It is prevented that it becomes damaged and cannot be used for planting work.
また、延長苗枠フレーム24の形状は、苗枠フレーム21と同一形状とすることにより、延長苗枠フレーム24の側方に更に延長苗台T1を装着することができるので、使用する苗トレイの数に合わせて延長苗台T1の数を変更し、苗トレイの補充作業の回数の軽減を図ることができる。 Moreover, since the extended seedling frame 24 has the same shape as the seedling frame frame 21, the extended seedling frame T1 can be attached to the side of the extended seedling frame frame 24. The number of extension seedling stands T1 can be changed in accordance with the number, and the number of seedling tray replenishment operations can be reduced.
また、延長苗台T1と下部取付部材23aとの間に回動支持部26を設けて延長苗台T1を走行車体側に跳ね上げ可能に軸支することにより、輸送時や収納時に延長苗台T1を取り外す作業が不要となるので、作業能率が向上すると共に、作業者の労力が軽減される。 In addition, a rotation support portion 26 is provided between the extended seedling base T1 and the lower mounting member 23a, and the extended seedling base T1 is pivotally supported so as to be able to be flipped up to the traveling vehicle body side, so that the extended seedling base can be transported or stored. Since the work of removing T1 becomes unnecessary, the work efficiency is improved and the labor of the operator is reduced.
