Sprinkling machine is mounted on the tractor frame 1. The tractor 1 is preferable to use class thrust 3 caterpillar modifications. Sprinkling machine is equipped with a pumping unit 2 with floating intake valve 3. The intake valve 3 allows the movement of the tractor 1 to suck the water out of the open sprinkler. On the tractor frame 1 is mounted pillar 5. On the center pillar 5 via the cable stretch marks 6 is suspended from the left pipe 7 and the right pipeline 8. The pipes 7 and 8 are connected pivotally with the Central nervous system, the second counter 5 and hydraulically connected by means of a sleeve 9 with the pressure cavity pump unit 2. Central hour 5 cable stretch marks 6 and the pipes 7 and 8 have the ability to rotate 90° around the vertical axis. The left pipe 7 and the right pipe 8 are at the free ends delestraint apparatus 10 (figure 3), and along the pipes evenly placed korotkometrajnye nozzles 11 (figure 5). The pipes 7 and 8 with the Central stand 5 optional connected mechanisms 12 changes the angles of the pipes 7 and 8 to the horizon. Mechanisms 12 made in the form of hydraulic power cylinders mounted bases on the center pillar 5, and the rods kinematically connected with the ends of the rope marks 6.

Delestraint apparatus 10 and korotkometrajnye nozzles 11 on the pipes 7 and 8 are mounted with the possibility to save the vertical position of the housings 13 and 14 by means of counterweights 15 when changing the inclination of the pipes 7 and 8 to the horizon. Each of the counterweights 15 has a body. The body of the counterweight 15 is placed can be rotated around a horizontal axis on the threaded sleeves 16. The sleeves 16 have threaded sections at their ends, both external and internal surfaces. The sleeves 16 has a group of radial holes 17. One end of the sleeves 16 is fixed by a nut 18 threaded portion horizontally-oriented pipe 7(8) of the nipple 19. With another cone (cavity with whom she's 16) is closed by a threaded plug 20. The body of the counterweight 15 is placed on the outer surface of the sleeves 16 between the washers 21 and 22 made of antifriction material. The sleeves 16 are made of stainless steel. The outer cylindrical surface of the sleeves 16 are subjected to grinding. Washers 21, 22 and the body of the counterweight 15 mutually preloaded elastic elements in the form of a compression spring 23. The compression spring 23 disposed between the shaped washer 24 and the disk 25. The disk 25 with a lock nut 26 is mounted on the free threaded end of the sleeves 16. The body of the counterweight 15 has a cavity for filling with liquid ballast. The bottom part of the housing 15 is closed by a plug 27. In the cavity of the housing 15 liquid ballast (water) flows through the radial holes 17 of the sleeves 16 of the nipple 19. Referred to the body cavity of the counterweight 15 is hydraulically connected with a threaded socket 28 for mounting of the housings 13 and 14 or delestrange sprinkler apparatus 10 or kratkotrajni nozzle 11.

Sprinkling machine operates as follows.

When driving the tractor 1 open along the nozzle 4 and operating the pump unit 2 water intake valve 3 is directed into the cavity of the pump unit 2 and under pressure enters the sleeve 9, and from them into the left and right pipes 7 and 8. When the admission of water under the working pressure in the cavity of the piping 7 and 8 through the nipple 19, it is sent to the sleeves 16. From the sleeves 16 through radial holes 7 water is directed into the cavity of the buildings of the counterweight 15. The water fills the cavity of the sleeves 16 and buildings balances 15. Due to the mass of liquid ballast in each block of the counterweight 15 is in the vertical position, rotate around the horizontal axis of the nipple 19 and the sleeves 16. The compression spring 23 through the shaped washer 24 and washers 21 and 22 presses the body of the counterweight 15 to the nut 18, except that the leakage of water between the surfaces of the nipple 16 and the body of the counterweight 15. The threaded socket 28 together with the housing 13 (figure 4) or with the housing 14 (figure 5) occupy a vertical position. Water under pressure is supplied to the deflector portion kratkotrajni nozzle 11 and is broken into small streams, and then drops of rain acts on the surface of irrigated land.

When watering crops in calm weather (wind speed less than 3 m/s) mechanisms 12 pipes 7 and 8 together with delestraint apparatus 10 and korotkometrajnye nozzles 11 raise above the surface of the irrigated area. Due to the high altitude installation delestrogen apparatus 10 at the ends of the pipeline sections 7 and 8 increases the range jets of water that collide at a meeting with the air flow, in the form of small droplets washed leafy mass of agricultural crops and irrigate the root layer of soil, increasing the lower threshold of moisture content to the optimum values.

When the work is in a period of drought (when the wind speed exceeds 5 m/s and ambient temperature of more than +25...+28° (C) the operator of the pivot mechanisms 12 pipes 7 and 8 results in a horizontal position (see figure 1). For account balances 15 each kratkotrajna nozzle 11 and each delestraint device 10 occupies its working position, providing a specified quality of rain and excluding demolition wind rain clouds.

After watering at the site of the pipes 7 and 8 mechanisms 12 on the center pillar 5 lead in transport position (see figure 2 and 3) to move the pivot technological road along the nozzle 4.

Ends of front and rear water tubes in guy-rope part are relative mated by V-shaped water supply member with tube of truss guy-rope part. Panels of guy-rope part of truss are formed by posts and braces, tilted struts and tension members orientated in longitudinally vertical plane. water supply pipeline of guy0rope part is furnished with drain valve. Proposed truss provides 15-20% reduction of materials usage.

EFFECT: improved quality of sprinkling, facilitated servicing.

FIELD: agricultural engineering, in particular, irrigation equipment, more particular, continuous motion sprinkler machines for farms.

SUBSTANCE: girder has central panel with two cantilevers pivotally fixed thereon. Each of two cantilevers is made in the form of mutually perpendicular vertical and horizontal girders having belts, columns, angle braces and sprinkler heads on water supply girder. Pipelines on central panel and water supply girder are made in the form of curved circuit line in transverse-vertical plane of sprinkler unit. Circuit line equation is y=a/2(ex/a+e-x/a), where a is distance from surface of field to be irrigated to pipeline arranged in mid portion of central panel; e is Napierian base (Napierian number); x and y are abscissae and ordinates of unknown points of pipeline in Cartesian coordinates XOY, the beginning part of which is aligned with field surface and with vertical axis of symmetry of girdle.

EFFECT: enhanced reliability in operation and increased efficiency.
