Powdery material sampling device

The utility model discloses a powdery material sampling device. The powdery material sampling device comprises a pneumatic conveying pipeline, an installation seat, a sampling machine body and a sample discharge tube, wherein a first through hole is formed in the sidewall of the pneumatic conveying pipeline; a second through hole is formed in the installation seat; a third through hole is formed in the sidewall of the sampling machine body; the first through hole, the second through hole and the third through hole are sequentially aligned and communicated to form a sample feeding channel; the sampling machine body is provided with a first accommodating space; the first tail end of the sampling machine body is communicated with the sample discharge tube to form a sample discharge channel. The powdery material sampling device is capable of greatly reducing the workload of operating personnel and capable of avoiding injuries caused on the bodies of the operating personnel; a sampling process is integral sampling and therefore meets the requirements specified by the 'General Rules for Sampling Solid Chemical Products' GB/T6679-2003 standards, and the sampling representativeness is high; in addition, because during a sampling process, sample feeding is carried out by the pneumatic conveying pipeline and the sample feeding channel, and sample discharge is carried out by the sample discharge channel, the possibility of manual operations is reduced, therefore, the probability of adulteration can be reduced.
