Description
【０００１】[0001]
この考案は、刈払機本体に装着して使用される回転刃の補助刃とその補助刃を 備えたカッタ−に関する。 とりわけ、刈払機の使用時に回転刃の取付部上面の周囲に巻きつこうとする草 木やつるなど（以下未切断の草木を用語「草類」、切断後の草木を用語「刈草」 と称する）単に刈草と称する）を切断することにより、刈草の巻きつきの防止を 図るようにする補助刃に関する。 This invention relates to an auxiliary blade of a rotary blade that is attached to a brush cutter main body and used, and a cutter equipped with the auxiliary blade. In particular, plants and vines that try to wrap around the upper surface of the rotary blade mounting part when using a brush cutter (hereinafter, uncut plants are referred to as "grass", and plants after cutting are referred to as "cut grass"). ) It is related to an auxiliary blade for preventing the cutting of the grass by simply cutting the grass.
【０００２】 この種の刈払機の通常の使用方法は、刈ろうとする未切断の草類の正面に作業 者が立ち、刈払機を駆動させることにより草刈り作業を行うことは広く知られて いる。It is widely known that a normal use method of this type of brush cutter is that an operator stands in front of the uncut grass to be mowed and drives the brush cutter to perform the mowing work.
【０００３】 この場合、刈払機の背面側には未切断の草類が繁っているから、切断された刈 草はその未切断の草類が障害となって、回転刃の取付部上面に巻きつこうとする 現象が発生する。In this case, since uncut grass grows on the back side of the brush cutter, the cut grass is obstructed by the uncut grass and is wound around the upper surface of the rotary blade mounting portion. The phenomenon of trying to occur occurs.
【０００４】 とりわけ、取付部の基部に対して回転刃は倒立略Ｔ字状に装着されることが普 通であるから、その基部には切断後の刈草が強く巻きつくことが回避できなっか た。In particular, since the rotary blade is usually mounted in an inverted T-shape with respect to the base of the mounting portion, it is difficult to avoid strong cutting grass being wrapped around the base. It was
【０００５】[0005]
そこで、前記の問題点を解消するため、取付部上面に回転刃本体の水平面に対 してシャ−レ型本体に補助刃を設けることにより、取付部上面に巻きつこうとす る刈草を切断しようとするものがある（実公平４−２４９０４号公報参照）。 Therefore, in order to solve the above-mentioned problems, an auxiliary blade is provided on the upper surface of the mounting portion against the horizontal surface of the rotary blade body to cut the grass to be wound around the upper surface of the mounting portion. There is something to be tried (see Japanese Utility Model Publication No. 4-24904).
【０００６】 しかし、この従来技術では、切断後の巻きつこうとする刈草はシャ−レ型本体 の側面直立部分にに沿ってそのまま上方に飛散し、二次的に切断されないまま、 取付部に巻き付くことが少なくなかった。However, in this conventional technique, the grass to be wound up after cutting is scattered upward as it is along the side surface upright portion of the dish type main body, and is not cut secondarily to the attachment portion. It was often wrapped around.
【０００７】 また、いわゆるコ−ドカッタについてはその解決手段が施されていないため、 駆動軸ケ−スの下部周囲に刈草が巻きつくことを回避できなかった（米国特許明 細書第４１４５８０９号明細書参照）。Further, since the so-called code cutter is not provided with a solution, it is impossible to prevent the cutting grass from being wound around the lower portion of the drive shaft case (US Pat. No. 4,145,809). reference).
【０００８】[0008]
この考案が解決しようとする問題点は、刈払機の回転刃の取付部上面側の周囲 やコ−ドカッタの駆動軸ケ−スの下部周囲に巻きつこうとする刈草を確実に切断 できない点である。 The problem to be solved by this invention is that it is not possible to reliably cut the grass to be wound around the upper surface of the rotary blade of the brush cutter or around the lower part of the drive shaft case of the cord cutter. is there.

【実施例１】 この考案の詳細を実施例１を示す図１ないし図３を参照して説明する。 図１は刈払機の取付軸に装着して使用されるいわゆる回転刃と併せ使用される 補助刃の平面図、第２図は図１の使用状態を示す側面図、第３図は図１のＡ−Ａ 線断面図である。First Embodiment The details of the present invention will be described with reference to FIGS. 1 to 3 showing a first embodiment. FIG. 1 is a plan view of an auxiliary blade used together with a so-called rotary blade mounted on a mounting shaft of a brush cutter, FIG. 2 is a side view showing the usage state of FIG. 1, and FIG. It is an AA line sectional view.
