以下、図面に基づいて、本発明の実施例を具体的に説明する。
コンバイン４は、図４および図５に示すように、クロ−ラ１１を装備した走行車体１上に、脱穀装置２を搭載し、その前側に刈取前処理装置３を連結して一連の刈取脱穀作業ができる構成としている。
まず、刈取前処理装置３は、図４および図５に示すように、基部を走行車体１の前部に設けた支持台（図示を省略している）に上下回動自由に枢着した刈取フレ−ム１２を前方下方へ延長し、この刈取フレ−ム１２に各装置を装着して構成している。すなわち、刈取前処理装置３は、前端下部に分草杆１３を、その背後に傾斜状にした穀稈引起し装置１４を、その後方低部には刈取装置１５を、更に、図２に示すように、刈取穀稈を搬送する株元搬送装置１６と、穂先搬送装置１７と、扱深さ調節装置１８と、穀稈供給装置５とを順次穀稈の受継搬送ができるように配置して前述の刈取フレ−ム１２に取り付けて伝動可能に構成している。
そして、扱深さ調節装置１８は、従来から公知で図２に示すように、調節チェン１８ａと挾持杆１８ｂとからなり、始端部を前記株元搬送装置１６の終端部に搬送穀稈の株元を受継可能に臨ませて設け、後方上方に延長して終端部を穀稈供給装置５の始端部に臨ませて設けている。そして、扱深さ調節装置１８は、図２に示すように、始端部を刈取フレ−ム１２に枢着して終端側が搬送穀稈の稈身方向に沿って上下に揺動する構成とし、図示を省略している扱深さ制御モ−タ−に制御可能に接続して構成している。
なお、穂先センサ１９は、図２に示すように、穀稈の搬送通路の上方に垂下して設け、搬送穀稈の穂先位置（穀稈の丈）を検出して図示しないコントロ−ラに入力する構成としている。そして、コントロ−ラは、上記扱深さ制御モ−タ−に制御信号を出力するように接続して扱深さ自動制御を行なう構成としている。
つぎに、穀稈供給装置５は、図２に示すように、刈取前処理装置３の終端部に供給チェンと挟持杆とからなり、前記扱深さ調節装置１８から受継いだ搬送穀稈を脱穀装置２側に送る構成としている。この構成において、穀稈供給装置５は、搬送穀稈の株元を挟持して搬送し、穀稈上部（穂部）を穂先搬送装置１７の穂先ラグが係止して持ち回るように奥側（図４の操縦座席２０の方向）へ搬送して穀稈を横倒し状にして脱穀装置２側へ引継がせる構成としている。
このように構成した刈取前処理装置３は、図５で解るように、油圧装置によって伸縮する刈取昇降シリンダ−２１によって支持し、下部の通常の作業位置と上部の非作業位置との間を昇降する構成とし、中間位置に刈取り高さ調節ができる構成としている。
つぎに、脱穀装置２は、図４および図５に示すように、フィ−ドチェン２２を有し、従来から公知の如く、上側に扱胴を軸架した扱室を配置し、下側に揺動選別装置や圧風唐箕を内装した選別室を設け、供給された刈取穀稈を脱穀選別する構成としている。そして、フィ−ドチェン２２は、上側に添わせて挟持杆２３が設けられ、穂先部を上記扱室に挿入した穀稈の株元を挟持して搬送する構成としている。
そして、入り口漏斗６は、図１、図３、図４に示すように、上記脱穀装置２の扱室の前側（穀稈供給側）に接続して設け、上面で引継ぎ穀稈を受継いで扱室に供給する機能を有するが、前記穀稈供給装置５の搬送終端部から段差を付けた低い位置（図１参照）に配置して構成している。そして、穀稈ガイドゴムプレ−ト（穀稈ガイド用のゴムプレート）１０は、図１乃至図３に示すように、刈取前処理装置３の後部機枠７に取付けた支持部材８に固着して上記した入り口漏斗６に垂れ下げて連続した状態に設けている。そして、支持部材８は、図２乃至図４に示すように、基部側を前述のとおり後部機枠７に固着し、先端側を後述する補助受継チェン９ａ側に若干下向きに傾斜させて設けている。
