(57) Abstract:

Usage: devices for irrigation of agricultural crops by discrete supply of water in the pockets of moisture. The invention consists in that the device for irrigation, containing the distribution and irrigation piping with outlets, storage capacity 6, the supply pipe 7 with the crane and work siphon 8 tube sensor 13 liquid level reported by the suction part 10 with a storage capacity of 6, and the drain 12 - distribution pipeline, pipeline network is made in separate sections, the drain part of the working siphon 8 is equipped with an automatic flow switch 9 irrigation water, consisting of siphons 17 air / water valves, recessed ends of the drain portions 18 in the cups 19 with the output pipe 20 and the joint between the suction parts 21 through manifold 22, the control chambers 23, hydraulically connected to each other, the dispenser automatic water supply 24 in the control chamber 23 and the hydraulic system of the communication channels 25. After irrigation, the water pressure in the working section of the falls, the water from the communication channel 26 begins to leak, posing as a siphon and emptying the control chamber 23, the Yelsk agriculture, in particular mechanization of irrigation, and can be used for irrigation of agricultural crops by discrete supply of water in the pockets of moisture.

A device for discrete irrigation, including water-lifting mechanism, a pipe network with outlets, accumulation tank, the siphon with the mechanism of activation [1].

A disadvantage of this device for discrete irrigation design is the complexity and lack of reliability.

The closest in technical essence to the present invention is a device for watering, including distribution and irrigation piping with outlets, storage capacity and siphon mechanism run [2].

A disadvantage of this device for watering is the fact that with the increase in irrigated area dramatically increases its specific consumption due to increase storage capacity and diameter of the pipeline network, which also leads to the decrease of uniformity of distribution of irrigation flow between outlets.

The problem to which the invention is directed, is a reduction in specific energy consumption of devices for irrigation and improving the distribution uniformity of the device on irrigated land; in Fig. 2 is a schematic structural diagram of a head node of the device (section a-a) of Fig. 3 - section b-B in Fig.2; Fig. 4 - section b-b of Fig.2; Fig.5 - node I in Fig.3. in Fig.6 - schematic hydraulic diagram of the head unit.

Device for irrigation consists of a head node 1 and a network of pipelines 2. The network of pipelines 2 made in the form of separate sections with junction 3 and irrigation 4 pipelines with outlets 5. The head node 1 contains a cumulative capacity of 6, the supply pipe 7 with the crane, work siphon 8 and automatic flow switch 9 irrigation water. Work siphon 8 consists of 10 with the suction pipe 11 and the drain 12 parts, the tube, the liquid level sensor 13, the de-aeration tube 14 and the glass 15 and a pipe 16 to disrupt the vacuum siphon.

Automatic flow switch 9 irrigation water contains: section 17 (I, II, III, IV), recessed ends of the drain portions 18 (I, II, III, IV) in glasses 19 (I, II, III, IV) of the output nozzles 20 (I, II, III, IV) and the joint between the suction 21 (I, II, III, IV) parts by collector 22, the control chamber 23 (I, II, III, IV), hydraulically connected, dispenser automatic water supply 24 V control camera and gachi water 24 (see Fig. 4) in the control chamber 23 is made in the form of a siphon 31, the drain portion 32 which is omitted in the supply chamber 33, and the suction portion 34 fitted with a metering Cup 35, the cavity of which mikrofonom 36 communicated with the cavity plum part 32.

The control chamber 23 (I, II, III, IV) communicated by the communication channel 30 with the supply chamber 33, the communication channel 25 (I, II, III, IV) with the corresponding drain portions 18 (I, II, III, IV) siphons 17 (I, II, III, IV) and the communication channels 26 (I, II, III, IV) with the output connections of suction parts 21 (I, II, III, IV) glasses of 19 (I, II, III, IV), and the collector 22 is communicated with the discharge part 12 working siphon 8, with the atmosphere - communication channel 29 and outlet pipe 20 through the communication channel 27 with a choke 37.

