機体前端の作物搬送開始個所に位置された倒立姿勢の球状作物を搬送手段で処理主要部に取り込んでその茎葉部先側部分及び又はヒゲ根を切り離すように調製する球状作物調製機は知られている（例えば、特許文献１及び２など参照）。

【発明が解決しようとする課題】
上記した従来の球状作物調製機では作業者が畝上に堀り上げられている状態の球状作物を拾い上げては一つづつこれを正確な倒立姿勢として前記特定供給位置へ直接に供給することが必要であるが、該供給が意外と手間取るため、球状作物調製機が折角高い調製能力を有するものとなされていても、その調製能力を十分に発揮させることができないという問題がある。
本発明は斯かる問題点を解消させることのできる新規な球状作物調製機を提供することを目的とする。
【０００５】
【課題を解決するための手段】
上記目的を達成するため、本発明は次のようなものとなしてある。
即ち、請求項１記載の発明は、機体上の作物搬送開始個所に位置された倒立姿勢の球状作物を搬送手段で処理主要部に取り込んでその茎葉部先側部分及び又はヒゲ根を切り離すように調製する球状作物調製機において、球状作物を倒立姿勢で次々と供給されてその複数を倒立姿勢のまま同時に支持し且つこのように支持した各球状作物を重力作用により滑り移動させて順次に前記作物搬送開始個所へ移動させるものとした作物支持滑り供給手段を設けたものである。
【０００６】
この発明においては、作業者が地面に堀り上げられた球状作物の複数を拾い上げて前記作物支持滑り供給手段にそれらを倒立姿勢で供給し保持させる。該作物支持滑り供給手段は自身の支持した球状作物のそれぞれを重力作用により下方へ滑り移動させ最下位置の球状作物を前記作物搬送開始個所に位置させる。そして前記最下位置に位置された球状作物が前記搬送手段により搬送されるのであり、該搬送が行われると、この時点で前記作物支持滑り供給手段に支持されている球状作物のうちで最下位置となっている球状作物が先同様に重力作用により前記作物搬送開始個所まで滑り移動され、その後、先と同様に前記搬送手段により搬送される。このような作動が繰り返されて前記作物支持滑り供給手段に支持されている球状作物は動力や人手を要することなく順次に処理主要部へ搬送される。
【０００７】
また請求項２記載の発明は、機体上の作物搬送開始個所に位置された倒立姿勢の球状作物を搬送手段で処理主要部に取り込んでその茎葉部先側部分及び又はヒゲ根を切り離すように調製する球状作物調製機において、前記作物搬送開始個所へ向けて特定角度以上の傾斜で降下する特定長さ（球状部ｔ３の直径の数倍程度）以上の一対の平行な細幅状傾斜滑り面部を球状作物の球状部の径長よりも小さくてその茎葉部の径長よりも大きい距離となるように水平方向へ離間させたものとした作物支持滑り供給手段を装設したものである。
【０００８】
これによれば、一対の細幅状傾斜滑り面部はこれらの間にこれらの高い側の端部間から倒立姿勢の球状作物の首部を挿入されるのであり、このような球状作物の挿入が繰り返して行われると、複数の球状作物が一対の細幅状傾斜滑り面部間の空所である作物送り通路に一列となって倒立姿勢のまま支持され、一対の細幅状傾斜滑り面部上を重力作用により前記作物搬送開始個所へ向けて滑り移動する。この滑り移動により最下位置の球状作物が前記作物搬送開始個所に位置されてそれ以上の滑り移動を規制され、その後、前記搬送手段により前記処理主要部に取り込まれる。こうして一つの球状作物が取り込まれると、一対の細幅状傾斜滑り面部間に一列状に支持されている球状作物は再び重力作用により滑り移動して、このとき一対の細幅状傾斜滑り面部間に支持されている球状作物のうちの最下位置の球状作物が次に記作物搬送開始個所に位置されるのであり、以後、一対の細幅状傾斜滑り面部間に支持されている球状作物のそれぞれについてこれまでと同様の作動が繰り返される。
【０００９】
また請求項３記載の発明は、機体上の作物搬送開始個所に位置された倒立姿勢の球状作物を搬送手段で処理主要部に取り込んでその茎葉部先側部分及び又はヒゲ根を切り離すように調製する球状作物調製機において、前記作物搬送開始個所へ向かう特定長さ以上の一対の平行な細幅状傾斜滑り面部を球状作物の球状部の径長よりも小さくてその茎葉部の径長よりも大きい距離となるように水平方向へ離間させたものとした作物支持滑り供給手段を、前記作物搬送開始個所近傍の横向き軸回りの角度変更可能に装設したものである。
【００１０】
これによれば、請求項２記載の発明と同様の作用が得られるほかに次のような作用が得られるのであって、即ち、球状作物の性状に対応して、前記一対の平行な細幅状傾斜滑り面部の傾斜角度を変更調製することが可能となり、これにより前記一対の平行な細幅状傾斜滑り面部はこれの支持した各球状作物をその性状の如何に拘わらず、順次に、前記作物搬送開始個所まで重力作用により最適状態で滑り移動させるものとなる。
【００１１】
また請求項４記載の発明は、機体前端の作物搬送開始個所に位置された倒立姿勢の球状作物を搬送手段で処理主要部に取り込んでその茎葉部先側部分及び又はヒゲ根を切り離すように調製する球状作物調製機において、機体前側から前記作物搬送開始個所へ向かう特定長さ以上の左右一対の平行な前後向きの細幅状傾斜滑り面部を球状作物の球状部の径長よりも小さくてその首部の径長よりも大きい距離で左右方向へ離間させたものとした作物支持滑り供給手段を、前記作物搬送開始個所近傍の左右向き軸回りの角度変更可能に装設した構成となしている。
【００１２】
これによれば、請求項３記載の発明と同様の作用が得られるほかに次のような作用が得られるのであって、即ち、機体を前進移動させつつ、機体前方の地上に堀り上げられた球状作物を拾い上げて前記作物支持滑り供給手段に供給する手作業が効率的に行われるものとなり、また一対の前記細幅状傾斜滑り面部を左右向き軸回りへ大きく揺動させることにより、前記作物支持滑り供給手段の不使用状態での機体全長が短縮化されるものとなる。
【００１３】
また請求項５記載の発明は、機体本体部前端の左右向き軸１７、１７回りへの揺動可能な状態で機体本体部から前方へ張り出された前方張出部を備え、該前方張出部前端の作物搬送開始個所に位置された倒立姿勢の球状作物を搬送手段により前記前方張出部を経て前記機体本体部の処理主要部に取り込み、ここでその茎葉部先側部分及び又はヒゲ根を切り離すように調製する球状作物調製機において、機体前側から前記作物搬送開始個所へ向かう特定長さ以上の左右一対の平行な前後向きの細幅状傾斜滑り面部を球状作物の球状部の径長よりも小さくてその首部の径長よりも大きい距離で左右方向へ離間させたものとなされた作物支持滑り供給手段を、前記作物搬送開始個所近傍の左右向き軸回りの角度変更可能に装設した構成である。
【００１４】
これによれば、請求項４記載の発明と同様の作用が得られるほかに次のような作用が得られるのであって、即ち、前記作物支持滑り供給手段により前記作物搬送開始個所まで供給された球状作物は、その倒立姿勢が必ずしも安定状態とはなっていないのであるが、前記前方張出部を経て搬送される過程で、その倒立姿勢が安定化され、その後の調製処理が好適に行われるようになる。また前記前方張出部の傾斜角度を変更することにより、前記作物支持滑り供給手段への作物挿入位置の高さが一対の細幅状傾斜滑り面部の傾斜角度を変更することなく、即ち細幅状傾斜滑り面部上での球状作物の滑り移動の円滑性を損なうことなく、実際に作業する者にとっての最適大きさとなされるものとなる。
【００１５】
上記した請求項２、３又は４に記載した各発明は次のように具体化するのがよいのであって、即ち、請求項６に記載したように、前記作物搬送開始個所の位置した機体部分が高さ変更可能となされ、該機体部分上に作物支持滑り供給手段を装設した構成となす。
このようにすれば、請求項２、３又は４に記載した各発明について次のような作用が得られるのであって、即ち、一対の前記細幅状傾斜滑り面部がこれの傾斜角度を同一に維持したまま任意な高さに変更されるものとなり、前記作物支持滑り供給手段による前記作物搬送開始個所への球状作物の送給が適正且つ円滑に行われると共に、一対の前記細幅状傾斜滑り面部が作業者の身体に適合した高さとなされて労力少なく使用され得るものとなる。
【００１６】
【発明の実施の形態】
