ど、種々の問題があつた。 In recent years, the advantages of the up-cut tilling method have been reviewed in rotary tilling devices, and rotary tillers that can be used for both the down-cut tilling method and the up-cut tilling method are now on the market. One type of tillage device is a rotary tiller shaft that can be rotated forward and backward, with a tiller claw that can be used for both forward and reverse rotation.
In the case of this device, due to the structure in which the tilling claws are used for both forward and reverse operations, for example, there is a large loss of material in the structure of the tilling claws themselves, and during tilling work, the original performance of down-cut tillage and up-cut tillage cannot be achieved. Furthermore, there were various problems such as increased tilling torque.

The tilling claw has a long horseshoe-shaped planar shape, has two opposing free ends as mounting bases, forms a pair of vertical blades that extend continuously in a straight line from the mounting base, and has two vertical blades at the tips of both vertical blades. The arc part that connects the parts in an arc shape is curved to one side to form a horizontal blade, and blade edges are formed on both sides from the vertical blade part to the horizontal blade. It is rotatably pivoted to a flange provided on the outer periphery of the tilling shaft perpendicular to the axis of the shaft, and the other mounting base is locked so as to be movable within a predetermined length range along the flange. This is a characteristic feature.

向上した正逆転耕耘作業を行うことができる。 As explained above, according to the forward and reverse rotary tilling device of the present invention, the tilling claws 1 are formed in a long horseshoe shape in plan view, and are continuously connected from the opposing mounting bases 2, 2 to the vertical blade parts 4, 4, and this vertical blade part 4,
Since the circular arc portion connecting the tips of 4 is the horizontal blade 5, and the blade edge 6 is formed from the vertical blade portions 4, 4 to the horizontal blade 5, it is possible to manufacture from one flat bar without loss. can. Further, one side of the mounting base 2 of the tilling claw 1 is attached to a flange 9 provided on the tilling shaft 8.
Since the other side of the mounting base 2 is slidably locked in the long hole 11, the tilling claws 1 can be rotated around the pivot hole 10 by forward and reverse rotation of the tilling shaft 8. It can be used as it is for either forward rotation (down cut) or reverse rotation (up cut) by moving within the length range of the slotted hole 11, and the tilling torque is almost the same in both forward and reverse rotations, making it easy to operate. It is possible to perform forward and reverse tillage work with improved performance.
