A second guide rod 36 is provided at the center of the interior above the stirring rod 9. A groove 38 is provided at the center of the interior below the connecting column 31. A second spring 37 is provided on the outside of the second guide rod 36. One side of each first spring 35 is fixedly connected to the bottom of the slider 33, and the other side of each first spring 35 is fixedly connected to the interior above the stirring rod 9. One side of the second spring 37 is provided at the bottom of the connecting column 31, and the other side of the second spring 37 is fixedly connected to the center of the interior above the stirring rod 9. A bracket 2 is provided on the outside of the bottom of the mixing box 1. An outlet 5 is provided at the bottom of the mixing box 1, and an inlet 7 is provided at the top of the mixing box 1.

[0026] The overall effect achieved by Embodiment 1 is as follows: the relevant components can improve the stability of the traditional anti-segregation concrete mixing device during mixing through mechanical transmission. The function of setting the arc plate 32 is that the top of the arc plate 32 is set with a rigid plate to drive the mixing mechanism 4 to rotate, and the bottom of the arc plate 32 is set with a soft plate to provide a buffering effect. The function of setting the first guide rod 34 and the second guide rod 36 is to prevent abnormal twisting when the first spring 35 and the second spring 37 are deformed. The function of setting the strong first spring 35 and the second spring 37 is to support the rotation of the mixing mechanism 4. When encountering vibration caused by contact with hard objects (such as stones), this mechanical transmission method improves the efficiency of the motor and extends its service life by setting a stabilizing mechanism.

[0027] Example 2, as Figures 1-6 As shown, the stirring mechanism 4 includes multiple first arc-shaped plates 43, multiple stirring plates 41 are staggered on the outer side of the stirring rod 9, multiple first stirring columns 42 are provided on the outer side of the stirring rod 9, and the side of each first stirring column 42 away from the stirring rod 9 is fixedly connected to the side end of the first arc-shaped plate 43. Multiple first scrapers 44 are provided on the side of each first arc-shaped plate 43 near the inner wall of the mixing tank 1. Multiple second stirring columns 45 are provided on the outer side below the stirring rod 9. A second arc-shaped plate 47 is fixedly connected on the side of each second stirring column 45 away from the stirring rod 9. Multiple second scrapers 48 are provided on the side of each second arc-shaped plate 47 near the inner wall of the mixing tank 1.

[0028] The effect achieved by the entire embodiment 2 is as follows: by setting the stirring mechanism 4, the stirring rod 9 drives the first stirring column 42, the first arc plate 43, the stirring plate 41, the second stirring column 45 and the second arc plate 47 to rotate, and the first scraper 44 and the second scraper 48 scrape the inner wall of the stirring box 1 as the first arc plate 43 and the second arc plate 47 rotate, thereby promoting the stirring effect.

[0029] The working principle of the entire equipment is as follows: Installation and inspection phase: Before starting the test, ensure that all parts of the structure are in a stable state to prevent any part of the structure from malfunctioning after the work is completed.

[0030] Concrete stage: During concrete mixing, open valve 6 at inlet 7 to inject concrete into the mixing tank 1. After injection, close valve 6 and start motor 8. The output shaft of motor 8 drives the mixing rod 9 to rotate via connecting column 31. Simultaneously, the mixing rod 9 drives the first mixing column 42, the second mixing column 45, the first arc plate 43, the second arc plate 47, the first scraper 44, and the second scraper 48 to scrape and mix the inner wall of the mixing tank 1. When encountering hard stones or other hard materials, the mixing rod 9 drives the second guide rod 36 to slide inside the chute 38. When the second guide rod 36 slides inside the chute... The second spring 37 deforms, and the stirring rod 9 drives the stirring mechanism 4 to slide vertically back and forth inside the mixing tank 1. At the same time, the top of the slider 33 abuts against the bottom of the arc plate 32, and the bottom of the arc plate 32 buffers it. Meanwhile, the first spring 35 deforms. When the stirring mechanism 4 does not touch hard materials such as stones, the output shaft of the motor 8 drives the stirring rod 9 and the stirring mechanism 4 to rotate through the connecting column 31 and the arc plate 32 to stir the concrete. After the stirring is completed, the motor 8 is turned off, and then the valve body 6 at the outlet 5 is opened to release the stirred concrete.
