PROBLEM TO BE SOLVED: To provide a seedling transplanter capable of improving planting accuracy of seedlings compared to the conventional art, without largely changing a degree of elevation at a seedling planting part even on an irregular field surface.SOLUTION: A seedling transplanter includes: suspension units 240L, 240R for changing a vehicle height at front and rear wheels 3L, 3R, 4L, 4R according to irregularities and the like of a field surface 70 a seedling planting part 7 arranged raisable/lowerable at a rear part of a vehicle body 2 and a planting depth adjustment mechanism composed of an electrohydraulic valve 102 and an elevation cylinder 9, for adjusting a planting depth of seedlings by raising/lowering the seedling planting part 7 according to change in float elevation angle detection means 101 for detecting an elevation angle of a center float 16C touching the field. The seedling transplanter further includes: suspension adjustment units (201L, 201R) for adjusting a degree of hardness/softness of the suspension units 240L, 240R by selecting either degree and a detection member X for detecting a condition that the suspension adjustment units 201L, 201R change a power of the suspension units 240L, 240R.COPYRIGHT: (C)2014,JPO&INPIT【課題】圃場面の凹凸があっても苗植付部の昇降度合を大きく変えないで苗の植付精度を従来以上に向上させることが出来る苗移植機を提供することである。【解決手段】前後輪3L,3R、4L,4Rを圃場面70の凹凸等に合わせて車高を変更する懸架装置240L,240Rと車体2の後部に昇降自在に配置した苗植付部7と圃場に接地する中央フロート16Cの仰角を検知するフロート仰角検知手段101の変化に合わせて苗植付部7を昇降させて苗の植付深さを調節する電磁油圧バルブ102と昇降シリンダ9からなる植付深さ調節機構を設けた苗移植機において、懸架装置240L,240Rの硬軟度合のいずれかを選択して調節する懸架調節装置(201L,201R)と該懸架調節装置201L,201Rが懸架装置240L,240Rの効力を変更する条件を検知する検知部材Xを設けたことを特徴とする苗移植機である。【選択図】図4
