[Prior art 1] Tillage claws for cultivating soil have been conventionally used, for example, in Japanese Unexamined Utility Model Publication No. 58-55402 and Japanese Unexamined Utility Model Publication No. 58-50-ii33.
As disclosed in Publication No. 01, etc., it is a tilling claw that has a mounting base, a vertical blade, and a horizontal force part, and is curved to one side from the vertical blade to the horizontal blade, and has a vertical blade. It is known that the blade is twisted from the blade to the side blade, or that the side blade is curved into an arc in the width direction. [Problems to be Solved by the Invention] However, in the above-mentioned conventional tilling claws, when the twisted portion or the curved portion in an arc shape is driven into the top, the tilling resistance becomes large and the required power is reduced. As the area becomes larger, imaging tends to occur, which has the disadvantage of having an adverse effect on the rotary tiller and the tractor.

[Function 1] With the above structure, the tilling claws of the present invention have low plowing resistance, require less horsepower, and also have less movement when driven into the soil. [Example] Hereinafter, an example of the present invention will be specifically described with reference to the drawings. The IAI claw 1 continuously includes a mounting base 2 having a mounting hole 3, a vertical blade part 4, and a horizontal blade part 5. The length from the vertical blade part 4 to the horizontal blade part 5 is curved to one side with a substantially constant curvature, and a single-edged blade edge 6 is formed on the outer periphery of the vertical blade part 4 to the horizontal blade part 5. At the tip of the horizontal blade part 5, a warped part 7 is formed, which is slightly warped in the direction opposite to the musical direction from the vertical blade part 4 to the horizontal blade part 5, and has a slight suction angle θ. In addition, the blade edge 6 of the tilling claw 1 is curved in the length direction with a curved line that has good drainage properties, and is formed in a shape similar to a high skew propeller of a ship, with a rounded tip portion as a whole. There is. In the tilling claw 1 having such a configuration, for example, when it is attached to a rotary tiller and driven into the soil, the vertical blade portion 4
Since it is only curved to one side with a substantially constant curvature from the side blade part 5 to the horizontal blade part 5, the driving resistance and the resistance to pass through the soil are small, and the vibration is also small, reducing the tilling resistance and therefore the required horsepower. At the same time, there is no adverse effect on the rotary tiller or the tractor. In addition, the shape of the blade edge 6 and the shape of the tip are rounded, which has good tangle removal properties, prevents straw culms, etc. from wrapping around, and makes it easier to plow straw culms, etc. into the soil. It will be done. Furthermore, since it has the curved portion 7, soil drainage is good, soil adhesion to the nails is reduced, and overall efficient soil plowing work is performed. In addition, the bending line position and suction angle θ of the warped portion 7
is not limited to the above-mentioned embodiment, and may be at other positions and bending angles. [Effects of the Invention] As explained above, according to the tilling claw of the present invention, since the length from the vertical blade portion 4 to the horizontal blade portion 5 is only curved to one side with a substantially constant curvature, the tilling resistance is small and the required amount is reduced. Horsepower can be reduced, vibration is small, and there is no adverse effect on the rotary tiller or tractor. In addition, a curved portion 7 that curves slightly toward the opposite side is formed at the tip of the horizontal blade portion 5 to form a slight suction angle, allowing for good soil drainage.
There is less soil adhesion to the tiller claws, making it possible to perform soil cultivation and plowing operations with good overall efficiency.
