Abstract

【課題】草刈作業中に樹脂ブレード草刈刃の本体下部が、地面に接地した状態で高速回転する場合が多いので、磨耗・損傷してしまう不都合と、草刈刃が地面に接触しないように地面から浮かせて作業しているので、作業者の負担になっている不都合を解消すること。
【解決手段】保護カバーを大型にして、内部にベアリングを取り付け、刈刃の回転の影響を受けずに自由に回転できるようにし、また、保護カバーの内側に、回転軸への草の巻き付きを防止する金属板を取り付けることにより、この問題を解決する。
【選択図】図１PROBLEM TO BE SOLVED: There are many cases where a lower part of a main body of a resin blade mowing blade rotates at high speed while being in contact with the ground during mowing work, and there is an inconvenience that the mowing blade is not in contact with the ground. Since the work is suspended, the inconvenience that is a burden on the operator is eliminated.
SOLUTION: A protective cover is made large and a bearing is attached inside so that it can freely rotate without being affected by the rotation of the cutting blade. Also, grass is wrapped around the rotating shaft inside the protective cover. This problem is solved by attaching a metal plate to prevent.

Description

本考案は、刈払機に取り付け、作業機能を向上させ、作業者の負担を軽減する、刈払機用接地安定型樹脂ブレード草刈刃に関するものである。The present invention relates to a ground-stable resin blade mowing blade for a brush cutter, which is attached to a brush cutter, improves work functions, and reduces the burden on an operator.

従来の刈払機用樹脂ブレード草刈刃の本体は、薄い金属板を成形したものだが、草刈り作業中に地面に接触することは多い。The main body of a conventional brush blade resin blade mowing blade is a thin metal plate, but it often comes into contact with the ground during mowing work.

１）草刈作業中に樹脂ブレード草刈刃の本体下部が、地面に接地した状態で高速回転する場合が多いので、磨耗・損傷してしまう。また作業者は、できるだけ地面に草刈刃が接触しないように、地面から刈刃を浮かせた状態で作業しているので、作業者の負担になっている。1) During the mowing operation, the lower part of the main body of the resin blade mowing blade often rotates at a high speed while being in contact with the ground, so it is worn and damaged. Moreover, since the operator is working in a state where the cutting blade is lifted from the ground so that the grass cutting blade is not in contact with the ground as much as possible, it is a burden on the operator.

１）草刈刃の下側に、草刈刃の影響を受けずに自由に回転する接地安定盤を装着して、接地安定型樹脂ブレード草刈刃とする。1) A grounding stabilization board that rotates freely without being affected by the mowing blade is attached to the lower side of the mowing blade to obtain a grounding-stable resin blade mowing blade.

１）草刈刃と接地安定盤は固定されておらず、自由に回転するので、地面に接地した状態で草刈作業をしても、磨耗・損傷が少ない。また、作業者が接地安定盤を地面に接地した状態で草刈作業ができるので、作業者にかかる負担が大幅に軽減される。1) The mowing blade and grounding stabilizer are not fixed and rotate freely, so there is little wear and damage even when mowing while grounded on the ground. Further, since the operator can perform the mowing work with the grounding stabilization board in contact with the ground, the burden on the worker is greatly reduced.

本考案に係る刈払機用接地安定型樹脂ブレード草刈刃１は、図１のように中心部の取り付けボルト２が地面に接触して損傷しないように、接地安定盤４の中央部に平らな窪みが形成されている。安定盤内側の中心部にベアリング３が取り付けられており、接地安定盤は、このベアリングを介して刈払機の回転軸に取り付けられるので、草刈刃の回転の影響を受けずに自由に回転する。安定盤の高さは、低過ぎると刈刃が地面に接触しやすくなり、高過ぎると草が短く刈れないので、適度な高さとする。
刈払機の回転軸への取り付け方法は、接地安定盤中心部のボルト１本のみで容易に着脱可能な構造とする。
材質は、錆びにくく、薄い金属板で、長期間地面に接触しても磨耗しない強度のあるもので、一体成型が望ましい。The ground stabilization type resin blade mowing blade 1 for a brush cutter according to the present invention has a flat recess at the center of the ground stabilization board 4 so that the mounting bolt 2 at the center does not come into contact with the ground and is damaged as shown in FIG. Is formed. A bearing 3 is attached to the center of the stabilizer, and the ground stabilizer is attached to the rotary shaft of the brush cutter through this bearing, so that it freely rotates without being affected by the rotation of the mowing blade. If the height of the stabilization board is too low, the cutting blade will easily come into contact with the ground, and if it is too high, the grass will be short and cannot be mowed.
The brush cutter is attached to the rotating shaft with a structure that can be easily attached and detached with only one bolt at the center of the ground stabilization board.
The material is hard to rust, is a thin metal plate, and has a strength that does not wear even if it is in contact with the ground for a long period of time.
