When the device works, with the rotation of the two incomplete gears, the strip-shaped teeth on the two sides of the sliding shaft are meshed with the corresponding incomplete gears intermittently and alternately, so that the sliding shaft is driven to axially reciprocate. The time for the tool to stay after returning can be determined according to the number of gear teeth of the incomplete gear, so that the tool is quite convenient.
Meanwhile, on the basis of the structure, the dredging tool of the embodiment further comprises a bottom frame, a hopper, a baffle frame and a driving mechanism, wherein the bottom frame is of a rectangular structure, the hopper is covered on side beams of the two length directions of the bottom frame, the hopper is of a channel steel-shaped structure, an opening is upward, the rear end of the bottom of the hopper is hinged to the side beams through a hinge shaft, and the front end of the hopper is connected with an inclined hopper which inclines downwards. Meanwhile, the baffle frame comprises a tail plate which is vertically arranged, a pair of connecting rods are vertically fixedly connected to the surface of one side of the hopper, the two connecting rods are respectively located above the two side beams, the connecting rods are hinged to the outer side wall of the hopper by means of the middle position of the connecting rods, and the free ends of the connecting rods face the inclined hopper.
