This application relates to the field of asphalt concrete production technology and discloses an asphalt concrete aggregate screening device, including an installation plate and equidistantly arranged installation blocks. The bottom surface of the installation plate is fixedly connected to equidistantly arranged installation rods, and each installation rod has a guide rod slidably connected to its inner wall. This asphalt concrete aggregate screening device, by setting rigid springs, rubber springs, and elastic buffer pads, uses rigid springs and rubber springs between the guide rods and installation rods, with installation blocks below forming an independent spring group. Square rods are connected by connector one, connector two, and bolts. Elastic buffer pads are placed at the connection points. The damping characteristics of the rubber springs absorb uneven vibrations, and the elastic buffer pads effectively absorb vibration differences between segments, improving the amplitude consistency of each part of the device. This solves the problem of uneven amplitude in traditional devices and improves the screening efficiency.
