Improved dust-proof cover belt system for warehouse

The utility model relates to an improved dust-proof cover belt system for a distribution bin, which is mainly used for a reversible belt conveyor for the distribution bin, and uses a flexible rubber belt to cover the reversible belt conveyor for the distribution bin and a coal bin which move in a reciprocating manner so as to block coal dust. And the reinforcing ribs are fixed on the rubber belt, so that the phenomena of drooping, bending and bulging under the action of gravity are avoided, and the rubber belt can tightly cover the reversible belt conveyor and a coal bunker inlet to prevent coal dust from escaping. The planetary roller is mainly composed of four rolling shafts and a main shaft, and the four rolling shafts can revolve around the main shaft and can independently rotate. When the reversible belt conveyor with the bunker unloads materials to different coal bunkers in a reciprocating mode, the reinforcing ribs meet the planet rollers along with movement of the rubber belt, the rolling shafts on th
