【発明の属する技術分野】
本発明は、玉葱などの球状作物の茎葉部先側部分及び又はヒゲ根を切り離すものとなされた球状作物調製機及び、これに装着される付加案内体に関する。
【0002】
【従来の技術】
順次に投入される球状作物から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処理し、続いてその球状部を排出シュータを通じて機体左右の任意な一側へ排出するように作動するものとなされ、前記排出シュータが前方から前記球状部を供給される受入部の左右各側部からこれの内方空間と連通された状態で斜め下方へ延出された一対の排出筒部を備えるほか前記受入部内の前記球状部を任意に選択した何れか一方の排出筒部内へ向けて排出させるための排出経路択一機構を備えたものとなされた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、調製処理された後の球状部が排出シュータの受入部内に送り込まれるが、このとき、球状部と一緒にこれに付着した土砂、ヒゲ根及び表皮片も受入部内に投入されるようになり、このように投入された土砂やヒゲ根などは排出シュータの排出筒部の内方の底面上の隅角個所(特に巾方向の後端縁近傍)に付着状に堆積するものとなり、使用時間に経過により、これが漸次に成長して該排出筒部内での球状部の落下に対して障害をなし、排出シュータによる特定個所への球状部の排出が円滑に行われないようになることがある。
【0005】
また従来では排出シュータの左右一対の排出筒部の任意な何れか一つを使用することにより、受入部に送り込まれた球状部を機体の任意な一側に落下させるようにしていたが、玉葱の生産地によっては、このようなことは必要なく、受入部に送り込まれた球状部を機体の左右側のうち特定の一側にのみへ落下させることで足りると考えられている。
本発明は斯かる問題点や実情に合理的に対応することのできる球状作物調製機や、該調製機に装着される付加案内体を提供することを目的とするものである。
【0006】
【課題を解決するための手段】
上記目的を達成するため、第一の発明に係る球状作物調製機は、次のようなものとなしてある。
即ち、第一の発明は、請求項1に記載したように、順次に投入される球状作物から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処理し、続いてその球状部を重力作用により排出シュータの受入部、排出経路択一機構個所及び、排出経路択一機構で択一された排出筒部をこの順に通過させて機体下部の左右各側のうち前記排出経路択一機構で任意に選択された一側へ排出させるものとなされた球状作物調製機において、前記排出シュータから前記排出経路切換機構を取り外すと共に、前記排出シュータの内方に、前記受入部内に前方から落下した前記球状部を特定の一側の排出筒部内へ移動させ続いて該排出筒部内の底面の後端縁から或いは前後各端縁から巾方向中央へ移動させるものとした付加案内体を装着したものである。
【0007】
この発明では、前記受入部に受け入れた球状部は付加案内体を経て前記排出筒部の底面に案内されて該底面上を転んだり滑ったりしながら機体左右の特定の一側の機外へ排出される。この際、前記付加案内体の作用により、前記球状部はたとえ前記排出筒部の底面の巾方向の端部上に一時的に位置されても巾方向の端部から巾方向中央へ移動されつつ降下して排出され、また土砂やヒゲ根などもたとえ該底面の巾方向の端部上に一時的に位置されても巾方向の後端縁から或いは前後各端縁から巾中央個所へ前記球状部の降下移動に伴う送り作用により移動されつつ降下されて排出されるようになり、したがって土砂などは前記排出筒部の底面上に堆積し難くなる。また前記排出筒部は前記受入部に受け入れた球状部を機体左右の任意な一側ではなくて予め定めれた一側にのみ排出するものとなる。
【0008】
第二の発明は、請求項2に記載したように、順次に投入される球状作物から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処理し、続いてその球状部を重力作用により排出シュータの受入部、排出経路択一機構個所及び、排出経路択一機構で択一された排出筒部をこの順に通過させて機体下部の左右各側のうち前記排出経路択一機構で任意に選択された一側へ排出させるものとなされた球状作物調製機において、前記排出シュータから前記排出経路切換機構を取り外して前記排出シュータの内方に付加案内体を装着し、該付加案内体は、前記受入部にこれの前側から後方へ向けて供給された前記球状部を機体左右側のうちの特定の一側に排出させるための特定の一つの排出筒部へ案内する起立案内面部と、前記受入部から該排出筒部の途中まで前記球状部を支持して案内する傾斜案内面部とを具備するほか、該傾斜案内面部が前記特定の一つの排出筒部の底面に沿わせられて位置され且つ該底面の後端縁から或いは該底面の前後各端縁から該底面の巾方向中央へ向けて漸次に降下される曲がり面を有するものとなされているものである。
【0009】
この発明では、前記排出シュータが機体の左右各側のうちの任意に選択された一側に前記球状部を落下させるものとなされていて断面四角形の前記排出筒部を具備するものとなされていても、該排出シュータの内方に簡易な構造の前記付加案内体を装着することにより、前記受入部内に前方から落下した前記球状部は機体の左右各側のうち前記付加案内体の形状によって定まる特定の一側に排出されるものとなり、この際、前記排出筒部の底面は前記傾斜案内面部の曲がり面の存在により巾方向中央が低くなるため、前記球状部がたとえ該底面の巾方向の後端縁近傍に一時的に位置されても前記底面の巾方向の後端縁から或いは前後各端縁からその巾方向中央へ重力作用により移動されつつ降下されて排出されるのであり、また土砂やヒゲ根などもたとえ該底面の巾方向の後端縁近傍に一時的に位置されても該底面の巾方向中央へこれらに作用する重力作用や、前記球状部の降下移動に伴う送り作用により移動されつつ降下し排出され該底面上に堆積し難くなる。
【0010】
また前記排出筒部の底面は、前記球状部がたとえ該底面の巾方向の前後各端縁の近傍に一時的に位置されても前記底面の巾方向の後端縁から或いは前後各端縁からその巾方向中央へ重力作用により移動されつつ降下されて排出されるのであり、また土砂やヒゲ根などもたとえ該底面の巾方向の後端縁の近傍或いは前後各端縁の近傍に一時的に位置されても該底面の巾方向中央へこれらに作用する重力作用や、前記球状部の降下移動に伴う送り作用により移動されつつ降下し排出され、該底面上に堆積し難くなる。
【0011】
また第三の発明は、請求項3に記載したように、順次に投入される球状作物から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処理し、続いてその球状部を排出シュータを通じて重力作用により機体左右の任意な一側へ排出するものとなされ、前記排出シュータは前方から前記球状部を供給される受入部の左右各側部からこれの内方空間と連通された状態で斜め下方へ延出された一対の排出筒部を備えるほか、前記受入部内の前記球状部を任意に選択した何れか一方の排出筒部内へ向けて排出させるための排出経路択一機構を備えたものとなされた球状作物調製機において、前記排出経路択一機構を取り外すと共に、前記受入部内に位置した前記球状部が特定側の前記排出筒部内へ移動するのを規制する起立案内面部と、前記受入部内の球状部が前記特定側とは逆の側の前記排出筒部内へ移動するのを助長する傾斜案内面部とを具備した付加案内体を前記排出シュータの内方に脱着可能に設け、前記傾斜案内面部が前記逆の側の前記排出筒部の底面に沿わせられて位置され且つ該底面の後端縁から或いは該底面の前後各端縁から該底面の巾方向中央へ向けて漸次に降下される曲がり面を有するものとなされているものである。
