A fitting hole 1 is formed to fit the claw holder 3 and the held portion 7.
1 and the fitted side that fits into the fitting hole 11 are formed into a shape having a curved surface corresponding to the holder 7, thereby forming a support means for the tilling claw.
(ホ) 実施例
以下、この考案の実施例を図面に基づいて詳細
に説明する。(E) Embodiments Hereinafter, embodiments of this invention will be described in detail based on the drawings.
第１図はこの考案による耕耘爪の支持手段を示

る。 First, to explain the configuration, similarly to the latter conventional example described above, a large number of claw holders 3 are arranged on the outer peripheral surface of the tilling shaft 1 by means such as welding at appropriate intervals so as to form a radial shape when viewed from the side. It is fixed.
前記爪ホルダー３は、全体が一体の素材をもつ

に形成されている。そして、この爪ホルダー３の
ホルダー孔１１は、中間高さの左右対称位置に穿
設されたピン孔１３を境にしてＳ字形の平行曲面
１５，１７に形成されている。 The claw holder 3 is entirely made of a single piece of material and has an S-shaped cross section curved in the axial direction of the tilling shaft 1. The holder hole 11 of the claw holder 3 is formed into S-shaped parallel curved surfaces 15 and 17 with a pin hole 13 bored at a symmetrical position at an intermediate height as a boundary.
また、前記ホルダー孔１１内に着脱自在に嵌挿
する耕耘爪５は、被ホルダー部７と刃部１９（図
面では一部省略）とから構成されている。 Further, the tilling claw 5 which is removably inserted into the holder hole 11 is composed of a holder portion 7 and a blade portion 19 (partly omitted in the drawing).
前記被ホルダー部７は、爪ホルダー３のホルダ
ー孔１１と対応した曲面を有するＳ字形の平行曲
面２１，２３に形成されている。 The held portion 7 is formed into S-shaped parallel curved surfaces 21 and 23 having curved surfaces corresponding to the holder holes 11 of the nail holder 3.

によつて抜け止めがなされている。 Then, the held part 7 of the tilling claw 5 is fitted into the holder hole 11 of the claw holder 3, and the pin is fixed in the pin hole 13 of the claw holder 3 and the pin hole 25 of the held part 7 of the tilling claw 5. 9 is inserted, thereby fixing the tilling claws 5 to the claw holder 3 in a detachable manner. Note that the stop pin 9 is prevented from coming off by a split pin or the like (not shown).

かつ確実に支持することができる。 Next, to explain the operation using the above configuration, the tilling shaft 1 is rotated by the drive of the tilling device,
As a result, when the tilling claw 5 starts tilling the soil, the tilling claw 5 causes the held part 7 to move against the claw holder 3 by the reaction force of the soil tillage through the blade part 19. The parallel curved surface 21 of the lower part of the held part 7 rotates relative to the claw holder 3.
The upper part of the held part 7 is pressed against the parallel curved surface 15 on the rear side a of the claw holder 3, and conversely, the parallel curved surface 23 of the held part 7 is pressed against the parallel curved surface 17 on the front side b of the claw holder 3, so that it is supported under pressure. . In addition, the parallel curved surface 1 of the holder hole 11 is
5 and 17 elastically expand in the axial direction of the stop pin 9. Further, when the pressure of the reaction force disappears, the side wall of the holder hole 11 returns to its original state. Therefore, the side wall of the holder hole 11 has an elastic buffering property and also has a tightening action due to the elastic force. As a result, the held portion 7 can be firmly and reliably supported on the claw holder 3 without the need for fasteners such as bolts and nuts.
