This invention relates to the field of soil sampling device technology, and more particularly to a mountable UAV soil sampling device for land reclamation. The device comprises an upper shell, a lower shell, a drilling assembly, and an air pump assembly. The upper shell is fixedly mounted on the top of the lower shell via a mounting buckle, which is then bolted to both the upper and lower shells. A bracket is fixedly mounted on the bottom of the lower shell. This invention, by installing an outer cylinder outside the guide cylinder, creates a double-layered cylindrical guiding structure.
