玉米秸秆粉碎装置结构、运动参数对粉碎性能的影响

Impact of Corn Straw Millstone's Structure and Motion Parameters on Crushing Capability

玉米秸秆粉碎装置的功耗过大是实现玉米联合收获机小型化的瓶颈。试验表明:合理选用动刀、定刀、包角等参数的组合,可以显著降低功耗;直刀式动刀配切碎定刀喂入性能较好,在较低速度时就能达到较高的合格率,功耗也相对较低。

The deficient in spending too much power on corn straw millstone is the bottle-neck in realization of miniaturization for a combine harvester for the corn .The results from the experiments indicated that rational choosing the combination of parameters of moved reamer,fixed reamer and bundle angles could remarkably reduce the power.The vertical moved reamer matching cutting fixed reamer had a better feeding ability and could get a higher crushing ratio and expend lower power.
