Definitions

  • the invention relates to mining and can be used for extracting ore from strata with complex deposition structures.
  • the claimed invention is directed to solving the problem of providing bulk and selective ore extraction with one and the same machine.
  • a face-working machine comprising a housing and two actuating elements disposed at the ends of the housing, the actuating elements being in the form of arms rotatable in the vertical plane and provided with a built-in drive and a cutting screw conveyor ("Glutler", No.8, 1992, p.7).
  • the most pertinent technical solution adopted as the prototype is a machine (U.S.S.R. Patent 1553670) comprising a housing and two actuating elements hinged thereon, the actuating elements being in the form of screw conveyors with drives for extracting the mineral, and a cutting drum having a vertical axis of rotation for extracting rocky interstratification.
  • the cutting drum with the drive is disposed on an additional support frame hinged to the machine. When turning relative to the support frame, the cutting drum occupies a position of being ahead of the screw conveyors in the direction of the face, and gets positioned behind them in the course of work.
  • a face-working machine comprises the following set of substantial features : a housing and two actuating elements disposed at the ends of the housing, the actuating elements being in the form of arms rotatable in the vertical plane, provided with a built-in drive and a cutting screw conveyor; each arm is connected to the housing of the machine by means of a bracket at one end of which the arm is hinged, while the other is movably mounted in the guides of the housing of the machine, enabling frontal movement of the arm against the face with the help of a hydraulic cylinder by an amount equivalent to the intake capacity of the screw conveyor.
  • each arm is connected to the housing by means of a bracket at one end of which the arm is hinged, while the other is movably mounted in guides of the housing of the machine, enabling frontal movement of the arm against the face with the help of a hydraulic cylinder by an amount equivalent to the intake capacity of the screw conveyor.
  • the invention also has inventive height because a combination of features, which is the connection of each arm to the housing of the machine by means of a bracket at one end of which the arm is hinged, while the other is movably mounted in guides of the housing of the machine enabling frontal movement of the arm against the face with the help of a hydraulic cylinder by an amount equivalent to the intake capacity of the screw conveyor, solves the problem of the invention : to broaden the sphere of application and increase the efficiency when working seams by a selective method, and also to enhance the technical potential of the machine in bulk and selective methods of extracting minerals.
  • These features are interconnected in such a way that one of them is removed, the technical result, which is provided with the invention, disappears.
  • the set of substantial features, characterizing the substance of the invention can be used in mining by obtaining a technical result lying in efficiently working seams of a mineral by the bulk method and the selective method, leading to an achievement of the object set, thus permitting one to come to the conclusion that the invention meets the criterion of "industrial applicability".
  • the claimed face-working machine comprises a housing 1 with feed mechanisms 2 and 3, two actuating elements in the form of arms 4 and 5 having a built-in drive 6 and 7, and screw conveyors 8 and 9.
  • Each arm is connected to housing 1 by means of brackets 10 and 11. Arms 4 and 5 are hinged at one end of each bracket, while the other is mounted in guides 12 and 13 of housing 1.
  • Hydraulic cylinders 14 and 15 provide frontal movement of the brackets 10 and 11 together with arms 4 and 5 against the face by an amount equivalent to the intake capacity of the screw conveyor.
  • the machine operates as follows. For extracting seams of a mineral by the bulk method, both arms 4 and 5 are pushed back from the face into the machine with the help of hydraulic cylinders 14 and 15. At the same time brackets 10 and 11 move along guides 12 and 13, providing the necessary equal reach of screw conveyors 8 and 9 with respect to housing 1. In this state the machine is ready to work in the bulk method.
  • one or the other screw conveyor For working seams in the selective method, one or the other screw conveyor must periodically obtain frontal movement against the face. So, when working a seam which has a rocky interstratification in the middle section thereof, the order of working the machine is as follows : one of the screw conveyors occupies an upper position and, with the help of bracket 10 and cylinder 14, is pushed out frontally against the face along guides 12 by an amount equivalent to the intake capacity of the screw conveyor.
  • the upper screw conveyor is moved out against the face by an amount if its intake capacity and provides an extraction of the immediate upper productive batch of the seam, while the lower screw conveyor, which, with respect to the face, lags behind the upper screw conveyor by an amount of its intake capacity, works off the lower productive batch of the seam.
  • the main conveyor together with the machine moves against the face by an amount of its intake capacity, while the upper screw conveyor is pushed back into the machine; as this takes place, both screw conveyors provide an extraction of thr rocky interstratification.
  • the third and fourth operations alternate.
  • the claimed invention can be utilized in the national economy, and in comparison to the prototype, it has the following advantages :
  • the sphere of application of such a machine is wider, i.e. it can be used without any structural change in both the bulk and selective methods.
  • the efficiency of its utilization is increased due to the universal construction of its activating elements, which provide an extraction of productive batches and rocky interstratifications.
  • the technological potential of the machine has been expanded because its actuating element can expeditiously regulate the breadth (range) of its intake capacity.
