The set of locally-pulse irrigation relates to agriculture, in particular to the mechanization of irrigation, and can be used for irrigation of agricultural crops by discrete (pulse) supply of water in the pockets of moisture.
A device for watering (set), containing an accumulation tank with a siphon, reported the drain part with irrigation pipelines, the charging mechanism of the siphon and the supply tube to the faucet, with drain part of the siphon is in communication with the irrigation pipelines through manifold contains tubes with holes in the walls, placed in its cavity, while the siphon is made in the form of a bundle of tubes, the drain of each of which is communicated with a corresponding tube collector .
A disadvantage of this device for watering is the lack of uniformity of distribution of irrigation water through the culverts due to the influence on the start of the siphon state irrigation pipes and due to the different duration of the run irrigation pipes.
A device for watering (set), including the accumulation tank with a siphon, reported the drain part through a manifold with irrigation piping, feed tube with stopcock and the charging mechanism of the siphon, and the ejector mechanism of charging the siphon is made in the form of a tube with holes in its wall, and the bottom is the end of this tube is articulated through the through slot in the housing of the collector with one of the irrigation pipes, and its upper end positioned in the cavity of the drain side of the siphon, these hole in the wall of the tube is located in the cavity of the manifold below the end of the drain side of the trap .
A disadvantage of this device for irrigation is a low reliability due to the influence of the condition of the irrigation tube to start the siphon, the lack of uniform distribution of irrigation water through the culverts because of the dependence of the duration of the start of the siphon from the hydraulic conditions of the irrigation tube connected with the ejector. Install the reservoir above the level of the irrigated area and the connection of the input ends of the irrigation pipes to it leads to a deterioration in the distribution of the discharge flow rate of the siphon between the irrigation pipelines in the final phase of its work. Install culverts at the level of irrigation pipes leads to unwanted emptying irrigation pipes after each irrigation, which degrades the uniformity of the distribution of irrigation water on area and increases the length of the next run of the kit. This embodiment culverts makes growing plants in small containers and to apply irrigation water directly to the root system of the plants, which generally reduces the efficiency of the set.
The aim of the invention is to improve the reliability and efficiency and set work and improving the distribution uniformity of irrigation water through the culverts.
This goal is achieved by the fact that the set of locally-pulse irrigation, including cumulative capacity, the supply tube with a valve, a siphon with a drain outlet, the receiver-reservoir and irrigation piping with outlets, the outlets are made in the form of microrobot connected to the input ends with irrigation pipelines, and the output is with the atmosphere, while irrigation pipelines are located below the output ends of microrobot, and the cavity of the receiver-reservoir is hermetically connected with the drain outlet of the siphon, and the upper and lower ends communicated with the atmosphere above the level of the drain outlet of the siphon and with irrigation tubes at the level of irrigated land.
The invention is illustrated by drawings, in which Figure 1 is a wiring diagram of the set of locally-pulse irrigation; Figure 2 - view of the complete set on the receiver side of the manifold; 3 - storage tank with siphon feeding tube and receiver-header.

The output end of microtubules 16 is connected to the top h is STU small container 17. Tee 12 (3) horizontal end hermetically connected with the drain outlet 7, and the upper and lower ends, respectively, with the atmosphere through pipe 10 and the tee 13 through pipe 11. Tee 13 and irrigation piping 14 is installed on irrigated land, below the level of the output ends of microrobot 16 and interconnected.
The set of locally-pulse irrigation on irrigated area is mounted as follows. Accumulation tank 1 with the siphon 6 is mounted above the level of the irrigated area at a height determined by the height of the receiver-reservoir 9. Collect the receiver-reservoir 9 by means of branch pipes 10, 11 and 12 tees, 13 and hermetically connected with the drain outlet 7 using the horizontal end of the tee 12. Irrigation pipelines are alternately stacked on the surface of the irrigated area so that their free ends have been directed towards the accumulation tank 1 and connected to the outlets of the tee 13 receiver collector 9 (Figure 1). The input ends of microrobot 16 connect with irrigation piping 14, and the output ends are installed on the upper level low-volume containers 17. One end of the supply tube 3 is connected with a source of water and the other with the valve 4 and then through the knee 5 - with the cavity of the storage tank 1. Close accumulation tank 1 cap 2. The kit is ready for operation.
Has a set of locally-pulse irrigation in the following way. Water from the source through the supply tube 3, the knee 5, with a certain flow rate, set by the valve 4, is fed into the accumulation tank 1 (Fig 3). The water level in the tank 1 will begin to slowly rise from the lower level (WELL). When the siphon 6 eliminates the possibility of water leakage from the tank 1 through the discharge outlet 7 into the cavity of the receiver-reservoir 9. When the level of water in the tank 1 top level (WU) siphon 6 abruptly started and the accumulated water from the tank 1 with a large flow through the drain outlet 7 is supplied into the cavity of the receiver-reservoir 9, then through irrigation pipes 14 with plugs 15 are evenly distributed over the irrigated area through microtubules 16 in the form of streams, through locally-pulse low-volume watering containers 17. By reducing the water level in the storage tank 1 to the siphon 6 razreshaetsja and watering stops. Further, while water flows into the accumulation tank 1, the loops are relatively slow filling of the tank 1 and its rapid emptying repeated automatically and do locally pulse-watering containers.
Improving the reliability of the package is achieved by eliminating the influence of the state irrigation pipes at the start of the siphon 6, by means of a sealed message cavity p is jennica collector 9 with a drain outlet 7 and with the atmosphere above the level of the discharge outlet 7.
Improving the efficiency of the kit and the improved uniformity of distribution of irrigation water between containers 17 is achieved by performing the culverts in the form of microrobot 16 located output ends above the level of irrigation pipes 14, so after irrigation irrigation pipelines remain filled with water, which contributes to fast the next run of the siphon 6 and the rapid establishment of watering, which ultimately lead to increased uniformity of watering containers 17.
Thus, the implementation of water discharged in the form of microrobot located output ends above the level of irrigation pipes, and message of the discharge outlet 7 is sealed with the cavity of the receiver of the collector 9 and the cavity of the receiver-reservoir with the atmosphere above the level of the discharge outlet 7 has improved the reliability and efficiency of the kit and to improve the uniformity of distribution of irrigation water between the containers 17.
