Description

【0001】
【発明の属する技術分野】
本発明は、ブロー成形された樹脂製の操縦塔が機体の運転部フレームの前端部に立設されている収穫機の運転部構造に関する。
【0002】
【従来の技術】
上記収穫機において、従来、たとえば特開2002−37139号公報に示されるように、操縦塔の下端側に、中空構造の載置取り付け部と、この載置取り付け部の複数箇所から延出した舌片とを設け、載置取り付け部を運転部フレームの上向き支持面に載置して支持させ、舌片を運転部フレームの前向き面に取り付けボルトによって締め付け連結することにより、操縦塔の下端側を運転部フレームに支持させる取り付け構造を採用していた。
【0003】
【発明が解決しようとする課題】
上記した従来の取り付け構造を採用した場合、載置取り付け部から延出する複数の舌片のために成形金型の構造が複雑になり、成形金型の面から製作費が高くなっていた。また、舌片の数を多くすることによって操縦塔の取り付けを所望強度にせねばならず、この面からも成形金型の構造が複雑になって製作費が高くなっていた。また、締め付け連結に多くの手間が掛かる問題が発生していた。
【0004】
本発明の目的は、操縦塔を強固に支持させることができながら安価にかつ組み立て容易に得られる収穫機の運転部構造を提供することにある。
【0005】
【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。
【0006】

ブロー成形された樹脂製の操縦塔が機体の運転部フレームの前端部に立設されている収穫機の運転部構造において、前記操縦塔の前記運転部フレームに支持されている取り付け部に、前記運転部フレームの機体上方向きの上向き支持面に載置して受け止め支持されている中空構造の載置取り付け部と、前記運転部フレームの機体前方向きの前向き支持面に当接して締め付け連結されている中空構造の締付け取り付け部とを、互いに内部が連通し合った状態に形成して備えてある。
【0007】
〔作用〕
操縦塔の前記取り付け部に、互いに内部が連通し合った中空構造の載置取り付け部と、中空構造の締付け取り付け部とを備えてあるものだから、構造簡単な成形金型を使用して操縦塔を作製しながら、さらに、締め付け取り付け部に中空構造のために優れた強度を備えさせて、その分、締め付け箇所の数を少なく済ませるとともに必要な締め付け手間を少なく済ませながら操縦塔を運転部フレームに強固に締め付け連結できる。
【0008】
〔効果〕
従って、締め付け取り付け部に優れた強度を備えさせて操縦塔を所望強度で強固に取り付けることができる。その割には、構造簡単な成形金型によって安価に作製してコストダウンでき、さらに、少ない締め付け手間で能率よく組み立てできる。
【0009】
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。
【0010】
〔構成〕
請求項1による発明の構成において、前記締付け取り付け部に、取り付けボルトが挿通しているコンプレッション部を備えてある。
【0011】
〔作用〕
取り付けボルトがコンプレッション部を挿通して締付け取り付け部を運転部フレームに締め付け連結するものだから、締め付け力を強くしても締付け取り付け部が変形しにくく、締め付け連結を強固に行なえる。
【0012】
〔効果〕
従って、締付け取り付け部の運転部フレームに対する締め付けを一層強固に行い、操縦塔の取り付けが一層強固に行なえる。
【0013】
請求項3による発明の構成、作用、効果はつぎのとおりである。
【0014】
〔構成〕
請求項1又は2による発明の構成において、前記載置取り付け部の前記上向き支持面に当接している下壁と、この下壁に連続している機体上下向きの縦壁とにわたって形成し、かつ、前記下壁と前記縦壁とによって形成される角部を除去した状態に形成した配線孔を備えてある。
【0015】
〔作用〕
載置取り付け部に配線孔を備えさせるのに、下壁と縦壁とにわたって形成し、かつ、下壁と縦壁とによって形成される角部を除去した状態に形成して備えてあるものだから、下壁又は縦壁のみを貫通する状態に形成して備えるに比し、下壁及び縦壁にできる貫通孔の大きさが小さくなって下壁及び縦壁の貫通孔に起因する強度低下を抑制しながら必要な大きさの配線孔を備えさせられる。
【0016】
〔効果〕
従って、配線孔を大きくして太いとか数多い配線でも容易に挿通させて能率よく配線作業できる。その割には、下壁及び縦壁の強度低下を抑制して操縦塔を強固な状態に維持できる。

