[0002] A powder sampler, also known as a powder sampling rod, a full-layer sampler, a powder sampling stick, or a trough sampler, etc., is a device used to collect samples of powdery materials. Powder samplers have been widely used in multiple industries, including but not limited to the pharmaceutical industry (such as the powder of active pharmaceutical ingredients), the food industry (such as the collection of corn, soybeans, rice, seeds, peanuts, wheat, grains), and the chemical industry (such as the sampling of sterile preparations, dairy products, cosmetics, as well as lithium batteries, catalysts, silicon powder, coal powder, ore powder, metal powder, etc.).

[0003] The principle of the powder sampler in the prior art is to add a screw rod inside the sampling sleeve, connect a small motor on the outside, insert the sleeve into the material, and drive the screw rod to rotate through the motor inside, bringing the material from the bottom to the discharge port to achieve the sampling process.

[0004] However, the existing screw-type samplers have the following disadvantages: a power source needs to be carried on-site and it is not convenient for personal carrying; if there are impurities with higher hardness in the material, jamming may occur. Summary of the Utility Model

[0005] In view of the above technical problems in the related art, the present utility model proposes a portable powder sampler, which can overcome the above-mentioned deficiencies of the prior art.

[0006] To achieve the above technical objectives, the technical solution of the present utility model is realized as follows:

[0007] A portable powder sampler;

[0008] The portable powder sampler includes a sampling sleeve. A plurality of layers of sleeve feed holes are provided on the side wall of the sampling sleeve. Below the inner cavity of the sampling sleeve, there is a sampling chamber. On the top wall of the sampling chamber, there are a fixed rod and a sampling port rotating rod, and the sampling port rotating rod is used to open and close the sampling chamber feed port on the sampling chamber.

[0014] Furthermore, a rotating handle is provided at the top of the sampling port rotating rod.

[0015] Furthermore, the perforation rate of the sleeve feed hole on the sampling sleeve is greater than 5% and less than 10%.

[0016] Furthermore, when the sampling port rotating rod rotates forward, it drives the sampling chamber feed cover on the sampling chamber to open the sampling chamber feed port. When the sampling port rotating rod rotates backward, it drives the sampling chamber feed cover on the sampling chamber to close the sampling chamber feed port.

[0017] Furthermore, an inner layer for adjusting the feed hole diameter is arranged inside the cylindrical part of the sampling sleeve. The inner layer feed holes on the inner layer for adjusting the feed hole diameter are adapted to the distribution positions of the sleeve feed holes, and the sizes of the inner layer feed holes on the inner layer for adjusting the feed hole diameter are set according to the specifications of the powder material to be processed.
