The invention relates to a vibration direct-pushing sampling drilling tool and a sampling method thereof. The vibration direct-pushing sampling drilling tool comprises an outer drilling pipe and further comprises an inner drilling rod and a sampling pipe which are selectively arranged in the outer drilling pipe; when the inner drill rod is arranged in the outer drill pipe, the inner drill rod can seal the lower opening of the outer drill pipe; when the sampling pipe is arranged in the outer drill pipe, the sampling pipe can be communicated with the lower opening of the outer drill pipe to form a soil inlet channel; the salvage lifting mechanism can be arranged in the outer drill pipe and is detachably connected with the inner drill pipe or the sampling pipe arranged in the outer drill pipe, and the salvage lifting mechanism is used for lifting the inner drill pipe or the sampling pipe to be separated from the outer drill pipe. The sampling device has the beneficial effect that multiple sampling modes can be r
