Wheeled sprinkler piping works as follows.

For sprinkler piping is mounted on the plot there is Granta 15, positioning the axis of the pressure power piping 2 perpendicular to the stationary pressure pipe 16. A flexible hose 14 is attached to the hydrant 15, and the opening of its valve wheel pipeline is put into operation. Water from the hydrant 15 through the sleeve 14 is fed into the cavity of power line 2. Of the different-sized by the diameter of the pipes 17 and 18 through the nipple 19 mechanisms of vertical self under the working pressure in the sprinkler nozzle 1. Sprinkler nozzles 1 of irrigation water in the form of drops of rain, evenly distributed over the irrigated area.

After making a given irrigation norms valve on the hydrant 15 block the supply of irrigation water. Operate the drain valve and the remainder of the water from the irrigation pipe is fused to the surface of irrigated land.

The operator of a wheeled sprinkler piping after closing the gate valve hydrant 15 detaches the flexible hose 14. Then start up the engine 5 combustion. By increasing the rotation frequency of the shaft is engaged in work gear and through chain transfer 6 receives the rotation of the bearing element 24 of the Central section 11.

Chain drives 7 and 8 from line 2 to receive the rotation of the pair of wheels 9 and 10. Torque on the bearing element 24 of the Central section 11 through the coupling 12 is transmitted to the and the flanges 22 and 23 adjacent the side sections 13. Torsion of bent profiles 25 causes rotation of the mounting ring 27 with the hub 27 of the wheel bearing 3. From the hub 27 of the supports 46 to force the roller is transmitted to the rim 45. Pokozachene 48 is progressively moving wheeled sprinkler from one hydrant 15 to another. When the vertical position of the nipple 19 on the pipes 17 and 18, the operator stops moving, turn off the engine 5. Then a flexible hose 14 connects to the next hydrant 15. When you open the valve the water from the hydrant 15 is supplied through a flexible hose into the cavity irrigation pipeline 2. As the movement of water in the cavity of the pipe 2 through the nipple 19 is a selection of water and the nozzle 1, it is distributed in a limited area.

Constant pressure along the length of the pipeline is provided by the reduced cross sections of joined pipes 17 and 18. This is achieved specified as the distribution of rainfall along the length of the wheeled sprinkler and width of irrigated land.

The implementation of irrigation pipe 2 made of polyethylene high-pressure pipes 17 and 18 prevents corrosion processes, ensuring that the specified period is a wide swath of the sprinkler. The separation of functions of the bearing member 24 and irrigation pipe 2 increases operational and technical reliability wheeled sprinkler piping. Clutch 12 ensure all work is completed as in amine pipes 17 and 18 of the cavity of the support member 24, and seal joints between different-sized pipes 17 and 18. The design of the drip line 2 in combination with the bearing element 24 in each section 13 (11) at the same applied to a wide pivot consumption there is the possibility of using more expendable sprinkler nozzles, providing a large radius of action. Due to this growing band of moisture on one position, reduces the number of idle travel, it saves one-time capital costs and reduced the number of hydrants.

Ends of tilted posts are relative mated from top and bottom by horizontally orientated brace. Mated ends of tilted posts are orientated downwards and arranged lower than brace. 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.
