Drag head device allowing silt dragging depth to be regulated

Abstract

The invention discloses a drag head device allowing the silt dragging depth to be regulated, and relates to the technical field of dredgers. The drag head device comprises a drag head device body, a drag-suction device and a hanging bracket. The drag head device body comprises a rotation column, drag heads and an outer ring. The drag-suction device comprises a silt filter device and a silt suctionpipeline. The hanging bracket comprises a supporting frame, a pulley block, a limiting pipe and a fixing device. The pulley block is connected with a ship body through a rope in a rotating manner. Anoutput shaft of a motor is in transmission connection with the rotation column. The rotation column is in clearance fit with the limiting pipe. The fixing device is in clearance fit with the outer ring. The silt filter device is fixed to the inner surface of a notch. A fixing block is arranged on the silt suction pipeline and is fixedly connected with the supporting frame. According to the drag head device, through the effects of the drag head device body and the drag-suction device, the effects that the silt dragging depth is regulated and is large, the soil breaking effect is better, partscan be conveniently and rapidly replaced when the drag heads are damaged and influences on the construction process are reduced are achieved, and the drag head device further has the beneficial effectthat silt can be efficiently sucked.

Description

technical field [0001] The invention belongs to the technical field of dredgers, in particular to a drag head device capable of adjusting the dredging depth. Background technique [0002] With the continuous improvement and enhancement of environmental protection awareness such as ecological environment protection and land resource protection in our country, trailing suction dredgers will be used in some river channel cleaning projects, and trailing suction dredgers use rake heads to break the soil and suck mud A dredger with pipe suction. However, during the use of trailing suction dredgers, it may be impossible to adjust the rake head to the required position and dredging depth, resulting in poor dredging effect of the rake head; moreover, the bottom of different rivers sometimes encounters dense compaction In the case of silt, fine sand and hard clay, the bottom of the river is hard to dig, the rake head cannot effectively break the soil, and even the rake head is greatl...
