摘要： A cylindrical drum assembly is rotatably mounted transversely on the front of the boom member of a continuous miner. The drum assembly comprises a pair of independently operable drum sections. Each drum section is driven through an input shaft connected to a motor. The drum sections may be connected by a coupler to form a unitary drum assembly which may be operated by only one of the motors. Torque is transmitted from the input shafts to a bevel gear rotatably supported in the drum section. The bevel gear is nonrotatably connected to a sun gear which in turn drives a plurality of planetary gears connected to a cylindrical planetary cage with a bore defining an inner surface. The cage is connected to a cylindrical inner housing on its outer surface and to an output shaft on its inner surface through a cylindrical shear coupler. A puller shaft is provided to remove the output shaft and the shear coupler.

摘要： A self-propelled continuous mining machine which includes a mobile frame assembly having a material dislodging device, and a conveying system. A dust collecting system is positioned on the mobile frame assembly for inducing a flow of air through a duct system. As material is dislodged from a mine face, the dust collecting system draws airborne dust created by the dislodging device through the duct system and into the collecting system mounted on the mobile frame assembly. The duct system has two sets of vertical walls each connected to and spaced by a horizontal wall with one set of vertical walls fitting channel-like into the other set of vertical walls. The duct assembly has a gasket, seal or other means of preventing airborne dust from escaping through the two sets of vertical walls. The duct assembly is expandable to increase the capacity of the duct system.

摘要： A boom mounted cutter drum assembly of a continuous mining machine includes an intermediate drum section and a pair of end drum sections. Spray nozzles on the cutting elements of the cutter drum assembly direct liquid spray at the mine face as mine material is dislodged to suppress dust and frictional ignition. Liquid for the spray nozzles is supplied on the mining machine through a stationary housing positioned between the intermediate drum section and the end drum sections. Water is conveyed through ports in the housing to a rotary seal assembly having stationary and rotating components. The ports are sealed by O-rings which communicate with passageways that divert liquid leakage at the rotary seal assembly away from the gearcase. The rotary seal assembly is surrounded by lip seals in the gearcase to separate the liquid passageways to the spray nozzles from the lubricant supplied to the gearcase. The lip seals communicate with the passageways vented to atmosphere so that any liquid leakage is diverted away from the gearcase. The lip seals exposed to the flow of liquid through the rotary seal assembly are also lubricated to maintain the seals operational during periods when liquid is not supplied to the spray nozzles. The lip seals and O-rings surrounding the rotary seal assembly also act as redundant liquid seals to prevent liquid from contaminating the gearcase.

摘要： A continuous mining machine includes a mobile body portion with a cutter drum member rotatably mounted on the front of a boom member which extends forwardly of the body portion. The cutter drum member has an intermediate drum section and a pair of canted end drum sections. Driven input shafts extend through openings between the intermediate section and the end drum sections. Each input shaft is drivingly connected to a first stage of a two stage planetary gear assembly which surrounds an end drum drive shaft that extends the length of each end drum section. A second stage of the planetary gear assembly is drivingly connected to and is axially aligned with the first stage to transmit rotation outwardly to the end of the end drum section. A shearable driving coupling is axially positioned on the end drum drive shaft at the end of the end drum section. An external portion of the drive coupling is connected to the second stage and an internal portion is connected to the end drum drive shaft. The drive coupling transmits rotation from the second stage to the end drum drive shaft and therefrom to a drive shaft for rotating the intermediate drum section. In the event the load on the end drum section during the mining operation exceeds a predetermined magnitude, the drive coupling shears to prevent damage to the other drive components under overload conditions.

摘要： A self-propelled mining machine includes a mobile body portion with a boom extending forwardly therefrom. The boom rotatably supports a rotatably driven cutter drum having peripherally extending cutting elements. The boom member includes a trough formed by inclined sidewalls. The inclined sidewalls are positioned in space relation and extend upwardly on opposite sides of the receiving end of a conveyor that extends continuously the length of the machine body portion. The sidewalls slope downwardly toward the lateral edges of the conveyor receiving end and form a material receiving bin or hopper. The receiving end of the conveyor forms the floor of the hopper. The front end of the hopper extends the length of the cutter drum. Suitable drive means rotate the cutter drum to dislodge material from a mine face and direct the dislodged material by rotation of the cutter drum over the cutter drum and rearwardly into the hopper. The dislodged material is directed down the inclined sidewalls of the hopper onto the receiving end of the conveyor. The conveyor transports the dislodged material rearwardly on the mining machine to a discharged end of the conveyor. The boom member together with the receiving end of the conveyor and the hopper are pivotally movable with the cutter drum member as the cutter drum is raised and lowered to form a shear cut in the mine face.

摘要： A prime mover of an underground mining machine is propelled by motor driven endless tracks that are operated in unison or independently to effect forward and reverse movement of the machine and turning of the machine. Drive is transferred to each track from a motor mounted in a traction case on each side of the machine to an input shaft through first and second stage planetary assemblies to a sprocket assembly that rotatably supports the respective tracks. A planetary carrier of the first stage planetary assembly is longitudinally movable under a spring force to apply a braking force through a brake disc to a brake plate extending from the input shaft. Fluid pressure in the traction case opposes the spring force to normally maintain the planetary carrier removed from braking engagement with the brake disc. In the event the fluid pressure drops below a preselected level, the spring force moves the planetary carrier longitudinally to actuate the brake disc assembly to interrupt rotation of the input shaft and brake the vehicle.

摘要： A self-propelled boring type mining machine includes a mobile frame and a pair of spaced apart drive shafts that extend forwardly from a gear box mounted on the frame. A pair of rotary boring heads are nonrotatably connected to the pair of drive shafts and are operable to cut a pair of bores in a mine face to dislodge the mine material. Cusps formed at the mine roof and floor are dislodged by upper and lower cutter chains that are carried by upper and lower cutter bars movably positioned on the front end of the frame. Cutter bar extensions are movably positioned on both sides of the upper and lower cutter bars by control links pivotally connected to the extensions and the mobile frame. The upper and lower cutter bars are vertically extended and retracted by piston cylinder assemblies. Movement of the cutter bars is transmitted to the cutter bar extensions which are guided on the respective cutter bars along combined horizontal and vertical paths. Thus the cutter bar extensions are automatically moved to an operating position corresponding to a preselected position of the cutter bars for supporting the cutter chains in a preselected cutting position on the mobile frame.
