The invention relates to agricultural machinery, namely, irrigation technology, and can be used in machines farming type for sprinkling in continuous motion.

Known sprinkling unit, including dual console farm with lower water conveyance belt installed on the 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 (SU inventor's certificate No. 974975, MCL3A 01 G 25/09. Sprinkling unit/ MEM, Weedin and Ughanation (USSR). - Application No 2955078/30-15. Declared 11.07.1980. Publ. 23.11.1982. Bull. No. 43 // Opening. Of invention.-1982. No. 43).

The disadvantages described dual console farm, despite the goal, include low technical and operational reliability, high consumption of materials and the cost of the upper inflatable sleeve.

Also known irrigation machine comprising hinged on the vehicle dual console farm water conveyance belt which is provided with the water outlet sleeve, in which, to simplify design, is each console farm is equipped with a strained on its axis of symmetry by a rope, through a cranked nozzles fixed water outlet sleeve; elbows are pinned on the ropes and movably provided with clamps (SU inventor's certificate No. 1014531 And MCL3A 01 G 25/09.

Inner section of insert is equal to sections of pipes of V-shaped water passing member. Proposed two-cantilever self-aligning truss for sprinkling machines provides uninterrupted delivery of sprinkling water to short range heads of intermediate panels and long-range heads on guy part of truss.

EFFECT: reduced materials usage, improved sprinkling.

FIELD: agricultural engineering.

SUBSTANCE: invention relates to machines for mechanization of drop irrigation of crops. Proposed truss has upper and lower chords, central panel in form of regular pyramid with square base and left-hand and right-hand cantilevers mated with pyramid. Central panel has square base made of tubes with flanges for connecting lower chords and four suspensions orientated along ribs. Panel is provided with one post located on one of side faces along apothem of pyramid. Each cantilever consists of thirteen intermediate panel and one end panel. Each end panel is made up of two posts, one brace, two front and rear water tubes of lower chords, one upper chord, two tilted struts and two horizontal tension members. Two heads are fitted on each intermediate panel and end panel. End is made in form of guy-rope truss. It is mated with truss panel by brace and tilted posts. 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.
