Description

【0001】
【発明の属する技術分野】
本発明は、ほうれん草、小松菜、チンゲン草等の収穫に使用される歩行形野菜収穫機に関する。
【0002】
【従来の技術】
機体を支持した走行装置と、野菜を機体前部で引き抜き機体後部へ搬送するように作動する挟持搬送手段とを備えてなる歩行形収穫機としては、例えば特開平9−271242号及び特許第2796584号等がある。
【0003】
【発明が解決しようとする課題】
上記した従来の野菜収穫機のうち、走行装置が車輪となされたもの(例えば特開平9−271242号等)では、走行車輪の転がり抵抗を小さくする必要のため、その直径を一定程度以上に大きくすることから、機体高さが大きくなり、また、一対の走行車輪が畝を跨いで畝間溝を走行するように使用されるものであるときは、大きなトレッドが必要であるほか畝間溝の深さに対応して機体の地上高さを大きくなす必要があり、さらに、走行車輪が収穫中に、野菜の引き抜かれた収穫跡上を走行するものでは土面の状態によって走行車輪が土中に沈下し、安定した収穫作業が行えなくなることが生じるのである。
また、走行装置を一対のクローラ式となしたもの(例えば特許第2796584号等)では走行装置周辺の構造が重厚となり、ほうれん草等の収穫には不向きとなる。
【0004】
本発明は上記のような問題点を解消させて、ほうれん草、小松菜、チンゲン草等の野菜を合理的に収穫し得るものとした歩行形野菜収穫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、本発明では次のようになす。
即ち、請求項1に記載した発明では、機体を支持した前後向きとなされた単一のクローラ式走行装置(3)と、機体前部に圃場に条列状に植生している野菜(v)の根を土中で切断するための根切り刃体(42)と、同根切り刃体(42)で切断された野菜(v)を機体前部で引き抜き機体後部へ搬送する前後向き搬送部(21a)と、同前後向き搬送部(21a)から引き続き横向きへ搬送するものとした横向き搬送部(21b)とを有する挟持搬送手段(16)と、機体側部には、横向き搬送部(21b)の搬送終端から放出される収穫野菜(v)を収集するための収集台(35)と、機体後部に操縦ハンドル(8)とを備えた歩行形野菜収穫機であって、前記単一のクローラ式走行装置(3)の真上に前記挟持搬送装置(16)の前後向き搬送部(21a)の挟持搬送経路(d1)を概ね合致させたこととした。
【0006】
上記請求項1記載の発明において、請求項2に記載した発明では、収穫野菜(v)を収集するための前記収集台(35)を操縦ハンドル(8)側に設けた把手(35a)と操作部材(s)によりロック手段(k)を操作して、収集台(35)を前後移動固定自在に設けるとともに、機体側方への張出し長さを縮小可能となしたこととした。
【0007】
上記請求項1又は2記載の発明において、請求項3に記載したように、収集台(35)を支持する台支持アーム部材(37)と、収集台(35)の前後摺動変位を案内するための前後向き案内体(38)の下面に収納操作可能とした脚部(39)と、同脚部(39)に装着された支持輪(40)とで形成された支持手段(36)とを設けたこととした。
【0008】
【発明の実施の形態】
以下、本発明の一実施例を詳述する。図1は本発明に係る歩行形野菜収穫機を示す側面図、図2は前記収穫機の平面図、図3は前記収穫機の正面図、図4は前記収穫機の使用状態を示す側面視説明図である。
本発明の歩行形野菜収穫機は走行機体部1と、野菜処理部2からなっている。
先ず走行機体部1について説明すると、前後向きとなされたクローラ式走行装置3と、この走行装置3に支持された機体フレーム4と、この機体フレーム4の後部に固定されたエンジン5と、このエンジン5の動力をミッション6を介しクローラ式走行装置3に伝達するものとしたチェーンケース7と、機体フレーム4からエンジン5の後方へ張り出された操縦ハンドル8とを備えている。
【0009】
ここに、クローラ式走行装置3は、案内輪9、10を介し縦向き楕円状の案内軌道を形成した前後方向へ長い固定フレーム部11と、前記案内軌道に周回移動自在に掛け回されておりゴム質材等で形成された無端状のクローラ12からなる。
機体フレーム4は管部材及び板部材等を枠状に結合したもので、前記固定フレーム部11と同体状に結合されており、クローラ式走行装置3の上方に位置させてある。
チェーンケース7は案内輪9と同心に固定されたスプロケット13にチェーン14を介してエンジン5の回転を伝達するものとなしてある。
操縦ハンドル8は前端部を機体フレーム4と同体状に固定され後端部を把持部となされた左右一対の前後向き杆8a、8bからなり、各前後向き杆8a、8bには図示しない各種の操作具が装着される。
【0010】
