Supply of liquid media for a hydraulic-mechanically operating mine working machine with sword

A mine apparatus for use with a longwall conveyor having a stowing side facing away from a longwall to be mined, comprising:

• a working machine (1) movable along a longwall (50) and having a sword (8) with a first part (10) carrying cutting tools to cut the longwall, and at least one second part (11) having a tractor hookup block (14) with a plurality of bores (15) therein for supplying high pressure liquid medium to said cutting tools for cutting and control purposes, said first and second parts being shaped to receive a longwall conveyor thereon and being connected to each other for relative movement therebetween;
• duct means defining separate upper and lower tractor ducts (3, 3') and a drag line duct (4) extending parallel to each other and at a stowing side of a longwall conveyor, said duct means including a slot (52) communicating said drag line duct with said lower tractor duct, said tractor hookup block being movable in said lower tractor duct;
• tractor means (13,25) movable in said lower tractor duct and connected to said tractor hookup block for pulling said tractor hookup block and said sword back and forth along the longwall;
• a hose hookup (7) which is separate from said tractor hookup block (14), fixedly connected to said tractor hookup block, said hose hookup block movable in said drag line duct (4) and extending through said slot for connection to said tractor hookup block, said hose hookup block having a plurality of bores (15) communicating respectively with said bores of said tractor hookup block;
• and
• a plurality of high pressure liquid media carrying lines (5) connected to said hose hookup block (7) and movable in and confined by said drag line duct for supplying high pressure liquid media to said bores and to said cutting tools for cutting and control purposes.