【0012】
この発明では、前記球状部を前記排出シュータを通じて機体左右の任意な一側へ排出するように作動するものとなされており、また前記排出シュータが前方から前記球状部を落下される前記受入部の左右各側部からこれの内方空間と連通された状態で斜め下方へ延出された一対の排出筒部を備えるほか前記受入部内の前記球状部を任意に選択した何れか一方の排出筒部内へ向けて排出させるための排出経路択一機構を備えたものとなされた球状作物調製機において、先の請求項2記載の発明の作用と同様の作用が得られるのである。
【0013】
第四の発明は、請求項4に記載したように、順次に投入される球状作物から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処理し、続いてその球状部を重力作用により排出シュータを通じて機外へ排出する球状作物調製機において、前記排出シュータを前記球状部の受入部と、これの内方空間と連通されていて受入部内の前記球状部を機体一側の斜め下方へ転落させるものとした排出筒部とで形成すると共に、該排出筒部の底面の断面形状を巾方向中央の低くなされた弧状となした構成である。
【0014】
この発明では、前記受入部に受け入れた前記球状部は前記排出筒部の底面に案内されて該底面上を転んだり滑ったりしながら機体一側の機外へ排出される。この際、前記排出筒部の底面は巾方向中央の低くなされた円弧状となされているため、前記球状部はたとえ該底面の巾方向の前後各端縁に一時的に位置されても巾方向の端部から巾中央へ重力作用により移動されつつ降下し排出されるのであり、また土砂やヒゲ根などもたとえ該底面の巾方向の端部に一時的に位置されても巾方向の前後各端縁から巾方向中央へこれらに作用する重力作用や、前記球状部の降下移動に伴う送り作用により移動されて排出され、該底面上に堆積し難くなる。また前記排出筒部は前記受入部に受け入れた前記球状部を機体の一側にのみ排出するものであり、その構造は比較的簡易且つ安価なものとなる。
【0015】
上記した各発明は次のように具体化するのがよい。
即ち、請求項5に記載したように、前記排出シュータから排出される前記球状部が落下するように位置されたコンテナを支持するコンテナ支持部が、機体側部に起立状に固定されて前記コンテナの機体側の側面部を受けめるものとした側面支持枠と、該側面支持枠に雌雄嵌合手段を介して係着され且つ直接に人為力を付与されるのみで脱着され且つ前記コンテナの底面部を支持するものとした底面支持枠とで形成されている構成となす。
これによれば、前記側面支持枠及び前記底面支持枠がコンテナを安定的に支持するものとなり、また前記底面支持枠の不使用時には前記底面支持枠が簡便に機体から取り外されて前記底面支持枠と他物の衝突とが回避されて使い勝手のよいものとなる。
【0016】
さらに好ましくは、請求項6に記載したように、起立姿勢状態となされた前記底面支持枠が、前記側面支持枠から取り外された該底面支持枠に直接に人為力を付与するのみにより、前記側面支持枠に添わせられた状態で脱着可能に係着される構成となす。これによれば、機体から取り外された前記底面支持枠が簡便に前記側面支持枠に添わせられた状態で該側面支持枠に支持されるものとなり、このようにすれば前記底面支持枠が機体から大きく張り出すものとならず他物との衝突を防止される。また前記底面支持枠の使用時には簡便に機体に略水平状に係着されるものとなり、使い勝手のよいものとなる。
【0017】
また請求項7に記載したように、前記側面支持枠が前記排出筒部の下端部に揺動変位可能且つ脱着可能に装着された延長排出樋の揺動変位時に該延長排出樋と干渉しないように装設されると共に、該延長排出樋が起立姿勢状態となされて格納されたとき、前記底面支持枠が起立姿勢状態となされて前記側面支持枠に添わせられた状態で係着される構成となす。
【0018】
これによれば、前記延長排出樋が前記傾斜排出樋部をさらに先方へ延長する状態となされたとき、前記排出筒部から排出される前記球状部はさらに前記延長排出樋に案内されて機体からかなり離れた位置、例えば機体の走行している畦の隣の畦上に落下させることができるものとなる。該延長排出樋の揺動時や使用時に、機体に装着された状態の前記底面支持枠が該延長排出樋と干渉して障害をなすことあるが、前記底面支持枠は機体から取り外されることにより何らの障害をも生じさせないのであり、しかも前記底面支持枠は簡便に脱着されて使い勝手のよいものとなる。
【0019】
上記した付加案内体は、一体構造体として作成するのが排出シュータに装着する上で便利であり、この際は、請求項8に記載したように、前後方向巾の一側端から或いは各側端から前後方向の巾中央へ向けて漸次に低くなる断面形状を有し左右方向へ傾斜されている傾斜案内面部と、該傾斜案内面部の上端の左右方向巾の略全範囲に起立状に位置されていて後方へ向かうに伴って該傾斜案内面部の下端部の存在する側の左右方向へ漸次に変位するような案内面となされている起立案内面部とを備えた構成となす。
【0020】

【0021】
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。
【0022】
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が開設されている。
【0023】
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。
【0024】
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。
【0025】
図2、図3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4参照)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。
【0026】
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上方へ揺動された状態に折曲して格納することができる。
【0027】
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。
【0028】
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がそれぞれ取付けられ、前後のVプ−リ22、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。
【0029】
また挟持搬送機構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。
さらに前方張出部C3の先端からは作物支持滑り供給手段C4が前方へ張り出されており、該作物支持滑り供給手段C4は底面を球状部の直径よりも小さい距離だけ離間された左右一対の平行な細幅状傾斜滑り面部を有し、これら細幅状傾斜滑り面部の間に前方から倒立姿勢の球状作物の球状部t3と茎葉部t1の境目部分(首部)を挿入されて直状に配列された球状作物をこれら細幅状傾斜滑り面部により同時に支持し重力作用により後下方へ滑り変位させるものとなされている。
