Technical Field

[0001] This application relates to the field of mixing equipment technology, and in particular to a mixing equipment for processing high-strength crack-resistant concrete. Background Technology

[0002] High-strength crack-resistant concrete is a type of concrete with high strength and crack resistance. It is typically composed of high-strength cement, fine aggregate, coarse aggregate, and additives, effectively resisting the initiation and propagation of cracks. It is widely used in engineering structures that need to withstand large loads and harsh environments. The connection between high-strength crack-resistant concrete and the mixing plant lies in the fact that the mixing plant is responsible for accurately proportioning and mixing various materials during the production process, ensuring that the concrete meets design requirements in terms of strength and crack resistance. Using a mixing plant for high-strength crack-resistant concrete processing can improve the quality and stability of the concrete, reduce errors during production, and ensure the long-term durability and crack resistance of the final product, thereby enhancing the safety and reliability of the structure. A search revealed Chinese Patent Publication No. CN222345931U, which discloses a mixing device for processing high-strength crack-resistant concrete. The device includes a mixing tank and a support plate positioned directly above it. A support ring is rotatably connected to the lower end of the support plate. Multiple annularly distributed support rods are fixedly connected between the lower end of the support ring and the upper end of the mixing tank. A support block is fixedly connected to the inner wall of the support ring, and a servo motor is fixedly connected to the upper end of the support block. An annularly arranged groove is provided at the lower end of the support plate, and an annularly arranged rack is fixedly connected to the inner wall of the groove. A gear meshing with the rack is located within the groove. The output shaft of the servo motor extends upward through the support ring and is fixedly connected to the lower end of the gear. A circular cavity is provided within the support plate, near its center. This invention, through the arrangement of the piston and support plate, can uniformly disperse additives into the concrete, thereby reducing the mixing time and improving the uniformity of the mixture. The aforementioned patent specification mentions "a mixing device for processing high-strength crack-resistant concrete, comprising a mixing tank and a support plate disposed directly above it.

The second mixing blade, which is fixed outside the first mixing blade by a hinge, rotates with the first mixing blade to achieve secondary mixing of the high-strength crack-resistant concrete, thereby improving the mixing effect of the device. When needed, the unlocking screw located inside the hinge can be rotated to push the locking block to slide, thereby unlocking the splicing block and disassembling the second mixing blade to improve the practicality of the second mixing blade. 2. In this utility model, the conveying blades fixed to the outside of the mixing shaft improve the axial movement capability of the material through the thread design of the conveying blades themselves, thereby further enhancing the uniformity of mixing.

[0019] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0020] Example 1: A mixing device for processing high-strength crack-resistant concrete, referring to... Figures 1 to 4The system includes a mixing tank 1, which is the core component of the entire device. It is primarily used to contain and mix concrete materials. A reduction gear 2 is fixedly connected to the top of the mixing tank 1. The reduction gear 2 is crucial for ensuring the stable rotation of the mixing tank 1. Its main function is to gradually reduce the speed of the drive motor 31 through the internal rotation system of the reduction gear housing 21, ensuring that the mixing tank 1 mixes at a suitable speed and avoiding the impact of excessively fast or slow speeds on the mixing effect. A feed inlet 12 is fixedly connected to the top of the mixing tank 1, and a feed funnel 13 is fixedly connected to the top of the feed inlet 12. A discharge outlet 11 is fixedly connected to the bottom of the mixing tank 1, through which the material is discharged after thorough mixing. A stirring mechanism 4 is rotatably connected inside the mixing tank 1. Specifically, firstly, the material enters the inlet 12 through the feed funnel 13 and then into the mixing tank 1. Inside the mixing tank 1, the stirring mechanism 4 starts rotating to uniformly mix the material. Simultaneously, the deceleration mechanism 2 controls the rotation speed of the mixing tank 1 to ensure the stability and efficiency of the mixing process. After thorough mixing, the mixture is discharged through the outlet 11, completing the concrete processing. The entire process achieves uniform mixing and smooth discharge of materials, ensuring the quality of high-strength, crack-resistant concrete.

