摘要： A drum cutter mining machine includes a machine frame with a winch having a drive wheel to engage a rack or chain which extends along the path of travel by the mining machine to propel the machine along a mine face. The mining machine is made up of discrete units which include a machine body and machine housings joined to opposite sides of the machine body. The winch is either coupled through a drive train with a feed drive motor or coupled to the drive motor for cutter drums. The machine housings each support a pivot shaft coupled by an arm to a drum cutter. One of these housings includes a removable end cover and a recess adapted to receive a support housing for a spur gear system used to transmit torque from a feed drive motor to a reduction gear system which is, in turn, coupled to the drive wheel of the winch. In one embodiment, a removable end cover on the machine housing provides access to the feed drive motor. The feed drive motor is arranged so that the rotational axis of its drive output shaft extends transversely to the stow side of the machine frame. In another embodiment, the reduction gear system is arranged at one side of the pivot shaft for the cutter drum while the drive motor therefor is arranged at the other side of the pivot shaft and coupled thereto through the spur gear system. In a further embodiment, the reduction gear system is disposed between the feed motor and the pivot shaft.

摘要： A drum cutter-loader machine includes discrete units joined together by tie bolts extending transversely to the direction of advancing movement along a face conveyor. The units in succession from the stow side to the working side include a gantry casing supporting winch drive motors and straddling the face conveyor, a transmission box, a winch casing and casing carrying actuators coupled to arms carried by pivots at opposite ends of the winch casing. The arms carry cutter drums driven by motors supported by the arms. A toothed rack at the working face side is engaged by drive wheels driven through gearing in the winch casing and transmission box by the winch motors. The gantry casing is supported at the stow side through runners that engage a guide rail. In one embodiment, the machine is supported by rollers at the working face side on the toothed rack. In a further embodiment, the machine is supported by rollers at the working face side on a machine track.

摘要： A screw-type cutter drum is provided having helical ribs on the drum body with cutter picks on the ribs and on the end of the drum. The cutter picks at the end of the drum are arranged in sets spaced apart to coincide with the ends of the ribs and the cutter picks of each set are equally spaced apart angularly and placed at different radial distances from the axis which decrease in the direction of rotation.

摘要： In order to overcome problems associated with drum cutter-loader mining machines having a cutting drum mounted at one or both ends of the machine on pivotable support arms and further having cutting drum drive motors positioned outside of the machine body, there is provided a unique support arm system for adjusting the height of the cutting drums and their associated drive motors which neither reduces the debris pass-through cross-section of the machine bridge nor impairs the height adjustability of the cutting drums. The support arm system for each cutting drum and drive motor includes a first support arm section pivotally mounted at one end thereof to an end of the machine body and a second support arm section pivotally mounted to an opposite end of the first arm section. The second support arm section carries at least the cutting drum drive motor at one end thereof and the drive motor of each support arm is positionable inside the coal seam winning track.

摘要： A drive gear of a drum-cutter mining machine engages a rack device extending along the working side of a face conveyor to propel the mining machine along a mine face. Spanning each joint between conveyor tray sections is a bridging rack segment with leg extensions interlocked with recesses formed in extended end members of non-bridging rack segments each of which extends along a single conveyor tray section and is secured thereto by bolts. Rack teeth are formed by spaced-apart pin members carried by lugs outwardly of the face conveyor. The ends of the pin members at the face conveyor for the bridging rack segments are carried by U-shaped plates with a tongue plate engaged behind the extended end members of the non-bridging rack segments. The ends of the pin members at the face conveyor for the non-bridging rack segments are carried by flanges having lower, outwardly-bent sections extending toward the mine floor to form a ramp at the working face side of the face conveyor.

摘要： A drum cutter includes a machine body having at the opposed ends, pivot shafts extending parallel to the mine floor at right angles to the direction of travel by the machine body along a coal face. Two support arms each include two laterally-spaced bores at one end thereof to selectively receive a projected portion of a pivot shaft extending toward the mine face. A lever is mounted onto each of the support arms adjacent the bores in the end thereof. A cutter drum projects from the free ends of the support arms at the coal side of the machine body. Hydraulic jacks, supported by the machine body, are coupled to the levers for pivoting the arms to position the cutter drum supported thereby. A motor is supported within a casing attached to the stow side of each support arm. The motor is coupled through gearing to the cutter drum. The projected end of the casing is supported by a bearing member secured to the extension of the machine body and provided with a bore to receive the pivot shaft.