【0030】
一方、図2、図3及び図4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。
【0031】
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。
【0032】
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。
【0033】
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34、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。
【0034】
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。
【0035】
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。
【0036】
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8及び図9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。
【0037】
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。
【0038】
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、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。
【0039】
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。
【0040】
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。
【0041】
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。
【0042】
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。
【0043】
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。
【0044】
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3、図8及び図9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。
【0045】
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。
【0046】
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。
【0047】
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。
【0048】
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。
【0049】
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。
【0050】
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。
【0051】
この際、前記コンベアベルト64の外周には、図4に示すように同ベルト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。
【0052】
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3、図8及び図9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。
【0053】
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TK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。
【0054】
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TK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。
【0055】
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ている。
【0056】
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。
【0057】
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。
【0058】
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。
【0059】
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。
【0060】
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排出シュータ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から排出シュータ70内に落下され、受口70aの下方位から図10に示す左右の排出筒部70L、70Rのいずれかに案内されてその外方端の送出口70bから機外に送出されるようになっている。
【0061】
図10〜図12にみられるように、排出シュータ70は、左右方向の中央部位に位置する受入部70Aの下端部から左右に排出筒部70L、70Rを分岐させて形成され、左右排出筒部70L、70Rの分岐部下底壁70bの上面側に排出経路を切り換える機構が形成されているのであって、即ち、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を設けている。
【0062】
そして、排路切換板76は、排出シュータ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、左側の排出筒部70Lを閉塞し右側の排出筒部70Rを受入部70Aに連通させる左倒れ位置(図9の実線図示位置)と、右側の排出筒部70Rを閉塞し左側の排出筒部70Lを受入部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。
【0063】
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部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部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、受入部70Aの前面側に開設されている。
【0064】
排出シュータ70の左右の排出筒部70L、70Rの送出口70bから機外に送出された球状部t3は例えば図15及び図16に示すように機体側部に装設された詳細を後述するコンテナ支持部84に支持された上面開放型のコンテナCTに収容させるのである。
