PROBLEM TO BE SOLVED: To enable to switch between the extended seedling vessel-loading position and the standing storing position of reserve seedling-loading shelves by a simple operation in a construction in which a plurality of the reserve seedling-loading shelves are vertically installed to shelf support props of the rice transplanter.SOLUTION: The reserve seedling-loading shelves of the rice transplanter are constructed so that the reserve seedling-loading shelves 12 turn between the seedling vessel-loading position where the reserve seedling-loading shelves 12 extend outward and the stored position where the shelves 12 are along the shelf support props 14 by installing an interlocking rod 25 and moving the interlocking rod 25 upward and downward and by standing the shelf support props 14 of the shelves 12 to a travelling machine body, wherein the interlocking rod 25 pivottingly supports the base of the shelf support props 14 to extend outward the reserve seedling-loading shelves 12, and simultaneously protrudes action pieces 24 toward the inside and vertically connects the action pieces 24 of the reserve seedling-loading shelves 12.COPYRIGHT: (C)2010,JPO&INPIT【課題】本発明では、田植機の棚支柱に予備苗載せ棚を上下方向複数設けた構成で、予備苗載せ棚の張り出し苗容器載置位置と起立収納位置への切換えを簡単な操作で行えるようにすることが課題である。【解決手段】走行機体に立設した棚支柱14に予備苗載せ棚12を外側方へ張り出すべくその基部を棚支柱14に枢支すると共に基部から作用片24を内側に突出し、各予備苗載せ棚12の作用片24を縦に連結する連動杆25を設け、該連動杆25を上下動することで予備苗載せ棚12が側方へ張り出す苗容器載置位置と棚支柱14に沿わせた収納位置の間で回動すべくして田植機の予備苗載せ棚を構成した。【選択図】図3
