Description

【０００１】
【発明の属する技術分野】
この発明は、コンバインやハーベスタ等の脱穀装置に関する。
【０００２】
【従来の技術】
従来のコンバインやハーベスタ等の脱穀装置は、扱室の一側に扱室から送られてくる排塵物を処理する排塵処理室を設け、その終端部から放出される排塵物は、揺動棚上に落下するか、又は、横断流ファンに吸引されて機外へと放出される構成である。
【０００３】
【発明が解決しようとする課題】
前述のようなコンバインやハーベスタ等の脱穀装置は、特に、脱穀装置に投入される穀稈が多くなると、当然扱室から排塵処理室へ送られる排塵物の量は多くなり、すると、揺動棚上に落下する排塵物も多くなるので、揺動棚上での選別能力が低下し、最悪の場合、揺動棚の選別能力の限界を越えてしまって揺動棚が破損するというような欠点があった。
【０００４】
本発明は、このような問題点を解消しようとするものである。
【０００５】
【課題を解決するための手段】
この発明に係るコンバインやハーベスタ等の脱穀装置は、前記のような課題を解決するものであって、次のような構成である。
【０００６】
すなわち、第１の手段として、脱穀装置１内に設けられた扱室２内には、フィードチェン３によって送られてきた穀稈を脱穀処理する扱胴４を軸架し、扱室２の一側には脱穀物を処理する処理胴５を内部に軸架する処理室６を設けると共に、該処理室６の後方には、前記処理胴５と同軸で一体的に回転して、扱室２の後部から送られてくる排塵物を処理する排塵処理胴７の架設されている排塵処理室８を設け、前記扱室２と処理室６と排塵処理室８の下方には落下してくる脱穀物を受けて選別する揺動棚９を設け、該揺動棚９の下方位置で選別風送り方向の始端側には唐箕１０を設け、選別風送り方向下手側に一番ラセン１１を、該一番ラセン１１の選別風送り方向下手側に二番ラセン１２をそれぞれ設け、前記排塵処理胴７の終端部には排塵物を拡散する拡散手段１３を設け、該拡散手段１３にて拡散された排塵物を直接機外に案内して放出する排塵通路１４を排塵処理室８の終端部に連通して脱穀装置１とグレンタンク２６の間の空間部を通過して後方の機外へ延出して設けて、二番ラセン１２内に取り込まれた二番物が二番揚穀筒３３にて処理室６の選別風送り方向下手側に還元されて扱室２からの脱穀物と合流し選別風送り方向の上手側に搬送されながら処理胴受網３０との相互作用で脱穀処理されて再び下方の揺動棚９上に落下して選別され、一方、扱室２内の脱穀物で揺動棚９上に落下せず処理室６内にも取り込まれなかった残りの脱穀物が扱室２の終端部まで搬送されて排塵処理室８内に取り込まれ選別風送り方向下手側に搬送されながら排塵処理胴７と排塵処理胴受網３１の相互作用でさらに脱穀されるとともにほぐされて中に混在していた穀粒が下方の揺動棚９上に落下し、該揺動棚９上に落下しなかった脱穀物が排塵処理室８の終端部まで搬送されて前記拡散手段１３によって排塵通路１４を経て機外へ直接放出されるように構成すると共に、前記排塵処理室８の終端部に、排塵通路１４方向への排塵物の排出を行う状態と排塵通路１４方向への排塵物の排出を停止する状態とに切り換える切換プレ−ト３４を設け、前記排塵処理胴７に作用する負荷が大きくなって該排塵処理胴７に掛かる駆動トルク値が上昇した場合に、前記切換プレ−ト３４を、排塵処理室８内の排塵物を排塵通路１４方向に排出させる状態に切り換えて、排塵処理室８内終端部の排塵物を直接機外へ排出するように構成したことを特徴とする脱穀装置とし、第２の手段として、脱穀装置１内に設けられた扱室２内には、フィードチェン３によって送られてきた穀稈を脱穀処理する扱胴４を軸架し、扱室２の一側には脱穀物を処理する処理胴５を内部に軸架する処理室６を設けると共に、該処理室６の後方には、前記処理胴５と同軸で一体的に回転して、扱室２の後部から送られてくる排塵物を処理する排塵処理胴７の架設されている排塵処理室８を設け、前記扱室２と処理室６と排塵処理室８の下方には落下してくる脱穀物を受けて選別する揺動棚９を設け、該揺動棚９の下方位置で選別風送り方向の始端側には唐箕１０を設け、選別風送り方向下手側に一番ラセン１１を、該一番ラセン１１の選別風送り方向下手側に二番ラセン１２をそれぞれ設け、前記排塵処理胴７の終端部には排塵物を拡散する拡散手段１３を設け、該拡散手段１３にて拡散された排塵物を