Description of the Related Art Rotating tillers include a down-cut type in which a plowing pawl is turned in the direction of travel of the machine body to rotate from the front to the rear, and a rotary plowing device is rotated in the direction of travel of the machine from the back to the front. There is an upcut type, but in the downcut type, the driving load of the tilling claw acts in a direction that promotes the propulsion of the aircraft, so the dash phenomenon of the aircraft easily occurs, and in the upcut type, Since the reaction force of the plowing claws works in the direction to suppress the airframe propulsion, the wheel slip phenomenon easily occurs, and proper plowing tends to be difficult in any case.

った。In the device of this type, the left and right main tillage claw shaft cylinders are directly mounted on the tiller shaft driven by the chain transmission mechanism in the central transmission case. The sub-cultivating pawl shaft cylinder, which is rotationally driven in the same direction as that of the main transmission case and is provided at the right and left side adjacent portions of the central transmission case, is a sub-pawl shaft drive mechanism using a sprocket meshing with the chain of the chain transmission mechanism as an input portion. In the conventional device, the sprocket, which is the input part of the sub-claw shaft drive mechanism, is installed on the tension side of the chain of the chain transmission mechanism. Since it was meshed, the chain winding angle was small,
If the chain pulsates due to the impact load of the plowing nail group that is fixed to the main tillage claw barrel and the sub tillage claw barrel due to the impact load, the transmission of the driving force to the sprocket becomes unstable and the rotation of the sub tillage claw barrel occurs. There is a problem that the driving is not performed stably.

The shaft drive mechanism is used to drive the sub-cultivating claw shaft cylinder to rotate. Then, the sprocket, which is the input part of the sub-claw shaft drive mechanism, meshes with the slack side of the chain of the chain transmission mechanism to increase the chain winding angle, and the plowing claws of the main and sub-cultivating claw shaft cylinders. Even if the chain pulsates due to the impact load due to driving into the soil, the driving force transmission to the sprocket does not become unstable, and the sub-tiling claw shaft cylinder is rotationally driven constantly.
