Abstract
A mineral mining installation has a plough guided for movement along a scraper-chain conveyor. Roof supports are connected to the conveyor with the aid of shifting mechanisms which employ boom-type guide linkages designed to co-operate with a compact controller to adjust the tilt of the conveyor and the cutting horizon of the plough. The controller employs a plate-like guide block guided for up and down motion at the goaf side of the conveyor. An hydraulic piston and cylinder unit is disposed alongside the goal side of the conveyor and pivots a cranked lever to raise or lower the guide block. The guide block is coupled to a headpiece of an associated one of the boom linkages so that the motion of the guide block is transferred to the headpiece.
Claims18
In or for a mineral mining installation comprising a conveyor, a winning machine guided for movement along the conveyor and roof supports connected to the conveyor with a boom-type guide linkages;
- an improved control arrangement for adjusting the operating position of the machine, said control arrangement at least including a guide member, means connected to the conveyor for guiding the guide member for raising and lowering motion, means for displacing the guide member relative to the guide means comprising an hydraulic piston and cylinder unit and a pivotally mounted cranked lever connected between the unit and the guide member and means coupling the guide member to a headpiece of one of the guide linkages so that displacement of the guide member is transmitted to the headpiece in a manner to cause the conveyor to adopt various angular positions.
