Description

【０００１】
【発明の属する技術分野】
本発明は、穀物を乾燥して貯留する穀物乾燥貯留設備に関する。
【０００２】
【従来の技術】
この種の穀物乾燥貯留設備では、穀物を乾燥処理する乾燥用の貯留部や、この乾燥用の貯留部にて乾燥された穀物を貯蔵処理する貯蔵用の貯留部を備えるが、従来、上記乾燥用や貯蔵用の各貯留部の貯留空間を、夫々別個の部材を用いて構成して、間隔を離して独立して設置するようにしていた。
【０００３】
【発明が解決しようとする課題】
しかしながら、上記従来技術では、乾燥用や貯蔵用の貯留部の各貯留空間が夫々別体で分離した状態で設置されるので、各貯留空間を形成する壁部分を各貯留部毎に構成する必要があり、そのため、貯留部の数が増えるのに比例して、材料費が増大するとともに、組み立て作業の手間も増えて、設備の製作費用が増大し、且つ、設置スペースも広くなるという不具合があった。
【０００４】
本発明は、かかる実情に鑑みてなされたものであり、その目的は、上記従来技術の不具合を解消すべく、乾燥用の貯留部と貯蔵用の貯留部とを備える穀物乾燥貯留設備の製作費用を極力低減させると共に、極力狭い設置スペースで済むようにすることにある。
【０００５】
【課題を解決するための手段】
請求項１によれば、穀物を乾燥処理する乾燥用の貯留部と、穀物を貯蔵処理する貯蔵用の貯留部とが、その各貯留空間を形成する壁部分を共用する状態で、隣接して設けられ、その各貯留空間が、主柱と梁を組み付けるとともに、前記主柱同士の間の中央において、上下の前記梁に対して間柱を組み付けて、左右方向に並ぶ前記主柱と前記間柱、及び、上下の前記梁によって矩形状のパネル組み付け用の枠部分を上下方向に複数個形成し、前記各枠部分に対して、前記枠部分を形成する前記主柱、前記間柱及び前記梁に対して同一サイズのパネルを組み付ける状態で形成されて、穀物を乾燥して貯留する穀物乾燥貯留設備が構成される。
従って、穀物乾燥用の貯留部の貯留空間を形成する壁部分と、穀物貯蔵用の貯留部の貯留空間を形成する壁部分とが共用されているので、従来のように、乾燥用及び貯蔵用の各貯留部を夫々別個の部材で構成して間隔を離して独立して設置するものでは、各貯留空間を形成する壁部分を各貯留部毎に設ける必要があり、貯留部の数が増えるのに比例して、材料費が増大し、且つ、組み立て作業の手間も増えるのに比べて、共用する壁部分について製作費が節約でき且つ組み立ての手間も少なくなり、設備の製作費用の低減が実現でき、同時に、設備の設置スペースも極力狭くすることができる。
【０００６】
請求項２によれば、請求項１において、乾燥用の貯留部の複数が、乾燥用の貯留部と貯蔵用の貯留部とが隣接して並ぶ並び方向と交差する方向に隣接して設けられて、その隣接する乾燥用の貯留部の間の前記壁部分が共用され、貯蔵用の貯留部の複数が、前記並び方向と交差する方向に隣接して設けられて、その隣接する貯蔵用の貯留部の間の前記壁部分が共用され、複数の乾燥用の貯留部及び複数の貯蔵用の貯留部のうちで、前記並び方向に隣接する各乾燥用の貯留部と各貯蔵用の貯留部との間の前記壁部分が共用されている。
従って、乾燥用の貯留部と貯蔵用の貯留部を夫々複数設置する場合に、各貯留部の壁部分が極力共用するように隣接して配置するので、設備の設置スペースが少なくて済むとともに、より一層の設備費用の低減を実現することができ、もって、請求項１の好適な手段が得られる。
【０００７】
請求項３によれば、請求項１又は２において、前記共用される壁部分が、壁厚さ方向に間隔を隔てて位置して、一対の平坦面状の壁表面部を形成する一対の矩形状の板状部と、壁厚さ方向での強度を補強すべく、それら一対の板状部の間の内部空間内に位置して、一対の板状部を接続する補強部とを備えたパネルにて構成されている。
従って、各貯留空間の内方側から壁厚さ方向にかかる圧力を、壁部分を構成するパネルに備えた一対の板状部とそれら一対の板状部を接続する補強部とで支えるので、壁厚さ方向での強度を確保しながら、壁部分を単板にて構成する場合に比べて、各板状部の厚みを合わせた厚みを薄くすることができて、壁部分の重量を極力軽くすることができる。そして、このような重量が軽い壁部分に形成したことにより、施工の際の作業者の労力を軽減でき、又、壁部分を支持する柱や梁の強度を下げることができて、各貯留空間を形成するための材料費を低減して、穀物乾燥貯留設備の製作コストを低減することができる。
更に、平坦面状の壁表面部が各貯留空間に面することになるので、例えば波状の壁表面部の場合のようにデッドスペースが生じることなく、各貯留空間内を穀物が良好に流動するように形成することができ、もって、請求項１又は２の好適な手段が得られる。
【０００８】
請求項４によれば、請求項１〜３のいずれか１項において、貯蔵用の貯留部の両側に、乾燥用の貯留部が設けられるので、大容量化のために大型になりやすい貯蔵用の貯留部を中央にして両側に乾燥用の貯留部をバランス良く配置させることができ、もって、請求項１〜３のいずれか１項の好適な手段が得られる。
【０００９】
