PROBLEM TO BE SOLVED: To provide a seedling transplanter whose seedling planting element of the seedling planting device does not stop at places other than the regular position.SOLUTION: A seedling planting part 7 is so formed that, when a working vehicle 1 retreats, a seedling planting device 14 is stopped and a seedling planting part 7 is automatically raised, when re-advancing, the seedling planting part 7 is raised as it is and when the advancing speed reaches at a certain speed, a seedling planting element 11 of the seedling planting device 14 is returned and stopped to be in a state capable of planting seedlings, that is, a phase of the starting position. Thus, when planting seedlings by the seedling planting part 7 with the working vehicle 1 advancing, as the seedling planting element 11 is positioned at the starting position, so planting of seedlings can be performed by lowering the seedling planting part 7 on the field.COPYRIGHT: (C)2009,JPO&INPIT【課題】苗植付装置の苗植付具が正規の位置以外の位置で停止することがない苗移植機を提供すること。【解決手段】苗植付部7を作業車両1が後進する場合に苗植付装置14を停止させて苗植付部7を自動的に上昇させ、再度前進する場合には苗植付部7を上昇させたままで、前進速度が一定速度に達すると、苗植付装置14の苗植付具11を苗植え付け可能な状態、すなわちスタート位置の位相に戻して停止させる。こうして、再び作業車両1を前進させながら苗植付部7により苗の植え付けを行う場合には苗植付具11がスタート位置にあるので、苗植付部7を圃場上に下降させると苗の植え付けが可能になる。【選択図】図4
