Referring to fig. 1, 3 and 4, in the screening process, when in a continuous feeding working state, the uppermost screening work is required to be completed first, and then the next screening work is performed, so that in order to maintain the continuity of the work and simultaneously improve the energy utilization efficiency of the motor 2, if the working efficiency of the upper screening plate 6 is higher, when the screening plate 6 rotates faster, the upper screening work is required to be completed first, when the rotating shaft 3 rotates, due to the radius of the upper driving wheel 4 being larger than that of the lower driving wheel 4, when the angular speeds of the upper driving wheel 4 and the lower driving wheel are consistent, the radius of the upper driving wheel 4 is larger, so that the upper protection ring 7 and the screening plate 6 rotate faster.

Referring to fig. 4, the screening plates 6 are all inclined, and the guard rings 7 are all horizontally arranged, so that in general, if the rotation speed is high, the material is always stacked at one position under the action of centrifugal force, and when the obliquely arranged screening plates 6 rotate on the screening plates 6, the material always moves towards the lower side of the screening plates 6, so that the action of the centrifugal force is reduced.

Referring to fig. 1-3, the driving wheel 4 is meshed with the protection ring 7, racks are arranged on the peripheral surface of the protection ring 7, and the driving wheel 4 is meshed with the protection ring 7 to drive the driving wheel 4 to rotate under the action of the driving wheel 4, so that the linear speeds of the driving wheel 4 and the protection ring 7 are the same.
