After the vibrating screen is finished, the telescopic rods of the multi-stage lifting telescopic rods 13 are driven to extend out by the telescopic rod driving mechanism 19, so that the lifting sleeve screens 7 of all the stages arranged on the telescopic rods correspondingly rise (as shown in fig. 4 and 5), and the telescopic rods enter a layered state to be discharged. When the aggregate with a certain particle size or a certain range of particle sizes needs to be selected for automatic discharging, the lifting sleeve sieve 7 of the layer with the corresponding pore size or the cylinder lifting mechanism 36 of the fixed sleeve sieve 6 is started to drive the sleeve sieve cylinder 29 to ascend, so that the sleeve sieve cylinder 29 and the conical sieve surface 30 are separated from each other, and the aggregate with the corresponding required particle size reserved on the upper side of the conical sieve surface 30 is discharged into the annular aggregate groove 33 (as shown in fig. 13). After discharging is finished, the cylinder lifting mechanism 36 drives the sleeve screen cylinder 29 to fall back to the initial position closed with the conical screen surface 30, and the annular groove discharging door 34 is opened; then, the material brush rotary gear 42 is driven to rotate by the material brush rotary motor 41, so that the material brush rotary motor 41 and the telescopic connecting column 40 and the material collecting brush 38 at the lower part thereof move circularly at a constant speed in the annular material collecting groove 33 around the outer edge teeth 43 of the sleeve screen cylinder 29 and the material brush rotary rail 44 on the outer side wall of the sleeve screen cylinder, further the aggregate with specific particle size in the material collecting groove is pushed to the annular groove discharging door 34, and then the aggregate is discharged to the spiral discharging slideway 3 through the slideway material guide hopper 35 connected with the annular groove discharging door 34 and is discharged from the discharging port 10 connected with the discharging inlet 16 at the tail end of the slideway.
