Description

Technical Field

[0001] This utility model belongs to the field of concrete mixing technology, and in particular relates to a concrete anti-solidification mixing device. Background Technology

[0002] Concrete is one of the most widely used building materials in modern civil engineering. It is made by mixing cementitious materials, aggregates, water, and admixtures in a certain proportion, and then forming artificial stone with a certain strength after stirring, molding, and hardening. The cement hydration reaction begins as soon as water is added to the concrete and the initial setting time is usually 45 minutes to 1 hour (depending on the type of cement). If the concrete is transported from the batching plant to the construction site and the unloading is delayed, or the construction preparation is insufficient (such as pump truck malfunction or incomplete formwork), causing the time spent there to exceed the initial setting time, it will gradually lose its plasticity and become unusable for pouring.

[0003] When using concrete in small batches, temporary containers are often used to store it. Since the concrete is not used up all at once, it needs to be carried to different locations during repair work. A bucket of concrete may take a long time to be used up. However, if the concrete is stored in the container for a long time, it will easily harden and become unusable, and cleaning will be troublesome. Utility Model Content

[0004] To address the aforementioned problems, this invention proposes a concrete anti-solidification mixing device to more accurately resolve the problems described above.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model proposes a concrete anti-solidification mixing device, including a base plate, a vertical plate fixedly connected to the upper surface of the base plate, a square through groove on the vertical plate, a sliding plate slidably connected in the square through groove, a mixing assembly installed on the sliding plate, and a limiting ring provided on the upper surface of the base plate, the limiting ring being located below the mixing assembly.

[0007] In one example, a support plate is fixedly connected to one side of the sliding plate, located on the other side of the vertical plate. A horizontal plate is fixedly connected to one side of the vertical plate above the support plate. A servo motor is mounted on the horizontal plate, and a screw is fixedly connected to the main shaft of the servo motor. The screw passes through the support plate and is threadedly connected to the support plate.

[0008] In one example, the stirring assembly includes a drive motor, which is fixedly connected to a sliding plate. The main shaft of the drive motor is fixedly connected to a first pulley. A rotating column is rotatably connected to the sliding plate, and the rotating column passes through the sliding plate. A second pulley is fixedly connected to the outside of the rotating column. The first pulley and the second pulley are connected by a belt. A vertical rod is slidably connected to the rotating column, and a plurality of stirring rods are fixedly connected to the lower end of the vertical rod.

[0009] In one example, a fixing ring is fixedly connected to the upper surface of the sliding plate, and multiple arc-shaped blocks are fixedly connected to the upper surface of the fixing ring. A round rod is fixedly connected to one side of the vertical rod, and the round rod presses against the upper surface of the fixing ring.

[0010] In one example, the centers of the fixed ring, the vertical rod, and the rotating column are on the same axis, and the center of the rotating column and the center of the limiting ring are on the same axis.

[0011] In one example, two mounting rods are fixedly connected to the upper surface of the sliding plate, and a circular cylinder is fixedly connected between the mounting rods. The bottom of the circular cylinder is open. A piston is slidably connected inside the circular cylinder, and a spring is fixedly connected between the piston and the circular cylinder. A circular shell is fixedly connected to the center of the piston. The circular shell has through holes on both the upper and lower sides. The circular shell is fixedly connected to a vertical rod. The vertical rod and the stirring rod have the same channel inside, and the channel communicates with the circular shell. The stirring rod has multiple air holes on its side wall.

[0012] In one example, the upper surface of the cylindrical tube is provided with a through groove, the inner wall of the through groove is provided with a mounting groove, a first rotating plate is rotatably connected in the mounting groove, and a torsion spring is provided at the connection point. A second rotating plate is rotatably connected in the circular shell, and a torsion spring is provided at the connection point.

