COAL CUTTER-LOADER Russian patent published in 2009 - IPC E21C25/58 E21C27/00 

FIELD: mining.

SUBSTANCE: invention refers to mining industry and is designed for mechanized development of coal beds. The coal cutter-loader consists of feed mechanism, of a tool for intake of core with cutting elements secured on the end of the tool and projected to both sides from the wall of the tool, of a tool rotation mechanism with a drive asembled to travel lengthwise in a vertical plane and connected to the feed mechanism, and of a transporter. The coal cutter-loader is equipped with a base, an undercarriage with a drive, and mechanisms of lengthwise and transverse travel of the rotation mechanism relative to face, this rotation mechanism is connected to the tool, to a case for accumulating coal core, and to an offtake telescopic chute for supplying core to the transporter. Also the feed mechanism is made in form of a carriage connected to a drive by means of a lead screw; the carriage is mounted on a bed plate, which rests on a base. Mechanisms of lengthwise and transverse travel of the rotation mechanism relative to face are made in form of lead screws with drives, to which correspondingly the rotation mechanism and the feed mechanism carriage are connected. The rotation mechanism is installed to travel along guides assembled on the carriage by means of the mechanism of lengthwise travel relative to face; the mechanism of lengthwise travel is installed in its turn on the carriage. The case for core accumulating connected to the tool has a rectangular opening and is equipped with a driven swivel gate. Notably, the movable part of the offtake telescopic chute for supplying core to the transporter is attached to the said case opposite the said opening; the fixed part of the chute is secured on the carriage by means of a bracket.

EFFECT: increased efficiency of coal cutter-loaders and improvement of work environment in coal mines.
