Description

【0001】
【発明の属する技術分野】
本発明は、左右一対の履帯式走行装置にて、前記走行機体の高さ及び走行機体の左右傾斜を調節することができるようにしたコンバインに関するものである。
【0002】
【従来の技術】
圃場の凹凸や軟弱度に応じて、左右一対の履帯式走行装置のうちの一方または両方を昇降させて、その上のコンバインの走行機体の左右が傾斜しないように制御することは、例えば特開平1−291720号公報、特公平6−69329号公報等にて開示されている。
【0003】
そして、特公平6−69329号公報では、走行機体が傾いたとき、その傾きを修正するように、前記左右一対の履帯式走行装置をそれぞれ単独にて昇降駆動するため、左右一対の油圧シリンダと、該各油圧シリンダのピストンロッドに連結した前後一対のベルクランクレバーとを走行機体側に装着し、各ベルクランクレバーの後端を履帯式走行装置におけるトラックフレームに連結して、走行機体に対して履帯式走行装置が相対的に昇降するように構成すると共に、前記各油圧シリンダのピストンロッドの移動量を検出して、走行機体の左右に対する左右各履帯式走行装置の相対高さを検出するための相対高さ検出手段を、走行機体の側方外面に配置することを提案している。
【0004】
【発明が解決しようとする課題】
しかしながら、履帯式走行装置では、圃場走行時に、履帯の表面に付着した土や泥を走行機体に近い走行装置の上側に持ち運ぶため、相対高さ検出手段に泥被りが発生しやすく、当該相対高さ検出手段の作動不良や故障の原因となるという問題があった。
【0005】
また、前記特公平6−69329号公報では、ボリューム式の相対高さ検出手段を、履帯式走行装置を昇降駆動させるときに回動するベルクランクレバーの外側面に固定したものであるから、その相対高さ検出手段の検出信号を走行機体に装着した電子式制御装置に伝達するための通信線も絶えず揺れ動いたり、当該通信線に泥や土の付着の重量・衝撃が作用して、断線事故の原因となるという問題もあった。
【0006】
本発明は、この問題を解消したコンバインを提供することを技術的課題とするものである。
【0007】
【課題を解決するための手段】
この技術的課題を達成するため、請求項1に記載の発明のコンバインは、脱穀装置と穀粒タンクを左右並列状に搭載した走行機体の下方に左右一対の履帯式走行装置を各々独立的に昇降操作する左右一対の昇降駆動手段と、走行機体の左右傾斜角度を所定角度に保持するように前記昇降駆動手段を作動させる制御装置とを備えたコンバインであって、走行機体側に中途部を各々上下回動自在に枢支した前後一対のレバーの各アーム部を前記左右各履帯式走行装置におけるトラックフレームに各々枢着し、前後一対のレバーの上向き基部間を前後長手のロッド部材にて連結し、前後方向に伸縮して前記後側のレバーを作動させるように連結する左右一対の油圧シリンダを、走行機体における左右一対の前後長手のメインフレーム間に配置するように前記左右一対の昇降駆動手段を構成し、前記履帯式走行装置と走行機体との相対高さを検出するための左右各相対車高センサと、前記左右各油圧シリンダとを、それぞれリンク機構を介して連動連結させ、前記左右一対の相対車高センサは、脱穀装置の下面もしくは脱穀装置と穀粒タンクとの間に配置され、且つ前記メインフレームの部位であって、走行クローラの上面後部側にて脱穀装置の下面における一番流穀樋と二番流穀樋との間の山形状の隙間もしくは一番流穀樋とその前方位置の唐箕フアンとの間の山形状の隙間に配置されているものである。
【0009】
【発明の作用・効果】
前記請求項1に記載の発明の構成によれば、走行機体側に中途部を各々上下回動自在に枢支した前後一対のレバーの各アーム部を前記左右各履帯式走行装置におけるトラックフレームに各々枢着し、前後一対のレバーの上向き基部間を前後長手のロッド部材にて連結し、前後方向に伸縮して前記後側のレバーを作動させるように連結する左右一対の油圧シリンダを、走行機体における左右一対の前後長手のメインフレーム間に配置するように前記左右一対の昇降駆動手段を構成することにより、左右の昇降駆動手段を独立的に作動させることができ、圃場面の傾斜の如何に拘らず、履帯式走行装置と走行機体と相対車高を変更して走行機体の左右の傾斜角度を水平または任意の角度に保持するように制御できるものであり、そのときの相対車高を、前記左右一対の昇降駆動手段にそれぞれ独立的に関連させて構成した左右一対の相対車高センサによる検出結果にて感知することができる。
【0010】
そして、この左右一対の相対車高センサの配置箇所を、走行機体に搭載した脱穀装置の下面もしくは脱穀装置と穀粒タンクとの間に設定したから、左右一対の履帯の箇所から離れることになり、走行時に履帯にて走行機体下面方向に持ち運ばれた土や泥が相対車高センサに被さるという事態が少なくなり、当該相対車高センサが作動不良や故障するという事故がなくなるという効果を奏する。特に、脱穀装置の下面のうち、一番流穀樋と二番流穀樋との間もしくは一番流穀樋とその前方位置の唐箕フアンとの間は上下の凹凸部が存在するので、その凹凸の隙間を利用して相対車高センサを配置すると、別途に配置空間を確保する必要もなくなるという効果を奏する。
【0011】
