Description
본 고안은 예초기에 관한 것으로, 특히 엔진본체와 아이들(Idle)하는 작업봉을 이용하여 회전커터를 자유자재로 기울임으로써 평지의 풀뿐만아니라 경사진 곳의 풀을 용이하게 깍거나 또는 정원수를 곡면으로 쉽게 다듬을 수 있도록 고안된 예초기에 관한 것이다.The present invention relates to a lawn mower, and in particular, by tilting the rotary cutter freely using the engine body and the idler (Idle), as well as the grass on the slope as well as the grass on the slope or the garden water to the curved surface It relates to a mower designed to be easily trimmed.
일반적으로, 예초기는 도1에 도시한 바와 같이 엔진본체(1)의 모터가 구동되면 작업봉(4)내의 샤프트가 회전되면서 커터판(9)을 회전시키게 되고, 동시에 커터판의 회전커터(10)가 회전되면서 풀을 자르도록 구성되어 있다.In general, the lawn mower rotates the cutter plate 9 while the shaft in the working rod 4 rotates when the motor of the engine body 1 is driven as shown in FIG. 1, and at the same time, the rotary cutter 10 of the cutter plate. ) Is configured to cut the grass as it rotates.
이때, 종래의 예초기는 도2에 도시한 바와 같이 엔진본체(1)에 고정 부착된 클러치케이스(3)의 선단부중 하부측이 축방향으로 절개되어 작업봉(4)이 클러치케이스의 선단부에 끼워지면 클램프볼트(14)를 클러치케이스와 작업봉에 지름방향으로 관통시켜 조립하고, 다시 클램프볼트(14-1)를 조여서 클러치케이스가 작업봉을조이도록 하여 고정시키게 된다.At this time, the conventional mowing machine as shown in Figure 2 of the lower end of the front end of the clutch case (3) fixedly attached to the engine body 1 is cut in the axial direction so that the working rod (4) is fitted to the front end of the clutch case The ground clamp bolt 14 is radially penetrated through the clutch case and the working rod, and the clamping bolt 14-1 is tightened to fix the clutch case by tightening the working rod.
따라서, 작업봉(4)을 중심축을 중심으로 회전시키게 되면 클러치케이스(3)와 함께 엔진본체(1)가 회전하게 된다.Accordingly, when the work rod 4 is rotated about the central axis, the engine body 1 rotates together with the clutch case 3.
여기서, 종래의 예초기는 묘 등과 같이 경사진 지면의 풀을 깎을 경우 커터판(10)을 경사진 면과 수평을 이루도록 조작하게 되는데, 이때 작업자는 작업핸들(7)을 이용하여 작업봉(4)을 회전시킴으로써 커터판을 경사지면과 수평을 이루도록 한다.Here, when cutting the grass of the inclined ground such as seedlings, the conventional mowing machine is operated to make the cutter plate 10 to be in parallel with the inclined surface, the worker using the work handle (7) working rod (4) Rotate the cutter plate so that it is level with the inclined surface.
그러나, 종래의 예초기는 작업봉(4)을 회전시키면 클러치케이스(3)와 함께 엔진본체(1)가 회전되면서 엔진본체의 상부에 설치된 연료통(2)이 한쪽으로 기울어지고, 동시에 연료통내의 연료가 한쪽으로 쏠리면서 엔진본체로의 연료공급이 중단되어 엔진본체내의 모터작동을 정지시키는 경우가 발생된다.However, in the conventional mower, when the working rod 4 is rotated, the engine body 1 is rotated together with the clutch case 3 while the fuel tank 2 installed on the upper part of the engine body is inclined to one side, and at the same time, the fuel in the fuel container is discharged. The fuel supply to the engine main body is stopped while being pulled to one side to stop the motor operation in the engine main body.
또한, 종래의 예초기는 작업봉(4)이 중량의 엔진본체(1)와 함께 회전되기 때문에 작업봉을 회전시키거나 작업중 작업봉의 회전상태를 그대로 유지시킬 때 과다한 힘이 요구되고, 이로써 작업자의 피로를 가중시키어 작업의 생산성을 저하시키는 문제점이 있다.In addition, in the conventional mowing machine, since the working rod 4 is rotated together with the engine body 1 of heavy weight, excessive force is required when rotating the working rod or maintaining the rotating state of the working rod during operation. There is a problem of lowering the productivity of the work by weighting.
더욱이, 종래의 예초기는 멜방(13-1)을 거는 멜방고리(12-1)가 작업봉(4)에 고정되어 있어 작업봉의 회전시 작업자의 어깨에 메는 멜방(13-1)도 함께 돌아가게 되어 작업에 불편을 초래하게 된다.In addition, the conventional mowing machine is fixed to the working rod (4), the melody ring (12-1) hanging the melody (13-1) so that the buckles (13-1) to be carried on the shoulder of the worker when the working rod is rotated together This causes inconvenience to work.
