【０００３】
【発明が解決しようとする課題】
然し乍ら、機体の左右旋回、刈取部の引起し装置の変速操作を容易にすると、作業者の労力が軽減し作業能率の向上を図れる。
【０００４】
【課題を解決するための手段】
この発明は、このような課題を解決するコンバインにおける運転装置を提供するものであって、つぎのような技術的手段を講じた。
すなわち、走行装置（１）を具備する車台の前部に刈取部（２）を設け、該刈取部（２）の後方に脱穀部（３）と穀粒を貯溜するタンク（４）とを横方向に並設し、該タンク（４）の前方に設けた座席（５）の左横側部に変速レバ−（６）及び左側操作パネル（３５）を有する左側操作壁（７）を設けると共に、座席（５）の前側部には、前側操作パネル（５１）を有する前側操作壁（９）を設け、前記左側操作壁（７）と前側操作壁（９）により形成されるコーナー部における前記左側操作パネル（３５）の前端部に、内側を低く外側を高くして座席（５）と対向するように計器パネル（３６）を設け、該計器パネル（３６）は、前記変速レバー（６）を最も前側位置に位置させたときにおいても、座席（５）に着座した運転者が目視可能な位置に設ける構成とし、前記前側操作壁（９）と前側操作パネル（５１）は、機体の前進方向における平面視において、左側操作壁（７）から乗降側に向かって後方に向けて階段状に形成し、前側操作壁（９）の幅の最も広い右側端部に操作レバ−（８）を設け、前側操作壁（９）の幅の最も狭い位置に位置する左側のフロア（６９）上に駐車ブレーキペダル（７０）を設け、前記操作レバ−（８）の握り部（５９）上面の同一面には刈取部（２）の引き起し装置（１７）の速度を高速にする指操作可能なスイッチ（Ｓｇ）と引き起し装置（１７）の速度を低速にする指操作可能なスイッチ（Ｓｈ）とを上下間隔を置いて配置する構成にすると共に、機体の左右旋回を選択する指操作可能なスイッチ（Ｓｅ），（Ｓｆ）を左右間隔を置いて配置して構成し、前記操作レバー（８）を手で握った状態で該操作レバー（８）を操作しながら、指で前記スイッチ（Ｓｅ），（Ｓｆ）及びスイッチ（Ｓｇ），（Ｓｈ）を操作可能に構成したことを特徴とするコンバインとする。
【０００５】
【作用】
運転者は運転部の座席５部で機体の回転各部を駆動し、変速レバ−６、操作レバ−８等を操作して機体を前進させ作業を開始する。すると、刈取部２で刈り取られて後方に搬送された稲は、脱穀部３で脱穀処理され、そして、脱粒した籾は脱穀部３からタンク４に送られ、その後機外に排出される。運転者が、例えば条合わせを行う場合には、立ち上がって前側操作壁９に近接した姿勢になる。そして、スイッチＳｇを指で操作すると、刈取部２の引起し装置１７が高速状態に変速される。また、スイッチＳｈを指で操作すると、刈取部２の引起し装置１７が低速状態に変速される。また、スイッチＳｅ，Ｓｆを指で操作すると、機体が左右旋回する。さらに、操作レバー８を左右方向に傾倒しても機体が左右旋回する。操作レバー８を前後に傾倒すると刈取部２が昇降する。
【０００６】
【効果】
指の操作でスイッチＳｇ，Ｓｈを指で操作すると、刈取部２の引起し装置１７が高低速に変速される。指の操作でスイッチＳｅ，Ｓｆを指で操作すると、機体が左右旋回し、さらに、操作レバー８を左右方向に傾倒しても機体が左右旋回する。また、操作レバー８を前後方向に傾倒すると刈取部２が昇降する。したがって、作業者の労力が軽減し作業能率が向上するようになる。
【０００７】
【発明の実施の形態】
以下、本発明の実施の一形態を図面に基づいて具体的に説明する。
まず、その構成について説明すると、コンバイン１１は、機体の前進方向に向かって、左右方向に所定の間隔を置いて配置した走行装置１を具備する車台１２の前部に油圧式の昇降手段によって昇降自在に刈取部（実施例では３条刈り）２を設け、該刈取部２の後方で車台１２の左側部に脱穀部３を設け、該脱穀部３の右側部にタンク４を設け、該タンク４と刈取部２との間の空間部にエアコン１３を有するキャビン１４によって囲まれた運転部１０を設けている。
【０００８】
該走行装置１はクロ−ラ型であるが、車輪又は車輪とクロ−ラとの組合わせによる構成としてもよい。
