PROBLEM TO BE SOLVED: To provide a seedling transplanter for inserting a planting tool accommodating a seedling into a farm field and opening the lower portion at a bottom dead point or the vicinity and for lifting while leaving the seedling in the farm field, wherein the leaf apex of the seedling left in the farm field is clamped but not pulled out by the closed planting tool, and wherein the planting tool is closed at a timing as early as possible till the planting tool reaches a top dead center so that the planting cycle of the planting tool may be accelerated to improve the work efficiency.SOLUTION: A transplanter, in which a planting tool accommodating a planting seedling is lowered and inserted in a farm field and is opened to plant the seedling in the farm field and then rise, is characterized in that the timing for closing the planting tool is made variable in a closing mechanism 135.SELECTED DRAWING: Figure 12COPYRIGHT: (C)2016,JPO&INPIT【課題】本発明は、苗を収容した植付具を圃場に差し込んで下死点もしくはその近傍で下部を開いて苗を圃場に残して上昇する苗移植機において、圃場に残した苗の葉先を閉じる植付具で挟み込んで引き抜かないようにすると共に植付具が上死点に達するまでの出来るだけ早いタイミングで閉じるようにすることで植付具の植付サイクルを早くして作業効率を良くすることを課題とする。【解決手段】植付苗を収容した植付具が降下して圃場に差し込んだ後に開口して植付苗を圃場に植え付け上昇する移植機において、閉口調整機構135で植付具の閉じるタイミングを変更可能にしたことを特徴とする移植機とする。【選択図】図12
