Transformer substation soil sampling tool and sampling method

The invention belongs to the technical field of soil sampling, and particularly relates to a transformer substation soil sampling tool and a sampling method. The transformer substation soil sampling tool comprises a support, a main shaft, a driving mechanism, a rotating shaft, a supporting plate, a rotating mechanism, a drilling barrel, a transverse cutter and an adjusting mechanism. The main shaft and the support are in sliding connection. The driving mechanism is connected with the main shaft. The rotating shaft and the main shaft are in rotating connection. The supporting plate is slidablyconnected with the support and rotatably connected with the rotating shaft. The rotating mechanism is arranged on the supporting plate and connected with the rotating shaft. A first end of the drilling barrel is connected with the rotating shaft, and a second end is provided with a longitudinal cutter. And the transverse cutter is arc-shaped, is rotationally connected with the drilling barrel andis used for cutting soil i
