农药的喷施质量在农业生产中极为重要，评价农药喷施质量的重要指标是农药有效物质在喷施靶标上的均匀沉积分布，其前提条件是农药有效物质与载体从喷洒部件喷出前就要搅拌均匀。针对邯农－６５０型大田喷杆式喷雾机的药箱，对影响搅拌效果的动力学因素及药箱充满程度进行了研究。结果表明，当其他参数确定后，加大搅拌压强或流量，搅拌效果都明显改善，但加大流量比加大压强的效果要好；药箱中药液装得越满，越易搅拌均匀，充满程度越小，越不易搅拌均匀。
The spraying quality of pesticides is extremely important in agricultural production. An important indicator to evaluate the spraying quality of pesticides is the uniform deposition distribution of pesticide active substances on the spraying targets, provided that the pesticide effective substances and the carrier are sprayed from the spraying components Stir well. Aiming at the medicine box of Hannong -650 field spray bar spray sprayer, the dynamic factors affecting the stirring effect and the filling degree of the medicine box were studied. The results show that when the other parameters are determined, the agitation pressure or flow rate is increased greatly, but the agitation effect is obviously improved. However, the effect of increasing the flow rate is better than increasing the pressure. The more filled the medicine liquid cartridge is, the easier it is to stir and fill The smaller the degree, the less likely to mix well.
