PROBLEM TO BE SOLVED: To provide a seedling transplanting machine in which a preceding seedling box is made to reliably follow the next seedling box.SOLUTION: A seedling transplanting machine includes: a seedling loading platform 7 for sequentially conveying multiple seedling boxes N1, N2 to a seedling extruding apparatus 6 positioned downward and a feeder 7a for moving the seedling box N1 of the most downstream in the seedling loading platform 7 to the seedling extruding apparatus side every predetermined pitch. Further, the seedling transplanting machine includes an auxiliary feeder including: a rotating shaft 35 with a wheel center extending to the widthwise direction of the seedling loading platform 7 and rotatably supported to a frame of the seedling loading platform 7 a seedling box feed roller 36 provided in the rotating shaft 35 and arranged so that the peripheral surface may come in abutment with the back side of the next seedling box N2 of the seedling box N1 of the most downstream drive means 37 for rotationally driving the rotating shaft 35 so as to move the next seedling box N2 to the seedling box extrusion device side every predetermined pitch in synchronism with the movement of the seedling box N1 of the most downstream and a first one-way clutch 38 provided between the drive means 37 and the rotating shaft 35 and transmitting only the driving force in the rotational drive direction of the drive means 37 to the rotating shaft 35.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2018,JPO&INPIT【課題】 先行する苗箱に次の苗箱を確実に追従させる。【解決手段】 苗移植機は、複数の苗箱N1,N2を順次下方に位置する苗押出装置6まで搬送する苗載台7と、該苗載台7における最下流の苗箱N1を所定ピッチごとに前記苗押出装置側へ移動させる送り装置7aとを備える。さらに、苗載台7の幅方向に軸心が延びるとともに、回転自在に該苗載台7のフレームに支持された回転軸35と、回転軸35に設けられ、最下流の苗箱N1の次の苗箱N2の裏面対して周面が当接するように配設されている苗箱送りローラ36と、次の苗箱N2を最下流の苗箱N1の移動に同期させて前記所定ピッチごとに前記苗箱押出装置側へ移動させるように、回転軸35を回転駆動する駆動手段37と、駆動手段37及び回転軸35の間に設けられ、駆動手段37の回転駆動方向の駆動力のみを回転軸35に伝達する第一ワンウェイクラッチ38とを備える補助送り装置を備えている。【選択図】 図2
