In a hydroponic cultivation device consisting of a support chevron panel with a large number of holes and a supply mechanism that supplies nutrient solution etc. to the roots of plants inside the chevron panel, multiple The above-mentioned chevron panels can be moved in series and in the row direction and can be taken out; a lighting device that irradiates light to the plants supported by the chevron panels; and a lighting device that irradiates the plants with light emitted from the lighting device. It is characterized by having a reflective surface that reflects light.

<Example> Hereinafter, a preferred example of the hydroponic cultivation apparatus according to the present invention will be described in detail with reference to the drawings.

FIG. 1 and FIG. 2 are explanatory diagrams conceptually showing the hydroponic cultivation apparatus of this embodiment. As shown in both figures, the chevron panel 1 is provided with a number of holes 2 for supporting plant seedlings so that their roots hang inward. is attached and is movable. Such a chevron panel 1 is made of a foamable synthetic resin such as styrofoam, a ceramic material such as a ceramic plate, or the like. As shown in FIG. 2, a plurality of the chevron-shaped grooves 1 are arranged in series and are movable in the column direction. At this time, in this embodiment, a groove 6 is provided to guide the wheel 3, and a support rod 5 is passed through a support member 4 provided at the upper end of the chevron panel 1 in order to further increase stability. , guiding and supporting the chevron panel 1. Such a mechanism for guiding the chevron-shaped panel 1 is not necessarily necessary. A plurality of rows of the chevron panels 1 as described above are arranged in parallel as shown in FIG. moreover,
In this embodiment, a spraying mechanism is adopted as a supply mechanism for supplying nutrient solution etc. to the roots of plants from inside the chevron panels 1, and spray nozzles 7 are installed at appropriate intervals inside the rows of the chevron panels 1. It is set up. This piping is installed using a false branch piping method, etc. so that the supply pressure to each spray nozzle 7 is uniform.
It is. Note that various mechanisms for supplying the nutrient solution, etc., can be considered, such as one that flows the nutrient solution, etc. from above the chevron panel 1; If so, it is not particularly limited.

Furthermore, in this embodiment, the grooves 6 for guiding the wheels 3 of the chevron-shaped panel 1 described above are arranged so that the nutrient solution accumulated on the floor can be recovered, so that it is very economical. All of the chevron panels 1 arranged in a plurality of rows as described above have reeds in the cultivation chamber 11 that blocks sunlight, and a lighting fixture 8 that supplies constant light to the plants is disposed on the ceiling. The wall material of this cultivation room 11 is not particularly limited, but if necessary, a heat insulating material may be used. In addition, a sodium lamp, a mercury lamp, etc. are used as lighting equipment. Since plants are grown using only such artificial light, uniform plants can be cultivated in a planned manner. In such equipment, it is necessary to effectively use the light emitted from the lighting fixtures 8 to reduce the number of lighting fixtures 8, and to significantly reduce electricity costs and the like to improve economic efficiency. In this embodiment, a reflector 9 is installed on the ceiling as a reflective surface that reflects the light emitted from the lighting fixture 8 toward the plants, and a reflector 10 is installed on the surface of the chevron panel 1 to greatly increase economic efficiency. It has improved significantly. The reflectors 9 and 10 used here are not particularly limited as long as they reflect light, such as a SUS plate or aluminum foil. Furthermore, the chevron panel 1 and the like may be made of the reflector itself, such as a SUS plate.

