The first protective cover 21 provides shielding during stripping to prevent asphalt waste from splashing. The stripping thickness of the asphalt pavement can be adjusted by adjusting the component 22, so that layered stripping can be achieved. The output shaft of the second motor 304 rotates to drive the cleaning roller 305 to rotate in the inner cavity of the second protective cover 302. When the second protective cover 302 rotates, the stripped asphalt waste can be cleaned and the asphalt waste can be diverted to the inner cavity of the collection box 301 through the inclined plate 303 for collection.
