Technical Field

[0001] The utility model relates to the field of manufacturing agricultural irrigation equipment, in particular to an agricultural irrigation sprinkler head. Background Technique

[0002] Sprinkler irrigation is an irrigation method that has been used for a relatively long time in agricultural irrigation. Whether using a micro-sprinkler belt for irrigation or a sprinkler head for sprinkler irrigation, the irrigation water falls from the air onto the crop leaves and the soil like rain. Compared with other irrigation methods, sprinkler irrigation has a high irrigation uniformity, strong controllability, and can provide irrigation water for crops in a timely and appropriate amount. By reasonably controlling the irrigation time, deep percolation and surface runoff can be avoided, water and fertilizer loss can be reduced, and the utilization rate of water and fertilizer can be improved. Moreover, sprinkler irrigation will not damage the soil structure in the field and can also improve the microclimate in the field, which is very beneficial to the growth of crops.

[0003] Currently, the commonly used sprinkler heads are mainly divided into three categories: large sprinkler heads, medium-sized sprinkler heads, and micro-sprinkler heads. When these three types of sprinkler heads are used alone, it is difficult to take into account crops of different heights and densities, and problems such as over-irrigation or under-irrigation often occur.
