Description

The invention relates to agriculture and can be used for growing plants by the method of hydroponics.

The aim of the invention is to increase the rhythm of flooding. The drawing shows the installation diagram.

The automatic plant for growing plants contains vegetative vessels 1, communicating with the main tank 2 for the feed liquid through the drain pipe 3, the hydraulic lock in the form of a stopper 4 and the ascending tube 5 with the outlet 6, an additional tank 7 connected by pipe 8 to the float valve 9, located in the water-measuring chamber 10 mounted on the drain pipe 3. The reservoir 2 for the feed liquid is provided with a compressed air supply pipe 11. In the vegetation 1

The installation works as follows.

The valve 13 is opened, and the nutrient solution fills the main reservoir 2 for the supply liquid and through the outlet 6 - shut-off tank 4. The filling continues until the float valve 9 closes. Thereafter, a small stream of compressed air is fed through the nozzle 11, displacing the solution from the reservoir 2 into vegetative vessels 1. At the same time, the root system of the plants is under water. At the same time, the fluid in that part of the valve will shut down

tank 4, which is connected to the upper part of reservoir 2. The column-liquid in the ascending tube 5 increases in accordance with the increase in the level of 5 liquids in the drain pipe 3 and then in the vegetation vessel 1. When the air pressure in the reservoir 2 exceeds the level of lifting of the liquid, determined by the height of the hydraulic lock, ejects the liquid from the stop tank 4 and the east tube 5 into the growing pot 1. The pressure in reservoir 2 drops to atmospheric,

5 as the incoming compressed air freely comes out. In this case, the nutrient solution flows through the drain pipe into the tank 2 before filling through the outlet 6 of the stopper 4

.10 hydraulic lock, after which the cycle is repeated.

When the circulating volume of the nutrient solution decreases due to water loss for transpiration and evaporation, when the fluid from the vegetation vessel 1 is completely discharged, the fluid level in the water chamber 10 decreases, which leads to the opening of the float valve 9 and automatic replenishment of the nutrient solution from the additional tank 7.

A water meter chamber is needed to prevent circulating

, - through the discharge pipe 3 of the fluid flow for the operation of the float valve 9. The V-shaped tube of the stopper 4 and the ascending tube 5 must be narrow enough to ensure

Q complete discharge of fluid from them. The cycle time is controlled by varying the compressed air feed rate. The pressure of compressed air in its line should slightly exceed the maximum pressure of the liquid column in the hydraulic assembly.