【0065】
排出シュータ70の左右の排出筒部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してある。この延長排出樋78、78はコンテナCTを使用しないで球状部t3を圃場の地面上に直接に放出させるときに使用するもので、先寄り個所には門形部材78a及び張出部材78bを介して緩衝用ゴム垂れ78cが設けてある。
【0066】
次に本発明に係る特徴部分について説明する。
図11及び図12に示すように、排出シュータ70の受入部70Aの内方及び一方の排出筒部70Rの内方に付加案内体80を固定させている。該付加案内体80は傾斜案内面部80Aと起立案内面部80Bとを主要部としており、それぞれは次のようになされている。
【0067】
図13及び図14に示すように、傾斜案内面部80Aは受入部80Aの内方から排出筒部70Rの長さ途中まで球状部t3を支持して案内するもので、特定の一つの排出筒部70Rの底面gに添わせられて位置され、該底面gの後端縁g1から該底面gの巾中央へ向けて漸次に降下される曲がり面h1と、該曲がり面h1に連続され前後方向へ水平となされた平面h2とを有し、一枚の板部材を屈曲して形成されたものとなされ、下端h3は排出筒部70Rの出口に出来るだけ近接させるのがよいが、排出筒部70Rの底部g長さの半分程度の個所に位置させても差し支えないものである。なお、前縁の長さ途中には固定片80aが下向きに突設されている。
【0068】
そして起立案内面部80Bは、受入部70A内に供給された球状部t3を機体左右側のうちの特定の一側(図示例では右側)に排出させる特定の一つの排出筒部70Rの内方へ案内するもので、傾斜案内面部80Bの巾方向個所の全範囲に起立状に位置されていて後方へ向かうに伴って傾斜案内面部80Bの下端部の存在する側の左右方向へ漸次に変位するような案内面iを備えたものとなされており、傾斜案内樋80Aの上端h4の巾方向の全範囲から前後向き起立平板81を固着すると共に、該前後向き起立平板81の右側個所に後方へ向かうに伴って右側へ変位する傾斜起立平板82を傾斜案内部80Aと前後向き起立平板81との間に固着して形成されている。この際、傾斜起立平板82は前後向き垂直面に対して凡そ30度〜45度程度に傾斜させるのがよい。
【0069】
上記した付加案内板80の装着は次のように行われる。
先ず、図10において、排出シュータ70の排出経路を切り換えるための機構を取り外すのであり、具体的には排出シュータ70から回動支点軸75を抜き取り、排出シュータ70の内方から受口70aや送出口70bを通じて排路切換板76や補助板77L、77Rなどを外方へ取り出す。次に上記のように一体構造となされた付加案内体80を右側の排出筒部70Rの送出口70bを通じて排出シュータ70内の上端個所まで押し入れて位置決めし、この状態の下で、先に回動支点軸75の挿通されていた排出シュータ70前面壁の透孔に挿通させたボルト83と固定片80aとを介して付加案内体80の全体を締結固定させる。この際、図2に示す処理装置部C2のカバー5の一部を開放すると、排出コンベア61の上方が、第三切断装置Gで切断された茎葉部t1の落下スペースとなされて比較的大きい空間が存在するため、そのほかの部材を取り外さないでも、所要の作業が容易に行えるのである。
【0070】
また機体の左右各側には図11、図15〜図21に示すように、排出シュータ70の左右の送出口70b、70bから排出される球状部t3を受け入れるように位置されたコンテナCTや、他のコンテナCTを支持するためのコンテナ支持部84が左右対称状に設けられており、該コンテナ支持部84は図12に示すように、機体側部に起立状に固定されてコンテナCTの機体側の側面部jを受けめるものとした側面支持枠84Aと、該側面支持枠84Aに雌雄嵌合手段85を介して係着され直接に人為力を付与されるのみで脱着されるものでコンテナCTの底面部を支持するものとした底面支持枠84Bとを備えている。
【0071】
側面支持枠84Aは図11、図15〜図17、及び図19に示すように、上下一対の比較的長い前後向き管部材86a、86bを4本の縦向き管部材87a、87b、87c、87dで結合すると共に、上側の前後向き管部材86bの前後各端部に、自走車の車体Bと同体状に固着された支持部材n1にボルト固定される固定片88a、88bを固着され、また下側の前後向き管部材86aの長さ方向略中央個所の周面上部に、走行装置Aのトラックフレームと同体状に固着された支持部材n2にボルト固定される固定片88cを固着されると共に、下側の前後向き管部材86aの前後端部と長さ方向略中央個所に雌雄嵌合手段85の一部をなす受部85a、85b、85cを形成したものとなされている。
【0072】
この際、受部85a、85bは左右向きとなされた縦向き支持板部材89a及び縦向き係止板部材89bとからなり、縦向き支持板部材89aの上辺個所には支持用凹みm1が形成されている。そして縦向き支持板部材89a及び縦向き係止板部材89bの間には水平状の係止平板89cが架設状に固着してあり、該係止平板89cには位置調整用ボルト89dが螺着されている。また受部85cは左右向きとなされた縦向き支持板部材からなり、上辺個所には先の支持板部材89aと同様に支持用凹みm1が形成されている。
【0073】
底面支持枠84Bは図11、図15、図17及び図18に示すように、前後各側辺部90a、90bと前後向き中央辺部90cとからなるコ字形管部材90を形成して、前後一対の側辺部90a、90bの自由端寄り個所の間を前後向き管部材91で結合すると共に、該前後向き管部材91と前後向き中央辺部90cとの間を2本の左右向き管部材91a、91bで結合し、また各側辺部90a、90bの前後向き中央辺部90c寄り個所にこれら側辺部90a、90bと平行な軸部材92を固着して該軸部材92に比較的短いアーム部材93を軸部材92回りの揺動自在に嵌着すると共に、該アーム部材92の先部に側辺部90a、90bの自由端側へ向かう係入軸部材94を固着したものとなされている。この際、前後の各側辺部90a、90bの自由端個所と、前後向き管部材91の各端部とが前記雌雄嵌合手段85の一部をなすものである。
【0074】
次に本実施例に係る調製機の使用例及び各部の作用について説明する。
作業に先立って、側面支持枠84Aに底面支持枠84Bを図15に示す状態に支持させるのであり、これには、先ず底面支持枠84Bを前後向き姿勢で機体側が低くなるように左右傾斜させた状態の下で水平コ字形管部材90の各側辺部90a、90bの自由端個所を各受部85a、85cの縦向き支持板部材89a及び縦向き係止板部材89bの間で係止平板89cの下側個所に挿し込むのであり、この挿し込み状態のまま前後向き管部材91を受部85a、85cの縦向き支持板部材89aや受部85bの支持用凹みm1に上方から嵌め込み、この後、底面支持枠84Bを前後向き管部材91回りの下方へ揺動させて略水平姿勢となす。
【0075】
この際、底面支持枠84Bは機体側が少し低くなるような左右傾斜状態となされるが、この左右傾斜状態の左右傾斜角度を変更調製するときは位置調整用ボルト89dのねじ込み量を変化させるのであり、これにより該ボルト89dはその下端で各側辺部90a、90bの自由端個所の押し下げ量を変化させるものとなり、この押し下げ量が大きくなったときは底面支持枠84Bの左右傾斜角度は増大し、逆にそれが小さくなったときは底面支持枠84Bの左右傾斜角度が減少する。
