WORKING ROCK-CUTTING TOOL Russian patent published in 1995 - IPC

FIELD: mineral mining. SUBSTANCE: working rock-cutting tool has load-carrying metalwork on which carrier and supports are installed. Installed on carrier and supports are planetary rotating axles kinematically connected with each other and with carrier. Secured to axles are disks having rock cutting members. Axles are parallel to axis of carrier which is hinged to metalwork. Supports of different planetary axles are spaced along carrier axis. Rock cutting members are secured to knuckles installed on disks by means of flexible joints. Rock cutting members may be attached to knuckles in groups consisting of rock-cutting members successively arranged one after another, where every subsequent one is installed above the preceding one. Installed on load-carrying metalwork may be several carriers with disks and rock cutting members. In this event, carriers should be shifted relative to each other so that their cutting zones overlap each other, neighboring carriers are rotating in opposite directions. EFFECT: higher efficiency. 3 cl, 5 dwg
