Description

Technical Field

[0001] This utility model relates to the field of concrete mixing, and more specifically, to a high-efficiency mixing device for commercial concrete. Background Technology

[0002] Concrete mixing is an operation method that mixes and stirs materials such as cement, lime, and water until they are uniform. There are two types of concrete mixing: manual mixing and mechanical mixing. Concrete mixing is widely used in construction projects in my country's industry, agriculture, transportation, national defense, water conservancy, and municipal engineering, and the demand is constantly increasing.

[0003] A search revealed that Chinese patent CN222958906U, in the prior art, discloses a "high-efficiency mixing device for commercial concrete," which includes a mixing drum. A rotating block is rotatably mounted on the inner top wall of the mixing drum, and two sets of external mixing blades are mounted on the outer wall below the rotating block. The rotating block drives the external mixing blades to rotate, which in turn mixes the concrete. After the concrete is mixed and then added to the mixing drum, the external mixing blades continue to strike the vibrating blades as they rotate. The vibrating blades can dissipate force as the rotating rod rotates. The mixing mechanism generally does not rotate too fast, thus the striking force is not too great, allowing the external mixing blades to vibrate without damaging them. An air hammer can strike the impact block, causing the inner wall of the mixing drum to vibrate, causing concrete on the external mixing blades and the inner wall of the mixing drum to fall, effectively preventing concrete accumulation on the inner wall of the mixing drum and ensuring better mixing of the concrete within the mixing drum's internal space. However, the following drawbacks still exist: (1) It is easy to form a mixing dead zone, especially the material near the cylinder wall and bottom area is difficult to mix fully, resulting in poor concrete uniformity.

[0004] (2) The inability to clean in time after mixing results in the accumulation of material residue inside the mixing drum, which in turn forms hard-to-handle clumps, interfering with the normal mixing process of the material inside the mixing drum and seriously affecting the service life of the equipment.

[0005] Therefore, a high-efficiency mixing device for commercial concrete is proposed. Utility Model Content

[0006] The purpose of this invention is to address the problem that existing mixing devices are prone to forming dead zones, especially in the areas near the cylinder wall and bottom, where materials are difficult to mix fully, resulting in poor concrete uniformity. This invention provides a high-efficiency mixing device for commercial concrete to solve the problems mentioned in the background art.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution: The present invention is as follows: a high-efficiency mixing device for commercial concrete, including a mounting base, a mixing drum being disposed through the mounting base, a mixing component for mixing concrete being fixedly installed on the top of the mixing drum, a cleaning component being fixedly installed on one side of the mounting base, and a feeding component being disposed through the mixing drum.

[0019] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0020] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0021] like Figures 1-5 As shown, this embodiment proposes a high-efficiency mixing device for commercial concrete, including a mounting base 1, a mixing tank 2 is installed through the mounting base 1, a mixing component 3 for mixing concrete is fixedly installed on the top of the mixing tank 2, a cleaning component 4 is fixedly installed on one side of the mounting base 1, and a feeding component 5 is installed through the mixing tank 2. The mixing assembly 3 includes a first motor 301 fixedly mounted to the top of the mixing tank 2. A screw 302 is mounted on the output end of the first motor 301. A sleeve 303 is fixedly mounted on the screw 302. Scraper rods 304 are provided on the outer side of the sleeve 303. There are three sets of scraper rods 304, and each scraper rod 304 is equipped with a stirring rod 305. When the first motor 301 is started, the screw 302 is driven to rotate. When the screw 302 rotates, it drives the scraper rods 304 fixed on the outer side of the sleeve 303 to rotate synchronously. During the rotation, the scraper rods 304 strongly scrape the concrete adhering to the inner wall of the mixing tank 2, causing the concrete to detach from the tank wall. At the same time, the stirring rods 305 equipped on the scraper rods 304 also rotate, thoroughly mixing the concrete in the mixing tank 2. The scraped concrete is then re-integrated into the mixing under the action of the stirring rods 305 to achieve uniform mixing.

[0022] like Figures 1-4 and Figure 6As shown, the cleaning component 4 includes a base 401 fixedly connected to one side of the mounting base 1 by bolts. A water storage tank 402 is fixedly installed on the top of the base 401, and a water pump 403 is fixedly installed on the top of the water storage tank 402. A water pump pipe 404 is provided through the top of the water storage tank 402 at one end of the water pump 403, and a water inlet pipe 405 is connected to the other end of the water pump 403. The other end of the water inlet pipe 405 passes through the top of the mixing tank 2. When cleaning is required, the water pump 403 is started to draw clean water from the water storage tank 402 through the water pump pipe 404, and the drawn clean water is transported to the inside of the mixing tank 2 through the water inlet pipe 405. The water, together with the scraper bar 304, scrapes the inner wall of the mixing tank 2 to achieve efficient cleaning of the inner wall and residues of the mixing tank 2. If water needs to be added during the mixing operation, this water supply method can also be used, which effectively reduces the labor intensity of manual cleaning and significantly improves the cleaning efficiency.

