Abstract
Description
Technical Field
[0001] The invention relates to the technical field of concrete mixing, and in particular to a high-efficiency concrete mixing device. Background Art
[0002] Concrete is an important building material widely used in modern buildings. Concrete is a man-made material, generally made of cement, sand (fine aggregate), gravel (coarse aggregate) and water in a certain proportion. In order to improve certain properties of concrete, appropriate admixtures and admixtures are often added. Therefore, concrete is mainly composed of six components: cement, water, coarse aggregate (mainly gravel), fine aggregate (mainly sand), mineral admixtures (mainly fly ash or other admixtures), and admixtures (such as expansion agents, water reducers, retarders, etc.). Concrete has a certain fluidity before hardening, which is convenient for construction operations. After hardening, concrete has properties such as pressure resistance, water resistance, and fire resistance. The cement in concrete reacts chemically with water, and stirring accelerates the reaction to form cement slurry, which wraps around the surface of the aggregate and fills its voids. This hardening process makes the concrete a whole with excellent mechanical properties.
[0003] In the existing concrete mixing technology, the mixing tank is usually driven directly by a driving assembly, and the mixing is performed by blades staggered inside the mixing tank and arranged on the inner wall of the mixing tank; this method not only takes a long time to mix and has low efficiency, but is also not conducive to cleaning the cement attached to the inner wall of the mixing tank, resulting in cement waste and increased costs. At the same time, when the cement remaining on the inner wall of the mixing tank solidifies, a layer of hardened sediment will form on the inner wall of the mixing tank. This layer of sediment will hinder the normal mixing of concrete in the tank body, resulting in a decrease in the homogeneity of the concrete. Concrete homogeneity is one of the important indicators of concrete quality. Concrete with poor homogeneity is prone to problems such as uneven strength and structural defects after pouring and hardening. In summary, the present invention proposes a high-efficiency concrete mixing device, which improves the mixing efficiency under the premise of sufficient mixing, and promptly cleans the concrete attached to the inner wall of the tank body during mixing, thereby improving the quality of the final product. Summary of the invention
[0004] In order to solve the above problems, the present invention provides a high-efficiency concrete mixing device, which improves the mixing efficiency under the premise of sufficient mixing, and timely cleans the concrete attached to the inner wall of the tank during the mixing process, thereby improving the quality of the final product.
[0005] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a high-efficiency concrete mixing device comprises a mixing tank, wherein the interior of the mixing tank is divided into a conversion chamber and a mixing chamber from right to left, a support assembly for supporting the mixing tank is slidably connected to the bottom of the mixing tank, a driving assembly is arranged on the top of the supporting assembly, and a movable disk which cooperates with the mixing tank to rotate is embedded in one end of the mixing tank close to the driving assembly;
[0006] The driving component is fixedly connected to a first gear and a second gear located inside the first gear at one end close to the mixing tank, the first gear is an internal gear, the first gear is meshed with a plurality of third gears, the third gears are all meshed with the second gear, the first gear, the second gear and the plurality of third gears are all meshed with each other to form a planetary gear structure, the first gear is fixedly connected to the mixing tank at a side away from the driving component, the third gear is coaxially fixedly connected to a first rotating column at a side close to the mixing tank, the first rotating column extends through the mixing tank into the mixing chamber at one end away from the third gear and is fixedly connected to a plurality of scrapers, the plurality of scrapers are all able to contact the inner wall of the mixing chamber, and the second gear is coaxially fixedly connected to a mixing component for mixing concrete at one end close to the mixing tank;
[0007] The stirring tank and the movable disk are in rotational cooperation, the stirring tank and the first rotating column are in sliding cooperation, the stirring assembly and the movable disk are in rotational cooperation; the stirring assembly and the stirring tank are in sliding cooperation;
[0008] The inner wall of the conversion chamber is fixedly connected with a conversion component for causing the stirring component to rotate and slide horizontally at the same time.
[0009] Principle of the basic solution: Through the planetary structure composed of the first gear, the second gear and several third gears, the mixing tank is rotated under the drive of the rotating motor, and the first rotating rod is driven to rotate, thereby driving the scraper on its surface to continuously scrape the concrete on the inner wall of the mixing tank; at the same time, the rotation of the second gear drives the mixing component to move, so that the mixing blades can fully mix the concrete inside the tank, and the conversion component can make the mixing component move horizontally while rotating, so as to further improve the mixing efficiency.
