Description

Technical Field

[0001] The utility model relates to the technical field of concrete mixing devices, in particular to a mixing device for concrete construction. Background Art

[0002] Concrete is an artificial stone material made of cement, sand, aggregate (such as crushed stone or crushed sand) and water in a certain proportion. In concrete, cement plays the role of a gelling agent, bonding sand and aggregate together to form a solid stone structure. Mixing can fully mix raw materials such as cement, sand, and aggregate to ensure that the internal components of the concrete are evenly distributed, avoiding voids or unevenness, thereby improving the strength and stability of the concrete. Therefore, a mixing device for concrete construction is needed.

[0003] At present, the mixing device for concrete construction often outputs water through the lower nozzle at the bottom of the spray rod and the side nozzles on both sides. The lower nozzle sprays high-pressure water to spray and flush the inside of the mixing tank body, thereby flushing out the residual concrete in the concrete mixing device and improving the flushing efficiency.

[0004] However, this method cannot automatically discharge materials when used. Manual discharge requires additional manpower, which increases the labor cost of the construction site. Especially for large-scale projects or situations where frequent discharge is required, the cost will be more significant. Manual discharge is difficult to ensure the accuracy and consistency of the discharge volume, which can easily lead to an imbalance in the concrete mix ratio and affect the quality and performance of the concrete.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The prepared dry and wet materials are added into the inner tank 2 through a special feed pipe 3, and then the motor 6 is started. The output end of the motor 6 drives the shaft 7 to rotate. The rotation of the shaft 7 causes the active bevel gear 11 thereon to start rotating. The active bevel gear 11 is meshedly connected with the driven bevel gear 12, so the driven bevel gear 12 will also rotate with the rotation of the active bevel gear 11. The rotation of the driven bevel gear 12 further drives the rotation of the transmission rod 13. The transmission rod 13 is connected with the fixing ring 14 and the disc 16, so their rotation will also be realized with the rotation of the transmission rod 13. The rotation of the fixing ring 14 causes the stirring blades thereon to rotate. The blade 15 starts to rotate, and the rotation of the disc 16 causes the stirring rod 17 to rotate accordingly. Under the joint action of the stirring blade 15 and the stirring rod 17, the materials are fully stirred and mixed in the inner tank 2, ensuring the uniformity and quality of the concrete. During the mixing process, the rotation of the rotating shaft 7 also drives the rotation of the driving gear 8. The driving gear 8 and the driven gear 9 are meshed with each other, so the driven gear 9 will also rotate with the rotation of the driving gear 8. The rotation of the driven gear 9 further drives the rotation of the rotating rod 10, so that the entire inner tank 2 can rotate. When the discharge port 18 is aligned with the discharge pipe 19, the material inside the inner tank 2 can be discharged smoothly.

[0026] Reference Figure 1-Figure 3A screening bucket 28 is fixedly connected to the bottom of the outer tank 1, a placing plate 20 is fixedly connected to the left part of the screening bucket 28, a motor 21 is fixedly connected to the upper part of the placing plate 20, a rotating shaft 22 is fixedly connected to the output end of the motor 21, cams 23 are fixedly connected to the outer sides of the rotating shaft 22, a sieve plate 24 is provided on the upper part of the cam 23, the sieve plate 24 is slidably connected to the inside of the screening bucket 28, a discharge pipe 27 is provided at the rear part of the screening bucket 28, limiting columns 25 are fixedly connected to both sides of the bottom of the outer tank 1, the sieve plate 24 is slidably connected to the outside of the limiting column 25, a buffer spring 26 is sleeved on the outside of the limiting column 25, one end of the buffer spring 26 is fixedly connected to the bottom of the outer tank 1, and the other end of the buffer spring 26 is fixedly connected to the upper part of the sieve plate 24.

[0027] The concrete material discharged through the discharge pipe 19 is accurately transported to the upper part of the screen plate 24. Next, the motor 21 is started. The output end of the motor 21 is closely connected with the rotating shaft 22. Driven by the motor 21, the rotating shaft 22 starts to rotate. As the rotating shaft 22 rotates, the cam 23 also starts to rotate. As a key component of the screening device, the cam 23 can ensure that the screen plate 24 can achieve stable up and down movement outside the limit column 25. During the movement, the screen plate 24 will squeeze the buffer spring 26. The existence of the buffer spring 26 not only plays a buffering role, making the movement of the screen plate 24 more stable, but also its elastic effect can make the screen plate 24 shake up and down inside the screening bucket 28. This shaking effect allows the concrete material to be fully screened on the screen plate 24. Finally, the screened concrete material is discharged outward through the discharge pipe 27.

[0028] Working principle: First, add dry material and wet material into the inner tank 2 through the feed pipe 3, start the motor 6, the output end of the motor 6 drives the shaft 7 to rotate, the rotation of the shaft 7 drives the active bevel gear 11 to rotate, the active bevel gear 11 drives the meshing driven bevel gear 12 to rotate, the driven bevel gear 12 drives the transmission rod 13 to rotate, the transmission rod 13 drives the fixed ring 14 and the disc 16 to rotate, the fixed ring 14 drives the stirring blade 15 to rotate, the disc 16 drives the stirring rod 17 to rotate, under the action of the stirring blade 15 and the stirring rod 17, the materials are stirred and mixed, while stirring, the rotation of the shaft 7 drives the active gear 8 to rotate, the active gear 8 drives the driven gear 9 to rotate, the driven gear 9 drives the rotating rod 10 to rotate, the rotating rod 10 drives the inner tank 2 to rotate, so that the discharge port 18 and the discharge pipe 19 can rotate to the same position, when the discharge port 18 and the discharge pipe 19 are aligned, the material inside the inner tank 2 is discharged through the discharge pipe 19, The concrete material discharged through the discharge pipe 19 is transported to the upper part of the sieve plate 24, and the motor 21 is started. The output end of the motor 21 drives the rotating shaft 22 to rotate. The rotation of the rotating shaft 22 drives the cam 23 to rotate. The rotation of the cam 23 drives the sieve plate 24 to move up and down outside the limit column 25. When the sieve plate 24 moves, it squeezes the buffer spring 26. Under the elastic action of the buffer spring 26, the sieve plate 24 shakes up and down inside the screening bucket 28 to screen the concrete material. Finally, the screened concrete is discharged outwardly through the discharge pipe 27, thereby achieving effective screening of the concrete, separating impurities, large particles or particles that do not meet the requirements in the raw materials, improving the quality and purity of the aggregate in the concrete, and ensuring the uniformity and stability of the concrete.
