Igusa seedlings are tightly connected by underground rhizomes in a roughly circular shape with a diameter of about 8 to 10 centimeters, and these mother plants are compressed and loaded without any gaps into the seedling stand of a conventionally known rice transplanter. A method is proposed by the applicant. This seedling stand usually has a rectangular planar shape, is inclined on one side in the longitudinal direction, and is reciprocated with a constant stroke in the left and right directions. A seedling planting body that moves up and down reciprocates takes out seedlings and plants them on the rice field. In addition, there are some devices that are equipped with a lower seedling feeding mechanism that feeds the seedlings intermittently at the bottom of the seedling platform so that the seedlings move from the upper side of the slope to the lower side of the slope. No. 120923).
ところが、稲の苗のように方形に一枚に形成さ

なつて欠株を生ずる問題がある。
However, if it is a single square pine seedling like a rice seedling, there is no problem, but if it is a rush seedling as mentioned above, it must be loaded by compressing many circular mother plants. As a result, when the seedlings are fed, the mother plant is pushed upwards, creating gaps between the mother plants and the seedlings are not sent evenly to the seedling take-out port.As a result, the seedlings are planted unevenly by the seedling transplanter. There is a problem that over time, stock shortages occur.

ない。 The rush seedling planting device with this configuration first has the following features:
The mother plants B of rush seedlings are sequentially supplied from above the slope of the seedling platform 3, and transferred so as to be pushed to the lower end side of the slope via a forced feeding mechanism (not explained). This mother plant B is further fed by a lower seedling feeding mechanism 25 that reciprocates within a certain range through link members 26 and 27 as shown in FIG. The seedlings are then sent to the seedling take-out port 3a side. During the feeding action by the lower seedling feeding mechanism 25, the mother plant B is slightly floated to the seedling take-out port 3.
Mother plant B sent to side a and located in window 3b
are supported by the seedling support plate 25 and will not fall.

In conjunction with the feeding action of the lower seedling feeding mechanism 25, the first
As shown in FIG. 5 and FIG. 5, the tip of the upper seedling feeding claw 20, which reciprocates back and forth around the swing shaft 14, is pushed from above and pressed against the seedling platform 3, and the cam 17 and actuating rod 19 , actuating piece 22, holder 2
1, the upper seedling feed claw 20 is moved to the seedling take-out port 3a.
Move to the side and move the mother plant B to the seedling removal port 3a. A planting body 9 reciprocates this moved mother plant B by drawing a trajectory A up and down via a crank arm 8 and a swinging arm 10 by rotation of a planting body drive shaft 6.
The separation claw 11 separates the parts as shown in FIGS. 1, 3, and 4. During this separation, the separation claw 11
The root of the mother plant B, which has a pointed conical tip and is firmly connected by a wedge action, is separated and taken out by being held between a pair of separating claws 11, 11.
When the separating claws 11 enter the rice field, the planting needle 12 protrudes between the separating claws 11, 11, plants the clamped seedlings into the mud, and ascends along the trajectory A. By repeating these operations, continuous planting of Igusa seedlings is carried out. The vertical movement of the planting needle 12 is performed by the reciprocating movement of the planting body 9, as is well known, by a built-in cam, spring, etc.
0 is at the 20 position when the mother plant B is pushed forward, as shown in FIG. It is operated by a rod 19, an operating half 22, a holder 21, a spring 24, etc.
