The lower surface of the guide bucket on the shell 4 contacts the seal 2, and the shell 4 and the bucket body 1 are connected by the buffer fixing part 10. The seal 2 can ensure that the shell 4 and the bucket body 1 are tightly connected to prevent material leakage, while the buffer fixing part 10 can effectively absorb vibration and extend the service life of the equipment.

[0021] The pretreatment group 3 includes a shell 4, a feed pipe, a material dispersing cone 5, a filter screen 6, a discharge pipe 8, and a vibration motor 9. The outer side of the shell 4 is connected to the vibration motor 9 through a motor mounting base. The feed pipe is located in the middle of the upper surface of the shell 4. The material dispersing cone 5 is located below the feed pipe and is connected to the inner wall of the shell 4 through three connecting plates. The filter screen 6 is located below the material dispersing cone 5, and the discharge pipe 8 is located in the middle of the filter screen 6. One end of the discharge pipe 8 penetrates the shell 4.

[0022] Specifically, the filter screen 6 is inclined inward in a bucket-shaped structure. With the setting of the material distribution cone 5, the material can be guided to the outermost end of the filter screen 6, thereby increasing the time the material spends on the filter screen 6 and improving the filtration efficiency. At the same time, the vibration generated by the vibration motor 9 is transmitted to the material distribution cone 5 through the connecting plate, so that the material is evenly distributed, avoiding blockage and ensuring a smooth production process.

[0023] This configuration allows the vibrating motor 9 to drive the housing 4 to vibrate, thereby effectively dispersing the material by the material dispersing cone 5. This ensures that the filtration effect of the filter screen 6 is maximized, and the filter screen 6 screens the material, causing fine particles to fall to the bottom of the hopper 1, while larger particles are discharged through the discharge pipe 8. This achieves material grading and improves production efficiency.

[0024] A discharge plate 15 is provided between the material cone 5 and the filter screen 6. A rotating shaft 16 is provided below the discharge plate 15.

[0029] The conical surface of the protective shell 21 can prevent the material from accumulating on the upper surface of the protective shell 21, thereby improving the material utilization rate.

[0030] In this way, the driving motor 24 is started, the power is transmitted to the driving bevel gear 23 through the transmission shaft, the driven bevel gear 22 is rotated by the driving bevel gear 23, and then the rotating shaft 16, the material beating plate 15, and the anti-sticking assembly 17 are driven to work, so as to ensure that the material is evenly beaten and clumped, improve the overall screening effect, prevent the hopper body 1 from being blocked, and prevent the hopper body 1 from being blocked.

[0031] Further, the anti-sticking assembly 17 comprises a hopper body scraper 18 and a hopper mouth scraper 19. The hopper body scraper 18 is arranged on the inner wall of the hopper body 1 and connected with the rotating shaft 16 through a fixed plate. The hopper mouth scraper 19 is arranged on the inner wall of the discharge port of the hopper body 1 and mounted on the lower surface of the rotating shaft 16.

[0032] Specifically, the hopper mouth scraper 19 extends into the discharge port of the hopper body 1 and contacts with the inner wall of the discharge port. The hopper body scraper 18 cooperates with the hopper mouth scraper 19 to effectively remove the adhered material on the inner wall of the hopper body 1 and the inner wall of the discharge port, so as to ensure the smooth discharge of the material, reduce the cleaning time of the equipment, and further improve the production efficiency and equipment stability.
