A new coal mining cutting device

Abstract

The utility model discloses a novel coal mining cutting device, including the cutting part for connecting coal winning machine and drum, the one end dismantlable connection of cutting part mounting drum has the deceleration part, and the transmission connection of drum is passed through deceleration part and cutting part, and the rotation axis of drum is along vertical direction setting, through cutting part and deceleration part mounting drum, and the rotation axis of drum is along vertical direction, can make cutting drum and coal wall keep perpendicular, and cut into coal body with perpendicular angle and carry out mining operation, compared with the oblique cutting knife mode of transmission, vertical knife mode has direct, simple operation characteristics, and the adjustment time is short at the end of working face, and it is favorable to the effective broken seam, and more accurate control coal mining depth, and vertical knife also help to reduce the resistance in the cutting process, reduce the equipment wear condition, thereby guarantee the quality and efficiency of coal mining operation, the deceleration part is dismantlable connection setting with cutting part, and the deceleration part is relatively independent and is convenient for dismounting maintenance.
