Description

Lower belt cleaning and blanking recovery equipment Technical Field The utility model relates to the field of coal drop recovery, in particular to a lower belt cleaning and blanking recovery device. Background The underground coal stone conveying mainly depends on a belt conveyor, in the conveying process, due to the fact that underground environment is moist, coal slime, coal dust and small coal blocks are attached to a belt, belt load is heavy, belt deviation and the like are bad for conveying safety, belt cleaning is carried out only through a belt scraper, material waste is caused, particularly the scraper part is often arranged at a switching position, and the scraped coal dust and coal falling can locally cause coal accumulation. There is currently no corresponding solution to this problem. Disclosure of utility model The utility model aims to overcome the defects of the prior art and provide a lower belt cleaning and blanking recovery device which integrates the functions of belt cleaning and blanking recovery and uploading, avoids partial coal accumulation and fully recovers blanking. The equipment comprises a bracket, a belt scraping plate system and a coal falling recovery system; The support is an assembly base piece of the equipment and is used for being assembled below the belt conveyor when in use; The bracket is provided with a belt scraping plate system and a coal falling recovery system; the belt scraping plate system comprises a trough, and a leakage port is formed in the bottom of the trough; A belt scraper is arranged in the trough, and a height adjusting mechanism is arranged between the belt scraper and the trough or the bracket; The height adjusting mechanism is used for adjusting the height of the belt scraper to enable the belt scraper to be attached to the lower surface of the lower belt; The coal dropping recovery system is arranged below the trough and transmits the coal dropping in the trough back to the upper surface of the upper belt of the belt conveyor. The utility model has the beneficial effects that the problem of unreasonable configuration of the belt scraping plate and the problem of blanking and uploading of scraped coal dust and coal dust in the prior art are solved, the configuration structure is reasonable, the utility model is especially based on the integrated assembly of equipment, the height adjusting mechanism can respectively adjust the two scraping plates to scrape the belt, and the falling coal and the coal dust are uploaded again in cooperation with the linkage of the falling coal recycling system, so that the material waste is avoided.