本発明の実施の形態について図面を参照して説明する。図１は玉葱用として構成された球状作物調製機の側面図、図２は調製装置の側面断面図、図３は球状作物調製機の正面図、図４は調製装置の前部を示す平面図、図５は調製装置における球状作物搬送手段の平面断面図、図６は調製装置の前部を拡大した側面図、図７は図６のイ部分の平面拡大図、図８は調製装置の後部の平面視概略図、図９は調製装置の後部に配設された排出シュ−タ−の背面図、図１０は調製装置の駆動系の側面図、図１１は同じく調製装置の駆動系の後面図、図１２はコンテナの掛止状態を示す球状作物調製機の側面図、図１３はコンテナの掛止された球状作物の一部省略後面図、図１４は球状作物調製機の調製処理可能状態を示す斜視図、図１５は球状作物調製機の前部の調製処理可能状態を示す斜視図、図１６は球状作物調製機の調製装置の不使用状態を示す斜視図、図１７は球状作物調製機の細長状結合板を示す側面図、図１８は球状作物調製機の前部の調製処理状態を示す作動説明図である。
【００１７】
図１及び図２に示すように、本発明に係る球状作物調製機は、走行装置Ａによって走行する自走車の車体Ｂに調製装置（機体本体部）Ｃを載装して自走形に構成される。そして、クロ−ラ型に構成した走行装置Ａを車体Ｂの後部に搭載した原動機１と連動連結された走行伝動装置２で駆動し、運転操作を車体Ｂから後延する操縦ハンドル３からなる運転部において行う歩行型の自走車となされており、その自走車の車体Ｂに載装した調製装置Ｃの各可動部を、前記原動機１に連動連結された作業部伝動装置４により駆動するように構成している。
【００１８】
自走車に載装する調製装置Ｃは、前部に配置される被処理物供給部Ｃ１と、後部に配置される処理装置部Ｃ２を主要素として構成され、被処理物供給部Ｃ１と処理装置部Ｃ２がそれぞれカバ−５によって覆われて、被処理物供給部Ｃ１の天板５ａの高さが処理装置部Ｃ２の天板５ｂの高さより低く形成され、被処理物供給部Ｃ１の天板５ａの左右方向中央部分に進行方向に平行する通路溝ｍ（図３及び図４参照）が開設されている。
【００１９】
そして、前記天板５ａより下方の被処理物供給部Ｃ１の室内に球状部支持搬送機構６と茎引きベルト機構７とからなる第１搬送装置８が配設され、この第１搬送装置８の搬送通路が被処理物供給部Ｃ１の天板５ａに開設されている前記通路溝ｍに対応位置され、また、第１搬送装置８の後部が処理装置部Ｃ２の室内に延出されて、その延出部分の上方に第２搬送装置９として左右一対の挟持ベルト機構からなる挟持搬送装置が設けられ、これらの第１搬送装置８と第２搬送装置９とで球状作物搬送手段Ｄが構成されて、第１搬送装置８により後送される球状作物（以下、玉葱という）を第２搬送装置９に受継ぎ挟持し、第２搬送装置９の後方位に組成される排出部に向けて搬送するようになっている。
【００２０】
また、第１搬送装置８の搬送中途部下方には、玉葱の茎葉の一定長さ以上の先端部分を予め荒切りするための第１切断装置Ｅが配設されるとともに、第２搬送装置９の搬送中途部上方に玉葱のヒゲ根を切断する第２切断装置Ｆが、また、第２搬送装置９の搬送中途部下方に荒切り後の残茎部を切断する第３切断装置Ｇが配設され、これらの第１〜第３切断装置によって搬送途上の玉葱から茎葉やヒゲ根を切除するようになっている。
【００２１】
図２及び図５に示すように、第１搬送装置８を構成する球状部支持搬送機構６は、左右の丸ベルト駆動プ−リ１０、１０と前方従動プ−リ１１、１１及び後方従動プ−リ１２、１２に左右の丸ベルト１４、１４をそれぞれ巻装して、左右の丸ベルト１４、１４の対面部間に玉葱の球状部を保持する搬送通路を形成するが、左右の丸ベルト駆動プ−リ１０、１０は、作業部伝動装置４中の左右の伝動ケ−ス１５、１５（図１参照）に立設される搬送駆動軸１６、１６に設けられ、また機体本体部Ｃの前側には被処理物供給部Ｃ１前端に配置された左右向きの回動支点軸１７、１７を中心にして上下揺動可能となされた前方張出部Ｃ３が設けられてあって、従動プ−リ１１、１１と後方従動プ−リ１２、１２は、回動支点軸１７、１７回りへ回動される前方張出部Ｃ３の一部をなす左右の前延フレ−ム１８、１８の前部と後部に配設されている。
【００２２】
したがって、前延フレ−ム１８、１８を回動支点軸１７、１７中心で上下方向に回動し、被処理物供給部Ｃ１の機枠との間に介装する支持ステ−１９を伸縮調節して任意の位置で固定することによって、被処理物供給部Ｃ１の前端部から前方に向けて延出する球状部支持搬送機構６の前方巻回部分６ａの上下傾斜姿勢を変更調節することができ、また、球状部支持搬送機構６の前方巻回部分６ａを仮想線ａで示しているように略直立状態に折曲して格納することができる。
【００２３】
なお、回動支点軸１７、１７の左右の軸端部には図６及び図７に示すようにガイドロ−ラ２０、２０が設けられ、これらのガイドロ−ラ２０、２０が、後方従動プ−リ１２、１２の後方位において丸ベルト１４、１４を下側から支えるようにされている。
【００２４】
また、前方従動プ−リ１１、１１を支承する支持軸の下方延長部分には前方Ｖプ−リ２２、２２が、後方従動プ−リ１２、１２を支承する支持軸の下方延長位置の後方位の支持軸２３ａには後方Ｖプ−リ２３、２３がそれぞれ取付けられ、前後のＶプ−リ２２、２２、２３、２３に、軟弾性材からなる左右一対の挟持ベルト２４、２４が巻回されて挟持搬送機構２５が構成され、上記球状部支持搬送機構６に球状部ｔ３が保持された玉葱の茎葉部ｔ１を、挟持搬送機構２５でもって挟持して後送するように構成されている。
【００２５】
さらに、挟持搬送機構２５の下側において前方従動プ−リ１１、１１を支持する回転軸には掻き込み用の左右一対のスタ−ホイル２６、２６が嵌着されると共に、挟持搬送機構２５の下側において後方従動プ−リ１２、１２を支持する回転軸には送り出し用のスタ−ホイル２７、２７が嵌着され、それぞれのスタ−ホイル２６、２６、２７、２７は弾性材からなる多数の突起を有している。また、左右の前延フレ−ム１８、１８の前後二個所の間は、正面視で上下逆のＵ字状を呈する連結体２８、２８によって、玉葱の移行に支障がないように連結されている。そして、後側の連結体２８の左右部位間にはコ形に屈曲されたベルト押さえ２８ａを左右向き軸２８ｂ回りの揺動変位可能に装着しており、該ベルト押さえ２８ａは左右向き軸２８ｂ回りの上下揺動限界位置で位置保持されるものとなされている。また球状部支持搬送機構６の前方巻回部分６ａは前方張出部Ｃ３と一緒にその不使用時に傾斜角度を増大させて図２中に仮想線ａで示すような格納状態となすことができるが、この際、ベルト押さえ２８ａは下側の限界位置に保持されて丸ベルト１４、１４をガイドロ−ラ２０、２０上に押さえるものとなり（図１６参照）、また球状部支持搬送機構６の使用時には図１などに示すように上側の限界位置に復帰されて玉葱の搬送に支障のない状態となる。
【００２６】
一方、図２及び図５に示すように、第１搬送装置８を構成する茎引きベルト機構７は、左右の伝動ケース１５、１５に立設される縦向き回転中心軸４８、４８に固定される左右の茎引き駆動プ−リ２９、２９と、この駆動プ−リ２９、２９から適宜前方において球状部支持搬送機構６の下側に配設される左右の茎引き従動プ−リ３０、３０とに挟持Ｖベルト３１、３１を巻回して構成されて、球状部支持搬送機構６に対する上下方向間隔が後方になるに従って拡がるように前高後低に配設されており、又、挟持Ｖベルト３１、３１の挟持作用部分はスポンジなどの軟弾性材で形成されて左右の挟持Ｖベルト３１、３１の対向面間に挟持する玉葱の茎葉部ｔ１を切損することがないように配慮されている。
【００２７】
また、左右の茎引き従動プ−リ３０、３０を嵌着した回転軸３２、３２は下方に延長され、その延長部分に左右一対のデイスク刃３３、３３が取付けられて前出の第１切断装置Ｅが構成されており、デイスク刃３３、３３は回転軸３２、３２に沿って上下方向に移動調節し、その調節によって玉葱の茎葉先端部分を予め切除する長さ（荒切り長さ）を適宜に変更できるようにされている。
【００２８】
また、茎引き従動プ−リ３０、３０及びデイスク刃３３、３３を嵌着する左右の回転軸３２、３２は、挟持搬送機構２５の後端部から少し後方に離間した部位に位置し、茎引きベルト機構７の前端部と挟持搬送機構２５の後端部との間の空間部に左右一対のスタ−ホイル３４、３４が配置されて、このスタ−ホイル３４、３４によって、挟持搬送機構２５の搬送後端から茎引きベルト機構７の搬送始端部に玉葱の茎葉部ｔ１を受け渡すようになされている。
【００２９】
前記左右のスタ−ホイル３４、３４は、球状部支持搬送機構６の左右の丸ベルト１４、１４によって回転駆動される垂下軸３５、３５に装着され、その装着部から放射方向に突出する弾性体の突起を有している。そして、各々のスタ−ホイル３４、３４の回転軌跡が前方側においては挟持搬送機構２５の終端側のスタ−ホイル２７、２７の回転軌跡内に一部入り込み、また後方側においては茎引きベルト機構７及び第１切断装置Ｅの間で両者７、Ｅの回転圏内に入り込んで回転するようになされている。
