A long service life roller coal mining device with dust suction function

Abstract

The invention relates to a roller coal mining device with a dust collection function and long service life. The roller coal mining device comprises a first motor, a roller, a processor and a processing mechanism. the processing mechanism comprises an air inlet pipe, a processing pipe, an air outlet pipe, a recovery assembly, a purification assembly and a cooling assembly; the purification assemblycomprises a filter screen, a fan, a dredging block, a reciprocating unit and an opening; the cooling assembly comprises a water tank, a water pump, a water injection pipe, a water conveying pipe, multiple nozzles and multiple cooling units. The roller coal mining device with the dust collection function and the long service life has the advantages that the dust collection function is fulfilled, external air is sucked into the processing pipe through the air inlet pipe, coal dust is filtered by the purification assembly, coal dust is recovered in a centralized mode through the recovery assembly, air at the bottom of the processing pipe is cooled through the cooling assembly and sprayed out of the air outlet pipe, when the air enters the air inlet pipe and is sprayed out of the air outlet pipe, heat of cutting teeth is absorbed, the cutting teeth are secondarily cooled, the service life of the cutting teeth is prolonged, the coal dust is recovered in a centralized mode through the recovery assembly, and therefore the practicability of the equipment is improved.

Description

technical field [0001] The invention relates to the field of coal mining equipment, in particular to a drum coal mining device with a dust suction function and a long service life. 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] In recent years, with the increase of coal mine mining, the performance of coal mining devices has been perfected day by day, and the power of coal shearers has been continuously increased. In order to adapt to the current high-efficiency mining, the requirements for coal shearer drums have also been continuously improved. However, during the operation of the existing coal shearer drum, the pick rotates w...

Problems solved by technology

However, during the operation of the existing coal shearer drum, the pick rotates with the drum, and friction occurs continuously with the coal body on the coal wall, resulting in a sharp increase in the temperature of the pick and shortening the service life of the pick. Not only that, but in the process of coal mining, when the pick cuts the coal body on the coal wall, it is easy to produce some fine coal particles or even coal dust, which affects the air quality of the working environment, and these There are also coal mine resources in the coal particles, allowing these small coal particles to float in the air also causes a waste of resources, thereby reducing the practicability of the existing shearer drum
