Sand screening device for building construction

Abstract

The invention discloses a sand screening device for building construction. The sand screening device for building construction comprises a box body (1), wherein a feeding port (2) is formed in the top of the box body (1); a transmission cavity (3) and a sand screening cavity (4) are formed in the box body (1); a screen (5) which corresponds to the feeding port (2) in position and is obliquely arranged is arranged in the sand screening cavity (4); a stirring mechanism (6) is arranged below the screen (5); a bottom discharging port (7) is formed in the side face, below the stirring mechanism (6), of the box body (1); the screen (5) is transversely connected with the sand screening cavity (4) in a sliding mode; and a middle discharging port (8) communicated with the outside is formed in the lower end of the screen (5). The sand screening device for building construction provided by the invention can screen sand at a variable speed, is good in sand screening effect, and has the characteristics of high practicability and good reliability.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a sand screening device for building construction. Background technique [0002] In the process of building construction, it is necessary to mix sand and cement to form cement mortar and then use it for wall masonry. However, ordinary sand contains more impurities and has different particle sizes. It is necessary to manually use a sieve to screen the sand to obtain the particle size. The finer sand is widely used in re-construction sites, and the artificial use of screens to screen sand is inefficient and requires a lot of labor, which is difficult to meet the needs of use, and the existing vibrating sand screening machines on the market The time range is small and consistent, and the sand cannot be moved greatly, so it is difficult to ensure the sand screening effect, resulting in more waste of raw materials, poor practicability and reliability.
