Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a sand and gravel screening device for building construction. Background Art
[0002] Building construction refers to the production activities in the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations. It includes foundation engineering construction, main structure construction, roof engineering construction, decoration engineering construction, etc.
[0003] However, when the existing sand and gravel screening device for construction is used, the sand and gravel for construction are usually directly placed on the screen for screening. However, the position where the sand and gravel fall is fixed, and the sand and gravel fall on a local position on the screen, causing the sand and gravel to accumulate on the screen, and the sand and gravel cannot pass through the screen quickly, which has a certain impact on the screening efficiency of the sand and gravel. At the same time, the sand and gravel are in contact with the local position of the screen for a long time, and the local position of the screen will be bent and deformed, which has a certain impact on the service life of the screen. The screen is fixed in the frame by screws, and it is more complicated to clean the gravel remaining on the screen. Therefore, a sand and gravel screening device for construction is provided.
