【摘要】：针对青饲料切碎机存在的生产率低、能耗大的问题,以9Z-6A型盘刀式青饲料切碎机为对象,对其切碎器进行了改进设计和性能试验研究。在原机喂入口增加一把定刀,使切碎器处于双定刀切割工况。改进前后切碎器切割性能对比试验表明:额定工况下,玉米秸秆含水率为9.74%时,双定刀比单定刀的切割质量得到明显改善,功耗降低21.8%,度电产量提高了6.72%,生产率提高了4.38%;同时,获得了双定刀工作时切割速度对切碎器性能的影响规律,得到了切割性能最佳时的切割速度。
[Abstract]:Aiming at the problems of low productivity and high energy consumption in the green feed cutter, the 9Z-6A disc cutter was used as the object. The improved design and performance test of the shredder were carried out. A fixed cutter was added to the feed inlet of the original machine. The cutting performance of the shredder before and after the improvement is compared with that of the two cutting tools. The results show that under rated conditions, the moisture content of corn straw is 9.74. The cutting quality of double fixed knife is obviously improved than that of single fixed knife, the power consumption is reduced by 21.8. the power output is increased by 6.72and the productivity is increased by 4.38. At the same time, the influence of cutting speed on the performance of the shredder is obtained, and the cutting speed when the cutting performance is optimal is obtained.