請求項５によれば、請求項１〜４のいずれか１項において、貯蔵用の貯留部及び乾燥用の貯留部の各貯留空間の夫々を覆う覆いが設けられているので、例えば、貯蔵用の貯留部と乾燥用の貯留部の全てを収める建屋を建設する必要がなく、そのような建屋を建設する場合に比べて設備全体として大幅な製作費用の低減が実現でき、もって、請求項１〜４のいずれか１項の好適な手段が得られる。
【００１０】
【発明の実施の形態】
以下、本発明に係る穀物乾燥貯留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、穀物処理設備が、納入者が投入する穀物の荷受け処理を行う荷受け部Ａ、穀物を貯留するとともに乾燥処理する乾燥用の貯留部としての貯留ビンＤ、乾燥後の穀物を貯蔵処理する貯蔵用の貯留部としてのサイロＳ、穀物の籾摺調整を行う籾摺調整部Ｅ及び出荷処理を行う出荷部Ｆ等を備えて構成されている。ここで、貯留ビンＤとサイロＳが、穀物を乾燥して貯留する穀物貯留乾燥設備を構成する。
【００１１】
荷受け部Ａは、穀物を受け入れる荷受けホッパー２１、荷受けホッパー２１からの穀物を横送りする荷受けコンベア２２、穀物を揚送する第１揚送コンベア２３、穀物を一旦貯留する流量調整タンク２４、穀物から藁屑等の異物を除去するための粗選機２５、精選処理時には粗選機２５から排出される穀物を精選別する精選機２６、荷受け処理時には粗選機２５から排出される穀物を計量し、精選処理時には精選機２６から排出される穀物を計量する荷受け用計量機２７、粗選機２５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２８、精選機２６から排出される脱ぷ米を貯留する脱ぷ米タンク２９等を備えている。
又、籾摺調整部Ｅには、調整タンク６１、籾摺調整装置６２、石抜機６３等が備えられ、出荷部Ｆには、計量タンク６４、出庫用計量機６５、自動給袋機６６等が備えられている。
【００１２】
荷受け時において、荷受け用計量機２７から排出される計量後の穀物は、第２揚送コンベア６７によって揚送され、供給用コンベア６８によっていずれかの貯留ビンＤに貯留されることになる。貯留ビンＤに貯留されて乾燥処理された穀物は、各下端部の排出部６９から後述のように送風によって排出されて横送りコンベア７０によって搬送され、第３揚送コンベア７１により揚送搬送されて、第４揚送コンベア７２及び供給コンベア７３によりいずれかのサイロＳへ供給されることになる。
そして、サイロＳに供給されている穀物は、下方の排出口７４から横送りコンベア７５によって横送りされ、第４揚送コンベア３０によって揚送された後、精選処理時には、荷受け部Ａの第１揚送コンベア２３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Ｅに供給され更に出荷部Ｆを通して出荷されるようになっている。ちなみに、貯留ビンＤは、サイロＳが満杯のときなどにおいては、サイロとしても用いられるものであって、上記サイロＳと同様に、荷受け部Ａの第１揚送コンベア２３や籾摺調整部Ｅに向けて、貯留穀物を搬送できるように構成されている。
【００１３】
尚、上記荷受け部Ａにおける流量調整タンク２４、粗選機２５、精選機２６、荷受け用計量機２７、脱芒機２８、脱ぷ米タンク２９等は、それらの各装置を穀物が上方から下方に向けて流下するように上下方向に積み重ねて一体的に固定した段積み構成として、設置スペースを少なくするようにしてある。
【００１４】
図２〜図４に示すように、穀物を乾燥処理する乾燥用貯留空間を備えた貯留ビンＤと、穀物を貯蔵する貯蔵用貯留空間を備えたサイロＳとが、サイロＳの両側に貯留ビンＤが位置する状態で、且つ、夫々平面視で矩形状に形成してある各貯留空間を形成する壁部分Ｗを共用する状態で、隣接して設けられている。
つまり、貯留ビンＤの複数（図ではサイロＳの列の左右に各５個で計１０個）が、貯留ビンＤとサイロＳとが隣接して並ぶ並び方向と交差する方向に隣接して設けられて、その隣接する貯留ビンＤの間の壁部分Ｗが共用され、サイロＳの複数（図では５個）が、上記貯留ビンＤとサイロＳとの並び方向と交差する方向に隣接して設けられて、その隣接するサイロＳの間の壁部分Ｗが共用され、さらに、上記１０個の貯留ビンＤ及び５個のサイロＳのうちで、前記並び方向に隣接する各貯留ビンＤと各サイロＳとの間の壁部分Ｗが共用されている。ここで、共用される壁部分Ｗは、後述のパネルＰにて構成されている。
【００１５】
次に、上記サイロＳと貯留ビンＤの各貯留空間を形成するための構成について説明する。主柱５と梁６を組み付けるとともに、主柱５同士の間の中央において、上下の梁６に対して間柱７を組み付けて、左右方向に並ぶ主柱５と間柱７、及び、上下の梁６によって矩形状のパネル組み付け用の枠部分を形成し、各枠部分に対して、枠部分を形成する主柱５、間柱７及び梁６に対してパネルＰを組み付けて、各貯留空間を形成している。
つまり、枠部分を形成する主柱５、間柱７及び梁６にパネルＰを組み付けた状態では、パネルＰに対しては、上下方向並びに横方向での荷重がほとんどかからず、貯留穀物によるパネル厚さ方向での圧力のみがかかるようにして、後述のように中空状態にして軽量化したパネルＰでも、要求される強度を充分に確保できるようにしてある。