また、昇降駆動手段としての左右各油圧シリンダのピストンロッドの前後方向移動量をリンク機構を介して各相対車高センサに伝達するのであるから、相対車高センサ自体は履帯式走行装置の昇降動に伴って動くことはない。従って、相対車高センサから制御装置に信号を伝達するための通信線も走行機体に固定して配線できるから、当該通信線が絶えず揺れ動くことがない。また、相対車高センサの配置箇所は、前述のように、走行機体の下面になるから、従来のように、走行機体の側面より外側に配置するに比べ、走行時に外部の物体、例えば圃場の穀稈等に触れるおそれがなく、これによっても相対車高センサが故障する原因を排除することができる。
さらに、左右一対の車高センサの配置箇所が、走行機体に搭載した脱穀装置の下面である上、前記左右一対の相対車高センサは、前記メインフレームの部位であって、走行クローラの上面後部側にて脱穀装置の下面における一番流穀樋と二番流穀樋との間の山形状の隙間もしくは一番流穀樋とその前方位置の唐箕フアンとの間の山形状の隙間に配置されているものであるから、履帯にて持ち上げられた泥や土が通信線に直接衝突することもないから、断線事故も防止できるという効果を奏する。
【0012】
【発明の実施の形態】
以下、本発明を具体化した実施形態について説明する。
図において、符号1はコンバインを示し、該コンバイン1は、走行機体2を支持する左右一対の履帯式(走行クローラ式)走行装置3,3と、前記走行機体2の上面に搭載した脱穀装置4と、前記走行機体2の前部に昇降動可能に装着した刈取前処理装置5とによって構成されている。
【0013】
前記一対の走行装置3,3は、左右一対の走行クローラ6と、これら両走行クローラ6の内部に配設した前後長手のトラックフレーム7とによって構成され、前記両走行クローラ6は、前記走行機体2に取付けしたミッションケース8から左右に突出するミッションファイナル9の先端における駆動用輪体10と、前記トラックフレーム7の後端部にテンション機構11を介して取付けた緊張用輪体12とに、各々巻掛けされ、また、前記トラックフレーム7には、前記クローラ6に対する複数個の接地用輪体13が取付けられていると共に、両端に接地用輪体14,15を備えた天秤型リンク16が、ピン軸17にて回動自在に枢着されている。
【0014】
前記走行機体2は、左右一対の前後長手の上下対のメインフレーム2a,2aと、その前部及び後部を横方向に連結するための断面下向きコ字状に形成した横部材18,19とからなり、前記左右の履帯式走行装置3,3を独立的に昇降駆動するための左右一対の昇降駆動手段は、走行機体2側に中途部を、支持軸20,21を介して各々上下回動自在に枢支した前後一対のベルクランクレバー27,29と、該前後両ベルクランクレバー27,29の上端側を前後に連結するロッド部材28と、走行機体2の前後方向に伸縮して前記後側のベルクランクレバー29,29を作動させる左右一対の油圧シリンダ31,32とにより構成する。
【0015】
即ち、側面視略L字状のベルクランクレバー27,29の中途部を、支持軸20,21を介して走行機体2側に装着するにあたり、前記両横部材18,19における先端が、前記走行クローラ6の内径側に突出するように設けて、この両横部材18,19内に、各々支持軸20,21を、当該各支持軸20,21が横部材18,19と平行に延びるように配設して、これら両支持軸20,21を、その両先端部における軸受体22,22及び中央部における軸受体24,24にて、各横部材18,19に対して着脱自在に取付ける一方、前記両横部材18,19のうち前部横部材18の両先端部に、前記ミッションケース8から突出するミッションファイナル9の先端部を、ブラケット25を介して着脱自在に取付けし、更に、前記両横部材18,19のうち後部横部材19の両先端部に、前記走行クローラ6の上側に対するガイド用のキャリアローラ26を取付ける。
【0016】
そして、前記ベルクランクレバー27,29の後向きの各アーム部を前記左右各履帯式走行装置におけるトラックフレーム7,7に各々ピン33,34を介して枢着する。
さらに、前記横部材18,19に穿設した孔35,36から、前後ベルクランクレバー27,29の上向き基部側を上向きに突出させ、この前後ベルクランクレバー27,29の上向き基部間を前後長手のロッド部材28にて連結する。他方、走行機体2の前後方向に伸縮して前記後側のベルクランクレバー29,29を作動させる左右一対の油圧シリンダ31,32を、走行機体2における左右一対の前後長手のメインフレーム2a,2a間に配置し、油圧シリンダ31,32のピストンロッド37,37に回動自在に連結した各々中間アーム38,38と、後ベルクランクレバー29,29の上向き基部とをピン軸39にて回動自在に連結する(図5及び図6参照)。このように構成すれば、走行機体2と高さ方向においてほぼ平行状に配置した油圧シリンダ31,32のピストンロッドを大きく突出させて、前後ベルクランクレバー27,29を大きく回動させ、走行機体2に対して履帯式走行装置3,3を大きく下向き移動させても、中間アーム38,38が後ベルクランクレバー29,29の上向き基部に対して屈曲回動して、油圧シリンダ31,32のほぼ水平姿勢が大きく変動せず、走行機体2上の上下隙間の小さい箇所に油圧シリンダを配置することができる。
【0017】
