Description

【０００１】
【発明の属する技術分野】
本発明は、運転座席を支持する座席支持台と、この座席支持台の前方に位置する操縦塔と、座席支持台と操縦塔の間に位置するサイドカバーとによって囲われる居住空間を備えているコンバインの運転部構造に関する。
【０００２】
【従来の技術】
上記コンバインにおける従来の運転部は、運転部床の床面が狭ければ、居住空間の上側での平面積も床面積と同程度の狭い面積になるものであった。また、居住空間が平面視で矩形のものであった。
【０００３】
【発明が解決しようとする課題】
たとえば運転部から穀稈の搬送状況を知るなど刈取り部を見る場合、身体を刈取り部に近づけるほど見やすくなる。ところが、従来、運転部床の床面が狭いものの場合、刈取り部に近づけにくくなっていた。
本発明の目的は、運転部床の広さの割りには身体を刈取り部などに近づけやすくできるコンバインの運転部構造を提供することにある。
【０００４】
【課題を解決するための手段】
請求項１による発明の構成、作用、効果はつぎのとおりである。
【０００５】
〔構成〕
運転座席を支持する座席支持台と、この座席支持台の前方に位置する操縦塔と、座席支持台と操縦塔の間に位置するサイドカバーとによって囲われる居住空間を備えているコンバインの運転部構造において、
前記サイドカバーの内側面を、運転部床の床面上からサイドカバーの上端に至るまで、サイドカバーの上端に至るほどより居住空間外方側に位置する状態に傾斜した傾斜面に形成
して、前記居住空間の前記サイドカバーの上端と等しいレベルにおける平面積が運転部床の床面積より大である状態に構成し、前記サイドカバーの後部側に、中空部を備えた後側サイドカバー部分を一体形成し、操作レバーを案内するガイド溝を備えた操作レバーガイドを、前記中空部を形成している中空部周囲の後側サイドカバー部分の上部と前記座席支持台の天板部とに渡って連結してある。
【０００６】
〔作用〕
刈取り部を見通すなど上半身を居住空間から外側に突き出す際、居住空間のサイドカバー上端レベルにおける平面積が床面積と同一である従来によるものと、居住空間のサイドカバー上端レベルにおける平面積が床面積より大である本発明によるものとでは、床面積が同一であっても、本発明によるものの方が、居住空間上側と床面との面積差による分だけより外側に遠くまで突き出しやすくなる。
【０００７】
〔効果〕
運転部床面が比較的狭くて走行機体の機体フレーム上の狭いスペースにも設置しやすいものにしながら、床面積の割りには、身体を刈取り部により接近させて刈取り部を広範囲にわたって容易に見通すことができるなど、有利に作業できるものになった。
【０００８】
請求項２による発明の構成、作用、効果はつぎのとおりである。
【０００９】
〔構成〕
請求項１による発明の構成において、前記座席支持台と前記操縦塔との間に位置する運転部床を備え、前記座席支持台と前記サイドカバーと前記操縦塔と前記運転部床とを、一つの構造体を形成する状態でこの構造体の前端側に位置する機体横向きの軸芯まわりで揺動自在に走行機体フレームに支持されるとともに、座席支持台が走行機体フレームに連結する使用状態と、座席支持台が走行機体フレームから上昇離間する開き状態とに一挙に揺動切り換えできるように構成してある。
【００１０】
〔作用〕
通常時は座席支持台によって覆われる走行機体側部分を開放する際、座席支持台、運転部床、操縦塔、サイドカバーのそれぞれを一体にこの一つの構造体の前端側に位置する軸芯まわりで機体フレームに対して揺動させ、前記走行機体側部分が大きく開放するとともにその付近も開放し、さらには、その開放部分を修理や点検する際の障害物が開放部分の横外側に存在しない状態に開放することを可能にするものである。
また、座席支持台を開き状態にすると、サイドカバーも上昇揺動することにより、通常時にはサイドカバーに対して運転部側とは反対側に位置している伝動装置や刈取り部の装置部分も運転部側から点検や修理できるように開放できる。
