The controller controls the second power device 104 to rotate forwards, the second power device 104 drives the sampling tube 108 to slide downwards along the first sliding hole, the piston column 101 of the piston is fixedly connected with the mounting box 107 through the fixture block 102, so that when the sampling tube 108 moves downwards, the piston and the sampling tube 108 slide forwards and relatively, the volume of the cavity at the lower end of the sampling tube 108 is increased, when the tube opening at the lower end of the sampling tube 108 is in contact with the ground, the second power device 104 continues to rotate forwards to drive the sampling tube 108 to move downwards, the sampling tube 108 is embedded into the ground, and the cavity at the lower end of the sampling tube 108 is filled with a soil sample. The controller controls the first power device 106 to be started, the output shaft of the first power device 106 drives the mounting box 107 to rotate, and the rotating mounting box 107 drives the sampling pipe 108 to rotate. When the cavity at one end of the sampling tube 108 filled with the soil sample rotates to the collecting device, the controller controls the second power device 104 to rotate reversely, similarly, the piston and the sampling tube 108 slide reversely and relatively, the volume of the cavity filled with the soil sample in the sampling tube 108 is reduced, the soil sample is extruded out of the sampling tube 108, and then the soil sample is collected by the collecting device, and the soil sample collection at the point is completed.
