본 고안은 핸들의 방향전환에 따라 변속레버의 방향변경이 용이한 보행형 관리기의 방향전환이 가능한 변속레버에 관한 것이다.The present invention relates to a shift lever capable of changing the direction of the walking type manager easy to change the direction of the shift lever in accordance with the direction of the handle.

일반적으로 관리기는 다양한 작업기를 취부하여 다목적으로 작업할 수 있도록한 농업기계의 일종이다.In general, the manager is a kind of agricultural machine that can be used for multi-purpose work by attaching various work machines.

따라서 관리기는 전후부위에 작업기를 부착하여 작업하는바, 부착방향이나 운전조작의 위치에 따라, 핸들이 360°상에서 자유자재로 전환할 수 있도록 되어 있다.Therefore, the manager works by attaching the work machine to the front and rear parts, and the handle can be freely switched over 360 ° according to the attachment direction and the position of the driving operation.

그런데 종래에는 변속장치의 난제로 인하여 변속레버가 고정식으로 장착되어 있어서 핸들의 방향이 변하더라도 변속레버의 방향이 변하지 않으므로서 작업상의 불편한 문제점이 있었을 뿐 아니라 작업능률이 저하되는 요인이 있다.However, in the related art, the shift lever is fixedly mounted due to the difficulty of the shifting device, and thus the direction of the shift lever does not change even if the direction of the handle is changed.

따라서 본 고안의 상기의 종래의 문제점을 해결하기 위하여 안출된 것으로서 미션외부에 변속포크를 개설하고 레버부를 세레이션 가공하여 조립하여 작업자의 핸들의 위치에 따라 임의의 선택방향에서 변속레버를 임의의 방향으로 전환사용할수 있도록 함이 목적이다.Therefore, in order to solve the above-mentioned conventional problems of the present invention, a shift fork is opened outside the mission, and a serration is processed by assembling the lever part to shift the shift lever in an arbitrary selection direction according to the position of the operator's handle. The purpose is to make it available for conversion.

본 고안은 상기의 목적을 달성하기 위하여 본 고안을 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.The present invention is described in detail based on the accompanying drawings to achieve the above object is as follows.

제 1 도에서 제 3 도에 도시된 바와 같이 통상의 보행형관리기(1)의 상부 일측에 장착되어 있는 주변속레버(2)에 있어서, 손잡이(3)가 나착된 주변속레버(2)에 용접된 통형체(4)에 있어서, 내측저면에 스플라인부(7')를 형성하며 그 내부에 스프링(5)을 내장하여 일부에 스플라인부(7)가 형설된축(6)을 축지하고 기체에 레버조합을 고정할 브라켓트(8)를 통형체(4)하부에 형설하며 브라켓트(8) 내측으로는 변속포크(10)(10')를 조작해줄 아암(9)을 내설하되 아암(9)상부의 내주연에 축(6)의 일부에 형성된 스플라인부(7)와 일치되도록 스프라인부(7")를 형성하여 결합하며 축(6)의 저면부와 아암(9)사이에 형설된 내부공간은 간격통(11)으로 지지하고 평와셔(12)로 막은 다음 볼트(13)로 체결하여 구성된 것이다.As shown in FIG. 1 to FIG. 3, in the peripheral speed lever 2 mounted on the upper side of the conventional walking type manager 1, the peripheral speed lever 2 to which the handle 3 is attached is attached. In the welded cylindrical body 4, a spline portion 7 'is formed on the inner bottom and a spring 5 is embedded therein to hold the shaft 6 on which a spline portion 7 is formed. A bracket (8) for fixing the lever combination to the lower part of the cylindrical body (4) and an arm (9) for operating the shifting forks (10) and (10 ') inside the bracket (8). Inner portion formed at the inner circumference of the upper portion to form a spline portion 7 "so as to coincide with the spline portion 7 formed on a part of the shaft 6 and formed between the bottom portion of the shaft 6 and the arm 9 The space is supported by the spacer 11, closed with a flat washer 12, and then fastened with a bolt 13.

