Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuous collecting pot for raising seedlings in which individual pots can be continuously drawn out by connecting them with a connecting piece, and more particularly, a continuous collecting pot in which a plurality of drawers can be drawn in parallel. It is about.

[0002]

2. Description of the Related Art As a continuous collecting pot for transplanting seedlings of this type, a square or hexagonal cylindrical individual pot body formed by expanding a paper or a thin film such as a paper is connected by a connecting piece. There is a body which is folded back so that the individual pots are displaced by 1/2 pitch, and the folded portions are adhered to each other with a water-soluble adhesive (for example, JP-A-54-28327). Japanese Patent Publication No. 4-79612
Reference). According to such a continuous collecting pot for raising seedlings, as a pressure-unbalanced state during storage, a large number of individual pots in a honeycomb form appear in a densely gathered state by expanding at the time of use. By filling the seeds with cultivated soil and sowing the seeds, it is possible to intensively grow a large number of seedlings such as paddy rice, beet, vegetable and flower. Further, since the water-soluble adhesive is decomposed by irrigation during seedling raising, this collecting pot is transferred to a grounding type transplanter described in, for example, JP-A-5-308822, and one end thereof is pulled, so that the overlapping continuous The bodies are separated from each other and continuously drawn out, and the seedlings housed in the pots can be continuously planted together with the pots according to the sliding of the transplanter.

[0003]

By the way, in the conventional grounding type transplanter, the plant is drawn out from the collecting pot in one row, but if it can be pulled out in two rows or three rows, it is used once. With this, multiple rows of transplants can be performed, and more efficient planting can be performed. However, the conventional continuous collecting pot has a structure in which one continuous body is alternately folded back to the left and right. Due to a shortage, it became impossible to densely aggregate individual pots with a 1/2 pitch shift, and in reality there was no choice but to abandon the use of such continuous pots.

The present invention has been made in view of the above conventional problems, and an object thereof is to make it possible to draw out a plurality of rows without sacrificing a dense gathering state.

[0005]

In order to achieve the above-mentioned object, the present invention connects a square or hexagonal tubular individual pot body formed by expanding a paper or a thin film such as paper with a connecting piece. In the continuous collecting pot for raising seedlings, the individual pots are folded back so that the individual pots are displaced by 1/2 pitch, and the folded portions are attached with a water-soluble adhesive. The continuous body is formed in a plurality of rows by stacking a plurality of strips of a predetermined length and joining the connecting pieces located at the overlapping ends to each other with a waterproof adhesive. Has an extension portion longer than the width of one side surface of the individual pot body, and folds all or part of the extension portion at the overlapping end or the overlapping end of the strip-shaped pieces to the side surface of the individual pot body. It is configured with a water-soluble adhesive. And are characterized.

In the present invention, the strip is the Japanese Patent Publication No.
As disclosed in Japanese Patent Publication No. 4-28327, a configuration in which an individual pot made of a single thin film is formed by alternately deploying a plurality of divided pieces divided by cutting in opposite directions, or As disclosed in Japanese Patent Publication No. 4-79612, an adhesive is formed of two thin films, and an individual pot is a non-adhesive portion of the two thin films, and a connecting piece is an adhesive formed by bonding two thin films with a water-resistant adhesive. It is also possible to provide each as a section.

The present invention does not specify the material type of the above-mentioned thin film, but it is assumed that a material having corrosion resistance is selected at least during the seedling raising period. This raising period is generally 4
It is around 0 days, but in the case of long onions, onions, etc., 40-
90 days or more. Examples of the material having a resistance to corrosion for about 40 days include, for example, paper in which a preservative or bactericide is applied to or mixed with plant fiber paper, or synthetic fiber paper in which synthetic fiber is mixed with natural pulp, and 40 to 90. As a material having a corrosion resistance of a day or more, for example, a synthetic paper mixed paper is treated with a chemical to increase its wet strength, and a non-corrosive non-woven sheet or natural pulp is treated with the chemical. Examples of the chemically modified paper or synthetic fiber-mixed paper treated with antiseptic agents such as bactericides.

Further, in the present invention, the kind of the above water-soluble adhesive is also arbitrary, for example, polyvinyl alcohol,
It can be selected from chemical synthetic products such as polyacrylic acid and polyethylene oxide, or natural products such as gum arabic, glue and carboxymethyl cellulose. As the water resistant adhesive, a chemical compound such as polyvinyl acetate emulsion, epoxy resin emulsion and hot melt can be used.

In the continuous collecting pot for transplanting seedlings constructed as described above, the elongated portion of the elongated connecting piece is used for joining the overlapping ends of the strips, and moreover, part or all of the elongated portion is folded. By sticking to the side of the individual pots, even if the continuous body is composed of multiple rows, it is possible to densely gather the individual pots with a 1/2 pitch shift.

