Known wide-wheeled sprinkler, produced by domestic machinery under the brand name BARN-64 “Volzhanka” and consisting of the power of the pipeline in the form of two wings on wheels. Power piping serves as the axis of rotation of the support wheels. In the centre of the wing is driving the truck with an internal combustion engine. Wing power piping attached to the hydrant by means of flexible hose. On the pipeline by mechanism of self fixed sprinkler apparatus. Under each device there is an automatic drain valve (see Agriculture and melioration machines” Hesistated, Gccepib, Budzanow, etc. Under the General Ed. Hesistated. - M.: Agropromizdat, 1986, - 688 C., Il. (Textbooks and textbook. benefits for the high. educational institutions). - S, RES 243, b).

Power piping 7 in the side sections 5 and mutually in the Central section 4 are connected by couplings 8 (see figure 2). In each section 4 (5) water conveyance pipe 7 is made of polyethylene pipes length of low-pressure or 4, or 6, or 12 feet of Polyethylene pipe are interconnected by couplings 8. Water conveyance pipeline 7 is placed in the cavity of the bearing member 9. Supporting member 9 is formed of C-shaped soil profiles. The ends of the bearing members 9 provided with flanges 10. Flange 10 adjacent bearing elements 9 are mutually connected by means of the fastening means placed in the holes 11. The hub 12 of each wheel Assembly 2 having a rim 13 with pokozachene 14 and spokes 15, covers the supporting member 9. Sprinkler nozzle 6 is connected with a water conducting pipe 7 through the nipple 16. The nipple 16 on the surface of polyethylene pipes placed between the shelves adjacent the C-shaped bent shape of the bearing member 9. Sprinkler nozzle 6 with the nipple 16 is connected through mechanisms of self because of the popularity of mass-produced unit (not shown).

Wide wheel sprinkler operates as follows.

Installed at positions aligned wide-wheeled sprinkler with node 1 connected to a hydrant connected to a closed irrigation network and open the hydrant,allowed the water. Water plastic pipe low pressure from the extreme right side of the section 5 is supplied to the Central section 4 and further to the far left side section 5. Water under pressure from the cavity water conveyance pipeline 7 comes first in the nipple 16, and then through mechanisms of self-directed in sprinkler nozzles 6. Sprinkler nozzles 6 are issued in the form of rain irrigation norm. At closing of the hydrant is closed irrigation network triggered drain valves. Unused water from the water supply pipe is fused to the surface of irrigated land. The operator wheeled sprinkler includes an actuator 3. When the engine is running through the system chain gear drive 3 bearing element 9 receives the rotation. Bent C-shaped profiles connected by flanges 10, work well as torsion and bending. Due to the torque bearing element 9 through the hub 12 and the spokes 15 transmits the force on the rolling carts 13. Povazay 14 prevent slippage on wet ground wheel supports 2. Wheel bearings 2 bearing elements 9 of the Central section 4 is moved to the new position of the side sections 5. After stopping the wheel of the sprinkler to a new position to achieve the vertical position of the nipple 16 of the sprinkler nozzles 6. Water conveyance pipeline 7 did not participate in the work of transport Perea is de wheeled sprinkler. After alignment of the bearing member 9 on the new position of the node 1 is connected to the hydrant irrigation, and the irrigation process is repeated.

Due to the fact that water conveyance pipeline 7 is solely a function of water distribution along the length of the wide-wheeled sprinkler and it's made of cheap anti-corrosion material, is achieved by simplifying the design, reducing material consumption and prices, as well as increases the service life of the sprinkler.
