In this way, when the swing arm 53 moves to the upper and lower circumferential end points, it can drive the first connecting frame 41 to reciprocate in an arc along the movable shaft 43, so that the conduction roller 42 at the end of the first connecting frame 41 can hit the adjacent surfaces of the first screen plate 3 and the second screen plate 31, so that the surfaces of the two screen plates can be vibrated, thereby causing the crushed materials gathered on the surfaces to vibrate, thereby realizing synchronous conduction when screening the crushed waste on the surfaces of the two groups of screen plates, thereby avoiding the blockage of waste on the surfaces of the two screen plates to a great extent, and improving the overall screening efficiency of the crushed waste.
