Description

Technical Field

[0001] This application relates to the technical field of concrete mixers, and in particular to a high-efficiency concrete mixer. Background Technology

[0002] In the field of construction engineering, concrete mixing equipment is one of the core pieces of equipment for ensuring construction quality and efficiency. Its main function is to fully mix raw materials such as cement, sand, gravel, water, and admixtures according to a preset ratio to form a uniform and stable concrete mixture, providing the basic materials for subsequent pouring, molding, and other processes. Among them, the mixing mechanism, as the core working component of the concrete mixing equipment, directly determines the quality of concrete mixing due to its rational design.

[0003] Traditional concrete mixing equipment typically employs a single mixing rod or two parallel mixing rods. A drive unit rotates the mixing rods around a fixed axis, using the mixing blades on the rods to mix the raw materials inside the tank. However, because the movement trajectory of the mixing rods is relatively fixed, blind spots easily form inside the tank, especially in the central and corner areas. This makes it difficult for the raw materials to be fully agitated and mixed, leading to localized aggregate concentration or uneven cement paste distribution in the finished concrete. This severely affects key performance indicators such as strength and fluidity, thus posing potential risks to the quality and safety of construction projects. Utility Model Content To address the issue of uneven mixing in existing concrete mixers, this application provides a high-efficiency concrete mixer.

[0004] The high-efficiency concrete mixer provided in this application adopts the following technical solution: A high-efficiency concrete mixer includes a mixing tank, which comprises a tank body and an equipment support. The tank body is vertically mounted on the head of the equipment support and is fixedly connected to the equipment support. A tank cover is detachably mounted on the upper end face of the tank body, and a positioning seat is fixedly mounted on the lower end face of the tank cover. Two sets of mixing rods are mounted on both ends of the positioning seat, and the two sets of mixing rods are arranged crosswise and rotatably connected to the positioning seat. A bottom scraping component is also mounted at the center of the positioning seat and is rotatably connected to the positioning seat. A drive component is also mounted on the tank cover to drive the mixing rods and the bottom scraping component to rotate synchronously.

[0005] By adopting the above technical solution, the mixing tank is designed with a structure in which the tank body and equipment support cooperate, ensuring that the tank body can be stably fixed to the ground during use. A tank cover is installed on the upper surface of the tank body to cover the top of the tank and facilitate the positioning and installation of other components. By setting two sets of intersecting mixing rods and a bottom scraper assembly, driven synchronously by the drive assembly, the concrete in the tank can be mixed in multiple directions and angles, greatly improving the uniformity of mixing. The two sets of mixing rods can also be set to different speeds, facilitating differential mixing to achieve uniform shearing of the concrete. Furthermore, by installing the bottom scraper assembly at the center of the positioning seat, the drive assembly drives the two sets of mixing rods to rotate synchronously with the bottom scraper assembly, thereby agitating the sediment at the bottom of the tank and preventing sediment buildup.

[0006] Optionally, the tank body includes a stirring shell and a conical bottom shell. The conical bottom shell is installed on the lower end face of the stirring shell and is integrally formed with the stirring shell. A large-diameter discharge plate that can be flipped open is installed on the lower end face of the conical bottom shell. The large-diameter discharge plate is controlled to open and close by a hydraulic cylinder.

[0007] By adopting the above technical solution, the tank body uses an integrated structure of a mixing shell and a conical bottom shell, which facilitates the accumulation of concrete at the bottom under gravity. The large-diameter discharge plate is controlled by a hydraulic cylinder to open and close, enabling rapid and smooth discharge, improving discharge efficiency, reducing discharge time, and avoiding blockage problems during the discharge process.

[0008] Optionally, the equipment support includes a bottom ring seat, diagonal braces, and a top ring seat for fixing the mixing shell. The diagonal braces are symmetrically installed on both sides of the upper surface of the bottom ring seat, and the lower surface of the diagonal braces is fixedly connected to the bottom ring seat. The two sides of the top ring seat are fixed to the head of the diagonal braces.

[0009] By adopting the above technical solution, the equipment support frame uses a structural design of bottom ring seat, diagonal braces, and top ring seat, providing stable support for the tank. The diagonal braces enhance the stability and load-bearing capacity of the support frame, ensuring the smooth operation of the mixer, reducing vibration and shaking, and extending the service life of the equipment.

