PROBLEM TO BE SOLVED: To provide an empty cell tray-recovering mechanism of a seedling transplanter, which is free from a necessity (troublesomeness) that an operator sitting on a driver seat and performing travel operations separates from the driver seat, moves to the lower surface side of a seedling-supplying means on which an empty tray is carried out, and individually recovers the empty cell tray.SOLUTION: The empty cell tray-recovering mechanism of the seedling transplanter, in which a transplantation portion is connected to the rear side of a travel portion a cell tray on which cells for receiving cell seedlings are longitudinally and latitudinally orderly formed can be loaded on a seedling-supplying means disposed in the transplantation portion an empty cell tray from which all of cell seedlings are taken out is carried out and recovered from the lower end portion of the seedling-supplying means to the lower surface side of the seedling-supplying means in a returning state, is characterized in that the empty cell tray carried out on the lower surface side of the seedling-supplying means is carried out to a position near to the drivers seat disposed in the travel portion.COPYRIGHT: (C)2013,JPO&INPIT【課題】運転席に着座して走行操作している作業者が運転席から離座して空のセルトレイが搬出されている苗供給手段の下面側まで移動して、空のセルトレイを一枚ずつ回収する必要性がない(煩雑さがない)ようにすること。【解決手段】走行部の後方に移植部を連結し、移植部に配設した苗供給手段上にセル苗を収容するセルを縦横に整然と形成したセルトレイを載置可能とし、セル苗が全て取り出された空のセルトレイは苗供給手段の下端部から折り返し状に苗供給手段の下面側に搬出して回収されるようにした。そして、苗供給手段の下面側に搬出された空のセルトレイは、走行部に配設した運転席の近傍位置まで搬出されるようにした。【選択図】図8
