PROBLEM TO BE SOLVED: To provide a seedling transplanter enabling a proper amount (count) of seedlings to be fed to a seedling-unloading port in high accuracy and the seedlings to be planted in a proper amount in a farm irrespective of operating conditions, etc.SOLUTION: The seedling transplanter includes: a seedling stand 80 at a seedling-unloading port 78 provided on a seedling-receiving frame 81 for receiving seedlings ends, functioning to feed seedlings through transverse movement along the seedling-receiving frame 81 thereon apparatuses 135 functioning to vary the conveying amounts of seedlings on the seedling stand 80, on the transverse movement ends of the seedling stand 80, onto the seedling-receiving frame 81 side by a seedling conveyor 79 and a seedling-conveying level controller 200 enabling the amount of seedlings taken by a seedling planting apparatus 37 to be varied by varying the position of the seedling-unloading port 78 by a seedling-taking level control lever 201, and varying seedling-conveying levels by the seedling conveyor 79 in conjunctive operation with seedling-taking levels by the lever 201 so that the increase in seedling-conveying levels relative to the increase in seedling-taking levels become less as the seedling-taking levels increase.COPYRIGHT: (C)2011,JPO&INPIT【課題】作業条件等に拘らず、苗取出口へ適正な苗量(苗本数)を精度良く供給し、適正な苗量で圃場に苗を植え付けることができるようにした苗移植機の提供。【解決手段】苗の端部を受ける苗受枠81にある苗取出口78に、苗受枠81の上側で該苗受枠81に沿って左右移動して苗を供給する苗載台80を設け、該苗載台80の左右移動端で該苗載台80上の苗を苗受枠81側へ苗移送装置79により移送する量を変更する苗移送量変更装置135と、苗取り量調節レバー201により苗取出口78の位置を変更することにより苗植付装置37が取る苗の量を変更可能とし、該レバー201による苗取り量の変更に連動して苗移送装置79による苗の移送量が変更され、苗取り量が多いほど苗取り量の増加に対する苗の移送量の増加が小さくなるように変更される苗移送量変更制御装置200を設けた苗移植機である。【選択図】図3