直接機外に案内して放出する排塵通路１４を排塵処理室８の終端部に連通して脱穀装置１とグレンタンク２６の間の空間部を通過して後方の機外へ延出して設けて、二番ラセン１２内に取り込まれた二番物が二番揚穀筒３３にて処理室６の選別風送り方向下手側に還元されて扱室２からの脱穀物と合流し選別風送り方向の上手側に搬送されながら処理胴受網３０との相互作用で脱穀処理されて再び下方の揺動棚９上に落下して選別され、一方、扱室２内の脱穀物で揺動棚９上に落下せず処理室６内にも取り込まれなかった残りの脱穀物が扱室２の終端部まで搬送されて排塵処理室８内に取り込まれ選別風送り方向下手側に搬送されながら排塵処理胴７と排塵処理胴受網３１の相互作用でさらに脱穀されるとともにほぐされて中に混在していた穀粒が下方の揺動棚９上に落下し、該揺動棚９上に落下しなかった脱穀物が排塵処理室８の終端部まで搬送されて前記拡散手段１３によって排塵通路１４を経て機外へ直接放出されるように構成すると共に、前記排塵処理室８の終端部に、排塵通路１４方向への排塵物の排出を行う状態と排塵通路１４方向への排塵物の排出を停止する状態とに切り換える切換プレ−ト３４を設け、フィ−ドチェン３によって投入される穀稈の量が多くなった場合に、前記切換プレ−ト３４を、排塵処理室８内の排塵物を排塵通路１４方向に排出させる状態に切り換えて排塵処理室８内終端部の排塵物を直接機外へ排出するように構成したことを特徴とする脱穀装置とした。
【０００７】
上記構成のコンバインやハーベスタ等の脱穀装置で、扱室２の終端部近傍から排塵処理室８内に取り込まれた脱穀物は、該排塵処理室８内でさらに脱穀処理されて、その一部の脱穀物は下方の揺動棚９上に落下するが、落下しなかった排塵物は、さらに排塵処理室８の終端部まで搬送されてくる。この排塵物が機外へと排出されるにあたり、排塵処理胴７の終端部には拡散手段１３が設けてあるので、排塵物にはこの拡散手段１３によって排塵処理胴７の軸芯方向に対して直交する方向に拡散する遠心力を与えられ、円周方向へと移動する作用を与えられ、排塵通路１４を経て機外へと直接放出される。
【０００８】
また、基本的に、排塵処理胴７に大きな負荷が作用している時は、排塵物が多く発生していることを意味し、従って、フィ−ドチェン３によって投入される穀稈の量が多いということであるので、揺動棚９上にも多くの脱穀物が存在することが推測できるが、このような時に、排塵物を揺動棚９上に落下させると選別が悪くなるので、排塵処理室８内終端部の排塵物は直接機外へと排出するようにする。
【０００９】
【発明の効果】
請求項１記載の発明によると、排塵処理胴７に作用する負荷が大きくなって該排塵処理胴７に掛かる駆動トルク値が上昇した場合に、切換プレ−ト３４が排塵処理室８内の排塵物を排塵通路１４方向に排出させる状態に切り換わるため、排塵処理室８の終端部まで搬送されてきた排塵物は、揺動棚９上に落ちることなく、直接排塵通路１４から機外へと排出され、揺動棚９の選別能力が向上し揺動棚９の破損を防止できる。
【００１０】
また、請求項２記載の発明によると、フィ−ドチェン３によって投入される穀稈の量が多くなった場合に、前記切換プレ−ト３４が排塵処理室８内の排塵物を排塵通路１４方向に排出させる状態に切り換わるため、排塵処理室８の終端部まで搬送されてきた排塵物は、揺動棚９上に落ちることなく、直接排塵通路１４から機外へと排出され、揺動棚９の選別能力が向上し揺動棚９の破損を防止できる。
【００１１】
【発明の実施の形態】
図１には、本発明の実施例を具備したコンバインが示されている。
走行装置１６を有する機体フレーム１７の前方には、刈取装置１８と供給搬送装置１９が設けられている。刈取装置１８には、植立穀稈を分草する分草具２０と、植立穀稈を引き起こす引起しケース２１と、植立穀稈を刈り取る刈刃２２と、該刈刃２２にて刈り取られた穀稈を挟持して後方に搬送する株元搬送装置２３から構成されている。この株元搬送装置２３の後方には、該株元搬送装置２３から搬送されてくる穀稈を引き継いで搬送する供給搬送装置１９が設けられている。
【００１２】
前記刈取装置１８は、走行伝動装置２４の上方の支点を中心にして上下動する刈取装置支持フレーム２５にて、その略左右中間部で支持されているので、刈取装置１８は刈取装置支持フレーム２５と共に上下動する構成である。
【００１３】
