Under the rotation support of the bearing, the rotating rod drives the eccentric wheel to rotate in situ. Since the shaft hole of the eccentric wheel is biased to one side, the eccentric wheel can produce reciprocating motion when rotating, and continuously beat the slider rhythmically. Because the slider can only move up and down on the inner side of the concave block, the slider moves up and down stably under the guiding effect of the inner support rod and the elastic potential energy of the spring, so that the first screening plate and the second screening plate are coordinated with each other, The first screening plate and the second screening plate vibrate back and forth up and down with the corresponding hinged seats as the axis. Because the first screening plate and the second screening plate are inclined, the material first passes through the first screening of the first screening plate, the coarse material is discharged from the first outlet, and the fine material falls onto the second screening plate for further screening, the fine material is discharged from the second outlet, and the finer material falls and is discharged from the third outlet. During screening, the air pump can be started to absorb the dust generated by screening in the screening box and pass through the dust suction pipe into the air intake pipe. At this time, the air will continue to be pumped away and discharged from the exhaust pipe. The dust will be blocked by the filter element and then fall into the dust collecting box along the guide pipe.
