Cutting part for steeply inclined coal seam and steeply inclined coal seam coal mining machine with cutting part

The invention discloses a cutting part for a steeply inclined coal seam and a steeply inclined coal seam coal mining machine with the cutting part. Comprising a machine shell provided with a cutting motor, a transmission mechanism, a rocker arm, a roller and a lower cutting depth adjusting device, a rocker arm shell of the rocker arm is hinged to the machine shell. The two sides of the end, away from the machine shell, of the rocker arm are symmetrically connected with two rollers through rocker arm connecting shafts. And a small roller which is arranged along the length direction of the rocker arm shell and is as long as the lower part of the rocker arm shell is in transmission connection right below the rocker arm. And by arranging the small roller, coal below the rocker arm can be cleaned, and normal cutting of the rocker arm can be ensured, so that normal operation of coal mining is ensured, and the coal mining efficiency is ensured. The device has the technical advantages of being simple in structure and
