The working principle and use process of this utility model:

When in use, the lock is opened, the cover is rotated, and the material is added to the feeding bin 21. The material is simply screened by the screen 23 to make the material with too large volume enter the crushing cylinder 24, and the second motor 26 is started to drive the crushing roller 25 to rotate, so that the crushing roller 25 cooperates with the crushing cylinder 24 to crush the material. The crushed material falls into the feeding bin 21 along the feeding chute 28, and is mixed with the material screened by the screen 23, and is sent to the inside of the crushing cylinder 1 along the feeding pipe 22. After the feeding is completed, the cover is fixed to the top of the feeding bin 21 by the lock, so that the cover blocks the feeding bin 21;

The first motor 5 is started to drive the blade 7 to rotate, so that the blade 7 crushes the material in the crushing barrel 1, and the material adheres to the inside and bottom of the crushing barrel 1. The fan 10 is started to blow air into the transfer box 11, so that the internal air pressure of the transfer box 11 increases, and the air inside itself is dispersed into the first air duct 13 and the second air duct 14. The air in the first air duct 13 is introduced into the inside of the crushing barrel 1 along the rectangular frame plate 8, which will blow up the material attached to the inner wall of the crushing barrel 1. The air in the second air duct 14 is introduced into the discharge pipe 4, which will lift up the material in the lower hopper 3 and the discharge pipe 4, so that the material can be better crushed by the blade 7 under the drive of the airflow. The excess air in the crushing barrel 1 is filtered by the second filter and then discharged to prevent the internal air pressure of the crushing barrel 1 from being too high.

After a period of time, the material is crushed and the electric push rod 19 is controlled to extend, so that the electric push rod 19 drives the plug 16 to move downward, forcing the plug 16 to no longer block the discharge pipe 4, and the crushed material in the crushing barrel 1 is discharged along the discharge pipe 4. During this process, the third motor can be controlled to drive the spiral auger 18 to rotate, helping the material to be discharged along the discharge pipe 4 faster and better.
