Description

【０００１】
【発明の属する技術分野】
この発明は、コンバインの刈取部に関するものである。
【０００２】
【従来の技術】
従来、特開平６−３０３８３５号公報に開示されている通り、コンバインの走行車体側の前部上位に横軸まわりに枢着されて油圧シリンダ−装置で上下動される斜伝動ケ−スの前方下端側に横方向に延びる伝動筒ケ−スを固着し、この伝動筒ケ−スの左右一側部側から立設の伝動ケ−スによって穀稈移送装置を伝動し、他側から立設の伝動ケ−スを穀稈引起ケ−スの高さよりも高く伸ばし、その上端側に横方向に延びる横筒ケ−スを設け、この横筒ケ−スから各引起ケ−ス側の入力軸を駆動する吊下伝動ケ−スを設けた構成のものがあった。
【０００３】
【発明が解決しようとする課題】
前述の従来技術では、穀稈引起装置側の変速機構が設けられていなかった為に、刈取穀稈の倒伏状態や成育状態あるいは稲、麦の差異等に応じた適性な引起しが困難であった。また、変速機構を装備する位置が穀稈の背丈よりも低い位置に構成した場合には、刈取穀稈を脱穀機側へ移送する通路の邪魔になり、特に、刈取部を横移動可能なものにした場合には変速機構を内装するケ−スが固定側の他の部材と緩衝する等の事態が起こり、この変速機構内装のケ−スの配置が設計上大きな問題になった。
【０００４】
【課題を解決するための手段】
この発明は、前述の課題を解消するために次の技術的な手段を講じた。
【０００５】
即ち、車体前部の下位側に位置して左右横方向に延びる伝動軸を包んだ第１筒型横伝動ケ−ス８の左右中間部の外周を覆って当該第１筒型横伝動ケ−ス８を左右に移動自在に支持する覆筒メタル１０を設け、この覆筒メタル１０に先端側が固着されて後方上側へ延びる傾斜状の伝動軸を内装する斜伝動ケ−ス１５を設け、この斜伝動ケ−ス１５の上端側を、エンジン４及び脱穀装置２等を取り付けた車体１の前側上位で横方向の軸心まわりに回動自由に枢着し、この車体１側と斜伝動ケ−ス１５との間に油圧シリンダ−装置９６を介装して該刈取部側が昇降作動されるよう構成すると共に、前記覆筒メタル１０と第１筒型横伝動ケ−ス８との間に第１筒型横伝動ケ−ス８を適宜操作指令により左右方向へ移動させる移動機構を介在し、前記斜伝動ケ−ス１５内に伝動軸１６を軸受して該伝動軸１６に駆動ベベルギヤ−１２を取り付ける一方、前記第１筒型横伝動ケ−ス８の内部に伝動軸９を軸受支持し、該伝動軸９に対して前記駆動ベベルギヤ−１２と噛み合う従動ベベルギヤ−１４を摺動自在に嵌合し、前記第１筒型横伝動ケ−ス８に穿った左右横方向に長い孔１３から前記駆動ベベルギヤ−１２を該第１筒型横伝動ケ−ス８内に挿入して該駆動ベベルギヤ−１２を前記従動ベベルギヤ−１４と噛み合わせて、前記覆筒メタル１０に対して第１筒型横伝動ケ−ス８が左右に移動しても、伝動軸９に嵌合の従動ベベルギヤ−１４と駆動ベベルギヤ−１２との噛み合い状態がそのまま保持され、且つ、第１筒型横伝動ケ−ス８に穿った孔１３が覆筒メタル１０からはみ出さないよう構成し、前記第１筒型横移動ケ−ス８の横端側から刈刃装置１９を駆動するクランク機構２４を設けるに、前記伝動軸９の端部に取り付けた駆動ベベルギヤ−２５と該駆動ベベルギヤ−２５に噛み合うベベルギヤ−２６とで駆動される垂直軸２７の上端部を偏心させてクランク機構２４を構成し、また、同じく横端側一側部には刈取穀稈の後方側への移送を行なう第１穀稈移送装置２９ａの伝動及び穀稈引起装置６４側の伝動を行なう第１縦伝動軸３７を内装する第１縦伝動筒ケ−ス３８を立設して前記第１縦伝動軸３７を前記第１筒型横伝動ケ−ス８内の伝動軸９から一対のベベルギヤ−３５，３６を介して伝動するように構成し、他側部側には第２穀稈移送装置２９ｂを駆動する第２縦伝動軸５３を内装した第２縦伝動筒ケ−ス５４を立設し、前記第１縦伝動筒ケ−ス３８の上方部位置に適宜操作で変速可能な変速装置Ａを内装した変速伝