The invention relates to a long-rhizome Chinese medicinal herb harvester, which consists of a seedling separating device, a colter, a front support, a bolt, a vibrating digger shovel, a gripper wheel, a vibrating rod, a hydraulic motor, a driving wheel, a ripping belt, a tension pulley, a stander, a vibrating seat, a rear eccentric shaft, a rear eccentric receiving pan, a front eccentric receiving pan, a front eccentric shaft, a shaft bracket, a small chain wheel, a universal coupling, a hanging rack, an input shaft, a large chain wheel and a supporting frame. The seedling separating device, the colter and the hanging rack are arranged on the stander respectively; one end of the vibrating digger shovel is arranged on the front support, and the other end of the vibrating digger shovel is arranged on the vibrating rod; the vibrating rod is connected with the vibrating seat; and the driving wheel, the tension pulley and the gripper wheel are wound on the gripping belt respectively. The product can reduce the labor intensity of operators and improve the harvesting efficiency; the depth of operation and the amplitude of the harvester can be adjusted according to different varieties of the Chinese medicinal herbs, the growth depth of the rhizomes and the different characteristics of the plants; and the harvested medicinal materials are not broken and cannot crack; therefore, the grade and the quality of the herbs are improved.
