Description

【0001】
【産業上の利用分野】
本発明は、大豆、小豆、米、麦、蕎麦等の穀粒を一時貯留するグレンタンクの穀粒排出装置に係るものである。
【0002】
【従来技術】
従来公知の、実開平2−116935号公報には、機体フレームの下方に設けた走行装置と、機体フレームの前側に設けた刈取部と、機体フレームの上方位置に設けたグレンタンクと、該グレンタンク内の穀粒を排出する穀粒排出装置とを有し、該穀粒排出装置は、先端に穀物排出口を有しエンジンからの送風により穀粒を搬送する排出用筒部材の中間部をグレンタンクに接続した構成について記載されている。
【0003】
【発明が解決しようとする課題】
前記公知例は、排出用筒部材への送風をエンジンの排風を利用する点に課題がある。即ち、エンジンの排気ガスを利用するので、穀粒が汚染される可能性がある。
また、排出用筒部材の中間部をグレンタンクの排出部に単に接続しているだけであるので、穀粒が詰まるという課題があり、また、メンテナンスについて考慮されていない。また、グレンタンク内の穀粒の重量が排出部に掛かる点について考慮されていないので、排出が円滑でない。
また、グレンタンクから直接穀粒を排出できない。
【0004】
【発明の目的】
搬送穀粒の損傷の減少および穀粒汚染の回避、穀粒搬送の確実化・円滑化、メンテナンスの容易化、穀粒排出の円滑化・確実化、作業の容易化、作業効率の向上。
【0005】
【課題を解決するための手段】
本発明は、走行装置7の左右一側上方位置に脱穀装置2を、左右他側上方位置にグレンタンク3とを夫々設け、該グレンタンク3の漏斗部11には該タンク3内の穀粒を排出する穀粒排出装置13を設け、該穀粒排出装置13は、先端に穀物排出口16を有し送風機15からの高圧空気により穀粒を搬送する排出用筒部材14の中間部をグレンタンク3の穀粒を排出する排出部12に接続して構成し、該排出部12は、排出繰出機構100の下方に前記排出用筒部材14の中間部を接続した一端から他端に流動する高圧空気に排出繰出機構100から排出された穀粒を合流させるフィーダ107を設けて構成し、前記排出繰出機構100は円形のドラム101と該ドラム101の内周に回転しながら摺接する回転翼103とにより構成し、前記ドラム101は、その中心を前記漏斗部11の下部に対してずらせて設け、前記ドラム101の上部開口部106が前記回転翼103に対して斜め上方に位置するようにし、もって、前記ドラム101の上部開口部106の下部に各回転翼103間に形成する流入室105の側部を露出させて穀粒が流入室105に流入する流入部121を形成し、前記上部開口部106には該上部開口部106の開口面積を大小に調節する落下量調節体120を設け、前記フィーダ107は、該フィーダ107の下側の一端に前記排出用筒部材14の中間部を接続する上手側接続筒部110を、他端に前記前記排出用筒部材14の中間部を接続する下手側接続筒部111を夫々形成し、前記上手側接続筒部110側の内面は下方に至るに従い下手側接続筒部111に近づく上手側傾斜面113に形成し、該上手側傾斜面113には前記上手側接続筒部110の軸心方向に対して斜めに開口する空気流入口114を形成し、前記上手側傾斜面113の下縁には、前記空気流入口114の下縁を過ぎて下方に向かって前記下手側接続筒部111側に低く傾斜する凹部115を連続形成し、該凹部115はその中間部より前記下手側接続筒部111に近づくに従い高くなる傾斜面に形成し、前記フィーダ107の下手側接続筒部111側の上部内面は、下方に至るに従い前記下手側接続筒部111の空気排出口116に近づく下手側傾斜面117に形成したコンバインの排出装置としたものである。
【0006】
【実施例】
本発明の実施例を図面により説明すると、1は大豆、小豆、米、麦、蕎麦等の穀物を刈取り脱穀するコンバインの機体フレームであり、2は前記機体フレーム1の上方位置に設けた脱穀装置、3は前記脱穀装置2の側部に設けたグレンタンク、4は前記グレンタンク3の前側に空間5を置いて設けた操縦席、7は前記機体フレーム1の下方に設けた走行装置、8は前記脱穀装置2および前記操縦席4の前側に位置する刈取部である。
前記グレンタンク3には、前記脱穀装置2内に設けた一番コンベアの終端部に接続した穀物供給用揚穀装置10の上部を接続し、前記一番コンベアにより取出された穀物を貯留する。グレンタンク3の下部は、下方に至るに従い細く(狭く)なる漏斗部11に形成し、漏斗部11の下部にはグレンタンク3内の穀粒を排出する排出部12を設ける。排出部12には穀粒排出装置13の一部を構成する排出用筒部材14の中間部を接続する。
即ち、穀粒排出装置13は、排出用筒部材14の一端に圧縮空気(高圧空気、圧搾空気)を送風する送風機15を接続し、他端に穀物排出口16を形成し、中間部をグレンタンク3の排出部12に接続し、前記穀物排出口16が縦軸旋回および上下するように構成する。
【0007】
本実施例では、排出用筒部材14の基部側筒部17の基部に前記送風機15を接続し、基部側筒部17の先端は前記排出部12の上手側に接続し、排出部12の下手側には排出用筒部材14の中間筒部18の基部を接続し、中間筒部18の先端はグレンタンク3より突出させ、中間筒部18には上方に起立する縦排出筒部19を接続し、該縦排出筒部19に続いて横排出筒部20を設け、横排出筒部20の先端に前記穀物排出口16を形成している。本実施例では、縦排出筒部19と横排出筒部20を一体形成しているが、別体でもよい。
また、前記グレンタンク3の漏斗部11の後側には接続筒26を設け、接続筒26には下部縦軸27を介してL型状の下部メタル28を取付け、下部メタル28は前記機体フレーム1側に固定し、下部メタル28の上部には穀粒排出装置13の一部を構成する縦回転筒29を下部メタル28に対してモータ、シリンダ等の旋回用駆動源30により回転自在に取付ける。縦回転筒29の上部には取付部材31の基部をモータ、シリンダ等の上下用駆動源32により上下回動自在に取付け、取付部材31の先端側には支持横フレーム33を取付ける。
【0008】
そして、前記排出用筒部材14の中間筒部18は接続筒26から下部メタル28内に挿入し、中間筒部18に続く縦排出筒部19は縦回転筒29内を通して縦回転筒29の上端開口部より露出させ、縦排出筒部19に続く横排出筒部20を支持横フレーム33の側部に添わせて係止部材35により係止している。
前記係止部材35は、横向きU型形状に形成し、所定間隔を置いて複数固定し、各係止部材35内に横排出筒部20を挿通する。即ち、横排出筒部20は、金属等の剛体により形成した筒内に挿入して設けてもよいが、支持横フレーム33の側部に添わせて係止部材35により係止することで、軽量化が図れ、好適である。また、クランプと呼ばれ、バンド状の着脱自在のもので係止部材35を構成すると、着脱が容易になって、メンテナンスが容易になり、好適である。
また、本実施例の横排出筒部20は、支持横フレーム33の側部に添わせているが、上面および下面に添わせてもよい。
支持横フレーム33は、前記取付部材31を平面視前記縦回転筒29の開口部22に重合しないようにオフセットさせ、排出用筒部材14は支持横フレーム33の開口部22側の側面に添わせて設け、縦排出筒部19と横排出筒部20との間の屈曲部24が平面視略直線状になるように取付ける。
また、取付部材31の回動中心である取付軸23は、側面視開口部22の上方を外して(離れて)前記支持横フレーム33の長さ方向の始端または終端(前後)の何れか一方側に位置させて設け、縦排出筒部19と横排出筒部20との間の屈曲部24は、側面視屈曲部24の所謂アール(円弧状の屈曲部24の半径)を大きくする。
【0009】
しかして、前記排出用筒部材14は、送風機15に接続した基部側筒部17を前記縦回転筒29の外側(反脱穀装置2側、既刈地側)を排出部12に向けて伸ばし、排出部12を過ぎた所定位置にて縦回転筒29に向けて折り返す折り返し部38を形成し、折り返し部38より折り返した基部側筒部17を排出部12に接続し、該排出部12の縦回転筒29側に前記中間筒部18の始端を接続し、中間筒部18の終端は前記縦回転筒29に向かって伸ばす。
したがって、基部側筒部17は縦回転筒29側にある送風機15からの送風を折り返し部38により縦回転筒29に向けて排出部12に送風して穀粒を搬送し、しかも、基部側筒部17の長さを短くする。
しかして、前記排出用筒部材14は、その材質は任意であるが、一部または全部を変形可能な可撓性部材により形成し、少なくとも、縦回転筒29の上端開口部から突出する縦排出筒部19と横排出筒部20のうち支持横フレーム33の基部に係止した係止部分との間は変形可能な可撓性部材により形成すると、排出用筒部材14の縦排出筒部19に対して横排出筒部20の旋回を円滑にする。また、それ以外の部分は、合成樹脂あるいは金属等の剛体によって構成してもよく、例えば、縦排出筒部19を金属筒により形成すると、縦回転筒29を省略できる。
【0010】