機体フレーム１７の上方には、前記供給搬送装置１９から搬送されてくる穀稈を引き継いで搬送するフィードチェン３を有する脱穀装置１と、該脱穀装置１で脱穀選別された穀粒を一時貯溜するグレンタンク２６が載置されている。脱穀装置１の後方には、フィードチェン３から搬送されてくる排稈を引き継いで搬送する排稈チェン２７と、該排稈チェン２７の下方には排稈を切断するカッター２８を設けている。また、カッター２８以外の、例えば、排稈を結束するノッター等の他の作業機を搭載してもよい。
【００１４】
図２と図３には、それぞれ脱穀装置１の側面図と平面図が示されている。
脱穀装置１内には、扱胴４を扱胴軸４ａで軸架した扱室２と、該扱室２の一側には脱穀物を処理する処理胴５を処理胴軸５ａで軸架した処理室６を設けていて、さらに、前記処理室６の後方で、且つ、処理胴軸５ａと同じ軸に排塵処理胴７を軸架している排塵処理室８を設けている。扱胴４と処理胴５と排塵処理胴７の下方には、それぞれ扱胴受網２９と処理胴受網３０と排塵処理胴受網３１が設置されている。
【００１５】
前記扱室２と処理室６と排塵処理室８の下方には、落下してくる脱穀物を受けて選別する揺動棚９が設置されていて、該揺動棚９の下方には、選別風送り方向始端側に唐箕１０を設け、該唐箕１０から送風される選別風の送り方向下手側には一番ラセン１１を設け、該一番ラセン１１の選別風送り方向下手側には二番ラセン１２を設けている。
【００１６】
揺動棚９の構成について説明する。揺動棚９は、選別送り方向の始端側から順番に、落下した脱穀物を後方に移送する移送棚９ａ、脱穀物を選別するチャフシーブ９ｂ、排塵を機外に移送して放出するストローラック９ｃから構成されている。
【００１７】
横断流ファン１５は、選別室３２内の軽い塵を機外に排出するためのもので、ストローラック９ｃの上方に構成している。このような脱穀装置１において、前記排塵処理胴７の終端部には、排塵物に遠心力を与えて拡散する拡散手段１３を設け、且つ、該拡散手段１３にて円周方向に移動してきた排塵物を直接機外へと案内する排塵通路１４を設けている。本実施例において拡散手段１３は、プレートを排塵処理胴の長手方向に固着している構成であるが、排塵物に遠心力を与えて円周方向に移動させることができるものであれば、どのような構成のものでもよい。又、排塵通路１４は、脱穀装置１とグレンタンク２６の間の空間部を通過して、後方の機外へと延出している。
【００１８】
前述のごとく構成された脱穀装置１を搭載したコンバインにおいて、エンジン（図示せず）からの動力を走行伝動装置２４に入力して、任意の速度に変速して走行装置１６を駆動する。すると、コンバインは前進を開始する。刈取脱穀作業を行なうには、さらに、刈取装置１８，供給搬送装置１９及び脱穀装置１に、エンジンからの動力を伝達駆動して作業を行なう。このような状態でコンバインが前進すると、植立穀稈は分草具２０により分草されて、引起しケース２１にて引き起こされる。その後、刈刃２２にて刈り取られ、刈り取られた穀稈は、株元搬送装置２３により後方の供給搬送装置１９の始端部に向かって搬送される。
【００１９】
株元搬送装置２３の終端部まで搬送された穀稈は、後方の供給搬送装置１９の始端部に引き継がれる。その後、供給搬送装置１９の終端部まで搬送された穀稈は、脱穀装置１のフィードチェン３の始端部に引き継がれると共に、該フィードチェン３に引き継がれた穀稈は、後方に搬送されながら、扱胴４と扱胴受網２９により脱穀される。脱穀された脱穀物の一部は揺動棚９上に落下して、該揺動棚９の揺動作用と唐箕１０からの風選作用により選別され、一番ラセン１１内へと取り込まれていく。該一番ラセンに取り込まれた穀粒は、グレンタンク３０に一時貯溜されて、脱穀後の排稈は、フィードチェン３の終端部から、排稈チェン２７の始端部に引き継がれて搬送され、その後、カッター１６に送られて切断され、下方の圃場面に放出される。
【００２０】
