本考案は、運転座席の前方に左右揺動自在に走
行用変速機構に連係された操作レバーを設けた乗
用型田植機や乗用型耕耘機等の乗用型移動農機の
変速操作装置に関する。[Detailed description of the invention] The present invention is applicable to riding mobile agricultural machines such as riding rice transplanters and riding tillers, which have an operating lever in front of the driver's seat that is linked to a traveling transmission mechanism and can swing left and right. The present invention relates to a speed change operation device.

時等において迅速に操作できないおそれがあつ
た。 The above-mentioned speed change operation device can be operated by holding the control lever with your hand outstretched and swinging it from side to side.
As described in Japanese Patent Publication No. 136023, it has the advantage of being easier to operate compared to a control lever that swings in the front-rear direction, which is the direction toward or away from the operator. As shown in Publication No. 153432, the pivot axis of the operating lever was located off to one side of the driver's seat from the front of the center in the left-right direction of the aircraft. It has the disadvantage that it is difficult to operate unless it is operated with one hand, and there is a risk that it cannot be operated quickly when turning, etc., when it is necessary to switch between a low-speed operation state for work travel and a reverse operation state while operating the steering wheel.

対する足踏み操作とが交錯して、操作がやりずら
い欠点もある。 Furthermore, when switching between the low-speed operation state for work traveling and the reverse operation state, the clutch pedal is operated by the foot, so the operating position of the operating lever that provides the low-speed operation state for work travel or the reverse operation state is If the clutch pedal is set at the mounting position of the clutch pedal, the operation of the control lever and the operation of stepping on the clutch pedal are mixed, making it difficult to perform the operation.
そして、作業走行用低速操作状態の得られる操

えられる等、危険であつた。 If the operation position of the control lever that enables the low-speed operation state for work traveling is located near either the left or right foot, the machine may tilt and the foot may unexpectedly hit the lever, causing the machine to enter the high-speed state unexpectedly. It was dangerous because it could be switched.
本考案は、上記実状に鑑みて為されたものであ
つて、操作レバーの取付位置、並びに変速機構と
の連動構成を工夫することによつて、安全かつ迅
速に操作できるようにすることを目的とする。 The present invention was developed in view of the above-mentioned circumstances, and aims to enable safe and quick operation by devising the mounting position of the control lever and the interlocking structure with the transmission mechanism. shall be.
上記目的を達成する為の本考案の特徴構成は、
冒記した変速操作装置において、前記揺動レバー

から次の作用効果を奏する。 The characteristic structure of this invention to achieve the above purpose is as follows:
In the above-mentioned speed change operating device, the swing axis of the swing lever is located in front of the center of the driver's seat in the left-right direction of the aircraft body, and when the operating lever and the speed change mechanism are viewed from the front, the operating lever is By positioning the driver's seat at an operation position approximately in the center in the horizontal direction of the aircraft, a low-speed operation state for work travel can be obtained, and by swinging the driver's seat to an operation position on either side of the center position, high-speed operation for non-work travel can be achieved. This configuration provides the following effects.
即ち、操作レバーの揺動軸芯を運転座席の機体
左右方向中央の前方に位置させてあるので、左右
いずれの手によつても操作レバーが握り易く、回
行操作時等においても、その時のハンドルの操作
状況に応じて、何れか一方の手で操作レバーをし
つかり握り、迅速に操作できる効果がある。 In other words, the pivot axis of the control lever is located in front of the center of the driver's seat in the left-right direction of the aircraft, making it easy to grip the control lever with either the left or right hand. Depending on the operating situation of the handle, the operator can firmly grasp the operating lever with either hand and operate the lever quickly.
そして、作業走行用低速操作状態と後進操作状
態とに切換える際に、操作レバーの操作とクラツ
チペダルに対する足踏み操作とが交錯しない位
置、つまり、非作業走行用高速操作状態が得られ

付けることができるので、作業走行状態からの回
行操作が一層円滑に行えるように構成できる利点
がある。 Then, when switching between the low-speed operation state for work traveling and the reverse operation state, the operation lever is operated at a position where the operation of the operation lever and the foot operation on the clutch pedal do not overlap, that is, the high-speed operation state for non-work travel is obtained. Since the clutch pedal can be attached to the position side, there is an advantage that the structure can be configured so that turning operations from the working traveling state can be performed more smoothly.
その上、作業走行時において、左右両足のいず

体の揺れ等に起因して足が中央側に多少寄つたと
しても、レバーに衝突しにくく、作業走行を安全
かつ良好に行えるようになつた。 Furthermore, since the operating lever is positioned away from both the left and right feet during work travel, even if your foot moves a little toward the center due to the shaking of the machine, it will be less likely to collide with the lever. Now I can do it safely and well.
