Abstract
A drive station or machine frame assembly for a scraper-chain conveyor has a convertible frame with side walls between which a drive drum for the associated scraper-chain assembly is mounted. The frame has first and second plates arranged one above the other and extending between the side walls. The uppermost plate is detachable whereas the lowermost plate is fixed. Both plates are inclined and can form part of an ascending conveying surface prolonged by using one or more channel structure with side walls and a floor plate aligned with the plate of the frame which is used. The uppermost plate is used with a larger-size drive drum and can be removed to expose the lowermost plate for use with a smaller-size drive drum. Known forms of tongue or guide plates and chain deflectors can be mounted to the frame.
