本発明は、刈払機を使用する際に片手操作が可能となる
ように工夫された刈払機の支持装置に関するものである
。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a support device for a brush cutter that is devised to enable one-handed operation when using the brush cutter.
山間部における急傾斜地の斜面で刈払作業を行う際作業
者は、姿勢が不安定な状態になるところから、例えば第
１図に示すように斜面に立木Ｘがある場合、片手で立木
Ｘをつかんで姿勢を安定化し、他方の手で刈払機を片手
操作する方が安全性の面で好ましい。When cutting grass on a steep slope in a mountainous area, the worker may be in an unstable position.For example, if there is a tree From a safety standpoint, it is better to grab the handle to stabilize your posture and use your other hand to operate the brush cutter with one hand.
ところが従来の刈払機の支持形態では、吊りバンド‘こ
よって刈払機の操作村の基端部を作業者の肩に単に吊持
しただけであり、従って刈払機は、作業者の身体に対し
てふらついた不安定な支持状態になるところから、片手
でもつて刈払機を振り操作することは不可能であった。However, in the conventional way of supporting a brush cutter, the base end of the operating section of the brush cutter is simply suspended from the worker's shoulder using a suspension band, and therefore the brush cutter is not attached to the worker's body. It was impossible to swing and operate the brush cutter with one hand because the support was unstable and unsteady.
そこで本発明は、片手操作が可能となるような刈払機の

向に回動し得るように取付けられている。This mounting board 11 has a fork 12 on one end side and a fork 12 on the bottom side.
A mounting bracket 12 having a diameter 12a and 12a is fixedly mounted, and a horizontal shaft 13 provided with a shield at the other end has a brush cutter support 1 mounted thereon.
4 is pivotally mounted in the upper and lower directions, and one side of the brush cutter support 14 is attached to the above-mentioned upper and lower parts.
It is sandwiched between the lower forks 12a, 12a, and the range of rotation in the vertical direction is restricted. In addition, mounting bracket 1
Although not particularly shown in the drawings, it is preferable that the fixed position of the blade 2 is movable in the front and back direction (in the direction of the operation center of the brush cutter) with respect to the mounting board 11. The brush cutter support 14 is
One end is bent into a U-shape, and the other end is bent into an L-shape, with the pivot point of the horizontal shaft 13 as a boundary, and the free end of the proximal end 14a of this U-shape is , the horizontal axis 13
A cylindrical collar 16 is mounted so as to be rotatable in the left-right direction via a vertical axis 15 perpendicular to the cylindrical collar 16 .

９によって刈払機ａが前後方向に可動しないように固定
されて行われるようになっている。Further, the L-shaped bent end portion 14M is formed with a slit 17 extending in the left-right direction, along which the guide body 18 is movably arranged. It is attached to the support body 14 by the guide body 18 and the cylindrical collar 16, and the operation lever 1 of the brush cutter is loosely passed through the hole 18a formed in the guide body 18, and the operation lever 1 is inserted into the cylindrical collar 16. The base end of the village 1 is fitted together and the set screw 1 is set in the cylindrical collar 16.
9, the brush cutter a is fixed so as not to move in the front and rear directions.
なお、この固定状態において刈払機ａの操作村１は、円

によって規制かれると共に、水平軸１３を支点として上
下方向にも可動自在であるが、この可動範囲は、上、下
のフオーク１２ａ，１２ａによって規制される。In this fixed state, it is desirable that the control panel 1 of the brush cutter a has a predetermined play in the rotational direction shown by the arrow E' with respect to the cylindrical collar 16. A grip 20 is mounted in front of and facing upward. With this configuration, the brush cutter a
is first movable in the left and right directions with the vertical axis 15 as a fulcrum, and this movable direction and movable range are determined by the slit 17.
It is also movable in the vertical direction using the horizontal shaft 13 as a fulcrum, but this movable range is regulated by the upper and lower forks 12a, 12a.
従って刈払機ａは、上記垂直軸１５，水平軸１３を支点

作が可能となる。Therefore, the movable range of the brush cutter a in the left, right, upward, and downward directions using the vertical axis 15 and the horizontal axis 13 as fulcrums is restricted, so that the brush cutter a can be moved only in the prescribed directions. Because it is supported by the body of person C,
Operator c can swing the operating pestle 1 from side to side while holding the grip 20 with one hand, and the cutting blade body 3 is accordingly moved from side to side along a predetermined reciprocating trajectory in the horizontal plane, so that one-handed operation is possible. becomes possible.

ぎてバランスを崩して転倒するようなことがなく、かつ
、補助の作業者への不慮の危険も防止されるようになっ
て、刈払機による作業の安全性を一段と高めることがで
きる。Thus, according to the support device of the present invention, the operator can swing the brush cutter with one hand, so when cutting grass on a steep slope in a mountainous area, the operator can swing the brush cutter with one hand as shown in FIG. You will be able to stabilize your posture by holding on to a tree X or a suitable fixed object with your hand, and operate the brush cutter with one hand using your other hand, and in doing so, the range of swinging motion in the left and right directions will be restricted. This prevents the worker from accidentally swinging too much, causing him to lose his balance and fall, and also prevents accidental danger to auxiliary workers, improving the safety of working with the brush cutter. You can increase it even more.
なお、本発明において、前記したように取付金具１２を

。In addition, in the present invention, as described above, by configuring the mounting bracket 12 so that its fixed position can be moved back and forth with respect to the mounting board 11, the operator can easily adjust the position of the brush cutter in the front and back direction. In addition, by fixing the operating pestle 1 to the cylindrical collar 16 with a predetermined play in the direction of rotation shown by arrow E, the cutting blade body 3 can be tilted slightly in the horizontal plane during swing operation. can be done.

てもよい。Further, in carrying out the present invention, the cylindrical collar 16 may compete with the clutch case la by giving it a predetermined play in the rotational direction in advance, and may be supported on the support body 14 by the vertical shaft 15. Furthermore, in the illustrated embodiment, the mounting bracket 12 having the horizontal shaft 13 and the fork 12a is
Although the type shown is attached to the mounting board 11, forks 12a, 12 are attached to one end of the mounting board 11.
a, and the horizontal shaft 13 is provided as a shield on the pond end side, so that the brush cutter support 14 can be directly pivoted to the mounting board 11.
