Description

【０００１】
【発明の属する技術分野】
本発明は、荷受け部に荷受けされた搬送されてくる穀物を一時貯留する貯留部、この貯留部から供給される穀物を選別処理する選別部、選別処理された穀物を計量処理する計量部を上下方向に並べて備える荷受け処理部が設けられた穀物処理設備に関する。
【０００２】
【従来の技術】
上記構成の穀物処理設備において、従来では、例えば、穀物処理設備における建屋に設けられた複数階の床面（設置面）に夫々各別に設置させる構成のものがあった。つまり、最上階の床面に前記貯留部を設置し、その下の階の床面に前記選別部を設置し、更にその下の階の床面に前記計量部を設置するようにして、それらの各部同士を穀物流下用の案内経路等により連通させる構成である。
【０００３】
しかし、このような構成においては、前記各階における床面に対して、前記貯留部、前記選別部、前記計量部を夫々各別に設置する手間が掛かるとともに、それらの間に穀物搬送経路を別途、長尺のシュートパイプ等を用いて形成する手間も必要であり、設置施工の手間が多く掛かる不利な面があった。
【０００４】
そこで、上記従来構成における不具合を解消するために、次のような構成が考えられた。つまり、上下方向に並ぶ状態で備えられる前記貯留部、前記選別部、前記計量部の夫々を、大型の支持枠にて支持することで一体的な組物として構成して、１つの設置面に設置支持するような構成である。例えば、前記各部の全てを囲うように大型の支持枠を設置面に設置支持させる状態で設けて、この支持枠に対して、前記各部を夫々単独で組み付けるようにしたものがあった。
【０００５】
【発明が解決しようとする課題】
上記改良構成においては、上記従来構成のように建屋における複数階の床面に夫々各別に前記各部を設置する構成に比べると、例えば、前記各部に対する電源供給用の配線や排塵用の配管等を各階毎に別途施工する手間や、前記各部同士を長尺のシュートパイプ等を用いて穀物搬送経路を別途形成する等の煩わしい手間が少なくなり、その分、設備全体として設置施工の手間は少なくなるものの、次のような面で未だ改善の余地があった。
【０００６】
つまり、上記構成においては、上下方向に並ぶ貯留部、選別部、計量部の各部の全てを囲うような大型の支持枠を用意する必要があるが、このような支持枠は非常に大型の部材となり、運搬や設置のための設備が大掛かりになり、却って設置に手間がかかることになり、又、このような大型の部材に対して、前記各部を各別に組み付ける場合、支持枠の内部の狭い個所で行わねばならず、組み付け作業が行い難いものとなる不利があった。
【０００７】
本発明はかかる点に着目してなされたものであり、その目的は、合理的な構成によって設置作業を極力簡単に行うことが可能となる穀物処理設備を提供する点にある。
【０００８】
【課題を解決するための手段】
請求項１に記載の特徴構成によれば、前記荷受け処理部が、上下方向に並ぶ複数の構成体にて構成され、前記各構成体は、最下段側の構成体が設置面に荷重が支持される状態で設置され、下側の構成体が上側の構成体の荷重を支持するように、順次積み重ねるとともに互いに連結して一体的に組み付けられて構成されている。
【０００９】
つまり、前記各構成体のうち最下段側の構成体を設置面に荷重が支持される状態で設置した後に、その上に順次各構成体を積み重ねて載置し、それらの構成体同士を連結して一体的に組み付けて、設置作業が終了することになる。前記各構成体は上記したような改良構成における支持枠に比べて比較的小型の形状であり、このような小型の装置を順次積み重ねるとともに、それらを互いに連結するだけの作業で対応できるので、大型の部材がなく小型同士を積み重ねて連結するという極めて簡単な設置作業によって施工が行えることになる。しかも、前記各部間での穀物搬送経路として短いもので済ませることができ、長尺のシュートパイプ等を用いて穀物搬送経路を別途形成する等の煩わしい手間は不要である。
