Sand screening device for municipal construction
By introducing a dividing frame and support structure into the sand screening device, combined with an inclined guide chute and a guide frame, the problem of poor sand screening effect caused by the excessively fast dumping speed of the bulldozer was solved, and more efficient sand and gravel separation was achieved.

AI Technical Summary
In existing sand screening devices, the material separation is incomplete and the screening effect is poor because the bulldozer dumps the material too quickly and the screen is tilted too much.
A sand screening device including a dividing frame and support rods was designed. The dividing frame and support rods divide large stones, and combined with the inclined guide chute and stone guide frame, the material is screened in layers to improve the screening accuracy.
It effectively slows down the dumping speed of bulldozers, separates large stones, improves sand screening accuracy, reduces material spillage and waste, and improves screening effect.
