Abstract
본 고안은 예초기의 절단구에 관한 것이다.The present invention relates to a cutting device of a mower.
종래에 예초기의 절단구는 다수의 금속칼날로 구성하고 있어, 예초작업 중 이 금속칼날이 돌이나 고형체와 부딪히면 파손되어진 파편으로 인하여 안전사고가 발생하는 폐단이 있었으므로 이를 해결하고자 금속으로 된 칼날 대신에 굵고 단단한 나일론 재질로 된 회전절단 끈을 좌우에 한가닥씩 인출되게 함으로서 안전사고는 많이 줄었으나, 상기 회전절단 끈은 이의 수가 매우 적음에 따라 작업성이 저조할 뿐만 아니라 쉽게 마모되므로 자주 교체하여야 하는 폐단이 있었던 것이다.Conventionally, the cutting tool of the lawn mower is composed of a plurality of metal blades, and during the mowing operation, when the metal blade hits a stone or solid body, there was a closed end that caused a safety accident due to the fragments that were broken. Safety accidents are reduced by pulling out the cutting string made of thick and hard nylon one by one strand on the left and right side. However, the rotation cutting strap is not only poor workability but also wears easily because the number is very small. There was a dissolution.
본 고안은 상기의 문제점을 해결하고자 안출한 것으로, 이의 고안 요지는 예초기에 설치된 절단구 몸체(1)의 내부에 장착된 장너트(7)의 측부에는 회전절단 끈(9)을 고정하는 체결볼트(6)와 다수의 걸림턱(5)이 형성되고, 몸체(1)의 외주연에는 회전절단 끈(9)이 인출되는 다수의 인출공(2)과 절단구 몸체(1)를 예초기(10)에서 분리 또는 체결 시에 사용되는 공구 끼움공(3)을 형성한 것으로, 이는 종래의 예초기의 절단구에 비하여 구조가 간단하고 회전절단 끈(9)의 개수가 많아 작업능률이 양호할 뿐만 아니라 회전절단 끈(9)의 교체가 용이한 특징이 있는 것이다.The present invention has been made to solve the above problems, the subject matter of the present invention is a fastening bolt for fixing the rotary cutting string (9) to the side of the nut (7) mounted on the inside of the cutting body (1) installed in the lawn mower 6 and a plurality of engaging jaw (5) is formed, the outer periphery of the body (1) mowing the plurality of outlet holes (2) and the cutting body (1) for drawing the rotary cutting string (9) The tool fitting hole (3) to be used at the time of separation or fastening is formed, which is simpler in structure than the cutting tool of the conventional lawnmower and has a large number of rotary cutting strings (9), which not only improves work efficiency. Rotational cutting string (9) is characterized by easy replacement.
Description
본 고안은 예초기의 절단구에 관한 것이다.The present invention relates to a cutting device of a mower.
종래의 예초기의 절단구는 다수의 금속칼날로 구성되어 있어 작업 도중 칼날이 돌이나 기타 물체와 접할 시 파손된 파편이 비산되어 안전사고를유발하였으므로 이를 개선하고자 금속으로 된 칼날 대신에 굵고 단단한 나일론 재질로 된 회전절단 끈을 사용함으로서 안전사고는 많이 줄었으나 상기한 회전절단 끈은 절단구의 좌우측에 한가닥씩 돌출시켰기 때문에 작업능률이 저조할 뿐 아니라 쉽게 마모됨으로서 자주 교체를 해야 하는 폐단이 있었던 것이다.The cutting device of the conventional mowing machine is composed of a plurality of metal blades, and when the blade comes in contact with stones or other objects during operation, the broken fragments scattered, causing safety accidents. Safety accidents were reduced by using the rotary cutting straps, but the rotary cutting straps were protruded one by one on the left and right sides of the cutting tool, so that the work efficiency was not only low but also easily worn, so there was a need for frequent replacement.
본 고안은 상기의 문제점을 해결하고자 안출한 것으로, 이의 고안 요지는 절단구 몸체(1)의 내부에는 나일론 재질의 회전절단 끈(9)을 고정하는 체결볼트(6)와 걸림턱(5)이 다수 형성되고, 절단구 몸체(1)의 외주연에는 상기 회전절단 끈(9)이 인출되는 다수의 인출공(2)과 예초기(10)의 선단부 체결 및 해제시 사용되는 공구 끼움공(3)을 형성함으로서 종래에 비하여 회전절단 끈(9)의 개수가 많아 작업성이 양호할 뿐만 아니라 마모된 회전절단 끈(9)의 교체 시는 이의 교체가 용이하게 한 것이다.The present invention has been devised to solve the above problems, the subject matter of the present invention is a fastening bolt 6 and the locking jaw (5) for fixing the rotary cutting string (9) made of nylon inside the cutting body (1) A plurality of tool holes (3) formed at the outer periphery of the cutting body (1) are used to fasten and release the leading end of the plurality of drawing holes (2) and the lawn mower (10) with which the rotary cutting string (9) is drawn out By forming a larger number of the rotary cutting string (9) than the conventional workability is good as well as when replacing the worn rotary cutting string (9) is to facilitate the replacement thereof.

이를 도면에 의거하여 자세하게 설명하면 다음과 같다.This will be described in detail with reference to the drawings as follows.
