Description

本発明は、小型エンジンを搭載する肩掛式刈払機，背負式刈払機と異なり、中型エンジンを搭載して車輪により走行する形式の車輪付き刈払機に関するものである。   The present invention relates to a wheeled brush cutter of a type that is mounted on a medium-sized engine and travels by wheels, unlike a shoulder-type brush cutter and a backpack-type brush cutter mounted with a small engine.

従来のこの種の車輪付き刈払機は、車輪の軸受部とこれより前後方に分かれて位置する刈刃保持部及びハンドル部とで構成される刈払機本体が前記車輪により走行するようになっている。   In this type of conventional brush cutter with wheels, a brush cutter main body composed of a wheel bearing portion and a cutting blade holding portion and a handle portion that are separated from the front and rear of the wheel is driven by the wheel. Yes.

解決しようとする問題は、従来のものでは車輪が刈払機本体に固定式に取り付けられているので、刈刃保持部の刈刃は車輪の前後進に合わせて平行移動する。そのために作業面（走行面）の凹凸に合わせて刈刃が振られる（左右に傾く）ために作業面に沿って平行に刈れないし、また作業面の勾配変化に対して刈刃の角度を変更できないために勾配のある作業面に沿って平行に刈れないし、さらに作業面に対して刈刃を擦るような高さにできないためにきわ刈り作業ができないという点である。   The problem to be solved is that the wheel is fixedly attached to the main body of the brush cutter in the conventional device, so that the cutting blade of the cutting blade holding portion moves in parallel with the forward and backward movement of the wheel. For this reason, the cutting blade is swung (tilted to the left and right) according to the unevenness of the work surface (running surface), so it cannot be cut in parallel along the work surface, and the angle of the cutting blade is changed with respect to the change in the gradient of the work surface. Since it cannot be done, it cannot be cut in parallel along the work surface with a gradient, and furthermore, it cannot be cut so high that the cutting blade cannot be rubbed against the work surface.

請求項１の発明は、複数の車輪と、当該複数の車輪の各車軸を支持する軸受シャーシと、当該軸受シャーシに左右首振り用縦軸により左右に回転可能に取り付けたシャーシと、当該シャーシに取り付けられ、且つ刈刃保持部を先端に取り付けた駆動パイプと、前端を当該駆動パイプに直接又は前記シャーシを介して一体的に取り付け、且つ後端にハンドル部を有するハンドルパイプとを備えてなり、前記車輪により走行するものであって、前記駆動パイプ及び前記ハンドルパイプと、前記軸受シャーシ及び前記車輪とが前記シャーシの位置で互いに前後方向の水平軸回りに左右に傾くようにして、前記刈刃保持部の刈刃に対して前記軸受シャーシ及び前記車輪が前後方向の水平軸回りに左右に傾くとともにハンドル部を左右に傾けると前記刈刃が前記軸受シャーシ及び前記車輪に対して左右に傾くようにし、さらに、前記駆動パイプの基端に取り付けたエンジンを備え、前記シャーシを前記駆動パイプのうち基端よりも前方に寄った位置に取り付けるとともに前記軸受シャーシが前記シャーシを介して前記駆動パイプを吊り下げて支持していることを特徴とする。 The invention of claim 1 includes a plurality of wheels, a bearing chassis that supports the axles of the plurality of wheels, a chassis that is attached to the bearing chassis so as to be rotatable left and right by a vertical axis for swinging left and right, and the chassis. And a driving pipe having a cutting blade holding part attached to the tip, and a handle pipe having a front end attached directly to the driving pipe directly or via the chassis and having a handle part at the rear end. The drive pipe and the handle pipe, and the bearing chassis and the wheel are inclined to the left and right around the horizontal axis in the front-rear direction at the position of the chassis. wherein said bearing chassis and the wheel relative to the cutting blade of the cutter holder tilts the handle portion to the left and right with inclined to the left and right about a horizontal axis in the longitudinal direction harvest There so inclined to the left and right with respect to the bearing chassis and the wheels, further comprising an engine mounted to the proximal end of the drive pipe, attaching said chassis to a position closer to the front than the base end of the drive pipe The bearing chassis suspends and supports the drive pipe through the chassis .

請求項２の発明は、前記左右首振り用縦軸を回転中心として前記駆動パイプ及び前記ハンドルパイプを前後で左右に振ることにより、刈刃保持部の刈刃を車輪よりも外側に出して固定できるようにしたことを特徴とする。 According to the second aspect of the present invention, the cutting blade of the cutting blade holding part is fixed outside the wheel by swinging the drive pipe and the handle pipe back and forth around the vertical axis for swinging the left and right. It is possible to do it.

