【発明が解決しようとする課題】
従来の粃選別装置は、摺落米風選路の粃選別口に選別された粃を粃流下路を経由して粃受樋に流下するように構成し、粃流下路には下方から上方に粃選別風が流れるように構成し、摺落米風選路には粃選別風の風量を調節する粃風量調節弁を設けているので、粃受樋に選別される粃量を調節できるが、機外に排出する粃は摺落米風選路を経て吸引ファンに送られ、摺落米風選路の選別に悪影響を及ぼすことがある。
【０００５】
そこで、この発明はこのような不具合を防止し、粃受樋に選別される粃を直接吸引ファンに送って機外に排出し、摺落米風選路へ選別影響を少なくしながら粃選別量を調節しようとするものである。
【０００６】
【課題を解決するための手段】
このような問題点を解決するために、次のような技術的手段を講じた。
請求項１の発明は、終端部に吸引ファン１３の設けられている摺落米風選路１０の始端側下方には摺落米受樋１２を、中途部下方には粃受樋１１の粃選別口１１ａを夫れ夫れ設け、粃選別口１１ａから粃受樋１１に粃を流下する粃流下路１１ｂを粃連通路３３，３３、排塵通路１０ａ，１０ａを経て吸引ファン１３の吸引部に連通し、前記粃連通路３３，３３には風量を調節しながら連通したりあるいは遮断する風力調節弁３４，３４を設けたことを特徴とする。
【０００７】
請求項１の発明では、摺落米風選路１０に供給された摺落米は吸引ファン１３で生起された選別風により風選され、重い籾・玄米は始端側下方の摺落米受樋１２に選別され、比較的軽い粃は中途部下方の粃選別口１１ａに選別され粃流下路１１ｂを経て粃受樋１１に流下し、軽い籾殻類は吸引ファン１３を経て機外に排出される。
【０００８】
また、粃連通路３３，３３の風力調節弁３４，３４を吸引ファン１３に対して遮断状態とすることにより、粃選別口１１ａに選別されて粃を粃受樋１１に全量回収することができ、また、風力調節弁３４，３４を風量を調節しながら吸引ファン１３に連通状態とすることにより、粃選別口１１ａに選別された粃の一部を、粃連通路３３，３３、排塵通路１０ａ，１０ａを経由して粃量を調節しながら吸引ファン１３に送り機外に排出するすることができる。
【０００９】
請求項２の発明は、終端部に吸引ファン１３の設けられている摺落米風選路１０の始端側下方に摺落米受樋１２を設け、摺落米風選路１０の中途部下方には、選別始端側に第１粃選別口１１ｃ、選別終端側に第２粃選別口１１ｄを夫れ夫れ設け、これらの第１・第２粃選別口１１ｃ，１１ｄを夫れ夫れ第１・第２粃流路４１，４２を経て粃受樋１１に接続し、選別終端側の前記第２粃流路４２には吸引ファン１３の吸引部に連通状態としたり、あるいは、閉鎖して機外取出状態に切り替える切替弁４３を設けたことを特徴とする。
【００１０】
請求項２の発明では、摺落米風選路１０に供給された摺落米は吸引ファン１３で生起された選別風により風選され、重い籾・玄米は始端側下方の摺落米受樋１２に選別され、軽い籾殻類は吸引ファン１３を経て機外に排出される。また、比較的軽い粃の内、大きな粃は選別始端側の第１粃選別口１１ｃに選別され、小さな粃は選別終端側の第２粃選別口１１ｄに選別され、これらの粃は夫れ夫れ第１・第２粃流路４１，４２を経て粃受樋１１に回収される。また、選別終端側の第２粃流路４２の切替弁４３を吸引ファン１３側に連通状態とすることにより、小さな粃だけを吸引ファン１３を経て機外に排出することができる。
【００１１】
【発明の効果】
請求項１の発明は、粃選別口１１ａに選別された粃を機外に排出する際には、粃連通路３３，３３を経て吸引ファン１３に送り機外に排出するので、摺落米風選路１０の選別への影響を少なくすることができる。