【００１３】 図２を参照して明らかなように、回転刃１０の径に比較して小さな径による円 盤状の補助刃本体が１２設けられ、この中心には回転刃１０の取付部１８のため の取付孔（図示を省略）と共通する取付孔１４が設けられている。 この補助刃本体１２は円形のものを図示したが、円形に制限されることなく、 方形、楕円形など形態を問わない。As is clear with reference to FIG. 2, a disk-shaped auxiliary blade body 12 having a diameter smaller than that of the rotary blade 10 is provided, and the mounting portion 18 of the rotary blade 10 is provided at the center thereof. A mounting hole 14 common to the mounting hole (not shown) is provided. Although the auxiliary blade main body 12 is shown as a circular one, it is not limited to a circular shape and may have any shape such as a square or an ellipse.
【００１４】 そして、前記した補助刃本体１２の外周縁には図１、図３を参照して明らかな とおり、外側に向けて傾斜した立ち上がり部１６が設けられている。As is apparent from FIGS. 1 and 3, a rising portion 16 inclined outward is provided on the outer peripheral edge of the auxiliary blade body 12 described above.
【００１５】 この立ち上がり部１６は、図２を参照して明らかなように、一側から他側に向 けて徐々にその高くなっているが、補助刃本体１２側が低く、補助刃本体１２か ら遠ざかるにしたがって高く設けられている。As is apparent from FIG. 2, the rising portion 16 gradually rises from one side to the other side, but the auxiliary blade body 12 side is low and the rising portion 16 is It is set higher as it moves away from it.
【００１６】 そして、この立ち上がり部１６には鋸刃２０が形成されている。A saw blade 20 is formed on the rising portion 16.
【００１７】 そこで、この実施例の使用方法を回転刃１０との組み合わせて説明する。 図２を参照して明らかなように、前記の構成による補助刃２２の取付孔１４を 刈払機本体２４の取付部１８に装着させる。Therefore, a method of using this embodiment will be described in combination with the rotary blade 10. As is apparent from FIG. 2, the mounting hole 14 of the auxiliary blade 22 having the above-described configuration is mounted on the mounting portion 18 of the brush cutter main body 24.
【００１８】 この場合、補助刃２２に設けられた鋸刃２０側を刈払機本体２４側に配置させ る。In this case, the saw blade 20 side provided on the auxiliary blade 22 is arranged on the brush cutter main body 24 side.
【００１９】 次いで、通常広く採用されている回転刃１０の取付孔を補助刃２２と共通な取 付部１８に装着させ、両者１０、２２を刈払機本体２４の駆動軸（図示せず）に ボルト等の固定手段１９を介して緊定させる（図２を参照）。Next, the mounting hole of the rotary blade 10, which is generally widely used, is attached to the mounting portion 18 common to the auxiliary blade 22, and the both 10 and 22 are attached to the drive shaft (not shown) of the brush cutter main body 24. It is tightened through fixing means 19 such as bolts (see FIG. 2).
【００２０】 そこで、両者１０、２２を結合させた状態の作用について説明すると、駆動源 により、補助刃２２は回転刃１０とともに回転させる。Therefore, the operation of the state in which the both 10 and 22 are combined will be described. The auxiliary blade 22 is rotated together with the rotary blade 10 by the drive source.
【００２１】 この状態で草類を切断すると、回転刃１０により草類は一次切断が確実に実施 されるものの、前記したように、回転刃１０により切断された刈草が倒れるよう にして刈払機本体２４の取付部１８の上面側に巻き込まれることが決して少なく ない。When the grass is cut in this state, the rotary blade 10 surely performs the primary cutting of the grass, but as described above, the grass cut by the rotary blade 10 is made to fall and the brush cutter main body is cut. It is not uncommon for 24 to be caught on the upper surface side of the mounting portion 18.
【００２２】 とりわけ、水平な回転刃１０に対して直立状に設けられた取付部１８の上面基 部には刈草が巻きつき易い。In particular, grass is likely to wind around the upper surface base of the mounting portion 18 provided upright with respect to the horizontal rotary blade 10.