動ケ−ス４１を設け、この変速装置Ａで変速される出力軸４７で駆動される前記穀稈引起装置６４側を駆動する左右方向に長い横軸６９を内装する第２筒型横伝動ケ−ス７０を穀稈引起ケ−ス６６の上端よりも高くなる位置に横設し、前記第１筒型横伝動ケ−ス８に、当該第１筒型横伝動ケ−ス８の左右両端側部から前方に向けて縦突起枠１７ａ，１７ｂを設けてこの左右縦突起枠先端側を横枠１７ｃで連結した下部フレ−ム１７を設け、この下部フレ−ム１７の横枠１７ｃから先端側に分草体１８ａを取り付ける分草取付杆１８ｂを左右側に所定間隔で取付け、この分草取付杆１８ｂに穀稈引起ケ−ス６６の下部側を取付けると共に、前記第２筒型横伝動ケ−ス７０から前記左右側に並設の各穀稈引起ケ−ス６６の上部側を前記第２筒型横伝動ケ−ス７０から下方へ向けて突出させた吊下伝動ケ−ス７４に連結し、該第２筒型横伝動ケ−ス７０内の前記横軸６９から吊下伝動ケ−ス７４内の伝動部材を介して穀稈引起装置６４を駆動するよう設け、前記第１筒型横移動ケ−ス８と、穀稈引継移送装置７９を扱深調節するサ−ボモ−タ１００を取り付けたア−ム９８とをロッド９９で連動して、刈取部側を左右に移動調節するとき穀稈引継移送装置７９側も左右側へ回動して刈取穀稈が刈取部側から穀稈引継移送装置７９側に引き継がれるように構成したことを特徴とするコンバインの刈取部とした。
【０００６】
【発明の効果】
この発明によれば、稲、麦等の収穫時に、その穀稈を引起しながら刈取作業をするが、作物の成育状態や倒れ状態あるいは品種、稲麦の違いに応じて、穀稈引起速度を切り換えて的確な作業ができるものでありながら、この引起速度を切り換える変速装置が引起装置の後方側の高い位置に装備してあり、この引起装置側への動力伝達が引起装置の上端よりも高い位置に設けた横方向の伝動軸から各引起装置の背面側上部へ垂下ならしめた伝動軸で作動させる構成としたから、引き起こされた穀稈の背丈が大きくとも難なく後方側へ通過でき、また、前記変速装置もその穀稈移送には邪魔にならないで穀稈移送がスム−ズに行なえる。
【０００７】
また、刈取部を左右に位置調節する場合には、第１筒型横伝動ケ−スを左右側に移動させることで簡単に調節でき、畦際に沿って作業する場合に便利である他、穀稈列が左右に変化している場合にも利用できる。
【０００８】
また、刈取部側を左右横移動させても、穀稈引継移送装置がこの移動に合わせて回動され、刈取穀稈の引継ぎを行うことができる。
【０００９】
【発明の実施の形態】
この発明の一例を図面に基づき詳細に説明する。
【００１０】
１は走行車体で、左右側下部に無限軌道帯を装備した走行装置が設けられている。
【００１１】
２は脱穀装置で、前記走行車体１の上部に搭載されている。３は脱穀装置２の脱穀チエンで、脱穀装置２の脱穀室に送り込まれる穀稈の株元を挾扼して搬送するもので脱穀機の扱ぎ口に沿って張設されている。
【００１２】
４はエンジンで、前記走行車体１の右側より前部に搭載され、この上部に操縦座席５は設けられている。６はミッションケ−スで、走行車体１の前側で左右中間部に配置され、この上側に伝動機構を内装する立設枠７を設けている。
【００１３】
８は第１筒型横伝動ケ−スで、内部に断面六角形状の伝動軸９が左右端側で軸受支持されている。１０は覆筒メタルで、第１筒型横伝動ケ−ス８の左右中間部を覆うよう該ケ−ス８に摺動自在に嵌合されており、このメタル１０側に一体の軸受体１１に駆動ベベルギヤ−１２を設け、前記ケ−ス８に穿った左右横方向に長い孔１３から軸受体１１及びベベルギヤ−１２がケ−ス８内に挿入されていて、前記軸受体１１で回転自在に軸受されて前記ベベルギヤ−１２と噛み合う従動ベベルギヤ−１４を前記伝動軸９に摺動自由に嵌合し、覆筒メタル１０に対して第１筒型横伝動ケ−ス８が左右に移動しても伝動軸９に嵌合の従動ベベルギヤ−１４と駆動ベベルギヤ−１２との噛み合い状態がそのまま保持され、また、ケ−ス８に穿った孔１３は覆筒メタル１０からはみ出さないよう構成されている。従って、伝動軸９の駆動は、第１筒型横伝動ケ−ス８を移動させている途中でも伝動できる状態を保持することになる。
