【0025】
図3に明示するように、前記運転部には、座席支持台8の上部に連結した前記運転座席3、前記座席支持台8の前側に位置する運転ステップ9、運転ステップ9の前端側に連設した操縦塔10、運転ステップ9の機体内側の横側に位置するサイドカバー11、このサイドカバー11の上部に連設してあるサイド運転パネル12、運転ステップ9の機体横外側に運転ステップ9の上面より一段下がって位置する乗降用ステップ13、座席支持台8の横側壁部の前角部に連設した乗降用把手14を備えてある。
【0026】
前記操縦塔10は、運転座席3の前方に位置するフロント運転パネルを操縦塔10の上板部10aで形成するように、かつ、機体の操向操作を行う運転レバー16を操縦塔10の上板部10aで支持するように、さらには、運転者が身体の安定化を図るべく支持するための固定ハンドル18を操縦塔10の両横板部10bで支持するように作成してある。
【0027】
前記サイドカバー11は、運転ステップ9上のスペースの機体内側における座席支持台8と操縦塔10との間を閉じて原動部で発生する熱気や騒音、刈取り前処理部6で発生する塵埃などが運転部に入り込むことを防止する遮蔽部材になるように形成してある。
【0028】
図3及び図4に明示するように、前記座席支持台8は、原動部のエンジン2やその付属機器の上方を覆うとともに運転座席3が載るように形成した天板部8aと、エンジン2やその付属機器の後側を覆うとともに上端側が運転座席3の後側をカバーするように形成した後縦壁部8bと、エンジン2やその付属機器の機体横外側を覆うとともに上端側が運転座席3の横側をカバーするように、かつ、前記乗降用把手14を支持するように形成した横側壁部8cと、エンジン2やその付属機器の前方側を覆うように、かつ、エンジン燃焼用空気の取入れ口8eを備えるように形成した前縦壁部8dとから成るエンジン用のボンネットに形成してある。
【0029】
座席支持台8の前記天板部8a、後縦壁部8b、横側壁部8c及び前縦壁部8dのそれぞれを合成樹脂で成型することによって、座席支持台8を軽量化するように合成樹脂製にしてある。運転ステップ9の床板9a及び床板9aの両端側に連結する横側板9dを有するステップ本体を合成樹脂で成型することにより、運転ステップ9を軽量化するように合成樹脂製にしてある。操縦塔10の前板部10c、上板部10a及び両横板部10b,10bのそれぞれを合成樹脂で成型することによって、操縦塔10を軽量化するように合成樹脂製にしてある。
【0030】
座席支持台8、運転ステップ9及び操縦塔10を、別々に合成樹脂で成型した後にねじとか接着材とかの連結手段によって連結するか、あるいは、同時に合成樹脂で成型することによって、座席支持台8の前端側と運転ステップ9の後端側とを、運転ステップ9の前端側と操縦塔10の下部とをそれぞれ連結してある。前記サイドカバー11を座席支持台8、運転ステップ9及び操縦塔10とは別の部品に作製し、サイドカバー11の前端側を操縦塔10の機体内側の横側壁部10bに、サイドカバー11の後端側を座席支持台8の天板部8a及び前縦壁部8dの機体内側端部にそれぞれ連結してサイドカバー11が操縦塔10と座席支持台8の機体内側どうしにわたって連結するように構成してある。すなわち、座席支持台8と運転ステップ9と操縦塔10とを、座席支持台8と操縦塔10の機体内側の横端側どうしがサイドカバー11によって連結された一つの構造体に構成してある。
【0031】
サイドカバー11としては、座席支持台8、運転ステップ9及び操縦塔10の三部材とは別部材に作製して座席支持台8と操縦塔10とにわたって連結する他、つぎの構成を採用して実施してもよい。すなわち、サイドカバー11を座席支持台8、運転ステップ9及び操縦塔10の三部材を合成樹脂で同時に成型する際に同時に成型して、座席支持台8、運転ステップ9及び操縦塔10との一体部品に作製することにより、サイドカバー11が合成樹脂製になるとともに座席支持台8と操縦塔10とにわたって連結するように構成して実施してもよい。また、サイドカバー11を座席支持台8、運転ステップ9及び操縦塔10のうちの一つ又は2つの部材と同時に合成樹脂で成型するとともに、この成型によっては連結しない座席支持台8と操縦塔10の一つまたは両方に対しては成型後にねじや接着などの連結手段で連結することにより、サイドカバー11が合成樹脂製になるとともに座席支持台8と操縦塔10とにわたって連結するように構成して実施してもよい。
