TURBINE TYPE SPRINKLER Russian patent published in 2019 - IPC A01G25/02 B05B1/18 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to sprinkling irrigation equipment. Turbine-type sprinkler consists of housing, nozzle, deflector and counterweight. Housing is made with pipeline in center. Pipeline has thread in its upper part. Support ring is fixed in case by means of conical nozzle. Bushing is rigidly connected with support ring by means of jumpers. Vertical axis is installed in the bushing with possibility of rotation. Vertical axis is fixed on bushing by means of magnetic thrust bearing. Bearing consists of two annular permanent magnets facing each other with the same poles. First annular magnet is fixed on the upper end of the bushing. Second annular magnet is fixed on the collar of the vertical axis. Collar is formed by flow divider made in upper part of vertical axis. Deflector is rigidly fixed at an angle to the horizontal plane on the lower end of the vertical axis. Deflector is made in the form of a concave bowl directed towards the nozzle with an elevation in the center in the form of a truncated cone. On the deflector working surface there are helical grooves. Counterweight is installed on the body. Counterweight is made in the form of a streamline disk.

EFFECT: providing unobstructed water spraying in all directions at different angles to the horizontal plane; higher uniformity of moisture distribution and quality of irrigation.