【００１０】
また、請求項１に記載の特徴構成によれば、前記選別部が、搬入された穀物の粗選別を行う粗選別部にて構成されている。
つまり、荷受け部に荷受けされて搬送されてくる穀物が、貯留部にて一時貯留され、この貯留部から供給される穀物が粗選別部にて粗選別が行われた後、計量部にて計量される。そして、その後、乾燥処理や貯蔵処理等の後工程に移送されていくことになる。従って、荷受け用の一連の処理が行われる装置部分が、上下方向に積み重ねられて一体的に組み付けられた構成となり、大型の部材がなく小型同士を積み重ねて連結するという極めて簡単な設置作業によって施工が行えることになる。
【００１１】
また、請求項１に記載の特徴構成によれば、下部側に位置する計量部の構成体は、フレーム材が格子状に組み立てられた枠組体にて荷重を支持するように構成されているので、充分な強度にて荷重を支持する構成でありながら、例えば、メンテナンス作業やその他の作業を行うために、設置面と同一面（設備の床面）を移動することになる作業者が、枠組体のフレーム材の間の隙間から広い範囲にわたり目視で確認でき、見通しがよく作業が行い易いものとなる利点がある。
また、請求項１に記載の特徴構成によれば、前記各構成体の夫々に、それらが組み付けられた状態で上下方向に連通して穀物搬送用通路を構成する通路形成用筒部が形成され、前記穀物搬送用通路に、前記計量部にて計量が終了した後の前記穀物を次工程の移送用位置まで上揚搬送する搬送コンベアが備えられるとともに、塵埃吸引排気用のダクトが設けられている。
この種の穀物処理設備では、前記計量処理が終了した後、例えば、乾燥工程や貯蔵工程等の次工程への移送用位置まで、搬送コンベアにて穀物を上揚搬送させる構成となっているが、上記したように、積み重ねられる各構成体の夫々に形成した筒部により穀物搬送用通路が形成される構成とし、この穀物搬送用通路に、搬送コンベアが備えるとともに、塵埃吸引排気用のダクトが設けられる構成とすることによって、各構成体とは別に搬送コンベアの通路部分や前記ダクトを構成する場合に比べて、部材の兼用化によって、構成の簡素化を図ることができる。
【００１２】
請求項２に記載の特徴構成によれば、前記荷受け処理部が、上下方向に並ぶ複数の構成体にて構成され、前記各構成体は、最下段側の構成体が設置面に荷重が支持される状態で設置され、下側の構成体が上側の構成体の荷重を支持するように、順次積み重ねるとともに互いに連結して一体的に組み付けられて構成されている。
つまり、前記各構成体のうち最下段側の構成体を設置面に荷重が支持される状態で設置した後に、その上に順次各構成体を積み重ねて載置し、それらの構成体同士を連結して一体的に組み付けて、設置作業が終了することになる。前記各構成体は上記したような改良構成における支持枠に比べて比較的小型の形状であり、このような小型の装置を順次積み重ねるとともに、それらを互いに連結するだけの作業で対応できるので、大型の部材がなく小型同士を積み重ねて連結するという極めて簡単な設置作業によって施工が行えることになる。しかも、前記各部間での穀物搬送経路として短いもので済ませることができ、長尺のシュートパイプ等を用いて穀物搬送経路を別途形成する等の煩わしい手間は不要である。
【００１３】
また、請求項２に記載の特徴構成によれば、前記選別部が、搬入された穀物の粗選別を行う粗選別部と、この粗選別部の下方側に位置して前記穀物の出荷用の精選別を行う精選別部とを備えて構成されている。