刈取部２は左右横方向に複数個配置した分草体１５と、後方斜め上方に移動する引き起こしラグ１６を有し横方向に複数個配置した引き起こし装置１７と、バリカン型の刈取装置１８と、刈取った穀稈を後方上方に搬送する刈取穀稈搬送装置１９とを一体に構成している。なお、刈取部２への駆動部に、例えばＨＳＴのような変速手段（有段、無段いずれでもよい）を設けている。また、引き起こし装置１７への駆動部に、例えばＨＳＴのような変速手段（有段、無段いずれでもよい）を設けることもできる。
【０００９】
脱穀部３は機体の進行方向に回転する穀稈自動送り込み装置２０を一側部に有し、前記刈取穀稈搬送装置１９が搬送してきた穀稈の株元部を挟持後搬送して穂先部を扱室内に送り込み脱穀する自脱型の構成である。
タンク４は中空に形成したタンクで底部に下部螺旋（図示せず）を有し、前記脱穀部３の揚穀装置（図示せず）によって上方に搬送された穀粒を一時収容すると共に、横側方に回動自在に設けている。そして、該下部螺旋の搬送終端部はタンク４の後方に軸芯を縦方向に位置した縦揚穀装置２１の下端部に連通し、また、該縦揚穀装置２１の上端部は、排出口が上下及び左右方向に回動する排出オ−ガ２２に連通している。
【００１０】
キャビン１４は枠組みしたフレ−ム２３の前部と横側部に夫れ夫れ透明の板を有する窓２４を設け、機体フレ−ム２５に着脱自在に取付けている。そして、該キャビン１４の右側部に、後部を回動具（例えば蝶板）２６を介して開閉自在に取り付けたドア２７を設けている。２８は外面に防塵吸気網２９を設けたエンジンル−ムカバ−であって、機体フレ−ム２５に回動具（例えば蝶板）３０を介して横方向に回動自在に取り付けている。３１は前記脱穀部３の扱胴カバ−３２の上面に着脱自在に設けたエアコン１３のコンデンサである。
【００１１】
運転部１０は座席５と、機体の前進方向に向かって背もたれ３４を有する座席５の左横側部で且つ座席５よりも上部に一体に設けた左側操作パネル３５を上方に位置する左側操作壁７を立設し、その前側部に前側操作壁９を立設し、平面視において、左側操作壁７と前側操作壁９はＬ字型に配置している。そして、該左側操作壁７と前側操作壁９により形成したコ−ナ−部における左側操作パネル３５の前端部に、内側を低く外側（コ−ナ−側）を高くして座席５対向するように斜めに設けていると共に回転表示具３７、タンク４に収容している籾量を表示する籾量表示具３８、燃料表示具３９等を有する計器パネル３６を設けている。従って、該計器パネル３６に設けている回転表示具３７、籾量表示具３８、燃料表示具３９等も座席５に座った運転者が見え易いように斜めに位置する。
【００１２】
４０と４１は横方向に並設した変速ガイド溝及び副変速ガイド溝であり、４２と４３と４４はガイド溝４０，４１の後方で且つ横方向に並設した脱穀レバ−ガイド溝，刈取ガイド溝，スピン・マイルド切り替えガイド溝であり、左操作パネル３５に設けている。そして、該変速ガイド溝４０に車速を変速する変速レバ−（ＨＳＴレバ−）６を、副変速ガイド溝４１に車速を副変速する副変速レバ−４５を、脱穀レバ−ガイド溝４２に脱穀部３への動力を入り切りする脱穀レバ−４６を、刈取ガイド溝４３に刈取部２への動力を入り切りする刈取レバ−４７、スピン・マイルド切り替えガイド溝にスピンまたはマイルドタ−ン走行に切り替えるスピン・マイルド切り替えレバ−４８を夫れ夫れ前後方向に回動自在に設けている。
【００１３】
また、左側操作壁７の右側（内側）に形成した斜面部の前部に、スロットルレバ−ガイド溝４９を前後方向に形成し、このスロットルレバ−ガイド溝４９に沿ってエンジンの回転数を調節するスロットルレバ−５０を回動自在に設けている。なお、前記計器パネル３６は変速レバ−６を最前（最高速）側に回動したときにおいても、座席５に座った運転者が計器パネル３６の各表示具３７，３８，３９を目視し得る位置に設けている。従って、運転者は機体各部の異常有無などの運転状況を容易に把握できる。
【００１４】
