The present invention relates to an automatic nutrient solution supply device, and more particularly, to an apparatus for automatically supplying nutrient solution when hydroponicly cultivating plants such as fruit, leafy vegetables and flowers.

In the conventional nutrient solution supply apparatus, there was a continuous mixed feeding type and a batch type of FIG. 2 as shown in FIG. 1, but the continuous mixing and feeding type of FIG. The sensor (2) and the water level control sensor (3) for detecting (PH) and concentration (EC) are built in. The mixing tank 1 is connected to the raw water tank 4 and the pipe 5, and the raw water pump 6 for pumping the water of the raw water tank 4 is connected to the pipe 5. The circulation supply pipe (7) is connected to the lower side of the mixing tank (4), which is connected to the upper and lower sides, the acid tank (8), the AI liquid tank (9) and the non-liquid tank (10) to the circulation supply pipe (7). ) And pipes (11) (12) (13).

The filter (14) (15) (16) and the liquid pump (17) (18) (19) and the electrons between the tubes (11) (12) (13) and the tanks (8) (9) (10). The valves 20, 21 and 22 are connected to each other.

The circulating supply pipe 7 is connected to the supply pump 23 and the filter 24, and to the supply pipe 25 for supplying the nutrient solution to the medium, which is connected to the pressure gauge 26 and the solenoid valve 27. It is. Reference numeral 28 in the drawing denotes a central control system for controlling the nutrient solution and the like of the nutrient solution supply device.

The nutrient supply device as described above supplies the water from the raw water tank 4 to the mixing tank 1 by the raw water pump 6 and at the same time the acid tanks 8 and A by the liquid fertilizer pumps 17, 18, and 19. It is mixed with the raw water of the liquid tank 9 and the non-liquid tank 10, and is supplied to the medium via the supply pump 23 and the filter 24, and then through the supply pipe 25.

The raw water and the component liquid are mixed and supplied in the range of a and b points of the water level control sensor 3 installed in the mixing tank 1.

In the A liquid tank 9, ammonium nitrate, calcium nitrate and potassium nitrate are mainly stored, and in the non-liquid tank 10, ammonium nitrate, magnesium sulfate, first ammonium phosphate, first potassium phosphate, potassium nitrate, potassium sulfate, Manganese sulfate, boron, zinc sulfate, copper sulfate, and sodium molybdate are mainly stored. However, their proportions and types may vary depending on the type and growth time of the plant.

The conventional continuous mixed feed nutrient solution as described above has a drawback that cannot be used because the feeding time and the mixing time do not match when the plant cultivation area becomes large. As another example, when the nutrient solution is supplied to the above apparatus installed for strawberry cultivation, and other crops are cultivated, the growing time is different (because it is longer), so that the mixing time is not correct (cap). will be.

Referring to the related art according to FIG. 2, the upper and lower widths of the sensors a and b points for detecting the upper and lower limits of the water level among the water level control detecting sensor 3 built in the mixing tank 1 are increased and mixed. Batch type has been proposed in which the capacity of the tank 1 is increased to supply it after complete mixing.

In the apparatus, the same reference numerals as those in FIG. 1 denote the same members.

In the batch type nutrient supply device according to FIG. 2, a large amount of raw water and a fertilizer component must be mixed and supplied, and thus, the exact ratio cannot be adjusted. Especially in the nursery period, the mixing ratio is exactly required, but this is not met.

In addition, when the automatic mixing device by the central control system 28 is broken, it is necessary to manually mix and supply, followed by hassle and inconvenience.

That is, in the apparatus according to FIG. 2, since the capacity of the mixing tank 1 is designed to be small, continuous manual operation is required.

In addition, in the nutrient solution supply device according to the prior art 1 and 2, the pipes (11) (12) (13) connected between the mixing tank (1), the AI liquid tank (9) and the non-liquid tank (10) It was connected immediately or had a connection structure as shown in FIG.

That is, as shown in FIG. 3, liquid-liquid pumps 29 and 30 were used exclusively for the AI-liquid tank 9 and the non-liquid tank 10, respectively.

In this case, since there is a pumping error between the liquid-liquid pump 29 of the liquid-liquid tank 6 and the liquid-liquid pump 30 of the liquid-liquid tank 10, it cannot supply in an exact ratio.

In particular, as time goes by, the error rate becomes larger, and thus the plant cannot supply the precise nutrition necessary for growth.

Therefore, the object of the present invention was devised to solve the conventional problems as described above, the plant is required while having both a function according to the continuous mixing feed type and a function according to the batch type (feeding type after mixing). It provides a nutrient solution automatic supply device that can accurately mix the ingredients.