[0010] The above scheme has the following beneficial effects:
[0011] 1. Compared with the prior art, in which concrete is stirred directly by rotating the mixing tank, the present invention realizes the synchronous movement of the rotation of the mixing tank and the mixing assembly and the scraper through the design of the planetary gear structure, which not only allows the concrete to be stirred in all directions in the mixing chamber, but also continuously scrapes off the residual concrete on the inner wall of the mixing tank through the scraper, avoiding the accumulation and waste of concrete, and significantly improving the mixing efficiency and uniformity. Due to the rotation of the mixing tank and the synchronous movement of the mixing assembly, the concrete is fully stirred in the mixing chamber, and the concrete can be effectively mixed, thereby avoiding the mixing dead angle and uneven distribution of concrete. At the same time, the planetary gear structure can efficiently transmit power, so that under the same mixing effect, the required driving force is relatively small, thereby reducing energy consumption. In addition, due to the sliding fit design of the mixing tank and the mixing assembly, the friction and wear between the moving parts are reduced, further extending the service life of the equipment and reducing maintenance costs.
[0012] 2. In this solution, the mixing component can achieve horizontal sliding by transforming the components while mixing. This composite motion mode can more effectively break up the agglomerates in the concrete and promote uniform mixing between the components, thereby improving the quality and performance of the concrete. Some components in the concrete (such as cement particles) may be aggregated together due to electrostatic effects or physical adsorption. The composite motion mode can more effectively break up these agglomerates through the rotation and horizontal sliding of the mixing component, so that the components are more evenly dispersed in the concrete. The composite motion mode can not only break up the agglomerates, but also promote the interaction and mixing between the components through the rotation and horizontal sliding of the mixing component, making the mixing process more sufficient and uniform, which helps to improve the strength and durability of the concrete. At the same time, by adjusting the rotation speed and horizontal sliding amplitude of the mixing component, it can adapt to the mixing needs of concrete with different proportions and performances.
[0013] At the same time, the rotational coordination and sliding coordination between the stirring rod and the stirring tank, as well as the rotational coordination between the first rotating column and the second rotating column and the stirring tank and the movable disk, make the entire stirring device more flexible and adaptable during operation, reduce friction and wear between components, and extend the service life of the equipment.
[0014] Furthermore, the support assembly includes a base, and a plurality of support seats are arranged on the top of the base, and the tops of the support seats are all slidably connected to the surface of the mixing tank.
[0015] Beneficial effects: The base, as the foundation of the entire stirring device, can provide stable support. Through the sliding connection between several support seats and the surface of the stirring tank, the stirring tank can be rotated while ensuring that the stirring tank remains horizontal and stable during the stirring process, avoiding uneven stirring or equipment damage caused by shaking or tilting. The design of the sliding connection allows the relative position between the support seat and the stirring tank to be flexibly adjusted. This not only meets the fine-tuning of the position of the stirring tank under different stirring requirements, but also facilitates the daily maintenance and overhaul of the equipment. For example, when the stirring tank needs to be cleaned or parts need to be replaced, the stirring tank can be easily moved to improve work efficiency.
[0016] Furthermore, the driving assembly includes a motor seat arranged on the top of the base and a positioning plate fixedly connected to the motor seat near one end of the stirring tank. A rotating motor is provided inside the motor seat. The output shaft of the rotating motor passes through the positioning plate and is coaxially fixedly connected to the second gear. The output shaft of the rotating motor is rotatably connected to the positioning plate, and the third gear is rotatably connected to the positioning plate on the side away from the stirring tank.
[0017] Beneficial effects: The design of the motor base and the positioning plate makes the entire drive assembly compact and stable. The positioning plate not only provides rotation support for the third gear, but also enhances the connection stability between the drive assembly and the mixing tank, ensuring that there will be no shaking or deviation during the mixing process. The output shaft of the rotating motor is directly coaxially fixed to the second gear, reducing energy loss during power transmission, so that the mixing device can obtain more stable and efficient mixing power. The driving assembly can stably and efficiently transmit power, so the mixing device can maintain the optimal mixing speed and strength during the mixing process. This helps to ensure that the concrete is fully mixed and evenly distributed in the mixing chamber, thereby improving the mixing effect and quality.
