【考案の詳細な説明】
本考案は畦、土手、溝等の雑草、山林の下刈り
や笹刈りなどを行なうために用いられる第１図に
示すような刈払機Ａに用いる刈刃であつて円板状
の鋸身の周縁にタングステンカーバイトチツプな
どのチツプを取付けたチツプソーに関する考案で
ある。[Detailed Description of the Invention] The present invention is a cutting blade for use in a brush cutter A as shown in Fig. 1, which is used for cutting weeds in ridges, banks, ditches, etc., undergrowth in mountain forests, cutting bamboo grass, etc. This invention relates to a tip saw in which a tip such as a tungsten carbide tip is attached to the periphery of a disc-shaped saw blade.
従来のチツプソーは第５図、第６図に示すよう
に、鋸身１の厚みＴよりも大きな厚みt′のチツプ
３′を鋸身の周縁部にろう付けされているのが常
である。 As shown in FIGS. 5 and 6, conventional tip saws usually have a tip 3' having a thickness t' greater than the thickness T of the saw blade 1 and brazed to the peripheral edge of the saw blade.
また、その先端は鋸身１の外周縁１′よりも突
出して形成されている。 Further, its tip is formed to protrude beyond the outer peripheral edge 1' of the saw blade 1.
ところで、刈払機の性質上、使用中に刈刃が石
礫等被切物以外のものに当たる可能性が極めて高
い。従つて、従来のチツプソーでは鋸身１の表面
よりもチツプ３′が突出しているため、石礫等が
直接チツプに当たり、チツピングを起こしたり、
割れたりして破損する欠点があつた。 By the way, due to the nature of the brush cutter, there is a very high possibility that the cutting blade will hit something other than the object to be cut, such as stones and gravel, during use. Therefore, in a conventional chip saw, the chip 3' protrudes beyond the surface of the saw blade 1, so stones, etc. may directly hit the chip, causing chipping.
It had the disadvantage of cracking and breaking.
そこで、本考案はチツプの厚みを鋸身の厚みよ
り薄くすることによつて上記欠点を解消するよう
にしたものである。 Therefore, the present invention solves the above-mentioned drawbacks by making the thickness of the tip thinner than the thickness of the saw blade.
以下、本考案の実施例を添付の図面に基づいて
説明する。 Embodiments of the present invention will be described below with reference to the accompanying drawings.
第２図、第３図は本考案に係る刈払機用チツプ
ソーの平面図であつて、円板状の鋸身１の周縁部
に多数のガレツト２，２を多数形成し、ガレツト
部２，２間の突出部にチツプ３，３をろう付し、
切断刃４を形成してある。 2 and 3 are plan views of a tip saw for a brush cutter according to the present invention, in which a large number of gullets 2, 2 are formed on the peripheral edge of a disc-shaped saw blade 1. Braze chips 3, 3 to the protruding part between them,
A cutting blade 4 is formed.
そして、第４図に示すようにチツプ３の厚みｔ
は鋸身１の厚みＴよりも薄くし、かつ表裏いづれ
かの表面からも突出しないようにしてある。 Then, as shown in FIG. 4, the thickness t of the chip 3 is
is made thinner than the thickness T of the saw blade 1, and is made so as not to protrude from either the front or back surface.
即ち、チツプ３をろう付するにはチツプを取付
けるべき鋸身の一部を切除し段部５を形成し該段
部５にチツプ３をろう付けする。 That is, in order to braze the tip 3, a part of the saw blade to which the tip is to be attached is cut out to form a stepped portion 5, and the tip 3 is brazed to the stepped portion 5.
そして、チツプ３の先端３ａ（天刃）は鋸身１
の外周縁１′と面一に研磨し、少なくとも鋸身１
の回転軌跡からチツプの先端が突出しないように
しておくとよい。 The tip 3a (top blade) of tip 3 is the saw blade 1.
Grind it flush with the outer peripheral edge 1' of the saw blade, and at least
It is best to prevent the tip of the tip from protruding from the rotation locus.
第１図に示すように、チツプソーを刈払機Ａに
装着して使用する時、雑草等はまずガレツト２内
に入り込み、これが切刃であるチツプ３によつて
切断される。 As shown in FIG. 1, when a chip saw is attached to a brush cutter A and used, weeds and the like first enter the gullet 2 and are cut by the chip 3, which is a cutting blade.
本考案チツプソーによれば、刈刃であるチツプ
ソーを地面に接触させたり、小石に当てるような
ことがあつても、これが鋸身１のいづれかの部
分、主に外周縁近傍に当たり、チツプ３には直接
当たるようなことがなく、チツプを破損するよう
なことがない。 According to the chipsaw of the present invention, even if the cutting blade (chipsaw) comes into contact with the ground or hits a pebble, this will hit any part of the saw blade 1, mainly near the outer periphery, and the chip 3 will not be affected. There is no direct contact and no damage to the chip.
なお、チツプ３の先端（天刃）は鋸身１の外周
縁１′より多少突出していても従来のチツプソー
に比較すると直接地面に当てることは少ないが、
実施例のように外周縁から突出しないようにして
おけば、より効果的である。 Although the tip of the tip 3 (top blade) protrudes somewhat from the outer edge 1' of the saw blade 1, it is less likely to hit the ground directly compared to a conventional tip saw.
It will be more effective if it is prevented from protruding from the outer periphery as in the embodiment.
また、本考案では、チツプが被切断物以外のも
のに当てる可能性を可及的に少なくした結果チツ
プ３として、多少衝撃にはもろくても、より高硬
度の切れ味の鋭いものを採用することができ、チ
ツプソーの切味、寿命を著しく改善することがで
きる実益がある。 In addition, in this invention, as a result of reducing the possibility of the tip hitting something other than the object to be cut as much as possible, a tip with higher hardness and sharpness is used as the tip 3 even though it is somewhat brittle against impact. This has the practical benefit of significantly improving the sharpness and lifespan of the chipsaw.
