DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a rotary pawl barrel which is mounted laterally on a transmission case, comprising: a sub-pawl barrel located at a lateral side of the transmission case; The present invention relates to a rotary tilling device configured to include a main claw shaft cylinder located at a portion and rotate the sub-claw shaft cylinder and the main claw shaft cylinder in directions opposite to each other.

[0002]

2. Description of the Related Art A rotary tilling claw shaft cylinder mounted laterally on a transmission case is composed of a sub-claw shaft cylinder located on the lateral side of the transmission case and a main claw shaft cylinder located on a lateral side of the transmission case in the axial center direction. The rotary tilling device is generally implemented as a center drive rotary tilling device of the residual cultivation method, but most conventional tilling devices always have the same downcut for both the main claw shaft cylinder and the subclaw shaft cylinder. It turned in the direction.

[0003] Therefore, when a traveling body provided with this kind of rotary tillage device is advanced and tilled, the driving reaction force of all the tilling claws mounted on the main claw shaft cylinder and the sub claw shaft cylinder promotes the body propulsion. When the field is relatively hard, the dash phenomenon of the airframe occurs, making it difficult for proper tilling to be performed, especially when the airframe is lightweight. There is a disadvantage.

[0004] For this reason, among the conventional ones, a main claw shaft cylinder and a sub claw shaft cylinder are rotated in opposite directions to each other, so that a tilling claw mounted on the main claw shaft cylinder and a tillage mounted on the sub-claw shaft cylinder. In some cases, the dash phenomenon of the fuselage has been suppressed by driving the claws into the ground in opposition to each other (for example, Japanese Patent Publication No. 46-390).
No. 41).

[0005]

However, the conventional one can only operate in such a form that the cultivating claw of the main claw shaft cylinder and the cultivating claw of the sub-claw shaft cylinder always rotate in the opposite direction and are driven into the soil. Therefore, for example, when performing soil cultivation work, there is an inconvenience that it is not possible to rotate all the tillage claws in the same direction to cope with them.

Accordingly, the present invention provides a rotary tilling apparatus capable of suppressing the dash phenomenon of an airframe by rotating a cultivating claw of a main claw shaft cylinder and a cultivating claw of a sub-claw shaft cylinder in opposite directions and driving them into the soil. However, the present invention provides a rotary tilling device that can rotate all the tilling claws in the same direction when necessary.

[0007]

That is, in the rotary tilling apparatus according to the present invention, a rotary pawl shaft tube horizontally mounted on a transmission case (7) is attached to an auxiliary pawl located at a lateral side of the transmission case (7). The shaft cylinder (14) and the main claw shaft cylinder (13) located on the lateral side of the auxiliary claw shaft cylinder ( 14) in the axial center direction.
