Description

【０００１】
【発明の属する技術分野】
本発明は、栽培圃場で抜き取った玉ねぎやニンニク等の鱗茎作物を、調製機体の供給口より供給し、鱗茎部から茎葉及びひげ根を除去して出荷姿に調製し搬出口に搬出する鱗茎作物調製機のひげ根切断装置に関する。
【０００２】
【従来の技術】
鱗茎作物の中で代表的な玉ねぎの場合を例にすると、栽培圃場で抜き取った玉ねぎは、畦の上に並べ数時間自然乾燥させ調製作業に入るか、茎葉部で適当量束ね乾燥場へ搬入し乾燥後調製作業に入るか、何れの場合もその調製作業は、ハサミを使い手作業で鱗茎部より茎葉とひげ根を２工程で切断し、除去した茎葉やひげ根と混合しないように分けながら鱗茎部を収穫するのが一般的で、早急な圃場よりの搬出労力や多くの手作業、特に、ひげ根の切断では気を使う丁寧な作業を必要としている。
尚、このひげ根切断作業を、走行車に装着した調製装置で行なうのは公知としてあるが、収穫物の品質に重大な影響をおよぼすひげ根切断位置の精度を高く維持できる装置としては、公知例では切断直前のひげ根ガイドや位置決め等が無くその点十分な構造とはいえない。
例えば、特開平８−２８０２１９号公報の通りである。
【０００３】
【発明が解決しようとする課題】
鱗茎作物調製機は、搬入条件の悪い圃場や、変形小区画で分散した圃場での作業に多く要望されており、しかも小形であっても短時間で処理できる能率と品質確保のための高い精度が要求される。
これは、鱗茎作物を裏作として栽培する場合が多く、直後に控えている表作の植付けまでには収穫を終えなければならず、又、その地域の収穫時期の集中により近所の熟練した農家の人手を確保するのは困難なためである。
従って、鱗茎作物調製機の課題の一つとしては、ひげ根切断装置を、誰が作業しても、鱗茎作物を調製機に供給することにより、ひげ根切断位置の精度を高く維持できる構造に纏めることである。
【０００４】

【００１０】
まず、本発明を装備した鱗茎作物調製機の全体の構成を、図１、図２、図３を用いて説明する。
以下は、代表的な鱗茎作物である玉ねぎを例に、調製機体の下方に小径車輪を取り付けた手押し式の場合について説明する。
全体の構成は、動力源１０・調製機体４・鱗茎搬出部８・車輪部３・フレーム体５０で、更に調製機体４は、鱗茎搬送装置５・茎葉処理装置６・ひげ根切断装置７及び固定カバー５３・サイドカバー５４を配置して構成している。
【００１１】
本発明を装備した鱗茎作物調製機の動きを説明すると、動力源１０の回転力を供給口４０付近側面に配置した主クラッチレバー４４を「入」にし鱗茎作物搬送装置５・茎葉処理装置６・ひげ根切断装置７の各伝動部を回転駆動するとともに、供給口４０より鱗茎作物の葉を下向きにし鱗茎部を鱗茎搬送装置５の対向する鱗茎搬送帯６０Ｌ・６０Ｒに乗せると共に茎葉を茎葉処理装置６の茎葉整列帯６２Ｌ・６２Ｒに挟持させれば、適当な力で茎葉を下に引き鱗茎部の位置決めを行ない後方の搬出口４３まで搬送する。
また、茎葉処理装置６の前端部で鱗茎部の荒切断と後端部で仕上げ切断を行なう。
そして、この鱗茎保持状態でひげ根切断装置７ではひげ根調製・鱗茎と接当し切断位置決め・切断・ひげ根拡散を行ない、鱗茎搬出部８では切替え板８１により機体の左又は右に調製された鱗茎を排出する動きをする。
【００１２】
動力源（この場合エンジン）１０は、フレーム体５０上面で鱗茎搬出部８に隣接した位置に締結固定され、エンジンプーリ１１から伝えられた回転力は、主クラッチベルト１２を介して鱗茎搬出部８下方でフレーム５０上面に固定したユニット軸受１７と分配軸ベベルケース１８とで軸支した分配軸１４に固着した分配軸プーリ１５ａに動力を伝達し、その動力の断続は供給口４０付近側面に配置した主クラッチレバー４４を操作することにより主テンションアーム１３を動かして行ない、エンジン回転調節はハンドル２１に固着したアクセルレバー２３を操作して行なう。
【００１３】
