Abstract

The invention discloses a novel hob-assisted rake suction dredger head, which includes a head cover, a reduction box, coupling one, coupling two, an underwater motor, a rotating shaft, and a hob and rake teeth; the reduction box, coupling one, coupling two, and underwater motor are located on the side of the rake head cover, the rotating shaft, hob and rake teeth are located in the rake head cover, and the underwater The output shaft of the motor is connected with the input shaft of the reduction box through the first coupling, and the output shaft of the reduction box is connected with the rotating shaft through the second coupling. The rotating shaft drives the hob to rotate and cut. The front end of the head, and the hob is located at the rear end of the tines. The invention adopts a novel hob to assist the rake head in rock breaking, which makes up for the insufficient rock breaking ability of the traditional rake head, improves the rock cutting efficiency of the rake suction dredger, and increases the application range of the rake suction dredger.

Description

technical field [0001] The invention relates to a novel hob-assisted drag suction dredger head, which belongs to the technical field of dredging engineering. Background technique [0002] With the rapid development of my country's shipping industry and the vigorous development of infrastructure projects such as ports and waterways, the domestic demand for dredging ships is increasing. Trailing suction dredger is the most commonly used dredging ship in dredging projects. It has strong wind and wave resistance, little interference to shipping, large dredging depth, and unlimited transportation distance. It is suitable for land reclamation and large ports for deep water and long-distance operations. Waterway construction and maintenance projects. With the gradual widening and deepening of port channels at home and abroad, dredging projects for hard clay, cemented sand and even rocky substrates are increasing. For rocks and soils with a uniaxial saturated compressive strength g...
