[0002] At present, for the harvest of many kinds of rhizome medicinal materials such as astragalus, baical skullcap, siler, adiantum capillus-veneris and platycodon, still rely on manual digging or simple instrument digging, the labor intensity is big, and the working efficiency is low, and the rhizome of medicinal material is very easy to damage, and the quality of medicinal material is affected.

[0003] Chain type dig medicine machine is mainly used for the collection of medicinal materials, which can efficiently and accurately dig medicinal materials, reduce the labor intensity and time cost of manual collection. The chain type dig medicine machine pulled by the tractor mainly consists of a reduction system, a chain transmission mechanism and a soil conveying belt frame. These systems and mechanisms work together to realize the digging, conveying and collecting of medicinal materials. The reduction system usually adopts a gearbox: the power transmitted by the transmission shaft of the tractor is decelerated to adapt to the working requirements of the dig medicine machine. The chain transmission mechanism: through the chain sprocket transmission, the power is transmitted to the soil conveying belt frame to realize the separation of soil and medicinal materials during conveying. However, the existing dig medicine machines often use fixed spades at the front end of the frame to dig soil, for example, the utility model patents with announcement numbers CN202035283U and CN208370236U both use this kind of fixed spade to dig soil, which has the defects of large resistance and shallow digging depth.

[0004] Therefore, it is necessary to develop a chain type dig medicine machine aiming at the above defects. UTILITY MODEL CONTENTS
