PROBLEM TO BE SOLVED: To provide a seedling transplanter capable of keeping a workload low when long seedlings are charged into a seedling feeder.SOLUTION: A seedling transplanter, which is configured in such a manner as to be travelable in a farm field, includes a seedling feeder (6) which drops seedlings from each supply cup (22) in a predetermined position by an annularly-configured cup row (22a) for transferring the charged seedlings in a go-around manner, and a seedling planting device (5) which plants the dropped seedlings in the farm field. Alignment devices (60 and 81) for resupplying the seedlings in an aligned state to the seedling feeder (6) are provided. The alignment devices (60 and 81) are arranged in the inner peripheral part of the cup row (22a) in a plan view of a transplanter body so that the seedlings can be resupplied to a position immediately close to a charging destination.COPYRIGHT: (C)2014,JPO&INPIT【課題】丈が長い苗を苗供給装置に投入する際の作業負荷を小さく抑えることができる苗移植機を提供する。【解決手段】苗移植機は、投入された苗を周回移送する環状構成のカップ列(22a)により所定位置で各供給カップ(22)から苗を投下する苗供給装置(6)と、その投下苗を圃場に植付ける苗植付装置(5)とを備えて圃場走行可能に構成され、上記苗供給装置(6)に苗を整列補給する整列装置(60,81)を設け、この整列装置(60,81)を機体平面視で上記カップ列(22a)の内周部に配置することにより、投入先の直近位置への苗補給を可能としたものである。【選択図】図11