扱室２内の残りの脱穀物は、後方へと搬送されていくが、その途中において一部の脱穀物は処理室６内に取り込まれていく。該処理室６内に取り込まれた脱穀物は、選別風送り方向上手側に搬送されながら、処理胴５と処理胴受網３０の作用で脱穀されて、下方の揺動棚９上に落下していく。扱胴４と処理胴５と排塵処理胴７は共に、図４と図５の正面視（選別風上手側から下手側を見る）において、時計回りで回転する構成であるので、従って、処理胴５の処理歯５ｂの向きは、脱穀物を選別風送り方向の上手側方向に送るような向きに固着しておく必要がある。また、排塵処理胴７の排塵処理歯７ａは、脱穀物を選別風送り方向の下手側方向に送るような向きに固着しておく必要がある。図４は脱穀装置１のＳ１ーＳ１断面であり、図５は脱穀装置１のＳ２ーＳ２断面を示している。
【００２１】
前述のように、扱室２内の脱穀物で、揺動棚９上に落下せず、処理室６内にも取り込まれなかった残りの脱穀物は、扱室２の終端部まで搬送されて、排塵処理室８内に取り込まれ、次いで、選別風送り方向下手側に搬送されながら、排塵処理胴７と排塵処理胴受網３１の相互作用で、さらに脱穀されるとともに、脱穀物はほぐされて中に混在している穀粒（いわゆるササリ粒）が取り出されて、下方の揺動棚９上に落下していく。該揺動棚９上に落下しなかった脱穀物は、排塵処理室８の終端部まで搬送されていく。
【００２２】
揺動棚９の揺動作用と唐箕１０からの選別風の作用にもかかわらず、一番ラセン１１内に取り込まれなかった残りの穀粒は、他の排塵物と共にさらに後方に送られ、二番ラセン１２内へと取り込まれていく。該二番ラセン１２内に取り込まれた二番物は、二番揚穀筒３３にて前記処理室６の選別風送り方向下手側に還元されて、扱室２からの脱穀物と合流し、その後、選別風送り方向の上手側に搬送されながら、処理胴受網３０との相互作用で脱穀処理されて、再び下方の揺動棚９上に落下して選別される。
【００２３】
このような一連の作業を行う脱穀装置１を搭載したコンバインにおいて、前述したように、排塵処理胴７の終端部に、拡散手段１３を設け、且つ、該拡散手段１３にて遠心力を与えられて円周方向への移動作用をする排塵物を直接機外へと案内する排塵通路１４を設ける構成とする。図６は、脱穀装置１のＳ３ーＳ３断面であり、排塵処理室８の終端部の断面を示している。
【００２４】
従来は、排塵処理室８の終端部まで搬送されてきた排塵物は、揺動棚９上に落下し、一部は横断流ファン１５による吸引力により吸引されて機外へと排出されていた。しかしながら、排塵処理室８の終端部まで搬送されてきた排塵物は、既に前述のササリ粒も取り出されていて、その殆どは排塵物である。このようなものを揺動棚９上に一時に多量に落下させると、該揺動棚９による揺動作用と、唐箕１０からの選別風の作用にもかかわらず、選別能力は低下し、その結果二番ラセン１２へと還元される二番物の選別が非常に悪くなると共に、特に、コンバインを高速で走行させてフィードチェン３で搬送されてくる穀稈の量が多量になると、揺動棚９上を移動する脱穀物が詰まったり、最悪の場合揺動棚９が破損したりすることになる。
【００２５】
そこで、本発明の構成により、排塵処理室８の終端部まで搬送されてきた排塵物は、揺動棚９上に落ちることなく、直接排塵通路１４から機外へと排出されるので、揺動棚９の選別能力は向上し揺動棚９の破損を防止できる。
【００２６】
次に、図７（ａ），（ｂ）について説明する。
これは、図６において説明した排塵処理室８の終端部構成の別の実施例である。一定の条件のもとに排塵通路１４方向への排塵物の排出を行ったり、停止したりする切換プレート３４を設ける構成とする。該切換プレート３４は、電気的なモータ３５で動く構成であるが、油圧等の他の方法でもよい。この切換プレート３４の切り換えの条件は、排塵処理胴７に掛かっているトルク値の上昇に関連して、排塵処理室８内の排塵物が排塵通路１４方向に排出するように切り換えるようにする。（トルクセンサは図示せず）
基本的には、排塵処理胴７に大きな負荷が作用している時は、排塵物が多く発生していることを意味し、従って、フィードチェン３によって投入される穀稈の量が多いということであるので、揺動棚９上にも多くの脱穀物が存在することが推測できる。このような時に、排塵物を揺動棚９上に落下させると、前述のように選別が悪くなるので、排塵処理室８内終端部の排塵物は直接機外へと排出するようにする。
【００２７】
排塵処理胴７に掛かっているトルク値検出の別実施例として、揺動棚９上に存在する脱穀物の量を直接検出してもよい。
次に、図８と図９について説明する。
【００２８】
