本発明は、刈刃８および刈刃８により刈取った穀稈を搬送する搬送装置１１を有し上下回動自在に設けた刈取部４と、該刈取部４の後方に設けた脱穀装置３に穀稈の穂先側を供給する穀稈供給装置２２と、前記刈取部４と前記穀稈供給装置２２との間に設けられ、穀稈引継搬送チエン４０および挾扼杆４１とからなりその始端部を前記搬送装置１１の終端に対して遠近変更自在に構成した引継搬送装置２４とを設けたコンバインにおいて、前記穀稈供給装置２２の始端部の前記引継搬送装置２４側の側部には、前記穀稈供給装置２２と平行であって補助引継チエン５３と引継ガイド５５とにより穀稈の株元側を挟持搬送する補助引継装置５０を設け、該補助引継チエン５３の始端側の駆動歯車５１は前記引継搬送装置２４が前記搬送装置１１の終端に対して上下回動するときの回動中心となる回転横軸３１に設け、前記補助引継チエン５３の終端側の受動歯車５２は前記脱穀装置３側に基部を回動自在に取付けた取付部材５４の先端に取付けたコンバインの補助引継装置としたものである。
本発明は、前記刈取部４は、前記刈刃８および前記株元側搬送装置１１を設けた刈取部フレーム１３に、基部を機体フレーム１に回動自在に設けた刈取支持部材１４の先端を固定し、該刈取支持部材１４の基部には刈取入力プーリー１９を一端に固定した回転伝達軸１８を軸装した横伝動回転筒１５を設け、該横伝動回転筒１５の他端側に設けた伝動ケース２７に、前記回転伝達軸１８の回転により回転する回転横軸３１を軸装した横取付回転筒２９の基部を回転自在に取付け、該横取付回転筒２９の中間部に前記株元引継搬送装置２４を設け、前記横取付回転筒２９より突出する回転横軸３１に前記駆動歯車５１を設けたコンバインの補助引継装置としたものである。
【０００６】
【実施例】
本発明の実施例を図により説明すると、１はコンバインの機体フレーム、２は走行装置、３は脱穀装置、４は機体の前方位置に設けた刈取部である。前記刈取部４の最前方位置には分草体５を設け、該分草体５の後方には分草した穀稈を引き起こす引起装置６を設け、該引起装置６の後方に掻込装置７を設け、該掻込装置７の下方に穀稈の株元側を切断する刈刃８を設けている。９はスターホイルである。
前記刈刃８の上方位置には、刈取った穀稈の株元を搬送する株元側搬送装置１１を設け、該株元側搬送装置１１の上方位置には穀稈の穂先を搬送する穂先側搬送装置１２を設ける。そして、前記分草体５や株元側搬送装置１１および穂先側搬送装置１２等は、刈取部フレーム１３に取付け、刈取部フレーム１３は前後方向の刈取支持部材１４の先端に固定し、刈取支持部材１４の基部には左右方向の横伝動回転筒１５を固定し、横伝動回転筒１５を前記機体フレーム１の前側に設けた受台１６に回転自在に取付け、もって、刈取部４は刈取上下シリンダ１７により横伝動回転筒１５中心に上下動する。図示は省略するが、前記刈取支持部材１４は中空筒により形成し、刈取支持部材１４には刈取部４に回転を伝達する回転伝達軸を軸装する。前記横伝動回転筒１５には回転伝達軸１８を軸装し、前記回転伝達軸１８の一端には刈取入力プーリー１９を固定する。２０はミッションケース、２１は出力プーリーである。
【０００７】
前記株元側搬送装置１１と前記穂先側搬送装置１２の終端部には、脱穀装置３の側部に設けた穀稈供給装置２２に穀稈を引継ぐ穂先引継搬送装置２３および株元引継搬送装置２４を設ける。前記横伝動回転筒１５の他端に伝動ケース２７の基部を固定し、伝動ケース２７内には伝達歯車２８群を設ける。伝動ケース２７の先端には、左右方向の横取付回転筒２９の基部を回転自在に取付け、横取付回転筒２９には上方に突出する縦取付部材３０の基部を固定し、縦取付部材３０の上下中間部に前記株元引継搬送装置２４を取付け、縦取付部材３０の上端に前記穂先引継搬送装置２３を取付ける。前記横取付回転筒２９内には前記伝動ケース２７の最終の伝達歯車２８を軸装する回転横軸３１を貫通させて軸装し、回転横軸３１より前記穂先引継搬送装置２３および株元引継搬送装置２４に回転を伝達する。