次に野菜処理部2について説明すると、最前方に位置された分草部15と、この分草部15の後方に連続して配置され機体フレーム4の前部から後部に渡るものとなされた挟持搬送手段16と、この挟持搬送手段16の後部横側で機体フレーム4の横外方に配置された収集台手段17と、前記挟持搬送装置16の下方に配置された根切り刃手段18と、この処理部2の前部を上下変位させるための処理部高さ変更手段19を備えたものとなしてある。
【0011】
ここに、挟持搬送手段16は後上がり状に傾斜された支持枠部20と、この支持枠部20の上面側に形成された挟持搬送部21からなっている。
支持枠部20は下方へ延びるアーム部20aを有し、このアーム部20aの下部を固定フレーム部11に横向き軸g1を介して揺動自在に装着したものとなされ、また挟持搬送部21は前後向き搬送部21aと横向き搬送部21bを備えたものとなしてある。
【0012】
上記挟持搬送部21をさらに具体的に説明すると次のとおりである。
即ち、支持枠部20の前部に左右一対の前部プーリ22a、22bを設け、且つ支持枠部20の後部の左右特定箇所に3つの後部プーリ23a、23b、23cと一つの補助プーリ24を設け、支持枠部20に形成された右張出し部20aに前後一対の終端部プーリ25a、25bを設ける。
この際、これらプーリ22a、22b、23a、23b、23c、24、25a、25bは支持枠部20上面上の位置を変更調整可能となされる。
そして左側の前部プーリ22aとこれの真後ろに位置した後部プーリ23aに無端状の搬送ベルト26を掛け回し、右側の前部プーリ22bとこれに対応した後部プーリ23b及び補助プーリ24と前側の終端部プーリ25aとに比較的長い無端状の搬送ベルト27を鈎状に屈曲させて掛け回し、さらに最後部の後部プーリ23cと後側の終端部プーリ25bとの間に無端状の搬送ベルト28を横向き方向に掛け回す。
【0013】
上記した各搬送ベルト26、27、28は、内周面部をその長手方向への伸縮変形の生じ難い材料で形成し、また外周側部を、野菜の葉部を傷めないようなスポンジ質で数cm厚となされた軟質材料で形成したものとなす。
【0014】
左右の前部プーリ22a、22bの各々に一体状に固定された回転中心軸a1、a2は、支持枠部20に設けた図示しない軸受に支持させると共に、左右の前部プーリ22a、22bの近傍に野菜の葉部を掻き込むための掻込み具29を設ける。
この掻込み具29は、左右の回転中心軸a1、a2の上端と支持枠部20の下面側に達したそれら回転中心軸a1、a2の下端とに容易に弾性屈曲するものとしたゴム質のスターホイール29aを固定したものとなす。
この際、各スターホイール29aの外周端縁はその対応する搬送ベルト26、27の外周面から少し張り出した状態となされる。
【0015】
3つの後部プーリ23a、23b、23cにはエンジン5の回転をミッション6及び図示しない作業クラッチを介し伝達させ、これらプーリ23a、23b、23cを駆動プーリとして機能させる。
この際、エンジン5の回転をさらに前部プーリ22a、22bにも伝達させて、これらプーリ22a、22bをも駆動プーリとして機能させることは差し支えない。
【0016】
3つの搬送ベルト26、27、28の集合箇所には後部プーリ23a、23b、23cの円弧に基づいて三角状の空所bが形成されるが、この空所bに達した野菜の葉部に特定方向への送り力を付与するための送り力付与手段30を設ける。
このため、一つの後部プーリ23bと同体となされた回転中心軸cの上端部に容易に弾性屈曲するものとしたゴム質のスターホイール31を固定すると共に、このスターホイール31の外周縁の一定範囲箇所の外方に沿わせて円弧状の案内棒32を配置する。
この案内棒32は、支持枠部20から張り出させた図示しない支持片を介して保持させ、スターホイール31との間に野菜を挟むように作用するものとなす。
【0017】
この挟持搬送手段において、前後向き搬送部21aでは2つの搬送ベルト26、27が左右配置となって、これらの外周面が前後方向の挟持搬送経路d1を形成しており、
また横向き向き搬送部21bでは二つの搬送ベルト27、28が前後配置となって、これらの外周面が左右方向の挟持搬送経路d2を形成している。
この際、前後向き搬送部d1はクローラ式走行装置3の概ね真上に合致させる。
【0018】
3つの後部プーリ23a、23b、23cはエンジン5の回転を伝達されて特定方向へ回転し、各搬送ベルト26、27、28を矢印方向f1、f2へ同調して移動させ、また搬送ベルト26、27の移動は左右の前部プーリ22a、22bを介し左右一対のスターホイール29a、29aを回転させ、また後部プーリ23bの回転中心軸cがスターホイール31を回転させる。
この際、左右一対の前部プーリ22a、22b箇所が搬送始端をなし、前後一対の終端部プーリ25a、25b箇所が搬送終端をなす。
【0019】
分草部15は左右一対の分草板33a、33bからなり、各分草板33a、33bの後端が支持枠部20と同体状に固定されている。
この際、左右一対の分草板33a、33bは平面視先広がり状に配置され、前後向きの挟持搬送経路d1に対応した配置となされる。
【0020】