また、排出用筒部材14の基部側筒部17および中間筒部18も伸縮自在で変形自在に構成すると、グレンタンク3のオープンに際して、着脱することがなく、オープン作業を容易にして、好適である。
また、排出用筒部材14の一部または全部は内部を目視可能な透明部材(半透明等を含み目視可能であればよい)により形成すると、メンテナンスを容易にして、好適である。特に、排出用筒部材14の横排出筒部20は支持横フレーム33の側部に添わせて係止部材35により係止して殆ど露出させているので、操縦席4から見ることができて、詰まりに対して素早く対応できる。
しかして、前記グレンタンク3は前記下部縦軸27および該下部縦軸27と同心の機体側の任意の固定部に設けた上部縦軸36を中心に機体側に対して側方に回動するように取付ける。
本実施例では、前記下部縦軸27および上部縦軸36をグレンタンク3の反脱穀装置2側の外側(既刈地側)に設け、グレンタンク3の前側を回動するようにしている。即ち、前記排出用筒部材14を挿通した縦回転筒29は、グレンタンク3の後部に設け、縦回転筒29を移動させることなくグレンタンク3の前側を側方回動させる。
40はグレンタンク3の前側に設けた下部ロック機構であり、グレンタンク3が回動しないように機体固定部に固定すればよく、その構成は任意であるが、一例を示すと、41は機体フレーム1側に軸止したフック、42は前記フック41が係合する係合ピン43を有しかつフック41を操作する操作レバー、44は操作レバー42の中間部を当接させてグレンタンク3の回動を停止させるグレンタンク3側に設けた係合部材である。また、45は上部ロック機構であり、前記脱穀装置2側に設けた係合体46に係合フック47を継脱させて、ロックする。
【0011】
しかして、前記送風機15は、グレンタンク3より後方に設ける。即ち、送風機15はグレンタンク3の後部より後方の固定部に設け、グレンタンク3の前側の刈取部8に対して重りの作用を期待する(図1、図2)。また、グレンタンク3の後側に設ける。
前記送風機15は前記機体フレーム1に固定の左右一対の取付フレーム55の上部枠56に固定する。各取付フレーム55は上部枠56の前部を一対の縦フレーム57の上下中間部に固定する。各上部枠56の後側は下方から前側に屈曲させて逆「コ」形状に形成し、下端部を機体フレーム1側に夫々固定する。
前記縦フレーム57の下部は機体フレーム1に固定し、縦フレーム57の上部には左右補強フレーム58に固定し、左右補強フレーム58の一端には支持部59を設け、支持部59は前記縦回転筒29の上下中間部を支持するように取付ける。支持部59の前部は左右方向の前側補強フレーム60に固定し、前側補強フレーム60の外端には前記グレンタンク3の回動中心となる上部縦軸36を軸装する。前側補強フレーム60の内端側には縦フレーム61を固定し、縦フレーム61の下端は機体フレーム1に固定する。前側補強フレーム60の内端および縦フレーム61および左右補強フレーム58には前後補強フレーム62を夫々固定し、前後補強フレーム62の前部は脱穀装置2の任意箇所に固定する。
したがって、支持部59を介して縦回転筒29と、取付フレーム55および縦フレーム57および左右補強フレーム58および前側補強フレーム60および縦フレーム61および前後補強フレーム62の夫々とは、互いが互いの強度メンバーとして構成し、作用する。
【0012】
しかして、前記取付フレーム55には載置台63を設け、載置台63に燃料タンク64を設け、燃料タンク64を送風機15の下方に配置する(図2、なお、図1では燃料タンク64は送風機15の下方ではなく、別途任意に配置している)。
しかして、前記機体フレーム1の所望位置には刈取脱穀カウンタギヤボックス66を設け、刈取脱穀カウンタギヤボックス66と前記排出用筒部材14との間に逆転増速ギヤボックス67を設け、逆転増速ギヤボックス67と刈取脱穀カウンタギヤボックス66との間に伝動入り切りクラッチ68を設ける。
前記刈取脱穀カウンタギヤボックス66の上部にはコンプレッサ69を設け、コンプレッサ69の入力プーリ70と刈取脱穀カウンタギヤボックス66の下部に設けた出力プーリ71との間にベルト72を掛け回し、ベルト72は刈取脱穀カウンタギヤボックス66の側部に設けたテンションプーリ73に掛け回し、テンションプーリ73は刈取脱穀カウンタギヤボックス66の側部に設けたステー74に取付ける。
図中、48はエンジン(原動機)、49はエンジン48のプーリと刈取脱穀カウンタギヤボックス66の中間プーリとの間に設けたベルト、51、52はベルトである。
しかして、前記グレンタンク3より前方にエンジン48を設け、前記脱穀装置2と前記グレンタンク3との間の空間54に前記エンジン48から前記送風機15に至る伝動機構の一部または全部を設ける。実施例では、平面視、前記ベルト49および前記刈取脱穀カウンタギヤボックス66および逆転増速ギヤボックス67およびベルト51、52の夫々を空間54内に配置している。なお、図では、グレンタンク3の内側側板が前記伝動機構と重複して図示されているが、漏斗部11の下方に位置している。
【0013】
しかして、前記伝動入り切りクラッチ68は、テンションクラッチプーリ75により構成し、テンションクラッチプーリ75はテンションアーム76の基部を縦の取付杆77に回動自在に取付け、取付杆77は刈取脱穀カウンタギヤボックス66と逆転増速ギヤボックス67の間に設ける。78は前記テンションクラッチプーリ75を入り切りさせる操作伝動部材である。
前記テンションクラッチプーリ75はベルト51の下張ベルト下面79に当接させ、上張ベルト下面80にはアイドルプーリー81を当接させ、アイドルプーリー81は前記取付杆77の上部または上端に取付ける。即ち、アイドルプーリー81は前記テンションクラッチプーリ75の略上方に位置するように取付杆77に取付ける。
しかして、逆転増速ギヤボックス67の出力プーリ82と前記送風機15の入力プーリ83との間に前記ベルト52を掛け回し、ベルト52にはテンションプーリ84を当接させ、テンションプーリ84はテンションアーム85の基部を前記逆転増速ギヤボックス67に回動自在に取付け、テンションアーム85はその下部を逆転増速ギヤボックス67に回動自在に取付け、テンションアーム85には逆転増速ギヤボックス67に位置調節自在に設けたテンションロッド86の下端を取付けて常時上方回動方向に引き、ベルト52を緊張させる。
【0014】
しかして、前記排出部12は、漏斗部11の下部に略一定量ずつ排出する排出繰出機構100を設ける。排出繰出機構100は、内周面が円形のドラム101101の中心に横回転軸102により放射方向に突き出てドラム101の内周に摺接する回転翼103を横回転軸102の回転方向に所定間隔を置いて複数設け、各回転翼103の間に穀粒を下方の落下口104まで案内する流入室105を形成する。前記ドラム101はその上部の上部開口部106を前記漏斗部11の下部に臨ませ、前記落下口104を後述するフィーダ107の上部に開口させて構成し、落下口104の下部は下方に至るに従い広がるように構成する。前記ドラム101より突出する横回転軸102には歯車(図示省略)を設け、該歯車には排出用モータ108の歯車(図示省略)との間にチエン109を掛け回す。
前記フィーダ107は前記排出部12の一部を構成し、フィーダ107の下側の一端には前記基部側筒部17の終端を接続する上手側接続筒部110を、他端には前記中間筒部18の始端を接続する下手側接続筒部111を夫々形成し、フィーダ107の上手側接続筒部110側の内面は側面視略垂直方向の縦面112を形成し、縦面112に続いて下方に至るに従い下手側接続筒部111に近づく上手側傾斜面113に形成し、上手側傾斜面113には前記上手側接続筒部110と連通する空気流入口114を開口させる。
【0015】
前記上手側傾斜面113の下縁には、空気流入口114の下縁を過ぎて下方に向かって下手側接続筒部111側に低く傾斜する凹部115を連続形成し、凹部115はその中間部より前記下手側接続筒部111に近づくに従い高くなる傾斜面に形成している。
また、フィーダ107の下手側接続筒部111側の上部内面は、下方に至るに従い下手側接続筒部111の空気排出口116に近づく下手側傾斜面117に形成する。前記上手側接続筒部110は終始同径であるが、前記下手側接続筒部111の内周は空気排出口116より終端に至るに従い大径に形成している。
しかして、前記排出繰出機構100は、前記ドラム101をグレンタンク3の漏斗部11の下部にボルト等により着脱自在に取付け、ドラム101の下部に前記フィーダ107の上部をボルト等により着脱自在に取付ける。したがって、前記のようにグレンタンク3を外側回動させると、排出部12のメンテナンスを容易にできる。即ち、排出繰出機構100はグレンタンク3の漏斗部11に取付けているので、グレンタンク3と共にオープンし、メンテナンスを容易にする。
