| 针对矮砧密植型果园喷药机作业过程中雾滴飘移、果树表面雾滴沉积量小的问题，设计了一种喷杆式喷雾系统。依据我国标准化果园参数，基于Fluent软件对药箱与喷杆、喷头与喷杆不同连接结构进行仿真分析，针对不同作业参数对果树表面雾滴沉积量的影响进行仿真试验，确定了最佳结构及最佳作业参数。仿真结果表明粗-细管径连接、喷头直接与喷杆连接距离40mm为最佳的连接结构；喷雾系统参数对果树表面雾滴沉积量影响主次关系为喷雾角度、喷雾距离、喷雾压力，得出最优解为喷雾距离1.32 m，喷雾压力1.19 MPa，喷雾角度110°，该作业参数下果树表面雾滴沉积量最高，为0.55 L。在果园进行实地试验表明，该喷杆式喷药机喷雾系统结构合理，满足标准化果园的植保作业需求。 |

| In order to solve the problems of droplet drift and small amount of droplet deposition on the surface of fruit trees during the operation of low anvil and dense planting orchard sprayer, a spray-rod sprayer system was designed. According to the standardized orchard parameters in China, the different connection structures of medicine box and spray rod, sprinkler head and spray rod were simulated and analyzed based on Fluent software, and the influence of different operation parameters on the deposition amount of droplets on the surface of fruit trees was simulated, and the optimal structure and operation parameters were determined. The simulation results show that the best connection structure is coarse-fine pipe diameter connection and the distance between nozzle and spray rod is 40mm. The main and secondary relationships of the effects of spraying system parameters on the amount of droplets deposited on the fruit tree surface are spray Angle, spray distance and spray pressure. The optimal solution is obtained as spray distance 1.32m, spray pressure 1.19MPa and spray Angle 110°. Under these operating parameters, the amount of droplets deposited on the fruit tree surface is the highest, which is 0.55L. Field tests in orchards show that the structure of the spray system is reasonable and can meet the needs of plant protection in standardized orchards. |