収集台手段17は機体フレーム4の右張出し部4aの下部外方へ張り出させた張出し支持手段34と、この支持手段34の上面に手操作による前後移動固定自在に装着した収集台35と、この収集台35の重量やこれに作用する荷重を支持するものとした支持手段36からなっている。
【0021】
この際、収集台35の後部には把手35aを設け、この把手35aに収集台35の前後移動を規制するためのロック手段kを係脱させるための操作部材sを付設し、前記把手35aを握った手で操作部材sを操作できる構成となす。
張出し支持手段34は、基端を機体フレーム4の右張出し部4aに支持させた台支持アーム部材37の水平箇所に収集台35の前後摺動変位を案内するための前後向き案内体38を設けたものとなし、収集台35は平面視で前後方向へ長い長方形状となし且つ底面を縦部材と横部材とを交差状に配置してなる格子面となしたものとなす。
【0022】
そして支持手段36は、台支持アーム部材37及び前後向き案内体38の下面に横向き軸g1回りの揺動及び縦軸g2回りの回動による収納操作可能となした脚部39と、この脚部39の下端部に横向き軸g3回りの回転自在に装着された支持輪40とで形成する。
【0023】
根切り刃手段18は、支持枠部20の前部左右箇所から揺動アーム部材41を横軸g4回りの揺動自在に垂下させ、これら一対のアーム部材41の下端部に前面視U型の根切り刃体42を固定させ、一方では機体フレーム4の適当箇所にエンジン5の回転を伝達されるクランク機構部43を形成し、このクランク機構部43の出力部と揺動アーム部材41の長さ途中箇所とを結合ロッド44を介して結合させ、前記出力部の上下及び前後の繰返し変位を揺動アーム部材41に伝達するものとなす。
この際、クランク機構部43及び結合ロッド44は機体フレーム4の一側に一つ設けても或いは左右各側に一対設けてもよい。
【0024】
処理部高さ変更手段19は、クローラ式走行装置3の固定フレーム部11と支持枠部20との間に伸縮駆動装置45としての電気油圧シリンダ装置を架設し、このシリンダ装置の伸縮操作により、分草部15、根切り刃体42及び、挟持搬送手段16の搬送始端等の高さを地面上一定高さ位置から地中一定深さ位置までの範囲内で任意高さに変更調整できる構成となす。
この際、支持枠部20と同体に土の存在を感知する上下二つのセンサを設け、これらのセンサのうち下側のセンサのみが土を感知するように上記電気油圧シリンダ装置を制御することにより、根切り刃体42の要部が収穫中、常に地中の一定深さを移動するようになすのがよい。
【0025】
次に上記のように構成した本実施例の収穫機でほうれん草や小松菜等の葉菜類を収穫する場合の使用例を説明する。
収穫を開始するまでの路上走行や圃場内走行では、電気油圧シリンダ装置45を伸張状態となして支持枠部20及びこれと一体となさた部位を横向き軸g1回りの上方へ揺動させることにより、分草部15、根切り刃体42及び、挟持搬送手段16の搬送始端等をクローラ式走行装置3に対し適当距離だけ上昇させ、また支持輪手段36の脚部39及び支持輪40を収納状態となした後、操縦ハンドル8の把持部を握り、クローラ式走行装置3のクローラ12にエンジン5の回転を伝達させる。
【0026】
これにより、機体は地面等に接することなく円滑に走行し、また細い通路であっても支障なく走行できる。
必要であれば支持輪手段36を使用状態に復帰させ、支持輪40が接地した状態で走行させてもよい。
走行中に進行方向を変化させる際は、操縦ハンドル8を下方へ押し下げ、機体全体の前後傾斜を変化させる。
これにより、クローラ12の接地部の後端部12aを支点としてクローラ式走行装置3の前端が浮き上がるように機体全体が姿勢変化する。
この状態の下で操縦ハンドル8を左右へ振り操作し機体を希望する向きへ変化させた後、操縦ハンドル8に付与した押下げ力を除去する。
これにより、機体は自重でクローラ12の接地部全体が接地した状態に復帰し、新たな機体の向きへ進行するものとなる。
【0027】
収穫の際の取扱いは例えば次のように行う。
即ち、図1に示すように機体を収穫すべき植生野菜の条列mに沿わせることにより挟持搬送手段16の前後向き搬送部21aの挟持搬送経路d1をその条列mに合致させると共に、図4に示すように収集台35上に適当数のコンテナn1、n2を載せてこの収集台35の把手35a及び操作部材sを手で持ってロック手段kを操作し収集台35を最後方位置へ移動させロックさせた後、エンジン5の回転をクローラ式走行装置3及び野菜処理部2に伝達させて機体を進行させると共に、電気油圧シリンダ装置45を適当に短縮作動させる。
これにより根切り刃体42は機体の重量や、根切り刃体42に作用する土からの反力により、電気油圧シリンダ装置45の作動に対応した距離だけ土中に進入するものとなる。
根切り刃体42は野菜処理部2の作動中、クランク機構部43に駆動されて横向き軸g4回りに振動し、この振動は根切り刃体42の土中への進入を促進する。
【0028】
