[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0018] like Figure 1 、 Figure 2 and Figure 3As shown, the utility model proposes a sand and gravel grading and screening device for dry-mixed mortar production, including a base 1, a support frame 2, a fixed structure 3 and a rotating filter structure 4. The support frame 2 is arranged on the base 1, the fixed structure 3 is arranged on the support frame 2, and the rotating filter structure 4 is arranged on the fixed structure 3. The fixed structure 3 includes a filter shell 5, a support plate 6, a discharge guide plate 7, a fixed seat 8, a feeding hopper 9 and a connecting pipe 10. The filter shell 5 is fixedly arranged on the support frame 2, and the support plate 6 is fixedly sealed on both sides of the filter shell 5. The discharge guide plate 7 is fixedly arranged below the filter shell 5, and the discharge guide plate 7 is arranged to be inwardly inclined and closed. The fixed seat 8 is fixedly arranged on the filter shell 5, the feeding hopper 9 is fixedly arranged on the fixed seat 8, and the connecting pipe 10 is connected to the feeding hopper 9. The rotating filter structure 4 includes Bearing 11, bearing 2 12, screen 13, waste outlet 14, gear 15, fixed seat 2 16, motor 17 and gear 2 18. Bearing 11 is embedded in the upper support plate 6, bearing 2 12 is embedded in the lower support plate 6, one end of the screen 13 is embedded in the bearing 11 and the other end is embedded in the bearing 2 12. The screen 13 is arranged in a serpentine shape and is inclined at forty-five degrees. The waste outlet 14 is fixedly connected to the bottom end of the screen 13. Gear 15 is fixedly wrapped on the screen 13. Fixed seat 2 16 is fixed on the filter housing 5. Motor 17 is fixed on fixed seat 2 16. Gear 2 18 is driven by the motor 17 and meshes with gear 15. The front end of the screen 13 is rotatably connected to the connecting pipe 10.

[0019] The screen 13 is rotated by the motor 17 and the gear 18 is driven by the gear 15 to rotate, thereby the gear 15 drives the screen 13 to rotate on the bearing 11 and the bearing 2 12. At this time, the front end of the screen 13 rotates in the connecting pipe 10, and then the sand and gravel that need to be screened are connected to the feeding hopper 9 through the discharge pipe. At this time, the sand and gravel flow into the feeding hopper 9 in a quantitative manner, and then flow into the screen 13 from the connecting pipe 10 on the feeding hopper 9. At this time, the screen 13 rotates, and the serpentine belly shakes up and down to fully filter the sand and gravel. At the same time, the screen 13 tilts downward and flows quickly. The fine sand and gravel after screening fall into the filter housing 5 and are discharged through the discharge guide plate 7 for collection at the bottom for standby use. At the same time, the remaining residue after screening is discharged and collected through the waste outlet 14. The above is the use process of the sand and gravel grading screening device for dry mixed mortar production.
