The invention relates to agriculture, namely, to sprinkler installations.Known sprinkler in which to regulate the amount of irrigation water used pressure the water pressure in the network (USSR Author's certificate N 85150).However, this known sprinkler does not change the position of the nozzles relative to the earth, which leads to the ingress of water at the same place, and hence the erosion of soil and its local waterlogging.Known sprinkler in which the spray liquid is changed under the action of pressure of pressure of the feedwater. For adjusting the position of the watering pipe with nozzles above the earth's surface provides a mechanism in the form of trossoblochnoy system. However, the regulation is carried out discretely, only to supply water to the system, i.e. when the system is turned off irrigation (USSR Author's certificate N 1029913, class A 01 G 25/02, 1981).The disadvantage of this device is cicenia irrigation area by changing the position of the spray nozzles relative to the earth, you must stop watering, change with trossoblochnoy system the position of the nozzles, and then again to start the installation.The technical result achieved by the invention is to improve the efficiency of irrigation by automatically changing the position of the nozzle relative to the surface of the earth, and thus change the angle of the spray of water, as well as providing easy operation of the device by eliminating the need for its off in the process.This is achieved by the fact that in sprinkler installation, comprising a movable irrigation line with the nozzles, the mechanism changes its position relative to the earth's surface, the means for connection of power systems and supports the distinctive feature is that the mechanism includes a housing, inside which is placed the impeller gear with blades, gearbox and multi-directional flow of water, irrigation pipe is hollow and open ends, and a hollow end placed in one of the supports for rotation therein, and an outdoor rigidly connected to the hull, which, in turn, is rigidly connected to the block allocator, made in the form of clips, a closed disk with two to the existing swivel rocker and installed with the possibility of alternating overlapping nozzles, in this clip from the disk mounted on the shaft-gear, which made a blind hole, ending with a radial through groove and the console pipe form a common gap in the area where the blades of the impeller-gear interacting through a reduction gear c shaft-gear, the free end of which is rigidly connected to the axial inlet of the drum, which serves as the second pillar and provided with two disks-regulators, is also fixed on the axial pipe that connects to the power system.Disks regulators it is reasonable to provide an annular groove, the annular protrusion and a peripheral annular groove, and the rocker arm to provide a shank extending from the casing and communicating with the annular grooves of the disk controllers. The clip is recommended to provide a finger located diametrically opposite from the output shaft-rocker and interacting with peripheral annular grooves disk controllers. The nozzle is recommended to have in the middle part of the pipeline is made arcuate. It is advisable slit to divide the dihedral angle, the edge of which is directed towards the impeller-gear and parallel to its plane, and positioning the slit-asymmet the social setting, General view of Fig. 2 mutual arrangement of the blades of the impeller-gear and cracks.Sprinkler consists of a curved watering pipe 1 with straight ends and outlet openings of the nozzles mounted on the curved part of the pipe. One free end of the pipeline deaf (closed off by a plug 2) and is mounted for rotation in the support 3, and the other (open) end fixed in the housing 4 of the mechanism of rotation of the pipeline mechanism changes the position of the pipeline relative to the surface of the earth). The mechanism interacts with a support 5, which is made in the form of a drum provided with internal axial nozzle. In the end supports attached nipple 6 with filter grid connected power system. In the open end of the drum bearing on the inner axial inlet planted two disk controller 7, each of which is provided with an annular groove, the annular protrusion that restricts the rotation of the disk controllers to one another, as well as peripheral annular groove. The body 4 of the mechanism of rotation of the pipeline is executed in the form of glass, within which is placed the impeller-gear 8, the block valve 9 water flow and the gearbox 10. The block p is valid with peripheral annular grooves disk controllers 7. The end of the casing is closed by a disk 13, which is equipped with two cantilever spaced axes 14 to the gear 10 and the two cantilever pipe 15. The disk 13 inside the casing 11 in the area of the openings of the nozzles 15 is installed saddle 16, a spring-tensioned arm 17 with the shank 18 that extends beyond the holder and communicates with the annular grooves of the disk controllers 7. The yoke 11 and the disk 13 mounted on the pinion shaft 19. Pinion shaft is made with a blind hole, passing through the radial grooves, which are located in the area of installation of the saddle with a yoke, and an end face of the shaft-gear side gear provided with a shank 20. The free end of the pinion shaft with an open axial bore includes internal axial pipe drum bearings 5 and communicates with the hole of the nipple 6. The ends of the pipes 15 into the hole of the disk support 21, which also made blind holes for axles 14 and the shank 20 of the pinion shaft 19. On the axes 14 mounted gear reducer 10, transmitting rotation from the impeller-gear 8 to the shaft-gear 19.The nozzles 15 form a common water outlet slot 22, in the area where the blades of the impeller-gear 8, which is freely mounted on the axis of the disk support 21. The slit 22 raspolozheno parallel to the blade and is directed toward the blades of the impeller-gear.Sprinkler operates as follows.Water from the power system through the nipple 6 with filter mesh comes in a blind axial hole of the pinion shaft 19 and out through the radial groove, fills the inside of the cage 9. In a further admission of water its jet will affect the saddle, which opens one of the nozzles 15, and the water seeks it. After the pipe 15, the water will come out of him, and through the slot 22 of its jet will affect the blades of the impeller, causing it to rotate. As water flows without interruption, it fills the body of the mechanism and then goes to the watering pipe with nozzles. At the same time, the rotation of the impeller-gear 8 is transmitted to the gearbox, which communicates with the shaft-gear 19. But as the holder of the block valve is rigidly connected to the housing of the mechanism, then turn and he, consequently, irrigation line, which is also associated with the case. But the rotation of the housing with the holder 11 is limited by the angle of the peripheral groove sector regulator 7, which includes the finger 12 of the bracket. Moreover, this angle is consistent with the angle annular groove sector regulators, which includes the shank 18 of the rocker arm 17. The shank 18, dogac 15. Water will flow in the other nozzle and the jet will exit slit 22 and act on the blades causing them to rotate in the other direction as long as the finger 11 will not reach the other peripheral groove of the disk controller.Thus, irrigation line, turning in one direction and then in another direction, and provides even watering throughout the captured area. 1.
