본 발명은 승용이앙기의 동력전달축 연결구조에 관한 것으로, 이앙기의 본기에 부착하여 사용하는 이앙장치나 직파장치의 착·탈이 용이하면서도, 작업인원이 절감되도록 된 승용이앙기의 동력전달축 연결구조에 관한 것이다.The present invention relates to a power transmission shaft connecting structure of a passenger rice transplanter, while the attachment and detachment of a rice transplanter or a straight wave device attached to the rice transplanter is easy to use, while the power transmission shaft connection structure of a passenger rice transplanter to reduce the number of workers. It is about.
일반적으로 승용이앙기는 엔진의 동력을 전달받아 트랜스미션을 거쳐, 이앙축으로부터 추진축을 거쳐 연결축을 통해 이앙장치로 전달되며, 이앙장치의 이앙암을 회전시키며 동시에 묘탑재대를 좌·우 왕복운동시켜 이앙작업을 하거나, 또는 직파장치가 부착된 경우에는 상기 엔진의 동력을 전달받아 트랜스미션을 거쳐 이앙축으로부터 추진축과 연결축을 거쳐 직파장치의 감소기, 구동체인 및 조출장치를 통해 직파작업을 할 수 있도록 되어 있다.In general, passenger rice transplanters receive power from the engine and are transferred to the rice transplanter through the transmission shaft from the rice transplant shaft through the transmission shaft, and then through the connecting shaft. Or, if a direct wave device is attached, the engine receives power from the transfer shaft and passes through the propulsion shaft and the connecting shaft to perform the straight wave operation through the reducer, drive chain and feeding device of the direct wave device. .
위와 같은 이앙장치와 직파장치등을 작동시키기 위한 동력전달축은 제3도에 도시된 바와 같이, 이앙축에 연결되는 연결부(103)에 이어진 원통형의 몸체(102)와, 이와 반대쪽 몸체(102)의 내부에 스플라인(105)이 형성된 삽입홀(104)을 갖춘 추진축(101)과; 이 추진축(101)의 삽입홀(104)에 결합되면서 연결축에 고정되는 종동축(106)로 구성되어져 있다.As shown in FIG. 3, the power transmission shaft for operating the rice transplanter and the wave directing device as described above has a cylindrical body 102 connected to the connecting portion 103 connected to the rice transplanter, and the opposite body 102. A propulsion shaft 101 having an insertion hole 104 having a spline 105 formed therein; It is composed of a driven shaft 106 is coupled to the insertion hole 104 of the propulsion shaft 101 and fixed to the connecting shaft.
여기서, 상기 종동축(106)은 원통형몸체(107)의 2/3 길이 정도 외주면을 따라 형성된 스플라인(110)과, 이와 반대쪽 몸체(107)에 이어진 연결부(108)로 이루어져 있다.Here, the driven shaft 106 is composed of a spline 110 formed along an outer circumferential surface of about 2/3 of the cylindrical body 107, and a connecting portion 108 connected to the opposite body 107.
따라서, 엔진의 동력이 이앙축으로 전달되면서 상기 이앙축에 연결부(103)을 매개로 고정된 추진축(101)에 회전력이 전달되어, 상기 추진축(101)에 스플라인 결합된 종동축(106)을 매개로 이 종동축(106)의 연결부(108)에 고정된 연결축으로 회전력이 전달되어 이앙장치나 직파장치등을 작동시키게 된다.Accordingly, while the power of the engine is transmitted to the moving axis, rotational force is transmitted to the propulsion shaft 101 fixed to the moving shaft via the connecting portion 103, and the driven shaft 106 is splined to the driving shaft 101. As a result, the rotational force is transmitted to the connecting shaft fixed to the connecting portion 108 of the driven shaft 106 to operate the rice transplanter or the direct wave device.