排塵処理胴７の終端部に、排塵物を強制的に後方へと送り作用をするファン３６を設けると共に、該ファン３６から送られてくる排塵物を専用に受けて機外へと排出する大径横断流ファン１５ａを設ける構成とする。しかも、排塵処理室８の終端から大径横断流ファン１５ａの吸引口までにおいて、排塵物が下方に落下しないように、案内ガイド３７を設けているので、排塵物は効率よく大径横断流ファン１５ａに案内される。
【００２９】
案内ガイド３７について説明する。
排塵処理胴７の下方に設けてある排塵処理胴受網３１の終端部に案内ガイド３７をボルト等で固定する。しかも、排塵処理室８内終端部の排塵物が選別室３２内へ流れ込まないように、円周方向にわたって囲んでいる構成である。
【００３０】
これにより、排塵処理室８内終端部の排塵物は揺動棚９上に落下することなく、従って、選別能力が下がることがなくなる。
次に、図１０と図１１について説明する。
【００３１】
コンバインにおいては、脱穀装置１で脱穀した穀粒はグレンタンク２６へと一時貯留し、満杯となったら排出オーガ３８の排出口３８ａからトラック等の荷台へ排出する。前記排出オーガ３８は、縦オーガ３９と横オーガ４０から構成されていて、縦オーガ３９は横オーガ４０と共にモータ４１により歯車４２，４３を介して旋回し、横オーガ４０は油圧シリンダ４４により上昇下降する構成である。また、このような排出オーガ３８の一連の動作を行うオーガ操作レバー４５は操作席４６に設けられている。オーガ操作レバー４５は図１１に示すように、一本のレバーにて上昇下降と左右の旋回ができるようになっている。さらに、該オーガ操作レバー４５の近傍には、排出オーガ３８の排出口３８ａの位置を自動であらかじめ設定している位置まで移動する自動張出しスイッチ４７と、グレンタンク２６内の穀粒の排出を介しする排出スイッチ４９と、穀粒排出後に排出オー
ガ３８を元の位置のオーガ受け５０まで自動で収納する自動収納スイッチ４８が設けられている。
【００３２】
この電気的構成が図１２に示してある。
制御手段１００（以下、ＣＰＵという）の入力側には、前述のオーガ操作レバー４５の移動位置を検出するポジションセンサ５１が接続していて、該オーガ操作レバー４５の移動している位置をＣＰＵ１００に送信する。さらに入力側には、自動張出しスイッチ４７と、排出スイッチ４９と、自動収納スイッチ４８が接続されている。ＣＰＵ１００の出力側には、前述の油圧シリンダ４４と、モータ４１と、穀粒排出モータ５２が接続されている。
【００３３】
該穀粒排出モータ５２の構成について説明する。エンジン（図示せず）からの一部の動力は、図１３のように軸５３からベルト５４を介して軸５５へと入力される。該軸５５は、グレンタンク２６内の下部ラセン５６と直結していて、軸５５が回転すると、下部ラセン５６により穀粒が縦オーガ３９へと送られ、横オーガ４０を通過して排出口３８ａから排出される。図１４は図１３のＡ方向から見ている図であり、ベルト５４のテンション５４ａを入り切りする穀粒排出モータ５２が示してある。前記排出スイッチ４９が入り状態となると、穀粒排出モータ５２が回転してテンション５４ａがベルト５４を張る方向に回転して該ベルト５４を張り、これにより軸５５が回転する構成である。
【００３４】
前述のような構成を備えたコンバインにおいて、排出オーガ３８の排出口３８ａを任意の位置に移動し、その後、排出スイッチ４９を入り状態としてグレンタンク２６内の穀粒を排出している際に、不用意にオーガ排出レバー４５や自動収納スイッチ４８を操作してしまうと、排出口３８ａの位置がトラック等の荷台からずれて、排出中の穀粒が飛散してしまう。そこで、縦オーガ３９と横オーガ４０の回動支点の基部にそれぞれポジションセンサ（図示せず）を設置し、該ポジションセンサからの検出値によって排出口３８ａの位置がずれたことをＣＰＵ１００が判定すると、前記穀粒排出モータ５２の駆動を停止する信号を送信して、テンション５４ａを切り状態として、穀粒の排出を停止するようにする。これにより、不用意に排出口３８ａの位置が動いても、穀粒の飛散を防止できる。なお、コンバインに限らず、穀粒をグレンタンク内に専用に貯蔵して走行する運搬車等にも利用できる。

BACKGROUND OF THE INVENTION
The present invention relates to a threshing apparatus such as a combine or a harvester.
