Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a seedling raising plant for potted seedlings, and more specifically, the plant is formed in a downwardly expanding shape that is open downward, and an opening for seeding is formed at the upper end. A conveying device that loads a seedling growing container formed by integrally forming a number of pots side by side into a seedling growing box and transports the seedling growing container along a substantially horizontal direction; a bed soil supply device that supplies bed soil to the seedling growing container; and a bed soil supplying device. The present invention relates to a seedling raising plant for potted seedlings, which comprises a seeding device that supplies seeds to the pots that have been sown, and a soil covering device that supplies soil to the pots after sowing to cover the seeds.

[Conventional technology]

Conventionally, in a seedling-raising plant equipped with a device for supplying soil to a bottom-spreading pot of this type, seeding operations for raising seedlings have been carried out in accordance with the process shown in FIG.

That is, as shown in FIG. 6(a), first, the bed soil is supplied into the seedling growing box (4) loaded with the seedling growing container (3), and then the supplied bed soil is placed inside the seedling growing container (3). Each pot (2
) Scrape and level the bed soil with a rotating brush so that it is slightly recessed from the surface of the opening (1), and then
As shown in Fig. 6(b), guide holes (8) corresponding to the openings (1) of each pot (2) of the seedling raising container (3)
Load the mask (7) equipped with ... into the seedling growing box (4). Thereafter, a predetermined amount of seeds are sown into each pot (2) through the guide hole (8>) and opening (1) of the mask (7).After sowing, as shown in Fig. 6(c). As shown in FIG. 6, the mask (7) was removed from the seedling nursery box (4), and then, as shown in FIG. 6, it was covered with soil.

[Problem to be solved by the invention]

Spreading pots are an effective method for growing seedlings that are germinating in a small area in a dense manner without scattering them. In some cases, there are pots that do not exhibit the desired growth conditions, such as seedlings that are partially stretched or partially deviated in the horizontal direction. This is undesirable because it causes poor conditions for planting the potted seedlings in the field after germination using the planting machine, so there remains room for improvement.

The present invention aims to solve the above-mentioned problems.

[Means to solve the problem]

In order to achieve the above object, the present invention provides the potted seedling raising plant described at the beginning, which is provided with a compacting device for compacting the soil supplied by the bed soil supplying device and deposited in the gap between the adjacent pots. This is a characteristic configuration.

[For production]

In other words, as a result of investigating the causes of the irregularly growing seedlings mentioned above, it was found that this occurs when the pots of the irregularly growing seedlings are deformed, the roots are broken, etc., and the pots lose their shape. They discovered that preventing the pot mold from warping is an effective means of solving the problem.

Therefore, in order to prevent the pots from losing their shape, the pots can be reliably pressed and supported from the outside by compacting the "top soil" that has accumulated in the gaps between adjacent pots. It has been found that deformation due to spreading can be effectively suppressed.

Therefore, by compacting the upper portion using the compression device, it is now possible to prevent the pot from losing its shape later on.

〔Effect of the invention〕

Therefore, the setting of the compression device obtained through detailed observation and research on the series of growth conditions of seedlings in a potted seedling raising plant can suppress the shape of the pot and minimize the occurrence of irregularly grown seedlings. We were able to provide a seedling-raising plant for potted seedlings that can produce potted seedlings.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

As shown in Fig. 1, it is formed by integrally forming a number of pots (2), which are formed in a shape that opens downward and spreads downward, and has an opening (1) for seeding at the upper end, arranged side by side. A transport device (A) for loading a seedling growing container (3) into a seedling growing box (4) and transporting the seedling growing container (3) along a substantially horizontal direction;
a bed soil supply device (B) that supplies bed soil to the bed soil, a sowing device (C) that supplies seeds to the pot (2) to which the bed soil has been supplied, and a seeding device (C) that supplies seeds to the pot (2) after sowing. - A soil-covering device (D) that supplies soil to cover the seeds, and an irrigation device (E) that supplies water to the seedling-growing container (3) after supplying soil.
) etc. to pore) seedling raising plant is constructed.

``The seedling raising container (3) has a one-piece bottom made by straining pulp, and when manufacturing it, the bottom is not made with an opening (1) as shown in Figure 5 (a). After molding,
As shown in Figure 5 (0), by making an opening (1) in each bond (2) using a punching machine, etc., the structure of the net gawa can be simplified and the size can be kept constant. Sa opening (1)
The seeds are formed in a fixed position so that they can germinate in the fixed position without any hindrance.

After passing through the bed soil supply device (B), a leveling device (5) that levels the bed soil and a brush device (6) that scrapes the bed soil surface.
After passing through this brush device (6), the mask (7) is placed in the seedling raising (4) and sent to the next seeding process.

``As shown in Figures 2 and 3, the mask (7) is provided with guide holes (8) corresponding to the openings (1) of each pot (2) of the seedling raising container (3). , it features downward protrusions (10) corresponding to the gap portions (9) that expand upward between the pots (2).

A stabilizing roll (11) and a pressure roll (12) which are freely rotating around the horizontal axis acting from above the mask (7) are placed at the upper side of the transport of the seeding device (C) in this order. It is arranged from. The stabilizing roll (11) lightly presses the mask (7) downward from above, and functions as a presser for the mask (7>) during operation of the suppressing roll (12), which will be described later.

"The suppression roll (12) is placed on the bottom surface (1) of the mask (7)
