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.
An endless belt conveyor comprising frame means, conveyor belt means, first and second guide roller means carried by said frame means and supporting said conveyor belt means to have an upper carrier run and a lower return run thereof, vibrating freely rotating roller means in contact with the inside face of said conveyor belt means on said return run thereof, supporting roller means engaging said return run of said conveyor belt means and located such that said vibrating roller means is disposed between said supporting roller means and said first guide roller means, first and second bearer means supporting said vibrating roller means at respective ends thereof, means resiliently connecting said first and second bearer means to said frame means, vibration generator motor means disposed within said vibrating roller means and having a stator connected to said first and second bearer means, and means sealing said vibrating roller means against access of dirt to said vibration generator motor means, wherein said first and second bearer means each comprise a bearing having an inner race and an outer race, wherein said stator means of said vibration generator motor means includes first and second cylindrical journal pins engaged in the respective bearings of said first and second bearer means, and wherein said first and second bearer means each further include (a) respective end cover means and means for connecting said end cover means to the respective one of said first and second journal pins and (b) respective abutment means carried by said vibrating roller means for preventing axially inward movement of said bearing with respect to said vibrating roller means by engaging the outer race of said bearing.
An endless belt conveyor comprising frame means, conveyor belt means, first and second guide roller means carried by said frame means and supporting said conveyor belt means to have an upper carrier run and a lower return run thereof, vibrating freely rotating roller means in contact with the inside face of said conveyor belt means on said return run thereof, supporting roller means engaging said return run of said conveyor belt means and located such that said vibrating roller means is disposed between said supporting roller means and said first guide roller means, first and second bearer means supporting said vibrating roller means at respective ends thereof, means resiliently connecting said first and second bearer means to said frame means, vibration generator motor means disposed within said vibrating roller means and having a stator connected to said first and second bearer means, and means sealing said vibrating roller means against access of dirt to said vibration generator motor means, wherein said bearer means further comprise:
An endless belt conveyor comprising a conveyor frame;