【００２３】 ところが、この考案では、取付部１８の上面周囲に鋸刃２０が前記したように 外側に向けて傾斜されるとともに、その高さが徐々に高く設けられているから、 取付部１８の上面側に巻きつこうとする切断後の刈草は上方に飛散することなく 、その鋸刃２０に追従して二次切断が行われる。However, in this invention, the saw blade 20 is inclined outward as described above around the upper surface of the mounting portion 18, and the height thereof is gradually increased. The cut grass that is about to be wound on the upper surface side does not scatter upward and is secondarily cut by following the saw blade 20.
【００２４】 とりわけ、立ち上がり部１６に設けられた刃は平刃ではなく、鋸刃２０である から、硬質な茎などの刈草であっても刈草を捕捉するようにして切断できる。In particular, since the blade provided on the rising portion 16 is not the flat blade but the saw blade 20, even grass such as hard stalks can be cut by catching the grass.
【００２５】 このことは「平刃による鎌」の機能に対してこの考案はいわゆる「鋸切鎌」の 機能に等しいというべきである。This means that the present invention is equivalent to the function of a so-called “saw-toothed sickle” in contrast to the function of a “flat blade sickle”.
【００２６】 なお、この実施例１における補助刃２２の立ち上がり部１６は外側に傾斜して いるが、傾斜させることにのみ制限する趣旨ではなく、例えば略水平状から直立 状に到る任意の角度に設けることも考案者は予定している。Although the rising portion 16 of the auxiliary blade 22 in the first embodiment is inclined outward, it is not limited to the inclination, and for example, an arbitrary angle from a substantially horizontal shape to an upright shape can be obtained. The inventor also plans to install it in.
【００２７】 さらにいえば、補助刃本体１２の形状を問わないし、立ち上がり部１６の数に ついても制限しない。少なくとも鋸刃２０を備えた１個の立ち上がり部１６があ ればよい。Furthermore, the shape of the auxiliary blade body 12 is not limited, and the number of the rising portions 16 is not limited. It suffices if there is at least one rising portion 16 provided with the saw blade 20.
【００２８】 また、鋸刃２０の形状、曲げ角度等も任意に設定してよい。Further, the shape and bending angle of the saw blade 20 may be set arbitrarily.
【００２９】 さらにいえば、本考案の補助刃２２は１枚の板から製造できるから製造コスト 面から大いに経済的である。Furthermore, since the auxiliary blade 22 of the present invention can be manufactured from a single plate, it is very economical in terms of manufacturing cost.

【００３１】 この実施例は、刈払機本体の駆動軸ケ−ス２８（図６を参照）側に、外周寄り が内側から外側に向けて下方に傾斜したテ−パ面３０を有するコ−ドカッタと称 されていもののコ−ドカッタ用ケ−ス３２に適用される。In this embodiment, a cord cutter has a taper surface 30 on the drive shaft case 28 (see FIG. 6) side of the brush cutter main body, in which the outer peripheral side is inclined downward from the inside toward the outside. It is applied to the code cutter case 32 of the so-called.
【００３２】 補助刃３４の構成は、考案の本質において実施例１の補助刃２２と変化は少な いものの、多少の工夫が凝らしてある。The configuration of the auxiliary blade 34 is slightly different from the auxiliary blade 22 of the first embodiment in the essence of the invention, but some improvements are made.
【００３３】 コ−ド３８を収容するコ−ドカッタ用ケ−ス３２に設けられた取付孔（図示省 略）と共通な取付孔１４を備えた補助刃本体１２の外周縁に立ち上がり部１６が ２個設けられ、この立ち上がり部１６は補助刃本体１２側が低く、補助刃本体１ ２から遠ざかるにしたがって徐々に高く設けられている。A rising portion 16 is provided at the outer peripheral edge of the auxiliary blade main body 12 having a mounting hole 14 common to the mounting hole (not shown) provided in the code cutter case 32 for accommodating the code 38. Two rising portions 16 are provided on the side of the auxiliary blade main body 12 which is low, and is gradually increased as the distance from the auxiliary blade main body 12 increases.
【００３４】 この実施例では図５を参照して明らかなとおり、立ち上がり部１６は外側に向 けて傾斜しているが、必ずしも傾斜していることが必須ではなく略水平状から略 直立状に到る任意の角度に設けることも考案者は予定している。In this embodiment, as is apparent from FIG. 5, the rising portion 16 is inclined outward, but it is not always necessary to incline, and the rising portion 16 is changed from a substantially horizontal shape to a substantially upright shape. The inventor also plans to provide it at any arbitrary angle.