【0076】
このように装着された底面支持枠84Bの上面に図20に示すようにコンテナCTを載せる。このとき底面支持枠84Bの左右傾斜がコンテナCTの機体側の側面部jを重力作用により側面支持枠84Aに密接させるものとなってコンテナCTはその位置を正確に保持される。
【0077】
次に、この状態となされた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1の作動状態下で一時的に機体の走行を停止させる。この際、前方張出部C3や作物支持滑り供給手段C4は図20に示すような状態となす。
【0078】
この状態の下で、作業者は畦上の玉葱の一つづつを拾い上げて作物支持滑り供給手段C4内へ順次に挿入する。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、次にその首部を作物支持滑り供給手段C4の下面をなす左右の細幅状傾斜滑り面部の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に支持されて重力作用により倒立姿勢を保持しつつこれら左右の細幅状傾斜滑り面部上を前下方へ速やかに滑り移動する。
【0079】
このように挿入された玉葱のうち、左右の細幅状傾斜滑り面部間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。
【0080】
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支持滑り供給手段C4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。
【0081】
調製装置Cでヒゲ根t2や茎葉部t1を切断除去された後の球状部t3は受樋69に案内されて、受口70aを通じて受入部70Aの内方の後方へ向け落下する。このとき、第2切断装置Fで切断されたヒゲ根t2、球状部t3に付着した土砂、及び、球状部t3の表皮などの一部が球状部t3と一緒に受入部70A内に入り込むことは避けられない。そして、受入部70A内に後方へ向け落下した球状部t3は付加案内体80の起立案内面部80Bを形成した傾斜起立平板82の左右傾斜個所に衝突して右方へ向かう外力を付与されて右斜め後下方へ案内されるのであり、また起立案内面部80Bは球状部t3が左側の排出筒部70L内へ落下するのを阻止するのである。

このように案内された球状部t3は、重力作用により、傾斜案内面部80Aの曲がり面h1個所に到達し、続いて右下方へ落下しつつ曲がり面h1の案内作用により排出筒部70Rの底面gの前縁側へ向け移動し、以後、底面gの後端縁に近づくことなく底面g上を降下し、やがて送出口70bから外方へ出てコンテナCT内に落下する。このような球状部t3の移動の一方で、受入部70A内に侵入した土砂、玉葱のヒゲ根t2及び、玉葱の表皮なども球状部t3と同様に、傾斜案内面部80Aの曲がり面h1個所に到達し、続いて右下方へ落下しつつ曲がり面h1の案内作用により排出筒部70Rの底面gの前縁側へ向け移動し、以後、底面gの後端縁に近づくことなく底面g上を降下するのであり、このとき、この土砂などの移動は球状部t3に較べて停滞し易くて排出筒部70Rの底面gに付着して滞積しがちであるが、球状部t3の移動によってその降下移動を効果的に促進されるため、停滞することなく円滑に行われるものとなる。
【0083】
玉葱の調整処理が終了して底面支持枠84B上のコンテナCTが他所へ移動された後は、底面支持枠84Bは側面支持枠84Aから離脱させるのであり、このときは底面支持枠84Bを側面支持枠84Aに装着するときの逆の手順により行われる。そして、側面支持枠84Aから分離された状態の底面支持枠84Bは前後向きの起立姿勢となして側面支持枠84Aに添わせた状態で持ち上げ、左右の係入軸部材94、94を側面支持枠84Aの左右の縦向き管部材87a、87dの上端部の内孔に上方から係入させるのであり、これにより図11に示すように底面支持枠84Bは側面支持枠84Aに密状に添わせられた状態となって安定的に支持される。この状態では機体の全巾が縮小化されて交通や格納に便利となる。
【0084】
調整装置Cで調整処理された後の球状部t3をコンテナCTに収容しないで、地上に直接に落下させたい場合があるが、このときは底面支持枠84Bは側面支持枠84Aから取り外しておき、図16に仮想線で示すように排出筒部70Rに延長排出樋78を装着して、排出筒部70Rを直状に延長した状態となす。これにより、排出筒部70Rの送出口から排出された球状部t3などは延長排出樋78に案内されて、例えば隣接した畦上に落下するものとなる。
【0085】
上記実施例は次のように変形することができる。
即ち、図10に示す排出シュータ70の一方の排出筒部70Rを切除したものとなし、残された排出筒部70Rの底面gの全長範囲の断面形状を巾方向中央の低くなされた弧状となす。これによっても付加案内体80と同様な作用が得られる。
【0086】
また先の付加案内体80では傾斜案内面部80Aは後端縁にのみ曲がり面h1を具備したものとなしたが、これに代えて、その前端縁にも対称状に曲がり面h1を形成することもできるのであり、このようにすれば、排出筒部70R内を降下移動する球状部や土砂などはたとえ前後各端縁に一時的に位置しても重力作用によりその底面の巾方向中央に移動されつつ降下するものとなり、したがって排出筒部70R内での土砂などの降下移動は一層、効果的に行われ、排出筒部70R内での土砂などの堆積はさらに確実に防止されるものとなる。

[Problems to be solved by the invention]
In the above-mentioned conventional spherical crop preparation machine, the spherical part after the preparation treatment is sent into the receiving part of the discharge chute. At this time, the sediment, beard root and epidermis pieces adhered to the spherical part together with the spherical part are also received. The sand, beard roots, etc., which have been thrown in this way, adhere to the corners on the bottom surface inside the discharge cylinder of the discharge shooter (especially near the rear edge in the width direction). As the time elapses, the spheres gradually grow and obstruct the fall of the sphere in the discharge cylinder, and the discharge shooter smoothly discharges the sphere to a specific location. You may not be able to do so.
