COAL-EXTRACTIVE DRUM COMBINE, METHOD FOR LOADING COAL ON CONVEYOR, DRUM EXECUTIVE TOOL OF CLEANING COMBINE, MECHANISM FOR HOISTING EXECUTIVE TOOL OF COMBINE, MECHANISM FOR INCREASING STABILITY OF COMBINE, FEEDING MECHANISM OF COMBINE Russian patent published in 2005 - IPC

Abstract RU 2244124 C2

FIELD: mining industry.

SUBSTANCE: combine has main body, drive, feeding mechanism and executive tool, which is made in form of drum with horizontal rotation axis. It is placed at non-straight angle to longitudinal conveyor axis and is turned in horizontal plane in direction providing for displacement of trajectory of coal output towards conveyor. Drum has cylinder, on outer surface of which in certain order cams with cutters are fixed. Inside the cylinder three or five electric engines are placed. These are inserted in parallel in recesses of fixed body with inner teeth of sun ring of planetary gear, which interact with three satellites. Output shafts of three or five electric engines interact with one common cog-wheel. It is placed coaxially with planetary gear and engaged with it by torsion shaft having two cog tail pieces. One of tail pieces interacts with inner slits of wheel hub, and another interacts with teeth of three satellites of planetary gear. Mechanism for hoisting drum mechanism along bed massive has handle raising jack and handle with horizontal rotation axis placed in horizontal plane at non-straight angle to conveyor axis and turned to direct displacement of executive tool towards pit-face. Shoes of stability mechanism for combine are provided with reverse clamps for shelves on front pit-face and back dump sides of conveyor. Back support of conveyor on soil is placed on dump end of inter-section beams. Combine feeding mechanism has drive for chainless feeding system and leading sprocket. Sprocket interacts with fingers of conveyor rack. Drive is placed beyond handle of executive tool and is made in form of separate electric engine with reducer of self-braking worm type. Engagement of sprocket with fingers is guaranteed by reverse clamp of reducer engaging back planes of conveyor rack carrying these fingers. In method for loading coal on conveyor, drum rotation axis in plane around vertical axis is turned in certain direction to turn trajectory of coal towards conveyor. Movement of mining drum along conveyor is performed first along ceiling, and then along soil along coal output direction while providing for cleaning of soil in direction of frontal movement of conveyor to pit-face.

EFFECT: lesser dimensions, lesser mass, higher quality of operation.
