PROBLEM TO BE SOLVED: To provide a seedling transplanter which can further widely adjust a change of an amount of seedling takeout and the setting of a planting depth, and is improved in operability.SOLUTION: A seedling transplanter plants seedlings taken out of a seedling takeout port 4 into a foil face which is leveled by a float 6 while reciprocally moving a seedling tank 2 which pays out and guides mat seedlings to a planter 1 side in left and right horizontal directions along a seedling takeout guide frame 5 for arranging the seedling takeout port 4 which plant-operates seedling planting claws 3 of the planter 1. The seedling takeout guide frame 5 is moved in a fore-and-aft direction, and arranged so that an amount of seedling vertical takeout by a seedling planting claw 3 is changeable to a seedling takeout region of a large-amount position from a small-amount position, a seedling takeout amount adjustment lever 8 is arranged which adjusts the amount of seedling vertical takeout, a lever guide 7 is arranged which can operate the seedling takeout guide frame 5 to an outside range exceeding a minimum amount adjustment limit position by the operation of the seedling takeout adjustment lever 8, the seedling takeout guide frame 5 is operated to the outside range B position of an adjustment region A by the operation of the seedling takeout adjustment lever 8, and the seedling takeout guide frame 5 is made to largely retreat.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2016,JPO&INPIT【課題】苗取出量の変更や植付深さの設定をより広く調整可能とすると共に、操作性を向上させた苗移植機を提供する。【解決手段】マット苗を植付装置1側へ繰出案内する苗タンク2を、植付装置1の苗植付爪3を植付作動させる苗取出口4を配置する苗取出案内枠5に沿って左右横方向へ往復移動しながら、苗取出口4から取った苗をフロート6で均された土壌面に植付ける苗植機において、苗取出案内枠5を前後方向に移動して苗植付爪3部による苗縦取量を少量位置から多量位置の苗取領域に変更可能に設けると共に、この苗縦取量を調節する苗取量調節レバー8を設け、苗取案内枠5を苗取調節レバー8の操作により、最少量調節限度位置を越えて外側域へ操作可能のレバーガイド7を設けて、苗取量調節レバー8の操作で苗取出案内枠5を調節領域Aの外側域B位置へ操作して、苗取出案内枠5を大きく後退させる構成とする。【選択図】 図3
