(54) UNIT FOR COMBINED WATERING

1..2

This invention relates to agriculture, in particular to irrigation; "Ike," can be used in arperaVs for combined loliv.

A unit for combining irrigation is known, including a farm ic running along the pipelines, which are attached to a hose with a rotary valve and jets associated with the remote control mechanism jil.

The disadvantage of this unit is that its water outlets operate either in the sprinkling mode or in the (loliva mode without the possibility of completely shutting off all or a group of water outlets.

Another unit for combined loliv is also known, including water conducting along with irrigation and sprinkling springs, control devices and iHacoc 2.

However, regulating the flow of water from the working bodies by introducing a plug into the living section of the water outlet hole results in its fast clogging (at the point of constriction) by plant residues and suspended solids in the irrigation water, and a decrease in the reliability of the olic process.

The purpose of the invention is to increase the reliability of the unit.

The goal is achieved by the fact that

adjusting devices are made in

the form of crosses, lateral branches of which

equipped, diaphragm and connected to the pump and suction lines of the pump.

lia FIG. 1: a part of the water supplying system of the proposed unit is shown when sprinkling agricultural crops; in fig. 2 - the same, when irrigating agricultural crops in a superficial way from hose outlets; in fig. 3 - the same, when watering the combined | S1P | Special; in fig. 4 - the same, watering individual groups of working bodies.

15 The unit for a combined polpv consists of water-conducting sa / s polystyrene 2 and sprinkling 3 working bodies and regulating devices 4-5, made in the form of crosses with continuous holes 6 and 7 and lateral outlets 5 and 9. Water-conducting , 1 is made with holes 10 and .//, under each of which are installed adapters 12 and} 13.

25 Inside each outlet, in and 9, flexible membranes 14 and 16 are installed, connected by tubes 16 and tl7 to the pressure and suction lines of the pump.

The unit works for combined irrigation as follows.

When sprinkling agricultural crops (Fig. 1), each regulating device 5 of the sprinkling devices is connected to the suction line by a pipe, and regulating devices 4 to the pressure head. At the same time, in the recesses 9 of the regulating devices 5, a vacuum is created, by which "the membranes 15 are drawn in, fully opening the flow holes 7. In the control devices 4, the water supplied through the tubes M, the membrane M, is stretched, blocking the flow holes W, thereby disconnecting irrigation and working OraiHbi. In this way, the irrigation water from the water supply system along the river, / flows through the holes // and 7 to the sprinkling devices. The latter is divided into droplets and, in the form of rain, distributed over the irrigated area,

By adjusting the magnitude of the vacuum in the outlets 9 of the devices 5 by the membranes 16, they change the area of the living section of the flow holes 7, and thus the pressure in the whole water supply along the cross of the I unit. This makes it possible to create rain of the required intensity.

For the irrigation of agricultural crops by the surface method (Fn. 2), each regulating device 4 is connected to the suction line of the pump with 4 tubes M, and the device 5 is connected to the aporn. Then the membranes 14, retracted inside the taps 8, open up the living section of the openings 6, and the membranes 15 under the apor of water block access to the water B to the sprinkling devices. The irrigation water from the water supplying system is ca 1, the aperture opening of the LO and 6, enters the irrigated working bodies and is distributed in a concentrated flow into the field. . Changing the magnitude of the vacuum in the i5 taps with diaphragms, 14 devices 4, regulate the magnitude of the working flow rate of each water supply.

Connecting tubes 16 .and 17 regulating devices - and 5 with a pump's active line, they draw in membranes 4 and / 5 into outlets 8 to 9, thus opening the access of water to sprinkling and irrigation - working bodies and irrigating agricultural - cultures - in the combined way (fig. 3).

If it is necessary to irrigate a part of the area with a sprinkling or surface method, then the required group of regulating devices 4 n 5 sprinkler irrigation workers is connected with tubes 16 I./i7 to the suction line of the pump and opens, and the other part is closed by connecting to the pump pressure line of the pump. Fig. 4).

The use of the proposed sprinkler-field aggregate makes it possible to maintain high-quality “olive of agricultural crops with sprinkling, surface and combined methods with high reliability of regulating devices. ,

Claims (2)

Claim unit for combined irrigation, including WATER CONDUCTOR in terms of with FLUID and sprinkling sprays, and regulating devices and a pump, characterized in that, in order to increase its reliability in operation, the regulating devices are made in the form of crosses, with lateral taps which are fitted with membranes and connected to pump and suction line.
