Abstract

To firmly connect an upper trough-like component of a scraper-chain conveyor to a lower component use is made of arch-like locking pieces which fit on a side plate of the lower component which overlaps the side wall of the upper component. The upper regions of the locking pieces having inwardly projecting noses which fit into apertures in the side plate and side wall. Sockets are formed in projections on the side plate to receive the heads of screw-threaded securing elements which locate in recesses in the locking pieces and project through holes in side walls thereof. The securing elements adopt an inclined disposition and when nuts are tightened on their shanks the locking pieces tend to force and hold the upper component down on the lower component.
