The invention relates to a planet truck testing soil tank with pitching rotation and side-tipping rotation functions, and aims to solve the problem that a soil tank for testing the climbing ability, the lateral slope climbing slip property, the side slip limit and the combined slope moving property of a planet truck is absent at present. The soil tank comprises a testing soil tank unit, a pitching movement mechanism, a bottom supporting mechanism, a side-tipping movement mechanism and a foundation part, the pitching movement mechanism is fixedly arranged at the bottom end of the testing soil tank unit and is close to the left side of the testing soil tank unit, the bottom supporting mechanism is fixedly arranged at the bottom of the testing soil tank unit and is close to the right side of the testing soil tank unit, the side-tipping movement mechanism is arranged at the bottom end of the testing soil tank unit and is aligned to the bottom supporting mechanism in the width direction of the testing soil tank unit, the lower end of the pitching movement mechanism, the lower end of the bottom supporting mechanism and the lower end of the side-tipping movement mechanism are fixed onto the foundation part, and the planet truck testing soil tank is used for testing the performance of the planet truck.
