摘要： A cutter bit assembly is composed of a carrier or holder secured or integral with a coal plough and a cutter part detachably secured to the holder. The holder has a head piece with opposite plane faces extending transversally to the cutting direction. A bore in the head piece opens to these faces and extends parallel to the cutting direction. The cutter part has a plane face engageable on one of the transverse faces of the head piece and a projection and recess on these engageable faces prevents rotation of the cutter part. A threaded member either integral with or separate from the cutter part extends through the bore in the head piece and receives a nut bearing on the other of the transverse faces and used to detachably secure the cutter part to the head piece.

摘要： A coal plough is composed of two spaced-apart interconnected bodies which engage on a guide and which are moved along the guide to strip coal from a coal face. Each body is provided with various sets of cutter bits located at both its end regions and a floor cutter adjustable to control the height of cutting. The cutter bits at the inner face end regions of the bodies project further outwards towards the coal face than the other bits. During operation when the bodies move in one direction along the guide, cutter bits at the forward outer end region of the leading body cut into the coal face and the following-up cutter bits at the forward inner end region of the lagging body also cut into the face. The remaining cutter bits do not engage on the coal face.In this way the cutting operation is performed by both bodies and similarly both bodies can assist into transferring the coal detached from the face over the guide and into a scraper-chain 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.

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 floor cutter bit for a coal plough has a cutter body which supports a floor cutter plate and a coal-face cutter plate. The two cutter plates are made of hard metal, and have respective cutting edges. The cutter plates are soldered into respective apertures in the cutter body. The cutting edge of the floor cutter plate extends the entire length of the floor cutter plate, and the floor cutter plate extends over the entire width of the cutter body. The base of the coal-face cutter plate adjoins the upper side of the floor cutter plate thereby defining an L-shaped cutter plate configuration. The depth of the floor cutter plate, at least in the region where the two cutter plates meets, is greater than about 15 millimeters.

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： 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.