[0005]
Conventionally, the spherical portion fed into the receiving portion is dropped to an arbitrary side of the machine body by using any one of a pair of left and right discharge cylinder portions of the discharge shooter. Depending on the production area, this is not necessary, and it is considered that it is sufficient to drop the spherical portion sent to the receiving portion to only one of the left and right sides of the body.
An object of the present invention is to provide a spherical crop preparation machine capable of reasonably coping with such problems and circumstances, and an additional guide attached to the preparation machine.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, a spherical crop preparation machine according to the first invention is as follows.
That is, in the first invention, as described in claim 1, a preparation treatment is carried out so as to cut off the foliage tip side portion and / or the beard root from the spherical crops which are sequentially input, and then the spherical part is gravity-driven. By operation, the discharge chute is passed through the receiving section of the discharge chute, the discharge path selection mechanism, and the discharge cylinder section selected by the discharge path selection mechanism in this order, and the left and right sides of the lower part of the machine are used by the discharge path selection mechanism. In the spherical crop preparation machine that is to be discharged to an arbitrarily selected one side, the discharge path switching mechanism is removed from the discharge shooter, and inside the discharge shooter, the fall falls from the front into the receiving unit. With the additional guide body attached, which moves the spherical portion into the specific one-sided discharge cylinder portion, and then moves from the rear edge of the bottom surface in the discharge cylinder portion or from each of the front and rear edges to the center in the width direction. is there.
[0007]
In the present invention, the spherical portion received by the receiving portion is guided to the bottom surface of the discharge cylinder portion via the additional guide body, and is discharged to the outside of the machine on one side on the right and left sides of the body while rolling or sliding on the bottom surface. Is done. At this time, due to the action of the additional guide, the spherical portion is moved from the widthwise end to the widthwise center from the widthwise end even if it is temporarily positioned on the widthwise end of the bottom surface of the discharge cylinder portion. Even if earth and sand, mustache roots, etc. are temporarily located on the widthwise end of the bottom surface, the spherical shape is moved from the rear edge of the width direction or from the front and rear edges to the center of the width. As a result of the downward movement of the portion, the portion is moved down and discharged while being moved, so that earth and sand and the like hardly accumulate on the bottom surface of the discharge tube portion. Further, the discharge cylinder portion discharges the spherical portion received by the receiving portion to only one predetermined side, not to any one of the right and left sides of the machine body.
[0008]
In the second invention, as described in claim 2, preparation treatment is performed so as to separate the foliage tip part and / or mustache root from the spherical crops which are sequentially fed, and then the spherical part is subjected to gravity action. The discharge chute is allowed to pass through the receiving section of the discharge chute, the discharge path selection mechanism, and the discharge cylinder section selected by the discharge path selection mechanism in this order, and arbitrarily selected by the discharge path selection mechanism on the left and right sides of the lower part of the machine. In the spherical crop preparation machine that is to be discharged to the selected one side, the discharge path switching mechanism is removed from the discharge shooter, and an additional guide is mounted inside the discharge shooter, and the additional guide is An upright guide surface portion for guiding the spherical portion supplied from the front side to the rear portion of the receiving portion toward the rear to a specific one discharge cylinder portion for discharging the spherical portion to a specific one of the left and right sides of the fuselage; From the receiving section to the discharge tube And an inclined guide surface portion that supports and guides the spherical portion halfway through, and the inclined guide surface portion is located along the bottom surface of the specific one discharge cylinder portion, and the rear end edge of the bottom surface Or from the front and rear edges of the bottom surface toward the center in the width direction of the bottom surface.
[0009]
According to the present invention, the discharge chute is configured to drop the spherical portion to one of the left and right sides of the body which is arbitrarily selected, and includes the discharge cylinder having a rectangular cross section. Also, by mounting the additional guide body having a simple structure inside the discharge shooter, the spherical portion dropped from the front into the receiving portion is determined by the shape of the additional guide body on each of the left and right sides of the body. At this time, the center of the bottom surface of the discharge cylinder portion in the width direction is lowered due to the presence of the curved surface of the inclined guide surface portion. Even if it is temporarily located in the vicinity of the rear edge, it is dropped and discharged from the rear edge in the width direction of the bottom surface or from the front and rear edges to the center in the width direction while being moved by gravity. And mustache root Even if it is temporarily located near the rear edge of the bottom surface in the width direction, it moves down to the center in the width direction of the bottom surface while being moved by the gravitational action acting on them and the feeding action accompanying the downward movement of the spherical portion. And is difficult to deposit on the bottom surface.
[0010]
Further, the bottom surface of the discharge cylinder portion may be formed from the widthwise rear edge of the bottom surface or from the front and rear edges even if the spherical portion is temporarily located near each of the front and rear edges in the width direction of the bottom surface. It is dropped and discharged while being moved to the center in the width direction by the action of gravity.Also, earth and sand, mustache roots, etc. are temporarily placed near the widthwise rear edge of the bottom surface or near the front and rear edges. Even if it is located, it is lowered and discharged while being moved by the gravitational action acting on these toward the widthwise center of the bottom surface or the feeding action accompanying the downward movement of the spherical portion, and it is difficult to deposit on the bottom surface.