The operation of the apparatus configured as described above will be explained together with the mode of operation. First, seedlings of plants such as leafy vegetables such as Okayama salad greens, bipretuce, summer green, and red fire are inserted into the holes 2 of the chevron panel 1. Then, a predetermined light is emitted from the lighting device 8, and I! By spraying a predetermined amount of the nutrient solution through the Jt fog nozzle 7, the seedlings are grown in a planned manner and are harvested as plants of approximately uniform size. In this embodiment, the chevron panels 1 are arranged in series and are movable and removable, so that, for example, a chevron panel 1 lined with new seedlings is inserted from one end of the row, and the chevron panels 1 are sequentially fed in one direction. By taking out the plants that have grown to a point along with the chevron panel 1, work efficiency can be greatly improved. In other words, if it takes 20 days to harvest plants, for example, if 20 chevron panels 1 are lined up in a row and moved in one direction by one panel per day, the chevron panels 1 will enter from one end. Since it takes 20 days for the other end to emerge, the plants on the chevron panel l will have grown sufficiently during this time. Therefore, this method greatly improves work efficiency and allows regular harvesting. At this time, pushing the chevron panels 1 by hand is sufficient, but if the number of panels K increases, a drive device may be used. By moving the chevron panel 1 in this manner, in addition to the effect of improving work efficiency, it is possible to obtain the effect of keeping the irradiation conditions (amount, direction) and nutrient solution supply conditions approximately constant.

FIG. 3 is an explanatory diagram conceptually showing a hydroponic cultivation factory using the above-described apparatus. This factory has a structure that blocks sunlight), and lighting equipment is installed inside the factory. Also, as shown in the drawing, a row of one chevron panel 1 is one
There are 12 rows of reeds from 01 to 112, and these chevron-shaped panels l can be moved in the direction of the seat in the drawing by a driving force. In addition, there are holes 2 of these chevron panels 1 in the same factory.
A seedling nursery room 120 for growing seedlings is installed, and a sterilization tank 121 and an underground tank 122 for nutrient solution are arranged side by side. Further, spray nozzles 7 are fixedly installed inside the rows of chevron-shaped panels 1, and these are piped to a separately installed nutrient solution M sterilization tank 125 pressure tank 124 and an underground stock tank 123. The nutrient solution is periodically sprayed through these spray nozzles 7, and the nutrient solution accumulated on the floor is collected through the grooves 6. The seedlings grown in such a factory and in the Seedling Z12O are
After being inserted into the hole 2 of the panel 1, it is attached to the stone side of the row of chevron panels 1 in the figure. These seedlings are periodically sent to the left in the figure along with the Yamagata panel 1, and the CO2 in the atmosphere is removed.
They grow by being fed nutrient solution and artificial light while absorbing 02.

and.

When reaching the left end of the row, the leaves should be moved so that they grow sufficiently and uniformly. The thus-arranged plants are removed in rows together with the chevron panels 1, and collected at the Hanel assembly area 128 by the panel moving conveyor 126. There, the plants are harvested, sorted by a sorting conveyor 127, automatically packaged and boxed, and then shipped. Also, the empty chevron panel 1 is sent to the right in the drawing by the return conveyor 113, and new seedlings are arranged again.

As explained above, by installing the apparatus according to the present invention, the work can be carried out only at both sides of the factory (on the left and right side in the figure), making it very efficient. Furthermore, plants can be shipped regularly and in a planned manner, which is even more effective.

<Effects of the Invention> As described above in detail with the examples, the hydroponic cultivation apparatus according to the present invention can provide the following effects.

b) A cultivation room that blocks sunlight is installed, and cultivation is performed using only artificial light without using sunlight, so the pots have a uniform thickness of δ.
of plants can be harvested systematically.

By arranging the chevron panels in series and making them movable and removable, work efficiency during seedling introduction and harvesting can be greatly improved. Furthermore, by periodically moving the chevron panels in one direction, the irradiation conditions and nutrient solution supply conditions become constant, allowing for a more systematic harvest with uniform grains.

No. 9 It is recommended to provide reflective surfaces on the inner surfaces of the ceiling, walls, floors, etc. of the cultivation room, as well as on the surface of the chevron panels. This makes it possible to effectively use artificial light, reducing the number of lighting equipment and reducing costs such as electricity bills. can be drastically reduced, and economic efficiency is greatly improved.

Furthermore, as shown in the example, if a groove is provided to guide the movement of the chevron panel, it can also serve the function of collecting the nutrient solution that is supplied to the groove and accumulated on the floor, thereby reducing equipment costs. Furthermore, it is economical because it saves on nutrient solution.
