DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] The utility model provides a sand screening machine for water transportation engineering, as Figures 1-4 shown. The sand screening machine includes two support plates 1. A discharge hole 21 is formed in each support plate 1. One side of a box body 3 is fixedly connected with a discharge plate 22. The discharge plate 22 is arranged in the discharge hole 21. When the support plate 1 is on a horizontal ground, it can provide good support stability for the box body 3. At the same time, the discharge hole 21 enables the discharge plate 22 to have a storage space, so that when the discharge plate 22 moves with the box body 3, it will not be blocked by the support plate 1 to limit the movement process of the box body 3. And the discharge plate 22 enables the stones pushed by the shoveling edge 15 to have the condition of being discharged outward, preventing the stones from remaining in the box body 3 because they cannot be discharged.

[0023] Two through holes 23 are formed in the support plate 1. The outer wall of a slider 14 is slidably attached to the inner wall of the through hole 23. A discharge port 24 is formed in the bottom of the box body 3. The through hole 23 enables the slider 14 to have a moving space, so that when the guide block moves the slider 14 in the through hole 23, it has a support point and good stability, preventing the guide teeth 13 from being suspended and unable to form normal meshing movement with the linkage teeth 12. The discharge port 24 enables the fine sand falling into the box body 3 after filtration to have a discharge space, facilitating the use of the fine sand.

[0024] A spring 2 is fixedly connected to one side of each of the two support plates 1. The end of the spring 2 away from the support plate 1 is fixedly connected to the box body 3. The spring 2 enables the box body 3 to have an elastic adjustment force. Thus, when a cam 7 presses the support plate 1, the box body 3 can shake by using the elastic force of the spring 2 to improve the screening effect of this device. And the box body 3 enables the fine sand to have a storage space, facilitating the centralized discharge and use of the filtered fine sand;

[0025] Two telescopic rods 19 are fixedly connected to both sides of the box body 3. The end of the telescopic rod 19 away from the box body 3 is fixedly connected to one side of the support plate 1. The telescopic rod 19 enables the box body 3 to have a support point, preventing the spring 2 from being bent due to being unable to bear the weight of the box body 3, and enabling the box body 3 to shake smoothly by using the telescopic property of the telescopic rod 19;

[0026] A notch 20 is formed in one side of the box body 3. A second bearing 9 is arranged in the notch 20. The notch 20 enables the second bearing 9 to have a moving space, so that the second bearing 9 can be driven to move by an electric push rod 16 according to the cleaning requirement of the stones on the filter net 17, so as to achieve the corresponding meshing state between the second gear 11 and the first gear 8, so as to achieve the corresponding cleaning process of the stones at an appropriate time according to the requirement;

[0027] The inner wall of the box body 3 is fixedly connected with a filter screen 17. The filter screen 17 enables the fine sand to have a screening point, so that the stones in the fine sand can be separated, thereby improving the quality of the fine sand for use;

[0028] A first bearing 4 is arranged inside the box body 3. A roller 5 is rotatably connected to the inside of the box body 3 through the first bearing. A motor 6 for driving the roller 5 to rotate is fixedly connected to the outer wall of the box body 3. By using the output shaft of the motor 6, when the motor 6 operates, the roller 5 can be driven to rotate smoothly, so that the two cams 7 can be in a rotating state;

[0029] Two motor fixing blocks 18 are fixedly connected to the outer wall of the motor 6. The side of the motor fixing block 18 away from the motor 6 is fixedly connected to the support plate 1. The motor fixing block 18 enables the motor 6 to have a fixing point, thereby effectively reducing the adverse effects brought by the vibration generated when the motor 6 operates;

[0030] Two cams 7 are fixedly connected to the outer wall of the roller 5. When the convex surface of the cam 7 rotates to contact the support plate 1, the support plate 1 can be squeezed to cause the box body 3 to shake by the elastic force provided by the spring 2;

[0031] A first gear 8 is fixedly connected to the outer wall of the roller 5. A second bearing 9 is arranged inside the box body 3. A rotating shaft 10 is rotatably connected to the inside of the box body 3 through the second bearing 9. A second gear 11 meshing with the first gear 11 is fixedly connected to the outer wall of the rotating shaft 10. The second gear 11 meshes with the first gear 8. When the roller 5 drives the first gear 8 to rotate, the second gear 11 meshing with the first gear 8 can drive the rotating shaft 10 to rotate, so as to achieve the purpose that the rotating shaft 10 can drive the linkage tooth 12 to rotate;

[0032] A linkage tooth 12 is fixedly connected to the outer wall of the rotating shaft 10. A guiding tooth 13 meshing with the linkage tooth 12 is arranged on one side of the box body 3 close to the rotating shaft 10. Sliders 14 inserted into the inside of the support plate 1 are fixedly connected to both sides of the guiding tooth 13. A scraping edge 15 for scraping the filter screen 17 is fixedly connected to the top of the guiding tooth 13. When the linkage tooth 12 rotates, the guiding tooth 13 meshing with the linkage tooth 12 can drive the scraping edge 15 to move back and forth, so that the scraping edge 15 can push the stones on the filter screen 17 to the two discharge plates 22 respectively for discharging, preventing more stones from affecting the filtering effect of the filter screen 17;

[0033] An electric push rod 16 is fixedly connected to the outer wall of the second bearing 9. The bottom end of the electric push rod 16 is fixedly connected to the upper part of the box body 3. The electric push rod 16 can drive the second bearing 9 to move up and down, so as to perform corresponding cleaning work on the stones according to the needs, preventing the scraping edge 15 from randomly moving and pushing the fine sand and stones to the discharge plate 22 for discharging while the fine sand is in a filtering state.

[0034] Working principle:

[0035] When the screening work of fine sand needs to be carried out using this device, first pour the fine sand collectively onto the filter screen 17, and then start the motor 6, so that the output shaft of the motor 6 drives the roller 5 to rotate, causing the roller 5 to drive the two cams 7 to rotate. When the convex surfaces of the two cams 7 rotate to contact the two support plates 1 respectively, the extrusion force can be provided to cause the box body 3 to use the elastic force of the spring 2 to achieve the shaking process, so as to separate the fine sand on the filter screen 17 from the stones. At the same time, the filtered fine sand can fall into the box body 3 and be discharged through the discharge port 24.

[0036] When it is necessary to clean the stones on the filter screen 17, use the electric push rod 16 to drive the second bearing 9 to move downward, so that the second gear 11 can be engaged with the first gear 8. When the first gear 8 rotates, the second gear 11 engaged with the first gear 8 can drive the rotating shaft 10 to rotate. When the rotating shaft 10 drives the linkage tooth 12 to rotate, the guiding tooth 13 engaged with the linkage tooth 12 can drive the shoveling edge 15 to move back and forth, so as to achieve the purpose that the shoveling edge 15 can push the remaining stones on the filter screen 17 to the two discharge plates 22 for discharge.

[0037] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, should be covered within the protection scope of the present invention.
