SPRINKLING ATTACHMENT Russian patent published in 2015 - IPC B05B1/26 A01G25/00 

FIELD: agriculture.

SUBSTANCE: sprinkling attachment includes the pressure head pipeline (1) with the nozzle (2), deflector (9), designed as a cone, vertical axle (6) and swing arm (3), fixed by nut (4) on the pipeline (1). In the upper part of the deflector (9) there is a cylindrical shank with a blind vertical hole, by means of which the deflector (9) is placed with a possibility of movement on the lower end of the vertical axle (6). In the middle of the vertical axle (6) the stop (8) is rigidly fixed, between the stop (8) and the deflector (9) the spring (10) is installed which tends to press the deflector (9) walls to nozzle (2) walls. The upper end of the vertical axle (6) is equipped with the handle (7), between the handle (7) and the stop (8) on the vertical axle (6) a thread is made, due to that the vertical axle (6) rotates in the vertical sleeve (5), with inner thread and rigidly fixed in the upper part of the swing arm (3).

EFFECT: ensuring the adjustment of radius of watering and sprinkling attachment for operation with various pressures of supplied water, avoidance of leak of overfilled water through nozzle edges at significant pressure drop, that allows to avoid erosion of fertile layer of soil in the location of the sprinkling attachment.
