Kohlenhobel,der den Foerderer mit einer Schwertplatte untergreift

摘要

A mineral mining installation composed of a mineral winning machine such as a plough guided for movement along a conveyor. The plough has a sword plate extending beneath the conveyor and guided at the side of the conveyor remote from the machine. This guidance is provided by guide members attached to the sword plate and secured to a drive chain used for moving the plough. Guard plates are attached to the side of the conveyor remote from the machine and U-shaped cover plates are in turn affixed to the guard plates with the aid of screws and spacers. The guide members and drive chain run in a guide channel defined between the guard plates and cover plates and beneath the spacers. Each guide member is elongate and has a transversely-extending recess in its upper face. A roller or wear resistant insert is accommodated in the recess and seats on a spigot therein. Wear-resistant pads are also attached to the guide members. As the sword plate tilts the periphery of the roller or a wear-resistant pad attached to the inner face of the insert is allowed to engage on the guard plates.
