Abstract

The pans of a scraper-chain conveyor have a plough guide at one side. The pans are connected together at said one side with the aid of coupling pieces engaged in pockets in the side walls of the pans. Each coupling piece is pivotably fitted to a plate-like securing element which serves as a handle to enable the coupling piece to be inserted into or removed from the pockets. The securing element can be swung down into further pockets formed in the plough guide to lock the coupling piece in place.
