Abstract

The invention relates to a threshing cylinder for a cereal combined harvester. The threshing cylinder comprises a spiral feeding head, a threshing cylinder body and a spiral impurity discharging tail,wherein the spiral feeding head comprises feeding spiral blades, feeding spiral blade supporting plates and a conical cylinder; the threshing cylinder body comprises a roller shaft, range disks, a roller frame, threshing spike teeth and rubber caps; the spiral impurity discharging tail comprises discharging spiral blades, discharging spiral blade supporting plates and a circular cylinder; the spiral feeding head is welded to the left side of the threshing cylinder body, and the spiral impurity discharging tail is welded to the right side of the threshing cylinder body; and the spiral feedinghead, the spiral impurity discharging tail and the threshing cylinder body are coaxial. According to the threshing cylinder for the cereal combined harvester disclosed by the invention, the feeding device is solid, the feeding effect is good, the threshing resistance is low, time is long, threshing is sufficient, the threshing performance is improved, the reduction rate is reduced, and the threshing efficiency is improved.

Description

technical field [0001] The invention belongs to the field of agricultural machinery and equipment, and in particular relates to a grain combine harvester threshing drum, which is used for grain threshing and separation. Background technique [0002] Most of the feeding helical blades on the existing conical cylinder have two ends, and the feeding is uneven, causing the crops to stay at the connection between the bridge and the threshing chamber, and the feeding effect is poor; the feeding part of the existing longitudinal axial flow threshing drum The helical blade is directly welded to the conical cylinder of the base body. When the drum rotates at high speed or the feeding volume is large, the feeding helical blade is subjected to a large force and is easy to break. Shutdown for maintenance affects work efficiency. [0003] Such as the products of well-known enterprises such as Yanmar and Kubota, the threshing drums are mostly installed horizontally, and the crops in the t...
