Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides a concrete pouring anti-segregation layered vibration auxiliary flow guiding device, including a mixing tank 1, a U-shaped plate 2 fixedly connected to the upper surface of the mixing tank 1, a first motor 3 fixedly connected inside the U-shaped plate 2, a first sprocket 4 fixedly provided at the output end of the first motor 3, the outer wall of the first sprocket 4 rotatably connected to the inside of the mixing tank 1, a chain 5 meshing with the tooth end of the first sprocket 4, a second sprocket 6 meshing with the tooth end of the chain 5, a mixing column 7 fixedly connected inside the second sprocket 6, the outer wall of the mixing column 7 rotatably connected to the inside of the U-shaped plate 2 and the mixing tank 1, a U-shaped rod 8 fixedly connected inside the mixing column 7, the outer wall of the U-shaped rod 8 rotatably connected to the inside of the mixing tank 1, a feed inlet 9 fixedly connected to the upper surface of the mixing tank 1, a discharge outlet 10 fixedly connected to the lower surface of the mixing tank 1, and a support assembly provided on the lower surface of the mixing tank 1;

[0024] Specifically, the mixing tank 1 serves as a storage tank, provides fixed support for the U-shaped plate 2, and provides fixed support for the first motor 3. The first motor 3 drives the first sprocket 4, which in turn drives the chain 5 to rotate. The first sprocket 4 has a connecting rod inside, which rotates inside the mixing tank 1, thus assisting in supporting and limiting the first sprocket 4. The chain 5 drives the second sprocket 6, which in turn drives the mixing column 7 to rotate inside the U-shaped plate 2 and the mixing tank 1. The U-shaped plate 2 and the mixing tank 1 provide auxiliary support and limit the mixing column 7, which in turn drives the U-shaped rod 8 to fully mix the aggregate and the slurry, thereby ensuring that the aggregate and the slurry are uniformly mixed.

[0025] Reference Figure 1 and Figure 4 The support assembly includes a support column 11, the upper surface of which is fixedly connected to the lower surface of the mixing tank 1, and a base 12 is fixedly connected to the lower surface of the support column 11; a fixing block 13 is fixedly connected to the upper surface of the base 12, and a second motor 14 is fixedly connected inside the fixing block 13.

[0026] Specifically, the base 12 provides fixed support for the support column 11, which in turn provides fixed support for the mixing tank 1. The base 12 provides fixed support for the fixing block 13, which in turn provides fixed support for the second motor 14.

[0027] Reference Figure 4 A threaded rod 15 is fixedly installed at the output end of the second motor 14. A support block 16 is rotatably connected to the outer wall of the threaded rod 15. The lower surface of the support block 16 is fixedly connected to the upper surface of the base 12. A slider 17 is threadedly connected to the outer wall of the threaded rod 15. A rotating plate 18 is rotatably connected to the outer wall of the slider 17. A moving block 19 is rotatably connected to the inside of the rotating plate 18. A guide plate 20 is fixedly connected to the upper surface of the moving block 19. A limit post 21 is fixedly connected to the inside of the guide plate 20. A limit block 22 is rotatably connected to the outer wall of the limit post 21. The lower surface of the limit block 22 is fixedly connected to the upper surface of the base 12.

[0028] Specifically, the second motor 14 drives the threaded rod 15 to rotate inside the support block 16. The base 12 provides fixed support to the support block 16, which in turn provides auxiliary support and limits the threaded rod 15. The threaded rod 15 drives the slider 17, which in turn drives the rotating plate 18 to move. The rotating plate 18 drives the moving block 19, which in turn drives the guide plate 20 to rotate. The guide plate 20 drives the limiting post 21 to rotate inside the limiting block 22. The base 12 provides fixed support to the limiting block 22, which in turn limits the limiting post 21.

[0029] Working principle: When the device is needed, aggregate and slurry are fed into the mixing tank 1 through the feed inlet 9. Then, the first motor 3 inside the U-shaped plate 2 is started. The first motor 3 drives the first sprocket 4, which in turn drives the chain 5 to rotate. The chain 5 drives the second sprocket 6, which in turn drives the mixing column 7 to rotate inside the U-shaped plate 2 and the mixing tank 1. Thus, the mixing column 7 drives the U-shaped rod 8 to fully mix the aggregate and slurry, ensuring that the aggregate and slurry are mixed evenly, improving the fluidity of concrete, reducing the risk of blockage of the guide pipe, and enhancing the compactness of layered pouring.

[0030] After mixing, the concrete can be poured into the guide plate 20 through the discharge port 10, which in turn activates the second motor 14 inside the fixed block 13. The second motor 14 drives the threaded rod 15 to rotate inside the support block 16. The threaded rod 15 drives the slider 17, which in turn drives the rotating plate 18 to move. The rotating plate 18 drives the moving block 19, which in turn drives the guide plate 20 to rotate. The guide plate 20 drives the limiting column 21 to rotate inside the limiting block 22, thereby flexibly controlling the flow direction and speed of the concrete to meet the needs of different pouring positions and structural shapes, and reducing the risk of segregation. This device can not only prevent local segregation of concrete due to stagnation or uneven flow rate during the diversion process, ensuring uniform mixing of aggregate and slurry, but also improve the fluidity of concrete, reduce the risk of blockage in the diversion pipe, enhance the compactness of layered pouring, and flexibly control the flow direction and speed of concrete to meet the needs of different pouring positions and structural shapes, reduce the risk of segregation, and optimize the uniformity of concrete distribution, ensuring the layered vibration effect and improving the pouring quality.
