[0001] The utility model relates to a sand screening device, in particular to a sand screening device for building construction, which belongs to the technical field of building construction devices. Background Art
[0002] If the sand used in the construction process contains a lot of impurities and stones, it will bring great risks to the use of the building, causing cracks, deformation and other problems. Therefore, before the sand is used, it is necessary to remove the impurities and stones in the sand through sand screening equipment to improve the purity and quality of the sand and ensure the service life and safety of the building. The sand screening equipment is generally equipped with an inclined screen. During the reciprocating motion of the screen, the sand to be screened is added to one end of the screen, and then the sand will flow toward the other end of the screen under the action of gravity. In this process, the sand screening work is realized.
[0003] However, the length of the screen on the traditional sand screening equipment is limited, and the sand flows on the screen for a short time, so the screen may not be clean. In addition, the screen is mostly fixed by multiple bolts. Therefore, when the screen needs to be replaced, it takes a certain amount of time to twist the bolts to install and disassemble the screen, which is not convenient for the inspection and maintenance of the screen.

[0026] As a technical optimization solution of the utility model, Figure 1 and Figure 4 As shown, a driving structure 5 is provided on the support frame 1 , and a guide hopper 10 is fixedly connected to the support frame 1 , so that the guide hopper 10 can play a role of backflow on sand.
[0027] As a technical optimization solution of the utility model, Figure 2 and Figure 4 As shown, the driving structure 5 includes a support plate 501 and a motor 502. The support frame 1 is fixedly connected to the support plate 501, and the motor 502 is installed on the support plate 501. A turntable 503 is fixedly connected to the output shaft of the motor 502, and a guide sleeve 504 is rotatably connected to the turntable 503. One end of the support plate 3 is fixedly connected to a connecting plate 506, and a long groove 505 is provided on the connecting plate 506.
