An arc-shaped box pressing body 33 is integrally provided on the shaft, and a box raising body 34 is integrally provided on the support shaft 27 of the swing link 28. When the lever 30 is set to the rear position, the box pressing body 33 is in a standing storage posture by the action of the ammunition 32d that urges the swing arm 32 as shown in FIG. 7 is pressed from the back side to hold it in that posture. Moreover, in this state, the box raising body 34
Is located at the bottom position of the box mounting table 5 and has already been planted with seedlings P.
Is waiting for the empty seedling box 7 in which all are planted to be vertically fed and overlapped to the upper side. And empty seedling box 7
When the lever 30 is overlapped on the box raising body 34 and the lever 30 is operated to the front position to pull the rod 29 forward, the box raising body 34 is erected and rotated upward and rearward as shown in FIG. When the seedling box 7 is raised, the box pressing body 33 retracts and swings upward to wait for the rising seedling box 7, and when the lever 30 is returned to the rear, the backside support of the raised seedling box 7 is obtained. In this way, a plurality of seedling boxes 7 are stored.

In the figure, 35 is a box detection switch provided on the box raising body 34, which detects that the seedling box 7 has overlapped on the box raising body 34 and has reached the storage position. The alarm means (not shown) is activated. Further, 36 is a box slip stopper provided on the box mounting table 5, which prevents the seedling box 7 freely released from the vertical feed gear 11 from slipping inadvertently. Is a comb body for combing the planted seedlings P housed in the seedling box 7.

In the embodiment of the present invention constructed as described above, the seedling box 7 placed on the box placing table 5 (the bottom plate 8 is removed)
The planted seedlings P stored in the seedling storage chamber located at the seedling drop opening 18a are pushed out by the operation of the seedling dropping body 13 and are dropped and delivered downward, and then forward and backward to the seedling feeding bodies 19 and 20. It will be transferred to the seedling receiving body 24 side below while being regulated to fall while both sides are clamped. And this planted seedling P
When the seeds were transferred to the seedling receiver 24,
The planting claws 25 scrape off the planted seedlings P and plant them on the rice field. On the other hand, the seedling receiving body 5 is laterally fed by the amount of one seedling storage chamber by the operation of the lateral feeding mechanism, and when it is at the end of the lateral feeding movement, it is vertically fed by the amount of one seedling storage chamber. As a result, the next series of operations described above will be continued, which allows continuous planting seedlings P to be timed.
Can be planted.

As described above, in the present invention, the planting of the straw seedlings is performed in the seedling box 7
The seedling box 7 of the box mounting table 5 is empty when the planted seedlings P are supplied to the planting claws 25 side, although the planted seedlings P are sorted and sorted according to the sprout standard stored in. Move to the lower part and overlap the upper part of the box raising body 34. And detection switch
When 35 detects the box, the operator pulls the lever 30 to the front to swing the box raising body 34 upright and swing the box pressing body 33 upward. As a result, the empty seedling box 7 is sent to the storage frame 26 side in the standing storage posture, and then the lever 30
By returning to the original state, the box raising body 34 is positioned at the bottom position of the box placing table 5 to wait for the seedling box 7 which is next emptied and sent, and the box pressing body 33 swings downward. The rear surface of the seedling box 7 that has been moved upright is elastically pressed to prevent inadvertent fall and drop, and by repeating this, a plurality of sheets (up to three sheets in the embodiment) The empty seedling boxes 7 can be stacked and stored in a standing posture.

Moreover, since this storage is for stacking the empty seedling boxes in a standing posture, a storage space that does not get in the way like the conventional seedling box 7 which is stacked in a horizontal posture is provided. It is not necessary to widen the space between the box mounting table 5 and the planting claws 25 in order to secure it, and the arrangement configuration can be as close as possible. Therefore, the transfer route of the planted seedling P from the seedling box 7 to the planted nail 25 can be shortened, and the planted seedling P can be shortened.
It is possible to reliably prevent a problem that the seedlings are clogged or fallen on the way, and it is possible to plant an orderly and highly accurate planting seedling P with high efficiency.

Needless to say, the present invention is not limited to the above-mentioned embodiment, and the point is that a seedling box is placed on a box placing table equipped with a mechanism for lateral feeding and vertical feeding, and is housed in the seedling box. In the transplanter that supplies the planted seedlings that have been planted to the planting device arranged below the box placing table and transplants them, at the end of the vertical feeding path of the box placing table, direct the empty seedling box to the rear. Any concrete means can be used as long as it is provided with a box storage body configured to have a box raising body to be raised and a box pressing body for controlling the tilting of the raised seedling box. is there. And the operation of the box raising body and the box pressing body does not have to be manually performed as described above,
It is also possible to automatically perform the operation in connection with the detection that the empty seedling box is raised up and overlaps the body. Further, in this case, it is more convenient to detect this when a required number of empty boxes are stored and issue an alarm.

[Operation and Effect] In short, since the present invention is configured as described above, a seedling box containing planted seedlings is used and mounted on a box mounting table equipped with a mechanism for vertical and horizontal feeding. The seedlings that have been emptied are supplied to the lower planting device side for transplanting seedlings to the field, but the empty seedling boxes are stored in the boxes placed at the end of the vertical feed path of the box mounting table. By the operation of the box raising body and the box pressing body, they are stored in a posture in which they are erected rearward and are prevented from falling down. As a result, there is no need to widen the space between the box mounting table and the planting claws to secure a storage space that does not get in the way, unlike the conventional one in which the seedling boxes are stored in a stacked state in a horizontal position. Since it can be arranged as close as possible, the transfer route of the planted seedlings from the seedling box to the planting device can be shortened, and the troubles that the planted seedlings are clogged or collapsed on the way can be reliably prevented. Therefore, it is possible to perform transplantation of planted seedlings in a highly orderly and highly accurate manner.
