Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a seeding device for pot sheet paper.

(Prior Art) Conventionally, seedlings with soil for rice transplanters have progressed from seedlings with soil sown to seedlings with soil sown in rows, and recently, seedlings with soil in pot sheets using pot sheet paper have become popular.

(Problem to be Solved by the Invention) Pot sheet paper 1 has about 16 pots 2 arranged in parallel in the horizontal direction and about 17 pots 2 arranged in parallel in the vertical direction, as shown in Fig. 1. Conventionally, three seeds were sown in each pot 2 by hand, but since hand sowing is difficult, sowing was done by machine.

Also, as shown in FIG. 3, when the pot sheet paper 1 is placed inside the storage case 3, the pot sheet paper 1
Since the pot itself is very light and the lower end 4 is formed with unevenness, the lower end 4 of the pot 2 is stored with it slightly raised above the bottom of the storage case 3, and in this state, the soil covering 5 is poured from above. Then, the covering soil 5 leaks from the through hole 6 formed in the lower end portion 4.

(Means for Solving the Problems) In the present invention, when mechanically sowing the pot sheet paper, the pot sheet paper itself is made of paper and is not flat, and the fit in the storage case in which it is stored is not certain. Before carrying out a series of seeding operations, the pot sheet paper is pressed from above with a pressing device to ensure that it is stored in the storage case, and then a series of seeding operations is carried out. A pot sheet paper 1 formed by forming a large number of pots 2 vertically and horizontally, each having a through hole 6 approximately in the center.
is fitted into the drawer-shaped storage case 3 from above with the through hole 6 facing down, and is placed on the horizontal moving table 13 of a conveyor-type seeding device and sown on the pot sheet paper 1 while being moved. In the pot sheet paper 1 covered with the seedling box 10 and turned over, the horizontal transfer table 13 is provided with at least a covering soil supply device 27 or a bed soil supply device 65, and the top of the soil covering supply device 27 or the bed soil supply device 65 is On the side, a shaft rod is formed which is long in the direction of conveying the pot sheet paper 1, and it is movable up and down in parallel to the pot sheet paper 1, and waits at a position lower than the upper surface of the pot sheet paper 1 to transfer the pot sheet paper 1 to the storage case 3. The seeding device is equipped with a pressing device for elastically pressing inside the seeding device, and the pot sheet paper 1 is pressed into the storage case 3 by the pressing device, and then the covering soil 5 or the bed soil 9 is supplied. .

(Example) Fig. 1 shows a state where the pot sheet paper 1 is being stored on one side of the storage case 3, and Fig. 2 shows the same storage state. Line them up and fit them together. When the pot sheet 1 is placed in the storage case 3 in this manner, the lower end 4 of the pot 2 is slightly raised above the bottom of the storage case 3, as shown in FIG. This is because the pot sheet paper 1 itself is very light and the lower end portion 4 is formed with unevenness. If the covering soil 5 is thrown in from above in this state, the covering soil 5 will leak from the through hole 6 formed in the lower end 4, resulting in a situation as shown in FIG. 3, so this is prevented.

The storage case 3 has a drawer shape and is sized to fit two approximately square pot sheets 1 side by side, and has a protrusion on the top surface of its bottom plate to prevent each pot sheet paper 1 from moving. Form. The pot sheet paper 1 is made of a water-soluble paper material, and each pot 2 is formed to have a substantially regular square opening when viewed from above, and becomes narrower toward the lower end 4 when viewed from the side. A through hole 6 is formed in the lower end 4 of the pot 2. Seeds 7 sown in pot 2
The bud 8 extends upward from the through hole 6. That is, the pot sheet paper 1 is fitted into the storage case 3 and covered with soil 5 in the pot 2, about three seeds 7 are sown on the covered soil 5, and bed soil 9 is supplied on top of it. (Fig. 5), and cover the seedling raising box 10 from above (Fig. 6).
), remove the upper storage case 3 by turning it over, put top soil 11 into the gap between each pot 2 (Fig. 7), and grow for a certain period of time.
More buds 8 emerge upward.
