摘要： A mineral mining installation employs a scraper-chain conveyor constructed from individual pans joined end-to-end and a plough having a drive plate running beneath the conveyor and on a skid bed formed as a sub-frame structure on the floor of the working. The drive plate is connected via guide means to the haulage run of a chain in a lower guide passage at the side of the conveyor opposite to the plough. An upper guide passage accommodates the return run of the chain. The passages are defined by a guide structure fitted to the side walls of the pans and includes detachable covers which can be removed for access purposes. At least some of the covers are linked with the sub-frame structure with the aid of tongue-and-groove connections. These connections permit limited movement of the pans and guide structure relative to the sub-frame structure longitudinally of the conveyor and limited raising and tilting movements of the side walls of the pans opposite the machine and the covers relative to the sub-frame structure as the drive plate passes along the conveyor.

摘要： Apparatus for controlling the position of a mineral winning machine, such as a plough, movable along a guide at the mineral face side of a scraper-chain conveyor employs a connector bracket at the goaf side of the conveyor to which a floor-engaging skid plate is pivotably linked. A beam extends from a roof support and is also pivotably connected to the skid plate remote from the conveyor. A pair of piston and cylinder units are pivotably connected at their upper ends to the bracket. One of the units is pivotably connected to the skid plate and the other is pivotably connected to the beam. By operating the units together the skid plate can be held against the floor over part or all of its lower face while the conveyor goaf side is raised or lowered accordingly.

摘要： A mineral mining installation comprises a longwall scraper-chain conveyor, and a mineral winning plough. The plough is drivable to and fro along the face side of the conveyor by means of a plough drive chain and a three-part sword plate. The plough drive chain is housed in a chain guide attached to the goaf side of the conveyor. The sword plate is attached to the plough, and passes underneath the conveyor. Each pair of adjacent sword plate parts is detachable joined together by a pair of detachable pivot joints positioned respectively adjacent to the face and goaf sides of the conveyor.

摘要： A mineral winning plough, such as a coal plough, has a plough body adapted to be moved to and fro alongside a mineral face on a plough guide. The plough body is provided with a pair of vertically-adjustable carriers, each of which is provided with floor cutters. The plough body is provided with setting means for raising and lowering the carriers into rest and working positions respectively. The setting means comprises a slide plate, and an intermediate member. The slide plate is mounted in an aperture in the plough body for limited movement relative thereto. The slide plate is attachable to a plough drive chain. The intermediate member forms a mechanical operative connection between the slide plate and the two carriers. The intermediate member is rotatably mounted on the plough body, and is positioned between the two carriers. The arrangement is such that movement of the slide plate relative to the plough body in a given direction forces one of the carriers to be lowered into its working position, and causes the other carrier to be raised into its rest position.
