At present, the hydraulic cutter suction dredger is commonly used, and its basic working principle is:
The hydraulic system power provides power to the reamer head. The reamer is used to ream the sand or mud layer at the bottom of the river. The motor drives the sand pump to rotate at a high speed. The sand pump sucks the mud and sand-water mixture from the mud (sand) suction pipe and passes The mud (sand) pipe is transported to the shore.
When the cutter suction vessel is working, the boom lifting winch controls the underwater boom lifting, which can control the cutter suction vessel to suck different depths of silt or sand; both sides of the hull are equipped with traverse winches and anchor piles. When the hull needs to move, the stern of the ship One of the positioning piles is inserted into the sand layer and fixed, and the other positioning pile is lifted, and the cutter suction boat swings from side to side and fan-shaped pumping mud (sand) by moving the winch left and right. The advancement of the cutter suction boat is positioned by two The piles are alternately raised and lowered, which is realized by cooperating with winches on both sides.
The operation process of the articulated suction vessel can complete the work such as sand pumping (draining) and unloading continuously at one time. It is a kind of dredging equipment with high efficiency and low cost.
