Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Example 1: During the sand screening process of the existing sand screening machine, the sieve holes of the sand screening mesh are easily blocked by small stones in the sand. Therefore, manual processing needs to be carried out regularly, otherwise the sand screening efficiency will be affected. To solve this technical problem, as Figure 1 , Figure 2 , Figure 3 and Figure 5 shown:

[0032] A sand screening machine for construction engineering with an anti-blocking structure, including the device body 1. A feed inlet 2 is installed at the upper left end of the device body 1, and a servo motor 3 is fixedly installed at the rear side of the feed inlet 2. The output end of the servo motor 3 is fixedly connected to a left gear 7, and the end of the left gear 7 far from the servo motor 3 is fixedly connected to a left crushing roller 8, and the end of the left crushing roller 8 is rotationally connected to the feed inlet 2; a right crushing roller 10 is rotationally connected to the right side inside the feed inlet 2, and a right gear 9 is fixedly connected to the rear side of the right crushing roller 10; the left gear 7 is meshed with the right gear 9, and the left crushing roller 8 and the right crushing roller 10 are rotationally connected to the feed inlet 2; a vibration plate 11 is fixedly installed inside the device body 1, and a sieve mesh 13 is fixedly installed at the bottom end inside the vibration plate 11. A vibration motor 12 is fixedly installed on the rear wall inside the device body 1, and the output end of the vibration motor 12 is fixedly connected to the vibration plate 11.

[0033] First, the user places the device at the position where it needs to work. The user starts the servo motor 3, and the servo motor 3 rotates to drive the left gear 7 to rotate, thereby causing the right gear 9 to rotate, and the left crushing roller 8 and the right crushing roller 10 will also rotate. The user starts the vibration motor 12, thereby causing the vibration plate 11 to vibrate, and the sieve mesh 13 will also vibrate. Then, the prepared sand is poured into the feed inlet 2. The large-particle stones in the sand will be broken by the left crushing roller 8 and the right crushing roller 10 and fall onto the sieve mesh 13. The sand falls from the sieve holes on the sieve mesh 13 to the bottom conveyor table 14. By crushing the stones inside the sand with the left crushing roller 8 and the right crushing roller 10, the stones are prevented from blocking the holes in the sieve mesh 13, thereby achieving the anti-blocking effect.

[0034] Example 2: The technical content disclosed in this example is a further improvement based on the above Example 1. During the process of pouring sand into the material inlet of the existing sand screening machine, it is necessary to control the feeding amount. If the feeding amount is too large, the sand may block the material inlet. Therefore, manual blockage removal is required, which is time-consuming and laborious.

[0036] A dredging structure is provided. During the operation of the device, the rotation of the servo motor 3 will also drive the rotation of the belt 4, thereby causing the rotation of the rotating shaft 5. The rotation of the rotating shaft 5 drives the rotation of the rotating plate 6, and the rotation of the rotating plate 6 pushes the sand to prevent too much sand from entering and blocking at the feed inlet 2, thus achieving the anti-blocking effect.

[0037] Embodiment 3: The technical content disclosed in this embodiment is a further improvement based on the above-mentioned Embodiment 1 and Embodiment 2.

[0039] A drying structure is provided. The user starts the variable-speed motor 17, and the rotation of the variable-speed motor 17 drives the rotation of the rotating rod 18, thereby causing the rotation of the drying cylinder 15. The electric heating resistance wires 16 in the drying cylinder 15 are energized and heated up, so that the surface temperature of the drying cylinder 15 becomes higher. During the sand screening process of the device, the sand falls into the drying cylinder 15 through the conveyor belt in the conveyor table 14, and the drying cylinder 15 heats the sand to dry the moisture in the sand and make it dry, thus achieving the drying effect.
