A novel vibration sieve based on the parallel mechanism
A new concept of vibration sieve based on parallel kinematic mechanism (PKM) is proposed in this paper and a novel 2-DOF spatial parallel mechanism is also designed here. The screen box fixed on the moving platform of the parallel mechanism poses an independent vertical translation and two rotations (one rotation is independent and the other is derivative). The trajectory of the screen-surface appears a serial of complex spatial curves, which is suitable for sieving materials effectively. A kinematics model for positive and inverse solution of the mechanism is also derived. According to the technical demands of the sieving, the dimensions of the links are designed, and the three-dimension solid model motion is simulated. Then, the track equation of points on the moving platform is deduced and the track curves are plotted using MATLAB. The prototype is manufactured at last. All these works provide a foundation for optimizing design of the technical parameters.
