[0002] Sand plays an important role in the construction process of construction projects, mainly in: improving the strength of concrete, controlling the shrinkage of concrete, enhancing the plasticity and frost resistance of concrete, etc. Concrete sand is not only used to make concrete structures, but also can be used to make cement, lay bricks, etc. It has a direct impact on the quality and safety of buildings.

[0003] Before using construction sand, it needs to be screened to remove large particles in the sand to prevent them from being mixed with the sand and affecting the quality of the building. The existing screening method is to make the sand and large particles pass through the screening plate for screening. However, some sand contains moisture, which will cause the sand to clump. The agglomerated sand cannot pass through the screening plate, but is discharged together with other large particles, resulting in waste of raw materials.

[0004] Therefore, we have made improvements to this and proposed a sand screening equipment for construction projects. Utility Model Content

[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0022] Example: Figures 1 to 5 As shown, the utility model is a sand screening device for construction projects, including a frame 2, the top surface of the frame 2 is through, and a feed port 3 is fixedly installed on one side of the frame 2. The sand to be screened can be poured into the frame 2 through the feed port 3 for screening. The two sides of the feed port 3 are sealed and fixedly connected to the side walls of the frame 2, and are located on the top of the linear guide rail 10 to prevent it from affecting the movement of the slider 11.

[0023] The two ends of the frame 2 are symmetrically fixedly connected with support feet 1, which can support the frame 2, and the bottom end of the frame 2 is connected to a discharge port 4. A screening plate 9 is detachably installed inside the frame 2, and the sand screened by the screening plate 9 can be discharged to the outside of the frame 2 through the discharge port 4.

[0024] Linear guide rails 10 are symmetrically installed on both sides of the interior of the frame 2, and a connecting plate 12 is installed between the two linear guide rails 10. The bottom ends of the connecting plates 12 are respectively provided with pressure rollers 19 and stirring rods 14, and the pressure rollers 19 and stirring rods 14 are respectively in contact with the top surfaces of the screening plates 9; the pressure rollers 19 can be used to crush the screened sand, thereby breaking up the agglomerated sand, and the stirring rods 14 can be used to move the sand to facilitate its passage through the screening plates 9.

[0025] The frame 2 has mounting grooves symmetrically formed on both sides thereof, into which linear guide rails 10 are fixedly mounted. Slide blocks 11 are slidably mounted on the linear guide rails 10, and a connecting plate 12 is fixedly mounted between the two slide blocks 11. The slide blocks 11 slide on the linear guide rails 10, thereby driving the connecting plate 12 to move, thereby driving the stirring rod 14 and the pressure roller 19 at the bottom of the connecting plate 12 to move.

[0026] A mounting plate 13 is obliquely mounted on one side of the connecting plate 12, and stirring rods 14 are evenly distributed on the bottom surface of the mounting plate 13. Fixed plates are symmetrically fixed on both sides of the bottom surface of the connecting plate 12, and a pressure roller 19 is rotatably mounted between the two fixed plates. The fixed plate and the mounting plate 13 both play a connecting role.

[0027] A discharge port 15 is provided on one side of the frame 2, and a baffle 5 is provided at the discharge port 15; the large particles remaining on the screen plate 9 after screening by the screen plate 9 can be discharged through the discharge port 15. When discharge is required, the baffle 5 can be rotated so that it no longer seals the discharge port 15, and the large particles on the screen plate 9 can be discharged with the help of existing tools.

[0028] Limit plates are fixedly mounted on the sides of the frame 2 at both ends of the discharge port 15. A rotating shaft 7 is rotatably mounted between the limit plates. A baffle 5 is fixedly mounted on the rotating shaft 7. A convex plate that matches the discharge port 15 is fixedly mounted on the side of the baffle 5 facing the discharge port 15. Two stoppers 6 are symmetrically mounted on the side of the baffle 5 away from the discharge port 15. When the baffle 5 is rotated, the stoppers 6 can be pressed against the surface of the frame 2, thereby causing the baffle 5 to assume an inclined shape.

[0029] A drive assembly for rotating the baffle 5 is mounted on one side of the frame 2. The assembly includes a motor, gear 17, and gear 2 18, and a protective frame 8 is positioned outside the assembly. A mounting shaft 16 is rotatably mounted on one side of the frame 2. The motor is fixedly mounted on one end of the shaft, and gear 17 is fixedly mounted on the shaft. One end of the rotating shaft 7 rotates through and extends to the outside of one of the stop plates. Gear 2 18 is fixedly mounted on the extended end of the shaft 7, and gears 17 and 18 mesh together for transmission.

[0030] The motor is a forward and reverse motor. An existing controller for controlling the motor is installed on the frame 2. When the motor is working, it can drive the mounting shaft 16 to rotate, thereby driving the gear 1 17 on the mounting shaft 16 to rotate. The gear 1 17 is engaged with the gear 2 18, driving the gear 2 18 to rotate. The gear 2 18 drives the rotating shaft 7 to rotate, thereby driving the baffle 5 to rotate, thereby playing the role of adjusting the state of the baffle 5.

[0031] During operation, after sand containing large particles and sand containing lumps are poured into the frame 2, the slider 11 can drive the connecting plate 12 to move, thereby driving the pressure roller 19 and the stirring rod 14 at the bottom of the connecting plate 12 to move. The pressure roller 19 can press the sand to break up the agglomerated sand and allow it to pass through the screening plate 9, while the stirring rod 14 can stir the sand to facilitate the sand to pass through the screening plate 9. By setting the pressure roller 19, it can be avoided that the agglomerated sand cannot pass through the screening plate 9 and is discharged, causing waste of raw materials.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
