본 고안은 예초기용 칼날회전체 받침구에 관한 것으로 더욱 구체적으로는 예초기의 회전칼날체를 지면에서 일정높이를 유지한 상태로 균일한 예초작업을 할수 있게 하고 칼날이 지면이나 잔돌에 닿아 손상되거나 안전사고 등을 방지하고 칼날회전체의 하중을 받쳐주는 기능으로 작업자의 장시간 작업이 용이하도록 한 예초기용 칼날보호받침구에 관한 것이다.The present invention relates to a blade rotary body supporter for mowers, and more specifically, to enable a uniform mowing operation while maintaining a constant height of the rotary blades of the mowers, and the blades are damaged or safe by touching the ground or rubble. The present invention relates to a blade protection support for lawn mowers that prevents an accident and supports a load of a blade rotating body to facilitate a long time work of an operator.

일반적으로 예초기는 우거진 숲에서 불필요한 잡초를 배기 위한 것으로, 특히 우리나라에서는 산소주변에 자란 잡초를 제거하는 벌초용도로 많이 사용되고 있다.Generally, mowers are used for exhausting unnecessary weeds in dense forests, and in particular, they are widely used for bee weeds to remove weeds grown around oxygen.

이러한 예초기는 엔진과 오일탱크를 내장한 동력전달장치 몸체를 등에 매고 동력전달장치와 연결된 작업파이프선단에 회전칼날체가 설치되어 작업자가 작업파이프를 들고 회전칼날체의 칼날에 의해 예초작업을 하도록 되어 있다.This mower is equipped with a rotary blade body at the end of the work pipe connected to the power transmission device with a power transmission body incorporating an engine and an oil tank on the back, so that the worker lifts the working pipe and mows the blade by the blade of the rotary blade body. .

그러나, 이러한 예초기에서는 작업파이프를 대략 30∼50도의 경사각을 유지토록한 다음 작업파이프선단의 회전칼날체를 지면과 수평으로 유지되게하여 지면에서 약간 띄운상태로 작업이 이루어지도록 되어 있기 때문에 작업파이프의 기울임 상태가 달라지거나 칼날회전체가 낮아지는 경우에는 칼날이 지면방향으로 향하게 되어 칼날손상뿐만 아니라 잔돌이 튀는 등 안전사고의 위험이 많았다.However, in such a lawnmower, the work pipe is maintained at an inclination angle of approximately 30 to 50 degrees, and then the rotary blade body at the tip of the work pipe is kept horizontal to the ground, so that work is performed in a slightly floating state from the ground. When the tilted state is changed or the blade rotating body is lowered, the blade is directed toward the ground, so that there are many risks of safety accidents such as blade damage and splashing.

또한, 예초작업과정에서 칼날회전체의 높낮이가 일정치 않게 되므로 잡초를 고르게 밸수 없었다.In addition, during the mowing process, the height of the blade rotating body was not constant, so weeds could not be evenly measured.

한편, 작업자가 작업파이프를 들고 작업파이프의 선단에 위치한 회전칼날체를 지탱해야되므로 작업자의 팔과 어깨에 많은 하중이 가해져서 쉽게 피로하고 장시간 작업하는데 어려움이 많았다.On the other hand, since the worker has to support the rotary blade located at the tip of the work pipe holding the working pipe, a lot of load is applied to the arm and shoulder of the worker was easy to fatigue and difficult to work for a long time.

본 고안은 이러한 문제점을 해결하기 위하여 작업파이프선단에 설치되는 칼날회전체의 하부중앙에 받침구를 설치하되 상기 받침구는 칼날회전체가 지면에서 일정높이만큼 유지되게 칼날회전체를 받쳐주며 이물질이 걸리지 않고 미끌림이동이 용이한 구성으로 된 예초기용 칼날회전체 받침구를 제공함에 있다.In order to solve this problem, the present invention installs a support hole in the lower center of the blade rotating body installed at the work pipe tip, but the supporting hole supports the blade rotating body so that the blade rotating body is maintained at a certain height on the ground and foreign substances are not caught. It is to provide a blade rotating body support for the lawn mower with a configuration that is easy to move without sliding.

"형의 받침구(30)를 설치하되 받침구(30)저면은 주연부가 곡면처리되어 경사안내되게 한 받침부(32)가 형성되고 상부의 장착판(34)중앙은 결합너트(36)가 고정설치되어 회전축부(16)에 결합너트(36)를 회전칼날체(20)의 회전반대방향으로 나사결합하여 장착고정되며 받침구(30)의 외주벽상측은 육각단면형태 또는 널링등으로 협지할 수 있는 파지면(38)이 형성되어 받침구(30)의 장착 및 분리가 용이하도록 한다.The work pipe 12 is connected to the power transmission device 10 including the engine and the oil tank, and the operating table 14 is installed at the tip of the working pipe 12, and the rotary shaft 16 of the operating table 14 is connected to the work pipe 12. Mounting the rotary blade body 20 is provided with a blade 22, but in the lower center of the rotary blade body 20 of the height that can be maintained by a certain height from the ground "
Figure 112005073863646-utm00003
"Type of support base 30 is installed, but the bottom of the support port 30 is formed in the base portion 32 is formed to be guided inclined to be guided inclined and the mounting plate 34 in the center of the coupling nut 36 The fixing nut is fixedly installed by screwing the coupling nut 36 to the rotating shaft part 16 in the opposite direction of rotation of the rotary blade body 20. The upper peripheral wall side of the support 30 may be held in a hexagonal cross section or by knurling. The gripping surface 38 can be formed to facilitate mounting and detachment of the support 30.

