3WFQ—1600型牵引式风送喷雾机研制与试验

因现代新型果园的种植模式及管理特点,小型的喷药植保机械不能满足新型果园的植保要求。为此,研制了3WFQ—1600型牵引式风送喷雾机。该机在隔膜泵和风机变速箱之间加装了联轴器,动力通过联轴器传递,优化了整机结构。通过理论计算完成了喷雾部件的选型,设计了R级风机流道结构和风机变速箱,风机叶轮直径1.0 m,叶片数为14,风机变速箱有高低两个挡位,其传动比分别是1:3.7和1:4.6,实现了风机转速0~2 0 0 0 r/min和0~2 5 0 0 r/min的无级变速。借用Inventor软件的实体建模功能,完成了喷雾机整机的设计装配。室内试验和样机的田间试验表明:风机转速达到1 500r/min时,风机两侧14个测试点的平均风速为16.3m/s,风量为12.8m~3/s,雾滴密度合格率为9 8.6 1%。

Design and Experiment of 3 WFQ-1600 Traction Type Air-assisted in Orchad

According to the characteristics of the modern new orchard planting pattern and management, small spraying plant protection machinery cannot meet the requirement of the plant protection of new gardens. As a result, the traction type air-assisted of 3WFQ-1600 was developed to solve similar problems. Between the diaphragm pump and fan gearbox of this machine is a coupling, and the power is transmitted through the shaft coupling ,which optimize the structure of the whole machine. Through the theoretical calculation of finished spray parts selection, rated R fan flow channel structure and fan gearbox were designed ,the diameter of fan impeller is 1. 0 m and blade number is 14. Turbine gearbox has high and low two gears, the transmission ratio are 1:3. 7 and 1:4. 6, achieving the fan speed 0~2000r/min and 0~2500r/min. To complete the spray machine design and assembling of the machine, we used the AIP software entity modeling ca-pabilities. The field test and indoor test shows that when the fan rotation speed reaches 1500r/min, 14 test points of the fan on both sides of the average wind speed is 16. 3m/s, air volume is 12. 8m/s, drop density percent of pass is 98. 61%.
