SUMMARY OF THE INVENTION In the transplanter described above,
The (seedling frame) insertion port is formed in the upper part, and the guide plate with the (seedling frame) extraction port formed in the lower part is curved in the same direction. The seedlings with soil are projected to the lateral feeding means.

However, a feeding hole is formed on the side edge of the seedling box, and the seedling box is vertically fed by the action of the feeding claw that is engaged with and disengaged from the feeding hole, and the seedling box is curved at the action portion of the seedling pushing rod. Therefore, it is difficult for the pot part and the extruding rod to accurately face each other, and it is difficult to extrude the horizontal row of soil-grown seedlings all at once. Further, the vertical feeding of the seedling box is performed by intermittently driving the feed pawl with the feed pawl engaging the feed pawl, and a crack is generated in the feed pawl by the repeated action of the engaging force of the feed pawl. It is easy to have problems with the durability of the seedling box, and it is difficult to accurately engage the feed claw with the feed hole due to vibrations in the upland field, which causes a vertical feed error.

In addition, the feeding claws are actuated in the feeding holes formed on the side edges of the seedling box to feed the seedling box longitudinally. There was a problem that the feed hole was cracked by repeatedly engaging and disengaging the claw. In view of the above, the present invention focuses on the fact that a large number of vertically and horizontally arranged pot portions are provided on the back surface, and voids are formed between the pot portions, and by utilizing the voids to act the feed claws. When vertically feeding the seedling box, the voids are surely formed to ensure vertical feeding, and the seedling pushing means and the pot portion are accurately opposed to each other, thereby pushing out the seedlings with soil in a horizontal row in the pot portion. The purpose is to be accurate.

[0006]

According to the present invention, a seedling box 5 is provided with a plurality of pots 52 arranged vertically and horizontally on a back surface thereof.
1 is provided with a seedling box vertical feeding device 39 for vertically feeding the seedling 1 from the upper side to the lower side along a curved seedling box guiding means 45 having an insertion port 49 in the upper part and an outlet 50 in the lower part. In the middle of 45, the seedling 53 with soil in the pot portion 52 of the seedling box 51
It is a transplanter provided with the seedling pushing means 40 for pushing the seedlings to the seedling lateral feeding means 41, and the following technical means are taken to achieve the above-mentioned object.

That is, according to the present invention, the seedling pushing means 4 is used.
It is characterized in that a substantially linear vertical guide portion 46 is formed in the portion of the seedling box guide means 45 facing 0.

[0008]

During the transplanting operation, the seedling box 51 is loaded from the insertion port 49 of the curved seedling box guiding means 45 of the transplanting machine 1 which runs in the longitudinal direction across the ridges 3. The seedling box 51 is provided with a large number of pots 52 arranged vertically and horizontally on the rear surface,
Soil seedlings 53 are raised in the pot portion 52.

The seedling box 51 loaded from the insertion port 49 of the seedling box guiding means 45 drives a pair of left and right feed claws 55 that move in and out of a gap 54 between vertically adjacent pot portions 52. By swinging in the feeding direction, that is, in the downward direction by the means 74, intermittent feeding is performed from the upper side to the lower side by one pitch via the pot portion 52. Due to this intermittent feeding, even if the seedling box 51 is curved along the curved portion of the guide means 45, a substantially linear vertical guide portion 5 is provided in the middle thereof.
Since it has 6, the gap 54 between the pot portions 52 is surely formed when passing through here, and the feeding claw 55 is surely engaged and disengaged, while the seedling box 51 does not need a feeding hole or the like, which is versatile. Something can be used as it is.

Further, in the seedling box 51, which is intermittently fed one pitch at a time from the upper side to the lower side, when the earthed seedlings 53 of the pot portions 52 in a horizontal row are pushed by the seedling pushing means 40 onto the lateral feeding means 41 during that time, Since the vertical guide portion 56 is opposed to the seedling pushing means 40, the positions of the pot portion 52 and the seedling pushing means 40 are determined, and the push of the seedlings 53 with soil is ensured. Then, the lateral feed means 41 is used to attach the seedling 53 to the soil.
The seedlings 51 are emptied from the take-out port 50 of the seedling box guide means 45 by laterally feeding the seedlings one pitch at a time and planting them in the ridges 3 by the planting device 21 provided at the sending end. Is released to.
