Definitions

  • the invention provides that below the chisel fixed in the axial direction a piston pump is arranged between the latter and the abutment on the extraction tool, the movable part of which is formed directly or indirectly above the bit holder.
  • the piston pump can be easily removed when the piston pump is assigned to the bit holder when maintenance work becomes necessary taken and checked.
  • the chisel holder 1 is fastened so that it can be swiveled in the plane of the drawing, for example by means of two connecting elements 7, relative to the extraction tool 6.
  • the connecting elements 7 are each rotatably supported at the end points in the predetermined plane.
  • the mobility of the chisel holder 1 is, however, also to be understood as being displaceable according to FIG. 2 on the cutting head 6.
  • the chisel 2 In the position shown in FIG. 1, the chisel 2 is not in engagement with the rock or mineral.
  • the pump chamber is filled with water in the low pressure range via the water supply lines or channels and hoses 16.
  • the chisel holder 1 When the chisel 2 is engaged in the rock or mineral, the chisel holder 1, absorbing the reaction forces, is pressed with the extension piston 11 against the abutment 12.
  • the piston pump with the cylinder 9 or piston 8 is actuated, so that the water, which is now biased to high pressure, is sprayed or sprayed via the water supply channel 14 and the water nozzle 13.
  • the movement of the chisel 2 in the chisel holder 1 can also be used for rotating the chisel in a manner not explained here.