次に、図5及び図6を参照しながら、前記左右の履帯式走行装置3,3と走行機体2との相対高さを検出するための左右一対の相対車高センサ45,45の構成について説明する。図1及び図2に示すように、走行機体2の進行方向右側に前記脱穀装置4を、左側に穀粒タンク40を配置し、穀粒タンク40の前側には運転室41が設けられている。そして、脱穀装置4で脱穀された穀粒(籾等)を穀粒タンク40に一時貯留し、所定量積載されると、放出オーガ42を介して外部の運搬車等に放出する。この放出オーガ42の横向き筒は図示しない回動駆動アクチェータにて水平方向及び上下方向に回動するようになっている。
【0018】
前記回動式のポテンショメータからなる左右一対の相対車高センサ45,45は、脱穀装置4の下面もしくは前記穀粒タンク40と脱穀装置4との間であって、走行機体2との上下隙間内に配置されるものあり、具体的には走行機体2における前後長手の左右一対のメインフレーム2a,2aの後部寄り部位で、走行クローラ6,6の上面後部側にて脱穀装置4における一番流穀樋43と二番流穀樋44との間の山形状の隙間46に配置される。なお、一番流穀樋43とその前方位置の唐箕フアンとの間の山形状の隙間に配置しても良い。
【0019】
その構成をさらに詳述すると、前記隙間46の下方には、前記左右一対のメインフレーム2a,2aの間を連結する断面下向きコ字状の支持板47をボルト等にて固定し、その上側に左右一対の相対車高センサ45,45を固定し、後述するそれぞれのリンク機構56,56を介して連動連結するものである。
即ち、このリンク機構56,56は、前記支持板47の下面側にはそれぞれ一対の軸受48‥‥にて両端を回転自在に軸支された作動軸49,50が配置され、該各作動軸49,50の一端に下向きに突設した第1アーム51,51と前記各後ベルクランクレバー29,29の上向き基部側のピン軸39とを前後長手の連結ロッド52,52にてピン連結する一方、各作動軸49,50の他端に突設する第2アーム53,53の先端と、各相対車高センサ45,45の回動アーム54,54とを縦ロッド55,55にてピン連結することにより構成されている。この場合、各第2アーム53及び縦ロッド55が移動可能ならしめるために前記支持板47に抜き孔(図示せず)が穿設されている。また、前記支持板47のほぼ全長にわたって着脱自在に覆うカバー体57により前記相対車高センサ45,45に土や泥が被らないようにしている。
【0020】
この構成により、図5から明らかなように、各油圧シリンダ31(32)のピストンロッド37を(走行機体2の後方に)突出動させると、中間アーム38を介して後ベルクランクレバー29の先端側は下向き回動し(図5の実線状態参照)、トラックフレーム7は走行機体2から下方に離れ、走行機体2と履帯式走行装置3の下面との相対高さは大きくなり、走行機体2は圃場面に対して高くなる。このとき、連結ロッド52は後移動し、第1アーム51、作動軸49(50)、第2アーム53及び縦ロッド55を介して相対車高センサ45の回動アーム54は図5において反時計方向に回動する。
【0021】
前記と逆に、各油圧シリンダ31(32)のピストンロッド37を(走行機体2の前方に)後退動させると、中間アーム38を介して後ベルクランクレバー29の先端側は上向き回動し(図5の二点鎖線状態参照)、トラックフレーム7は走行機体2に対して接近し、走行機体2と履帯式走行装置3の下面との相対高さは小さくなり、走行機体2は圃場面に対して低くなる。この場合には、連結ロッド52は前移動するので、相対車高センサ45の回動アーム54は、図5において二点鎖線で示すように、時計方向に回動することになる。
【0022】
このように、左右の昇降駆動手段によって、左右を各々単独で、その前後一対の両ベルクランクレバー27,29を一斉に揺動回動することにより、トラックフレーム7を、走行機体2に対して上下動することができるから、走行機体2の高さの調節、及び走行機体2の左右傾斜の調節を行うことができると共に、左右それぞれの油圧シリンダ31,32の伸縮量に関連させて相対車高センサ45,45を作動させることにより、走行機体2の左右に対する左右の走行装置3,3の相対高さを検出できるのである。
【0023】
なお、図7に示すように、運転室41内の操作パネル部60には、走行機体2の左右の相対車高の平均値で設定するためのボリューム式の車高設定器61と、水平面に対する走行機体2の左右傾斜角度を設定するためのボリューム式の傾斜角度設定器62と各種の表示パネル63,64,65と、手動操作により車高及び左右傾斜を調節するための十字方向傾動型手動レバー66と、刈取り脱穀作業・走行等のための作業操作レバー67等を備え、走行機体2の左右操向は丸ハンドル68にて実行する。また、前記車高設定器61は、その摘みを所定角度にセットすると、車高をその設定した目標値になるように、図8のマイクロコンピュータ式の制御装置70によって自動制御され、摘みを零位置にセットするとその自動制御がOFF状態となる。なお、十字方向傾動型手動レバー66を傾動すると、その動きによる作業指令が優先されるように、車高自動制御はONからOFFに切り替わる。
【0024】
制御装置70には、各種演算処理を実行するCPU、このCPUにて演算処理するのに必要な各種制御プログラムや初期値を予め記憶させたROM(読み出し専用メモリ)、演算処理を実行するのに用いられる各種データ(検出値、設定値等)を一時的に記憶するためのRAM(随時読み書き可能メモリ)、インターフェイス等を備える。
【0025】
