In actual use, the three-axis stabilization system comprises an X-axis self-stabilization system, a Y-axis self-stabilization system and a Z-axis self-stabilization system, wherein the X-axis self-stabilization system comprises an X-axis axial direction self-stabilization system and a self-stabilization system rotating around the X axis, the Y-axis self-stabilization system comprises a Y-axis axial direction self-stabilization system and a self-stabilization system rotating around the Y axis, and the Z-axis self-stabilization system comprises a Z-axis axial direction self-stabilization system and a self-stabilization system rotating around the Z axis, so that 6 self-freedom degree constraints are realized. Generally, the X-axis axial direction self-stabilization system is a horizontal first limiting spring 10, the X-axis rotation direction self-stabilization system is a horizontal first bidirectional rolling bearing 9, the Y-axis axial direction self-stabilization system is a horizontal second limiting spring 13, the Y-axis rotation direction self-stabilization system is a horizontal second bidirectional rolling bearing 12, the Z-axis axial direction self-stabilization system is a vertical limiting spring 14, and the Z-axis rotation direction self-stabilization system is a top bidirectional rolling bearing 6. When in actual use, the stable system of the undisturbed soil sample transportation device has the following specific working states: firstly, translating along an X-axis, when a transport carrier accelerates or decelerates along the advancing direction, due to the inertia effect, a soil sample barrel 3 can translate backwards or forwards relative to a box body 1, one side of a spring is retracted and pulled and one side of the spring is pressed under the action of a horizontal first limiting spring 10, and the X-direction translation of the soil sample barrel is limited, so that automatic leveling and stabilization are realized; rotating around an X axis, when one side of the transport carrier is raised to a road condition or heels through a hollow, the box body 1 can rotate around the X axis, and under the self weight of the horizontal second bidirectional rolling bearing 12 and the soil sample, the rotation of the box body 1 cannot influence the soil sample cylinder 3, namely the soil sample cylinder 3 reversely rotates relative to the box body, so that automatic leveling and stabilization are realized; thirdly, translating along the Y axis, when the transport carrier is bent excessively, the soil sample cylinder 3 translates along the Y axis relative to the box body 1 under the action of centrifugal force and inertia, one side of the spring is retracted and pulled and one side of the spring is pressed under the action of a horizontal second limiting spring 13, and the Y-direction translation of the soil sample cylinder 3 is limited, so that automatic leveling and stabilization are realized; and fourthly, the box body 1 rotates around the Y axis when the transport carrier climbs a slope, goes downhill or passes through a rough road.