[0002]
[Prior art]
Conventional threshing devices such as combine harvesters and harvesters are provided with a dust disposal chamber on one side of the handling chamber to process the dust that is sent from the chamber, and the dust discharged from the end of the chamber is shaken. It is configured to fall on a moving shelf or to be sucked by a cross flow fan and released to the outside of the machine.
[0003]
[Problems to be solved by the invention]
Threshing devices such as the above-mentioned combine and harvester, in particular, naturally increase the amount of dust that is sent from the handling room to the dusting room when the amount of cereals thrown into the threshing device increases. Since the amount of dust that falls on the moving shelf increases, the sorting capacity on the swing shelf decreases, and in the worst case, the sorting ability of the swing shelf is exceeded and the swing shelf is damaged. There were such drawbacks.
[0004]
The present invention is intended to solve such problems.
[0005]

Any configuration may be used. The dust passage 14 extends through the space between the threshing apparatus 1 and the grain tank 26 and extends to the outside of the rear machine.
[0018]
In a combine equipped with the threshing device 1 configured as described above, power from an engine (not shown) is input to the traveling transmission device 24, and the traveling device 16 is driven by shifting to an arbitrary speed. Then, the combine begins to move forward. In order to perform the reaping and threshing operation, the reaping device 18, the feeding and conveying device 19, and the threshing device 1 are further driven by transmitting power from the engine. When the combine moves forward in such a state, the planted culm is weeded by the weeding tool 20 and is raised and caused in the case 21. Thereafter, the cereals harvested by the cutting blade 22 are transported toward the starting end portion of the rear supply transport device 19 by the stock transport device 23.
[0019]
The cereals that have been transported to the terminal end of the stock transporting device 23 are taken over by the starting end of the rear supply transporting device 19. Thereafter, the cereals that have been transported to the terminal end of the supply and transport device 19 are handed over to the starting end of the feed chain 3 of the threshing device 1, and the cereals that have been handed over to the feed chain 3 are being transported backward, Threshing is performed by the handling cylinder 4 and the handling cylinder receiving net 29. A part of the threshed threshing falls on the swing shelf 9 and is sorted by the swinging action of the swing shelf 9 and the wind-selecting action from the red pepper 10 and taken into the spiral 11 most. Go. The grain taken into the first helix is temporarily stored in the Glen tank 30, and the waste after threshing is transferred from the terminal end of the feed chain 3 to the start end of the waste chain 27 and conveyed. Then, it is sent to the cutter 16 to be cut and released to the lower farm scene.
[0020]
The remaining threshing in the handling chamber 2 is conveyed rearward, and a part of the threshing is taken into the processing chamber 6 in the middle of the process. The threshing taken into the processing chamber 6 is threshed by the action of the processing cylinder 5 and the processing cylinder receiving net 30 while being transported to the upper side in the sorting wind feed direction, and falls on the lower swing shelf 9. To go. The handling cylinder 4, the processing cylinder 5 and the dust removal processing cylinder 7 are all configured to rotate clockwise in the front view of FIG. 4 and FIG. 5 (viewed from the selected wind upper side to the lower side). It is necessary to fix the direction of the processing teeth 5b of the trunk 5 in such a direction that the threshing is sent in the upper direction of the sorting wind feed direction. Further, the dust removal processing teeth 7a of the dust removal processing cylinder 7 need to be fixed in such a direction as to send the cereals in the lower direction of the sorting wind feed direction. FIG. 4 is an S1-S1 cross section of the threshing apparatus 1, and FIG. 5 shows an S2-S2 cross section of the threshing apparatus 1.
