The particle size refers to the smallest diameter of a circle that can wrap the concrete block to be sorted.
In the construction waste, larger other materials such as wood, steel bars and the like are generally sorted out, and the remaining concrete blocks and bricks are crushed and screened, so that the particle size of the discharged waste is relatively fixed and is generally 2-6 cm.
In the invention, the relationship between the particle size of the material to be sorted and the angle of the nozzle and the spraying time of the nozzle can be obtained through a large number of experiments, so that the description is not repeated.
After the industrial personal computer judges the type and the size of the material to be sorted, the angle of the current air blowing seat 41 is adjusted according to the position information of the current air blowing seat 41 relative to the horizontal plane, and then the air pressure of the corresponding nozzle 43 is controlled according to the position coordinate of the corresponding collecting box 13, so that the material to be sorted can be blown into the corresponding collecting box 13.
