Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, in particular to a sand screening machine for construction. Background Art

[0002] Construction refers to production activities during the implementation phase of engineering construction, and is the construction process of various types of buildings. The place where construction work takes place is called a "construction site" or "construction site", and yellow sand is one of the commonly used materials in construction. It is mixed with other materials to form concrete or cement for use. The coarseness of sand refers to the average coarseness of sand particles of different particle sizes mixed together, and the particle grading of sand refers to the matching ratio of sand particle size. Well-graded sand can not only save cement, but also improve the density and strength of concrete and mortar, so sand screening machines are used.

[0003] Yellow sand needs to be screened when used in construction. Currently, it is mostly screened manually, which is not only time-consuming and labor-intensive, but also has low screening efficiency. In addition, the diameter of yellow sand required for different construction needs is also different, so different screens are needed for screening. However, the existing sand screening machines are not convenient for disassembly and replacement of the screens, which makes the screening efficiency of sand low. Therefore, we propose a construction sand screening machine to solve the above problems. Utility Model Content