【００３０】
前記球状部支持搬送機構６の後部上方に配設される第２搬送手段９は、処理装置部Ｃ１の機枠に設けた左右の支持台（図示省略）の後部に位置する第２搬送駆動プ−リ３６、３６と、前部に位置する第２搬送従動プ−リ３７、３７と、両プ−リ３６、３７の間に配設されるアイドルプ−リ群とに左右の挟持ベルト３８、３８を巻回して両挟持ベルト３８、３８の対面部間に挟持搬送路を形成し、第２搬送駆動プ−リ３６、３６の支軸３９、３９を伝動機構４０、４０によって前出の搬送駆動軸１６、１６及び縦向き回転中心軸４８、４８に連動させて回転駆動するように構成されている。
【００３１】
なお、左右の挟持ベルト３８、３８の巻回外周部分はゴムや発泡性の合成樹脂などの弾性材で形成されていて、その巻回外周部分には断面形状が略「く」字状の抱持面が形設され、前述の挟持搬送路側で向い合う左右の抱持面の間に、第１搬送装置８によって後送されてくる玉葱の球状部ｔ３を受け継ぎ抱持して後方に搬送するようになっている。
【００３２】
しかして、前記搬送駆動軸１６、１６及び縦向き回転中心軸４８、４８は、図１０及び図１１にも示すように、左右の伝動ケ−ス１５、１５の内部に収容構成されるギヤ伝動機構４１、４１に連動連結され、各々のギヤ伝動機構４１、４１の入力軸４２、４２は、伝動ケ−ス１５、１５から下方にそれぞれ延出されて、処理装置部Ｃ１の室内下部に位置するケ−シング４３に横設された動力分配軸４４に自在継手４５及びベベルギヤ機構４６を介して連動連結され、また、動力分配軸４４は、ベルト伝動機構１３によって前記原動機１の出力軸４７に動力断続自在に連動連結されている。
【００３３】
したがって、原動機１を始動してベルト伝動機構１３を伝動状態に接続操作すると、原動機出力軸４７からの動力により左右の搬送駆動軸１６、１６及び縦向き回転中心軸４８、４８が所定の方向に各々回転駆動され、左右の搬送駆動軸１６、１６の回転によって球状部支持搬送機構６の左右の丸ベルト１４、１４、挟持搬送機構２５の左右の挟持ベルト２４、２４、スタ−ホイル２６、２６、スタ−ホイル２７、２７及び左右の引継用のスタ−ホイル３４、３４が駆動されて、それぞれが対面側において前方から後方に回転される。また、左右の縦向き回転中心軸４８、４８の回転によって茎引きベルト機構７の左右の挟持ベルト３１、３１及び、第１切断装置Ｅの左右のデイスク刃３３、３３が前方から後方に対向回転され、また左右の搬送駆動軸１６、１６及び、左右の縦向き回転中心軸４８、４８の回転によって第２搬送装置９の左右の挟持ベルト３８、３８が前方から後方に対向回転される。
【００３４】
このような作動状態のもとで、図６にみられるように、玉葱をその茎葉部ｔ１が下になりヒゲ根ｔ２が上になる倒立姿勢にして、球状部ｔ３を球状部支持搬送機構６の上側に位置させながら前方張出部Ｃ３における第１搬送装置８前端である作物搬送開始個所ｐ１に供給すると、球状部ｔ３と茎葉部ｔ１の境目部分（首部）が球状部支持搬送機構６に保持されるとともに、茎葉部ｔ１が挟持搬送機構２５によって挟持されて両搬送機構６、２５の協働によって玉葱全体が後方に搬送される。
【００３５】
そして、球状部支持搬送機構６で球状部ｔ３を保持しての搬送が続けられる一方で、挟持搬送機構２５の終端部に達した茎葉部ｔ１はスタ−ホイル２７、２７によってスタ−ホイル３４、３４の搬送作用圏内に送られスタ−ホイル３４、３４の搬送作用により茎引きベルト機構７の搬送始端部に引継ぎ挟持される。
【００３６】
また、スタ−ホイル３４、３４で茎葉部ｔ１が搬送されている間に、その茎葉部ｔ１の一定長さ以上の先端部分が第１切断装置Ｅのディスク刃３３、３３によって荒切りされるが、この際には、スタ−ホイル３４、３４が茎葉部ｔ１を第１切断装置Ｅの切断作用圏に強制的に押し込むように働くので、たとえ、茎葉部ｔ１が枯れていても確実に切断される。そして、切り離された茎葉部ｔ１は被処理物供給部Ｃ１から抜け落ちて圃場に放出される。この際、この切り離された茎葉部ｔ１を機体左右方向へ搬送して機外の特定位置に放出させることも差し支えない。
【００３７】
なお、上記の場合に、第１切断装置Ｅのディスク刃３３、３３は、玉葱の葉が分かれる部分よりも少し球状部ｔ３側に寄った部位を切断するように位置設定して設け、また、スタ−ホイル３４、３４は、ディスク刃３３、３３の上側又は下側に近接させて配置するのが好ましく、そうすることによって枯れた茎葉部ｔ１をも、より確実良好に荒切りできて以降の作業を円滑に行わせることができる。
【００３８】
茎葉部ｔ１の先端部分を荒切りされた玉葱は、球状部ｔ３が球状部支持搬送機構６によって保持されながら、荒切り後の茎葉残部ｔ１が茎引きベルト機構７に挟持されて更に後送が続けられ、その間、茎葉残部ｔ１が茎引きベルト機構７により引下げられることによって適正な倒立姿勢に矯正されながら移行されて、第２搬送装置９に至ると、左右の挟持ベルト３８、３８の相対向する抱持面の間に球状部ｔ３が抱持されて後送される。
【００３９】
そして、第２搬送装置９に球状部ｔ３が抱持されて搬送されている間に、第３切断装置Ｇによって茎葉残部ｔ１が球状部ｔ３との境目部分で切断され、また、球状部ｔ３の上方のヒゲ根ｔ２が第２切断装置Ｆによってその根元部から切断されるのである。
【００４０】
茎葉残部ｔ１を切断する第３切断装置Ｇは次のように構成されている。即ち、図２、図５、図１０及び図１１に示すように、左右の伝動ケ−ス１５、１５の後部に位置する入力軸４２、４２と一体か又は入力軸４２、４２に連動連結された左右の縦向き回転中心軸４８、４８が、左右一対の伝動ケ−ス１５、１５から上方に延設されて、第２搬送装置９の下側近傍に位置する軸上端部にディスクカッタ−４９、４９がそれぞれ嵌着され、左右一対のディスクカッタ−４９、４９は、両者の外周縁部が搬送中心線上で一部上下に重なるように配置され、その重なり合い部分が前方から後方に向けて対向回転して玉葱の茎葉残部ｔ１を切断するようになっている。
【００４１】
また、玉葱のヒゲ根ｔ２を切断する第２切断装置Ｆは、処理装置部Ｃ２の前端部上方に設けられている支持枠５０に支承する根起し機構５１と根切断機構５２とからなり、根起し機構５１が第２搬送装置９の上側近傍の搬送上手側に、そしてその搬送下手側に根切断機構５２が配置されている。
【００４２】
第２切断装置Ｆの根起し機構５１は、支持枠５０に軸受支持する前後方向の回転軸に設けられた左右一対のブラシ５３、５３を備え、両ブラシ５３、５３が対面側において下方から上方に回転して、球状部ｔ３上方のヒゲ根ｔ２を下から上方に梳き上げて起立整姿させるようになっている。
【００４３】
また、第２切断装置Ｆの根切断機構５２は、支持枠５０に上下動自在に連設した平行四節リンク５４の後延端に取着したヘッド枠５５と、そのヘッド枠５５に設けた駆動ケ−スから突出する左右の駆動軸に固設する左右一対のディスク刃５６、５６と、ディスク刃５６、５６の前部上側及び後部上側に配設するゲ−ジ輪５７、５７とで構成されている。
【００４４】
そして、前記平行四節リンク５４と支持枠５０との間に上方への付勢バネ（図示省略）が介装され、前記ゲ−ジ輪５７、５７が球状部ｔ３の上部に当接した際にその当接荷重でヘッド枠５５を軽く円滑に上方に退動させて球状部ｔ３に対するディスク刃５６、５６の上下位置を自動的に調節しながら前記根起し機構５１が起立整姿したヒゲ根ｔ２を根元部から切断するようになっている。
【００４５】
なお、根起し機構５１における左右一対のブラシ５３、５３は、前出のケ−シング４３から前方に延設される水平回転軸５８に連動するベルト伝動機構５９によって各々所期の方向に回転駆動され、また、根切断機構５２の左右一対のディスク刃５６、５６は、前記ベルト伝動機構５９からドライブ軸６０を介してヘッド枠５５の駆動ケ−スに伝達される動力でもってそれぞれ所期の方向に回転駆動されるようになっている。
【００４６】
しかして、第３切断装置Ｇのディスクカッタ−４９、４９、伝動ケース１５、１５、ケーシング４３及び動力分配軸４４の後側でディスクカッタ−４９、４９及び伝動ケース１５、１５の下方には、ディスクカッタ−４９、４９によって切断された茎葉残部ｔ１と、第２切断装置Ｆにおける根切断機構５２の両ディスク刃５６、５６によって切断されたヒゲ根ｔ２のうちの一部を機外の特定位置に搬出するための排出コンベア６１が設けてある。図８に示すように、このコンベア６１は、ベルト伝動機構１３の中間プーリ１３ａからベベルギヤ機構１３ｂを介して連動される前向きの水平回転軸５８に嵌着したコンベア駆動プ−リ６２と、水平回転軸５８に平行する回転軸に取付けたコンベア従動プ−リ６３とにコンベアベルト６４を巻回して構成されている。
