Description

【０００１】
【産業上の利用分野】
この発明は、苗植機の補助苗棚枠に関し、苗植装置に補給するための苗箱、及びポット苗供給後の空箱を収容するものである。
【０００２】
【従来の技術、および発明が解決しようとする課題】
補助苗箱を苗植装置に供給すると、ポット苗の取出された空箱が繰出されるが、従来の補助苗棚枠では、空箱を他の苗箱の邪魔にならないように積重ねて収容して空箱処理を行うことが困難であった。
【０００３】
【課題を解決するための手段】
この発明は、苗箱Ｃから育苗されたポット苗Ａを取出して植付ける苗植装置３を車体１に連結すると共に、車体１に苗箱Ｃを載せることができる苗棚を上下多段で且つ前後に備える補助苗棚枠２を配置した苗植機において、補助苗棚枠２の一部の上下複数段分の苗棚に亘って高く空箱Ｂが滑り落ちないように受枠２７を設けて、前記上下複数段分の苗棚を苗植装置３によりポット苗Ａが取出された空箱Ｂを多数積重状態で収容可能な空箱収容棚４に構成したことを特徴とする苗植機の構成とする。
【０００４】
【作用、および発明の効果】
苗植作業時には、予め補助苗棚枠２の上下多段で且つ前後に配置した苗棚にポット苗Ａが育苗された苗箱Ｃを積載しておき、苗植に伴って苗植装置３の苗量が減少すると、この補助苗棚枠２に積載していた苗箱Ｃを取出して苗植装置３へ補給しながら、苗植作業を継続する。苗植装置３に供給された苗箱は、ポット苗Ａの取出が行われ、苗植付が行われるが、このポット苗Ａの取出された空箱Ｂが繰出される。
【０００５】
このように苗植装置３から取出される空箱Ｂは、補助苗棚枠２において苗箱Ｃが取出された空箱収容棚４に積重ねて受枠２７により滑り落ちないようにして収容する。このため、補助苗棚枠２の一部の上下複数段分の苗棚を空箱収容棚４として、他の苗箱の邪魔にならないように積重ね収容し、構成を簡単にして、積重空箱処理を容易に行いうる。
【０００６】
【実施例】
車体１は、前部のステアリングポスト５上のハンドル６によって操向自在の前車輪７と、後車輪８とを有して、操縦席９の下側に搭載するエンジンの駆動によって回転走行しうる。ステアリングポスト５の左右両側部から操縦席９の両側部に亘ってステップフロア１０を設けている。
【０００７】
苗植装置３は、前記車体１の後方部に平行リンク機構１１を介して昇降自在に連結し、車体１後部とこの平行リンク機構１１との間に設ける油圧による昇降シリンダ−１２の伸縮によって昇降することができる。苗植機体１３は、下方に土壌面に接地滑走するフロ−ト１４を有し、上方には、ポット苗Ａを収容した苗箱Ｃを上下二段に収容して後側下方の苗繰出装置１５へ供給する苗箱供給台１６と、この苗繰出装置１５へ供給されたポット苗箱を一ポット苗列毎下方へ繰出しながら、この苗箱Ｃからポット苗を押出す苗押出装置１７、この苗出装置１７から押出された苗を保持して、苗送ベルト１８上に載せ替える苗載替装置１９、及び、この苗送ベルト１８によって送り出されるポット苗Ａを土壌面へ植付ける苗植付装置２０等を多条植形態として設けると共に、該各苗箱供給台１６の下方には、これら苗繰出装置１５からＵ字状に形成された苗通路２１に沿って繰出されてくる空箱Ｂを受けて収容する空箱受枠２２を設け、各段の苗箱供給台１６に苗箱Ｃを載せておくことにより、一箱毎に連続して繰出装置１５により箱通路２１へ繰出され、この箱通路２１を繰出される間に押出装置１７によって一ポット苗列毎に苗箱Ｃから押出され、ポット苗Ａは、苗載装置１９によって苗送ベルト１８へ苗載せ替えられて、苗植付装置２０により植付られる。このポット苗Ａの押出を受けた空箱Ｂは箱通路２１から空箱受枠２２へ繰出されて積載される。
【０００８】
車体１前部の左右両側方には、補助苗棚枠２がフロントアクスルハウジング３２上の支持ア−ム２３によって内向、外向に方向切替可能にして支持される。補助苗棚枠２は、パイプ材乃至丸棒材によって多段の枠組構成とし、上端側を外側に位置するように傾斜させて苗箱Ｃの出入を行い易くし、各段には苗箱Ｃの底面を支持する受板２４を外側に向けて下り傾斜させて、苗箱Ｃ支持の安定化を図り、この受板２４の中央部には、苗箱Ｃ底面の溝部を嵌合させて苗箱Ｃの横移動を規制するリブ２５を形成し、又、傾斜下端には苗箱Ｃの下端縁を受ける苗箱ストッパ−２６を形成し、左右補助苗棚枠２共にこの受板２４が前後三等配に設けられる。
【０００９】
