The invention discloses a belt working face adhesive material three-dimensional cleaning device. The belt working face adhesive material three-dimensional cleaning device comprises a machine frame, two unpowered carrier rollers, a cleaning belt, a vibrating device and a material return plate. The machine frame is fixedly installed on a machine frame of a belt conveyor, and the two unpowered carrier rollers are installed on the machine frame. The cleaning belt surrounds the two unpowered carrier rollers in a connection mode, is located below a belt in the belt conveyor and is attached to the working surface of the belt of the belt conveyor. The vibrating device is installed on the machine frame, makes contact with the non-working surface of the belt and is located above the cleaning belt. The material return plate is installed on the machine frame in an inclined mode and located below the cleaning belt. Due to the facts that the cleaning belt conducts multi-angle and repeated scraping movement on remaining materials on the working face of the belt, and the up-and-down vibration effect of the vibrating device is achieved, the remaining materials can be separated from the working faceof the belt, the effect of three-dimensional omni-directional material cleaning is achieved, and the belt working face adhesive material three-dimensional cleaning device can have the advantage of being good in cleaning effect.
