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.
