Composite vibrating screen

The utility model relates to the technical field of mining machinery, in particular to a combined type vibrating screen for separating ore from ore powder. The feeding assembly is used for feeding raw materials and can be opened and closed through the gravity of the ore raw materials, the screening assembly is used for screening the ores with different particle sizes, and the conveying assembly is used for conveying the ores with the qualified particle sizes and powder. Due to the fact that the feeding assembly capable of being opened and closed through the gravity of ore raw materials is designed on the vibrating screen, ore can be prevented from directly falling on the upper portion of the vibrating screen, the buffering effect is achieved when the ore falls down, and the problem that in the prior art, the ore directly falls on the upper portion of the vibrating screen, large impact force is generated on the vibrating screen is solved. And a buffering component between the ore and the vibrating screen is la
