The invention relates to agriculture and can be used in land reclamation drainage, watering systems, water activities, sewage and animal waste in the system sprinkling of distribution pipes.

Known irrigation system that includes a mobile collapsible irrigation pipelines, node distribution, in places where you installed the risers with sprinklers (nozzles) (G.M. Kulikov. Closed irrigation system. M., 1966, p.19-21, p.63).

The disadvantages of irrigation systems is the inability to locations of piping connections to make the management of irrigation package (s) irrigation pipes with different angles on parts of complex configuration, for example, a large circular fracture. Worse performance in the distribution of precise water and animal waste due to clogging of the nodes distribution in the fortified places of the riser. In this work irrigators heavy enough, directly on irrigation technologies in the field when the field is plowed, that is, the surface of the earth is not planned, creating a very complex topography, in addition, the area of irrigation depends on the slope.

Also known irrigation system including a water intake structure. the distribution pipeline, odor Opredelitel devices in places of diversion from the distribution pipeline, irrigation pipelines, consistently located along the length of distribution piping, and the difference between inlet and outlet parts of the pipeline (USSR Author's certificate No. 1727718, CL A01G 25/16, 25/00, E02B 13/00, 1992).

The disadvantages of irrigation system are: the complexity of the pipeline operation and the difficulty of applying the node distribution on the surface of the land with difficult terrain irrigated area (with its complex configuration), inaccessibility to its inspection and maintenance by irrigators, reduced operational capabilities for the use of wastewater and animal waste, saturated with various fibrous particles and silt. Maintenance of existing irrigation systems also identified two significant deficiencies in irrigation biologically treated effluent pigs. The first relates to intensive corrosion of aluminum pipes that come into disrepair after 4...5 years. Especially susceptible to corrosion degradation docking sites sites. Another negative phenomenon is manifested in the system - encrusting, that is, the formation of dense sludge inside regulating and shutoff valves. Complex and expensive valves reduces the operational reliability and reduces functionality, for example, when using irrigation during the plowing for Udo is satisfactory, irrigation, when the surface of the earth is not planned, the difficulty of the interchangeability of the nodes distribution, possible jamming of the float piston and the failure of the system as a whole; rinse such nodes is very difficult (impossible). Thus, the known device is not suitable for irrigation plots complex configuration, especially watering by plowing in agronomic timing preplant, autumn, steam and other plowing.

The purpose of the invention is to enhance reliability of the system operation and the use of drained lands through efficiency and quality control of liquid fertilizers in the current layer of moisture.

This goal is achieved by the fact that in the proposed regulation device for spreading liquid fertilizer in irrigation system including a water intake structure, distribution piping, water distribution devices in places of diversion from the distribution pipeline, irrigation pipelines sequentially spaced along the length of the distribution pipe, and the difference between outlet and inlet portions of the pipeline, characterized in that section of the distribution pipe provided with a corrector consumption of open type with input and output in the form of a fixed discharge elbow, which is mounted coaxially to the opening of the exhaust inlet is Alentova pipe with horizontal rotation and interact simultaneously with the discharge and irrigation pipelines, when the crank socket is configured to split the connection, and the body of the discharge pipe has an additional sprinkling apparatus, with the inlet of a bent pipe provided with bearings progress, with o-ring seal and the bottom of the inlet elbow is made to the water drain valve.

To eliminate the mentioned disadvantages of the prototype allows the regulation device for spreading liquid fertilizer in irrigation system with PTZ corrector open type with input and output in the form of a fixed discharge elbow. Using the PTZ corrector is provided by the rotation of the package (group) discharge of irrigation, transit pipelines at any given angle, describing the topography of the site and pronounced irregularities plowed fields with simultaneous supply of water or liquid fertilizer (sewage or animal waste), as all the pipelines and in a single pipeline. Possible scheme to transport water or liquid fertilizer pipeline and as a transport, with all the holes in the firmament of the discharge nozzle in this case, overlap, covers, and side holes, offset flow and sprinkler apparatus is stored. The turn angle of the pipeline has a fairly wide range is orota, more than 1°. With this device are used lightweight plastic irrigation piping with quick-connect connections on irrigation systems for manual control without much effort, and there are no obstacles for disassembly and Assembly, distribution and irrigation pipes. This increases the rate of introduction of irrigation system for irrigation of the field without special furrows and mechanisms of soil. Creates optimal conditions for accumulation of nutrients (fertilizers) evenly over the soil surface, the application mode of the sprinkler apparatus in the proof of the expenditure on irrigation system (as a way for irrigation and watering system). The proposed device provides means for regulating liquid fertilizers application in irrigation system when plowing in agricultural fields, irrigation, and can be attributed to reclamation systems, especially for disposal of treated animal waste and sewage.