パネルＰは上下方向に複数枚（本実施形態では３枚）を取り付けるが、同一サイズのパネルＰにて各貯留空間の側壁部を形成するように、パネルＰを共通化するとともに、上下方向での位置に応じて、パネル厚さ方向での強度が異なる３種類のパネルＰを用意し、各位置で要求されるパネル厚さ方向での強度に充分耐え得る強度を備えたパネルＰを配置するようにしてある。ちなみに、下方側には強度大のパネルＰを、上方側には強度小のパネルＰを配置する。
以上のようにして、各貯留空間を形成することにより、構造物全体を形成する材料の総重量を軽量化して、コストダウンを図っている。
【００１６】
更に、５個のサイロＳ及び１０個の貯留ビンＤの各貯留空間の夫々を一括して覆う覆い８が、主柱５にて支持する状態で設けられている。
つまり、覆い８を支持する柱を、貯留空間を形成する主柱５にて共用することにより、例えば、５個のサイロＳ及び１０個の貯留ビンＤの全てを収める建屋を建設する場合に比べて、コストダウンが可能になる。
又、図示はしないが、上記貯留ビンＤとサイロＳを集合させた構造物の直線状の外周面を囲むように、断熱材が配置されて断熱施工が行われる。
【００１７】
主柱５と梁６、及び、梁６と間柱７とはネジ式締結手段によって組み付けるように、並びに、パネル組み付け用の枠部分を形成する主柱５、間柱７及び梁６夫々とパネルＰとはネジ式締結手段によって組み付けるように構成してある。
【００１８】
次に、図５〜図７に基づいて、主柱５と梁６、及び、梁６と間柱７との組み付け構造について説明を加える。
主柱５は角柱状に形成してあり、間柱７及び梁６夫々は横断面形状がＨ形状に形成してある。
梁６において、主柱５に対する組み付け部分である両端部を除いた部分には、予め、Ｈ形状の両側の凹部を蓋するように板状材９を溶接にて取り付けてあり、残りの部分は、後述するように梁６を主柱５に組み付けた後で、蓋部材１０をネジ止めして蓋をするようにしてある。又、同様に、間柱７において、梁６に対する組み付け部分である両端部を除いた部分には、予め、Ｈ形状の両側の凹部を蓋するように板状材９を溶接にて取り付けてあり、残りの部分は、後述するように間柱７を梁６に組み付けた後で、蓋部材１０をネジ止めして蓋をするようにしてある。これは、穀物を貯留したときに、梁６や間柱７の凹部に穀物が溜まるのを防止するためである。
【００１９】
主柱５における梁６の組み付け箇所には、複数のボルト挿通孔を形成した取り付け板１１を突設してあり、梁６の両端部夫々には、取り付け板１１の複数のボルト挿通孔に対応させて複数のボルト挿通孔を形成してある。そして、取り付け板１１のボルト挿通孔と梁６のボルト挿通孔とにボルト１２を挿通してナット１３を締め付けることにより、主柱５と梁６とを組み付ける。
【００２０】
梁６における間柱７の組み付け箇所には、複数のボルト挿通孔を形成した取り付け板１１を突設してあり、間柱７の両端部夫々には、取り付け板１１の複数のボルト挿通孔に対応させて複数のボルト挿通孔を形成してある。そして、取り付け板１１のボルト挿通孔と間柱７のボルト挿通孔とにボルト１２を挿通してナット１３を締め付けることにより、梁６と間柱７とを組み付ける。
【００２１】
次に、枠部分を形成する主柱５、間柱７及び梁６に対するパネルＰの取り付け構造を説明する。
左右方向に並ぶ主柱５、間柱７、上下の梁６夫々の枠内面に対応する部分には、枠全周にわたるように取り付け板１４を溶接接続する。取り付け板１４には、枠内外方向（パネル幅方向に相当する）を向く複数のネジ孔１４ｈを周方向に沿って間隔を隔てて形成してある。
尚、取り付け板１４にて形成される枠内周の大きさは、パネルＰの外周つまり額縁材４の外周よりもやや大きくなるように構成してある。
【００２２】
そして、外形形状がパネルＰの額縁材４と同一形状に形成した取り付け枠１５を、取り付け板１４にて形成される枠内に配置する。
取り付け枠１５と取り付け板１４との間の隙間には、シム１６を挿入してその隙間を塞ぐ。
取り付け枠１５には、枠内外方向（パネル幅方向に相当する）を向く複数の長孔１５ｏを取り付け板１４の複数のネジ孔１４ｈに対応させて形成するとともに、枠厚さ方向（パネル厚さ方向に相当する）に向く複数のボルト挿通孔１５ｈを額縁材４の複数のボルト挿通孔４ｈに対応させて形成してある。
そして、ボルト１７を取り付け枠１５の長孔１５ｏに挿通して取り付け板１４のネジ孔１４ｈにねじ込むことにより、取り付け枠１５を主柱５、間柱７及び梁６に対して取り付ける。
【００２３】
続いて、図６に示すように、パネルＰを、取り付け枠１５がパネル全周部の端面における額縁材４の不存在箇所に嵌まり込むように配置して、ボルト１８を額縁材４のボルト挿通孔４ｈ及び取り付け枠１５のボルト挿通孔１５ｈに挿通してナット１９を締め付けることにより、パネルＰを主柱５、間柱７及び梁６に対して組み付ける。
又、梁６におけるパネル厚さ方向の幅はパネルＰの厚さよりも大きいので、パネルＰとその下方側の梁６とにより形成される角部に穀物が溜まらないように、覆い板２０をビス止めするようにしてある。
