まず、図1及び図2を参照しながら、コンバインの全体構造について説明する。コンバインは、走行部としての左右一対の走行クローラ2にて支持された走行機体1を備えている。走行機体1の前部には、穀稈を刈り取りながら取り込む6条刈り用の刈取装置3が、単動式の昇降用油圧シリンダ4にて刈取回動支点軸4a回りに昇降調節可能に装着されている。走行機体1には、フィードチェン6を有する脱穀装置5と、脱穀装置5から取り出された穀粒を貯留する穀粒タンク7とが横並び状に搭載されている。脱穀装置5が走行機体1の進行方向左側に、穀粒タンク7が走行機体1の進行方向右側に配置されている。走行機体1の後部に旋回可能な排出オーガ8が設けられている。穀粒タンク7の内部の穀粒が、排出オーガ8の籾投げ口9からトラックの荷台またはコンテナ等に排出されるように構成されている。刈取装置3の右側方で、穀粒タンク7の前側方には、運転キャビン10が設けられている。
次に、図1~図4を参照しながら、脱穀装置5の構造を説明する。図1~図4に示されるように、脱穀装置5には、穀稈脱穀用の扱胴226と、扱胴226の下方に落下する脱粒物を選別する揺動選別盤227及び唐箕ファン228と、扱胴226の後部から取り出される脱穀排出物を再処理する処理胴229と、揺動選別盤227の後部の排塵を排出する排塵ファン230とが備えられている。なお、扱胴226の回転軸芯線は、フィードチェン6による穀稈の搬送方向(換言すると走行機体1の進行方向)に沿って延びている。刈取装置3から穀稈搬送装置224にて搬送された穀稈の株元側は、フィードチェン6に受け継がれて挟持搬送される。そして、この穀稈の穂先側が脱穀装置5の扱室内に搬入されて扱胴226にて脱穀されることになる。
次に、図3及び図4を参照しながら、唐箕ファン228からチャフシーブ239に供給する選別風の風路構造について説明する。
次に、図5を参照しながら、刈取装置3、脱穀装置5及びフィードチェン6等の駆動構造について説明する。図5に示されるように、エンジン14の前側及び後側にその出力軸70を突出する。エンジン14の前側の出力軸70に自在継手83を介してミッションケース71の走行入力軸84を連結されている。エンジン14の回転駆動力が、前側の出力軸70からミッションケース71に伝達されて変速されたのち、左右の車軸72を介して左右の走行クローラ2に伝達されるように構成されている。従って、左右の走行クローラ2はエンジン14の回転駆動力にて駆動されることになる。

次に、図20及び図21を参照しながら、チャフシーブ239の強制開放制御の第3実施形態について説明する。第3実施形態では、ファンシャッタ270のシャッタレバー271に、第2実施形態と同じ構成のシャッタ用連係手段290′を介して強制閉止電動モータ291′を関連させている点において、第2実施形態と相違している。その他の構成は、基本的に第2実施形態と同様である。
次に、図22及び図23を参照しながら、チャフシーブ239の強制開放制御の第4実施形態について説明する。第4実施形態では、前部チャフシーブ261に対する連係手段290及び強制開放電動モータ291をなくして、(前部)開閉機構264を、各ワイヤ265,273と機械的に連動連結させるだけの構成にする一方、後部チャフシーブ262のチャフ変更杆262bを、第2実施形態と同じ構成の後部開閉機構264″の作用にて前後移動するように構成し、後部開閉機構264″のチャフレバー285″に、第2実施形態と同じ構成の後部用連係手段290″を介して後部用強制開放電動モータ291″を関連させている点において、第2実施形態と相違している。その他の構成は、基本的に第2実施形態と同様である。
次に、図24~図26を参照しながら、チャフシーブ239の強制開放制御の第5実施形態について説明する。第5実施形態では、強制開放電動モータ391を、排藁チェン234の下方においてチャフ用検出アーム381等と横並びに配置した点において、第1実施形態と相違している。その他の構成は基本的に第1実施形態と同様である。図24~図26に示すように、排藁チェン234の下方に位置する4番樋フレーム251に、略箱型のモータボックス252が取り付けられている。モータボックス252内に、アクチュエータとしての強制開放電動モータ391が収容されている。また、モータボックス252内には、回動部材としてのセクタギヤ394が、前後に延びる回動軸395にて回動可能に枢支されている。セクタギヤ394は、強制開放電動モータ391による出力ギヤ393の正逆回転駆動にて、図24及び図25に示す待機位置から、図26に示す強制開放位置までの範囲において、回動軸395回りに回動するように構成されている。
