PROBLEM TO BE SOLVED: To provide a seedling transplanter having a line-drawing marker 1 capable of always drawing marks on a field as guides for going straight, regardless of whether the field is deep or shallow.SOLUTION: The seedling transplanter includes a seedling tank 20 for carrying seedlings for a plurality of ridges at the rear of a vehicle body 5, a planting device 7, and a link mechanism 6 for raising and lowering the seedling tank. A side marker 57 that serves as a guide for going straight while located above the seedlings planted on a field, a line-drawing marker 1 for drawing lines that serve as guides for going straight by making contact with a field surface, and a partial ridge clutch lever for turning on and off a partial ridge clutch that turns on and off the drive of a certain planting device 7 are provided. The seedling transplanter also includes an automatic side marker adjusting mechanism for automatically adjusting the vertical position of the side marker 57 according to the depth of the field, and an automatic line-drawing marker position changer for automatically changing the horizontal position of the line-drawing marker 1 as the partial ridge clutch lever is operated.COPYRIGHT: (C)2013,JPO&INPIT【課題】圃場の浅い深いに拘わらず、常に直進の指標となるマークを圃場に引くことができる線引きマーカ1を備えた苗移植機を提供すること。【解決手段】車体5の後側に複数条分の苗を積載する苗タンク20と植付装置7と苗タンク昇降用のリンク機構6を備え、圃場に植え付けた苗の上方に位置して直進の目安とするサイドマーカ57と圃場面に接触して直進の目安となる線を引く線引きマーカ1と任意の植付装置7の駆動を入切する部分条クラッチの入切を行う部分条クラッチレバーを設け、 圃場の深浅に合わせてサイドマーカ57の上下位置を自動調節するサイドマーカ自動調節機構と部分条クラッチレバーの操作に合わせて線引きマーカ1の左右位置が自動的に変更される線引きマーカ位置自動変更装置を備えた苗移植機である。【選択図】図1