【００２４】
上記のようなパネルＰの組み付け構造を採用することにより、以下に説明するような利点がある。
つまり、パネルＰの額縁材４、取り付け枠１５、主柱５、間柱７及び梁６等の各部材は、工場にて製作するので寸法精度が高いが、主柱５、間柱７及び梁６の組み付けは現場で行うので、主柱５、間柱７及び梁６にて形成されるパネル取り付け用の枠部分については寸法精度が低下する。
そこで、主柱５、間柱７、上下の梁６にて形成される枠部分に対して、枠内周の大きさがパネルＰの額縁材４の外周よりもやや大きくなるように、取り付け板１４を枠状に取り付け、その取り付け板１４に対して、額縁材４と同一形状の取り付け枠１５を、パネル幅方向に締め付けるネジ式締結手段（ボルト１７とネジ孔１４ｈ）によってシム１６を介して取り付け、その取り付け枠１５に対してパネルＰを額縁材４を用いて取り付けるようにしてある。
従って、主柱５、間柱７及び梁６にて形成されるパネル取り付け用の枠部分の寸法がばらついても、パネルＰを確実に取り付けることができる。
【００２５】
次に、図８〜図１２に基づいて、パネルＰについて説明する。
パネルＰは、パネル厚さ方向（壁部分Ｗの壁厚さ方向）に間隔を隔てて位置して、一対の平坦面状のパネル表面部（壁部分Ｗの壁表面部）を形成する一対の矩形状の板状部Ｂと、パネル厚さ方向での強度を補強すべく、それら一対の板状部Ｂの間の内部空間内に位置して、一対の板状部Ｂを接続する補強部Ｒとを備えて構成してある。更に、パネル全周部の端面に、額縁材４を設けてある。
【００２６】
一対の板状部Ｂの一部分を形成するための板状部形成用の板部Ｔｂ及び補強部Ｒの一部分を形成するための補強部形成用の板部Ｔｒとを備えるように、横断面形状が矩形状に形成された角筒状体Ｔの複数を、隣り合う角筒状体Ｔの補強部形成用の板部Ｔｒ同士を接続した状態で、パネル幅方向に並設し、並設した複数の角筒状体Ｔにおける、一対の板状部形成用の板部Ｔｂにて一対の板状部Ｂを、且つ、補強部形成用の板部Ｔｒにて補強部Ｒを構成してある。
更に、角筒状体Ｔの内部に、一対の板状部形成用の板部Ｔｂ同士を接続する補強材Ｔｃを設けてあり、その補強材Ｔｃも補強部Ｒを構成するようにしてある。
【００２７】
角筒状体Ｔについて、説明を加える。
板状材を、長方形状の平板部１ａと、その平板部１ａの両端からその平板部１ａに垂直な方向に延びる屈曲部１ｂと、屈曲部１ｂ夫々の端部から平板部１ａと平行に内方側に突出した鍔部１ｃを備えるように成形して、横断面形状が略Ｃ型のＣ形材１を形成する。
平板部２ａとその平板部２ａの一端からその平板部２ａに垂直な方向に延びる屈曲部２ｂを備えた横断面形状が略Ｌ形で長尺状のＬ形材２の２本を、夫々の長手方向をＣ形材１の幅方向（屈曲部１ｂを形成した端縁に直交する方向）に向けて、Ｃ形材１における屈曲部１ｂの側の面に、Ｃ形材１を長手方向（屈曲部１ｂを形成した端縁の延びる方向）に略等間隔に３分割する位置に配置して、溶接接続してある。
Ｃ形材１にＬ形材２を溶接した状態では、Ｌ形材２の屈曲部２ｂの外方側の面がＣ形材１の鍔部１ｃの外方側の面と略同一面を形成するとともに、Ｌ形材２の屈曲部２ｂがＣ形材１の両側の鍔部１ｃ間の略全長にわたる状態となるようにしてある。更に、Ｃ形材１における屈曲部１ｂが存在しない両端には、端部を蓋するように板状材３を溶接接続してある。
【００２８】
そして、一対のＣ形材１を、夫々の鍔部１ｃ同士、Ｌ形材２の屈曲部２ｂ同士、及び、板状材３の端縁同士を夫々を当付けた状態で対向させて、一対のＣ形材１夫々の屈曲部１ｂ同士、及び、一対の板状材３同士を溶接接続して、横断面形状が矩形状の角筒状体Ｔを形成してある。
つまり、Ｃ形材１の平板部１ａを板状部形成用の板部Ｔｂとして、一対のＣ形材１夫々の屈曲部１ｂ同士を接続した状態のものを、補強部形成用の板部Ｔｒとして、一対のＣ形材１夫々に接続したＬ形材２同士が互いに接当した状態のものを補強材Ｔｃとして、夫々機能させるようにしてある。
【００２９】
そして、３個の角筒状体Ｔを、互いに補強部形成用の板部Ｔｒを接当させた状態でパネル幅方向に密接状態に並べ、隣合う角筒状体Ｔの補強部形成用の板部Ｔｒ同士を溶接接続してある。
つまり、並設した３個の角筒状体Ｔにおける、一対の板状部形成用の板部Ｔｂにて一対の板状部Ｂを構成してある。又、並設した３個の角筒状体Ｔにおける、補強部形成用の板部Ｔｒ、角筒状体Ｔの内部の補強材Ｔｃ、及び、板状材３にて、補強部Ｒを構成してある。
従って、パネル厚さ方向視において、補強材Ｔｃ及び板状材３夫々と補強部形成用の板部Ｔｒとは互いに直交する状態となる。つまり、補強部Ｒは、パネル厚さ方向視にてパネルの縦横の幅方向に沿う縦方向補強部と横方向補強部とを備えるように形成してある。
【００３０】
しかも、縦方向補強部に相当する補強材Ｔｃ及び板状材３を略等間隔で並設し、並びに、横方向補強部に相当する補強部形成用の板部Ｔｒを略等間隔で並設してあり、そのことによって、補強部Ｒを、パネル幅方向の全体において同じ強度になるように補強するように構成してある。
