Dust removal mechanism and belt conveyor

The utility model relates to the technical field of conveyor belts, in particular to a dust removal mechanism and a belt conveyor, which comprise a conveying component, a support frame, a driving roller arranged on the support frame, and a fixed gear arranged at one end of the driving roller. In the conveying process, large chippings in the dust are blocked in a dust collection barrel through a filter screen in a rotating assembly, the dust is conveyed into the dust collector, in the conveying process of the dust, transmission blades rotate, rotating blades drive rotating brushes to rotate, and the dust is conveyed into the dust collector. Chippings on the outer side of the filter screen are scraped into the dust collection barrel through the rotating brush, the chippings fall to the top of the rotating plate, when many chippings are accumulated on the top of the rotating plate, the rotating plate rotates reversely, the chippings fall to the bottommost part in the dust collection barrel, the rotating plate ca
