[0002] Cutter suction dredging ships are widely used in the treatment of inland rivers and sea channels and port maintenance. Most of the existing cutter suction dredging ships directly use a suction pipe, and then fix a suction pump at one end of the suction pipe. Since the suction pump is It is fixedly connected to the dredging pipe, so that when the dredging depth of such ships is small, the suction pipe of the dredge pump may touch the river bed, hindering the cutting of the reamer, thus affecting the performance of the cutter suction dredger and limiting Application scope of cutter suction dredger

The invention provides a shallow dredging device for a cutter suction dredger. The shallow dredging device comprises a cutter rest, an adjustment pivot, a cutter, a dredging pipe and a steel wire rope, wherein one end of the cutter rest is connected with a dredger body and the other end of the cutter rest is provided with a movable pulley group; one end of the steel wire rope is connected with a winch installed on the dredger body, and the other end of the steel wire rope is connected with the movable pulley group via a fixed pulley at the top of a hanger frame; the cutter is installed on the cutter rest through the adjustment pivot and communicated with one end of the dredging pipe installed on the cutter rest; and one end of the dredging pipe is connected with a dredge pump installed in a pump cabin. By the adoption of the technical scheme of the invention, the operation filed of the dredger is widened, the cutting performance of the cutter of the dredge pump is improved during shallow dredging, the operating stability of the cutter is enhanced, and the operation efficiency of the dredger and the operation capability of a single dredge are improved greatly.
Description
technical field [0001] The invention relates to the technical field of cutter suction dredging ships, in particular to a shallow dredging device for cutter suction dredging ships. Background technique [0002] Cutter suction dredging ships are widely used in the treatment of inland rivers and sea channels and port maintenance. Most of the existing cutter suction dredging ships directly use a suction pipe, and then fix a suction pump at one end of the suction pipe. Since the suction pump is It is fixedly connected to the dredging pipe, so that when the dredging depth of such ships is small, the suction pipe of the dredge pump may touch the river bed, hindering the cutting of the reamer, thus affecting the performance of the cutter suction dredger and limiting Range of use of cutter suction dredgers. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a shallow dredging device for cutter suctio...
