CUTTING MACHINE CUTTER FOR MINERAL DEPOSITS AND SUCH Russian patent published in 2017 - IPC E21C35/187 E21C35/22 

FIELD: machine building.

SUBSTANCE: group of inventions relates to mineral deposits cutting machine cutter. In one embodiment cutting machine cutter assembly includes cutting machine cutter and cam. At that, cutting machine cutter comprises head, made with possibility to retain cutter, shank, extending in lengthwise direction from head, and heel, extending across longitudinal direction from head. Heel comprises first and second sides, separated by heel thickness, and through hole, passing through heel thickness. At that, through hole has inlet end on heel first side and outlet end on heel second side. Cam has opening, spraying nozzle and outer surface. Hole is made with possibility to receive shank and installation of cutting machine cutter into working position, when shank is received into hole. At that, spraying nozzle comprises inlet hole to receive water and outlet hole to discharge water from spraying nozzle. At that, spraying nozzle extends from cam outer surface and sets outlet hole outside of cam. At that, when cutting machine cutter is in working position pair of jaws extends from heel, from heel first side, wherein jaws of pair are arranged at distance from each other with formation of clearance gap between them, through hole is located between jaws, through hole inlet end is directed to clearance gap, spraying nozzle is located between jaws, outlet hole is located in clearance gap, hole is made with possibility of water spraying, released from nozzle via through hole, and cam outer surface is arranged adjoining to jaws and extends between jaws, outer surface and jaws form channel, extending to through hole inlet side, wherein channel is hydraulically communicated with ambient environment.

EFFECT: technical result is improvement of cutting machine cutter spraying system.