【０００８】
前記受台１６側には扱深さ調節用モーター３２を設け、扱深さ調節用モーター３２にはアーム３３の基部を取付け、アーム３３の先端にはロッド３４の下端を軸着し、ロッド３４の上端は基部を前記受台１６側に回動自在に取付けた回動アーム３６に軸着する。アーム３６には前記株元引継搬送装置２４側に設けた当接部材３７を当接させる。したがって、扱深さ調節用モーター３２によりアーム３６を回動させると、穂先引継搬送装置２３および株元引継搬送装置２４の始端部を、穀稈身の方向に位置調節でき、株元側搬送装置１１からの穀稈を引き継ぐ位置を変更して扱深さを調節する構成である。即ち、株元引継搬送装置２４の始端部を低くして穀稈の根本側を挟持すると深扱き、株元引継搬送装置２４の始端部を高くして穀稈の穂先側を挟持すると浅扱きとなる。
前記穂先引継搬送装置２３は、前記縦取付部材３０にケース３８を取付け、該ケース３８内に搬送ラグ３９付きチエンまたはベルトの駆動機構を設けて構成される。また、前記株元引継搬送装置２４は無端状の穀稈引継搬送チエン４０と該穀稈引継搬送チエン４０の側部に遠近移動自在に設けられる挾扼杆４１とにより構成し、図示は省略するが、穀稈引継搬送チエン４０のチエン案内レールおよび駆動歯車等を前記縦取付部材３０に取付け、穀稈引継搬送チエン４０と挾扼杆４１とにより構成する穀稈搬送通路の上方を跨ぐように逆Ｕ型形状の取付杆４２の基部を前記穂先引継搬送装置２３のケース３８側に取付ける。取付杆４２の先端にはホルダ４３を固定する。ホルダ４３に前記挾扼杆４１を取付ける。
【０００９】
しかして、前記株元引継搬送装置２４の終端部には、穀稈供給装置２２の穀稈供給搬送チエン４４の始端部を臨ませ、穀稈供給搬送チエン４４の始端部の前記株元引継搬送装置２４側には補助引継装置５０を設ける。補助引継装置５０は前記横取付回転筒２９より側方に突出する回転横軸３１に駆動歯車５１を固定し、駆動歯車５１に対応する受動歯車５２を駆動歯車５１と前記脱穀装置３との間に設け、駆動歯車５１と受動歯車５２に補助引継チエン５３を掛け回す。前記受動歯車５２は、脱穀装置３側に基部を取付けた取付部材５４の先端に取付ける。そして、前記補助引継チエン５３の上方には引継ガイド５５を設け、前記補助引継チエン５３と引継ガイド５５とにより穀稈の株元側を挟持搬送して、穀稈供給装置２２に引き継ぐ。前記引継ガイド５５はどこに取付けても良いが、実施例では、株元引継搬送装置２４の挾扼杆４１の終端側に基部を取付けている。５６は前記穀稈供給装置２２の挾扼杆であり、前記穀稈供給搬送チエン４４の上方に臨ませる。
５７は前記脱穀装置３の脱穀室、５８は扱胴、５９は扱網、６０は風選室、６１は風選室６０内に設けた揺動選別装置、６２は送風ファン、６３は１番コンベア、６４は２番コンベア、６５は吸引排塵ファン、６６は前記２番コンベア６４より２番物を戻す２番物戻し装置、６７は処理装置の処理胴、６８は脱穀室５６の終端に接続させた排塵胴である。前記処理胴６７および排塵胴６８の周囲には処理網６９を設けるが、処理網６９は、処理胴６６および排塵胴６７の回転方向には同一の目とし、処理物の移送方向には交互に大の目７０と小の目７１となるように配置する。
【００１０】