[0011]
According to a third aspect of the present invention, as described in claim 3, preparation processing is performed so as to cut off the foliage tip part and / or mustache root from the spherical crops which are sequentially fed, and then discharge the spherical parts. Through the gravitational action to discharge to any one of the left and right sides of the fuselage.The discharge chute is communicated from the left and right sides of the receiving portion to which the spherical portion is supplied from the front with the inner space thereof. In addition to a pair of discharge cylinders extending obliquely downward, the apparatus further includes a discharge path selection mechanism for discharging the spherical portion in the receiving portion into any one of the discharge cylinders arbitrarily selected. In the spherical crop preparation machine made, while removing the discharge route selection mechanism, the upright guide surface portion that regulates movement of the spherical portion located in the receiving portion into the discharge cylinder portion on the specific side, and Receiving An additional guide body having an inclined guide surface portion that promotes the inside spherical portion to move into the discharge cylinder portion on the side opposite to the specific side, detachably provided inside the discharge shooter, A guide surface portion is positioned along the bottom surface of the discharge cylinder portion on the opposite side, and gradually descends from the rear edge of the bottom surface or from each of the front and rear edges of the bottom surface toward the center in the width direction of the bottom surface. It has a curved surface to be formed.
[0012]
In the present invention, the spherical portion is operated to be discharged to any one of the left and right sides of the machine through the discharge chute, and the discharge chute of the receiving portion where the discharge chute is dropped from the front from the spherical portion. In addition to a pair of discharge cylinders extending obliquely downward from the left and right sides in communication with the inner space of the discharge cylinder, any one of the discharge cylinders in which the spherical portion in the receiving portion is arbitrarily selected In a spherical crop preparation machine provided with a discharge route selection mechanism for discharging toward the side, the same operation as that of the invention of the second aspect can be obtained.
[0013]
According to a fourth aspect of the present invention, as described in claim 4, the foliage tip and / or the mustache root are prepared and separated from the spherical crops which are sequentially fed, and then the spherical parts are subjected to gravity action. In a spherical crop preparation machine that discharges outside the machine through a discharge shooter, the discharge shooter is communicated with a receiving portion of the spherical portion and an inner space of the spherical portion, and the spherical portion in the receiving portion is obliquely downward on one side of the machine body. The discharge cylinder is formed so as to fall down, and the cross-section of the bottom surface of the discharge cylinder is formed to be a lower arc at the center in the width direction.
[0014]
In the present invention, the spherical portion received by the receiving portion is guided to the bottom surface of the discharge cylinder portion and is discharged outside the machine on one side while rolling or sliding on the bottom surface. At this time, since the bottom surface of the discharge cylinder portion is formed in an arc shape with a lower center in the width direction, even if the spherical portion is temporarily located at each of the front and rear edges in the width direction of the bottom surface, From the end of the bottom to the center of the width while being moved by gravity, and is discharged.Even if soil and beard roots are temporarily located at the widthwise end of the bottom surface, the front and rear in the width direction It is moved and discharged by the gravitational action acting on these from the edge to the center in the width direction or the feeding action accompanying the downward movement of the spherical portion, and it is difficult to deposit on the bottom surface. Further, the discharge cylinder portion discharges the spherical portion received by the receiving portion only to one side of the body, and has a relatively simple and inexpensive structure.
[0015]
Each of the above-described inventions may be embodied as follows.
That is, as described in claim 5, the container supporting portion for supporting the container positioned so that the spherical portion discharged from the discharge shooter is dropped is fixed to the side of the body in an upright state, and A side support frame adapted to receive the side portion on the side of the fuselage; and a container which is attached and detached to the side support frame via male and female fitting means and is detached only by being directly applied with an artificial force. And a bottom support frame that supports the bottom portion.

And the collision of other objects is avoided, so that it is easy to use.
[0016]
More preferably, as described in claim 6, the bottom support frame in the upright posture state only applies artificial force directly to the bottom support frame detached from the side support frame, so that the side surface is provided. It is configured to be detachably engaged with the support frame. According to this, the bottom support frame detached from the body is simply supported by the side support frame in a state of being attached to the side support frame. In this case, the bottom support frame is It does not protrude greatly from, and collision with other objects is prevented. Further, when the bottom support frame is used, the bottom support frame is easily attached to the body in a substantially horizontal shape, and the device is easy to use.

Under the condition, the free end portion of each side 90a, 90b of the horizontal U-shaped tube member 90 is locked between the vertical support plate member 89a and the vertical lock plate member 89b of each of the receiving portions 85a, 85c. In this state, the front-rearward pipe member 91 is inserted into the vertical support plate member 89a of the receiving portions 85a and 85c and the supporting recess m1 of the receiving portion 85b from above. Thereafter, the bottom support frame 84B is swung downward around the tube member 91 in the front-rear direction to be in a substantially horizontal posture.
[0075]
At this time, the bottom support frame 84B is inclined left and right so that the fuselage side is slightly lowered. To change the left and right inclination angle in the left and right inclination state, the screwing amount of the position adjustment bolt 89d is changed. Accordingly, the lower end of the bolt 89d changes the amount of depression at the free end of each of the side portions 90a and 90b. When the amount of depression increases, the left-right inclination angle of the bottom support frame 84B increases. Conversely, when it becomes smaller, the left-right inclination angle of the bottom support frame 84B decreases.
[0076]
As shown in FIG. 20, the container CT is placed on the upper surface of the bottom support frame 84B thus mounted. At this time, the horizontal inclination of the bottom support frame 84B causes the side surface portion j of the container CT on the fuselage side to come into close contact with the side support frame 84A by the action of gravity, and the container CT is accurately held at that position.
[0077]
Next, the aircraft in this state is moved to one end of the ridge so as to be able to move forward toward the other end of the ridge, and the power transmission from the engine 1 to the traveling device A is interrupted to stop the engine 1 from moving. The running of the aircraft is temporarily stopped in the operating state. At this time, the front overhang portion C3 and the crop support slide supply means C4 are in a state as shown in FIG.