この場合、前記排出用モータ108は、前記グレンタンク3の漏斗部11の下方に設けると、空間を有効利用できて、好適であり、また、排出部12を基準にグレンタンク3の回動中心から離れた回動端側に設けると、グレンタンク3をオープンさせたとき、ドラム101が邪魔にならずに排出用モータ108を露出させ、一層、メンテナンスを容易にでき、好適である。
【0016】
しかして、前記排出用モータ108はインバーターモータ等の可変速モータにより回転変更可能に構成し、回転変更することによりフィーダ107への落下量を変更可能に構成する。
また、前記上部開口部106には、上部開口部106の開口面積を大小に調節しうる落下量調節体120を設けると、穀粒の種類や性状によって最適な状態で、効率よく排出させる。即ち、排出繰出機構100はフィーダ107に継続的に定量の穀粒を落下させると、詰まりが防止できて好ましく、このとき、単に回転翼103の回転数を上げても所定回転数を越えると、各回転翼103によって形成される流入室流入室105の開口部が上部開口部106に対して開口している時間が短くなって、充分な量の穀粒が落下する以前に回転移動してしまうので、流入室105への流入量は却って減少し、排出繰出機構100による落下量は穀粒の流入室105への流入速度と回転翼103の回転数の相対関係によって、効率を向上させることになる。
そこで、単に、落下量調節体120により上部開口部106を広く、回転翼103の回転を早く、あるいは、落下量調節体120により上部開口部106を狭く、回転翼103の回転を遅くするだけでなく、落下量調節体120により上部開口部106を広く、回転翼103の回転を遅く、あるいは、落下量調節体120により上部開口部106を狭く、回転翼103の回転を早くする等の適宜の両者関係を設定することにより、穀粒の種類や性状によって最適な状態で、効率よく排出させる。
【0017】
実施例では、前記回転翼103の中心を前記漏斗部11の下部に対してずらせて設け、ドラム101の上部開口部106が回転翼103に対して斜め上方に位置するようにし、前記回転翼103を設けた側の漏斗部11に板状の落下量調節体120を出入り自在に取付けている。また、上部開口部106の下部に回転翼103の側部を露出させて穀粒が流入室105に流入する流入部121を形成するので、回転翼103とドラム101の内周とによる穀粒の挟み込みを減少させ、好適である。
しかして、前記送風機15の伝動入り切りクラッチ68と前記排出用モータ108とは、略同じタイミングで駆動させる。即ち、送風機15からの送風が遅れて詰まるのを防止する。実施例では、伝動入り切りクラッチ68を入りにした後に、タイムラグを設けて排出用モータ108のモータスイッチ122を入りにする。この場合、操作伝動部材78にはモータあるいはシリンダ等の操作駆動部123を設け、該123を制御部124によりコントロールすることにより伝動入り切りクラッチ68を入り切りする。
しかして、前記フィーダ107に替えて、排出繰出機構100のドラム101の下部に補助取出口125を有する補助取出部126を着脱交換自在に取付ける。前記補助取出部126の近傍には前記モータスイッチ122とは別途に排出用モータ108の近接操作スイッチ127を設ける。128は穀粒袋129を吊る場合には袋ホルダとして使用可能な係合部材である。
【0018】
しかして、図22は、別の排出部12の実施例を示し、前記略一定量ずつ排出する排出繰出機構100を省略し、排出用筒部材14からの高圧空気に穀粒を合流させるインジェクションフィーダ130を設ける。インジェクションフィーダ130は前記フィーダ107の上手側接続筒部110に、先端がスロート131(前記下手側接続筒部111)の空気排出口116近傍に臨み、先端に至るに従い小径となるノズル132を設けて構成し、前記スロート131は本体133に対して着脱自在にすると共に、ノズル132も本体に対して着脱自在に構成する。
また、図23、24は、前記スロート131は、本体133に対して縦軸134中心に回動自在に設け、インジェクションフィーダ130内のメンテナンス可能にしている。
しかして、前記フィーダ107およびインジェクションフィーダ130は、前記したようにグレンタンク3の漏斗部11の下方に設け、フィーダ107およびインジェクションフィーダ130の上部開口部135の上方のグレンタンク3内には落下規制ガイド136を設ける。落下規制ガイド136は中央側が高く前後または左右に至るに従い低く傾斜した一対の傾斜板137により構成し、前記上部開口部135の上方の穀粒の圧力を軽減させ、円滑に流入させる。
また、グレンタンク3の漏斗部11には、開閉自在の点検蓋138を設ける。点検蓋138は摺動あるいは回動させて、漏斗部11に設けた開口部を開口させる。
【0019】
(作用)
次に前記構成に基づく作用を述べる。
操縦席4に着座して機体を前進させ、分草体により穀稈を分草し、分草した穀稈をリールで掻込み刈刃により刈取り、刈取った穀稈を脱穀装置2へ供給して脱穀して風選し、一番物は一番コンベアにより取出され、穀物供給用揚穀装置により脱穀装置2の側部に設けたグレンタンク3に貯留する。
グレンタンク3の排出部12には、圧縮空気を送風する送風機15を接続した排出用筒部材14の中間部を接続し、排出部12の搬送下手側の排出用筒部材14に設けた穀物排出口16が縦軸旋回および上下するように構成した穀粒排出装置13を設けているから、グレンタンク3内に穀物が一杯になると、機体を圃場近傍に待機させたトラックの近傍にまで走行させ、穀物排出口16を前記トラックのタンク上方に位置させる。
この場合、穀物排出口16は上下および旋回自在であるから、トラックのタンクとの位置合わせを容易にする。また、穀物排出口16は上下および旋回自在であるから、トラックのタンクに一々係止する必要がなく、排出作業を容易にする。

この状態で送風機15を作動させると、グレンタンク3内の穀粒は漏斗部11から排出部12を通って排出用筒部材14の中間部に入り、送風機15からの圧搾空気により搬送された穀物が穀物排出口16よりトラックに設けたタンクに排出される。
この場合、グレンタンク3内の穀粒は排出部12より排出用筒部材14の中間部に流入するが、排出部12は漏斗部11の下部に略定量ずつ排出する排出繰出機構100を設けているから、ドラム101の上部開口部106から穀粒は各回転翼103の間の流入室105に入り、回転する回転翼103によりドラム101の下方の落下口104まで搬送され、落下口104より落下する。
即ち、穀粒は、後述するフィーダ107にて送風機15からの送風と合流して、搬送されるが、略定量ずつ落下して合流するから、各穀粒に当たる風圧が略一定となって、合流および空気搬送が円滑になる。落下量がばらばらだと、量が多いときは穀粒が詰まりやすく、量が少ないときは飛ばされてフィーダ107内に滞留することもあるが、これを防止する。
しかして、ドラム101の落下口104の下方にはフィーダ107の上部を接続しているから、落下口104より落下した穀粒は、フィーダ107の空気流入口114より入る送風により空気排出口116に飛ばされ、下手側接続筒部111から中間筒部18内に入り、そのまま高圧空気により穀物排出口16まで搬送されて排出される。
【0021】
また、フィーダ107は、下方に至るに従い下手側接続筒部111に近づく上手側傾斜面113に形成し、上手側傾斜面113には空気流入口114を開口させているから、落下した穀粒は上手側傾斜面113により下手側接続筒部111側に斜めに移動するように案内され、この状態で、空気流入口114からの送風に当たるので、円滑に、穀粒は搬送用空気に乗って移動する。
また、空気流入口114は上手側傾斜面113に斜めに開口しているので、空気流入口114の上部と下部とで風が穀粒に当たる時間差が発生し、合流が円滑になる。即ち、略垂直に落下する穀粒に真横から送風すると、空気流入口114に近い側に落下する穀粒のみに風圧が強く作用する傾向となるが、斜めに開口しているので、空気流入口114の上部では近い穀粒に当たり易く、下部では空気流入口114から下手側の離れた穀粒に搬送風を作用させ易く、穀粒は拡散されながら排出されるので、詰まりの発生を少なくする。
しかして、フィーダ107は、空気流入口114の下縁を過ぎても上手側傾斜面113に続けて下方に向かって下手側接続筒部111側に低く傾斜させて凹部115を形成し、凹部115はその中間部より前記下手側接続筒部111に近づくに従い高くなる傾斜面に形成し、前記下手側接続筒部111側の上部内面は、下方に至るに従い下手側接続筒部111に近づく傾斜面下手側傾斜面117に形成しているから、搬送用空気に合流した穀粒は、凹部115および下手側傾斜面117により空気排出口116に向けて案内されて、下手側接続筒部111内に入る。
【0022】
