摘要：
The utility model relates to agriculture and can be used on hydraulic sprinkler machines moving in a circle. The technical task of the utility model is to increase the speed of the machine when operating at low pressure and to increase the reliability of the sprinkler. ； the main steel pipeline with a butterfly valve and sprinkler nozzles mounted on surface irrigation devices； self-propelled carts with hydraulic drives； an additional polyethylene pipeline connected to the rotary elbow of the machine to a disk shutter supplying water to the hydraulic actuators of the carts, characterized in that the hydraulic actuators of the carts of the middle and end parts of the machine are connected to the additional polyethylene pipeline, and the hydraulic actuators of the carts at the beginning of the machine are connected to the main pipeline, in addition, the first pipe of each span is equipped with a bracket with a spherical finger, and the pipe mounted on the trolley is equipped with an arm with a support in which the ball pin is mounted, and between the pipe mounted on the trolley and the first pipe there is a rubberized pressure hose connected by pipe clamps. The proposed utility model consists in the fact that when hydraulic carts of carts are connected to an additional polyethylene pipeline only in the middle and end parts of the machine, water consumption and pressure loss along the length of the polyethylene pipe are reduced, which increases the speed of the machine and the cyclicality of the last a single truck with a decrease in pressure at the inlet of the machine to 0.45 MPa. On the sprinkler machine, the reliability of work is also increased by reducing the breaks of gaskets and pipes, since bending on the spans occurs on flexible rubberized pressure hoses, and at the same time, the power loads on the pipes are reduced when offset trolleys. 2 ill.Полезная модель относится к сельскому хозяйству и может быть использована на дождевальных машинах с гидроприводом, пе
