[0002] A conveyor belt, also known as a transport belt, is a composite product of rubber, fiber, or metal, or a composite product of plastic and fabric, used in belt conveyors to carry and transport materials. It is widely used in industries such as cement, coking, metallurgy, chemicals, and steel where conveying distances are short and volumes are small. Conveyor belts enable continuous, efficient, and high-angle transport. When transporting materials with a high water content, a large amount of material often adheres to the conveyor belt, necessitating a cleaning mechanism to clean the conveyor belt. The prior art discloses a roller brush conveyor belt cleaning structure with authorization publication number CN207361230U, comprising a main brush assembly including a cylindrical roller brush.
