PROBLEM TO BE SOLVED: To provide a seedling transplanter having a seedling planting part enabling seedlings to be easily and automatically planted even in a farm e.g. in the vicinity of its entrance/exit.SOLUTION: The seedling transplanter is such that a levee-overriding arm 53 to be gripped by a relevant operator by hand e.g. when going out of a farm is set in the front of the machine body 1 e.g. when the operator leaves from the farm, a seedling planting part 3 is raised by a defined height in coincidence with the revolutions of the rear wheel 7 measured by a transmission shaft revolution sensor 54 when the machine body 1 is inclined at a defined angle or greater therefore, as the machine body 1 can be got out of the farm while planting seedlings near the entrance/exit of the farm, there is no need of manually planting seedlings by the operators handwork after the machine body 1 is got out of the farm, thus mitigating the operators labor besides, by raising the seedling planting part 3 little by little, there occurs no contact of the bottom of the seedling planting part 3 with the farms surface even in the vicinity of the entrance/exit of the farm being in upward inclination stepwise, thus preventing the seedling planting part 3 from being damaged.COPYRIGHT: (C)2012,JPO&INPIT【課題】圃場出入口付近などにおける圃場内でも苗の植え付けを自動で容易に行うことができる苗植付部を備えた苗移植機を提供すること。【解決手段】 圃場から出る際等に作業者が手で掴む畦越えアーム53を機体1の前部に設け、圃場から退出するとき等、機体1が所定角度以上傾斜する際に伝動軸回転センサ54で計測される後輪7の回転数に合わせて苗植付部3を所定高さだけ上昇させることにより、圃場の出入口付近に苗を植え付けながら機体1を圃場から出すことができるので、機体1を圃場外に出した後、作業者が手作業で苗を植え付ける必要が無く、作業者の労力が軽減される。また、苗植付部3を少しずつ上昇させることにより、段階的に上り傾斜している圃場の出入口付近であっても苗植付部3の下部が圃場面に接触することが無く、苗植付部3が破損することが防止される。【選択図】図6
