the utility model relates to a from spray nozzle who takes the wind wall effect in agricultural spraying, concretely relates to drift spray nozzle is prevented to toper wind field formula.

Background art:

the pesticide drift is a main factor causing liquid medicine waste and environmental pollution, and is also an important index for measuring the spraying effect. The related data show that the loss of yield can be recovered by 10-20% when the crops are subjected to disease, pest and weed control, but in practice, only a few parts of sprayed pesticides can reach targets to be controlled. Foreign scholars estimate that only 25-50% of the pesticide sprayed out of the pesticide application instrument can be deposited on crop leaves, wherein less than 1% of the pesticide can be deposited on target pests, and the pesticide amount which can really play a role of killing pests is less than 0.03%.

China is one of the countries with the largest production quantity and usage amount of pesticides in the world, and the usage amount of pesticides in 2009 in China is 128 ten thousand tons. Because the prior pesticide applying apparatus and pesticide applying technology in China are relatively lagged behind, the traditional spraying system has the main defects that the drifting phenomenon is serious, 70-80% of the sprayed pesticide is lost to the surrounding environment such as air, soil, a water system and the like, a large amount of pesticide is wasted, sensitive crop phytotoxicity, human and livestock poisoning and environmental pollution are caused, and the working quality of agricultural pesticide application is reduced to a certain extent. People and animals are poisoned by pesticide and medical instruments for tens of thousands of times each year in China, and a considerable part of the poisoning is caused by 'drift poisoning'. Therefore, for economic, environmental and safety reasons, there is a need for a spray system having improved drift prevention properties that minimize the amount of drift.
