PROBLEM TO BE SOLVED: To provide a machine for inserting sweet potato seedlings, capable of planting sweet potato seedlings to grow sweet potatoes well without injuring the seedlings.SOLUTION: The machine for inserting sweet potato seedlings is designed to transport a sweet potato seedling 50 to the vicinity of a planting mechanism 7 with a seedling feeding mechanism 8, grasp a stem end part with a pair of left and right planting claws 12a and 12b to take out the seedling 50, shake the planting claws 12a and 12b in the vertical directions, thrust the planting claws 12a and 12b into the field and thereby perform planting operation, wherein the pair of the left and right planting claws 12a and 12b are composed so as to open and close with a claw opening and closing mechanism, the trajectory of the planting claws 12a and 12b in taking out the seedlings is almost perpendicularly cross the stem end part, and in planting with a dynamic trajectory, a front side low end face 31 forms an inclination that the front side is higher and the rear side is lower, and the front side low end face 31 is brought into contact with a main stem 50b to plant in a main stem 50b-laying state in which the front side is higher and the rear side is lower.COPYRIGHT: (C)2007,JPO&INPIT【課題】甘藷苗を傷めることなく、甘藷が良好に生育するように植え込む。【解決手段】甘藷苗50を苗供給機構8によって植込機構7の近傍まで搬送し、茎端部を左右一対の植込爪12a・12bで掴んで苗取を行い、該植込爪12a・12bを上下方向に揺動させ、植込爪12a・12bを圃場に突入させることで、植込み作業を行う甘藷挿苗機において、前記左右一対の植込爪12a・12bは、爪開閉機構20により開閉する構成とするとともに、植込爪12a・12bの苗取時における軌跡は、茎端部と略直交させ、動軌跡における植込時に、前側下部端面31が前高後低の傾斜を形成させ、該前側下部端面31が主茎50bに当接して、主茎50bを前高後低に寝かせた状態で植込む構成とする。【選択図】図5
