Is done.
As described above, threshing that has been threshed by the threshing machine, and removal of the small grains that are discharged to the discharged waste is as shown in Japanese Utility Model Laid-Open No. 5-41. That is, threshing is carried out by a barrel supported by a barrel shaft in the handling chamber, and the threshed waste is discharged from a waste outlet portion on the rear side of the handling chamber. The endless belt provided with protrusions at predetermined intervals spans the driving pulley provided at the transfer terminal end of the barrel shaft and the driven pulley provided on the handling port outside the handling chamber. By the rotational driving of the band, each protrusion is inserted into the evacuation, and the crushed grains are removed.

前記脱穀機３は、図１〜図３で示す如く扱室前・後板６ａ、６ｂ、及び扱室左・右板６ｆ、６ｈにより、略箱体に形成すると共に、この箱体内に形成する扱室６内には、扱室中前・中後板６ｃ、６ｄを設けた構成である。脱穀機３の上方左側部の扱口７ｄの前側には、刈取機４の根元・穂先移送装置１６ａ、１６ｂで上部へ移送された刈取り穀稈を引継ぎして、脱穀機３の扱室６内を挟持移送するフィードチェン５ａと、挟持杆５ｂとを設けた構成である。
前記脱穀機３の上部には、前後方向に扱室前・後板６ａ、６ｂ間に扱室６を設け、この扱室６には、扱胴軸７を回転自在に軸支して設けると共に、この扱胴軸７には、多種類で、多数本の扱歯７ｂを植設した扱胴７ａを軸支した構成である。又、扱胴７ａの扱歯７ｂの回転外周下部の扱室６には、脱穀処理物が漏下する扱室網７ｃを張設した構成である。
前記扱室６の移送終端部側には、扱室中前板６ｃと、扱室中後板６ｄとを所定間隔で設けて、扱室６内で脱穀されなかった未脱穀処理物（排塵物）を、詳細後述する排塵処理室１０内へ供給する脱穀供給口（供給口）６ｅを設けた構成である。
前記扱胴６の右側下方部には、図１、及び図２で示す如く脱穀供給口６ｅから未脱穀処理物（排塵物）の供給を設けて、再脱穀処理する排塵処理室１０を設けた構成である。この排塵処理室１０内には、排塵軸（排塵胴軸）１１を回転自在に軸支して設けると共に、この排塵軸１１には、螺旋プレート１１ｃと、複数個の排塵爪１１ｂと、排塵排出板１１ｄ等を装着した排塵胴１１ａを軸支した構成である。又、この排塵胴１１ａの排塵爪１１ｂ等の回転外周下部の排塵処理室１０には、再脱穀処理物が漏下する排塵網１１ｅを張設した構成である。
前記排塵処理室１０の排塵網１１ｅの移送終端部には、再脱穀処理されて、排塵網１１ｅから漏下しなかった、少量の穀粒と、排藁と、稈切等とが排出される排塵排出口１０ａを設けた構成である。

前記二番処理室２２の二番網２３ｄの移送終端部には、再脱穀処理されて、二番網２３ｄから漏下しなかった、少量の穀粒と、排藁と、稈切等とを排出する二番網２３ｄから漏下しなかった、少量の穀粒と、排藁と、稈切等とを排出する二番排出口２２ａを設けた構成である。
前記扱室６を形成する扱室後板６ｂと、未脱穀処理物〈排塵物〉を排塵処理室１０へ供給する脱穀供給口６ｅを形成する扱室中前・中後板６ｃ、６ｄの後側のこの扱室中後板６ｄとの間には、図１、及び図２で示す如くささり粒回収装置８のガイド部材９ａを設けた構成である。このガイド部材９ａは、脱穀済みの排藁を、扱室後板６ｂの排藁排出口６ｆから機外へ排出する際に、この排藁内へささっているささり粒を除去するためのもので、排藁へささり粒がささった状態のままで、この排藁排出口６ｆから機外の四番口へ持ち出されて排出される四番口の穀粒ロスを防止する構成である。
