二、秸稈壓塊機工作原理
壓塊機工作時，物料通過喂料鬥及喂入螺旋機構的輸送，被均勻、連lian續xu地di喂wei入ru環huan模mo與yu壓ya輥gun之zhi間jian的de腔qiang體ti中zhong，由you環huan模mo與yu壓ya輥gun的de相xiang對dui運yun動dong把ba物wu料liao逐zhu漸jian帶dai入ru環huan模mo與yu壓ya輥gun的de楔xie形xing間jian隙xi中zhong，隨sui壓ya縮suo力li的de增zeng大da，物wu料liao間jian聯lian結jie力li增zeng強qiang被bei擠ji入ru環huan模mo孔kong內nei，當dang壓ya縮suo力li增zeng大da到dao能neng克ke服fu模mo孔kong對dui物wu料liao的de摩mo擦ca阻zu力li時shi，不bu斷duan從cong環huan模mo孔kong中zhong呈cheng條tiao狀zhuang擠ji出chu。壓ya出chu時shi物wu料liao被bei機ji體ti外wai殼ke上shang的de切qie片pian切qie成cheng長chang度du適shi宜yi的de草cao塊kuai，壓ya塊kuai機ji工gong作zuo原yuan理li如ru下xia圖tu2所示
