[0010] This utility model provides a labor-saving sand screening machine for construction operations, which has the following beneficial effects:
[0011] 1. This labor-saving sand screening machine for construction operations, equipped with a conveying pipe, a first electric telescopic rod, and a discharge channel, allows workers to simply push sand into the conveying pipe through the inlet. At this point, a pump extracts liquid from the tank and discharges it into a liquid bladder through the other end of the pump. This expansion of the bladder pushes the push plate upwards, causing it to push the sand from the conveying pipe to one side of the push block. Then, the telescopic end of the first electric telescopic rod pushes the push block, which in turn pushes the sand from the conveying pipe through the discharge channel onto the top of the screen plate for screening. This eliminates the need for workers to shovel the sand and lift it onto the screen, significantly reducing their workload.
[0012] 2. This labor-saving construction sand screening machine is equipped with a frame, a first spring and a screen plate. The screen plate vibrates through a vibrating motor, which in turn vibrates the screen mesh to separate sand and stones. The stones are discharged through the screen plate, and the sand screened through the screen mesh falls onto the surface of the guide plate and is discharged through the guide plate, thus separating the stones from the sand.

[0022] A discharge channel 14 is fixedly connected to the other side of the conveying pipe 13. One end of the discharge channel 14 extends into the inside of the conveying pipe 13. The outer side of the push block 16 matches the inner cavity of the discharge channel 14. The push block 16 can be inserted into the discharge channel 14 to push the sand inside the conveying pipe 13 to the top of the screen plate 7 through the discharge channel 14, and then screened by the screen mesh 12 on the screen plate 7.
[0023] Tension springs 18 are fixedly connected to the bottom of the inner cavity of the conveying pipe 13 and to both sides of the liquid bladder 17. The top of each tension spring 18 is fixedly connected to the bottom of the push plate 19. The push plate 19 can be pulled back to its initial position by the tension springs 18.
[0024] A liquid tank 20 is fixedly connected to one side of the fixed platform 1, and a pump 21 is fixedly connected to one side of the liquid tank 20. One end of the pump 21 extends into the liquid tank 20, and the other end of the pump 21 extends into the liquid bladder 17. The pump 21 can transport or output the liquid inside the liquid bladder 17.
[0025] A feed inlet 25 is provided on one side of the conveying pipe 13. One end of the feed inlet 25 extends into the inside of the conveying pipe 13, and sand is pushed into the inside of the conveying pipe 13 through the feed inlet 25.
[0026] A pusher slope 22 is fixedly connected to one side of the fixed platform 1. Two fixed frames 9 are fixedly connected to the bottom of the screen plate 7.

[0027] In summary, this labor-saving sand screening machine for construction operations involves pushing a trolley up the fixed platform 1 via the pushing ramp 22, then tilting the trolley onto the top of the platform 1. Workers then simply push sand into the conveying pipe 13 through the inlet 25. At this time, the pump 21 extracts liquid from the liquid tank 20 and discharges it into the liquid bladder 17 through the other end of the pump 21. This causes the liquid bladder 17 to expand, pushing the push plate 19 upwards. The push plate 19 then pushes the sand inside the conveying pipe 13 to one side of the push block 16. The telescopic end of the first electric telescopic rod 15 then pushes the push block 16 to move, causing the push block 16 to move the sand in the conveying pipe... The sand inside channel 13 is pushed onto the top of screen plate 7 through discharge channel 14. Vibration motor 10 causes screen plate 7 to vibrate, which in turn causes screen 12 to vibrate and separate the sand from the stones. The stones are discharged through screen plate 7, and the sand separated by screen 12 falls onto the surface of guide plate 3 and is discharged through guide plate 3. Then, the extension end of the first electric telescopic rod 15 drives push block 16 to reset and move. Then, pump 21 draws out the liquid inside liquid bladder 17 and discharges the liquid into liquid tank 20 through the other end of pump 21, causing liquid bladder 17 to contract. At this time, tension spring 18 drives push plate 19 to move down and continue feeding.

When it is necessary to fill the feed inlet 25, the baffle 27 is moved upward by the telescopic end of the second electric telescopic rod 26 to open the feed inlet 25. When it is necessary to convey sand inside the conveying pipe 13, the baffle 27 is pushed downward by the telescopic end of the second electric telescopic rod 26 to close the feed inlet 25.