そして、筒壁の厚み（具体的には、Ｃ形材１の厚み）の異なる角筒状体Ｔを用いることにより、板状部Ｂの厚みが異なることによってパネル厚さ方向での強度が異なる２種類のパネルＰを製作するようにしてある。
【００３１】
尚、角筒状体Ｔは、横断面形状が偏平長方形状となる偏平状に形成してあり、そのような偏平状の角筒状体Ｔを用いることにより、パネルＰを形成するための角筒状体Ｔの個数を少なくして、コストダウンを図っている。
【００３２】
額縁材４について、説明を加える。
額縁材４は、横断面形状が略正方形状の角筒材を用いて、並設した３個の角筒状体Ｔが内部に嵌め込み可能な形状の矩形枠状に形成してある。更に、額縁材４には、組み付け用として、パネル厚さ方向を向く複数のボルト挿通孔４ｈを周方向に沿って間隔を隔てて形成してある。
額縁材４は、パネル厚さ方向での幅がパネルＰの厚さの略半分になるように形成してある。そして、パネルＰの一方のパネル表面部と額縁材４の表面部とが面一状になるように、額縁材４にパネルＰを嵌め込んで、額縁材４とパネルＰとを溶接接続してある。つまり、額縁材４を、パネル全周部の端面におけるパネル厚さ方向での一端側に偏らせて設けてある。
【００３３】
次に各貯留ビンＤの構成について説明する。
図１５に示すように、並列配置される５個の各貯留ビンＤに対して多孔状で通気可能な床部３１の下方側から導入して貯留ビンＤの上部から排出するように通風させる送風機３２を設け、５個の貯留ビンＤ夫々の上部に対して排気作用する排風機３３を設けている。そして、各貯留ビンＤの上部側の穀物投入口３４には投入用シャッター３５を設け、下部の穀物の排出部６９にはそれを開閉する排出用シャッター３６を設けてある。
送風機３２は５個の貯留ビンＤ夫々に対して設け、送風機３２による通流空気を貯留ビンＤの床部３１に導入する状態と、５個全部の送風機３２による通流空気を合流して、５個の貯留ビンＤのうちから選択自在な１つの貯留ビンＤの下方側に導入する状態とに切り換え自在に構成されている。
【００３４】
詳述すると、図１４に示すように、貯留ビンＤの床部３１と下方側の底部３７との間を隔壁３８により上下二つに仕切り、隔壁３８と底部３７との間を、隔壁３９，４０により貯留ビンＤの並設方向と直交する方向に３つに仕切ってある。貯留ビンＤ内において床部３１と隔壁３８とによって仕切られる空間と、隔壁３８の下方に隔壁３９，４０によって仕切られる空間とは、連通口４１によって互いに連通させてあり、これら互いに連通する二つの空間によって、送風機３２からの空気を床部３１の下方側から貯留空間に導入するための導風路４２を形成している。
隔壁３８、隔壁３９、貯留ビンＤの下部前壁５７及び底部３７にて仕切られる仕切空間に臨む部分には、送風機３２の連通口を形成し、前記仕切空間を５個の貯留ビンＤにわたって一連に連通させて連通風路４４を形成してある。又、貯留ビンＤの隣接するもの同士で共有する壁部における前記連通風路４４を形成するための開口には、開閉操作される合流制御用ダンパ４５を設け、各貯留ビンＤの隔壁３９に形成した連通口には各貯留ビンＤの導風路４２と連通風路４４とを連通する状態と遮断する状態とに切り換えるための通風制御用ダンパ４６を設けてある。尚、送風機３２夫々の吸い込み口付近には、吸い込み口に吸い込まれる空気を加熱するヒータ４３を設けている。
【００３５】
隔壁３８、隔壁４０、貯留ビンＤの下部後壁５８及び底部３７にて仕切られる空間を、５個の貯留ビンＤにわたって一連に連通させて、そのように連通した通路内に排出用の横送りコンベア７０を配置してある。
【００３６】
そして、図１４に示すように、貯留ビンＤにおける穀物貯留空間の床部３１は、金属板を打ち抜いて多数の通気孔３１ａを形成するとともに、打ち抜きの際に舌片３１ｂが排出部６９側に延びる状態で形成されるようにして、下方側から供給される空気を上方側に通過させるとともに、排出部６９側に変向するように構成している。
【００３７】
前記各貯留ビンＤの内部の穀物貯留空間には、穀物を上下方向に移動しながら攪拌する攪拌装置Ｍを設けてある。
攪拌装置Ｍは、貯留ビンＤの上部に平行状態で設けた一対のネジ軸４７と、そのネジ軸４７に夫々噛合する一対のコマ部材４８と、それら一対のコマ部材４８に連結した軸体４９と、その軸体４９を往復移動させるべくネジ軸４７を夫々回動させる一対の移動用電動モータ５０と、軸体４９に出力軸を下方に向けて取付けた一対の回転用電動モータ５１と、回転用電動モータ５１夫々の出力軸に連結した一対の螺旋体５２とを備えて構成し、回転用電動モータ５１夫々を駆動させて螺旋体５２夫々を回転させながら、移動用電動モータ５０を正逆方向に交互に駆動させて、軸体４９を往復移動させることにより、貯留空間の略全域にわたって貯留されている穀物を上下方向に攪拌移動させるように構成してある。
【００３８】

D is adjacently provided in a state where D is located, and in a state where wall portions W forming each storage space formed in a rectangular shape in plan view are shared.