한편, 본 고안의 칼날회전체(20)에서는 받침구(30)의 상부장착판(32)외주면에 3개의 칼날(22)이 각각 핀연결된 구성으로 되어 있으나, 통상적으로 일자로 된 장방형 칼날의 중앙이 회전축부에 장착되어 사용되는 칼날회전체의 예초기에도 본 고안의 받침구가 적용될 수 있는 것이므로 이는 본 고안에서 한정하지 않는다.On the other hand, in the blade rotating body 20 of the present invention is composed of three blades 22 are pin-connected to the outer circumferential surface of the upper mounting plate 32 of the support 30, respectively, the center of the rectangular blade in the usual date Since the base of the present invention can also be applied to a lawnmower of the blade rotating body used to be mounted to the rotary shaft portion, this is not limited in the present invention.

이와 같이 된 본 고안은 엔진과 오일탱크가 내장된 동력전달장치(10)의 몸체를 등에 매고 동력전달장치와 연결된 작업파이프(12)선단에 설치된 회전칼날체(20)의 칼날(22)에 의해 예초작업을 하게 된다.The present invention as described above is attached to the body of the power transmission device 10, the engine and the oil tank is built on the back by the blade 22 of the rotary blade body 20 installed on the tip of the work pipe 12 connected to the power transmission device. We will work on mowing.

이때, 본 고안은 칼날회전체(20)의 하부중앙에 받침구(30)가 설치되어 칼날회전체(20)가 지면과 항상 일정높이만큼 유지되게 한상태에서 예초작업이 이루어지도록 하므로 칼날회전체(20)에 구비된 칼날(22)이 지면이나 잔돌에 닫지않고 예초작업을 할수 있게 됨과 아울러 균일하게 잡초를 밸수 있게 된다.At this time, the present invention is the blade rotation body (20) is installed in the lower center of the blade rotating body 20 so that the blade rotating body 20 is mowing work in the state that the blade rotating body 20 is always maintained by a certain height (blade rotating body ( The blade 22 provided in 20 can be mowed without being closed on the ground or rubble, and can weed uniformly.

또한, 작업자가 작업파이프(12)를 들더라도 칼날회전체(20)는 지면에서 일정높이를 유지하는 받침구(30)에 받쳐져서 미끌림이동하는 작업이 이루어지므로 어깨나 팔에 가해주는 하중을 크게 줄여 줄수 있게 된다.In addition, even if the worker lifts the work pipe 12, the blade rotating body 20 is supported by the support 30 to maintain a certain height on the ground, so that the sliding movement is made so that the load applied to the shoulder or arm is greatly increased. Can be reduced.

그리고 칼날회전체(20)하부의 받침구(30)외주면은 조립틈새나 조립홈등이 없고 매끄러운 형태로 되어 있으므로 이물질이 끼일 염려없이 사용할수 있고, 받침구(30)의 상부장착판(34)에 고정설치된 결합너트(36)에 의해 칼날회전체(20)의 장착기능도 함께 수행하고 그 구조도 간단한 것이다.And the outer circumferential surface of the support base 30 of the lower blade rotating body 20 has no assembly gaps or assembly grooves, so it can be used without fear of foreign matter being caught, and the upper mounting plate 34 of the support port 30 can be used. By the coupling nut 36 fixed to the mounting function of the blade rotating body 20 is also performed and its structure is simple.

이상에서 본 고안은 상기 구성실시예를 참고하여 설명하였지만 본 고안의 기술사상 범위내에서 다양한 변형실시가 가능함은 물론이다.Although the present invention has been described with reference to the above-described configuration embodiments, various modifications are possible within the technical spirit of the present invention.

이와 같이 본 고안의 예초기용 칼날회전체 받침구는 칼날회전체를 지면에서 일정높이로 유지한 상태로 예초작업을 할수 있게 되므로 칼날회전체에 구비된 칼날이 지면이나 잔돌이 닿아 손상되거나 파편등이 비상되어 안전사고가 발생하는 것을 방지할수 있고 작업자가 받침구에 의하여 칼날회전체를 미끌림 이동하여 작업할 수 있게 되므로 작업자의 팔이나 어깨의 하중을 크게 감소시켜 장시간 작업이 용이하며 균일한 높이로 잡초를 밸수 있게 된다.In this way, the blade rotating body support for the mowing device of the present invention is capable of mowing while maintaining the blade rotating body at a certain height from the ground, so that the blades provided on the blade rotating body are damaged or debris such as ground or rubble. It is possible to prevent the occurrence of safety accidents, and the operator can work by sliding the blade rotating body by the support hole, which greatly reduces the load on the arm or shoulder of the worker, making it easy to work for a long time and weeding at a uniform height. You can get it.

또한, 본 고안의 받침구는 그 구조가 간단하고 이물질이 끼일 염려가 없으므로 사용이 편리한 이점이 있다.In addition, the support port of the present invention has the advantage that the structure is simple and convenient to use because there is no fear of foreign matter being caught.