The rate of absorption of water by the soil depends on the water resistance of soils, and irrigation technology. The resistance depends on the structure of the soils and underlying soil, the degree of processing, the initial moisture content and the dynamics of its change on the horizon. It is important to distinguish local resistance (surface basic sites or wetted perimeter is about furrows) and the resistance of the field. The latter is defined in the middle layer of irrigation water (liquid fertilizer), taking field per unit time.

The resistance of the field depends on the irrigation method, for example, when plowing across the entire field contours or along them, subject to appropriate processing technologies cultivated field mechanisms, which include disking, cultivation, which improves the water-air regime of soil and creates the most favorable and unique conditions for the development of culture around the field, which cannot be achieved with conventional irrigation sprinkler, as known irrigation potential discharges and pollution of drainage channels and extent of contamination to standards that do not allow the use of drainage water without additional purification for irrigation, recreation and other purposes that is in compliance with environmental requirements to agricultural fields, irrigation.

To obtain high yields it is important that all of the supplied liquid fertilizer remained in the topsoil evenly over the area calculated in the wetting layer. The techniques proposed irrigation modular systems allow watering without resetting. With all the mechanization of tillage and regulation of liquid fertilizer (water) across a plowed field, soil evenly (or hydrates) of the soil, and in this case, but the second proposed device provides the reliability of the system. A new idea to use concealer consumption of open type with input and output in the idea of a fixed discharge elbow on the sections of the portable distribution pipeline laid under a different corner of a ploughed field and in the direction of the angle is plowing to the main slope, allows to unify the design of the irrigation system by natural-climatic zones from the point of view of processing mechanisms in the form of disking and cultivation of the soil under agricultural crops in a short time, that is, from the point of view of soil in a short time under the crop. This method is progressive when watering in ploughing and can most efficiently use liquid fertilizer to the root zone soil layer at the stage of seed germination and thereby increase crop yields.

Additionally it should be noted that the adjustment method for making liquid fertilizers irrigation system and device for its implementation is such an important indicator as to increase the useful area of irrigation any complex configuration that depends on the proposed invention. To increase it, rather the increase in distribution pipes with offsets expenditure on schemes, for example, shown in the drawing.

Thus, the data system has significant advantages: on unit length of the pipelines have a large irrigated area (hydration). In addition, this unit can move through a plowed field to tillage and sowing seeds, i.e. more efficient use of agricultural machinery. For each field, you can set a specified number of distribution pipelines to offset consumption, as they are easily portable and detachable, and this, in turn, better performance not less than 2 times higher.

The distance between the irrigation pipelines are determined by the parameters of the sprinkler device. Machines can now be equipped with nozzles of different diameters.

By using the proposed invention at any stage effluent system allows glaze (hydration), as sewage and clean water. Removable concealer flow available for periodic inspection and flushing of the system does not break down the isolation and control valves, as well as the entire irrigation system.

New proposed device with this method of laying portable pipelines, provides the reliability and uniformity of the irrigation throughout the complex configuration of the plowed field. In addition, the direction of plowing is not playing the required irrigation technologies in the known devices of the field and in the direction of the angle is plowing to the main slope. All this paragraph is eduversum accidental discharges of the inclination of the plowed field. Watering of the field differs from conventional furrow irrigation.

Figure 1 is a flow diagram of a method for controlling liquid fertilizers application in irrigation system with options. Figure 2 - node system.

