ABSTRACT:
A scraper conveyor has a conveyor trough composed of at least two longitudinally adjacent trough sections having respective side walls and juxtaposed terminal faces. A pair of first connecting members is welded to the side walls of one of the sections and recessed longitudinally thereof from the terminal face of the one section. These first connecting members have convex first end faces directed towards the terminal face of the one section, and exposed outer surfaces. A pair of second connecting members is welded to the side walls of the other of the sections and each of these has an end portion projecting beyond the terminal face of the other section. The end portions have second end faces which are each formed with a concave recess in which one of the convex end faces is received, and also exposed outer surfaces. Substantially keyhole-shaped recesses are formed in the exposed outer surfaces and each of these has a narrow portion provided with an open end located at the respective end face, and with a wider portion spaced from the respective end face. Coupling elements are received in the keyhole-shaped recesses and each of these has two enlarged end sections received in the respective wider portions, and a narrower section received in the narrow portions of the cooperating recesses. With this construction the thus connected trough sections have limited freedom of relative angular displacement in vertical and in horizontal direction.