制御装置70の入力インターフェイスには、刈取・脱穀を開始するときその駆動伝達クラッチ(図示せず)をONするための脱穀スイッチ71と、前記車高設定器61と、傾斜角度設定器62と、前記操作パネル部60内等に配置された静電容量式等の傾斜センサ72と、前記左右一対の相対車高センサ45,45と、超音波式の対地高さセンサ73等を接続する。傾斜センサ72は、水平に対する走行機体2の左右方向の傾斜角度を検出するものであり、前記傾斜角度設定器62による設定値と比較に基づき、走行機体2の左右傾斜を水平もしくは任意の傾斜角度に保持するべく、左右の油圧シリンダ31,32に対する各電磁制御弁74,75の電磁ソレノイド74a,74b(75a,75b)を作動させるのに用いる。
【0026】
また、前記車高設定器61により設定された相対車高(左右の履帯式走行装置3,3の走行機体2に対する平均高さ)の情報を制御装置70に入力すると、前記傾斜角度設定器62の設定値に基づく左右傾斜の状態にて、目標(設定)の相対車高になるように、左右の油圧シリンダ31,32に対する各電磁制御弁74,75の電磁ソレノイド74a,74b(75a,75b)を作動させる。この場合、この昇降制御中、前記左右傾斜の制御は保持される。
【0027】
なお、対地高さセンサ73は刈取前処理装置5における下面前部等に圃場面(下面)に向けて配置され、刈取前処理装置5による穀稈の刈高さを制御する場合に、図示しない刈高さ設定器で予め設定された高さに刈取前処理装置5における刈刃が位置するように図示しない昇降用油圧シリンダの作動を制御するためのものである。
【0028】
従って、圃場内にコンバインを乗り入れて脱穀クラッチをオンにして刈取脱穀作業を開始するに際して、圃場が湿田のように軟弱地であるときには、一方または左右双方の走行クローラ6箇所だけが地面にめり込み、圃場面と走行機体2の下面との対地高さは相対的に低くなるので、前記車高設定器61により設定された相対車高を比較高い値に設定することが好ましい。
【0029】
また、穀粒タンク40内に穀粒が多く積載されたときには、穀粒タンク40がある走行機体2の右側が沈み込み安くなるので、車高設定器61や傾斜角度設定器62による設定値を変更して走行機体の重心の偏在に伴う当該走行機体の左右傾斜姿勢を安定方向に変更することが好ましい。
そして、前記左右一対の相対車高センサ45,45の配置箇所を、走行機体2に搭載した脱穀装置4の下面もしくは脱穀装置4と穀粒タンク40との間に設定したから、左右一対の走行クローラ6,6の箇所から離れることになり、走行時に履帯にて走行機体2下面方向に持ち運ばれた土や泥が相対車高センサ45,45に被さるという事態が少なくなり、当該相対車高センサ45,45が作動不良や故障するという事故がなくなるという効果を奏する。特に、脱穀装置4の下面側は、一番流穀樋43と二番流穀樋44との間等上下の凹凸部が存在するので、その凹凸の隙間を利用して相対車高センサ45,45を配置すると、別途に配置空間を確保する必要もなくなるという効果を奏する。
【0030】
また、相対車高センサ45,45の配置箇所は、前述のように、走行機体2の下面になるから、従来のように、走行機体2の側面より外側に配置するに比べ、走行時に外部の物体、例えば圃場の穀稈等に触れるおそれがなく、これによっても相対車高センサ45,45が故障する原因を排除することができる。
さらに、左右一対の相対車高センサ45,45の配置箇所が、走行機体2に搭載した脱穀装置4の下面もしくは脱穀装置4と穀粒タンク40との間である上、昇降駆動手段としての左右各油圧シリンダ31,32のピストンロッド前後方向伸縮量をリンク機構56,56を介して各相対車高センサ45に伝達するのであるから、相対車高センサ45,45自体は履帯式走行装置3の昇降動に伴って動くことはない。従って、相対車高センサ45,45から制御装置70に信号を伝達するための通信線も走行機体2に固定して配線できるから、当該通信線が絶えず揺れ動くことがなく、また、履帯にて持ち上げられた泥や土が通信線に直接衝突することもないから、断線事故も防止できるという効果を奏する。

And it can be sensed by independently related to not detect by a pair of left and right relative vehicle height sensor which is constructed by the result to the pair of right and left lift driving means.
[0010]
And since the arrangement | positioning location of this pair of left and right relative vehicle height sensors was set between the lower surface of the threshing device mounted on the traveling machine body or between the threshing device and the grain tank, it would be separated from the location of the pair of left and right crawler belts. , The