[0023] like Figures 1-4 As shown, the feeding assembly 5 includes a feed inlet 501 that penetrates the mixing tank 2. A second motor 502 is fixedly installed on one side of the feed inlet 501. A rotating shaft 503 is installed at the output end of the second motor 502, and a mixing rod 504 is provided on the rotating shaft 503. When the second motor 502 is started, it drives the rotating shaft 503 to rotate, and the mixing rod 504 on the rotating shaft 503 rotates accordingly. This premixes the concrete raw materials that enter the mixing tank 2 through the feed inlet 501, so that the raw materials are initially mixed evenly before entering the mixing tank 2. This improves the uniformity of the concrete raw materials, reduces the mixing time and energy consumption in the mixing tank 2, and improves the overall mixing efficiency.

[0024] like Figures 1-5 As shown, a spiral blade 3051 is fixedly installed on the screw 302. The spiral blade 3051 is located inside the scraper rod 304, and one side of the scraper rod 304 is in contact with the inner wall of the mixing tank 2. When the screw 302 rotates, it drives the spiral blade 3051 to rotate as well. During the mixing process, the spiral blade 3051 breaks up the lumps of concrete. The broken material is pushed upward along the spiral axis by the spiral blade 3051, conveying the material at the bottom of the mixing tank 2 to the top to re-participate in the mixing, forming a material circulation, further eliminating mixing dead zones and improving the uniformity of mixing.

[0025] like Figures 1-4 and Figure 6 As shown, a water inlet 4051 is provided through the water storage tank 402. The top of the water storage tank 402 is fixed to the bottom of the water pump 403 by bolts. The water storage tank 402 is located on one side of the mixing tank 2. Clean water is injected into the water storage tank 402 through the water inlet 4051, thereby fully meeting the water needs of the concrete mixing operation and subsequent equipment cleaning.

[0026] like Figure 3 and Figure 4 As shown, the mixing rods 504 are located inside the feed inlet 501, and three sets of mixing rods 504 are evenly distributed on the outside of the rotating shaft 503 by bolts. When the rotating shaft 503 rotates, it performs preliminary mixing of the concrete raw materials in the feed inlet 501, improving the uniformity of the raw materials. The multiple sets of mixing rods 504 increase the mixing coverage area and improve the mixing uniformity of the raw materials.

[0027] like Figures 1-4 and Figure 6 As shown, a discharge pipe 6 is installed through the bottom of the mixing tank 2, and a control valve 7 is installed on the discharge pipe 6. A discharge trough 8 is fixedly installed on the bottom of the base 401, and the other end of the discharge pipe 6 is connected to one side of the discharge trough 8. After mixing is completed, the control valve 7 on the discharge pipe 6 is opened, and the mixed concrete flows into the discharge trough 8 through the discharge pipe 6 and then is discharged from the discharge trough 8. The control valve 7 can adjust the discharge speed as needed; the discharge trough 8 makes the concrete discharge more concentrated, which is convenient for collection and transportation.

[0028] Specifically, when using this high-efficiency concrete mixing device: Material is poured into the inlet 501. The second motor 502 starts, driving the rotating shaft 503 to rotate. The mixing rod 504 on the rotating shaft 503 rotates accordingly, pre-mixing the concrete raw materials entering the mixing drum 2 through the inlet 501. This ensures the raw materials are initially and evenly mixed before entering the mixing drum 2, improving the uniformity of the concrete raw materials. The first motor 301 starts, driving the screw 302 to rotate. When the screw 302 rotates, it drives the scraper rod 304 fixed to the outside of the sleeve 303 to rotate synchronously. During rotation, the scraper rod 304 forcefully scrapes the concrete adhering to the inner wall of the mixing drum 2, causing the concrete to detach from the drum wall. Simultaneously, the mixing rod 305 equipped on the scraper rod 304 also rotates, thoroughly mixing the concrete inside the mixing drum 2. The scraped-off concrete is then... Under the action of the stirring rod 305, the mixture is stirred again to achieve uniform mixing. When the screw 302 rotates, it drives the spiral blade 3051 to rotate as well. During the stirring process, the spiral blade 3051 breaks up the lumps of concrete. The broken material is pushed by the spiral blade 3051 and moves upward along the spiral axis, transporting the material at the bottom of the mixing tank 2 to the top to participate in the stirring again, forming a material circulation and further eliminating the dead corners of the stirring. When cleaning is required, the water pump 403 is started to draw clean water from the water storage tank 402 through the water pipe 404. The drawn clean water is transported to the inside of the mixing tank 2 through the water inlet pipe 405. The scraper rod 304 scrapes the inner wall of the mixing tank 2 to achieve efficient cleaning of the inner wall and residues of the mixing tank 2. If water needs to be added during the stirring process, this water supply method can also be used, which effectively reduces the labor intensity of manual cleaning.

[0029] All technical features in this embodiment can be freely combined according to actual needs.

[0030] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
