Preferably, the lower surface of the end part of the first screen 3 is provided with a first bulge 3.1, the upper surface of the end part of the second screen 4 is provided with a second bulge 4.1, a rotating disc 13 is arranged between the first bulge 3.1 and the second bulge 4.1, the outer ring of the rotating disc 13 is uniformly provided with a plurality of collision bulges 14 matched with the first bulge 3.1 and the second bulge 4.1, and the center of the rotating disc 13 is connected with an output shaft of a motor 15. So designed, when the motor 15 is operated, the rotating disk 13 is rotated, so that the collision protrusions 14 are continuously brought into contact with and collide with the first protrusions 3.1 and the second protrusions 4.1, thereby vibrating the first screen 3 and the second screen 4, thereby performing a screening process.

Preferably, the motor 15 is fixed to the support frame 17 by a connection plate 16.

Preferably, the first telescopic mechanism 10 and the second telescopic mechanism 12 are electric push rods or pneumatic telescopic rod structures, and both the first telescopic mechanism 10 and the second telescopic mechanism 12 are fixed on the support rod 18.

Preferably, the upper surface and the lower surface of the first screen 3 are provided with first compression springs 5, and the upper surface and the lower surface of the second screen 4 are provided with second compression springs 7. After the compression spring is arranged, the screen can vibrate up and down in a reciprocating manner, and the vibration process is more stable.
