本発明は、耕耘機の回転軸に固着して地表面を堀り起す
ための耕耘刃の製造方法に係るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a tiller blade that is fixed to the rotating shaft of a tiller and used to dig up the ground surface.
一般に、耕耘機においては、進行方向に対して直交する
方向に水平に設けられた回転軸に、多数の耕耘刃を固着
して地表面を堀り起す作業を行なっている。Generally, in a tiller, a large number of tilling blades are fixed to a rotating shaft provided horizontally in a direction perpendicular to the direction of travel, and the work of digging up the ground surface is carried out.
従来、この耕耘刃は鋼板で製作され、焼入処理により硬
化して使用しているが、土砂を掘削するために刃先部の
摩耗が激しく、耕耘刃を交換する頻度が高く、保守が厄
介で高価となっていた。Conventionally, this tilling blade is made of steel plate and hardened by quenching before use, but the blade tip is subject to severe wear as it excavates earth and sand, and the tilling blade has to be replaced frequently, making maintenance difficult. It was expensive.
また刃先部の一面に超硬質の金属材料を溶射、溶着する
方法も考えられるが、母材を耕耘刃形状に湾曲形成して
から溶着せしめるために、母材の曲り部では溶着材が流
れて溶着厚みが薄くなり、刃先部の溶着材の厚みが不均
衡となり、また使用中溶着材が剥離する恐れがあるもの
である。Another option is to thermally spray and weld an ultra-hard metal material onto one surface of the cutting edge, but since the base material is curved into the shape of a tiller blade and then welded, the welding material may flow around the curved part of the base material. The welding thickness becomes thinner, the thickness of the welding material at the cutting edge becomes unbalanced, and there is a risk that the welding material may peel off during use.
逆に、母材に超硬質の金属材料を溶着してから母材を湾
曲形成すると、超硬質の金属材料が亀裂を生じたり剥離
する恐れがある。On the other hand, if an ultra-hard metal material is welded to a base material and then the base material is curved, the ultra-hard metal material may crack or peel.
本発明は、刃先部の表面に、刃先縁との交差する方向に
設けた溝部を多数並設し、この溝部内に超硬質の硬質部
材を埋設することにより、上記欠点をなくして耐久性の
ある強度大なる耕耘刃を安価に得ることのできる耕耘刃
の製造方法を提供するものである。The present invention eliminates the above-mentioned drawbacks and improves durability by providing a large number of grooves in parallel on the surface of the cutting edge in a direction that intersects with the cutting edge, and by embedding an ultra-hard hard member in these grooves. To provide a method for manufacturing a tiller blade that can obtain a tiller blade with a certain degree of strength at a low cost.
