摘要
针对现代果园低矮密植的种植特点,设计了3WZ-700型自走式果园风送定向喷雾机。通过理论计算和虚拟样机技术,完成整机结构设计和各关键部件技术参数的确定。设计了适应于低矮密植果园的圆环双流道风送雾化装置,确定叶轮直径0.7 m、出风口宽度0.13 m。实现风机转速0～2 000 r/min的无级变速。田间试验结果表明,树膛内部枝叶正、反面雾滴附着率分别为61.22%、20.90%;树膛外部枝叶正、反面雾滴附着率分别为77.22%、37.17%;作业效率为1.02 hm2/h。
According to modern orchard planting pattern,a kind of self-propelled air-blowing orchard sprayer was developed.Adopting theoretical calculation and virtual prototype technology,the whole structure design and the key components technical parameters were determined.A ring fan was designed for modern orchard.The impeller was 0.7 m and outlet width was 0.13 m.The step-less transmission of fan was accomplished from 0 to 2 000 r/min.The field experiment showed that the front deposition reached to 61.22% and other side reached to 20.90% inside the trees.In the surface of the trees,the front deposition reached to 77.22% and other side reached to 37.17%.The operation efficiency reached to 1.02 hm2/h.
