Central lubrication device for underground mining machine - couples all lubrication lines via distributor to hydraulically-operated grease gun

摘要

The lubrication device has lubrication lines (1..5) leading to the individual lubrication points, coupled at the lubrication station to a distributor (6) supplied via a grease ejection gun (7) having a driven ejection piston (8). The latter is operated via a hydraulic cylinder (11), with its piston (12) coupled to the grease gun piston via a piston rod (13). Pref. the hydraulic cylinder is supplied via a magnetic valve (18) with a common control device (20) coupled to the latter and to the distributor. ADVANTAGE - Allows simple replacement of grease cartridge.
