[0002] During the building construction process, sand is needed as a building material. Before use, the sand needs to be screened by a sand screening device to separate the sand from gravel.

[0003] Most of the existing sand screening devices operate with a sand screening cylinder. The sand screening cylinder is inclined, and through the rotation of the sand screening cylinder, the fine sand falls through the sand screening cylinder, while the lumped coarse sand and stones fall to the bottom of the sand screening cylinder due to their own gravity and the inclination of the sand screening cylinder. During this process, the feeding port at one end of the sand screening cylinder is at a relatively high position, and workers need to use tools such as shovels for feeding, which is time-consuming and laborious, difficult to improve the feeding efficiency of the sand screening device, and thus affects the sand screening speed of the sand screening device, having certain inconveniences.

[0004] Therefore, it is necessary to provide a sand screening device for building construction to solve the above problems. Content of the Utility Model