機体の進行中、分草部15は、収穫中の条列の野菜vと、これの左右に隣接した条列の野菜vとの絡みを解すように作用する。
この際、分草部15の分草板33a、33bはほうれん草等の野菜v上部に比較的広い面で接触し、その損傷を抑制する。
【0029】
図1に示すように野菜条列mの一つの野菜v1が挟持搬送装置16の搬送始端に達したとき、左右一対のスターホイール29a、29aはこの野菜v1の上部を前後向き搬送部21aの挟持搬送経路d1に掻き込むのであり、一方では根切り刃体42の要部がこの野菜v1の根部を前後揺動しつつ切断する。
この際、根切り刃体42による切断深さは地面から数cm(凡そ2〜3cm)程度となすのがよい。
【0030】
前後向き搬送部21aで挟持搬送される野菜v上部はその傾斜に伴って徐々に上昇され遂には地面から引き抜かれるものとなる。
この際、挟持搬送手段16の搬送ベルト26、27はスポンジ質で野菜vを柔らかく挟持し、一方ではその根部が切断されているため、その引抜き時に大きな引抜き力が作用するものとならず、この野菜v上部の損傷は抑制されるのである。
【0031】
引き抜かれた野菜v上部は凡そ機体進行速度で挟持搬送経路d1の下流側へ搬送され、遂には三角状の空所b近傍に達する。
ここで、送り力付与手段30のスターホイール31はこの野菜v上部を案内棒32との間に挟み付け、これに送り力を付与する。
したがって、三角状の空所bに位置して搬送ベルト26、27、28による十分な送り力を付与されない野菜v上部であっても搬送遅れを生じることなく確実に横向き搬送部21bへ向け搬送されるものとなる。
【0032】
横向き搬送部21bはここに達した野菜v上部を挟持搬送経路d2によりその搬送終端へ向け搬送し、最終的にはその搬送終端から外方へ放出させる。
この放出された野菜v上部は根部に搬送抵抗付与手段による搬送抵抗を付与されるため、コンテナn1又はn2内に根部側が機体内方向きとなる横倒し姿勢となって落下する。
この落下は収穫の進行に伴って次々と繰り返され、コンテナ内には野菜v上部が整列された状態に山積みされる。
この山積みが適当に大きくなる毎に、収集台35を適当距離だけ前方へ移動固定させることを繰り返すのであり、これにより前後の各コンテナn1、n2には野菜v上部が整列された状態に満たされる。
【0033】
収集台35上に搬送された野菜vが多くなり、その荷重によって機体が横転倒する傾向となるときは収納状態となされている支持手段36を図3等に示すような使用状態となして支持輪40を接地させた状態に保持させ、この支持輪40に収集台35に作用する荷重を支持させる。
これにより、収集台35に大きな荷重が作用していても、機体の収穫姿勢は安定的に保持されるものとなる。
【0034】
収穫中において、クローラ式走行装置3は、根切り刃体42で膨軟になされ野菜v上部を引き抜かれる等してでこぼこになった地面上を走行するものとなるが、接地面が広いため地面に対する面圧が小さいものとなって土中に過度に沈下することはないのであり、また接地面が長いことにより機体の大きな前後傾斜を生じさせないものとなる。
【0035】
収穫中には直線走行させることが殆どであるため収穫中の機体進行方向の変更操作は微調整で済むのであって、操縦ハンドル8に左右向きの操作力を少し付与することで足りる。
なお、稀に必要となる大きなその変更操作は非収穫時の場合に準じて行う。
【0036】
収穫作業の開始時においては図5に示すように中割り収穫を行うことがあるが、この場合において支持輪40が野菜の条列に干渉するときは、支持輪42及び脚部39を収納状態となす。
即ち、脚部39を横向き軸g1回りへ凡そ90度揺動させて水平姿勢となし且つ支持輪39を縦向き軸g2回りへ90度回動させることにより支持輪手段36を水平扁平状となして収集台35の下面に沿わせるようにする。
これにより、機体は植生した野菜vを損傷させないで中割り収穫の行える状態となる。
【0037】
上記実施例は次のように変形できる。
即ち、収集台35、前後向き案内体38及び台支持アーム部材37を機体フレーム4の張出し部4aに対し左方f3への変位可能になすか、台支持アーム部材37の先寄り箇所を前後向き軸回りの上方f4へ折れ曲がり可能となすことにより、或いはこれら両者を組み合わせることにより、収集台手段17の機体側外方への張出し寸法を短くする構成となす。
前後向き案内体38に対する収集台35の前後方向への移動固定を電動モータ等の動力駆動手段により行えるものとなす。
【0038】
図6に示すように、分草部15の後部下方に、前後振動される根切り刃体42に代えて、エンジン5又は別個に設けた電気モータで縦軸g5回りへ回転駆動される円盤状の根切り刃体42を装設し、この刃体42の外周縁に形成された鋸刃状の刃で根部を切断するものとなす。
これによれば、機体に前後振動が生じず、快適な収穫作業が可能となる。
【0039】
エンジン5に代えて、電気モータを設けるのであり、これによれば排気ガスが発生せず、図5に示すようなハウスh内での作業を快適となす。