【００１４】
１５は斜伝動ケ−スで、基部側を前記立設枠７に横方向の軸心まわり回動可能に取付け、先端部側を前記覆筒メタル１０に一体状に取り付けた前記軸受体１１に固着している。そして、この斜伝動ケ−ス１５内には、前記ミッションケ−ス６側から駆動される伝動軸１６を内装して軸受し、この軸１６に前記駆動ベベルギヤ−１２が取り付けられている。
【００１５】
１７は下部フレ−ムで、基部側を前記第１筒型横伝動ケ−ス８の左右両側下部に固着されて前方へ突出する縦突起枠１７ａ，１７ｂとこの両縦突起枠１７ａ，１７ｂの先端側を連結する横枠１７ｃとで構成されている。
【００１６】
１８は分草枠で、前端側に圃場の穀稈を走行に伴い左右へ分けるよう平面視が三角状になっていて前端側が下位に後端側が上位に形成された分草体１８ａとこの分草体１８ａを先端部に取り付けて後方側へ延びる棒状杆１８ｂとで構成されている。
【００１７】
この分草枠１８を前記下部フレ−ムの横枠１７ｃに左右所定の間隔で固着し、この分草体１８ａが圃場の穀稈列の間を通るよう設けられている。
【００１８】
１９は刈刃装置で、前記横枠１７ｃの前側に横設され、上刃２０と下刃２１が重ね合わされて設けられている。この上、下の両刃を互いに反対の左右横端側をＬ字レバ−２２で格別に駆動される構成になっている。２３は刃押えである。
【００１９】
２４はクランク機構で、前記第１筒型横伝動ケ−ス８の左右両端側にあって、前記伝動軸９の端部に取り付けた駆動ベベルギヤ−２５とこれに噛み合うベベルギヤ−２６とで駆動される垂直軸２７の上端部を偏心させて構成し、このクランク機構２４と前記Ｌ字レバ−２２とをロッド２８で連動して刈刃装置１９を駆動するよう構成している。
【００２０】
２９ａは刈取穀稈を後方側へ掻き集めて移送する第１穀稈移送装置で、穀稈を挾扼搬送する挾扼移送チエン３０とその移送中の穀稈の穂先部を係止搬送する上側ラグ付移送チエン３１と下側ラグ付移送チエン３２及び挾扼移送チエン３０の前側下部に設けた掻込歯車３３、その上側に位置させたラグ付ベルト３４とから構成されている。即ち、この第１穀稈移送装置２９ａの伝動構成は、前記第１筒型横伝動ケ−ス８の左端側寄りから一対のベベルギヤ−３５、３６で前記伝動軸９から伝動されて上方側へ立設する第１縦伝動軸３７を覆う第１縦伝動筒ケ−ス３８の上下中間部に前記第１縦伝動軸３７から伝動を受けて該第１縦伝動軸３７から内方へやや寄った位置に上方へ向かう出力軸３９を設け、この伝動機構部を中間伝動ケ−ス４０で内装させている。尚、前記出力軸３９は、伝動ケ−ス４０の下側に向けて突出させて後述のスプロケット４９を該伝動ケ−ス４０の下側に配置してもよい。
【００２１】
４１は変速伝動ケ−スで、前記第１縦伝動筒ケ−ス３８の上端側に取り付けられ、このケ−ス４１内には変速装置Ａが内装されている。即ち、前記第１縦伝動軸３７に楔着された２連の大駆動ギヤ−４２と小駆動ギヤ−４３とが設けられ、この両ギヤ−にシフタ−４４で選択的に噛み合わせることができる小従動ギヤ−４５及び大従動ギヤ−４６がスプライン軸部（イ）に摺動自在に嵌合されていて、こスプライン軸部（イ）を有する出力軸４７を上側に突出ならしめている。即ち、前記シフタ−４４を操作する変速レバ−４８の操作で出力軸４７を２段階に変速可能に構成している。
【００２２】
