The present invention discloses aUsed for materialsMaterial screening and impurity removalAnd other similar fields of vibrating screen machinesNew type of counterweight device，the aforementionedThe new counterweight device has two parts and is installed at both ends of the vibration motor shaft. Both parts have a fixed base consisting of a fixed base, a disc, and a limit ring. Both parts have limit blocks installed on the inner and outer edges of the limit ring, respectively. Both parts have an inner eccentric plate and an outer eccentric plate. One end of the inner eccentric plate and the outer eccentric plate is installed on a fixed base and can rotate around the axis of the fixed base. The other end of the inner eccentric plate and the outer eccentric plate are respectively in contact with and limited by a limit block.The structure of the present invention is reasonable,By simply switching the rotation direction of the vibration motor, the operator can quickly switch the vibrating screen machine to different working states, thereby improving the efficiency of the equipment and significantly reducing the labor intensity of the operator.
