摘要： A plough drive employs a plough box mounted face to face on a side plate or intermediate plate of a machine frame of a scraper-chain conveyor. A rotatable chain wheel is disposed in the box for driving a chain coupled to the plough. A chain stripper seats in a pocket in the box and is locked therein. The stripper can be withdrawn laterally from the pocket. The stripper is connected to an adjustable annular collar on the casing of a gearing unit which drives the chain wheel and is detachably secured to the side of the box remote from the frame. The gearing unit and stripper can thus be withdrawn together laterally from the box and the chain wheel can likewise be withdrawn laterally via an aperture in the side of the box remote from the frame.