[0013] The concrete anti-hardening mixing equipment proposed in this utility model can bring the following beneficial effects:

[0014] Firstly, by setting up a mixing component, the container holding the concrete is placed inside the limiting ring on the bottom plate. The sliding plate descends, allowing the mixing component to extend into the container. The drive motor starts and drives the vertical rod and rotating column to rotate on the sliding plate through the first and second pulleys. The vertical rod drives the mixing rod with its lower end extending into the concrete to rotate, continuously mixing the concrete and preventing it from solidifying.

[0015] Secondly, by setting up an arc-shaped block and a circular cylinder, the vertical rod rotates slowly. Under the action of gravity, the circular rod on the vertical rod presses against the fixed ring. When the circular rod moves to the arc-shaped block, the vertical rod pulls the mixing rod upward. When the circular rod slides down from the arc-shaped block, the vertical rod descends and resets, allowing the mixing rod to be at different depths to mix the concrete. When the vertical rod is pushed upward, it pushes the piston to slide upward, compressing the spring and causing air pressure to squeeze the first rotating plate, blocking the through groove. At the same time, air pressure squeezes the second rotating plate, causing it to rotate downward and open the through hole, allowing airflow to enter the channel between the circular shell and the vertical rod. The airflow is then ejected through the air hole on the mixing rod. As the mixing rod rotates, it slides vertically to adjust the height, and the airflow ejected through the air hole impacts the concrete, further improving the mixing effect.

[0023] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0024] like Figures 1-4 As shown in the figure, an embodiment of this utility model proposes a concrete anti-curing mixing device, including a base plate 1, a vertical plate 2 fixedly connected to the upper surface of the base plate 1, a square through groove on the vertical plate 2, a sliding plate 3 slidably connected in the square through groove, a mixing assembly 4 installed on the sliding plate 3, a limiting ring 5 on the upper surface of the base plate 1 located below the mixing assembly 4, a support plate 6 fixedly connected to one side of the sliding plate 3 located on the other side of the vertical plate 2, and a horizontal plate 7 fixedly connected to one side of the vertical plate 2 above the support plate 6, with a servo motor 8 installed on the horizontal plate 7. The main shaft of the servo motor 8 is fixedly connected to the screw 9, which passes through the support plate 6 and is threadedly connected to the support plate 6. In use, the container holding the concrete is placed in the limiting ring 5 on the base plate 1, so that the container is aligned with the mixing component 4. Then, the servo motor 8 is started and the sliding plate 3 is lowered through the threaded rod, so that the mixing component 4 extends into the container. The mixing component 4 rotates slowly to mix the concrete, making the concrete flow and avoiding solidification and waste. At the same time, appropriate chemical reagents, such as retarders, can be added when the mixing component 4 is mixing the concrete.

[0025] like Figure 2 and Figure 3 As shown, the mixing assembly 4 includes a drive motor 41, which is fixedly connected to the sliding plate 3. The main shaft of the drive motor 41 is fixedly connected to a first pulley. A rotating column 43 is rotatably connected to the sliding plate 3, and the rotating column 43 passes through the sliding plate 3. A second pulley is fixedly connected to the outside of the rotating column 43. The first pulley and the second pulley are connected by a belt. A vertical rod 44 is slidably connected to the rotating column 43. Multiple mixing rods 45 are fixedly connected to the lower end of the vertical rod 44. When mixing concrete, the drive motor 41 starts, and drives the vertical rod 44 and the rotating column 43 to rotate on the sliding plate 3 through the first pulley and the second pulley. The vertical rod 44 drives the mixing rods 45, whose lower ends extend into the concrete, to rotate, thereby continuously mixing the concrete and preventing it from solidifying.

