【０００１】
【発明の属する技術分野】
この発明は、籾摺選別機に関するものである。
【０００２】
【従来の技術】
籾摺部、摺落米風選部及び揺動選別部を具備する籾摺選別機において、摺落米風選部には籾摺部からの摺落米を風選する摺落米風選路を設けて、摺落米風選路の終端部を吸引ファンの吸入部に接続し、揺動選別部で分離選別した玄米を取り出す玄米揚穀機の穀粒取出部に吸塵風路の始端側を接続し、吸塵風路の終端部を摺落米風選部の吸引ファンの吸入部に接続し、機外に取り出される玄米から吸塵するものは公知である。
【０００３】
【発明が解決しようとする課題】
従来装置では、玄米揚穀機から取り出される玄米から塵埃を吸塵除去するものの、吸塵性能が十分ではなく、吸塵能力の向上が要望されていた。そこで、この発明は、揺動選別部から玄米揚穀機に流下中の玄米から吸塵すると共に、玄米揚穀機から機外に取り出される玄米からも吸塵して吸塵性能を向上させ、また、玄米から吸塵する吸塵風路の清掃を容易化しようとするものである。
【０００４】
【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、請求項１の発明は、籾摺部１、摺落米風選部２と、揺動選別部３と、揺動選別部３で分離選別した玄米を機外に取り出す玄米揚穀機５とを具備し、摺落米風選部２には籾摺部１からの摺落米を風選する摺落米風選路１０と吸引ファン１３とを設け、摺落米風選路１０の終端部を吸引ファン１３の吸引口部１３ｂに接続する構成とし、玄米揚穀機５には取出棚５ｃを備える穀粒取出部５ｂを設け、穀粒取出部５ｂには吸塵風路２８の始端側を接続し、吸塵風路２８の終端部は摺落米風選部２の吸引ファン１３の吸引口部１３ｂに接続する構成とし、揺動選別部３で分離選別された玄米を玄米揚穀機５に流下供給する玄米流路２１には第２吸塵風路２９の始端部を連通し、第２吸塵風路２９の終端部は前記吸塵風路２８の中途部に連通する構成とし、第２吸塵風路の途中部には通路を開閉する開閉弁３０を設け、摺落米風選路１０の終端部には摺落米風選路１０と吸引ファン１３の吸引口部１３ｂとを連通状態か遮断状態に調節する風路開閉手段３２を設けたことを特徴とする。
【０００５】
【発明の作用及び効果】
請求項１の発明は、籾摺部１で籾摺りされた摺落米は摺落米風選部２の摺落米風選路１０で吸引ファン１３により風選される。そして、揺動選別部３で選別された玄米は玄米流路２１を経て玄米揚穀機５に流下し、穀粒取出部５ｂから機外に取り出される。
玄米が玄米流路２１を流下中に第２吸塵風路２９により塵埃が吸塵除去される共に、玄米揚穀機５から機外に取り出される際にも穀粒取出部５ｂの取出棚５ｃを流下中に塵埃が吸塵風路２８に吸塵される。そして、第２吸塵風路２９の塵埃は吸塵風路２８を経由して、吸塵風路２８の終端部から吸引ファン１３、排塵筒１４を経て機外に排出される。このとき、風路開閉板３２を風路開状態に調節すると、摺落米風選路１０及び吸塵風路２８から風が流れて、摺落米風選路１０で摺落米の風選をし、吸塵風路２８で玄米の吸塵をする。また、風路開閉板３２を閉状態に調節すると、摺落米風選路１０との接続部が閉鎖されて、吸塵風路２８からだけ吸引ファン１３に風が流れる。また、開閉弁３０を閉鎖すると第２吸塵風路２９からは吸引しない。
【０００６】
従って、揺動選別部３で選別された玄米は、玄米揚穀機５に流下する途中の玄米流路２１で吸塵され、更に、玄米揚穀機５で揚穀されて機外に取り出す際にも再度吸塵されるので、玄米の吸塵能力を向上することができる。また、風路開閉板３２を閉状態に調節すると、摺落米風選路１０との接続部が閉鎖されて、吸塵風路２８からだけ吸引ファン１３に風が流れて、吸塵風路２８の吸塵能力を高め、吸塵風路２８の清掃をすることができる。さらに、第２吸塵風路２９の開閉弁３０を閉鎖し、第２吸塵風路２９から吸引しないようにすると、吸塵風路２８の始端側の吸塵能力を高めることができ、吸塵風路２８の始端側に停滞している塵埃類を吸引ファン１３に吸引除去し吸塵通路２８の清掃をすることができる。
【０００７】
【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からの風選後の混合米を籾・玄米に分離選別する揺動選別部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。
【０００８】
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，摺落米風選路１０，粃受樋１１，摺落米受樋１２，吸引フアン１３，排塵筒１４等により構成されている。次に、揺動選別部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した構成とし、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で、横方向斜め上下に往復揺動される構成である。