그러나 이와같이 상기 이앙축의 회전력을 연결부로 전달시키는 동력전달축인 추진축(101)과 종동축(106)이 단순하게 스플라인 결합되어 회전력을 전달하게 하면, 이앙작업과 직파자업에 따라 선택적으로 이앙장치와 직파장치를 착탈시킬 경우, 상기 추진축(101)과 종동축(106)의 결합거리(P-P')가 변화하지 않은 상태에서 상호 착탈하지 못하는 구조이므로, 상기 이앙장치와 직파장치가 추진축(101)과 종동축(106)에 결합된 상태에서 이앙축과 추진축(101)을 부착하고 분리하지 않으면 안되므로 필요이상의 작업인원이 필요하고, 추진축(101)과 종동축(106) 연결시 타이밍 마크를 맞추지 않고 조립하였을 경우에 이를 다시 분해하여 조립해야만 될 뿐만 아니라, 이앙장치 또는 직파장치를 이앙기 본기에 부착하는 경우 링크(도시되어 있지 않음)등을 개재하여 부착하게 되는데, 이때 링크부착시, 상기 추진축(101)과 종동축(106)을 동시에 스플라인 연결하여 부착해야만 하므로 작업이 용이하지 않게 되는 문제점이 있었다.However, when the propulsion shaft 101 and the driven shaft 106, which are the power transmission shafts for transmitting the rotational force of the transfer shaft to the connecting portion, are simply splined to transmit the rotational force, according to the transfer operation and the straight-line operation, the transfer apparatus and the straight wave are selectively When detaching the device, since the coupling distance (P-P ') of the propulsion shaft 101 and the driven shaft 106 does not change with each other in a structure that does not change, the rice transplanter and the direct wave device is the propulsion shaft 101 And the moving shaft and the propulsion shaft 101 must be attached and separated in the state coupled to the driven shaft 106, so that more work is required than necessary, and the timing marks are not aligned when the propulsion shaft 101 and the driven shaft 106 are connected. When assembled, not only must they be disassembled and assembled again, but also when attaching a rice transplanter or a wave directing device to a rice transplanter, via a link (not shown). At this time, when the link is attached, the propulsion shaft 101 and the driven shaft 106 must be attached by spline connection at the same time, there is a problem that the operation is not easy.
이에 본 발명은 상기와 같은 문제점을 해소하기 위해 발명된 것으로, 승용이앙기의 본기 뒤쪽에 링크를 개재시켜 이앙장치 또는 직파장치가 연결되어 직파작업을 할 경우에는 , 이앙기 본기에서 이앙장치를 분리한 후 직파장치를 부착하여 작업을 하고, 이앙작어 할 경우에는, 이앙기 본기에서 직파장치를 분리한 후 이앙장치를 부착하여 작업을 하게 되므로 이때, 중간축을 매개로 추진축과 종동축이 결합되어 상기 추진축과 종동축의 결합거리(P-P')가 변화하지 않더라도 이앙장치나 직파장치의 착·탈시, 추진축과 중간축의 스플라인 결합부위가 신·축가능하도록 구성되어 상기 이앙장치나 직파장치의 착·탈이 용이하도록 된 승용이앙기의 동력전달축 연결구조를 제공함에 그 목적이 있다.Therefore, the present invention was invented to solve the above problems, when a rice transplanter or a direct wave device is connected via a link to the rear of the main rice transplanter when the straight wave work, after separating the rice transplanter from the rice transplanter main body In the case of attaching a straight wave device, and in the case of a rice transplanter, since the straight wave device is removed from the rice transplanter and the rice transplanter is attached, the propulsion shaft and the driven shaft are coupled to each other through the intermediate shaft. Even when the coaxial coupling distance (P-P ') does not change, the spline coupling portion between the propulsion shaft and the intermediate shaft can be expanded and contracted even when the coupling device or the linear wave device is not changed. It is an object of the present invention to provide a power transmission shaft connection structure of a passenger transplanter that is made easy.