つまり、荷受け部に荷受けされて搬送されてくる穀物が、貯留部にて一時貯留され、この貯留部から供給される穀物が粗選別部にて粗選別が行われた後、計量部にて計量され、その後、乾燥処理や貯蔵処理等の後工程に移送されていく。又、乾燥処理や貯蔵処理が行われた後の穀物が、前記貯留部及び粗選別部の風選別部を介して精選別部に供給されて出荷用の精選別処理が行われて、且つ、計量処理の後、再度、貯蔵処理等の後工程に移送されていくことになる。従って、荷受け用の一連の処理が行われる装置部分だけでなく、穀物の出荷用の精選別や計量等の一連の処理が行われる装置部分が、上下方向に積み重ねられて一体的に組み付けられた構成となり、大型の部材がなく小型同士を積み重ねて連結するという極めて簡単な設置作業によって施工が行えることになる。
【００１４】
また、請求項２に記載の特徴構成によれば、下部側に位置する精選別部の構成体及び下部側に位置する計量部の構成体は、フレーム材が格子状に組み立てられた枠組体にて荷重を支持するように構成されているので、充分な強度にて荷重を支持する構成でありながら、例えば、メンテナンス作業やその他の作業を行うために、設置面と同一面（設備の床面）を移動することになる作業者が、枠組体のフレーム材の間の隙間から広い範囲にわたり目視で確認でき、見通しがよく作業が行い易いものとなる利点がある。
また、請求項２に記載の特徴構成によれば、前記各構成体の夫々に、それらが組み付けられた状態で上下方向に連通して穀物搬送用通路を構成する通路形成用筒部が形成され、前記穀物搬送用通路に、前記計量部にて計量が終了した後の前記穀物を次工程の移送用位置まで上揚搬送する搬送コンベアが備えられるとともに、塵埃吸引排気用のダクトが設けられている。
この種の穀物処理設備では、前記計量処理が終了した後、例えば、乾燥工程や貯蔵工程等の次工程への移送用位置まで、搬送コンベアにて穀物を上揚搬送させる構成となっているが、上記したように、積み重ねられる各構成体の夫々に形成した筒部により穀物搬送用通路が形成される構成とし、この穀物搬送用通路に、搬送コンベアが備えるとともに、塵埃吸引排気用のダクトが設けられる構成とすることによって、各構成体とは別に搬送コンベアの通路部分や前記ダクトを構成する場合に比べて、部材の兼用化によって、構成の簡素化を図ることができる。
【００１５】
請求項３に記載の特徴構成によれば、請求項１又は２において、上方側に位置する前記各構成体に点検架台が設けられ、この点検架台が連結具を介して建屋に連結支持されている。
【００１６】
この種の穀物処理設備において、前記各部の点検等のために作業者の足場となるための点検架台が設けられることなるが、この点検架台が連結具を介して建屋に連結支持されているので、複数の構成体が積み重ねられて背高になる場合であっても、上方側の適宜個所に位置する構造体が建屋に連結支持されることで、例えば、地震等の横揺れ荷重に対する合理的な支持構造を得ることができる。尚、建屋側から例えば連結梯子等を兼用する連結具にて連結支持するようにすれば、部材の兼用により、さらに構成の簡素化を図れるものとなる。
【００１８】
この種の穀物処理設備では、前記計量処理が終了した後、例えば、乾燥工程や貯蔵工程等の次工程への移送用位置まで、搬送コンベアにて穀物を上揚搬送させる構成となっているが、上記したように、積み重ねられる各構成体の夫々に形成した筒部により穀物搬送用通路が形成される構成とし、この穀物搬送用通路に、搬送コンベアが備えるとともに、塵埃吸引排気用のダクトが設けられる構成とすることによって、各構成体とは別に搬送コンベアの通路部分や前記ダクトを構成する場合に比べて、部材の兼用化によって、構成の簡素化を図ることができる。
【００１９】
【発明の実施の形態】
以下、本発明に係る穀物処理設備の実施の形態を、図面に基づいて説明する。図１に示すように、穀物処理設備は、納入者によって搬入され荷受け部に荷受けされた穀物の一例である穀粒の荷受け処理を行う荷受け処理部Ａ１，Ａ２、穀粒を貯蔵する貯蔵部と乾燥処理する乾燥処理部と合わせ持つ乾燥貯蔵部Ｂ、穀粒の籾摺調整を行う籾摺調整部Ｃ及び出荷処理を行う出荷部Ｄ等を備えて構成されている。
【００２０】
