The invention belongs to the technical field of agricultural machinery, and particularly relates to a radix ophiopogonis combined harvester. The radix ophiopogonis combined harvester comprises a machine frame (1), a crawler base plate (6), a transmission device (7), a harvesting device (8) and a collecting device. The harvester uses a line harvesting mode; the harvesting quality is ensured. Through a guide device (9), two lines of radix ophiopogonis are guided into a conveying clamp chain (21), so that the harvesting unpicking rate is reduced; the harvesting quality is improved. The harvesteruses a soil removing device (12) to remove soil attached onto tubers of radix ophiopogonis. Through the reciprocating movement and an extruding process of a soil removal plate (22), the soil is removed, so that the harvesting soil content is reduced. The harvester uses a circular disc cutter (15) cutting device, so that the tubers of the radix ophiopogonis in the harvesting process are separated from plants; the one-step harvesting of the radix ophiopogonis is realized; the labor cost is reduced.
