[0002] A sand screening machine is a mechanical equipment specially used to separate different particle sizes in sand. It is usually composed of a frame, a sieve, a transmission device and a vibration device. The sieve is the core component, which is composed of sieves with different mesh sizes. Under the action of vibration or rotation, the sand screening machine separates the sand through the sieve to meet different work requirements. It has a simple structure, is economical and easy to operate, and is widely used in rivers, reservoirs, coal yards and other scenes to achieve efficient separation and processing of sand and gravel.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 A sand screening machine for construction engineering comprises a sand screening machine body 1, a rectangular mounting frame 2 is movably connected to the inner surface of the upper end of the sand screening machine body 1, a rectangular screen 3 is fixedly connected to the outer surface of the lower end of the rectangular mounting frame 2, a material discharge plate 4 is fixedly connected to the inner surface of the front end of the sand screening machine body 1, a driving motor 8 is fixedly connected to the outer surface of the left side of the sand screening machine body 1, a rotating shaft 11 is fixedly connected to the driving end of the driving motor 8, a cam 12 is fixedly connected to the outer surface of the right side of the rotating shaft 11, an outer wall of the cam 12 contacts with the outer surface of the lower end of the rectangular mounting frame 2, a circular mounting hole is opened on the outer surface of the upper end of the rectangular mounting frame 2, and a fixing screw 10 is threadedly connected to the inner wall of the circular mounting hole;

[0024] When the sand screening machine body 1 is started, the driving motor 8 starts to work and drives the rotating shaft 11 to rotate through the driving end. The rotation of the rotating shaft 11 further causes the cam member 12 to perform circular motion. Since the outer wall of the cam member 12 is in contact with the outer surface of the lower end of the rectangular mounting frame 2, when the cam member 12 rotates, its raised portion will push the rectangular mounting frame 2 and the rectangular screen 3 below it to vibrate back and forth, and this vibration causes the sand and gravel placed on the rectangular screen 3 to be screened. Due to the action of gravity, large particles of sand will slide down along the surface of the screen, while small particles of sand will fall below the screen through the mesh of the screen. As the sand screening machine body 1 continues to work, large particles of sand are continuously screened to one side of the screen, while small particles of sand fall into the interior of the sand screening machine body 1 through the screen. At the same time, the large particles of sand after screening slide down to the designated collection area along the inclined surface of the unloading plate 4 under the action of gravity. The design of the blanking plate 4 ensures that the sand can slide down smoothly and orderly, avoiding the accumulation and blockage of sand. In addition, the threaded connection between the circular mounting hole at the upper end of the rectangular mounting frame 2 and the fixing screw 10 provides reliable support for the fixing of the rectangular mounting frame 2, and also facilitates the replacement and maintenance of the rectangular screen 3. By adjusting the tightness of the fixing screw 10, the rectangular mounting frame 2 and the rectangular screen 3 can be stably installed or conveniently disassembled.

[0025] The left outer surface of the sand screening machine body 1 is movably connected with a storage trolley 5, the left outer surface of the storage trolley 5 is fixedly connected with a push-pull handle 6, the lower end outer surface of the storage trolley 5 is rotatably connected with a bottom roller 7, the right inner surface of the sand screening machine body 1 is fixedly connected with a first magnet block 9, the right outer surface of the storage trolley 5 is fixedly connected with a second magnet block, the second magnet block is magnetically connected to the first magnet block 9, the right outer surface of the storage trolley 5 is provided with a rectangular mounting groove adapted to the second magnet block, and the storage trolley 5 is fixedly connected to the second magnet block through the rectangular mounting groove;

[0026] When the sand screening machine body 1 is working, in addition to screening sand and gravel, it also involves the coordinated use of the storage cart 5. The storage cart 5 is movably connected to the left outer surface of the sand screening machine body 1 through the roller 7 at the bottom thereof, so that the storage cart 5 can be easily approached or away from the sand screening machine body 1. When the sand screening machine body 1 performs screening work, the screened small particles of sand fall into the inside of the sand screening machine body 1 through the rectangular screen 3, and then fall into the storage cart 5. The setting of the storage cart 5 allows the screened sand to be automatically collected, avoiding the tedious and time-consuming manual collection.

[0027] The material storage vehicle 5 is located directly below the rectangular screen 3 , the material discharge plate 4 is located obliquely below the rectangular mounting frame 2 , and the rear end of the material discharge plate 4 extends to the lower end of the rectangular screen 3 .
