[0007] As a preferred technical solution of the utility model, the top wall of the box body is provided with a feeding port for feeding materials into the box body.

[0008] As a preferred technical solution of the utility model, an electric push rod is arranged on the top wall of the box body, and a hammer plate is connected to the free end of the electric push rod.

[0009] As a preferred technical solution of the present utility model, the side wall of the box body is provided with a dust inlet, and the side wall of the box body is provided with a vacuum cleaner located on one side of the dust inlet.

[0010] As a preferred technical solution of the utility model, three crushing rollers for crushing stones are arranged in the box body and below the screening steel plate, and a discharge port is provided on the bottom wall of the box body and below the crushing rollers.

[0011] As a preferred technical solution of the utility model, a support leg for supporting and fixing the device is fixedly connected to each of the four corners of the bottom wall of the box.

[0012] Compared with the prior art, the utility model can achieve the following beneficial effects:

[0013] The connection plate is moved and adjusted by the coordinated setting of the connecting plate and the screw rod, the toggle teeth are moved and adjusted by the movable and adjusted connecting plate, and the stones accumulated on the screening steel plate are toggled by the movable and adjusted toggle teeth, so that the crushed stones pass through the screening steel plate through the toggle gap and fall between the crushing rollers for a second crushing.