調製機体４の鱗茎搬送装置５は、側面視で、調製機体４の上下方向ほぼ中央位置で水平に架設しており、供給口４０から搬出口４３付近まで延設した一対の対向する鱗茎搬送帯６０Ｌ・６０Ｒと、この上方に、並列的にひげ根切断装置７の下方から搬出口４３付近まで延設した幅広の搬送帯で一対の対向する鱗茎挟持搬送帯６３Ｌ・６３Ｒを配置し、その動力伝達は分配軸プーリ１５ｂ、分配軸ベルト１６、搬送駆動ケース４５を介して幅広プーリ４８Ｌ・４８Ｒ、丸溝プーリ４９Ｌ・４９Ｒにより伝動連結状態で鱗茎が供給口４０から搬出口４３の方向へ移動するよう構成した構造である。
【００１４】
調製機体４の茎葉処理装置６は、側面視で、鱗茎搬送装置５の下方にあり、ひげ根切断装置７終端付近の下方に配置した茎葉処理駆動ケース４６ａの出力軸４６ｂＬ・４６ｂＲ下方から供給口４０付近では鱗茎搬送帯６０に近接するよう後ろ下がり斜めに延設した一対の対向する茎葉整列帯６２Ｌ・６２Ｒを配置し、出力軸４６ｂＬ・４６ｂＲ側には鱗茎搬送帯６０に近接した位置に仕上げ切断を行なう茎葉切断刃６５Ｌ・６５Ｒを一部重接状態で回転係合すると共に、供給口４０側には荒切断を行なう葉部切断刃６４Ｌ・６４Ｒを下方で一部重接状態とし右葉部切断刃６４Ｒ下面に切断補助板６９を設け回転係合し、その動力伝達は分配軸ベベルケース１８、中間軸５７、ベベルケース５８を介して茎葉処理駆動ケース４６ａに伝動連結し、鱗茎作物が供給口４０から搬出口４３の方向に移動するよう構成した構造である。
【００１５】
本発明を織り込んだ調製機体４のひげ根切断装置７については、図４、図５、図６、図７、図８を用いて説明する。
ひげ根切断装置７は、根切駆動ケース４７、ひげ根調製体６７Ｌ・６７Ｒひげ根切断刃６６Ｌ・６６Ｒ根切ガイド７０、リンク取付体７３Ｌ・７３Ｒで構成している。

【００１６】
ひげ根調製体６７は、円筒軸６７ａの外周に適当に植毛して円筒ブラシを形成した対向し外接する一対のひげ根調製体６７Ｌ・６７Ｒで構成し、根切駆動ケース４７の前向きに突出する２本の軸に回転係合し、中央外接部で下から上方向に回転して搬送してきた鱗球のひげ根を整えるものである。
ひげ根切断刃６６は、薄い円盤状の対向し一部重接する一対のひげ根切断刃６６Ｌ・６６Ｒで構成し、根切駆動ケース４７の下向きに突出する２本の軸に回転係合し、中央重接部で前から後方へ噛み込み方向に回転し、搬送してきた鱗球のひげ根を切断するものである。
掻き出し体７２は、対向して接する長さの突起部を一カ所有する一対の弾性体で、ひげ根切断刃６６Ｌ・６６Ｒ上面に近接し回転係合した構成であり、切断したひげ根等をカッター上面より飛散排出するものである。
【００１７】
次に、根切ガイド７０は、接当部に２つの円弧の組み合せて略釣針形状に形成した（図７の実施例はこれ等が重なった１つの円弧）一対の棒状のガイド体７０ａＬ・７０ａＲをガイド座７０ｂに固着した構造で、側面視で、ひげ根調製体６７と近接しひげ根切断刃６６に重接する状態で、根切駆動ケース４７中央部に上下調節可能に固定し、搬送してきた鱗茎と接当しひげ根切断装置７を上下することによりひげ根切断刃６６を適当な位置に上下すると共に、ひげ根を寄せながらひげ根切断刃６６に送り込むものである。
別の実施例の円盤式根切ガイド７１は、図８に示す通り、一端にメタル穴を有する一対の成型した板状の円盤取付体７１ｃＬ・７１ｃＲの他端をガイド座７１ｂに固着し、メタル穴に円盤体７１ａ・７１ａを内側より回転自在に嵌挿し抜け止めを施した構造である。
【００１８】
リンク取付体７３は、側面視で、前方延出面に上下２つのリンク取付のメタル穴を持ち、正面視下部Ｌ形面に取付穴を持つ一対の成型した板構造のリンク取付体７３Ｌ・７３Ｒで構成し、これを根切駆動ケース４７の上面左右端に締結固定し、このリンク取付帯７３Ｌ・７３Ｒとフレーム体５０の根切装置取付体５１とを４点リンクを構成するリンク７４・リンクピン７６により、ひげ根切断装置７を上下揺動可能に装着し動力伝達は、屈折伝動具７５を接続して行なうものである。
尚、ひげ根切断装置７揺動下限は、ストパー５１Ｌ・５１Ｒとリンク７４Ｌ・７４Ｒが接当し、鱗茎と根切ガイド７０との接当荷重はバランスバネ７７により適当な荷重に軽減している。
【００１９】
