【０００１】
【発明の属する技術分野】
本発明は、例えば米・麦・大豆などの穀物を乾燥させる機能などを備えた穀物貯蔵タンクの穀物排出装置に関する。
【０００２】
【従来の技術】
従来、床を通気構造とし、床面から乾燥空気を送込んで貯蔵穀物を乾燥させる円筒形状の穀物貯蔵タンクでは、実公昭５６−４０７６２号公報、実開昭５７−１４７８４２号公報、特公平３−３７９７８号公報に示されるように、床中心部に穀物排出口が開設され、且つ、床面に半径方向にスクリューコンベアが横架されており、該スクリューコンベアが排出口を中心に床面上を旋回しながら排出口に向って穀物を移送することにより、タンクの残留穀物を機械的に排出していた。また、穀物排出口側を公転中心として穀槽の内周近傍まで延びる穀物排出オーガーを設け、公転先端部に遊動走行輪を備えた螺旋軸に集穀板を並設させ、該集穀板にブラシ状のスクレーパを装着したものが特開平８−８５６３０号公報に記載され、実開昭５９−４９６８３号公報には、タンク内に回転自在に支持された中心軸部材と、これに直交する水平部材からなるレーキを配設し、該水平部材に取付けたブレードをタンク底と水平部材の間隔に設け、沈降堆積物や液体を中心開口部に押しやるように前記ブレードを傾けた構成が開示されている。
【０００３】
【発明が解決しようとする課題】
前記従来技術は、タンク床面とスクリューコンベアのスパイラルとの間に隙間ができ、該隙間の残留穀物は機械的に排出できず、人手による排出作業を強られていた。そこで本発明は、前記隙間の残留穀物も機械的に排出できる穀物排出装置を提供することを主たる目的としている。
【０００４】
【課題を解決するための手段】
然るに、本発明は、中心部に穀物排出口を設けた円形状のタンク床を有する穀物貯蔵タンクの穀物排出装置において、内端が旋回軸に枢着され、且つ、外端を転輪に枢着してタンク床面の半径方向に横架し、穀物排出口を中心にタンク床面上を旋回しながら穀物に穀物排出口への送りを与えるスクリューコンベアであって、先端をタンク床面に接触させて穀物を穀物排出口方向へはき寄せるブラシ体を備え、該ブラシ体をスクリューコンベアの後方でスパイラル軸方向に横一列に並設し、且つ、前端が後端より外側を通過するリード角を付けたスクレーパブラシの構成にし、スクリューコンベアの後方を追従旋回するスクレーパ取付板に前記スクレーパブラシを調節自在に取付けたことによってスクリューコンベアの送り作用が及ばないその下側の穀物も機械的に排出する。また貯蔵タンクが穀物乾燥用で床が通気構造の場合、ブラシ体は床の通気孔のササリ粒も掻出して排出できると同時に目詰りを防止して通気性を確保し、乾燥機能の低下も防止できる。さらにブラシ体は適当なたわみにより適当に穀物の抜けを生じさせて異状負荷がかかるのを防止したり、スクレーパブラシのリード角を残留穀物の量など作業条件に応じて任意の角度に調節することにより、過負荷状態に至らせることなく作業条件に合った排出能力で穀物の排出を効率良く行うことができる。
【０００５】
さらに、中心部に穀物排出口を設けた円形状のタンク床を有する穀物貯蔵タンクの穀物排出装置において、内端が旋回軸に枢着され、且つ、外端を転輪に枢着してタンク床面の半径方向に横架し、穀物排出口を中心にタンク床面上を旋回しながら穀物に穀物排出口への送りを与えるスクリューコンベアであって、該スクリューコンベアの中空のスパイラル軸内部にバランスウエイトを納め、該ウエイトの増減により転輪の接地圧、つまり転輪の牽引力を残留穀物の量など作業条件に応じて任意に調節することにより、スクリューコンベアを適正速度で回転させ、作業条件に合った排出能力で穀物の排出を効率良く行うことができ、またバランスウエイトを外装したり、予め構成部品の重量を重くしたものに比べ、バランスウエイトがスクリューコンベアの旋回抵抗とならず、外観も損なわせることもない。
【０００６】
【発明の実施の形態】
