Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a self-propelled deep tillage excavator for root and tuber crops. Background Art

[0002] When rhizome crops mature, they are buried deep in the soil. These rhizome crops are fragile and easy to break, which makes it extremely difficult to harvest them in time. In addition, they are generally harvested by traditional manual labor, which is not only labor-intensive but also extremely inefficient. When harvesting rhizome crops such as Codonopsis pilosula, a lot of manpower and time are required, which can easily lead to a long harvest period, causing the crops to be damaged in the field and causing significant losses. At present, most machines can only harvest a specific rhizome crop. They have a single structure and can only perform harvesting operations. They cannot deep plow or dig the land, which increases the subsequent planting process and affects the farming efficiency.

[0003] To this end, the utility model provides a self-propelled root crop deep tillage excavator, which can perform deep tillage and soil digging operations while harvesting root crops, thereby improving farming efficiency. Summary of the invention