That is, a plurality of storage bins D (a total of 10 in each of the five silos S on the left and right sides in the figure) are provided adjacent to each other in a direction intersecting the direction in which the storage bins D and the silos S are adjacently arranged. Then, the wall portion W between the adjacent storage bins D is shared, and a plurality of silos S (five in the figure) are adjacent to each other in a direction intersecting the direction in which the storage bins D and the silos S are arranged. Provided, the wall portion W between the adjacent silos S is shared, and among the ten storage bins D and the five silos S, each of the storage bins D adjacent to the row direction and The wall portion W between the silo S and the silo S is shared. Here, the shared wall portion W is constituted by a panel P described later.
[0015]
Next, a configuration for forming each storage space of the silo S and the storage bin D will be described. In addition to assembling the main columns 5 and the beams 6, the studs 7 are assembled to the upper and lower beams 6 at the center between the main columns 5, and the main columns 5 and the studs 7 arranged in the left-right direction and the upper and lower beams 6 are arranged. To form a frame portion for assembling a rectangular panel, and for each frame portion, assembling the panel P to the main pillars 5, studs 7 and beams 6 forming the frame portion to form each storage space. ing.
That is, in a state where the panel P is assembled to the main pillar 5, the studs 7 and the beams 6 forming the frame portion, the load is hardly applied to the panel P in the vertical direction and the horizontal direction, and the panel made of the stored grain is not applied. Only the pressure in the thickness direction is applied so that the required strength can be sufficiently ensured even in the panel P which is made hollow and light as described later.

It is like that. Incidentally, a panel P with high strength is arranged on the lower side, and a panel P with low strength is arranged on the upper side.
By forming each storage space as described above, the total weight of the material forming the entire structure is reduced, and the cost is reduced.
[0016]
Further, a cover 8 that collectively covers each of the storage spaces of the five silos S and the ten storage bins D is provided so as to be supported by the main pillar 5.
In other words, by sharing the pillar supporting the cover 8 with the main pillar 5 forming the storage space, for example, as compared with a case where a building that accommodates all the five silos S and the ten storage bins D is constructed. Cost can be reduced.
Although not shown, a heat insulating material is disposed so as to surround the linear outer peripheral surface of the structure in which the storage bin D and the silo S are assembled, and heat insulation is performed.
[0017]
The main pillar 5, the stud 7, the beam 6, and the panel P are formed so that the main pillar 5 and the beam 6, and the beam 6 and the stud 7 are assembled by screw-type fastening means, and each of the main pillar 5, the stud 7, and the beam 6 forming a frame portion for panel assembly. Are configured to be assembled by screw-type fastening means.
[0018]
Next, an assembly structure of the main column 5 and the beam 6 and the beam 6 and the stud 7 will be described with reference to FIGS.
The main pillar 5 is formed in a prismatic shape, and each of the studs 7 and the beams 6 is formed to have an H-shaped cross section.
In the beam 6, a plate-like material 9 is attached in advance to portions except for both end portions which are portions to be assembled to the main column 5 by welding so as to cover concave portions on both sides of the H shape, and the remaining portions are After assembling the beam 6 to the main column 5 as described later, the lid member 10 is screwed and covered. Similarly, in the studs 7, a plate-like material 9 is attached by welding to parts other than both ends which are parts to be attached to the beam 6 so as to cover the concave portions on both sides of the H shape in advance. As for the remaining portion, the stud 7 is attached to the beam 6 as described later, and then the cover member 10 is screwed and covered. This is to prevent grain from accumulating in the recesses of the beams 6 and the studs 7 when the grain is stored.
[0019]
A mounting plate 11 having a plurality of bolt insertion holes is protruded from the main column 5 at the position where the beam 6 is to be assembled. Each end of the beam 6 corresponds to the plurality of bolt insertion holes of the mounting plate 11. Thus, a plurality of bolt insertion holes are formed. Then, the main column 5 and the beam 6 are assembled by inserting the bolt 12 into the bolt insertion hole of the mounting plate 11 and the bolt insertion hole of the beam 6 and tightening the nut 13.
