ABSTRACT:
A mineral mining installation employs a scraper-chain conveyor with separate channel sections each with a floor plate connected between sigma-shaped side walls arranged end-to-end and a scraper-chain assembly is circulated along the channel sections to transport material. L-shaped components are attached to the side walls of the channel sections and these components define or connect with spaced-apart supports projecting beneath the lower flanges of the side walls to produce slots therewith which receive bottom plates closing off the underside of the conveyor. Tongues on these bottom plates serve as a locating and stop means engageable with the supports. A guide for a machine and for receiving the chain used to move the machine is supported by the L-shaped components on the mineral face side and a multi-part displaceable screen is carried by the L-shaped components on the opposite side.