【0022】
図4、図5、図9などに示すように、操縦塔20の前記取り付け部24に、操縦塔20の裏壁22に上端側が連続している機体上下向きの縦壁26aを備えた載置取り付け部26と、操縦塔20の表壁25の下端側に上端側が連続している前壁27aを備えた締付け取り付け部27とを備えてある
【0023】
載置取り付け部26は、前記縦壁26a、及び、この縦壁26aの下端に後端が連続している下壁26bを備えて構成してあり、かつ、操縦塔20をブロー成形する際に同時にブロー成形することによって作製してあって、中空構造になっている。
【0024】
締め付け取り付け部27は、前記前壁27a、及び、この前壁27aの下端部に下端側が、上端側が前記下壁26bの前端部にそれぞれ連続している後壁27bを備えて構成してあり、かつ、操縦塔20及び載置取り付け部26をブロー成形する際に同時にブロー成形することによって作製してあって、前記載置取り付け部26と内部どうしが連通した中空構造になっている。この締付け取り付け部27の機体横方向に並ぶ2箇所に、締付け取り付け部27をブロー成形する際に前壁27aと後壁27bの一部どうしが連結し合うように成形した図8の如きコンプレッション部27cを設けてある。
【0025】
図4、図6(ロ)に示すように、前記載置取り付け部26の下壁26bを運転部フレーム30の前記上向き支持面33に載置して、この上向き支持面33によって載置取り付け部26を受け止め支持させてある。これとともに、図8に示すように、前記締め付け取り付け部27の前記2箇所のコンプレション部27cを各別に挿通させて連結フレーム32に装着した2本の取り付けボルト28によって、締付け取り付け部27を運転部フレーム30の前記前向き支持面34に対して後壁27aで当接させるとともに締付け連結してある。
【0026】
図5に示すように、操縦塔20の前記取り付け溝23を、一端側が操縦塔20の横一端側で操縦塔20の上下方向に沿っている縦溝になり、他端側が操縦塔20の上端側で操縦塔20の横方向に沿っている横溝になった屈曲溝に形成してある。図4、図5、図7に示すように、前記操縦塔支持杆35の前記縦向き部分35aが取り付け溝23の縦溝部分に、前記操縦塔支持杆35の横向き部分35bが取り付け溝23の横溝部分にそれぞれ入り込むようにし、操縦塔20の上端部の裏面側に当て付けて複数本の連結ボルト37aによって固定した取り付け板金37と操縦塔20とによる操縦塔支持杆35の挟持によって、操縦塔20を操縦塔支持杆35に固定してある。
【0027】
図9に示すように、操縦塔20の前面側に、前記操向レバー11を変速装置の操作部に連係させる操作ケーブル(図示せず)などの連係部材を収容し、かつ、この連係部材などを覆う化粧カバー50を組み付ける凹入部40、前記操作ケーブルが挿通するケーブル孔41、前記化粧カバー50の周部を受け止め支持する段部42のそれぞれを、操縦塔20のブロー成形の際に同時にブロー成形して設けてある。

【0029】
つまり、刈取り部5の機体横方向に並んでいる複数の引起装置5aのうち、運転部2に隣接している引起装置5aの横側に、図10、図11の如き防音カバー51を装着してある。この防音カバー51は、引き起こし爪の移動に伴って発生するなどの駆動音の伝達を抑制するものである。刈取り部5を持ち上げ操作した際、防音カバー51の下端側が操縦塔20の横側に入り込んでくるが、防塵カバー部43の前記引退形状のために、防音カバー51と防塵カバー部43との緩衝を回避しながら刈取り部5を上昇させられるようにしてある。
【0030】
図10、図11に示すように、前記防音カバー51の下端側が、刈取り部5の分草フレームに支持されている丸棒材で成る支持部52に係止して支持され、防音カバー51の上端側が防音カバー51に付設してある取り付けネジ53によって引き起装置5aのフレームに止着されており、これにより、防音カバー51は引起装置5aに対して着脱自在に付いている。
【0031】
図5などに示すように、操縦塔20の前記載置取り付け部27に配線孔44を設けてある。この配線孔44は、前記化粧カバー50が支持している前照灯54などのための電線を操縦塔20の内部から引き出し、連結フレーム32の配線孔32aを通して配線するためのものであり、図8などに示す如く形成してある。すなわち、配線孔44は、載置取り付け部26の前記下壁26bと前記縦壁26aとにわたって形成し、かつ、その下壁26bと縦壁26aとによって形成されている角部を除去した状態に形成してある。つまり、配線孔44の大きさの割には、下壁26b及び縦壁26aにできる孔が小さくなるようにしながら配線孔44を設けてある。
【0032】