前記出力軸３９には、前記挾扼移送チエン３０を回転駆動するスプロケット４９を設け、前記第１縦伝動筒ケ−ス３８側から挾扼移送チエン３０の巻掛従動スプロケットを軸受するフレ−ム兼用のチエンケ−ス５０を設け、更に、前記横端の分草体１８側から補強枠５１を設けて強固に構成している。この挾扼移送チエン３０の前側上側には穀稈掻込ベルト装置３４を、また下側には穀稈掻込歯車３３を設けている。これらの動力伝達は、前記挾扼移送チエン３０の従動スプロケット取付け軸から得られるよう構成されている。上側ラグ付移送チエン３２と下側ラグ付移送チエン３１は、前記挾扼移送チエン３０の従動スプロケットを軸受する筒フレ−ム５１，５２で支持されている。
【００２３】
２９ｂは刈取穀稈を後方側へ掻き集めて移送する第２穀稈移送装置で、前記第１穀稈移送装置２９ａとは反対側に位置し、第１筒型横伝動ケ−ス８の右端側に立設させた第２縦伝動軸５３を覆う第２縦伝動筒ケ−ス５４を設け、前記第２縦伝動軸５３の上側にスプロケット５５を設けて、これに左側に設けた穀稈を挾扼搬送する挾扼移送チエン５６とその移送中の穀稈の穂先部を係止搬送する上側ラグ付移送チエン５７と下側ラグ付移送チエン５８及び挾扼移送チエン５６の前側下部に設けた掻込歯車５９、その上側に位置させたラグ付ベルト６０とを前記第１穀稈移送装置２９ａと略同様な技術形態で構成している。
【００２４】
６１は従動掻込歯車で前記駆動掻込歯車３３に噛み合わせている。６２は小径従動掻込歯車で前記駆動掻込歯車５９に噛み合わせている。６３は掻込歯車６１の上側に設けたラグ付ベルトである。
【００２５】
６４は穀稈引起装置で、上側の駆動スプロケットと下側の従動スプロケットとの間にチエンを巻回し、該チエンに穀稈引起爪６５を起伏自在に設け、この引起爪６５が一側面側では起立突出するようケ−ス６６で覆っている。そして、この穀稈引起装置６４をやや下位側が前になるよう傾斜させて設け、引起ケ−ス６６の背面下位を前記分草枠１８に固着している。そして、前記変速機構Ａを介して駆動される出力軸４７により一組みのベベルギヤ−６７，６８で伝動される横軸６９を第２筒型横伝動ケ−ス７０内に納め、この横軸６９から一組みのベベルギヤ−７１，７２で下向きの吊下伝動軸７３を吊下伝動ケ−ス７４に内装軸受させ、この下端側に一組みのベベルギヤ−７５，７６を設けて前記穀稈引起装置６４の引起チエン駆動軸７７を伝動する。そして、該吊下伝動ケ−ス７４の下端側を引起ケ−ス６６のに前記ベベルギヤ−７５，７６を内装するベベルギヤケ−ス７８を介して取付ける。
【００２６】
７９は穀稈引継移送装置で、前記斜伝動ケ−ス１５の基部側を横方向軸の軸心（ハ）まわりに回動自在に枢支する回動メタル８０に一体状に構成された伝動軸を内装の突出筒８１を設け、この突出筒８１の上側に当該筒８１内の駆動軸の軸心（ニ）を中心にして回動自在なベベルギヤケ−ス８２を設け、該ケ−ス８２の横一側に突出して横軸心（ホ）の回りに回動自在な側面視はＴ字状をした伝動ケ−ス８３を設け、このケ−ス８３の上下方向に向かうケ−スの上部及び下部に突出する駆動軸８４にそれぞれスプロケット８５，８６を取り付けている。
【００２７】
そして、この下側の駆動スプロケット８６と前記伝動ケ−ス８３から前側に突出させた伝動フレ−ム８７の先端側及び前後中間部側に軸架させた従動スプロケット８８，８９，９０との間に穀稈移送チエン９１を掛け回して株元引継ぎ移送装置を構成している。また、前記駆動スプロケット８５と前記伝動フレ−ム８７側に設けられた従動スプロケット９２との間にはラグ付き穂先係合移送チエン９３を掛け回して穂先引継ぎ移送装置を構成している。即ち、穀稈引継移送装置７９は、株元引継ぎ移送装置７９ａと穂先引継ぎ移送装置７９ｂとで構成される。
【００２８】
