Description

Technical Field

[0001] This utility model relates to a high-efficiency water-saving irrigation rotary sprinkler, belonging to the field of agricultural water conservancy engineering. Background Technology

[0002] The working principle of a rotary sprinkler head mainly relies on its internal mechanical structure and water flow dynamics. When water flows through the sprinkler head, a certain pressure difference is generated, which drives the internal rotating mechanism to start working. With a continuous supply of water, the sprinkler head will continuously rotate and spray water evenly, covering the entire irrigation area.

[0003] A Chinese invention patent with publication number CN112718280A discloses a multi-nozzle rotatable irrigation device for ecological agriculture. The device includes a rotating irrigation body with multiple sets of concealed protective spray components rotatably mounted on it. Each concealed protective spray component includes a nozzle protective shell, with multiple first connecting posts connected to the inner wall of the shell. Each first connecting post has a first nozzle groove. This invention, by setting a double concealed nozzle protection structure on the agricultural irrigation device, can conceal and protect the nozzles when irrigation is not needed, thereby preventing corrosion and damage from the external environment, extending the service life of the nozzles and related components. Furthermore, the two concealed nozzles can be opened separately; even if the nozzle of the outer nozzle becomes blocked, it will not affect normal irrigation. Simultaneously, the cleaning component of the inner nozzle can clean the blocked nozzle of the outer nozzle when it is opened, thereby reducing the user's maintenance costs and workload, and responding to the high-efficiency and water-saving concepts in ecological agricultural irrigation technology.

[0004] Traditional agricultural irrigation uses flood irrigation or sprinkler irrigation. These methods often cannot accurately control the spray range and intensity of water, resulting in a large amount of water being absorbed by the soil during irrigation and then quickly evaporating or seeping into the deeper soil layers, thus failing to be effectively utilized by crops.

[0049] The introduction of the excess water re-spraying part 14 makes the excess water remaining in the pipeline or assembly after the operation of the spraying assembly 1 be re-utilized and sprayed out through the nozzle hole 141, thereby avoiding the waste of water resources;

[0050] The cleaning part 142 and the cleaning hole 143 inside it are designed not only to provide a channel for the excess water re-spraying, but also to help physically clean the nozzle and the inner wall of the pipeline to a certain extent during the spraying process or the re-spraying, thereby reducing the accumulation of scale, impurities and other substances, maintaining the cleanliness and smoothness of the spraying assembly 1, and further enhancing the overall cleaning effect.

[0051] Through the synergistic effect of the excess water re-spraying part 14 and the cleaning part 142, the problem of nozzle blockage caused by long-term use is effectively reduced, and the service life of the spraying assembly 1 is prolonged.

[0052] Due to the design of the excess water re-spraying part 14 and the cleaning part 142, the user can more easily remove the remaining impurities and scale when maintaining the spraying assembly 1.

[0053] As shown in Figures 1 to 11 As an optimization, the main assembly 2 includes a base body 21, a six-way channel 211 is formed in the base body 21, the six-way channel 211 is connected with an excess water inlet adapter 23 and an excess water outlet adapter 24 at the top, the six-way channel 211 is connected with a control gas pipe 25 at the top, and a nozzle opening and closing control assembly 3 is slidably connected in the six-way channel 211.
