JP 2006-115740 A

しかしながら、上記構成の掻込ペダルは、生産コストの点でなお多くの問題が残っており、構成の簡易化が望まれていた。   However, many problems still remain with respect to the production pedal in terms of production cost, and simplification of the configuration has been desired.

本発明の目的は、構成の簡易化により、生産コストを改善することができるコンバインの操縦装置を提供することにある。   An object of the present invention is to provide a combine steering apparatus capable of improving production costs by simplifying the configuration.

請求項１に係る発明は、操縦席の前部に配置した左右の傾動操作が可能な操舵レバーと、この操舵レバーと一体構成でその操作力を昇圧スプール軸に受けるリリーフバルブとを備え、このリリーフバルブによって油圧制御されるサイドクラッチ機構を介して左右の走行動力を断接制御するコンバインの操縦装置において、上記操舵レバーの下方のフロアには、踏込み操作が可能な掻込ペダルを設け、この掻込ペダルの踏込力を伝えるケーブルを上記昇圧スプール軸と連結して上記サイドクラッチ機構により左右の走行動力を同時に断接制御可能に構成したことを特徴とする。   The invention according to claim 1 is provided with a steering lever arranged at the front part of the cockpit and capable of tilting right and left, and a relief valve that is integrated with the steering lever and receives the operating force on the booster spool shaft. In a combine control device that controls connection and disconnection of the left and right traveling power via a side clutch mechanism that is hydraulically controlled by a relief valve, a floor pedal is provided on the floor below the steering lever. A cable for transmitting the depression force of the take-in pedal is connected to the boost spool shaft so that the left and right traveling power can be simultaneously connected and disconnected by the side clutch mechanism.

請求項１の発明のコンバインの操縦装置は、操舵レバーの左右の傾動操作を受けると操舵レバーと一体のリリーフバルブによって制御されるサイドクラッチ機構により左右の走行動力を断接制御することによって旋回走行が可能となり、また、ケーブルを介して掻込ペダルの踏込み操作を受けるとサイドクラッチ機構を介してを左右の走行動力が同時に断接制御されて走行停止したまま刈取動作を可能とする。したがって、旋回走行用のリリーフバルブによって掻込み停車することができることから、部材削減によって生産コストを低減することが可能となる。   According to a first aspect of the present invention, the combine steering apparatus is turned by controlling the left and right traveling power by the side clutch mechanism controlled by the relief valve integrated with the steering lever when the steering lever is tilted to the left and right. In addition, when a depression pedal operation is received via a cable, the right and left traveling powers are simultaneously connected and disconnected via the side clutch mechanism, and the cutting operation can be performed while the traveling is stopped. Therefore, since the vehicle can be stopped by the relief valve for turning, the production cost can be reduced by reducing the number of members.
