Description

【0001】
【産業上の利用分野】
本発明は、畦の草刈りや樹木の根元等の下草刈等に使用する歩行型自走式草刈り機に関する。
【0002】
【従来の技術】
左右一対の走行輪あるいは1個の走行輪を備えた走行機体の前部に縦軸を中心に回転する刈刃を設けた刈刃ケースを取り付けた歩行型自走式草刈機は、例えば、実開昭59−166616号公報や実開昭63−68729号公報等に記載されている。
また、このような歩行型自走式草刈機で、畦等の傾斜面の刈り取り作業を容易にすべく、刈刃ケースを走行機体の左右片側に前後方向の軸を中心にして左右に揺動するようにした構成のものが例えば実開平6−68409号公報に記載されている。
【0003】
【発明が解決しようとする課題】
前記の歩行型自走式草刈機は、刈刃ケースを支持するために、走行機体から刈刃ケースの上方を超えて、前方へ延びる車輪支持アームを設け、この支持アームの先端に走行輪の略真前に位置して前輪を取り付け、刈刃が地面に沿って回転するように刈刃ケースを支持している。この構成では刈刃ケースの前方に前輪が位置しているため、樹木の根元や塀の際などに接近して草を刈り取ることができない。
そこで、本発明では、前方に障害物があってもその障害物の極く近くまで刈刃ケースを接近させて草刈りができるようにすることを課題とする。
【0004】
【課題を解決するための手段】
駆動輪1を装架し後方に向けてハンドル杆2を立設した機体フレーム3に対して刈刃4を装架した刈刃ケース5を左右片側に偏位して揺動可能に枢着し、先端に遊動輪6を枢支した車輪支持アーム7を前記刈刃ケース5と反対側で機体フレーム3に遊動輪6の位置を上下調節可能でかつ伸縮固定可能に設けると共に、遊動輪6を車輪支持アーム7の左右に位置変更して固定可能にし、遊動輪6を刈刃ケース5の前側で駆動輪1の略真前位置と刈刃ケース5の側部位置とに固定可能にした。
【0005】
【発明の作用及び効果】
この歩行型自走式草刈機を使用して畦等の前方に障害物が無い場所で草を刈る場合には、車輪支持アーム7を伸ばして遊動輪6を刈刃フレーム5の前方に位置固定して、機体フレーム3を水平に保持したままで、刈刃フレーム5が地面の左右傾きに沿って揺動しながら走行させて作業が行え、作業が安定し楽である。
【0006】
また、樹木の根元や塀際等の草を刈る場合には、車輪支持アームを縮めて遊動輪6を刈刃ケース5の側部に固定することで、刈刃ケース5の先端が樹木や塀に接近することができ、刈り取り範囲が広がることになる。
【0007】
【実施例】
次に、本発明の一実施例を図面を参照しながら説明する。
機体フレーム3には、原動機10を搭載し、1個の駆動輪1を装架し、後斜め上方に向けてハンドル杆2を突設している。
左右のハンドル杆2の先端握り部11の下部には走行クラッチレバー12と刈り取りクラッチレバー13を設け、左ハンドル杆2の前部にチェンジレバー14とスロットルレバー15とを設けて、作業者がハンドル杆2の握り部11を持って走行しながら前進し刈取作業を行うようにしている。
【0008】
刈刃ケース5は、垂直回転軸16に取り付けた取付アーム17の先端に取り付けた刈刃4の回動範囲を覆う下側が開いたケースで前後方向の前軸18と後軸19で機体フレーム3に左右揺動可能に取り付けている。
20は刈刃フレーム5の側部を受ける補助輪である。
【0009】
刈刃ケース5の前側は側部が開口して取入口21を形成していて、その上部に支軸22を横架し、この支軸22に短冊状の板体23を遊嵌し、各板体23間にカラー24を遊挿し、板体が前後方向及び左右方向に揺動可能としている。
機体フレーム3の刈刃ケース5と反対側には後方へ延びる操作杆25の取付ブラケット26を支軸27で取り付け、複数の引掛部を形成した係止枠28に操作杆25の途中を引っ掛けて遊動輪6の上下高さを調節するようにしている。
【0010】
取付けブラケット26には四角孔を形成し、前後方向の車輪支持アーム7を嵌合させ、ピン29で車輪支持アーム7を伸縮して固定するようにしている。
車輪支持アーム7の先端には遊動輪6を左右位置変更可能に支軸30で取り付けている。31は左右位置で固定する引張ばねである。
【0011】
畦や道端等の前方に障害物が無い場合には、遊動輪6を図1の実線位置として刈取走行を行い、樹木の根元等の草刈りを行う場合には、遊動輪6を図1の想像線位置にして刈刃ケース5の側方に遊動輪6を位置させて刈取り作業を行うのである。
刈取高さを変更するには、操作杆25と係止杆28の係止位置を変更して遊動輪6の高さを変更する。

[Industrial application fields]
The present invention relates to a walk-type self-propelled mower used for mowing a bush or under-cutting a tree root or the like.