しかして、前記排出用モータ108はインバーターモータ等の可変速モータにより回転変更可能に構成しているから、回転変更することによりフィーダ107への落下量を変更でき、穀粒の種類や性状によって最適な状態で、効率よく排出させる。即ち、単に回転翼103の回転数を上げても所定回転数を越えると、流入室105の実質開口時間が短くなって、充分な量の穀粒が落下する以前に回転移動してしまうので、流入量は却って減少するから、穀粒の種類や性状によって、回転翼103の回転数を変更することにより、詰まりを防止しつつ落下効率を向上させる。
また、前記上部開口部106には、上部開口部106の開口面積を大小に調節しうる落下量調節体120を設けているから、回転翼103の回転数のみならず、上部開口部106の開口面積を調節することにより、一層、穀粒の種類や性状によって最適な状態で、効率よく排出させる。
しかして、前記送風機15の伝動入り切りクラッチ68と前記排出繰出機構100(排出用モータ108)とは、略同じタイミングで駆動を入りにするから、送風機15からの送風が遅れている状態で穀粒が落下するのを防止できて、詰まるのを防止する。また、伝動入り切りクラッチ68が切りの状態では、前記排出繰出機構100(排出用モータ108)を作動させない(排出用モータ108に通電しない)から、初期操作における誤操作によって、穀粒が詰まるのを防止する。
【0023】
即ち、実施例では、伝動入り切りクラッチ68の操作駆動部123を操作すると、この旨を制御部124が検出し、制御部124は伝動入り切りクラッチ68が入りになると、所定のタイムラグを設けて排出用モータ108のモータスイッチ122を入りにする。したがって、送風機15が作動して排出部12のフィーダ107内に充分穀粒を搬送しうるように空気が流れている状態で、穀粒を落下させるから、詰まりを防止する。
また、排出用モータ108の停止は、任意であるが、送風機15は排出用モータ108の停止後も送風を所定時間続行させると、排出用筒部材14内の穀粒が詰まるのを防止できて、好適である。この場合、排出繰出機構100の停止後、フィーダ107内の穀粒が穀物排出口16から全て排出するために要する時間を置いて停止するようにすると、詰まり防止が一層確実になって、好適である。
しかして、排出用筒部材14は、その材質は任意であるが、少なくとも、縦回転筒29の上端開口部から突出する縦排出筒部19と横排出筒部20のうち支持横フレーム33の基部に係止した係止部分との間は変形可能な可撓性部材により形成しているから、縦排出筒部19に対して横排出筒部20を旋回させるとき変形して、穀粒が詰まることなく旋回でき、位置合わせを容易にする。
【0024】
本実施例では、機体をトラックの近傍に走行させると、旋回用駆動源30により下部メタル28に対して縦回転筒29を回転させて横排出筒部20を縦回転筒29中心に旋回させ、横排出筒部20の穀物排出口16を前記トラックのタンク上方に位置させ、この状態で送風機15を作動させ、グレンタンク3内の穀粒は漏斗部11から排出部12を通って排出用筒部材14の中間筒部18に入り、送風機15からの圧搾空気により中間筒部18を通って前記縦回転筒29内の縦排出筒部19を上昇して横排出筒部20内に入り、横排出筒部20を通って穀物排出口16よりトラックに設けたタンクに排出する。
しかして、支持横フレーム33は、前記取付部材31を平面視前記縦回転筒29の開口部22に重合しないようにオフセットさせて設けているから、縦排出筒部19と横排出筒部20との間の屈曲部24は、取付部材31および支持横フレーム33に邪魔されないので、これらを避けるための曲げ部分が少なく、前記開口部22から支持横フレーム33の間平面視略直線状に配置できる。したがって、排出用筒部材14内を穀粒は円滑に移動し、搬送が円滑、確実になる。
また、排出用筒部材14は支持横フレーム33の開口部22側の側面に添わせて設けているから、開口部22から穀物排出口16までも平面視略直線状になって、搬送が円滑、確実になる。
【0025】
また、取付部材31の回動中心である取付軸23は、側面視開口部22の上方を外して(離れて)前記支持横フレーム33の長さ方向の始端または終端の何れか一方側に位置させて設けているから、縦排出筒部19と横排出筒部20との間の屈曲部24は、側面視屈曲部24の所謂アール(円弧状の屈曲部24の半径)を大きくする。したがって、排出用筒部材14内を穀粒は円滑に移動し、搬送が円滑、確実になる。
しかして、係止部材35は、横向きU型形状に形成し、所定間隔を置いて複数固定し、各係止部材35内に横排出筒部20を挿通しているから、金属等の剛体により形成した筒内に挿入するのに比し、軽量化が図れ、好適である。
しかして、前記排出用筒部材14は、送風機15に接続した基部側筒部17を前記縦回転筒29の外側(反脱穀装置2側、既刈地側)を排出部12に向けて伸ばし、排出部12を過ぎた所定位置にて縦回転筒29に向けて折り返す折り返し部38を形成し、折り返し部38より折り返した基部側筒部17を排出部12に接続し、該排出部12の縦回転筒29側に前記中間筒部18の始端を接続し、中間筒部18の終端は前記縦回転筒29に向かって伸ばしているから、縦回転筒29側にある送風機15からの送風を折り返し部38により縦回転筒29に向けて排出部12に送風して穀粒を搬送できる。
【0026】
したがって、合理的な配置となって、送風機15からグレンタンク3の排出部12までの基部側筒部17の長さを短くし、空気の圧力損失を減少させる。
しかして、前記グレンタンク3は前記下部縦軸27および上部縦軸36を中心に機体側に対して側方に回動するように構成しているから、グレンタンク3をオープンして、伝動機構等を開放し、メンテナンス作業を容易にしている。
この場合、前記下部縦軸27および上部縦軸36は、送風機15を設けた側に設け、グレンタンク3の回動端側に前記折り返し部38が位置する配置となるから、グレンタンク3をオープンさせるとき、排出用筒部材14を着脱する必要がなく、オープン作業を容易にする。
そして、後側にある送風機15に接続した基部側筒部17は縦回転筒29の外側(反脱穀装置2側、既刈地側)を排出部12に向けて伸ばして折り返し部38より折り返すから、一層、合理的な配置となって、送風機15からグレンタンク3の排出部12までの基部側筒部17の長さを短くし、空気の圧力損失を減少させる。
この場合、排出用筒部材14の基部側筒部17および中間筒部18は、伸縮自在で変形自在に構成しているから、グレンタンク3のオープンに際して、着脱することがなく、オープン作業を容易にして、好適である。
【0027】
また、排出用筒部材14の一部または全部は内部を目視可能な透明部材により形成しているから、メンテナンスを容易にして、好適であるだけでなく、特に、排出用筒部材14の横排出筒部20は支持横フレーム33の側部に添わせて係止部材35により係止して殆ど露出させているので、操縦席4から見ることができて、詰まりに対して素早く対応できる。
しかして、排出部12は、前記フィーダ107に替えて、排出繰出機構100のドラム101の下部に補助取出口補助取出口125を有する補助取出部補助取出部126を着脱交換自在に取付けているから、送風機15を使用することなく、グレンタンク3から穀粒を排出させることができ、操作性、作業性を向上させる。
即ち、補助取出口補助取出口125に穀粒袋穀粒袋129を装着して、排出繰出機構100を作動させると、穀粒袋穀粒袋129に穀粒を袋詰めして、排出作業を行える。したがって、トラックのタンクへの排出と袋詰めとの排出作業を選択できる。
この場合、前記補助取出部126の近傍には前記モータスイッチ122とは別途に排出用モータ108の近接操作スイッチ近接操作スイッチ127を設けているから、操作スイッチ近接操作スイッチ127により排出用モータ108を操作でき、操作性を向上させる。また、補助取出口補助取出口125の近傍には係合部材128を設けているから、穀粒袋129を吊って作業でき、操作性、作業性を向上させる。
【0028】
しかして、図22の別の排出部12の実施例では、前記略一定量ずつ排出する排出繰出機構100を省略し、排出用筒部材14からの高圧空気に穀粒を合流させるインジェクションフィーダ130を設けているから、簡単な構成となる。
この場合、スロート131とノズル132の何れか一方または両方は、本体133に対して着脱自在に取付けているから、メンテナンスを容易にする。
また、図23の実施例では、前記スロート131は、本体133に対して縦軸134中心に回動自在に設けているから、インジェクションフィーダ130内のメンテナンス可能にするだけでなく、一々取りはずす必要がなく、作業性を向上させる。
しかして、前記フィーダ107またはインジェクションフィーダ130は、前記したようにグレンタンク3の漏斗部11の下方に設け、フィーダ107またはインジェクションフィーダ130の上部開口部106(135)の上方のグレンタンク3内には落下規制ガイド136を設けているから、落下規制ガイド136はグレンタンク3内の穀粒を支持してタンク3内の下部に穀粒が集中するのを防止し、フィーダ107またはインジェクションフィーダ130の上部開口部135へ掛かる圧力を減少させる。したがって、穀粒はフィーダ107またはインジェクションフィーダ130の上部開口部へ円滑に流入し、詰まりを防止する。
