Abstract
Description
Technical Field
[0001] This utility model relates to the field of metering and regulating hopper technology, and in particular to a precise metering and regulating hopper for concrete raw materials. Background Technology
[0002] Concrete, as the most widely used building material in modern construction engineering, directly affects the safety and durability of building structures. Concrete is made by mixing cement, aggregates, water, and admixtures in specific proportions. The accuracy of the proportions of each raw material plays a crucial role in the strength, workability, and durability of concrete. Excessive cement content may lead to concrete cracking, while insufficient content will reduce strength. An unreasonable aggregate gradation will affect workability, thereby impacting construction techniques and quality. Therefore, accurate metering of raw materials is a core element in ensuring stable concrete quality during the concrete production process. Furthermore, under the current increasingly stringent environmental policies, concrete production enterprises face pressure to conserve energy, reduce emissions, and lower costs. Accurate metering can effectively reduce raw material waste, lower production costs, and reduce environmental pollution caused by raw material waste. Therefore, developing a high-precision, intelligent, and flexibly adjustable concrete raw material metering and regulating hopper has become an urgent need for the concrete production industry to improve product quality, increase production efficiency, and achieve sustainable development.
[0003] Currently, metering hoppers on the market mainly consist of hopper body structural components and feeding adjustment components. Traditional concrete raw material metering often uses simple mechanical metering methods operated manually. Manual metering is greatly affected by human factors, as different operators have different experience and operating habits, making it difficult to guarantee the accuracy and consistency of each measurement. In actual production at mixing plants, this can also lead to potential engineering quality problems. Simple mechanical metering equipment, such as early lever scales and hopper metering devices, has limited metering accuracy and is easily affected by equipment wear and material adhesion factors during long-term use, leading to a gradual increase in metering errors. In addition, the diversification and complexity of construction projects have placed higher demands on concrete performance. For example, the production of high-strength concrete, self-compacting concrete, high-performance concrete, and special concrete relies more on accurate raw material metering. Traditional metering methods and equipment can no longer meet these new demands, seriously restricting the development of concrete production enterprises and the improvement of construction project quality.
