In FIG. 5, with the upper clamper 29 holding the spike portion 14 of the spikelet seedling 21, the lower part of the cotyledon of the seedling shaft is cut obliquely and Y is held while holding the spike portion 14.
The rotation base 31 is rotated about the axis by about 180 degrees. When the rod 36a of the air cylinder 36 is extended during this rotation, the slide bar 38 is extended upward from the base block 33, and the slide bracket 39 is raised upward along the slide rail 35.

In this way, when the upper clamper 29 stops at the turning end position, the ear 14 held by the upper clamper 29 waits at a position above the clip 10 applied to the tip of the base 15. It becomes a state. From this state, when the rod 36a of the air cylinder 36 is contracted, the slide bracket 39 moves obliquely downward along the slide rail 35 together with the rod 36a, the upper clamper 29 descends, and the ear 14 inside the clip 10. Inserted in.

Then, after inserting the spikes 14 and closing the clip 10, the rod 40a of the air cylinder 40 for pushing up is further extended to move the slide bracket 39 downward, thereby simultaneously moving the upper clamper 29. Push a little more in the insertion direction. At this time, the rod 4
The amount by which 0a extends and the air cylinder 40 (that is, the upper clamper 29) can move downward is restricted by the amount of the gap a between the bolt 41 and the connecting plate 37, and therefore only the amount corresponding to this gap a. It is pushed more.

Next, FIGS. 7 and 8 are views showing a state in which the seedlings after the grafting process are forcibly moved by the seedling gathering device.

That is, the seedling gathering device 42 is arranged on the downstream side of the stock transfer conveyor 24, and the seedling pot 19 'for which the grafting work is completed is forcibly moved to the advancing direction side of the stock transfer conveyor 24. By doing so, it does not interfere with the next seedling treatment. The seedling gathering device 42 includes a seedling gathering body 43 for separating the treated seedling on the downstream side of the treated seedling, and the treated seedling gathering body 43 removes the treated seedling from the treated seedling through a cam and a rope (not shown). It is designed to be moved to a position where it can be released.

The seedling gathering body 43 has a groove 44 (see FIG. 1).
It forms a circular arc-shaped plate body that can be rotated along with, and its lower side surface is formed as an inclined surface 45 that descends from the front to the rear in the rotation direction.

For this reason, conventionally, as shown in FIGS. 9 and 10, the seedling gathering body 43 'is formed on the inclined surface 45' which rises from the front to the rear in the rotating direction. There was a risk that the leaf portion of the seedling would be lifted up and the joint portion of the treated seedling would be pulled out. However, according to the present embodiment, since the inclined surface 45 is inclined opposite to the conventional one, this inclination The surface 45 serves to press the seedling downwards, thus eliminating the risk of pulling out the joint of the treated seedling.
