FRAMEWORK OF BOOM-TYPE SPRINKLER OF DRUM-TYPE FLAT IRRIGATION Russian patent published in 2009 - IPC A01G25/09 

FIELD: agriculture.

SUBSTANCE: framework includes support sledge, central part, right and left consoles consisting of panels pin connected in the lower and upper belts. Water feeding belt is made of polyethylene pipes, metal corrosion-resistant branches with ribbed ring-surface compressed into the ends whereof, with flanges on the one end, in the one whereof there is a self - compacting packing. Polyethylene tubes are arranged inside lattice framework, length whereof equals that of the length of the panel. Vertical stability of the case frame is ensured by spreaders, cross stays and stands. Horizontal stability in the central part of the case and of the panel adjoining thereto is secured by the frame structure of alternating section. Horizontal stability of the rest of the panels is ensured by the case fame. Sprinkling working elements are made as deflectors with flat flame of the directed action and are arranged in the water feeding belt in pairs asymmetrically at a bent angle of the flame to the horizon of 7-15°.

EFFECT: increased duration of useful life and safety of agricultural technological process reduced hydraulic losses in water feeding pipelines and improved quality of artificial rain.