[0021]
As described above, the remaining cereal that has not fallen on the swing shelf 9 and is not taken into the processing chamber 6 due to cerealing in the processing chamber 2 is transported to the end of the processing chamber 2. Then, it is taken into the dust removal processing chamber 8 and then further threshed by the interaction of the dust removal treatment cylinder 7 and the dust collection treatment cylinder receiving net 31 while being transported to the lower side in the sorting air feed direction. Grains that are loosened and mixed in (so-called scorpion grains) are taken out and fall onto the swing rack 9 below. The shed grains that have not fallen on the swing shelf 9 are transported to the end of the dust disposal chamber 8.
[0022]
Despite the swinging action of the swinging shelf 9 and the action of the sorting wind from the red pepper 10, the remaining grains that are not taken into the spiral 11 are sent further back together with other dusts. It is taken into the second spiral 12. The second product taken into the second helix 12 is reduced to the lower side in the sorting air feed direction of the processing chamber 6 in the second lifting cylinder 33 and merged with the cereal from the handling chamber 2, Thereafter, the threshing process is performed by interaction with the processing cylinder receiving net 30 while being transported to the upper side of the sorting wind feed direction, and again falls on the lower swing shelf 9 and sorted.
[0023]
In the combine equipped with the threshing device 1 for performing such a series of operations, as described above, the diffusion means 13 is provided at the end portion of the dust removal treatment cylinder 7, and centrifugal force is applied by the diffusion means 13. In this configuration, a dust passage 14 is provided for guiding the dust that is moved in the circumferential direction directly to the outside of the machine. FIG. 6 is an S3-S3 cross section of the threshing apparatus 1, and shows a cross section of the end portion of the dust removal processing chamber 8.
[0024]
Conventionally, the dust that has been transported to the end of the dust disposal chamber 8 falls on the swing shelf 9 and is partially sucked by the suction force of the cross flow fan 15 and discharged outside the apparatus. It was. However, the dust particles that have been transported to the end of the dust processing chamber 8 have already been taken out of the above-mentioned scorpion grains, and most of them are dust particles. When a large amount of such a thing is dropped on the swing shelf 9 at a time, the sorting ability is lowered despite the swinging action by the swing shelf 9 and the action of the sorting wind from the tang 10. As a result, the selection of the second product to be reduced to the second spiral 12 becomes very poor, and particularly when the amount of cereals conveyed by the feed chain 3 is increased by running the combine at high speed, The threshing that moves on the shelf 9 is clogged, or in the worst case, the swing shelf 9 is damaged.
[0025]
Therefore, according to the configuration of the present invention, the dust that has been conveyed to the end of the dust treatment chamber 8 is directly discharged from the dust passage 14 to the outside without falling on the swing shelf 9. The sorting ability of the swing shelf 9 is improved, and the swing shelf 9 can be prevented from being damaged.
[0026]
Next, FIGS. 7A and 7B will be described.
This is another embodiment of the end portion configuration of the dust removal processing chamber 8 described in FIG. A switching plate 34 is provided that discharges or stops the dust in the direction of the dust passage 14 under certain conditions. The switching plate 34 is configured to move by an electric motor 35, but may be other methods such as hydraulic pressure. The switching condition of the switching plate 34 is switched so that the dust in the dust processing chamber 8 is discharged in the direction of the dust passage 14 in relation to the increase in the torque value applied to the dust processing cylinder 7. Like that. (Torque sensor not shown)
Basically, when a large load is acting on the dust processing cylinder 7, it means that a large amount of dust is generated. Therefore, the amount of cereals thrown in by the feed chain 3 is large. Therefore, it can be estimated that a large amount of threshing is also present on the swing shelf 9. In such a case, if the dust is dropped onto the swing shelf 9, the sorting becomes worse as described above, so that the dust at the end of the dust treatment chamber 8 is directly discharged outside the machine. To.
[0027]
As another example of detecting the torque value applied to the dust removal processing cylinder 7, the amount of shed grains present on the swing shelf 9 may be directly detected.
