The automatic undisturbed soil collecting device according to claim 1, wherein: One side of the first bottom plate and the second bottom plate is respectively connected with a first hinge and a second hinge, the first bottom plate is rotatably connected to the bottom of the shell through the first hinge, and the second bottom plate is rotatably connected to the bottom of the shell through the second hinge.

7. The automatic undisturbed soil collecting device according to claim 1, wherein: The shell is a rectangular body, and the top surface of the shell is fixedly connected with a handle.

8. The automatic undisturbed soil collecting device according to claim 1, wherein: The first hydraulic machine and the second hydraulic machine are both provided with a pressure relief valve.

9. A method of collecting using the automated undisturbed soil collection apparatus of any one of claims 4 to 5, characterized in that: The method comprises the following steps: Step one: first remove the cover plate, open the first bottom plate and the second bottom plate at the bottom of the shell, place the shell horizontally on the ground to be sampled, and fix the cutting ring and the cutting ring fixing device according to the actual demand; Step two: rotate the adjusting knob to make the first hydraulic machine extend and stably support on the ground, place a person or an object on the opened first bottom plate and second bottom plate, and use a certain gravity to fix the shell on the ground; Step three: turn on the battery switch through the control panel, start the second automatic rocker arm device, after the second automatic rocker arm device starts to run, the second electronic turntable starts to rotate, the third fixed button drives the second rotating rod to rotate up and down with the second rotating button as the center within the diameter range of the second electronic turntable, the second rotating rod drives the second rocker arm to move up and down through the fourth fixed button, and the second rocker arm drives the telescopic rod of the second hydraulic machine to elongate through the second folding rocker, so that the cutting ring enters the soil; Step four: after the cutting ring enters the soil, stop the second automatic rocker arm device through the control panel; Step five: remove the person or object on the first bottom plate and the second bottom plate. Step six, start the first automated rocker device through the operation panel, after the first automated rocker device starts to run, the first electronic turntable starts to rotate, the first fixed button drives the first rotating rod to rotate up and down within the diameter range of the first electronic turntable with the first rotating button as the center, the first rotating rod drives the first rocker to move up and down through the second fixed button, the first rocker drives the telescopic rod of the first hydraulic machine to elongate through the first folding rocker, so that other parts of the first hydraulic device rise, and the ring knife moves to the soil surface; Step seven, separate the ring knife from the ring knife fixing device, take out the ring knife and its soil sample and save them; Step eight, adjust the pressure relief valve of the first hydraulic machine and the second hydraulic machine, so that the first hydraulic device and the second hydraulic device return to the initial state; Step nine, close the cover plate, end the soil sample collection or reinstall the ring knife to continue sampling.
