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。
In the homemade straw chopping test stand on the cutting characteristics of wheat were studied. The results showed that the cutoff rate curves of shredded blades under different cutting speeds were different for different cutting positions of short stalks, long stalks, stalks, different moisture contents of straw, different blade thicknesses, fixed knives and no fixed knives. According to the test results, except for the cutting speed, the moisture content of straw and the presence or absence of fixed knife are the main factors affecting the cutting rate. Cutting speed of 40 m / s is required to cut the wet straw with the fixed knife.
