PROBLEM TO BE SOLVED: To provide a seedling transplanter which can be switched into "extende state" or "stored state" without spending the labor of a worker and can improve the efficiency of work even during a switching work without interrupting any other work.SOLUTION: A seedling transplanter comprises a plurality of preliminary seedling mounting members 38a, 38b, 38c for mounting preliminary seedlings onto a traveling vehicle, link mechanisms 39a, 39b, 39c for connecting the plurality of preliminary seedling mounting members 38a, 38b, 38c so as to rotate the plurality of preliminary seedling mounting members 38a, 38b, 38c freely, and two preliminary seedling frames 38 which can be switched into "extended state" where the plurality of the preliminary seedling mounting members 38a, 38b, 38c are aligned in a front and forward direction or " stored state" where they are aligned vertically by an operation of the link mechanisms 39a, 39b, 39c. The two preliminary seedling frames 38 are provided with a switching device 300 for switching between the extended state and the stored state of the link mechanisms 39a, 39b, 39c, and configured such that when the switching device 300 is operated, the two preliminary seedling frames 38 are interlockingly switched between the extended state and the stored state.COPYRIGHT: (C)2014,JPO&INPIT【課題】作業者が労力を費やすことなく「展開状態」と「収納状態」との切り替えを行うことができ、切替作業中であっても他の作業を中断せずにすみ、作業能率を向上することが可能な苗移植機を提供する。【解決手段】走行車体に予備の苗を積載する複数の予備苗載部材38a,38b,38cと、複数の予備苗載部材38a,38b,38cを回動自在に連結するリンク機構39a,39b,39cを備え、リンク機構39a,39b,39cを操作すると複数の予備苗載部材38a,38b,38cが前後に並ぶ展開状態と、上下に並ぶ収納状態に切替可能な予備苗枠38を2つ設けた苗移植機において、2つの予備苗枠38にリンク機構39a,39b,39cを展開状態と収納状態に切り替える切替装置300を設け、切替装置300を作動させると2つの予備苗枠38が連動して展開状態と収納状態に切り替わる構成とした。【選択図】 図9
