Description
Technical field
The present invention relates to the calculation method in relation to straight movement type irrigation sprinkler performance parameter, especially a kind of straight movement type irrigation sprinkler is not
It is averaged the optimization method of application rate of sprinkler irrigation with combination spacing.
Background technique
Straight movement type irrigation sprinkler is a kind of typical sprinkling irrigation equipment, and the combination spacing of straight movement type irrigation sprinkler upper nozzle directly affects
To its application rate of sprinkler irrigation, the more close then application rate of sprinkler irrigation of the combination spacing of spray head is higher, otherwise the combination spacing of spray head the wide, sprays
Intensity is lower.Therefore, the setting of straight movement type irrigation sprinkler spray head combination spacing is the key that guarantee that it effectively runs.
With the development of science and technology with produce actual needs, straight movement type irrigation sprinkler is rapidly developed in various countries, but for
The calculating of straight movement type irrigation sprinkler application rate of sprinkler irrigation is also studied less.Straight movement type spray is effectively still calculated without a kind of in current existing research
Filling machine various combination spacing is averaged the calculation method of application rate of sprinkler irrigation, if being applied to farmland in certain special circumstances straight movement type irrigation sprinklers
When causing rainwash under irrigation, lack to relationship between the combination spacing setting of straight movement type irrigation sprinkler and average application rate of sprinkler irrigation
Solution and grasp, cannot directly analyze its whether the combination spacing of spray head be arranged it is unreasonable due to caused by, thus nothing
Method targetedly solves such study a question.Therefore, anomaly between a kind of straight movement type irrigation sprinkler various combination is developed
The calculation method of equal application rate of sprinkler irrigation, has highly important theory and practice meaning.
Summary of the invention
It is averaged application rate of sprinkler irrigation the technical problem to be solved in the present invention is to provide a kind of straight movement type irrigation sprinkler various combination spacing
Optimization method, with overcome to straight movement type irrigation sprinkler spray head combination spacing setting the problems such as study when, lack to straight
Line irrigation sprinkler combination spacing is arranged the grasp of relationship between average application rate of sprinkler irrigation and to problems can not be directed to
The solution of property.
Based on above-mentioned purpose, it is averaged the excellent of application rate of sprinkler irrigation the present invention provides a kind of straight movement type irrigation sprinkler various combination spacing
Change method, including the following steps:
(a) firstly, the operating pressure of setting straight movement type irrigation sprinkler upper nozzle, makes straight movement type irrigation sprinkler be maintained at steady operation
State, rain gage bucket a that water inlet diameter is D are disposed at spray head work, for measuring the water-spraying amount of single nozzle.It examines
Consider the case where spray head work when work just starts on translation type sprinkler may be not sufficiently stable, needs in setting operating pressure
Start measurement acquisition test data after lower steady operation 10 minutes or more again.Time of measuring s is set, test measurement obtains single spraying
Water-spraying amount b received by the range R and each rain gage bucket of headi(i=1 ... a).It repeats to test under the same test conditions
