Further, the drill bit is in threaded connection with the sampling tube.

Furthermore, the sampling ports are arranged in two numbers and are symmetrically distributed.

Furthermore, the opening is provided with two, is the symmetric distribution.

Further, a drill rod handle is arranged at the upper end of the drill rod.

Further, an inner rod handle is arranged at the upper end of the inner rod.

Further, when the inner rod handle is perpendicular to the drill rod handle, the opening is aligned with the sampling port.

The utility model discloses following beneficial effect has:

the utility model discloses a selenium-enriched soil sampling device in nonirrigated farmland, under the exogenic action, go deep into soil depths with drill bit and sampler barrel, then the interior pole of rotation makes the opening of inner tube and the sample connection of sampler barrel align, and like this sub-soil will be in proper order through sample connection and opening drop the sampler barrel in, then will take a sample the sample on the ground can be accomplished to the sampler barrel pull out. The sampling device has the advantages of simple structure, understandable principle, simplicity and convenience in operation, small environmental damage in the sampling process and suitability for sampling sandy soil.
