Description

Technical Field

[0001] This utility model specifically relates to a self-cleaning concrete mixing device for road and bridge construction, belonging to the field of road and bridge construction. Background Technology

[0002] In bridge and road construction, concrete mixing plants are indispensable key equipment, and their performance and maintenance directly affect the quality of concrete and construction efficiency. However, in actual use, the cleaning of mixing plants has gradually become a prominent issue, becoming a significant factor affecting construction quality and cost.

[0003] After a concrete mixing operation, a large amount of concrete often remains on the inner walls of the mixing tank and the splash guard. Once dried and hardened, this residual concrete adheres firmly to the inner walls of the mixing unit, making it difficult to clean thoroughly. On one hand, this leads to material waste, as the residual concrete cannot be reused, increasing construction costs. On the other hand, the residual concrete alters the internal space of the mixing unit and the effective working area of ​​the mixing blades, affecting the quality of the concrete mixed in the next operation.

[0004] Currently, traditional cleaning methods mainly rely on manual labor, which is not only inefficient but also makes it difficult to guarantee the cleaning effect. Manual cleaning requires a lot of time and labor, and the cleaning personnel face high safety risks due to the confined space and harsh environment inside the mixing unit. In addition, manual cleaning often fails to completely remove concrete adhering to the inner walls of the mixing tank and splash guards, and residual concrete may detach and mix into the new concrete during the next mixing, affecting the quality stability of the concrete.

[0005] With the continuous advancement of construction technology, higher demands are being placed on the efficiency and quality of cleaning concrete mixing plants. Therefore, there is an urgent need for a technical solution that can effectively address the difficulties in cleaning mixing plants, thereby improving construction efficiency, reducing costs, and ensuring concrete quality and construction safety.
