A safe and reliable coal shearer roller for coal mining

Abstract

The invention relates to a safe and reliable drum for a coal mining machine for coal mining. The safe and reliable drum comprises an electric motor, a processor, a cylinder body, an outer shell, a dust removing mechanism, a recycling mechanism and a plurality of cutting picks; the dust removing mechanism comprises a water tank, a water injection pipe, a water pump, a water duct, a connecting pipe,a rotating component and a plurality of dust removing components, wherein each of the dust removing components comprises a spray nozzle and a spray pipe; and the recycling mechanism comprises a recycling pipe, a recycling box, a fixing component, an inclined pipe, a filter screen and a recycling component, wherein the recycling component comprises a bracket, a guiding wheel, a conveyor belt, a first motor, a driving wheel and a plurality of scraper blades. According to the safe and reliable drum for the coal mining machine for coal mining, water flow is sprayed through the dust removing mechanism, and coal dust generated during coal mining is adsorbed to ensure construction safety; and not only that, the recycling mechanism is used for recycling the sprayed water flow to facilitate cyclicutilization of water resources, and the coal dust is collected in the recycling box through the recycling component, so that the utilization of coal dust resources is facilitated, and the practicability of the safe and reliable drum is further improved.

Description

technical field [0001] The invention relates to the field of coal mining equipment, in particular to a safe and reliable coal shearer drum used for coal mining. Background technique [0002] Drum shearer is a coal mining machine that uses the spiral drum as the working mechanism and realizes coal falling by the principle of hobbing. When the drum rotates at a certain speed and the shearer runs at a certain traction speed, the drum rotates and cuts into the coal wall. Under the action, it is pushed into the scraper conveyor on the working face. [0003] During the coal mining process of the existing drum shearer, the picks rotate with the drum on the coal wall, which will generate a large amount of coal dust, and the coal dust will fly in the air, which will not only affect the breathing monitoring of the underground workers, but also when the underground When the coal dust flying in the air reaches a certain concentration, a violent explosion will occur, which will cause s...
