For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. The following is an explanation of the embodiments of the present utility model based on the overall structure of the present utility model.
[0021] Reference Figures 1 to 5In the embodiment of the utility model, a sand screening device for construction engineering includes: a sand screening box 1, a grinding tube 2 is fixedly connected to one end above the sand screening box 1, a slide rail support rod 3 is fixedly arranged at the other end above the sand screening box 1, a peep window 4 is arranged at one end outside the sand screening box 1, a discharge port 5 is opened at the other end outside the sand screening box 1, a sand receiving tray 6 is fixedly arranged on the side of the discharge port 5, a grinding net 7 is fixedly arranged below the grinding tube 2, a slide bar 8 is fixedly arranged on the side of the slide rail support rod 3, a slider 9 is slidably arranged on the side of the slider 8, a connecting plate 10 is fixedly connected to the side of the slider 9, a driving motor 11 is plugged above the connecting plate 10, a rotating rod 12 is rotatably connected to the bottom of the driving motor 11, a grinding disc 13 is rotatably connected to the bottom of the rotating rod 12, a material extraction pump 14 is fixedly connected to one side of the grinding tube 2, and a feed pipe 15 is fixedly connected to the side of the material extraction pump 14.
[0022] The above scheme is adopted: the grinding tube 2 continuously introduces sand into the grinding area through the suction pump 14 and the feed pipe 15, the grinding disc 13 rotates at high speed under the drive of the driving motor 11, and finely grinds the sand to ensure that the sand reaches the required fineness. The ground sand passes through the filtering effect of the grinding net 7 and falls into the sand screening box 1 for further screening. The setting of the window 4 enables the operator to observe the sand screening process in real time to ensure the screening quality.
[0023] A connecting seat 16 is fixedly provided on the upper part of the sand screening box 1, a pushing block telescopic push rod 17 is fixedly connected to the lower part of the connecting seat 16, a pushing block 18 is fixedly connected to the lower part of the pushing block telescopic push rod 17, a plug plate 19 is fixedly provided at one end of the inner side of the sand screening box 1, and a filter screen 20 is plugged into the side of the plug plate 19.
[0024] The above scheme is adopted: when a certain amount of sand accumulates on the filter screen 20 during the screening process, or the sand blocks the filter screen 20, the driving device inside the connecting seat 16 will be started, pushing the telescopic push rod 17 of the push block to extend, and then the push block 18 will knock on the filter screen 20. This knocking action can effectively remove the blocked sand on the filter screen 20 and maintain the continuity and efficiency of screening.
[0025] An adjustable telescopic rod 21 is fixedly provided at the lower part inside the sand screening box 1, a rotating seat 22 is fixedly provided above the adjustable telescopic rod 21, a connecting block 23 is rotatably connected above the rotating seat 22, a fixed plate 24 is fixedly connected above the connecting block 23, and a loading plate 25 is fixedly provided above the fixed plate 24.
[0026] The above scheme is adopted: the adjustable telescopic rod 21 arranged inside the sand screening box 1 can adjust the length as needed, so as to change the inclination angle of the material carrying plate 25 by rotating the seat 22 and the connecting block 23. This design enables the sand to slide smoothly onto the material carrying plate 25 after the screening is completed, and when the sand needs to be discharged, the material carrying plate 25 can be tilted by adjusting the adjustable telescopic rod 21, thereby guiding the sand to the discharge port 5 of the sand screening box 1. This flexibility ensures that the sand can be collected and discharged efficiently and orderly, thereby improving the overall work efficiency.
[0027] The left and right sides of the sand screening box 1 are provided with discharge ports 5 and sand receiving trays 6. The rotating rod 12 passes through the connecting plate 10 and is rotatably connected to the driving motor 11. The connecting plate 10 slides up and down through the sliding rod 8, thereby driving the rotating rod 12 and the grinding disc 13 to rise and fall. The suction pump 14 introduces sand into the grinding pipe 2, and the ground sand falls into the inside of the sand screening box 1 from the grinding net 7.
