Description

다목적 양손 예초기{LAWN TRIMMER}Multipurpose two-handed mower {LAWN TRIMMER}

본 발명은 다목적 양손 예초기에 관한 것으로서, 더욱 상세하게는 양손으로 핸들을 잡고 풀을 베는 방향으로 편리하게 움직이며 다양한 농기구를 결합하여 여러 가지 목적으로 사용할 수 있는 다목적 양손 예초기에 관한 것이다.The present invention relates to a multi-purpose two-handed mower, and more particularly, to a multi-purpose two-handed mower that can be used for various purposes by holding a handle with both hands and conveniently moving in the direction of mowing and combining various agricultural tools.

주지된 바와 같이, 예초기는 풀을 베는 데 사용하는 기계로서, 손으로 잡는 작업봉, 작업봉의 단부에 회전 가능하게 설치되어 풀을 베는 절삭날, 절삭날을 구동시키는 전동기를 포함한다.As is well known, a lawnmower is a machine used to cut grass, and includes a work rod held by hand, a cutting blade rotatably installed at an end of the work rod to cut grass, and an electric motor for driving the cutting blade.

일반적으로 예초기는 전동기를 어깨에 메고 작업봉을 손으로 잡은 상태에서 절삭날을 구동시켜서 풀을 벤다.In general, a lawnmower cuts grass by carrying a motor on the shoulder and driving the cutting edge while holding the work rod with the hand.

종래의 예초기는 풀 사이에 놓인 돌이나 날카로운 물체가 회전하는 절삭날에 걸리면서 주변으로 비산되어 작업자의 상해로 이어지는 문제점이 있었다.Conventional brush cutters have a problem in that stones or sharp objects placed between grass are caught on the rotating cutting blade and scattered around, leading to worker injury.

이러한 문제점을 해결하기 위한 종래기술로서, 대한민국 등록특허 제10-1393519호(등록일자 2014년05월02일) ‘예초기’ 및 대한민국 등록특허 제10-1160478호(등록일자 2012년06월21일) ‘모터 구동식 예초기’ 등이 개시되어 있다.As a prior art to solve these problems, Korean Patent Registration No. 10-1393519 (registration date: May 2, 2014) 'grass cutter' and Korean Patent Registration No. 10-1160478 (registration date: June 21, 2012) A 'motor-driven lawnmower' and the like are disclosed.

한편, 종래의 예초기는 무거운 전동기를 어깨에 메고 다니면서 풀을 베는 작업을 하므로 작업자가 쉽게 지치고 힘들어서 지속적인 작업을 진행하기 어려운 문제점이 있었다.On the other hand, since the conventional mower cuts grass while carrying a heavy electric motor on the shoulder, it is difficult for the operator to easily get tired and difficult to continue the work.

아울러, 종래의 예초기는 풀을 베는 하나의 기능만을 가지므로 흙을 복토하거나 갈아엎는 작업 또는 골을 파는 구굴 작업을 하는데 쓰이는 농기구를 결합하여 사용할 수 없어서 활용도가 떨어지는 문제점이 있었다.In addition, since the conventional mowing machine has only one function of cutting grass, it cannot be used in combination with agricultural tools used for soil covering or plowing work or gull work for digging valleys.

(0001) 대한민국 등록특허 제10-1393519호(등록일자 2014년05월02일)(0001) Republic of Korea Patent Registration No. 10-1393519 (registration date May 02, 2014) (0002) 대한민국 등록특허 제10-1160478호(등록일자 2012년06월21일)(0002) Republic of Korea Patent Registration No. 10-1160478 (registration date June 21, 2012) (0003) 대한민국 등록특허 제10-1734658호(등록일자 2017년05월02일)(0003) Republic of Korea Patent Registration No. 10-1734658 (registration date May 02, 2017) (0004) 대한민국 공개특허 제10-2010-0044149호(공개일자 2010년04월29일)(0004) Republic of Korea Patent Publication No. 10-2010-0044149 (published on April 29, 2010)

It is to provide a two-handed mower.

상기 목적을 달성하기 위해 본 발명은, 전동기의 구동으로 회전하는 절삭날에 의해 풀을 베는 다목적 양손 예초기에 있어서, 양손으로 파지하도록 손잡이가 양측에 연결된 핸들프레임 및 상기 핸들프레임의 하부에 연결되어 구동바퀴를 양측에 갖는 서포트프레임을 포함하는 프레임부재; 상기 프레임부재의 서포트프레임에 지지되는 전동기; 상기 전동기의 회전력으로 회전하도록 연결된 외측 단부에 스플라인을 갖는 구동축이 회전 가능하게 내장된 작동봉; 상기 작동봉의 외측 단부로 돌출된 상기 구동축의 스플라인에 분리 가능하게 결합되어 풀을 베는 절삭날; 및 상기 절삭날의 회전축 하부에 결합되어 돌 따위의 비산을 방지하는 안전판;을 포함하는 것을 기술사상으로 한다.In order to achieve the above object, the present invention provides a multi-purpose two-handed lawn mower that cuts grass by a cutting blade rotating by driving an electric motor, a handle frame connected to both sides so as to be gripped with both hands, and a handle frame connected to the lower portion of the handle frame to be driven. A frame member including a support frame having wheels on both sides; an electric motor supported by the support frame of the frame member; an operating rod rotatably embedded with a driving shaft having a spline at an outer end connected to rotate by the rotational force of the electric motor; a cutting blade that is detachably coupled to the spline of the drive shaft protruding from the outer end of the operating rod and cuts grass; And a safety plate coupled to the lower part of the rotating shaft of the cutting blade to prevent scattering of stones.

