PROBLEM TO BE SOLVED: To prevent the large disorder of planting postures in ridge soil with planting tines and the breakage of the intermediate portions of leaf-stem portions, because the free falling of the leaf-stem portions starts, when the tip side of the leaf-stem portion of a vine seedling 100 is separated from a guide plate with a motion of taking out a seedling, and because the leaf-stem portion first arrives the ridge upper surface, when a height distance from the seedling takeout portion to the ridge upper surface is somewhat large.SOLUTION: A seedling supply mechanism comprises a conveyance belt 21. Seedling holder portions 22 for holding the stem portions (stem end portion) of vine seedlings are disposed on the conveyance belt with a proper distance in the conveying direction. A guide plate 58 is disposed in a state facing the vine seedling-loading surface on the conveyance belt from the downward conveying process of the conveyance belt to the seedling takeout portion 21d of the lower end portion in the seedling supply mechanism. Further, an inclined guide member 71 for guiding the vine seedlings to the ridge upper surface is connectedly disposed to the guide plate 58 in the seedling takeout portion 21d.COPYRIGHT: (C)2008,JPO&INPIT【課題】苗取り出し動作に伴ってつる苗100の茎葉部の先端側が案内板から外れたとたんに、当該茎葉部は自由落下を始めることになり、苗取部から畝上面までの高さ距離がある程度大きい場合に、茎葉部側が先に畝上面に到達してしまい、植付爪による畝土への植付け姿勢が大きく乱れたり、茎葉部の中途部が折損することを防止する。【解決手段】苗供給機構は搬送ベルト21によって構成され、搬送ベルトには、その搬送方向に沿って適宜間隔にて、つる苗の茎部(茎端部)を把持する苗ホルダ部22が設けられ、苗供給機構における搬送ベルトの下降搬送行程からその下端部の苗取り部21dにわたって、搬送ベルトにおけるつる苗の載置面と適宜隔てて対面するように、案内板58が配置され、さらに、苗取り部21dにおける案内板58には、つる苗を畝上面に向けて案内する傾斜案内部材71が連設されている。【選択図】図11
