Description

Technical Field

[0001] The utility model relates to a powder sampler. Background Art

[0002] Powder samplers are mainly used for detecting and sampling during the production process or discharging of powdery or granular materials. At present, most powder samplers on the market are manual, such as those with spoon-shaped sampling heads, or there are also some electric handheld samplers, which receive samples manually. However, the production and discharging time of many powder materials is continuous for a long time. If sampling is required at certain intervals, personnel need to be arranged to be on duty, resulting in high labor costs, and problems such as unstable sampling time intervals, unstable sampling amounts, and even forgetting to sample are likely to occur. In addition, the powder sampling environment often has high noise and dust, which poses certain occupational hazards to operators. It can be seen that the existing powder samplers need to be improved to better conform to the current automated production mode. Content of the Utility Model
