The rotating disk 6 drives the pushing block 14 to move up and down, so that the moving rod 18 slides inside the other lifting hole 12. The tension spring 16 drives the pushing block 14 to move upward, so that the first screening frame 9 and the second screening frame 20 vibrate up and down. The material is poured into the interior of the first screening frame 9 through the feed port 3. The material is screened by the first screening frame 9 and the second screening frame 20.