【0029】
即ち、落下規制ガイド136は中央側が高く前後または左右に至るに従い低く傾斜した一対の傾斜板136により構成しているから、落下規制ガイド136上の穀粒を支持し、下方の穀粒が減少すると、その傾斜により上部開口部135の上方の穀粒を真上でなく側方から流入し、それゆえ、圧力を軽減させながら流入させることになる。したがって、落下規制ガイド136は穀粒を支持して上部開口部135の上方の圧力を軽減させる作用と、上部開口部135に穀粒を案内する作用とを奏する。
しかして、グレンタンク3の漏斗部11には、開閉自在の点検蓋138を設けているから、排出部12の上方の開口部から、点検、詰まり除去等のメンテナンス作業をでき、作業性を向上させる。
しかして、排出部12の排出繰出機構100は、ドラム101をグレンタンク3の漏斗部11の下部に着脱自在に取付け、ドラム101の下部にフィーダ107の上部を着脱自在に取付けて構成しているから、ドラム101およびフィーダ107の分解を容易にし、排出部12のメンテナンスを容易にできる。
この場合、グレンタンク3は下部縦軸27および上部縦軸36を中心に機体側に対して側方に回動するように構成しているから、グレンタンク3をオープンさせると、排出部12のメンテナンスを一層容易にする。即ち、排出繰出機構100はグレンタンク3の漏斗部11に取付けているので、グレンタンク3と共にオープンし、メンテナンスを容易にする。
【0030】
この場合、回転翼103を作動させる排出用モータ108は、排出部12を基準にグレンタンク3の回動中心から離れた回動端側に設けているから、グレンタンク3をオープンさせたとき、ドラム101が邪魔にならずに排出用モータ108を露出させ、一層、メンテナンスを容易にでき、好適である。
また、排出繰出機構100のドラム101は、回転翼103の軸心方向の側板(フランジ)を着脱自在に構成すると、側板71を外せてドラム101内のメンテナンスを容易にする。また、回転翼103も外せるので、一層、メンテナンスを容易にする。
【0031】

[0008]
Then, the intermediate cylinder portion 18 of the discharge cylinder member 14 is inserted into the lower metal 28 from the connection cylinder 26, and the vertical discharge cylinder portion 19 following the intermediate cylinder portion 18 passes through the vertical rotation cylinder 29 and the upper end of the vertical rotation cylinder 29. The horizontal discharge cylinder part 20 that is exposed from the opening and continues to the vertical discharge cylinder part 19 is attached to the side part of the support horizontal frame 33 and locked by a locking member 35.
The locking member 35 is formed in a laterally U-shaped shape, and a plurality of locking members 35 are fixed at a predetermined interval, and the horizontal discharge cylinder portion 20 is inserted into each locking member 35. That is, the horizontal discharge cylinder portion 20 may be provided by being inserted into a cylinder formed of a rigid body such as a metal, but by being locked by the locking member 35 along the side portion of the support horizontal frame 33, The weight can be reduced, which is preferable. Moreover, it is called a clamp, and if the latching member 35 is comprised with a band-shaped detachable thing, attachment / detachment becomes easy and a maintenance becomes easy, and it is suitable.
Moreover, although the horizontal discharge cylinder part 20 of the present embodiment is attached to the side part of the support horizontal frame 33, it may be attached to the upper surface and the lower surface.
The support horizontal frame 33 is offset so that the mounting member 31 does not overlap the opening 22 of the vertical rotating cylinder 29 in plan view, and the discharge cylinder member 14 is attached to the side surface of the support horizontal frame 33 on the opening 22 side.

Thus, although the material of the discharge cylinder member 14 is arbitrary, a part or all of the discharge cylinder member 14 is formed of a deformable flexible member, and at least a vertical discharge projecting from the upper end opening of the vertical rotation cylinder 29. When the space between the cylindrical portion 19 and the locking portion locked to the base of the supporting horizontal frame 33 is formed by a deformable flexible member, the vertical discharging cylindrical portion 19 of the discharging cylindrical member 14 is formed. In contrast, the horizontal discharge cylinder portion 20 is smoothly turned. Further, the other portions may be formed of a rigid body such as synthetic resin or metal. For example, when the vertical discharge cylinder portion 19 is formed of a metal cylinder, the vertical rotation cylinder 29 can be omitted.
[0010]
Further, if the base side cylinder part 17 and the intermediate cylinder part 18 of the discharge cylinder member 14 are also extendable and deformable, it is preferable that the opening operation can be facilitated without being attached or detached when the glen tank 3 is opened. is there.

