Adjustable cutter dredging apparatus for reaming suction dredger

Abstract

The invention discloses an adjustable reamer dredging device for a cutter suction dredger, which is composed of a reamer leveling device, a protective cover opening and closing device, a mud cutting and conveying device, and a hydraulic drive device. The leveling device of the reamer realizes leveling under the action of the hydraulic cylinder through the hinge lever mechanism, and the profile of the reamer under different slopes is flattened with the sediment in the dredged water area; the opening and closing device of the protective cover is realized through the hinge lever mechanism under the action of the hydraulic cylinder The protective cover is opened; the reamer in the mud cutting and conveying device is a conical spiral structure, and the inner cavity is equipped with a spiral mud conveying mechanism. Under the action of the hydraulic drive device, the bottom mud is quickly cut and sent to the mud suction port. The suction pipe sucks away. The invention has the characteristics of smooth excavation bottom mud, strong adaptability to soil quality, high production efficiency, and environmental protection dredging such as preventing secondary pollution.

Description

technical field [0001] The invention relates to dredging engineering equipment technology, in particular to an adjustable cutter dredging device for a cutter suction dredger. Background technique [0002] Due to natural or man-made reasons, a lot of silt is deposited at the bottom of rivers, lakes and near seas. In order to purify water, improve the environment and dredge waterways, people usually use dredging ships to clean up the silt. At present, there are many types of dredging ships, and cutter suction dredgers composed of cutters and mud pumps have been widely used. The dredger works by relying on the self-rotation and left-right swing of the reamer installed at the front end of the reamer bridge and the suction of the dredger pump, loosening the soil at a specified depth underwater and sucking and discharging it to the designated unloading area. Due to the backward technology of traditional cutter suction dredgers, it often causes pollution in dredged waters and une...

AI Technical Summary

Problems solved by technology

Although the excavated section of this reamer is a plane at a certain depth, when the depth of the landing bridge changes, the excavated section will appear wavy, the excavation accuracy will deteriorate, and it cannot excavate hard soil.