[0020]
A mounting plate 11 having a plurality of bolt insertion holes is protruded from the beam 6 at a location where the stud 7 is assembled, and both ends of the stud 7 are respectively made to correspond to the plurality of bolt insertion holes of the mounting plate 11. A plurality of bolt insertion holes. Then, the beam 6 and the pillar 7 are assembled by inserting the bolt 12 into the bolt insertion hole of the mounting plate 11 and the bolt insertion hole of the pillar 7 and tightening the nut 13.
[0021]
Next, a structure for attaching the panel P to the main pillars 5, the studs 7, and the beams 6 forming the frame portion will be described.
Attachment plates 14 are welded to portions corresponding to the inner surfaces of the main columns 5, studs 7, and upper and lower beams 6, which are arranged in the left-right direction, so as to cover the entire periphery of the frame. The mounting plate 14 is formed with a plurality of screw holes 14h facing in and out of the frame (corresponding to the panel width direction) at intervals along the circumferential direction.
The size of the inner circumference of the frame formed by the mounting plate 14 is configured to be slightly larger than the outer circumference of the panel P, that is, the outer circumference of the frame member 4.
[0022]
Then, the mounting frame 15 having the same outer shape as the frame material 4 of the panel P is arranged in the frame formed by the mounting plate 14.
A shim 16 is inserted into a gap between the mounting frame 15 and the mounting plate 14 to close the gap.
In the mounting frame 15, a plurality of long holes 15o facing the inside and outside of the frame (corresponding to the panel width direction) are formed corresponding to the plurality of screw holes 14h of the mounting plate 14, and in the frame thickness direction (panel thickness). (Corresponding to the direction) are formed so as to correspond to the plurality of bolt insertion holes 4h of the frame member 4.
Then, the bolt 17 is inserted into the long hole 15 o of the mounting frame 15 and screwed into the screw hole 14 h of the mounting plate 14, thereby mounting the mounting frame 15 to the main column 5, the stud 7, and the beam 6.
[0023]
Subsequently, as shown in FIG. 6, the panel P is arranged so that the mounting frame 15 fits into the non-existent portion of the frame material 4 on the end face of the entire periphery of the panel, and the bolt 18 is bolted to the frame material 4. The panel P is assembled to the main pillar 5, the studs 7, and the beam 6 by inserting the bolt 19 into the insertion hole 4 h and the bolt insertion hole 15 h of the mounting frame 15 and tightening the nut 19.
Further, since the width of the beam 6 in the panel thickness direction is larger than the thickness of the panel P, the cover plate 20 is screwed so that grain does not accumulate in the corner formed by the panel P and the beam 6 below the panel P. I try to stop it.
[0024]
Adopting the structure for mounting the panel P as described above has advantages as described below.
In other words, the frame member 4, the mounting frame 15, the main pillar 5, the studs 7 and the beams 6 of the panel P are manufactured at the factory and thus have high dimensional accuracy. Since the assembling is performed on site, the dimensional accuracy of the frame portion for panel attachment formed by the main pillar 5, the stud 7 and the beam 6 is reduced.
Therefore, the mounting plate 14 for the frame portion formed by the main pillar 5, the studs 7, and the upper and lower beams 6 is formed such that the inner circumference of the frame is slightly larger than the outer circumference of the frame member 4 of the panel P. Is attached in a frame shape, and an attachment frame 15 having the same shape as the frame material 4 is attached to the attachment plate 14 via a shim 16 by screw-type fastening means (bolts 17 and screw holes 14h) for fastening in the panel width direction. The panel P is attached to the attachment frame 15 using the frame material 4.
Therefore, even if the dimensions of the panel mounting frame formed by the main pillar 5, the studs 7, and the beams 6 vary, the panel P can be securely mounted.
[0025]
Next, the panel P will be described with reference to FIGS.
The panel P is located at an interval in the panel thickness direction (the wall thickness direction of the wall portion W) to form a pair of flat surface panel surface portions (the wall surface portion of the wall portion W). A rectangular plate-shaped portion B and a reinforcing portion which is located in an internal space between the pair of plate-shaped portions B and connects the pair of plate-shaped portions B in order to reinforce strength in a panel thickness direction. R. Further, a frame member 4 is provided on an end face of the entire periphery of the panel.
[0026]
The cross-sectional shape includes a plate portion Tb for forming a plate portion for forming a part of the pair of plate portions B and a plate portion Tr for forming a reinforcement portion for forming a portion of the reinforcement portion R. Are arranged side by side in the panel width direction, with a plurality of rectangular tubular bodies T formed in a rectangular shape being connected to the plate portions Tr for forming the reinforcing portions of the adjacent rectangular tubular bodies T. In the plurality of square tubular bodies T, a pair of plate portions B is formed by a pair of plate portions Tb for forming plate portions, and a reinforcing portion R is formed by a plate portion Tr for forming a reinforcing portion. .
Further, a reinforcing member Tc for connecting a pair of plate portions Tb for forming a pair of plate portions is provided inside the rectangular tubular body T, and the reinforcing member Tc also constitutes a reinforcing portion R.
[0027]
The rectangular tubular body T will be described.
