Abstract
A two-plate sand comprises a housing, an electric motor, two driving devices symmetrically arranged at two sides of the electric motor and driven by the electric motor and two sand plate components separately communicated with the two driving devices, wherein, two eccentric counter drive shafts are separately extended flexurally downwards from one end of each main drive shaft where the two driving devices are arranged symmetrically and the two eccentric counter drive shafts are separately communicated with the two sand plate components. The two eccentric counter drive shafts rotate in an opposite way eccentrically to the individual main drive shaft, resulting in opposite reciprocating motion of the two sand plate components at the effect of a restraint component arranged in the housing. In this way, it reduces the inner space of the whole driving devices, decreases weight of the complete apparatus and the opposite reciprocating motion of the two sand plates balances the inertia force and reduces vibration of the whole two-plate sand.
