Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic aeration method in hydroponic cultivation.

Conventional hydroponic cultivation methods include the pentieri tube method, the erected hydroponic method, and the forced compressed tuna hydroponic method. However, in the conventional methods described above, the equipment is complicated and expensive, and the amount of air ([1A) mixed into the cultivation water is likely to be too much or too little. Therefore, it is difficult to create favorable plant growing conditions. I can not say.

The present invention has been made to overcome the drawbacks of the conventional devices as described above, and the device has a simple configuration and can be manufactured at low cost. To provide an automatic air mixing method in hydroponic cultivation that improves conditions for growing other substances by automatically and effectively mixing air into cultivation water after the supply of enemies.

The present invention will be described below in detail based on drawings showing one embodiment. In Figure 0, 1 is a cultivation tank (bed) made of foamed steel or the like, and the cultivation water stored in this cultivation tank 1 is A cultivation bed 3 made of foamed steel or the like is floating on top of the cultivation bed 2. A large number of tags 4 are open on the cultivation bed 3, and a water-absorbing planting bed 5 such as a sponge is embedded in the holes 4 as well. 6, the seeds that have arrived on the shingomebo 5 have germinated and grown, and the roots 6a are extending into the cultivation water 2.

A water suction pipe 7 is connected to the paper part of the upper tank 1, and the water pipe 7 is connected to the suction port of the pump 8. - 10,000, a water pipe 9 is installed at the discharge port of the pump 8, and this water pipe 9
A water discharge pipe 10 connected to the water pipe 10 is installed in the vicinity of the upper wall. A number of water discharge holes 10JI are opened above the water discharge vlO, and the outer layer of the pipe is closed.
lb is a water-stop pulp, and 12 is a drain pipe provided with an opening/closing pulp 121. With this configuration, when the p1 pump 8 is driven, the cultivation water 2 in the
It is possible to absorb water from the water pipe 9 and return it from the water pipe 10 to the fishing layer 1.

A water tank 14 is separately connected to the upper ml water pipe 7 via a conduit 13. A fertilizer side 15 is housed within this tank 14. 16 is a timer for determining the operating time of the pump 8.

Next, *@Ming's automatic air mixing method will be explained. By operating the pump 8, the cultivation water 2 in the coral tank 1 flows from the water suction pipe 7 *7
XL, in the one that connects back into 4111 from the water discharge pipe IO via the water supply pipe 9.

The enemy 15 in the II'#IL tank 14 mixes into the cultivation water 2 in the water pipe 7 through the pump 8, and this mixed water is discharged into the tank 44111 and becomes fertilizer for the crops 6. When the 511 liquid 15 in the tank 14 eventually becomes empty, the metal in the tank 14 is subsequently sucked in by the pump 8 and flows into the suction pipe 7. That is, air is mixed into the mixed water in the water suction pipe 7, and the water is discharged through the water supply pipe 9't- to the water discharge hole 1 in the water supply pipe 9't-.
#1 in air bubbles changes from 0a to 1 and enters the cultivation water in Nene 1.
A total of votes are collected. Air is supplied from the tank 14 by setting the timer 16 to 111ml. The amount of oxygen supplied to the cultivation water 2 in the paddle 1 can be determined by setting the operating time of the pump 8. Note that when the pump 8 stops after the set time of the timer 16 has elapsed, the water level of the cultivation water in the water suction pipe 7 will rise through the conduit 13 in the tank 14, so there will be no support for the next pump operation. To drain water from the drain pipe 1, if the pulp 1lb is closed and the pump 8 is operated, water can be absorbed from the water suction pipe 7 and 9 gm of water 2 can be discharged from the drain pipe 12 to the outside.

In the present invention, since the operation time of the pump 8 that introduces air from the tank 14 is set by the timer 16,
The amount of air supplied to the cultivation water can be arbitrarily adjusted depending on the amount of water in the cultivation tank 1 and the amount of crops 6, so that crops can be grown under optimal conditions.

That's it! As explained above, according to the present invention, the cultivation water of Cultivation J@Hinai is circulated (using a pump), and the OX liquid is mixed into the circulating water from a separate nutrient solution tank, and the plate in the tank is When the water becomes oxidized, the air in the evening is introduced into the cypress water using a pump to mix air into the water that is being cultivated. By supplying nutrient solution and mixing in an appropriate amount of air, effective cultivation can be carried out under suitable hydroponic conditions. Furthermore, since the device is simple, it can be manufactured at low cost and can be installed in any location.Furthermore, the present invention has the advantage that it can be widely applied to all kinds of crops that can be grown hydroponically.
