[0027] Refer to Figure 4 , in an embodiment of the present utility model, the plugging and sealing assembly includes plugging grooves 21 opened on both inner walls of the screening tank 8. A sealing plate 20 is arranged inside the plugging grooves 21. By taking out the sealing plate 20 from inside the plugging grooves 21, the sand and gravel that do not pass through the screening can be conveniently discharged into the screening holes 19 on one side for screening, so as to facilitate the multi-layer screening process of sand and gravel.

[0028] Refer to Figure 4 and Figure 5 , in an embodiment of the present utility model, the discharging assembly includes a discharging cover 22 fixedly connected to the bottom of the screening hole 19. A discharging groove 23 is arranged at the center of the discharging cover 22. A discharge port 24 is arranged at the end of the discharging groove 23. The sand and gravel screened by the screening hole 19 fall into the discharging cover 22. The discharging groove 23 and the discharge port 24 arranged at the center of the discharging cover 22 are used to discharge the sand and gravel inside the discharging cover 22, so as to facilitate the collection process of the screened sand and gravel.

[0029] Working principle: The utility model works through the first driving member 11. The first driving member 11 drives the second rotating rod 12 to rotate, and the second rotating rod 12 drives the cam 13 to drive the screening groove 8 to swing reciprocally with the first rotating rod 6 as the center. During the reciprocating swing of the screening groove 8, through the operation of the second driving member 15, the second driving member 15 drives the one-way screw rod 16 to rotate, and the one-way screw rod 16 drives the moving frame 17 connected by threads to move. The moving frame 17 synchronously drives the feeding hopper 18 to move for feeding, so that it is convenient to evenly add sand and gravel to one end of the screening groove 8. Due to the inclined setting of the screening groove 8 and the reciprocating swing component driving the screening groove 8 to swing reciprocally, it is convenient to convey the sand and gravel to the screening holes 19 for screening. By sequentially taking out each sealing plate 20 from the insertion groove 21, the sand and gravel that do not pass through the screening are sequentially discharged onto the screening holes 19 with different apertures for sequential screening. The screened sand and gravel sequentially fall into the discharge grooves 23 at the centers of the respective discharge covers 22, and the screened sand and gravel are discharged through the discharge ports 24, so that it is convenient for construction projects to carry out construction processing.