이와 같은 본 고안의 구성은 축(6)의 스플라인부(7)에 주변속레버(2)가 용접된 통형체(4) 내측의 스플라인부(7')와 아암(9)상부의 스플라인부(7")가 축(6)의 일부에 형성된 스플라인부(7)에 세레이션으로 맞물린 상태가 되도록 축(6)을 축지하여 손잡이(3)가 나착된 주변속레버(2)를 작동하면 각각의 스플라인부(7)(7')(7")가 세레이션으로 맞물려 있으므로서 아암(9)도 동시에 작동하게 되므로서 아암(9)이 변속포크(10)(10')를 조작하여 주는 것이며 또한 주변속레버(2)를 핸들의 위치에 따라 임의의 방향으로 전환시키고 저 할 때에는 손잡이(3)가 나착된 주변속레버(2)를 상부로 들어올리면 주변속레버(2)에 용접된 통형체(4)가 스프링(5)을 압축하면서 축(6)에 형성된 단부까지 통형체(4)가 올라가면서 축(6)의 일부에 형성된 스플라인부(7)와 통형체(4) 내측 하부에 형성된 스플라인부(7')가 이탈되므로서 방향전환이 임의의 방향으로 전환되는 것이다.The configuration of the present invention is such that the spline portion 7 ′ inside the cylindrical body 4 in which the peripheral speed lever 2 is welded to the spline portion 7 of the shaft 6 and the spline portion of the upper portion of the arm 9 ( When the 7 ") is engaged with the spline portion 7 formed in a part of the shaft 6 in a serration state, the shaft 6 is driven to operate the peripheral speed lever 2 to which the handle 3 is attached. As the splines 7, 7 ′ and 7 ″ are engaged by serrations, the arm 9 is also operated at the same time so that the arm 9 operates the shifting forks 10 and 10 ′. Switch the peripheral speed lever 2 in an arbitrary direction according to the position of the handle, and when lowering the cylindrical body welded to the peripheral speed lever 2 by lifting the peripheral speed lever 2 with the handle 3 attached thereon. (4) is formed in the lower portion of the spline portion 7 and the cylindrical body 4 formed in a part of the shaft 6 as the cylindrical body 4 ascends to the end formed in the shaft 6 while compressing the spring (5) As the spline portion 7 'is detached, the change of direction is switched in an arbitrary direction.

이와 같이 작업자가 원하는 임의의 방향에서 손잡이(3)가 나착된 주변속레버(2)를 놓게 되면 압축되었던 스프링(5)이 정상위치로 환원되어 통형체(4)가 하향되면서 각각의 스플라인부(7)(7')(7")가 접촉되어 변속이 가능하게 되는 것이다.In this way, when the operator releases the peripheral speed lever 2 to which the handle 3 is attached in any desired direction, the spring 5 that has been compressed is reduced to the normal position and the cylindrical body 4 is downward, and each spline part ( 7) (7 ') (7 ") are in contact to allow shifting.

이상 설명한 바와 같이 핸들의 방향에 따라 주변속레버를 방향전환하여 조작하므로서 종래의 고정식으로 되어 있어 핸들의 방향전환 하였을때 작업도중 주변속레버를 조작하려면 정지시키고 변속레버의 위치까지 작업자가 이동하여 조작하던 것을 작업자의 조작하기 편리한 위치에 셋트시키고 조작하므로서 주변속레버의 조작 간편화 및 작업능률을 향상시키는 유용한 고안이다.As described above, the peripheral speed lever is operated by changing the direction of the peripheral speed lever according to the direction of the handle. Thus, when the direction of the handle is changed, to operate the peripheral speed lever during operation, the operator stops and the operator moves to the position of the transmission lever. It is a useful design to simplify the operation and improve the work efficiency of the peripheral speed lever by setting and manipulating it in a convenient location for the operator.
