Description

【０００１】
【発明の属する技術分野】
本発明は、圃場にて成育した大根や人参等の根菜を収穫する根菜収穫機であって、掘り取った根菜を収納したコンテナを地面上に降ろす装置に関するものである。
【０００２】
【従来の技術】
従来、走行機台上の右側に操縦部を左側に根菜の茎葉部を挟持して後方斜め上方に引き上げる引抜搬送帯を配設し、引抜搬送帯の終端部下方に始端部を位置させて搬送物を受継ぎ操縦部後方の右側に送る横搬送帯を横設し、操縦部と横搬送帯の間にコンテナを載置するフォ−ク状の受け部材と作業者用のステップを前後にして配置し、前記受け部材を横移動手段により機体の右側方に横移動可能にするとともに、受け部材を横移動手段に対して上下動自在にしてコンテナを地面に降ろす形態にした根菜収穫機は開発されている。また、白菜収穫機の回収部にコンテナの載置スペースと該コンテナに白菜を運ぶ作業場を設け、コンテナを旋回張り出しと昇降自在に移動させるレイアウトにするとともに、前記コンテナをキャッチするフォーク爪を機体外側から内方向に向けた配置にし、これを昇降させる油圧シリンダーを支持する支持フレームを前記回収部の後方側端に立設させ、昇降シリンダーを若干伸長させてコンテナを少し持上げてから９０度回動し、地面にコンテナを接地させるものが特開平０９−１６３８４３号公報に記載されている。
【０００３】
【発明が解決しようとする課題】
しかし、この開発によるものは、コンテナを載置する受け部材を横移動手段により機体の右側方に横移動するときに、コンテナの脚部が走行機台に引っ掛かったり、また側方に横移動したものを下降して地面上に接地させるとき、走行機台の右側部に当たって変形し損傷するなど降ろす場合に問題点があるから、本発明はこの場合にコンテナが走行機台に干渉することなく円滑に降ろすことができるものにし、また作業時に細心の注意を払わなくても作業を安全に行えるものを提供するものである。
【０００４】
【課題を解決するための手段】
この発明の根菜収穫機は、走行機台（１）上の右側に操縦部（Ａ）を左側に根菜の茎葉部を挟持して後方斜め上方に引き上げる引抜搬送帯（２）を配設し、該引抜搬送帯（２）の終端部下方に始端部を位置させて搬送物を受継ぎ、操縦部（Ａ）後方の右側に送る横搬送帯（３）を横設し、前記操縦部（Ａ）と横搬送帯（３）の間にコンテナ（４）を載置する走行機台（１）の前側から後方に向けて延出したフォ−ク状の受け部材（５）と作業者用のステップ（６）を前後にして配置し、前記受け部材（５）を操縦部（Ａ）の背後から機体の左側にかけて走行機台（１）上に立設した横移動手段（Ｂ）により機体の右側方に横移動可能にするとともに、該受け部材（５）を前記横移動手段（Ｂ）に対して上下動自在にしたものにおいて、前記受け部材（５）を走行機台（１）上の一定高さ位置に浮上させてから右側方に所定距離横移動したのち受け部材（５）を地面（Ｇ）上に接地させる構成にしたことから、コンテナを載置する受け部材を横移動手段により機体の右側方に横移動するときに、コンテナの脚部が走行機台に引っ掛かったり、また側方に横移動したものを下降して地面上に接地させるとき、走行機台の右側部に当たらず円滑にして安全に地面上に降ろすことができるようになる。
【０００５】
また、コンテナ（４）内に所定量の収穫物が入ると、油圧シリンダ（３７）による受け部材（５）の上動によってコンテナ（４）は浮上し、可動枠部材（２１）がわのスイッチ（３８）への接触によりＯＮして一定高さ位置で停止する規制手段（７）と横移動範囲（Ｌ）を規制する制限手段（８）を付加してあることにより、コンテナを降ろすとき自動的に一定高さ位置に浮上させたのち右側方に所定量移動するようになって、作業が確実に行えるのである。またコンテナを走行機台上に積み込むときも自動的に所定位置への積み込みが可能になる。
【０００６】
