Self-dedusting intelligent coal mining machine

Abstract

The invention relates to a self-dedusting intelligent coal mining machine, and belongs to the technical field of coal mining machines. The self-dedusting intelligent coal mining machine specifically comprises a rocker arm of the coal mining machine and a spraying device which is fixed on the rocker arm. The spraying device comprises a mounting tube, movable atomizing nozzles which are mounted around the mounting tube and can freely adjust the angle, and a fixed atomizing nozzle which is fixed on the mounting tube. The movable atomizing nozzles and the fixed atomizing nozzle are connected to awater distribution pipe, which is connected to a water supply pipe of the coal mining machine. The movable atomizing nozzles are used for synchronous control with the coal mining machine; the movableatomizing nozzles are used for spraying in the direction of a coal cutting roller; and the fixed atomizing nozzle is used for spraying on a scraper conveyer. The self-dedusting intelligent coal miningmachine of the invention is simple to operation and convenient to control. By the automatic control, the dedusting effect is better.

Description

technical field [0001] The invention relates to a self-dust-cleaning intelligent coal shearer, which belongs to the technical field of coal shearers. Background technique [0002] The working environment in the underground stope of the coal mine is extremely bad. When cutting coal, the coal dust concentration can reach 26.6mg / m3, and the total dust is 572.6mg / m3. , a great threat to the safety of coal mine production and the health of workers, so dust removal devices must be used in the coal mining process, and the coal shearers used in coal mines are all drum shearers, and the dust removal method used in the coal mining process is mainly water sprinkling For dust reduction, the coal shearer is equipped with two types of water sprinkling: internal spray and external spray. The external spray is mainly on the top of the rocker arm and adopts a fixed structure, which cannot be automatically adjusted according to the actual situation. It can only be sprayed at a fixed angle to ...

The external spray is mainly on the top of the rocker arm and adopts a fixed structure, which cannot be automatically adjusted according to the actual situation. It can only be sprayed at a fixed angle to remove dust. Small, poor dust removal effect, and fixed on the top of the rocker arm of the coal mining machine, it is easy to be damaged by falling coal
