根据当前林果病虫害防治的需要,针对现有喷枪存在的缺点,河北省永清县森防站、河北省森防站和林业部科技情报中心等单位组成了高效多用喷枪研制组。通过测试分析研究了国内农林病虫防治使用的小型可调喷枪和日本长杆可调式喷枪的性能及其优缺点,先后设计制造了4种高效多用可调式喷枪。经过反复试验、对比,以球面喷嘴的喷枪性能最好。在此基础上研制出能与多种动力机具配套,一枪多
According to the current needs of the prevention and control of fruit and vegetable diseases and pests, aiming at the shortcomings of the existing spray guns, units such as Forest Prevention Station of Yongqing County of Hebei Province, Forest Prevention Station of Hebei Province and Science and Technology Information Center of the Ministry of Forestry have formed a group of high-efficiency multi-purpose spray guns. Through testing and analyzing the performance, advantages and disadvantages of small adjustable spray gun and Japanese long rod adjustable spray gun used in pest control of agriculture and forestry in our country, four kinds of highly efficient and versatile spray guns have been designed and manufactured successively. After repeated tests, compared to the best performance of the spherical nozzle spray gun. On this basis, developed with a variety of power tools, more than a gun
