Conveyor chute with closable bottom aperture for chain scraper conveyors, in particular for use in mining

摘要

A conveyor chute for chain scraper conveyors, in particular stope conveyors, having a bottom aperture provided in the conveyor bottom forming an inspection or repair aperture and closed by way of a closure panel during the conveying operation. The closure panel is guided in slot-shaped apertures of the two side profiles of the conveyor chute by way of their opposite panel edges and secured against displacement by a locking device. The two side profiles of the conveyor chute are each formed of two profile strips in superimposed array which are not interconnected to the conveyor bottom in the region of the bottom aperture. The two side profiles form the slot-shaped apertures in which the locking of the closure panel in the closed position takes place only on one of the two side profiles.
