[0028] See also Figure 1-4, a power mechanism is arranged on the outer wall of the screening bin 1, and the power mechanism comprises a motor 14, which is fixedly mounted on the outer wall of the screening bin 1, and a transmission wheel 12 is fixedly mounted on one end of each conveying shaft 7, and a transmission belt 13 is tensioned between the two transmission wheels 12, and the output end of the motor 14 is fixedly connected to one end of one of the conveying shafts 7, and the two conveying shafts 7 for rotating operation are connected through the transmission wheel 12 and the transmission belt 13, and the conveying shaft 7 is provided with power support by the motor 14. The sand screening machine for construction engineering filters the sand discharged into the screening bin 1 through the feed port 11 through the filter screen 2, and provides power to the conveying shaft 7 through the power mechanism, and then the conveying shaft 7 is synchronously driven to rotate while the conveying shaft 7 rotates, and the outer wall of the vibration plate 8 is continuously in contact with the bottom end of the filter screen 2, so that the filter screen 2 is in a continuous vibration state, thereby improving the filtering and screening efficiency of the filter screen 2 for sand, improving the sand screening efficiency of the device, and improving the practicality.
