The sprinkling irrigation for realizing nozzle one's own department or unit near zone, improves sprinkling irrigation coverage area, which improves nozzle radial direction by additional structure
Water distribution, but on nozzle jet break process without influence, influences the water distribution of nozzle low pressure operating mode less, can not achieve
The low pressure of nozzle is sprayed.
Chinese patent CN104050327A discloses " a kind of design method of low pressure nozzle variable speed mechanism ", is turned using becoming
Fast mechanism adjusting shower nozzle range, realizes the superposition of water distribution under different ranges, to improve the irrigation uniformity of nozzle.Adjusting is penetrated
The method of journey can improve nozzle irrigation uniformity, but under low pressure operating mode, and drop diameter problem bigger than normal can not solve.
Chinese patent CN105032639A discloses " a kind of low pressure nozzle of movable sprinkler irrigation ", using with multiple runners
Spray disk, and each portion of angle for spraying disk upper runner is identical, and the flow covering different zones that different runners spray is made to realize low pressure
The uniform sprinkling of nozzle, but use the sprinkler pattern range of spray dish structure shorter, the nozzle of Far Range in can not substituting.
Patent CN202762569U discloses " a kind of Rocker arm spray head ", is accelerated using the main burner and auxiliary jet of mesh
Jet crushing improves the water distribution of nozzle, but mesh nozzle can significantly reduce sprinkler pattern range, is improved compared to the uniformity
Degree, range influences sprinkler performance will significantly, therefore this method actual application prospect is poor.
The multipurposeization of spray irrigation system is mainly in the additional fertilising device for administration of drugs of irrigation system stem.Patent
No. CN104365255A discloses a kind of " water-fertilizer integral irrigation system ", and grug feeding jar and metering are devised in irrigation system stem
Fertilizer is pumped into irrigation pipe network using metering pump and realizes water and fertilizer synchronization by pump;Patent CN104025791A discloses " a kind of
Dissolved fertilizer is inputted spray drop according to preset flow using essence amount note fertilizer pump and fills unit by trickle irrigation liquid manure integral system ".But
Since irrigation system different zones irrigation quantity is not quite identical, resulting in different zones dose, there is also certain differences.
For the above deficiency, using a kind of internal-mixing structure, in spray irrigation system end, namely at spray outlet, design
Mixing arrangement, to realize the water-fertilizer integral of spray irrigation system, moreover it is possible to nozzle be made to become aqueous vapor dual-phase jet, water by single-phase water jet
After jet stream itself contains micro-bubble, before and after ejection, the change of volume occurs because of pressure change for bubble, to the broken of jet stream main body
It splits and has an impact, to improve the irrigation uniformity of low pressure lower nozzle.
