【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の供給装置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。
【０００３】
【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、鱗茎作物を拾い上げて調製機に供給するのに、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、または一括供給装置を装着して供給するか供給手段が講じられていたが、個別供給は手間がかかり又一括供給も機体の側方から複数個拾い集めて供給しなければならないため、拾い集める手間が非能率的であった。
そこで本願発明は、機体の前方で畝幅一杯任意に何処からでも供給可能としたもので、倒伏横向きで鱗茎作物を一括供給すれば、搬送途上で茎を下にした倒立姿勢に姿勢を変更して、従来技術による鱗茎作物の茎葉部と髭根を切除調製する調製部に搬送供給されるので、供給作業が容易になりその利便性を向上改善する事ができ、従来技術の供給搬送装置の不具合を解消し能率向上を図った鱗茎作物調製機の供給装置を提供するものである。
【０００４】
【課題を解決するための手段】
本願発明は、前記の不具合を解消するために、圃場より掘取さ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する鱗茎作物調製機において、複数個の鱗茎作物を倒伏横向きにして一括供給可能とした平ベルト供給装置を機体の最前部に進行方向に対して交差する様に装着して畝幅一杯どこからでも任意に供給し、搬送途上で倒伏横向き姿勢から倒立姿勢に姿勢変更しながら移送できる様にすることで、従来技術による搬送装置の先端に倒立姿勢で一個ずつ供給していたのを、複数個まとめた一括供給にする事で鱗茎作物の茎葉部と髭根を切断調製する調製作業の能率向上を図った。
【０００５】
掘取さ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する鱗茎作物調製機の供給装置に関して、機体の最前部に進行方向に対して交差する様に装着した平ベルト供給装置を機体幅左右方向に周回させ、その下方に左右一対の丸ロ−プベルトからなる支持搬送装置を機体の進行方向に略平行に装着し前後方向に水平周回させて、更に、相互立体交差する様に配設して、該平ベルト供給装置と支持搬送装置の相対位置を活用した上から下への受継行程の中で、一括供給から整列搬送への移行を可能とし、一括供給しながら個別調製ができる様に供給作業の改善を行って調製作業の能率向上を図った。
【０００６】
前記鱗茎作物調製機の供給装置に関して、周回する平ベルト供給装置の搬送作用側終端部とその下方に配設した丸ロ−プベルトを左右対向させてなる支持搬送装置の始端部とを下り傾斜状の誘導樋で連結して、前記平ベルト供給装置と丸ロ−プベルトからなる支持搬送装置の受継ぎを確実にすると同時に、倒伏横向き姿勢で一括供給された鱗茎作物を一個づつ倒立姿勢に移送姿勢を変更して、茎葉部や髭根を切断する調製部に搬送することで、供給能率の向上を行いそれに伴って全体的に調製作業能率の向上を図った。
【０００７】
鱗茎作物調製機の前記供給装置に関して、周回する平ベルト供給装置の搬送作用側終端部に連設した誘導樋を鱗茎作物が個別に整列しながら滑り下りる様に形成し、前記平ベルト供給装置の下方に配置して、同じく平ベルト供給装置の下方に配設された支持搬送装置へ受継ぐ移送行程をコンパクトに構成しながら受継ぎを円滑にした。
【０００８】
鱗茎作物調製機の前記供給装置に関して、周回する平ベルト供給装置と水平周回構造の丸ロ−プベルトを左右対向させてなる支持搬送装置を既述のように立体交差させ、該支持搬送装置の始端側に装着された左右対向し互いに内向きに回転する受動プ−リと同軸回転するように、同プ−リ軸に各々茎誘導板を軸着して、その同調回転によって茎を引き込み、倒伏横向き姿勢で搬送されて来た鱗茎作物を倒立姿勢に姿勢変更しながら移送できるように構成した。
