DEVICE FOR MINING OF FERROMANGANESIAN CONCRETIONS Russian patent published in 2002 - IPC

FIELD: equipment for mining of ferromanganesian concretions. SUBSTANCE: device includes craft connected with submersible apparatus by means of pipeline. Submersible apparatus is made in form of body installed on running wheel pair and accommodating catching-and-crushing mechanism connected wit axle of running wheel pair. Device is distinguished by the fact that catching-and-crushing mechanism is made in form of cylindrical case with window on side surface and installed for rotation round immovable axle of running wheel pair and kinematically connected with air drive of reversive rotation. Crushing unit of catching-and-crushing mechanism is made in form of spiral spring rigidly connected with its one end to axle of running wheel pair, and with its other end, to edge of window of cylindrical case. Axle of driven wheel pair is hollow and has hole connecting axle hollow with hollow of cylindrical case, and by means of air lift rigidly connected with driven axle, is hydraulically connected with accumulating bin located in body of device and hydraulically connected with receiving hole of pipeline. Besides, device has lock mechanism, for instance, made in form of spring-loaded latch installed on device body for engagement with recess made on outer surface of case.
