SPRINKLER Russian patent published in 2009 - IPC A01G25/09 

FIELD: agriculture.

SUBSTANCE: sprinkler includes irrigating pipeline, made in sections and equipped with spraying headers, wheel supports, drive gear, arranged in the middle of the central section and sections coupling elements. Irrigating pipeline is fixed on the arms of driving trucks and wheel supports, set on the inter-row spacing of the seeding of agricultural crops at the height of 2.0-2.5 m above the ground surface. Arm of the central driving truck has an offset forward turning triangle lead for fixation of tie-rods, connected with the arms of the driving trucks and supporting wheels of lateral sections. On the central truck there is a geared motor, which is intended for torque transmission from the motor to driving trucks by means of transmission shaft arranged on overhung bearings. Trucks wheels are driven by means of chain gear. Bypassing tubes are coupled to the irrigating pipeline by means of steering sleeves from the side opposite to the movement direction of the sprinkler. Tubes length equals diametre of supporting wheels of driven trucks; headers are set on hoses and resting against the ground. Case of the header is made of a long-wearing material and inside the internal cavity there is a flow guide having internal lead bar with left-side coiling and alternating pitch. Behind the lead bar there is a guiding paraboloid of rotation connected with outlet openings normally arranged to the axial line of the header, made at a tangent to the internal hole of the flow guide and directed counterclockwise. Whereat water outlet openings are directed upward and sideward.

EFFECT: increased duration of high productivity and improved operational capacities.