【０００９】
【発明の実施の形態】
以下、本願発明の実施の形態について、図面に基づき実施例を以って説明する。図１は本願発明の要部である平ベルト供給装置の側面図である。図２は同じく本願発明の要部である平ベルト供給装置の平面図である。図３は本願発明に係わる鱗茎作物調製機の全体側面図であり、図４は同じく鱗茎作物調製機の主要部を示した全体正面図である。図５は本願発明に係る鱗茎作物調製装置の仕上げ調製部の伝動機構平面図である。図６は同じく本願発明に係る鱗茎作物調製装置の伝動機構側面図である。
【００１０】
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３及び図４の図示に基づいて説明する。本願発明の鱗茎作物調製機（Ｔ）は走行装置（Ｔ１）上に載置された機台（Ｔ２）に各種搬送装置及び鱗茎作物調製装置（Ｔ３）が搭載され、前記機台（Ｔ２）の後部にエンジン（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。
【００１１】
次に、前記鱗茎作物調製装置（Ｔ３）の構成を図３〜図４に基づいて記述する。
前部に配設された平ベルト供給装置（５）及び粗処理部（１）と後部に配設された仕上げ調製部（２）とに大別されその組合せで構成されている。粗処理部（１）と仕上げ調製部（２）はそれぞれカバ−（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。
【００１２】
又、図１〜図４に示す様に、前記粗処理部（１）の前端部で機体最前部には支持搬送装置（４０）の始端部がカバ−（１３）から突出して延設され、その上方に平ベルト供給装置（５）が機体全幅に亘って進行方向に対して交差する様に装着されている。掘取られた後、圃場に置かれた鱗茎作物を畝幅一杯何処からでも任意に拾い上げて供給することができる様になっている。
【００１３】
更に、図２と図６に示す様に、前記支持搬送装置（４０）の後部下方に茎引張ベルト（６・６）が配置され、該茎引張ベルト（６・６）の始端側のプ−リで実施例では左右一対の茎引張受動プ−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）に左右一対の茎葉粗切刃（６ｆ・６ｆ）を各々軸着し同軸回転する様にして、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。
【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。
圃場より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する鱗茎作物調製機（Ｔ）において、複数個の鱗茎作物を倒伏横向きにして一括供給可能とした平ベルト供給装置（５）を機体の最前部に進行方向に対して交差するように装着し、畝幅一杯どこからでも任意に一括供給して、搬送途上で倒伏横向きにして一括供給された鱗茎作物を誘導樋（５ｄ）によって受継部に移送しながら個別整列させ、支持搬送装置（４０）への受継部で個々に倒立姿勢に姿勢変更するようにすることで、従来技術の様に搬送装置の先端に倒立姿勢で一個ずつ供給したり、又は機体側方から纏めて供給していたのに対して、畝幅どこからでも任意に複数個の鱗茎作物を一括して供給する事ができ、前記鱗茎作物の茎葉部と髭根を切断する調製作業の能率向上が図れる。
