【発明の属する技術分野】
本発明は機体左右両側に走行クローラを支持高さ調節自在に支持して機体を水平に維持するコンバインに関する。
【０００２】
【発明が解決しようとする課題】
従来、左右走行クローラを装設させる左右トラックフレームを機台に前後スイングアームを介して昇降自在に取付けると共に、水平シリンダによって前後スイングアームを揺動させて走行クローラ接地部を昇降させる技術がある。しかし乍ら、機台下側に固定させる本機フレーム、または本機フレームにトラックフレームを連結させるスイングアームなどを走行クローラの内周面側に配置させ、左右走行クローラに対してスイングアームなどの水平制御構造を左右独立して設けることにより、左右走行クローラを支持させる左右本機フレームと機台の連結に、左右に長尺な剛性材を特別に設ける必要があり、左右本機フレーム取付け構造の簡略化を容易に行い得ないと共に、本機フレームまたはスイングアームなどによって走行クローラ内周面側の空間が少なくなり、走行クローラ内周面に入り込んだ泥土が外部に排出される開放空間を充分に形成し得ず、走行クローラ内周面側に多くの泥土が付着し易い不具合がある。また、スイングアームに水平シリンダを連結させることにより、スイングアームが上下方向に長尺に形成される不具合があると共に、前後スイングアームの形状を異ならせて製造する必要がある。また、走行路面の凸部に走行クローラ接地面を追従させるイコライザローラを設けることにより、走行クローラの横滑り変形によってイコライザローラが走行クローラに不適正に圧接し易い不具合があり、走行クローラ支持構造の簡略化並びに支持剛性の向上などを容易に図り得ない等の問題がある。
【０００３】
【課題を解決するための手段】
そこで、本発明では、脱穀部及び刈取部などを機台に装設させ、前後方向に延設させる左右本機フレームを機台下側に固定させ、左右二組の前後スイングアームを介して左右本機フレームの機外側に左右トラックフレームを設け、左右トラックフレームに取付けたトラックローラ及びイコライザローラ及びテンションローラと駆動スプロケットとを介して左右走行クローラを装設させ、左右水平シリンダによって左右二組の前後スイングアームを左右各別に揺動させ、左右走行クローラの接地面高さを変更させるコンバインにおいて、左右方向に延設させる前後支点軸を左右本機フレームに連結させ、左右二組の前後スイングアームを前後支点軸に取付けたコンバインであって、トラックフレームにイコライザフレームを揺動自在に取付け、同イコライザフレームに前後イコライザローラを一組として取付けると共に、イコライザローラ間にクローラ外れ防止体を設け、同クローラ外れ防止体によって走行クローラにイコライザローラを圧接支持させる一方、トラックフレームにトラックローラを、上記イコライザローラの前方に位置させて設けると共に、同トラックローラ間にクローラ外れ防止体を設け、同クローラ外れ防止体の後端に突起を一体形成して、同突起をイコライザローラ間のクローラ外れ防止体の前部上方に配置させ、イコライザローラの前方上昇を、クローラ外れ防止体の前端と上記クローラ外れ防止体の突起との当接により規制すると共に、トラックフレームに、イコライザローラの後方斜上方に配置させるストッパを固定させ、同ストッパにイコライザローラを当接させて後方上昇を規制するように構成したことを特徴とするコンバインを提供するものである。

However, this machine frame that is fixed to the lower side of the machine base, or a swing arm that connects the track frame to this machine frame is arranged on the inner peripheral surface side of the traveling crawler, and the swing arm etc. By providing the horizontal control structure independently on the left and right, it is necessary to provide a rigid material that is long on the left and right to connect the left and right machine frames that support the left and right traveling crawlers. Can not be easily simplified, and the space on the inner peripheral surface of the traveling crawler is reduced by the machine frame or swing arm, etc., and there is enough open space for mud mud entering the inner peripheral surface of the traveling crawler to be discharged to the outside. Cannot be formed, and a lot of mud is likely to adhere to the inner peripheral surface of the traveling crawler. Further, by connecting the horizontal cylinder to the swing arm, there is a problem that the swing arm is formed in a long vertical direction, and it is necessary to manufacture the front and rear swing arms with different shapes. In addition, by providing an equalizer roller that follows the traveling crawler grounding surface on the convex part of the traveling road surface, there is a problem that the equalizer roller tends to improperly press against the traveling crawler due to side slip deformation of the traveling crawler, and the traveling crawler support structure is simplified. There is a problem that it cannot be easily achieved and improvement of support rigidity.
