A method for crushing automobile plastic parts according to claims 1-9, characterized in that The following steps are involved: S1, crushing the plastic: placing the plastic in the second placing cylinder (103), and then opening the crusher (104) to crush the plastic; S2, transport of materials: turning on the motor (207), the output end of the motor (207) drives the rotating rod (206) to rotate, thereby driving the stirring member (201) to move upward, so that the trigger block (203) rises into the limiting groove (501), so that the moving block (502a) moves horizontally, thereby driving the opening and closing plate (502d) to open, so that the material discharge chute (502f) opens, and the plastic inside falls into the cleaning cylinder (401); S3, fixing the device: turning on the motor (207), the motor (207) drives the stirring member (201) to move downward via the rotating rod (206), so that the toothed plate (202) drives the gear (304a) to rotate, and then drives the threaded rod (304c) to move via the sleeve (304b), so that the second fixing plate (304f) pops out, thereby fixing the cleaning cylinder (401); S4, material cleaning: turning on the motor (207) to drive the agitator (201a) to rotate, so that the first agitator rod (201b) cleans the plastic; after the cleaning is completed, turning on the motor (207) in the reverse direction to retract the second fixed plate (304f), and then driving the cleaning cylinder (401) to move upward through the agitator (201a); S5. Material screening: The crushed plastic enters the storage tank (407a) through the feed port (407c), and then the motor (207) is turned on to drive the cleaning cylinder (401) to rotate, and the second meshing plate (406d) is driven to rotate through the first meshing plate (406a), and the rotating ring (406c) is driven to rotate, and then the crushed plastic is moved through the second stirring rod (406e). Small plastic will fall to the next process through the discharge chute (502f). After the screening is completed, the box door (407d) is opened for the plastic that has not been completely crushed, and the plastic can be taken out for crushing again.
