[0038] Working principle:

[0039] like Figure 1-Figure 6As shown, when the above-mentioned sand screening device for construction is in use, the sand is first poured into the lower sand box 16 located above the sand screening platform 1, and falls to the top of the sand screening net 3 through the lower sand trough 20. The sand screening net 3 is used to filter sand particles, and larger particles remain on the net, while fine sand falls through the mesh to the inclined groove 19 below, which helps to guide the fine sand passing through the sand screening net 3 to flow out smoothly. One of the pulleys 7 is driven by the first motor 10, and is connected to the other pulley 7 through the transmission belt 8, thereby realizing the synchronous movement of the two reciprocating threaded rods 5, so that the scraper 6 can move back and forth on the sand screening net 3, helping to push the large particles of sand to move and prevent the mesh from being blocked.

The operator can adjust the speed and running time of the first motor 10 and the second motor 12 through the control panel 17 to achieve different screening efficiencies and processing capabilities. Removing residues on the sand screening net 3 can keep the sieve holes unobstructed and ensure that sand passes through the sand screening net 3 smoothly, thereby improving the screening efficiency and quality, and greatly improving the operation quality and use efficiency compared with traditional devices.
