7. An asphalt processing waste disposal apparatus as claimed in claim 1, wherein: The bottom of the supporting boom (7) is provided with two circular plates, and the two circular plates are respectively clamped on the upper and lower sides of the connecting ear frame (601).

8. An asphalt processing waste disposal apparatus as defined in claim 1, wherein: The bottom end of the moving rod frame (81) is provided with a clamping ring, the clamping ring is clamped in the through hole in the upper inside of the hammer rod (82), the clamping ring on the hammer rod (82) is clamped in the T-shaped groove in the inside of the lifting shaft (5), and the lower outside of the hammer rod (82) is threadedly and tightly connected with a hammer head (801).

9. A method of processing in a bitumen processing waste treatment apparatus according to any one of claims 1 to 8, wherein, The method comprises the following steps: 1) waste shearing: the plastic waste is put into the main cavity (1), the driving motor (301) in the electric control box (2) is started, the driving shaft group (3) drives the moving frame (6) to reciprocate through the incomplete gear on the fixed shaft boom (4), the lifting shaft (5) is moved up and down at the same time, the hammering part (8) is reciprocated to stir, and the motor in the electric control box (2) is started to shear the plastic waste through the blade on the stirring shaft; 2) particle conveying: the plastic waste sheared in the first main cavity (1) is conveyed to the second main cavity (1) through the conveying belt to complete the conveying of the plastic waste particles; 3) adding a compatible agent: when processing PE plastic, maleic anhydride grafted polyethylene compatible agent is added, the addition amount is 3%-5% of the mass of the plastic; when processing PP plastic, maleic anhydride grafted polypropylene compatible agent is added, the addition amount is 4%-6% of the mass of the plastic; when processing PVC plastic, first, epoxy soybean oil dechlorinating agent is added, the addition amount is 8%-10% of the mass of the PVC, and then acrylate compatible agent is added, the addition amount is 5%-7% of the mass of the PVC; 4) waste mixing: the driving motor (301) in the second main cavity (1) is started to rotate, and the plastic waste in the second main cavity (1) is repeatedly hammered and fully mixed with the waste through the intermediate hammer rod (82) according to the same principle as step 1, the reciprocating hammer rods (82) on both sides form different stirring and mixing tracks with the rotating stirring rod, and the waste is fully mixed.
