Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery technology, and in particular relates to a thresher. Background Technology

[0002] The threshing drum and cleaning system of the threshing machine are designed with a direct transition. The material discharged from the drum is prone to uneven loading and distribution, resulting in material accumulation on one side of the cleaning screen and sparse material on the other side. This causes screen blockage, high grain loss rate, and insufficient grain cleanliness, which seriously affects the operating efficiency.

[0003] In existing technologies, small- and medium-capacity threshers weld unequal-spaced diversion grids below the drum to replace traditional straight guide plates, reducing material buildup in the middle. For large-capacity grain harvesters, a bidirectional conveying auger is added below the drum, with the auger blades arranged in opposite directions to forcefully push the material to both sides. The unequal-spaced diversion grids are a fixed structure and cannot adapt to varying working conditions such as wet grain. The bidirectional auger forced uniform distribution solution requires an additional transmission mechanism, resulting in a large modification volume and high cost. Summary of the Invention
