Cutter suction dredger with improved structure

Abstract

The invention provides a cutter suction dredger with an improved structure, and belongs to the technical field of dredgers. The cutter suction dredger with the improved structure comprises a hull structure, a rotary rod, an installation box and a mud conveying pipe, wherein a mud storage cabin is arranged in the hull structure; a first mud suction pump is arranged on the hull structure and communicates with the mud storage cabin through a pipe; one end of the rotary rod is hinged to the head part of the hull structure; one side of the installation box is fixedly connected with the rotary rod;the installation box comprises a clapboard; the clapboard divides the interior of the installation box into a storage chamber and an equipment chamber; the storage chamber is connected with an inlet of the first mud suction pump through a mud suction header pipe; a second mud suction pump is arranged in the equipment chamber; an outlet of the second mud suction pump is connected with the storage chamber through a pipe; the mud conveying pipe is fixedly connected with the installation box and is connected with an inlet of the second mud suction pump through a flexible pipe; a reamer is arrangedat the lower end of the mud conveying pipe; a sleeve pipe is arranged on the outer side of the mud conveying pipe in a sleeving way; and multiple auxiliary mud suction mechanisms capable of sucking silt are arranged on the sleeve pipe. According to the cutter suction dredger with the improved structure provided by the invention, the reamer can be assisted to quickly suck the silt, so that the working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of dredgers, and relates to a cutter suction dredger with an improved structure. Background technique [0002] The cutter suction dredger uses a rotating reamer to crush the soil at the bottom of the river or seabed, mixes it with cement to form mud, sucks it into the pump body through the dredging pipe, and sends it to the mud discharge area through the mud discharge pipe. [0003] The cutter suction dredger is equipped with a reamer for cutting sediment and rocks at the bottom of the water. The reamer has the characteristics of small cutting area, low speed and small mud inlet, and can cut hard mud layers. [0004] But because the bottom surface is covered with one deck softer silt layer, the work efficiency of above-mentioned reamer is lower. Contents of the invention [0005] The object of the present invention is to solve the above-mentioned problems in the existing technology, and propose a cutter s...
