MINING MACHINE WITH MOVING DISC CUTTERS (VERSIONS) Russian patent published in 2013 - IPC E21C25/16 

FIELD: mining.

SUBSTANCE: mining machine comprises a cutting mechanism, which comprises a cantilever, the first eccentrically rotated disc cutter installed on a cantilever and designed for interaction with a mined material and installed on the specified end of the cantilever, the specified end of the cantilever is rotated around the axis arranged at the angle to the specified longitudinal axis of the cantilever. The second eccentrically rotated disc cutter installed on the cantilever, arranged at the distance from the first disc cutter and designed for interaction with the mined material and installed at the specified end of the cantilever at the distance from the first disc cutter, the specified cutter is driven around the axis, which is parallel to the specified longitudinal axis of the cantilever. The third disc cutter designed for interaction with the mined material and installed on the specified end of the cantilever at the distance from the second disc cutter, the specified cutter is installed as capable of rotation around the axis arranged at the angle both to the specified longitudinal axis of the cantilever and to the axis of the first disc cutter. The platform, the support rod that connects the cantilever to the platform with the possibility of cantilever rotation relative to the platform, and a drive for rotation of the specified cantilever from side to side. Three disc cutters have an axis of cutting, which, passing through all three cutters, is perpendicular to the longitudinal axis of the cantilever and is diverted from the perpendicular line to the mine floor. Cutters cut the mined material for equal depth. The first disc cutter is in the lowest position and is arranged so that it contacts with the mined rock first, before other disc cutters. As the cantilever rotates to the mined rock, each of three disc cutters contacts with the rock at the angle of attack, formed between the cutting edge and the mined rock, besides, the angle of attack for all three disc cutters makes 10 degrees.

EFFECT: higher efficiency of mining machine operation.
