ABSTRACT:
A conveyor trough construction, particularly for scraper chain conveyors, comprises a conveyor having longitudinal side walls formed with a plurality of abutting sections, each having a longitudinally extending bore therethrough which aligns with the next adjacent section. The bores of adjacent pairs of sections terminate in inwardly bevelled ends, and a coupling bolt extends through the bores of adjacent sections and terminates at each of its ends with an inwardly tapered portion which is engaged in the inwardly tapered ends of the bores. Each section is provided with a side wall opening, which extends into the bore, and a locking spring is inserted in the opening and engaged over the coupling bolt. The bore of the sections is dimensioned to provide an axial clearance for the locking spring.