【００４７】
この際、前記コンベアベルト６４の外周には、同ベルト６４の回動方向とは交差する方向の複数の搬送突起６５を設けて、コンベアベルト６４上に落下する茎葉残部ｔ１などの落下物を搬送突起６５で係引して、排出コンベア６１の終端部から確実に運び出すようにするのが好ましく、また、コンベアベルト６４の前後両脇部と搬送始端側の脇部には、前側ガイド板６６、後側ガイド板６７、始端側ガイド板６８をそれぞれ仕切状に立設して、これらのガイド板により、切断された茎葉残部ｔ１などがコンベアベルト６４上に確実に落下するように誘導すると共にコンベアベルト６４上から逸脱しないようにするのが好ましい。
【００４８】
ディスクカッター４９、４９や排出コンベア６１周辺の構成について図２、図８、図１０及び図１１を参照してさらに詳細に説明すると、左右一対の伝動ケ−ス１５、１５は、平面視で排出コンベア６１の後方位から前方左右外向きに拡がって逆ハ字状を呈するように配設されている。
【００４９】
左右の伝動ケース１５、１５の相互間や左右の縦向き回転中心軸４８、４８の相互間にはディスクカッター４９、４９で切断されて落下する茎葉残部ｔ１が後方へ通過するための通路として使用される通路用空間ｎが設けられている。左右のディスクカッタ−４９、４９は両伝動ケ−ス１５、１５の後端部に配置され、両ディスクカッタ−４９、４９の重合部分の前部、すなわち切断作用位置が、両伝動ケ−ス１５、１５間の逆ハ字状空間の後部に位置され、また第２搬送手段９に対しては、両挟持ベルト３８、３８が形成する挟持搬送路の終端寄り部分に対応するように位置されている。
【００５０】
左右の伝動ケース１５、１５の下方にはケーシング４３や動力分配軸４４を覆うための略水平横向きのカバー部材１００が緩やかな後上がり状に設けてあり、またこのカバー部材１００の上側には前記通路用空間ｎに面した各伝動ケース１５部分を覆う左右一対のカバー部材１０１、１０１が設けてあり、これらカバー部材１０１、１０１はカバー部材１００の上面に前後向き起立状に固着されると共に前側部分を前方へ向かうに伴って相互間寸法が漸次大きくなるような平面視漏斗状に形成されている。
【００５１】
また、排出コンベア６１の前側脇に位置する前側ガイド板６６は、前記カバー部材１００の後部を下向き垂直状に屈曲して形成されコンベアベルト６４の前側に隣接して位置されており、また排出コンベア６１の後側脇に位置する後側ガイド板６７は、コンベアベルト６４の後側に隣接して立設され、側面視（図２参照）において伝動ケース１５、１５とほぼ同程度の高さとなしている。
【００５２】
上記したディスクカッター４９、４９や排出コンベア６１周辺での処理状況について説明すると、第２搬送装置９や茎引きベルト機構７によりディスクカッタ−４９、４９の切断作用位置に送られる玉葱の茎葉残部ｔ１はこれが多少嵩張っていても左右のカバー部材１０１、１０１の平面視漏斗状の前側部分に案内されてそれらカバー部材１０１、１０１の後部相互間に円滑に移動するものとなる。
【００５３】
そしてディスクカッタ−４９、４９で切断された茎葉残部ｔ１は、球状部ｔ３から分離される直前のディスクカッタ−４９、４９の回転力を受けて後方へ跳ね飛ばされる傾向となり、このように跳ね飛ばされた後は左右の縦向き回転中心軸４８、４８の相互間や、左右のカバー部材１０１、１０１の相互間を経て重力作用により落下しつつ円滑に後方へ移動し、この後は直接に或いは、後側ガイド板６７に衝突するなどして円滑にコンベアベルト６４上に落下するものとなり、次はコンベアベルト６４で機体横方へ搬送され、この搬送中には前側ガイド板６６と後側ガイド板６７によりコンベアベルト６４の前後側に脱落するのを阻止され、最終的に機体の特定位置から圃場へ的確に排出される。
【００５４】
一方、ディスク刃５６、５６で切断されたヒゲ根ｔ２は球状部ｔ３から分離される直前のディスク刃５６、５６の回転力を受けて後方へ跳ね飛ばされる傾向となり、このように跳ね飛ばされた後はその多くが伝動ケース１５、１５の存在箇所を経てコンベアベルト６４上に落下するものとなり、その他のものは略水平横向きのカバー部材１００の上面に落下したり、直接に圃場に落下するものとなる。
【００５５】
またカバー部材１００の上面にはヒゲ根ｔ２のほか茎葉部ｔ１の千切れ片や、玉葱に付着した土砂なども落下するのであり、これら落下物はカバー部材１００が前下がり状に傾斜しているため機体振動により前方へ案内移動され動力分配軸４４などの回転部に当たらないように落下される。
【００５６】
ディスクカッター４９、４９や排出コンベア６１周辺での処理状況は以上のとおりであり、こうして第２切断装置Ｆによりヒゲ根ｔ２が切断され第３切断装置Ｇにより茎葉残部ｔ１が切断された玉葱の球状部ｔ３は、第２搬送手段９の終端部で挟持を解かれるが、その部分の下方位には定められた角度で後低姿勢に傾斜する受樋６９が設けられて、該受樋６９の後端が、その後方位に隣接して配置されているシュ−タ−７０の受口７０ａに対応位置され、第２搬送装置９の終端部で挟持を解かれた玉葱の球状部ｔ３とそれに付随して持ち運ばれる切断後のヒゲ根ｔ２は、受樋６９の前部に落下し、後低に傾斜する受樋６９に沿って移行して前記受口７０ａからシュ−タ−７０内に投入され、受口７０ａの下方位から図９に示す左右の排出筒７０Ｌ、７０Ｒのいずれかに案内されてその外方端の送出口１０２から機外に送出されるようになっている。
【００５７】
図９にみられるように、シュ−タ−７０は、左右方向の中央部位に位置する縦筒７０Ａの下端部から左右に排出筒７０Ｌ、７０Ｒを分岐させて形成され、左右排出筒７０Ｌ、７０Ｒの分岐部下底壁７０ｂの上面側に前後方向の回動支点軸７５を中心にして左右揺動可能に枢支した排路切換板７６が設けられている。
【００５８】
そして、排路切換板７６は、シュ−タ−７０の外部において前記回動支点軸７５に連係される切換操作手段（図示省略）を操作することによって、左側の排出筒７０Ｌを閉塞し右側の排出筒７０Ｒを縦筒７０Ａに連通させる左倒れ位置（図９の実線図示位置）と、右側の排出筒７０Ｒを閉塞し左側の排出筒７０Ｌを縦筒７０Ａに連通させる右倒れ位置（図９の仮想線図示位置）とに択一的に切換維持できるようになされている。
【００５９】
さらに、回動支点軸７５への取付基部から適宜先端側に寄った排路切換板７６の中途部には、同切換板７６に対して自由回動できるように取付けられた補助板７７Ｌ、７７Ｒが設けられ、これらの補助板７７Ｌ、７７Ｒが、排路切換板７６の回動支点軸７５への取付基部を含む分岐部下底壁７０ｂの上側を山形状に覆って、排路切換板７６が左倒れ位置にある場合には、右側の補助板７７Ｒが排路切換板７６の傾斜角度より緩い傾斜角度で右側の排出筒７０Ｒの下底部内面に連なり、また逆に、排路切換板７６が右倒れ位置にある場合には、左側の補助板７７Ｒが排路切換板７６の傾斜角度より緩い傾斜角度で左側の排出筒７０Ｒの下底部内面に連なるようにしてある。なお、受樋６９からの玉葱の球状部ｔ３を受け入れる受口７０ａは、縦筒７０Ａの前面側に開設されている。
シュ−タ−の左右の排出筒７０Ｌ、７０Ｒの送出口１０２から機外に送出された球状部ｔ３は例えば図１２及び図１３に示すように機体側部に掛け止められた上面開放型のコンテナＣＴに収容させるのである。
【００６０】
なお、シュ−タ−７０の左右の排出筒７０Ｌ、７０Ｒの外端部に必要に応じて、樋状の延長排出樋７８、７８を折り畳み収納可能に装着し得る構造となすことも差し支えない。この延長排出樋７８、７８はコンテナＣＴを使用しない場合において球状部ｔ３を圃場の地面上に直接に放出させるときに使用する。
【００６１】
次に本発明に係る特徴部分について説明する。
図４、図１４、図１５及び図１６に示すように、前方張出部Ｃ３の前側から作物搬送開始個所ｐ１へ向かう作物支持滑り供給手段Ｃ４が形成されており、具体的には次のようになされている。
