  ne斗式(shi)提(ti)升(sheng)機-板(ban)鏈提(ti)升(sheng)機-重(zhong)型板(ban)鏈提(ti)升(sheng)機(斗式(shi)提(ti)升(sheng)機ne30)
ne斗式提(ti)升機將固(gu)定(ding)殼體(ti)(ti)(ti)插入(ru)活(huo)動(dong)(dong)體(ti)(ti)(ti)內并通過螺(luo)栓連接安裝在(zai)支架上(shang);同(tong)時(shi)在(zai)固(gu)定(ding)殼體(ti)(ti)(ti)與(yu)活(huo)動(dong)(dong)體(ti)(ti)(ti)之間壓(ya)上(shang)厚發泡橡膠，起(qi)到(dao)緊(jin)貼密封作用(yong);改向滾筒、從(cong)(cong)動(dong)(dong)軸和(he)軸承(cheng)(cheng)座固(gu)定(ding)在(zai)活(huo)動(dong)(dong)體(ti)(ti)(ti)上(shang)。調節時(shi)由(you)液壓(ya)缸帶(dai)動(dong)(dong)活(huo)動(dong)(dong)體(ti)(ti)(ti)，活(huo)動(dong)(dong)體(ti)(ti)(ti)通過軸承(cheng)(cheng)座帶(dai)動(dong)(dong)改向滾筒和(he)從(cong)(cong)動(dong)(dong)軸繼而調整鏈條(tiao)或備斗帶(dai)的(de)張(zhang)緊(jin)力。由(you)于軸承(cheng)(cheng)座是在(zai)活(huo)動(dong)(dong)體(ti)(ti)(ti)上(shang)固(gu)定(ding)的(de)，沒有開(kai)長(chang)孔，所以就避免了在(zai)運行(xing)過程中冒灰。在(zai)活(huo)動(dong)(dong)體(ti)(ti)(ti)底部設(she)有一對對開(kai)弧(hu)(hu)形(xing)清(qing)掃(sao)門(men)(men)。當發生堵(du)料或停機檢(jian)修時(shi)打開(kai)弧(hu)(hu)形(xing)清(qing)理門(men)(men)，物料自行(xing)下落，及時(shi)清(qing)理殼體(ti)(ti)(ti)內的(de)積料，避免了物料長(chang)期堆積腐爛變質(zhi)影響物料質(zhi)量和(he)腐蝕提(ti)升機殼體(ti)(ti)(ti)，同(tong)時(shi)減輕工(gong)人(ren)勞動(dong)(dong)強度，提(ti)升工(gong)作效率(lv)。
