【発明の属する技術分野】
本発明は、圃場から鱗茎作物収穫機等により採取されて畝上に置かれた鱗茎作物を拾い上げて、茎葉部と髭根を切断して調製するか、又は定置仕様として同様の処理調製を行う鱗茎作物調製機に関するものである。
【０００２】
【従来の技術】
従来から、鱗茎作物収穫機等により圃場から鱗茎作物を採取し圃場に放置して乾燥させ、その後、畝に沿って鱗茎作物調製機を走行させながら鱗茎作物を拾い上げて、該調製機に直接又は供給搬送装置を介して供給し、鱗茎作物の茎葉部と髭根を切除する収穫作業体系や定置的に装置機器として一連の装置を組合せた大形調製機において、鱗茎作物の茎葉部や髭根の調製技術が既に色々な形で公知となっている。（例えば、特許文献１参照）

【発明が解決しようとする課題】
しかし、従来の技術においては、掘取された鱗茎作物を拾い上げて、搬送装置の先端部から茎を下にした倒立姿勢で一個ずつ供給するか、または供給装置を装着して一括供給するかの手段が講じられ、この搬送装置に茎引張装置を装備したものが知られているが、前記の搬送装置と茎引張装置の速度バランスや配置構成等幾つかの要因が係って玉部が傾いたりして、茎や髭根を切断する時の玉部の姿勢が不安定で茎や髭根の仕上げ状態がバラツキ、玉部への損傷が多々生じると言う不具合があった。
そこで本願発明は、収穫した鱗茎作物を無造作に一括供給を可能とし、たとえ茎の向きが不特定方向に乱れていても、搬送途上で茎を下にした倒立姿勢に強制的に変更しながら仕上げ調製部に搬送供給するもので、茎や髭根を切断する時の姿勢を茎が下方垂直に安定するようにし、玉部の損傷を防止して従来技術における供給搬送上の不具合を解消し、仕上げ状態の向上を図った鱗茎作物調製機を提供するものである。
【０００５】
【課題を解決するための手段】
本願発明は、前記の従来技術の不具合を解消するために、請求項１においては、掘取られた鱗茎作物を整列搬送装置（Ｈ）に供給して、この鱗茎作物の茎葉部と髭根を切断分離する鱗茎作物調製装置（Ｔ３）を備えた鱗茎作物調製機において、平面視で機体中心部に前後方向に配設した前記整列搬送装置（Ｈ）の下部に設けた２連構造からなる前部を前記鱗茎作物の茎葉部を挟持する左右一対の茎引きベルト体（６０ａ）・（６０ａ）の進行につれて前記鱗茎作物の茎葉部を下方に引下げて球部を前記整列搬送装置（Ｈ）に密着させて垂直姿勢で搬送する茎引きベルト装置（６０）を前記整列搬送装置（Ｈ）に対して傾斜を付け相互間隔を後方に向け漸次拡大して設け、その後部に前記茎引きベルト装置（６０）で一定姿勢にした前記鱗茎作物を前記整列搬送装置（Ｈ）とともに水平方向に搬送する茎送りベルト装置（６１）を前記整列搬送装置（Ｈ）と略平行に設け、前記茎引きベルト装置（６０）と前記茎送りベルト装置（６１）とを２連プ−リである連結プ−リ（６ｇ）を介して茎引張装置（６）を構成したものである。
【０００６】
請求項２においては、前記整列搬送装置（Ｈ）の速度に対して前記茎引きベルト装置（６０）はやや早く、前記茎送りベルト装置（６１）は略同速に設定した前記茎引きベルト装置（６０）の搬送終端部と前記茎送りベルト装置（６１）の搬送始端部とを２連プ−リである連結プ−リ（６ｇ）を介して連設され且つ、前記茎引張装置（６）が鱗茎作物を挟持する搬送面を前記整列搬送装置（Ｈ）の後部下方から前記茎葉部を切断する茎葉仕上切装置（４）間に渡って設けたものである。
