Description

예초기용 강선 와이어 커터{the steel wire wire cutter for grass mower}{the steel wire wire cutter for grass mower}

본 발명은 예초기의 회전축 선단에 나사결합되어 잔디나 잡초 등의 풀을 베는 예초기용 강선 와이어 커터에 관한 것으로, 더욱 상세하게는 통상적으로 사용하는 나일론 커터 대신에 스텐이나 강철선으로 된 강선 와이어 커터로 구성하여 마모율을 감소시키고 절삭효율을 높이며, 강선 와이어 커터의 교체를 간편하게 한 예초기용 강선 와이어 커터에 관한 것이다. The present invention relates to a steel wire cutter for a lawn mower that is screwed to the tip of a rotation shaft of a lawn mower to cut grass such as grass or weeds, and more particularly, it is composed of a steel wire wire cutter made of stainless steel or steel wire instead of a normally used nylon cutter. It relates to a steel wire wire cutter for a mower that reduces abrasion rate, increases cutting efficiency, and facilitates replacement of the steel wire wire cutter.

일반적으로, 예초기는 정원, 묘지, 공원 등에 심어진 잔디나 잡초를 짧게 깍아주기 위해 사용되는 장치로서, 휘발유 등의 연료에 의해 구동되는 엔진의 회전축 선단에 휠 또는 사각형의 금속 커터를 장착하여 엔진의 작동으로 고속 회전시켜 잡초나 풀 및 잡목 등을 절단하는데 사용된다.In general, a mower is a device used to mow grass or weeds planted in a garden, a cemetery, a park, etc. short, and a wheel or a rectangular metal cutter is mounted on the tip of a rotating shaft of an engine driven by fuel such as gasoline to operate the engine. It is used to cut weeds, grass, and weeds by rotating it at high speed.

그러나 상기와 같은 금속재의 커터는 직경이 작은 나뭇가지를 제거하기에 용이하고, 잡초를 절단하는 효율이 좋으나, 절삭 작업 중에 나무의 그루터기, 바위 또는 돌 등에 부딪히는 경우에는 금속재의 커터 또는 바위 등이 파손되고 이 과정에서 파편이 튀어 안전사고를 유발하는 경우가 많았다. However, the metal cutter as described above is easy to remove small-diameter branches and has good weed cutting efficiency. In the process, there were many cases where fragments were thrown and caused a safety accident.

따라서, 근래에는 이와 같은 문제점을 해결하기 위해 굵은 나뭇가지 아닌 잡초나 잔디 등과 같이 비교적 부드러운 풀을 벨 때에는 합성수지제인 나일론 커터를 많이 사용하고 있다. Therefore, in recent years, in order to solve this problem, a nylon cutter made of synthetic resin is widely used when cutting relatively soft grass such as weeds or grass instead of thick branches.

그러나 이러한 나일론 커터는 금속재 커터에 비해 안전성은 있으나 쉽게 마모되어 잦은 교체를 해야 되고 절삭효율 또한 우수하지 못한 문제점이 있었다. However, these nylon cutters have more safety than metal cutters, but they wear out easily, so they have to be replaced frequently, and the cutting efficiency is also not excellent.

본 발명의 목적은 이와 같은 종래의 문제점을 해결하기 위한 데 있는 것으로 종래에 사용되는 나일론 커터를 강선으로 된 강선 와이어 커터로 대체하고 이를 커터헤드에 간편하게 장착할 수 있게 하여 교체작업 또한 편리하게 한 예초기용 강선 와이어 커터를 제공하는 데 있다. An object of the present invention is to solve the problems of the related art, and it is a mower that replaces a conventionally used nylon cutter with a steel wire wire cutter made of steel wire and makes the replacement operation convenient by making it possible to easily mount it on the cutter head. To provide a steel wire cutter for steel wire.

