Definitions

  • the present invention relates to a cutter intended in particular for short pruning.
  • the cutter allows the felling of successive sections of mines in a return trip between two galleries, or from a gallery towards a dead end.
  • Conventional cutters are generally high power devices designed for long cutting, that is to say the distance between the two galleries is of the order of 200 to 400 m. These cutters have lengths of the order of 8 m much greater than the dimensions of the galleries and this precludes, at least at one of the cutting ends, from bringing the arm which carries the slaughter drum into a position where the drum could start the layer of charcoal from the open area of the gallery. For this reason it is necessary to dig a "niche", either by special means, or even more often manually, to open access to the slaughter drum.
  • the present invention makes it possible to avoid these drawbacks thanks to a shearer of great maneuverability and compactness of which all the particularities are designed to be adapted to powers of 2.5 to 3.5 m and short sizes and to make superfluous the manual niche digging at the ends of the waist.
  • the present invention therefore relates to a cutter comprising a chassis, a gear motor, a felling drum offset laterally with respect to the chassis of the cutter and supported at one end of an arm articulated by its other end at one end of the geared motor, this arm being actuated by a jack, characterized in that the arm connected to the geared motor and supporting the drum extends laterally relative to the chassis in a direction of advance of the felling, the direction of the arm being modifiable using the jack so as to allow different heights of felling without practically the arm protruding from the rear of the chassis during felling.
  • Another object of the invention is to allow the release of the felled coal to be carried out laterally under the machine.
  • the cutter comprises a winch for pulling the cutter which can be secured to one end of the chassis of the machine which does not support the articulation of the arm.
  • a final goal is to offer a machine that is reversible, that is to say whose size is such that one can start from a gallery located to the left of the vein to be felled or in the other arrangement a gallery located to the right of the vein to be cut down.
  • the chassis comprises at each of its ends means for receiving and fixing, alternately the winch or the geared motor assembly carrying the articulation of the arm at one end of the chassis.
  • the winch fixed to one end of the frame comprises a gear cooperating with a fixed rack of the installation and near this gear a support shoe resting on a rail of the installation.
  • the chassis comprises, along the longitudinal face opposite the support arm, two fixing lugs for pad arranged near each end of the chassis.
  • FIG. 6 represents a left gallery 10 and a right gallery 12 separated by a coal seam 13 which one seeks to exploit by traditional means.
  • These traditional means consist of a shearer comprising a main body or chassis 2, at one end of which is mounted an articulated arm 3, the other end of which supports a drum or felling cylinder 4.
  • the galleries 10,12 are as small as possible and allow the passage of the main body of the cutter.
  • the present invention overcomes the obligation to dig this niche.
  • FIG. 1 represents an end view of the gallery 10 in which the cutter according to the invention is arranged parallel to the vein 13 to be attacked.
  • the dotted line A represents the gallery volume that should be cleared in addition to allow for example the arm 3 of the cutter to come into a position which corresponds to the position of the prior art. It is therefore easily understood that the arrangement of the arm of the cutter according to the invention allows a considerable saving in digging, either of the gallery or of the niches.
  • the felling drum 4 of the cutter driven in rotation rotates in the direction indicated by the arrow R, while the whole of the cutter constituted by the body 2, the gear motor 20, the arm 3 and the drum 4 , moves with the arm in position I corresponding to the upper felling in the direction of the arrow D.
  • the device also includes a conveyor belt 5 used to evacuate the slaughtered materials and at the end of this belt a motor unit 6 and a weir device which makes it possible to dump the slaughtered materials on a second conveyor belt 7 in a direction perpendicular to the first, that is to say say parallel to the direction of the gallery 10.
  • FIGS. 2 to 5B it can be seen that the slaughter drum 4 is arranged laterally with respect to the support arm 3 which is itself articulated on the side of the gear motor 20 of the machine.
  • the length of the articulation arm 3 and the diameter of the drum 4 are such that the arm and the drum in the working position II, do not protrude much from the silhouette of the chassis of the machine.
  • the felling drum is also released inside the gallery 10 and is ready to start a new section of the mine from the side.
