Adjustable lateral axial flow cylinder with spiral feeding blade

The utility model relates to an adjustable horizontal axial-flow threshing cylinder of harvesting machinery, which comprises a closed type amplitude drum, a spiral feeding blade, an open type rod tooth cylinder with a toothed bar and a cylinder shaft, wherein the feeding section of the threshing cylinder adopts the closed type amplitude drum, and the rest part of the threshing cylinder adopts the open type rod tooth cylinder with the toothed bar; the spiral feeding blade is welded to the closed type amplitude drum; the open type rod tooth cylinder with the toothed bar comprises a spoke plate, a plurality of ear rings arranged on the outer edge of the spoke plate, toothed bars welded to the ear rings and rod teeth welded to the toothed bars; and the cylinder shaft, the open type rod tooth cylinder with the toothed bar and the amplitude drum are connected into a whole through hubs. The utility model can effectively solve the problems that the threshing rate and the hulling rate cannot be well guaranteed, the handling capacity of the threshing and separating device for the prior popularized combine harvester can not be matched with the high yield and the large discharge, and the feeding of the crops with green stems and flourishing leaves is not smooth and easy to be blocked under the condition of large discharge; and the utility model has smooth process flow, good threshing effect and reliable running.
