Abstract
A belt conveyor comprises an elongate tube with an upper run of the belt passing through the tube from a hopper at a lower exposed feed portion of the belt. The feeding of the material from the hopper onto the belt and into the tube is enhanced by the addition of a tapered auger flight on a shaft extending longitudinally of the belt from the bearing at the rear wall of the hopper to a hanger bearing within the tube, The auger flight assists in transporting the material through the open mouth of the tube and spreading the material over the surface of the belt.
Claims8
A conveyor comprising:
- an elongate tube having a feed end;
- an endless belt;
- guide means mounting the belt such that a feed run of the belt passes through the tube for carrying particulate material therethrough and a return run passes outside the tube with a feed end portion of the belt exposed beyond the feed end of the tube;
- a hopper at the feed end of the tube for directing particulate material deposited into the hopper such that the particulate material is guided onto the feed end portion of the belt and is moved thereon longitudinally of the tube into the feed end of the tube;
- and an auger feed member mounted above the feed end of the belt and extending longitudinally therealong with a forward end of the auger feed member projecting into the feed end of the tube for assisting the feed of the particulate material into the feed end of the tube.
The conveyor according to claim 4 wherein the flight gradually tapers from the remote end to the inside end.
