[0024] In summary, when the construction sand screening equipment is used, the equipment is placed in the construction site, and then the sand is shoveled into the sand screening chamber 3 through the iron shovel. At the same time, the output end of the third servo motor 24 drives the cam 25 to rotate. When the convex end of the cam 25 rotates toward the pressure block 26, the pressure block 26 pushes the connecting rod 27 to drive the sand screening box 2 to move downward. When the round end of the cam 25 rotates toward the pressure block 26, the return spring 28 pushes the pressure block 26 to move upward, so that the pressure block 26 drives the connecting rod 27 to move upward, and the connecting rod 27 drives the sand screening box 2 to move upward, so that the sand screening box 2 vibrates, so that the sand on the surface of the screen 8 falls into the guide hopper 19 through the sieve hole 9, and then is introduced into the guide hopper 19. The first servo motor 6 rotates the first guide wheel 7 and the second servo motor 18 rotates the second winding roller 16, so that the first guide wheel 7 reels the screen 8, and the second winding roller 16 releases the screen 8, so that the screen 8 moves toward the inside of the first winding groove 4, so that the screen 8 drives the larger coarse sand on the surface to move toward the inside of the first winding groove 4, so that the sand and gravel fall into the guide box 13, and then the larger coarse sand falls into the trolley 21 through the guide box 13. When a row of sieve holes 9 on the screen 8 moves to the bottom of the cleaning column 11, the first servo motor 6 and the second servo motor 6 rotate the first guide wheel 7 and the second servo motor 18 rotate the second winding roller 16, so that the first guide wheel 7 reels the screen 8, and the second winding roller 16 releases the screen 8, so that the screen 8 moves toward the inside of the first winding groove 4, so that the screen 8 drives the larger coarse sand on the surface to move toward the inside of the first winding groove 4, so that the sand and gravel fall into the guide box 13, and then the larger coarse sand falls into the trolley 21 through the guide box 13. The machine 18 stops working, and the telescopic end of the electric telescopic rod 10 pushes the movable plate 14 downward, so that the movable plate 14 pushes the cleaning column 11 to insert into a row of sieve holes 9, and pushes the sand blocked inside the sieve holes 9 to the outside of the sieve 8. Then the output end of the electric telescopic rod 10 drives the movable plate 14 and the cleaning column 11 to move upward, so that the cleaning column 11 moves out of the sieve holes 9, and then the first servo motor 6 and the second servo motor 18 continue to work. When the first winding roller 5 winds up the sieve 8 to a certain length, the output end of the second servo motor 18 drives the second winding roller 16 to reset and rotate, and the output end of the first servo motor 6 drives the first guide wheel 7 to reset and rotate, so that the second winding roller 16 rewinds the sieve 8. The first winding roller 5 releases the screen 8. At this time, the electric telescopic rod 10 inside the first winding groove 4 stops working, and the electric telescopic rod 10 inside the second winding groove 15 starts working. When the fine sand stored in the cart 21 reaches the required amount, the staff pushes the cart 21 to the place where the fine sand is needed, takes out the fine sand stored in the cart 21 for use, and then pushes the cart 21 back to the bottom of the material guide channel 20 to continue storing the screened fine sand. After the cart 21 is filled with coarse sand, the cart 21 is pushed to the waste dumping place, the coarse sand inside the cart 21 is taken out, and then the cart 21 is pushed back to the bottom of the material guide box 13 to continue collecting and storing the larger coarse sand that has been screened.
[0025] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
