[0024] Working principle: When in use, the utility model puts the waste concrete to be separated into the separation box 12 through the feed chute 7. When the waste concrete to be separated is put into the separation box 12, the reduction motor 3 is turned on by control. When the reduction motor 3 is turned on, the crushing shaft 4 is driven to rotate. When the crushing shaft 4 rotates, the crushing blade 5 is driven to rotate. When the crushing blade 5 rotates, it cooperates with the crushing teeth 6 to crush the waste concrete. When the waste concrete is crushed, the crushed waste concrete will be discharged into the separation box 12 through the discharge chute 8. When the crushed waste concrete is discharged into the separation box 12, the crushed waste concrete will be blocked and filtered by the filter plate 16. When the filter plate 16 blocks and filters the crushed waste concrete, By controlling to start the vibration motor 15, when the vibration motor 15 is turned on, it will drive the separation box 12 to vibrate.

When the separation box 12 maintains continuous vibration, the waste concrete crushed at the upper end of the filter plate 16 will be continuously vibrated downward by the force of the continuous vibration of the separation box 12. When the crushed waste concrete is continuously vibrated downward, the crushed waste concrete will fall into the separation box 12 through the filter holes, and the aggregate in the waste concrete will be discharged outward along the guide groove 17 through the upper end of the filter plate 16, thereby realizing the effect of facilitating the separation of the waste concrete.
