[0002] By burning coal, we can obtain important energy such as electricity and heat. During loading or short-distance transmission, coal needs to be transported through conveyor belts. The existing conveyor belts can basically meet daily use needs, but there are still some shortcomings that need to be improved.

[0003] When conveyor belts widely used on the market are transporting coal, a large amount of coal residue will adhere to their surface. If the coal adsorbed on the surface of the conveyor belt is not cleaned in time, the coal residue will easily compact other coal and be tightly adsorbed on the surface of the conveyor belt, increasing the difficulty of subsequent cleaning. For this reason, we propose a scraper cleaning device for conveyor belts to solve the above problem. Summary of the invention