【0032】
操縦塔10の下部を走行機体の機体フレーム19に連結する支持ブラケット19aに走行機体横向きの軸芯Pまわりで回動自在に連結することにより、座席支持台8、運転ステップ9及び操縦塔10を、走行機体に前記軸芯Pまわりで一体に回動操作できるように支持させ、座席支持台8と運転ステップ9と操縦塔10とを図5に実線で示す開き位置と、図1に示す閉じ位置とに一挙に切り換えできるようにしてある。すなわち、座席支持台8、運転ステップ9及び操縦塔10を形成している一つの構造体を前記軸芯Pまわりで走行機体に対して回動操作し、図5に実線で示すように、座席支持台8が走行機体フレーム19から上方に離間する状態にすると、前記構造体が前記開き位置になって座席支持台8が原動部のエンジン2を、運転ステップ9が原動部の前側をそれぞれ開放する。このとき、サイドカバー11が刈取り前処理部6の横側を開放する。図1に示すように、座席支持台8が走行機体フレーム19に載る状態にすると、前記構造体が前記閉じ位置になり、座席支持台8がエンジン2とその付属機器を、運転ステップ9が原動部の前側をそれぞれ覆うようになる。このとき、サイドカバー11が刈取り前処理部6の横側を覆うようになる。
すなわち、作業を行うなど通常時は、座席支持台8、運転ステップ9及び操縦塔10を前記閉じ位置にして、原動部のエンジン2やその付近を座席支持台8、運転ステップ9及びサイドカバー11でカバーしておくとともに運転座席3などの使用を可能にする。そして、原動部のエンジン2などを点検したり修理するとか、エンジン2の回転出力がクローラ走行装置1を駆動する走行ミッションに伝達される伝動機構を点検したり修理するとかの際には、座席支持台8、運転ステップ9及び操縦塔10を前記開き位置に切り換え、座席支持台8でカバーされる部分の他に運転ステップ9でもサイドカバー11でもカバーされる部分も開放し、広い作業用スペースを確保して作業する。
【0034】
は、さらに別の実施形態を備える運転部構造を示し、座席支持台8、運転ステップ9、操縦塔10及びサイドカバー11が走行機体に対して一体に回動する走行機体横向きの軸芯Pを操縦塔10の上端部に配置してある。すなわち、座席支持台8が閉じ位置から上昇していくに伴って操縦塔10の上端側が軸芯Pより機体前方側に突出していくことになっても、その突出長さが極力小になるように配置してある。これにより、刈取り前処理部6の機体横方向に並ぶ複数の引き起こし装置6a,6bのうちの最も運転部側に位置する引き起こし装置6bの一部が操縦塔10の直前方に位置しているとともに、座席支持台8を閉じた際の操縦塔10と前記引き起こし装置6bとの間隔が狭くなっても、その間隔の割りには、操縦塔10が引き起こし装置6bに当たらないで座席支持台8が機体フレーム19から大きく上昇開放して原動部を大幅に開放する。
【0035】
は、さらに別の実施形態を備えるコンバインを示し、走行機体の後部にエンジン2を有する原動部を設け、この原動部から穀粒タンク5と脱穀装置4の間を通って走行機体の前端側に至るベルト式伝動機構20により、エンジン2の回転出力を走行ミッション21に伝達するように構成してある。
そして、通常時は、座席支持台8、運転ステップ9、操縦塔10及びサイドカバー11を実線で示す前記閉じ位置にして、前記ベルト伝動機構20のうちの穀粒タンク5より前側に位置する伝動機構部分20aや走行ミッション21の入力部を座席支持台8、運転ステップ9及びサイドカバー11でカバーしておくとともに運転座席3などの使用を可能にする。そして、前記伝動機構部分20aや走行ミッション21を点検したり修理するとかの際には、座席支持台8、運転ステップ9、操縦塔10及びサイドカバー11を二点鎖線で示す前記開き位置に切り換え、伝動機構部分20aや走行ミッション21を開放して作業する。
