MULTI-SECTION CIRCULAR SPRINKLING MACHINE Russian patent published in 2022 - IPC A01G25/09 B05B1/18 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture. The circular sprinkling machine contains a central fixed support with a swivel knee, sprinkling nozzles placed on series-connected sections of the pipeline, each of which is made in the form of a three-dimensional truss. One end of the pipeline section is placed on an intermediate self-propelled trolley, and the other end is connected to the previous pipeline section by means of a cardan-type swivel joint. On sections of the pipeline there are sprinkling nozzles 2.9-3.5 meters apart from each other of different design types and having a different nozzle flow area, increasing from 3 to 15 mm. On the sprinkling machine with a length of one to three sections, sprinkling nozzles are installed with a nozzle flow area from 3 to 10 mm, having a smooth deflector. The sprinkling machine with a length of three to six sections is equipped with sprinkling nozzles with a nozzle flow area from 3 to 10 mm and having a smooth deflector from the first to the third sections and with a nozzle flow area from 10 to 12 mm and having a deflector with grooves on the sections from the fourth to sixth. On a sprinkling machine with a length of six to ten sections, sprinkling machine nozzles are installed with a nozzle flow area from 3 to 10 mm and having a smooth deflector from the first to the third sections, with a nozzle flow area from 10 to 12 mm and having a deflector with grooves on sections from the fourth to the sixth and with a nozzle flow area from 12 to 15 mm and a rotating deflector on sections seven to ten. On a sprinkling machine with a length of more than ten sections, sprinkling machine nozzles are installed with a nozzle flow section from 3 to 10 mm and having a smooth deflector on sections from the first to the third, with a nozzle flow section from 10 to 12 mm and having a deflector with grooves from the fourth to the sixth sections and with a nozzle flow area from 12 to 15 mm and having a rotating deflector on sections from the seventh to the tenth and with a nozzle flow area of ​​15 mm, having a cascade deflector on sections from the eleventh or more. Sprinkling machine nozzles with a cascade deflector are installed on the sprinkling machine when irrigating at rates of more than 500 m3/ha on any section of the pipeline with a nozzle diameter of more than 15 mm, and at the same time, the radius of the nozzle and the hole in the sprinkler nozzle deflector have a ratio of 1:0.7.

EFFECT: expansion of operational capabilities of the sprinkling machine, quality and uniformity of irrigation, reduction of rain intensity, reduction of water erosion of soils, improvement of the quality of machine operation.