상기 핸들프레임의 후방에는 상기 구동축에 다른 농기구를 연결할 때에 상기 프레임부재를 바닥과 평행하게 지지하도록 보조바퀴가 구비될 수 있다.An auxiliary wheel may be provided at the rear of the handle frame to support the frame member in parallel with the floor when connecting other farming tools to the driving shaft.

이때, 상기 보조바퀴는 상기 핸들프레임의 후방에 길게 형성된 휠서포트로 연결될 수 있다.At this time, the auxiliary wheel may be connected to a wheel support formed long at the rear of the handle frame.

상기 절삭날이 분해된 상기 구동축의 스플라인에는 제초용 로터리가 결합될 수 있다.A weeding rotary may be coupled to the spline of the drive shaft from which the cutting blade is disassembled.

상기 절삭날이 분해된 상기 구동축의 스플라인에는 밭갈이용 로터리가 결합될 수 있다.A rotary for plowing may be coupled to the spline of the driving shaft in which the cutting blade is disassembled.

상기 절삭날이 분해된 상기 구동축의 스플라인에는 복토용 로터리가 결합될 수 있다.A rotary for covering soil may be coupled to the spline of the drive shaft from which the cutting blade is disassembled.

상술한 해결 수단으로 구현된 본 발명에 따르면, 양측 손잡이를 잡고 풀을 베는 방향으로 움직이면 구동바퀴가 회동하여 편리하게 이동하면서 안전판에 의해 돌 따위가 주변으로 비산되지 않도록 풀을 벨 수 있을 뿐만 아니라 절삭날이 분해된 구동축에 제초용 로터리, 밭갈이용 로터리, 복토용 로터리 따위의 농기구를 결합하여 다양한 용도로 작업을 할 수 있는 매우 유용한 효과가 있다.According to the present invention embodied in the above solution, when holding both handles and moving in the direction of mowing, the drive wheel rotates to conveniently move, and the safety plate not only cuts the grass so that stones are not scattered around, but also cuts the grass. Combining agricultural tools such as a rotary for weeding, a rotary for plowing, and a rotary for covering soil with the drive shaft with blades disassembled has a very useful effect that can work for various purposes.

즉, 제초용 로터리(R1)에는 보어(412)를 갖는 보스(411)를 구비하여 구동축(310)의 스플라인(311)에 네이브가 결합되므로, 전후 방향으로 회전하면서 잡초를 뽑아서 솎아내는 작업을 하는 것이다.That is, since the weeding rotary (R1) is provided with a boss 411 having a bore 412 and the nave is coupled to the spline 311 of the drive shaft 310, it rotates in the forward and backward directions to pull out and thin out weeds. will be.

다른 한편, 도 9는 본 발명의 또 다른 실시예에 의한 밭갈이용 로터리(R2)의 결합 상태를 나타낸 사시도이다.On the other hand, Figure 9 is a perspective view showing a coupling state of the rotary for plowing (R2) according to another embodiment of the present invention.

도 9를 참조하면, 절삭날(400)이 분해된 구동축(310)의 스플라인(311)에는 밭갈이용 로터리(R2)가 결합될 수 있다.Referring to FIG. 9 , a plowing rotary R2 may be coupled to the spline 311 of the driving shaft 310 from which the cutting blade 400 is disassembled.

즉, 밭갈이용 로터리(R2)에는 보어(412)를 갖는 보스(411)를 구비하여 구동축(310)의 스플라인(311)에 네이브가 결합되므로, 전후 방향으로 회전하면서 밭을 갈아엎는 작업을 하는 것이다.That is, since the plowing rotary R2 is provided with a boss 411 having a bore 412 and the nave is coupled to the spline 311 of the drive shaft 310, the work of plowing the field while rotating in the forward and backward directions is performed.

또 다른 한편, 도 10은 본 발명의 또 다른 실시예에 의한 복토용 로터리(R3)의 결합 상태를 나타낸 사시도이다.On the other hand, FIG. 10 is a perspective view showing a coupled state of the soil covering rotary R3 according to another embodiment of the present invention.

도 10을 참조하면, 절삭날(400)이 분해된 구동축(310)의 스플라인(311)에는 복토용 로터리(R3)가 결합될 수 있다.Referring to FIG. 10 , the soil covering rotary R3 may be coupled to the spline 311 of the driving shaft 310 from which the cutting blade 400 is disassembled.

즉, 복토용 로터리(R3)에는 보어(412)를 갖는 보스(411)를 구비하여 구동축(310)의 스플라인(311)에 네이브가 결합되므로, 전후 방향으로 회전하면서 밭을 갈아서 덮는 작업을 하는 것이다.That is, since the boss 411 having a bore 412 is provided in the soil-covering rotary R3 and the nave is coupled to the spline 311 of the drive shaft 310, the field is plowed and covered while rotating in the forward and backward directions.

상술한 본 발명의 실시예에 의하면, 양측 손잡이(111)를 잡고 풀을 베는 방향으로 움직이면 구동바퀴(121)가 회동하여 편리하게 이동하면서 안전판(500)에 의해 돌 따위가 주변으로 비산되지 않도록 풀을 벨 수 있을 뿐만 아니라 절삭날(400)이 분해된 구동축(310)에 제초용 로터리(R1), 밭갈이용 로터리(R2), 복토용 로터리(R3) 따위의 농기구를 결합하여 다양한 용도로 작업을 할 수 있는 장점이 있다.According to the embodiment of the present invention described above, when holding the handles 111 on both sides and moving in the direction of mowing, the driving wheel 121 rotates to conveniently move the grass so that stones are not scattered around by the safety plate 500. In addition, agricultural tools such as a weeding rotary (R1), a plowing rotary (R2), and a soil covering rotary (R3) can be combined with the drive shaft 310 with the cutting edge 400 disassembled to perform work for various purposes. There are advantages to doing so.
