[0002] The grain sampler is a tool for extracting representative samples from a large amount of grain, widely used in agriculture, food processing, quality detection and other fields. Its main function is to ensure that samples are randomly and uniformly collected from the entire grain pile or batch, so as to accurately evaluate the quality of the grain. The grain sampler is usually composed of a long tube, a layering device, a sampling head and other parts, which can collect samples of different levels and positions according to the preset method, avoiding deviation. Through scientific sampling, the moisture, impurities and mold of the grain can be effectively detected, ensuring food safety and quality control.
[0003] At present, grain sampling mainly relies on simple sampling devices, which usually use tubular structures for sampling. However, the tubular sampler has obvious shortcomings, as its sampling method cannot represent the quality characteristics of the entire grain pile. Such equipment can only extract samples from the process of grain entering and exiting, usually limited to a certain level of grain, and cannot achieve layered sampling of different levels of grain. At the same time, the extracted samples will lose the characteristics of clear layers due to mixing and pouring, resulting in the inability to detect each level of grain individually and specifically.
[0004] Based on this, we propose a grain sampler to solve the above-mentioned problems. SUMMARY