具体的にその構成を記述する。本願発明の平ベルト供給装置（５）はロ−ラ軸（５ｆ）と該ロ−ラ軸（５ｆ）に軸着された駆動ロ−ラ（５ｂ）と遊動ロ−ラ（５ｃ）およびこの駆動ロ−ラ（５ｂ）と遊動ロ−ラ（５ｃ）に掛け回された適正幅の平ベルト（５ａ）と誘導樋（５ｄ）及びガイド棒（５ｅ）等で主に構成され、動力によって機体幅左右方向に平ベルト（５ａ）が周回する様に構成され、更に、該平ベルト（５ａ）の伸びを自動的に吸収するコイルばね（５ｇ・５ｇ）が遊動ロ−ラ（５ｃ）側左右に装着されている。該平ベルト供給装置（５）は機体全幅若しくは幅内外適正長さで機体の最前部に装着されている。
そして、前記のロ−ラ軸（５ｆ）に軸着された駆動ロ−ラ（５ｂ）にベルト伝動装置（７）及びチェン伝動装置（８）を介して動力が入力される。尚、該ベルト伝動装置（７）にはテンションプ−リからなる作業クラッチ（７ｄ）が装着され、操作レバ−（図示省略）で作業時と非作業時とで動力の断続操作をする事ができるようになっている。
【００１５】
一方、前記の平ベルト供給装置（５）の下方には、左右一対の丸ロ−プベルト（４１）からなる支持搬送装置（４０）が機体の進行方向に略平行に装着され前後方向に水平周回する様になっていて、該支持搬送装置（４０）の始端部が前記平ベルト供給装置（５）の下方で互いに立体交差するように配設され、平ベルト供給装置（５）への供給作業性と支持搬送装置（４０）の搬送方向とを調和させ、一括供給と整列搬送を可能としている。
【００１６】
また、周回する平ベルト供給装置（５）の移送作用終端部とその下方に配設した前記丸ロ−プベルト（４１）を左右対向させてなる支持搬送装置（４０）の始端部とを下り傾斜状に成形した前記誘導樋（５ｄ）で連結して、平ベルト供給装置（５）と支持搬送装置（４０）の受継ぎを確実にしている。
さらに、平ベルト供給装置（５）の終端部と誘導樋（５ｄ）の始端部の相対的構成は、一括して供給された鱗茎作物を平ベルト供給装置（５）の終端部で個別に落下する様に誘導樋（５ｄ）の始端部が成形され樋状になっているが、機体側は板状の壁を立設して反機体側（機体進行方向側）はガイド棒（５ｅ）を成形装着して、該ガイド棒（５ｅ）と樋底との空間を開放している。前記のガイド棒（５ｅ）は玉部の脱落を防止し、開放された空間からは茎部を外側にはみ出させて、滑り下りる鱗茎作物の流れを円滑にしている。
この様にして、倒伏横向き姿勢で一括供給された鱗茎作物を個別に滑り下ろしながら支持搬送装置（４０）の始端部に誘導し、該支持搬送装置（４０）の始端部で倒立姿勢に姿勢を変更して、茎葉部や髭根を切断する調製部に搬送し、供給能率の向上を行いそれに伴って全体的に調製作業能率の向上を図ったものである。
【００１７】
さらに、周回する平ベルト供給装置（５）の移送作用終端部に連設した前記誘導樋（５ｄ）を平ベルト供給装置（５）の下方に配置して、同じく平ベルト供給装置（５）の下方に配設された支持搬送装置（４０）へ受継ぐ移送空間をコンパクトにした。
図４に図示するように、該平ベルト供給装置（５）と誘導樋（５ｄ）の正面視における相対位置は平ベルト供給装置（５）の終端部から横Ｖ字状に折り返した誘導樋（５ｄ）が下り傾斜になって平ベルト供給装置（５）の下方を支持搬送装置（４０）の始端部まで延設され、鱗茎作物を前記平ベルト供給装置（５）から支持搬送装置（４０）の始端部へ誘導し受継ぎを確実にしている。
【００１８】
更に、図１及び図４に示す様に、水平周回構造の丸ロ−プベルト（４１）を左右対向させてなる支持搬送装置（４０）の始端側には、左右対向し互いに内向きに回転する受動プ−リ（４３・４３）が装着され、各受動プ−リ（４３）と同軸回転するように同プ−リ軸に各々茎誘導板（４４）が軸着されている。該茎誘導板（４４）が丸ロ−プベルト（４１）と同調し回転することによって茎を引き込み、倒伏横向き姿勢で搬送されて来た鱗茎作物の茎側を誘導して、茎側を下方に向けた倒立姿勢に変えて、鱗茎作物の玉部を左右一対の丸ロ−プベルト（４１・４１）で支持し搬送するように構成した。
【００１９】
