【従来の技術】
この種の従来技術としては、特開平2−303405号公報に示すように、広幅に固定された左右車輪に対して、移植装置を有する機体を左右移動するものがある。
【0003】
【従来技術の課題】
従来技術のものは、畝に対して多条の苗を植付けることができるが、一つの畝幅にのみ対応できるものであって、日本各地で畝幅が種々異なる現状では汎用性に乏しいものであった。
【0004】
【課題を解決するための手段】
この発明は、前記の従来技術のもつ課題を解決すべく、左右一対の前輪13及び後輪15を備え、左前輪13及び左後輪15を支持する左車輪支持部材11と右前輪13及び右後輪15を支持する右車輪支持部材11とを、移植装置を有する機体に対して左右方向に位置調節自在に、前輪13の近くに設けた左右方向の支持軸1aと後輪15の近くに設けた左右方向の支持軸17とでそれぞれ支持し、前記車輪支持部材11を油圧シリンダー16によって左右方向に移動可能に設けたことを特徴とする苗移植機としたものである。
【0005】
【発明の作用効果】
この発明によると、左右一対の前輪13及び後輪15により機体の姿勢を安定させた状態で走行することができ、苗の植付を安定して行える。そして、畝幅が異なるときは、油圧シリンダー16によって左又は右の車輪支持部材11を左右方向に移動することにより、移植装置を有する機体に対して少なくとも左右一方の前輪13及び後輪15を同時に位置調節することができ、左右の前後輪13,15のトレッドを容易に変更することができる。従って、種々な畝幅の畝に対応して一条植え若しくは多条植えが行なえ、従来の課題を解消することができる。しかも、車輪支持部材11を前輪13の近くに設けた左右方向の支持軸1aと後輪15の近くに設けた左右方向の支持軸17とで支持した構成としたので、車輪支持部材11を左右移動しても該車輪支持部材11の前後方向の姿勢を適正に保つことができ、前後輪13.15の向きを適正に保つことができ、所望の進行方向に機体を走行させて安定した苗の植付を行える。

【0025】
また、センサー54の畝C上面部の検出により、左右駆動前車輪13・13及び左右後輪15・15が自動的に上下動調節され苗は常に畝Cに所定の植付深さHにて植付けられる。
そして、例えば、畝Cの上面に3条の苗を植付ける場合には、先ず、左右車輪移動操作レバー60a・60bを同量だけ操作して左右車輪支持ケース11・11を左右動させて左右駆動前車輪13・13と左右後輪15・15が畝溝に位置し植付位置が畝の中央になるように車輪の位置調節をする。この状態で走行して畝の中央に苗を植付けて苗列L1とする。その後、左右車輪移動操作レバー60a・60bを操作して左右駆動前車輪13・13と左右後輪15・15が畝溝に位置し植付位置が畝の端部になるように車輪の位置調節をして、順次苗列L2とL3とを植付ける。
【0026】
尚、機体の進行を停止して苗載台28,移植装置39,開孔装置50の作動状態を確認したいときには、左右サイドクラッチレバー56・56をサイドクラッチ切り操作した状態で、スロットルレバー59にてエンジン2の回転数を上げて遠心クラッチを接続させて植付クラッチレバー57をクラッチ入操作することにより、苗載台28,移植装置39,開孔装置50のみを作動させることができる。