前記穂先引継ぎ移送装置７９ｂの穂先係合移送チエン９３は移送ラグ（ロ）が突出する移送機能側においては穀稈がチエンに接触して穀稈巻きつきの原因になるため上下チエンカバ−が必要であるが、穀稈を移送しない非作用面側では下側のチエンカバ−が設けられているとチエンケ−ス内に入ったわら屑がケ−ス内に停滞してチエンの走行を妨げることになる。そこで、この実施例では、チエンケ−ス９４の非作用面側における下面側を欠如させたチエンケ−ス下９４ａとなし、わら屑が自由落下するよう構成している。また、該チエンケ−ス９４の下側には前記株元引継ぎ移送装置７９ａの穀稈移送チエン９１が走行する構成になるが、前記チエンケ−ス９４を欠如させてわら屑を自由落下ならしめる下側に株元側を移送するチエンが位置すると、この下側チエン上に落下してきたわら屑が載って走行しわら屑巻きつきの原因になることから、当該穀稈移送チエン９１がわら屑落下位置の真下にならないように前記従動輪９０を設けて該穀稈移送チエン９１の非作用面側の走行ラインを内側寄りに屈曲させて逃がした構成としている。尚、前記穂先引継ぎ移送装置７９ｂの穂先係合移送チエン９３はの巻掛状態はラグ（ロ）が穀稈穂先部側を係合して移送する側が水平面に対して高く、逆に非作用面側が低くなるよう左右側にも傾斜させている。
【００２９】
９５はエンジン４側から動力伝達される入力プ−リを示す。
【００３０】
９６は昇降用油圧シリンダ−装置で、車体１と前記斜伝動ケ−ス１５との間に設けられていて、穀稈引継移送装置７９及び刈取装置側を軸心（ハ）回りに回動させて昇降作動するよう構成している。
【００３１】
９７は刈取部横移動用の油圧シリンダ−装置で、斜伝動ケ−ス１５と第１筒型横伝動ケ−ス８側との間に設けられていて、第１筒型横伝動ケ−ス８を左右に移動調節出来るよう構成している。また、このシリンダ−装置のピストンロッド先端側あるいは移動する伝動ケ−ス８と前記ベベルギヤケ−ス８２に一体的に基部側を取り付けて前方側へ突出させたア−ム９８とをロッド９９で連動し、刈取部側を左右に移動調節するとき、穀稈引継移送装置７９側が軸心（ニ）回りに左右側へ回動して前記挾扼移送チエン３０及びラグ付移送チエン３１，３２で移送された穀稈が穀稈引継移送装置７９側に確実に引き継がれるよう連動構成している。
【００３２】
１００は扱深調節用のサ−ボモ−タで、前記ア−ム９８側に取り付けられており、該モ−タの駆動軸に取り付けた回動ア−ム１０１と前記伝動ケ−ス８３に一体のア−ム１０２とロッド１０３で連結して軸心（ホ）の回りにケ−ス８３を回動調節でき、脱穀チエン３へ穀稈を受渡す場合に株元側の挾持位置が調節できるように構成している。
【００３３】
上例の作用について詳細に説明すると、エンジン４で各部を駆動し、刈取部を下降させて走行車体１を推進しながら刈取脱穀作業を開始する。
【００３４】
刈取部側の駆動は、入力プ−リ９５により駆動される。即ち、入力プ−リ９５で駆動される軸から一組みのベベルギヤ−を介して傾斜伝動ケ−ス１５内に設けられた軸１６が駆動されると共に、入力プ−リ９５で駆動される軸からケ−ス８０内の他の一組みのベベルギヤ−及びケ−ス８２内の一組みのベベルギヤ−及びそれぞれの軸からケ−ス８２内の横軸が駆動され、且つ、外軸から一組みのベベルギヤ−で軸８４が駆動される。
【００３５】
そして、軸１６からベベルギヤ−１２，１４を介して横軸９が駆動され、第１筒型横伝動ケ−ス８の横端に設けたクランク機構２４が伝動され、このクランク機構２４から刈刃装置１９が駆動される。
【００３６】
一方、横軸９からベベルギヤ−を介して左右側に立設する縦方向の軸３７，５３を伝動回転ならしめ、第１穀稈移送装置２９ａと第２穀稈移送装置２９ｂとを伝動する。また、軸３７の上部側には変速装置Ａを介して出力軸４７を駆動し、ベベルギヤ−６７，６８を介して第２筒型横伝動ケ−ス７０内の横軸６９を駆動する。そして、この横軸６９から下側に吊り下がる吊下伝動ケ−ス７４内の伝動軸７３を一組みのベベルギヤ−７１，７２を介して伝動し、下側端からベベルギヤ−７５，７６を介して引起チエン駆動軸７７を伝動し、この軸７７に固着のスプロケットにより穀稈引起装置６４を駆動する。
【００３７】
