Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a plant cultivation device for moving plants while expanding the spacing between plants during plant cultivation, from planting to harvesting.

"Prior Art" In plant cultivation, in order to maximize plant growth and obtain maximum yield, it is necessary to maintain appropriate plant spacing depending on the growth stage of the plant. If they are planted too densely, diseases will occur more easily, resulting in poor growth and lower yields. On the other hand, if the appropriate spacing between plants is maintained at the time of planting, which is the same as that at the time of harvesting, the cultivation area efficiency at the initial stage of cultivation will be low, and a large area will be required for the greenhouse, which will be uneconomical. For this reason, a plant cultivation device that increases the spacing between plants by moving the plant planting pots circularly or radially from the center of the cultivation tank according to the growth stage of the plants, or expands the spacing between the plant planting pots from the planting side to the harvesting side. A plant cultivation device has been proposed in which the cultivated area is made rectangular by moving the cultivated area while moving the cultivated area so that the cultivated surfaces thereof face each other.

A method has also been proposed in which the plant planting pot is turned over using a rotary in half the number of days required from planting to harvesting.

``Problems to be Solved by the Invention'' The above-mentioned plant cultivation apparatus, which adjusts the distance between plants according to the growth stage of the plant without requiring any human labor, has the following drawbacks. If the cultivation equipment has a special shape such as a circle, there will be wasted space in the greenhouse that is not related to cultivation, and it will also cause problems with the installation of the cultivation equipment and the layout of the greenhouse, making it difficult to increase the cultivation area. You can't expect much of an effect.

In addition, when moving cultivation from planting to harvest with the cultivation surfaces facing each other, the cultivation equipment becomes longer, and the planting and harvesting areas are on opposite sides, creating work space on both sides of the planting and harvesting sides. Not only is this necessary, but it also causes problems in workability.

If you use a rotary to turn back in half the number of days required from planting to harvest, the rotary is expensive, and the optimal plant spacing is usually different in the first half and second half of the required number of days. , there is wasted space on the first half side,
Space cannot be used effectively.

"Means for Solving the Problems" In order to eliminate the above-mentioned drawbacks, the present invention provides a plant cultivation device that moves the planting pots by increasing the distance between the planting pots as the plants grow from planting to harvest. A folding mechanism is provided at an intermediate position of the total moving distance from to harvesting, and the planting pot is configured to be folded back by the folding mechanism.

``Function'' With this structure, the plant planting pot is turned back at the midpoint of the total travel distance from planting to harvest, so the shape of the cultivation device can be made rectangular while maintaining the optimum plant spacing. can.
Therefore, it is possible to simultaneously increase the yield and improve the efficiency of the cultivation area.

"Example" Figure 1 is a schematic plan view of the plant cultivation device of the present invention.
Figures 2, 3, 4 and 5 are CD sectional view, BA sectional view, AD sectional view, and BC sectional view of Figure 1, respectively.
FIG.

In the figure, 1 is the planting point, 2 is the harvesting point,
3 and 3a are the turning points. 4 is a rail, and a plant planting pot 5 is placed on this rail 4. The plant planting pot 5 is planted at the planting point 1 and moves on the rail 4. The moving distance of the plant planting pots 5 on the rails 4 is such that the pitch becomes wider according to growth (number of days after planting), and the distance between the rails 4 grows in the direction perpendicular to the movement direction (number of days after planting). It is becoming wider depending on the The plant planting pot 5 moves on the rail 4 until it reaches the turning point 3. FIG. 4 shows how the plant planting pot 5 is moved from the planting point 1 to the turning point 3.

Each plant planting pot 5 may be moved by tilting the rail 4 during movement, providing a stopper and using it as a stop, or by using a motor.
At the turning point 3, the plant planting pot 5 is moved to the turning point 3a side by the turning mechanism 6. FIG. 3 is a cross-sectional view of BA, which is one step before turning back point 3, at the middle position of the total travel distance to planting point 2, and the spacing between each plant planting pot 5 is almost the same. FIG. 6 shows an embodiment of the folding mechanism 6, in which a pushing mechanism (not shown) moves the plant planting pot 5 placed on the roller 6a and the belt conveyor 6b by a predetermined distance and places it on the rail 4 again. It consists of

The plant planting pot 5, which has been moved onto the rail 4 on the turning point 3a side, moves toward the harvesting point 2 in the same manner as when heading from the planting point 1 to the turning point 3. In addition, although the rail 4 was used to move the plant planting pot 5 in the above embodiment, a guide groove or the like may also be used. When this plant cultivation device is applied to hydroponic cultivation using artificial light, it is possible to perform daily harvest production without disrupting planned cultivation.

"Effects of the invention" According to the invention, the intervals between plant planting pots can be maintained at optimal intervals according to growth, and the cultivation area can be made rectangular, so the cultivation area efficiency is dramatically improved. Moreover, compared to the conventionally proposed plant cultivation equipment that gradually spreads the plants from the planting side to the harvesting side, and has the moving surfaces facing each other and does not have a mechanism to fold back halfway, it is easier to work in a greenhouse (planting and harvesting is easier). It has the advantages of a greenhouse layout (it can be done in the same space) and a greenhouse layout (it is half the length of conventional cultivation equipment and can be rectangular in shape).
