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.
A conveyor trough construction, particularly for scraper chain conveyors, comprising a conveyor having longitudinal sidewalls formed of a plurality of abutting sections each having a longitudinally extending bore therethrough defined by interior walls having conical portions at each end tapering toward the adjacent end, a bolt extending through the bores of adjacent section pairs and having a conical portion at each end tapering toward the adjacent end and complementary to the conical wall portions defining the bores, each section having a side wall opening which extends into said bore, and a locking spring inserted in the side wall portion and engaged over said coupling bolt, the interior walls of said bore being dimensioned in the vicinity of said locking spring to provide an axial clearance for said locking spring.
