Abstract

The present invention relates to a rotary blade used in a lawnmower. More specifically, a metal wire is integrally inserted into a rotary blade to increase durability, so that the rotary blade is not easily damaged even when used for a long time, and the weight of the rotary blade is increased to enhance cutting power. To this end, the present invention is integrally manufactured by inserting the metal wire into a rotary blade. When the lawnmower is used, the rotary blade is not easily damaged even when the rotary blade comes into contact with a grainy object such as stone or wood. In addition, the rotary blade has a sense of weight to provide more effective cutting of grasses such as weeds while rotating.

Description

예초기용 회전칼날줄{Rotary blade for lawn trimmer}Rotary blade for lawn trimmer{Rotary blade for lawn trimmer}

본 발명은 예초기에 사용되는 회전칼날줄에 관한 것으로, 보다 상세하게 설명하면 회전칼날줄에 내측에 금속와이어를 일체로 삽입제작하므로 내구성을 높여 장시간 사용하여도 쉽게 파손되지 않도록 하고 회전칼날줄의 중량감을 높여 절삭력을 높일 수 있도록 발명한 것이다.The present invention relates to a rotary blade used in a lawnmower, and in more detail, it is manufactured by inserting a metal wire inside the rotary blade to increase durability, so that it is not easily damaged even after a long period of use, and the weight of the rotary blade It was invented to increase cutting power by increasing the value.

일반적으로 예초기의 칼날부에는 다양한 종류가 있어 사용용도에 따라 칼날부를 교체하면서 예초기를 사용하게 된다.In general, there are various types of blades of a lawnmower, and a lawnmower is used while replacing the blades according to the intended use.

특히 잡초와 같은 풀을 제거하기 위해서는 합성수지로 제작된 회전칼날줄을 이용하게 된다In particular, to remove grass such as weeds, a rotating blade made of synthetic resin is used.

종래의 회전칼날줄은 재질이 합성수지로 제작되어 있어 사용중에 돌이나 나무에 접촉하게 되면 회전칼날줄이 파손되거나 경질의 풀이 용이하게 절삭되지 않는 경우가 종종 발생하였다.Conventional rotating blades are made of synthetic resin, so when they come into contact with stones or wood during use, the rotating blades are often damaged or hard grass is not easily cut.

상기 회전칼날줄이 파손이 될 시에는 회전칼날줄을 고정하는 회전칼날고정부를 분해하고 회전칼날줄을 회전칼날부로부터 분리하여 적당한 길이로 다시 조절해서 장착해야 하므로 많은 번거로운 문제점이 있었으며 합성수지로 제작된 회전칼날줄이 쉽게 파손되어 사용자는 다시 재구매해야 하는 문제점이 있었다.When the rotating blade is damaged, the rotating blade fixing part that fixes the rotating blade must be disassembled, and the rotating blade must be separated from the rotating blade and adjusted to an appropriate length.Therefore, there are many cumbersome problems, and it is made of synthetic resin. The old rotating blade was easily damaged, so the user had to repurchase again.

문제점이 있었던 것이다.There was a problem.

이와 같은 문제점으로 회전칼날줄이 장시간 사용하여도 파손되지 않는 제품이 요구되어 왔었다.Due to this problem, a product that does not break even if the rotating blade is used for a long time has been required.

이에 본 발명은 상기한 바와 같은 문제점을 해결하기 위한 것으로서, 회전칼날줄의 내구성을 높여서 하나의 제품으로 장시간 사용하여도 쉽게 파손되지 않도록 하였으며 회전칼날줄을 이용하여 잡초와 같은 풀을 절삭할 시에 절삭능력이 우수하도록 하여 작업시간을 줄일 수 있도록 제공함에 그 목적이 있다.Accordingly, the present invention is to solve the above-described problems, and the durability of the rotating blade is increased so that it is not easily damaged even when used as a single product for a long time. When cutting grass such as weeds using the rotating blade, Its purpose is to provide excellent cutting ability to reduce working time.

상기와 같은 목적을 달성하기 위하여 본 발명은 회전칼날줄의 내측에 금속와이어를 삽입하여 일체로 제작한 것으로,In order to achieve the above object, the present invention is integrally manufactured by inserting a metal wire into the inside of a rotary blade,

예초기를 사용할 시에 돌이나 나무와 같은 경질의 물체에 접촉하여도 쉽게 파손되지 않으며 또한 회전칼날줄이 무게감이 있어서 회전을 하며 잡초와 같은 풀을 보다 효과적으로 절단할 수 있도록 제공함에 그 목적이 있다.The purpose of this is to provide for more effective cutting of grass such as weeds while using a lawnmower, which is not easily damaged even if it comes into contact with hard objects such as stones or trees, and also rotates because of the weight of the rotary blade.