処理部高さ変更手段19を、手操作力で操作されるネジ・ナット機構等を介して必要な変更操作が行えるようになすことも差し支えない。
【0040】
さらには各部の左右配置を上記実施例のものと対称の関係となるものとして逆勝手仕様のものとなすことも差し支えない。
【0041】
【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のである。
即ち、請求項1に記載した発明では、機体を支持した前後向きとなされた単一のクローラ式走行装置(3)と、機体前部に圃場に条列状に植生している野菜(v)の根を土中で切断するための根切り刃体(42)と、同根切り刃体(42)で切断された野菜(v)を機体前部で引き抜き機体後部へ搬送する前後向き搬送部(21a)と、同前後向き搬送部(21a)から引き続き横向きへ搬送するものとした横向き搬送部(21b)とを有する挟持搬送手段(16)と、機体側部には、横向き搬送部(21b)の搬送終端から放出される収穫野菜(v)を収集するための収集台(35)と、機体後部に操縦ハンドル(8)とを備えた歩行形野菜収穫機であって、前記単一のクローラ式走行装置(3)の真上に前記挟持搬送装置(16)の前後向き搬送部(21a)の挟持搬送経路(d1)を概ね合致させたことにより、クローラ式走行装置による機体の支持は、左右一対の走行装置により機体を支持する構成のものに較べて機体の構造を簡易化させるとともに、現在収穫している野菜の条列の左右に隣接した未収穫野菜の条列に干渉することなく走行することができ、しかも、条植された野菜の中割り収穫を可能とする
また、クローラ式走行装置は全体の高さが低くても適当な走行性能が得られ、このことが機体の高さを小さくなす上で効果的に寄与し、また、接地面圧を走行車輪に較べて小さくなすため、野菜が引き抜かれて膨軟となった地面上を走行しても土中に過度に沈下することが生じないものとすることができる。
さらに、クローラ走行装置は中割り収穫中、現在収穫している野菜の条列の左右に隣接した未収穫の野菜の条列から最も離れた状態となるのであり、このことがクローラ走行装置の横幅を大きくなすことを可能とする
そして、この場合、クローラ走行装置は収穫跡を走行することになるが、この走行時のその接地部の地面に対する面圧が小さくなって土中への沈下を抑制することができる
【0042】
請求項2に記載した発明では、収穫野菜(v)を収集するための前記収集台(35)を操縦ハンドル(8)側に設けた把手(35a)と操作部材(s)によりロック手段(k)を操作して、収集台(35)を前後移動固定自在に設けるとともに、機体側方への張出し長さを縮小可能となしたことにより、請求項1のものについての効用が得られるほか、機体の左右方向巾が減少し、非収穫時における路上走行が容易に行うことができる
【0043】
請求項3に記載した発明では、収集台(35)を支持する台支持アーム部材(37)と、収集台(35)の前後摺動変位を案内するための前後向き案内体(38)の下面に収納操作可能とした脚部(39)と、同脚部(39)に装着された支持輪(40)とで形成された支持手段(36)とを設けたことにより、収集台に収穫野菜を収集したときのこれらの荷重を支持手段に支持させて操縦者の負担を減少させることができ、しかも、支持手段を使用しないときは支持輪を地面から上方へ離すことができ、これにより、中割り収穫を収穫中の条列に隣接した条列の野菜を損傷させることなく円滑に行うことができる

[0020]
The collection base means 17 is an extension support means 34 that protrudes outward from the lower part of the right extension portion 4a of the body frame 4, a collection base 35 that is mounted on the upper surface of the support means 34 so that it can be moved back and forth manually and freely. It comprises support means 36 for supporting the weight of the collection stand 35 and the load acting on it.
[0021]
At this time, a handle 35a is provided at the rear portion of the collecting table 35, and an operating member s for engaging and disengaging the locking means k for restricting the back and forth movement of the collecting table 35 is attached to the handle 35a.

