[0025] When in use, the crankshaft 11 is driven to rotate by the output end of the driving motor 10, so that the rotation of the crankshaft 11 drives the curved neck 12 to rotate around the crankshaft 11, and the curved neck 12 drives the screen 4 to move back and forth through the connecting rod 13, so that the screen 4 separates the powder raw materials on the upper surface. The device is convenient for screening raw materials.