【０００９】
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を経由して供給口から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、また、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、また、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。
【００１０】
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に揚穀還元されて、再度の籾摺がなされる構成である。
【００１１】
次に、図２及び図３に基づきバケット型の玄米揚穀機５の吸塵構成について説明する。バケット型の玄米揚穀機５は、揚穀ケース５ａ、揚穀ケース５ａの上・下端部に回転自在に軸架されている揚穀プーリ（図示省略）、揚穀プーリに巻き掛けられている揚穀ベルト（図示省略）、揚穀ベルトに取り付けられているバケット（図示省略）、揚穀穀粒を取り出す取出ボックス５ｂ等により構成されている。しかして、揚穀ケース５ａ内をバケットにより揚穀された穀粒は取出ボックス５ｂに投げ出され、取出棚５ｃ，５ｃ，…をジグザグに流下しながら取出口５ｄから取り出される。
【００１２】
取出ボックス５ｂには吸塵風路２８の始端側を接続し、吸塵風路２８の中途部を玄米揚穀機５に沿って下方に導き、次いで、摺落米風選箱９の底部に構成した吸塵風路２８を経て機体前部に導き、吸塵風路２８の終端部を幅広部２８ａに構成し、吸引ファン１３の左右両側の吸入部に接続している。また、吸塵風路２８の中途部から第２吸塵風路２９を分岐し、第２吸塵風路２９の始端部を前記玄米流路２１に臨ませ、第２吸塵風路２９の中途部には通路を開閉する開閉弁３０を設けている。なお、バケット型の玄米揚穀機５をスローワ型の玄米揚穀機５に代え、穀粒の取出部に吸塵風路２８を接続してもよい。
【００１３】
しかして、揺動選別部３で選別され玄米は玄米流路２１を流下中に第２吸塵風路２９により吸塵除去され、また、玄米揚穀機５から機外に取り出される玄米は取出ボックス５ｂを流下中にも吸塵風路２８により吸塵されて、これらの塵埃は吸塵風路２８を経由して吸引ファン１３に吸引され排塵筒１４を経て機外に排出される構成である。
【００１４】
従って、揺動選別部３で選別し取り出された玄米は、玄米揚穀機５に流下する途中の玄米流路２１で吸塵され、更に、玄米揚穀機５から機外に取り出される際にも再度吸塵されて、玄米の吸塵能力を向上することができる。なお、第２吸塵風路２９の開閉弁３０を閉鎖し、第２吸塵風路２９から吸引しないようにすると、吸塵風路２８の始端側の吸塵能力を高めることができ、吸塵風路２８の始端側に停滞している塵埃類を吸引ファン１３に吸引除去し吸塵通路２８の清掃をすることができる。
【００１５】
次に、図４に基づき吸塵風路２８の吸引ファン１３への接続構成の他の実施例について説明する。吸引ファン１３の吸引ファンケース１３ａには左右両側に吸引口部１３ｂ，１３ｂを設け、吸引ファンケース１３ａの排風部に排塵筒１４を接続している。吸引ファンケース１３ａにおける一側の吸引口部１３ｂの下部を、吸塵風路２８の終端部に接続されている掃除ボックス３１を接続して、吸塵風路２８から掃除ボックス３１を経て吸塵風が吸引ファンケース１３ａに吸引される構成である。また、吸引ファンケース１３ａにおける一側の吸引口部１３ｂの上部、及び、他側の吸引口部１３ｂ全体から、摺落米風選路１０からの選別風を吸引する構成としている。なお、掃除ボックス３１には掃除口３１ａを設け、開閉板３１ｂにより開閉できる構成としている。
【００１６】
吸引ファンケース１３ａの一側の吸引口部１３ｂに風路開閉板３２を回転自在に設け、図４（２）に示す風路開状態に調節すると、一側の吸引口部１３ｂの上下が通風状態となり、摺落米風選路１０及び吸塵風路２８から風が流れて塵埃類を吸引する。また、図４（３）に示すように、風路開閉板３２を閉状態に調節すると、摺落米風選路１０との接続部が閉鎖されて、吸塵風路２８からだけ風が流れ塵埃を吸引する。
【００１７】
しかして、作業中は風路開閉板３２を開状態とし、摺落米風選路１０及び吸塵風路２８から風が流れるようにし、摺落米風選路１０で摺落米を風選し、吸塵風路２８から玄米の吸塵をする。また、風路開閉板３２を閉状態に調節すると、摺落米風選路１０との接続部が閉鎖されて、吸塵風路２８からだけ吸引ファン１３に風が流れて、吸塵風路２８の吸塵能力を高め、吸塵風路２８の清掃をすることができる。
【００１８】
