According to the device of the present invention, the rotary pawl shaft tube provided laterally on the transmission case (7) is provided with the auxiliary pawl shaft tube (14) located at the side of the transmission case (7). ) And a main claw shaft cylinder (13) located on the lateral side of the auxiliary claw shaft cylinder (14) in the axial center direction, and these sub claw shaft cylinder (14) and main claw shaft cylinder (13) are divided. ) and the, driving secondary pawl shaft barrel
Claw barrel drive comprising a dynamic system (17) and a main claw barrel drive system (11)
In a rotary tilling device rotated in opposite directions by a moving mechanism, the two claw shafts are provided in the claw shaft driving mechanism.
Switch to transmission position to rotate cylinders (13) and (14) in the same direction
And characterized in that a rotation direction switching means (25) for obtaining
Therefore, the tilling claw (16) of the auxiliary claw shaft cylinder (14) and the cultivating claw (1) of the main claw shaft cylinder (13) rotating in opposite directions to each other.
5) While the tilling work can be performed while suppressing the dash phenomenon of the fuselage by driving into the soil in the opposite direction of 5), if necessary, the tilling claw (16) of the sub-claw shaft cylinder (14) and the main claw can be used. It is also possible to perform tilling work by rotating the tilling claws (15) of the shaft cylinder (13) together in the same direction, and this is a rotary tilling apparatus that is widely adaptable to the work to be performed and to differences in the field environment and the like.
