本考案は、トラクタ、田植機、コンバイン等の移動農機の作業機昇降制御装置 に関するものである。 The present invention relates to a working machine lifting control device for a mobile agricultural machine such as a tractor, a rice transplanter, or a combine harvester.

従来、農用トラクタの作業機昇降制御装置として特開平３─２５１１０２号公 報、特開平３─２５３４７９号公報及び実開平４─４２４２５号公報、実開平４ ─４３９１３号公報等が提案されている。 Conventionally, Japanese Patent Laid-Open Publication Nos. 3-251102, 3-253479, 4-42425, and 4-43913, etc. have been proposed as control devices for raising and lowering working machines for agricultural tractors.

上記に示す従来の作業機昇降制御装置は、対地作業機が耕深自動制御中（耕深 自動スイッチがＯＮで、かつ昇降操作レバーが最下げ位置の作業自動位置にセッ トされている状態）に、この自動制御に優先して対地作業機の昇降ができる昇降 操作スイッチが設けてある。 しかしながら、該昇降操作スイッチは運転席の一方側（右側）にのみ配設され ているために、通常枕地等の機体旋回操作は右旋回と左旋回とが交互に現出する 工程が多いにも係わらず、常に右手が昇降操作スイッチの操作に取られるために 、操向操作具（ステアリングハンドル）の右旋回操作及び左旋回操作は常に左手 を優先して操作する必要があり、左手の疲れが早い傾向があった。 また、走行機体の走行部がクローラ方式のものでは、操向操作具が左右のサイ ドクラッチの入り切り操作若しくは左右の油圧走行モーターの駆動停止操作をす る左右一対の操向操作レバーで構成されている例が多く、水田の代掻作業等の軟 弱田では走行機体が蛇行しやすいために直進性を維持するために常に操向操作レ バーを操作している。この場合には右手で常に昇降操作スイッチの操作をする関 係上、どうしても左手のみで左右一対の操向操作レバーを同時に把持して押し引 き操作することとなり、左手の疲労が著しくなる問題があった。 In the conventional work machine lifting control device shown above, the ground working machine is automatically controlling the working depth (when the automatic working depth switch is ON and the lifting control lever is set to the lowest working position). In addition, a lifting operation switch is provided that allows the ground work machine to move up and down in preference to this automatic control. However, since the raising / lowering operation switch is provided only on one side (right side) of the driver's seat, there are many processes in which the right and left turns alternate in the turning operation of the aircraft such as headland. Despite this, since the right hand is always operated by the raising / lowering operation switch, the left hand must always be prioritized for the right turning operation and the left turning operation of the steering operation tool (steering handle). I tended to get tired quickly. In addition, if the traveling part of the traveling machine is of a crawler type, the steering operation tool is composed of a pair of left and right steering operation levers for turning on and off the left and right side clutches or stopping the driving of the left and right hydraulic travel motors. In many soft fields such as paddling work in paddy fields, the steering aircraft is constantly operated to maintain straightness because the traveling aircraft easily meanders. In this case, because the right hand always operates the elevating and lowering switch, the left hand must hold the pair of left and right steering operation levers at the same time to push and pull, which causes significant left hand fatigue. there were.

上記問題点を解決するために本考案は、走行機体に作業機を上下昇降並びに左 右傾斜制御自在に連設し、該走行機体の運転席前方に操向操作具を設けたものに おいて、該運転席の一方側に前記作業機を上下昇降操作する昇降操作レバーと該 昇降操作レバーが作業自動位置にセットされている状態で、この自動制御に優先 して作業機の昇降ができる第一の昇降操作スイッチ及び作業機の傾斜姿勢を設定 制御する傾斜設定操作具等を備えた作業機制御ユニットを設け、運転席の他方側 に、前記作業機制御ユニットに備えた第一の昇降操作スイッチと同一機能を有す る第二の昇降操作スイッチを設け、該第二の昇降操作スイッチを第一の昇降操作 スイッチと並列にマイコン制御回路に組み込んだものである。 In order to solve the above-mentioned problems, the present invention provides a running machine in which a working machine is vertically connected and vertically tilted and tilted left and right, and a steering operation tool is provided in front of a driver's seat of the running machine. In a state in which the raising / lowering operation lever for vertically moving the working machine up and down on one side of the driver's seat and the raising / lowering operation lever are set to the automatic work position, the working machine can be raised / lowered prior to this automatic control. A working machine control unit equipped with one lifting operation switch and a tilt setting operation tool for setting and controlling the tilting posture of the working machine is provided, and the first lifting operation equipped with the working machine control unit is provided on the other side of the driver's seat. A second elevating operation switch having the same function as the switch is provided, and the second elevating operation switch is incorporated in the microcomputer control circuit in parallel with the first elevating operation switch.

