The fixed rod 503 drives the connecting rod 701 to reciprocate, and the connecting rod 701 collides with the swing rod 702 during the reciprocating movement. When the connecting rod 701 passes over the swing rod 702, the swing rod 702 is reset by the torsion spring, thereby realizing the reciprocating swing of the swing rod 702 and driving the cleaning head 703 to clean the road surface, thereby improving the adhesion between the ground asphalt and the base layer, increasing the stability of the road surface, and further improving the work quality.