[0010] Optionally, the can lid is provided with side lugs on both sides that are connected to the equipment bracket, and a feed shell is also installed on the upper surface of the can lid. Both the side lugs and the feed shell are fixedly connected to the can lid.

[0011] By adopting the above technical solution, the side lugs on both sides of the tank cover can be easily connected to the equipment support, making the tank cover installation more secure. The design of the feed shell facilitates the addition of concrete raw materials into the tank, improving the convenience and efficiency of feeding.

[0012] Optionally, the positioning seat includes a bending seat block, a transverse plate, and an extension bending plate. The bending seat block is fixedly installed on the lower end face of the can lid, the transverse plate is fixedly installed on both ends of the bending seat block, and the extension bending plate is inclinedly installed on the outer end of the transverse plate, and the extension bending plate is integrally formed with the transverse plate.

[0013] By adopting the above technical solution, the structural design of the bent seat block, transverse plate, and extended bent plate of the positioning seat provides accurate installation positions and stable support for the stirring rod assembly and the bottom scraping assembly. The inclined installation of the extended bent plate allows the stirring rod assembly to stir at a suitable angle, further improving the stirring effect.

[0014] Optionally, the stirring rod assembly includes a central rotating rod, a sleeve, and stirring blades. The head of the central rotating rod is rotatably mounted on an extension curved plate, and a driven helical gear is fixedly mounted on the head of the central rotating rod. The sleeve is sleeved and fixed on the central rotating rod, and the stirring blades are evenly fixed on the outer surface of the sleeve.

[0015] By adopting the above technical solution, the structure of the central rotating rod, the sleeve section, and the mixing blades of the mixing rod assembly enables the mixing blades to mix the concrete as the central rotating rod rotates. The driven helical gear facilitates cooperation with the drive assembly to realize the rotation of the mixing rod assembly, and the mixing blades are evenly distributed on the sleeve section, which can fully mix the concrete in the tank.

[0016] Optionally, the scraping assembly includes a longitudinal rotating rod, a drive disk, and an oblique scraper. The head of the longitudinal rotating rod is rotatably mounted at the center of the bending block, the drive disk is fixedly mounted on the lower end face of the longitudinal rotating rod, and the oblique scraper is uniformly fixed on the lower end face of the drive disk.

[0017] By adopting the above technical solution, the structure of the longitudinal rotating rod, drive disc and oblique scraper of the bottom scraping component can scrape the concrete at the bottom of the tank through the oblique scraper during rotation, preventing the concrete from accumulating and clumping at the bottom, and ensuring the cleanliness of the bottom of the tank and the uniformity of mixing.

[0018] Optionally, the drive assembly includes a drive motor, double pulleys, a transmission belt, and a drive shaft. The drive motor is fixedly installed at the center of the upper surface of the can lid. The double pulleys are sleeved and fixed on the output shaft of the drive motor, and the lower end of the output shaft of the drive motor is fixed to the head of the longitudinal rotating rod through a coupling. The drive shaft is rotatably installed on the transverse plate, and a single pulley is fixedly installed on the head of the drive shaft. The single pulley is connected to the double pulleys through a transmission belt. A drive helical gear that meshes with the driven helical gear is also sleeved and fixed on the drive shaft.

[0019] By adopting the above technical solution, the drive assembly uses a structure of drive motor, double pulleys, transmission belt, and drive shaft, which enables synchronous rotation of the stirring rod assembly and the scraping assembly. After starting the drive motor, the double pulleys drive the transmission belts at both ends to rotate synchronously, thereby driving the scraping assembly at the lower end to rotate synchronously. The drive shaft is connected to the transmission belt via a single pulley, allowing the drive shaft to rotate via the transmission belt. In actual installation, different sizes of single pulleys can be selected to correspond with the double pulleys, thus achieving different speed ratios to meet different stirring requirements. When the drive shaft rotates, the meshing of the driven helical gear and the driving helical gear drives the stirring rod assembly to rotate and stir.

