the certain vehicle, in which, to improve performance and reduce the density of the metal of the unit, the upper belt farm made in the form of an inflatable sleeve, consisting of separate sections interconnected at the nodes of the farm through the separating diaphragms; the inner wall section of the inflatable sleeve reinforced with longitudinal bearing strands.

The disadvantages of the described construction are low technical and operational reliability, high consumption of materials and the cost of the upper inflatable sleeve.

Known irrigation machine [2], including hinged on the vehicle dual console farm water conveyance belt which is provided with the water outlet sleeve, in which, to simplify design, each console farm is equipped with a strained on its axis of symmetry by a rope, on which by means of a bent branch pipes fixed water outlet sleeve; elbows are pinned on the ropes and movably provided with retainers.

The main drawback of this design of irrigation machines - low operational reliability.

Known dual console sprinkling unit [3], including spatial suspension farm, consisting of three flexible belts, rigid triangle is astcote and reduce material consumption, a flexible belt connected to a pipeline stretching and pre-strained by the tension device, with two flexible belt forming the upper surface of the farm.

The disadvantages of the described construction are low technical reliability of the farm, complexity of design and low quality of rain.

A known machine for irrigation sprinkler and furrow [4], including mounted on a vehicle dual console farm water conveyance belt on which are sprinkler and irrigation nozzles, in which, to ensure the possibility of farm land and improve the quality of furrow irrigation, water conveyance belt is made in the form of three related section by section into a single rigid structure pipe, forming in cross section a triangle, with the top pipe installed sprinkler nozzle, which is connected via a slide switch having a diaphragm actuator, with one of the lower pipes, which are installed irrigation nozzle, and the third pipe is communicated with the upper pipe and associated capillary driven valve switch; upper tube sections water conveyance belt communicated among themselves, and pipe irrigation nozzles shall esto rain.

The closest technical solution is a farm irrigation unit cantilever type [5], including suspension with swivel-mounted on it two consoles, each of which is made in the form of mutually perpendicular vertical and horizontal trusses, flexible, belt, rack, struts, and sprinkler nozzles on the same hard water conveyance zone in which, to use the unit for both irrigation and furrow irrigation, and reducing the weight of the unit, each console is further provided with hard water conveyance belt on which you installed irrigation nozzles and ground support, as well as the horizontal elements of the farm. The unit is rigidly connected with the water conveyance belt vertical farm on the sprinkler nozzles at the ends of the racks horizontal and vertical farms in connection with flexible belts fastened by a stabilizing pendants, and racks vertical farm is equipped with articulated supports.

The disadvantages of this farm include high consumption, design complexity, low reliability and poor quality distribution of rain across the length of the consoles.

C is waiting on the length of the consoles, reduce material consumption, increase performance and technical reliability and increase performance.

This object is achieved in that the farm dual console sprinkler unit pipelines Central panel and water conveyance belt attached to the transverse vertical plane of the sprinkler Assembly form a catenary curve described by the equation:

y=(a/2)(ex/a+e-x/a)

where a is the distance from the surface irrigated field to the pipeline in the middle part of the Central panel;

e - the base of the natural logarithm (the number of NiPERA), e=2,71828;
