[0002] Chemical raw materials can generally be divided into two categories: organic chemical raw materials and inorganic chemical raw materials. In the raw material processing process of chemical experiments, a variety of raw materials need to be combined. The premise is to fully mix the reacting substances, and the natural mixing of liquids is slow and inefficient. , and the mixing is not sufficient. Using a stirring device to mix chemical raw materials can improve the mixing efficiency and make the chemical raw materials fully mixed. Corrosive chemical raw materials use sampling devices to extract chemical raw material samples, so that they can be extracted through analysis and detection. samples to judge the quality of the overall chemical raw materials

[0003] The current chemical raw material sampling device adopts a single sampling method, which cannot perform multi-layer sampling and cannot adapt to various sampling environments. Moreover, the sampling device has a complex structure, inconvenient disassembly and assembly, high manufacturing costs, low work efficiency, and cannot achieve sufficient mixing of raw materials. During the stirring process, the stirring device cannot perform layered sampling of the stirred chemical raw materials, and cannot judge whether the degree of mixing of raw materials meets the requirements. Therefore, the sampling function is single, resulting in inaccurate sampling and detection results, and the sampling device cannot conveniently take out samples. Personnel need to extract manually, which consumes a lot of manpower, and it is impossible to adjust the dose of the sample. There is a certain error in sampling, which makes the sampling test data inaccurate
