Technical Field

[0001] The invention relates to the technical field of picking machinery, in particular to a multi-degree-of-freedom adjustment device for a picking roller brush of a dry safflower harvester. Background Art

[0002] Safflower likes warmth, is drought-tolerant and afraid of waterlogging, has a short growth cycle, is highly adaptable to the environment, is easy to cultivate, and has a wide range of uses. There are two types of dry safflower planting: irrigated land planting and dry land planting. The main varieties include Yumin Thornless Safflower, New Safflower No. 2, New Safflower No. 4, New Safflower No. 6, Jixuan No. 3, etc. The physical properties of safflower (such as plant height, width, fruit ball diameter, number, etc.) are significantly affected by planting patterns and varieties. The diversity of these physical properties makes it difficult for a single dry safflower harvester to adapt to the harvesting requirements of multiple varieties.

[0003] Therefore, designing a special device that can adapt to the efficient harvesting of dried safflower filaments of different varieties is an urgent problem that technicians in this field need to solve. Summary of the invention

[0004] In view of this, the present invention provides a multi-degree-of-freedom adjustment device for a picking roller brush of a dry safflower harvester, which can realize the harvesting of multiple varieties of dry safflower silks and improve the applicability of the machine.
