Threshing part feeding spiral structure

The utility model discloses a feeding spiral structure of a threshing part, and relates to the technical field of harvesters. According to the technical scheme, the threshing device is characterized by comprising a threshing cylinder, three to six spiral blades are arranged on the outer side wall of the threshing cylinder, and the multiple spiral blades are evenly distributed in the circumferential direction. The carrying and conveying capacity is enhanced by increasing the number of the spiral blades, so that the blocking problem of the conveying part can be relieved, crops can enter the threshing part more uniformly and smoothly, the working load of the machine is reduced, the threshing performance is improved, and the whole-feeding combine harvester has the advantages that the feeding amount is increased, and the working efficiency is improved. And the working performance of the machine is also ensured. 本实用新型公开了一种脱粒部喂入螺旋结构，其涉及收割机技术领域。其技术方案要点包括脱粒筒，所述脱粒筒外侧壁设置有螺旋叶片，所述螺旋叶片的数量为3～6个，且多个所述螺旋叶片沿周向均布设置。本实用新型通过增加螺旋叶