At this time, one crank mechanism portion 43 and one connecting rod 44 may be provided on one side of the body frame 4 or a pair may be provided on each of the left and right sides.
[0024]
The processing unit height changing means 19 is constructed by installing an electrohydraulic cylinder device as an expansion / contraction drive device 45 between the fixed frame portion 11 and the support frame portion 20 of the crawler type traveling device 3, and by extending / contracting the cylinder device, A configuration in which the heights of the weeding unit 15, the root cutting blade 42, and the conveyance start end of the holding conveyance means 16 can be changed and adjusted to an arbitrary height within a range from a certain height position on the ground to a certain depth position in the ground. And
At this time, by providing two upper and lower sensors for detecting the presence of soil in the same body as the support frame portion 20, by controlling the electrohydraulic cylinder device so that only the lower sensor of these sensors senses the soil. It is preferable that the main part of the root cutting blade 42 always moves a certain depth in the ground during harvesting.
[0025]
Next, an example of use in the case where leaf vegetables such as spinach and Japanese mustard are harvested with the harvesting machine of the present embodiment configured as described above will be described.
In running on the road or in the field until harvesting is started, the electrohydraulic cylinder device 45 is extended to swing the support frame 20 and the part integrated therewith upward about the horizontal axis g1. The weeding unit 15, the root cutting blade 42, the conveyance start end of the holding conveyance means 16, etc. are raised by an appropriate distance from the crawler type traveling device 3, and the leg portions 39 and the support wheels 40 of the support wheel means 36 are stored. After reaching the state, the grip portion of the steering handle 8 is gripped, and the rotation of the engine 5 is transmitted to the crawler 12 of the crawler type traveling device 3.
