The device can fully screen sand needing to be screened, and is high in screening efficiency.

Description

[0001] This application is a divisional application of an invention patent application with application number: 2015107605141, invention name: a sand screening device for building construction, and application date: November 10, 2015. technical field [0002] The invention relates to the technical field of construction machinery, in particular to a sand screening device for construction. Background technique [0003] At present, the construction sand sold on the market contains a lot of impurities such as mud and soft stones, which must be screened before use. When the yellow sand is fished from the bottom of the river, it contains more water. If it hits the rainy season again, the old-fashioned The bracket sieve, the mesh of the sieve is easy to block, and only three or five shovels are sprinkled to sieve out a shovel of fine sand, and the quantity cannot meet the use demand. [0004] Therefore, it is necessary to provide a new technical solution to solve the above technica...

[0003] At present, the construction sand sold on the market contains a lot of impurities such as mud and soft stones, which must be screened before it can be used. When the yellow sand is fished out from the bottom of the river, it contains more water. If it hits the rainy season again, the old-fashioned Bracket sieve, the mesh of the sieve is easy to clog, sprinkle with three or five shovels to sieve out a shovel of fine sand, the quantity cannot meet the use demand
