Synchronous lifting type underwater screening machine

A lower support of the synchronous lifting type underwater screening machine is supported by supporting legs, and universal wheels are installed at the bottoms of the supporting legs. The motor, the synchronizer, the two commutators and the four lifters are fixed on the lower support, the motor is connected with the synchronizer, transmission shafts extend out of the two sides of the synchronizer and are connected with the two commutators respectively, and the four lifters are distributed at the four corners of a rectangle, are connected through the transmission shafts in pairs and are connected with the commutators on the sides through the transmission shafts. The lifting support is supported and fixed by the lifter, the screen body is fixed on the lifting support through the spring, the screen mesh is fixed on the lowest portion of the screen body, and the two vibration motors are fixed on the left side and the right side of the screen body. According to the technical scheme, the screen is stable in lifting