また、前記揺動選別装置６０に設けた前記１番コンベア６２の上方の１番物選別網７２は、揺動方向には同一の目とし、揺動方向と交差する方向には交互に大の目７０と小の目７１となるように配置する。
７３は株元引継搬送装置２４と穂先引継搬送装置２３のそれぞれの始端部側を連結する連結部材、７４は変速装置（ＨＳＴ）、７５は脱穀室５７の上部カバーである。
【００１１】
【作用】
次に作用を述べる。
本発明は前記の構成であるから、機体を前進させると、各分草体５により分草し、分草穀稈は引起装置６により引き起され、引き起された穀稈は掻込装置７により掻き込まれて刈刃８により切断され、切断された穀稈の株元は株元側搬送装置１１により挟持搬送され、穂先は穂先側搬送装置１２により搬送され、穀稈の株元は株元引継搬送装置２４に引き継がれ、穂先は穂先引継搬送装置２３により搬送され、株元引継搬送装置２４により搬送された穀稈の根本は、起立姿勢から横向きになって、脱穀装置３の穀稈供給装置２２に引き継がれ、脱穀室に供給される。
【００１２】
そして、長穀稈の場合は、株元引継搬送装置２４の始端部を株元側搬送装置１１に対して上動させて挟持位置を上にして浅扱きとし、短穀稈の場合は、株元引継搬送装置２４の始端部を株元側搬送装置１１に対して下動させて挟持位置を下にして深扱きとするが、いずれも、株元引継搬送装置２４の挟持位置より穀稈の根本側は所定の長さを有し、株元引継搬送装置２４の終端に至ったとき穀稈供給装置２２の始端部で引継できるようにしている。
しかして、圃場の隅の枕地では、従来、手作業で穀稈を刈取り、これを穀稈供給装置２２に供給していたが、これを刈取部４により高刈りして脱穀装置３に供給すると、作業が簡単になるが、反面、穀稈の長さが短いので、株元引継搬送装置２４から穀稈供給装置２２への引継が不良となることがある。
【００１３】
本発明では、株元引継搬送装置２４の終端と穀稈供給装置２２の始端部との間に、穀稈供給装置２２と平行に補助引継装置５０を設けているから、短い穀稈の根本は、補助引継チエン５３と引継ガイド５５により挟持されて脱穀装置３に搬送される。したがって、穀稈供給装置２２の搬送こぼれがなくなって、ロスを防止する。
また、補助引継装置５０の補助引継チエン５３の駆動歯車５１は、横取付回転筒２９より側方に突出する回転横軸３１に取付けられているから、補助引継装置５０の回転伝達機構は頗る簡単である。また、駆動歯車５１は、穂先引継搬送装置２３および株元引継搬送装置２４の扱き深さ調節用の回動芯と同心の回転横軸３１に取付けているから、補助引継チエン５３は穂先引継搬送装置２３および株元引継搬送装置２４の扱き深さ調節の影響を受けず、また、扱き深さ調節に影響も与えない。
【００１４】
また、補助引継チエン５３の終端の受動歯車５２は、脱穀装置３側に基部を回動自在に取付けた取付部材５４の先端に取付けているから、刈取部４の上下にも対応し得る。
また、補助引継装置５０は、刈取部４側より回転を伝達する構成であり、受台１６側に取付け、穀稈供給装置２２と無関係に取付けてあるから、穀稈供給装置２２の設計の自由度を高め、機体に対して穀稈供給搬送チエン４４を開く構成にすることができ、メンテナンスを容易にする。
また、刈取部４に伝達する回転により補助引継装置５０を作動させるから、補助引継装置５０は刈取部４と連動し、制御を容易にし、また、圃場のコーナーでの引継の稈こぼれを解消させる。
【００１５】
しかして、前記処理胴６６および排塵胴６７の周囲には処理網６８を設けるが、処理網６９は、処理胴６６および排塵胴６７の回転方向には同一の目とし、処理物の移送方向には交互に大の目６９と小の目７０となるように配置しているから、藁屑、かぎまたの未処理物の漏下を防止して、穀粒の漏下を促進させ、選別精度を向上させ、ロスを減少させる。
