The invention relates to a bark Chinese herbal medicine picking machine, which comprises a rotary clamping fixing frame, a rotary lifting mechanism and a regeneration protection mechanism. When the machine is used, the clamping fixing frame is clamped to a tree trunk, a connecting belt is retracted into a groove in the upper end of the clamping fixing frame, and the position of a nut is adjusted to enable a cutting blade to reach a proper position. A motor drives a rotating mechanism to clamp the tree trunk, a gear J drives the cutting blade to advance to a certain position and incline by a certain angle, and the motor drives the whole machine to rotate to strip the tree bark. After stripping is completed, the trunk is loosened, a lifting mechanism clamps the trunk, the machine is lifted to a certain position, the trunk is loosened, the trunk rotates a rotatable connecting plate to a certain position, a film pressing plate presses a film on the trunk, pesticide is evenly sprayed to the trunk, and the trunk is wrapped by the film for protection. In this way, the steps of stripping, pesticide spraying, film wrapping and the like are completed at a time, the picking time is saved, manpower is saved, the stripping thickness is controllable, and tree death caused by damage to phloem can be prevented.