이상 설명한 바와 같이 본 발명은 회전칼날줄의 내부에 금속와이어를 장착하므로 회전칼날줄의 내구성을 높여서 하나의 제품으로 장시간 사용하여도 쉽게 파손되지 않도록 하였으며 회전칼날줄을 이용하여 잡초와 같은 풀을 절삭할 시에 회전칼날줄의 중량감을 높이므로 절삭능력이 우수하도록 할 수 있으며 이러한 우수한 절삭효과를 통하여 작업시간을 줄일 수 있는 효과가 있는 것이다.As described above, in the present invention, since the metal wire is mounted inside the rotating blade, the durability of the rotating blade is increased so that it is not easily damaged even when used as a single product for a long time, and grass such as weeds is cut using the rotating blade. When doing it, it increases the weight of the rotating blade, so that the cutting ability can be excellent, and through this excellent cutting effect, there is an effect of reducing the working time.

이하 본 발명의 실시예를 첨부된 예시도면을 참고로 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

엔진의 동력에 의해 고속으로 회전하는 예초기(1)와, 예초기의 끝부분에 회전칼날줄(2)이 장착되어 있는 회전칼날고정부(3)로 구성되어 있는 공지의 예초기(1)에 있어서,In the known lawn mower (1) consisting of a lawn mower (1) rotating at high speed by the power of the engine and a rotary blade fixing unit (3) equipped with a rotary blade (2) at the end of the lawn mower,

회전칼날줄(2)은 단면이 사각형으로 길게 형성되어 있는 것으로, 사용자가 적당한 크기로 잘라서 회전칼날줄(2)을 회전칼날고정부(3)에 장착하여 사용하게 된다.The rotary blade 2 has a long rectangular cross section, and the user cuts it to an appropriate size and installs the rotary blade 2 on the rotary blade fixing part 3 to use.

본 발명은 합성수지로 이루어진 회전칼날줄(2)의 내부에 금속와이어(4)를 삽입하여 일체로 제작한 것으로,The present invention is made integrally by inserting a metal wire (4) into the inside of the rotating blade (2) made of synthetic resin,

금속와이어(4)는 얇은 금속줄이 여러겹으로 꼬여서 제작하므로 쉽게 절단되지 않는 것이다.The metal wire 4 is not easily cut because a thin metal wire is twisted in several layers.

상기 금속와이어(4)의 내부틈새에도 합성수지가 침투되도록하여 합성수지와 와이어금속(4)이 일체로 형성되도록 한다.The synthetic resin penetrates into the internal gap of the metal wire 4 so that the synthetic resin and the wire metal 4 are integrally formed.

도 3에서 표현한 바와 같이 회전칼날줄(2)의 내부에 금속와이어(4)를 삽입하여 제작하므로 예초기(1)를 이용하여 잡초와 같은 풀을 제거할 시에 금속와이어(4)가 잡아주므로 회전칼날줄(2)의 파손을 줄일 수 있도록 한 것이다.As shown in Fig. 3, since it is manufactured by inserting a metal wire 4 into the inside of the rotary blade 2, the metal wire 4 holds it when removing grass such as weeds using the lawnmower 1, so it rotates. This is to reduce the breakage of the blade (2).

특히 회전칼날줄(2)이 회전하면서 돌이나 나무에 부딪혀도 회전칼날줄(2)의 내부에 있는 금속와이어(4)가 외측에 있는 사각합성수지를 잡아주므로 회전칼날줄(2)의 파손을 막을 수 있도록 한 것이다.In particular, even if the rotating blade 2 rotates and collides with a stone or wood, the metal wire 4 inside the rotating blade 2 holds the square synthetic resin on the outside, thus preventing the damage of the rotating blade 2 I did it.

또한 회전칼날줄(2)의 내부에 금속와이어(4)를 장착하므로 전체적인 회전칼날줄(2)의 무게가 증가되고 이와 같이 회전칼날줄(2)을 회전할 시에 중량감에 의하여 절삭효과를 높일 수 있는 것이다.In addition, since the metal wire 4 is installed inside the rotating blade 2, the overall weight of the rotating blade 2 is increased, and the cutting effect is enhanced by the weight when rotating the rotating blade 2 as described above. It can be.

즉 경질의 나무 잔가지를 제거할 시에 종래의 회전칼날줄(2)을 이용하면 튕겨져 나갈 수 있지만 본원발명의 회전칼날줄(2)은 중량감과 금속와이어(4)가 외측의 합성수지를 잡아주므로 내구성을 높이고 절삭효과를 증대할 수 있도록 한 것이다.That is, when removing hard twigs, it can be repelled by using a conventional rotary blade (2), but the rotary blade (2) of the present invention has a sense of weight and the metal wire (4) holds the synthetic resin on the outside, so it is durable. This is to increase the cutting effect and increase the cutting effect.
