Abstract

The invention relates to agriculture and can be used to automate the irrigation of agricultural crops. The aim of the invention is to improve the accuracy of irrigation control. The device for automated irrigation control includes an evaporometer G with a strain gauge 4 and a compensating device with a lever 7, a storage vessel 10 with a branch pipe 15 of its size and shut-off elements 26 of the irrigation network. The topping-up nozzle 15 is provided with an elastic insert 16. The storage vessel 10 is equipped with a set of drainage nozzles 14 and mounted on the lever 7 of the compensating device with the possibility of movement. Installing the storage vessel 10 with the ability to move on the lever 7 and supplying it with a set of spillway pipes 14 allows more precise control of the irrigation process. 1 il. 7J lO (L

The invention relates to agricultural farming and can be used to automate the irrigation of agricultural crops,

The aim of the invention is to improve the accuracy of irrigation control.

The drawing shows the core of the proposed device,

I The device consists of an evaporom g: pa 1, mounted on two passive 2 supports and one. active 3 containing a strain gauge 4, Evaporometer

has a drain hole

and needle sensor 6. The compensating device comprises a lever 7, a support 8: nezda 9 for fastening the storage vessel 10 and a compensator P. Co (; the bend storage drive 10 is attached to the lever with the support 12, it contains a rain funnel 13, a stop - 1s drainage pipes 4 with cranks and 1 pipes and topping-up pipe 15, connecting using flexible BCTaskH 6 and valve 17 with evaporometer i. Valve drive 17 is connected to level 6 sensor by means of control element 18 representing The 1st standard regulator of the level of discrete action. The branch pipe 19 of the vessel The JO jo is made calibrated and connected via an elastrin column to a pipeline 20 connected to a collector 21, I The strain gauge 4 is connected to block 2, which is also a dart element, containing 1–1 б b.yuk piHHHH, block excitation of the strain gauge And amplifier, Block 22 is connected with poro element 23j, the setpoint, il-o, is set by the operator, element code 23 is connected to pumping station 24. containing a timer (volume flow meter) 25. Water for irrigation pod 4ts pumping station 24 through the manifold 21 and the locking bodies 26.

The device works as follows. .

At the beginning of the season, the Evaporo Eter I is filled with water up to the level set by the Bottom Bore 5. The storage vessel 10 is installed in the nest 9 corresponding to the current value of the climate coefficient and is filled with water to the level by asking Mogo with the appropriate drain pipe 14 from which Lid Cap, What is more biocline gheskn th

The coefficient is the farther from the support 9 the storage vessel is fastened and the lower the water level is established in it, Dp facilities corresponding to each other sockets 9 and nozzles 14 have the same digital indexation. As the water evaporates in the evaporometer, the needle contact is broken. the sensor 6 with water and in the regulator 18 The command for opening the valve 17 is opened. The water from the storage vessel is poured out until the contact, the sensor 6 is restored again. At the same time, due to a decrease in the level of water in the storage vessel 10 at the output of the block 22, the signal is formed proportionally to the deficit of soil moisture reserves. If there is precipitation at the same time, they are collected in the lO vessel, getting there through a cavernous funnel 13 ,. At the same time, the water level Ei of the evaporometer does not change due to the drain hole 5. Sig-, feces proportional to the moisture reserve, decreases as the precipitation decreases, as it increases: the weight of the storage vessel iO decreases and, accordingly, the force on the sensor 4, drying the soil, as the signal at the output of the block 22 grows and it reaches the preset setpoint. signal, threshold element 23 is triggered and sends a command to turn on pumping station 24, water is supplied to coordinator 21 and irrigation network through shut-off members 26. The stop time 26 is determined by timer 25. When pressure is established in collector 21, water the pipeline 20 enters the capriched pipe 19 and then into the storage vessel 10. The flow area of the pipe 19 is calculated from the need to ensure that the storage vessel 10 is filled during the irrigation time. At the command of timer 23, watering is stopped and, at the same time, topping up storage vessel 10 is stopped. The device is ready for a new cycle of operation. If during the season it is necessary to change the bioclimatic coefficient, then the storage vessel 10 is moved to a new nest, the previous nipple 14 is closed with a key and another nipple 14 is opened, which corresponds to that slot 9. The water from the vessel 10 is drained (artificially opening the valve 17) or up to 31230674

flow through a funnel 13 or an evaporometer tube with a sensor and a compensated conductor 20. Elastic inserts 16 with a device with a lever, allow vessels to move the storage vessel with a branch pipe topping and the storage unit 10, retaining its well-hydrated porous irrigation network with the evaporometer 1 and the fact that, with
