Blade for mower capable of preventing a drive shaft mounted with a blade from being twisted by plants and ensuring the smoothness of the blade during rotation
A blade for a mower is disclosed, which can be driven by a drive shaft to rotate about a rotational center. The blade comprises at least one cutting portion and a mounting portion connected with the cutting portion. The mounting portion comprises a base wall connected with the cutting portion and at least one auxiliary cutting wall that is protruded relative to the base wall and disposed adjacent to the rotational center. With the auxiliary cutting wall disposed adjacent to the rotational center and protruded relative to the base wall, plants close to the rotational center can be cut when the blade is rotated, so as to prevent the drive shaft mounted with the blade from being twisted by the plants and ensure the smoothness of the blade during rotation.一種割草機的刀片,可被一驅動軸驅動並沿著一個旋轉中心轉動,該刀片包含至少一個切割部,以及一個與該切割部連接的安裝部,該安裝部具有一個與該切割部連接的基壁,以及至少一個相對於該基壁突出並鄰近該旋轉中心的輔助切割壁。利用鄰近該旋轉中心且相對於該基壁突出之輔助切割壁,可以在該刀片旋轉的過程中,切割靠近該旋轉中心的植物,以防止植物纏繞在帶動該刀片轉動的驅動軸上,並確保該刀片在旋轉時的順暢性。2‧‧‧刀片20‧‧‧長度方向21‧‧‧切割部211‧‧‧主刀刃22‧‧‧安裝部221‧‧‧基壁222‧‧‧輔助切割壁223‧‧‧組裝孔224‧‧‧穿孔225‧‧‧孔緣226‧‧‧輔助刀刃
