摘　　要：设计了结构紧凑、转向半径小的履带自走式果园定向风送喷雾机。对传动系统、履带行走系统和风送系统等关键部件进行了设计和计算,对定向喷雾机构进行了设计和试验验证。试验结果表明:有风送时雾滴沉积量比无风送时提高了42.9%,变异系数降低了18.5%;定向喷雾比普通喷雾雾滴个数提高了30.9%,变异系数降低了55.3%。A kind of self-propelled crawler directional air-blowing orchard sprayer was developed. The working principle and transmission line of the machine were introduced firstly. Adopting theoretical calculation, the design of whole structure and the technical parameters of the key components were determined. In order to achieve the directional spraying, the multi-degree of freedom framework was designed. The experiment showed that, compared with no wind spraying, the deposit rate of droplets increased by 42. 9% and the coefficient of variation decreased by 18.5%. Compared with ordinary spraying, the number of droplets increased by 30.9% and the coefficient of variation decreased by 55.3%.