그리고, 종래의 예초기에는 그 보관시 작업봉(4)의 수평을 유지하기 위한 별도의 스탠드가 없거나 스탠드가 엔진본체(1)에 장착되어 있는데, 이때 엔진본체에 스탠드가 장착된 경우 엔진파손의 우려가 있고, 엔진본체내의 플러그교환시 그 분해조립을 방해하게 된다.In addition, in the conventional mowing machine, there is no separate stand for keeping the working rod 4 horizontal when it is stored, or the stand is mounted on the engine main body 1. At this time, if the stand is mounted on the engine main body, the engine may be damaged. This prevents the disassembly and assembly of the plug in the engine body.
본 고안은 작업봉이 클러치케이스에 회전 가능하도록 결합되어 작업봉의 회전시 엔진본체와 아이들(Idle)함으로써 연료공급중단에 따른 엔진본체내의 모터정지를 방지하고, 작업봉의 회전시 작업자의 피로를 경감시킬 수 있는 예초기를 제공함에 그 목적이 있다.The present invention can be coupled to the clutch case rotatable to prevent the motor stop in the engine body due to fuel supply interruption by idle the engine body and idle (Idle) when the working rod rotates, can reduce the fatigue of the operator when the working rod is rotated The purpose is to provide a mower.

도면을 참조하여 본 고안의 구성을 설명한다.The configuration of the present invention will be described with reference to the drawings.
도3은 본 고안에 따른 예초기를 나타내는 사시도이고, 도4는 본 고안에 따른 예초기중 작업봉과 클러치케이스의 결합상태를 나타내는 단면도이다.Figure 3 is a perspective view showing a lawn mower according to the present invention, Figure 4 is a cross-sectional view showing a coupling state of the working rod and the clutch case in the lawn mower according to the present invention.
엔진본체(1)에 다수의 볼트에 의해 고정 부착되는 본 고안의 클러치케이스(23)는 종래의 클러치케이스(3)와 달리 작업봉(24)을 삽입하는 선단부가 절개되지 않은 일체형으로 형성되어 있다.Clutch case 23 of the present invention is fixedly attached to the engine body 1 by a plurality of bolts, unlike the conventional clutch case (3) is formed in a one-piece not distal end portion for inserting the working rod 24. .
이때, 작업봉(24)에는 클러치케이스(23)에 삽입되는 그 외주면에 슬리브(17)가 리벳이음에 의해 고정적으로 끼워져 있고, 이 슬리브(17)는 그 외주면이 클러치케이스(23)의 내주면과 일정한 간격의 클리어런스(Clearance)를 유지하면서 작업봉과 함께 공회전을 하게 된다.At this time, the sleeve 17 is fixedly fitted to the working rod 24 by the rivet joint on its outer circumferential surface, which is inserted into the clutch case 23, and the outer circumferential surface of the sleeve 17 is the inner circumferential surface of the clutch case 23. It idles with the rod while maintaining a constant clearance.
그리고, 슬리브(17)가 끼워지는 작업봉(24)의 선단부를 클러치케이스(23)에 끼우면 작업봉(24)의 선단면이 단턱(23-3)에 걸려 더이상 진행되지 않게 된다.Then, when the front end portion of the working rod 24 into which the sleeve 17 is fitted is inserted into the clutch case 23, the front end surface of the working rod 24 is caught by the step 23-3 and no longer proceeds.
이렇개 결합된 상태에서 와셔(21)를 작업봉(24)을 따라 단턱(23-2)에 걸려 더이상 진행되지 않을 때까지 클러치케이스(23)의 내주면으로 밀어 넣어 결합시키게 된다.In such a coupled state, the washer 21 is engaged by pushing the inner circumferential surface of the clutch case 23 until it stops on the step 23-2 along the working rod 24.
여기서, 스냅링(Snap Ring)(22)을 장력을 이용하여 요홈(23-1)에 끼워 넣으면 와셔(21)가 단턱(23-2)과 스냅링에 걸리면서 클러치케이스(23)로부터 작업봉(24)의 이탈을 차단하게 된다.Here, when the snap ring 22 is inserted into the groove 23-1 by using tension, the washer 21 is caught by the step 23-2 and the snap ring, and the work rod 24 is removed from the clutch case 23. Will block the departure.
즉, 작업봉(24)의 회전중 슬리브(20)는 와셔(21)와 단턱(23-3)에 의해 축방향 유동이 고정되고, 와셔(21)는 단턱(23-2)과 스냅링(22) 사이에 고정되어 클러치케이스(23)로부터 작업봉이 이탈되는 현상을 방지하게 된다.That is, the sleeve 20 during rotation of the working rod 24 is fixed in the axial flow by the washer 21 and step 23-3, the washer 21 is stepped 23-2 and the snap ring 22 It is fixed between the) to prevent the phenomenon that the working rod is separated from the clutch case (23).