[0018] Furthermore, the stirring assembly includes a second rotating column coaxially fixedly connected to the second gear near one end of the stirring tank, the second rotating column near one end of the stirring tank extends through the stirring tank into the stirring chamber and is coaxially slidably connected with a stirring rod, a support plate slidingly matched with the stirring rod is provided in the stirring chamber, the support plate slidingly matches with the stirring chamber, the stirring rod extends through the stirring tank into the conversion chamber away from one end of the second rotating column, the stirring rod is fixedly connected along its axial direction with a stirring blade located in the stirring chamber, and the stirring blade is a spiral blade; the first rotating column is rotatably matched with the support plate.
[0019] Beneficial effects: The sliding and rotating design of the mixing assembly enables the mixing rod and mixing blades to better adapt to the changes of concrete in the mixing chamber, thereby improving the mixing efficiency. The sliding and rotating design reduces the friction and wear of the equipment during operation and extends the service life of the equipment. The flexibility and adaptability of the mixing assembly enable the equipment to better adapt to the mixing needs of concrete of different types and specifications, thereby improving the durability and reliability of the equipment. The design of the spiral blade enables it to generate strong shear and extrusion forces during rotation, which can more effectively mix and mix the concrete. This multi-dimensional mixing method ensures that the concrete reaches a highly uniform state in a short time, thereby improving the mixing efficiency. The rotation of the spiral blade not only pushes the concrete from one end to the other, but also divides, folds and recombine the concrete through the interaction between the blades, forming a complex material flow pattern. This flow pattern helps to break up the agglomerates in the concrete and make the cement particles more evenly distributed in the aggregate, thereby enhancing the mixing effect.
[0020] Furthermore, a feed port communicating with the stirring chamber is provided on the top of the stirring tank.
[0021] Beneficial effects: The feed port is located at the top of the mixing tank, so that the operator can easily put the raw materials of concrete (such as cement, aggregate, water, etc.) into the mixing tank. This design simplifies the operation process and improves work efficiency. The materials added through the top feed port can be distributed more evenly in the mixing tank, which helps to reduce the accumulation and agglomeration of materials during the mixing process and improve the uniformity and quality of mixing.
[0022] Furthermore, a discharge port communicating with the stirring chamber is provided at the bottom of the stirring tank.
[0023] Beneficial effects: The discharge port is located at the bottom of the mixing tank, which ensures that the concrete can be discharged smoothly from the mixing tank after mixing, reducing the residue and accumulation of materials in the mixing tank, and improving the discharge efficiency and accuracy of the equipment. The design of the bottom discharge port helps to reduce the dead corner area during the mixing process. Since the concrete will be pushed and sheared by the mixing blades during mixing, the bottom discharge can ensure that these forces can act evenly on the materials in the entire mixing area, thereby avoiding the formation of difficult-to-discharge accumulation of materials at the bottom of the mixing tank.
[0024] Furthermore, the diameter of the second rotating column is smaller than the diameter of the stirring rod.
[0025] Beneficial effect: The diameter of the second rotating column is smaller than that of the stirring rod, which ensures that the stirring rod can slide along the second rotating column, thereby improving the stirring efficiency.
[0026] Furthermore, the transformation assembly includes a transformation rod fixedly connected to the inner wall of the transformation chamber, a guide ball is fixedly connected to one end of the transformation rod away from the inner wall of the transformation chamber, the part of the stirring rod located in the transformation chamber is coaxially fixedly connected to a cylindrical cam, the guide ball is located in the groove of the cylindrical cam, and the diameter of the stirring rod is smaller than the diameter of the cylindrical cam.
[0027] Beneficial effect: When the diameter of the stirring rod is small, the resistance of the concrete to the stirring rod during the mixing process can be reduced, which helps to increase the rotation speed and mixing intensity of the stirring blades, making it easier for the concrete to flow and mix in the mixing area, thereby improving the mixing efficiency. At the same time, the diameter of the stirring rod is smaller than the diameter of the cylindrical cam, so that when the cylindrical cam rotates, the force of the horizontal movement of the guided ball limiter is sufficient to move the stirring rod horizontally, thereby accelerating the mixing rate through the back-and-forth horizontal movement of the stirring rod.
