Abstract

The invention relates to agriculture and can be applied when irrigating agricultural crops with wide-gripping machines with water intake from open sprinklers. The purpose of the invention is to reduce unproductive water discharges and operating costs. The automated irrigation system includes a source of irrigation, a water distribution, sprinklers 4, on which baffles are installed in the form of water filling tanks 19 made of elastic material that are connected to the control pipe 18. The control pipeline 18 is equipped with pressure stabilizers 16 installed at the entrance water-filled tanks 19. The water supply stabilizer installed at the inlet to the irrigator is designed as a bottom-up level stabilizer with a flow limiter. When translating switch 17, the design element of the sprinkler when moving through the blocking structure, tank 19 is connected to the drain, water flows out, and the shutter is lowered to the bottom of the irrigator.

Description

The invention relates to agriculture and can be applied when irrigating agricultural crops with wide-gripping machines with water intake from open sprinklers.

The aim of the invention is to reduce unproductive water discharges and operating costs.

FIG. the general technological scheme of the automated irrigation system is shown; Fig. 2 shows a section of an Orozitel with blocking structures, re cut; in FIG. 3, a downstream leveling device with a discharge limiter.

The automated irrigation system contains 1 irrigation source | 1, a water distributor 2, a stabilized water supply system, an irrigator 14, a sprinkler machine 5, protective spillways 6 and blockade 7 with stabilizers 8 level differences.

The downstream 3-level stabilizer consists of a control device 9, a shut-off element 10, a level sensor 11 and a flow limiter in the form of a stop 12.

The level difference stabilizer 8 is implemented from the shutter 13, the control device 14 and the interaction mechanism 15 with the sprinkler. The control device 14 consists of a pressure stabilizer 16 and a water-filled tank of elastic material closed at the shutter 13, and water is supplied through the switch 17 of the control pipeline 8, the upper part of which is introduced into the water distributor 2 before the stabilizer level 3. An element 20 is introduced into the container 19, the volumetric weight of which is less than 1.0.

Automated irrigation system works as follows.

When the sprinkler works between the blocking structures, the switch 17 connects the output of the pressure regulator I6 with a capacity of 19, and maintaining a stable pressure in the latter ensures the operation of the shutter 13 in the mode of the level difference stabilizer. When switching the switch 17 to the design element of the sprinkler, the tank 19 is connected to the drain, the water flows out, to the shutter is lowered to the bottom of the irrigator.

After the passage of the machine, its design element ceases to interact with the switch 17 and it returns to its original position, the capacity of the word 19 is filled with water under the set pressure, and the shutter 13 is switched to the stabilization mode of the water level differential.

To ensure that the required amount of water is supplied, the downstream level 3 stabilizer opens the locking member 10 while the water level in the upper part of the sprinkler 4 decreases. The flow restriction is reached by a stopper in the form of a stop 12, which prevents opening of the locking member more than specified.

When a sprinkler is put into operation, the water level in this bay decreases, this leads to an increase in the differential on the gate that feeds this bay, and it almost immediately starts to bypass water from the diverted pool into the pool with the machine. The level in the previous pool decreases, so it begins to receive water from the previous pool and so on until the upper reach of the irrigator, lowering the water level in which leads to a gradual opening of the shutter of the stabilizer 3 until the irrigator becomes equal to the water intake by the sprinkler, which is observed at water levels in all irrigator pools, except for pools with a machine.
