PROBLEM TO BE SOLVED: To provide a seeding separator designed such that even if seedling separation needles is stuck into a second row in order to separate the second row of seedlings all at once, a first row of seedlings are less likely to fall, in the seedling separator designed such that a back plate is brought into contact with a side surface of a group of seedlings such as seedlings in a paper cylinder, rows of seedling separation needles that are rotated from above the back plate and stuck into seedlings are supported on the back plate, and seedlings are held and separated in row by the back plate and a seedling separation needles stuck from above.SOLUTION: A seedling separation needle 22 is located at a rotation fulcrum on which the needle is stuck into a second row of seedlings Pa from a back plate 11. A plurality of hold needles are laterally provided, the hold needle being configured to jut out toward the back plate 11 from an abutting surface and stick in a first row of seedlings Pa. The lateral interval of the hold needles 18 differs from the interval of the seedlings Pa composing a seedling group P such that the interval of the hold needles is an integral multiple of the interval of the seedlings. Additionally, in the direction of height of seedlings, the position of the needle tip of the seedling separation needle 22 at a rotation end on the side where the seedling separation needle is stuck into the seedlings is almost the same as the position of the hold needles 18.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPO&INPIT【課題】 紙筒苗のような集合苗の側面に当板を当接させ、当板の上方から回動して苗に刺さる列状の苗分離針を当板に支架して設け、当板と上から刺しこまれた苗分離針とで苗を列状に保持、剥離する苗分離器において、二列の列状の苗を一度に剥離するために苗分離針を二列目に刺しても、一列目の苗が落下し難い苗分離器を提供する。【解決手段】 苗分離針22は、当板11から二列目の苗Paに刺さる回動支点の位置とし、当板11に当接面から突出して一列目の苗Paに刺さる保持針を横方向に複数設け、保持針18の横方向の間隔は集合苗Pを構成する苗Paの間隔の整数倍と相違する値とし、かつ苗Paの高さ方向において、苗分離針22の苗Paに刺し込む側の回動端における針先の位置と、保持針18を設ける位置を略同じとした。【選択図】図2
