PROBLEM TO BE SOLVED: To easily transfer a seedling box by switching a preliminary seedling placing table to a rail state that seedling box placing faces of a plurality of the preliminary seedling placing tables form a long rail-shaped transfer face in one direction by turning a link, in the preliminary seedling placing table such as a sulky rice transplanter.SOLUTION: A preliminary seedling placing table is constituted of an upper-stage preliminary seedling placing table 12d, a middle-stage preliminary seedling placing table 12c and a lower-stage preliminary seedling placing table 12b, the upper-stage preliminary seedling placing table 12d, and the middle-stage preliminary seedling placing table 12c are connected to each other by fore-and-aft links 26, the middle-stage preliminary seedling placing table 12c and the lower-stage preliminary seedling placing table 12b are also connected to each other by the fore-and-aft links, and by the turn of the links 26, the preliminary seedling placing table can be switch to a seedling box placing state that the upper-stage preliminary seedling placing table 12d, the middle-stage preliminary seedling placing table 12c and the lower-stage preliminary seedling placing table 12b are separated from one another in a vertical direction at prescribed intervals, and a rail state that seedling box placing faces of the upper-stage preliminary seedling placing table 12d, the middle-stage preliminary seedling placing table 12c and the lower-stage preliminary seedling placing table 12b form a long rail-shaped transfer faces in one direction.COPYRIGHT: (C)2015,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
