Abstract: A conveyor comprising a pair of conveyor units each comprising a frame supporting a roller at each end over which a conveyor belt passes as a continuous loop in a channel defined by side walls of the frame, characterised in that the frames (3) of the two conveyor units (1,2) are connected together with respective runs of the conveyor belts (5) opposed face-to-face so that they and the respective side walls (6) along both sides define an enclosed conveying channel (8), at least one roller (4) of the frames (3) being driven by a motor (10) so that the opposed runs of the conveyor belts (5) move in the same direction to convey material therebetween, and a plurality of projections (15) are provided across the surfaces of the conveyor belts (5) so as to engage and support material vertically within the conveying channel (9).

Abstract: The invention is directed to a conveying system comprising a plurality of portable conveyor units which may be arranged serially to form a conveyor feed path. Each conveyor unit includes a plurality of rollers, one of which is associated with an electric motor for supplying power to the conveyor, and a pair of quick-release electrical connectors. One of the electrical connectors is designed to receive an electrical cable from a preceding conveyor while the other electrical connector is designed to have an electrical cable extending between it and an electrical connector on a succeeding conveyor. The electrical connectors supply power to the electric motor. Depending on which electrical connector of the pair of electrical connectors serves as the inlet to electrical current, the direction of conveyor may be reversed.