つぎに、前部受継チェン９ｂは、図３に示すように、前記フィ−ドチェン２２の搬送始端部のすぐ前側に、フィ−ドチェン２２の始端部を分割したように設け、刈取前処理装置３側の前述した穀稈供給装置５から受け継いだ穀稈を後続するフィ−ドチェン２２に受け継がせる構成としている。そして、上述の補助受継チェン９ａは、図３に示すように、前部受継チェン９ｂとフィ−ドチェン２２との内側に配置して設け、前記前部受継チェン９ｂの受継作用時に、穀稈の穂先側を支持できる構成としている。そして、前部受継チェン９ｂは、図３に示すように、その搬送始端部を、補助受継チェン９ａの搬送始端部より前側位置（穀稈搬送方向の上手側）に配置し、終端部分も上記補助受継チェン９ａの終端部分より前側に位置させて構成している。この場合、補助受継チェン９ａは、前部受継チェン９ｂの終端部とフィ−ドチェン２２の搬送始端部との間の穀稈受け継ぎ作用を補助すると共に、超短稈（前部受継チェン９ｂまで株元が届かない程度の短い穀稈）を受け継ぐことができる構成としている。
そして、前部受継チェン９ｂと補助受継チェン９ａは、請求項に記載した受継チェン９に相当し、図示は省略したが、刈取前処理装置３の後部から伝動装置を介して回転動力を伝動する構成としている。
そして、穀稈ガイド杆２４、２５（第１穀稈ガイド２４、第２穀稈ガイド２５）は、図２および図３に示すように、基部を前側の前記刈取前処理装置３の取付部材２６にそれぞれ取り付けて後方に延長して補助受継チェン９ａと前部受継チェン９ｂとの上側（穀稈搬送面）に沿わせて設け、更に、後方の前記フィ−ドチェン２２の挟持杆２３の側方位置まで延長して構成している。そして、穀稈ガイド杆２４、２５は、図３に示すように、二本の先端部が挟持杆２３を挟むように両側に位置し、穀稈の受け継ぎを確実に行なう構成としている。そして、穀稈ガイド杆２４、２５は、弾性素材を用いて構成しており、前部受継チェン９ｂと補助受継チェン９ａとの位置が上下に変化したときにも充分に順応することができ、更には、受継穀稈の層厚の変化にも適確に対応できるものとなっている。
つぎにその作用について説明する。
まず、エンジンを始動して、刈取クラッチや脱穀クラッチを入り操作して機体の回転各部を伝動しながら、走行車体１を前進走行してコンバイン４による刈取脱穀作業を開始する。すると、圃場の穀稈は、前端下部にある分草杆１３によって分草作用を受け、ついで穀稈引起し装置１４の引起し作用によって倒伏状態から直立状態に引き起こされ、株元が刈取装置１５に達して刈り取られ、株元搬送装置１６と穂先搬送装置１７に受け継がれて順次連続状態で後部上方に搬送される。
そして、穀稈は、扱深さ調節装置１８から穀稈供給装置５に順次連続状態で受け継がれ、その終端部分において、穂先側が穂先搬送装置１７によって持ち回られながら横倒し状態になって穀稈ガイドゴムプレ−ト１０上に達する。そして、穀稈は、株元が穀稈供給装置５の終端部から離れると、各穀稈ガイド２４、２５に案内されて前部受継チェン７の始端部に達して挟持され、穂先側が垂れ下がっている穀稈ガイドゴムプレ−ト１０上を滑るように案内されて入り口漏斗６上に落下するようにして整然と引き継がれることになる。このとき、引継ぎ穀稈は、穀稈供給装置５の終端部から段差のある状態に低い位置の入り口漏斗６上に滑り落ちるものであるから搬送抵抗がほとんどなく、従来のような穂先遅れの状態にはならずに扱室に供給されることになる。
このようにして、引継ぎ穀稈は、株元が前部受継チェン９ｂの終端部から補助受継チェン９ａの補助を受けながらフィ−ドチェン２２に受け継がれ、穂先側が、上述したように、入り口漏斗６から扱室に供給されて脱穀作用を受けながら後方に搬送されることになる。