以下、本発明の実施例を図面に基づいて詳述する。図１は穀物貯蔵タンクの概略を示す断面側面図、図２は同断面平面図であり、図中（１）は米・麦・大豆などの穀物を貯蔵中に通風乾燥する円筒形状の穀物貯蔵タンク、（２）は前記タンク（１）に隣接して設置する揚穀コンベア、（３）は前記揚穀コンベア（２）から受継ぐ穀物をタンク（１）の天井面中央部の投入口（４）からタンク（１）内に投入する投入コンベア、（５）は有孔鉄板で形成する通気構造の円形状のタンク床、（６）は前記床（５）によってタンク（１）上部の穀物貯蔵室（７）と仕切られるタンク（１）底部の乾燥空気風路室、（８）はタンク（１）の外側に設置する乾燥機室、（９）及び（１０）は前記乾燥機室（８）に設置して常温定湿乾燥機を構成する除湿機及び送風機で、前記風路室（６）に送風ダクト（１１）を介して送風機（１０）の排風側を連通接続させ、除湿機（９）から送風機（１０）及びダクト（１１）を介して風路室（６）に送込まれる常温定湿空気を、床（５）の通気孔（５ａ）からこの上方の貯蔵室（７）に供給し、この貯蔵室（７）に貯蔵される籾を一定の含水率まで通風乾燥させるように構成している。
【０００７】
また、図中（１２）はタンク（１）の上部に設ける排気孔である。
【０００８】
上記のように、貯蔵タンク（１）で貯蔵中に通風乾燥された籾は床（５）の中心部に開設された円形状の穀物排出口（１３）から排出されるもので、前記排出口（１３）の下面側にホッパー出口に開閉弁（１４）を有する排出ホッパー（１５）を設けると共に、前記ホッパー（１５）下方に穀物搬出コンベア（１６）を設置し、開閉弁（１４）を開き乾燥籾を排出口（１３）からホッパー（１５）を介して搬出コンベア（１６）上に排出し、搬出コンベア（１６）によってタンク（１）外側に乾燥籾を搬出するように構成している。
【０００９】
また、前記タンク（１）内の乾燥籾は安息角までは自然流下により排出され、その安息角以下の残留籾は機械的に排出するもので、そのためのスイープオーガ型のスクリューコンベア（１７）が前記タンク（１）に設けられている。
【００１０】
前記スクリューコンベア（１７）は、図１乃至図４に示す如く、タンク床（５）面上でこの中心部から半径方向にタンク側壁（１７）内面側の床（５）外縁部までに横架されるもので、中空のスパイラル軸（１８）の外周面に金属製のねじ羽根であるスパイラル（１９）を螺線状に巻付溶着してスクリューコンベア本体を形成している。前記タンク床（５）の中心である排出口（１３）の中心に軸受（２０）を介して旋回軸（２１）を上下方向に立設させ、タンク床（５）面より上方に突出する旋回軸（２１）の上端に電動モータ及び減速ギヤなどを内装する動力ケース（２２）を取付け、動力ケース（２２）の一側面より水平に突出させる出力軸（２３）に軸継手（２４）及びセットピン（２５）を介して前記スパイラル軸（１８）の内端を着脱自在に連動連結すると共に、前記スパイラル軸（１８）の外端に床（５）面に接地させる転輪である駆動車輪（２６）の車軸（２７）をセットピン（２８）を介して連動連結し、出力軸（２３）とスパイラル軸（１８）と車軸（２７）を一直線状に連結させ、これら軸（２３）（１８）（２７）を一体に回転させることにより、前記スクリューコンベア（１７）を回転軸（２１）を中心に床（５）面上を一定の隙間（Ｌ１）を保って一方向に旋回（公転）させながらスパイラル（１９）を回転駆動（自転）させることにより、前記した床（５）前面の残留籾を床（５）中心部の排出口（１３）方向に移送排出させるように構成している。
【００１１】