[0020] In summary, this application includes at least one of the following beneficial technical effects: By synchronously rotating two sets of intersecting mixing rods, this application achieves all-around mixing of concrete. Furthermore, the two sets of intersecting mixing rods can achieve differential rotation mixing, effectively avoiding the problem of uneven concrete mixing and improving concrete quality. The bottom scraping component ensures that the inclined scraper scrapes the concrete at the bottom of the tank during mixing, causing waterproof concrete to accumulate and clump at the bottom, further ensuring the cleanliness of the tank bottom and the uniformity of mixing. Moreover, the cooperation between the large-diameter discharge plate and the hydraulic cylinder makes the unloading process fast and smooth, reducing unloading time and improving construction efficiency.

The head of the equipment support 12 is vertically mounted on the tank body 11 and the tank body 11 is fixedly connected to the equipment support 12. A tank cover 2 is detachably mounted on the upper end face of the tank body 11. A positioning seat 3 is fixedly mounted on the lower end face of the tank cover 2. Two sets of mixing rods 4 are mounted on both ends of the positioning seat 3. The two sets of mixing rods 4 are arranged crosswise and are rotatably connected to the positioning seat 3. A bottom scraping component 5 is also mounted at the center of the positioning seat 3 and is rotatably connected to the positioning seat 3. A drive component 6 is also mounted on the tank cover 2 to drive the mixing rods 4 and the bottom scraping component 5 to rotate synchronously. By designing the mixing tank 1 with a structure in which the tank body 11 and the equipment support 12 cooperate, it is ensured that the tank body 11 can be stably fixed to the ground by the equipment support 12 during use. A tank cover 2 is installed on the upper surface of the tank body 11 to cover the upper part of the tank body 11 and facilitate the positioning and installation of other components. By setting two sets of intersecting mixing rods 4 and a bottom scraper assembly 5, which are driven synchronously by the drive assembly 6, the concrete inside the tank body 11 can be mixed in multiple directions and angles, greatly improving the uniformity of the mixing. The two sets of mixing rods 4 can also be set to different speeds to achieve uniform shearing of the concrete through differential mixing. Furthermore, by installing the bottom scraper assembly 5 at the center of the positioning seat 3, it is ensured that the drive assembly 6 drives the two sets of mixing rods to rotate synchronously with the bottom scraper assembly 5. This bottom scraper assembly 5 then stirs up the sediment at the bottom of the tank body 11, preventing sediment buildup.

[0030] Reference Figure 1and Figure 2 The tank body 11 includes a mixing shell 111 and a conical bottom shell 112. The conical bottom shell 112 is installed on the lower end face of the mixing shell 111 and is integrally formed with the mixing shell 111.

The equipment support 12 includes a bottom ring seat 121, diagonal braces 122, and a top ring seat 123 for fixed installation of the mixing shell 111. The diagonal braces 122 are symmetrically installed on both sides of the upper surface of the bottom ring seat 121, and their lower ends are fixedly connected to the bottom ring seat 121. The two sides of the top ring seat 123 are fixed to the heads of the diagonal braces 122. The equipment support 12, with its bottom ring seat 121, diagonal braces 122, and top ring seat 123, provides stable support for the tank 11. The diagonal braces 122 enhance the stability and load-bearing capacity of the support, ensuring the smooth operation of the mixer, reducing vibration and shaking, and extending the service life of the equipment.

The feed shell 22 facilitates the addition of concrete raw materials into the tank body 11, improving the convenience and efficiency of feeding.

[0032] Reference Figure 3 The positioning seat 3 includes a bent seat block 31, a transverse plate 32, and an extension bent plate 33. The bent seat block 31 is fixedly installed on the lower end face of the tank lid 2, the transverse plate 32 is fixedly installed on both ends of the bent seat block 31, and the extension bent plate 33 is inclinedly installed on the outer end of the transverse plate 32, and the extension bent plate 33 is integrally formed with the transverse plate 32. The structural design of the bent seat block 31, transverse plate 32, and extension bent plate 33 of the positioning seat 3 provides accurate installation positions and stable support for the stirring rod assembly 4 and the bottom scraping assembly 5. The inclined installation of the extension bent plate 33 allows the stirring rod assembly 4 to stir at a suitable angle, further improving the stirring effect.

