【発明の属する技術分野】
この発明は、脱穀機に関するものである。
【０００２】
【従来の技術】
脱穀機を載置したコンバインによる立毛穀稈の収穫作業では、コンバインの走行車台の前部に設けた刈取機で立毛穀稈は刈取りされ、この刈取り穀稈は、この刈取機で後方上部へ移送され、走行車台の上側に載置した左・右側板と前後側板と中仕切板と後仕切板とで箱体に形成した脱穀機のフィードチエンと挟持杆とで引継ぎされ、これらフィードチエンと挟持杆とで挟持されて、脱穀機の上部に設けた脱穀室内を挟持移送中に脱穀され、脱穀済み穀粒及び一部の藁屑等は、この脱穀室から下部の選別室内に設けて、穀粒と藁屑等とに揺動選別する揺動選別装置へ供給される。
【０００３】
又、排塵物は、前記脱穀室からこの脱穀室の右横側で前部に設けた二番処理室と、後部に設けた排塵処理室とへ供給され、再度脱穀処理され、再脱穀処理された一部の穀粒及び藁屑等は、排塵処理室から選別室内に設けて揺動選別する揺動選別装置へ供給される。再脱穀処理された大半の藁屑は機外へ排出される。
【０００４】
更に未脱穀物である二番物は、前記脱穀機の右横側へ斜設した二番還元装置で揚送移送されて、排塵処理室の前側に設けた二番処理室内へ揚送還元され、この二番処理室内の二番胴の二番処理爪で再脱穀処理され、再脱穀処理された一部の穀粒及び藁屑は、この二番処理室から選別室内に設けて揺動選別する揺動選別装置へ供給される。この二番処理室を形成する一方側の右側板は、脱穀室の下側の選別室を形成する一方側の右側板より、所定距離右外側へ位置させている。
【０００５】
前記脱穀室、排塵処理室、及び二番処理室から選別室内の揺動選別装置へ供給された脱穀物及び再脱穀処理物は、揺動選別、及び風選別される。選別済み穀粒は穀粒貯留タンク内へ供給されて一時貯留される。又、選別された藁屑、塵埃、及び稈切等は機外へ排出される。
【０００６】
【発明が解決しようとする課題】
穀粒と、藁屑等に揺動選別する揺動選別装置を内装した選別室の一方側を形成する右側板の位置より、二番胴を内装して二番物を再脱穀処理する二番処理室を形成する右側板の位置を所定距離右外側へ位置させて設けたことにより、二番処理室内で再脱穀処理され、再脱穀処理された一部の穀粒、及び藁屑等は揺動選別装置の右側へ片寄って漏下供給される事が多くなり、このために、揺動選別性能が低下することが発生していた。又、右側板には、排塵処理室の下側に設けた排塵網、及び二番処理室の下側に設けた二番網等を着脱したり、掃除したりする排塵掃除口、及び二番掃除口を設けていないことにより、これらの各作業を容易に行うことができなかったが、この発明により、これらの問題点を解決しようとするものである。
【０００７】
【課題を解決するための手段】
このために、請求項１に記載の発明は、前側板（４ａ）及び後側板（４ｂ）と、左側板（５ａ）及び右側板（５ｂ）と、中仕切板（６ａ）及び後仕切板（６ｂ）によって箱体（３）を構成し、該箱体（３）内の上部に、穀稈を脱穀する脱穀室（７）を設け、該脱穀室（７）の右側後部に排塵物を処理する排塵処理室（８）を設け、脱穀室（７）の右側部に二番物を処理する二番処理室（９）を設け、前記脱穀室（７）下部に選別室（３０）を設け、該選別室（３０）内に穀粒と藁屑とを選別する揺動選別棚（３２ｄ）を設け、該揺動選別棚（３２ｄ）の前端部には移送棚（３２ａ）を設け、選別室（３０）の右側の側板となる前記右側板（５ｂ）を、前記二番処理室（９）内に設けた二番胴（９ａ）よりも右側へ偏倚させ、前記右側板（５ｂ）に、排塵掃除口（１０）と、前後方向において移送棚（３２ａ）の設置域の全域に亘る二番掃除口（１１）とを設け、該排塵掃除口（１０）から排塵処理室（８）下側の排塵網（８ｄ）を着脱自在に構成すると共に、二番掃除口（１１）から二番処理室（９）下側の二番網（９ｄ）を着脱して該二番掃除口（１１）から移送棚（３２ａ）上の穀粒や藁屑を除去できる構成とし、前記排塵網（８ｄ）を張設した排塵網枠（８ｅ）の後端部と前記後側板（４ｂ）との間に、排塵処理室（８）後端の排塵排出口（２９ａ）から排出される排塵物を外部へ排出案内する末広がりに形成したガイド板（４０）を設け、該ガイド板（４０）の後端部を揺動選別棚（３２ｄ）の後端部よりも所定距離前方に配置したことを特徴とする脱穀機としたものである。
【０００８】

そして、排塵網（８ｄ）を張設した排塵網枠（８ｅ）の後端部と後側板（４ｂ）との間に、排塵処理室（８）後端の排塵排出口（２９ａ）から排出される排塵物を排出案内する末広がりに形成したガイド板（４０）を設け、このガイド板（４０）の後端部を揺動選別棚（３２ｄ）の後端部よりも所定距離前方に配置することで、排塵排出口（２９ａ）から排出される藁屑を揺動選別棚（３２ｄ）上と外部とへ広範囲に分散して排出することができ、揺動選別性能の向上を図ることができる。
【００２０】
請求項２記載の発明によると、上記請求項１記載の発明の効果に加え、ガイド板（４０）の左側の部位を、揺動選別棚（３２ｄ）の後部上方に配置した排塵ファン（３８）のケーシング（３８ａ）の壁板に装着すると共に、このガイド板（４０）の右側の部位を右側板（５ｂ）の後部に設けたカッタ前壁板（４０ｂ）に装着することで、ガイド板（４０）を強固に取り付けることができる。
また、排塵処理室（８）の後端上半部分を形成する排塵後板（４１）に排塵胴（８ａ）の回転軸である排塵軸（４１ａ）を軸支し、排塵処理室（８）の後端下半部分にガイド板（４０）で排出案内される藁屑の排出通路を形成することで、藁屑の排出通路を大きく取ることができる。
