PROBLEM TO BE SOLVED: To provide a reserve seedling stand for a riding rice transplanting machine, etc., made as capable of easily conveying seedling boxes by turning links for switching the seedling box-loading surfaces of the plurality of reserve seedling stands to a rail state for forming a one directional long rail like conveying surface.SOLUTION: The reserve seedling stand is constituted by an upper stage reserve seedling stand 12d, a middle stage reserve seedling stand 12c and a lower stage reserve seedling stand 12b, and the upper stage reserve seedling stand 12d with the middle stage reserve seedling stand 12c, and the middle stage reserve seedling stand 12c with the lower stage reserve seedling stand 12b are linked by front and rear links 26. Also the stand is constituted that by the turning of the links 26, the state of the stand can be switched between a seedling box-loaded state where the upper stage reserve seedling stand 12d, middle stage reserve seedling stand 12c and lower stage reserve seedling stand 12b are separated by a prescribed distance in vertical direction and as the rail state where the seedling box-loading surfaces of the upper stage reserve seedling stand 12d, middle stage reserve seedling stand 12c and lower stage reserve seedling stand 12b form the one directional long rail like conveying surface.COPYRIGHT: (C)2013,JPO&INPIT【課題】 本発明は、乗用田植機等の予備苗載せ台において、リンクを回動させて複数の予備苗載せ台の苗箱載置面が一方向に長いレール状の搬送面を形成するレール状態に切り替えることにより、苗箱を楽に搬送することができるようにするものである。【解決手段】 上段予備苗載せ台12dと中段予備苗載せ台12cと下段予備苗載せ台12bで構成し、上段予備苗載せ台12dと中段予備苗載せ台12c並びに中段予備苗載せ台12cと下段予備苗載せ台12bを前後のリンク26で連結し、リンク26の回動により、上段予備苗載せ台12dと中段予備苗載せ台12cと下段予備苗載せ台12bが上下方向に所定間隔離れた苗箱載置状態と、上段予備苗載せ台12dと中段予備苗載せ台12cと下段予備苗載せ台12bの苗箱載置面が一方向に長いレール状の搬送面を形成するレール状態に切り替え可能に構成した。【選択図】 図4