[0026]
As a result, the aircraft can travel smoothly without touching the ground or the like, and can travel without any trouble even in a narrow passage.
If necessary, the support wheel means 36 may be returned to the use state and run with the support wheel 40 grounded.
When changing the advancing direction during traveling, the steering handle 8 is pushed downward to change the longitudinal tilt of the entire aircraft.
As a result, the entire body changes its posture so that the front end of the crawler type traveling device 3 is lifted with the rear end 12a of the ground contact portion of the crawler 12 as a fulcrum.
Under this state, the steering handle 8 is swung to the left and right to change the body to a desired direction, and then the pressing force applied to the steering handle 8 is removed.
As a result, the aircraft returns to the state where the entire grounding portion of the crawler 12 is grounded by its own weight, and proceeds to the direction of the new aircraft.
[0027]
Handling at the time of harvesting is performed as follows, for example.
That is, as shown in FIG. 1, by aligning the machine body along the row m of vegetation vegetables to be harvested, the nipping and conveying path d1 of the forward and backward conveying unit 21a of the nipping and conveying means 16 is matched with the row m. As shown in FIG. 4, an appropriate number of containers n1 and n2 are placed on the collection table 35, the handle 35a of the collection table 35 and the operating member s are held by hand, and the lock means k is operated to bring the collection table 35 to the rearmost position. After being moved and locked, the rotation of the engine 5 is transmitted to the crawler traveling device 3 and the vegetable processing unit 2 to advance the machine body, and the electrohydraulic cylinder device 45 is appropriately shortened.
As a result, the root cutting blade 42 enters the soil by a distance corresponding to the operation of the electrohydraulic cylinder device 45 due to the weight of the machine body and the reaction force from the soil acting on the root cutting blade 42.
During the operation of the vegetable processing unit 2, the root cutting blade 42 is driven by the crank mechanism unit 43 and vibrates around the lateral axis g4. This vibration promotes the entry of the root cutting blade 42 into the soil.
[0028]
During the course of the aircraft, the weeding unit 15 acts to untangling the row of vegetables v being harvested and the row of vegetables v adjacent to the left and right.
At this time, the weed plates 33a and 33b of the weed portion 15 are in contact with the upper part of the vegetable v such as spinach on a relatively wide surface to suppress the damage.
[0029]
As shown in FIG. 1, when one vegetable v1 in the vegetable row m reaches the conveyance start end of the nipping and conveying device 16, the pair of left and right star wheels 29a and 29a sandwich the upper portion of the vegetable v1 between the front and rear conveying unit 21a. On the other hand, the main part of the root cutting blade 42 cuts the root part of the vegetable v1 while swinging back and forth.
At this time, the cutting depth by the root cutting blade 42 is preferably about several cm (about 2 to 3 cm) from the ground.
[0030]
The upper part of the vegetable v that is nipped and conveyed by the front and rear conveying unit 21a is gradually raised along with the inclination, and finally pulled out from the ground.
At this time, the transport belts 26 and 27 of the sandwiching and transporting means 16 are sponge-like and sandwich the vegetables v softly. On the other hand, the root portion is cut, so that a large pulling force does not act when pulling, Damage to the upper part of the vegetable v is suppressed.
[0031]
The upper part of the extracted vegetable v is conveyed to the downstream side of the nipping and conveying path d1 at about the aircraft traveling speed, and finally reaches the vicinity of the triangular space b.
Here, the star wheel 31 of the feed force applying means 30 sandwiches the upper portion of the vegetable v with the guide bar 32 and applies the feed force thereto.
Therefore, even in the upper part of the vegetable v that is located in the triangular space b and does not receive a sufficient feeding force by the conveyor belts 26, 27, 28, it is reliably conveyed toward the laterally conveying section 21b without causing a conveyance delay. Will be.
[0032]
The sideways transport unit 21b transports the upper part of the vegetable v that has reached here toward the transport end via the sandwich transport path d2, and finally discharges it outward from the transport end.
