众所周知,采用喷灌装置灌溉时雨滴分布的均匀性在很大程度上取决于风速。例如,当风速在3～8米/秒时,远射程喷灌装置的灌溉面积范围将减小30～60％。在苏联南部地区大风和恒风期约占作物生长期的50～60％,研制一种抗风的喷射装置显然是十分必要的。全苏农业机械制造科学研究所进行的研究表明,喷咀对地平面的倾角随着风力的增加将较原来最适宜的倾角有所减小,并与风向无关[参考文献 It is well-known that the uniformity of raindrop distribution when irrigating with sprinklers depends very much on the wind speed. For example, when the wind speed is between 3 and 8 m / s, the irrigation area of ​​the long range sprinkler will be reduced by 30-60%. In the southern part of the Soviet Union the gale and the constant wind account for about 50-60% of the crop growth period. Therefore, it is obviously necessary to develop a wind-resistant spray device. Research carried out by Quanzhong Agricultural Machinery Manufacturing Research Institute shows that the inclination of the nozzle to the ground plane will decrease with the increase of the wind force more than the most suitable inclination angle and has nothing to do with the wind direction [References
