[0002] A powder sampling device is a device used to obtain samples of powdered materials. It is usually composed of a sampler, a sampling tube and a control system. When in use, the sampler will send the sample collected from the material flow into the sampling tube, and then process and analyze the sample through the control system. The application range of the powder sampling device is extremely wide. For example, in the field of concrete production, the proportion of raw materials input during concrete configuration directly affects the density and firmness of the concrete. Therefore, a large number of small tests and multiple pilot tests are required during configuration in order to design a concrete mix ratio that meets the requirements. Multiple sampling from the powder tank is required for testing.

[0003] The traditional powder sampling devices on the existing market still have some defects when in use. For example, the samples in the powder need to be manually inserted into the collection box into the powder for sampling. The powder can easily cause damage to human hands, and powder in different positions cannot be sampled at the same time, which reduces work efficiency. For this reason, we propose a powder sampling device. Utility Model Content