[0021] The stirring mechanism 4 includes a stirring shaft 41, which is the core component. The rotation of the stirring shaft 41 drives the rotation of the fixed ring 42 and the mounting block 44, thereby causing the first stirring blade 43 to perform preliminary stirring of the material. The stirring shaft 41 is externally rotatably connected to the inside of the mixing tank 1. Multiple fixed rings 42 are fixedly connected to the outside of the stirring shaft 41. Multiple mounting blocks 44 are fixedly connected to the outside of the fixed rings 42. The first stirring blade 43 is fixedly connected inside the mounting block 44. The secondary stirring assembly 5 is fixedly connected to the outside of the first stirring blade 43. The secondary stirring assembly 5 further enhances the stirring effect, ensures more uniform mixing of the material, and avoids uneven material mixing. Specifically, firstly, the stirring shaft 41 rotates inside the mixing tank 1, driving multiple fixed rings 42 to rotate. The fixed rings 42 are connected to multiple mounting blocks 44, and a first stirring blade 43 is fixed inside each mounting block 44. As the stirring shaft 41 rotates, the first stirring blade 43 begins to stir the materials. The secondary stirring assembly 5 further accelerates the stirring process, making the materials more uniform through secondary stirring. Throughout the process, the materials are continuously propelled to flow and mix within the mixing tank 1, ensuring the uniformity and consistency of the concrete.

[0022] The secondary stirring assembly 5 includes a hinge 51, which is fixedly connected to the outside of the first stirring blade 43. A locking shaft 52 is rotatably connected inside the hinge 51. A rotating block 53 is rotatably connected to the outside of the locking shaft 52. A second stirring blade 54 is fixedly connected inside the rotating block 53. A locking block 56 is slidably connected inside the splicing block 55. The outside of the locking block 56 is slidably connected to the inside of the first stirring blade 43. A return spring 57 is fixedly connected to the left side of the locking block 56. The other end of the return spring 57 is fixedly connected to the inside of the first stirring blade 43. An unlocking screw 58 is rotatably connected inside the hinge 51. The bottom of the unlocking screw 58 adopts a semi-circular shaft design. The left side of the unlocking screw 58 contacts the right side of the return spring 57. Specifically, firstly, hinge 51 is fixedly connected to the outside of the first stirring blade 43, and locking shaft 52 rotates via hinge 51. Rotating block 53 rotates via locking shaft 52, connecting the second stirring blade 54 to rotating block 53. When stirring is required, splicing block 55 slides onto locking block 56, allowing locking block 56 to slide freely inside the first stirring blade 43. During stirring, return spring 57 provides stable elastic force, restoring locking block 56 to its initial position. By rotating unlocking screw 58, the lock is released, allowing rotating block 53 and the second stirring blade 54 to rotate freely, thus enabling secondary stirring. After operation, unlocking screw 58 ensures smooth rotation through its semi-circular shaft design, and through the action of return spring 57, the entire assembly automatically returns to its initial position, ensuring the stability of the assembly and ease of operation.

[0023] The mixing tank 1 is externally fixedly connected to a support shaft 8, and the bottom of the support shaft 8 is fixedly connected to multiple support columns 9. The support columns 9 provide the necessary support force for the equipment to ensure that the equipment does not tilt or vibrate during the mixing process, and to avoid affecting the mixing effect due to equipment instability. The support columns 9 are externally fixedly connected to a bottom pad 10, the bottom of the bottom pad 10 is in contact with the top of the ground, and a connecting block is provided between two support columns 9. The connecting block of the support columns 9 further enhances the stability of the structure, so that the entire device remains balanced during operation. Specifically, the material enters the mixing tank 1 through the feed hopper 13, and the stirring shaft 41 drives the first stirring blade 43 to begin stirring the material. Simultaneously, the secondary stirring assembly 5 further enhances the stirring effect by rotating the second stirring blade 54. The mixing tank 1 is securely mounted on the support columns 9 via the support shaft 8, with the bottom of the support columns 9 in contact with the ground to ensure stability throughout the mixing process. A connecting block fixes the two support columns 9, further enhancing the structural stability of the equipment and preventing vibration and tilt from affecting the stirring effect. After thorough mixing, the material is discharged through the discharge port 11, completing the concrete processing.

