bin 12 from the feeding port 19. The raw materials will fall on the screen 22 under the action of gravity. At the same time, the staff can start the vibration motor 25 to drive the screen 22 to vibrate, achieving the effect of screening the raw materials. The raw materials after screening will fall into the crushing assembly 3 through the material dropping port 24, thus achieving the effect of crushing the caked or large-particle raw materials.

[0034] II. When the staff controls the driving motor 11 to drive the driven gear 16 to rotate, the driven gear 16 can drive the driving wheel 17 to rotate. During the rotation of the driving wheel 17, it can drive the transmission belt 18 to make the driven wheel 39 rotate. During the rotation of the driven wheel 39, it can drive the first linkage gear 37 to rotate. When the first linkage gear 37 rotates, it can drive the second linkage gear 38 to rotate in the reverse direction, so that the first rolling roller 35 and the second rolling roller 36 can rotate in the reverse direction during use, ensuring that they can achieve the effect of crushing the raw materials falling into the crushing frame 31 after screening.
