Abstract
Description
Claims (4)
- 刈払機の支持棹の前端部に回転可能に取り付けられる回転体と、
前記回転体の遠心方向の外側端部に着脱可能に取り付けられる板状の切断刃とを備え、
前記切断刃は前記回転体に遠心力を付与した状態で回転方向の前側が膨らむように湾曲した形状をしたカッタユニットであって、
前記回転体には中心部から遠心方向外側に延出するように形成されて、前記切断刃が前記回転方向の前側が膨らむ向きで挿通されたときにのみスライド移動可能に案内する案内溝を設け、
前記案内溝の外側端部には前記切断刃の基端部に形成したボス部を揺動可能に軸支する支持部を設けたことを特徴とするカッタユニット。 - 請求項1に記載のカッタユニットにおいて、
前記案内溝を前記切断刃と同じ方向で湾曲させたことを特徴とするカッタユニット。 - 請求項2に記載のカッタユニットにおいて、
前記回転体には前記案内溝の溝に沿った開口部周縁にて幅方向の両端部から内側に突出する突出壁部と、前記案内溝の前記回転体における中心部から前記支持部を設けた位置と反対側に前記案内溝と連続するように湾曲して延び、前記案内溝の深さまで傾斜して前記切断刃を前記案内溝まで誘導するスロープとを備えたことを特徴とするカッタユニット。 - 請求項3に記載のカッタユニットにおいて、
前記切断刃の基端部には前記ボス部を形成した位置に他の部分より幅の広い幅広部が形成され、前記案内溝の入口部には前記切断刃が前記回転方向の前側が膨らむ向きと逆向きで挿通されたときに前記幅広部の進入を阻止する規制部を設けたことを特徴とするカッタユニット。