したがって、圃場の稲、麦等の穀稈は、分草体１８ａで分草されながら引起装置６４で引き起こされ、その後に刈刃装置１９で刈り取られると共に、前記軸３７及び軸５３で駆動される第１穀稈移送装置２９ａと第２穀稈移送装置２９ｂにより株元側が挾扼移送チエン３０，５６でキャッチングされ、穂先側がラグ付移送チエン３１，３２，５７，５８で係止されながら後方上部へ移送される。そして、後方上部に位置する穀稈引継移送装置７９に引き継がれる。即ち、株元側は穀稈移送チエン９１で引き継がら、穂先側は穂先係合移送チエン９３で引き継がれて後方上方へ移送されて行く。このとき、株元側を左端側上方へ高く引上げて移送中の穀稈を横寝さし状態に姿勢変更させ、この状態で株元側を脱穀チエン３に受け継ぎ、穂先側を脱穀機２の扱室内へ供給する。このようにして刈取脱穀作業が行なわれる。
【００３８】
このような穀稈を分草して刈り取るまでの行程において、穀稈を引起装置６４で引き起こす場合、穀稈の倒れ状態や成育状態等で該穀稈引起装置６４の引起速度を変更することが要求されるが、この場合には、前記変速装置Ａを切替操作して、穀稈の倒れがひどい場合やわら屑の多い成育状態のような場合には、引起速度を高速に切れ変えへ作業する。逆に、倒れていない穀稈や背丈の低い穀稈のような場合に低速で引き起こすように切換える。また、麦の収穫作業では、穀稈引起速度が速いと、穀稈を引きちぎる恐れが多いために引起速度を低速側に切り換えて作業をする。
【００３９】
扱深さ調節は、伝動ケ−ス８３を軸心（ホ）の回りに回動調節して任意に設定することで、脱穀チエン３に株元側を受け継がせる位置を変更して行なう。尚、自動扱深調節をする場合には、サ−ボモ−タ１００を移送中の穀稈の穂先位置検出センサ−で検出し、その穂先の位置に応じて該モ−タ１００を正転あるいは反転させることで自動化させることができる。
【００４０】
また、走行車体１に対して刈取装置側を左右に位置調節する場合には、油圧シリンダ−装置９７を油圧切替バルブ（図示省略）で切替て第１筒型横伝動ケ−ス８を左右側に移動させることで簡単に調節できる。これは、畦際に沿って推進作業する場合に便利である他、穀稈列が左右に変化しているような場合にも利用できる。尚、この油圧シリンダ−装置９７は電動式シリンダ−であっても差し支えなく、また、自動的に穀稈列を検出して刈取部側を左右移動制御することもできる。
【００４１】
この刈取装置側を左右に横移動調節するとき、穀稈移送装置２９から穀稈引継装置７９への穀稈受け継ぎを確実にするために、ロッド９９を介してア−ム９８を作動する。即ち、このア−ム９８によりケ−ス８３及びベベルギヤ−ケ−ス８２を軸心（ニ）回りに回動させ、常に所定の関係を保持する。したがって、油圧シリンダ−装置９７で刈取部側を左右横移動させて適所に設定しても、穀稈引継移送装置７９がこの移動に合わせて回動設定され、常に確実な引継ぎが行なわれる。
【００４２】
穀稈引継移送装置７９の穂先側移送装置７９ｂ側の穂先係合移送チエン９３をカバ−するチエンケ−ス９４において、その上側チエンケ−スに対する下側ケ−ス９４ａがラグ突出の作用側を残して、反対側を欠如させた構成とするため、穀稈係合移送の非作用側でわら屑が自然に自由落下し、従来のチエン全体をカバ−するものに比較してわら屑の巻きつきやケ−ス内停滞がなく詰まりによる移送不能やチエンケ−ス破損が防止できる。
【００４３】
また、この穂先係合移送チエン９３の下側に位置して株元側を挾扼移送する穀稈移送チエン９１に、落下するわら屑が降りかからないようにチエン走行ラインを逃がした構成とすることで、該移送チエン９３にもわら屑がひっかからず確実な移送を行なうことができる。

It is configured to be able to.
[0033]
