摘要:
A device for clearing residues of pulverulent or particulate product from a belt conveyor includes a vibrating roller freely rotatably mounted between an upper carrier run and a lower return run of said conveyor belt and biased into engagement with the inner side of the return run, the vibrating roller being sealed against ingress of dust and other foreign matter and enclosing a vibration generator motor. In such a device the vibration generator motor is protected from the effects of dust and climatic variations and is of compact form. The vibrating roller is resiliently supported by coil springs which thrust the roller against the inside face of the return run of the conveyor belt to ensure that contact is maintained between the vibrating roller and the return run of the conveyor belt even when the conveyor belt is circulating at a high linear speed.