【００１２】
請求項２の発明は、選別始端側の第１粃選別口１１ｃには比較的大きな粃を、また、選別終端側の第２粃選別口１１ｄには比較的小さな粃を選別して粃選別の精度を向上させることができ、また、比較的小さな粃の流下する第２粃流路４２に設けられている切替弁４３を切り替えることにより、比較的小さな粃だけを吸引ファン１３を経て機外に排出すことができ、摺落米風選路１０の選別への影響を少なくしながら粃処理精度を向上させることができる。
【００１３】
【発明の実施の形態】
以下、図面に示すこの発明の実施例の形態について説明する。
まず、図１に基づき籾摺選別機の全体構成について説明する。
籾摺選別機は、籾摺部１、籾摺部１からの摺落米を風選する摺落米風選部２、摺落米風選部２からの混合米を籾・玄米に分離選別する揺動選別型の混合米選別部３、混合米揚穀機４及び玄米揚穀機５等により構成されている。
【００１４】
籾摺部１は、籾ホッパ６，籾摺ロ−ル７，７の内装されている籾摺室８等で構成されている。摺落米風選部２は、摺落米風選箱９、摺落米風選箱体９内に前後方向（図１では左右方向）に斜設されていて、後側部を選別始端側とし、前側部を選別終端側とする摺落米風選路１０、摺落米風選路１０の前後方向中途部下方に設けられている粃受樋１１、摺落米風選路１０の始端側下方に設けられている摺落米受樋１２、摺落米風選路１０の終端部に連通して設けている吸引フアン１３、排塵筒１４等により構成されている。
【００１５】
しかして、籾摺ロール７，７で摺落された摺落米が摺落米風選路１０に供給され、選別風により風選される。重い籾・玄米の混合米は摺落米風選路１０始端側の摺落米受樋１２に落下選別され、比較的軽い粃は摺落米風選路１０中途部の粃受樋１１に落下選別され、軽い籾殻類は終端側に流れ吸引ファン１３、排塵筒１４を経て機外へ排出される。
【００１６】
次に、揺動選別型の混合米選別部３について説明する。多段の揺動選別板１５，１５，…には、板面に選別用の凹凸が形成されていて、縦方向の一側を高い供給側、他側を低い排出側とし、横方向の一方側を高い揺上側、反対側を低い揺下側として、揺動選別板１５の縦方向及び横方向を共に傾斜させ、揺動選別板１５，１５，…は揺動アーム，揺動リンク等から構成されている揺動装置により、横方向斜め上下に往復揺動される構成である。
【００１７】
この揺動選別板１５，１５，…の供給側には供給口が構成されていて、混合米揚穀機４からの混合米が、混合米ホッパ２４，分配供給樋１６及び分配ケース１７を経て供給される構成である。揺動選別板１５，１５，…に供給された混合米は、粒形の大小，比重の大小，摩擦係数の大小等の関係で、比重の重い小形の玄米は揺上側に偏流分布し、玄米に比較して大きく比重の軽い籾は、揺下側に偏流分布し、その中間部には分離されない籾・玄米の混合米が分布しつつ選別される。そして、これらの選別穀粒は、揺動選別板１５の排出側に設けられている玄米仕切板１８及び籾仕切板１９で仕切られて取り出される。
【００１８】
取り出された玄米は、玄米取出樋２０，玄米流路２１，玄米揚穀機５を経て機外に取り出され、また、混合米は混合米取出樋２２，混合米流路２３，摺落米受樋１２，混合米揚穀機４，混合米ホッパ２４，分配供給樋１６，分配ケース１７を経て、揺動選別板１５，１５，…に供給されて再選別される。また、取り出された籾は、籾取出樋２５，籾流路２６，籾揚穀機２７を経て籾摺部１に揚穀還元され、再度の籾摺がなされる構成である。
【００１９】
次に、図２〜図４に基づき摺落米風選部２の粃風選構成について説明する。