[0033] Reference Figure 1 and Figure 4The mixing rod assembly 4 includes a central rotating rod 41, a sleeve 42, and mixing blades 43. The head of the central rotating rod 41 is rotatably mounted on an extension curved plate 33, and a driven helical gear 411 is fixedly mounted on the head of the central rotating rod 41. The sleeve 42 is sleeved and fixed on the central rotating rod 41, and the mixing blades 43 are evenly fixed on the outer surface of the sleeve 42. The structure of the central rotating rod 41, sleeve 42, and mixing blades 43 of the mixing rod assembly 4 allows the mixing blades 43 to mix the concrete as the central rotating rod 41 rotates. The driven helical gear 411 facilitates cooperation with the drive assembly 6 to realize the rotation of the mixing rod assembly 4. The evenly distributed mixing blades 43 on the sleeve 42 can fully mix the concrete in the tank 1.

[0034] Reference Figure 5 The bottom scraping assembly 5 includes a longitudinal rotating rod 51, a drive disc 52, and an inclined scraper 53.

The structure of the longitudinal rotating rod 51, drive disc 52, and inclined scraper 53 of the bottom scraping assembly 5 enables the inclined scraper 53 to scrape the concrete at the bottom of the tank 11 during rotation, preventing the concrete from accumulating and clumping at the bottom, thus ensuring the cleanliness of the bottom of the tank 11 and the uniformity of mixing.

[0035] Reference Figure 4 and Figure 5The drive assembly 6 includes a drive motor 61, double pulleys 62, a transmission belt 63, and a drive shaft 64. The drive motor 61 is fixedly mounted at the center of the upper surface of the tank cover 2. The double pulleys 62 are sleeved and fixed on the output shaft of the drive motor 61, and the lower end of the output shaft of the drive motor 61 is fixed to the head of the longitudinal rotating rod 51 through a coupling. The drive shaft 64 is rotatably mounted on the transverse plate 32, and a single pulley 641 is fixedly mounted on the head of the drive shaft 64. The single pulley 641 is connected to the double pulleys 62 through the transmission belt 63. A drive helical gear 642 that meshes with the driven helical gear 411 is also sleeved and fixed on the drive shaft 64. By adopting the above technical solution, the drive assembly 6, with its structure of drive motor 61, double pulleys 62, transmission belt 63, and drive shaft 64, can achieve synchronous rotation of the stirring rod assembly 4 and the bottom scraping assembly 5. After the drive motor 61 is started, the double pulleys 62 drive the transmission belts 63 at both ends to rotate synchronously, which in turn drives the scraping assembly 5 at the lower end to rotate synchronously. The drive shaft 64 is connected to the transmission belts 63 via a single pulley 641. This allows the drive shaft 64 to rotate via the transmission belts 63. In actual installation, different sizes of single pulleys 641 can be selected to correspond with the double pulleys 62, thereby achieving different speed ratios to meet different stirring needs. When the drive shaft 64 rotates, the meshing of the driven helical gear 411 and the drive helical gear 642 drives the stirring rod assembly 4 to rotate and stir. The belt drive provides smooth transmission, low noise, and allows for adjustment of the transmission ratio as needed, ensuring effective stirring and scraping.

[0036] The implementation principle of a high-efficiency concrete mixer according to this application embodiment is as follows: In actual use, the drive motor 61 is started, and the output shaft of the drive motor 61 drives the double pulley 62 to rotate. The double pulley 62 drives the single pulley 641 to rotate through the transmission belt 63, thereby causing the drive shaft 64 to rotate. The drive helical gear 642 on the drive shaft 64 meshes with the driven helical gear 411, driving the central rotating rod 41 of the mixing rod assembly 4 to rotate, and the mixing blades 43 mix the concrete in the tank. At the same time, the output shaft of the drive motor 61 drives the longitudinal rotating rod 51 to rotate through the coupling, causing the drive disc 52 and the inclined scraper 53 of the bottom scraping assembly 5 to rotate, scraping the concrete at the bottom of the tank. Concrete raw materials are added into the tank through the feed shell 22 for mixing. After mixing is completed, the hydraulic cylinder is controlled to open the large-diameter discharge plate, and the concrete is discharged quickly and smoothly through the large-diameter discharge plate under the action of gravity.
