Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hydroponic cultivation apparatus suitable for cultivating various kinds of flowers and vegetables at home.

[0002]

2. Description of the Related Art A device for performing hydroponic cultivation while gently raising and lowering a large number of planter pallets inside a greenhouse has been widely known. However, such a conventional hydroponic cultivation apparatus has a structure in which liquid fertilizer is sprayed from the top surface or the bottom surface of each planter pallet, so that a system for dispersing and supplying the prepared liquid fertilizer to a large number of spray heads is required. In addition, there is a drawback that a part of the sprayed liquid fertilizer falls on the plant cultivated on the planter pallet and stains the plant.

[0003]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems of the prior art, and is capable of reliably supplying liquid fertilizer to each planter pallet with a simple structure, and liquid fertilizer drops from the upper planter pallet. It is made in order to provide a hydroponic cultivation apparatus that does not have a risk of soiling the plant on the lower planter pallet.

[0004]

A hydroponic cultivation apparatus of the present invention made to solve the above-mentioned problems is constructed by vertically arranging a frame having sprockets vertically inside a greenhouse at predetermined intervals. The planter pallet was horizontally supported between the chains provided between the sprockets to intermittently move up and down, and the bottom of the greenhouse was provided with a liquid fertilizer immersion water tank in which the bottom of the planter pallet lowered to the lowest position was immersed. It is a feature.

[0005]

In the hydroponic cultivation apparatus of the present invention, when the planter pallet, which is supported by the chain and is intermittently moved up and down, is lowered to the lowest position, the bottom thereof is immersed in the liquid fertilizer immersion water tank, and the liquid fertilizer is on the bottom surface of the planter pallet. Absorbed from. This immersion time can be strictly controlled depending on the type of plant to be cultivated. Further, according to the present invention, since the liquid fertilizer-immersed water tank is provided at the bottom of the greenhouse, it is not necessary to provide a system for disperse the prepared liquid fertilizer to a large number of spray heads, which simplifies the equipment. You can Further, according to the present invention, since liquid fertilizer is not sprayed as in the conventional case, a part of the sprayed liquid fertilizer does not drop on the plant on the lower side and pollute the plant.

[0006]

The present invention will be described below in more detail with reference to the illustrated embodiments. In FIGS. 1 and 2, reference numeral 1 is a greenhouse having a height of about 2.5 m capable of controlling temperature, humidity and the like, and 2 is a frame installed therein at a predetermined interval. In this embodiment, four (2 pairs) frames 2 are erected, but two (1 pair) frames may be installed.

Sprockets 3 and 4 are provided on the upper and lower portions of each frame 2, respectively. The upper sprocket 3 is attached to the frame 2 by a short shaft (not shown). As shown in FIG. 1, two lower sprockets 4 are provided at the same height, and one of them is attached to a drive shaft 5 extending between the frames 2 and 2. A drive sprocket 6 is driven by an appropriate drive means such as a motor, and has a structure in which the drive shaft 5 can be intermittently driven by the chain 7.

Endless chains 8 and 8 are stretched between the sprockets 3 and 4, and a large number of planter pallets 9 are horizontally supported between the chains 8 and 8. These planter pallets 9 are moved up and down intermittently at a slow speed of, for example, about 50 mm per minute. The stop time varies depending on the type of plant to be cultivated, but is about 10 seconds, for example. A large number of through holes for absorbing liquid fertilizer are formed on the bottom surface of each planter pallet 9.

A liquid fertilizer immersion water tank 10 is provided at the bottom of the greenhouse 1. The liquid fertilizer immersion water tank 10 is installed between the paired frames 2 and 2, and the bottom of the planter pallet 9 lowered to the lowest position is immersed as shown in the figure. The liquid fertilizer immersion water tank 10 is supplied with the liquid fertilizer prepared according to the plant, and is absorbed from the through hole at the bottom of the planter pallet 9. The amount of absorption can be controlled by the stop time of the planter pallet 9. In addition, a large number of water sprinkling nozzles 11 are installed inside the greenhouse 1 so that water can be sprinkled during the stoppage of the intermittently driven planter pallet 9. This sprinkling amount can also be automatically controlled.

The hydroponic cultivation apparatus of the present invention comprises various kinds of flowers,
Orchids, mountains, herbs, foliage plants, vegetables, small root vegetables, etc. can be cultivated on the planter pallet 9, and temperature, humidity, ventilation, sunshine, etc. are controlled according to the growth conditions. In addition, by controlling the amount of liquid fertilizer supplied by the liquid fertilizer immersion water tank 10 and the amount of water sprayed by the water spray nozzle 11, anyone can easily enjoy hydroponics.

When a total of 16 planter pallets 9 are provided as in the embodiment, for example, if kaiware radish, salad vegetables, radish, sprouts, radish radish, etc. that can be collected within 16 days are cultivated, One pallet worth of harvest can be obtained. In addition, if flowers are cultivated alternately for a flowering period of 1 week and a growing period of about 4 weeks, flowering can be enjoyed every week. In this example, plants having a plant height of about 25 cm can be cultivated, so that it becomes possible to put rapeseed, trifoliate, garland chrysanthemum, lettuce, small turnip, spinach, radish, etc. on the table every day.

[0012]

As described above, according to the hydroponic cultivation apparatus of the present invention, various plants can be hydroponically grown, and when the planter pallet descends to the lowest position, it absorbs liquid fertilizer from its bottom. Can be made. For this reason, it is not necessary to provide a system for supplying the prepared liquid fertilizer to a large number of spray heads in a distributed manner as in the conventional case, and the equipment can be simplified. Further, according to the present invention, since the liquid fertilizer is not sprayed as in the conventional case, the sprayed liquid fertilizer does not stain the plants on the lower side. Therefore, the present invention is highly valuable as a hydroponic cultivation apparatus that solves the conventional problems.
