Its self-synchronous eccentric shaker

The present invention provides a self-synchronization shaker and eccentric. The eccentric mass comprising: a main eccentric, the eccentric mass comprising main sub eccentric mounting hole; eccentric sub, the sub-block movably mounted eccentrically in the eccentric mass sub-mounting hole; cap, cap lid in the sub-mounting hole and the eccentric mass connected to the main eccentric. When generating a phase angle difference between the two exciter, the sub-blocks may be substantially regarded as an eccentric energy store, the energy storage and release achieved by the sub eccentric block, so as to achieve stable operation that the eccentric mass of the object of the present invention , increase self-synchronizing shaker synchronization stability, and low cost.