前側操作壁９は上部に前側操作パネル５１を着脱自在に設けており、運転者はこの前側操作壁９と座席５との間を通って右側から乗降する構成としている。そして、該前側操作壁９と前側操作パネル５１は、機体の前進方向における平面視において、左側操作壁側から乗降側に向かって後方に向けて階段上に形成しており、コ−ナ−部寄りが前後方向の幅が最も小さい。そして、該前側操作パネル５１の前後幅が小さいところにブザ−停止スイッチ５２、表示切り替えスイッチ５３、作業灯スイッチ５４等を設け、中間部にウインカ及びホ−ンスイッチ５５、キ−スイッチ５６等を設け、幅の最も広い右側端部に操作レバ−８を設けている。
【００１５】
操作レバ−８は前後に傾倒すると刈取部２を昇降し、左右に傾倒すると機体の進行方向を変更する構成であり、昇降や進行方向の変更の切り替えを検出するスイッチ（図示せず）を入り切りし且つ上端が座席側（運転者側）に位置するように斜めに突出するレバ−５８、レバ−５８の上端部に設けた握り具５９、レバ−５８の中間部から下部を覆う可撓性（合成樹脂製のゴム、ウレタン等）のカバ−５９等を設けている。
【００１６】
そして、該操作レバ-８の傾倒により入り切りするスイッチは、リミットスイチのような接触式、光電スイッチのような非接触式、ポテンショメ−タや差動トランスでもよく、例えば、入りになると、マイクロコンピュ−タのＣＰＵからの指令信号によりアクチュエ−タを作動して、油圧シリンダ等の伸縮により刈取部２の昇降、操向クラッチやブレ−キの入切により機体の進行方向を変更する構成である。
【００１７】
前記握り部５９の上面には、横方向及び縦方向に間隔を置いて、指操作できるボタンスイッチＳ１，Ｓ２，Ｓ３，Ｓ４を設けている。該横方向に配置したボタンスイッチの中で、Ｓ１を指で押すことにより前記操向クラッチを切りにして機体の進行方向を緩やかに左旋回（左緩旋回）し、Ｓ２を指で押すことにより前記操向クラッチを切りにして機体の進行方向を緩やかに右旋回（右緩旋回）する。
【００１８】
縦方向に配置したボタンスイッチの中で、Ｓ３を指で押すことによりアクチュエ−タにより刈取部２を上昇し、Ｓ４を指で押すことによりアクチュエ−タにより刈取部２を下降する。なお、該スイッチＳ３，４を入りにすることにより、ＣＰＵから所定時間作動信号を出力し、刈取部２を所定高さに自動的に調節する。
該カバ−５９は上部よりも下部を大きくしたラッパ状に形成すると共に、この下端部に矩形（実施例では、略正方形）の上カバ−体６０と各角部に孔６８を有する下カバ−体６１とを上下に間隔を置いてこの各カバ−体６０，６１よりも幅が小さい接続体６２により一体に設けている。
【００１９】
６３は前側操作パネル５１に切り欠いた孔、６４は平面視において前記カバ−体６０，６１の外端縁よりも内側に位置し、各角部の裏面にナット６５を取り付けた固定板、６６はナット６５に対向する位置で前側操作パネル５１に設けた孔、６７はネジである。
カバ−５９を前側操作パネル５１に取り付けるには、下カバ−体６１を孔６３を通して前側操作パネル５１の下側に入れ、下カバ−６１の下側に固定板６４を置く。そして、ネジ６７を孔６６，６８を通してナット６５に締め付けると、下カバ−体６１は前側操作パネル５１の裏面と固定板６４によって挟まれ固定される。このとき、角部に位置するネジ６７は上カバ−体６０によって覆われるので、このネジ６７をカバ−するための別の部材を必要とせず安価にできる。
【００２０】
駐車ブレ−キペダル７０は前側操作パネル５１のコ−ナ−部側における前記運転部１０の底部に設けたフロア６９を通って上方後方に突出させて設けている。
つぎに、その作用について説明する。
まず、運転者はキャビン１４のドア２７を開閉して座席５に座り、駐車ブレ−キペダル７０を踏み込んでキ−をキ−スイッチ５６に入れエンジンを起動すると、エンジンから出力された動力は伝動機構を介して機体の回転各部に伝動される。
【００２１】
そして、スロットルレバ−５０を回動してエンジンを所定回転数に選択すると共に、副変速レバ−４５を前側に回動して、例えば標準を選択し、さらに脱穀レバ−４６及び刈取レバ−４７を操作して脱穀部３、刈取部２を駆動すると、機械条件等が計器パネル３６の各表示具３７，３８，３９に表示される。
