PROBLEM TO BE SOLVED: To enable the transplanting depth of a seedling by a seedling transplanter to be uniform without lifting or lowering the seedling-transplanting device even if right and left land-leveling rotors level a disordered muddy soil surface while being lifted and lowered.SOLUTION: The seedling transplanter equipped with the seedling-transplanting device attached to the rear side of a traveling car body is constituted as follows. The land-leveling rotor of the seedling transplanter is constituted by hanging an attaching rod 67a of a land-leveling rotor-supporting frame 68 for axially supporting right and left land-leveling rotors 27a between the traveling car body and the seedling-transplanting device with a mechanism A linearly sliding in the rearward fallen upper direction of a bracket 85 installed in a supporting frame body of the seedling-transplanting device.COPYRIGHT: (C)2010,JPO&INPIT【課題】本発明では、左右整地ロータが乱れた泥土面を昇降しながら整地しても苗植付装置が昇降すること無く苗植付装置の苗植え付け深さが均等になるようにすることが課題である。【解決手段】走行車体の後側に苗植付装置を装着した苗植機において、走行車体と苗植付装置の間で、左右整地ロータ27aを軸支する整地ロータ支持フレーム68の取付杆67aを、苗植付装置の支持枠体に設けるブラケット85の後倒れ上方への直線的なスライド機構Aで吊下げて苗植機の整地ロータを構成した。【選択図】図7
