Description

Technical Field

[0001] The invention relates to the technical field of concrete processing, in particular to an automatic concrete mixing device. Background Art

[0002] Concrete, abbreviated as "tóng", refers to an artificial stone made of cementitious materials, aggregates (including coarse aggregates and fine aggregates), water and possible admixtures, additives and other materials in appropriate proportions, which are mixed, molded, cured and hardened. Ordinary concrete uses cement as the main cementitious material, which is mixed with water, sand, gravel and other materials in proportion. Chemical admixtures and mineral admixtures can be added when necessary. It is formed after uniform mixing, dense molding, curing and hardening. Concrete is widely used in civil engineering and is one of the most important civil engineering materials in contemporary times. The quality of concrete is directly related to the safety, durability and functionality of buildings. Once there is a problem with the quality of concrete, a series of serious consequences may occur, as follows: Insufficient strength of concrete may result in insufficient bearing capacity of the building or structure, unable to withstand the design load, resulting in deformation or even collapse of the structure. In extreme cases, this hazard may pose a threat to personnel safety. Poor durability of concrete may lead to early cracking, spalling or corrosion, especially in harsh environments such as salt water erosion, acid rain, etc. These damages will shorten the service life of the building and may require more frequent repairs and replacements. If the porosity of concrete is high, it may lead to poor waterproofing, and moisture and harmful substances can easily penetrate into it, accelerating the corrosion of steel bars and the damage of concrete. This will not only affect the normal use of the building, but may also cause mildew and other health problems inside the structure. In cold areas, poor quality concrete may not be able to resist the damage of freeze-thaw cycles, resulting in surface spalling and structural damage. This will further reduce the durability of the concrete and the overall stability of the structure. Due to the above problems, concrete structures may require frequent repairs and replacements, greatly increasing the long-term maintenance costs. This not only increases the economic burden, but may also lead to the delay or cancellation of other planned projects. Damage such as cracks and spalling not only affects the structural safety, but may also damage the appearance and reduce the aesthetic value of the building. For some buildings with high requirements on appearance, such as commercial buildings and art galleries, poor quality concrete may seriously affect their image and value.

[0003] Therefore, in order to ensure that the concrete can reach the optimal state required for construction when mixed, a concrete mixing equipment that can accurately control the proportion of concrete materials is needed to solve the above problems. Summary of the invention
