通过脱粒栅型和振动脱粒机构成的振动脱粒槽、谐振弹簧、缓冲弹簧、减速齿轮等部件，将发动机的旋转动能转换成小角度搓动式振动，并作用于农作物穗，实现对多种农作物的有效脱粒。具有较高的脱粒净度，与传统滚筒式脱粒机相比，除具有同样野外移动作业性能外，更具有能耗低（ The rotary kinetic energy of the engine is converted into small-angle twisting vibration through the vibration threshing groove, the resonant spring, the buffer spring, the reduction gear and other components by the threshing grate and the vibration thresher, and acts on the spike of the crop to achieve the effect of various crops Effective threshing. With a high degree of threshing clarity, compared with the traditional drum thresher, in addition to the same field mobile work performance, but also has low energy consumption