【０００７】
請求項３においては、機枠に平面視で前広がりのハ字状に装設された左右一対の搬送駆動ケ−ス（１９）・（１９）の前部に立設した搬送駆動軸（２０）に軸着した駆動プ−リ（１０ａ）とその後部に立設した駆動軸（４ａ）の下方側に前記茎引張装置（６）を駆動する茎送り駆動プ−リ（６ｂ）とその上方に遊動プ−リ（１０ｂ）を装着しさらに、前記鱗茎作物の球部を挟持搬送する挟持搬送装置（９）を駆動する挟持搬送入力プ−リ（９ｂ）を軸着した回転軸の下端に挟持搬送駆動プ−リ（１０ｃ）を設け、前記駆動プ−リ（１０ａ）と前記遊動プ−リ（１０ｂ）さらに、挟持搬送駆動プ−リ（１０ｃ）とで平面視で三角状にベルトを巻き掛けした横ベルト伝動装置（１０）を側面視で前記挟持搬送装置（９）の下方で前記茎引張装置（６）上方に設けたものである。

【０００９】
本願発明の実施例である鱗茎作物調製機（Ｔ）の全体構成について図４又は図５の図示に基づいて説明する。
本願発明に係る鱗茎作物調製機（Ｔ）は走行装置（Ｔ１）を有し、該走行装置（Ｔ１）上に載置された機台（Ｔ２）に螺旋供給装置（５）や整列搬送装置（Ｈ）および鱗茎作物調製装置（Ｔ３）が一体的に搭載され、前記機台（Ｔ２）の後部にはエンジン（Ｅ）と走行伝動装置（Ｔ４）および操縦ハンドル（Ｔ５）等が配設されている。
そして鱗茎作物調製装置（Ｔ３）と操縦ハンドル（Ｔ５）の間に左右切替え自在の排出シュ−タ−（１６）が配設され、その左右下端には折畳み収納可能なる排出口（１６ａ）が設けてある。
【００１０】
次に、前記鱗茎作物調製装置（Ｔ３）の構成を図４又は図５に基づいて記述する。
本願発明の鱗茎作物調製装置（Ｔ３）は前部に配設された螺旋供給装置（５）と粗処理部（１）および後部に配設された仕上げ調製部（２）とで構成されている。
粗処理部（１）と仕上げ調製部（２）は夫々カバ−（１３）・（１４）によって覆われ、該粗処理部（１）のカバ−（１３）の上面高さは仕上げ調製部（２）のカバ−（１４）の上面高さより低く配置構成して、前記粗処理部（１）を覆っているカバ−（１３）の上面には、機体幅方向中央に進行方向と平行に通路溝が形成されている。
【００１１】
又、図４又は図５に示す様に、前記粗処理部（１）の前端部には左右一対のブラシ部付整列ロ−ラ（４０）・（４０）の前部がカバ−（１３）から突出し延設され、その上方に一部重合して螺旋供給装置（５）が機体最前部幅一杯に連設されている。
掘取られた後、圃場に置かれた鱗茎作物を何処からでも任意に拾い上げて無造作に供給することができる様になっている。
【００１２】
さらに、図１又は図２又は図５と図６に示す様に、左右のブラシ部付整列ロ−ラ（４０）・（４０）の後部下方に茎引張装置（６）・（６）が左右一対で配置され、各茎引張装置（６）は２分割され前部を茎引きベルト装置（６０）とし後部を茎送りベルト装置（６１）とした２連構成をなし、各茎引きベルト装置（６０）の構成は茎引きベルト体（６０ａ）が茎引き受動プ−リ（６ｃ）と２連プ−リである連結プ−リ（６ｇ）の大径側に巻掛けられ、前記ブラシ部付整列ロ−ラ（４０）に対して傾斜し相互間隔を後方へ漸次拡大し、周回速度を前記ブラシ部付整列ロ−ラ（４０）に対して速めに調整し装着されている。
