Description
図1〜図6は、本発明に係わる刈払い用回転刃の一実施形態を示している。図1〜図3に示すように、刈払い用回転刃1(回転刃1という)は、円板状の台金2を有し、この台金2の中心位置には、後述する刈払い機5への取付孔3が形成されている。
Claims (2)
- 円板状の台金の外周縁に刃先を有する刈払い用回転刃において、前記台金は、その中心部分に刈払い機への取付孔が形成された取付平坦部と、該取付平坦部の外側に反刈払い機側である台金の裏面側に突出する状態で形成された円環状の膨出部と、該膨出部の外側に台金の外周縁方向に向けて前記取付平坦部と略同一面状に延設された刃先平坦部とを備え、
前記膨出部の高さが、前記取付平坦部を刈払い機に取付ボルトで取り付けた際に、該取付ボルトの突出寸法より大きく設定されると共に、該膨出部の円周方向の所定位置に、膨出部が摩耗した場合でも前記刃先平坦部と取付平坦部の連結を維持可能な連結維持部が複数設けられ、該連結維持部は、前記膨出部の底部を台金の取付平坦部側に凹ませることで設けた凹部であると共に、該凹部の底部は、前記刃先平坦部に対する寸法を取付平坦部側が大きく刃先平坦部側が小さく設定することにより傾斜していることを特徴とする刈払い用回転刃。 - 前記膨出部は、その地面と接触する刃先平坦部側の側壁の傾斜角度が20〜45度に設定されていることを特徴とする請求項1に記載の刈払い用回転刃。
