Chiseling, polishing and dust removing device in ballastless track construction

The invention belongs to the technical field of ballastless track construction, and particularly relates to a chiseling, polishing and dust removing device in ballastless track construction, and provides the following scheme that the chiseling, polishing and dust removing device comprises a base and an adjusting frame, an adjusting groove is formed in the outer wall of the adjusting frame, sliding blocks are slidably connected to the inner wall of the adjusting groove at equal intervals, a motor plate is fixedly connected to the outer wall of each sliding block, and the outer walls of the opposite sides of every two adjacent sliding blocks are fixedly connected with the same connecting rod. By arranging a dust suction pump, collecting plates, hollow circulating plates and dust suction holes, in the process of polishing the inner wall of a dent, the dust suction pump is started, the dust suction pump transmits suction force into all the collecting plates through the hollow circulating plates, the suction force
