예초정리용 상부커버{Upper cover for weeder blade}Upper cover for weeder blade}

본 발명은 예초정리용 상부커버에 관한 것으로, 더욱 상세하게는 예초 작업시 무작위 방향으로 흩뿌려지던 예초 및 잡목들을 일정한 방향으로 가지런히 정리되도록 함으로써 예초칼날에 가해지던 부하를 방지하고, 예초작업 후 절단된 예초들의 청소 및 정리가 용이하도록 하는 예초정리용 상부커버에 관한 것이다.The present invention relates to a top cover for mowing, and more particularly, to prevent the load applied to the mowing blade by arranging the mowing and scrubs scattered in a random direction during mowing in a uniform direction, and after mowing The present invention relates to a lawn mower top cover that facilitates cleaning and cleaning of the cut mowers.

일반적으로 예초기는 농가, 묘소, 골프장 등에서 불규칙하게 자란 잔디나 잡초를 제거하기 위해 사용되는 것으로, 동력에 의해 칼날이 수평으로 회전하도록 상기 칼날은 칼날구동수단이 내장된 헤드부의 회전축에 장착되어 고속으로 회전하게 된다.In general, the lawn mower is used to remove grass or weeds that are irregularly grown in farms, graveyards, golf courses, etc., so that the blades are horizontally rotated by power, and the blades are mounted on the rotating shaft of the head unit in which the blade driving means is built. Will rotate.

이러한 예초기는 칼날이 외부로 노출된 상태에서 고속으로 회전하므로 고르지 못한 지면이나 자갈 등에 칼날이 부딪치면 칼날이 부러지거나 자갈, 돌 등이 튀어올라 작업자나 주변사람들이 크게 다치게 되고, 실수로 작업자가 칼날에 근접하는 경우 상기 칼날에 크게 다치게 되는 등 안전사고가 빈번하게 일어나는 장치중의 하나이다.These mowers rotate at high speed while the blades are exposed to the outside, so when the blade hits the uneven ground or gravel, the blade breaks or the gravel, stone, etc. pops up, causing serious injury to workers or people around them. In case of approaching one of the devices, safety accidents occur frequently, such as a serious injury to the blade.

따라서 상기한 문제점을 해결하기 위해 등록실용신안공보 제20-0177854호의 "예초기 커터의 안전커버"와, 공개특허공보 제10-2000-0039562호의 "예초기 커터의 안전커버 및 안전사고 방지방법"과, 등록실용신안공보 제20-0337868호의 "안전커버를 갖는 예초기"와, 공개특허공보 제10-2005-0081398호의 "예초기의 칼날보호커버"에는 예초기의 칼날을 보호하고 상부로 돌이나 자갈 등이 튀어올라 작업자가 다치는 것을 방지하기 위해 상기 칼날 상부에 안전커버 또는 칼날보호커버(이하, '상부커버'라 총칭함)를 형성하고 있다.Therefore, in order to solve the above problems, "Safety cover of the lawn mower cutter" of Korean Utility Model Publication No. 20-0177854, "Safety cover and safety accident prevention method of the lawn mower cutter" of Publication No. 10-2000-0039562, and The "cutting machine with a safety cover" of the Utility Model Publication No. 20-0337868 and the blade protection cover of the cutting machine of the Patent Publication No. 10-2005-0081398 protect the blade of the cutting machine and the stone or gravel is splashed on the top In order to prevent the worker from being injured, a safety cover or blade protection cover (hereinafter, collectively referred to as 'upper cover') is formed on the upper edge of the blade.

그러나 상기한 종래의 상부커버들은 예초 작업시 절단된 예초(刈草)들을 일정한 방향으로 모아주거나 하는 기능이 결여되어 있어 무작위 방향으로 날리면서 일부는 상부커버의 상면에 얹히거나 일부는 다시 날리면서 다시 예초칼날에 잘리기도 하는 등 부하(負荷)로 작용하기도 한다.However, the conventional upper covers lack the function of collecting the cut grass (刈草) cut in a certain direction during the mowing operation, so that some fly on the top surface of the top cover or some mowing again while flying in a random direction The blade may also be cut and act as a load.

따라서 작업자는 종종 예초기를 기울이거나 또는 흔들어서 상부커버의 절단된 예초들을 털어내야 하는 번거로움을 가지게 되며, 또 사방으로 흩어져 날린 예초들에 의해 예초칼날이 지나간 자리를 알 수 없게 되어 작업이 곤란하고, 특히 예초작업 후 절단된 예초들을 한 곳에 모아 정리하는데 상당한 시간이 소요되는 불편함이 있었다.Therefore, the worker often has the trouble of tilting or shaking the mower to shake off the cut mowers of the upper cover, and it is difficult to work because the mowing blades are scattered in all directions and do not know where the mowing blade has passed. In particular, there was an inconvenience that it takes a considerable time to gather and cut the cut grass cut in one place after mowing.

따라서 본 발명은 상기와 같은 문제점을 해결하기 위해 창안된 것으로, 본 발명은 칼날구동수단이 내장된 헤드부의 회전축에 장착되는 예초칼날을 보호하기 위해 상기 예초칼날의 상부에 형성되는 상부커버에 있어서, 상기 상부커버는 예초칼날을 보호하기 위해 예초칼날의 상부에 형성되는 보호판과, 상기 보호판의 상부면에 일측단부는 맞닿아 작업자의 진행방향, 즉 전방을 향하도록 하고 타측단부는 각각 측후방을 향하도록 수직으로 돌출형성되어지되 호(弧)형상을 갖는 한쌍의 정리판과, 상기 보호판의 후방에는 저부가 개방되고 상단에 힌지결합구를 구비하는 보호판 결합부와, 상기 보호판 결합부가 결합되기 위한 힌지돌기를 구비하는 작업봉 결합부로 이루어지는 예초정리용 상부커버를 제공하기 위한 것이다.Therefore, the present invention was devised to solve the above problems, the present invention is in the upper cover formed on the top of the mowing blade to protect the mowing blade mounted on the rotating shaft of the head portion is built-in blade driving means, The upper cover is a protective plate formed on the top of the cutting blade to protect the cutting blade, and one side end is in contact with the upper surface of the protective plate to face the traveling direction, that is, the front of the operator and the other end is respectively lateral rear A pair of rearranging plates which protrude vertically so as to have an arc shape, a protective plate coupling portion having a bottom opening at the rear of the protective plate, and a hinge coupler at an upper end thereof, and a hinge protrusion for coupling the protective plate coupling portion.
