Description
본 고안은 예초기 커터의 안전커버에 관한 것으로서, 보다 상세하게는 예초기의 작업봉에 쉽게 장착할 수 있으며 지면에 안착시켜 작업하여도 잡초나 넝쿨이 균일하고 부드럽게 깍이면서 예초기의 커터에 의한 안전사고는 방지하는 예초기 커터의 안전커버에 관한 것이다.The present invention relates to a safety cover of the mower cutter, more specifically, it can be easily mounted on the working rod of the mower, and even when the weed or vine is cut evenly and smoothly even when working on the ground, the safety accident by the mower cutter The safety cover of the mower cutter to prevent.
종래에는 외부에 무방비 상태로 노출되어 고속회전하는 예초기 커터에 의한 안전사고를 방지할 목적으로 외부에 다수개의 브이(V)홈이 형성되어 있으며 내부에는 커터회전홈이 형성되어 있는 상호 대칭의 반달형 커버를 예초기 커터에 씌워 사람의 다리나 큰 돌 등은 브이홈 안으로 들어올 수 없도록 하고 잡초나 넝쿨은 브이홈 안으로 들어오도록 하여 잡초나 넝쿨만 베어내도록 한 예초기 커터의 안전커버(실용신안등록 제0177854호 1999. 10. 27일 출원)가 본인에 의하여 안출되었다.Conventionally, a plurality of V (groove) grooves are formed on the outside to prevent safety accidents caused by a cutter that rotates at high speed by being exposed to the outside unprotected, and a symmetrical half-moon cover having a cutter rotation groove formed therein. The cover of the lawn mower cutter is placed on the lawn mower so that no human legs or large stones can enter the V groove, and the weeds or vines enter the V groove so that only weeds or vines can be cut. 10. 27th application) was made by me.
그러나 이러한 종래의 안전커버는 예초기의 작업봉에 장착할 때 예초기의 커터가 장착된 상태에서 볼트체결구멍에 볼트를 체결하여 커버를 장착하여야 하므로 장착이 어렵고 예초기 커터를 지면에 안착시켜 사용할 때 브이홈의 깊이가 깊지않거나 브이홈과 브이홈 사의의 돌출부의 폭이 커서 커버의 하부 경사진 면의 면적이 크면 이 경사진 면에 잡초가 눌려 잡초가 균일하게 깍이지 않아 많은 힘이 들면서도 효과는 기대에 미치지 못하는 문제점이 있었다.However, such a conventional safety cover is difficult to mount because the cover must be mounted by fastening the bolt to the bolt fastening hole while the cutter of the lawnmower is mounted on the working rod of the lawnmower, and it is difficult to install it when the lawnmower cutter is mounted on the ground. If the depth of the groove is not too deep or the width of the protrusion of the V-groove and V-groove is large, and the area of the lower inclined surface of the cover is large, the weed is pressed on the inclined surface, and the weeds are not cut evenly. There was a problem falling short of.
본 고안은 이러한 문제점을 해소하여 휴대용 예초기의 작업봉에 쉽게 장착할 수 있고 안전커버를 지면에 안착시켜 사용하여도 잡초나 넝쿨이 균일한 크기로 부드럽게 깍여 많은 힘이들지 않으면서 예초기 커터에 의한 안전사고는 방지하는 예초기 커터의 안전커버를 제공하는데 목적이 있다.The present invention solves this problem and can be easily mounted on the work stick of the portable mower, and the safety cover is secured by the mower cutter without the need for a lot of effort by gently cutting the weeds or vines into a uniform size even when the safety cover is used on the ground. The purpose is to provide a safety cover of the mower cutter to prevent accidents.
이러한 목적을 달성하기 위하여 본 고안에서는 상부원형커버를 일체로 형성하며 양측에 다수개의 브이홈과 하부에 커터회전홈을 형성하는데 커터회전홈은 예초기의 커터가 상부원형커버의 외측면으로는 노출되지 않고 하부로만 노출되도록 형성하고 중앙에는 커버장착구멍 또는 체결돌기를 형성하여 예초기의 작업봉에 간단히 장착한 후 상부원형커버의 하부에 슬라이드돌기가 형성된 슬라이드판을 부착하거나 상부원형커버와 대칭이나 커터회전홈과 커버장착구멍이 형성되어 있지 않고 브이홈은 깊게 형성되어 있는 하부원형커버를 조립하는데 특징이 있다.In order to achieve this purpose, the present invention forms an upper circular cover integrally and forms a plurality of V grooves and cutter rotating grooves on both sides thereof. The cutter rotating grooves are not exposed to the outer surface of the upper circular cover. It is formed to be exposed only to the lower part, and it is simply attached to the working rod of the mower by forming a cover mounting hole or a fastening protrusion in the center, and then attaching a slide plate having a slide protrusion on the lower part of the upper circular cover, or rotating the cutter symmetrically with the upper circular cover. The groove and the cover mounting hole are not formed, and the V-groove is characterized in assembling the lower circular cover which is deeply formed.