[0028] The above scheme is adopted: the sliding system composed of the slide rail support rod 3 and the slide rod 8 allows the grinding disc 13 to be adjusted in height. By sliding the slider 9, the distance between the grinding disc 13 and the grinding net 7 can be easily adjusted to adapt to sand with different grinding requirements. This design not only improves the flexibility of the device, but also ensures the consistency of the grinding effect.
[0029] A driving device is arranged inside the connecting seat 16 , and the pushing block 18 can knock the sand remaining on the filter screen 20 through the driving of the connecting seat 16 , so that the sand falls down, and the pushing block 18 is located above the filter screen 20 .
[0030] By adopting the above scheme: by knocking the filter screen 20, it can be ensured that the sand can always pass through the filter screen 20 smoothly during the screening process, avoiding the decrease in screening efficiency due to blockage of the filter screen 20, which not only improves work efficiency, but also ensures the quality of the screened sand.
[0031] There are multiple groups of adjustable telescopic rods 21, and every two groups of adjustable telescopic rods 21 can be adjusted to different heights. By adjusting the telescopic rods 21 and pushing the rotating seat 22 up and down, the connecting block 23 is rotated, so that the loading plate 25 can be tilted at a certain angle, and the sand above the loading plate 25 is guided to the discharge port 5.
[0032] The above solution is adopted: the rotating connection design of the rotating seat 22 and the connecting block 23 ensures the stability and smoothness when adjusting the angle of the loading plate 25, avoiding jamming or damage caused by mechanical friction. The fixed plate 24 provides a stable support for the loading plate 25, ensuring the safety and reliability of the sand during the discharge process.
[0033] The working principle of the utility model is as follows: the device first introduces sand into the grinding tube 2 through the feed pipe 15 by the pumping pump 14. In the grinding tube 2, the sand is ground to the required fineness by the rotation of the grinding disc 13. The ground sand falls into the sand screening box 1 through the filtering effect of the grinding net 7. The sand is preliminarily screened on the filter net 20. In order to further improve the screening effect, a connecting seat 16 is provided above the inside of the sand screening box 1. Below the connecting seat 16, a filter 20 is provided. A push block 18 is fixed below the push block 17. When a certain amount of sand accumulates on the filter screen 20 during screening, or the sand blocks the filter screen 20, the driving device inside the connecting seat 16 will start, pushing the push block 18 to knock the filter screen 20, so that the sand remaining on the filter screen 20 falls off, maintaining the continuity and efficiency of screening. The screened sand falls on the loading plate 25 at the bottom of the sand screening box 1, and the loading plate 25 is supported by the fixed plate 24 and the connecting block 23. The connecting block 23 is connected to the adjusting telescopic rod 21 through the rotating seat 22. The adjusting telescopic rod 21 can be set in multiple groups. By adjusting the length of different groups of adjusting telescopic rods 21, the inclination angle of the loading plate 25 can be changed. When it is necessary to discharge sand, the adjusting telescopic rod 21 will push the rotating seat 22 to move up and down, so that the connecting block 23 drives the loading plate 25 to tilt, and guides the sand to the discharge port 5 of the sand screening box 1. The left and right sides of the sand screening box 1 are provided with a discharge port 5 and a sand receiving tray 6, which can be adjusted according to actual needs. It is necessary to choose which side to discharge the sand from. When the sand is discharged from the discharge port 5, it will fall on the sand receiving tray 6, which is convenient for collection and processing. In addition, a slide rail support rod 3 is arranged above the sand screening box 1, and a slide bar 8 is fixed on the side of the slide rail support rod 3. A slider 9 is slidably connected to the slider 8, and a connecting plate 10 is connected to the side of the slider 9. A drive motor 11 is inserted above the connecting plate 10. The drive motor 11 is connected to the grinding disc 13 through a rotating rod 12. The height of the grinding disc 13 can be adjusted to adapt to sand with different grinding requirements.
[0034] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