situation that dirt and mud carried by the crawler belt in the direction of the lower surface of the traveling body is covered with the relative vehicle height sensor is reduced, and the accident that the relative vehicle height sensor malfunctions or breaks down is produced. . In particular, there are upper and lower irregularities between the first and second cereal cocoons or between the first and second cereal cocoons in the lower surface of the threshing device. If the relative vehicle height sensor is arranged by using the uneven gap, it is not necessary to separately secure the arrangement space.
[0011]
In addition, since the longitudinal movement amount of the piston rod of each of the left and right hydraulic cylinders as the lifting drive means is transmitted to each relative vehicle height sensor via the link mechanism, the relative vehicle height sensor itself moves up and down the crawler type traveling device. It will not move with. Accordingly, since a communication line for transmitting a signal from the relative vehicle height sensor to the control device can be fixed and wired to the traveling machine body, the communication line does not constantly move. Also, since the relative vehicle height sensor is disposed on the lower surface of the traveling machine body as described above, an external object such as a farm field when traveling is compared to the conventional arrangement outside the side surface of the traveling machine body. There is no risk of touching the cereal and the like, and this can also eliminate the cause of the relative vehicle height sensor malfunctioning.
Further, the arrangement position of the pair of left and right vehicle height sensors is the lower surface of the threshing device mounted on the traveling machine body, and the pair of left and right relative vehicle height sensors are parts of the main frame, and the upper rear portion of the traveling crawler Arranged in the mountain-shaped gap between the first and second-class cereals on the lower side of the threshing device or on the side, the mountain-shaped gap between the first-type cereals and the tang fang Since mud and soil lifted by the crawler track do not directly collide with the communication line, it is possible to prevent a disconnection accident.

The pin shaft 17 is pivotably mounted.
