Drug sampling mechanism capable of preventing pollution

The utility model provides a medicine sampling mechanism capable of preventing pollution. The medicine sampling mechanism comprises a medicine tank, a sampling tank and an excess material recycling tank arranged below the sampling tank, according to the device, the independent sampling tank is arranged, and the sampling box of which the height and the direction can be adjusted through the adjusting assembly is arranged in the sampling tank, so that powdery medicines in the sampling tank can be directly taken into the sampling box, and the open end of the sampling box can face the material taking through groove after being lifted and rotated; then the sample in the sampling box is taken out under the driving of the material pushing assembly, and before the sampling box is completely aligned with the material taking through groove, the material receiving plate always covers and shields the material taking through groove, so that external air is prevented from entering the sampling tank, and during sample taking
