Description

교체형 예초기 칼날판과 칼날{omitted}Replaceable mower blades and blades {omitted}

본 고안은 예초기 칼날에 관한 것으로써 드로잉된 칼날판에 칼날을 쉽게 고정 할 수 있게 한 것이다.The present invention relates to a mower blade, so that the blade can be easily fixed to the blade plate drawn.

예초기는 잡초, 가는 잡목을 제거하기 위해 시동이 걸린 엔진을 등에 걸머지어 동력이 전달된 후렉시블 와이어에 의해 회전구에 전달되어 칼날을 회전 시켜 잡초를 절단시키는 것으로써 회전 칼날이 흙이나 돌에 부딪힐 경우 파손된 칼날이 회전력에 의해 주위의 사람에게 피해를 줄 수 있다. 예초기 칼날이 손상 받아 파손된칼날 전체를 교체해야 하는데 교체하는데는 쉽지 않으며 교체 비용이 많이 드는 결점이 있다.The mower is transmitted to the turning hole by a flexible wire that is powered by the engine that has been started to remove weeds and fine lumber, and the blade is rotated to cut the weeds. In this case, the damaged blade can be damaged by people around you by the rotational force. The damaged blades have to be replaced because of the damaged blades, which is not easy to replace and has a costly defect.

본 고안은 예초기의 칼날이 일체형 칼날판과 칼날이 조합 착탈 시키는 삼각형 사각형이 있으며 칼날 교체시 교체의 방법이 쉽지 않으므로 누구나 쉽게 할 수 없는 불편함을 제거하기 위해 분리된 회전판에 칼날을 드로잉되어 돌출된 홈에 끼워 교체가 쉽게 사용할 수 있도록 한 것이다. 따라서 본 고안은 회전판의 끝단부에 칼날을 끼울 수 있게 드로잉하여 돌출 시켜 형성된 홈을 이용해 칼날을 착탈 시킬 수 있게 한 것이다. 이러한 본 고안은 예초기의 끝단 회전구에 칼날이 끼워진 칼날판을 끼워 고정하여지며 예초기의 회전 동력을 전달받아 회전된 칼날판 세곳의 등 간격으로 이루어진 끝단에 드로잉되어 형성된 홈에 끼어진 칼날은 회전력에 의해 외측으로 빠져나가려는 외력에 의해 칼날 끝단의 턱에 칼날이 칼날판에 고정되어 이루어진다.The present invention has a triangular square that the blade of the blade cutter and the integrated blade and detachable blade, and the replacement method is not easy when replacing the blade, so that the blade is drawn on the separate rotating plate to eliminate the inconvenience that anyone can not easily It fits in the groove for easy replacement. Therefore, the present invention is to draw the blade to the end of the rotating plate to be detachable by using a groove formed by protruding the blade. The present invention is fixed by inserting a blade plate fitted with blades on the rotary end of the lawn mower, the blade is inserted into the groove formed by drawing at the end of the three equal intervals of the blade plate rotated by the rotational power of the lawn mower to the rotational force The blade is fixed to the blade plate on the jaw of the blade end by the external force to exit to the outside by.

1. 홈이 돌출된 칼날판1. Blade plate with groove

2. 칼날2. Blade

본 고안은 예초기의 회전구 지지대에 조립되어 회전되는 칼날판(1)의 3등분된 외측의 끝단의 등간격에 형성된 드로잉되어 돌출되어진 홈에 내측으로부터 외측의 방향으로 끼워져 턱이 닿이는부까지 끼워진 칼날(2)은 회전구의 회전력에 의하여 외부로 빠지려는 원심력에 의해 고정되어지는 것이다. 드로잉된 부분은 칼날이 끼울수 있게 홈이 주어져 등 간격의 3개로 이루어진다. 본 고안은 칼날판이 120°의 등간격으로 3개의 칼날(2)이 끼워지는 구조이다. 칼날판이 외측 등간격으로 형성된 칼날 결합 홈부는 프레싱 작업시 드로잉으로 홈이 주어지며 적은 공정으로 제작이 가능하다. 칼날판에 드로잉되어 돌출 형성된 홈은 칼날(2)폭과 칼날(2)뚜께의 치수보다 약간 큼으로 칼날이 쉽게 조립 될 수 있는 치수로 주어진다.The present invention is fitted in the direction from the inner side to the outer side of the drawing and protruding grooves formed at equal intervals of the third end of the outer end of the blade plate (1) that is assembled and rotated on the rotary supporter of the lawn mower The blade 2 is to be fixed by the centrifugal force to fall out by the rotational force of the rotary sphere. The drawn part is grooved so that the blade can be fitted into three equally spaced gaps. The present invention is a blade plate is a structure in which the three blades (2) are fitted at equal intervals of 120 °. The blade engaging groove portion of which the blade plate is formed at equal intervals outside is given a groove by drawing during pressing operation and can be manufactured in a small process. The protruding groove drawn on the blade plate is slightly larger than the width of the blade (2) and the width of the blade (2), so that the blade can be easily assembled.

이로써 본 고안은 회전되는 칼날판과 칼날로 간단하게 형성되는 구조로 되어있으므로 누구나 쉽게 착탈이 가능한 것이 특징이다.As a result, the present invention has a structure that is simply formed by a rotating blade plate and the blade is characterized by anyone can be easily removable.

본 고안은 예초기의 칼날을 칼날판에 쉽게 착탈이 가능하며 단순한 구조로써 이루어지므로 경제적 이점이 있다.The present invention has an economic advantage because the blade of the lawn mower can be easily attached to or detached from the blade plate and is made of a simple structure.
