Definitions

  • Such machines are Uenerally adapted to operate in conjunction with a conveyor and are adapted to be pulled along the face of a coal seam between the seam and the conveyor.
  • the machine is provided with cutters similar to ehisels which gouge tinto the coal plowing it loose and onto the conveyor.
  • the installation is ⁇ moved up toward the coal face and returned to plow out the coal on the return trip.
  • the cutters utilized in this operation and in accordance with this invention are of different shapes. Some are adapted to slit the coal face and others to cut wider kenfs.
  • the cutters have been heretofore mounted on heads pivoted so that as the machine ladvances the cutters is caused to gouge further into the coal face ⁇ and on the reverse movement of the machine, the cutters cause the head to swing back and the cutters either drag along the face or drop back away from the coal.
  • cutter heads which have cutters operating in both directions.
  • the cutters me mounted in sets angularly disposed with respect to each other so that one set cuts as the machine travels in one direction and the other set cuts when the machines direction is reversed,
  • a roof cutter so mounted that it yautomatically follows the contour of the roof by spring pressure so that if the roof lowers in spots the head will yield accordingly.
  • the lower cutters are mounted on brackets which pivot about horizontal pins so that they dip or rise ⁇ at the ends to follow uneveness of the floor.
  • lt is, accordingly, an obj-ect of this invention to provide a coal mining machine of the planer type of large capacity and which adapts itself to varying seam conditions.
  • FIG. l is a front View front elevation of ⁇ a preferred embodiment of the invention.
  • FIG. 2 is a plan view of the mining machine
  • FIG. 3 is a vertical sectional view at the line lll-lll lookin.G in the direction of the arrows;
  • FlG. 4 is a sectional view of lthe roof cutter head mounting taken at the line lV-IV looking in the direction of the arrows, and;
  • FlG. 5 is a sectional view taken at the line V--V looking in the direction of the arrows.
  • the machine of this invention is of the general type shown in Herrmann Patent No. 2,745,651 of May l5, 1956 wherein is illustrated a conveyor provided with a guide upon which the base of a planer -is adapted to glide as it is propelled back and forth with respect to the face of a coal seam.
  • this machine is provided with a base 1 which is adapted to be propelled longitudinally of a coal seam (not shown).
  • base 1 At either extremity of base 1 are brackets 1a and 1b pivotally mounted on horizontal pins 3 carried by base 1 toward its middle.
  • a cutter head 16 On each bracket 1a and 1b is mounted a cutter head 16 having cutter blades 17 of the slitting type and pivotally swingable up and down ll? Patented Jan. 21, ll
  • the cutter blades 17 thus drag along the base of the seam and form a korf to which other blades are adapted to cut. Since brackets 1a and 1b lare pivoted, the blades 17 follow unevennesses of :the flow of the working.
  • cutter heads 7 I are adapted to ⁇ out as the machine moves in either direction. They are accordingly provided with two sets of cutter blades the sets being angularly disposed with respect to each other cach set differing from the other in that the outermost sets 6 are slitter blades except for the bottommost which is of the chisel type, the inner set of blades 2t? are all chisel type blades.
  • the cutter heads 7 tip so that the blades cut in to the wall of the seam Aand those in advance slit the coal while the following cut-ter heads 7 having wider chisel blades ⁇ tend to out out larger chunks at the center.
  • the suppont for unit 21 consists of a bottom plate 2.2 suitably welded to a front plate Z3.
  • a pair of flanges 24 extending laterally serves to attach the unit to anges 25, extending from base 1, bolts 3 rbeing yadapted to secure unit 21 in place as well as pivots ⁇ for brackets 1a and 1b.
  • cutter heads S Suitably attached to the front plate 23 are a pair od cutter heads S pivoted on vertical pins 4 so that cutter heads 5 may swing into and out of cutting position.
  • Cutter Iheads 5 are adapted to operate on coal in the seam above cutter heads 7.
  • the unit Z1 is used when the seam is relatively deep. The machine can operate on thin coal seams by removing uni-t 21.
  • the roof -cutter head 8 At the center is mounted the roof -cutter head 8 so arranged that it automatically follows the roof contour.
  • it has a special mounting which consists of a pair of telescopically arranged tubes 28 and 29, tube 28 being welded at the bottom to base plate lZ2 and Ythe vouter tube 29 extending vertically.
  • a head 39 upon which is mounted ⁇ a guide 31 carrying a pivot pin 32 tilted lbackwardly and eccentric to the tube 29.
  • Cutter head 8 is pivoted on pin 32 the upper face of guide member 31 being so shaped as to permit head 8 to slide freely ⁇ as it swings back and forth.
  • Head 8 is provided with blades 33 in this instance in two sets of two ⁇ blades each the sets being set angularly with respect to each other and extending radially from the direction of pin 32 and angularly with respect to each other.
  • the angularity of pin 32 with respect to the vertical causes blades 33 to tilt upwardly as head S rocks in one direction or the other.
  • a movable cutter 11 fitting in a dovetail slot 34 ⁇ and held therein by a set screw 35.
  • Cutter 11 is provided with a pair of points as indicated in PlG. 2, one or the other of the points lifts, depending upon the direction of rocking ⁇ of cutter head 8.
  • the mounting of cutter head is adapted to cause the head to press against the roof of the seam and to this end a spring 12 is provided to press tube 29 upwardly.
  • the compression of spring ⁇ 12 can ⁇ be regulated.
  • a screw 13 having a head 40 bear-ing against the end of spring 12 is adapted to compress spring :12 by turning of a nut 112 engaging screw 13 and mounted between two plates 41 and 42 mounted within tube 2-9. Turning of screw 113 is prevented by a notched head 43 engaging bars 15 mounted longitudinally Within tube 29.
  • screw 13 moves up or down depending upon the direction of nut turning to compress or relieve spring 12.
  • a coal mining machine of the planer type adapted to be propelled in either direction longitudinally at the face of -a coal seam, including a horizontally extending base containing cutting means operatively disposed thereon for extractive engagement with the coal seam, the improvement which comprises a roof cutting arrangement positioned on said base, said roof cutting arrangement including ⁇ an elongated vertically extending mounting means of adjustable height xedly attached at the lowermost end thereof to said base, a roof cutter head pivotally disposed on the uppermost end of said mounting means for pivoting along a path in an inclined plane disposed between the vertical ⁇ and lthe horizontal, and cutter blades mo-unted on said cutter head for pivoting therewith, said mounting means being resiliently urged such that said uppermost end is vertically displaceably positioned a predetermined adjustable distance above said base, and said cutter head :and said cutter blades both being secured :from angular displacement from the inclined plane in which said path is situated yet both being .resiliently displaceable in vertical direction
  • said cutter head is disposed pivotally on the uppermost end of said mounting means by means or a tilted pivot angularly and eccentrically set at said uppermost end of the mounting means to permit pivotal movement of said cutter head along said path with said inclined plane intersecting both 'the vertical axis of the mounting Imeans and the horizontal yaxis at the uppermost end of said mounting means, said cutter blades being provided on said cutter head ra ially respect to said tilt-ed pivot and angularly with respect to each other whereby pivoting of said cutter head elevates the cutting edges of said cutter blades.
