ABSTRACT:
A guide for a mineral winning or loading machine, such as a coal plough, is composed of assemblies secured to the mineral face side of a conveyor. The assemblies have angle plates with upstanding wall portions securable to the side walls of the conveyor and integral foot portions supporting the machine and resting on the floor of the mine working. Spacers separating upper and lower passages for guiding a drive chain are in turn secured to the wall portions of the angle plates and these passages are shielded by cover plates formed with ramp-like inclined guide surfaces for the machine. The cover plates are pivoted to the spacers at their lower regions so that they can be pivoted outwards to allow access to the passages therebehind. The cover plates are locked with releasable devices to the wall portions in their closed position and have recesses accommodating the spacers which have inclined surfaces forming continuations of the guide surfaces of the cover plates.