한편, 본 고안에서는 클러치케이스(23)의 외측면에 고정블록(23-4)이 서로 대칭되도록 설치 형성되어 있고, 이 고정블록(23-4)의 홈에 스탠드(25)의 상단부가 장탈착이 가능하도록 끼워지게 된다.On the other hand, in the present invention, the fixing block 23-4 is formed on the outer surface of the clutch case 23 so as to be symmetrical with each other, the upper end of the stand 25 in the groove of the fixing block 23-4 is demountable Is fitted to make this possible.
따라서, 예초기의 보관시 작업봉(24)은 커터커버(8)와 스탠드(25)에 의해 지지되어 그 수평을 유지하게 된다.Therefore, the working rod 24 is supported by the cutter cover 8 and the stand 25 when the lawn mower is stored to keep its horizontal.
그리고, 본 고안에 따른 예초기에는 멜방걸이(12)가 클러치케이스(23)의 상부에 고정 부착되어 작업봉(24)의 회전시에도 멜방(13)이 돌아가는 현상을 방지하게 된다.In addition, in the lawn mower according to the present invention, the melter hanger 12 is fixedly attached to the upper portion of the clutch case 23 to prevent the melter 13 from rotating even when the working rod 24 is rotated.
이하, 본 고안의 작용을 설명한다.Hereinafter, the operation of the present invention.
멜방(13)을 이용하여 예초기를 어깨에 짊어진 상태에서 작업핸들(7)을 잡고서 풀깎는 작업을 실시하던중 작업봉(24)을 회전시킬 경우 엔진본체(1)는 고정된 상태에서 작업봉이 클러치케이스(23)내에서 공회전되어 커터판(9)을 원하는 각도로 회전시키게 된다.When the working rod 24 is rotated while the working handle 7 is being grasped while the mowing machine is carried on the shoulder using the melter 13, the engine body 1 is fixed while the working rod is clutched. It is idle in the case 23 to rotate the cutter plate 9 at a desired angle.
이때, 슬리브(20)는 와셔(21)와 단턱(23-3)에 의해 축방향 유동이 고정되면서 와셔(21)는 단턱(23-2)과 스냅링(22) 사이에 고정되어 작업봉(24)이 회전중 클러치케이스(23)로부터 분리되는 현상을 방지하게 된다.At this time, while the sleeve 20 is fixed in the axial flow by the washer 21 and the step 23-3, the washer 21 is fixed between the step 23-2 and the snap ring 22, working rod 24 ) Is prevented from being separated from the clutch case 23 during rotation.
따라서, 본 고안에 따른 예초기는 작업봉(24)이 엔진본체(1)와 분리된 상태에서 공회전되기 때문에 종래의 예초기와 달리 작업봉의 회전작업이 힘들지 않고 간단하다.Therefore, the lawn mower according to the present invention is simple, since the working rod 24 is idle in the state separated from the engine main body 1, unlike the conventional mower.
또한, 엔진본체(1)는 항상 중력방향으로 고정되어 있어 연료통(2)의 연료가 한쪽으로 기울어지는 현상이 일어나지 않고, 이로부터 풀깎는 작업중 연료공급중단에 따른 엔진본체내의 모터가 정지되는 문제는 발생되지 않게 된다.In addition, the engine main body 1 is always fixed in the direction of gravity so that the fuel in the fuel tank 2 does not incline to one side, and there is a problem that the motor in the engine main body is stopped due to the fuel supply interruption during the pulling operation. It will not occur.
한편, 작업봉(24)의 회전시 멜방(13)이 돌아가지 않기 때문에 효율적으로 작업을 수행할 수 있고, 예초기의 보관시 스탠드(25)를 고정블록(23-4)에 끼우게 되면 작업봉(24)은 커터커버(8)와 스탠드(25)에 의해 수평 지지되어 그 변형을 방지하게 된다.On the other hand, since the melbang 13 does not rotate when the working rod 24 is rotated, the work can be efficiently performed, and when the stand 25 is inserted into the fixing block 23-4 during storage of the lawn mower, the working rod 24 is horizontally supported by the cutter cover 8 and the stand 25 to prevent deformation thereof.
더욱이, 스탠드(25)의 경우 클러치케이스(23)에 장착되어 엔진플러그의 교환시 장애가 되지 않게 된다.In addition, the stand 25 is mounted on the clutch case 23 so that the engine plug is not obstructed when the engine plug is replaced.
본 고안은 작업봉이 클러치케이스에 회전 가능하도록 결합되어 작업봉의 회전시 엔진본체와 아이들(Idle)함으로써 연료공급중단에 따른 엔진본체내의 모터정지를 방지하고, 작업봉의 회전시 작업자의 피로를 경감시킬 수 있는 효과를 제공한다.The present invention can be coupled to the clutch case rotatable to prevent the motor stop in the engine body due to fuel supply interruption by idle the engine body and idle (Idle) when the working rod rotates, can reduce the fatigue of the operator when the working rod is rotated Provide the effect.
