Dredger of improved structure

Abstract

The invention provides a dredger of an improved structure and belongs to the technical field of ships. The dredger of the improved structure comprises a ship body and a silt suction pump, an inlet of the silt suction pump communicates with one end of a silt suction main pipe, and a silt collection device is arranged at the other end of the silt suction main pipe. The silt collection device comprises a bypass pipe, two silt collecting wheels and driving devices driving the silt collecting wheels to rotate. The bypass pipe is bent, the two ends of the bypass pipe communicate with the silt suction main pipe, the upper end and the lower end of the bypass pipe are located between an inlet and an outlet of the silt suction main pipe, first one-way valve plates are arranged at the upper end port and the lower end port of the bypass pipe, a piston is connected into the silt suction main pipe in a sliding mode, a piston rod of the piston downwards extends out of the silt suction main pipe, the piston and the two silt collecting wheels are connected through a transmission mechanism which can make the piston rod rotate in a reciprocating mode along with the two silt collecting wheels, a second one-way valve plate is arranged at the inlet of the silt suction main pipe, an energy dissipation box is arranged in a silt bin, and a silt discharge pipe communicates with the energy dissipation box. The dredger has the advantages of being easy to control, more reliable in work and the like.

Description

technical field [0001] The invention belongs to the technical field of ships and relates to a dredger with an improved structure. Background technique [0002] The task of the dredger is to carry out underwater earthwork construction, specifically: digging, widening and cleaning existing channels and ports; excavating new channels, ports and canals; dredging piers, docks, locks and other water It is a sharp tool for blowing sand and reclamation, such as the foundation trench of industrial buildings and throwing the excavated sand into the deep sea or dredging and filling in land depressions to make fields. [0003] The dredger extends the suction main pipe to the surface of the underwater mud layer from the side or stern of the ship, and starts the suction pump in the cabin to suck, transport, load and unload the river bottom sediment to the transport ship or directly to the shore; The sediment layer is deposited and compacted, and it is not easy to be directly sucked. A ro...

Problems solved by technology

The mud-cutter mechanism and the mud-pump mechanism of this kind of sediment collection device are controlled by their own systems, resulting in complex equipment composition and control, and cannot cooperate with each other. For example, when the mud-cutter mechanism fails, the pump suction mud mechanism still works. Inhale a large amount of water and do useless work, or when the pump force suction mechanism fails, the mud cutter mechanism is still working and does useless work, resulting in a waste of energy
