During the screening process, the cushion block 9 supports one end of the sieve plate 3 to ensure its stability, and the sieve plate 3 screens the material.

[0027] The vibrator 6 is installed on the back wall of the screening box 2 by bolts, and the transmission box 4 is connected to the screening box 2 by screws. The vibrator 6 can drive the screen plate 3 to vibrate, thereby accelerating the screening rate of the device.
