[0028] Please refer to Figure 2 and Figure 3 , a connecting ring 11 is installed at the lower end inside the housing 1, and the connecting ring 11 is in threaded fit connection with the housing 1.
[0029] Please refer to Figure 2 and Figure 3 , a conical shell 12 is installed at the upper end of the connecting ring 11 through an inner frame, a vibrator 13 is installed at the lower end of the conical shell 12, and the vibrator 13 is used to make the filter screen 14 vibrate.
[0030] Please refer to Figure 2 and Figure 3 , a filter screen 14 is arranged outside the conical shell 12, and the filter screen 14 is fixedly connected with the conical shell 12.
[0031] Please refer to Figure 1 and Figure 2 , a steering gear 16 is installed on one side outside the top cover 2, an L-shaped connecting rod 17 is installed at the output end of the steering gear 16, and the steering gear 16 is used to control the flipping of the L-shaped connecting rod 17.

[0033] This solution: Pour the raw materials into the housing 1 through the feed hopper 15. Start the drive motor 5 to make the crushing knife 9 rotate. The raw materials are crushed inside the crushing ring 8 under the rotation of the crushing knife 9. After being crushed, the raw materials fall downward to the crushing cone 10 and are further crushed by the crushing cone 10 to improve the degree of crushing of the raw materials. Then, they fall downward to the filter screen 14 and pass through it. Start the vibrator 13 to make the filter screen 14 vibrate accordingly to improve the filtering effect.
