Abstract

The invention discloses a recycled concrete aggregate screening device. According to the technical scheme, the recycled concrete aggregate screening device comprises a support frame and a machine body; the machine body includes a shell, and a screen body rotationally connected into the shell and slantly arranged; one end of the shell is connected with a feed hopper; screen holes are distributed in the screen body; the support frame is provided with a driving mechanism for driving the screen body to rotate; mounting bars are fixed in the shell; push rods corresponding to the screen holes are axially arranged; push balls with apertures larger than that of the screen holes are fixed at the end parts of the push rods; first springs for pushing the push rods to keep the push balls recessed in the screen holes are arranged between the push rods and the mounting bars; and when aggregates are blocked in one part of screen holes, the push balls are continuously recessed in all the screen holes in the rotating process of the screen body to push the aggregates blocked in the screen holes into the screen body, so that the cleaning of the aggregates blocked in the screen holes is more conveniently realized, and the screen body is kept in an excellent screening state.