また、スクリューコンベア（１７）の後方に残留籾を掻取るスイープシールド（２９）を取付けるもので、前記動力ケース（２２）の後面にシールド取付台（３０）を固着すると共に、前記スパイラル軸（１８）外端と車輪（２６）間の車軸（２７）に回転自在に嵌合支持させる軸受部（３１）から後方にシールド取付アーム（３２）を一体延設させ、前記シールド取付台（３０）にスイープシールド（２９）の内端に固着する軸受筒（３３）をセットピン（３４）を介して着脱自在に取付け、前記シールド取付アーム（３２）にスイープシールド（２９）の外端に固着する取付座（３５）をボルトを介して着脱自在に取付け、前記スイープシールド（２９）をスクリューコンベア（１７）の後方でスパイラル軸（１８）と平行に、且つ、床（５）面より若干浮かせて横架させ、スクリューコンベア（１７）の後をスイープシールド（２９）が追従旋回することにより、残留籾を掻取ってスクリューコンベア（１７）側に掻寄せると共に、スクリューコンベア（１７）後方に送り方向の案内壁を作り、残留籾の移送を確実、且つ、円滑に行えるように構成している。
【００１２】
また、図５に示す如く、前記軸継手（２４）と車軸（２７）間のスパイラル軸（１８）の中空内部に円柱形状のバランスウエイト（３６）を納めると共に、スパイラル軸（１８）内端の軸継手（２４）と最も内側のバランスウエイト（３６）間にコイル形状の圧縮バネ（３７）を納め、スパイラル軸（１８）の中空内部にバランスウエイト（３６）をスパイラル軸（１８）外端の車軸（２７）に押付け自由移動を規制した状態で納めるもので、重さの異なる数種類のバランスウエイト（３６）を用意し、車軸（２７）の着脱によってスパイラル軸（１８）の中空内部に納めるバランスウエイト（３６）の総重量を適宜変更することにより、車輪（２６）のタンク床（５）面に対する接地圧を変化、つまりスクリューコンベア（１７）をこの旋回抵抗となる残留籾に抗して旋回させるための車輪（２６）の牽引力を変化させ、残留籾の量など作業条件に応じてスクリューコンベア（１７）の旋回（公転）速度及び自転速度つまり残留籾の移送量（排出能力）を適宜選択可能に構成している。
【００１３】
上記のように、スパイラル軸（１８）の中空内部に納めるバランスウエイト（３６）の増減により、スクリューコンベア（１７）の残留籾の移送量を適宜選択できるようにしたことで、残留籾の量など作業条件に応じたこの残留籾の排出能力が容易に得られ、前記バランスウエイト（３６）を外装したり、予め構成部品の重量を重くして駆動車輪（２６）の牽引力を得る牽引力が調節不可能な構造に比べて繁用性に優れている。またバランスウエイト（３６）がスパイラル軸（１８）の中空内部に納められ、外装品のようにスクリューコンベア（１７）の旋回抵抗を著しく増加させることもなく、さらには外からはバランスウエイト（３６）が見えないため外観も損なうことなく、駆動車輪（２６）の牽引力を得るためのバランスウエイト（３６）を支障なく装備することができる。
【００１４】
前記スクリューコンベア（１７）はスパイラル（１８）の外縁を床（５）面に接触させることができず、そのスパイラル（１８）と床（５）面間の隙間（Ｌ１）の残留籾は排出することができない。
【００１５】
そこで、本実施例では、先端をタンク床（５）面に接触させて隙間（Ｌ１）による残留籾を排出口（１３）方向へはき寄せる第１及び第２のブラシ体を備えている。
【００１６】
図６及び図７は上記した第１のブラシ体を示しており、このブラシ体は、スクリューコンベア（１７）のスパイラル（１９）の外径をタンク床（５）に接触する外径に拡径すべく、断面コ形で一直線状のホルダ（３８）によって毛（３９）の一端がたばねられ、このホルダ（３８）から一方向に毛（３９）が一定長さで立毛する細長い長方形板状のブラシ体のホルダ（３８）底面をスパイラル（１９）外縁に固着してスパイラル外縁より毛（３９）を半径方向に一定の長さで立毛させて形成するスパイラル（１９）外周に取付けたコイルブラシ（４０）であり、このコイルブラシ（４０）の毛長は床（５）面と非接触の自由長がタンク床（５）面とスパイラル（１８）との隙間（Ｌ１）より若干長く形成しており、毛（３９）は自身の可撓性でたわみ状態でタンク床（５）及びスイープシールド（２９）に接触するように形成され、また毛（３９）は床（５）面に接触時に床（５）に傷を付けず、通気孔（５ａ）へのササリ粒を掻出し、且つ、コイルブラシ（４０）面で残留籾を排出口（１３）方向へ移送できるような、ある程度の可撓性と剛性を有する金属または合成樹脂等の材料で作られている。
