摘要： A loading arm assembly for directing material removed by a mining machining having a cutting head and a conveyor assembly includes one or more wear resistant plate assemblies at a terminal end of the loading arm. The wear resistant plate assembly includes a wear resistant plate arranged on a surface of arms of the loading arm assembly designed for directing the material to the conveyor. The assembly also has wear resistant inserts along a bottom surface of at least the arm end to protect the bottom surface of the arm from wear as well as the attachment of the wear resistant plate to the arm end.

摘要： A mobile mining machine for cutting a tunnel in rock has a wheel-like cutterhead assembly supported by a pitch boom assembly that causes movement of the cutterhead assembly in the vertical plane. A swing boom assembly supports the pitch boom assembly and is supported by the base frame of the mobile mining machine. The swing boom assembly causes movement of the cutterhead assembly and the pitch boom assembly in the horizontal plane. During mining, a fixed front support and a fixed rear support anchor the mobile mining machine in the tunnel with front and rear crawlers raised from the tunnel floor. During re-gripping, the front and rear crawlers are lowered to support the mobile mining machine and the fixed front support and fixed rear support remain in contact with the tunnel floor. During tramming, the front and rear supports are raised for transportation of the mobile mining machine on the crawler. A movable muck apron assembly having pivoting apron wings and an integral muck hopper is located on the front portion of the mobile mining machine.

摘要： The loading ramp (1) of a heading machine or longwall shearing machine has swivelable loading arms by means of which the cut material is removed onto a conveying means. The surface of the loading ramp (1) can be increased by outwardly swivelling of parts (2). The loading arms (5) are driven by using a pivotal point (6) on a rotary disc (7), noting that a further swivel point (12) is provided outwardly of the circle described by a rotary pivotal point (6) on the rotary disc. The loading arm (5) is guided in a shiftable manner at the swivel point (12) and sweeps when driving the rotary disc (7) over a removal area (15, 18) defined by the relative position of the pivotal point (6) and the swivel point (12). The swivel point (12) is connected with the laterally extendable part (2) and is displaced together with the laterally extendable part (2) thus varying the removal area (15, 18).

摘要： A mining machine for dislodging solid material from a mine face includes a body portion mounted on endless tracks and a boom member extending forwardly from the body portion with a cutter drum member rotatably mounted on the front end of the boom member. An endless conveyor mechanism is positioned in a longitudinal trough member and conveys dislodged material from the front of the mining machine. A gathering platform extends forwardly from the body portion and the conveyor mechanism and is positioned rearwardly of the cutter drum member. A plurality of rotatably mounted gathering disc members are positioned rearwardly of the forward transverse edge portion on the gathering platform. The gathering discs include a first pair of large discs that are positioned oppositely of the longitudinal axis of the conveyor mechanism. A second pair of smaller gathering discs are positioned laterally of the large gathering discs adjacent the lateral edge portions of the conveying platform. A drive mechanism mounted on the gathering platform is drivingly connected to the gathering discs so that the small gathering discs rotate in a direction opposite to the corresponding large gathering discs. The dislodged material is directed onto the gathering platform and is fed by the small gathering discs onto the large gathering discs and therefrom into the trough member and onto the conveyor mechanism. The gathering discs may be driven by a single motor connected to a large disc with the remaining discs connected by meshing spur gears. In another embodiment, each of the large discs may be driven by separate motors with drive trains connecting the small discs to the respective motors.

摘要： A continuous mining machine particularly adapted for low overhead coal seams having a relatively small diameter cutterhead of the non-oscillating or fixed head type driven by chains that also cut coal and convey it rearwardly to a gathering head mounted on the front of the machine. The gathering head carries a pair of counter-rotating discs having vanes cooperating with conveyor fences for sweeping and discharging coal to a conventional conveyor mounted on the machine chassis.
