Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to plant cultivation, and particularly relates to a hydroponic cultivation device suitable for reducing nutrient water consumption and at the same time facilitating the movement of plants.

[Background of the idea]

A plan view of a conventional hydroponic cultivation device is shown in Figure 1.
The sectional view taken along the line A-A in the figure is shown in Fig. 2, and the sectional view taken along the line B-B in Fig. 2 is shown in Fig. 2.
A cross-sectional view is shown in FIG. The supports 2 are arranged on top of the cultivation tank 1, and a large number of plants 4 are planted on the culture bed 3. is cultivated by soaking. The cultivated plants 4 are at various stages from planting to harvesting, and are shown as young seedlings 4a, medium seedlings 4b, and mature plants 4c in FIGS. 1 to 3.

In hydroponic cultivation, it is desirable to easily move the plants 4 according to their growth to provide optimal environmental conditions according to the growth of the plants 4, but there is a method for easily moving the support plate 2. There was no such thing, so they were moved using conveyor belts. However, if moving equipment is made cheap or not provided, there is a problem in that labor costs are high. If you move plants 4 with emphasis on environmental conditions in this way, the moving equipment costs and labor costs will be high, but if you reduce the moving equipment costs and personnel costs, it will be difficult to change the environmental conditions, and you can expect the optimal growth of plants 4. The drawback was that there was no. Furthermore, the difficulty in moving the plants 4 means that the operator has to travel long distances for planting and harvesting, resulting in a disadvantage in that work efficiency is reduced.

Furthermore, in the conventional hydroponic cultivation apparatus, as shown in FIGS. 1 to 3, the lower part of the roots of the culture bed 3 and plants 4 is immersed in the nutrient water 5.
There was only nutrient water that rose above the roots due to capillary action, and the nutrient water supplied above the roots of plant 4 was not in the best condition.
In other words, the nutrient water rising above the roots of plant 4 is
Since only what was absorbed by the plants 4 or vaporized into the air remained, the nutrient water was extremely susceptible to deterioration. For this reason, there was a drawback that the upper part of the roots of the plants 4 turned brown as the nutrient water deteriorated, and the roots eventually became rotten. It is very important to supply oxygen to the roots of plant 4, but if only the top of the culture bed 3 and the roots of plant 4 are exposed to air, the roots of plant 4 will not be under the best management. I couldn't stop.

[Purpose of invention]

An object of the present invention is to provide a hydroponic cultivation device that allows plants to be easily moved.

[Summary of the idea]
