PROBLEM TO BE SOLVED: To provide a seedling-transplanting machine light in weight, capable of deeply planting a sweet potato seedling, etc., into the ground in a stable manner without being affected by traveling of the machine.SOLUTION: This seedling-transplanting machine has a seedling-supplying unit 4, wherein the seedling-supplying unit 4 has a driving force-transmitting mechanism (composed of a planting part-transmission case 30 and a supply belt-transmission case 31 through a crank shaft 32) which transmits the driving force from an engine to the seedling-supplying unit 4, an endless belt 42 which has a transporting part for transporting the seedling from an upper space to an area on a farm field with the driving force-transmitting mechanism, and a planting rod 5 which presses and thrusts a part of the seedling dropped on the farm field from the endless belt 42 into the farm field. The seedling- supplying unit 4 is preferably so structured that it is inclined in the longitudinal direction of the machine.COPYRIGHT: (C)2003,JPO【課題】 機体の進行に逆らわずに、しかも軽量で、安定して甘藷苗等を土中に深く植え付けることができる苗移植機を提供すること。【解決手段】 苗移植機の苗供給装置4は、該苗供給装置4にエンジンからの駆動力を伝達する駆動力伝達機構(植付部ミッションケース30とクランク軸32を介して供給ベルト伝動ケース31)を設け、該駆動力伝達機構により上方から圃場上に向けて苗を搬送する搬送部を備えた無端帯42と、該無端帯42から圃場上に降ろされた苗の一部分を圃場内に押さえ込む植付杆5を備えている。苗供給装置4は、機体の前後方向に傾斜可能な構成を備えても良い。