[0028] Furthermore, the diameter of the third gear is smaller than the diameter of the second gear.
[0029] Beneficial effect: The design that the diameter of the third gear is smaller than that of the second gear helps to reduce the volume and weight of the entire transmission system while maintaining sufficient torque transmission capacity to ensure that the stirring rod and the first rotating shaft have sufficient torque.
[0030] Furthermore, sealing rings are provided at the connection points between the stirring rod and the first rotating rod and the stirring tank.
[0031] Beneficial effect: The setting of the sealing ring significantly enhances the sealing performance of the connection between the stirring rod and the first rotating rod and the mixing tank. Since a certain mixing uniformity needs to be maintained during the concrete mixing process, the close fit of the sealing ring can effectively prevent material leakage and ensure that the material will not overflow from the connection during the mixing process, thereby maintaining the amount of material inside the mixing tank. Good sealing performance can also improve the mixing efficiency. If there is a leak at the connection, the material may flow out from the leak, resulting in a reduction in the amount of material inside the mixing tank, thereby affecting the mixing efficiency. The setting of the sealing ring can ensure the stability of the material during the mixing process, improve the mixing efficiency, and ensure the quality and uniformity of the concrete.

[0041] The following is further described in detail through specific implementation methods:
[0042] Example:
[0043] As attached Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown: a high-efficiency concrete mixing device, including a mixing tank 1, the interior of the mixing tank 1 is divided into a conversion chamber and a mixing chamber from right to left, a feeding port 4 connected to the mixing chamber is opened on the top of the mixing tank 1, and a discharge port 19 connected to the mixing chamber is opened at the bottom of the mixing tank 1; a supporting assembly for supporting the mixing tank 1 is slidably connected to the bottom of the mixing tank 1 through a roller, a driving assembly is provided on the top of the supporting assembly, and a movable disk 6 that rotates with the mixing tank 1 is embedded in one end of the mixing tank 1 close to the driving assembly.
[0044] The driving assembly is fixedly connected to the first gear 7 and the second gear 13 located inside the first gear 7 at one end near the mixing tank 1. The first gear 7 is an internal gear. The first gear 7 is meshed with a plurality of third gears 8. The third gears 8 are all meshed with the second gear 13. The first gear 7, the second gear 13 and the plurality of third gears 8 are all meshed with each other and form a planetary gear structure. The diameter of the third gear 8 is smaller than the diameter of the second gear 13. The right side of the first gear 7 is welded to the mixing tank 1. The right side of the third gear 8 is coaxially bolted with the first rotating column 3. The right end of the first rotating column 3 passes through the mixing tank 1 and extends into the mixing chamber and is fixedly connected with a plurality of scrapers 2. The plurality of scrapers 2 can contact the inner wall of the mixing chamber. The right side of the second gear 13 is coaxially screwed with a mixing assembly for mixing concrete. The mixing tank 1 and the movable disk 6 are rotationally matched, the mixing tank 1 and the first rotating column 3 are slidingly matched, the mixing assembly and the movable disk 6 are rotationally matched; the mixing assembly and the mixing tank 1 are slidingly matched.
[0045] The inner wall of the conversion chamber is fixedly connected with a conversion component for causing the stirring component to rotate and slide horizontally at the same time.
[0046] The stirring assembly includes a second rotating column 14 connected to the right side of the second gear 13 by a coaxial screw. The right end of the second rotating column 14 extends through the stirring tank 1 into the stirring chamber and is coaxially slidably connected with a stirring rod 16. Preferably, the sliding match between the slide groove and the slider ensures that the stirring rod 16 can coaxially rotate with the second rotating column 14 and can also slide along the axis direction of the second rotating column 14. A support plate 21 that rotates with the stirring rod is embedded in the stirring chamber, and the support plate 21 slides with the stirring chamber; the first rotating column 3 rotates with the support plate 21, so as to support the stirring rod 16 while avoiding the collision between the support plate 21 and the first rotating column 3 when the stirring tank 1 rotates; the diameter of the second rotating column 14 is smaller than that of the stirring rod 16, and the right end of the stirring rod 16 extends through the stirring tank 1 into the conversion chamber. The stirring rod 16 is welded with a stirring blade 17 located in the stirring chamber along its axial direction, and the stirring blade 17 is a spiral blade. The connection between the stirring rod 16 and the first rotating rod and the stirring tank 1 is embedded with a sealing ring.
