PROBLEM TO BE SOLVED: To solve the problem that a threshing-up force is generated through a fertilization nozzle as far as to a float when the fertilization nozzle contacts obstacles, such as stones scattered in a field, and adversely affects the seedling planting accuracy.SOLUTION: A seedling transplanter 1 has a float 32 disposed so as to be capable of being lifted and lowered via an adjustment link 102 below a seedling planting device 23, and includes a both-lever mechanism 112 including the adjustment link 102 as one of oscillation joints. A fixed joint 114 of the both-lever mechanism 112 is disposed on the seedling planting device 23 side and a connection joint 116 of the both-lever mechanism 112 is disposed on the float 32 side. A first fertilization nozzle 110 for supplying a liquidity fertilizer into the ground is attached on the connection joint 116 so as to permit adjustment of its posture.SELECTED DRAWING: Figure 9COPYRIGHT: (C)2017,JPO&INPIT【課題】圃場内に散在する石等の障害物に施肥ノズルが接触した場合、施肥ノズルを介してフロートまで突き上げ力が生じて苗植付け精度に悪影響を及ぼす問題を解消する。【解決手段】本発明の苗移植機1は、苗植付装置23の下方に調節リンク102を介してフロート32を昇降動可能に配置する。調節リンク102を揺動節の1つとする両てこ機構112を備える。苗植付装置23側に両てこ機構112の固定節114を配置すると共に、フロート32側に両てこ機構112の連接節116を配置する。連接節116には、流動性肥料を地中に供給する第1の施肥ノズル110を姿勢調節可能に取り付ける。【選択図】図9