【００１７】
上記のようにスパイラル（１９）外周にコイルブラシ（４０）を取付け、スパイラル（１９）の外径をタンク床（５）に接触する長さにコイルブラシ（４０）により拡径し、スパイラル（１９）とタンク床（５）間の隙間（Ｌ１）をなくすことによって、従来では機械的に搬出できなかった前記隙間（Ｌ１）の残留籾の排出も機械的に排出することができ、また床（５）面の通気孔（５ａ）のササリ粒もコイルブラシ（４０）は掻出すことができ、穀粒ロスをより少なくできると同時に、床（５）の通気孔（５ａ）の目詰りを防止して通気性を確保するから、タンク（１）の穀物乾燥機能の低下も防止できる。さらにコイルブラシ（４０）は適当なたわみにより適当に籾抜けを生じさせるため、スクリューコンベア（１７）や駆動モータに異状負荷がかかるのも防止できる。またコイルブラシ（４０）はスイープシールド（２９）とスパイラル（１８）との隙間も同時になくすから、この隙間にある籾も確実に移送排出でき、スイープシールド（２９）の前端下部に対するササリ粒も掻出して排出できる。
【００１８】
上記した第１のブラシ体であるコイルブラシ（４０）はスクリューコンベア（１７）の自転を利用して残留籾を排出口（１３）方向へ移送するものであったが、第２のブラシ体はスクリューコンベア（１７）の旋回を利用して残留籾を排出口（１３）方向へ移送するもので、この第２のブラシ体を図３及び図４に示しており、このブラシ体は、断面コ形で直線状のホルダ（４１）によって毛（３９）の一端がたばねられ、このホルダ（４２）から一方向に毛（３９）を一定長さで立毛する長方形板状のほうき形スクレーパブラシ（４３）であり、スイープシールド（２９）の後面からこの後方にタンク床（５）と平行にスクレーパ取付板（４４）を一体延設させ、この取付板（４４）の下面に複数のスクレーパブラシ（４３）のホルダ（４１）をスパイラル軸（１８）方向に等間隔に、且つ、平行に取付け、各スクレーパブラシ（４３）のホルダ（４１）から下向きに立毛する毛（４２）先端を常時床（５）面に接触させた状態でスクリューコンベア（１７）の後方を各スクレーパブラシ（４３）が追従旋回するように設けている。そして、各スクレーパブラシ（４３）は、旋回時にブラシ（４３）前端の旋回軌跡径がブラシ（４３）後端の旋回軌跡径より大径となり、且つ、隣接する内側のスクレーパブラシ（４３）の前端旋回軌跡径が外側のスクレーパブラシ（４３）の後端旋回軌跡径より大径となるリード角（α）を付けてスクレーパ取付板（４４）に取付けられ、また最内側のスクレーパブラシ（４３）はその後端旋回軌跡径がスクリューコンベア（１７）のスパイラル（１８）送り終端の旋回軌跡径と同様に排出口（１３）より小径となる位置に配置されている。さらに各スクレーパブラシ（４３）の毛長は少したわんだ状態で床（５）面に接触する長さで形成され、また毛（４２）は床（５）面に接触時に床（５）に傷を付けず、通気孔（５ａ）へのササリ粒を掻出し、且つ、スクレーパブラシ（４３）面で残留籾を排出方向へはき寄せることができるような、ある程度の可撓性と剛性を有する金属または合成樹脂等の材料で作られている。
【００１９】