請求項１の発明は、ハンドル部を真っ直ぐに保っていると作業面の凹凸に対して車輪側が左右に傾くので、刈刃保持部の刈刃を作業面に平行に保つことができて作業面に沿って平行に刈れるし、また作業面の勾配変化に対しても刈刃の角度を変更できて勾配のある作業面に沿って平行に刈れるし、さらに作業面に対して刈刃を擦るような高さにできてきわ刈り作業ができるという効果がある。 According to the first aspect of the present invention, when the handle portion is kept straight, the wheel side is inclined to the left and right with respect to the unevenness of the work surface. Therefore, the cutting blade of the cutting blade holding portion can be kept parallel to the work surface. In addition, the angle of the cutting blade can be changed in response to changes in the gradient of the work surface, and the cutting blade can be cut in parallel along the work surface with a gradient. There is an effect that the cutting work can be done at a height that can be rubbed.

請求項２の発明は、刈刃保持部の刈刃を車輪幅よりも外側に出して固定することにより、塀ぎわであっても直進状態で作業ができるという効果がある。   The invention of claim 2 has an effect that the cutting blade of the cutting blade holding part is fixed to the outside of the wheel width and fixed, so that the work can be performed in a straight line state even if it is a wrinkle.

駆動パイプ及び前記ハンドルパイプと、前記軸受シャーシ及び前記車輪とが前記シャーシの位置で前後方向の水平軸回りに左右に傾くようにして、刈刃保持部の刈刃に対して前記軸受シャーシ及び前記車輪が前後方向の水平軸回りに左右に傾くように構成することにより、実現した。 A driving pipe and the handle pipe, and the bearing chassis and the wheels so as to incline in the left-right in the longitudinal direction of the horizontal axis at the position of the chassis, the bearing chassis and the relative cutting blade of the cutting blade holder This was realized by configuring the wheels to tilt left and right around the horizontal axis in the front-rear direction .

It is.

図において、１は車輪、２は車輪１の各車軸３を支持する軸受シャーシ、４は軸受シャーシ２に左右首振り用縦軸５により左右に回転可能に取り付けたシャーシ半体Ａ、６は軸受シャーシ２に取り付けた左右首振り用固定板、７は左右首振り用固定板６に設けた左右首振り用長穴、８はシャーシ半体Ａ４に取り付けられて左右首振り用長穴７内に嵌りかつ左右首振り用固定板６を止める左右首振り用固定ノブ、９はシャーシ半体Ａ４にスイング軸１０により左右にスイング可能に取り付けたシャーシ半体Ｂ、１１はシャーシ半体Ｂ９が取り付けられる駆動パイプ、１２は駆動パイプ１１の先端に取り付けた刈刃保持部、１３は安全カバー１４によりカバーした刈刃、１５は駆動パイプ１１の基端に取り付けたエンジン、１６はシャーシ半体Ｂ９に取り付けたハンドルパイプで、ハンドル部１７を有している。   In the figure, 1 is a wheel, 2 is a bearing chassis that supports each axle 3 of the wheel 1, 4 is a chassis half A, 6 that is attached to the bearing chassis 2 so as to be rotatable left and right by a left and right swinging vertical axis 5. Left and right swinging fixing plate attached to the chassis 2, 7 is a left and right swinging oblong hole provided in the left and right swinging fixing plate 6, and 8 is attached to the chassis half A4 and is placed in the left and right swinging oblong hole 7. A left / right swing fixing knob that fits and stops the left / right swing fixing plate 6, a chassis half B attached to the chassis half A 4 so as to swing left and right by a swing shaft 10, and 11 a chassis half B 9. A driving pipe, 12 is a cutting blade holding part attached to the tip of the driving pipe 11, 13 is a cutting blade covered by a safety cover 14, 15 is an engine attached to the base end of the driving pipe 11, and 16 is a chassis half B. The handle pipe attached to, and has a handle portion 17.

図１〜図５に示す状態では、スイング軸１０を回転中心として２個のシャーシ半体Ａ４，Ｂ９が互いに回転（スイング）できるので、シャーシ半体Ａ４の車輪１側を固定（変動しない）としてハンドル部１７を左右に傾けると、シャーシ半体Ｂ９がスイング軸１０を回転中心に回転（スイング）して刈刃保持部１２の刈刃１３が左右に傾く。   In the state shown in FIGS. 1 to 5, since the two chassis halves A4 and B9 can rotate (swing) with the swing shaft 10 as the center of rotation, the wheel 1 side of the chassis half A4 is fixed (does not vary). When the handle portion 17 is tilted left and right, the chassis half B9 rotates (swings) about the swing shaft 10 and the cutting blade 13 of the cutting blade holding portion 12 tilts left and right.

