Abstract
The utility model discloses a coal scraper for a belt conveyer, which is invented for solving the problems of higher labor intensity, lower coal scraping efficiency and the like in the prior art. The coal scraper for the belt conveyer comprises a rotating shaft, a supporting plate and a scraping plate, wherein two ends of the rotating shaft are used for rotating the guiding chute connected with the head of the belt conveyer, the bottom of the supporting plate is connected with the rotating shaft, and the scraping plate is arranged at the top of the supporting plate. The rotating shaft at two ends of the supporting plate is connected with one end of a sinker weight arm, a sinker weight is arranged at the other end of the sinker weight arm; and the included angle between the sinker weight arm and the supporting plate is an acute angle. In the structure of the coal scraper for the belt conveyer, the supporting plate, the scraping plate, the rotating shaft and the sinker weight arm form a lever, the lever takes the two rotary connecting ends of the rotating shaft as the fulcrums and is arranged above an unloading rotary drum of the head of the belt conveyer. By utilizing the sinker weight at the end of the sinker weight arm, the scraping plate can firmly stick to the belt surface when the scraping plate bears the load of the coal granules on the belt surface, neatly scraps the coal into the guiding chute, lowers manual work, improves the coal scraping efficiency and reduces safety accidents.
