Abstract
A transfer station assembly is provided for transferring mineral material from a longwall scraper-chain conveyor to a roadway scraper-chain conveyor. The transfer station includes a box frame, in which the upper run of the roadway conveyor is guided between the upper and lower runs of the longwall conveyor. Guide bars are provided for guiding the scrapers of the scraper assembly of the roadway conveyor within the box frame. The guide bars for the roadway conveyor are detachably secured to the box frame so as to be readily releasable and replaceable by other guide bars, whereby roadway conveyors of different types and/or widths can be connected to the box frame.