また、前記揺動選別装置６０に設けた前記１番コンベア６２の上方の１番物選別網７１は、揺動方向には同一の目とし、揺動方向と交差する方向には交互に大の目６９と小の目７０となるように配置しているから、藁屑、かぎまたの漏下を防止して、穀粒の漏下を促進させ、２番還元を減少させ、脱穀性能を向上させる。
【００１６】
【効果】
本発明は、刈刃８および刈刃８により刈取った穀稈を搬送する搬送装置１１を有し上下回動自在に設けた刈取部４と、該刈取部４の後方に設けた脱穀装置３に穀稈の穂先側を供給する穀稈供給装置２２と、前記刈取部４と前記穀稈供給装置２２との間に設けられ、穀稈引継搬送チエン４０および挾扼杆４１とからなりその始端部を前記搬送装置１１の終端に対して遠近変更自在に構成した引継搬送装置２４とを設けたコンバインにおいて、前記穀稈供給装置２２の始端部の前記引継搬送装置２４側の側部には、前記穀稈供給装置２２と平行であって補助引継チエン５３と引継ガイド５５とにより穀稈の株元側を挟持搬送する補助引継装置５０を設け、該補助引継チエン５３の始端側の駆動歯車５１は前記引継搬送装置２４が前記搬送装置１１の終端に対して上下回動するときの回動中心となる回転横軸３１に設け、前記補助引継チエン５３の終端側の受動歯車５２は前記脱穀装置３側に基部を回動自在に取付けた取付部材５４の先端に取付けたコンバインの補助引継装置としたものであるから、短穀稈であって、穀稈供給装置２２で確実に搬送できない場合でも、その根本を、補助引継チエン５３と引継ガイド５５により挟持して脱穀装置３に搬送供給できる。したがって、穀稈供給装置２２の搬送こぼれがなくなって、ロスを防止する。
また、駆動歯車５１は、株元引継搬送装置２４の扱き深さ調節用の回動芯と同心の回転横軸３１に取付けているから、補助引継チエン５３は株元引継搬送装置２４の扱き深さ調節の影響を受けず、また、扱き深さ調節に影響も与えない。
また、補助引継チエン５３の終端の受動歯車５２は、脱穀装置３側に基部を回動自在に取付けた取付部材５４の先端に取付けているから、刈取部４の上下にも対応できる。
本発明は、前記刈取部４は、前記刈刃８および前記株元側搬送装置１１を設けた刈取部フレーム１３に、基部を機体フレーム１に回動自在に設けた刈取支持部材１４の先端を固定し、該刈取支持部材１４の基部には刈取入力プーリー１９を一端に固定した回転伝達軸１８を軸装した横伝動回転筒１５を設け、該横伝動回転筒１５の他端側に設けた伝動ケース２７に、前記回転伝達軸１８の回転により回転する回転横軸３１を軸装した横取付回転筒２９の基部を回転自在に取付け、該横取付回転筒２９の中間部に前記株元引継搬送装置２４を設け、前記横取付回転筒２９より突出する回転横軸３１に前記駆動歯車５１を設けたコンバインの補助引継装置としたものであり、補助引継装置５０は、横取付回転筒２９に取付け、穀稈供給装置２２と無関係に取付けてあるから、穀稈供給装置２２の設計の自由度を高め、機体に対して穀稈供給搬送チエン４４を開く構成にすることができ、メンテナンスを容易にする。また、補助引継装置５０の補助引継チエン５３の駆動歯車５１は、横取付回転筒２９より側方に突出する回転横軸３１に取付けられているから、補助引継装置５０の回転伝達機構は頗る簡単である。また、刈取部４に伝達する回転により補助引継装置５０を作動させるから、補助引継装置５０は刈取部４と連動し、制御を容易にし、また、圃場のコーナーでの引継の稈こぼれを解消させる。
