The invention relates to the reclamation, in particular irrigated agriculture.

A device for automatic irrigation, including the supply tank mounted it on the mark trabotivishte cyclically at regular intervals of time and does not depend on weather conditions.

Know another device for automatic irrigation (watering), adopted as a prototype, including the supply tank is installed in it at the level of operation of the siphon, filter capacity, mounted on the hinge and fixed in the original position by a latch controlled evaporation tray /2/.

Inclusion in the irrigation of this device depends on weather conditions, but it may be involved in the work automatically only once.

The figure schematically shows the proposed device for automatic irrigation.

Automatic irrigation contains the supply tank 1, which is set to trigger the siphon 2, output 3 from the supply tank connected with the irrigation system. On the supply tank 1 is installed on the hinge starting tank 4 and the evaporation tray 5. Starting capacity of 4 fixed in the initial position by the latch 6. In addition, over the supply tank 1 set supply line 7, which is associated shut-off float valve 8. Starting the tank 4 is equipped with a drive return to its original position, for example, by means of a spring 9. On the evaporation tray 5 is rigidly fixed to the latch 11, at the other end of the counterweight 12 with adjustable position. In addition, the evaporation tray 5 is equipped with overflow pipe 13 with a height-adjustable overflow. Above the shut-off float valve 8 in the supply line 7 installed valves: 14 to supply water to the supply tank 1; 15 - to supply water to the starting capacity of 4.

In the initial position, the float valve 8 closes off the water supply to the actuator capacitance 4 and the supply tank 1. Evaporative tray 5 under the weight of the water and the attraction of a magnetic latch 11 is fixed in the initial position. The starting capacity is fixed in the initial position by the latch 6.

The device operates as follows. When hot period begins with the evaporation of water in the evaporator 5, which leads to the reduction of its quantity in the evaporation vessel 5, and at a certain moment is detached from the magnet 11 and the rapid rotation of the tray 5 around the axis due to the load 12. The evaporator 5 by its lever 10 acts on the latch 6 and releases the starting capacity of 4. Starting the container 4 is rotated around an axis that is offset from the center of gravity, and the water within it, is poured into the evaporator 5 and the supply tank 1. Evaporative tray 5 under the influence of the weight of the Starting capacity of 4, freed from water by means of the actuator 9 is returned to its original position and latch 6.

The sharp rise of water in the supply tank 1 includes a siphon 2 and starts irrigation through the pipeline 3.

The lowering of the water level in the supply tank 1 causes the float valve 8, and the water from the supply line 7 through the valve 14 flows into the supply tank 1 and through the valve 15 in the starting capacity 4. After lowering the water level in the supply tank below the intake tube of the siphon 2 irrigation is stopped, and the incoming water through the valve 14 fills the supply tank 1, as the float valve 8 is open. Once the water level reaches the specified level, the float valve 8 closes off the water flow from the pipe to the valves 14 and 15. The excess water is necessary for the safe return of the evaporator 5 to the initial position, through the drain tube 13 is poured into the supply tank 1. The remaining amount of water in the evaporator provides a specified period of time between watering. The entire system is returned to its original state and ready for the next irrigation cycle after a specified period of time.

The device takes into account the status is sustained fashion the tray 5, will add to the amount of water in it, and over through the drain tube 13 will result in the supply tank. Since the rate of flow of water in the supply tank is small, it will not trigger the operation of the siphon.

The device gives the possibility to adjust the watering time due to the amount of water flowing through the valve 14:

T=Q/(W1-W2)

where T - time irrigation;

Q - capacity of the supply tank, l;

W1- the amount of water flowing in the supply tank, l/min;

W2- the amount of water flowing in the irrigation system, l/min
