三、工作原理
该机主要有传动、摆动、振击、夹紧机构及电器等部件所组成。本机由动机通过主轴，（传动轴）带动齿轮，有蜗轮再带动凸轮，主偏心轴带动两个付偏心轴，从而使筛座具有回转及振击双重动运动。
III.Working principle
The machine is mainly composed of driving, oscillation, vibration and strik, clamping mechanism and electrical components. It is operated with motor to drive gear , worm wheel to drive cam and main eccentric shaft eccentric shaft to drive two auxiliary eccentric shafts through main shaft ,thereby allowing strainer seat to make dual movements of gyration and vibration and strike.
