Milling device for transverse crack of highway pavement

Abstract

The utility model discloses a highway pavement transverse crack milling device which comprises a movable plate trailer, the front side and the rear side of the top of the movable plate trailer are fixedly connected with support rods through bolts, the left side and the right side of each support rod are fixedly connected with hollow blocks through bolts, and bearings are installed in inner cavities of the hollow blocks; a bidirectional threaded rod is arranged on the opposite sides of the front hollow block and the rear hollow block, connecting rods are welded to the front end and the rear end of the bidirectional threaded rod, and a motor is started to drive the connecting rods and the bidirectional threaded rod to rotate, so that a sliding block is driven to slide on the surfaces of the bidirectional threaded rod and a guide rod in a reciprocating mode. And the dust collecting machine is used for collecting the chippings and the dust around the movable plate trailer through the dust collecting cover, so that the purposes of collecting the chippings and the dust generated during working of the milling device in a large range and reducing the adverse effects of the chippings and the dust generated by milling on the working environment can be achieved.
