ABSTRACT:
Connection means for connecting two adjacent channel sections of a scraper-chain conveyor comprises two coupling elements fastened to the outer sides of the adjacent ends of the channel sections, and a coupling member for connecting the two coupling elements. The coupling member has a shank provided at each end with an enlarged head portion. The coupling elements are provided with laterally open recesses for receiving, with a predetermined amount of axial play, the coupling member. One of the coupling elements is provided with a projection which mates, with an all-round clearance, with a recess in the other coupling element. One head portion of the coupling member is provided with an axially extending locking member which extends behind a complementary locking member fastened to one of the channel sections. The other head portion of the coupling member is provided with at least one locking projection which co-operates with a corresponding locking recess in the adjacent coupling element.
