Abstract
A conveyor pan connection of a scraper chain conveyor which conveyor pans having side profiles having profiled strips which form guide channels for scrapers and having outwardly directed flange strips. The conveyor pan connection includes coupling plates which are welded in between the outwardly directed flange strips at the ends of the side profiles of the conveyor pans, a first coupling plate projecting from an end of a first conveyor pan over a joint between conveyor pans and a second coupling plate at the opposing end of a second conveyor pan is set back with respect to the joint. Each coupling plate is comprised of a plate portion, an outwardly projecting coupling pin with a convexly rounded rear face, an outwardly projecting retaining lug on the same face and toward the end of the coupling plate distal to the joint, and one or more integral ribs on the rear side of the plate, such that when the coupling plate is in position on the side profile, the plate portion is concealed between the outwardly directed flange strips.
