Description

Technical Field

[0001] This utility model relates to the field of irrigation sprinkler technology, specifically to an adjustable irrigation sprinkler for farmland. Background Technology

[0002] In agricultural production, irrigation is a crucial link in ensuring crop growth. Reasonable and effective irrigation methods not only meet the water needs of crops but also conserve water resources and improve the economic efficiency of agricultural production. Many farmlands use irrigation sprinklers with fixed spray angles, which cannot be flexibly adjusted according to the terrain, crop planting layout, and the needs of different growth stages. Therefore, some new types of irrigation sprinklers have emerged on the market.

[0003] For example, Chinese Patent CN215582810U discloses a garden irrigation device with adjustable angle, comprising: a nozzle for spraying water; a connecting plate sleeved on the side of the nozzle; a mounting base provided on the side of the connecting plate, allowing the nozzle to be installed between the mounting base and the connecting plate; a connecting shaft connected to the bottom of the mounting base; and a support frame connected to the side of the connecting shaft, supporting the nozzle. In this garden irrigation device with adjustable angle, when the nozzle rotates to 360 degrees, the forward and reverse motors rotate in opposite directions, causing the nozzle to rotate in the opposite direction, facilitating adjustment of the spray angle. A locking rod can be reset by the spring's own elasticity, and after reset, it can engage with a locking groove for quick nozzle installation. When the bolt threads slide, they can compress and fix the support frame, facilitating quick fixation of the support frame during nozzle use.

[0004] The aforementioned patent provides an adjustable sprinkler irrigation device that is easy to fix quickly and the nozzle can rotate 360 ​​degrees. However, the nozzle of this type of sprinkler irrigation device cannot adjust the elevation or depression angle of the water flow according to usage needs, resulting in poor flexibility of use and hindering the efficient irrigation of farmland by workers.
