a dredger

Abstract

The invention provides a dredge boat, which belongs to the technical field of boats. The dredge boat comprises a boat body and a dredge pump, wherein an inlet of the dredge pump communicates with one end of a dredge main pipe, a sediment collecting device is arranged on the other end of the dredge main pipe, the sediment collecting device comprises a bypass pipe, two sediment collecting wheels and a driving device for driving the sediment collecting wheels, the bypass pipe is bent, both ends of the bypass pipe communicate with the dredge main pipe, the upper and lower ends of the bypass pipe are positioned between an inlet and an outlet of the dredge main pipe, check valves I are respectively arranged at end openings of the upper and lower ends of the bypass pipe, a piston is connected to the interior of the dredge main pipe in a sliding mode, a piston rod of the piston extends downwards from the dredge main pipe, the piston rod and the two sediment collecting wheels are connected by virtue of a transmission mechanism which enables the piston rod to do a reciprocating motion along with the rotation of the two sediment collecting wheels, and a check valve II is arranged at the inlet of the dredge main pipe. The dredge boat has the advantages of simplicity in control, reliability in operation and the like.

Description

technical field [0001] The invention belongs to the technical field of ships and relates to a dredger. 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 rotating cutter device is oft...

AI Technical Summary

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