상기와 같은 목적을 달성하기 위한 본 발명은, 이앙축에 연결되는 연결부와, 이 연결부에 이어진 원형의 몸체 및 이와 반대부위의 몸체에 외주면에 스플라인을 갖춘 삽입부로 이루어진 추진축과; 선단부위에 스냅링을 갖춘 삽입부와, 이 삽입부에 동심원으로 이어진 몸체 및 이와 반대부위의 몸체에 이어져 연결축에고정되는 연결부로 이루어진 종동축이; 내홈과, 이 내홈을 따라 형성된 스플라인을 갖춘 원형의 몸체로 이루어진 중간축을 매개로 상호 결합되고, 상기 종동축에 의해 연결된 중간축과 연결축 사이에는 스프링이 삽입되어 커버에 의해 감싸져 있는 구조로 되어 있다.The present invention for achieving the above object, the connecting portion is connected to the axis of the axis, and the propulsion shaft consisting of a circular body connected to the connecting portion and the insertion portion having a spline on the outer circumferential surface on the opposite side; A driven shaft comprising a snap portion at the distal end and a connecting portion fixed to the coupling shaft by a body concentrically connected to the insert portion and a body opposite thereto; The inner groove and the intermediate shaft consisting of a circular body having a spline formed along the inner groove are connected to each other by a medium, the spring is inserted between the intermediate shaft and the connecting shaft connected by the driven shaft is wrapped around the cover have.
이하 본 발명을 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제2도는 본 발명에 따른 동력전달축 연결구조의 전달면도를 도시한 것인바, 내흠(13)과, 이 내흠(13)을 따라 어느정도 깊이로 스플라인(14)이 형성된 원통형의 몸체(12)를 갖춘 중간축(11)을 매개로, 이앙축에 연결되는 추진축(1)과, 연결축에 연결되는 종동축(6)이 상호 결합되는데, 상기 추진축(1)에는 이앙축에 연결되는 연결부(3)와, 이 연결부(3)에 이어진 원통형의 몸체(2) 및 이와 반대쪽 몸체(2)의 외주면에 스플라인(5)이 형성되어 중간측(11)의 스플라인(14)과 결합되는 삽입부(4)가 갖추어지고, 상기 종동축(6)에는 중간축(11)의 내흠(13)에 삽입되면서 선단부위에 스냅링(15)를 갖춘 삽입부(9)와, 이 삽입부(9)에 동심원으로 이어진 몸체(7) 및, 이와 반대쪽 몸체(7)에 이어져 연결축에 고정되는 연결부(8)가 갖추어져 있다.Figure 2 shows a transmission side view of the power transmission shaft connecting structure according to the present invention, the inner flaw 13 and the cylindrical body 12, the spline 14 is formed to a certain depth along the inner flaw (13) The intermediate shaft 11 is provided as a medium, and the driving shaft 1 connected to the moving shaft and the driven shaft 6 connected to the connecting shaft are coupled to each other, and the driving shaft 1 is connected to the moving shaft 3. And an insertion portion 4 formed with a spline 5 on the outer circumferential surface of the cylindrical body 2 connected to the connecting portion 3 and the opposite body 2 and engaged with the spline 14 on the intermediate side 11. Is inserted into the inner shaft (13) of the intermediate shaft (11), and has an insertion portion (9) having a snap ring (15) at the distal end portion, and the insertion portion (9) is concentrically connected to the driven shaft (6). It is provided with a connecting portion 8 which is connected to the body 7 and to the opposite body 7 and fixed to the connecting shaft.
또한 상기 종동축(6)에 의해 연결된 중간축(11)과 연결축 사이에는 스프링(16)이 삽입되어 주름진 커버(17)에 의해 감싸지게 된다.In addition, the spring 16 is inserted between the intermediate shaft 11 and the connecting shaft connected by the driven shaft 6 to be wrapped by the corrugated cover 17.