In the figure, 48 is an engine (prime mover), 49 is a belt provided between a pulley of the engine 48 and an intermediate pulley of a cutting and threshing counter gear box 66, and 51 and 52 are belts.
Thus, an engine 48 is provided in front of the Glen tank 3, and a part or all of a transmission mechanism from the engine 48 to the blower 15 is provided in a space 54 between the threshing device 2 and the Glen tank 3. In the embodiment, the belt 49, the cutting / threshing counter gear box 66, the reverse rotation speed increasing gear box 67, and the belts 51, 52 are arranged in the space 54 in plan view. In the figure, the inner side plate of the Glen tank 3 is shown overlapping with the transmission mechanism, but is located below the funnel portion 11.
[0013]
Thus, the transmission cut-off clutch 68 is constituted by a tension clutch pulley 75. The tension clutch pulley 75 is rotatably attached to the base of a tension arm 76 on a vertical attachment rod 77, and the attachment rod 77 is a cutting and threshing counter gear box. 66 and a reverse speed increasing gear box 67.

The idle pulley 81 is attached to the upper or upper end of the attachment rod 77. That is, the idle pulley 81 is attached to the attachment rod 77 so as to be positioned substantially above the tension clutch pulley 75.
Thus, the belt 52 is wound around the output pulley 82 of the reverse speed increasing gear box 67 and the input pulley 83 of the blower 15, and the tension pulley 84 is brought into contact with the belt 52. The tension pulley 84 is a tension arm.

A lower end of a tension rod 86 provided so as to be adjustable in position is attached and pulled in the upward rotation direction at all times, and the belt 52 is tensioned.
[0014]
Thus, the discharge unit 12 is provided with a discharge feeding mechanism 100 that discharges a substantially constant amount below the funnel unit 11. The discharge / feeding mechanism 100 has a rotating blade 103 that protrudes in the radial direction from the center of the drum 101101 whose inner peripheral surface is circular and is in sliding contact with the inner periphery of the drum 101 at a predetermined interval in the rotational direction of the horizontal rotating shaft 102. An inflow chamber 105 that guides the grains to the lower drop port 104 is formed between the rotary blades 103. The drum 101 is configured such that the upper opening 106 at the upper part faces the lower part of the funnel part 11, and the dropping port 104 is opened at the upper part of a feeder 107 to be described later. Configure to spread. A gear (not shown) is provided on the horizontal rotation shaft 102 protruding from the drum 101, and a chain 109 is wound around the gear (not shown) of the discharge motor 108.
The feeder 107 constitutes a part of the discharge unit 12, the upper side connecting cylinder part 110 that connects the terminal end of the base side cylinder part 17 is connected to the lower end of the feeder 107, and the intermediate cylinder is connected to the other end. The lower connection cylinder 111 connecting the starting ends of the portions 18 is formed, and the inner surface of the feeder 107 on the upper connection cylinder 110 side forms a vertical surface 112 in a substantially vertical direction when viewed from the side. The upper inflow surface 114 is formed on the upper side inclined surface 113 that approaches the lower side connection cylinder portion 111 as it goes downward, and an air inflow port 114 that communicates with the upper side connection cylinder portion 110 is opened in the upper side inclination surface 113.
[0015]
On the lower edge of the upper-side inclined surface 113, a concave portion 115 that is inclined downward toward the lower-side connecting tube portion 111 toward the lower side passing through the lower edge of the air inlet 114 is continuously formed. It forms in the inclined surface which becomes higher as it approaches the said lower side connection cylinder part 111 more.
Further, the upper inner surface on the lower connection cylinder portion 111 side of the feeder 107 is formed on a lower inclined surface 117 that approaches the air discharge port 116 of the lower connection cylinder portion 111 as it goes downward. The upper connection cylinder 110 has the same diameter from beginning to end, but the inner periphery of the lower connection cylinder 111 is formed to have a larger diameter from the air outlet 116 to the end.
Thus, the discharging and feeding mechanism 100 detachably attaches the drum 101 to the lower portion of the funnel portion 11 of the glen tank 3 with a bolt or the like, and attaches the upper portion of the feeder 107 to the lower portion of the drum 101 with a bolt or the like. . Therefore, if the Glen tank 3 is rotated outward as described above, the maintenance of the discharge unit 12 can be facilitated. That is, since the discharge / feeding mechanism 100 is attached to the funnel portion 11 of the Glen tank 3, it opens together with the Glen tank 3 to facilitate maintenance.
In this case, it is preferable that the discharge motor 108 is provided below the funnel portion 11 of the Glen tank 3 so that the space can be effectively used. Further, the rotation center of the Glen tank 3 is based on the discharge portion 12. When the glen tank 3 is opened, the drum 101 is not obstructed, and the discharge motor 108 is exposed without being disturbed, so that maintenance can be further facilitated.
[0016]
Thus, the discharge motor 108 can be changed in rotation by a variable speed motor such as an inverter motor, and the fall amount to the feeder 107 can be changed by changing the rotation.
Moreover, if the fall amount adjustment body 120 which can adjust the opening area of the upper opening part 106 to the size is provided in the said upper opening part 106, it will be discharged | emitted efficiently in the optimal state by the kind and property of a grain. In other words, it is preferable that the discharging and feeding mechanism 100 continuously drop a fixed amount of grains in the feeder 107 to prevent clogging. At this time, if the rotational speed of the rotary blade 103 is simply increased and the predetermined rotational speed is exceeded, The time during which the opening of the inflow chamber / inflow chamber 105 formed by each rotor blade 103 is open to the upper opening 106 is shortened, and the rotational movement occurs before a sufficient amount of grain falls. Therefore, the amount of inflow into the inflow chamber 105 is decreased, and the amount of fall by the discharge feeding mechanism 100 is to improve efficiency by the relative relationship between the flow rate of the grain into the inflow chamber 105 and the rotational speed of the rotary blade 103. Become.
Therefore, the upper opening 106 is widened by the drop amount adjusting body 120 and the rotating blade 103 is rotated faster, or the upper opening 106 is narrowed by the falling amount adjusting body 120 and the rotation of the rotating blade 103 is slowed. However, the upper opening 106 is widened by the drop amount adjusting body 120 and the rotation of the rotary blade 103 is slow, or the upper opening 106 is narrowed by the drop amount adjusting body 120 and the rotation of the rotary blade 103 is accelerated. By setting both relationships, it is efficiently discharged in an optimal state depending on the type and properties of the grain.
[0017]
In the embodiment, the center of the rotary blade 103 is shifted with respect to the lower portion of the funnel portion 11 so that the upper opening 106 of the drum 101 is positioned obliquely upward with respect to the rotary blade 103. A plate-shaped drop amount adjusting body 120 is attached to the funnel portion 11 on the side provided with slidably. Moreover, since the side part of the rotary blade 103 is exposed to the lower part of the upper opening 106 to form an inflow part 121 through which the grain flows into the inflow chamber 105, the grain of the rotary blade 103 and the inner periphery of the drum 101 is reduced. It is preferable to reduce pinching.
Accordingly, the transmission on / off clutch 68 of the blower 15 and the discharge motor 108 are driven at substantially the same timing. That is, the air blow from the blower 15 is prevented from being delayed and clogged. In the embodiment, after the transmission on / off clutch 68 is turned on, a time lag is provided to turn on the motor switch 122 of the discharging motor 108. In this case, the operation transmission member 78 is provided with an operation drive unit 123 such as a motor or a cylinder, and the transmission on / off clutch 68 is turned on and off by controlling the 123 by the control unit 124.
Thus, in place of the feeder 107, an auxiliary take-out portion 126 having an auxiliary take-out port 125 is attached to the lower portion of the drum 101 of the discharge / feeding mechanism 100 in a detachable and replaceable manner. A proximity operation switch 127 for the discharge motor 108 is provided in the vicinity of the auxiliary extraction portion 126 separately from the motor switch 122. Reference numeral 128 denotes an engaging member that can be used as a bag holder when the grain bag 129 is suspended.