[0014]
The traveling machine body 2 includes a pair of left and right mainframes 2a and 2a having a longitudinal front and rear, and lateral members 18 and 19 formed in a U-shaped cross section downward to connect the front and rear portions in the lateral direction. The pair of left and right elevating drive means for independently elevating and lowering the left and right crawler type traveling devices 3 and 3 are respectively turned up and down via the support shafts 20 and 21 in the middle of the traveling machine body 2 side. A pair of front and rear bell crank levers 27 and 29 pivoted freely, a rod member 28 for connecting the upper end sides of the front and rear bell crank levers 27 and 29 back and forth, and the rear and rear of the traveling machine body 2 are expanded and contracted. It comprises a pair of left and right hydraulic cylinders 31 and 32 that actuate the bell crank levers 29 and 29 on the side.
[0015]
That is, when the middle portions of the bell crank levers 27 and 29 having a substantially L shape in side view are attached to the traveling machine body 2 via the support shafts 20 and 21, the distal ends of the lateral members 18 and 19 It is provided so as to protrude toward the inner diameter side of the crawler 6, and the support shafts 20 and 21 are respectively provided in the lateral members 18 and 19 so that the support shafts 20 and 21 extend in parallel with the lateral members 18 and 19. The two support shafts 20 and 21 are detachably attached to the lateral members 18 and 19 at the bearing bodies 22 and 22 at both ends and the bearing bodies 24 and 24 at the center. The tip of the mission final 9 projecting from the mission case 8 is detachably attached to both tips of the front transverse member 18 of the transverse members 18, 19, via a bracket 25, and Both side members The both ends of the rear lateral member 19 of the 8 and 19, attaching the carrier roller 26 of the guide relative to the upper side of the traveling crawler 6.
[0016]
Then, the rearward arm portions of the bell crank levers 27 and 29 are pivotally attached to the track frames 7 and 7 in the left and right crawler type traveling devices via pins 33 and 34, respectively.
Further, the upward base portions of the front and rear bell crank levers 27 and 29 protrude upward from the holes 35 and 36 formed in the lateral members 18 and 19, and the front and rear bell crank levers 27 and 29 extend longitudinally between the upward base portions. The rod member 28 is connected. On the other hand, a pair of left and right hydraulic cylinders 31 and 32 for operating the rear bell crank levers 29 and 29 by extending and contracting in the front and rear direction of the traveling machine body 2 are paired with a pair of left and right longitudinal main frames 2a and 2a in the traveling machine body 2. The intermediate arms 38 and 38 that are disposed between the piston rods 37 and 37 of the hydraulic cylinders 31 and 32 and are pivotally connected to each other and the upward base portions of the rear bell crank levers 29 and 29 are rotated by the pin shaft 39. Connect freely (see FIGS. 5 and 6). If comprised in this way, the piston rod of the hydraulic cylinders 31 and 32 arrange | positioned substantially parallel with the traveling body 2 in the height direction will be protruded largely, the front and rear bell crank levers 27 and 29 will be rotated largely, and a traveling body will be carried out. 2, even if the crawler type traveling devices 3, 3 are largely moved downward, the intermediate arms 38, 38 bend and rotate with respect to the upward bases of the rear bell crank levers 29, 29, The hydraulic posture can be arranged at a location where the vertical gap on the traveling machine body 2 is small, with the horizontal posture substantially not fluctuating.
[0017]
Next, with reference to FIGS. 5 and 6, the configuration of a pair of left and right relative vehicle height sensors 45, 45 for detecting the relative height between the left and right crawler type traveling devices 3, 3 and the traveling machine body 2. explain. As shown in FIGS. 1 and 2, the threshing device 4 is disposed on the right side of the traveling direction of the traveling machine body 2, the grain tank 40 is disposed on the left side, and a cab 41 is provided on the front side of the grain tank 40. . Then, the grains (such as straw) threshed by the threshing device 4 are temporarily stored in the grain tank 40 and, when loaded in a predetermined amount, are discharged to an external transport vehicle or the like via the discharge auger 42. The horizontal tube of the discharge auger 42 is rotated in the horizontal direction and the vertical direction by a rotation drive actuator (not shown).
[0018]
A pair of left and right relative vehicle height sensors 45, 45 composed of the rotary potentiometer are located between the lower surface of the threshing device 4 or between the grain tank 40 and the threshing device 4 and in the vertical gap with the traveling machine body 2. Specifically, in the traveling machine body 2, at the rear portion of the pair of left and right main frames 2 a, 2 a in the longitudinal direction, the most current in the threshing device 4 on the upper rear side of the traveling crawlers 6, 6. It is arranged in a mountain-shaped gap 46 between the cereal basket 43 and the second style cereal basket 44. In addition, you may arrange | position in the mountain-shaped clearance gap between the most cereal mash 43 and the Kara Juan of the front position.