一方、図３と図５及び図６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、前記支持搬送装置（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。
更に、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）の前部が前記支持搬送装置（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。
【００２０】
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て、該鱗茎作物を倒伏横向き姿勢にして茎葉部を進行方向側に向けて、複数個のものを一括して平ベルト供給装置（５）上に供給する。
【００２１】
そして、一括供給された鱗茎作物は平ベルト供給装置（５）の機体幅左右方向への周回に伴って機体最前部を横送りされ、移送終端部に至った鱗茎作物は一個づつ個別化されて、連設された誘導樋（５ｄ）に転げ落ちて、平ベルト供給装置（５）の下方を横Ｖ字に折返して誘導樋（５ｄ）の下り傾斜に沿って転がり又は滑り下りて支持搬送装置（４０）の始端部に受継がれる。
支持搬送装置（４０）は既述の通り、水平周回構造の丸ロ−プベルト（４１）を左右対向させた構成で、機体中心部を進行方向に対して略平行に前後方向に周回するが、その始端側に左右対向し互いに内向きに回転する受動プ−リ（４３・４３）が装着され、各受動プ−リ（４３）と同軸回転する様に、同プ−リ軸に各々茎誘導板（４４・４４）が軸着されているので、該茎誘導板（４４・４４）が丸ロ−プベルト（４１）と同調し回転することによって茎を引き込み、倒伏横向き姿勢で搬送されて来た鱗茎作物の茎側を誘導して、茎側を下方に向けた倒立姿勢に変えて、鱗茎作物の玉部は左右一対の丸ロ−プベルト（４１・４１）に支持され後方へ搬送される。
さらに、茎葉部は支持搬送装置（４０）の後半に至るとその下方に重層配設された茎引張ベルト（６・６）に挟持され、左右前プ−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。
【００２２】
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３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。
【００２３】
図１及び図６に図示するように、前記支持搬送装置（４０）を構成する搬送ベルトは断面形状が丸形に成形されたロ−プベルト（４１）であり、仕上げ調製部（２）内に配設される駆動プ−リ（４２）と粗処理部（１）先端に設けられた受動プ−リ（４３）と中間プ−リ（４５・４５・・）の間に掛け回されている。
【００２４】
さらに、図２と図３及び図６に示すように、前記支持搬送装置（４０）の下方に層を重ね配設されている前記茎引張ベルト（６・６）を構成する茎引張ベルト体（６ａ・６ａ）はスポンジベルトが用いられ、茎引張駆動プ−リ（６ｂ・６ｂ）と茎引張受動プ−リ（６ｃ・６ｃ）と茎引張中間プ−リ（６ｄ・６ｄ・・）の間に掛け回されている。該茎引張ベルト（６・６）は支持搬送装置（４０）に対して、後方になる程徐々に上下間隔が広がる様に配設している。この様な構成によって、前記の茎引張ベルト体（６ａ・６ａ）で茎葉部を下方に引張った時、鱗茎部は左右一対の丸ロ−プベルト（４１・４１）に支持され、倒立姿勢の向きがより正しくなる様に矯正される。
【００２５】