[0024] Reference Figure 1 , Figure 5 , Figure 6 The deceleration mechanism 2 includes a deceleration housing 21. The bottom of the deceleration housing 21 is fixedly connected to the top of the mixing tank 1. A power gear 25 is rotatably connected inside the deceleration housing 21. Multiple rotating shafts 24 are rotatably connected inside the deceleration housing 21. Transmission gears 22 are fixedly connected to the outside of the multiple rotating shafts 24. Multiple drive racks 23 are fixedly connected to the inner wall of the deceleration housing 21. The multiple transmission gears 22 and drive racks 23 are coupled to each other to ensure stable adjustment of the rotation speed. The outside of the transmission gears 22 and the adjacent side of the multiple drive racks 23 are coupled to each other. The outside of the rotating shafts 24 and the outside of the multiple transmission gears 22 are coupled to each other. A linkage block 26 is fixedly connected to the top of the multiple rotating shafts 24. A drive assembly 3 is fixedly connected inside the linkage block 26. The outside of the stirring shaft 41 is fixedly connected to the inside of the rotating shaft 24. Specifically, firstly, the material enters the mixing tank 1 through the feed funnel 13 and begins mixing. The reduction mechanism 2 is secured to the top of the mixing tank 1 via a reduction housing 21. The working gear 25 and multiple rotating shafts 24 within the reduction housing 21 work together to couple the transmission gear 22 and the drive rack 23, gradually reducing the rotational speed to ensure the mixing shaft 41 operates at a suitable speed. The linkage block 26 transmits power through the rotating shaft 24, enabling the drive assembly 3 to rotate the mixing shaft 41. The first mixing blade 43 and the secondary mixing assembly 5 further mix the materials during rotation. Finally, the thoroughly mixed concrete is discharged through the discharge port 11, completing the entire processing. The entire device stabilizes the mixing process through the reduction mechanism 2, improving the uniformity and quality of the concrete.

[0025] The interior of the deceleration housing 21 has a rotating groove. The external part of the linkage block 26 is rotatably connected to the interior of the rotating groove. The opposite sides of multiple drive racks 23 are fixedly connected to the inner wall of the rotating groove. The external parts of the rotating shaft 24 and the external parts of the transmission gear 22 are rotatably connected to the interior of the rotating groove. Specifically, the material first enters the mixing tank 1 through the feed funnel 13 and begins mixing. The reduction mechanism 2 is securely mounted on the top of the mixing tank 1 via a reduction housing 21. The linkage block 26 is externally rotatably connected to the rotating groove inside the reduction housing 21, ensuring smooth transmission. Multiple drive racks 23 are fixedly connected to the inner wall of the rotating groove on one side. Through cooperation with the rotating groove, the drive racks 23 achieve synchronous rotation with the rotating shaft 24 and the transmission gear 22. The rotating shaft 24 and the transmission gear 22 are interconnected, jointly transmitting power to drive the mixing shaft 41 to rotate. The first mixing blade 43 and the secondary mixing assembly 5 further mix the materials during rotation, ensuring effective mixing. After thorough mixing, the concrete is discharged through the discharge port 11, completing the entire mixing process. The reduction mechanism 2, through stable rotation control, ensures a smooth and uniform mixing process, improving the quality and uniformity of the concrete.

[0026] The drive assembly 3 includes a drive motor 31, which is connected to the reduction mechanism 2 via a linkage block 26, thereby transmitting power to the stirring shaft 41 through the reduction mechanism 2. The drive end of the drive motor 31 is rotatably connected to a reduction housing 21, the drive end of the drive motor 31 is fixedly connected to the linkage block 26, the drive motor 31 is fixedly connected to the outside of a motor mounting bracket, the top of the reduction housing 21 is fixedly connected to a motor support block 32, and the bottom of the motor mounting bracket is fixedly connected to the top of the motor support block 32. Specifically, the drive motor 31 first provides power to the entire device through its drive end. The drive end of the drive motor 31 is externally rotatably connected to the reduction housing 21, driving the rotating components inside to start working. The drive end of the drive motor 31 is also fixedly connected to the linkage block 26 to ensure that the power can be effectively transmitted to the downstream components. The motor support block 32 is firmly fixed to the top of the reduction housing 21, and the motor mounting bracket supports the drive motor 31 to ensure stable operation of the motor. Through the continuous operation of the drive motor 31, multiple gears and rotating shafts 24 inside the reduction housing 21 work together to ultimately drive the stirring shaft 41 to rotate. The first stirring blade 43 on the stirring shaft 41 begins to stir the materials, ensuring the uniformity and efficiency of the mixing process. After thorough mixing, the concrete or other materials are discharged through the discharge port 11, completing the entire mixing process.

