[0020] Please see Figures 1-4This utility model provides a technical solution: a sand screening device for construction, including a telescopic rod 1, a rotating shaft 2, and a frame 3. The telescopic rod 1 is rotatably connected to the frame 3 via the rotating shaft 2. The frame 3 is a cuboid frame with openings at both the top and bottom. Three slots 5 are evenly distributed on the inner wall of the frame 3. There are four telescopic rods 1 and four rotating shafts 2, which are respectively set at the four corners of the bottom surface of the frame 3. A base is set at the bottom of the telescopic rod 1 to achieve stable support for the frame 3 and to allow for height and angle adjustment to adapt to different construction site requirements. A vibration motor 4 is installed on one side of the frame 3. Three slots 5 are opened through the inside of the frame 3 for inserting screens 6 of different specifications. Screens 6 are inserted into the slots 5, and the outer wall of the screens 6 abuts against the screen.