鱗茎搬出部８の構成は、側面視「Ｕ」字形溝形状のシュータ８０Ｌ・８０Ｒを正面視山形の傾斜位置に、後面に配置した切替えレバー８２に連動し搬出口４３から搬出した鱗茎をスムースにシュータ８０Ｌ・８０Ｒの溝に流す切替え板８１を山形の頂点付近に、更に、搬出鱗茎が上に飛び出さぬようガイドカバー８３をシュータ上部の一部に夫々配置し、調製機体４の搬出口４３を有する固定カバー５３ｃに沿って固着した構造で構成している。
なお、搬出鱗茎と混合した切断ひげ根が鱗茎収納場所に入らないようシュータ溝底部の１部に、下方に開放されたひげ根排出口８４Ｌ・８４Ｒを設け、排出されたひげ根等は地面に放出される。
【００２０】
鱗茎作物調製機の移動手段には、タイヤ、クローラによる自走式もあるが、一例である実施例の手押し式の車輪部の構成は、供給口４０側にはキャスター無し小径車輪３１Ｌ・３１Ｒを左右端に、エンジン１０側にはキャスター付車輪３２を中央に夫々をフレーム体５０の下面に締結固定した構成である。
なお、キャスター付車輪３２には、ブレーキレバー３３により機械の移動、固定を可能にする構造を織り込んでいる。

BACKGROUND OF THE INVENTION
The present invention provides bulb crops such as onions and garlic extracted from the cultivation field, supplied from the supply port of the preparation machine, removes the foliage and roots from the bulb portion, is prepared in a shipping form, and is delivered to the outlet. The present invention relates to a root cutting device for a preparation machine.
[0002]
[Prior art]
For example, in the case of a typical onion among bulb crops, the onion extracted in the cultivation field is placed on the straw and allowed to dry naturally for several hours before entering the preparation work, or an appropriate amount is bundled in the foliage and delivered to the drying field. In either case, the preparation work is either done manually using scissors, cutting the foliage and roots in two steps from the bulb, and separating them so as not to mix with the removed foliage and roots. It is common to harvest the bulb part, and it requires a labor to carry out from the field quickly and a lot of manual work, especially careful work to be careful when cutting the hair root.
It is known that this hair root cutting operation is performed by a preparation device mounted on a traveling vehicle. However, as a device capable of maintaining high accuracy of the hair root cutting position that significantly affects the quality of the harvested product, it is known.