【００１１】
〔効果〕
座席支持台をエンジンボンネットに兼用してカバーする原動部を点検や修理するとか、座席支持台やサイドカバーに対して運転部側と反対側に位置する伝動装置とか刈取り部の装置部分を点検や修理するとかの際、その原動部や装置部分を大きく、かつ、点検や修理の障害物がないように開放にして楽に能率よく点検や修理作業できるように、メンテナンス面でも有利なものに得られる。
【００１２】
【発明の実施の形態】
図１及び図２に示すように、クローラ式走行装置１によって自走し、かつ、運転座席１１が備えられている運転部１０、運転座席１１の下方に位置するエンジン２が備えられている原動部をそれぞれ有する走行機体の運転部１０の横側に、引き起こし装置２１、防塵カバー２２が備えられている刈取り部２０を昇降操作自在に取り付け、この刈取り部２０の後側に位置する脱穀装置３、及び、運転部１０の後側に位置する樹脂製の穀粒タンク４を前記走行機体に設け、脱穀装置３の後側に排ワラ処理装置５を設け、穀粒タンク４の底側が連結する底スクリューケース６の後部に穀粒搬出装置７を連結して、コンバインを構成してある。
【００１３】
すなわち、刈取り部２０は、稲などの植立穀稈を前記引き起こし装置２１によって引き起こし処理するとともにバリカン型刈取り装置２３によって刈取り処理し、刈取り穀稈を前記防塵カバー２２の下方に位置する縦搬送装置（図示せず）によって搬送して脱穀装置３の脱穀フィードチェーン３ａの始端部に供給する。このとき、塵埃が飛散することを前記防塵カバー２２によって防止する。
【００１４】
脱穀装置３は、脱穀フィードチェーン３ａによって刈取り穀稈の株元側を挟持搬送させながら穂先側を脱穀部に供給して脱穀処理し、脱穀粒を前記穀粒タンク４に供給し、脱穀排ワラを前記排ワラ処理装置５に供給する。この排ワラ処理装置５は、細断処理状態に切り換え操作されることによって脱穀排ワラを細断して圃場に放出していき、長ワラ処理状態に切り換え操作されることによって脱穀排ワラを長ワラ状態のままで圃場に放出していく。穀粒搬出装置７は、前記底スクリューケース６の内部に位置する底スクリュー６ａに接続する縦スクリューコンベア７ａと、この縦スクリューコンベア７ａの上端側に接続する横スクリューコベア７ｂとで成り、底スクリュー６ａからの脱穀粒を縦スクリューコンベア７ａによって揚送して横スクリューコンベア７ｂに供給し、この横スクリューコンベア７ｂの吐出口７ｃから排出する。
【００１５】
図３及び図５に明示するように、前記運転部１０には、座席支持台１２、この座席支持台１２の天板部１２ａの上面側に連結している前記運転座席１１、座席支持台１２の前方に位置する操縦塔１３、座席支持台１２と操縦塔１３の間に位置する運転部床１４、座席支持台１２と操縦塔１３の左横端どうしの間に位置して刈取り部２０や原動部で発生する塵埃や駆動音とか熱気が運転部１０の居住空間に入りにくいようにこの居住空間の下側の刈取り部側を覆うサイドカバー１５、このサイドカバー１５の上端側と前記座席支持台１２の天板部１２ａとにわたって連結している操作レバーガイド１６、この操作レバーガイド１６の前端と操縦塔１３の左横端との間に位置する運転パネル１７、座席支持台１２と操縦塔１３とサイドカバー１５とによって囲われた下部側の居住空間Ｓと、運転座席１１を備える上部側の居住空間とで成る操縦用の居住空間、座席支持台１２と操縦塔１３の右横端どうしの間に位置する乗降口のそれぞれを備えてある。
【００１６】
