DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seedling container used for sowing by a sowing plant.

[0002]

2. Description of the Related Art As a sowing plant, there are a sowing process for paddy rice, a sowing process for vegetables and flowers,
In addition, there is a method in which both a sowing process for paddy rice and a sowing process for vegetables and flowers are performed. In the seeding process for paddy rice, a nursery box for paddy rice seedling cultivation formed so as to cultivate mat-shaped seedlings is used as a seedling raising container . Conventionally, in a sowing process for vegetables and flowers, a tray for cultivating vegetables and flowers seedlings in which a plurality of seedling pots for growing pot seedlings are arranged vertically and horizontally is used for paddy rice cultivation. Placed in a nursery box for
It was intended to be used as a nursery container .

[0003]

However, since the seedling pot portion of the tray is generally formed so that the seedbed is deeper than that of the seedling raising box, the tray for cultivating vegetable and flower seedlings is simply used. When the seedling growing container is used for sowing vegetables and flowers by the seeding plant by being placed in the seedling raising box for paddy rice seedling cultivation, as shown in FIG. 2 rim 2a
Is formed between them. In addition, in the seeding process for seeds for vegetables and flowers by the seeding plant, for example, at the time of floor soil supply or cover soil supply, the floor soil and cover soil supplied to the seedling pot portion 2p of the tray 2 are removed from the gap h by the seedling raising box 1.
And between the tray 2. Then, the seedlings that have grown during the growing season grow out of the drain hole 2h formed in the seedling pot portion 2p of the tray 2 toward the soil that has entered between the seedling raising box 1 and the tray 2, There has been a problem that it is difficult to extract the pot seedlings P from the seedling pot portion 2p.

[0004] It is an object of the present invention to provide a method that allows soil to enter between a nursery box and a tray, so that seedlings grow out of a drainage hole formed in a seedling pot of the tray, and the seedlings from the seedling pot are removed. It is an object of the present invention to eliminate the inconvenience of making it difficult to extract the image.

[0005]

In order to achieve the above object, according to the first aspect of the present invention, a nursery box is provided in a nursery rather than in the nursery box.
A plurality of deep seedling pots are formed so that they are aligned vertically and horizontally.
Trays for seedling cultivation
Through a ring-shaped spacer that closes the gap between the peripheral edges
Placed .

In a second aspect of the present invention, in the first aspect,
At the time of sowing by the sowing plant, the same number of sensing units as the seedling pots are provided on the lateral outer surface of the spacer so that the positions of the seedling pots arranged in the feeding direction by the conveying means are sensed by the sensing sensors. It was formed corresponding to the position of the pot.

[0007]

According to the first aspect of the present invention, a ring-shaped spacer for closing a gap between the peripheral portions is interposed between a seedling growing tray and a seedling raising box on which the tray is placed. Therefore, no gap is formed between the periphery of the seedling raising box and the periphery of the tray, so that the tray is not supplied when supplying the floor soil or covering soil in the sowing process for vegetables and flowers by the seeding plant. The floor soil or cover soil supplied to the seedling pot section of the seedling does not enter between the seedling raising box and the tray. In other words, since there is no soil between the seedling raising box and the tray for the seedlings to grow from the drainage holes in the seedling pots, the seedlings no longer grow from the drainage holes in the seedling pots. There is no inconvenience that it is difficult to extract the pot seedlings from the seedling pots due to the seedlings grown from the drain holes of the pots.

According to the second aspect of the present invention, the same number of sensing portions as the number of seedling pot portions are formed on the lateral outer surface of the spacer corresponding to the positions of the seedling pot portions. The position of each seedling pot portion arranged along the feeding direction can be sensed by the sensing sensor. In other words, at the time of sowing in the sowing process for vegetables and flowers, since one seed is surely sowed for each seedling pot, the seedling pots of the seedling pots arranged in the feeding direction by the transporting means are sowed. It is necessary to detect the position and perform intermittent feeding such as temporarily stopping the transport of the seedling container by the transport means in a state where the position of the seed supply port of the seeding apparatus and the position of the seedling pot portion match in the transport direction. ,
In the related art, the position detection of each seedling pot is performed from a gap formed between the periphery of the seedling raising box and the periphery of the tray.
If the gap formed between the peripheral portion of the seedling raising box and the peripheral portion of the tray is closed as in the present invention, a problem arises in that the position of each seedling pot cannot be detected. Therefore, in the second aspect of the invention, the inconvenience is solved by forming the same number of sensing portions as the number of seedling pot portions on the lateral outer surface of the spacer corresponding to the positions of the seedling pot portions.
Generally, 128 (8
× 16) The number of seedling pots formed and 200
Since there are some (10 × 20) seedling pot portions formed, 16 sensing portions are formed so as to correspond to those having 128 seedling pot portions formed on one lateral side of the spacer. If 20 sensing portions are formed so as to correspond to 200 seedling pot portions formed on the other side of the spacer, one spacer can correspond to two types of trays. Therefore, it is possible to reduce the equipment cost while solving the above inconvenience.

[0009]

Thus, according to the first aspect of the present invention, the seedlings grow out of the drainage hole formed in the seedling pot portion of the tray toward the soil that has entered between the seedling raising box and the tray. The inconvenience of making it difficult to extract the pot seedlings from the seedling pot section can be solved.

[0010] According to the second aspect of the present invention, the position of each seedling pot section lined up in the feeding direction by the conveying means can be detected by the sensing section formed on the lateral outer surface of the spacer. While the gap formed between the peripheral portion and the peripheral portion of the tray is closed, one seed can be surely sown for each seedling pot portion.