[0026] like Figure 2 and Figure 3 As shown, a fixed ring 10 is fixedly connected to the upper surface of the sliding plate 3, and multiple arc-shaped blocks 11 are fixedly connected to the upper surface of the fixed ring 10. A round rod 12 is fixedly connected to one side of the vertical rod 44. The round rod 12 presses against the upper surface of the fixed ring 10. The centers of the fixed ring 10, the vertical rod 44, and the rotating column 43 are on the same axis. The center of the rotating column 43 and the center of the limiting ring 5 are on the same axis. When the drive motor 41 rotates slowly, it drives the vertical rod 44 to rotate slowly. Under the action of gravity, the round rod 12 on the vertical rod 44 presses against the fixed ring 10. When the round rod 12 moves to the arc-shaped block 11, the vertical rod 44 pulls the stirring rod 45 up. When the round rod 12 slides down from the arc-shaped block 11, the vertical rod 44 descends and resets, so that the stirring rod 45 is at different depths to stir the concrete and improve the stirring effect. The vertical rod 44 can slide vertically on the rotating column 43, and the rotating column 43 can drive the vertical rod 44 to rotate.

[0027] like Figure 3 and Figure 4As shown, two mounting rods 13 are fixedly connected to the upper surface of the sliding plate 3, and a circular cylinder 14 is fixedly connected between the mounting rods 13. The bottom of the circular cylinder 14 is open, and a piston 15 is slidably connected inside the circular cylinder 14. A spring 16 is fixedly connected between the piston 15 and the circular cylinder 14. A circular shell 17 is fixedly connected to the center of the piston 15. The circular shell 17 has through holes on both the upper and lower sides. The circular shell 17 is fixedly connected to the vertical rod 44. The vertical rod 44 and the stirring rod 45 have the same channel inside, which communicates with the circular shell 17. The stirring rod 45 has multiple air holes on its side wall. The upper surface of the circular cylinder 14 has a through groove, and the inner wall of the through groove has a mounting groove. A first rotating plate 18 is rotatably connected inside the mounting groove, and a torsion spring is provided at the connection. A second rotating plate 19 is rotatably connected inside the circular shell 17, and a torsion spring is provided at the connection. When the arc-shaped block 11 pushes the vertical rod 44 upward through the circular rod 12... The vertical rod 44 pushes the piston 15 upward, compressing the spring 16. The air pressure squeezes the first rotating plate 18, causing it to block the through groove. At the same time, the air pressure squeezes the second rotating plate 19, causing it to rotate downward and open the through hole. This allows airflow to enter the channel between the circular shell 17 and the vertical rod 44, and then spray out through the air hole on the stirring rod 45. As the stirring rod 45 rotates, it slides vertically to adjust its height. Simultaneously, airflow is sprayed out through the air hole, impacting the concrete and further improving the mixing effect. When the circular rod 12 slides off the arc-shaped block 11, the vertical rod 44 descends under the force of gravity and the push of the spring 16. Under the action of the pressure difference, it squeezes open the first rotating plate 18, allowing airflow to enter the circular cylinder 14. Meanwhile, the second rotating plate 19 is pressed tightly against the circular shell 17, blocking the through hole and preventing the stirring rod 45 from drawing water from the concrete through the air hole under the action of the air pressure difference.

[0028] Working principle: The container holding the concrete is placed in the limiting ring 5 on the base plate 1, aligning the container with the mixing assembly 4. Then, the servo motor 8 starts and controls the sliding plate 3 to descend via the threaded rod, allowing the mixing assembly 4 to extend into the container. The drive motor 41 starts and drives the vertical rod 44 and the rotating column 43 to rotate on the sliding plate 3 via the first and second pulleys. When the arc block 11 pushes the vertical rod 44 upward via the round rod 12, the vertical rod 44 pushes the piston 15 to slide upward, compressing the spring 16. The air pressure squeezes the first rotating plate 18, causing the first rotating plate 18 to block the through groove. At the same time, the air pressure squeezes the second rotating plate 19, causing the second rotating plate 19 to rotate downward and open the through hole, allowing airflow to enter the channel on the circular shell 17 and the vertical rod 44. The airflow is ejected through the air hole on the mixing rod 45. As the mixing rod 45 rotates, it slides vertically to adjust the height. At the same time, the airflow is ejected through the air hole, impacting the concrete and further improving the mixing effect of the concrete.
