PROBLEM TO BE SOLVED: To provide a seedling transplanter provided with a reserve seedling frame capable of moving seedlings to a vicinity of a planting part behind the reserve seedling frame after receiving replenishment of seedlings from a front part of the reserve seedling frame.SOLUTION: The seedling transplanter includes a planting unit for planting seedlings to a field behind a travelling body 3, and a reserve seedling frame 5 for housing, in the front part of a machine frame, the reserve seedlings to be supplied to the planting unit. The reserve seedling frame includes a plurality of stages of receiving members 5a for receiving the reserve seedlings, and a deployment link mechanism 6 for movably supporting the receiving members, and is switchable between a multi stage arrangement in which the receiving members are vertically arranged, and a serial arrangement in which the receiving members are horizontally arranged. The deployment link mechanism 6 movably supports a receiving member 5a at a top stage in the multi stage arrangement at both ends of the front and rear of the serial arrangement.COPYRIGHT: (C)2015,JPO&INPIT【課題】予備苗枠の前方から苗補充を受けた後に、予備苗枠の後方の植付部の近傍まで苗移動が可能な予備苗枠を備えた苗移植機を提供する。【解決手段】苗移植機は、走行車体3の後側で圃場に苗を植え付ける植付部と、この植付部に供給する予備苗を機体前部に収容する予備苗枠5とを備え、この予備苗枠は、予備苗を受ける複数段の受部材5aと、これら受部材を可動支持する展開リンク機構6とを備えて上下に並ぶ多段配置と前後に並ぶ直列配置とを切替え可能に構成され、上記展開リンク機構6は、上記多段配置の最上段の受部材5aを上記直列配置の前後いずれの両端位置に可動支持するものである。【選択図】図1
