Problems solved by technology
[0002] In the construction industry, sand and gravel need to be screened to screen out large particles, branches, etc. in the sand and gravel before they can be used. Currently, when screening sand and gravel, workers need to use shovels to dump the sand and gravel into the screening device Screening of sand and gravel increases the workload of workers, and when sieving, only the large particles in the sand and gravel are simply screened out, and the screened gravel is not used, which wastes sand and gravel resources

The invention relates to the technical field of sand and gravel screening, in particular to a sand and gravel screening device and a screening method based on a layered structure type building. It includes a sand box, one side of the sand box is provided with a conveying device, the bottom of one side of the conveying device is provided with a screening box, and the inside of the screening box is respectively equipped with a screening device, a mobile grinding device, and a driving device for the screening device. The grinding device driving device sand box includes a sand box body and a sand box bottom box fixedly connected to the bottom of the sand box body, and the delivery device includes a delivery tube. The delivery tube is provided with a delivery cavity inside the delivery cavity. The rotating shaft is screwed and fixedly connected with a threaded feeding plate on the side wall of the conveying rotating shaft. The mobile grinding device includes a moving plate body. The bottom of the moving plate body and the upper surface of the fixed grinding plate are fixedly connected with a number of grinding balls interlaced with each other. Grinding column, the present invention mainly solves the problem that manual shoveling is used to screen sand and gravel, and the sand and gravel that are screened out are no longer used.
