Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete production technology, specifically to a concrete production mixing device with anti-caking properties. Background Technology
[0002] Concrete is short for cement concrete. It mainly refers to artificial stone made by mixing cement, water, sand and gravel, adding chemical admixtures and mineral admixtures, and then uniformly mixing, compacting and molding and curing. The most important step is to mix it evenly.
[0003] As disclosed in CN221249349U, a concrete mixing device with anti-caking properties includes a tank body. A protective cover is provided at the top of the tank body. A motor is fixedly connected to the side surface of the protective cover. A rotating shaft is fixedly connected to the output end of the motor. A first gear is fixedly connected to the side surface of the rotating shaft. A second gear is meshed with the side surface of the first gear. A first rotating rod is fixedly connected to the lower surface of the second gear. The beneficial effects of this invention are as follows: By setting multiple gear combinations inside the protective cover, the first and second rotating rods rotate in the same direction but at different speeds; the third and fourth rotating rods rotate in the same direction but at different speeds. Furthermore, the rotation speeds of the first and fourth rotating rods, and the second and third rotating rods, are the same, but their directions are different. These different rotation speeds and directions increase the overall mixing effect of the concrete raw materials and improve work efficiency.
[0004] Although the aforementioned patent has a cleaning brush on the outside of the connecting rod, during the concrete mixing process, the cleaning brush is continuously subjected to the impact of aggregates, causing the nylon bristles to break rapidly. At the same time, the aggregates in the concrete cause severe wear on the bristles, and the highly alkaline cement slurry further corrodes the bristle material. More seriously, the freshly mixed concrete will continuously stick to the gaps between the bristles, which not only greatly reduces the cleaning efficiency but also causes the cleaning structure to completely fail in a short period of time. Therefore, the above-mentioned device cannot achieve the purpose of preventing clumping. Utility Model Content
[0005] The purpose of this invention is to provide a mixing device for concrete production with anti-caking properties, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] like Figure 1-4 As shown, this utility model provides a technical solution:
[0026] A concrete mixing device with anti-caking function includes a mixing drum 1, with a mixing mechanism located in the middle of its inner side. The mixing mechanism includes a mixing rod 3 rotatably connected to the middle of the mixing drum 1 via bearings, and a motor 4 vertically fixed to the middle of the top of the mixing drum 1. The output shaft of the motor 4 is coaxially fixed to the mixing rod 3 via a coupling. An agitator 5 is fixedly installed at the bottom end of the mixing rod 3. Scrapers 6 are fixedly installed on both sides of the bottom of the mixing rod 3, with the lower end face of the scrapers 6 slidingly contacting the inner bottom wall of the mixing drum 1. Vertical aggregate inlets 7 and water inlets 8 are respectively connected to the left and right sides of the top of the mixing drum 1. A cement inlet 9 is fixedly installed on the other side of the mixing drum 1 away from the aggregate inlets 7 and water inlets 8. A discharge port 18 is fixedly installed at the bottom right side of the mixing drum 1. A distribution plate 2 is located at the upper inner end of the mixing drum 1. A drive mechanism is provided between the distribution plate 2 and the mixing mechanism. The mechanism includes a gear 10 fixedly connected to the outside of the upper end of the stirring rod 3, and a gear 11 rotatably connected to the left side of the stirring rod 3 via a rotating shaft. The gear 11 meshes with the gear 10. A guide rail 12 is arranged circumferentially on the inner top wall of the mixing tank 1, and a gear ring 13 is movably installed on the inner ring of the guide rail 12. The teeth on the inner ring of the gear ring 13 mesh with the teeth on the outer side of the gear 11. A guide ring 14 matching the guide rail 12 is fixedly connected to the outer wall of the gear ring 13. The top of the distributing plate 2 is fixedly connected to the lower end face of the gear ring 13. A feeding hopper 15 is fixedly installed on one side bottom of the distributing plate 2. A feeding mechanism is provided on both sides of the upper end of the mixing tank 1. The feeding mechanism includes a hanging rod 16 vertically fixed to both sides of the middle of the inner top wall of the mixing tank 1, and a baffle 17 fixedly connected to the bottom of the hanging rod 16. The baffle 17 matches the inner wall of the distributing plate 2. The feeding mechanism cooperates with the distributing plate 2.
[0027] In this embodiment, the uniform dispersion of cement material is achieved through the rotation and spreading action of the distribution plate 2, which effectively solves the problem of local accumulation caused by concentrated material falling in the prior art. During the rotation of the distribution plate 2, the cement is evenly sprinkled into the mixing area through the sprinkling hopper 15, so that the cement and aggregate can fully contact and mix, fundamentally avoiding the clumping phenomenon caused by uneven distribution.
[0028] Furthermore, the reverse rotation design of the distribution plate 2 and the agitator 5, combined with the passive pushing action of the baffle 17, forms a highly efficient material conveying system, which solves the problem of clumping caused by material residue in the prior art. At the same time, the baffle 17 can completely push the residual cement away from the spreading hopper 15, and the dual action ensures the thoroughness of material conveying.
[0029] Working principle: The motor 4 drives the stirring rod 3 to rotate through the coupling, which in turn drives the agitator 5 to mix the concrete in the mixing tank 1. At the same time, the scraper 6 at the bottom of the stirring rod 3 rotates with the stirring rod 3 and slides in contact with the bottom wall of the mixing tank 1 to remove the deposited material. When the stirring rod 3 rotates, it drives the gear 10 on it to rotate. The gear 10 meshes with the gear 2 11, which drives the gear ring 13 to rotate along the guide rail 12. The gear ring 13 slides in the guide rail 12 through the guide ring 14 and drives the distribution plate 2 to rotate in the opposite direction to the stirring rod 3. Cement enters the mixing tank 1 through the cement inlet 9 and falls into the distribution plate. On the material tray 2, the aggregate enters directly into the lower area of the mixing tank 1 through the aggregate inlet 7. The rotation of the material distribution tray 2 causes the bottom sprinkling hopper 15 to evenly spread the cement. At the same time, the inner wall of the material distribution tray 2 interacts with the baffle 17, which passively pushes the cement in the material distribution tray 2 and completely pushes out the cement remaining in the sprinkling hopper 15. The water injected by the water inlet pipe 8 enters directly into the lower area of the mixing tank 1 and mixes thoroughly with the spread cement and the directly entered aggregate under the action of the agitator 5 to form a uniform concrete mixture. The mixed concrete is discharged through the discharge port 18.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
