CHAINLESS PROPULSION SYSTEM OF CUTTER-LOADER FOR FREEING MINERAL

The chainless propulsion system of a cutter-loader for freeing the mineral comprises a guiding rack (4) which is engaged with sprockets (7) being rotatably mounted on the cutter-loader. The sprockets (7) are kinematically connected with hydraulic cylinders (9, 10) through a rotatory mechanism (11) w...

Zusammenfassung:	The chainless propulsion system of a cutter-loader for freeing the mineral comprises a guiding rack (4) which is engaged with sprockets (7) being rotatably mounted on the cutter-loader. The sprockets (7) are kinematically connected with hydraulic cylinders (9, 10) through a rotatory mechanism (11) which causes the revolving motion along the rack (5). The rotatory mechanism (11) is provided with a carrier (12) having thereon a pusher (15) which is adapted for the engagement and the disengagement with the sprocket (7). To this effect the pusher (15) is articulated on the carrier (12) kinematically connected with the hydraulic cylinders (9, 10), which are arranged opposite to the pusher (15). Le système de propulsion sans chaîne d'une haveuse-chargeuse permettant de dégager le minerai comprend une barre à crémaillère de guidage s'engageant avec des dents de pignon (7) montées en rotation sur la haveuse-chargeuse. Les dents de pignon (7) sont reliées cinématiquement à des cylindres hydrauliques (9, 10) par l'intermédiaire d'un mécanisme de rotation (11) qui provoque le mouvement de rotation le long de la crémaillière (5). Le mécanisme de rotation (11) est pourvu d'un support (12) portant un poussoir (15) adapté pour s'engager et se dégager par rapport aux dents de pignon (7). A cet effet, le poussoir (15) est articulé sur le support (12) relié cinématiquement aux cylindres hydrauliques (9, 10) lesquels sont opposés au poussoir (15).
