し得るべく構成した移動農機の車速制御装置に関する。[Detailed description of the invention] This invention consists of an artificial control system that changes and adjusts the traveling speed of the machine to an arbitrary speed by manual operation, and an on-board threshing device that reduces the vehicle speed when the threshing load increases and increases the vehicle speed when the threshing load decreases. The human control system and the automatic control system are interlocked and connected via a friction transmission device, and the slip of the friction transmission device automatically controls the manual operation of the human control system. The present invention relates to a vehicle speed control device for a mobile agricultural machine configured to be operated with priority over automatic control of a control system.

車速を所望速度に変更する人為制御系と、脱穀負荷の増
大で車速を減少し、脱穀負荷の減少で車速を増大させる
自動制御系とが、摩擦伝動装置を介して連動連結されて
いるから、圃場内においては、操縦者が操作レバーから
手を離しておくと、車速は、脱穀負荷に応じて自動的に
増減されて便利であるが、脱穀負荷がほとんど零となる
圃場内枕地での方向転換時、もしくは、路上走行時には
、車速は、自動的に高速となるのである。In the vehicle speed control device of such mobile agricultural machinery, for example, in the vehicle speed control of a combine harvester, the operator operates a manually operated lever.
The human control system that changes the vehicle speed to a desired speed and the automatic control system that decreases the vehicle speed when the threshing load increases and increases the vehicle speed when the threshing load decreases are linked together via a friction transmission device. In the field, it is convenient for the vehicle speed to automatically increase or decrease depending on the threshing load if the operator takes his hand off the control lever, but this is useful in the headlands of the field where the threshing load is almost zero. When changing direction or driving on the road, the vehicle speed automatically increases.
そして機体方向転換後に次の刈取走行のために機体を操
縦して条合せを行う場合や、路上で操向させる場合には
、操縦者は、操作レバーを低速側に位置させるべく操作
レバーを握りながら、操向クラッチレバ−を操作させな
ければならず、操縦を誤まりやすい問題があった。After changing the direction of the machine, when operating the machine to adjust the conditions for the next reaping run, or when steering the machine on the road, the operator must hold the control lever to position it on the low speed side. However, there was a problem in that the steering clutch lever had to be operated, making it easy to make mistakes in steering.
本考案は、このような問題を解消することを目的とする
。The present invention aims to solve such problems.
即ち、本考案の移動農機の車速制御装置は、人為制御系

ッチを設けであることを特徴とする。That is, the vehicle speed control device for a mobile agricultural machine according to the present invention is characterized in that the grip of the operating lever of the manual control system is provided with a switch that cuts off the drive of the automatic control system.
つまり、人為制御系の操作レバーの握り部に自動制御系
の駆動を断つスイッチを設けであるから、機体を操向さ
せるときには、前記スイッチを自動制御を断つ側に切換
保持させておくと、車速は、脱穀負荷によって、制御さ
れることがない。In other words, since a switch that cuts off the drive of the automatic control system is installed in the grip of the operating lever of the human control system, when steering the aircraft, if the switch is kept switched to the side that cuts off automatic control, the vehicle speed is not controlled by the threshing load.
しかも、自動制御系の駆動を断つスイッチを、操作レバ
ーの握り部に設けであるから、例えば、操作レバーの回
動軌跡のある特定の箇所に前記スイッチを設けておいて
、レバーとの接当によって自動制御系の駆動を断つ場合
に比して、レバーの回動に伴わず、任意に自動制御系の
駆動を断つことができて便利である。Moreover, since the switch that cuts off the drive of the automatic control system is provided in the grip of the operating lever, for example, the switch may be provided at a specific location on the rotational trajectory of the operating lever, and the Compared to the case where the drive of the automatic control system is cut off by , it is convenient because the drive of the automatic control system can be cut off at will without the rotation of the lever.
