Axial-type cutting head having reduced drilling deviation and torque reaction force
An axial rotation type cutting head according to the present invention has an advantage that a drum is divided into two or more parts and each part is rotated in opposite directions, thereby reducing drilling deflection and deflection due to torque reaction force, generated during a shearing operation and a sumping operation. The axial rotation type cutting head of the present invention comprises a drum (11) and a pick cutter (7).
본 발명에 따른 축방향 회전식 커팅헤드는 드럼이 두 개 이상의 부분으로 분할되고 각 부분이 서로 반대방향으로 회전되므로 쉬어링 작업과 섬핑 작업시 발생하는 굴진 편향 및 토크 반력으로 인한 편향을 감소시킬 수 있다는 장점을 갖는다.