摺落米風選路１０の終端部下方には、機体の左右方向中央部に吸引ファン１３の吸引ファン胴１３ａを配置している。従って吸引ファン１３による選別風は左右に分かれ、摺落米風選路１０の終端部から左・右排塵通路１０ａ，１０ａを経て吸引ファン胴１３ａの左・右吸引口１３ｂ，１３ｂから籾殻等を吸引し、吸引ファン胴１３ａの前側下部の排塵口１３ｃを経て排塵筒１４に籾殻等を排出するように構成している。
【００２０】
また、摺落米風選路１０の前後方向中途部下方には、粃棚先３１の終端側寄りに左右方向全幅にわたって粃選別口１１ａを設け、粃選別口１１ａの下方には粃受樋１１を設けて、粃選別口１１ａに選別された粃を粃流下路１１ｂを経て取出可能に構成している。
【００２１】
また、粃選別口１１ａの左右両側部には、前側に向けて上り傾斜の粃連通路３３，３３を構成している。この粃連通路３３，３３の前側終端部を前記左・右排塵通路１０ａ，１０ａに風力調節弁３４，３４を介して連通している。しかして、風力調節弁３４，３４を全閉鎖にして、粃を全量粃受樋１１に取り出したり、あるいは、風力調節弁３４，３４により粃連通路３３，３３の風量を調節しながら、粃選別口１１ａに選別された粃量を調節して粃連通路３３，３３、左・右排塵通路１０ａ，１０ａを経て吸引ファン１３に送ることができる。
【００２２】
従って、粃の品質により機外排出や粃取出に切り替えたり、あるいは、籾殻と共に機外に排出する粃量を調節しながら粃受樋１１に回収することができる。
なお、粃連通路３３は、実施例に示すようにファン胴１３ａの左右側に構成するほか、ファン胴１３ａの背面を切除して左右中央側から吸引しうる構成でもよい。
【００２３】
次に図５に基づき粃選別装置の他の実施例について説明する。
摺落米風選箱体９には摺落米風選路１０を斜設し、摺落米風選路１０の前後方向中途部下方には、左右方向全幅にわたって粃選別口１１ａを構成し、粃選別口１１ａの下方に板体で仕切られた粃選別空間部３５を構成している。粃選別空間部３５の中間部には粃受樋１１を配置し、粃選別口１１ａに選別された粃を、粃流下路１１ｂを経て粃受樋１１に流下可能に構成し、粃受樋１１の底部には粃ラセン３６を配設して、粃を左右一側に搬送し、粃ラセン揚穀機３７により籾摺部１に揚穀し又は機外に排出可能に構成している。
【００２４】
また、粃選別空間部３５の上部前側位置には、粃選別口１１ａの左右両側部に前上りに傾斜している粃連通路３３，３３を設け、この左右の粃連通路３３，３３の後端部内側を粃流下路１１ｂに開口して臨ませ、粃連通路３３，３３の前側終端部を前記左・右排塵通路１０ａ，１０ａに風力調節弁３４，３４を介して連通している。
【００２５】
そして、粃選別空間部３５の後側下部には吸気口３８を設けて、吸気口３８には開閉弁３９を開閉調節自在の設け、吸気口３８から流入した粃選別風が摺落米風選路１０底板下方に沿って流れ、更に粃受樋１１の上方を通過して粃連通路３３，３３に流れるように構成している。
【００２６】
しかして、粃選別空間部３５の吸気口３８から流入した選別風が、粃受樋１１の上方を経て粃連通路３３，３３の始端部に流入し、左・右排塵通路１０ａ，１０ａを経て吸引ファン１３に流れ、この選別風により粃が機外に排出される。
従って、選別された粃を粃連通路３３，３３を経て吸引ファン１３に送り機外に排出するので、摺落米風選路１０の選別風が粃連通路３３，３３に流れるようなこともなく、粃選別風の摺落米風選路１０への流入を少なくし摺落米風選路１０への影響を少なくすることができる。
【００２７】