荷受け処理部は、第１荷受け処理部Ａ１と第２荷受け処理部Ａ２との２系統の荷受け経路が備えられ、１つの荷受け経路は、穀粒の荷受け処理時にのみ利用されるものであり、他方の荷受け経路は穀粒の荷受け処理時及び荷受けされている穀粒の出荷用の精選処理を行う時の夫々において利用される構成となっている。つまり、第１荷受け処理部Ａ１は、荷受けホッパー１（荷受け部の一例）にて受入れられた後、荷受けコンベア２にて横送りされ且つ第１揚送コンベア３により上揚搬送されて供給される穀粒を、一旦貯留する流量調整タンク４、穀粒から藁屑等の異物を除去するための粗選機５、粗選機５から排出される穀粒を計量する計量機６、計量機６から排出される計量後の穀粒を上揚搬送する第２揚送コンベア７等からなる。
そして、前記第２荷受け処理部Ａ２は、荷受けホッパー８（荷受け部の一例）にて受入れられた後、荷受けコンベア９にて横送りされ且つ第３揚送コンベア１０により上揚搬送されて供給される穀粒を、一旦貯留する流量調整タンク１１、穀粒から藁屑等の異物を除去するための粗選機１２、精選処理時には粗選機１２から排出される穀粒を精選別する精選機１３、荷受け処理時には粗選機１２から排出される穀粒を計量し、精選処理時には精選機１３から排出される穀粒を計量する計量機１４、粗選機１２から排出される枝梗付き籾等から枝梗等を除去する脱芒機１５、精選機１３から排出される脱ぷ米を貯留する脱ぷ米タンク１６、計量機１４から排出される計量後の穀粒を上揚搬送する第４揚送コンベア１７等からなる。
又、籾摺調整部Ｃには、調整タンク１８、籾摺調整装置１９、石抜機２０等が備えられ、出荷部Ｄには、計量タンク２１、出庫用計量機２２、自動給袋機２３等が備えられている。
【００２１】
前記乾燥貯蔵部Ｂは、図２に示すように、夫々が平面視で四角形状の穀粒空間を形成する貯留ビン２４の複数が並列配備される状態で設けられ、詳述はしないが、複数の貯留ビン２４のうちのいずれかのものを乾燥処理部として利用し、それ以外の貯留ビンを貯蔵処理部として利用する構成となっている。乾燥処理部では図示しない攪拌装置によって穀粒を攪拌しながら送風機によって送風させながら穀粒を乾燥処理するように構成されるとともに、送風機の送風力によって排出されて横送りコンベア２５に排出されるように構成されている。貯蔵処理部では、乾燥済みの穀粒を貯蔵するとともに、送風力によって排出されて横送りコンベア２５に排出されるように構成されている。
【００２２】
荷受け時において、第１荷受け処理部Ａ１では計量機６から排出される計量後の穀粒は第２揚送コンベア７によって揚送され、第２荷受け経路Ａ２では計量機１４から排出される計量後の穀粒は第４揚送コンベア１７によって揚送される。そして、供給用コンベア２６によって貯留ビン２４のいずれかに貯留されることになる。貯留ビン２４に貯留されて乾燥処理された穀粒は、各下端部の排出部２７から排出されて横送りコンベア２５及び各搬送コンベアにより貯蔵処理部を構成する貯留ビン２４に供給されて貯留され、精選処理時には、第２荷受け部Ａ２の第１揚送コンベア１０に搬送されて精選処理されたのち戻され、又、出荷処理時には、籾摺調整部Ｃに供給され更に出荷部Ｄを通して出荷されるようになっている。
【００２３】
前記第１荷受け処理部Ａ１における貯留部Ｘとしての流量調整タンク４、選別部Ｙの一例としての粗選機５、計量部Ｚとしての計量機６の夫々は上下方向に並べて備えられ、前記第２荷受け経路Ａ２においても同様に、貯留部Ｘとしての流量調整タンク１１、粗選別部としての粗選機１２及び精選別部としての精選機１３（これら粗選機１２及び精選機１３により選別部Ｙの他の例に相当する）、計量部Ｚとしての計量機１４の夫々は上下方向に並べて備えられる。
【００２４】
以下、具体的な構成について説明する。
