MULTISECTIONAL CIRCULAR SPRINKLING MACHINE Russian patent published in 2021 - IPC A01G25/09 B05B1/18 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture and can be used for irrigation of crops by sprinkling. The multisectional sprinkling machine is comprised of a central fixed support with a turn elbow, sprinkler nozzles placed on the pipeline sections connected in series, wherein each of the pipeline sections is made in form of a three-dimensional truss. One end of the pipeline section is placed on an intermediate self-propelled carriage, and the other end is connected with the previous pipeline section by means of a cardan-type hinged connection. Sprinkler nozzles of different structural types depending on the total length of the pipeline of the machine, with a different nozzle flow section increasing from the beginning to the end of the pipeline of the machine are placed on the pipeline sections. On a sprinkling machine with the length of no more than 300 m, sprinkler nozzles are installed on the first pipeline section of the sprinkling machine at a distance of 5 to 6 m from each other with a nozzle flow section of 3 mm and on subsequent spans at a distance of 2.9 to 3.5 m from each other with a nozzle flow section of 4 to 10 mm, equipped with a smooth deflector. On a sprinkling machine operating at a wind regime of more than 2.5 m/s, nozzles are installed on the first pipeline section of the sprinkling machine, equipped with a deflector with grooves, at a distance of 5 to 6 m from each other with a nozzle flow area of 3 mm, and on subsequent spans, nozzles are installed, equipped with a deflector with grooves, at a distance of 2.9 to 3.5 m from each other with a nozzle flow section of 4 to 10 mm.

EFFECT: improved quality and uniformity of irrigation, reduced sprinkling intensity and reduced water erosion of soil are ensured.
