摘要： A plough guide is composed of sections built onto the runs of channelling of a scraper chain conveyor. Behind a covering comprising covering hoods pivotable on joints, there are chain guide channels for the plough chain separated by spacers. Underneath each covering hood there is a robust guide beam which forms part of a lower guide for the plough. Each guide beam of solid rolled section is provided at each of its two ends with a recess into which is welded a stout bearing plate which on a level with the spacers. The bearing plates are equipped with open journal bearings for hinge pins positioned at the foot of the covering hood. The hinge pins are integral with hinge pieces, which are welded into recesses at the two ends of the covering hood.

摘要： Disclosed is a plough mining installation for the underground working of minerals, preferably those occuring in thin seams, which incorporates plough bodies interlinked by rigid rods into a ploughing system reciprocating along the face due to a reciprocatory means consisting of an immovable hydraulic ram and a plurality of movable hydraulic rams. Spaced apart along a frame of the installation, the movable hydraulic rams are linked to each other by articulated joints resting on slides arranged to travel on longitudinal guide means. Thus, the ploughing systems is capable of reciprocating through a distance equalling the length of the aggragate stroke of all the hydraulic rams.

摘要： A mineral winning installation employs a plurality of plough bodies spaced apart along the mineral face and interconnected to form a common plough train which is moved in unison back and forth along the face. The plough bodies have high-pressure fluid emission nozzles and a high-pressure pipe line extending between the bodies supplies high pressure fluid to the nozzles, which discharge the fluid for impact with the mineral face.
