s5, throwing the large-particle sand on the second filter screen (18) to the third filter screen (19) under the action of centrifugal force, enabling the large-particle sand to fall into the second filter cavity (21), and enabling the small-particle sand to fall into the first discharge pipe (20) and be discharged through the second discharge pipe (23);
s6, filtering the sand falling into the second filtering cavity (21) through a fourth filtering net (24), and further screening out small-particle sand, and discharging the large-particle sand into the collecting cavity (5) through a discharging hole (25) under the action of centrifugal force;
s7, discharging large-particle sand, and discharging the sand falling into the second filtering cavity (21) into the discharging pipe (23) through the second discharging pipe (22) under the action of centrifugal force to discharge the sand;
s8, the second rotating shaft (28) rotates to transmit the rotation to the driven shaft (31) through the third driven gear (30), so that the rotating fan blades (34) rotate to generate wind power to cool the driving motor (15), and meanwhile, the influence on the normal work of the driving motor (15) caused by the sand entering the driving motor (15) is avoided.
