【発明の属する技術分野】
刈取部で刈取った稲、麦、豆類など穀物をフィーダハウスを介し脱穀部に全量投入して脱穀処理する普通形コンバインに関する。
【０００２】
【発明が解決しようとする課題】
従来、脱穀部より右外側に運転操作部や穀物タンクやエンジンルームなどが並置する状態に設けられているため、各部の構成部材も多く部品点数が増加したり重量が増大して機体が複雑且つ大型化するという不都合があった。またこのため脱穀部の一部を開放してこの内部点検を行う内部点検作業なども容易には行えず極めて作業性の悪いものであった。
【０００４】
【課題を解決するための手段】
したがって本発明は、刈取穀稈を脱穀する複数の扱胴を脱穀部に備え、エンジンが車体後部に配設される普通形コンバインにおいて、機体の外枠を構成する左右の脱穀側板を支持部材として第一扱胴、第二扱胴およびエンジンルームが配設され、前記エンジンルール内に配設されるエンジンの出力軸が、前記左右いずれかの脱穀側板の外側で、前記第一扱胴を回転させる第一扱胴軸および前記第二扱胴を回転駆動させる第二扱胴軸と連結され、揺動選別盤の後方下端に配設された走行クローラの駆動部であるミッションケースの入力軸、および穀物タンクの底部排出オーガとが、それぞれ前記エンジンの出力軸と、前記脱穀側板の外側で連結され、かつ、前記左右いずれかの脱穀側板の他方側で、唐箕の唐箕駆動軸をカウンタ軸と連動連結させ唐箕と一番及び二番コンベアとが駆動するように配置することを特徴とするものであり、機体の左右バランスの安定と駆動系の簡素化を図るものである。
【０００５】
また、更に、走行クローラの駆動部であるミッションケースを揺動選別盤の後方下端に配設し、前記ミッションケースの入力軸と前記エンジンの出力軸とを、前記左右いずれかの脱穀側板の外側で連結し、揺動選別盤の影響を受けることのないミッションなど走行駆動部の左右方向に対する自由な設置を可能とさせると共に、揺動選別盤の後端上方を開放状態とさせた揺動選別盤の自由な設置を可能とさせるものである。また、揺動選別盤の後端上方にエンジンルームを配設して、揺動選別盤の外側位置でエンジンに走行駆動部を連動連結させて、揺動選別盤の後端上方の余剰スペースにエンジンルームをコンパクトに配設して、エンジンと走行駆動部との駆動系も簡潔にして伝達効率良好なものとさせるものである。
