Abstract
A scraper-chain conveyor, for use in inclined mine workings, comprises a plurality of channel sections joined together end-to-end, and a scraper assembly. Each channel section has a pair of side walls interconnected by a floor plate. The scraper assembly comprises a plurality of scrapers connected to a drive chain. The side walls of the channel sections are shaped to define, together with the floor plates, three vertically-spaced, generally trapezoidal ducts. The uppermost and lowermost ducts provide guidance for the scrapers when the scrapers are respectively in their upper and lower runs. The middle ducts accommodate coupling members, such as toggle bolts, for connecting the channel sections together.
