耕耘爪
Document Type and Number:
Japanese Patent JP6827667
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a tilling claw in which the tilling resistance is reduced, the tillage speed can be made quick, and soil crushing properties and plowing-in performance are never lowered even if the tilling speed is increased.SOLUTION: A tilling claw is integrally formed of a mounting base 2, a vertical blade part 3, and a horizontal blade part 4 continuously curved from the vertical blade part 3 toward the reverse direction to the rotation direction and laterally curved. The tilling claw has a blade part 5 in the end edge side facing the rotary outer circumferential side. In the tilling claw, the blade part 5 is configured such that the blade width gradually becomes wider toward the horizontal blade part 4 from the vertical blade part 3 side and becomes the maximum width at the tip of the horizontal blade part 4, a curve beginning line 7 of the horizontal blade part 4 is inclined at the angle of 10 degrees to 15 degrees on the opposite side of the mounting base 2 to the mounting base central line 20, a curve height H to the tip of the horizontal blade part 4 is substantially the same as the size from a mounting base central line 20 to the curve beginning line position P of a blade part end edge 51 and the size of 1.7-1.9 times of a folding curvature radius r1, and a curve angle θ is the angle of 65 degrees to 75 degrees.SELECTED DRAWING: Figure 1
