A transmission component 11 is installed in cooperation between the partition plate 13 and the sieve plate 1. A filtering component 6 for screening sand is installed on the top of the transmission component 11 through the quick-release component 7. A control panel 3 is arranged on the outer wall of the sieve plate 1;

[0035] Among them, the control panel 3 is wirelessly connected to a motor 1101 for controlling the start of the motor 1101;

[0036] The transmission component 11 includes a motor 1101 and a turnover plate 1105, and the quick-release component 7 includes a fixed shaft 701 and a mounting block 706;

[0037] Above and below the side wall of the fixed shaft 701, limiting plates 702 are symmetrically installed respectively. On the side of the four limiting plates 702 away from the fixed shaft 701, sliding grooves 705 are respectively opened.

A connecting shaft 1104 is provided in the middle of the partition plate 13. The connecting shaft 1104 penetrates through the partition plate 13 and extends below the partition plate 13. The power output shaft of the motor 1101 is installed with the connecting shaft 1104. A first scraping plate 1102 is installed on the outer wall of the connecting shaft 1104 above the partition plate 13. Sealing plates 1103 are symmetrically arranged at the bottom of the first scraping plate 1102;

[0048] A turnover plate 1105 is arranged at the top of the connecting shaft 1104. A discharge port 14 is opened at the top of the partition plate 13. A discharge pipe 12 is arranged in the inner cavity of the discharge port 14. The discharge pipe 12 extends downward and penetrates through the bottom of the sieve plate 1;

[0054] Among them, during use, the clamping frame 502 is clamped in the limiting groove 9. When the filtering component 6 rotates, the second scraping plate 501 on the clamping frame 502 will scrape the sieve plate 603.

[0055] When a sand screening device for green building projects is in operation, first, the electrical equipment of the device is powered on. During use, the motor 1101 is started through the control panel 3.

After removal, the fixed shaft 701 is rotated, and the limiting plate 702 is slid out of the inner cavity of the insertion groove 707. At this time, the limit on the filtering assembly 6 in the vertical direction is released;

[0058] Finally, hold the connecting plate 602 and slide the mounting block 706 out of the positioning groove 10;

[0059] During installation, the positioning groove 10 on the connecting plate 602 is aligned with the mounting block 706 at the top of the turnover plate 1105 for insertion. After insertion, the limit block 7011 is toggled to drive the rotating ring 7010 and another limit block 7011 to rotate, and the limit block 7011 clamped in the second through groove 7013 is rotated and removed. At this time, the clamping block 703 is inserted, and the clamping block 703 is inserted into the clamping block 703, the first through groove 708 and the clamping block 703 in order from high to low. At this time, the limit block 7011 is released, and under the action of the torsion spring 7014, the two limit blocks 7011 and the rotating ring 7010 will be reset, and one limit block 7011 will be clamped into the clamping groove 704 and the second through groove 7013 at the same time, realizing the advantage of quickly disassembling and installing between the filtering assembly 6 and the turnover plate 1105.