以上述べたように、本発明は、刈取前処理装置３の穀稈供給装置５の終端部から脱穀装置２の入り口漏斗６上に引継がれる穀稈は、高い位置から段差のある低い位置にきわめて円滑に引継がれて脱穀装置２に供給されるものとなった。
そして、穀稈ガイドゴムプレ−ト１０は、刈取前処理装置３の穀稈供給装置５から脱穀装置２の入り口漏斗６上に引継がれる穀稈の搬送姿勢を安定させることができて、穂揃いを良くしながら脱穀装置２に供給できるから脱穀効率を高める効果を発揮することができる。
別実施例１
つぎに、図６および図７に基づいて別実施例１を説明する。
別実施例１は、扱胴３０の改良に関し、始端部における藁の巻き付きを防止して、扱室３１に供給された穀稈を素早く扱歯３２側に誘導・案内する（藁の取込みを良くする）構成としたものである。
まず、扱胴３０は、図６に示すように、始端部前面の全周に帯状幅の平坦面３３を形成し、この平坦面３３の全周に連続して傾斜案内面３４を形成した構成としている。
そして、誘導スクレパ−３５は、前記平坦面３３に正面視（図６参照）において、左右対称な位置に取り付けるが、扱胴３０の回転方向（矢印Ａ）に対して供給された藁を外周側に誘導できるように構成している。すなわち、誘導スクレパ−３５は、図６で解るように、回転方向（矢印Ａ）の先端部が内周側にあり、終端部が外周側位置するように誘導傾斜面３５ａを設け、扱胴３０の回転によって藁を外周側に誘導する構成としている。
そして、スパイラル羽根３６は、図６および図７に示すように、スパイラル形状に捻転し、上記平坦面３３の外周縁に連続する傾斜案内面３４を四等分した位置にそれぞれ装着している。実施例の場合、全周に四枚を設けているが、枚数にはこだわらない。
そして、扱胴３０は、周面に複数の扱歯３２を取り付けて、扱室３１内に軸架している。図７において、３７は穀稈供給口、３８は選別網、３９は排塵口、４０は排藁口である。
以上のように構成された別実施例１は、扱胴３０が矢印Ａの方向に回転されている扱室３１に穀稈供給口３７から穀稈を供給して脱穀作業を開始すると、誘導スクレパ−３５は、扱胴３０と共に回転して藁を外側へ誘導する。この場合、誘導スクレパ−３５は、供給された藁を先端部が内側に、終端部が外側に位置する誘導傾斜面３５ａによって回転に伴い外周のスパイラル羽根３６側に誘導する。
このようにして、穀稈は、誘導スクレパ−３５からスパイラル羽根３６に達すると、捻転形状のスパイラル面によって傾斜案内面３４上を案内されて、扱胴３０外周の扱歯３２に供給される。
以上述べたように、別実施例１は、穀稈を誘導スクレパ−３５とスパイラル羽根３６との共同作用により扱歯３２の位置に誘導案内して回転部分に巻き付くことなく、扱胴３０の始端部分における穀稈の取込み性能を一段と向上する特徴がある。
別実施例２
つぎに、図８乃至図１０に基づいて別実施例２を説明する。
別実施例２は、脱穀装置の排藁部に設けた排藁チェンのオ−プン装置に関し、排藁チェンと挟持杆との間に排藁が詰ったとき容易に清掃、取り除きができる装置である。
まず、排藁チェン４５は、基部側を駆動スプロケット４６に係合し、先端側を従動スプロケット４７に係合して脱穀装置の排藁部に設けている。そして、駆動スプロケット４６は、図示しない扱胴回転軸の終端部から回転動力が伝動される入力プ−リ４８に伝動機構４９を介して伝動可能に構成している。そして、伝動機構４９は、駆動スプロケット４６と入力プ−リ４８と共に伝動ケ−ス５０に軸受支持した構成としている。そして、他方側の従動スプロケット４７は、テンション作用ができるように軸受して構成している。そして、排藁チェン４５は、回動支点軸５１に回動自由に支持した支持ア−ム５２を先端側に連結して固着しており、基部側の前記伝動ケ−ス５０の固定状態を解除すれば、上方にオ−プン回動できる構成としている。