即ち、前方張出部Ｃ３前端から前方へ向けて案内体１０３が延出させてあり、この案内体１０３は左右一対の案内要部１０３ａ、１０３ａを有している。そして、これら一対の案内要部１０３ａ、１０３ａは作物搬送開始個所ｐ１の左右各側の前方張出部Ｃ３前端個所から延出させてあり、前方張出部Ｃ３前端個所と左右の各案内要部１０３ａ、１０３ａとは左右向き軸ｄ（図４参照）回りへ折れ曲がり自在となされたヒンジで結合させている。左右の案内要部１０３ａ、１０３ａは対称構造となされており、各案内要部１０３ａは前後方向へ長い左右向き面１０４ａと垂直面１０４ｂを具備すると共に、図４に示すように左右向き面１０４ａの内側前後向き側縁ｇを前後向きの管部材で形成され、該管部材の周面の上部を細幅状傾斜滑り面部ｈとなされている。そして、一対の細幅状傾斜滑り面部ｈ、ｈは平行配置されていて前後方向長さが球状部ｔ３の直径の数倍程度、具体的には例えば３０ｃｍ以上（好ましくは凡そ５０ｃｍ程度）となされ、且つ、玉葱の球状部ｔ３の径長よりも小さくてその首部の径長よりも大きい距離（例えば凡そ４０〜５０ｍｍ程度）だけ左右方向へ離間されている。この際、一対の細幅状傾斜滑り面部ｈ、ｈの間に形成された前後方向へ長い空所１０５は作物送り通路として機能する。
【００６２】
左右の案内要部１０３ａ、１０３ａの長さ方向途中個所は門形部材１０６で結合して左右の案内要部１０３ａ、１０３ａを一体状となしている。門形部材１０６は玉葱がこれの内方を通過できる形態となされており、その頂面１０６ａの前部には細幅状傾斜滑り面部ｈの傾斜角度よりも大きな傾斜角度で前方へ張り出された延長部１０６ｂが形成され、左右の細幅状傾斜滑り面部ｈ、ｈ上面を滑り移動する玉葱のヒゲ根ｔ２などが頂面１０６ａに絡まないようになされている。また左右の細幅状傾斜滑り面部ｈ、ｈの前端縁には屈曲された棒部材１０７、１０７を張り出し状に且つ左右向き面１０４ａ、１０４ａと同一平面上に合致させて固着し、これら棒部材１０７、１０７の案内辺部ｉ、ｉ（図４参照）をこれらの左右方向距離が前方へ向けて漸次拡大するように位置させ、作物送り通路１０５の前側からこれの内方への茎葉部ｔ１の挿入を行い易くなしている。
【００６３】
また左右の案内要部１０３ａ、１０３ａの垂直面部１０４ｂ、１０４ｂの長さ途中個所に把手部付ボルト１０８、１０８を螺着すると共に、前方張出部Ｃ３の上面の左右各側の長さ途中の二個所にも別の把手部付ボルト１０９、１０９が螺着される個所として前側の突起部１１０、１１０と後側の突起部１１１、１１１を形成し、左右各側において把手部付ボルト１０９の螺着個所と任意な一つの突起部１１０又は１１１とが把手部付ボルト１０８、把手部付ボルト１０９及び細長状結合板１１２で結合される構成としている。この際、把手部付ボルト１０８の螺着個所と前側の突起部１１０とを細長状結合板１１２で結合させると、案内体１０３は図１４及び図１５に示すように前方へ張り出し状となって使用可能姿勢となり、また把手部付ボルト１０９と後側の突起部１１１とを細長状結合板１１２で結合させると、案内体１０３は図１６に示すように折れ曲がり状となって格納姿勢となる。
【００６４】
各細長状結合板１１２の前端部には図１７に示すようにこれの長手方向へ長くなされた透孔１１２ａが形成されており、該透孔１１２ａはこれの長手方向途中に形成された複数の掛け止め用切欠部ｊを有しており、該複数の掛止用切欠部ｊの任意な一つに把手部付ボルト１０８のボルト部が挿通状に掛け止められるのであり、また各細長状結合板１１２の後端部には把手部付ボルト１０９の挿通される円孔１１２ｂが形成されており、該円孔１１２ｂに挿通された把手部付ボルト１０９が左右各側の前後の突起部１１０、１１１の何れかのものに螺着されるのである。この際、把手部付ボルト１０９の掛け止められる掛止用切欠部ｊを他の位置の掛止用切欠部ｊに変更することにより、案内体１０３の傾斜角度が微調整される。
【００６５】
次に圃場の畦上に堀り上げられて適宜時間、天日乾燥された状態の玉葱を調製する場合の上記特徴部分の使用例や各部の作動について説明する。
案内体１０３が図１６に示すような格納姿勢となされた状態の機体を畦の一端に走行移動させてその畦の他端へ向けて前進できる姿勢となすと共に、エンジン１から走行装置Ａへの動力伝達を遮断してエンジンの作動状態下で一時的に機体の走行を停止させる。この後、支持ステ−１９を短縮させて前方張出部Ｃ３を少し前下がり姿勢の状態として固定すると共に、把手部付ボルト１０９を後側の突起部１１１から外して案内体１０３を左右向き軸ｄ、ｄ（図４参照）回りの前方へ揺動させ、この後、この把手部付ボルト１０９を前側の突起部１１０に螺着して、細長状結合板１１２の後端を前側の突起部１１０に固定させるのであり、これにより案内体１０３は図１４及び図１５に示すような使用可能状態となる。
【００６６】
次に作業者は畦上の玉葱の一つづつを拾い上げて左右の細幅状傾斜滑り面部ｈ、ｈの先端部間個所へ、或いは畦上の玉葱の複数を拾い上げてその一つづつを左右の細幅状傾斜滑り面部ｈ、ｈの先端部間個所へ順次に挿入する。この挿入は玉葱の球状部ｔ３を手で持って先ず倒立姿勢とし、次にその首部を左右の細幅状傾斜滑り面部ｈ、ｈの先端間個所へ前方から押し入れるように行うのであり、このように挿入された玉葱は首部近傍の球状部ｔ３を左右の細幅状傾斜滑り面部ｈ、ｈに支持されて重力作用により倒立姿勢を保持しつつ左右の細幅状傾斜滑り面部ｈ、ｈ上を前下方へ速やかに滑り移動する。
【００６７】
このような玉葱の挿入処理において、作物送り通路１０５内に玉葱の位置するスペースが存在する限り、次に挿入されるべき玉葱は球状部支持搬送機構６や茎引きベルト機構７の搬送能力とは無関係に待ち時間なく挿入できるのである。したがって、作物送り通路１０５が図１８に示すように例えば４つの玉葱を同時に支持し得る長さであれば、作物送り通路１０５上に４つの玉葱が同時に支持された状態となるまでは待ち時間なく連続的に玉葱を挿入できるのである。
【００６８】
このように挿入された玉葱のうち、作物送り通路１０５上の最下位置に位置したものは重力作用により動力や人為力を要することなく作物搬送開始個所ｐ１に到達するのであり、ここに到達した玉葱は球状部支持搬送機構６などの搬送手段により前方張出部Ｃ３の搬送経路を経て処理主要部をなす調製装置Ｃに搬送されてここで既述したようにその調製処理が実施される。
【００６９】
案内体１０３を経て作物搬送開始個所ｐ１に到達した玉葱はその滑り移動による影響などにより必ずしも適正な倒立姿勢となっていないのであるが、前方張出部Ｃ３における球状部支持搬送機構６などの搬送手段により搬送される各玉葱は隣接した玉葱との間隔を大きくなされて玉葱同士の干渉を受け難くなった状態で支持され搬送されるため、前方張出部Ｃ３での搬送過程で、その倒立姿勢を適正且つ画一的となされて、処理装置部Ｃ２にてヒゲ根ｔ２や茎葉部ｔ１を適正に切除されるものとなる。
【００７０】
左右の細幅状傾斜滑り面部ｈ、ｈ上での玉葱の滑り移動の速度は左右の細幅状傾斜滑り面部ｈ、ｈの傾斜角度や玉葱の性状などによって大小に変化するが、それが大き過ぎると、玉葱同士の接触や、玉葱と、案内体１０３や前方張出部Ｃ３との接触により玉葱が損傷することが生じる。したがって、作業者は現場の状況を見ながら、その滑り移動速度が大き過ぎるときは案内体１０３の傾斜角度を小さくして左右の細幅状傾斜滑り面部ｈ、ｈのそれを小さくなす。一方、左右の細幅状傾斜滑り面部ｈ、ｈ上での玉葱の滑り移動が停止したり或いはその滑り移動の速度が停止しないものの小さすぎるときは、玉葱の供給が能率的に行えないのであり、このようなときは案内体１０３の傾斜角度を逆に大きくして左右の細幅状傾斜滑り面部ｈ、ｈのそれを大きくなす。
【００７１】
左右の細幅状傾斜滑り面部ｈ、ｈの先端高さは作物送り通路１０５へ玉葱を挿入する作業を楽に行う上で重要であり、この高さは実際に作業する者の体格に関連した最適大きさとなすことが必要である。しかし、前述のように案内体１０３の傾斜角度を変化させると、左右の細幅状傾斜滑り面部ｈ、ｈの先端高さも変化するため、細幅状傾斜滑り面部ｈ、ｈの傾斜角度と、細幅状傾斜滑り面部ｈ、ｈの先端高さとの何れも最適大きさとなすには、作物搬送開始個所ｐ１の高さを大小に変化させることが必要となり、単に左右の細幅状傾斜滑り面部ｈ、ｈの傾斜角度のみを変更するような調整では足りないのでる。この場合は、支持ステー１９を伸縮操作して前方張出部Ｃ３の傾斜角度を調整すると共に前方張出部Ｃ３に対する案内体１０３の傾斜角度を変化させるようにする。
機体の前側近傍の畦上に存在した玉葱を全て拾い上げて作物送り通路内へ供給した後は、機体の側部に設けられた走行伝動系のクラッチレバーＲを一時的に入り操作して機体を適当距離だけ前進させて再び停止させ、ここで先と同様に、機体の前側近傍に存在した玉葱を拾い上げて作物送り通路１０５内へ供給するようになすのであり、以後、同様な処理が繰り返される。
【００７２】
