Technical Field

The invention relates to the technical field of agriculture, in particular to a spraying device for agricultural irrigation.

Background

Irrigation is a technical measure for supplementing the soil with the water needed by crops. In order to ensure the normal growth of crops and obtain high and stable yield, the crops must be supplied with sufficient moisture. Under natural conditions, the water requirement of crops cannot be met due to insufficient precipitation or uneven distribution. Therefore, irrigation must be done manually to compensate for the lack of natural rainfall. Irrigation, namely watering the land with water. The irrigation principle is that the irrigation quantity, the irrigation times and the irrigation time are determined according to the water requirement characteristics, the growth stage, the climate and the soil conditions of the medicinal plants, and the medicinal plants are irrigated in a proper time and in a proper amount and reasonably. The main types of the irrigation include irrigation before sowing, seedling-accelerating irrigation, growth period irrigation, winter irrigation and the like. Irrigation methods can be generally divided into traditional ground irrigation, ordinary sprinkling irrigation and micro-irrigation.

And ordinary sprinkling irrigation is because its lower cost is widely used, when using the sprinkling irrigation, generally all is a plurality of shower nozzles of even placing in the farmland, but present sprinkling irrigation equipment has certain problem, and when using, sprinkling irrigation equipment's range can't be adjusted by oneself for the irrigation water that sprays out is in a certain fixed area all the time, thereby makes the area of spraying of single shower nozzle very little.
