　　工作原理

　　當螺旋(xuan)(xuan)(xuan)軸(zhou)(zhou)轉(zhuan)(zhuan)動(dong)(dong)時(shi)，由于物(wu)(wu)料(liao)的(de)(de)重力(li)及其與(yu)槽體壁(bi)所產生(sheng)的(de)(de)摩(mo)擦力(li)，使物(wu)(wu)料(liao)只(zhi)能(neng)(neng)在葉(xie)片(pian)的(de)(de)推(tui)送(song)(song)(song)(song)(song)下沿著(zhu)(zhu)輸(shu)送(song)(song)(song)(song)(song)機的(de)(de)槽底向(xiang)前(qian)移(yi)(yi)動(dong)(dong)，其情況好(hao)像不能(neng)(neng)旋(xuan)(xuan)(xuan)轉(zhuan)(zhuan)的(de)(de)螺母沿著(zhu)(zhu)旋(xuan)(xuan)(xuan)轉(zhuan)(zhuan)的(de)(de)螺桿作平(ping)移(yi)(yi)運動(dong)(dong)一樣。物(wu)(wu)料(liao)在中間軸(zhou)(zhou)承(cheng)(cheng)的(de)(de)運移(yi)(yi)，則是依靠后(hou)面前(qian)進著(zhu)(zhu)的(de)(de)物(wu)(wu)料(liao)的(de)(de)推(tui)力(li)。所以，物(wu)(wu)料(liao)在輸(shu)送(song)(song)(song)(song)(song)機中的(de)(de)運送(song)(song)(song)(song)(song)，完全是一種滑移(yi)(yi)運動(dong)(dong)。為了使螺旋(xuan)(xuan)(xuan)軸(zhou)(zhou)處于較為有利的(de)(de)受拉(la)狀態，一般都將(jiang)驅動(dong)(dong)裝置和卸料(liao)口(kou)安(an)放在輸(shu)送(song)(song)(song)(song)(song)機的(de)(de)同一端，而把(ba)進料(liao)口(kou)盡量放在另一端的(de)(de)尾部(bu)附(fu)近。旋(xuan)(xuan)(xuan)轉(zhuan)(zhuan)的(de)(de)螺旋(xuan)(xuan)(xuan)葉(xie)片(pian)將(jiang)物(wu)(wu)料(liao)推(tui)移(yi)(yi)而進行輸(shu)送(song)(song)(song)(song)(song)，使物(wu)(wu)料(liao)不與(yu)螺旋(xuan)(xuan)(xuan)輸(shu)送(song)(song)(song)(song)(song)機葉(xie)片(pian)一起旋(xuan)(xuan)(xuan)轉(zhuan)(zhuan)的(de)(de)力(li)是物(wu)(wu)料(liao)自(zi)身重量和螺旋(xuan)(xuan)(xuan)輸(shu)送(song)(song)(song)(song)(song)機機殼對物(wu)(wu)料(liao)的(de)(de)摩(mo)擦阻力(li)。葉(xie)片(pian)的(de)(de)面型根據輸(shu)送(song)(song)(song)(song)(song)物(wu)(wu)料(liao)的(de)(de)不同有實體面型、帶式面型、葉(xie)片(pian)面型等(deng)型式。螺旋(xuan)(xuan)(xuan)輸(shu)送(song)(song)(song)(song)(song)機的(de)(de)螺旋(xuan)(xuan)(xuan)軸(zhou)(zhou)在物(wu)(wu)料(liao)運動(dong)(dong)方向(xiang)的(de)(de)終端有止(zhi)推(tui)軸(zhou)(zhou)承(cheng)(cheng)以隨物(wu)(wu)料(liao)給(gei)螺旋(xuan)(xuan)(xuan)的(de)(de)軸(zhou)(zhou)向(xiang)反力(li)，在機長較長時(shi)，應(ying)加中間吊掛軸(zhou)(zhou)承(cheng)(cheng)。
