A medicine feeding roller (96) serving as a medicine feeding tool having a plurality of feeding grooves (96a) at a predetermined pitch on the outer periphery, and a feeding groove of the roller (96) in contact with the outer peripheral surface of the medicine feeding roller (96) (96a) and a removal brush (97) for removing the overflowing medicine, and the seedling pot (5) is provided on the lower transport side of the medicine supply position on the delivery path (3) where the medicine feeding roller (96) supplies the medicine. A supply plate (98) is provided for supplying the medicine remaining on the nursery device (2) without entering the nursery pot (5). The transmission structure of the medicine supply device (94) will be described. When the nursery device (2) is transported, it is meshed with the transport hole (13) on the left edge toward the transport direction of the seedling device (2) and rotated. The transport interlocking sprocket (99) and the medicine feeding roller (96) rotate together and are transmitted from the medicine feeding roller (96) to the removal brush (97) through the sprockets (100, 102) and the chain (101). The In addition, the arrangement pitch of the feeding groove (96a) of the medicine feeding roller (96) is the arrangement pitch of the seedling pot (5) of the seedling raising device (2) and the conveying pitch of the seedling raising device (2) on the conveying path (3). It matches.

  As described above, the seeder is configured so as to be on the transport path (3) between the transport position of the transport tool (17) on the transport upper side and the transport position of the transport tool (18) on the lower transport side and the floor soil filling device ( 6) and a seeding device (7), a drug supply device (94) for supplying the drug to the seedling pot (5) is provided, and the drug supply position of the drug supply device (94) and the hooking position on the upper side of conveyance And the distance between the drug supply position of the drug supply device (94) and the hooking position on the lower conveyance side are set shorter than the length of the nursery device (2) in the conveyance direction.

  Therefore, since the medicine is supplied to the seedling pot (5) before sowing by the medicine supply device (94), the supplied medicine is located below the seed in the seedling pot (5) sowed. Further, the distance between the medicine supply position of the medicine supply device (94) and the hooking position on the upper side of conveyance and the distance between the medicine supply position of the medicine supply device (94) and the hooking position on the lower side of conveyance are set as seedling raising devices. Since it is set shorter than the length in the transport direction of (2), the seedling raising device (2) that is in the medicine supply position at the medicine supply position is transported on the protrusion (17a) of the transport tool (17) on the upper transport side and on the lower transport side. At least one of the protrusions (18a) of the tool (18) acts to hold the seedling device (2) firmly so that the position of the seedling device (2) during supply of the drug does not shift. In addition, since the hooking position on the upper transport side and the hooking position on the lower transport side are set with an interval longer than the length in the transport direction of the seedling raising device (2), the interval between the seedling raising devices (2) The nursery device (2) can be sequentially conveyed to the medicine supply position.

  Therefore, since the supplied medicine is located below the seed in the sowing seedling pot (5), the medicinal effect that dissolves and acts on the seedling by irrigation or the like is less likely to act directly on the seed, resulting in poor germination due to the medicinal effect. And poor growth. Furthermore, even if the next seedling device (2) hits against the seedling device (2) being sown, the position of the seedling device (2) during supply of the drug can be prevented from shifting, and the drug is properly supplied to the seedling pot (5). it can. In addition, the nursery device (2) can be sequentially transported to the drug supply position with a space between the nursery devices (2), and the drug from the drug supply device (94) is supplied to the nursery device (2). Without being dropped through the gap, and generation of useless medicine can be prevented.
