Definitions

  • This invention relates to a floor mounted mineral winning machine of the kind arranged to be located beyond the face side sidewall of an armoured scraper chain conveyor extending along a mineral face; and to a mineral winning system incorporating such a machine.
  • a mineral winning machine is reciprocated along a mineral face to extract mineral from the seam, the mineral being loaded onto an armoured, scraper chain conveyor extending along the mineral face, which conveyor serves to guide the machine along the face.
  • Extraction is usually effected by a rotary, pick-carrying cutting head mounted at one end of a ranging arm pivotally attached to the machine body; which arm is displaceable under the control of a double-acting hydraulic ram. If, as is usually the case, the machine is designed as a double-ended machine, one cutting head and arm are mounted at each end of the machine.
  • the machines are usually mounted on the conveyor in addition to being guided thereby, but the present invention is concerned with the winning of medium/thin seams, e.g. 180 cm (6 ft.) or less where the machine is floor mounted with the main body of the machine positioned beyond the face side sidewall of the conveyor and slidingly engaging the conveyor at various locations on the face side of the conveyor and usually on a toe plate of the conveyor for guidance purposes.
  • medium/thin seams e.g. 180 cm (6 ft.) or less
  • Such machines are double-ended and roll steering of these machines is effected by a pair of vertical rams, one located towards each end of the machine and each carrying a shoe to bear on, and slide along, the mine floor located beyond the face side sidewall and just cut by the leading drum.
  • a floor mounted mineral winning machine for reciprocation along a mineral face comprising an elongate machine body arranged, in use, to be located beyond the face side sidewall of an armoured conveyor extending along the mineral face at least one machine haulage unit comprising a drive sprocket, a reduction gear and a motor, the sprocket engaging, in use, a rack attached to the face sidewall of said conveyor; at least one canopy extending rearwardly from the machine body to overlie, in use, the conveyor and carrying electric/electronic/hydraulic control means for the various functions of the machine.
  • Such prior art proposals however result in a relatively long machine body, because of the need to incorporate a haulage module within the length of the machine body. Furthermore servicing and/or repair of a haulage module is relatively difficult because of this location.
  • a floor mounted mineral winning machine for reciprocation along a mineral face comprising an elongate machine body arranged, in use, to be located beyond the face side sidewall of an armoured conveyor extending along the mineral face, at least one machine haulage unit comprising a drive sprocket, a reduction gear and a motor, the sprocket engaging, in use, a rack attached to the face side sidewall of said conveyor; at least one canopy extending rearwardly from the machine body, to overlie, in use, the conveyor and carrying electric/electronic/ hydraulic control means for the various functions of the machine characterised in that the or each canopy houses a machine haulage unit.
  • a mineral winning system comprises at least one mineral winning machine as defined above, an armoured scraper chain conveyor extending along a mineral face and a rack extending along the conveyor and attached to the face side sidewall thereof, the rack being engaged by the or each machine haulage unit.
  • the location of at least one haulage unit within the canopy means that a haulage module can be eliminated from the machine body, as a result of which the overall length of the machine body can be correspondingly reduced and the attendant advantages obtained, while servicing/repair of the haulage unit(s) is rendered easier by being positioned in a more accessible location.
  • the machine is double-ended comprising a ranging arm pivotally attached to each end of the machine, each arm being under the control of a double-acting hydraulic ram, and each arm carrying a rotary, pick-carrying cutting head.
  • the canopy houses two individual and longitudinally spaced apart haulage units. The latter may each be drivable by a hydraulic motor and gearbox, or by an electric, variable speed motor. With a hydraulic drive, the machine body may house a hydraulic pump.
  • a floor mounted mineral winning machine 1 of the shearer type, comprises an elongate machine body 2 housing a main electric motor to supply power to gearheads 3 located at each end of the body 2, each gearhead supporting a ranging arm 4, which is pivotable with respect to its gearhead 3 in the known manner, under the control of a double-acting hydraulic ram 5 (one only indicated in Figure 4) pivotally attached at 6 to the arm and at 7 to the machine body 2.
  • Each ranging arm 4 houses gearing to transmit drive to a rotary, pick-carrying cutting head 8 carried at the free end of the arm.
  • the machine seats on mine floor 9 via steering jacks 10, one of which is located towards each end of the machine body 2 and the machine incorporates a guiding and trapping arm 11 engaging a guiding and trapping recess 12 in a guide beam 13 which is also provided, along an upper edge thereof, with two laterally spaced rows of teeth 14, so that the guide beam 13 also constitutes a rack bar.
  • the guide beam is attached to a face side sidewall 15 of a pan 16 which is secured end-to-end to similar pans to make up an armoured, scraper chain conveyor 17 of the desired length, flight bars 18 of the conveyor being indicated in Figure 1, with the machine body 2 located beyond the face side sidewall 15 of the conveyor 17.
  • a single canopy 19 extends rearwardly from the machine body 2 to overlie the conveyor 17, the canopy housing two longitudinally spaced apart machine haulage units 20, each unit comprising a variable speed electric motor 21, a speed reduction transmission 22, and twin, co-axial haulage sprockets 23 in mesh with the teeth 14, each sprocket 23 being rotatable about a laterally extending axis 24.
  • the beams 30 correspond in length to the pans 16 with articulated joints provided at their adjacent ends.