その後、収穫作業の準備を終えると、駐車ブレ−キペダル７０の踏み込みを解除し、つづいて変速レバ−６を前側に回動して機体を前進させると共に操作レバ−８を前後方向に傾倒して刈取部２の位置を決め、または左右に傾倒して機体の進行方向を変更しながら分草体１５を所定の条間に合わせる。すると、引き起こしケ−ス１７に沿って斜め後方上方に移動する引き起こしラグ１６で引き起こされた穀稈の株元部は、刈取装置１８によって切断されて刈取穀稈搬送装置１９に受け継がれ後方上方に搬送される。
【００２２】
そして、搬送終端部に到達した穀稈は穀稈自動送り込み装置２０に挟持されて後方に搬送され、カッタ−等の排稈処理装置に送り込まれて処理されるが、穀稈の穂部は扱室内に送り込まれて脱穀処理される。これにより生じた穀粒などの処理物は風選されて穀粒とわら屑に分離され、穀粒は搬送装置によってタンク４に送り込まれ収容される。その後、タンク内の穀粒が満杯になると、運転者は収穫作業を中断して穀粒の排出操作をすれば、穀粒は縦揚穀装置２１及び排出オ−ガ２２を取ってこの排出口から機外に排出されるので、トラック等の運搬車に移し換えればよい。
【００２３】
このような、収穫作業において、例えば穀稈の倒伏が大きい場合など、未刈り穀稈側の最も左に位置する分草体１５を条間に合わせる必要があるが、そのとき運転部の左側前部における前側操作壁９は前後方向の幅が小さいので、運転者は前側に近づくことができ前記条合わせも容易になる。また、駐車ブレ−キペダル７０の踏み込みも容易である。
【００２４】
また、右手で操作している握り部５９の上面のボタンスイッチＳ１，Ｓ２，Ｓ３，Ｓ４の指操作により、操向クラッチを入り切りして機体の進行方向を直進と左・右緩旋回及び刈取部２を諸定位置まで昇降する。従って、収穫作業において、穀稈の踏み倒しを防止し、操作性の向上を図れる。
（別実施例１）
握り部５９の上面のボタンスイッチＳ５，Ｓ６，Ｓ７，Ｓ８の指操作により、押している間スイッチを入りにしており、その間、操向クラッチを入り切りして機体の進行方向を直進と左・右緩旋回及び刈取部２を昇降し停止位置の選択できる構成である。この手段により、作業者はスイッチの操作をしていることを認識しているので、作業の誤操作を防止できる。
【００２５】
（別実施例２）
握り部５９の上面には、横方向及び縦方向に間隔を置いて、指操作できるボタンスイッチＳａ，Ｓｂ，Ｓｃ，Ｓｄを設けている。該横方向に配置したボタンスイッチの中で、Ｓａを指で押すことにより前記操向クラッチを切りにして機体の進行方向を緩やかに左旋回（左緩旋回）し、Ｓｂを指で押すことにより前記操向クラッチを切りにして機体の進行方向を緩やかに右旋回（右緩旋回）する。
【００２６】
縦方向に配置したボタンスイッチの中で、Ｓｃを指で押すことによりアクチュエ−タにより変速手段を作動して刈取部２の速度を高速にし、Ｓｄを指で押すことによりアクチュエ−タにより変速手段を作動して刈取部２の速度を低速にする。
従って、操作レバ−８を右手で操作しながら、右手の指で刈取部２の速度を変速でき穀稈の倒伏度に合った速度に調節でき操作性の向上を図れる。
【００２７】
（別実施例３）
握り部５９の上面には、横方向及び縦方向に間隔を置いて、指操作できるボタンスイッチＳｅ，Ｓｆ，Ｓｇ，Ｓｈを設けている。該横方向に配置したボタンスイッチの中で、Ｓｅを指で押すことにより前記操向クラッチを切りにして機体の進行方向を緩やかに左旋回（左緩旋回）し、Ｓｆを指で押すことにより前記操向クラッチを切りにして機体の進行方向を緩やかに右旋回（右緩旋回）する。
【００２８】
縦方向に配置したボタンスイッチの中で、Ｓｇを指で押すことによりアクチュエ−タにより変速手段を作動して引き起こし装置１７の速度を高速にし、Ｓｈを指で押すことによりアクチュエ−タにより変速手段を作動して引き起こし装置１７の速度を低速にする。従って、操作レバ−８を右手で操作しながら、右手の指で引き起こし装置１７の速度を変速でき穀稈の倒伏状態や圃場条件に合った速度に調節でき作業及び操作性の向上を図れる。
