[0020] 2. When the waste is put into the box for crushing, the generated dust will fall on the inner wall of the box. If it is not cleaned in time, the dust will enter the gaps of bearings and other parts, which will cause the rotating parts to get stuck after a long time. At this time, the rotation of the first motor can drive the cam to rotate, and the rotation of the cam drives the piston to reciprocate in the cylinder. Through the one-way passing characteristic of the one-way valve, the external gas is drawn into and pumped out of the cylinder, and the gas is sent to the air blowing pipe inside the box. The gas is sprayed out through the air blowing pipe to remove dust from the inner wall of the box to prevent dust from entering the gaps of parts and causing them to get stuck;

[0021] 3. Put large pieces of waste into the box, then start the first motor, the rotation of the first motor drives the second gear to rotate, and the second gear meshes with the first gear, driving the crushing roller to rotate, squeezing the large pieces of waste into pieces of equal size, so as to facilitate the subsequent crushing of the waste more evenly and facilitate subsequent processing and treatment.
