摘要：
The proposed utility model relates to agriculture and can be used on non-electrified sprinkling machines moving in a circle using support trolleys driven by hydraulic cylinders. The technical task of the utility model is to obtain the possibility of increasing the water pressure at the end of the irrigation pipe of the Frigate type irrigation machine, moving in a circle with the help of hydraulic actuators, which will increase the area of rain irrigation with end sprinklers. It is slowed by the fact that a rocker is connected to the hydraulic cylinder of the hydraulic drive of the last bogie, the other end of which is connected to the pump piston, the inlet of which is connected to the sprinkler pipe of the machine through the check valve and the outlet, and the outlet through the check valve is connected to the pressure tank, the output of which is connected to the shutter blocking the pipeline, the output of which is connected to the end sprinkler. The damper is controlled (opens and closes) by means of a trigger device, which, in turn, is controlled by means of traction with the upper and lower stops and rocker arm, the latter is connected via a rod to a piston installed in the cylinder connected to the pressure tank. A spring is installed on the other side of the piston, the other half of which rests against the nut that limits the spring travel. The advantage of the utility model is that it will significantly increase the water pressure in front of the end sprinkler and thereby increase the irrigation area of the non-electrified Frigate type sprinkler including field angles not covered by rain cars. 2 ill.Предлагаемая полезная модель относится к сельскому хозяйству и может быть использована на неэлектрифицированных дождевальных машинах, перемещающихся по кругу с помощью опорных тележек, приводимых в движение гидроцилиндрами.Технической задачей полезной модели является получение возможности увеличения давления воды в конце поливного трубопровода дождевальной маш