Therefore, in the present invention, with the raising / lowering operation lever set to the work automatic position, the first raising / lowering operation switch and the second raising / lowering operation switch that can raise / lower the work machine are given priority over this automatic control. Since it is arranged on the left and right sides of the seat in a distributed state, when turning the traveling aircraft to the right on a headland, etc., operate the steering operation tool with priority on the right hand and operate the second lifting operation switch with the left hand to drive. It is possible to lift and lower the work machine as well as turn the machine to the right. On the contrary, when turning the aircraft to the left, operate the steering operation tool with priority to the left hand and operate the first raising / lowering operation switch with the right hand. You can Therefore, the right hand and the left hand are used alternately each time the left and right alternate turning operations are performed, and it is possible to eliminate the harmful effect of overusing one hand. Further, since the first and second elevating operation switches are arranged on both left and right sides of the driver's seat in a distributed state, they can be operated quickly and lightly.

I'm operating. In this case, the left and right hands can be used to operate the first and second raising / lowering operation switches 15 and 27, so that the pair of left and right steering operation levers 8 and 8 can be operated simultaneously with the hand that is easier to use. It can be held and pushed / pulled, reducing fatigue and improving workability. Further, since the first and second elevating operation switches 15 and 27 are arranged on the left and right sides of the driver's seat 7 in a distributed state, the operation feeling of the first and second elevating operation switches 15 and 27 on the left and right. It is possible to operate them almost the same and to operate them quickly and lightly.

【００１４】 （１）作業機をワンタッチで迅速に昇降操作できる昇降操作スイッチが左右どち らの手でも操作可能となり、操向のための操作レバー又は操縦ハンドルを旋回時 に旋回方向に合わせてどちらの手でも操作可能となり、作業負荷の軽減を図るこ とができる。 （２）特別の切替えスイッチを設けることなく、第一及び第二の昇降操作スイッ チを操作しても良いために操作性が向上する。 （３）第一及び第二の昇降操作スイッチ２７が運転席の左右両外側位置に振り分 け配置されるので、運転者が右手で第一の昇降操作スイッチを操作する場合の操 作感覚と左手で第二の昇降操作スイッチを操作する場合の操作感覚とが略々一致 して違和感なく迅速、軽快に操作できる。 （４）走行機体の直進操向操作の操縦操作が使い勝っての良い手を選択して対応 できるので疲労負担が軽減できる。 （５）第二の昇降操作スイッチを第一の昇降操作スイッチと並列にマイコン制御 回路に組み込んだことにより、第一の昇降操作スイッチを装備する作業機制御ユ ニットは従来同様のものを兼用利用することが可能となり、かつ操作機能の拡大 化を図ることができて安価にして操作性を向上させることができる。(1) The raising and lowering operation switch that allows the work implement to be quickly raised and lowered with one touch can be operated with either left or right hand, and the operation lever for steering or the steering handle can be adjusted to the turning direction when turning. Both hands can be used to reduce the workload. (2) The operability is improved because the first and second lifting operation switches may be operated without providing a special changeover switch. (3) Since the first and second elevating operation switches 27 are arranged so as to be distributed to both left and right outer positions of the driver's seat, a feeling of operation when the driver operates the first elevating operation switch with the right hand is provided. The operation feeling when operating the second elevating operation switch with the left hand is almost the same, and it can be operated quickly and lightly without any discomfort. (4) Since it is possible to select and respond to a hand that is convenient for the steering operation of the straight-ahead steering operation of the traveling aircraft, fatigue load can be reduced. (5) By incorporating the second elevating operation switch in parallel with the first elevating operation switch in the microcomputer control circuit, the work machine control unit equipped with the first elevating operation switch can also be the same as before. It is also possible to increase the operating function, and the cost can be reduced to improve the operability.
