PROBLEM TO BE SOLVED: To provide a seedling transplanter which has a constitution hardly allowing mud and water adhered on a line drawing marker during contact with a field surface to scatter when the line drawing marker is lifted.SOLUTION: A seedling planting machine includes a line drawing device 3 drawing a line, which serves as a target in a next process seedling planting travel, such that the line drawing device can be switched so as to be taken in/out between a line drawing position A on a side part soil surface and a storage position B on a side edge part of a seedling planting device 2. In the line drawing device 3, a line drawing marker 7 is constituted by arranging at a tip part of a marker arm 4, which rotates so as to be taken in/out between the line drawing position A and storage position B, a rotatable rotation body 6 arranged with lags 5 rotating and contacting the soil surface in an outer periphery. A mud prevention cover 8 is arranged which covers an upper side part of the line drawing position A of the rotation body 6 and prevents mud from scattering to the seedling planting device 2 side at the storage position B. A mud prevention fender 9 is arranged which faces an inner side of the storage position B of the line drawing marker 7 on left/right both sides of the seedling planting device 2 and prevents mud from scattering to the seedling planting device side.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2016,JPO&INPIT【課題】圃場面に接触した際に線引マーカに付着した泥土や水が、線引マーカの上昇時に飛散しにくい構成の苗移植機を提供する。【解決手段】次行程苗植走行の視標となる線引きを行う線引装置3を、側部土壌面の線引位置Aと、苗植付装置2の側端部の収納位置Bとに出し入れ切替可能に設ける苗植機において、線引装置3は、線引位置Aと収納位置Bとに出入回動のマーカアーム4の先端部に、土壌面に接触回動するラグ5を外周部に配置した回転体6を回転自在に設けて線引マーカ7を構成し、この回転体6の線引位置Aの上側部を覆うと共に、収納位置Bでは苗植付装置2側への泥土飛散を防止する防泥カバー8を設け、苗植付装置2の左右両側部で、前記線引マーカ7の収納位置Bの内側に対向して、苗植付装置側への泥土飛散を防止する防泥フェンダ9を設けて構成する。【選択図】 図3
