Description

【０００１】
【発明の属する技術分野】
本発明は扱室内で脱穀処理された穀物をこの下方の揺動選別盤で選別処理するようにしたコンバインの脱穀装置に関する。
【０００２】
【発明が解決しようとする課題】
従来の揺動選別盤にあっては、フィードパンは１枚板に形成され、この後端にチャフシーブが連設される構造となっている。しかし乍らこのような構造の場合、選別巾も狭く、藁屑など塵も塊り状となって分散し難く、特に５条刈り以上など大容量化すればする程この傾向が顕著となって選別精度を低下させるという問題があった。
【０００３】
【課題を解決するための手段】
然るに、本発明は、扱室（２２）に扱胴（６）を内設させ、脱穀排塵及び藁屑を機外後方に排出させる吸排塵ファン（３６）を扱胴（６）の後方に設け、扱胴（６）乃至吸排塵ファン（３６）の下方に揺動選別盤（２５）を設け、揺動選別盤（２５）下方で唐箕（３２）及び１番コンベア（３３）及び２番コンベア（３４）を前後に並設させ、唐箕（３２）の選別風を揺動選別盤（２５）に備えた下位のグレンシーブ（３０）と上位のチャフシーブ（２９）を介して上方の吸排塵ファン（３６）に向けて送給するコンバインの脱穀装置において、揺動選別盤（２５）前部に上下２段に前後フィードパン（２６，２７）を配設し、前フィードパン（２６）後側に篩線（２８）を取付け、また後フィードパン（２７）後端に前記チャフシーブ（２９）を連設させるもので、２つのフィードパン（２６，２７）により、選別面積を有効に拡大させることができると共に、扱胴（６）によって脱粒される大半の穀粒が前部から下方の前フィードパン（２６）に落下して均一分散されて後方移送でき、穀粒落下量が少なくなる中間下方で中間下方で篩線（２８）によって藁屑を分離し乍ら前フィードパン（２６）の穀粒を後フィードパン（２７）及びチャフシーブ前部に移動させることができ、チャフシーブ（２９）前部及びグレンシーブ（３０）を介して穀粒を速やかに漏下させて効率良く収集でき、揺動選別盤（２５）前部での穀粒選別効率の向上などを容易に図ることができるものである。
【０００４】
また、吸排塵ファンと篩線の間でチャフシーブ前後幅中間上方に扱胴後部を配設させることにより、扱胴の脱穀によって発生する藁屑の大半を篩線後方のチャフシーブ上面に落下させて速やかに機外に排出し得、フィードパンの穀粒に混在する藁屑の除去を篩線によって適正に行わせ得、選別損失の低減並びに選別効率の向上などを容易に図り得るものである。
【０００５】
また、篩線の前側下方から後側上方に送風するプレファンをフィードパン下方に設けることにより、側面視円形の外形状となる唐箕の斜前方上方にプレファンの取付スペースを容易に確保し得、揺動選別盤の前後幅内にコンパクトにプレファンを設置し得るものである。
【０００６】
また、扱胴前側面とフィードパン前端面とプレファン前側面を略面一に揃えることにより、脱穀部の前面を略垂直な平面状の壁面で形成し得、脱穀部の機筐構造の簡略化並びに不要空間の低減によるコンパクト化を容易に図り得るものである。
【０００７】
また、プレファンとグレンシーブの間でこれらの下方に唐箕を設けることにより、プレファン上方にフィードパンを配置させてフィードパンの前後幅を容易に確保し得、かつグレンシーブに唐箕を近接させて選別風を適正に送給し得、揺動選別盤の左右幅を拡大することなく選別能力の向上などを容易に図り得るものである。
【０００８】
また、１番コンベアの軸に対して高位置に設ける唐箕の軸よりもプレファンの軸をさらに高く位置させることにより、フィードパンとグレンシーブの配置に必要な高低差を利用して揺動選別盤の下面側にプレファンを近接させて配置し得、プレファン取付け構造のコンパクト化並びに簡略化を容易に行い得るものである。
【０００９】
【００１０】
また、フィードパン前端とグレンシーブ前端の間でこれらの下方にプレファンと唐箕を前後に近接させて設けることにより、フィードパン下面を送風ガイドとしてプレファンから篩線下側に送風し得、フィードパンの前後幅を確保して揺動選別盤の左右幅縮少またはフィードパン上での穀粒の左右方向分散を容易に図り得、しかも唐箕とグレンシーブの離反距離を適正に形成して唐箕の風選作用を適正に行わせ得るものである。

【００１３】
図５乃至図６に示す如く、前記篩い線（２８）は断面丸形の線体（２８ａ）を門形に折曲形成して、選別盤（２５）の揺動軸（２８）に固設する篩い線受け（３９）に、選別盤（２５）の全巾に亘って各線体（２８ａ）を略等間に櫛歯状に固定させるもので、選別盤（２５）の左右側壁（２５ａ）（２５ａ）間に回動自在に揺動軸（３８）を貫通支持させ、該揺動軸（３８）の篩い線受け（３９）に押え板（４０）及びボルト（４１）を介して篩い線（２８）の基端を挾着固定させている。

BACKGROUND OF THE INVENTION
The present invention relates to a combine threshing device in which grains threshed in a handling chamber are sorted by the lower swing sorter.
[0002]
[Problems to be solved by the invention]
In the conventional swing sorter, the feed pan is formed on a single plate, and a chaff sheave is connected to the rear end. However, in the case of such a structure, the sorting width is narrow and dust such as sawdust is lump-like and difficult to disperse. There was a problem of reducing the sorting accuracy.
[0003]
[Means for Solving the Problems]
However, in the present invention, the handling cylinder (6) is provided in the handling chamber (22), and the suction / discharge dust fan (36) for discharging threshing dust and sawdust to the rear rear side of the machine is located behind the handling cylinder (6). The swing sorter (25) is provided below the handling cylinder (6) to the suction / exhaust dust fan (36), and the Kara (32) and the first conveyor (33) and No. 2 are located below the swing sorter (25).