受け部材（５）の上下動を作動させる油圧シリンダー（３７）と横移動を起動する駆動スプロケット（３４）の起動時には、その上下及び左右移動に連動して警報を発する構成にしてあるので、その場合の受け部材の上下動と横移動時には、その移動に連動して警報を発するものにすると、作業者は安全で不測の事態が発生しない。
【０００７】
横搬送帯（３）をステップ（６）から後方に離間可能に構成するとともに、ステップ（６）の終端部には右側方に延出する作用姿勢と機体がわに収納する非作用姿勢とに切替自在にした補助ステップ（６ａ）を設け、且つ、横搬送帯（３）の終端部に補助受板（３ａ）を連結し、これを作用姿勢と収納姿勢とに変更可能にしたことで、横搬送帯をステップから後方に離間可能に構成すると、作業終了時等における点検整備作業が容易に行えるのである。
【０００８】
また、ステップの終端部には右側方に延出する作用姿勢と機体がわに収納する非作用姿勢とに切替自在にした補助ステップを設けたので、コンテナ内に収穫物を入れる作業中は作用姿勢の補助ステップにより行動範囲が大になって作業がしやすく、コンテナを地面上に降ろすときには補助ステップが収納して邪魔にならないようになる。
【０００９】
更に、横搬送帯の終端部に補助受板を連結し、これを作用姿勢と収納姿勢とに変更可能にしたことによって、収穫物をコンテナ内に入れる作業中において、補助受板上に収穫物の搬送されてきたものを一時貯留することができて作業が容易になるのである。
【００１０】
【発明の実施の形態】
【実施例】
以下、本発明による根菜収穫機について実施例図を参照し具体的に説明すると、この根菜収穫機は図４〜図９に示すように、走行クロ−ラ（９）を具備する走行機台（１）上の右側に操縦部（Ａ）を設け運転席（１０）の下方にエンジン部（Ｅ）を配置している。また左側には土中に侵入して根菜の根部を浮き上がらせる振動刃（１１）と、この振動刃（１１）によって浮き上がるものの茎葉部を挟持して後方斜め上方に引き上げる引抜搬送帯（２）を機体後方に長く延設し側方視で緩傾斜状態に斜設してある。
【００１１】
この引抜搬送帯（２）は２つの搬送ベルトを弾圧対設させて浮き上がる根菜の茎葉部を挟持して後方斜め上方に引き上げるもので、斜設状態が調節可能であって引抜搬送帯（２）始端部の対地高さが変更可能であり、終端部近くには挟持して搬送されてくる茎葉部を荒切りするカッタ−を備えるとともに、カッタ−部から後方に排出樋（１２）が延出し、その排出樋（１２）の後端からは布製または樹脂膜からなる落下案内筒（１３）が垂下している。
【００１２】
また、前記振動刃（１１）は上部リンク（１４）と下部リンク（１５）からなる平行リンクの前端部に取着され、上部リンク（１４）によって振動が付与され下部リンク（１５）によって上下動可能であって、稼働時には土中に侵入する深さを調節したり非稼働時には上方に大きく退避するのである。
【００１３】
そして、前記引抜搬送帯（２）始端部の前側には各一対の横回し形の掻上タイン（１６）と縦回し形の引上タイン（１７）からなる前処理装置（Ｃ）が設けられ、該装置（Ｃ）は引抜搬送帯（２）に一体的に取着されて引抜搬送帯（２）と一緒に対地高さが変更するのである。
【００１４】
（３）は平ベルト（３ｂ）と突起付きチエン（３ｃ）を平行にして構成された横搬送帯で、前記引抜搬送帯（２）の終端部下方に始端部を位置させ該搬送帯（２）による吊持状態での搬送物を姿勢変更ロ−ラ（１８）に根部の下側を当接させ横倒れ姿勢にしたものを受継ぎ操縦部（Ａ）後方の右側に向けて横送りするもので、横倒れ姿勢の根部を平ベルト（３ｂ）上に寝かせ茎葉部を突起付きチエン（３ｃ）によって搬送し、その横送りの中途部には荒切りした茎葉部を仕上切りする鋸刃状のカッタ−を備えている。（１９）はそのカッタ−のカバ−、（２０）は突起付きチエン（３ｃ）の後カバ−である。
【００１５】
また、（４）は収穫物を入れるコンテナ、（６）は滑り止め面を有する作業者用のステップであって、コンテナ（４）は前側から後方に向けて延出し間隔をあけて水平状態に並設するフオ−ク状の受け部材（５）（５）上に載置されていて、受け部材（５）（５）とステップ（６）は前記操縦部（Ａ）と横搬送帯（３）の間において前後に配置されるとともに、その受け部材（５）（５）は横移動手段（Ｂ）により機体の左右方向に横移動可能で、かつ横移動手段（Ｂ）に対して上下動自在になっている。