上記実施例は次のように変形することができる。
即ち、スターホイル２６、２７、３４は必要に応じて設ければよいもので省略することも差し支えない。
特に、スターホイル３４を省略したときは、第１切断装置Ｅは回動支点軸２０にできるだけ近接させるのがよいのであり、これにより機体全長が短縮化される。
また調整処理する玉葱が茎葉部長さの短い種類のものであれば、第１切断装置Ｅは省略しても差し支えない。
【００７３】
【発明の効果】
上記した本発明によれば、次のような効果が得られる。
即ち、請求項１記載のものによれば、調製処理すべき球状作物を供給する際に、球状部支持搬送機構６や茎引きベルト機構７の搬送能力とは無関係に、作物支持滑り供給手段Ｃ４に同時に保持され得る数量までは極めて迅速に作物支持滑り供給手段Ｃ４内に供給することができ、このように供給された球状作物を動力や人為力を要することなく重力作用により作物搬送開始個所ｐ１に順次に位置させて処理装置部Ｃ２に取り込ませることができるのであり、要するに、球状作物の供給を簡易なバッチ処理方式により迅速且つ経済的に行うこと可能となすものである。この結果、処理装置部Ｃ２の調製処理能力を十分に発揮させて能率的な調製処理が行えるようになる。また作業者は球状作物を調製装置Ｃに供給する際、作物搬送開始個所ｐ１に位置された球状作物が球状部支持搬送機構６によって取り込まれるまで、畦上面から拾い上げた球状作物を持ったまま待機する必要がなくなるため、作業者の疲労が軽減されるものとなる。
【００７４】
請求項２記載のものによれば、請求項１記載の発明と同様な効果が得られる上に次のような効果が得られるのであって、即ち、一対の平行な細幅状傾斜滑り面部ｈ、ｈにより作物支持滑り供給手段Ｃ４を簡易且つ安価に製作することのできるものとなる。
【００７５】
請求項３記載のものによれば、請求項２記載の発明と同様な効果が得られる上に次のような効果が得られるのであって、即ち、球状作物の性状に対応して、前記一対の平行な細幅状傾斜滑り面部ｈ、ｈの傾斜角度を変更調製することが可能となり、したがって前記一対の平行な細幅状傾斜滑り面部ｈ、ｈで支持されている各球状作物をその性状の如何に拘わらず、作物搬送開始個所ｐ１まで重力作用により順次に最適状態で滑り移動させることができるのである。
【００７６】
請求項４記載のものによれば、請求項３記載の発明と同様な効果が得られる上に次のような効果が得られるのであって、即ち、機体を前進移動させつつ、機体前方の地上に堀上げられた球状作物を拾い上げて作物支持滑り供給手段Ｃ４に供給する手作業を効率的に行うことができ、また一対の細幅状傾斜滑り面部ｈ、ｈを左右向き軸ｄ、ｄ回りへ大きく揺動させることにより、作物支持滑り供給手段Ｃ４の不使用状態での機体全長を短縮化させることができるのである。
【００７７】
請求項５記載のものによれば、請求項４記載の発明と同様な効果が得られる上に次のような効果が得られるのであって、即ち、作物支持滑り供給手段Ｃ４により作物搬送開始個所ｐ１まで供給された球状作物は、その倒立姿勢が必ずしも安定状態とはなっていないのであるが、前方張出部Ｃ３を経て搬送される過程で、その倒立姿勢を安定化させることができ、その後の調製処理を好適に行わせることができるようになる。また機体本体部Ｃ前端の左右向き軸２０回りの揺動可能となされた前方張出部Ｃ３の傾斜角度を変更することにより、作物支持滑り供給手段Ｃ４への作物挿入位置の高さを一対の細幅状傾斜滑り面部ｈ、ｈの傾斜角度を変更することなく、即ち細幅状傾斜滑り面部ｈ、ｈ上での球状作物の滑り移動の円滑性を損なうことなく、現場の作業者に対する最適大きさとなすことができるものである。
【００７８】
請求項６に記載したものによれば、請求項２、３又は４に記載の発明について、請求項５に記載の発明と同様な効果が得られるのである。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a spherical crop preparation machine which cuts off the foliage tip and / or mustache root of a spherical crop such as onion.
[0002]
[Prior art]
There is a known spherical crop preparation machine that takes a spherical crop in an inverted posture located at a crop transport start point at the front end of the fuselage and takes it into a processing main part by a transporting means and prepares so as to cut off a foliage tip side part and / or a mustache root. (For example, see Patent Documents 1 and 2).

[0004]
[Problems to be solved by the invention]
In the above-mentioned conventional spherical crop preparation machine, the worker picks up the spherical crops in a state of being dug up on the ridge, and supplies them directly to the specific supply position as an accurate inverted posture one by one. Although it is necessary, since the supply is unexpectedly troublesome, there is a problem that even if the spherical crop preparation machine has a high preparation ability, the preparation ability cannot be sufficiently exerted.
An object of the present invention is to provide a novel spherical crop preparation machine that can solve such a problem.
[0005]
[Means for Solving the Problems]
To achieve the above object, the present invention is as follows.
That is, the invention according to claim 1 is configured such that a spherical crop in an inverted posture located at a crop transport start point on an airframe is taken into a processing main part by a transport means, and a foliage tip side part and / or a mustache root thereof are cut off. In the spherical crop preparation machine to be prepared, the spherical crops are supplied one after another in an inverted posture, a plurality of the spherical crops are simultaneously supported in the inverted posture, and each of the spherical crops thus supported is slid and moved by gravity to sequentially produce the crops. It is provided with a crop support slide supply means which is to be moved to a transfer start point.