操縦塔１３には、刈取り部２０の昇降操作と走行機体の操向操作とを行う操作レバー３０、操縦者が身体の安定化を図るべく支持する握り棒３１を取り付けてある。操作レバーガイド１６には、走行用主変速装置を操作する主変速レバー３２、走行用副変速装置を操作する副変速レバー３３、脱穀クラッチを切り換え操作する脱穀レバー３４それぞれの操作を案内するガイド溝を備えてある。運転パネル１７には、排ワラ処理装置５の排ワラカッターにワラ詰まりが発生すると点灯して警報する詰まり警報ランプ、穀粒タンク４が満杯になると点灯して報知する満杯ランプ、エンジン冷却水が異常に温度上昇すると点灯して警報する水温ランプ、エンジンオイルが減少すると点灯して警報するオイルランプ、バッテリーの充電不良が発生すると点灯して警報する充電ランプ、エンジン２の負荷状態を示すエンジン回転計と負荷表示部を備えてある。
【００１７】
前記運転部床１４の床面１４ａのうちの操縦塔１３の下方に位置する前端面部分１４ｂを、機体前方側ほど高レベルに位置する前上がり傾斜面に形成してある。
【００１８】
前記座席支持台１２は、前記原動部にエンジン２の燃焼用空気を吸引させる上向き吸気口３５ａ及び前向き吸気口３５ｂを備える吸気塔３５が後端側に連結するように、かつ、前記運転座席１１を上面側に取り付けるように構成した前記天板部１２ａと、この天板部１２ａの前端部に上端部が連結し、下端側が前記運転部床１４に連結するように構成した前側壁部１２ｂと、前記吸気塔３５が後端側に連結するように、かつ、運転座席１１の右横側を覆うように、さらに、前記天板部１２ａと前側壁部１２ｂとによって囲われる空間の右横側を覆うように構成した横外側壁部１２ｃとによって構成してある。横外側壁部１２ｃには、運転部に乗降する際などに使用する握り部Ｇを形成する貫通孔Ｈを備えてある。
【００１９】
図６に示すように、前記天板部１２ａは、原動部の上方を覆うとともに中空部Ｋ１を備えるように形成してある。前記前側壁部１２ｂは、原動部の機体前方側を覆うとともに原動部にエンジン２の燃焼用空気を吸引させる吸気口Ａ１を備えように形成してある。前記横外側壁部１２ｃは、原動部の機体横外側を覆うように形成してある。
【００２０】
すなわち、座席支持台１２が、エンジンボンネットになり、原動部で発生するエンジン２の駆動音や放熱が天板部１２ａの中空構造による遮音や遮熱作用で居住空間に伝わりにくくしながら、かつ、エンジン燃焼用空気が前側壁部１２ｂから吸引されることを可能にしながらエンジン２の上方、機体前方側、機体横外側を覆うようにしてある。
【００２１】
座席支持台１２の下端側と運転部床１４の後端側とを連結し、操縦塔１３の下端部に備えてある左右一対の連結部３１ａによって操縦塔１３と運転部床１４の前端部とを連結し、サイドカバー１５は、座席支持台１２の天板部１２ａと操縦塔１３の横側とにわたって連結しているとともに運転部床１４にも連結している。前記連結部３１ａを、走行機体の機体フレーム８の前端部から延出するとともに前記一対の連結部３１ａ，３１ａの間に入り込むように構成した取付け部８ａに機体横方向の軸芯Ｐまわりで回動自在に連結してある。これにより、座席支持台１２と運転部床１４と操縦塔１３とサイドカバー１５とが、一つの構造体を形成しているとともにこの構造体の前端側に位置する機体横向きの前記軸芯Ｐまわりで揺動するように機体フレーム８に支持されていて、座席支持台１２と運転部床１４と操縦塔１３とサイドカバー１５とを一挙に機体フレーム８に対して揺動操作できるとともに、この揺動操作を行うことにより、図１及び図３に示す如く座席支持台１２が機体フレーム８に連結して原動部を覆う使用状態と、図４に示す如く座席支持台１２が機体フレーム８から上昇離間して原動部を開放する開き状態とに切り換えられる。
【００２２】
すなわち、通常時は、座席支持台１２を前記使用状態にして運転座席１１の使用を可能にするとともにエンジンボンネットとして使用する。そして、原動部や、刈取り部２０の前記縦搬送装置などサイドカバー１５で覆われる装置部分を点検したり修理する際、座席支持台１２を前記開き状態に切り換え、原動部を開放するとともに刈取り部２０の前記装置部分の横側を開放する。このとき、主変速レバー３２、副変速レバー３３、脱穀レバー３４は、上昇揺動する操作レバーガイド１６のガイド溝から抜け外れる。
