【考案の詳細な説明】
１ 考案の目的
本考案は、チツプソーの刃部に関するものであ
る。[Detailed Description of the Invention] 1. Purpose of the Invention The present invention relates to the blade of a chipsaw.
従来、刈払機その他において使用されるチツプ
ソーの刃部については、刃部の回転方向側に設け
た段部に超硬チツプを接着するものであつたた
め、その取付け固定が困難であつたり使用中に脱
落したりの欠点があつた。また、実公昭34−
19389号にかかる考案もなされているが、これは
超硬チツプを垂直方向に設けた凹溝に埋設するよ
うにしたものであるから、その取付け固定や脱落
防止の欠点は除去されるとしても、回転刃として
の切刈効果の良さは期待することができない欠点
があつた。 Conventionally, the blades of tip saws used in brush cutters and other equipment have had carbide tips glued to the step provided on the rotational side of the blade, making it difficult to attach and secure the tips and causing problems during use. It had some defects such as falling off. Also, Jikko Sho 34-
No. 19389 has also been proposed, but this method involves embedding carbide chips in vertical grooves, so even though the disadvantages of fixing the chip and preventing it from falling off can be eliminated, As a rotary blade, it had the disadvantage that the cutting effect could not be expected to be as good.
そこで、本考案はこれらの欠点を一掃した新し
いチツプソーの刃部を提供することを目的とする
ものである。 Therefore, the object of the present invention is to provide a new tip saw blade that eliminates these drawbacks.
２ 考案の構成
本考案の構成を図面の実施例について説明す
る。2. Structure of the invention The structure of the invention will be explained with reference to the embodiments shown in the drawings.
１は円盤体で、この円盤体の周縁部には全体が
やや回転方向に傾斜している刃台部２…が形成さ
れている。３…はこの刃台部２の回転方向側にそ
の上端部からやや間隔をおいてその上端面と平行
の水平に設けた凹溝で、この凹溝の上方部は凸起
４…に成る。５…はこの円盤体１の刃台部２に構
成した凸起４および凹溝３に係合し熔接にて接着

前記刃台部２側の凸起４および凹溝３に対応する
凹部６と凸部７とがそれぞれ設けられている。ま
た、この超硬チツプ５の上端部と前側部とは、刃
台部２の上端部および前側部の外方に突出した状
態に成る。 Reference numeral 1 denotes a disc body, and a blade rest part 2 is formed on the peripheral edge of the disc body, the entire blade being slightly inclined in the direction of rotation. 3... is a groove provided horizontally on the rotational direction side of the blade rest 2 at a slight distance from the upper end thereof and parallel to the upper end surface thereof, and the upper part of this groove becomes a protrusion 4.... 5... is a carbide chip that engages with the protrusion 4 and the groove 3 formed on the blade rest part 2 of this disc body 1 and is bonded by welding. A concave portion 6 and a convex portion 7 corresponding to the convex portion 4 and the concave groove 3 on the second side are provided, respectively. Further, the upper end and front side of this carbide tip 5 are in a state of protruding outward from the upper end and front side of the blade rest 2.
第１図と第２図においては、形状のやや異なる
超硬チツプの例を示しているが、チツプ５が刃台
部２の水平方向に形成した凸起４と凹溝３にそれ
ぞれ係合する凹部６と凸部７を設けていることは
同じである。 1 and 2 show examples of carbide tips with slightly different shapes, but the tips 5 engage with the protrusions 4 and grooves 3 formed in the horizontal direction of the blade rest 2, respectively. It is the same that the concave portion 6 and the convex portion 7 are provided.
３ 考案の効果
本考案はこのように、円盤体１の各刃台部２の
回転方向側にその上端部から凸起４の間隔をおい

らず、しかもチツプは回転方向の上端部と前側部
に突出しているから、その切込み効果はきわめて
良く、常に良好な作業を行なうことができ、その
実用的効果は、大きいものである。3. Effects of the invention As described above, the present invention provides horizontal concave grooves 3 at intervals of protrusions 4 from the upper end on the rotation direction side of each blade rest part 2 of the disc body 1, and The recesses 6 and protrusions 7 which are engaged and fixed in the protrusions and grooves of the carbide chip 5
The carbide tip is provided on the rear side, and the upper end and front side of this carbide tip protrude outward from the upper end and front side of the blade rest. The base of the carbide tip attached to the rotational side of the blade base can be completely embraced and fixed, ensuring that the tip is supported and fixed, and the tip will remain stable even after long-term use. Since the tip does not fall off, and the tip protrudes toward the upper end and front side in the direction of rotation, the cutting effect is extremely good, and good work can be done at all times, and its practical effects are great. .