【００３５】 また、立ち上がり部１６の数は２個に制限されるものではなく、少なくとも１ 個設ければよい。Further, the number of the rising portions 16 is not limited to two, and at least one may be provided.
【００３６】 そして、前記した立ち上がり部１６には実施例１と同様に鋸刃２０が設けられ ている。A saw blade 20 is provided on the rising portion 16 as in the first embodiment.
【００３７】 補助刃本体１２の外周縁に前記したコ−ドカッタ用ケ−ス３２のテ−バ面３０ に対応された下向刃部３６が鋸刃２０と交差方向に２個設けられている。 もちろん、下向刃部３６を鋸刃２０と交差方向にのみ制限する趣旨ではない。On the outer peripheral edge of the auxiliary blade body 12, two downward blade portions 36 corresponding to the taper surface 30 of the code cutter case 32 are provided in the intersecting direction with the saw blade 20. . Of course, it does not mean that the downward blade portion 36 is limited only to the crossing direction of the saw blade 20.
【００３８】 刈払機本体の駆動軸ケ−ス２８内の駆動軸（図示せず）に補助刃３４が装着さ れ、さらに該駆動軸の下方にコ−ドカッタ用ケ−ス３２が装着されるが、この場 合、前記した補助刃３４の下向刃部３６がコ−ドカッタ用ケ−ス３２のテ−バ面 ３０に倣うように設けられている。An auxiliary blade 34 is attached to a drive shaft (not shown) in the drive shaft case 28 of the brush cutter main body, and a code cutter case 32 is attached below the drive shaft. In this case, however, the downward blade portion 36 of the auxiliary blade 34 is provided so as to follow the taper surface 30 of the cord cutter case 32.
【００３９】 そこで、この実施例の作用について説明すると、回転するコ−ド３８により草 類が一次切断されるが、取付部側に巻きつこうとする刈草のうち、コ−ドカッタ 用ケ−ス３２のテ−バ面３０側に飛散してくる刈草は、補助刃３４の下向刃部３ ６の刃４０によって二次切断され、さらに下向刃部３６の刃４０により捕捉、切 断の漏れによる刈草は駆動軸ケ−ス２８の下部側に向けて巻きつこうとするが、 この場合は補助刃３４の鋸刃２０に追従して三次切断されることにより巻きつく ことがない。The operation of this embodiment will now be described. Although the grass is primarily cut by the rotating cord 38, the case for the cord cutter out of the grass to be wound around the attachment portion side. The cutting grass scattered on the side of the taper surface 30 of 32 is secondarily cut by the blade 40 of the downward blade portion 36 of the auxiliary blade 34, and further captured and cut by the blade 40 of the downward blade portion 36. The grass cut due to the leakage tries to wind toward the lower side of the drive shaft case 28, but in this case, it does not wind up because it is tertiary cut following the saw blade 20 of the auxiliary blade 34.
【００４０】[0040]
この考案は、上記の構成であるから、以下の利点を奏する。 （１）立ち上がり部は補助刃本体側が低く、補助刃本体から遠ざかるにしたがっ て徐々に高く設けられ、その立ち上がり部には鋸刃が設けられているから、使用 に際して切断後の刈草は鋸刃に追従して確実に切断されるので、取付部側に巻き つくことを回避できる。 （２）補助刃と回転刃は互いに独立して構成されているから、交換使用が容易に できる。 （３）補助刃の外周寄りに下向刃部が設けられているから、コ−ドカッタについ て取付部に巻きつこうとする刈草をこの下向刃部と鋸刃と相待ってに切断できる ので駆動軸側に巻きつこうとする刈草の切断もまた可能である。 Since the present invention has the above-mentioned configuration, it has the following advantages. (1) The rising part is low on the auxiliary blade body side and gradually rises as it moves away from the auxiliary blade body. Since the rising part is provided with a saw blade, the cut grass after cutting is cut into a saw blade. Since it is followed and cut reliably, it is possible to avoid winding around the mounting portion side. (2) Since the auxiliary blade and the rotary blade are configured independently of each other, they can be easily replaced and used. (3) Since the downward blade part is provided near the outer periphery of the auxiliary blade, it is possible to cut the grass that is about to wind around the attachment part of the cord cutter while waiting for the downward blade part and the saw blade. Therefore, it is also possible to cut the grass that is going to be wound around the drive shaft.
