摘要：为满足软质秸秆和硬质高纤维物料规模化粉碎的生产需要,并克服单一切碎机、粉碎机的缺点,设计了一种带风引出料装置的切粉一体化组合式秸秆粉碎机,实现了硬质高纤维秸秆的强制喂入。结果表明,软质秸秆可直接通过粉碎装置喂料口喂入,无需切碎,平均生产率为1.27 kg/h,吨料电耗为32.0 kW·h;硬质高纤维秸秆需通过带有强制喂料辊的切碎装置后进行先切后粉,平均生产率为0.67 kg·h,吨料电耗为60.5 kW·h。该机器具有性能稳定、安全可靠、物料适应性强和操作环境无粉尘等优点,性能满足设计要求。

摘要：To meet the large-scale smashing production of soft straw and hard straw with high fiber materials and overcome the shortcomings of single-mission cutter and shredder, a straw grinder with air-induced discharging device was developed, which realized the force feeding of hard straws with high fiber. The results showed that soft straw could be directly fed into the smashing device without cutting with the average efficiency of 1.27 kg/h and electricity consumption o per ton of 32.0 k W·*** hard straw with high fiber should be first fed into the shredding device with force feeding roll to cut and then grinded, for which the efficiency average was 0.67kg/h and electricity consumption per ton was 60.5 k W·h. The machine was stable,safe and reliable with strong adaptability of materials and no-dust operating environment, which satisfied the design requirements.
