[0022] Further, the sampling barrel 2 is movably connected to the inside of the vehicle body 1, the motor 3 is located at the top of the sampling barrel 2, one end of the fixed block 10 is fixedly connected to one side of the sampling barrel 2, the rotating shaft 4 is rotatably connected to the inside of the sampling barrel 2, the spiral blade 5 is movably connected to the inside of the sampling barrel 2, the top of the sampling barrel 2 is fixedly connected to the guide plate 8, and a collection box 12 is provided at the bottom of one end of the guide plate 8;

[0023] When the bottom of the soil-breaking cone 6 enters the soil, the motor 3 is started, the motor 3 will drive the rotating shaft 4 to rotate, the rotating shaft 4 will drive the spiral blade 5 and the soil-breaking cone 6 to rotate, so that the soil enters the bottom of the spiral blade 5, and as the spiral blade 5 rotates inside the sampling tube 2, the spiral blade 5 drives the soil to move upward on its surface. When the soil reaches the top of the sampling tube 2, it will enter the inside of the guide plate 8 as the spiral blade 5 rotates, and then enter the inside of the collection box 12 through the guide plate 8 for collection;