[0006]
In the present invention, an operator picks up a plurality of spherical crops dug up on the ground, and supplies and holds the crop support slide supplying means in an inverted posture. The crop-supporting-sliding supply means slides each of the spherical crops supported by the cropping apparatus downward by gravity, and positions the lowest spherical crop at the crop transfer start point. Then, the spherical crop located at the lowermost position is transported by the transporting means. When the transport is performed, at this time, the lowest one of the spherical crops supported by the crop supporting slide supply means is obtained. The spherical crop at the position is slid to the crop transport start point by the action of gravity as before, and then transported by the transport means as before. By repeating such an operation, the spherical crops supported by the crop support sliding supply means are sequentially conveyed to the main processing section without requiring power or manual operation.

A pair of left and right cover members 101, 101 are provided for covering the respective transmission cases 15 facing the passage space n. These cover members 101, 101 are fixed to the upper surface of the cover member 100 in a front-rear direction and in a front-rear direction. The portion is formed in a funnel shape in plan view such that the mutual dimension gradually increases as going forward.
[0051]
A front guide plate 66 located on the front side of the discharge conveyor 61 is formed by bending the rear part of the cover member 100 downward and vertically, and is positioned adjacent to the front side of the conveyor belt 64. The rear guide plate 67 located on the rear side of the rear side of the conveyor belt 64 is erected adjacent to the rear side of the conveyor belt 64 and has substantially the same height as the transmission cases 15 in a side view (see FIG. 2). ing.
[0052]
The processing situation around the disk cutters 49, 49 and the discharge conveyor 61 will be described. The on-leaf remaining portion t1 of the onion sent to the cutting action position of the disk cutters 49, 49 by the second transport device 9 and the pulling belt mechanism 7 is described. Even if it is somewhat bulky, it is guided by the funnel-shaped front portions of the left and right cover members 101, 101 and smoothly moves between the rear portions of the cover members 101, 101.
[0053]
The foliage residue t1 cut by the disk cutters 49, 49 tends to be bounced backward by receiving the rotational force of the disk cutters 49, 49 immediately before being separated from the spherical portion t3. After that, it moves smoothly between the left and right vertical rotation center axes 48 and 48 and between the right and left cover members 101 and 101 while falling by gravity, and thereafter directly or afterwards. Then, the belt is smoothly dropped on the conveyor belt 64 by colliding with the rear guide plate 67, and then is conveyed laterally by the conveyor belt 64. During this conveyance, the front guide plate 66 and the rear guide The plate 67 prevents the conveyor belt 64 from dropping to the front and rear sides and is finally discharged from a specific position of the machine to a field.
[0054]
On the other hand, the beard root t2 cut by the disk blades 56, 56 tends to be bounced backward by receiving the rotational force of the disk blades 56, 56 immediately before being separated from the spherical portion t3, and is thus bounced off. After that, many of them fall on the conveyor belt 64 via the transmission cases 15, 15, and others fall on the upper surface of the cover member 100 which is substantially horizontally oriented horizontally, or fall directly on the field. It becomes.
[0055]
On the upper surface of the cover member 100, besides the mustache root t2, a fragment of the foliage t1 and the earth and sand attached to the onion also fall, and the fallen object is such that the cover member 100 is inclined forward and downward. Therefore, the vehicle is guided forward by the body vibration and falls so as not to hit a rotating part such as the power distribution shaft 44.
[0056]
The processing status around the disk cutters 49, 49 and the discharge conveyor 61 is as described above. Thus, the spherical shape of the onion in which the beard root t2 is cut by the second cutting device F and the foliage residue t1 is cut by the third cutting device G The portion t3 is released from being pinched at the terminal end of the second transport means 9, and a receiving gutter 69 is provided in the lower direction of the portion, which is inclined at a predetermined angle to the rear lower position. The rear end is positioned corresponding to the receiving port 70a of the shooter 70 which is disposed adjacent to the direction thereafter, and the spherical part t3 of the onion, which is released at the end of the second transporting device 9, and the accompanying part. The cut beard root t2 which is carried and dropped into the front of the trough 69, moves along the trough 69 which inclines rearward, and is thrown into the shutter 70 from the above-mentioned receptacle 70a. The left and right discharge cylinders 7 shown in FIG. L, is adapted to be delivered to the outside from the outlet 102 of the outer end is guided to one of the 70R.
[0057]
As can be seen in FIG. 9, the shutter 70 is formed by branching left and right discharge cylinders 70L and 70R from the lower end of a vertical cylinder 70A located at the center in the left and right direction, and forming left and right discharge cylinders 70L and 70R. A discharge path switching plate 76 is provided on the upper surface side of the lower bottom wall 70b of the branch portion so as to be swingable left and right about a pivot shaft 75 in the front-rear direction.

A left tilt position (a position shown by a solid line in FIG. 9) that connects the discharge cylinder 70R to the vertical cylinder 70A, and a right tilt position (a position illustrated in FIG. 9) that closes the right discharge cylinder 70R and connects the left discharge cylinder 70L to the vertical cylinder 70A. (Indicated by a virtual line).
[0059]
Further, auxiliary plates 77L and 77R attached so as to be freely rotatable with respect to the switching plate 76 are provided in a middle portion of the discharge path switching plate 76 which is appropriately shifted to the distal end side from the mounting base to the rotation fulcrum shaft 75.

The receiving port 70a for receiving the spherical portion t3 of onion from the receiving gutter 69 is opened on the front side of the vertical tube 70A.
The spherical portion t3 sent out of the machine from the outlets 102 of the left and right discharge cylinders 70L and 70R is, for example, an open-top container hung on the side of the machine as shown in FIGS. It is stored in CT.
[0060]
It should be noted that the gutter-shaped extended discharge gutters 78, 78 may be folded and stowably mounted on the outer ends of the left and right discharge cylinders 70L, 70R of the shutter 70 as necessary. The extended discharge gutters 78 are used when the container CT is not used to discharge the spherical portion t3 directly onto the field ground.
[0061]
Next, the characteristic portions according to the present invention will be described.
As shown in FIG. 4, FIG. 14, FIG. 15 and FIG. 16, a crop support sliding supply means C4 is formed from the front side of the front overhang portion C3 to the crop transport start point p1. It has been made.
That is, the guide body 103 is extended forward from the front end of the front extension C3, and the guide body 103 has a pair of left and right guide main parts 103a, 103a. The pair of guide portions 103a, 103a extend from the front end portions of the front overhang portion C3 on the left and right sides of the crop transport start point p1, and the front overhang portion C3 front end portion and each of the left and right guide portions are provided. 103a, 103a are joined by hinges which can be bent around a left-right axis d (see FIG. 4). The left and right guide main parts 103a, 103a have a symmetrical structure, and each guide main part 103a has a left-right surface 104a and a vertical surface 104b which are long in the front-rear direction, and as shown in FIG. An inner front-rear side edge g is formed of a front-rear tube member, and an upper portion of a peripheral surface of the tube member is formed as a narrow-width inclined sliding surface portion h. The pair of narrow-width inclined sliding surfaces h, h are arranged in parallel, and the length in the front-rear direction is about several times the diameter of the spherical part t3, specifically, for example, 30 cm or more (preferably about 50 cm). The onion is separated in the left-right direction by a distance (for example, about 40 to 50 mm) smaller than the diameter of the spherical part t3 and larger than the diameter of the neck. At this time, the space 105 long in the front-rear direction formed between the pair of narrow slanted sliding surfaces h, h functions as a crop feed passage.
[0062]
The left and right guide main portions 103a, 103a are joined at the longitudinally intermediate positions by a gate-shaped member 106 to form the left and right guide main portions 103a, 103a integrally. The gate-shaped member 106 is formed so that onions can pass through the inside thereof, and the front of the top surface 106a projects forward at an inclination angle larger than the inclination angle of the narrow-width inclined sliding surface portion h. The extended portion 106b is formed so that the left and right narrow inclined sliding surface portions h, the beard root t2 of the onion sliding on the upper surface of the h and the like are not entangled with the top surface 106a. Also, bent rod members 107, 107 are fixed to the front edges of the left and right narrow slanted sliding surfaces h, h, in a projecting manner and in alignment with the left and right facing surfaces 104a, 104a. The guide sides i, i (see FIG. 4) of 107, 107 are positioned so that their horizontal distance gradually increases forward, and the foliage t1 from the front side of the crop feed passage 105 to the inside thereof. Insertion is easy.
