[0002] Mining generally includes exploration, development, mining, processing and other stages. Sampling work is carried out in these different stages, and the purpose of each stage may be different. For example, in the mining process, sampling is to identify the grade of ore, guide sorting (such as distinguishing high and low grade ore), and avoid invalid processing in the subsequent process. After the mining is completed, the ore is generally transmitted to the ground in stages by the transmission belt for subsequent processing. At present, the sampling work in the ore transmission process is generally realized by industrial robots (mechanical hands) clamping "sampling spoons" to regularly dig quantitative ore on the transmission belt. However, the price of industrial robots is generally expensive, which on the one hand increases the sampling work cost, and on the other hand industrial robots need to be programmed to realize sampling work. If the industrial robot changes the sampling station, the original program will not support the sampling work, and professional technicians need to reprogram to realize the sampling work, which brings certain trouble to the sampling work.
