Control of the pressure water of internally sprayed cutting drums

摘要

The invention relates to a spraying device for internally sprayed cutting drums, in particular for mining and heading machines. The spraying device specifically serves to apply pressure water to the cutting picks in engagement. Pressure water passes via a bore (7) in the fixed shearing drum spindle (8) into an annular distribution passage (15) from which branch passages (16) lead to valve units (19). These valve units (19) are activated axially via the end face (29) of the planetary-gearing flange (26). The end face (29) is inclined relative to the shearing drum spindle (8). <IMAGE>
