The sorted material is discharged through the discharge pipe in the screening shell, rotate the storage shell, and the material remaining in the storage shell is discharged from the side wall of the screening shell.

[0014] The design of the cone at the bottom of the screening shell facilitates the falling of materials. The discharge pipe arranged at the bottom of the screening shell is made of soft rubber material. The discharge pipe can be directly inserted into the collecting device to facilitate the collection of the sorted materials and prevent the materials from flying around due to wind.

[0016] Through the setting of the sensor, when there is no material falling in the feeding pipe, the sensor transmits the signal to the control module. Under the action of the control module, the motor stops working. When the sensor detects that there is material falling from the feeding pipe, the motor starts working. Under the action of the sensor, the intelligent start and stop of the whole equipment is realized after the material screening is completed, and there is no need to observe the material screening process of the whole equipment in real time.