上記のようにスクリューコンベア（１７）の後方に毛（４２）先端を床（５）に接触させる各スクレーパブラシ（４３）を取付け、スクリューコンベア（１７）の後を各スクレーパブラシ（４３）が同じリード角（α）を保った姿勢で追従旋回し、１旋回当りスクレーパブラシ（４３）１枚分づつ残留籾を排出口（１３）方向へはき寄せ、順次内側のスクレーパブラシ（４３）に残留籾を受継がせることによって、従来では機械的に排出できなかったスパイラル（１９）とタンク床（５）間の隙間（Ｌ１）の残留籾を機械的に排出することができ、また床（５）面の通気孔（５ａ）のササリ粒もスクレーパブラシ（４３）は掻出すことができ、穀粒ロスをより少なくできると同時に、床（５）の通気孔（５ａ）の目詰りを防止して通気性を確保するから、タンク（１）の穀物乾燥機能の低下も防止できる。さらにスクレーパブラシ（４３）は適当なたわみにより適当に籾抜けを生じさせるため、スクリューコンベア（１７）が駆動モータに異状負荷がかかるのも防止できる。またスクレーパブラシ（４３）はコイルブラシ（４０）に比べ床（５）面との接触面積が多くより確実、且つ、効率良く残留籾の排出を行うことができる。
【００２０】
さらに、一組の各スクレーパブラシ（４３）はスクレーパ取付板（４４）に設けられた前後一対の取付孔（４５）（４６）にボルト（４７）とナット（４８）の締結部材によって取付けられるもので、その後取付孔（４６）を前取付孔（４５）を中心とする長孔に形成し、各スクレーパブラシ（４３）のリード角を前記のリード角（α）とスパイラル軸（１８）と直交する方向の（０°）に切換え可能に、各スクレーパブラシ（４３）をスクレーパ取付板（４４）に左右揺動自在に取付けると共に、スクレーパ取付板（４４）の後取付孔（４６）上面に構成する一本の連動杆（４９）に後取付孔（４６）に貫通するボルト（４７）及びそのナット（４８）を介して各スクレーパブラシ（４３）を連結し、連動杆（４９）のスライド操作によって一体的に各スクレーパブラシ（４３）のリード角を（α）と（０°）に切換え可能に構成している。
【００２１】
上記のように前記各スクレーパブラシ（４３）をスクレーパ取付板（４４）に一体的にリード角調節自在に取付けることにより、例えば残留籾の排出初期において、前記各スクレーパブラシ（４３）のリード角を「０°」にして１次排出作業（荒取り作業）を行い、残留籾の量が少なくなってから前記各スクレーパブラシ（４３）のリード角を（α）に切換えて２次排出作業（仕上げ作業）を行うなど、残留籾の量など作業条件に応じて各スクレーパブラシ（４３）のリード角を調節することによって、過負荷状態に至らせることなく作業条件に合った排出能力で残留籾の排出を効率良く行うことができる。
【００２２】
前記スクリューコンベア（１７）はスパイラル（１８）をタンク側壁（１８）ぎりぎりまで延設させることができず、タンク床（５）の半径と同じスクリューコンベア（１７）の作用半径を得ることができないため、この作用半径より外側のタンク（１）隅部の残留籾は排出することができない。
【００２３】
そこで、本実施例ではスクリューコンベア（１７）の作用半径より外側の残留籾をこの作用半径内にはき寄せる際取り装置（５０）を備えている。
【００２４】
図８及び図９は上記した際取り装置（５０）を示しており、この装置（５０）は、チェンカバー（５１）とでチェンケースを形成するチェンケース底板（５２）の前部下面から入力ケース（５３）を下方に一体延設すると共に、チェンケース底板（５２）の後部下面から出力ケース（５４）を下方に一体延設し、入力ケース（５３）に軸支する入力軸（５５）と出力ケース（５４）に軸支する出力軸（５６）の平行な２軸をこの上端側のチェンケース内で駆動及び従動スプロケット（５７）（５８）並びに伝動チェン（５９）を介して連動連結し、前記入力ケース（５３）の下部に入力軸（５５）と直角に軸支され、且つ、ケース（５３）内部で一対のベベルギヤ（６０）（６１）を介して入力軸（５５）に連動連結される駆動軸（５２）の回転を出力軸（５６）に伝える伝動ケース（６３）と、この伝動ケース（６３）後部の出力ケース（５４）下端から下方に突出させる出力軸（５６）端部に取付ける傘形状の際取りブラシ（６４）と、前記出力ケース（５４）の周面より際取りブラシ（６４）の上面に半径方向に配置する穀物案内板（６５）及び仕切ブラシ（６６）とで構成され、前記車軸（２７）に軸穴（６７）を形成し、前記入力ケース（５３）から突出させる駆動軸（６２）を車輪（２６）の外側から車軸（２７）の軸穴（６７）に挿入し、前記スパイラル軸（１８）と車軸（２７）を連動連結しているセットピン（２８）を介してこれら軸（１８）（２７）と一体的に駆動軸（６２）を連動連結し、スクリューコンベア（１７）の外端側の駆動車輪（２６）外側に着脱自在に取付け、且つ、アタッチメントとして取扱い可能に前記際取り装置（５０）を構成している。