[0027] The stirring shaft 41 is fixedly connected to the outside of the conveying blades 6. The threaded design inside the conveying blades 6 enables the material to be effectively conveyed to different areas of the mixing tank 1, thereby improving the mixing effect. The conveying blades 6 have threads inside. The bottom of the stirring shaft 41 is fixedly connected to the corner stirring block 7. The corner stirring block 7 at the bottom of the stirring shaft 41 performs more fine stirring on the material at the bottom of the mixing tank 1, ensuring that the material at the bottom is also fully mixed. The bottom of the corner stirring block 7 is in contact with the bottom of the inner wall of the mixing tank 1. The center of the corner stirring block 7 has a triangular through hole. The corner stirring block 7 is a triangular block. Specifically, the material enters the mixing tank 1 through the feed funnel 13, and the stirring shaft 41 begins to rotate. Conveying blades 6 are fixedly connected to the outside of the stirring shaft 41. The threaded design of the conveying blades 6 allows them to effectively push the material along a predetermined direction, while simultaneously increasing the mixing effect. An edge mixing block 7 is fixedly connected to the bottom of the stirring shaft 41. The bottom of the edge mixing block 7 contacts the bottom of the inner wall of the mixing tank 1, ensuring thorough mixing of the material within the mixing tank 1. The edge mixing block 7 is a triangular block with a triangular through-hole in its center, allowing the material to flow evenly during the mixing process. Through the synergistic action of the stirring shaft 41, the conveying blades 6, and the edge mixing block 7, the material is ensured to be fully mixed within the mixing tank 1. Finally, the concrete or other materials are discharged through the discharge port 11, completing the entire mixing process.

[0028] The implementation principle of this application embodiment is as follows: The high-strength, crack-resistant concrete to be mixed is guided into the feed inlet 12 through the feed funnel 13, and then into the mixing tank 1 through the feed inlet 12. Then, the drive motor 31 fixed on the top of the motor support block 32 is started, which drives the reduction mechanism 2 fixed on the drive end of the drive motor 31 to rotate. During this process, the drive motor 31 drives the linkage block 26 fixed on the drive end of the drive motor 31 to rotate. During the rotation of the linkage block 26, the linkage block 26 drives the multiple rotating shafts 24 rotatably connected inside the linkage block 26 to rotate. Because the multiple drive racks 23 fixed inside the reduction housing 21 are coupled with the transmission gears 22 fixed outside the rotating shafts 24, the drive racks 23 rotate as they follow the rotation of the rotating shafts 24, and finally drive the work gear 25 to rotate. During the rotation of the working gear 25, the stirring mechanism 4 fixed inside the working gear 25 is driven to rotate. The working gear 25 drives the stirring shaft 41 fixed inside the working gear 25 to rotate. The stirring shaft 41 drives the multiple fixed rings 42 fixedly connected to the outside of the stirring shaft 41 to rotate. Then, the first stirring blade 43 is driven to rotate through the mounting block 44. The first stirring blade 43 stirs the high-strength crack-resistant concrete. The secondary stirring component 5 fixed outside the first stirring blade 43 performs secondary stirring of the high-strength crack-resistant concrete. During the secondary mixing of high-strength crack-resistant concrete, the first mixing blade 43 rotates with the mixing shaft 41. With the help of the centrifugal force generated by the rotation of the first mixing blade 43, the second mixing blade 54 rotates around the locking shaft 52 with the help of the rotating block 53. During the rotation of the second mixing blade 54, the high-strength crack-resistant concrete is mixed again. When maintenance of the second mixing blade 54 is required, the unlocking screw 58 fixed inside the hinge 51 can be rotated. The unlocking screw 58 pushes the locking block 56 in contact with the unlocking screw 58 to slide. During the sliding process, the locking block 56 releases the restriction on the splicing block 55, allowing the splicing block 55 to be separated from the inside of the first mixing blade 43, thereby achieving maintenance of the second mixing blade 54. Afterwards, the return spring 57 pushes the locking block 56 to reset. The conveying blades 6, fixedly connected to the outside of the mixing shaft 41, rotate with the mixing shaft 41. The threaded grooves inside the conveying blades 6 enhance the axial movement of the material. Simultaneously, the corner mixing blocks 7, fixed to the bottom of the mixing shaft 41, mix the high-strength, crack-resistant concrete at the bottom of the mixing tank 1, thus preventing dead zones from affecting the final product during mixing. Finally, the mixed high-strength, crack-resistant concrete is discharged from the mixing tank 1 through the discharge outlet 11. The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