図２〜図５に示すように、前記流量調整タンク１１は、平面視で四角形状の底無箱型のケーシング２７の内部に穀粒貯留用空間を形成するとともに、ケーシング２７の内部に漏斗状の傾斜案内部２８が付設され、その傾斜案内部２８の下端部に、図６に示すように、穀粒を帯状に広がった状態で流下案内させる開口部２９が形成されている。尚、この開口部２９には、穀粒を下方に流下供給する開状態と流下供給を停止する閉状態とに切り換え自在なシャッタ３０が設けられている。詳述すると、図１８に示すように、流量調整タンク１１は、中央の仕切板ｓｋにて仕切られた２つの穀粒貯留空間Ｔａ，Ｔｂを備えて構成され、供給される穀粒は２つの穀粒貯留空間Ｔａ，Ｔｂのうちのいずれかに選択的に供給されるようになっている。そして、前記各穀粒貯留空間Ｔａ，Ｔｂの下端部に開口Ｕが形成され、夫々エアーシリンダＣＹにて開閉操作自在な一対のシャッター３０，３０にてこの開口Ｕを開閉させて、開口部２９を通して穀粒を下方に流下供給する開状態と、流下供給を停止する閉状態とに切り換え自在となるように構成している。尚、前記開口Ｕ及び前記シャッター３０は、図１８の紙面表裏方向に沿って細長い帯状に形成されている。
【００２５】
前記粗選機１２は、平面視で前記流量調整タンク１１のケーシング２７と同一形状で、それと積み重ねて接続して連結可能な四角形の筒状であるケーシング３１が備えられ、この粗選機１２のケーシング３１は、流量調整タンク１１の荷重を支持することができるように強度メンバーとして構成されている。
前記粗選機１２の内部には、従来より周知の構成である粗選別用の部材が収納されている。つまり、図７に示すように、帯状に広がった状態で流下案内されてくる穀粒が、シリンダ３２の空気圧力により調節用部材３３の開閉具合を調節させることによって流下量が調節される繰り出しロール３４によって繰り出し案内されるように構成され、繰り出された穀粒が多数の穀粒通過用孔３５が形成される筒体であるスカルパーロール３６を通して穀粒は下方に流下し、通過しない枝梗付穀粒等をリスカルパーロール３７にて再度選別して枝梗付穀粒はスクリューコンベア３８にて横送りして外部に排出させるようになっている。尚、図中、３９は、スカルパーロール３６に対する供給案内板であり、４０はこの供給案内板３９の案内角度を変更調節するための手動操作式の調節機構である。
スカルパーロール３６やリスカルパーロール３７を通して流下した穀粒は、下方の排出口４１から下方の精選機１３に向けて排出されることになるが、このとき、図７に矢符にて示すように吸気口Ｑ１から排気口Ｑ２に向けて通流する選別風によって細かな塵埃が吹き飛ばされて回収スクリュー４２にて別途回収されるようになっている。
尚、粗選機１２から外部に排出される枝梗付穀粒は、図１６に示すようなリスレッシャーＲにより再脱穀処理が施されるようになっている。このリスレッシャーＲは、供給口４３から供給される穀粒（枝梗付穀粒）を、電動モータ４４により回転駆動される扱歯４５付きの処理胴４６によって扱き処理する構成となっている。
【００２６】
次に、精選機１３の構成について説明する。
精選機１３は、図８，図９に示すように、同一構成の精選装置４７，４７が左右一対並設されており、前記粗選機１２から流下供給される穀粒が、分配用スクリューコンベア４８にて分配されて、２台の精選装置４７，４７に振り分け供給されて並列的に選別処理するように構成され、選別処理された後の穀粒（整粒）は合流して計量機１４に供給され、枝梗付穀粒は脱芒機１５に供給され再処理された後、前記穀粒（整粒）に合流させる構成となっている。
【００２７】
前記分配用スクリューコンベア４８は、図１０に示すように、前記粗選機１２から幅広の帯状で流下供給される穀粒を受け止める案内樋４９が設けられ、この案内樋４９には搬送スクリュー５０が設けられるとともに、搬送スクリュー５０の底部案内面の中央部、並びに左右両端部の夫々に搬送スクリュー５０にて搬送される穀粒を下方に落下案内する案内筒５１，５２，５３が形成されている。中央の案内筒５１は前記穀粒を精選装置４７を迂回してそのまま計量部１４に供給するバイパス路として構成され、左右両側に位置する案内筒５２，５３が左右の精選装置４７，４７に夫々分配した状態で穀粒を供給させる供給路として機能するようになっている。