본 발명은 이와 같은 목적을 달성하기 위한 수단으로, 예초기의 회전축이 결합되는 너트가 인서트된 상부하우징, 상기 상부하우징과 결합되는 하부하우징으로 이루어진 커터헤드와, 상기 커터헤드의 사이에 끼워져 인출블럭의 인출공을 통해 인출되는 와이어 커터로 이루어진 것에 있어서, 상기 와이어 커터는 스텐 또는 강철선으로 구성된 강선 와이어 커터로 이루어지고, 상기 강선 와이어 커터는 내측단부에 하향 절곡부가 형성되어 상부하우징의 중앙에 돌설된 지지부재의 안내홈을 통해 삽입공에 삽입 장착되도록 구성됨을 특징으로 하는 예초기용 강선 와이어 커터를 제공한다. The present invention is a means for achieving the above object, and a cutter head comprising an upper housing into which a nut to which the rotation shaft of the lawn mower is coupled is inserted, and a lower housing coupled to the upper housing, and the cut-out block inserted between the cutter head. In the case of a wire cutter drawn out through a draw-out hole, the wire cutter is made of a steel wire cutter made of a stainless steel wire or a steel wire, and the steel wire wire cutter has a downward bent portion formed at an inner end of the support protruding from the center of the upper housing. It provides a steel wire cutter for a mower, characterized in that it is configured to be inserted and mounted in the insertion hole through the guide groove of the member.

이와 같이 본 발명은 종래의 나일론 커터를 강선 와이어 커터로 대체하여 마모율을 감소시킴으로써 수명을 길게 하고 절삭효율을 높이는 효과가 있을 뿐 아니라 와이어 커터를 커터헤드에 간편하게 설치하고 분리할 수 있게 함으로써 예초작업시에 마모된 와이어 커터의 교체작업을 줄일 수 있어 경제적이고 작업능률을 향상시킬 수 있는 효과가 있다. As described above, the present invention replaces the conventional nylon cutter with a steel wire cutter and reduces the wear rate, thereby extending the lifespan and increasing cutting efficiency. It is economical and has the effect of improving work efficiency as it can reduce the replacement work of the worn wire cutter.

이하 본 발명을 구체적인 실시예를 도시한 첨부도면에 의거 상술하면 다음과 같다. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings showing specific embodiments thereof.

본 발명의 예초기용 강선 와이어 커터는, 도 1 내지 도 5에 도시된 바와 같이, 예초기의 회전축이 결합되는 너트(1)가 인서트된 상부하우징(20), 상기 상부하우징(20)과 결합되는 하부하우징(10)으로 이루어진 커터헤드(30)와, 상기 커터헤드(30)의 사이에 끼워져 인출블럭(40)의 인출공(41)을 통해 인출되는 와이어 커터(50)로 이루어진 것에 있어서, 상기 와이어 커터(50)는 스텐 또는 강철선으로 구성된 강선 와이어 커터(50)로 이루어지고, 상기 강선 와이어 커터(50)는 내측단부에 하향 절곡부(51)가 형성되어 상부하우징(20)의 중앙에 돌설된 지지부재(11)의 안내홈(12)을 통해 삽입공(60)에 삽입 장착되도록 구성됨을 특징으로 한다. As shown in FIGS. 1 to 5, the steel wire cutter for a lawnmower of the present invention includes an upper housing 20 into which a nut 1 to which a rotation shaft of a lawnmower is coupled is inserted, a lower portion coupled to the upper housing 20 In the case of the cutter head 30 made of the housing 10, and the wire cutter 50 inserted between the cutter head 30 and drawn out through the drawing hole 41 of the drawing block 40, the wire The cutter 50 is made of a steel wire cutter 50 made of a stainless steel wire or a steel wire, and the steel wire cutter 50 has a downward bent portion 51 formed at the inner end thereof, protruding from the center of the upper housing 20 It is characterized in that it is configured to be inserted and mounted in the insertion hole 60 through the guide groove 12 of the support member 11 .