なお、前記開閉弁３９を開閉ぺダル（図示省略）で操作し、吸気口３８の開閉調節をするように構成してもよい。
また、図６に示すように、粃連通路３３，３３の前側終端部を前記左・右排塵通路１０ａ，１０ａに連通し、粃連通路３３，３３の前側終端部に前風力調節弁３４ａ，３４ａを開閉自在に軸支し、後側始端部にも後風力調節弁３４ｂ，３４ｂを開閉自在に軸支し、これらの前・後風力調節弁３４ａ，３４ｂをロッド４０により連動連結し、同時に開閉するように構成してもよい。
【００２８】
このように前後の風力調節弁を設けてた互いに連動するよう構成することにより、粃連通路３３，３３を前・後風力調節弁３４ａ，３４ｂにより閉鎖すると、粃選別口１１ａに近い粃連通路３３，３３の後側始端部が後風力調節弁３４ｂ，３４ｂにより閉鎖されて、摺落米風選路１０から籾殻や塵埃類を含んだ選別風の粃連通路３３，３３への巻き込み流入を阻止し、摺落米風選路１０の選別風の乱れを少なくすることができる。
【００２９】
次に、図７に基づき粃選別装置の他の実施例について説明する。
摺落米風選箱体９には摺落米風選路１０を斜設し、摺落米風選路１０の前後方向中途部下方には、左右方向全幅にわたって第１粃選別口１１ｃを、その終端側寄りに第２粃選別口１１ｄを設けている。第１・第２粃選別口１１ｃ，１１ｄの下方に板体で仕切られた粃選別空間部３５に構成し、第１・第２粃選別口１１ｃ，１１ｄで選別された粃を第１・第２粃流路４１，４２を経て粃受樋１１に流下し、粃ラセン３６により粃を左右一側に搬送し、粃ラセン揚穀機３７を経て籾摺部１に揚穀可能に構成している。
【００３０】
第２粃流路４２の下部には切替弁４３を設け、第２粃流路４２の粃を粃受樋１１に流下案内したり、機外取出に切り替えるように構成している。また、粃選別空間部３５の後側下端部には吸気口３８を設けて、吸気口３８から流入した粃選別風が第１・第２粃流路４１，４２、第１・第２粃選別口１１ｃ，１１ｄを経て摺落米風選路１０に流れるように構成している。
【００３１】
しかして、風選部に作用する風力との関係で、第１粃選別口１１ｃには比較的比重の大きな粃が選別され、第２粃選別口１１ｄには比較的比重の小さな粃が選別され、第１・第２粃流路４１，４２を経て粃受樋１１に流下する。また、第２粃流路４２の下部に設けられている切替弁４３を切替調節することにより、第２粃流路４２に選別された比較的小さな粃だけを機外に取り出すことができて、粃選別精度を向上させることができる。
【００３２】
また、図８に示すように、第２粃選別口１１ｄ及び第２粃流路４２を一体的に構成して、摺落米風選箱体９に対して前後方向、すなわち選別風流動方向前後に移動調節自在に構成して、第２粃選別口１１ａを摺落米風選路１０に対して前後に調節してもよい。このようにすることにより、被選別物の粃の状態に応じて第２粃選別口１１ｄを前後に調節して第２粃選別口１１ｄに比較的小さな粃を取り出すようにし、粃受樋１１に回収したり、機外に取り出したりし、粃選別精度の向上を図ることができる。
【００３３】
次に、図９に基づき粃選別装置の他の実施例について説明する。
摺落米風選箱体９には摺落米風選路１０を斜設して、摺落米風選路１０の終端部には一番風力調節弁４４を設け、吸引ファン１３には回転数調節レバー４５を設けて、摺落米風選路１０の選別風量を調節可能に構成している。摺落米風選路１０の前後方向中途部下方には粃選別口１１ａを設け、粃選別口１１ａに選別された粃を粃流下路１１ｂを経て粃受樋１１を供給するよう構成している。粃流下路１１ｂの下端部には二番風力調節弁４６を設けている。
【００３４】
