| 摘 要： | 在自制的秸秆切碎试验台上对麦秸受切特性进行了试验研究。得出粉碎刀片在不同切割速度下，对短秆、长秆、秸秆不同切割部位、秸秆不同含水率、不同刀刃厚度、有定刀和无定刀等情况下的切断率曲线。根据试验结果可知除切割速度外，秸秆含水率和有无定刀是影响切断率的主要因素，在有定刀情况下切断湿秸秆需要40 m/s的切割线速度。

| Abstract: | An experiment was conducted on a self-made test equipment to test the chopping properties of wheat straw under different conditions. On the basis of testing results, main cutting curves of wheat straw were given, under different cutting speeds of rotatory blade with different straw lengths, moisture centents cutting positions, different thicks knife edge, with and without shear bar. The curves showed that the moisture contents of straw and the shear bar are main impact factors to the cutting ratio besides cutting speed. The speed of 40m/s is necessary to cut off wet straw. |
