Next, the operation will be described. When the seedling container 1 is supplied to the seedling container automatic supply device 13 at the start end of the transfer table 12, the lowermost seedling container 1 is placed on the support rail 15. In this state, the motor is energized, and the rotating shaft 4
5 and the drive gear 47 is rotated by the rotating shaft 45, the transport chain 17 moves, and the transport chain 17
Abuts on the rear surface of the seedling raising container 1 at the lowermost stage and conveys the seedling raising container 1, and the second stage seedling raising container 1 from the bottom comes into contact with the upright rod 14 on the front side of the seedling raising container automatic feeding device 13, Only the lowermost seedling raising container 1 passes below the standing rod 14.

In this case, since only a pair of left and right support rails 15 are provided below the automatic seedling raising container supply device 13, the structure is rational and the manufacturing and assembly is simple. The seedling container 1 is transported by the right and left transport chains 1.
Since the transport hook 21 is attached to the, the manufacturing and assembly are also easy. Thus, the seedling raising container 1 transported by the transport hook 21 reaches below the floor soil supply device 26, but the support belt 40 is provided below the floor soil supply device 26. The lower surface is the support belt 40
And the floor soil 11 is supplied from above in this state, so that the floor soil 11 is supplied from below the pot 2 without leaking.

1 is pressed, closed tightly, and the floor soil 11 does not fall down even if it is a pot 2 having a bottom shape. In this case, the floor soil 11
Similarly, the lower surface of the seedling raising container 1 is in close contact with the upper surface of the support belt 40, so that the floor soil 11 does not leak from below the pot 2 even when pressed from above by the pressing protrusion 31. Since the flat belt support plate 50 is provided below the support belt 40, the support belt 40 is kept in contact with the floor support 11 even when it is supplied with the floor soil 11 and pressed by the pressing protrusion 31. The support belt 40 is in close contact with the lower surface of the seedling raising container 1, and the floor soil 11 does not leak from below the pot 2.

Accordingly, the support belt 40 is formed by looping the endless belt around the rear roller 42 and the front roller 43, and the support belt 40 itself does not support the seedling growing container 1, but is provided below the support belt 40. Belt support plate 50
, The structure can be simplified. Further, as described above, since the seedling raising container 1 is transported by the transport hook 21 of the transport chain 17, the pressing projections 31 of the pressing device 30 are provided.
Synchronization with the pots 2 of the seedling raising container 1 is reliable. That is, since the moving speed of the transfer hook 21 of the transfer chain 17 is set to be larger than the moving speed of the support belt 40, the seedling raising container 1 which stops relatively and rides on the support belt 40 is transferred to the transfer hook 17. 21 and push forward, the synchronization between the pressing protrusion 31 of the pressing device 30 and each pot 2 of the seedling raising container 1 is secured.

Further, since the support belt 40 is driven and rotated by the front roller 43 attached to the rotating shaft 45 via the one-way clutch 46, the support belt 40 moves forward together with the seedling raising container 1 for some reason. In this case, the one-way clutch 46 causes the front roller 43 to be rotated faster by the rotation shaft 45, so that the support belt 40 does not hinder advance. The drive gear 47 of the transport chain 17 is fixed to the left and right sides of the rotating shaft 45, and the drive gear 4
Since the transfer chain 17 is wrapped around the driven gear 7 and the passive gear 22, the input gear 48 is fixed to the end of the rotating shaft 45, and the rotating shaft 45 is provided with the front roller 43 via the one-way clutch 46. The rotation shaft 45 also serves as a rotation input shaft for the transport chain 17 and the front roller 43, thereby simplifying the configuration.
