摘要:
This design protects the blade from foreign objects such as stones during work by moving the blade of the mower to a certain height from the ground, and can be easily mowed with little force by pushing it in contact with the ground without lifting the blade. It relates to a safety cover for mowers that can be mounted and used. To this end, the present invention, in the lawn mower provided with a blade portion provided with a rotating shaft for rotating the power to receive power, and a boss for holding the blade coupled to the rotating shaft of the blade portion, the blade is located on the lower portion of the blade A predetermined length smaller than a diameter and a convex ball portion at a lower portion thereof so as to separate the blade from the ground by a predetermined height; a ball shaft portion protruding in a cylindrical shape a predetermined length higher than the height of the ball portion from an inner central portion of the ball portion, and the ball. A bearing in which the outer ring is integrally rotated with the ball shaft part, the mounting cap is inserted into the shaft and integrally rotates with the inner ring, and the shaft is perforated in the central part thereof; The rotary shaft coupled to the shaft is inserted into the shaft hole of the mounting cap so that the boss is in close contact with the inner ring of the bearing A fastening nut for fastening the mounting cap and the rotating shaft are integrally provided on the. The ball portion has a plurality of wings are formed radially to protrude outward the radius of rotation of the blade on its outer peripheral surface to protect the blade.본 고안은 예초기의 칼날을 지면으로부터 일정 높이 이격시켜 작업시 돌멩이 등의 이물질로부터 칼날을 보호하고 칼날부를 들지 않고 지면에 닿은 상태에서 밀고 다님으로써 적은 힘으로 손쉽게 벌초할 수 있을 뿐만 아니라 어느 예초기에도 손쉽게 장착하여 사용할 수 있도록 한 예초기용 안전커버에 관한 것이다. 이를 위하여, 본 고안은 동력을 전달받아 회전하는 회전축이 마련된 칼날부와, 상기 칼날부의 회전축에 축 결합된 칼날을 잡아주기 위한 보스가 구비된 예초기에 있어서, 상기 칼날의 하부에 위치하되 상기 칼날의 직경보다 소정길이 작게 형성되며 지면으로부터 상기 칼날을 일정 높이 이격시킬 수 있도록 그 하부가 볼록한 볼부와, 상기 볼부의
