ABSTRACT:
Device for the conveyance of material, in particular bulk material, comprises at least two parallel, mating trough-type conveyor elements which can move lengthwise relative to each other. Each conveyor element has an essentially U-shaped cross section. The open sides of the conveyor elements face each other, with the free edges of the side walls essentially resting against each other, so that a closed conveyance space is produced in the form of an oblong conveyor box. The two conveyor elements are provided with a cyclical drive which acts both transversely to and in the lengthwise direction of the conveyor elements, the drive of the two elements when transverse to the lengthwise direction being in phase, and in the lengthwise direction exhibiting a relative phase shift of about 180 degrees.
