[0002] In industrial production processes, especially when it comes to the processing of bulk materials such as coal, ore, and chemical raw materials, accurate material composition analysis is of vital importance for production quality control, process optimization, and trade settlement. Traditional material sampling methods often rely on manual operations, which is not only inefficient but also difficult to ensure the representativeness and uniformity of the collected samples. Due to the high randomness of manual sampling, the collected samples may not truly reflect the characteristics of the entire batch of materials, thereby affecting the accuracy of subsequent analysis results.

As a common equipment for continuous transportation of bulk materials, belt conveyors have to realize automated, efficient and accurate sampling operations during their operation, which has become an inevitable trend in the development of the industry. Although some existing sampling equipment has achieved automation to a certain extent, there are still many shortcomings. For example, some equipment has a complex structure and high maintenance costs, or it is easy to cause sample waste and contamination during the sampling process, affecting the sample quality, and thus cannot meet the needs of large-scale, high-precision industrial production.
