[0002] The sand box is used for unloading in the construction of cast-in-place beams supported by steel pipe piles. After the Bailey beam supported by steel pipe piles is erected, the construction of cast-in-place beams begins. After the construction of cast-in-place beams is completed, the support needs to be removed. At this time, it is difficult to remove the support because the weight of the beam is all on the support. It is not easy to remove the support. This requires us to set up a sand box between the steel pipe piles and the distribution beam in advance when making the support. The sand box acts as a jack.

[0003] After searching, the patent with announcement number CN215354509U discloses a non-settling sand box for civil engineering, including a box body and a feeding pipe, the feeding pipe is fixedly arranged at the center of the upper side wall of the box body, and a corresponding first screen is arranged in the feeding pipe, the inner walls on both sides of the box body are symmetrically provided with tilting blocks, and a second screen is slidably and telescopically connected between the two tilting blocks, a driving motor is fixedly arranged on the outer wall of one side of the box body, and a hollow cylinder coinciding with the axis of the output shaft of the driving motor is fixedly arranged on the inner wall of the box body, and the output shaft of the driving motor is fixedly connected with a rotating rod through the side wall of the box body, and a matching bearing is arranged at the connection between the side wall of the box body and the output shaft of the driving motor, and the end of the rotating rod away from the output shaft of the driving motor is rotatably connected to the inner wall of the box body, and a reciprocating thread is arranged in the middle of the rotating rod. The utility model greatly improves the screening efficiency, and the screening process is carried out in the box body, which prevents a large amount of dust from directly spreading to the outside and polluting the air.

[0004] However, the above technical solution has the following problems: when sand is injected into the box, the sand will block the strip opening and affect the driving of the rotating rod to move the nut, which can easily cause the rotating rod in the opening to wear and get stuck, affecting the use of the box and reducing the practicality of the box. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art that when sand is injected into the box, the sand will block the strip opening and affect the driving of the rotating rod to move the nut, thereby easily causing the rotating rod in the opening to wear and get stuck, affecting the use of the box and reducing the practicality of the box, and a non-sedimentation sand box is proposed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0025] The box cover 2 is firmly fixed to the top of the box body 3 by bolts, ensuring the sealing of the box body 3. The No. 1 filter screen 8 is arranged inside the box body 3 and is designed to be in an inclined state to facilitate the screening and flow of gravel. The top of the box cover 2 is provided with an addition hole, and the addition pipe 1 is connected to the addition hole and fixed to the top of the box cover 2 by bolts, so as to facilitate the addition of gravel to be screened into the sand box. In addition, the No. 2 filter screen 12 is arranged inside the addition pipe 1 to perform preliminary screening on the gravel entering the sand box to prevent large particles or foreign matter from entering the box body 3.

[0026] In order to screen the gravel more effectively, the sand box is also provided with a shaking mechanism, which includes two synchronous motors 4, a controller 7, two cams 11 and four connecting blocks 13. The two synchronous motors 4 are respectively fixed on one side of the box body 3, and their output shafts penetrate the box body 3 and extend to the inside thereof, and are rotatably connected to the box body 3. One end of the two output shafts is respectively fixedly connected to one side of the two cams 11. When the motor rotates, it drives the cams 11 to perform periodic motion. The tops of the two cams 11 are tightly attached to both sides of the bottom of the No. 1 filter screen 8. The reciprocating motion of the cams 11 causes the No. 1 filter screen 8 to shake, thereby achieving the screening of the gravel.

[0027] In addition, the controller 7 is fixed on one side of the box body 3, and is used to control parameters such as the start, stop and speed of the synchronous motor 4 to achieve precise control of the shaking mechanism. One side of the four connecting blocks 13 is fixedly connected to the inner wall of the box body 3, and two rotating columns are rotatably connected between them. Both rotating columns are fixedly provided with rotating rings, and the outer side of the rotating ring is fixedly connected with a rotating rod, and one end of the rotating rod is fixedly connected to both sides of one side of the No. 1 filter 8. Such a design allows the No. 1 filter 8 to shake smoothly under the push of the cam 11 without deviation or distortion.

[0028] The present application can be used in the sand box field, and can also be used in other fields applicable to the present application.

[0031] L-shaped blocks 9 are fixedly connected on both sides of the top of the No. 1 filter screen 8. These L-shaped blocks 9 can effectively prevent large pieces of gravel from falling from the top of the filter screen during the screening process, thereby ensuring the efficiency and accuracy of the screening. In addition, a rubber pad 10 is fixedly connected to one side of the bottom of the No. 1 filter screen 8. The rubber pad 10 is located between the cam 11 and the No. 1 filter screen 8, which can reduce the collision damage between the two and reduce noise, thereby improving the service life and use environment of the sand box.

[0032] In order to support the synchronous motor 4, a side plate 5 is fixedly connected to one side of the box body 3, and triangular blocks 6 are fixed to both sides of the bottom of the side plate 5 by bolts. These triangular blocks 6 can increase the stability of the support and ensure the stability of the motor during use.

[0033] The shape of the No. 2 filter screen 12 is designed to be convex, and such a design can effectively reduce the clogging of sand and gravel in the filter screen and improve the screening efficiency.