【００２８】
つまり、前記搬送スクリュー５０には、左右両側部に同一方向に駆動回転させても互いに穀粒搬送方向が異なるように傾斜姿勢が逆向きのスクリュー羽根５０ａ，５０ｂが形成され、搬送スクリュー５０を所定方向に回転させると、粗選機１２から流下供給される穀粒を全て前記中央の案内筒５１に向けて搬送する状態となり、搬送スクリュー５０を所定方向と逆方向に回転させると、粗選機１２から流下供給される穀粒を左右両側に位置する案内筒５２，５３に向けて振り分け搬送する状態となるように構成されている。
つまり、搬送スクリュー５０の回転方向を変更することで、荷受け処理時には精選装置４７を迂回してそのまま計量する状態に切り換え、精選処理時には粗選機１２から排出される穀粒を左右一対の精選装置４７，４７に振り分け供給して精選別する状態に切り換えて使用することができるように構成されている。
【００２９】
次に、精選装置４７の構成について説明する。尚、前記各精選装置は、同一構成であるから１つの構成についてのみ説明する。
図９に示すように、精選装置４７は、前記粗選機１２から流下供給される穀粒から枝梗付粒を分離除去する第１選別部４７Ａと、第１選別部４７Ａにおいて前記枝梗付粒が分離除去された被選別物を、整粒と脱ぷ粒とに分離して整粒を回収する第２選別部４７Ｂとで構成されている。
そして、前記第１選別部４７Ａは、図１１に示すように、ケーシング５４の内部に、電動モータＭ１によって回転駆動される筒状の第１回転体５６が設けられ、この第１回転体５６には、径方向外方側に向かって凹入する第１凹部５７が内周部の略全領域にわたって多数形成されるとともに、図１３に示すように、前記整粒及び前記脱ぷ粒が通過し且つ前記枝梗付粒の通過を阻止する枝梗付粒分離用の第１挿通孔５８が前記各第１凹部５７の底部個所に形成されている。前記第１凹部５７の開口部は、その開口部の大きさが、前記整粒及び前記脱ぷ粒が入り込み可能で且つ前記枝梗付粒が入り込み不能な大きさに設定されている。具体的には、第１凹部５７の開口部の直径が８．７ｍｍ程度に設定され、第１挿通孔５８の直径が７ｍｍ程度に設定されている。
【００３０】
第１回転体５６の内部にその軸芯方向一端側の供給口５９から、粗選機１２からの穀粒が供給されるとともに、穀粒が第１回転体５６の内部に沿って（図１１の右方向に向けて）移送されるに伴って、前記第１挿通孔５８を通過して径方向外方側に排出される前記整粒及び前記脱ぷ粒を受け止め回収して第１排出口６０に向けて搬送するスクリューコンベア６１が設けられている。又、第１回転体５６の前記第１挿通孔５８を通過せずに軸芯方向他端側から排出される前記枝梗付粒は第２排出口６２から外部（脱芒機１５）に排出される構成となっている。
前記スクリューコンベア６１、第１排出口６０、第２排出口６２、及び、それらへの穀粒案内部等により、分離供給手段Ｓ１が構成されることになる。
【００３１】
尚、第１回転体５６は、図８に示すように、その回転軸芯の一端側が上方に位置し、他端側が下方に位置するように傾斜姿勢に設定されるとともに、図１１に示すように、第１回転体５６の穀粒が供給される個所には回転駆動によって穀粒を他端側に向けて送り出す搬送スクリュー６３が設けられ、この搬送スクリュー６３による穀粒送り機構と前記軸芯が傾斜する構成とによって、穀粒を他端側に移送する移送手段ＩＳが構成されている。
【００３２】
