[0002] With the introduction of the country's land policy, the transfer of cultivated land is concentrated. The traditional grain combine harvester represented by "tangential flow + horizontal axial flow" is limited by its structure, and its feeding volume is no longer suitable for harvesting large plots. demand, in order to pursue high efficiency and high income, user needs turn to large and medium-sized longitudinal axial flow grain combine harvesters with high cost performance, and the core component of longitudinal axial flow grain combine harvesters is the threshing separation drum. The high performance and multi-functional threshing separation drum has become the key point for various businesses to compete for market share. At present, the threshing separation elements of the longitudinal axial flow drum on the market are mostly "plate teeth + nail teeth", "grain rod + threshing plate", More complex structures such as "striped rod + nail teeth", the reliability and versatility of use cannot meet the needs of users

[0003] The technical solution of the patent ZL200620086948.4 longitudinal axial flow drum solves the problem of the vertically arranged threshing drum suitable for large plots that needs to be solved in this technical solution, and does not need to replace the drum when harvesting different crops, so as to realize the multi-purpose problem of one machine, but The threshing element is a combination of spirally arranged stem holders. The stem holder is fixed on the support by the threshing plate and the stem head through fasteners. When harvesting different crops, it is necessary to replace the position of the threshing plate before and after the stem head. For this reason, after replacing the front and rear positions of the threshing plate, due to the difference in weight of the threshing plate parts, the original dynamic balance of the high-speed rotating threshing drum is destroyed.
