PURPOSE:To simplify a device by branching off cutter head driving force through a gear, and driving a mixer in the opposite direction to the cutter head through branch driving force. CONSTITUTION:An idle gear 7 is so mounted that it is interlocked with a center gear 8 adjacent to a pinion 2 of a motor output shaft 1a, and the gear 8 is connected to a mixer driving shaft 10 through a key or a spline 9. After that, when a cutter motor 1 is operated, a cutter head 6 is driven through the pinion 2, an internal gear 3, an intermediate bearing ring 4 and an intermediate bearing arm 5. And at the same time, a mixer 11 is driven in the opposite direction to the cutter head 6 through the idle gear 7, the center gear 8 and the driving shaft 10. According to the constitution, a device can be simplified by sharing the driving force of the mixer 11 of excavated earth in a chamber and the cutter driving force. |