すなわち、前記伝動ケ−ス５０は、図８および図１０に示すように、脱穀装置に固定して排藁チェン４５の上方に配置している上部フレ−ム５３に、取付板５４と、連結部材５５と、固定ボルト５６とを介して係脱自由に連結支持した構成としている。具体的には、図１０に示すように、上部フレ−ム５３の取付板５４に、伝動ケ−ス５０側の連結部材５５を重ねて固定ボルト５６によって固着する構成としている。
このように、固定ボルト５６は、取付板５４に連結部材５５を重ね合わせて、その上側からねじ部を差し込んで、ハンドル５７によって回してねじ止めする構成としている。
つぎに、排藁チェン４５は、オ−プンするときには、ハンドル５７によって取り付け時の逆に回して固定ボルト５６を外し、取付板５４から連結部材５５を分離して上方に回動することができる。
そして、排藁チェン４５は、下側に沿わせて挟持杆５８を設け、排藁を挟持しは搬送する構成とし、穂先側には、穂先排藁ラグ５９を併設して構成している。
別実施例２は、上述のように、排藁チェン４５を単独でオ−プン可能に構成しているから、挟持杆５８との間に藁詰りが発生すると、固定ボルト５６を外して比較的簡単に上方に回動して詰っている藁の取り除きができる利点がある。
別実施例３
つぎに、図１１乃至図１４に基づいて別実施例３を説明する。
別実施例３は、揺動選別棚６０の終端部の外側に設けた排塵ガイド６１に関し、排塵物の排出作用を促進しながら圃場の既刈稈側に誘導落下するものである。
まず、コンバインに搭載された脱穀装置６２であって、揺動選別棚６０は、図１１に示すように、脱穀装置６２の選別室６３に揺動自由に支架して設けている。そして、揺動選別棚６０は、後部にストロ−ラック６４を配置して設け、終端部にはゴム垂れ６５を垂下して設け、選別しながら移送してきた排塵物を終端部から機外に排塵する構成としている。そして、排塵ガイド６１は、図１２および図１３に示すように、左右二つを揺動選別棚６０に取り付け、背面視（図１２参照）において、右側を下方にして傾斜し排塵物を圃場の既刈稈側に誘導落下する構成としている。そして、排塵ガイド６１は、後縁の下側に切欠部６１ａを設けて排藁カッタ−６６の拡散ロ−タ６７に接近した配置構成としている。
そして、排塵装置６８は、実施例の場合、排塵風を排塵ガイド６１と拡散ロ−タ６７側に排塵する構成にしている。
別実施例３は、以上のように構成しているから、コンバインによる刈取脱穀作用に伴って揺動選別棚６０の終端にあるストロ−ラック６４から外側に排塵された排塵物は、排塵ガイド６１上に落下する。すると、排塵物は、排塵ガイド６１の傾斜によって既刈稈側に案内されて落下しながら拡散ロ−タ６６に達し、圃場面に拡散される。このようにして、排塵物は、圃場の既刈稈側に落下するから次工程においてコンバインの前端部にある分草杆に引っ掛かることがない。
そして、実施例の場合、拡散ロ−タ６７は、上側の排藁カッタ−６６で切断した藁と、排塵装置６８から排塵された排塵物と、排塵ガイド６１上からの排塵物とを受け継いで圃場面に拡散する。
このように、別実施例３は、揺動選別棚６０の棚先から排出される排塵物を圃場の既刈稈側に迅速に排塵して詰りや停滞を起こさせない特徴を有する。 Embodiments of the present invention will be specifically described below with reference to the drawings.