図３又は図６に示すように、前記茎葉仕上切装置（４）は、左右一対の駆動軸（４ａ・４ａ）上部にそれぞれ回転刃（４ｂ・４ｂ）が軸着されて、両回転刃（４ｂ・４ｂ）の外周縁部が搬送中心線上で一部重なるように配設されている。前記左右一対の駆動軸（４ａ・４ａ）は左右の支持搬送装置（４０・４０）を駆動する伝動ケ−ス（１７）より立設した軸に、自在継手（１８・１８）を介して上方に延設されている。又、前記の回転刃（４ｂ・４ｂ）は図５に図示する様に平面視において、前記左右支持搬送装置（４０・４０）の後部ハ字状広がり部分の後方位置で、前記挟持搬送装置（９）の後部寄りに対応して位置し、図６に図示する様に側面視において、前記の挟持搬送装置（９）の下方に位置して設けられ、この挟持搬送装置（９）における挟持ベルト（９ａ・９ａ）で球形状をした鱗茎部を挟持し搬送しながら、鱗茎作物の茎葉部を両回転刃（４ｂ・４ｂ）によって切断するようにしている。
【００２６】
図６に示すように、前記髭根切断装置（３）は仕上げ調製部（２）において、その前端部上方に配設されている支持枠（３ａ）に支承された髭根起し装置（３ｂ）と髭根切り装置（３ｃ）からなり、この髭根切り装置（３ｃ）は支持枠（３ａ）に上下動自在に連設された平行リンク（３ｄ）の後端に支持枢着されている。
また、前記髭根起し装置（３ｂ）は前記髭根切り装置（３ｃ）に設けた軸受支承部に支承設置されて、前記挟持搬送装置（９）が挟持搬送している鱗茎作物の髭根部を髭根起し装置（３ｂ）で起立整姿して、起立整姿した髭根部を髭根切り装置（３ｃ）で切除するように構成されている。
【００２７】
同じく図３に基づき記述すると、前記の髭根切り装置（３ｃ）は前記平行リンク（３ｄ）の後端に取着するヘッド（３ｆ）と、該ヘッド（３ｆ）に設けた円盤刃駆動ケ−ス（３ｇ）より突出した駆動軸に固設した円盤刃（３ｈ・３ｈ）と、該円盤刃（３ｈ・３ｈ）の前部上側に配設されたゲ−ジ金具（３ｋ・３ｋ）とで構成される。
【００２８】
また、前記平行リンク（３ｄ）と支持枠（３ａ）との間にはコイルばね（３ｎ）を介装し引張して、前記のゲ−ジ金具（３ｋ・３ｋ）が鱗茎作物に当接した際に、その当接荷重でヘッド（３ｆ）が軽くスム−ズに上方に退動できる様にしている。又、前記円盤刃（３ｈ・３ｈ）は、前記茎葉仕上切装置（４）の回転刃（４ｂ・４ｂ）に対して搬送方向上手側または下手側に位置をずらせて配設され、両者の切断タイミングをずらせて、切断負荷の重なりを避け最大負荷を低下する様にしている。
【００２９】
次に、図５及び図６に基づいて伝動機構について記述する。
実施例では、鱗茎作物調製機（Ｔ）を駆動する動力源としてエンジン（Ｅ）が搭載され、該エンジン（Ｅ）の出力軸（Ｅ１）から伝動ベルト（Ｅ２）を介し動力は分配軸（２１）に伝達され、該分配軸（２１）によって各種ベルト搬送装置や茎葉仕上切装置（４）等の駆動系と髭根切断装置（３）の駆動系に分配され、この髭根切断装置（３）の駆動力は伝動ベベルケ−ス（２２）に入力し、内蔵されたベベルギヤを介してカウンタ−軸（２３）へ伝動され、該カウンタ−軸（２３）と縦伝動ベルト（３０）を介し髭根切断装置（３）を駆動する。
更に、前記カウンタ−軸（２３）は平ベルト供給装置（５）にも動力を伝達する。
具体的には、前記カウンタ−軸（２３）から縦伝動ベルト（３０）を介して髭根切断駆動軸（３１）に動力が伝達され、該髭根切断駆動軸（３１）から自在継手（３２）と中継軸（３３）を介して円盤刃駆動ケ−ス（３ｇ）の入力軸（３４）に伝えられ、該入力軸（３４）によってベベルギヤ（３５・３６）を介して円盤刃（３ｈ・３ｈ）を回転駆動すると同時にベベルギヤ（３７・３８）を介して根起しブラシ（３ｂ・３ｂ）を駆動するのである。
また、前記カウンタ−軸（２３）には排葉ベルト（１１）を駆動するロ−ラ（１２）が軸着され、該ロ−ラ（１２）によって前記カウンタ−軸（２３）に平面視で直交する方向に排葉ベルト（１１）が設けられ、該排葉ベルト（１１）は無端状のコンベヤベルトで構成され、切断された排葉を機外に排出するものである。
【００３０】
更に、カウンタ−軸（２３）は機体前端まで延設され平ベルト供給装置（５）を駆動する平ベルト駆動プ−リ（７ｂ）が軸着されている。