[0047] The transformation assembly includes a transformation rod 5 welded to the inner wall of the transformation chamber, a guide ball 20 is welded to the lower end of the transformation rod 5, the part of the stirring rod 16 located in the transformation chamber is coaxially integrally formed with a cylindrical cam 15, the guide ball 20 is located in the groove of the cylindrical cam 15, and the diameter of the stirring rod 16 is smaller than the diameter of the cylindrical cam 15.
[0048] The supporting assembly includes a base 12 , and a plurality of supporting seats 18 are bolted to the top of the base 12 , and the tops of the supporting seats 18 are all slidably connected to the surface of the mixing tank 1 .
[0049] The driving assembly includes a motor seat 9 integrally formed on the top of the base 12 and a positioning plate 11 bolted to the right side of the motor seat 9. A rotating motor 10 is bolted inside the motor seat 9. The output shaft of the rotating motor 10 passes through the positioning plate 11 and is coaxially bolted and fixed to the second gear 13. The output shaft of the rotating motor 10 rotates in coordination with the positioning plate 11, and the left side of the third gear 8 is rotationally connected to the positioning plate 11.
[0050] At the same time, in order to ensure that the rotation of the mixing tank 1 does not affect the rotation of the first rotating column 3, the second rotating column 14 and the mixing rod 16 at the same position, the matching mode of the movable disk 6 and the support plate 21 with the mixing tank 1 is preferably a matching mode of a slider groove.
[0051] The specific implementation process is as follows: first, the concrete raw material is put into the mixing chamber inside the mixing tank 1 from the feed port 4, and then the feed port 4 and the discharge port 19 are closed, and the rotating motor 10 is started. The motor output shaft drives the second gear 13 to rotate. Due to the existence of the planetary gear structure (the first gear 7, the second gear 13 and a plurality of third gears 8), the third gear 8 and the first gear 7 will also rotate accordingly. At the same time, according to the corresponding gear ratio, a differential rotation is formed, so that the speed of the second gear 13 is less than the third gear 8 and greater than the first gear 7. When the third gear 8 rotates, the scraper 2 is driven to rotate in the mixing chamber through the first rotating column 3 to scrape off the concrete attached to the inner wall of the mixing tank 1. At the same time, when the second gear 13 rotates, the stirring rod 16 is driven to rotate in the conversion chamber and the mixing chamber through the second rotating column 14, and the concrete is stirred in the mixing chamber through the stirring blade 17 (spiral blade) on the stirring rod 16. At the same time, since the positions of the third gear 8 and the second gear 13 are fixed, and since the outside of the mixing tank 1 is slidably connected to the support seat 18, when the second gear 13 rotates, the first gear 7 rotates, and then drives the mixing tank 1 to rotate with the first gear 7, completing the rotation of the mixing tank 1, which is helpful for the subsequent mixing of concrete. At the same time, due to the presence of the movable disk 6 and the support plate 21, when the mixing tank 1 rotates, the first rotating rod and the stirring rod 16 can be stably rotated in the original position without interfering with each other. At the same time, since the rotation speed of the mixing tank 1 is less than the rotation speed of the stirring rod 16, the guide ball 20 in the conversion chamber fixed in the conversion chamber by the conversion rod 5 can slide along the groove of the cylindrical cam 15 accordingly, thereby generating a lateral force on the stirring rod 16, and the connection between the stirring rod 16 and the second rotating column 14 and the mixing tank 1 can slide relatively. Therefore, as the stirring rod 16 rotates, the cylindrical cam 15 will drive the guide ball 20 to move along its groove, thereby realizing a certain form of conversion action (such as changing the flow direction of concrete, increasing the stirring effect, etc.) through the conversion rod 5, so that the stirring rod 16 performs a lateral reciprocating motion while rotating, thereby fully mixing and mixing the concrete raw materials inside the mixing tank 1. Finally, after the mixing is completed, the discharge port 19 is opened, and the mixed concrete is taken out for use.
[0052] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
