Axial flow threshing rolling tube applied to harvesting machine

The utility model relates to an axial flow threshing rolling tube applied to a harvesting machine. An ultra-long rolling tube being 1.85m is adopted, in such an arrangement structure, the back end of the rolling tube has an upward tilting angle being 2 degrees through being compared with the front end, and a threshing rod is fixedly arranged on a frame disc through a threshing rod installing seat. The axial flow threshing rolling tube has the advantages that the structure is simple, the regulation can be carried out according to different growth conditions and types of crops, the axial flow threshing rolling tube is applicable to various operation conditions, in addition, the separation efficiency is high, and high cost performance is realized.
