摘要：
The utility model relates to agriculture and can be used in irrigation equipment, namely on sprinkler machines moving in a circle around a fixed support. The technical task of the utility model is to increase the reliability and quality of watering the machine while reducing rain intensity, simplifying the design of surface irrigation devices and the process of regulating it in height with a simultaneous increase in the width of the arrangement of sprinkler nozzles. A sprinkler machine, including a fixed op ru, self-propelled carts with hydraulic drives, on which a pressure pipeline with a system of vertical and horizontal cables is mounted, characterized in that the surface irrigation device is made in the form of a pressure hose, which is connected through an adapter to a sprinkler nozzle with a “return cone” deflector and a filter with holes, moreover, the diameter of the filter holes is less than the diameter of the nozzle, in addition, the sprinkler nozzles in the first half of the machine pipe have an internal cylindrical cavity, and in the second half the machine’s water supply is an internal cylindrical cavity with a cone, the angle of which is 150 ... 160 °, the horizontal cable is also equipped with a bracket. The advantage of the proposed sprinkler is that the surface irrigation devices, thanks to the flexible pressure sleeve, provide easy adjustment of the installation height (from 0.7 to 2 , 2 m) irrigation nozzles as high-stemmed crops grow with a cable. At the maximum lifting height of the sprinkler nozzles, the distance between them along the line perpendicular to the pipeline increases to 3 m, which increases the width of the rain by 25%, as a result, the average rain intensity decreases and the irrigation rate to the drain increases. To give the required water flow in the first half of the machine’s pipeline , on sprinkler nozzles with an internal cylindrical cavity, it is necessary to increase by 15-20% the diameter of the nozzle having a low coef
