(a)) Immediately thereafter, the pot seedlings a taken out from the seedling tray 13 by the seedling take-out nails 10 are released and supplied to the planting nails 15 (FIG. 5 (b)). In the planting nail 15, the medicine E is stored under the pot seedling a, that is, in a state of being located at the root of the stock.
In this state, the rotation of the planting arm 52 causes the planting claws 15 to move.
Descends and enters the ridge G (FIG. 5 (c)). The planting claws 15 start to rise, and the two claws
The drug E and the potted seedling a are simultaneously released into the planting hole G1 formed in the ridge G by opening 15a and 15b (FIG. 5 (d)). Then, after the planting claws 15 are raised, the potting seedlings a planted by the soil covering wheel 11 are covered with the progress of the machine, and the planting of one plant is completed (FIG. 5 (e)). As described above, in the present embodiment, it is possible to apply the medicine to the soil at the same time as transplanting the seedlings.
Can be effectively administered to the root of the strain, so that sufficient medicinal effects can be obtained. Further, since the medicine is administered simultaneously with the seedling transplantation, a uniform drug effect can be expected irrespective of the traveling speed of the vegetable transplanter Y. In this embodiment, the dispensing device D is configured as described above, and the timing of supplying the drug E to the implant claw 15 is determined by the position of the guide roller 58 of the implant arm 52 raised. There is no limitation. That is, any configuration is possible as long as the medicine E can be supplied into the planting nail 15 before the pot seedling a is supplied. The timing of supply to 15 can also be determined. Next, another embodiment will be described with reference to FIG. The reference numerals used in the drawings are the same as those in the previous embodiment. This differs from the previous embodiment in the timing of opening and closing the claw bodies 15a and 15b of the planting claw 15 and operates as follows. That is, the planting claw 15 starts to descend with the pot seedling a stored therein (FIG. 6 (a)), and the claw bodies 15a, 15
b rushes into the soil while closed, and passes the bottom dead center while closed (FIG. 6 (b)). Then, similarly, the nail members 15a and 15b start to rise while being closed, and a planting hole G1 is formed in the ridge G (FIG. 6).
(c)). At this time, the nail body 15 is placed around the opening of the planting hole G1.
Since the tips of a and 15b are not touched, there is no danger of breaking the shape of the planting hole G1. When the tip of the planting nail 15 comes out of the soil, the nail bodies 15a and 15b start to open and drop the pot seedling a (FIG. 6 (d)). The state is completely accommodated in the hole G1 (FIG. 6E). As described above, since the claws 15a and 15b do not open in the ground, a large load is not applied, and no excessive force is applied to the drive system. The opening / closing timing of the claws 15a and 15b is as follows.
For example, it can be applied to tobacco and the like. That is, for a plant having a large seedling such as tobacco, the size of the planting nail 15 is increased.
Since a large load is applied to the opening and closing corresponding to the increase of 15a, 15b, a torque limiter or the like may operate. Also,
When the claws 15a, 15b start to open in the soil, the planting holes may not be formed cleanly. Therefore, by setting the opening and closing timing of the nail members 15a and 15b as described above, a planting hole G1 having the same shape as the planting nail 15 and hard to collapse is formed. , 15b can be prevented from being broken or damaged without imposing a load on the drive system that opens and closes. Although the vegetable transplanter Y according to the present invention has been described as a walking type in the above embodiment, it may be a riding type. According to the present invention, a seedling supply device, a seedling planting device, and a seedling removal device are provided, and the seedling removal device takes out seedlings from the seedling supply device. In a vegetable transplanter that releases and supplies to a planting nail consisting of a divided nail body that can be opened and closed and transplants seedlings with the planting nail, the drug supply of the drug dispensing device above the upper stop position of the planting nail Establish a location and plant
On the rail that guides the planting arm that supports the nails up and down
Inside the part, for drum rotation to open and close the rotary drum