The individual pots 1 are folded and assembled so as to be displaced by 1/2 pitch, and the folded portions are adhered to each other with a water-soluble adhesive. Here, the connecting piece 2 is formed to have a length of 5 times the width of one side surface of the individual pot body 1, and in the folded back of the continuous bodies 3 and 4, the width of the one side surface of the individual pot body 1 is almost the same as the width thereof. The flat portion 5 of the length is left, and both sides thereof are folded portions 6, and these portions 5 and 6 are joined to the side surface of the individual pot body 1 with a water-soluble adhesive. Also,
At the folded ends of the continuous bodies 3 and 4, the connecting piece 2 is appropriately joined to the side surface of the individual pot body 1 by extending the respective lengths and joining them with a waterproof adhesive 7. It is attached with a water-soluble adhesive. Note that, in FIGS. 1 and 2, in order to facilitate understanding, the layers of the folded back continuous bodies 3 and 4 are shown with a space therebetween.

As shown in FIGS. 3 and 4, each of the continuums 3 and 4 is formed by superposing a plurality of strips 10 each having a predetermined length, and the superposed ends thereof are covered with a water-resistant adhesive 7. Each is formed independently by joining. Strip 1
0 is formed here by a piece of thin film 11 such as paper or paper which has a corrosion resistance. In this case, the portion corresponding to the individual bowl 1 is configured as a cut portion 12 (shown by a thick line) having a plurality of cuts in the longitudinal direction, and the portion corresponding to the connecting piece 2 has no cut. It is configured as a cut portion 13, and the non-cut portion 13 is positioned at the overlapping end. The cut portion 12 is formed by alternately expanding a plurality of divided pieces 14 (FIG. 2) divided by the cut in the opposite directions to form the hexagonal tubular individual pot body 1 described above.
On the other hand, the non-cutting portion 13 has both end portions thereof at the folding portion 13.
By using a, the connecting piece 2 having the flat portion 5 and the folding portion 6 is obtained.

Here, the continuums 3 and 4 are the same as in FIG.
As shown in 4 and 4, the two folded portions 1 of the non-cut portion 13
4 strips 10a, 10b, 10c, 10 which are stacked by changing the vertical direction of 3a and changing the shape of the folded portion 13a at the overlapping end, or changing the horizontal direction of the whole.
With d as one set (unit), the plurality of sets 15A, 15B ...
Are laminated, and the folded-back portions (connecting pieces) 13b at the overlapping ends are joined in the respective groups or between the respective groups with the water-resistant adhesive 7 in a predetermined order. Specifically, each group 1
Strips 10a and 10d, 1 at one end of 5A, 15B ...
0b and 10c are connected to each other and are adjacent to each other 15
Between the other end of A and the other end of the set 15B, the strip 10c is formed.
And 10b, 10c and 10a are connected respectively. Reference numeral 8 in FIG. 4 indicates a portion to which the water-soluble adhesive is applied, and the water-soluble adhesive 8 is provided between the overlapping strips 10 and between the cut portion 12 and the non-cut portion 13. Pasted through.

In the continuous collecting pot constructed as described above, when the laminated body shown in FIGS. 3 and 4 is stretched, the cut portion 12 is enlarged and a large number of individual pots are shown as shown in FIGS. The body 1 expands into a honeycomb shape. When raising seedlings, the individual pots 1 are set in a seedling raising box (not shown) while maintaining the expanded state, and the individual pots 1 are filled with cultivation soil and seeded. Then, after raising the seedlings for a predetermined number of days, the continuous collecting pot is transferred to a transplanter of a two-row drawer type (not shown) either together with the seedling raising box or removed from the seedling raising box and transferred to perform transplantation.
Since the water-soluble adhesive 8 adheres between the folding parts 6 of the connecting piece 2 and between the folding parts 6 and the individual pots 1, the respective adhesion parts are watered during seedling raising. When the continuous bodies 3 and 4 are separated by themselves, one end of the continuous body 3 and 4 is pulled, the folding portion 6 is extended, and the individual pots 1 are continuously drawn out in two rows corresponding to the continuous bodies 3 and 4. , Are transplanted in two rows at intervals of the connecting pieces 2.

In the above-mentioned embodiment, the two folding parts 6 of the connecting piece 2 are attached to the side surface of the individual pot body 1 by changing the vertical direction, so that when the individual pot bodies 1 are unfolded, they are adjacent to each other. The open portion between the divided pieces 14 of the individual pot body 1 is closed by the flat portion 5 and the folding portion 6 of the connecting piece 2 (see FIG. 2), so that the cultivation soil filled in the individual pot body 1 is individually separated. It does not leak from the pot 1. In the present invention, it goes without saying that the two folding parts 6 of the connecting piece 2 may be attached to the side faces of the front and rear individual pot bodies 1 in the same direction. The connecting piece 2 is set to have an appropriate length according to the number of rows of drawers, and the number of folds of the folding portion 6 is also set to be appropriate according to the length.