[0002]
[Prior art]
A walking type self-propelled grass mower having a cutting blade case provided with a cutting blade rotating around a vertical axis at the front of a traveling machine body having a pair of left and right traveling wheels or one traveling wheel is, for example, It is described in Japanese Utility Model Laid-Open No. 59-166616 and Japanese Utility Model Laid-Open No. 63-68729.
Also, with such a walk-type self-propelled mower, the cutting blade case is swung left and right about the front and rear axis on the left and right sides of the traveling machine body in order to facilitate the cutting of slanted surfaces such as reeds. For example, Japanese Utility Model Laid-Open No. 6-68409 discloses a configuration having such a configuration.
[0003]
[Problems to be solved by the invention]
In order to support the cutting blade case, the walking self-propelled mower has a wheel support arm that extends forward from the traveling machine body to above the cutting blade case. A front wheel is attached at a position almost directly in front, and the cutting blade case is supported so that the cutting blade rotates along the ground. In this configuration, since the front wheel is located in front of the cutting blade case, the grass cannot be cut close to the root of the tree or the edge of a bush.
Therefore, an object of the present invention is to make it possible to cut grass by bringing the cutting blade case close to the obstacle even if there is an obstacle ahead.
[0004]
[Means for Solving the Problems]
A cutting blade case 5 on which a cutting blade 4 is mounted is pivotally attached to the left and right sides of a machine frame 3 on which a driving wheel 1 is mounted and a handle rod 2 is erected on the rear side so as to be swingable. The wheel support arm 7 pivotally supporting the idler wheel 6 at the tip is provided on the machine body frame 3 on the opposite side of the cutting blade case 5 so that the position of the idler wheel 6 can be adjusted up and down, and the idler wheel 6 can be fixed. The left and right positions of the wheel support arm 7 can be changed to be fixed, and the idler wheel 6 can be fixed to the front side of the cutting blade case 5 at a position substantially in front of the driving wheel 1 and a side position of the cutting blade case 5.
[0005]
[Action and effect of the invention]
When using this walking type self-propelled mowing machine to cut grass in a place where there are no obstacles in front of a fence or the like, the wheel support arm 7 is extended and the idler wheel 6 is fixed in front of the cutting blade frame 5. Then, while the machine body frame 3 is held horizontally, the cutting blade frame 5 can be operated while swinging along the horizontal inclination of the ground, so that the operation is stable and easy.
[0006]
In addition, when cutting grass such as the root of a tree or the edge of a tree, the tip of the cutting blade case 5 is fixed to the side of the cutting blade case 5 by contracting the wheel support arm so that the tip of the cutting blade case 5 is fixed to the tree or bush. The cutting range will be expanded.
[0007]
【Example】
Next, an embodiment of the present invention will be described with reference to the drawings.
A motor frame 10 is mounted on the body frame 3, a single drive wheel 1 is mounted, and a handle bar 2 projects from the rear obliquely upward.
A traveling clutch lever 12 and a mowing clutch lever 13 are provided below the front end grip 11 of the left and right handlebars 2, and a change lever 14 and a throttle lever 15 are provided at the front of the left handlebar 2, so that an operator can handle Advancing while carrying the grip portion 11 of the heel 2 to perform the cutting operation.
[0008]
The cutting blade case 5 is a case in which the lower side that covers the rotation range of the cutting blade 4 attached to the tip of the mounting arm 17 attached to the vertical rotating shaft 16 is open, and the body frame 3 is constituted by the front shaft 18 and the rear shaft 19 in the front-rear direction. It is attached to the left and right so that it can swing left and right.
Reference numeral 20 denotes an auxiliary wheel that receives the side portion of the cutting blade frame 5.
[0009]
The front side of the cutting blade case 5 is open at the side to form an intake 21, a support shaft 22 is horizontally mounted on the upper portion thereof, and a strip-shaped plate body 23 is loosely fitted to the support shaft 22. A collar 24 is loosely inserted between the plate bodies 23 so that the plate bodies can swing in the front-rear direction and the left-right direction.
A mounting bracket 26 of an operating rod 25 extending rearward is attached to the opposite side of the machine body frame 3 from the cutting blade case 5 by a support shaft 27, and the operating rod 25 is hooked halfway on a locking frame 28 having a plurality of hook portions. The height of the idler wheel 6 is adjusted.
[0010]
A square hole is formed in the mounting bracket 26, the wheel support arm 7 in the front-rear direction is fitted, and the wheel support arm 7 is extended and fixed by a pin 29.
An idler wheel 6 is attached to the tip of the wheel support arm 7 with a support shaft 30 so that the left and right positions can be changed. Reference numeral 31 denotes a tension spring which is fixed at the left and right positions.
[0011]
When there is no obstacle in front of a fence or roadside, the idler wheel 6 is used for cutting and running with the position of the solid line in FIG. 1, and when mowing the root of a tree or the like, the idler wheel 6 is illustrated in FIG. The mowing operation is performed with the idler wheel 6 positioned on the side of the cutting blade case 5 in the line position.
In order to change the cutting height, the height of the idler wheel 6 is changed by changing the locking position of the operating rod 25 and the locking rod 28.
