Abstract
A channel section for a scraper-chain conveyor has a lower trough-shaped part and an upper trough-shaped part detachably fixed thereto. The lower part is made of heavy-duty metal plate and supports a plough guide section. The upper part is made of light, rolled metal sections and is easily replaceable. The lower part has a pair of side walls welded to a base plate. The base plate has an extension which projects outwardly of the face-side side wall and toward the face being won. The extension constitutes a guide rail along which the plough can slide. A ramped cover plate is pivotally attached to the free end of one arm of an L-shaped plate. The other arm of the L-shaped plate is welded to the face-side side wall so that the plate overlies the guide rail. The guide rail constitutes the plough guide section together with the cover plate and its support plate.
