Problems solved by technology

[0003] In the existing mixing and preparation process of cemented sand and gravel materials and concrete materials, the material weighing system usually adopts static weighing or dynamic weighing technology, and the materials are batched according to a certain ratio through the batching equipment. Material preparation requirements, but there are also some problems

For example, the static material weighing system of the mixing station is to weigh each material required for each mixing production according to the mixing ratio requirements, through the weighing sensor arranged on the batching equipment. Mixing is carried out after mixing tanks. Although this batching system can ensure accurate weighing of each material, it cannot be continuously batched due to the limitation of batching equipment and batching methods, and the amount of mixture prepared each time is limited, and the batching efficiency is very low.

Later, with the great increase in the demand for the mixing output of cemented sand and gravel materials and concrete materials, the defects of the static weighing batching system became more and more obvious, and a batching equipment and batching method based on dynamic weighing technology was produced. , The dynamic material weighing system overcomes the discontinuous shortcomings of traditional static weighing, and greatly improves the mixing output and mixing efficiency. However, in the actual production process, when the fluidity of the material is not good, it will cause overshoot fluctuations, A series of adverse consequences such as out-of-tolerance batching, inaccurate buckle weighing, and prolonged batching time; at the same time, due to the long-term continuous operation of the equipment, the weighing sensor will also cause weighing deviations. Due to the difficulty of dynamic weighing and calibration, and weighing deviations are not easy It was found that, resulting in uneven mixing of the mixture, large dispersion of strength, and potential quality hazards
