Embodiment Construction

[0014] Such as figure 1 , 2 , 3, the present invention includes a nozzle 1, an inlet pressure regulator 2, an outlet pressure automatic regulator 3, a nozzle 4, a spring 5, a nozzle 6, and an elastic flow channel 7. The elastic flow channel 7 is a shrinkable conical shape, and its outlet diameter is 1 / 5 to 1 / 3 times of the inlet diameter. Sealing means. The nozzle 6 is an open conical cylinder, the bottom of the conical cylinder of the nozzle 6 is fixedly connected to one end of the nozzle 4; the elastic flow channel 7 is built inside the nozzle 6, and the built-in elastic flow channel 7 is connected to the inner wall of the nozzle 6 by a spring 5 , the spring 5 is located at 1 / 3 and 2 / 3 of the length of the nozzle 6, the spring 5 and the nozzle 6 are processed as one, and three springs 5 ​​are evenly arranged on the cross section of each nozzle 6, the purpose of which is to make the elastic flow The stress of road 7 compression springs 5 ​​is even. The elastic flow channe...

Abstract

The invention relates to an automatic outlet pressure regulating device for a variable sprayer, which is capable of realizing variable spraying and comprises a spray pipe, springs, nozzles and an elastic runner, wherein the elastic runner is fixedly connected with the spray pipe, a sealing device is arranged at the joint of the elastic runner and the spray pipe, the elastic runner is internally arranged inside the nozzles and forms a certain contracting angle, and the internally arranged elastic rubber is connected with the inner wall surface of each nozzle through the springs so that the springs compressed by the elastic rubber are uniform in stress. The automatic outlet pressure regulating device is simple in structure, reliable in operation and high in operability, the nozzles of the sprayer are automatically adjustable in size, and the sectional area variation of each nozzle outlet is as same as that of an inlet pressure regulating device in proportion, so that spraying uniformity of the variable sprayer is improved.

Description

technical field [0001] The invention relates to a key equipment in a water-saving irrigation sprinkler irrigation system, which is suitable for a rotary sprinkler whose working pressure changes with time during spraying, and improves the uneven distribution of sprayed water caused by pressure changes, in particular to a variable sprinkler outlet Automatic pressure adjustment device. Background technique [0002] At present, "precision agriculture" and "variable technology" have become the development direction of agricultural engineering research and application. And its core technology is to be able to develop equipment that can irrigate different amounts of water at different locations according to the needs of crops and plot shapes. In the prior art, a pressure regulating device is installed at the inlet of the nozzle to change the flow area of ​​the inlet to realize non-circular spraying area spraying. During the rotation of the nozzle, the function of the inlet pressu...
