IMPRVEMENTS IN SCRAPER-CHAIN CONVEYORS IMPROVEMENTS IN SCRAPER-CHAIN CONVEYORS

摘要

A scraper-chain conveyor channel section or pan has side walls interconnected by a floor plate. The underside of the pan along which the lower run of a scraper-chain assembly runs is covered over by a bottom plate which is easily detached. To fasten the bottom plate in position use is made of one or more shaped lateral regions on the bottom plate which engage in an open pocket formed inside a guide provided on the mineral face side wall of the pan. The shaped region or regions and the pocket permit the bottom plate to be swung away from the undersurface of the pan at an angle to permit withdrawal from the pocket. Releasable tension springs hold the bottom plate against the undersurface of the pan.