Explaining the operation of the above example in detail, the respective parts are driven by the engine 4, the reaping section is lowered, and the reaping and threshing work is started while the traveling vehicle body 1 is propelled.
[0034]
The mowing unit is driven by the input pulley 95. That is, a shaft 16 provided in the inclined transmission case 15 is driven from a shaft driven by the input pulley 95 via a set of bevel gears, and a shaft driven by the input pulley 95. The other set of bevel gears in the case 80 and the set of bevel gears in the case 82 and the respective shafts drive the horizontal axis in the case 82 and one set from the outer shaft. The shaft 84 is driven by the bevel gear.
[0035]
Then, the horizontal shaft 9 is driven from the shaft 16 via the bevel gears 12 and 14, and the crank mechanism 24 provided at the lateral end of the first cylindrical horizontal transmission case 8 is transmitted. The device 19 is driven.
[0036]
On the other hand, the vertical shafts 37 and 53 erected on the left and right sides from the horizontal shaft 9 via bevel gears are transmitted and rotated to transmit the first grain culm transfer device 29a and the second grain culm transfer device 29b. On the upper side of the shaft 37, the output shaft 47 is driven via the transmission A, and the horizontal shaft 69 in the second cylindrical lateral transmission case 70 is driven via bevel gears 67, 68. A transmission shaft 73 in a suspension transmission case 74 suspended downward from the horizontal shaft 69 is transmitted through a pair of bevel gears 71 and 72, and from the lower end through bevel gears 75 and 76. Thus, the raising shaft 64 is transmitted to drive the cereal stem raising device 64 by a sprocket fixed to the shaft 77.
