PROBLEM TO BE SOLVED: To provide a seedling transplanter capable of transplanting seedlings properly to a gutter by making the gutter as hardly collapsible in transplanting the seedlings such as onions in a field, and also aiming at the proper planting depth by stabilizing the depth of the gutter.SOLUTION: This seedling transplanter is provided by installing a traveling device 1a, a seedling-transplanting body 60 for transplanting the seedlings in the field, a ground-contacting body 28 capable of moving freely up and down and equipped with a ground-contacting surface 28a for detecting a height from the field surface to the lower surface of the machine body and in lower direction of the ground-contacting body 28, a gutter-forming body 70 capable of moving up and down as one unit with the ground-contacting body 28 and making the gutter at the position of the field for transplanting the seedlings by the seedling-transplanting body 60. Since the soil pushed away by the gutter-forming body 70, is compressed and hardened by the ground-contacting surface 28a from the upper side, the gutter becomes hardly collapsible. Also, since the gutter-forming body 70 can move up and down as one unit with the ground-contacting body 28, and the gutter-cutting depth is decided between the ground-contacting body 28 and the gutter-forming body 70, the depth of the gutter becomes stable and it is possible to aim at the proper planting depth of the seedlings.COPYRIGHT: (C)2008,JPO&INPIT【課題】圃場にねぎなどの苗を移植する際の溝を崩れにくくして、該溝へ適正に苗を植え付けることができる苗移植機を提供することである。また、溝の深さを安定させて、苗の植え付け深さの適正化が図れる苗移植機の提供である。【解決手段】走行装置1aと、苗を圃場に植え付ける苗植付け体60と、圃場面から機体下面までの高さを検出するための接地面28aを備えた上下動自在な接地体28と、該接地体28の下方に、該接地体28と一体的に上下動可能であって、前記苗植付け体60が苗を植付ける際の圃場の位置を作溝する作溝体70とを設けた。作溝体70により押し除けられる土壌は接地面28aによって上側から押し固められるため、溝が崩れにくい。また、作溝体70が接地体28と一体的に上下動可能であるため、接地体28と作溝体70との間で溝切り深さが決まり、溝の深さが安定し、苗の植付け深さの適正化が図れる。【選択図】図1