이와 같이 된 본 발명의 강선 와이어 커터(50)는 도 1에 도시된 바와 같이 커터헤드(30)의 상부하우징(20)과 하부하우징(10)의 사이에 인출공(41)을 통해 대향되게 인출되어 엔진의 구동으로 회전되는 회전축에 의해 회전되면서 잡초와 풀을 절삭하게 되는 것으로, 커터헤드(30)에 끼워지는 와이어 커터(50)를 종래의 나일론 커터 대신에 내구성이 매우 우수한 스텐 및 강철선으로 구성한 것이므로 마모율이 매우 적어 풀베기 작업 도중에 종래와 같이 와이어 커터(50)를 자주 교체해야 되는 번거로움이 없고 이로 인해 연속적인 작업을 할 수 있으므로 작업효율이 높아지는 장점이 있다. As shown in FIG. 1, the steel wire cutter 50 of the present invention is drawn out oppositely through the draw-out hole 41 between the upper housing 20 and the lower housing 10 of the cutter head 30 as described above. It cuts weeds and grass while being rotated by the rotating shaft rotated by the driving of the engine. Therefore, the wear rate is very low, so there is no need to frequently replace the wire cutter 50 as in the prior art during the mowing operation.

또한, 강선 와이어 커터(50)는 내측단부가 하향 절곡되어 인출공(41)을 통해 상부하우징(20)의 중앙에 돌설된 지지부재(11)의 안내홈을 통해 삽입공(60)에 삽입되어 장착되므로 강선 와이어 커터(50)는 인출공(41)과 지지부재(11)의 안내홈 그리고 삽입공(60)에 견고하게 장착되어 회전과정에서 움직이지 않고 커터작업을 실시할 수 있게 되며, 강선 와이어 커터(50)를 장착하거나 분해할 때 커터헤드(30)의 상부하우징(20)과 하부하우징(10)을 분리하면 간단하게 강선 와이어 커터(50)를 장착하고 분해할 수 있으므로 매우 편리하다.In addition, the steel wire wire cutter 50 is inserted into the insertion hole 60 through the guide groove of the support member 11 protruding from the center of the upper housing 20 through the lead-out hole 41 with the inner end bent downward. Since it is mounted, the steel wire cutter 50 is firmly mounted in the lead-out hole 41, the guide groove of the support member 11, and the insertion hole 60, so that the cutter operation can be performed without moving during the rotation process. When the wire cutter 50 is mounted or disassembled, if the upper housing 20 and the lower housing 10 of the cutter head 30 are separated, the steel wire wire cutter 50 can be simply mounted and disassembled, so it is very convenient.

특히, 상부하우징(20)에 삽탈식으로 설치되는 인출블럭(40)에 인출공(41)이 관통되어 있으므로 인출블럭(40)을 빼낸 후 강선 와이어 커터(50)를 끼워 다시 조립한 상태에서 지지부재(11)의 안내홈에 끼워 삽입공(60)에 삽입 장착하면 설치가 완성되고 분해할 때에는 역순으로 빼내면 되므로 강선 와이어 커터(50)의 설치 및 분해가 매우 용이하다. In particular, since the draw-out hole 41 is penetrated in the draw-out block 40 installed in the upper housing 20 in an insertable and detachable manner, after the draw-out block 40 is pulled out, the steel wire cutter 50 is inserted and supported in the reassembled state. The installation and disassembly of the steel wire cutter 50 are very easy because it is inserted into the guide groove of the member 11 and inserted into the insertion hole 60 to complete the installation.

이와 같이 본 발명은 커터가 강선 와이어 커터(50)로 이루어져 마모성이 적어 내구성이 우수하고 이로 인해 경제적인 효과를 얻을 수 있고, 또 강선 와이어 커터(50)의 설치 및 분해 작업이 매우 편리하여 취급이 매우 용이할 뿐 아니라 작업효율이 향상되는 효과를 제공한다.As described above, in the present invention, since the cutter is made of the steel wire cutter 50, it has excellent durability due to low abrasion resistance, thereby obtaining an economical effect. It is very easy and provides the effect of improving work efficiency.
