[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a collective incubator for transplanting seedlings, and more particularly to an improvement in a polystyrene foam incubator.

[0002]

2. Description of the Related Art Conventionally, a collective seedling incubator made of hard plastic or styrofoam divided vertically and horizontally is filled with soil, sowed with vegetable seeds, planted with cuttings of flowering seedlings, and placed in a greenhouse. It is widely used to grow in, for example, and transplant it to a field as an adult seedling. When transplanting adult seedlings grown in these seedling raising plants to a field, general vegetables and flowers are pulled out of the seedling raising devices by hand or machine and planted.

When growing seedlings of vegetables in a greenhouse or the like as described above, if a collective seedling incubator made of styrofoam is used, this seedling incubator is made by expanding and expanding plastic particles several tens of times. Due to the structure, there are minute cracks on the inner peripheral surface of the pot portion, and the roots of the seedlings that have gradually grown may enter into the cracks. In this case, the roots of the seedlings are naturally cut off at the time of transplantation, the inner peripheral surface of the pot portion is damaged, and the life of the collective seedling incubator itself is shortened.
As a preventive measure, there has been a collective incubator made of thin-walled hard plastic, which is made of a material much harder than Styrofoam and is used by fitting it from above to a collective incubator made of Styrofoam.

However, in this method, there is a problem in that the expansion rate and the shrinkage rate differ between the styrofoam collective incubator and the thin-walled hard plastic collective incubator because of their different quality due to their aging. There have been problems such as the formation of a gap between the two, and the disintegration of the thin-walled hard plastic incubator. When such a problem occurs, the pot portion of the thin-walled hard plastic collective incubator is tilted due to gaps and distortion, so that the seedlings also tilt and the growth directions are different. In addition, the collective seedling incubator made of thin hard plastic remains distorted, and cannot be reused.

[0005]

SUMMARY OF THE INVENTION In view of the above, the present invention is intended to prevent a thin and rigid plastic incubator from being distorted.

[0006]

The configuration of the present invention for eliminating such a problem will be described with reference to the drawings. A thin-walled hard plastic collection in which a plurality of pot portions 3 have the same inner shape and arrangement in a styrofoam collective incubator 5 having a plurality of pot portions 3 on the upper surface.
All pot portions 3 of the seedling incubator 4 are fitted with each other.
Of transplanting seedlings to be used in a stacked form from above
In the seedling incubator , a thin rigid plastic collective incubator
4. A collective seedling incubator for transplanting seedlings, characterized in that one or more convex folds 1 were formed in both the longitudinal and horizontal directions on the connecting surface 2 connecting the pots 3 of 4 .

The required number of folds 1 may be determined as appropriate depending on the size of the styrofoam collective seedling incubator 5 to be used, the size and number of the pots 3 and the like. In the drawings, the thickness of the fold 1 is exaggerated for easy understanding. Reference numeral 6 denotes a drain hole of the pot portion 3.

[0008]

Thus, the thin-walled hard plastic collective incubator 4 overlaps with the styrofoam collective incubator 5, and the folds 1 at various places higher than the connecting surface 2 are shrunk or expanded. By automatically adjusting the opening / closing degree and the height of the two legs, which are the lower ends of the folds 1, the entire expansion and contraction can be absorbed, so that there is no distortion.

[0009]

Embodiments of the present invention will be described below. In general, the method of manufacturing the thin and rigid plastic incubator 4 divided vertically and horizontally is to blow a plastic such as vinyl chloride, polystyrene, or polyethylene, which is a material melted at a high temperature, into a mold. In the present invention, the fold 1 is also formed on this mold (not shown). Although the collective seedling incubator 4 made of thin hard plastic is drawn thicker in the drawing, the thickness may be about 0.5 mm. The convex shape of the fold 1 is preferably a triangular cross section as shown in the figure because it is easy to bend, but the upper portion may be semicircular, and the height of the collective seedling incubator 4 made of a thin-walled hard plastic is the whole. The size may be determined according to the size, etc., and these are design problems.

As can be seen from FIG. 1, the intersection of the vertical and horizontal folds 1 is notched, but such an arrangement is preferable because of its flexibility. The thin-walled hard plastic plastic seedling incubator 4 is fitted to a separately manufactured styrofoam collective seedling incubator 5 for use. Usually, the two are adhered to each other with an adhesive.
Put the soil in the pot part 3 of the combination,
Here, seeds such as vegetables are sown and grown in a greenhouse.

[0011]

[Effects of the Invention] Even when the stacked seedling incubators shrink or expand due to changes in temperature and humidity during storage and use of the seedling incubators, the fold 1 expands and contracts. The difference in shrinkage and expansion can be absorbed, so that the thin and rigid plastic incubator 4 is not distorted.
