Description

Technical Field

[0001] This utility model relates to the field of concrete mixing technology, and in particular to a concrete mixing device for building construction. Background Technology

[0002] In the construction industry, concrete is an extremely important building material, and its quality directly affects the overall quality and safety of the construction project. As the core equipment for concrete preparation, the concrete mixing plant undertakes the crucial task of uniformly mixing raw materials such as cement, aggregates, and water in the correct proportions. With the rapid development of the construction industry, higher demands are placed on the performance of concrete mixing plants. Not only is it necessary to ensure the uniformity of mixing to guarantee concrete quality, but it is also desirable for the plant to have convenient disassembly and maintenance capabilities, facilitating the cleaning or replacement of key internal components such as the auger blades. This improves the equipment's efficiency and service life, adapting to the diverse concrete needs of different construction scenarios.

[0003] Traditional concrete mixing plants for construction often feature a single integrated mixing drum and internal components such as the auger blades, or a complex, fixed connection. Over long-term use, concrete materials tend to accumulate and clump on the inner wall of the mixing drum and the auger blades. If not cleaned promptly, this can affect the mixing quality of subsequent concrete and reduce its uniformity. Furthermore, when the auger blades wear down and need replacement, the disassembly process is extremely cumbersome due to the limitations of the connection structure, often requiring significant time and manpower, severely impacting construction progress. In addition, traditional devices have shortcomings in sealing performance, potentially leading to material leakage during mixing, resulting in material waste and environmental pollution.

The spiral blades 11 are in contact with the inner walls of the cylinder 1 and the conical sleeve 4, which allows the spiral blades 11 to stir the materials inside the cylinder 1 and the conical sleeve 4.

[0026] Working principle: When the drive motor 23 starts, its output end drives the drive gear 24 to rotate. The drive gear 24 meshes with the driven gear ring 26, thereby driving one of the conical sleeves 4 to rotate. Since the cylinder 1 and the conical sleeve 4 are connected by the insert rod 6, the rotating part 9, etc., the cylinder 1 and the internal spiral blades 11 rotate together. The concrete raw material entering from the inlet / outlet cylinder 27 is fully contacted and mixed with the inner wall of the cylinder 1 and the conical sleeve 4 under the stirring action of the rotating spiral blades 11. The connecting rod 12 on the surface of the spiral blades 11 further assists in stirring. Stirring enhances the mixing effect. When it is necessary to clean or replace the spiral blade 11, use a tool to rotate the rotating part 9. The rotating part 9 moves on the fixed block 5 and drives the insert rod 6 to move, pulling the insert block 8 out of the insert groove 7. This disconnects the conical sleeve 4 from the cylinder 1 and other components, allowing the spiral blade 11 to be operated accordingly. At the same time, the sealing ring gasket 3 ensures the sealing performance of the device during the stirring process, preventing raw material leakage. The support leg 17 is trapezoidal to ensure the stability of the device. The support turntable 20 and the rotating sleeve 25 cooperate to make the cylinder 1 and other components rotate and stir more smoothly.

[0027] The wiring diagram of the drive motor 23 in this utility model is common knowledge in the field. Its working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the drive motor 23 will not be explained in detail.