[0018]
Thus, FIG. 22 shows another embodiment of the discharge unit 12, omitting the discharge feeding mechanism 100 that discharges the substantially constant amount, and joining the grain to the high-pressure air from the discharge cylinder member 14. 130 is provided. The injection feeder 130 is provided with a nozzle 132 that has a distal end facing the vicinity of the air discharge port 116 of the throat 131 (the lower connection cylinder 111) on the upper connection cylinder 110 of the feeder 107 and has a diameter that decreases toward the distal end. The throat 131 is configured to be detachable from the main body 133, and the nozzle 132 is also configured to be detachable from the main body.
23 and 24, the throat 131 is provided so as to be rotatable about the longitudinal axis 134 with respect to the main body 133 so that maintenance in the injection feeder 130 is possible.
Thus, the feeder 107 and the injection feeder 130 are provided below the funnel portion 11 of the Glen tank 3 as described above, and the fall restriction is placed in the Glen tank 3 above the upper opening 135 of the feeder 107 and the injection feeder 130. A guide 136 is provided. The drop regulation guide 136 is constituted by a pair of inclined plates 137 that are high at the center side and are inclined downward as they extend from front to back or from left to right, reducing the pressure of the grains above the upper opening 135 and allowing them to flow smoothly.
The funnel portion 11 of the Glen tank 3 is provided with an inspection lid 138 that can be opened and closed. The inspection lid 138 is slid or rotated to open the opening provided in the funnel portion 11.
[0019]
(Function)
Next, the operation based on the configuration will be described.
Sit in the cockpit 4 to advance the aircraft, weed the cereals with the weeds, scrape the cereals with the reels, cut with the cutting blade, and supply the harvested cereals to the threshing device 2 Threshing and wind-selection, the first thing is taken out by the first conveyor, and stored in the grain tank 3 provided on the side of the threshing device 2 by the grain supply cerealing device.
An intermediate portion of a discharge cylinder member 14 connected to a blower 15 for blowing compressed air is connected to the discharge section 12 of the Glen tank 3, and the grain discharge provided on the discharge cylinder member 14 on the lower conveyance side of the discharge section 12 is connected. Since the grain discharging device 13 is provided so that the outlet 16 swivels in the vertical axis and moves up and down, when the grain is full in the glen tank 3, the machine body is made to travel to the vicinity of the truck that is in the vicinity of the field. The grain outlet 16 is positioned above the tank of the truck.
In this case, since the grain discharge port 16 can be moved up and down and swiveled, the alignment with the tank of the truck is facilitated. Further, since the grain discharge port 16 can be moved up and down and swiveled, it is not necessary to be locked to the tank of the truck one by one, thereby facilitating the discharge operation.
[0020]
When the blower 15 is operated in this state, the grains in the Glen tank 3 enter the intermediate portion of the discharge cylinder member 14 from the funnel portion 11 through the discharge portion 12 and are conveyed by the compressed air from the blower 15. Is discharged from the grain outlet 16 to a tank provided in the truck.
In this case, the grain in the Glen tank 3 flows from the discharge portion 12 into the middle portion of the discharge cylinder member 14, and the discharge portion 12 is provided with a discharge feeding mechanism 100 that discharges almost a fixed amount at the bottom of the funnel portion 11. Therefore, the grain enters the inflow chamber 105 between the rotary blades 103 from the upper opening 106 of the drum 101, is conveyed to the drop port 104 below the drum 101 by the rotating rotary blade 103, and drops from the drop port 104. To do.
That is, the grain is transported by being fed with the air blown from the blower 15 by a feeder 107 described later, but since it drops and joins by a substantially fixed amount, the wind pressure hitting each grain becomes substantially constant, and the grain is joined. And air conveyance becomes smooth. When the amount of fall is different, the grains are easily clogged when the amount is large, and when the amount is small, they may be skipped and stay in the feeder 107, but this is prevented.
Since the upper part of the feeder 107 is connected to the lower side of the dropping port 104 of the drum 101, the grains dropped from the dropping port 104 are sent to the air discharge port 116 by air blowing from the air inlet 114 of the feeder 107. It is blown off, enters the intermediate cylinder part 18 from the lower side connection cylinder part 111, is conveyed to the grain outlet 16 by high-pressure air as it is, and is discharged.
[0021]
Further, the feeder 107 is formed on the upper-side inclined surface 113 that approaches the lower-side connecting cylinder portion 111 as it goes downward, and since the air inlet 114 is opened in the upper-side inclined surface 113, the dropped grain is It is guided by the upper side inclined surface 113 to move obliquely toward the lower side connecting tube part 111 side, and in this state, the air blows from the air inlet 114, so the grains smoothly move on the conveying air. To do.
In addition, since the air inlet 114 opens obliquely in the upper-side inclined surface 113, a time difference in which the wind hits the grain occurs between the upper part and the lower part of the air inlet 114, and the merging is smooth. That is, when air is blown from the side to a grain falling substantially vertically, the wind pressure tends to act strongly only on the grain falling to the side close to the air inlet 114, but since it is opened obliquely, the air inlet It is easy to hit a close grain at the upper part of 114, and it is easy to make a conveyance wind act on the grain far from the air inlet 114 at the lower part, and the grain is discharged while being diffused, so that the occurrence of clogging is reduced.
Thus, even after the lower edge of the air inlet 114 is passed, the feeder 107 is inclined downward toward the lower connection cylinder 111 toward the lower side connecting cylinder part 111 following the upper side inclined surface 113 to form the concave part 115. Is formed as an inclined surface that becomes higher as it approaches the lower connection cylinder 111 from its middle part, and the upper inner surface on the lower connection cylinder 111 side is an inclined surface that approaches the lower connection cylinder 111 as it goes downward Since it is formed on the lower-side inclined surface 117, the grain that has merged with the conveying air is guided toward the air discharge port 116 by the recess 115 and the lower-side inclined surface 117, and enters the lower-side connecting cylinder portion 111. enter.
[0022]
Since the discharging motor 108 can be changed in rotation by a variable speed motor such as an inverter motor, the amount of fall to the feeder 107 can be changed by changing the rotation, which is optimal depending on the type and properties of the grain. In an efficient state. That is, even if the rotational speed of the rotary blade 103 is simply increased, if the predetermined rotational speed is exceeded, the substantial opening time of the inflow chamber 105 is shortened, and the rotational movement occurs before a sufficient amount of the grain falls. Since the amount of inflow decreases, the drop efficiency is improved while preventing clogging by changing the number of rotations of the rotor blade 103 according to the type and properties of the grains.
In addition, since the upper opening 106 is provided with a drop amount adjusting body 120 that can adjust the opening area of the upper opening 106 to be larger or smaller, not only the rotational speed of the rotary blade 103 but also the opening of the upper opening 106 is provided. By adjusting the area, it is efficiently discharged in an optimum state depending on the type and properties of the grain.
Therefore, since the transmission on / off clutch 68 of the blower 15 and the discharge / feeding mechanism 100 (discharge motor 108) are driven at substantially the same timing, the grain is blown in a state where the blown air from the blower 15 is delayed. Can prevent falling and clogging. Further, when the transmission on / off clutch 68 is in a disconnected state, the discharge feeding mechanism 100 (the discharge motor 108) is not operated (the discharge motor 108 is not energized), so that the grain is prevented from being clogged due to an erroneous operation in the initial operation. To do.
[0023]
In other words, in the embodiment, when the operation driving unit 123 of the transmission on / off clutch 68 is operated, the control unit 124 detects this, and when the transmission on / off clutch 68 is engaged, the control unit 124 provides a predetermined time lag for discharging. The motor switch 122 of the motor 108 is turned on. Therefore, clogging is prevented because the blower 15 is activated and the grain is dropped in a state where the air is flowing so that the grain can be sufficiently conveyed into the feeder 107 of the discharge unit 12.
