This arrangement makes the connection more stable.

Further, the bottom of the discharging hole is hinged with a switch door. The material outlet can be opened for discharging after sieving.

Further, the discharge ports are all connected with a material collecting box. The collection box is convenient for collecting the screened ore materials.

Further, a double-shaft motor is arranged on the positioning plate, and two output shafts of the double-shaft motor are connected with eccentric blocks. When the screen plates vibrate, only the double-shaft motor is required to be started, and the double-shaft motor drives the eccentric blocks to rotate, so that the positioning plate drives the screen plates to vibrate simultaneously.