예초기(10)의 선단부에 체결되어 풀을 벨 때 사용되는 절단구 몸체(1)의 하단 중앙부에는 움푹 파인 형상의 요입부(1a)가 형성되고, 이의 내부 중심 통공부에는 예초기(10)의 선단부 및 덮개(8)의 체결볼트(6)가 체결되는 장너트(7)를 장착하되이 장너트(7)는 일반 나사와 달리 나사산이 역방향으로 형성되어 있으며, 상기 장 너트(7)의 외측에는 다수의 걸림턱(5)이 돌출 형성되고, 상기 몸체(1)의 외주연에는 다수의 인출공(2)과 한 개의 끼움공(3)이 형성되며, 또한 몸체(1)의 하부 중앙에 형성된 요입부(4a)에는 상기한 덮개(8)가 나사산이 역방향으로 형성된 체결볼트(6)에 의해 체결되게 한 것이다.A recessed indentation portion 1a is formed in the lower center of the cutting body 1 used to cut the grass by fastening to the distal end of the lawn mower 10, and the inner end of the lawn mower 10 is formed at the distal end of the lawn mower 10. And a long nut 7 to which the fastening bolt 6 of the cover 8 is fastened, but the long nut 7 is formed in a reverse thread unlike a general screw, and is provided on the outer side of the long nut 7. The engaging jaw (5) of the protruding, the outer periphery of the body (1) has a plurality of outlet holes (2) and one fitting hole (3) is formed, also formed in the lower center of the body (1) In the mouth portion 4a, the cover 8 is fastened by a fastening bolt 6 in which threads are formed in the reverse direction.
상기와 같이 구성된 본 고안은 예초기의 절단구인바, 이의 실시예는 다음과 같다.The present invention configured as described above is a cutting tool bar mower, the embodiment thereof is as follows.
직경이 2.5∼3.0Φ 정도 되는 단단한 재질인 나일론 끈을 30cm 정도의 길이로 다수개 절단한 후 이를 각각 절반으로 접어서 상기 절단구 몸체(1)의 내부에 형성된 걸림턱(5)에 8자형으로 끼운 다음 두가닥으로 된 회전절단 끈(9)의 선단부를 인출공(2)을 통해 인출시킨다. 그리고 상기한 덮개(8)를 몸체(1)의 하측 요입부(1a)에 씌워 체결볼트(6)로 상기한 장너트(7)에 체결하여 절단구 몸체(1)를 구성한 후 이의 체결공(4)에 예초기(10)의 선단부를 나사 체결하여 사용하면 되는 것이다.Cut a plurality of nylon straps of rigid material having a diameter of about 2.5 to 3.0 Φ in a length of about 30 cm, and then fold them in half and insert them in the shape of an engaging jaw (5) formed inside the cutting body (1) in an eight shape. Next, the leading end of the two-piece rotary cutting string 9 is drawn out through the drawing hole 2. Then, the cover 8 is covered with the lower concave portion 1a of the body 1, and the fastening bolt 6 is fastened to the long nut 7 to form the cutting body 1, and then the fastening hole thereof ( In 4), the front end of the lawn mower 10 may be screwed together to be used.
따라서 본 고안은 다수의 회전절단 끈(9)이 절단구 몸체(1)의 주변에 방사선상으로 인출되어 고속 회전되면서 예초할 수 있게 하였기 때문에 작업능률을 현저히 높일 수 있을 뿐만 아니라 회전절단 끈(9)은 여러가닥으로 수명이 길어서 자주 교체할 필요가 없고 절단구 몸체(1)를 예초기(10)에서 분리 및 결합하고자 할 때는 몸체(1)에 형성된 공구 끼움공(3)에 공구를 끼워 돌리면 간단히 분해 및 체결할 수 있는 것이다.Therefore, the present invention has a number of rotary cutting strings (9) are drawn out radially around the cutting body (1) to be mowed while rotating at high speed, not only can significantly increase work efficiency, but also rotary cutting strings (9). ) Is a long service life with multiple strands, so it is not necessary to replace it frequently. When you want to remove and combine the cutting body (1) from the mower (10), simply turn the tool into the tool fitting hole (3) formed on the body (1). It can be disassembled and fastened.
상기한 바와 같이 본 고안은 절단구 몸체(1)의 내부에는 다수의 걸림턱(5)을 형성하고, 주면에는 다수의 인출공(2)을 형성하여 다수의 회전절단 끈(9)이 방사선상으로 끼움 인출되어 체결볼트(6)에의 고정되게 하였기 때문에 종래의 예초기에 비해 회전절단 끈(9)은 수명이 길어서 자주 교체할 필요가 없으므로 작업효율이 훨씬 양호하고 또한 이를 교체 시는 교체작업이 용이할 뿐만 아니라 안전사고를 방지할 수 있어 매우 유용한 것이다.As described above, the present invention forms a plurality of locking jaws 5 in the inside of the cutting tool body 1, and a plurality of drawing holes 2 are formed on the main surface thereof so that the plurality of rotary cutting strings 9 are radially wound. Since it is pulled out and fixed to the fastening bolt (6), the rotary cutting string (9) has a long life compared to the conventional mowing machine, so it does not need to be replaced frequently, so the work efficiency is much better and it is easy to replace when replacing it. In addition to preventing accidents, it is very useful.
