Buried pipeline dredger

Abstract

The invention discloses a buried pipeline dredger. The buried pipeline dredger comprises a crushing structure, wherein a driving source structure is arranged on one side of the crushing structure, a first driving structure is fixedly installed on the side, away from the crushing structure, of the driving source structure, and a guiding structure is fixedly connected to the side, away from the driving source structure, of the first driving structure. According to the buried pipeline dredger, a first driving motor drives a rotating plate to rotate through a worm and worm gear transmission part, then a drill bit is driven to rotate, the drill bit can crush obstacles inside a pipeline while rotating so as to prevent the obstacles from influencing normal conveying of the pipeline, and meanwhile, a circular ring plate can drive a grinding block to rotate while rotating, and the friction end surface of the grinding block makes contact with the inner wall of the pipeline so that the grinding block can rub the interior of the pipeline, objects adhering to the inner wall of the pipeline are further ground and removed, and the effect of removing the obstacles inside the pipeline is improved.

Description

technical field [0001] The invention relates to the field of buried pipelines, in particular to a dredger for buried pipelines. Background technique [0002] A pipeline is a device used to transport gas, liquid or fluid with solid particles connected by pipes, pipe connectors and valves. Usually, after the fluid is pressurized by blowers, compressors, pumps and boilers, it flows from the high-pressure part of the pipeline to the low-pressure part, and it can also be transported by the pressure or gravity of the fluid itself. Pipes are widely used, mainly in water supply, drainage, heat supply, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices. Some pipelines need to be buried under the ground, which are often called buried pipelines. [0003] This application improves the existing technology. In the existing construction process, the buried pipeline is easy to enter the concrete du...

AI Technical Summary

Problems solved by technology

[0003] This application improves the existing technology. In the existing construction process, the buried pipeline is easy to enter the concrete due to insufficient protection or malicious damage, and materials such as sand and gravel can easily cause pipeline blockage. Therefore, a buried pipeline is proposed. The dredger, the main function of the dredger is to clean up the blocked substances in the pipeline through the pipeline without damaging the ground, and dredge the pipeline.