前記第２選別部４７Ｂは、図１２に示すように、前記第１回転体５６とほぼ同様な構成で、電動モータＭ２によって回転駆動されるの筒状の第２回転体６４が設けられている。但し、この第２回転体６４に形成される各第２凹部６５には、脱ぷ粒が通過し且つ整粒の通過を阻止する脱ぷ粒分離用の第２挿通孔６６が形成されている。第２回転体６４の内部にその軸芯方向一端側の供給口６７より、第１選別部４７Ａにおける第１排出口６０から排出される穀粒が供給されるとともに、穀粒が第２回転体６４の内部に沿って（図１２の左方向に向けて）移送されるに伴って、前記挿通孔６６を通過して径方向外方側に排出される脱ぷ粒を受け止め回収して第３排出口６８に向けて搬送するスクリューコンベア６９が設けられている。又、第２回転体６４の前記第２挿通孔６６を通過せずに軸芯方向他端側から排出される整粒は第４排出口７０から外部（計量機１４）に排出される構成となっている。
【００３３】
又、第２回転体６４における前記各第２凹部６５は、その開口部の大きさが、脱ぷ粒が入り込むとともに、整粒が入り込まない大きさに設定され、第２回転体６４における第２凹部６５に入り込み且つ第２挿通孔６６を通過しない状態で、第２回転体６４の回転に伴って凹部６５が下向き姿勢になるまで回動されて、その凹部内から落下する穀粒（脱ぷ粒）を、第２回転体の内方側にて受け止める受け樋７１ａと、その穀粒を横送り搬送して回転体外部に排出させる搬送スクリュー７１ｂとからなる第２受止め回収部７１が備えられている。尚、この受止め回収部７１にて回収された穀粒（脱ぷ粒）は、前記第３排出口６８にてスクリューコンベア６９により搬送される穀粒（脱ぷ粒）と合流して外部（下方側の脱ぷ粒タンク１６）に排出される構成となっている。
具体的には、第２凹部６５の開口部の直径が、５．２ｍｍ程度に設定され、第２挿通孔６６の直径が３ｍｍ程度に設定されている。
前記スクリューコンベア６９、第３排出口６８、第４排出口７０、前記受止め回収部７１等により、分離回収手段Ｓ２が構成されることになる。
【００３４】
尚、第２回転体６４は、図８に示すように、その回転軸芯の一端側が上方に位置し、他端側が下方に位置するように傾斜姿勢に設定されるとともに、図１２に示すように、第２回転体６４の穀粒が供給される個所には回転駆動によって穀粒を他端側に向けて送り出す搬送スクリュー７２が設けられ、この搬送スクリュー７２による穀粒送り機構と、前記軸芯が傾斜する構成とによって、穀粒を他端側に移送する移送手段ＩＳが構成されている。尚、穀粒の移送方向は第１回転体５６と反対方向となっており、合理的な配置構成により設置スペースを少なくするようにしている。
【００３５】
前記脱芒機１５は、図１７に示すように、ホッパー７３に供給される枝梗付粒を電動モータ７４によって縦軸芯周りで回転駆動される複数の処理刃７５による扱き作用により単粒化処理して、処理済みの穀粒は案内シュート７６を介して計量機１４に供給するように構成されている。
【００３６】
そして、前記流量調整タンク１１、粗選機１２、精選機１３及び計量機１４等は、上下方向に並ぶ複数の構成体Ｋにて構成され、前記各構成体Ｋは、下側の構成体Ｋが上側の構成体Ｋの荷重を支持するように、順次積み重ねるとともに互いに連結して一体的に組み付けられ、最下段側の構成体が設置面に荷重が支持される状態で設置されて構成されている。
詳述すると、図５に示すように、前記計量機１４における排出用タンク１４ａが枠組みフレーム材Ｆに一体的に取り付け装着された第１構成体Ｋ１、前記計量機１４と前記脱ぷ粒タンク１６とが枠組みフレーム材Ｆに一体的に取り付け装着された第２構成体Ｋ２、前記精選機１３が枠組みフレーム材Ｆに一体的に取り付け装着された第３構成体Ｋ３、ケーシング３１が強度メンバーとして角筒状に構成された粗選機１２を構成する第４構成体Ｋ４、ケーシング２７が強度メンバーとして略箱型に構成された流量調整タンク１１を構成する第５構成体Ｋ５の夫々を、その記載順序で、下側から順次積み重ねるとともに互いに連結して一体的に組み付ける構成となっており、図４に示すように、最下段側の第１構成体Ｋ１が設置面Ｌ（当該設備のフロア面）に荷重が支持される状態で設置される構成となっている。
【００３７】