なお、前記風路開閉板３２に代えて、摺落米風選路１０の風路内に風路を開閉できる風路開閉板を設けても同様の効果が期待できる。次に、図５及び図６について説明する。摺落米風選箱９の粃受樋１１の下方に粃ボックス３３を配置して、粃受樋１１に選別された粃を粃ボックス３３に貯溜できる構成としている。この粃ボックス３３の底部には粃開閉板３４を設けて、摺落米風選箱９の底部に構成した吸塵風路２８と連通したり閉鎖したりできる構成としている。
【００１９】
しかして、作業終了時には、粃開閉板３４を開調節し粃ボックス３３の底部を吸塵風路２８に連通すると、粃ボックス３３の粃が吸塵風路２８に流下し、吸引ファン１３、排塵筒１４を経由して機外に排出することができ、粃の排出処理を楽に行なうことができる。
【００２０】
次に、図７に基づき籾摺選別機から取り出した玄米を選別する縦型粒選別機３５の袋保持装置について説明する。縦型粒選別機３５は公知のもので、同一の縦軸心回りに回転する大径の選別網筒及び小径の揚穀ラセン筒、投入ホッパ、選別された精粒を取り出す精粒ホッパ、小形の屑米の選別される屑米室等から構成されていて、下部に供給された穀粒を揚穀ラセン筒により選別網筒内を揚穀しながら、小粒の穀粒を選別網筒から外側の屑米室に排出し、精粒の穀粒を上方まで揚穀して精粒ホッパに取り出すものである。
【００２１】
この縦型粒選別機３５には、図７（１）に示すように、上部四隅に袋支持棒３６，３６，…を上方に突出するように設けて、穀粒袋３７を支持する構成である。このように縦型粒選別機３５の上部に袋支持棒３６，３６，…により穀粒袋３７を保持しているので、オペレータは腰をかがめずに穀粒袋３７を取り出すことができて、楽に粒選別作業をすることができる。
【００２２】
また、図７（２）に示すように、袋保持棒３８を上下回動自在に軸支して袋を保持する構成としてもよい。縦型粒選別機３５の上部に上下回動する袋保持棒３８を介して穀粒袋３７を上方から押圧保持するので、機体の振動によっても穀粒袋３７が落下することもなく、楽に粒選別作業をすることができる。
【００２３】
次に、図８により籾摺部１の他の実施例について説明する。籾ホッパ６の下方の籾摺室８に一対の籾摺ロール７，７を配置し、籾ホッパ６の流下口近傍には左右一対の掻き込みロール４０，４０を軸架し、掻き込みロール４０，４０を下方の籾摺ロール７，７に接近して互いに反対方向に回転するように軸架している。そして、左右の掻き込みロール４０，４０と籾ホッパ６，６との間には、籾ホッパ６の左右両側部に形成した籾流下通路流４１，４１から穀粒が入できる構成とし、籾摺ロール７，７の下方には、左右一対の拡散羽根４２、４２を回転自在に軸架している。
【００２４】
籾ホッパ６に籾を供給すると、例えば、１２００ｒｐｍの高速回転している掻き込みロール４０と５００ｒｐｍ程度の低速回転している籾摺ロール７との間に籾が供給されて、半脱ぷあるいは籾に傷が付けられる程度の一次の籾摺がなされる。次いで、例えば、低速回転している一方の５００ｒｐｍ程度の籾摺ロール７と他方の３８０ｒｐｍ程度の籾摺ロール７により二次の籾摺がなされ、摺落米は左右の拡散羽根４２、４２の中間部に落下供給されて拡散し、玄米に籾殻の付着している半脱ぷ米は玄米と籾殻とが衝撃的に分離させる。
【００２５】
前記のように、掻き込みロール４０，４０と籾摺ロール７，７により一次の籾摺をし、籾摺ロール７，７で二次の籾摺をするので、脱ぷ性能を向上させることができ、また、二次の摺落米を柔軟性材の拡散羽根４２、４２により衝撃的に拡散するので、半脱ぷ米の籾殻を良好に玄米から分離することができる。
【００２６】
次に、図９により籾摺部１の他の実施例について説明する。籾選別ボックス４３と摺落米選別ボックス４４とを左右に併設し、籾選別ボックス４３の上部に籾ホッパ６を配置し、籾ホッパ６の下方に籾選別風路４５を配置し、籾選別風路４５の下方に１番受樋４６及び２番受樋４７を配置し、籾選別風路４５の終端部を吸引ファン１３に連通している。１番受樋４６には１番ラセン４８を回転自在に支架し、１番ラセン４８の軸端部には例えば２０００ｒｐｍ〜２３００ｒｐｍで標準回転する第１インペラ型籾摺装置５１を取り付け、また、２番受樋４７には２番ラセン４９を回転自在に支架し、２番ラセン４９の軸端部には例えば２８００ｒｐｍで高速回転する第２インペラ型籾摺装置５２を取り付けている。
【００２７】
第１・第２インペラ型籾摺装置５１，５２で籾摺された脱ぷ米は移送通路５３を経て摺落米選別ボックス４４の摺落米ホッパ５４に供給される。次いで、脱ぷ米は摺落米風選路１０に供給されて風選され、籾殻類は吸引ファン１３、排塵筒１４を経て機外に排出され、風選された混合米は揺動選別部（図示省略）に送られ籾・玄米に分離選別される。
【００２８】
前記のように、籾を風選した精籾を標準回転の第１インペラ型籾摺装置５１に供給して脱ぷするので、玄米の損傷を防止することができる。また、粃等の２番穀粒は高速回転の第２インペラ型籾摺装置５２に供給して脱ぷするので、脱ぷ率を高めて能率的に籾摺することができる。
