次に、耕うん爪３を爪ホルダ２から取外すときは、反対
方向にこれを叩くと、容易に取外せる。In addition, the biting state at the beginning of clamping is improved, and when a force is applied to the plow 3, the lateral force due to the wedge effect is reduced.
To prevent the claw holder 2 from being damaged, first, the first inclined surfaces 23, 24,
If the second inclined surface is moved to the second inclined surface 12, 13, 14, 15 with the next load, the second inclined surface has a larger inclination angle than the first inclined surface. The effect can be obtained.
Next, when removing the tillage claw 3 from the claw holder 2, it can be easily removed by hitting it in the opposite direction.
なお、この考案は、上記実施例に限定されるものでは
ない。例えば、爪ホルダ２の嵌合孔29に設ける傾斜面を
多角をもった傾斜面などによって形成することもでき
る。The present invention is not limited to the above embodiment. For example, the inclined surface provided in the fitting hole 29 of the claw holder 2 may be formed by an inclined surface having a polygon.
また、逆に第１傾斜面を省略し、屈曲形逃がし部の両
端e,e1から第２傾斜面を形成するようにしてもよい。Further, the first inclined surface is omitted Conversely, both ends e of the bent form the escaping portion may be from e 1 to form a second inclined surface.
更に、逃がし部6,7は屈曲形でなく半円などの円形で
もよい。Further, the relief portions 6 and 7 may be not a bent shape but a circular shape such as a semicircle.
