When the first rotating shaft 12 is rotated, the gear 13 meshes with a pair of toothed plates 14.

A first partition 25 is installed inside the spiral plate 1, and a second groove 26 is formed on the side opposite to the spiral plate 1. A sliding column 27 and a spring 28 are also installed. When the power unit drives the screening plate 4, the screening plate 4 vibrates due to the spring 28 and the sliding column 27, thus completing the screening of the internal material. A first motor 29 is fixed to one side of the support column 3. When the operator starts the first motor 29, the protrusions 32 on the turntable 31 sequentially contact the screening plate 4, lifting it up.
