中文摘要:
      为了解决藜蒿(Artemisia selengensis)人工去叶效率低和成本高的问题,设计了一种气吸式藜蒿去叶机。对气吸式藜蒿去叶机的自动开合夹、自动去叶组件等关键零部件进行设计,并对相关运动参数进行分析,得到各部件之间的运动关系式。试制样机并进行试验分析,通过正交试验得出最佳运动参数为:自动开合夹移动速度为0.120 m/s、凸轮转速为50 r/min、轴流风机风压为100 Pa;样机在此最佳参数下的实验结果表明,该气吸式藜蒿去叶机工作时对藜蒿的夹取率为98%、去叶合格率为89%,具备较好的实用性。
英文摘要:
      A kind of air suction type Artemisia selengensis leaves removing machine was designed to solve the problems of low efficiency and high labor cost of artificially removing leaves of A. selengensis,which consists of the transport part and removing leaves part. Automatic opening and closing clips,automatic removal of leaf components and other key components were designed. The relevant motion parameters were analyzed to obtain the motion relation between the components. The prototype was manufactured and tested with orthogonal test. The optimal motion parameters of the prototype obtained are as follows:the speed of the automatic opening and closing clip is 0.120 m/s,the cam speed is 50 r/min,and the axial pressure of the axial fan is 100 Pa. Results showed that the entrainment rate of the machine was 98% and the qualified rate of removing leaves was 89% with a good practicality. It will provide a new direction for the studies on removing A. selengensis leaves mechanically.
