The working principle of the sand screening device with the efficient screening function for municipal engineering construction provided by the utility model is as follows:

the first step is as follows: when the sand needs to be filtered, the sand is discharged into the screening box 1, the sand falls onto the connecting plate 4 under the action of the guide plate 2, and can be smashed and dispersed through the triangular blocks 6, and because the elastic spring 5 is arranged between the connecting plate 4 and the mounting plate 3, the elastic spring 5 is compressed under the action of gravity, and can restore to the original position when being contracted to a certain state, the connecting plate 4 can be bounced to bounce the sand on the connecting plate 4 so as to enable the sand to fall onto the first filter plate 16 for filtering, the qualified fine sand falls onto the second filter plate 19 through the first filter plate 16 and then falls onto the inner wall of the bottom of the screening box 1 from the second filter plate 19, so that not only the sand falling during screening can be dispersed, and the influence of the sand condensed into blocks on the efficiency of the screening work is avoided, the falling speed of the sand is slowed down, so that the sand cannot be accumulated on the first filter plate 16 and the second filter plate 19 at the same time, and the screening efficiency is improved;

the second step is as follows: when the screening speed needs to be increased to avoid blockage, the driving motor 11 is started to operate, the residual wheel 12 is driven to rotate through the output shaft of the driving motor 11, the teeth 10 can be driven to move through the residual wheel 12 under the meshing relationship, the movable rod 9 can drive the mounting block 13 to move upwards under the action of the supporting rod, the mounting block 13 drives the traction rope 14 and the first filter plate 16 to move upwards, the telescopic spring 17 is extended and contracted through the first filter plate 16, and when the residual wheel 12 is not connected with the teeth 10, the movable rod 9, the mounting block 13, the traction rope 14, the first filter plate 16 and the telescopic spring 17 can move downwards under the action of gravity and the telescopic spring 17 to reset, so that the first filter plate 16 vibrates when moving upwards and downwards, the screening speed can be increased, and the two vibration exciters 20 are started to operate simultaneously, the vibration exciter 20 vibrates to drive the second filter plate 19 to vibrate, so that the screening speed of sand is increased, the first filter plate 16 and the second filter plate 19 are prevented from being blocked by sand, and the first sealing piston and the second sealing piston are pulled to move, so that the first sealing piston and the second sealing piston can be separated from the first discharge hole and the second discharge hole, and unqualified sand can be discharged;

the third step: in the screening process, the exhaust fan 7 is started to operate, the dust excited by the dust hood is extracted, the filter screen has the function of filtering impurities, and the extracted dust is discharged into the air purifier 8 through the exhaust pipe to be purified and filtered, so that the pollution to the surrounding air can be avoided, and the health of people is influenced;

the fourth step: when discharging is needed, the third sealing piston is pulled by hand to move, so that the third sealing piston is separated from the third discharging hole, the cylinder 21 is started to operate, the material pushing plate 22 can be driven by the output shaft of the cylinder 21 to move, and the filtered sand is pushed by the material pushing plate 22 to be discharged from the third discharging hole.