一方、茎送りベルト装置（６１）は茎送りベルト体（６１ａ）が連結プ−リ（６ｇ）の小径側と茎送り駆動プ−リ（６ｂ）との間に巻掛けられ前記ブラシ部付整列ロ−ラ（４０）に対して平行にして同速に調整し装着されている。
【００１３】
前記始端側のプ−リで実施例では左右一対の茎引き受動プ−リ（６ｃ）・（６ｃ）を軸着するプ−リ軸（６ｅ）・（６ｅ）を下方に延出させ、該各プ−リ軸（６ｅ）に茎葉粗切刃（６ｆ）を各々軸着し同軸回転するようにして且つ左右一対に構成してあり、茎葉の通路側に向かって各々始端側内向きに回転するようになっている。
更に、前記各プ−リ軸（６ｅ）は下方に延出され増速チェン装置（４４）を介して茎押羽根（４５）を駆動する。
【００１４】
ここで、本願発明の要旨を図１〜図３に基づいて記述する。
掘取られた鱗茎作物を搬送装置に供給して、該搬送装置の搬送過程で鱗茎作物の茎葉部と髭根を切断分離する鱗茎作物調製装置（Ｔ３）を備えた鱗茎作物調製機（Ｔ）の供給搬送装置において、該供給搬送装置の下部に茎引張装置（６）を設け、該茎引張装置（６）を分割し２連構造にして、前側を茎引きベルト装置（６０）として該茎引きベルト装置（６０）で姿勢を整え、後側を茎送りベルト装置（６１）として該茎送りベルト装置（６１）で所定の倒立姿勢に定着して整列搬送し茎や髭根の切断時の姿勢を茎下方垂直に安定させて玉部の損傷を防止するようにして、従来技術の供給搬送上の不具合を解消し仕上げ状態の向上を図ったものである。
一方、図４と図５に示すように前記供給搬送装置は螺旋搬送装置（５ｂ）を内蔵したホッパ−（５ａ）を装備した螺旋供給装置（５）を機体の最前部に一体的に連設して、鱗茎作物を茎の向きや姿勢に拘らず任意の姿勢で供給し、螺旋搬送装置（５ｂ）によって強制的に一個ずつ整列搬送装置（Ｈ）に受継がせるが、この整列搬送装置（Ｈ）は左右一対のブラシ部付整列ロ−ラ（４０）・（４０）からなり、このブラシ部付整列ロ−ラ（４０）・（４０）は機体の進行方向に対して略平行にして相互内向きに回転し、且つ、ロ−ラ体（４１）の全外周面をブラシ状に植毛して、更に終端部を除きゴム或は合成樹脂等の弾性体からなる螺旋体（５０）を前記ブラシ部と一定ピッチで重着した構成になっていて、前記螺旋供給装置（５）の後部下方に重合連設して、任意の供給姿勢から所定の倒立姿勢に整列しながら移送できる様に構成してある。
【００１５】
更に、図１〜図３及び図４により具体的にその構成を記述する。
既述した左右一対のブラシ部付整列ロ−ラ（４０）・（４０）の後部下方に重層し配設されている左右茎引張装置（６）・（６）の茎引きベルト体（６０ａ）・（６０ａ）及び茎送りベルト体（６１ａ）・（６１ａ）はスポンジベルトが用いられ、茎引きベルト体（６０ａ）が茎引き受動プ−リ（６ｃ）と２連プ−リである連結プ−リ（６ｇ）の大径側に巻掛けられ、前記ブラシ部付整列ロ−ラ（４０）に対して傾斜し相互間隔を後方へ漸次拡大し、周回速度を前記ブラシ部付整列ロ−ラ（４０）に対して速めに調整し装着されている。
一方、茎送りベルト装置（６１）は茎送りベルト体（６１ａ）が連結プ−リ（６ｇ）の小径側と茎送り駆動プ−リ（６ｂ）との間に巻掛けられ前記ブラシ部付整列ロ−ラ（４０）に対して平行にして同速に調整し装着されている。
