Dustproof cover with self-cleaning function

The utility model belongs to the technical field of coal mine underground coal gangue separation, and particularly relates to a dust cover with a self-cleaning function. The LED lamp comprises a columnar light-transmitting body allowing light to penetrate through and a protective shell coaxially arranged on the outer cylindrical surface of the light-transmitting body in a sleeving mode. A light-transmitting hole used for avoiding a light path is formed in the protective shell in a radial penetrating mode. The protective shell and/or the light-transmitting body are/is driven by a power assembly, so that the protective shell and the light-transmitting body can generate relative coaxial rotation action; a cleaning brush used for wiping dirt on the light-transmitting body is arranged at the position, beside the light-transmitting hole, of the protective shell, the brush face of the cleaning brush abuts against the outer wall of the light-transmitting body, and the sweeping path of the cleaning brush intersects wi