【００１６】
即ち、図１〜図３と図１０〜図１５に示すように、横移動手段（Ｂ）は固定枠部材（２２）と可動枠部材（２１）とから構成されていて、その固定枠部材（２２）は、前記操縦部（Ａ）の背後から機体の左側にかけて走行機台（１）上に立設し、上部がわと下部がわとに左右方向のガイドレ−ル（２３）（２４）を備え、その上部がわのガイドレ−ル（２３）内には可動枠部材（２１）のスライドレ−ル（２５）を上側から押える数個のガイド輪（２６）・・・・と張設するチエン（２７）を有し、下部がわのガイドレ−ル（２４）内にスライドレ−ル（２８）を受ける数個の支持輪（２９）と（３０）・・を有するとともに、各ガイドレ−ル（２３）（２４）内にはスライドレ−ル（２５）（２８）の側面に接触する誘導ロ−ラ（３１）・・をそれぞれ備えている。また（３２）（３３）は上部がわのガイドレ−ル（２３）の両側部に取り付けられて可動枠部材（２１）の横移動を停止するスイッチである。
【００１７】
そして、可動枠部材（２１）には上部がわと下部がわに左右方向のスライドレ−ル（２５）（２８）を備えて組成し、上下の各スライドレ−ル（２５）（２８）が前記固定枠部材（２２）のガイドレ−ル（２３）（２４）に挿入して数個のガイド輪（２６）と支持輪（２９）と（３０）により支持案内されて横移動可能になっている。また前記固定枠部材（２２）がわに張設するチエン（２７）に噛み合う駆動スプロケット（３４）を有し、油圧モ−タ等による駆動スプロケット（３４）の起動により可動枠部材（２１）を横移動させるのである。
【００１８】
また（３５）はこの可動枠部材（２１）上部がわの左側部に取り付けたストップア−ムであって、このア−ム（３５）が前記スイッチ（３２）または（３３）に接触することにより横移動を停止するようにして横移動範囲（Ｌ）を規制する制限手段（８）を構成し、（３６）（３６）は前記受け部材（５）の上下動をガイドするガイド支柱であり、（３７）は上部がわを可動枠部材（２１）に取り付けた油圧シリンダ、（３８）は前記受け部材（５）の上動を停止するスイッチ、（３９）は走行機台（１）上での受け部材（５）の下動を停止するスイッチであって、受け部材（５）を一定高さ位置に浮上させる規制手段（７）を構成している。また（４０）はスライドレ−ル（２８）の右側端部に取着したアウトリガ−で上下に伸縮可能にしてある。
【００１９】
そして、前記受け部材（５）は断面コ形の縦杆（４１）（４１）を横杆（４２）・・により連結して枠体にしたものの両側の下端部に基端部を溶着して前記のように水平状態に並設したもので、その縦杆（４１）（４１）内に前記可動枠部材（２１）のガイド支柱（３６）（３６）を嵌合させ、縦杆（４１）（４１）をガイド支柱（３６）（３６）に対してスライド自在にするとともに、前記油圧シリンダ（３７）のロッド（３７ａ）を最下端の横杆（４２）に連結し、油圧シリンダ（３７）によって可動枠部材（２１）に対して上下動するようになっている。その場合、最下端の横杆（４２）部分がスイッチ（３８）に接触することにより上動が停止され、別スイッチ（３９）のスイッチア−ム（３９ａ）から離れると前記の下動を停止するのである。
【００２０】
これにより、前処理装置（Ｃ）によって根菜の茎葉部が掻上げられるとともに、根菜は振動刃（１１）により浮き上がり、その浮き上がるものの茎葉部が引抜搬送帯（２）に挟持されて引き上げられ吊持状態で後方に搬送される。そして、後方への搬送の終端近くで茎葉部が荒切りされてその切断されたものが排出樋（１２）を通って落下案内筒（１３）から地面（Ｇ）上に落下し、根部は姿勢変更ロ−ラ（１８）により横倒れ姿勢になって横搬送帯（３）の始端部に落下し横倒れ状態で右側に横送りされ、その横送りの途中でカッタ−により茎葉部が仕上切りされて、ステップ（６）上に立っている作業者によって横搬送帯（３）の終端部または補助受板（３ａ）上から順次コンテナ（４）内に入れられていくのである。