[0019]
The configuration will be described in further detail. Below the gap 46, a supporting plate 47 having a U-shaped cross section that connects the pair of left and right main frames 2a, 2a is fixed with a bolt or the like, and above that A pair of left and right relative vehicle height sensors 45, 45 are fixed and interlocked via respective link mechanisms 56, 56 described later.
In other words, the link mechanisms 56 and 56 are provided with operating shafts 49 and 50 that are rotatably supported at both ends by a pair of bearings 48 on the lower surface side of the support plate 47, respectively. First arms 51, 51 projecting downward at one end of 49, 50 and pin shaft 39 on the upper base side of each of the rear bell crank levers 29, 29 are pin-connected by longitudinal connecting rods 52, 52. On the other hand, the tips of the second arms 53 and 53 projecting from the other ends of the operating shafts 49 and 50 and the rotating arms 54 and 54 of the relative vehicle height sensors 45 and 45 are pinned by vertical rods 55 and 55, respectively. It is configured by connecting. In this case, a hole (not shown) is formed in the support plate 47 so that each second arm 53 and the vertical rod 55 can move. Further, a cover body 57 that detachably covers almost the entire length of the support plate 47 prevents the relative vehicle height sensors 45, 45 from being covered with soil or mud.
[0020]
With this configuration, as is apparent from FIG. 5, when the piston rod 37 of each hydraulic cylinder 31 (32) protrudes (rearward the traveling machine body 2), the tip of the rear bell crank lever 29 is interposed via the intermediate arm 38. The track frame 7 moves downward from the traveling machine body 2 and the relative height between the traveling machine body 2 and the lower surface of the crawler-type traveling device 3 is increased. Is higher than the farm scene. At this time, the connecting rod 52 moves backward, and the rotating arm 54 of the relative vehicle height sensor 45 is counterclockwise in FIG. 5 via the first arm 51, the operating shaft 49 (50), the second arm 53, and the vertical rod 55. Rotate in the direction.
[0021]
Contrary to the above, when the piston rod 37 of each hydraulic cylinder 31 (32) is moved backward (in front of the traveling machine body 2), the front end side of the rear bell crank lever 29 is rotated upward via the intermediate arm 38 ( 5), the track frame 7 approaches the traveling machine body 2, the relative height between the traveling machine body 2 and the lower surface of the crawler-type traveling device 3 is reduced, and the traveling machine body 2 is in a field scene. On the other hand, it becomes lower. In this case, since the connecting rod 52 moves forward, the rotating arm 54 of the relative vehicle height sensor 45 rotates clockwise as indicated by a two-dot chain line in FIG.
[0022]
In this way, the left and right lifting and lowering drive means independently swing the left and right pair of bell crank levers 27 and 29 all at once, thereby allowing the track frame 7 to move relative to the traveling machine body 2. Since it can move up and down, it is possible to adjust the height of the traveling machine body 2 and the left and right inclination of the traveling machine body 2 and to adjust the relative vehicle in relation to the expansion and contraction amounts of the left and right hydraulic cylinders 31 and 32. By operating the height sensors 45, 45, it is possible to detect the relative height of the left and right traveling devices 3, 3 with respect to the left and right of the traveling machine body 2.
[0023]
As shown in FIG. 7, the operation panel 60 in the cab 41 has a volume type vehicle height setting device 61 for setting an average value of the left and right relative vehicle heights of the traveling machine body 2 and a horizontal plane. A volume-type tilt angle setting device 62 for setting the left and right tilt angle of the traveling machine body 2 and various display panels 63, 64, 65, and a cross-direction tilt type manual for manually adjusting the vehicle height and left / right tilt. A lever 66 and a work operation lever 67 for cutting / threshing / running and the like are provided, and the left and right steering of the traveling machine body 2 is executed by a round handle 68. The vehicle height setting device 61 is automatically controlled by the microcomputer-type control device 70 of FIG. 8 so that the vehicle height becomes the set target value when the knob is set at a predetermined angle. When set to the position, the automatic control is turned off. Note that when the cross-direction tilt type manual lever 66 is tilted, the vehicle height automatic control is switched from ON to OFF so that a work command based on the movement is prioritized.
[0024]
The control device 70 includes a CPU that executes various arithmetic processes, various control programs and ROM (read only memory) in which initial values are stored in advance, and an arithmetic process. It includes a RAM (memory that can be read and written as needed), an interface, and the like for temporarily storing various data used (detection values, setting values, etc.).