  • the drum 4 has at its periphery a helical ramp 40 oriented so that when the drum rotates in the direction indicated by the arrow R, the materials torn off by the helical ramp 40, are moved towards the chassis 2 of the machine and the treadmill 5.
  • the treadmill 5 is framed on either side by a lower rail 50 and an upper rail 51 visible in Figures 3 and 4 On this upper rail 51 is disposed a rack 53 and adjacent to this rail is placed a chute 54 in which a cable-carrying chain 52 is deposited.
  • This cable-carrying chain 52 makes it possible to ensure by means of the cable 25 ' power supply to the geared motor group 20 arranged on the chassis 2 of the machine.
  • a hydraulic cylinder 21 articulated to the chassis at a fixed point 210, disposed near the end of the chassis.
  • This chassis end will receive a winch 8 cooperating with the rack 53 so as to allow the driving of the cutter along the section.
  • the jack has a movable end connected to a link 22, the other end being articulated to an axis 320 secured to an ear 32 bolted on an extension of the arm 3 relative to the articulation axis 30 of this arm on the gear motor 20.
  • the chassis supports at its lower part a shoe 90 disposed approximately in the middle of the length of the chassis and along the longitudinal side of the chassis adjacent to the support arm 3 of the harvester head 4 Along the longitudinal side opposite this pad, there are two studs 23,24 on which a second pad 91 can be mounted which will come to bear on the upper rail 51.
  • the pad 90 in turn comes to rest on the lower rail 50.
  • the stud used for fixing the upper shoe 91 is the one arranged near the articulation axis 30 of the arm 3, while the pin 23 disposed near the winch 8 is not used.
  • the winch 8 is placed at the end of the chassis opposite to that receiving the articulation axis 30 of the arm 3 and this winch 8 is arranged so that the gear 81 is placed near the longitudinal side of the opposite chassis on the side along which the arm 3 supporting the felling head moves.
  • This gear 81 engaging with the rack 53 to tow the machine in the direction of arrow D for the upper felling and in the direction of the arrow G for the lower felling.
  • the arrangement of the pad 90 in the middle of the chassis is advantageous because it frees the space located under the chassis at the front of the axis of rotation of the felling drum 4 so as to allow this drum to bring the materials in the direction of the conveyor belt 5 which moves between the three support points of the chassis 2 of the cutter.
  • FIG. 5B shows another embodiment of the support for the cutter on the rail 50.
  • two pads 92, 83 which come to bear on the lower rail 50 are used.
  • the two pads are fixed to the two ends of the length of the chassis 2.
  • the two shoes give better stability to the cutter on the rails but have the disadvantage of cluttering the space located under the chassis.
  • the chassis comprises means of reception and fixing not shown, making it possible to place the gear motor / articulation arm assembly at each end of the chassis.
  • the motor-reduction unit will be fixed to the chassis at its left end.
  • the right end will then be equipped with the winch ensuring the advance system of the cutter.
  • the winch will be positioned by fixing means identical to the fixing means of the motor-reducer / articulation arm assembly on the same end or by fixing means specific to winches different from those of the motor-reducer.
  • the machine would be mounted symmetrically, that is to say that the axis of articulation of the arm 3 would be placed in the place where the winch 8 is depicted (FIG. 2) and in this case we would use the ear 31 bolted to the arm 3 symmetrically to the ear 32 relative to a longitudinal axis of symmetry of the arm .
  • This lug 31 would be connected to the rod 22 which is itself connected to the jack 21 which in this case would be attached to a fixed point arranged near the stud 24 and no longer to the fixed point 210 which is arranged near the stud 23 It is quite obvious that in this case, the geared motor group would be oriented in the opposite direction to the direction shown in FIG. 2. On the other hand, the drum 4 relative to the conveyor belt and consequently to the longitudinal sides of the chassis of the machine will remain on the same side.
  • Figure 1 is shown along the dotted line At the size of the gallery that should be dug to allow a machine of equivalent size but operating according to the principle of the prior art, that is to say with the arm in front of the chassis, to come to position to attack the vein 13.