The system consists of: irrigation source 1 (for example, the drive for animal waste), avancuara 2, pump station 3, the discharge pipe 4 with an installed valve 5. The system includes a mixing chamber 6 (Staropramen) and a pumping station 7, providing a fence and is pumped into the pipe 8 with the valve 9 and hydrants 10 design flow of water or wastewater. The system also consists of the inlet pipeline 11, irrigation 12, 13 and outlet 14 piping, and installed between sections of pipe with offset consumption 15 with sprinkler devices 28.

The system may have a source of irrigation 16 clean water outlet pipe 17 and a valve 18 to supply water to the mixing chamber 6 (Staropramen). Possible scheme of irrigation systems, as the water recycling scheme, i.e., surface and drainage water reused for irrigation (hydration) by collecting water from open reservoirs 34 and the water supply from the drive 19, a pump station 20 directly into the irrigation system through line 21 or line 22 in the mixing chamber 6.

Concealer Rashad contains two elbow 23 and 24, one of them nozzle 23 is fixed to the output hole of the inlet of the duct 11, and the other branch pipe 24 is connected with the inlet opening 25, and a discharge pipe 14 and the holes 26, 27 irrigation pipes 12 and 13, placed at different elevations. This pipe 23 is installed coaxially to the opening of the discharge elbow 24 having a horizontal rotation and fixed to the chassis irrigation 12, 13 and outlet 14 pipelines. Elbows 23 and 24 are made detachable connection and connected between a special split clamp 33, and the arch (upper portion) of the nozzle 24 has a threaded hole where virtuves advanced sprinkler apparatus 28. In addition, the supply of a bent pipe 23 provided with bearings 29, with o-ring seal 30, in the bottom of the inlet tube is located drain hole 31 and a valve 32. While elbows 23 and 24 are connected with pipelines, special releasable clamps 34, 35, which enables rapid Assembly of a bent branch pipes 23, 24 and reliable operation of the PTZ corrector 15 a set (bag) pipes 11, 12, 13 and 14 in any position to operating mode. In General, the techniques proposed irrigation have a modular system that allows for watering without resetting. When designing a possible schema detach from the walls of the to body elbow 24 irrigation pipes 12 and 13, in addition to the outlet pipe 14, and the side holes on the wall of the elbow 24 are blocked by plugs (not shown) and collapsible tubing is used as transporting, and sprinkling apparatus 28 is stored (not installed). To collect runoff, such as water, has a closed open collector 36 with the drive 19.

To ensure ease of transfer and pickup pipe in hand on the field by irrigators, the pipe is additionally provided at the ends of the wire frame, the lower branches, which ring (capture) pipe. They can even be terminated under her pins (not shown to simplify the system, i.e. carry hooks with curved ends to hold the pipes on weight. Collapsible portable pipeline with the devices and with the spray sprinkler devices can be mounted on the uprights (legs), which serve as supports above ground height, providing a greater length of the circular spray, and after submitting the required layer of precipitation ease of disassembly and transfer to a new position.

The system works as follows. In the initial position of the inlet pipe 11 is disconnected from the underground hydrant 10, assemble collapsible pipes 11, 12, 13 and 14 plastic with mounting on the surface of the earth be the preliminary preparation, for example, when plowing, under the terms of the configuration and slope irrigated (irrigated) land. At the same time between the pipelines place and fix concealer consumption, and the pipes 12, 13 and 14 are placed at a given angle due to horizontal rotation of the elbow 24 around the elbow 23 with a given number of sections of piping in length, according to the specified schema. Thus, the layout of irrigation, transit pipelines and their combination are selected depending on the configuration irrigated (irrigated) area, the accepted method of supplying effluent (water) pipelines and accepted type of sprinklers 28, that is, the distance between the pipelines are determined by the parameters of the sprinkler devices and appliances watering.

The duration of irrigation or other land under irrigation pipes 12, 13 and 14 is determined by the work themselves sprinkler apparatus 28 that is connected to the arch of the elbow 24. Disabling all irrigation 12, 13 and outlet 14 pipelines, rotating and layout (transfer to manual) to a different angle relative to the elbow 23. and their subsequent inclusion through the corrector flow 15 in the work, provides the opening of the stationary hydrant 10 length closed distribution piping 8, the feed effluent (water) from a source'or the decision.

