Description

【考案の詳細な説明】 本考案は携帯用刈払機における回転刃の保護板に関する
ものである。
[Detailed Description of the Invention] The present invention relates to a protection plate for a rotary blade in a portable brush cutter.

携帯用刈払機は、第1図の側面図にみられるように、エ
ンジン1からメインシャフトを内包したメインパイプ2
の先端に取付けた回転刃3によって草、柴等を刈る装置
であるが、回転刃が高速回転をしているために、小石そ

ので、その防護用装置が種々検討されている。
As seen in the side view of Fig. 1, the portable brush cutter runs from an engine 1 to a main pipe 2 containing a main shaft.
This is a device that cuts grass, bushes, etc. using a rotary blade 3 attached to the tip of the blade, but because the rotary blade rotates at high speed, pebbles and other small pieces may scatter towards the operator, creating a danger. Therefore, various protective devices are being studied.

なかでも、メインパイプから回転刃の後面に対して保護
板を設ける方法は簡便で効果が大であるが、従来のもの
はその固定方法が不十分であるため実用上不便をきたし
ている。
Among these methods, the method of providing a protective plate from the main pipe to the rear surface of the rotary blade is simple and highly effective, but the conventional method causes practical inconvenience because the method of fixing the protective plate is insufficient.

すなわち、メインパイプに直接保護板を固定する場合は

In other words, when the protection plate is fixed directly to the main pipe, the impact when the protection plate hits an obstacle, or the impact of the stone on the protection plate when the rotary blade hits a stone and knocks it off, is There is a disadvantage that the impact is directly transmitted to the worker, and if a soft protection plate is hung swingably to absorb such a shock, the protection plate will be unstable and undesirable.

げようとすれば、固定式では草等のつ1りで切れ味を悪
くするし、揺動式に垂設した場合は保護板が回転刃に当

If you try to increase the protective effect by installing a twisted protection plate close to the rotating blade, if it is a fixed type, the blade will be damaged by grass etc., and if it is installed vertically in a swinging type, the protection plate will be damaged. may hit the rotating blade, which is dangerous.

本考案は保護板の取付げに際して、湾曲板バネからなる
支杆を用いると共に保護板の形状についても考慮を払っ
たものである。
The present invention uses a support rod made of a curved leaf spring when attaching the protection plate, and also takes into consideration the shape of the protection plate.

図面は本考案の一実施例を示し、第1図は保護板4を取
付げた刈払機の全体側面図、第2図は刈払刃へ保護板を
取付けた部分の平面図であり、第3図は支杆と保護板の
拡大正面図、第4図は第3図A−A断面図である。
The drawings show one embodiment of the present invention; FIG. 1 is an overall side view of a brush cutter with a protection plate 4 attached, FIG. 2 is a plan view of a portion of the brush cutter with the protection plate attached, and The figure is an enlarged front view of the support rod and the protection plate, and FIG. 4 is a sectional view taken along the line AA in FIG. 3.

これらの図で明らかなように、保護板4はメインパイプ
2に湾曲板バネからなる支杆5を介して取付金具6によ
って取付ける。
As is clear from these figures, the protection plate 4 is attached to the main pipe 2 with a mounting bracket 6 via a support rod 5 made of a curved leaf spring.

湾曲板バネからなる支杆は図面のようにほぼ半円形の板
バネを2本突出させてメインパイプの両側へ平行に設け
ているが、この2本の湾曲板バネを1枚の幅広い1体物
にしてメインパイプの通る部分のみ円弧状に切欠いても
差支えない。
As shown in the drawing, the support rod made of curved leaf springs has two approximately semicircular leaf springs protruding from each other and is installed parallel to both sides of the main pipe.These two curved leaf springs are combined into one wide body. There is no problem even if you make an arc-shaped notch only in the part where the main pipe passes.

ここで、はぼ半円形の湾曲板バネは回転刃方向に凸な湾
曲面を向けると、刈った草や石が支杆の弾性で適当に衝
撃を吸収すると共に下方へ落下して、回転刃に保護板を
接近させてもその間に草が詰することかない。
Here, when the semicircular curved leaf spring faces the convex curved surface toward the rotating blade, the mown grass and stones absorb the impact appropriately with the elasticity of the support rod and fall downward, causing the rotating blade to Even if the protective plate is placed close to the grass, grass will not get stuck between the protective plates.

また、第4図の右方、すなわち外方から保護板を押す場
合はバネ力が強く働き、保護板が回転刃に接触すること
がなく安全である。
Moreover, when pushing the protection plate from the right side in FIG. 4, that is, from the outside, the spring force acts strongly and the protection plate does not come into contact with the rotary blade, making it safe.

保護板4は、第3図、第4図に示すように、回転刃2が

れぞれ補強用打出部7,8を設け、かつ保護板の両側は
固転刃を包むように前方へ15〜30度折り曲げている
As shown in FIGS. 3 and 4, when the rotary blade 2 rotates counterclockwise, the protective plate 4 is extended to the left side from the center, and is designed to be as light and strong as possible at the center and outer periphery. Reinforcing protrusions 7 and 8 are provided on each side, and both sides of the protective plate are bent forward by 15 to 30 degrees so as to wrap around the fixed blade.

As described above, when the protection plate is supported by a support rod made of a curved leaf spring at the rear of the rotary blade of the brush cutter, the protection plate is fixed securely and with appropriate elasticity, so that stones thrown by the rotary blade can be removed. Not only can it accurately prevent debris from flying toward the worker, but it can also alleviate the shock caused by rocks or the like colliding with the protection plate, allowing safe and comfortable brush cutting work.