The plate-like material is formed by bending a rectangular flat plate portion 1a, bent portions 1b extending from both ends of the flat plate portion 1a in a direction perpendicular to the flat plate portion 1a, and parallel to the flat plate portion 1a from respective ends of the bent portions 1b. A C-shaped member 1 having a substantially C-shaped cross-section is formed by forming a flange portion 1c protruding toward one side.
Each of two long L-shaped members 2 each having a substantially L-shaped cross section and a flat portion 2a and a bent portion 2b extending from one end of the flat portion 2a in a direction perpendicular to the flat portion 2a is provided. The longitudinal direction is directed to the width direction of the C-shaped member 1 (the direction orthogonal to the edge where the bent portion 1b is formed), and the C-shaped member 1 is placed in the longitudinal direction ( (In the direction in which the edge at which the bent portion 1b is formed extends) at approximately equal intervals into three parts, and are connected by welding.
When the L-shaped member 2 is welded to the C-shaped member 1, the outer surface of the bent portion 2b of the L-shaped member 2 forms substantially the same surface as the outer surface of the flange portion 1c of the C-shaped member 1. At the same time, the bent portion 2b of the L-shaped member 2 extends over substantially the entire length between the flange portions 1c on both sides of the C-shaped member 1. Further, plate-shaped members 3 are welded to both ends of the C-shaped member 1 where the bent portions 1b are not present so as to cover the ends.
[0028]
Then, the pair of C-shaped members 1 are opposed to each other with the respective flange portions 1c, the bent portions 2b of the L-shaped member 2 and the edges of the plate-shaped member 3 abutting each other. The bent portions 1b of each of the C-shaped members 1 and the pair of plate members 3 are connected by welding to form a rectangular tubular body T having a rectangular cross section.
In other words, the flat portion 1a of the C-shaped member 1 is used as a plate portion Tb for forming a plate-shaped portion, and the bent portion 1b of each of the pair of C-shaped members 1 is connected to a plate portion Tr for forming a reinforcing portion. In a state where the L-shaped members 2 connected to the pair of C-shaped members 1 are in contact with each other, the L-shaped members 2 are made to function as reinforcing members Tc.
[0029]
Then, the three rectangular tubular bodies T are arranged closely in the panel width direction in a state in which the plate portions Tr for forming the reinforcing sections are in contact with each other, and the three rectangular tubular bodies T for forming the reinforcing sections of the adjacent rectangular tubular bodies T are arranged. The plate portions Tr are connected by welding.
That is, a pair of plate-shaped portions B is formed by a pair of plate-shaped portion-forming plate portions Tb of the three rectangular tube-shaped members T arranged side by side. In addition, a reinforcing portion R is composed of a plate portion Tr for forming a reinforcing portion, a reinforcing material Tc inside the rectangular tubular member T, and a plate material 3 in the three rectangular tubular members T arranged in parallel. I have.
Therefore, when viewed in the panel thickness direction, each of the reinforcing member Tc and the plate-shaped member 3 and the plate portion Tr for forming the reinforcing portion are orthogonal to each other. That is, the reinforcing portion R is formed so as to include a vertical reinforcing portion and a horizontal reinforcing portion along the width direction of the panel as viewed in the panel thickness direction.
[0030]
Moreover, the reinforcing members Tc and the plate members 3 corresponding to the vertical reinforcing portions are arranged side by side at substantially equal intervals, and the plate portions Tr for forming the reinforcing portions corresponding to the horizontal reinforcing portions are arranged side by side at substantially equal intervals. Thus, the reinforcing portion R is configured to be reinforced so as to have the same strength in the entire panel width direction.
Then, by using the rectangular cylindrical bodies T having different thicknesses of the cylindrical walls (specifically, the thickness of the C-shaped member 1), the strength in the panel thickness direction is different due to the different thickness of the plate-shaped portion B. Two types of panels P are manufactured.
[0031]
The rectangular tubular body T is formed in a flat shape having a flat rectangular cross-sectional shape, and by using such a flat rectangular tubular body T, a square for forming the panel P is formed. The cost is reduced by reducing the number of the tubular bodies T.
[0032]
The frame material 4 will be described.
The frame member 4 is formed of a rectangular tube member having a substantially square cross-sectional shape, and is formed into a rectangular frame shape having a shape in which three juxtaposed rectangular tube members T can be fitted inside. Further, the frame member 4 is formed with a plurality of bolt insertion holes 4h oriented in the panel thickness direction at intervals along the circumferential direction for assembly.
The frame member 4 is formed such that the width in the panel thickness direction is approximately half the thickness of the panel P. Then, the panel P is fitted into the frame member 4 so that one panel surface portion of the panel P and the surface portion of the frame member 4 are flush with each other, and the frame member 4 and the panel P are connected by welding. is there. That is, the frame member 4 is provided so as to be biased toward one end side in the panel thickness direction on the end surface of the entire peripheral portion of the panel.
[0033]
Next, the configuration of each storage bin D will be described.
As shown in FIG. 15, a blower that introduces air into each of five storage bins D arranged in parallel from below the porous and permeable floor portion 31 and discharges the storage bins D from the upper portion thereof. 32, and an exhaust fan 33 that exhausts air to the upper part of each of the five storage bins D is provided. The grain input port 34 on the upper side of each storage bin D is provided with a charging shutter 35, and the lower grain discharging section 69 is provided with a discharging shutter 36 for opening and closing it.