[0078]
Under this condition, the operator picks up the onions on the ridge one by one and sequentially inserts them into the crop support sliding supply means C4. In this insertion, the spherical portion t3 of the onion is firstly held in an inverted posture by hand, and then its neck is pushed from the front into a portion between the left and right narrow inclined sliding surfaces forming the lower surface of the crop supporting sliding supplying means C4. The onion thus inserted is supported on the spherical portion t3 near the neck by the left and right narrow slanted sliding surfaces, and the left and right narrow slanted sliding surfaces are held while maintaining the inverted posture by the action of gravity. Sliding up and down quickly.
[0079]
Among the onions inserted in this way, the one located at the lowest position between the left and right narrow slanted sliding surfaces reaches the crop transport start point p1 without the need for power or artificial force due to the action of gravity. The onion arriving here is transported by a transporting means such as the spherical portion support 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 above. Will be implemented.
[0080]
After picking up all the onions present on the ridge near the front side of the fuselage and supplying them to the crop support sliding supply means C4, the clutch lever R of the traveling transmission system provided on the side of the fuselage is temporarily engaged to operate. The aircraft is moved forward by an appropriate distance and stopped again. Here, similarly to the above, the onion existing near the front side of the aircraft is picked up and supplied to the crop feed passage 105. Repeated.
[0081]
After the beard root t2 and foliage t1 have been cut and removed by the preparation device C, the spherical portion t3 is guided by the receiving trough 69, and falls toward the rear inside the receiving portion 70A through the receiving port 70a. At this time, a part of the beard root t2 cut by the second cutting device F, the earth and sand adhered to the spherical portion t3, and a part of the skin of the spherical portion t3 may enter the receiving portion 70A together with the spherical portion t3. Inevitable. Then, the spherical portion t3 that has fallen rearward into the receiving portion 70A collides with the left and right inclined portion of the inclined upright flat plate 82 forming the upright guide surface portion 80B of the additional guide body 80, and is applied with an external force directed rightward to the right. It is guided obliquely rearward and downward, and the upright guide surface portion 80B prevents the spherical portion t3 from falling into the left discharge cylinder portion 70L.
[0082]
The spherical portion t3 guided in this way reaches the curved surface h1 of the inclined guide surface portion 80A due to the gravitational action, and subsequently falls to the lower right while guiding the curved surface h1 to act on the bottom surface g of the discharge cylinder portion 70R. , And thereafter descends on the bottom surface g without approaching the rear edge of the bottom surface g, and eventually goes out of the outlet 70b and falls into the container CT. While the spherical portion t3 moves as described above, the earth and sand, the beard root t2 of the onion, the skin of the onion, and the like that have entered the receiving portion 70A are also located at the curved surface h1 of the inclined guide surface portion 80A in the same manner as the spherical portion t3. The discharge cylinder 70R moves toward the front edge of the bottom surface g of the discharge cylinder portion 70R by the guiding action of the curved surface h1 while falling to the lower right, and thereafter descends on the bottom surface g without approaching the rear edge of the bottom surface g. At this time, the movement of the earth and sand tends to stagnate as compared with the spherical part t3, and tends to adhere to the bottom surface g of the discharge cylinder part 70R and accumulate. Since the movement is effectively promoted, the movement is smoothly performed without stagnation.
[0083]
After the onion adjustment process is completed and the container CT on the bottom support frame 84B is moved to another location, the bottom support frame 84B is detached from the side support frame 84A. In this case, the bottom support frame 84B is supported on the side. The procedure is performed in the reverse order of mounting on the frame 84A. Then, the bottom support frame 84B separated from the side support frame 84A is raised in a state of standing in the front-back direction while being attached to the side support frame 84A, and the left and right engagement shaft members 94, 94 are lifted. The bottom support frame 84B is tightly attached to the side support frame 84A as shown in FIG. 11 because the bottom support frame 84B is engaged with the inner holes at the upper end portions of the left and right vertical pipe members 87a and 87d of 84A from above. It is in a state of being stably supported. In this state, the entire width of the aircraft is reduced, which is convenient for transportation and storage.
[0084]
There is a case where the spherical portion t3 after the adjustment processing by the adjustment device C is not accommodated in the container CT and is to be dropped directly on the ground. In this case, the bottom support frame 84B is detached from the side support frame 84A. As shown by the phantom line in FIG. 16, an extended discharge gutter 78 is attached to the discharge tube portion 70R, and the discharge tube portion 70R is extended straight. Thus, the spherical portion t3 discharged from the outlet of the discharge tube portion 70R is guided by the extended discharge gutter 78 and falls on, for example, an adjacent ridge.
[0085]
The above embodiment can be modified as follows.
That is, one of the discharge cylinder portions 70R of the discharge shooter 70 shown in FIG. 10 is cut off, and the cross-sectional shape of the remaining bottom surface g of the discharge cylinder portion 70R in the entire length range is formed into an arc shape with a lower center in the width direction. . With this, the same operation as that of the additional guide body 80 can be obtained.
[0086]
In addition, in the preceding additional guide body 80, the inclined guide surface portion 80A has the curved surface h1 only at the rear end edge, but instead, the inclined guide surface portion 80A also has a symmetrically curved surface h1 at the front end edge. In this way, the spherical part or the earth and sand moving downward in the discharge cylinder part 70R moves to the center in the width direction of the bottom surface due to gravity even if it is temporarily located at each of the front and rear edges. Therefore, the lowering movement of the earth and sand in the discharge cylinder 70R is more effectively performed, and the accumulation of the earth and sand in the discharge cylinder 70R is more reliably prevented. .
