Problems solved by technology

However, micro-sprinkler irrigation and drip irrigation also have certain limitations. Common micro-sprinkler irrigation and drip irrigation devices have limited irrigation range, high operating costs, high labor consumption, and low irrigation efficiency.
Existing micro-sprinkler irrigation devices still have many problems such as single function and poor adaptability.
For micro-irrigation of field crops, a complete irrigation system needs to be set up, the installation and operation are complicated, and the cost of facilities and equipment is high
Ordinary sprinkler irrigation technology has been widely used in agricultural production and landscaping irrigation, but in the process of use, it is found that the key scientific problems that need to be solved by sprinkler irrigation technology are: ⑴The impact of wind is relatively large, and the scope of popularization and application is greatly limited : The main reason is that the existing sprinkler irrigation equipment is fixed, and the occurrence of strong winds is random. It is proposed in the sprinkler irrigation technical specification that if the wind speed exceeds level 3, it is not easy to use sprinkler irrigation technology, so it brings a lot of trouble to the sprinkler irrigation implementers
At the same time, in the process of sprinkler irrigation, it is also found that most users do not strictly follow the wind speed requirements, resulting in a very serious drift loss of spray droplets during the spraying process, which makes the water use efficiency of sprinkler irrigation technology low
(2) Spraying uniformity is poor when multiple nozzles are used in combination: Spraying uniformity is an important parameter in the design of sprinkler irrigation systems and an important indicator to measure the irrigation quality of sprinkler irrigation systems. It has an important impact on sprinkler irrigation system investment and crop yield and quality
Under certain meteorological conditions, the uniformity of sprinkler irrigation water distribution on the field surface is mainly affected by four aspects: ①The working pressure of each sprinkler in the field is inconsistent due to the loss of pipeline water head and the terrain height difference, that is, the deviation of the working pressure of the sprinkler; The water volume of a single sprinkler caused by its own hydraulic performance is unevenly distributed on the surface; ③ Due to the difference in the spacing and combination of nozzles, the superimposition of the spraying water volume of two adjacent sprinklers is different, which will also affect the distribution of spraying water volume; ④ The terrain slope affects the water volume of a single sprinkler. The impact of distribution
(3) The operating cost of the current sprinkler irrigation technology is relatively high: the investment in the field pipe network of the sprinkler irrigation system is closely related to the uniformity of sprinkler irrigation, and the system investment increases with the increase of uniformity, especially when the uniformity of sprinkler irrigation is greater than 90%, the uniformity increases slightly Will lead to a sharp increase in system cost
However, in this invention, there is no integration of fixed and automatic control irrigation devices.
At the same time, the use of diesel engines to drive sprinkler irrigation and drip irrigation systems consumes more fuel and causes great pollution to the environment.