即ち、走行中において、ハンドル部１７を真っ直ぐ（平行）に保っていると、図６に示すように走行面（作業面）の凹み１８に片方の車輪１が落ちても、シャーシ半体Ａ４がスイング軸１０を回転中心に回転（スイング）するので、シャーシ半体Ｂ９側の刈刃保持部１２の刈刃１３が傾くことなく作業面に平行に保ち、作業面に沿って平行に刈れる。   That is, if the handle portion 17 is kept straight (parallel) during traveling, even if one wheel 1 falls into the recess 18 on the traveling surface (work surface) as shown in FIG. Since the swing shaft 10 rotates (swings) about the rotation center, the cutting blade 13 of the cutting blade holding part 12 on the chassis half B9 side is kept parallel to the work surface without being tilted and can be cut in parallel along the work surface.

また、このようにハンドル部１７の操作により刈刃保持部１２の刈刃１３を左右に自在に傾けられるので、作業面の勾配変化に対しても刈刃１３の傾き角度を合わせて勾配のある作業面に沿って平行に刈れるし、さらに作業面に対して刈刃１３を擦るような高さに自在に変更できるのできわ刈り作業も可能となる。   Further, since the cutting blade 13 of the cutting blade holding portion 12 can be freely tilted to the left and right by operating the handle portion 17 as described above, the inclination angle of the cutting blade 13 is adjusted to match the gradient change of the work surface. It is possible to mow in parallel along the work surface and further change the height so that the cutting blade 13 is rubbed against the work surface.

次に、図１〜図５に示す状態では、左右首振り用縦軸５を回転中心として軸受シャーシ２に対して（左右首振り用固定板６に対しても）シャーシ半体Ａ４側（シャーシ半体Ｂ９側も）が左右に回転できるので、例えば図７に示すようにハンドル部１７を左に回転させた位置で左右首振り用固定ノブ８を締め付けると、左右首振り用長穴７を利用して左右首振り用固定板６がシャーシ半体Ａ４に固定されて図示のように刈刃１３が車輪１幅よりも外側に出た状態となる。この状態で直進してゆけば、車輪１幅から外側に出た刈刃１３により塀ぎわ刈りができる。   Next, in the state shown in FIGS. 1 to 5, the chassis half A4 side (chassis) with respect to the bearing chassis 2 (also with respect to the left and right swing fixing plate 6) with the left and right swinging vertical axis 5 as the rotation center. The half body B9 side can also be rotated left and right. For example, when the left and right swing fixing knob 8 is tightened at the position where the handle portion 17 is rotated to the left as shown in FIG. Utilizing this, the left and right swinging fixing plate 6 is fixed to the chassis half A4, and the cutting blade 13 protrudes outside the width of the wheel 1 as shown. If the vehicle goes straight in this state, it can be mowed by the cutting blade 13 that protrudes outward from the width of the wheel 1.

本実施例では軸受部の異なる実施例を図８〜図１０を用いて説明する。図８は図３に相当する図、図９は図４に相当する図、図１０は図５に相当する図であり、図中前記した実施例１のものと同一または相当部分には同一符号を付して説明を省略する。   In the present embodiment, different embodiments of the bearing portion will be described with reference to FIGS. 8 is a view corresponding to FIG. 3, FIG. 9 is a view corresponding to FIG. 4, and FIG. 10 is a view corresponding to FIG. 5. In FIG. The description is omitted.

図において、１９は駆動パイプ１１が回転可能に貫挿されるシャーシで、左右首振り用縦軸５により軸受シャーシ２に対して左右に回転できるようになっている。なお、ハンドルパイプ１６は駆動パイプ１１に取り付けられている。   In the figure, reference numeral 19 denotes a chassis through which the drive pipe 11 is rotatably inserted, and the chassis can be rotated left and right with respect to the bearing chassis 2 by the vertical swing shaft 5. The handle pipe 16 is attached to the drive pipe 11.

図８〜図１０に示す状態では、ハンドル部１７を左右に傾けると駆動パイプ１１がシャーシ１９内で回転するので、そのまま刈刃保持部１２の刈刃１３が左右に傾くし、また左右首振り用縦軸５を回転中心として軸受シャーシ２に対して（左右首振り用固定板６に対しても）シャーシ１９側（駆動パイプ１１側も）が左右に回転する。   In the state shown in FIGS. 8 to 10, when the handle portion 17 is tilted to the left and right, the drive pipe 11 rotates in the chassis 19, so that the cutting blade 13 of the cutting blade holding portion 12 is tilted to the left and right, and the left and right swings. The chassis 19 side (also the drive pipe 11 side) rotates to the left and right with respect to the bearing chassis 2 (and also to the left and right swing fixing plate 6) about the vertical axis 5 for rotation.