【００２３】
前記座席支持台１２の天板部１２ａ、前側壁部１２ｂ、横外側壁部１２ｃ、運転部床１４、操縦塔１３、サイドカバー１５、操作レバーガイド１６、吸気塔３５のそれぞれは、合成樹脂で作成してある。
【００２４】
図７及び図９に示すように、前記サイドカバー１５の内側面のうちの段差形成面部分１５ａより前側に位置する前内側面部分１５ｂと、段差形成面部分１５ａより後側に位置する後内側面部分１５ｃとを、機体上下方向視で凸側が前記下部側居住空間Ｓの外側に位置する凹入形状の湾曲面となり、かつ、サイドカバー１５の上端１５ｕに至るほど前記下部側居住空間Ｓの外側に位置する傾斜面となるように形成し、図５及び図８に示す如く前記下部側居住空間Ｓのサイドカバー１５の上端１５ｕと等しいレベルにおける平面積ＳＵが運転部床１４の床面１４ａの面積ＦＳより大になるように構成し、かつ、前記下部側居住空間Ｓの刈取り部３０側に位置する居住空間部分ＳＡがサイドカバー１５の上端１５ｕと等しいレベルにおいて機体上下方向視で凸側が居住空間外側に位置する状態で湾曲している凹入湾曲形状の居住空間部分になるように構成してある。前記操作レバーガイド１６の下部側居住空間Ｓに対向する側縁のうちのサイドカバー１５の前記段差形成面部分１５ａに対応する段差形成側縁分１６ａより前側に位置する前側縁部分１６ｂを、サイドカバー１５の前記前内側面部分１５ｂの上端に沿って湾曲する湾曲形状に形成し、前記操作レバーガイド１６の下部側居住空間Ｓに対向する側縁のうちの前記段差形成側縁分１６ａより後側に位置する後側縁部分１６ｃを、サイドカバー１５の前記後内側面部分１５ｃの上端に沿って湾曲する湾曲形状に形成し、刈取り部２０を見るなどの際、身体を操作レバーガイド１６が障害物にならないようにして前記下部側居住空間部分ＳＡに位置させて刈取り部３０に極力寄せることを可能にしてある。
【００２５】
図７に示すように、前記サイドカバー１５を形成する際、このサイドカバー１５のうちの前記段差形成面部分１５ａを有するとともに機体後方側に位置する後側サイドカバー部分１５ｄが中空部Ｋ２を備える二重板状になり、この後側サイドカバー部分１５ｄと操縦塔１３との間に位置する前側サイドカバー部分１５ｅが中実の板状になり、前側サイドカバー部分１５ｅの居住空間内外方向での厚さが後側サイドカバー部分１５ｄの居住空間内外方向での厚さよりも小になり、後側サイドカバー部分１５ｄの外側面が前側サイドカバー部分１５ｅの外側面よりも下側居住空間Ｓの外方側に突出するように形成してある。これにより、原動部で発生するエンジン２の駆動音や放熱が後側サイドカバー部分１５ｄの中空構造による遮音や遮作用で居住空間Ｓに伝わりにくい状態にサイドカバー１５が遮蔽作用する。その割りには、前側サイドカバー部分１５ｅと後側サイドカバー部分１５ｄとの厚さの差と、外側面の段差とにより、サイドカバー１５が極力コンパクトになり、下側居住空間Ｓが極力広くなる。
【００２６】
図９に示すように、操作レバーガイド１６の上面のうちの主変速レバー３２、副変速レバー３３、脱穀レバー３４それぞれのためのガイド溝を備える上面部分１６ｄを、運転座席１１の方から見やすいように居住空間側ほど低レベルに位置する傾斜面に形成してある。
【００２７】
〔別実施形態〕
前記座席支持台１２の天板部１２ａ、前側壁部１２ｂ、横外側壁部１２ｃ、運転部床１４、操縦塔１３、サイドカバー１５、操作レバーガイド１６、吸気塔３５のそれぞれを合成樹脂で作成して実施するに当たり、それらを個別に作成して連結する他、それらの一部の複数個をブロー成型法によって一挙に作成するとともにこの一体部品とは別にその他を作成した後にそれらを連結するとか、それらの全てをブロー成型法によって一挙に作成するとかの各種の作成方法を採用して実施してもよい。
