Abstract

The invention provides an impeller-driven rotary nozzle and a rotation speed adjusting method thereof. The impeller-driven rotary nozzle comprises a damping device, a rotating body, a nozzle and an impeller, wherein the nozzle is mounted on a support frame; one end of the rotating body is rotatably mounted on the nozzle; the impeller is arranged on the rotating body and drives the rotating body torotate through the nozzle; the other end of the rotating body is rotatably mounted on the support frame; and the damping device is arranged between the rotating body and the support frame and used for adjusting the resistance of the rotating body in the rotation process. The impeller-driven rotary nozzle can solve the key technical problems that a rotary spraying element is complex in structure,hydraulic performance parameters are not easy to adjust, energy consumption is high, and work is not stable enough, and has the advantages of simple product structure, low energy consumption, reliableoperation and the like.

Description

technical field [0001] The invention relates to the technical field of agricultural water-saving irrigation, in particular to an impeller-driven rotary nozzle and a method for adjusting its rotation speed. Background technique [0002] The rotary sprinkler element is the key equipment in the sprinkler micro-irrigation system. Its performance directly affects the irrigation effect. Currently, the widely used rotary sprinkler element equipment has the following shortcomings in application. The spray element equipment achieved It is not easy to adjust the important hydraulic performance, such as rotation speed, spraying range, spraying uniformity, spraying water droplet size and other parameters; the structure of the driving parts of the rotary spraying element is relatively complicated, and it is necessary to overcome various problems in the process of realizing the rotation. Only this kind of resistance can complete the spraying, resulting in high energy consumption. Therefo...