【００２１】
そして、コンテナ（４）内に所定量の収穫物が入ると、油圧シリンダ（３７）による受け部材（５）の上動によってコンテナ（４）は浮上し、可動枠部材（２１）がわのスイッチ（３８）への接触によりＯＮして一定高さ位置で停止する。そこで、駆動スプロケット（３４）を起動させるとチエン（２７）を介して可動枠部材（２１）が右側方に向けて横移動し、所定距離横移動するとストップア−ム（３５）が固定枠部材（２２）右側部のスイッチ（３２）をＯＮさせて停止するようになり、コンテナ（４）は走行機台（１）上の外側方に位置するのである。このとき、収穫物がコンテナ（４）内に満杯の状態であると機体のバランスが崩れて機体は右側に傾くようになるがアウトリガ−（４０）によって横転が防止され、油圧シリンダ（３７）により受け部材（５）を下動して接地させ機体の前進により受け部材（５）上のコンテナ（４）を地面（Ｇ）上に降ろすのである。
【００２２】
この機体の前進によりコンテナ（４）を受け部材（５）から地面（Ｇ）上に降ろすときと、機体を後進させて地面（Ｇ）上のコンテナ（４）を受け部材（５）上に載置させるときは後述のように補助ステップ（６ａ）を作用姿勢から機体がわに収納する非作用姿勢にするとともに、補助受板（３ａ）も作用姿勢から収納姿勢に変更するのである。
【００２３】
収穫作業を再開するときは、地面（Ｇ）上の空のコンテナ（４）に対し機体を後進させてコンテナ（４）を受け部材（５）（５）上に載置し前記の降ろすときと逆の動作により走行機台（１）上の所定位置に積み込むのである。
【００２４】
また前記駆動スプロケット（３４）を起動する油圧モ−タの作動と油圧シリンダ（３７）の作動に連動して警報を発するようにし、受け部材（５）即ちコンテナ（４）の横移動時と上下動のときには作業者に注意を喚起する手段を講じてある。なお、コンテナ（４）を地面（Ｇ）上に降ろしたり地面（Ｇ）上のコンテナ（４）を受け部材（５）（５）に載置するとき機体の前進または後進時に警報を発するようにしておくとよい。
【００２５】
また、前記の横搬送帯（３）は図１６〜図１９に示してあるように、この横搬送帯（３）の左側部を１本の脚体（４３）により支持し、その脚体（４３）を走行機台（１）の段違いになっている後端部に前後方向に摺動自在にして左側方に延設した支持ア−ム（４４）に縦軸芯の周りに回動可能に取付け、その前後方向の摺動をハンドル（４５）付きネジ棒（４６）の回動によって行うようにし、横搬送帯（３）の右側部は走行機台（１）に２本の脚体（４７）（４８）により支持し、その脚体（４７）（４８）のうち後側のものにはロ−ラ（４９）を装着して走行機台（１）の後端に嵌合自在にし、前側の脚体（４８）には走行機台（１）上を転動するコロ（５０）とレバ−（５１）の操作により解除可能にしたフック（５２）が取着されている。
【００２６】
したがって、ハンドル（４５）を操作すれば横搬送帯（３）の左側部即ち始端部が前後に移動して前記引抜搬送帯（２）からの収穫物の受継ぎ状態をよくし、またレバ−（５１）を操作してフック（５２）を解除すれば横搬送帯（３）は左側部の脚体（４３）を支点にして後方に回動し、ステップ（６）から離間可能になっている。
【００２７】
また横搬送帯（３）を構成している平ベルト（３ｂ）の右側部である終端部には補助受板（３ａ）が連結され、その補助受板（３ａ）は搬送されてきた収穫物を受けて貯留する作用姿勢と機体がわに傾倒する収納姿勢とに変更可能になっている。
【００２８】
更に、前記作業者用のステップ（６）は図２０〜図２２のように、右側部の終端部には外側方に水平状態に延出する作用姿勢と、倒立して機体がわに収納する非作用姿勢とに切替自在にした補助ステップ（６ａ）が連結されている。なお（５３）は作業者の安全ガ−ドである。
【００２９】
