Abstract

A mineral mining machine guide is composed of individual sections joined end-to-end alongside the pans of a scraper-chain conveyor. Each guide section has a side wall component and a web plate component with spacers therebetween dividing upper and lower chain guide passages. An inclined foot plate component projects beneath the web plate component which is itself spaced above the foot plate component to form a slot through which the machine engages with the chain run in the lower passage. A pivotable cover closes the upper passage. Toggle-like coupling pieces fit into pockets in the ends of the web plate components of adjacent sections. Compartments in the web plate components above the pockets and at the level of the upper passage receive extensions of the covers which are hinged in these compartments. The coupling pieces are held in place with detachable locking plates which additionally co-operate with the covers to limit their outward pivotal movement.