【００２５】
前記際取り装置（５０）は、伝動ケース（６３）の入力ケース（５３）が車輪（２６）の外側中心部から上方に延設され、その入力ケース（５３）上端から後方に向ってチェンケースが略水平に延設され、そのチェンケース後端から下方に出力ケース（５４）が下方に延設され、その出力ケース（５４）下端側の際取りブラシ（６４）先端がスクリューコンベア（１７）後方外側のタンク（１）隅部の床（５）面に接地（接触）する状態に装着されるもので、前記際取りブラシ（６４）は出力ケース（５４）の下端より突出させた出力軸（５６）の下端部に中心部を嵌合させ、且つ、押え板（６８）及び止めボルト（６９）により軸方向及び周方向の移動を規制されて固着される断面コ形の円形状のホルダ（７０）に一端をたばねられ、このホルダ（３８）外周面から若干下向きの放射方向に毛（７１）を一定長さで立毛して形成した傘形状のブラシであり、床（５）面に対して際取りブラシ（６４）の前側略半周を接触させ、後側略半周を離反させるように、前記際取り装置（５０）は前低後高状に少し前傾姿勢に傾向けた状態で装着される。
【００２６】
前記際取りブラシ（６４）の毛長つまり外径はブラシ（６４）の外側先端が少したわんだ状態でタンク側壁（１８）に接触し、且つ、ブラシ（６４）の内側先端がスクリューコンベア（１７）の作用半径及び最外側のスクレーパブラシ（４１）の前端側旋回軌跡と同じか少し内側の床（５）面に接触するように形成され、また毛（７１）はタンク側壁（１８）及び床（５）に接触時に側壁（１８）及び床（５）に傷を付けず、床（５）の通気孔（５ａ）へのササリ粒を掻出し、且つ、際取りブラシ（７１）先端部で残留籾を排出口（１３）方向へはき寄せ、且つ、装置（５０）重量に耐えて自身の傘形状を保持することができるような、ある程度の可撓性と剛性を有する金属または合成樹脂等の材料で作られている。
【００２７】
上記のように、際取り装置（５０）をスクリューコンベア（１７）の外側に駆動連結を図って装着し、スクリューコンベア（１７）の作用半径外側のタンク（１）隅部の床（５）外周縁上を際取りブラシ（６４）が回転（自転）しながら追従旋回（公転）し、際取りブラシ（６４）前側からスクリューコンベア（１７）及びスクレーパブラシ（４３）の作用半径外側の残留籾をこの作用半径内側にはき寄せ、スクリューコンベア（１７）及びスクレーパ（４３）に受継がせることによって、従来では機械的に排出できなかったスクリューコンベア（１７）の作用半径外側のタンク（１）隅部の隅の隅まで残留籾を機械的に排出することができ、また床（５）外周縁部の通気孔（５ａ）のササリ粒も際取りブラシ（６４）は掻出すことができ、穀粒ロスをより少なくできると同時に、床（５）外周縁部の通気孔（５ａ）の目詰りを防止して通気性を確保するから、タンク（１）の穀物乾燥機能の低下も防止できる。さらに際取りブラシ（６４）は適当なたわみにより適当に籾抜けを生じるため、スクリューコンベア（１７）や駆動モータに異状負荷がかかるのも防止できる。また前記際取り装置（５０）は特別の動力源を設けなくて済み、構造簡単で製造コストが安く、セットピン（２８）１本で着脱可能で着脱作業も簡単に行うことができる。
【００２８】