[0063]
In addition, bolts 108, 108 with handle portions are screwed into the middle portions of the vertical surface portions 104b, 104b of the left and right guide main portions 103a, 103a. Front protrusions 110, 110 and rear protrusions 111, 111 are formed at two places where separate bolts 109 with handle portions are screwed, and the bolts 109 with handle portions are formed on the left and right sides. The screwing portion and any one of the protrusions 110 or 111 are connected by a bolt with handle 108, a bolt with handle 109, and an elongated connecting plate 112. At this time, when the threaded portion of the bolt with handle 108 and the projection 110 on the front side are connected by an elongated connecting plate 112, the guide body 103 projects forward as shown in FIG. 14 and FIG. When the bolt 109 with handle and the rear protrusion 111 are connected by the elongated connecting plate 112, the guide body 103 is bent as shown in FIG.
[0064]
At the front end of each elongated coupling plate 112, as shown in FIG. 17, there is formed a through-hole 112a elongated in the longitudinal direction thereof, and the through-hole 112a is formed in a plurality of portions formed in the longitudinal direction thereof. It has a notch j for latching, and the bolt of the bolt 108 with a handle is inserted and latched in an arbitrary one of the plurality of notches j for latching. A circular hole 112b through which the bolt 109 with a handle is inserted is formed at the rear end of the plate 112, and the bolt 109 with the handle inserted through the circular hole 112b is provided with front and rear protrusions 110 on each of the left and right sides. It is screwed to any one of 111. At this time, the angle of inclination of the guide body 103 is finely adjusted by changing the notch j for latching the bolt 109 with the handle to the notch j for latching at another position.
[0065]
Next, a description will be given of a usage example of the above-described characteristic portion and an operation of each portion when preparing an onion that is dug up on a ridge of a field and dried in the sun for an appropriate time.
The guide body 103 is moved to the one end of the ridge so that the aircraft in the storage posture as shown in FIG. 16 can move forward to the other end of the ridge, and the guide body 103 moves from the engine 1 to the traveling device A. The power transmission is interrupted and the running of the aircraft is temporarily stopped while the engine is operating. Thereafter, the support stay 19 is shortened to fix the front overhang portion C3 in a slightly downward posture, and the bolt 109 with the handle is removed from the rear protrusion 111 to move the guide body 103 to the left-right axis. d and d (refer to FIG. 4), and the bolt 109 with a handle is screwed onto the front protrusion 110, and the rear end of the elongated coupling plate 112 is connected to the front protrusion. The guide body 103 is brought into a usable state as shown in FIGS. 14 and 15.
[0066]
Next, the worker picks up each onion on the ridge and picks up onions on the left and right to the point between the tips of the narrow slanted sliding surfaces h and h, or on the ridge, and removes each one on the left and right. It is sequentially inserted into the portion between the leading ends of the width-shaped inclined sliding surfaces h, h. This insertion is performed by first holding the spherical portion t3 of the onion in an inverted posture by hand, and then pushing its neck into the front end portion of the left and right narrow sloped sliding surface portions h, h. The onion inserted as described above supports the spherical portion t3 near the neck on the left and right narrow slanted sliding surfaces h, h while supporting the inverted posture by the action of gravity. Swiftly moves forward and downward.
[0067]
In such an onion insertion process, as long as there is a space where the onion is located in the crop feed passage 105, the onion to be inserted next is the same as the transport capacity of the spherical portion supporting and transporting mechanism 6 and the stem pulling belt mechanism 7. Regardless, it can be inserted without waiting time. Therefore, if the crop feed passage 105 is long enough to support, for example, four onions simultaneously as shown in FIG. 18, there is no waiting time until the four onions are simultaneously supported on the crop feed passage 105. Onions can be inserted continuously.
[0068]
Among the onions inserted in this way, the one located at the lowest position on the crop feed passage 105 reaches the crop transport start point p1 without the need for power or artificial force due to the action of gravity, and has reached here. The onion is transported by a transporting means such as the spherical portion supporting transport mechanism 6 to the preparation device C, which is a main processing section, via the transport path of the front overhang portion C3, and the preparation process is performed as described herein.
[0069]
The onion that has reached the crop transport start point p1 via the guide body 103 is not always in an appropriate inverted posture due to the influence of the sliding movement thereof, but is transported by the spherical portion support transport mechanism 6 or the like in the front overhang portion C3. Each onion conveyed by the means is supported and conveyed in a state where the distance between the onions is made large and the interference of the onions hardly occurs. And the beard root t2 and the foliage t1 are appropriately cut off by the processing unit C2.
[0070]
The speed of the sliding movement of the onion on the left and right narrow slanted sliding surfaces h, h varies greatly depending on the inclination angle of the left and right narrow slanted sliding surfaces h, h and the properties of the onion. After that, the onion is damaged due to the contact between the onions or the onion and the guide body 103 or the front overhang portion C3. Therefore, the operator, while observing the situation at the site, reduces the inclination angle of the guide body 103 when the sliding movement speed is too large to reduce that of the left and right narrow inclined sliding surface portions h, h. On the other hand, if the sliding movement of the onion on the left and right narrow inclined sliding surfaces h, h stops or the speed of the sliding movement does not stop but is too small, the onion cannot be supplied efficiently. In such a case, the inclination angle of the guide body 103 is increased to increase the inclination angle of the left and right narrow inclined sliding surfaces h.
[0071]
The height of the tips of the left and right narrow inclined sliding surfaces h, h is important for easily inserting the onion into the crop feed passage 105, and this height is optimal for the physique of the actual worker. It needs to be large. However, when the inclination angle of the guide body 103 is changed as described above, the height of the tip of the left and right narrow inclined sliding surface portions h, h also changes. It is necessary to change the height of the crop transport start point p1 to be the optimum size for both the narrow width sloped sliding surface portions h and the tip height of the h. Adjustment that changes only the inclination angles of h and h is not enough. In this case, the support stay 19 is expanded and contracted to adjust the inclination angle of the front extension C3 and to change the inclination angle of the guide body 103 with respect to the front extension C3.
After picking up all the onions present on the ridge near the front side of the machine and supplying it to the crop feed passage, the clutch lever R of the traveling transmission system provided on the side of the machine is temporarily engaged to operate the machine appropriately. The onion is advanced by a distance and then stopped again. At this point, the onion existing near the front side of the machine is picked up and supplied into the crop feed passage 105, and the same processing is repeated thereafter.
[0072]
The above embodiment can be modified as follows.
That is, the star wheels 26, 27, and 34 may be provided as needed and may be omitted.
In particular, when the star wheel 34 is omitted, it is preferable that the first cutting device E be as close as possible to the rotation fulcrum shaft 20, thereby shortening the overall length of the fuselage.
In addition, if the onion to be adjusted is of a type having a short foliage, the first cutting device E may be omitted.
[0073]
【The invention's effect】

In short, the supply of spherical crops can be performed quickly and economically by a simple batch processing method. As a result, the preparation processing capability of the processing device section C2 is fully exhibited, and efficient preparation processing can be performed. Further, when supplying the spherical crop to the preparation device C, the worker waits while holding the spherical crop picked up from the upper surface of the ridge until the spherical crop located at the crop transport start point p1 is taken in by the spherical part supporting and transporting mechanism 6. This eliminates the need to perform the operation, so that the fatigue of the worker is reduced.

Therefore, the properties of the spherical crops supported by the pair of parallel narrow slanted sliding surfaces h, h can be adjusted. Irrespective of the above, it is possible to sequentially slide in the optimum state by gravity to the crop transport start point p1.
[0076]
According to the fourth aspect, the same effect as the third aspect of the invention can be obtained, and the following effect can be obtained. That is, while the body is moved forward, the ground ahead of the body is obtained. It is possible to efficiently perform the manual operation of picking up the spherical crops dug up and feeding the crops to the crop support sliding supply means C4, and to move the pair of narrow slanted sliding surfaces h, h around the left and right axes d, d. By swinging greatly, the overall length of the machine body when the crop supporting sliding supply means C4 is not used can be shortened.
[0077]
According to the fifth aspect, the same effect as that of the fourth aspect can be obtained, and the following effect can be obtained, that is, the crop transfer starting point is controlled by the crop supporting slide supply means C4. The spherical crop supplied up to p1 has its inverted posture not necessarily in a stable state, but in the process of being conveyed through the front overhang portion C3, the inverted posture can be stabilized, and thereafter, Can be suitably performed. Further, by changing the inclination angle of the front projecting portion C3 which can swing about the left-right axis 20 at the front end of the body main body C, the height of the crop insertion position to the crop supporting slide supply means C4 is changed by a pair. Optimal for on-site workers without changing the inclination angle of the narrow sloped sliding surfaces h, h, that is, without impairing the smoothness of the sliding movement of the spherical crop on the narrow sloped sliding surfaces h, h. It can be as large as it should be.
[0078]
According to the sixth aspect, the same effect as that of the fifth aspect can be obtained with respect to the second, third, or fourth aspect of the invention.
