Title:
HARBOR CHANNEL DREDGING EQUIPMENT, AND METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/196244
Kind Code:
A1
Abstract:
The present invention relates to the technical field of sediment removal equipment. Against the problem that mobile dredging cannot be implemented because existing dredging equipment cannot be mounted on a small ship due to large size, the following solution is provided now, comprising a base. A supporting post is rotatably mounted on the top of the base; a rotary plate is fixedly sleeved on the supporting post; a top rod is fixedly mounted on the top of the supporting post; a motor is fixedly mounted on the top of the top rod; a first through hole is formed on the top rod; a fixing tube is fixedly mounted in the first through hole; the inner wall of the fixing tube is provided with a thread groove. In the present invention, the motor controls a height-adjustable post to move up or down, so as to control excavation buckets to move up or down; an air pump controls the opening and closing of the excavation buckets, so that sediment can be excavated by a simple structure; the cooperation of balls and fixing pads make the rotation and fixing of the supporting post more convenient and labor-saving; thus, the entire equipment can be adapted to be mounted on a small ship for use.