Since the discharged vegetable v upper portion is imparted with conveyance resistance by the conveyance resistance imparting means at the root portion, it falls into a container n1 or n2 in a sideways posture in which the root side is directed toward the body.
This fall is repeated one after another as the harvest progresses, and the upper parts of the vegetables v are piled up in the container.
Each time this pile is appropriately enlarged, the collection stand 35 is repeatedly moved and fixed forward by an appropriate distance, whereby the front and rear containers n1 and n2 are filled with the top of the vegetables v. .
[0033]
When the amount of vegetables v conveyed on the collection table 35 increases and the aircraft tends to overturn due to the load, the support means 36 in the storage state is put into a use state as shown in FIG. The wheel 40 is held in a grounded state, and the load acting on the collection base 35 is supported by the support wheel 40.
Thereby, even if a big load is acting on the collection stand 35, the harvesting posture of the aircraft is stably maintained.
[0034]
During the harvesting, the crawler type traveling device 3 runs on the uneven ground which is loosened by the root cutting blade body 42 and pulled out from the upper part of the vegetables v. The surface pressure with respect to the surface is small and does not sink excessively in the soil, and the long ground contact surface does not cause a large forward / backward inclination of the aircraft.
[0035]
Since it is almost straight running during the harvesting, the change operation of the aircraft traveling direction during the harvesting can be finely adjusted, and it is sufficient to apply a slight left-right operating force to the steering handle 8.
In addition, the large change operation which is rarely required is performed according to the case of non-harvesting.
[0036]
At the start of the harvesting operation, the middle harvest may be performed as shown in FIG. 5. In this case, when the support wheel 40 interferes with the row of vegetables, the support wheel 42 and the leg 39 are stored. And
That is, the leg 39 is swung about 90 degrees around the horizontal axis g1 to have a horizontal posture, and the support ring 39 is turned 90 degrees about the vertical axis g2 so that the support ring means 36 has a horizontal flat shape. To be along the lower surface of the collection table 35.
As a result, the aircraft is in a state in which it is possible to carry out middle harvesting without damaging the vegetated vegetables v.
[0037]
The above embodiment can be modified as follows.
That is, the collection base 35, the front-rear guide body 38, and the base support arm member 37 are displaceable to the left f3 with respect to the overhanging portion 4a of the machine body frame 4, or the front portion of the base support arm member 37 is directed front-rear. By making it possible to bend the upper part f4 around the axis, or by combining both of them, the overhanging dimension of the collecting stand means 17 outward from the machine body is shortened.
The movable table 35 can be fixed and moved in the front-rear direction with respect to the front-rear guide body 38 by power driving means such as an electric motor.
[0038]
As shown in FIG. 6, in the lower part of the rear portion of the weed 15, instead of the root cutting blade 42 that is vibrated in the front-rear direction, the disk 5 is rotated around the vertical axis g 5 by the engine 5 or an electric motor provided separately. The root cutting blade body 42 is installed, and the root portion is cut with a saw blade-like blade formed on the outer peripheral edge of the blade body 42.
According to this, longitudinal vibration is not generated in the airframe, and a comfortable harvesting operation is possible.
[0039]
Instead of the engine 5, an electric motor is provided. According to this, no exhaust gas is generated, and the work in the house h as shown in FIG. 5 becomes comfortable.
The processing unit height changing means 19 can be configured to perform a necessary changing operation through a screw / nut mechanism or the like operated by a manual operation force.
[0040]
Furthermore, the left and right arrangements of the respective parts may be of the reverse-handed specification so as to have a symmetrical relationship with that of the above embodiment.
[0041]

In addition, the crawler type traveling device can obtain suitable traveling performance even if the overall height is low, which contributes effectively to reducing the height of the fuselage, and the contact surface pressure is applied to the traveling wheel. In order to reduce the size, it is possible to prevent the vegetable from sinking excessively into the soil even when traveling on the ground where the vegetables have been pulled out and softened.
In addition, the crawler traveling device is in the state of being most distant from the row of unharvested vegetables adjacent to the left and right of the currently harvested vegetable row during the middle harvesting, and this is the width of the crawler traveling device. It makes it possible to form a large.
In this case, the crawler traveling device travels on the harvested trace, but the surface pressure of the ground contact portion with respect to the ground at the time of traveling can be reduced, and the settlement into the soil can be suppressed .
