Description

Detachable belt conveyor cylinder cleaning device for colliery Technical Field The utility model belongs to the field of coal mine equipment, and particularly relates to a detachable belt conveyor roller cleaning device for a coal mine. Background The belt conveyor is used as core capacity equipment for coal mining and transportation operation, and the stable operation of the belt conveyor directly determines the coal production efficiency. However, the underground is in a severe environment with high humidity and high dust for a long time, so that the surfaces of the conveyor rollers and the belt are extremely easy to adhere to impurities such as coal slime, coal dust and the like. The continuous accumulation of the impurities can not only cause faults such as belt slipping and deviation, reduce the transportation efficiency, but also increase the equipment abrasion and the running resistance, thereby causing a great deal of energy consumption. Currently, manual cleaning and fixed scraper cleaning devices are commonly adopted in the coal mine industry to clean the surface of a roller. The manual cleaning is low in efficiency, potential safety hazards such as falling objects and slipping exist in the underground complex environment, and the fixed scraper cleaning device is difficult to adapt to belt conveyors with various diameter rollers and models due to fixed structures, so that the equipment needs to be replaced integrally during upgrading, and the resource waste is serious. In addition, most of the existing scrapers are fixedly installed, scraping angles cannot be flexibly adjusted according to roller abrasion conditions and belt running directions, and cleaning effects are difficult to meet the requirements of efficient production of coal mines.