さらに、上記際取り装置（５０）の穀物案内板（６５）は、出力ケース（５４）の周面に固着したブラケット（７２）に基端側がボルト（７３）を介して着脱自在に取付けられて、残留籾を出力ケース（５４）内側から後方内側に移送案内する半径方向に際取りブラシ（６４）上面側に立設固定され、その案内板（６５）と際取りブラシ（６４）との間に仕切ブラシ（６６）を設けるもので、仕切ブラシ（６６）は断面コ形で直線状のホルダ（７４）によって毛（７５）の一端がたばねられ、このホルダ（７４）から一方向に毛（７５）を一定長さで立毛する長方形状のほうき形のブラシであり、ホルダ（７４）底面を案内板（６５）下端縁に固着し、毛（７５）先端を際取りブラシ（６４）の上面に接触させると共に、案内板（６５）及び仕切ブラシ（６６）を際取りブラシ（６４）の外径より外側に延設させ、案内板（６５）及び仕切ブラシ（６６）の先端をスクリューコンベア（１７）及びスクレーパブラシ（４３）の作用半径内側に位置させ、仕切ブラシ（６６）先端側の毛（７５）先端を床（５）面に接触させ、際取りブラシ（６４）を超えて通過するタンク（１）隅部の残留籾を一枚の板状の案内板（６５）と仕切ブラシ（６６）によってスクリューコンベア（１７）及びスクレーパブラシ（４３）の作用半径内側に流し、スクリューコンベア（１７）及びスクレーパブラシ（４３）に受継がせるように構成している。
【００２９】

Therefore, it is possible to prevent the grain drying function of the tank (1) from being deteriorated. Further, since the coil brush (40) is appropriately pulled out by appropriate deflection, it is possible to prevent an abnormal load from being applied to the screw conveyor (17) and the drive motor. The coil brush (40) is connected to the sweep shield (29).spiralSince the gap with (18) is also eliminated at the same time, soot in this gap can be reliably transferred and discharged, and the scorpion grains for the lower part of the front end of the sweep shield (29) can also be scraped and discharged.

Reduces grain drying function of tank (1) because it can scrape and reduce grain loss and at the same time prevent clogging of the vent (5a) of the floor (5) to ensure air permeability. Can also be prevented. Furthermore, since the scraper brush (43) causes the punching to occur appropriately by appropriate deflection, it is possible to prevent the screw conveyor (17) from applying an abnormal load to the drive motor. Further, the scraper brush (43) has a larger contact area with the floor (5) surface than the coil brush (40), and can discharge the residual soot more reliably and efficiently.
