Description

Technical Field

[0001] The utility model relates to the technical field of material screening, in particular to a material screening device for building construction. Background Art

[0002] Sand is an important building material in construction. Most of the sand is salvaged from river sand or crushed from stones. It is inevitable that sand particles of different sizes will appear in the sand. In the process of construction, sand of different particle sizes has different uses, so it is necessary to screen the sand. In some large construction sites, large screening machinery and equipment are usually used. However, in some smaller sites, such as some self-built house construction sites in rural areas, due to various conditions, sand screening nets are often used for manual sand screening. The sand screening efficiency is low, the labor intensity is also high, and it is not easy to place stably. Although there are some small sand screening devices that realize the sand screening function by driving the horizontal screen to vibrate by a motor, there are still certain problems in use: the residues screened by the screen need to be manually cleaned, which increases the workload; when filling manually, the filling needs to be spaced according to the screening situation, and the personnel wait for a long time for filling, resulting in reduced efficiency; the movement and fixation are not convenient enough.

[0003] Therefore how to solve the above-mentioned technical problems just becomes the problem that the utility model faces. Utility Model Content
