[0029] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0030] Please refer to Figures 1-5 The utility model provides a technical scheme: a sand screening device for construction site, which comprises:

[0031] a base 1, the bottom of which is provided with a plurality of casters 2;

[0032] a fixed frame 3, which is fixedly connected to the base 1;

[0033] a screen frame 4, which is installed on the fixed frame 3, and the screen frame 4 is formed by a plurality of round rods 5;

[0034] a top plate 6, which is slidingly connected in the screen frame 4, and the top of the top plate 6 is provided with a guide pyramid 7;
