S4, sand in the material blocking shell (71) rotates through motor drive intermeshing' S in a driving box (80) two flood dragon puddler (81) and carries the grit stirring, act through rotating motor (79) simultaneously, make it make pivot (76) rotate under the transmission of bevel gear group, and then make vibration cam (78) rotate and hit the lower surface of beating material blocking shell (71), and make material blocking shell (71) vibrate under the effect of damping spring (72), thereby make the grit in material blocking shell (71) shake the separation, and make the fine sand of screening drop to the upper surface of screen cloth conveyer belt (2) through screening hole (82), and the gravel piece that screens out is carried to blanking pipe (75) through flood dragon puddler (81) and is discharged and collect, spray shower nozzle (77) spray the grit when flood dragon puddler (81) stirs, the screen cloth on material blocking shell (71) and conveyer belt (2) is passed to in bottom groove (1), and from drain groove (11) to carry out the filter cloth that can pass screen cloth conveyer belt (2) and discharge and collect, thereby screen cloth conveyer belt (21) is passed through the guide plate front of the filter cloth conveyer belt (21.