Carrying pipes 12, 13 and 14 (without water) can be performed in the field using a wire frame (not shown to simplify the system) or hooks with curved ends to hold the pipes on weight.

The number attached to the housing elbow 24 irrigation 12, 13 and outlet 14 of the pipelines, as well as combining them depends on specific local conditions. This allows you to maximize (simultaneously) area irrigated (irrigated) area and volume of application of effluent (water), and this leads to technological accepted scheme consistency of the pumping station and the activation sequence of the sprinkler apparatus 28, i.e. the time of their work.

Crankshaft socket 23 as the operating system is flushed with open valve 32 through the drain hole 31. In addition, the drain hole 31 is used for draining the water at the moment of disconnection of the system from watering and separation of the two crankshaft 23 and 24 nozzles. When complete removal of the effluent (water), sediment and debris from the elbow 23, the valve 32 returns to its original position to close.

It should be noted, to reduce runoff from irrigated fields in the collector - collector, irrigation devices can now be equipped with nozzles of different diameters, which will also retain the uniformity of the layer of rainfall runoff or water.

System alleycatallies, modular and simultaneously covers a large area irrigation (moisture), located in terrain conditions, especially irrigation of the field (this method of irrigation applied for the first time without cutting furrows).

A distinctive feature of the double-acting systems is that drained the area heavily used when the soil is still at the stage of the arable layer hydrate livestock wastewater or clean water sprinkler, depending on terrain, techniques of water management, network diagram, conditions of water intake and types of distribution devices.

The proposed system represents a single reclamation system consisting of independent irrigation parts and elements, for example, in the mode of irrigation and soil moisture.

The system of collapsible lightweight piping with gasketed offsets the consumption of open type is mounted on the surface of the earth without its preliminary training after plowing for transporting sewage, animal waste or clean water from the sprinkler nozzles. The design of the connection of the pipe sections with offset consumption of open type provides quick Assembly and disassembly, and reliable operation of the irrigation system. Removable concealer flow available for periodic inspection and possible washing and network will not interfere with the operation of control valves and irrigation system.

The effectiveness of the invention is that it allows the module to fit into the configuration plowed any of irrigated land increases the reliability and speed (quick transport network) change irrigation plot in any direction and facilitates the work of the irrigators, especially when moving drains or water on the soil surface and thereby the seed and the harvest will be reliable (guaranteed).

High efficiency is also achieved from the use of the proposed irrigation, discharge piping and sprinkler devices, i.e. package interchangeable devices (elements in irrigation technique). Seasonal load on the operator can make up to 500 hectares efficiency irrigation techniques to 0.98. The elements of the system are easily unification and workmanship for outdoor irrigation systems by assembling from parts made on the relevant industrial plants, workshops.

SUBSTANCE: apparatus has accumulation reservoir with bottom opening closed with valve, auxiliary reservoir, two float valves, one of said valves being designed for feeding water to accumulation reservoir and other valve serving for cutting-off said feeding process. Valve floats are positioned within auxiliary reservoir positioned lower than bottom of accumulating reservoir and connected through flexible pipelines to hermetically sealed reservoirs having porous bottoms and embedded in soil. Drawing of water by soil through said bottoms results in reduction of water level within auxiliary reservoir. Float valves are opened and water is delivered through one of said valves into accumulating reservoir. On reaching of predetermined water filling level, discharge opening valve is opened and water is delivered into low-pressure irrigation system and through other float valve into auxiliary reservoir. Increase in water level within accumulation reservoir cuts-off feeding of water into this reservoir. During operation of high-pressure irrigation system, functioning of apparatus is regulated by filling of accumulation reservoir to certain small volume and stabilized by means of detachable reservoir adapted to be mounted on accumulation reservoir and having horizontal partition walls.

EFFECT: increased efficiency and enhanced reliability in operation of apparatus.
