[0028] Working principle: When the utility model is in use, the first vibrator 8 and the second vibrator 12 are started by an external power supply, so that when the staff puts sand and gravel into the inner cavity of the screening box 1 through the feed pipe 4, the sand and gravel can be first buffered by the buffer plate 32, and the sand and gravel can be slowly scattered into the inner cavity of the first opening slot 6, and the sand and gravel can be preliminarily screened by the coarse screen 7, and the screened sand and gravel can be dropped into the inner cavity of the second opening slot 10, so that the sand and gravel can be screened for the second time by the fine screen 11, and the qualified quartz sand can be discharged into the bottom of the inner cavity of the screening box 1. When discharging, the staff puts the collection bag on the annular plate 23, and pushes the pressing plate 25 downward by starting the electric telescopic rod 24, so that the collection bag can be pressed and fixed, thereby automatically bagging the quartz sand. As the weight increases, when the set bagging amount is reached, the pressure sensor 28 transmits a signal to the controller 29, and the controller 29 activates the alarm 30 to sound an alarm, thereby reminding the staff to remove and replace the bagged collection bag in time.

The rotation of the threaded rod 17 drives the two threaded sleeves 19 to move upward, and drives the cross bar 20 to move upward. The upward movement of the cross bar 20 drives the first pressure bar 21 and the second pressure bar 22 on the same side to move upward and away from the screen, so as to facilitate the staff to remove and replace the existing screen. When the new screen is placed into the inner cavity of the screening box 1, the hand-cranked wheel 18 can be rotated in the opposite direction to drive the first pressure bar 21 and the second pressure bar 22 to press the screen.