前記ガイド部材９ａは、図１、及び図２で示す如く扱室中後板６ｄと、扱室後板６ｂとの間で、脱穀する穀稈の穂先側で、更に扱胴７ａへ植設した扱歯７ｂの回転外周へ沿わせて、扱室６上部から排塵胴１１ａを軸支した排塵軸１７の中心（イ）位置より、所定位置下方部まで延長して設けた構成である。ガイド部材９ａと、各扱歯７ｂとの作用により、ささり粒の除去が良好なる構成である。
前記扱室中後板６ｄと、扱室後板６ｂとの間には、長い範囲でガイド部材９ａを設けたことにより、脱穀機３の機枠の剛性が向上する。又、脱穀供給口６ｅ部の強度アップを図ることができる。ささり粒回収部（ロ）で、扱室６内で発生した長藁等がガイド部材９ａの下端部に引掛り、揺動選別装置２５上を移送する選別物を停滞させたり、排塵処理室１０の処理室ケーシング１０ｂ上へささり落しにより、落下した穀粒、及び藁屑等の堆積を防止できる。排塵処理室１０の排塵網１１ｅから漏下した再脱穀処理物が、扱室６内で脱穀中の穀稈の穂先側部へ漏下することを防止できる。
前記扱室６へ内装軸支して、穀稈を脱穀する扱胴７ａへ植設する扱歯７ｂは、図３で示す如く植設した構成である。
前記扱胴７ａの移送始端部と、未脱穀処理物を排塵処理室１０内へ供給する脱穀供給口6ｅを形成する扱室中前板６ｃが位置する箇所との間へ植設する各扱歯７ｂは、後方へ向けて進み角（θ１）で植設した構成である。又、扱室中前板６ｃが位置する箇所と、扱胴７ａの移送終端部との間へ植設する扱歯７ｂは、前方へ向けて進み角（θ２）で植設した構成である。
前記扱胴７ａへ植設する各扱歯７ｂは、移送始端部側は、扱室６へ内装した扱胴７ａの移送始端部から、扱室中前板６ｃが位置する間は、後方へ向けて進み角（θ１）で植設した構成とすると共に、移送始端部側は、扱室中前板６ｃが位置する箇所と、扱胴７ａの移送始端部との間は、前方へ向けて進み角（θ２）で植設して設けた構成としたことにより、脱穀供給口６ｅ部で未脱穀処理物、及び脱穀中の穀稈へストップが掛った状態となり、排塵処理室１０内へ未脱穀処理物の取り込みが容易となり、このために、穀稈へささっているささり粒の取り込みも容易で良好になり、扱胴７ａの移送終端部側へ設けた、扱室後板６ｂの排藁排出口６ｆから機外へ排出される排藁へささっているささり粒が大巾に減少し、四番口へ排出される穀稈ロスを防止できる。
前記扱室６左側のフィードチェン５ａ側の脱穀する穀稈が供給されて通過する扱口７ｄ側の扱室６内には、図１〜図３で示す如く未脱穀処理物（排塵物）を、排塵処理室１０へ供給する脱穀供給口６ｅを形成する、後側の扱室中後板６ｄ部から脱穀済み排藁を、扱室６の扱室後板６ｂの排藁排出口６ｆから引継ぎして後方へ移送する排藁移送チェン１２へ向けて、上端部を上り傾斜状態で、更に後方側部を、扱胴軸７へ向けて、順次近接状態に株元支え上げガイド９ｂを設けた構成である。
前記扱室６の左側の扱口７ｄ側のこの扱室６内には、扱室中後板６ｄ部から、脱穀済みの排藁を受けて、移送する排藁移送チェン５ｃ側へ向けて、上端部が上り傾斜状態で、更に後方側を扱胴軸７へ向けて、順次接近状態に株元支え上げガイド９ｂを設けたことにより、この株元支え上げガイド９ｂにより、脱穀中で後方へ移送中の穀稈の株元側を後方へ移動されるにしたがって、扱胴７ａへ向け、穀稈を支え上げる状態にして、各扱歯７ｂが移送中の穀稈内へ深く入り込み、穀稈へささったささり粒の除去が良好になり、機外へ排出される四番口の穀粒ロスを防止している。又、排藁移送チェン５ｃへ排藁の引継ぎが良好になり、排藁の移送姿勢が安定し、引継ぎ時の排藁の詰りの防止ができる。
前記扱室６の下側には、図３で示す如く選別室２４を設け、この選別室２４内には、扱室６の扱室網７ｃから漏下する脱穀処理物、及び排塵処理室１０と、二番処理室２２の各網１１ｅと、２３ｄとから漏下する再脱穀処理物等の供給を受けて、揺動移送しながら、揺動選別する揺動選別装置２５を吊り下げ状態に設け、この揺動選別装置２５を揺動カム装置２５ａと、揺動ローラ装置２５ｂとにより、揺動移送しながら穀粒と、藁屑および塵埃等とに揺動選別する構成である。
前記揺動選別装置２５は、移送始端部側より、順次山形形状の移送棚２６ａと、複数個の前チャフシーブ２６ｂと、複数個の漏下量調節式の複数個の後チャフシーブ２６ｃと、複数個のストローラック２６ｄと、後チャフシーブ２６ｃの下側に、網部材等よりなるグレンシーブ２７ａと、ストローラック２６ｄの下側へ流下棚２７ｂ等とを設けた構成である。
