Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-2, a shallow soil sampling device for geological exploration comprises a sampling rotating rod 2 and a sampling tube 4, wherein an internal thread sleeve 3 is welded and fixed at the axis of the top end of the sampling tube 4, the sampling rotating rod 2 is installed in the internal thread sleeve 3 through threads, a conveying screw 5 is welded and fixed at the bottom end of the sampling rotating rod 2 and extends into the sampling tube 4, a soil sample collecting tank 6 is installed at the bottom of the sampling tube 4 through threads, and a rotary table 1 is installed at the top end of the sampling rotating rod 2.

The upper half part of the sampling rotating rod 2 is provided with a thread matched with the internal thread sleeve 3, and the sampling rotating rod 2 is further fixed with a limit nut 10.
