Definitions

  • the cutting heads ofthe machine face the coal .face and ⁇ as the machine passes -the coal facethe cutting heads plane olf coal which is'removed from the vicinity of the machine by means -of a conveyor.
  • this invention resides, in one of its broadest aspects, in? a coal mining machine having a single drive mean-s and at least one cutting head movable with relation to the whole of said mining machine, wherein said single drive means both propels said mining machine along the'c'oal face and also causes said cutting head to move with relation to said mining machine as a whole.
  • FIG. 1 is an elevation in schematic representation of an apparatus in accord with this invention
  • FIG. 2 is an elevation in schematic representation of the apparatus of FIG. 1 shown in greater'detail.
  • FIG. 3 is a side elevation of an apparatus according to this invention similar to the apparatus shown in FIG. 2.
  • a mining machine assembly is there shown viewed lfrom the direction of the coal face upon -which the mining machine is operating.
  • This mining machine assembly is shown as comprising a guiding conveyor means 2 resting upon the mine tunnel floor or upon a suitable platform erected on such floor.
  • the mining machine itself 6 is shown operatively associated-with the conveyor means 2, and suitably mounted thereon.
  • a movable cutting head 12 is shown mounted on the cutting machine l6 and connected thereto by a supporting arm 42.
  • An endless driving belt is shown operatively connecting the mining machine ⁇ 6 to machine driving means 51 and 52 therefor, and conveyor driving means 53 and 54 are shown suitably near the machine driving means.
  • a ixedly positioned guide belt 60 suitably anchored at stanchions 55 and 56, is shown operatively associated with the mining machine 6.
  • the endless belt 50 is connected to the mining machine 6 through a power transmission roller 46.
  • a power transmission roller 46 Suitably two rollers 45' may be positioned along the driving belt for purposes lto be described hereinafter.
  • the movement of the driving belt 50 about the power transmission roller 46 provides the power'to drive the cutting head 12.
  • Power may be transmitted 4 from the roller 46 to the cutting head 12 through suitconventional system for power coupling, such as hydraulic or electric, or via gears, pulleys or belt drives.
  • roller 46 may be driven at a speed completely independent of the driving speed of the roller 46', and by which the roller 46 can 'be idle during a time when the roller 46' is being powered. While this latter described relative independence of operation of the rollers 46 and 46' is a desirable attribute of this invention, it is by no means critical to the operation hereof.
  • the rollers 46 and 46' must be power coupled so as to be driven by the same power source, but this coupling may be on a fixed relationship of power basis, if desired.
  • the power means 51 and 52 drives the roller 46' through the driving belt 50; the rollerv46' drives both the cutting head 12 and the drive roller 46; and the drive roller 46 accomplishes the lateral movement of the mining machine 6 by bearing upon the iixedly positioned belt 60.
  • rollers 45 and 45' mentioned above may be used, if desired, and can serve a useful function. By spacing either set of the rollers 45 or 45' close together and about the respective roller 46 or 46', the belt S0 or 60 operatively associated with the roller 46 or 46 can be made to more totally wrap the roller 46 or 46' and therefore pro- .vde for more efficient power transmission between the belt and its associated roller. It is within the spirit and scope of this invention either to have or not to have the rollers 45 and 45. Where these rollers or either of them are present, they may be idler rollers or may be used as power take-off or drive means, as the case may be. They may be positioned as shown in the drawing, that is, so as to provide a tight loop about the roller 46 or 46' or one of them may be used such that the belt forms a more or less pronounced S about it and its associated roller 46 or 46.
  • roller 46 can drive both the cutting head 12 and the mining machine 6 by putting both belts 50 and -60 in operative association with either the single roller 46 or with the combination of the rollers 45 and 46.
  • the drive belts 50 and 60 are suitably of the chain type. They may be of materials other than chain, if desired, but the use of chains has been found to give excellent results. It is preferred to use link chains adapted to be used with sprockets and to provide the rollers 45, 45', 46 and 46', as sprocket gears, such that positive drive action can be transmitted between the rollers and'the belts with little or no slippage being incurred. It is often desirable to provide means for changing the position of the cutting head with relation to the mine tunnel floor or the conveyor guide. This is provided for by the practice of the instant invention as shown in FIG. 2. The height and position of the cutting head 12 can be regulated by the cylinder and contained piston assembly 18, which can suitably be operated by hydraulic means controllable either directly or remotely as the case may be in the known manner.
  • FIG. 3 a slightly modified apparatus according to this invention is shown, wherein several cutting means are utilized in connection with a single mining machine.
  • a mining machine 6, of the general type described above, is equipped with a planing head 40 for removing coal from the lowest part of the coal face 61.
  • a rotating cutting tool 41' is suitably affixed to-the roller 46' in such position that ithremoves coal from the coal face just above that part thereof being cut by the planer.
  • a second rotating cutting head 12 is mounted and operated as described above with reference'to FIGS. 1 and 2.
  • a single machine4 can be operated to mine an entire coal face simultaneously by positioning a sufficient numberpof cutting heads in ⁇ proper relationl on a single mining machine.
  • a mining machine assembly comprising a mining machine body at least one cutting means mounted on said body movable with relation thereto; drive means for said assembly which is adapted to cause said body to move with relation to a mine face and is also adapted to cause said cutting means to move with relation to said body and with relation to said mining face; the improvement which comprises providing two belts operatively associated with said machine assembly, the first of said belts being an endless belt operatively associated with drive means therefor and with said movable cutting means through a first roller mounted on said body, and the second of said belts being substantially fixedly positioned about a roller means on said machine body, which second roller means is coupled to said first roller means through a variable power coupling means.
  • variable power coupling means is an hydraulic coupling.
  • each of said belts is a sprocket chain and eac of said rollers is a sprocket roller.