The communication channels 26 (I, II, III, IV) is made in the form siphons, intake ends of which are located in the control chambers 23, and the drain side is connected to the output nozzles 20 (I, II, III, IV). The control chamber is in communication with the outlet nozzles through the communication channels as follows: 23II20Ithrough the 26IIthe 23III20IIthrough the 26IIthe 23IV20IIIand the 23I20IVthrough the 26IVi.e. each control chamber communicated with the previous outlet pipe, and 1-I control the camera from the last weekend of patrol is part of the overall glass 38, in which you installed the end of the sensor tube 13.

To prepare the device for operation it is necessary to pre-fill water reservoir 22, glasses 19 (I, II, III, IV) to the level of output nozzles 20 (I, II, III, IV), the supply chamber 33 and the control chamber 23 (I, II, IV) except for the camera 23III(see Fig. 1, 6). All cameras except the 23IIIset the water level to a communication channel 20, so that the siphons 17 (I, II, IV) change their properties and turn into water-gates, as their discharge ends of flooded water in the cups 19 (I, II, IV), and the cavity is cut off from atmosphere by flooding ends of the communication channels 25 (I, II, IV) in the control chambers 23 (I, II, IV). Siphon 17 (III) remains the property (as siphon), as its internal cavity remains communicated with the atmosphere through the communication channel 25IIIempty control chamber 23III.

Device for irrigation works in the following way. Water supply tube 7 flow specified by the crane enters the holding tank 6. The water level in the tank 6 increases slowly, displacing the air from the suction portion 34 siphon 31 through microsite 36, and after filling of the metering Cup 35 is reached the junction of the sensor tube 13 to vsasyvauschie the second tube 14 removes the air from the suction part 10. Thus started work siphon 8 and the tube 16. Water high consumption enters the collector 22, the water level is rising sharply above the upper levels of suction parts 21IIIIIIIVsiphons 17IIIIIIIV. When the water level rises sharply only in the suction part of the 21IIIsiphon 17IIIbecause of both its internal cavity of the air may be freely disposed of to the atmosphere through the communication channel 25IIIand blank control chamber 23III. In the rest of suction parts of the 21IIIIVthe water level does not rise to the upper levels, as the internal cavity of these siphons cut off from the atmosphere and increasing the level leads to the compression of air in them, i.e. siphon 17IIIIVturn into water-air shutters. Because of this and the de-aeration channel 28IIIsiphon 17IIIabruptly started, feeding water through the outlet 20IIIdistribution and irrigation pipeline 3 pipeline 4 with outlets 5 on irrigated area, serviced by a single section of the irrigation device. When the water pressure operating section rises in the communication channel 26IIIand displaces who is

During periods of low water level in the tank 6 dosing Cup 35 remains full, and in the oral siphon 31 is a vacuum created due to the fall in water level at its suction side 34, as the discharge end 32 and the suction part of mikrofona 36 inundated. By reducing the water level in the tank 6 to a certain point microsite 36 is started and the water from the Cup 35 is poured into the supply chamber 33 and forth, filling the empty control chamber 23IIIuniformly distributed in all cells of the control.

Further lowering of the water level in the tank 6 to the level of the upper edge of the Cup 15 after the liberation of the end of the suction portion 34 siphon 31 leads to slow suction of the water through the tube 16, which, upon completion of suction of water connects the suction side 10 of the working siphon 8 with the atmosphere, resulting in disruption of the vacuum and siphon 8 abruptly stops.

Stop watering section of the siphon 17IIIthe water pressure in the working section of the falls, the water from the communication channel 26IIIbegins to flow, creating a negative pressure in the channel, causing the channel 26IIIworks as a siphon and empty control chamber 23IVthus podgotovlennye section of the pipeline network will be repeated automatically. To switch the device off from work it is necessary to close the valve on the supply pipe 7.
