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 reduce labor costs when adjusting the installation height of the sprinkler of a surface irrigation device and to improve the quality of irrigation. the machine consists of a fixed support, a pressure pipe mounted on self-propelled carts with hydraulic drives. Surface sprinkling devices are mounted on the pipeline, consisting of a pressure hose, an adapter with an arm and a nozzle with a clamp. On the adapter of the surface sprinkling device, at the beginning of the machine, a sprinkler nozzle with a “return cone” deflector with a jet exit angle of 20 ° to the horizon is installed. Near-surface irrigation devices installed in the area of trolleys and in the second half of the machine are equipped with adapters with sector nozzles. The adapter is made at an angle of 45 °, which provides an angle of departure of the jet sector nozzle 15 ° to the horizon. A lever with a lock is installed on the nozzle with a lock. The irrigation nozzle with a “reverse cone” deflector is equipped with a load to ensure its vertical position during irrigation. The advantage of the proposed irrigation machine is that the surface irrigation devices provide easy adjustment of the installation height of sprinklers from 0.8 to 2.5 m, as the tall stems grow crops, while reducing water loss by evaporation and drift, and increases the uniformity of irrigation in the wind. Improves the reliability of the surface irrigation device for Thu drain water after watering and lack of destruction of iron angles. Sector nozzles in the area of trolleys provide watering in the direction opposite to the movement of the machine, which reduces the ingress of water under the wheels of the trolleys, reduces the track depth after irrigation and does not cause them to skid. This reduces the intensity of rain and increas
