After the material to be shredded is discharged into the interior of the chassis 1, the external power supply is connected to start the motor 6 to drive the rotating rod 7 to rotate, thereby driving the single-axis roller 9 to rotate, so that the single-axis roller 9 drives the shredding blade 21 to rotate , shredding the material. In the process of shredding the material, dust will be generated. The fan 27 is started to extract the air inside the chassis 1. The extracted air flows from the connecting network 25 through the air extraction box 26 and is discharged from the exhaust network 28. The pumped air flow is used to guide the dust downward to fall back into the chassis 1. When the fan 27 extracts the air inside the chassis 1, the air flow is used to blow the downward inclined blades 36 to swing, thereby driving the movable long rod 35 to rotate. When the air inside the chassis 1 is extracted, the dust will be generated. Dust and shredded materials will adhere to the surface of the connecting net 25, and the motor 6 drives the rotating rod 7 to rotate, thereby driving the wheel 1 8 to rotate. Since the wheel 1 8 is connected to the wheel 2 30 by transmission, the movable rod 29 is rotated by the rotation of the wheel 2 30, so that the connecting ring 31 drives the connecting rod 32 to do circular motion with the movable rod 29 as the axis, and the fixed plate 33 drives the metal brush 34 to wipe the surface of the connecting net 25, and the dust and shredded materials attached to the connecting net 25 are wiped off, thereby ensuring the normal operation of the air extraction and dust induction.
