SUMMARY OF THE INVENTION In the above-mentioned conventional structure, a seedling placing unit in which seedlings for planting are placed and housed in advance is slid on a seedling stand, and the bottom plate of the seedling placing unit is pulled backward to operate the seedling. This is to facilitate the supply work. However, in the above-described conventional structure, since the seedling pressing plate maintains the same level, on the lower side in the transfer direction, when the placed seedlings are lowered toward the vertical feeding device,
Since the pressing action point by the seedling pressing plate is located above the root part of the seedling, even though the root part is locked by the vertical feeding device, the pressing plate works by its own weight and the seedling is tilted forward. There was still room for improvement because the posture was disturbed. The present invention aims to eliminate the above-mentioned problems.

[0004]

According to a characteristic construction of the present invention, in the seedling transplanting machine described at the beginning, the lower end of the pressing plate is the vertical feeding device at a lower side portion of the seedling placing table in the seedling transfer direction. The guide portion is provided with a guide mechanism for guiding the pressing plate so that it can be dropped to the lower side to be forcibly transferred by being locked by the locking claw.

[0005]

[Function] On the upper side of the seedling transfer direction, a smooth pushing action by the own weight of the seedling pressing plate achieves a seedling holding action with less posture disturbance, and in the area where forced feeding is performed by the vertical feeding device, the seedling pressing plate is also the same. By locking the seedlings in the vertical feeding device and synchronizing the feeding operation of the vertical feeding device, the seedlings can be reliably transferred without any disturbance in posture.

[0006]

[Effects of the Invention] Therefore, by reasonably improving the seedling stand, even if the seedling stand is constructed in a form that facilitates seedling supply work, the seedlings can be reliably and almost never fallen over the entire seedling transfer area. It can be sent out stably,
It was decided that planting work could be performed with less outbreaks and less damage to seedlings.

Next, the seedling supply structure will be described. For planting seedlings, weed seedlings that have been pre-divided from the mother stock are provided in the seedling supply box 9
In order to supply seedlings, the seedling supply boxes 9 are mounted and supported on a preliminary seedling storage stand 10 of a traveling machine body, and the seedling supply boxes 9 are slid on the seedling stand 4 and mounted. I am doing it. As shown in the figure, the seedling supply box 9 is composed of a box body capable of holding strawberries in an upright posture, and has an intermediate partition wall 11 formed at the center for preventing the placed seedlings from falling sideways. Further, the seedling supply box 9 is fixed in the state where it is mounted on the seedling stand 4, so that the planting work can be performed as it is. That is, as shown in FIGS. 1 and 2, the bottom surface is provided so as to be located at a level slightly higher than the seedling placing surface 4a of the seedling placing table 4, and is placed on the lower side of the seedling placing table 4 in the seedling transfer direction. It is located above the provided vertical feed device 12 with protrusions so that it can be mounted by sliding without interfering with the vertical feed device 12. Further, as shown in FIG. 4, the bottom portion of the seedling supply box 9 has a double structure, and one portion on the tip side is slidable back and forth.
In addition, the front wall 14 on the tip side in the seedling supply direction is pivotally connected so as to be freely openable / closable and pivotally biased to a standing posture. The fixed bottom plate 15
However, it constitutes the seedling placement surface A during the planting work. On the slide bottom plate 13 of the seedling feeding box 9, an operating portion 16 is extended toward the rear end portion, and the operating portion 16 is provided at the rear end portion of the seedling feeding box 9 so as to prevent sliding movement during transportation work. A position holding mechanism 18 is provided for engaging with and engaging with the locking hole 17 of FIG.

When the seedling supply box 9 is slid into the seedling placing table 4 up to an intermediate position (see FIG. 3A), the seedling placing table 4 is inserted.
The contact portion 20 provided on the bottom surface of the slide bottom plate 13 abuts the stopper 19 provided on the above to prevent further slide, and thereafter, the engagement of the position holding mechanism 18 is released, and When the seedling supply box 9 is slid, the slide bottom plate 13 is held at that position, and is engaged with the engaging portion 21 formed on the intermediate partition wall 11 so that the front wall 14 is guided in a horizontal posture. After that, the operation portion 16 is pulled backward to retract the slide bottom plate 13 to a position where the upper part of the vertical feed device 12 is opened, and the position holding mechanism 18 holds the position again. In this way, the planting work state can be set [see FIG. 3 (B)].

Further, in the seedling supply box 9, a pressing plate 22 is pushed from the rearmost portion of the placed seedling group to prevent the placed seedling from falling.
Is movably provided along a guide portion 23 arranged along the seedling transfer direction. That is, the guide portions 23 are formed on the left and right side walls 24, 24 of the seedling supply box 9, and the guide portions 23 are slid and moved by their own weight to push the seedlings. Then, on the lower side in the seedling transfer direction, the lower end of the pressing plate 22 is locked by the locking claw 25 of the vertical feeding device 12 and can be dropped downward for forced transfer S (of the guide mechanism). One example) is provided in the guide portion 23. That is, the guide portion 23 is formed in a U-shaped cross section, and the lower end portion of the pressing plate 22 is fixed bottom plate 1 on the upper side in the seedling transfer direction.