The discharge motor 108 can be arbitrarily stopped. However, if the blower 15 continues blowing for a predetermined time after the discharge motor 108 is stopped, it is possible to prevent the grains in the discharge cylinder member 14 from being clogged. Is preferable. In this case, if the grain in the feeder 107 is stopped after a period of time required for discharging all the grains in the feeder 107 from the grain outlet 16 after the discharge and feeding mechanism 100 is stopped, the prevention of clogging is further ensured, which is preferable. is there.
Thus, although the material of the discharge cylinder member 14 is arbitrary, at least the base part of the supporting horizontal frame 33 among the vertical discharge cylinder part 19 and the horizontal discharge cylinder part 20 protruding from the upper end opening of the vertical rotation cylinder 29. Since it is formed by a flexible member that can be deformed between the locking portion and the locking portion that is locked to the vertical discharging cylinder portion 19, the horizontal discharging cylinder portion 20 is deformed when swung with respect to the vertical discharging cylinder portion 19, and the grains are clogged. It can be swiveled without making it easy to align.
[0024]
In the present embodiment, when the aircraft is driven in the vicinity of the track, the vertical rotation cylinder 29 is rotated with respect to the lower metal 28 by the turning drive source 30 to rotate the horizontal discharge cylinder portion 20 around the vertical rotation cylinder 29, The grain discharge port 16 of the horizontal discharge cylinder part 20 is positioned above the tank of the truck, and the blower 15 is operated in this state, and the grains in the Glen tank 3 pass from the funnel part 11 through the discharge part 12 to the discharge cylinder. The intermediate cylinder part 18 of the member 14 is entered, the compressed air from the blower 15 passes through the intermediate cylinder part 18 and ascends the vertical discharge cylinder part 19 in the vertical rotary cylinder 29 and enters the horizontal discharge cylinder part 20. It passes through the discharge cylinder 20 and is discharged from the grain discharge port 16 to a tank provided in the truck.
Thus, the support horizontal frame 33 is provided by offsetting the mounting member 31 so as not to overlap the opening 22 of the vertical rotation cylinder 29 in plan view. Therefore, the vertical discharge cylinder part 19 and the horizontal discharge cylinder part 20 Since the bent portion 24 is not obstructed by the mounting member 31 and the supporting horizontal frame 33, there are few bent portions to avoid them, and the portion between the opening 22 and the supporting horizontal frame 33 can be arranged in a substantially straight line shape in plan view. . Therefore, the grain moves smoothly in the discharge cylinder member 14, and the conveyance is smooth and reliable.
In addition, since the discharge cylinder member 14 is provided along the side surface of the support horizontal frame 33 on the opening 22 side, the opening 22 to the grain discharge port 16 are also substantially straight in plan view, so that the conveyance is smooth. , Sure.
[0025]
Further, the mounting shaft 23, which is the center of rotation of the mounting member 31, is located on either the start or end side in the length direction of the support lateral frame 33 with the upper side of the opening 22 in the side view removed (separated). Therefore, the bent portion 24 between the vertical discharge cylinder portion 19 and the horizontal discharge cylinder portion 20 increases the so-called rounded radius (the radius of the arc-shaped bent portion 24) of the side view bent portion 24. Therefore, the grain moves smoothly in the discharge cylinder member 14, and the conveyance is smooth and reliable.
Thus, the locking member 35 is formed in a lateral U shape, fixed in plural at predetermined intervals, and the horizontal discharge cylinder portion 20 is inserted into each locking member 35. Compared to insertion into the formed cylinder, the weight can be reduced, which is preferable.
Thus, the discharge cylinder member 14 extends the base side cylinder part 17 connected to the blower 15 toward the discharge part 12 with the outside of the vertical rotation cylinder 29 (the anti-threshing device 2 side, the already cut ground side), A folded portion 38 that is folded back toward the vertical rotary cylinder 29 is formed at a predetermined position past the discharge portion 12, the base side cylinder portion 17 that is folded back from the folded portion 38 is connected to the discharge portion 12, and the vertical portion of the discharge portion 12 is Since the start end of the intermediate cylinder part 18 is connected to the rotary cylinder 29 side and the end of the intermediate cylinder part 18 extends toward the vertical rotary cylinder 29, the air blown from the blower 15 on the vertical rotary cylinder 29 side is folded back. The portion 38 can blow the air toward the discharge portion 12 toward the vertical rotating cylinder 29 and convey the grain.
[0026]
Therefore, it becomes rational arrangement | positioning, the length of the base side cylinder part 17 from the air blower 15 to the discharge part 12 of the glen tank 3 is shortened, and the pressure loss of air is reduced.
Thus, since the Glen tank 3 is configured to rotate laterally with respect to the airframe side about the lower longitudinal axis 27 and the upper longitudinal axis 36, the Glen tank 3 is opened and the transmission mechanism is opened. Etc., making maintenance work easier.
In this case, the lower vertical axis 27 and the upper vertical axis 36 are provided on the side where the blower 15 is provided, and the folded portion 38 is positioned on the rotating end side of the Glen tank 3, so that the Glen tank 3 is opened. When this is done, it is not necessary to attach or detach the discharge cylinder member 14, and the opening operation is facilitated.
And since the base side cylinder part 17 connected to the air blower 15 on the rear side extends toward the discharge part 12 by extending the outer side of the vertical rotating cylinder 29 (the anti-threshing device 2 side and the already cut yard side) from the folding part 38. Furthermore, it becomes a more rational arrangement, and the length of the base side cylinder part 17 from the blower 15 to the discharge part 12 of the Glen tank 3 is shortened, and the pressure loss of air is reduced.
In this case, the base side cylinder part 17 and the intermediate cylinder part 18 of the discharge cylinder member 14 are configured to be extendable and deformable, so that when the glen tank 3 is opened, it is not attached and detached, and the opening operation is easy. Thus, it is preferable.
[0027]
Further, since a part or all of the discharge cylinder member 14 is formed of a transparent member that allows the inside to be visually observed, it is not only suitable for facilitating maintenance, but in particular, the horizontal discharge of the discharge cylinder member 14 Since the cylindrical portion 20 is almost exposed by being locked by the locking member 35 along the side portion of the supporting horizontal frame 33, it can be seen from the cockpit 4 and can quickly cope with clogging.
Therefore, the discharge unit 12 replaces the feeder 107 with an auxiliary extraction unit auxiliary extraction unit 126 having an auxiliary extraction unit auxiliary extraction port 125 attached to the lower portion of the drum 101 of the discharge feeding mechanism 100 in a detachable and replaceable manner. The grain can be discharged from the glen tank 3 without using the blower 15 and the operability and workability are improved.
That is, when the grain bag grain bag 129 is attached to the auxiliary outlet 125 and the discharge feeding mechanism 100 is operated, the grain bag is packed in the grain bag 129 and the discharging operation is performed. Yes. Accordingly, it is possible to select the discharge operation of discharging into the tank of the truck and packing with a bag.

And improve workability.
Thus, the feeder 107 or the injection feeder 130 is provided below the funnel portion 11 of the Glen tank 3 as described above, and is placed in the Glen tank 3 above the upper opening 106 (135) of the feeder 107 or the injection feeder 130. Since the drop restriction guide 136 is provided, the drop restriction guide 136 supports the grain in the Glen tank 3 and prevents the grain from concentrating on the lower part in the tank 3, so that the feeder 107 or the injection feeder 130 The pressure applied to the upper opening 135 is reduced. Therefore, the grain smoothly flows into the upper opening of the feeder 107 or the injection feeder 130 to prevent clogging.
[0029]
That is, since the fall regulation guide 136 is composed of a pair of inclined plates 136 that are high on the center side and are lowered toward the front and rear or left and right, the grain on the fall regulation guide 136 is supported and the lower grain is reduced. , The inclination causes the grains above the upper opening 135 to flow from the side rather than directly above, and therefore flow while reducing the pressure. Accordingly, the drop regulation guide 136 has an effect of reducing the pressure above the upper opening 135 by supporting the grain and an effect of guiding the grain to the upper opening 135.
Since the funnel 11 of the Glen tank 3 is provided with an openable / closable inspection lid 138, maintenance work such as inspection and removal of clogs can be performed from the opening above the discharge part 12, thereby improving workability. Let