[0025]
The input interface of the control device 70 includes a threshing switch 71 for turning on its drive transmission clutch (not shown) when cutting and threshing are started, the vehicle height setting device 61, an inclination angle setting device 62, A capacitance type inclination sensor 72 arranged in the operation panel 60 or the like, the pair of left and right relative vehicle height sensors 45, 45, an ultrasonic type ground height sensor 73 and the like are connected. The tilt sensor 72 detects the tilt angle in the left-right direction of the traveling machine body 2 with respect to the horizontal, and the horizontal tilt of the traveling machine body 2 is set to a horizontal or arbitrary tilt angle based on comparison with the set value by the tilt angle setting unit 62. The electromagnetic solenoids 74a and 74b (75a and 75b) of the electromagnetic control valves 74 and 75 with respect to the left and right hydraulic cylinders 31 and 32 are used to operate the cylinders.
[0026]
Further, when information on the relative vehicle height (average height of the left and right crawler type traveling devices 3 and 3 with respect to the traveling machine body 2) set by the vehicle height setting device 61 is input to the control device 70, the inclination angle setting device 62 is provided. Electromagnetic solenoids 74a and 74b (75a and 75b) of the electromagnetic control valves 74 and 75 for the left and right hydraulic cylinders 31 and 32 so that the target (set) relative vehicle height is obtained in a state of tilting left and right based on the set value. ). In this case, the left / right tilt control is maintained during the elevation control.
[0027]
The ground height sensor 73 is arranged on the front surface of the lower surface of the pre-cutting processing device 5 toward the field scene (lower surface), and is not shown when controlling the cutting height of the cereal by the pre-cutting processing device 5. This is for controlling the operation of a lifting hydraulic cylinder (not shown) so that the cutting blade in the pre-cutting processing device 5 is positioned at a height set in advance by a cutting height setting device.
[0028]
Therefore, when the combine is put into the field and the threshing clutch is turned on to start the harvesting and threshing work, when the field is a soft ground such as a wet field, only one or both of the traveling crawlers on both the left and right sides sink into the ground, Since the ground height between the farm scene and the lower surface of the traveling machine body 2 is relatively low, it is preferable to set the relative vehicle height set by the vehicle height setting device 61 to a relatively high value.
[0029]
Further, when a large amount of grains are loaded in the grain tank 40, the right side of the traveling machine body 2 where the grain tank 40 is located sinks and becomes cheap, so the set values by the vehicle height setting device 61 and the inclination angle setting device 62 are set. It is preferable to change and change the right-and-left inclined posture of the traveling machine body according to the uneven distribution of the center of gravity of the traveling machine body in a stable direction.
And since the arrangement | positioning location of the said left-right pair of relative vehicle height sensors 45 and 45 was set between the lower surface of the threshing apparatus 4 mounted in the traveling body 2, or between the threshing apparatus 4 and the grain tank 40, a pair of left-right driving | running | working The situation where the crawlers 6 and 6 are separated from each other and the soil and mud carried by the crawler belt toward the lower surface of the traveling machine body 2 during traveling is less likely to cover the relative vehicle height sensors 45 and 45, and the relative vehicle height. There is an effect that there is no accident that the sensors 45 and 45 malfunction or fail. In particular, since the lower surface side of the threshing device 4 has upper and lower uneven portions such as between the first and second cereal rice bran 43, 44, the relative vehicle height sensor 45, When 45 is arranged, there is an effect that it is not necessary to separately secure an arrangement space.
[0030]
Since the relative vehicle height sensors 45 and 45 are disposed on the lower surface of the traveling machine body 2 as described above, the relative vehicle height sensors 45 and 45 are disposed outside the side surface of the traveling machine body 2 as in the prior art. There is no risk of touching an object, for example, a grain basket in the field, and this can also eliminate the cause of the failure of the relative vehicle height sensors 45, 45.
Further, the arrangement position of the pair of left and right relative vehicle height sensors 45, 45 is between the lower surface of the threshing device 4 mounted on the traveling machine body 2 or between the threshing device 4 and the grain tank 40, and the left and right as lifting drive means. The amount of expansion and contraction in the longitudinal direction of the piston rod of each hydraulic cylinder 31, 32 is transmitted to each relative vehicle height sensor 45 via the link mechanisms 56, 56, so the relative vehicle height sensors 45, 45 themselves are the crawler type traveling device 3. It does not move with the up and down movement. Accordingly, since the communication line for transmitting a signal from the relative vehicle height sensors 45, 45 to the control device 70 can also be fixed and wired to the traveling machine body 2, the communication line does not constantly move and is lifted by the crawler belt. Since the mud and soil that are collected do not directly collide with the communication line, the disconnection accident can be prevented.
