MULTI-SECTION SPRINKLING MACHINE OF A CIRCULAR ACTION Russian patent published in 2018 - IPC A01G25/09 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture and can be used for irrigation of crops by sprinkling. A multi-section sprinkling machine of circular action contains a central fixed support with a rotary knee, successively connected sections of the pipeline, sprinkler nozzles placed on the pipeline. Each section of the pipeline is made in the form of a three-dimensional truss. End of the pipeline section is placed on a self-propelled cart. Trolley has a drive from the electric motor and the control unit. Second end of the section is connected to the previous section of the pipeline by means of a pivot joint of the cardan type. Cavities of adjacent sections are connected by means of clamped rubber clutches. Each rubber coupling is made of reinforced rubber in the form of corrugation. At the ends of the corrugations have sockets. Inner part of one of the funnels is made in the form of a cylindrical shielding pipe. Branch pipe passes through the entire cavity of the coupling. Free end of the shielding pipe is displaceable in the direction of flow of water in the cavity of the next section of the pipeline.

EFFECT: uniformity of watering of the peripheral region of the irrigated area is achieved; it is possible to irrigate areas with large differences in altitude and slopes of the terrain; the time and costs for preparing and putting irrigated plots in operation are reduced.
