Abstract: The harvesting operation of Fritillaria Ussuriensis is a key link in Fritillaria Ussuriensis planting in forest area, which has an important impact on the color and medicinal value of Fritillaria Ussuriensis. The existing harvesting equipment has gradually exposed the problems of low operation efficiency and poor environmental adaptability. As the core part of fritillaria flat harvester, the digging shovel directly affects the quality of harvesting operation, but the existing digging shovel still has some problems, such as simple structure design and semiempirical research idea. In order to develop the harvesting equipment of Fritillaria Ussuriensis that can meet the needs of the industry, combined with the existing planting conditions and technological development, the whole analysis of root crop harvester at home and abroad was carried out, and the idea of developing a small selfwalking combined harvester that can harvest other crops was put forward. In terms of harvester and the development of digging shovel carried on the thorough analysis, proposed the development direction of fritillary bulb harvester for efficiency, specialization, harvest crops, collecting process compatibility, terms of the development direction of digging shovel means for scientific research ideas, research and development professional, performance stabilization, in order to boost the process of fully mechanized fritillaria industry.
