本考案は、作業機が搭載された主フレームを、履帯が張設された左右のトラッ クフレームからなる走行装置に、主フレームの重心を走行装置に対して左右に移 動させる重心左右移動調節装置を介して連繋し、左右の走行伝動系にそれぞれ操 向手段を介装した農用作業車において、前記操向手段と重心左右移動調節装置と を、いずれか一方の操向手段を作動させると重心左右移動調節装置が主フレーム の重心を他方のトラックフレーム側へ若干移動させるべく作動するように連動連 繋することにより、機体回行を行うべく一方の操向手段を切るか制動すると機体 中心が駆動されている他側のトラックフレーム側へ若干移動するようにして前述 の課題を解決した。 The present invention provides a main frame mounted with a working machine to a traveling device composed of left and right track frames on which crawler belts are stretched, and the center of gravity of the main frame is moved left and right with respect to the traveling device. In an agricultural work vehicle that is connected through a device and has steering means for the left and right traveling transmission systems, respectively, when either one of the steering means and the center-of-gravity lateral movement adjustment device is operated, By moving the center of gravity of the main frame so that the center of gravity of the main frame moves slightly to the side of the other track frame, the center of the aircraft will move when one of the steering means is turned off or braked in order to rotate the aircraft. The above problem was solved by slightly moving to the side of the track frame on the other side where is driven.

走行装置はサイドクラッチ又はサイドブレーキ等の操向手段がそれぞれ介装さ れた左右の走行伝動系を介して駆動され、機体を回行させるべく一方の操向手段 を作動させ、他方の走行装置のみ駆動すると機体は回行する。その際、一方の操 向手段が作動させるとそれに連動して重心移動調節装置が作動して作業機が搭載 された主フレームの重心が駆動されている走行装置側へ若干移動するので、駆動 側の走行装置に対する負荷が増大して駆動力が大になり、操向手段が操向操作さ れたている側の走行装置に対する負荷が軽減されて滑り易くなり、それによりス ムーズに回行するようになってピッチングが無くなった。 The traveling device is driven via the left and right traveling transmission systems in which steering devices such as side clutches and side brakes are respectively interposed, and one steering device is operated to rotate the machine body, and the other traveling device. The aircraft will rotate if driven only. At that time, when one of the steering means is operated, the center-of-gravity movement adjusting device operates in conjunction with it, and the center of gravity of the main frame on which the working machine is mounted moves a little to the driving device side, so the driving side The load on the traveling device is increased and the driving force is increased, and the load on the traveling device on the side where the steering means is steered is reduced and the vehicle becomes slippery, which results in smooth running. Then pitching disappeared.

Direction support shafts 11, 11 are supported, and the bent portions of the L-shaped links 12, 12 are rotatably attached to both ends of the support shafts 11, 11, and the lower portion is attached to the bracket hanging from the main frame 1. One end of a horizontal control single-acting hydraulic cylinder 14, one end of which is connected to the main frame 1, is connected to the upper part of the swinging arm 13 which pivotally supports the above-mentioned front and rear links 12, At the top of twelve The lower end is connected to the front and rear of the track frame 6 by a shaft 6a, and is mounted on the main frame 1 for an inclination sensor and a grain culvert transport path. The detection values of the handling depth adjustment sensor, the traveling speed sensor, etc. are input to the microcomputer and each part is automatically controlled, and the hydraulic cylinder 14 expands and contracts according to the detection result of the tilt sensor, whereby the truck Since the frame 6 moves up and down via the swing arm 13, the rods 15 and 15, and the links 12 and 12, the main frame 1 is always held substantially horizontal.
【０００８】 次に、重心左右移動調節装置について説明すると、前記操向手段は、サイドク ラッチレバー、又は前後傾動することにより前処理装置を昇降させる操作をも兼 ねていて左右傾動するとサイドクラッチを断続するモノレバー等の操作により断 続作動し、該モノレバー又はサイドクラッチレバーに対設したサイドクラッチス イッチの開閉作動も前記マイコンに入力される。その際、いずれか一方のサイド クラッチを切り操作すると、図３に示すごとくマイコンの他側の制御系のタイマ ーがセットされ、一定時間だけの出力によりその側の油圧シリンダ１４の油路に 介装された電磁弁が中立位置から下げ側に作動し、設定時間経過後に中立位置に 復帰するので、サイドクラッチが切れていない他側の油圧シリンダ１４が縮小し て主フレームが下降するので、機体重心が駆動されている走行装置側に移動する こととなり、それにより駆動側の走行装置に対する負荷が大になって駆動力が増 大し、サイドクラッチが切れた側の走行装置に対する負荷が軽減されて滑り易く なり、機体はピッチングすることなくスムーズに回行する。回行方向を逆方向に した場合も同趣旨の重心移動制御が行われる。Next, the center-of-gravity lateral movement adjusting device will be described. The steering means doubles as a side clutch lever or an operation of raising and lowering the pretreatment device by tilting back and forth. Intermittent operation is performed by operating an intermittent monolever or the like, and the opening / closing operation of a side clutch switch opposite the monolever or the side clutch lever is also input to the microcomputer. At that time, when either one of the side clutches is disengaged, the timer of the control system on the other side of the microcomputer is set as shown in FIG. 3, and the output from the hydraulic cylinder 14 on that side is output by the output for a certain period of time. The mounted solenoid valve operates from the neutral position to the lower side and returns to the neutral position after the set time elapses, so that the hydraulic cylinder 14 on the other side where the side clutch is not disengaged contracts and the main frame descends. The center of gravity moves to the driving device that is driven, which increases the load on the driving device on the driving side and increases the driving force, and reduces the load on the driving device on the side clutch disengaged side. It becomes slippery and the aircraft turns smoothly without pitching. Even when the traveling direction is reversed, the center-of-gravity movement control with the same effect is performed.

A paddy sensor (1), a paddy sensor (2), and a paddy sensor (3), which detect the amount of paddy in three steps as an output device, are attached in order from the bottom, and the detected values are input to a microcomputer, and a side clutch switch is provided. Is ON (side clutch on that side is disengaged), for example, when turning left by disengaging the left side clutch, the paddy sensor (3) is ON because the paddy filling amount is large. , The right side hydraulic cylinder 14 is reduced to the setting 3 and tilts to the right side, whereby the center of gravity of the machine moves to the right side by the amount corresponding to the set value, the driving force on that side increases, and the left side traveling device The load on the skid is reduced As a result, the airframe can be smoothly moved as in the above-described embodiment. When the paddy sensor (3) is OFF and the paddy sensor (2) is ON, the hydraulic cylinder 14 on the right side is reduced to the set value 2, and the paddy sensor (2) is OFF and the paddy sensor (1 ) Is ON, and the paddy sensor (1) is also OFF, the hydraulic cylinder 14 is reduced by an amount corresponding to setting 2, setting 1 or setting 0. Further, when the right side clutch is disengaged, as shown in FIG. 5, the movement control of the center of gravity of the airframe similar to that at the time of leftward traveling is performed.

Even if the left and right movements are adjusted by the set amount based on the above, the movement adjustment of the center of gravity at the time of traveling of the airframe can be performed similarly to the above-described embodiment.
