摘要： A coupling device for connecting a mineral mining machine, such as a plough, to a drive chain. The coupling device is intended to locate within a channel inside a slotted guide containing the drive chain. The device is composed of coaxial tubular members secured together axially. The inner tubular member supports a swivel-mounted shackle connecting with the chain and a rigidly-mounted shackle connecting with the machine. One or both tubular members are shaped or relieved at the end nearest the swivel shackle to provide a cleaning nose which forces dust or the like from the channel as the chain draws the machine along the guide. A lateral projection on the outer tubular member engages in the slot and co-operates with the nose to guide the material away through the slot.

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 coal plough has an elongate plough body which is provided with cutters at each end. The plough body is supported at each of its two ends, by a flat narrow skid on a plate of a plough guide. The skids constitute wear-resistant members and are connected to the plough body in a readily replaceable manner. The skids are so shaped that they guide the plough in the lower zone of the plough guide, and establish connection between the plough and the plough drive chain.

摘要： A cutter-bit assembly employs an arcuate wedge to secure a cutter-bit within a pocket of a holder. The wedge fits into a tapered gap between complementary curved surfaces of the holder and the cutter-bit shank. A projecting insert carried by the shank mates with a serrated portion on the wedge. Contact is established between the wedge and the curved surfaces of the holder and the shank over outer regions separated by non-contacting clearances.

摘要： A plough for winning material (such as coal) from a face has a plough body which supports a carrier for roof-level cutters. Means are provided for adjusting the vertical position of the carrier with respect to the plough body. The adjustment means comprises a worm mounted on the plough body, and a toothed rack associated with the carrier. The worm meshes with the toothed rack. The worm is driven through a reduction gear which is located on the goaf side of the carrier.

摘要： A coal plough which is movable to and fro in a mine working alongside a coal face, has floor-level cutters mounted on a carrier. The carrier is pivotable in a vertical plane about a horizontal axis perpendicular to the coal face. The carrier is pivotable between a working position, in which it bears against a first stop, and a non-working position, in which it bears against a second stop. The cutters bear against the floor of the working when the carrier is in the working position and are lifted clear of the floor when the carrier is in the non-working position. The first stop defines the level of cut of the cutters, and the second stop limits the upward pivotal movement of the carrier. The first and second stops are provided on the plough. The carrier is provided with cutter control means constituted by a peg which extends from the carrier towards the floor, the peg engaging the floor to move the carrier into the working position when the plough moves in one direction and to move the carrier into the non-working position when the plough moves in the opposite direction.

摘要： A plough for winning material from a mineral face comprises two plough bodies connected together in a tension-proof manner. The two plough bodies are provided with detachable cutters at each end thereof. A rigid beam, also provided with detachable cutters, connects the two plough bodies at a predetermined height. The beam carries a plough upper part for each of the two plough bodies. Each plough upper part is provided with detachable cutters and is pivotably mounted on the beam by means of a parallelogram linkage. Each plough upper part is guided and supported on the beam by means of a keyed connection.