尚、図４〜図６に示してあるように操縦部（Ａ）の運転席上方を覆うサンバイザ−（５４）の取付は操縦部（Ａ）の背後に立設する横移動手段（Ｂ）の固定枠部材（２２）の上面を取付座（５５）にし、また布製または樹脂膜製の覆い（５６）の骨組みのうち前側のものの取付も前記上面を取付座（５７）にしている。
【００３０】
【発明の効果】
本発明は、以上説明したような形態で実施され、次に記載するような効果を奏する。
【００３１】
即ち、走行機台上の右側に操縦部を左側に根菜の茎葉部を挟持して後方斜め上方に引き上げる引抜搬送帯を配設し、該引抜搬送帯の終端部下方に始端部を位置させて搬送物を受継ぎ、操縦部後方の右側に送る横搬送帯を横設し、前記操縦部と横搬送帯の間にコンテナを載置する走行機台の前側から後方に向けて延出したフォ−ク状の受け部材と作業者用のステップを前後にして配置し、前記受け部材を操縦部の背後から機体の左側にかけて走行機台上に立設した横移動手段により、機体の右側方に横移動可能にするとともに、該受け部材を前記横移動手段に対して上下動自在にしたものにおいて、前記受け部材を走行機台上に一定高さ位置に浮上させてから右側方に所定距離横移動したのち受け部材を地面上に接地させる構成にしたことにより、コンテナを載置する受け部材を横移動手段により機体の右側方に横移動するときに、コンテナの脚部が走行機台に引っ掛かったり、また側方に横移動したものを下降して地面上に接地させるとき、走行機台の右側部に当たらず変形破損を防止し、円滑にして安全に地面上に降ろすことができるのである。
【００３２】
また、コンテナ内に所定量の収穫物が入ると、油圧シリンダによる受け部材の上動によってコンテナは浮上し、可動枠部材がわのスイッチへの接触によりＯＮして一定高さ位置で停止する規制手段と横移動範囲を規制する制限手段を付加してあることから、コンテナを降ろすとき自動的に一定高さ位置に浮上させたのち右側方に所定量移動するようになって作業が確実に行え、またコンテナを走行機台上に積み込むときも自動的に所定位置への積み込みが可能になる。
【００３３】
受け部材の上下動を作動させる油圧シリンダーと横移動を起動する駆動スプロケットの起動時には、その上下及び左右移動に連動して警報を発する構成にしてあることから、その移動に連動して警報を発するようにしたので、作業者に注意を喚起して安全で不測の事態が発生しない。
【００３４】
横搬送帯をステップから後方に離間可能に構成するとともに、ステップの終端部には右側方に延出する作用姿勢と機体がわに収納する非作用姿勢とに切替自在にした補助ステップを設け、且つ、横搬送帯の終端部に補助受板を連結し、これを作用姿勢と収納姿勢とに変更可能にしたから、作業終了時等における点検整備作業が容易に行えるのである。
【００３５】
また、ステップの終端部には右側方に延出する作用姿勢と機体がわに収納する非作用姿勢とに切替自在にした補助ステップを設けたので、コンテナ内に収穫物を入れる作業中は作用姿勢の補助ステップにより行動範囲が大になって作業がしやすく、コンテナを地面上に降ろすときには補助ステップが収納して邪魔にならないのである。
【００３６】
更に、横搬送帯の終端部に補助受板を連結し、これを作用姿勢と収納姿勢とに変更可能にしたことによって、収穫物をコンテナ内に入れる作業中において、補助受板上に収穫物の搬送されてきたものを一時貯留することができて作業が容易になるのである。

BACKGROUND OF THE INVENTION
The present invention relates to a root crop harvesting machine that harvests root vegetables such as radishes and carrots grown in a field, and relates to an apparatus for lowering a container storing the dug root vegetables onto the ground.
[0002]
[Prior art]
Conventionally, a pull-out conveyance band that holds the control part on the right side on the traveling machine base and the stem and leaf part of the root vegetable on the left side and pulls it up obliquely upward is arranged, and the start end part is located below the end part of the pull-out conveyance band for conveyance A horizontal transport belt that sends objects to the right side behind the inheritance control section is installed horizontally, and a fork-shaped receiving member for placing the container between the control section and the horizontal transport band and the operator's steps are placed back and forth. A root crop harvesting machine has been developed in which the receiving member can be moved laterally to the right side of the machine body by means of lateral movement means, and the receiving member can be moved up and down relative to the lateral movement means to lower the container onto the ground. Has been. Also, a collection space for the Chinese cabbage harvesting machine and a work place for carrying the Chinese cabbage to the container are provided, and the container is laid out so that the container can be swung over and out and moved up and down, and the fork claws for catching the container are disposed outside the machine body. The support frame that supports the hydraulic cylinder that lifts and lowers the cylinder is placed upright at the rear end of the collection part, and the lift cylinder is slightly extended to lift the container slightly and then rotate 90 degrees. Japanese Patent Application Laid-Open No. 09-163843 discloses that a container is grounded on the ground .
[0003]
[Problems to be solved by the invention]
However, according to this development, when the receiving member for placing the container is laterally moved to the right side of the machine body by the lateral movement means, the container leg is caught on the traveling machine base or laterally moved sideways. When the object is lowered and brought into contact with the ground, there is a problem when the right side of the traveling machine base hits the right side of the traveling machine to cause deformation or damage.Therefore, the present invention can smoothly prevent the container from interfering with the traveling machine base. In addition, it is possible to provide a device that can be safely operated without paying close attention to the operation.
[0004]
[Means for Solving the Problems]
The root vegetable harvesting machine according to the present invention is provided with a pulling and conveying belt (2) for holding the steering part (A) on the right side of the traveling machine stand (1) and holding the stems and leaves of the root vegetable on the left side and pulling it upward and obliquely upward. A starting end is positioned below the terminal end of the pulling and conveying band (2), the conveyed product is inherited, and a horizontal conveying band (3) to be sent to the right side behind the control unit (A) is provided horizontally. ) And the lateral transport belt (3) and a fork-shaped receiving member (5) extending from the front side to the rear side of the traveling machine base (1) on which the container (4) is placed, and for the operator Step (6) is arranged in the front-rear direction, and the receiving member (5) is placed on the traveling platform (1) from the back of the control unit (A) to the left side of the aircraft by lateral movement means (B) . The receiving member (5) can be moved laterally to the right side and the receiving member (5) can be moved up and down with respect to the lateral moving means (B). Since the member (5) is lifted to a certain height on the traveling machine base (1) and then laterally moved to the right by a predetermined distance, the receiving member (5) is grounded on the ground (G). When the receiving member on which the container is placed is laterally moved to the right side of the machine by the lateral movement means, the container leg is caught on the traveling machine base, or the laterally moved side is lowered to fall on the ground. When it is grounded, it can be smoothly and safely lowered onto the ground without hitting the right side of the traveling machine base.
[0005]
Further , when a predetermined amount of harvested material enters the container (4), the container (4) is lifted by the upward movement of the receiving member (5) by the hydraulic cylinder (37), and the movable frame member (21) is switched off. Automatic control when lowering the container by adding restriction means (7) that is turned on by contact with (38) and stops at a fixed height position and restriction means (8) that restricts the lateral movement range (L). Thus, after moving up to a certain height position, it moves to the right by a predetermined amount, so that the work can be performed reliably. In addition, when a container is loaded on the traveling machine stand, it can be automatically loaded at a predetermined position.
[0006]
When the hydraulic cylinder (37) that activates the vertical movement of the receiving member (5) and the drive sprocket (34) that activates the lateral movement are activated, an alarm is generated in conjunction with the vertical and lateral movement. In this case, when the receiving member is moved up and down and moved laterally, an alarm is issued in conjunction with the movement, so that the worker is safe and does not cause any unexpected situation.
[0007]
The lateral transport belt (3) is configured to be able to be separated rearward from step (6), and at the end of step (6), there is an action posture extending rightward and a non-action posture in which the fuselage is housed in a trap. By providing an auxiliary step (6a) that can be switched, and connecting an auxiliary receiving plate (3a) to the terminal end of the lateral transport band (3), which can be changed between an action posture and a storage posture. If the lateral transport belt is configured to be separated from the step backward, the inspection and maintenance work at the end of the work can be easily performed.
[0008]
In addition, an auxiliary step is provided at the end of the step so that it can be switched between a working posture that extends to the right and a non-working posture that the fuselage houses. The posture assist step increases the range of action and facilitates work. When the container is lowered onto the ground, the assist step is accommodated so that it does not get in the way.
