摘要：
The utility model refers to agriculture and can be used on hydraulically driven sprinklers moving around in a circle around a fixed support for the application of soluble fertilizers and other chemicals. The technical task of the utility model is to simplify the design and improve the reliability of the equipment for feeding fertilizers and reduce its cost, improve the operational performance of the technological capacity and improve the reliability of the sprinkler. A sprinkler, including a fixed support with a rotary knee and a butterfly valve, a conduit supported by self-propelled trolleys with hydraulic actuators, an additional polyethylene pipeline connected through a fine filter with a rotary knee to the disc gate and hydraulic drives of the trolleys, a technological tank for the preparation of a mineral fertilizer solution, characterized in that it is provided with an injector whose inlet hose is connected to a pipeline of a closed irrigation network to a hydraulic valve whose outlet hose is connected to the sprinkler line after the butterfly valve and the suction hose of the injector is connected to a sampling tube of the process vessel , in which an agitator with a barborator and hydraulic nozzles and a cleaning flange is installed. The advantage of the proposed sprinkler is that the process of introducing a solution of mineral fertilizers with irrigation water is simplified, since the injector is simple in design, reliable in operation and much less at the cost of the membrane hydrosparker. The introduction of a solution of mineral fertilizers with irrigation water is carried out with a low-pressure operation mode of the machine. The required head at the machine inlet is reduced to 0.35-0.4 MPa (instead of 0.5-0.7 MPa for series machines). An aggressive solution of mineral fertilizers only enters the pipeline of the machine, and only clean water enters the speed control mechanisms, hydraulic drives of the trucks and the hydroprotection of the machine, whic