また、粃流下路１１ｂの下方には並行して左右の粃連通路３３，３３を構成し、粃連通路３３，３３の終端部を前記左・右排塵通路１０ａ，１０ａ、左・右吸引口１３ｂ，１３ｂを経由して吸引ファン１３に連通している。この粃連通路３３，３３の始端部を粃流下路１１ｂの下端部に臨ませ、粃連通路３３，３３の中途部に粃量調節弁４７を設けている。
【００３５】
しかして、二番風力調節弁４６を調節することにより、摺落米風選路１０の一番選別風を変化させずに、粃選別口１１ａに流れる二番風量を調節することができ、また、粃量調節弁４７を調節して粃連通路３３，３３から吸引ファン１３に排出する粃量を調節することができる。
【００３６】
次に、図１０に基づき摺落米風選部２の他の実施例について説明する。
摺落米風選箱体９には摺落米風選路１０を斜設し、摺落米風選路１０の始端側下方に摺落米受樋１２を設け、摺落米風選路１０の前後方向中途部下方に粃受樋１１を設け、摺落米風選路１０の終端部に吸引ファン１３を設けている。摺落米風選箱体９の上面部を籾摺部１の据付台４８に構成し、据付台４８に籾摺部１を載置している。この据付台４８を後傾斜に構成して、据付台４８の後端部に開口部４９を設けて、摺落米風選路１０の始端部上方に開口部４９を連通している。なお、据付台４８を防音材で構成してもよい。
【００３７】
しかして、籾摺部１の籾ホッパ６から飛散した穀粒が傾斜した据付台４８上に落下すると、機体の震動により据付台４８上を後側に流動し、開口部４９を経て摺落米風選路１０に回収され、風選され再処理される。なお、籾摺部１の周辺に飛散している塵埃を開口部４９を経て摺落米風選路１０に吸引することができる。
【００３８】
また、図１１に示すように、据付台４８を操作側である手前側に下り傾斜に構成し、据付台４８の手前側には籾摺ロール７，７の内装されている籾摺室８を配置し、後側に伝動用のギヤボックス５０を配置するように構成してもよい。このように構成することにより、据付台４８上に飛散した穀粒を震動により据付台４８の手前側に集めることができて、穀粒の清掃を容易なものとすることができる。
【００３９】
次に、図１２に基づき混合米揚穀機４の揚穀ベルトの張り調節装置について説明する。
揚穀ケース５１の上部には、上部揚穀金車５２を軸支した調節揚穀ケース５３を上下摺動自在に取り付け、調節揚穀ケース５３の支持プレート５４には、左右のアーム５５，５５をピン連結して、左右方向に回動自在に支持している。揚穀ケース５１における調節揚穀ケース５３の下方部位には、Ｕ字状のベース板５６を介して調節ねじ棒５７を軸架し、調節ねじ棒５７のねじ部には左右のねじ筒５８、５８をねじ嵌合し、前記左右のアーム５５，５５の下端部を左右方向に傾斜状にしてねじ筒５８，５８にピン連結している。
【００４０】
調節ねじ棒５７の端部にはギヤ５９を取り付け、ハンドル６０をギヤ５９部に遊転自在に嵌合し、ハンドル６０の内周部にはバネ材６１を介して爪体６２を取り付けて、爪体６２をギヤ５９に係合している。
しかして、ハンドル６０を介して調節ねじ棒５７を正転あるいは逆転することにより、アーム５５，５５を介して調節揚穀ケース５３が上下方向に移動調節され、上部揚穀金車５２に巻き掛けられている揚穀ベルトを緊張・弛緩調節することができる。
【００４１】
また、調節操作中に揚穀ベルトが所定の緊張度に達すると、バネ材６１が外周側に移動して、爪体６２がギヤ５９から外れ、これ以上の緊張調節が中止される。従って、簡単な構成でありながら、揚穀ベルトを所定張力に容易に調節できて、安定した揚穀をすることができる。
【００４２】
なお、調節ねじ棒５７の端部にハンドル６０を直接固着する構成としてもよい。