このような左右の補助苗棚枠２の後端部、即ち苗植装置３及び操縦席９に近い部分に空箱収容棚４を設けて、空箱Ｂを多数枚積重ねて収容しうる。この空箱収容棚４は、枚段分の苗棚高さ相当分に亘って、空箱Ｂ相互が上下に一部嵌合する状態で積重して、収容しうるもので、傾斜下端側へ滑り落ちないように補助苗棚枠２に受枠２７を設けている。従って、この受枠２７によって形成される空箱収容棚４の下端面には、前記受板２４が設けられて、苗箱Ｃを載せることができるが、この上側の中間の位置には、前記受板はもとより、この受板を支持する棚桟等は形成されず、空箱Ｂを直接積重しうる構成である。
【００１０】
なお、空箱収容棚４は、補助苗棚枠２の苗棚二段分に構成したが、空箱Ｂ数に応じて三段以上に亘って高く構成するもよい。また、この空箱収容枠に空箱を収容しないときに苗箱を載置できるようになっている。
２８は操縦席９の後側に設ける施肥装置で、苗植付装置２０による苗植付位置近くの土壌面に施肥するためのものである。
【００１１】
苗箱Ｃは、合成樹脂製の可撓性材からなり、縦、横方向に整列した適宜深さ及び口径のポット２９を形成し、各ポット２９内に床材を充填して播種育苗してポット苗Ａを得る。この苗箱Ｃの各ポット２９の底部には押出孔３０を形成し、この押出孔３０から前記押出装置１７における押出ピンを底側から挿通してポット苗Ａを押出すものである。又、苗箱幅の中央部において縦方向に並ぶポット２９列間の底面の間隔３１は他の間隔よりも若干広く形成されていて、この間隔３１を前記受板２４のリブ２５に嵌合させて案内保持することができる。
【００１２】
補助苗棚枠２を前方乃至外側方へ回動させて、各苗棚の受板２４上に苗箱Ｃを載せる。苗箱Ｃを収容したあと補助苗棚枠２を回動させて内側へ向ける。又、苗箱供給台１６にも直接苗箱Ｃを供給する。苗植作業では、苗箱供給台１６から押出装置１７へ繰出される苗箱Ｃでは、この押出装置の押出ピンによって各ポット苗Ａが押出される。ポット苗Ａの押出された空箱Ｂは箱通路２１から空箱受枠２２へ送り出されて積載される。この苗箱供給台１６の苗箱Ｃがなくなると、補助苗棚枠２の補助苗箱Ｃを取出して苗箱供給台１６に補給する。このとき空箱収容棚４に収容している苗箱Ｃから補給するとよい。
【００１３】
空箱受枠２２に空箱Ｂが積載されると、この空箱Ｂを取出して前記苗箱Ｃの取出された補助苗棚枠２の空箱収容棚４内に供給されて積重ねられる。このとき各上下の空箱Ｂ相互間を嵌合させた状態で重合させれば、多くの空箱Ｂを積載できる。このような空箱Ｂの積替操作は、空箱受枠２２と空箱収容棚４とが接近した位置にあり、しかし操縦席９に近い関係位置にあるから、迅速、容易に行うことができる。
【００１４】
図４〜図８においては、前記苗箱供給台１６の詳細を示すもので、下段の苗箱供給台１６の始端部１６Ｄに対する苗箱Ｃの供給を行い易くするために、上側の苗箱供給台１６の始端部１６Ｕの中央部に切欠部３３を形成し、この上段の苗箱供給台始端部１６Ｕの底面を下段の苗箱供給台始端部１６Ｄよりも短かくして、苗箱Ｃを図４のように前上方から始端部１６Ｄへ斜めに挿込むとき、苗葉部が該上段の苗箱供給台１６の切欠部３３を通して邪魔にならないようにする。
【００１５】
上段側の苗箱供給台始端部１６Ｕの左右両側壁３４の内側には、この苗箱供給台１６の底面３５の延長面と同位の案内溝３６を形成し、この左右の案内溝３６間に亘って上段側供給の苗箱Ｃの左右両側底部の側縁３７を嵌合させて案内させる構成としている。
前記切欠部３３には、案内溝３６に代えて、図８のように、適宜間隔のくし状の受杆３８を設けて、上段側苗箱供給台始端部１６Ｕに供給する苗箱Ｃの底面を受けて案内する構成とするもよい。従って、下段側苗箱供給台の始端部１６Ｄに供給するときの苗箱Ｃの苗葉部はこのくし状の受枠３８の間隔部を通る。
【００１６】
図９〜図１１においては、前記苗箱供給台１６に供給された苗箱Ｃの作業者の手動による取出を行い易くするために、苗箱供給台１６の一側、又は左右両側壁３４部に切欠部３８を設けたもので、この切欠部３８から手を挿込むことによって、苗箱供給台１６内に供給されている苗箱Ｃを側壁３４よりも上方へ持上げて、苗箱供給台１６の途中横側から取出すことができる。
【００１７】
又、この切欠部３８に代えて、又はこの切欠部３８と共に、底面３５に押上用の底穴３９を設けて、この底穴３９から手を挿込んで、底面３５上の苗箱Ｃを押上げて取出容易にするもよい。