本願発明の要部である平ベルト供給装置（５）は前記のベルト伝動装置（７）及びチェン伝動装置（８）を介して、前記ロ−ラ軸（５ｆ）に軸着された駆動ロ−ラ（５ｂ）に動力が伝達され、該駆動ロ−ラ（５ｂ）と遊動ロ−ラ（５ｃ）とに掛回された平ベルト（５ａ）を周回駆動している。
一方、ベルト伝動装置（７）は前記平ベルト駆動プ−リ（７ｂ）と平ベルト入力軸（７ｅ）と該平ベルト入力軸（７ｅ）に軸着された平ベルト入力プ−リ（７ｃ）及び該プ−リ間に掛回されたＶベルト（７ａ）とで主に構成されている。
更に、平ベルト供給装置（５）は前記ベルト伝動装置（７）からチェン伝動装置（８）を介在して駆動されるが、該チェン伝動装置（８）の構成は前記平ベルト入力軸（７ｅ）に軸着された駆動スプロケット（８ｂ）とチェン（８ａ）及び入力スプロケット（８ｃ）から成り、該入力スプロケット（８ｃ）がロ−ラ軸（５ｆ）に軸着されている。
【００３１】
一方、前記の分配軸（２１）からベルト伝動によって、駆動ケ−ス（１７）に内蔵された伝動装置に伝達された動力は、該伝動装置を構成する横入力軸（２６）と左右二組のベベルギヤ（２７・２８）を介して自在継手（１８・１８）によって連動連結される左右一対の駆動軸（４ａ・４ａ）に各々伝達される。
該左右一対の駆動軸（４ａ・４ａ）は各々上方に延設され、その上端に回転刃（４ｂ・４ｂ）を軸着して回転駆動するようにして、茎葉仕上切装置（４）の駆動系が構成されている。
【００３２】
そして、図５に図示する仕上げ調製部（２）の機枠に平面視で前広がりハ字状に装設される左右の搬送駆動ケ−ス（１９・１９）の後部には、図６に図示する如く各々の駆動軸（４ａ・４ａ）が縦向きに嵌挿軸支され、該各駆動軸（４ａ）から搬送駆動ケ−ス（１９・１９）内のギヤ機構（２９・２９）を経て、搬送駆動ケ−ス（１９・１９）の前部に軸支立設されている左右の搬送駆動軸（２０・２０）に動力伝達し、該左右搬送駆動軸（２０・２０）を互いに前側内向きに同速回転させ、該左右搬送駆動軸（２０・２０）に装着された各種の搬送装置を対向面が後方に移送する様に構成されている。
また、前記左右駆動軸（４ａ・４ａ）には茎引張ベルト（６・６）の左右茎引張ベルト体（６ａ・６ａ）を駆動する茎引張駆動プ−リ（６ｂ・６ｂ）が軸着され、受動プ−リ（６ｃ・６ｃ）の下側に同軸回転する茎葉粗切刃（６ｆ）がその外周縁部を搬送中心線上で一部重なるように設けられ互いに対峙して前側内向きに回転するようにしている。
【００３３】
更に、左右搬送駆動ケ−ス（１９・１９）から上方に延出している左右搬送駆動軸（２０・２０）に、支持搬送装置（４０）を駆動する左右両駆動プ−リ（４２・４２）を嵌着固定して、左右両駆動プ−リ（４２・４２）の回転によって前記支持搬送装置（４０）の受動プ−リ（４３・４３）が始端側内向きに回転される。
【００３４】
同じく図６に図示するように、左右の搬送駆動ケ−ス（１９・１９）から上方に延出している前記左右搬送駆動軸（２０・２０）には、左右各々横ベルト伝動装置（１０・１０）の駆動プ−リ（１０ａ・１０ａ）が軸着され各横ベルト伝動装置（１０）を駆動している。
この各横ベルト伝動装置（１０）は左右とも各々搬送駆動軸（２０）に軸着された駆動プ−リ（１０ａ）と前記回転刃（４ｂ）を駆動する駆動軸（４ａ）に遊着された遊動プ−リ（１０ｂ）及び挟持搬送駆動プ−リ（１０ｃ）によって、図５に図示するように平面視にて三角状に掛け回されている。
更に図６の如く、該挟持搬送駆動プ−リ（１０ｃ）の回転軸を上方に延出して同回転軸に挟持搬送入力プ−リ（９ｂ）を軸着し、該挟持搬送入力プ−リ（９ｂ）によって前記の挟持搬送装置（９）に動力が伝えられ、左右一対の挟持ベルト（９ａ・９ａ）を同速で互いに始端側内向きに回転駆動し対向面が後方移動するように構成されている。
【００３５】
【発明の効果】
本願発明は、以上説明したような構成と実施の形態によって、次のような効果を奏するものである。