따라서, 엔진의 동력이 이앙축으로 전달되면서 상기 이앙축에 연결부(3)를 매개로 고정된 추진축(1)에 회전되어 전달되어, 상기 추진축(1)에 스플라인 결합된 중간축(11)을 통해 연결축에 연결된 종동축(6)으로 회전력이 전달되고 이에 따라, 상기 연결축을 매개로 이앙장치나 직파장치가 작동되게 된다.Accordingly, while the power of the engine is transmitted to the moving axis, the engine is rotated and transmitted to the propulsion shaft 1 fixed through the connection part 3 to the moving axis, and is splined to the driving shaft 1 through the intermediate shaft 11. The rotational force is transmitted to the driven shaft 6 connected to the connecting shaft, whereby the rice transplanter or the wave directing device is operated through the connecting shaft.
또한, 필요에 따라 선택적으로 이앙장치나 직파장치를 분리할 경우에는, 상기 종동축(6)의 외주면에 삽입되어 중간축(11)을 추진축(1)쪽으로 일정하게 힘을 가한느 스프링(16)을 상기 중간축(11)을 추진축(1)쪽으로 일정하게 힘을 가하는 스프링(16)을 상기 중간축(11)을 이용하여 압축시키게 되면 스플라인 결합된 추진축(1)이 분리되는 한편, 이앙장치나 직파장치를 결합할 경우에는, 먼저 이앙장치, 직파장치를 링크를 매개로 연결한 후, 상기 스프링(16)을 압축시켜 중간축(11)을 추진축(1)의 삽입부(4)에 위치시킨 다음 스플라인 결합하게 되면, 상기 스프링(16)에 의해 추진축(1)에는 일정한 힘이 작용되어 결합을 강화시키게 된다.In addition, when the separation device or the wave directing device is selectively removed as necessary, the spring 16 is inserted into the outer circumferential surface of the driven shaft 6 and constantly applies the intermediate shaft 11 toward the propulsion shaft 1. When the spring 16 is applied to the intermediate shaft 11 to the propulsion shaft 1 by a constant force to the compression using the intermediate shaft 11, the spline-coupled propulsion shaft 1 is separated, In the case of combining the direct wave device, first, the linking device is connected to the direct wave device and the direct wave device, and then the spring 16 is compressed to position the intermediate shaft 11 at the insertion portion 4 of the propulsion shaft 1. When the next spline coupling, a constant force is applied to the propulsion shaft (1) by the spring 16 to strengthen the coupling.
그리고, 상기 종동축(6)의 삽입부(9)에 체결된 스냅링(15)에 의해 착·탈시 상기 종동축(6)과 중간축(11)의 이탈이 방지된다.In addition, the detachment of the driven shaft 6 and the intermediate shaft 11 is prevented by the snap ring 15 fastened to the insertion portion 9 of the driven shaft 6.
이상 설명한 바와 같이 본 발명에 의하면, 추진축과 종동축이 중간축을 매개로 연결되고, 상기 중간축(11)과 종동축(6)의 결합거리가 스프링의 신·축에 의해 조절되어 이앙장치나 직파장치의 착·탈이 용이하여 작업인원을 절감할 뿐만 아니라, 상기 스프링에 의해 추진축에 일정한 힘이 작용하게 되어 상기 추진축과 중간축의 결합력이 향상되고, 상기 추진축과 종동축의 연결시 타이밍 마크를 정확히 일치시키기가 용이하게 되는 효과가 있다.As described above, according to the present invention, the propulsion shaft and the driven shaft are connected via the intermediate shaft, and the coupling distance between the intermediate shaft 11 and the driven shaft 6 is adjusted by the expansion and contraction of the spring to move the rice transplanter or the straight wave. It is easy to attach and detach the device, which not only reduces the number of people, but also by the spring, a constant force is applied to the propulsion shaft to improve the coupling force between the propulsion shaft and the intermediate shaft, and accurately adjust the timing marks when the propulsion shaft and the driven shaft are connected. There is an effect that it is easy to match.
