The invention discloses a mining ore multistage vibration screen screening device and belongs to the field of ore screening. The mining ore multistage vibration screen screening device comprises a bottom plate. A mounting plate is arranged on the rear side of the upper surface of the bottom plate. The middle position of the interior of the mounting plate is provided with a through hole. A square frame is hinged to the outer surface of the mounting plate through first hinged shafts. The square frame is located on the surface of the front end of the mounting plate. A screening slot is formed inthe internal middle position of the square frame. The two sides of the outer surface of the square frame are both provided with fixing slots. A screening net is fixedly laid on the upper surface of the screening slot. The two ends of the screening net are both fixedly connected to the upper ends of the inner surfaces of the fixing slots. Pressing strips are fixedly connected to the inner surfacesof the fixing slots. The inner surfaces of the pressing strips are fixedly mounted on the inner surfaces of the fixing slots through fixing screws. In this way, the using convenience and stability ofthe mining ore multistage vibration screen screening device can be greatly improved, and the high screening efficiency is ensured.