[0037]
Therefore, the culm of rice, wheat or the like in the field is raised by the raising device 64 while being weeded by the weeding body 18a, then cut by the cutting blade device 19, and driven by the shaft 37 and the shaft 53. The stem side is caught by the pinch transfer chains 30, 56 by the first culm transfer device 29a and the second culm transfer device 29b, and the spike side is moved to the upper rear while being locked by the lag transfer chains 31, 32, 57, 58. Be transported. And it is taken over by the grain culm transfer device 79 located in the upper rear part. That is, the root side is taken over by the grain culm transfer chain 91, and the tip side is taken over by the tip engagement transfer chain 93 and transferred upward and rearward. At this time, the root of the stock is pulled up to the upper left end side to change the posture of the culm being transported to the sideways state. In this state, the root of the stock is transferred to the threshing chain 3 and the tip side of the threshing machine 2 Supply into the handling room. Thus, the cutting and threshing operation is performed.
[0038]
In the process up to weeding and cutting the cereal stem, when raising the cereal stem with the raising device 64, the raising speed of the cereal stem raising device 64 may be changed depending on the falling state or the growing state of the cereal stem. In this case, it is required to switch the transmission A to change the raising speed to a high speed in a case where the culm is severely sloping or in a growing state with a lot of straw waste. I do. Conversely, it is switched so as to cause the culm not falling down or the culm having a short height at a low speed. In the wheat harvesting operation, when the cereal stem raising speed is high, the cereal stem is likely to be torn off.
[0039]
The handling depth is adjusted by rotating the transmission case 83 around the shaft center (e) and arbitrarily setting the position so that the threshing chain 3 can inherit the stock side. In the case of automatic depth adjustment, the servomotor 100 is detected by a sensor for detecting the position of the tip of the culm being transported, and the motor 100 is rotated forward or forward according to the position of the tip. It can be automated by inverting it.
[0040]
In order to adjust the position of the reaper to the left and right with respect to the traveling body 1, the hydraulic cylinder device 97 is switched by a hydraulic switching valve (not shown) to move the first cylindrical lateral transmission case 8 to the left and right. It can be easily adjusted by moving to. This is convenient when the propulsion work is performed along the ridge, and can also be used when the culm row is changing from side to side. Note that the hydraulic cylinder device 97 may be an electric cylinder, and it is also possible to automatically detect the grain culm row and control the lateral movement of the reaping unit side.
[0041]
The arm 98 is actuated via the rod 99 to ensure the transfer of the grain stalk from the grain stalk transfer device 29 to the grain stalk takeover device 79 when the reaping device side is laterally adjusted. That is, the arm 98 rotates the case 83 and the bevel gear case 82 around the axis (d) so as to always maintain a predetermined relationship. Therefore, even if the mowing part side is moved to the right and left by the hydraulic cylinder device 97 to set it at an appropriate position, the grain culm transfer device 79 is set to rotate in accordance with this movement, and a reliable transfer is always performed.
[0042]
In the chain case 94 which covers the tip engagement transfer chain 93 on the tip side transfer device 79b side of the grain culm transfer device 79, the lower case 94a with respect to the upper chain case leaves the working side of the lug protrusion. Therefore, since the opposite side is absent, the straw chips naturally fall freely on the non-working side of the grain culm engagement transfer, and the straw chips are wrapped around as compared with the conventional one that covers the entire chain. There is no stagnation in the case and no transfer due to clogging or breakage of the chain case can be prevented.
[0043]
In addition, the chain running line is allowed to escape to the grain stem transfer chain 91, which is located below the tip engagement transfer chain 93 and clamps and transfers the root of the stock, so that falling straw chips do not fall. Thus, the transfer chain 93 can be reliably transported without being caught by straw waste.