Next, FIGS. 8 and 9 will be described.
[0028]
A fan 36 is provided at the end of the dust exhausting cylinder 7 for forcibly sending the dust to the rear, and the dust exhaust sent from the fan 36 is exclusively received and taken out of the machine. A large-diameter cross flow fan 15a for discharging is provided. Moreover, since the guide guide 37 is provided from the end of the dust disposal chamber 8 to the suction port of the large-diameter cross-flow fan 15a so that the dust does not fall downward, the dust is efficiently large-diameter. It is guided to the cross flow fan 15a.
[0029]
The guide guide 37 will be described.
A guide guide 37 is fixed to the end portion of the dust collection cylinder receiving net 31 provided below the dust collection cylinder 7 with a bolt or the like. And it is the structure enclosed over the circumferential direction so that the dust discharge material of the terminal part in the dust removal processing chamber 8 may not flow into the sorting chamber 32.
[0030]
As a result, the dust discharged from the end portion in the dust processing chamber 8 does not fall on the swing shelf 9, and therefore the sorting ability does not decrease.
Next, FIGS. 10 and 11 will be described.
[0031]
In the combine, the grain threshed by the threshing apparatus 1 is temporarily stored in the glen tank 26, and when full, the grain is discharged from the discharge port 38a of the discharge auger 38 to a loading platform such as a truck. The discharge auger 38 is composed of a vertical auger 39 and a horizontal auger 40. The vertical auger 39 is rotated together with the horizontal auger 40 by a motor 41 via gears 42 and 43, and the horizontal auger 40 is raised and lowered by a hydraulic cylinder 44. It is the structure to do. An auger operation lever 45 for performing a series of operations of the discharge auger 38 is provided in the operation seat 46. As shown in FIG. 11, the auger operation lever 45 can be moved up and down and turned left and right with a single lever. Further, in the vicinity of the auger operating lever 45, an automatic overhanging switch 47 that automatically moves the position of the discharge port 38a of the discharge auger 38 to a preset position and the discharge of the grains in the grain tank 26 are provided. And an automatic storage switch 48 for automatically storing the discharge auger 38 up to the auger receiver 50 at the original position after the grain is discharged.
[0032]
This electrical configuration is shown in FIG.
A position sensor 51 for detecting the moving position of the auger operating lever 45 is connected to the input side of the control means 100 (hereinafter referred to as CPU), and the moving position of the auger operating lever 45 is connected to the CPU 100. Send. Further, an automatic extension switch 47, a discharge switch 49, and an automatic storage switch 48 are connected to the input side. The hydraulic cylinder 44, the motor 41, and the grain discharging motor 52 are connected to the output side of the CPU 100.
[0033]
The configuration of the grain discharge motor 52 will be described. A part of the power from the engine (not shown) is input from the shaft 53 to the shaft 55 via the belt 54 as shown in FIG. The shaft 55 is directly connected to the lower spiral 56 in the grain tank 26, and when the shaft 55 rotates, the grain is sent to the vertical auger 39 by the lower spiral 56, passes through the horizontal auger 40 and passes through the discharge port 38a. Discharged from. FIG. 14 is a view as seen from the direction A of FIG. 13, and shows a grain discharging motor 52 for turning on and off the tension 54 a of the belt 54. When the discharge switch 49 is turned on, the grain discharge motor 52 rotates and the tension 54a rotates in the direction in which the belt 54 is tensioned to tension the belt 54, whereby the shaft 55 rotates.
[0034]
In the combine having the above-described configuration, when the discharge port 38a of the discharge auger 38 is moved to an arbitrary position and then the grain in the Glen tank 26 is discharged with the discharge switch 49 turned on, If the auger discharge lever 45 or the automatic storage switch 48 is inadvertently operated, the position of the discharge port 38a is deviated from the loading platform such as a truck, and the grains being discharged are scattered. Therefore, if a position sensor (not shown) is installed at the base of the pivotal fulcrum of the vertical auger 39 and the horizontal auger 40, and the CPU 100 determines that the position of the discharge port 38a is shifted by the detection value from the position sensor. Then, a signal for stopping the drive of the grain discharge motor 52 is transmitted to turn off the tension 54a to stop the discharge of the grain. Thereby, even if the position of the discharge port 38a moves carelessly, scattering of grains can be prevented. In addition, it can utilize not only for a combine but also for a transport vehicle that stores and travels grains in a Glen tank.