この様な構成によって、前記の茎引きベルト体（６ 0 ａ）・（６ 0 ａ）で茎葉部を挟持し搬送が進行するにつれて茎を下方に引下し玉部をブラシ部付整列ロ−ラ（４０）・（４０）に密着させて搬送性能を安定させるようにして、倒立姿勢の向きがより正しくなるように矯正される。
一方、前記の茎送りベルト装置（６１）・（６１）は前記ブラシ部付整列ロ−ラ（４０）・（４０）略平行に装着して、前記の茎引きベルト装置（６０）・（６０）から受継いだ搬送姿勢を維定着しながら仕上げ調製部に整列搬送して、茎や髭根の切断分離を円滑にするように構成した。
【００１６】
一方、本願発明に係る螺旋供給装置（５）は略機体幅一杯のホッパ−（５ａ）を機体最前部に一体的に連設して、蝶番を介在して回動可として、該ホッパ−（５ａ）には螺旋搬送装置（５ｂ）を回転自在に内蔵して構成しているが、該螺旋供給装置（５）はホッパ−（５ａ）の外壁に固着した支持金具（５ｅ）と機台（Ｔ２）を伸縮ステ−（５ｄ）で連結し、該伸縮ステ−（５ｄ）の伸縮調整によって蝶番を取着支点として上下回動自在に枢着され、一方、螺旋搬送装置（５ｂ）は一本の回転軸（５ｃ）のまわりに螺旋歯を固着して、該回転軸（５ｃ）の回転によって無造作に供給された鱗茎作物を出口に向かって移送するが、前記回転軸（５ｃ）はベルト伝動装置（７）及びチェン伝動装置（８）を介して動力によって駆動される。
該ベルト伝動装置（７）は左ブラシ部付整列ロ−ラ（４０）に直結していて、該左ブラシ部付整列ロ−ラ（４０）のロ−ラ軸に軸着した入力プ−リ（７ｂ）と出力プ−リ（７ｃ）及び両プ−リに巻掛けたベルト（７ａ）から構成され、更に出力プ−リ（７ｃ）を一端に軸着している中間軸の他端には入力スプロケット（８ｂ）が軸着されていて、前記チェン伝動装置（８）を連結している。
該チェン伝動装置（８）は前記入力スプロケット（８ｂ）と出力スプロケット（８ｃ）及び両スプロケットに巻掛けられたチェン（８ａ）とから構成され、前記螺旋供給装置（５）に動力を伝達している。
【００１７】
上記左右一対に構成された茎引張装置（６）・（６）の速度構成は、前記ブラシ部付整列ロ−ラ（４０）の速度に対して、各茎引張装置（６）の前側と後側を連結プ−リ（６ｇ）を介して前側の茎引きベルト装置（６０）はやや早く、後側の茎送りベルト装置（６１）は略同速に設定して、前記ブラシ部付整列ロ−ラ（４０）だけでは鱗茎作物の姿勢が傾き加減になるのを、茎引きベルト装置（６０）で茎を引きながら玉部の姿勢を修正することで、略垂直に倒立させ搬送姿勢を整えるようにして、連設した茎送りベルト装置（６１）に受継ぎ玉部は後続する挟持搬送装置（９）に挟ませ、前記茎送りベルト装置（６１）では茎を引下げずに水平に前記ブラシ部付整列ロ−ラ（４０）と同速同調して鱗茎作物の垂直姿勢を維持させ、挟持搬送装置（９）が玉部を挟んだら茎を下方に引っ張らない様にして前記挟持搬送装置（９）のベルト外れや傷つきを回避する様にした。
【００１８】
更に、図２又は図３又は図４に示すように、左右一対のブラシ部付整列ロ−ラ（４０）・（４０）の前方に螺旋供給装置（５）を連設して、該螺旋供給装置（５）とブラシ部付整列ロ−ラ（４０）・（４０）の連結部に鱗茎作物の姿勢を修正する上向き及び横向き茎に兼用される茎反転ガイド（４３）を配設して、例え茎が不特定方向をバラバラに向いていても、所定の向きに反転して併設のブラシ部付整列ロ−ラ（４０）・（４０）が鱗茎作物の茎を下向きに引き込み易くして姿勢修正を容易にした。
即ち、前記の茎反転ガイド（４３）は無造作に供給されて不特定方向を向いた複数個の鱗茎作物の茎を一個ずつ所定の向きに反転させて、前記左右一対のブラシ部付整列ロ−ラ（４０）・（４０）に受継ぎ、既述の様にして倒立姿勢に姿勢変更をし易くして整列搬送を確実にしている。
【００１９】
又、前記供給装置は螺旋搬送装置（５ｂ）を内蔵したホッパ−（５ａ）からなる螺旋供給装置（５）であり、前記螺旋搬送装置（５ｂ）の螺旋歯（５ｅ）の端面をゴム又は合成樹脂等の緩衝材で被覆して、ホッパ−（５ａ）に鱗茎作物を投入しても損傷しないようにした。
図２又は図３に図示するように、ホッパ−（５ａ）の出口から螺旋搬送装置（５ｂ）によって押出された鱗茎作物は所定の倒立姿勢で受継がれるものもあれば、茎が上向きや横向きで受継がれるものもあり、所定の倒立姿勢のものは反転の必要がなく其のまま搬送されるが、上向きや横向きで受継がれるものは左右のブラシ部付整列ロ−ラ（４０）・（４０）上を搬送されながら茎反転ガイド（４３）に当接すると流れを阻害して玉部の進行につれて茎は流れの後方に反転倒伏するので、該反転倒伏した茎を左右のブラシ部付整列ロ−ラ（４０）・（４０）が引き込んで強制的に下方に向けさせ所定の倒立姿勢を確実にする。
【００２０】
さらに、図２及び図３に仮想線で図示したごとく、螺旋搬送装置（５ｂ）を内蔵したホッパ−（５ａ）とブラシ部付整列ロ−ラ（４０）・（４０）の連結部に装着した前記の茎反転ガイド（４３）はトルク（ねじり）ばね（５ｆ）を介在して上下動及び左右回動を夫々可能なるように装着してあり、鱗茎作物の玉の大きさに順応して当接時の抵抗をやわらげる事で、鱗茎作物を損傷する事なく円滑な流れの中で倒立姿勢に姿勢変更しながら仕上げ調整部（２）へと整列搬送するように構成した。
【００２１】
又、螺旋搬送装置（５ｂ）を内蔵したホッパ−（５ａ）とブラシ部付整列ロ−ラ（４０）・（４０）の連結部に装着した前記茎反転ガイド（４３）に対して後方近傍にて相対的位置に、ゴム又は合成樹脂等の弾性体からなる左右一対の茎押羽根（４５）・（４５）を装備して、該茎押羽根（４５）・（４５）を左右相互内向きに回転自在にし、その周速を搬送速度より数倍も増速して装着する事で、前記茎反転ガイド（４３）で十分反転できなかった鱗茎作物の横向き又は上向きの茎の部分或いは玉の表皮部を押して玉の進行方向に茎を反転させる事によって茎の向きを搬送方向に略平行に倒伏させ、左右ブラシ部付整列ロ−ラ（４０）・（４０）が引き込み易くして茎を強制的に下方に向かし、所定の倒立姿勢を確実にすることができるように構成した。
【００２２】
一方、図４又は図５に図示したように、仕上げ調製部（２）にてカバ−（１４）の内側には、前記ブラシ部付整列ロ−ラ（４０）・（４０）の上方に位置し、球形をした鱗茎作物の鱗茎部を挟持搬送する挟持搬送装置（９）が配設され、更に挟持搬送装置（９）の上方に髭根切断装置（３）が配設してあり、前記挟持搬送装置（９）の下方には茎葉仕上切装置（４）が配設してある。
さらに、図４又は図５に図示するように、前記の挟持搬送装置（９）は左右一対の挟持ベルト（９ａ）・（９ａ）によって挟持搬送通路を形成し、該挟持搬送装置（９）の前部が前記ブラシ部付整列ロ−ラ（４０）・（４０）の後部上方にラップするように配設され、該挟持搬送装置（９）の後端には排出部（１５）が配設されている。
【００２３】
以上のような配置構成の鱗茎作物調製機（Ｔ）において、該鱗茎作物調製機（Ｔ）は畝の肩上を走行して、作業者は畝上に置かれた鱗茎作物を拾い上げ又既に圃場又は集荷場で集められた鱗茎作物群を、移動又は定置的に鱗茎作物を無造作に茎葉部を揃たり向きを規制する事なく螺旋供給装置（５）に供給するが、螺旋供給装置（５）とブラシ部付整列ロ−ラ（４０）・（４０）の連結部に配設した茎反転ガイド（４３）によって、例え茎が不特定方向をバラバラに向いていても、所定の向きに反転して併設のブラシ部付整列ロ−ラ（４０）・（４０）が鱗茎作物の茎を下向きに引き込み、茎引張装置（６）分割した前側の茎引きベルト装置（６０）で姿勢を整え、後側の茎送りベルト装置（６１）で所定の倒立姿勢に定着して整列搬送し茎や髭根の切断時の姿勢を茎下方垂直に安定させて玉部の損傷を防止するようにして、従来技術の供給搬送上の不具合を解消し仕上げ状態の向上を図ったものである。
【００２４】
そして、一括供給された鱗茎作物は螺旋供給装置（５）内を螺旋搬送装置（５ｂ）によって出口側に移送され、該出口から一個ずつ個別化されて連設されたブラシ部付整列ロ−ラ（４０）・（４０）に転げ落ちて、該ブラシ部付整列ロ−ラ（４０）・（４０）の始端部に受継がれ、強制的に引き出され連設された茎反転ガイド（４３）によって茎の向きが上向きや横向きのものは茎が反転されて下向きになり整列搬送されるのである。
この時、前記茎引きベルト体（６０ａ）・（６０ａ）で茎葉部を挟持し搬送が進行するにつれて茎を下方に引下し玉部をブラシ部付整列ロ−ラ（４０）・（４０）に密着させて搬送性能を安定させ、倒立姿勢の向きがより正しくなるように矯正される。
一方、前記の茎送りベルト装置（６１）・（６１）は前記ブラシ部付整列ロ−ラ（４０）・（４０）と略平行に装着して、前記の茎引きベルト装置（６０）・（６０）から受継いだ鱗茎作物の搬送姿勢を維持し、茎を下にした垂直倒立姿勢で仕上げ調製部（２）に整列搬送して、茎や髭根の切断分離を円滑にするように構成した。
【００２５】
即ち、ブラシ部付整列ロ−ラ（４０）だけでは鱗茎作物の姿勢が傾き加減になるので、茎引きベルト装置（６０）で茎を引下げながら玉部の姿勢を修正する事で、略垂直に倒立させ搬送姿勢を整える様にして、連設した茎送りベルト装置（６１）に受継ぎ玉部は後続する挟持搬送装置（９）に挟ませ、前記茎送りベルト装置（６１）では茎を引下げずに水平に前記ブラシ部付整列ロ−ラ（４０）と同速同調して鱗茎作物の垂直姿勢を維持させ、挟持搬送装置（９）が玉部を挟んだら茎を下方に引っ張らない様にして前記挟持搬送装置（９）のベルト外れや傷つきを回避する様にした。
【００２６】
更に、螺旋搬送装置（５ｂ）の螺旋歯（５ｅ）の端面をゴム又は合成樹脂等の緩衝材で被覆して、ホッパ−（５ａ）に鱗茎作物を投入しても損傷しないようにして出口から押出すが、押出された鱗茎作物の茎が上向きや横向きで左右のブラシ部付整列ロ−ラ（４０）・（４０）に受継がれたものは、該左右のブラシ部付整列ロ−ラ（４０）・（４０）上を搬送されながら茎反転ガイド（４３）に当接すると茎部の流れが一時的に阻止され、玉部の搬送が進行するにつれて茎は流れの後方に反転倒伏されるが、茎反転ガイド（４３）がトルク（ねじり）ばね（５ｆ）を介在して上下動及び左右回動を夫々可能なるように装着してあるので、鱗茎作物の玉の大きさに順応して当接時の抵抗をやわらげる事で、鱗茎作物を損傷する事なく円滑な流れの中で倒立姿勢に姿勢変更しながら仕上げ調整部（２）へと整列搬送するように構成した。
【００２７】
一方、各ブラシ部付整列ロ−ラ（４０）は既述の通り、円筒形ロ−ラ体（４１）の全外周面をブラシ状に植毛し、更にゴム又は合成樹脂等の弾性体からなる螺旋体（５０）が終端部を除き先端部から一定ピッチで重着固設され、左右一対で整列搬送装置（Ｈ）を構成し機体中心部を進行方向に対して略平行に前後方向に配設されている。
そこで、前記螺旋供給装置（５）より一個ずつ供給される鱗茎作物は、例え倒伏横向き姿勢であっても、既述の如く一対のブラシ部付整列ロ−ラ（４０）・（４０）の相互内向き回転によって茎を下向きに引き込み強制的に倒立姿勢にし、また全外周面に植毛したブラシによって全搬送行程中下向き引き込み作用が働き整然とした倒立姿勢で搬送する。
その時、整列搬送に必要な距離を出来るだけ短く構成し、その上で無造作に一括供給しながら個別調製作業ができる様にして、鱗茎作物調製機（Ｔ）の構成をコンパクトなものにしてある。
入力構成は図４又は図５又は図６に示すように、左右搬送駆動軸（２０）・（２０）に各々ブラシ部付整列ロ−ラ（４０）・（４０）を駆動する一対のベベルギヤを内蔵した左右一対のベベルボックス（４２）・（４２）を取付けて、該左右一対のベベルボックス（４２）・（４２）の介在で前記ブラシ部付整列ロ−ラ（４０）・（４０）が相互内向き回転される。
【００２８】
この様にして、左右一対のブラシ部付整列ロ−ラ（４０）・（４０）によって茎側を下方に向けた倒立姿勢で整列搬送されて来た鱗茎作物は左右一対のブラシ部付整列ロ−ラ（４０）・（４０）に巻掛け固着したゴム又は合成樹脂等の弾性体からなる左右螺旋体（５０）・（５０）によって更に機体後方へ搬送される。
そして、茎葉部は左右一対のブラシ部付整列ロ−ラ（４０）・（４０）の後半に至るとその下方に重層配設された茎引きベルト（６０）・（６０）に茎葉が挟持され、左右受動プ−リ（６ｃ）・（６ｃ）と同軸回転する左右茎葉粗切刃（６ｆ）・（６ｆ）によって長く伸びた茎葉は粗切断され、姿を整えて倒立姿勢のまま更に後方へ搬送される。
【００２９】
そして、鱗茎作物は粗処理部（１）を搬送される間、通路溝（図示省略）の左右両側の傾斜面にガイドされ適正な倒立姿勢を維持しながら搬送され、仕上げ調製部（２）に至ると挟持搬送装置（９）によって鱗茎作物の鱗茎部は挟持搬送される。
この搬送過程の中で、髭根部は髭根切断装置（３）によって切断され、茎葉部は茎葉仕上切装置（４）によって切断される。
髭根部および茎葉部を切断された鱗茎部は、前記の挟持搬送装置（９）の終端部で挟持を解かれ、排出部（１５）を転がり出て排出シュ−タ−（１６）を介して機外に排出される。
尚、図４に示すように前記排出部（１５）は挟持ベルト（９ａ）・（９ａ）の後部下方から排出シュ−タ−（１６）までの間にガイド杆（１５ａ）（１５ａ）・・が前後方向に後下りに傾斜して配設されてある。
