在封閉的(de)(de)機殼內借運(yun)動(dong)著的(de)(de)鏈條刮(gua)(gua)板(ban)與煤的(de)(de)摩擦將煤連續輸(shu)(shu)出，鏈條刮(gua)(gua)板(ban)在運(yun)行時(shi)埋(mai)于被(bei)輸(shu)(shu)送(song)(song)(song)的(de)(de)煤中(zhong)固接在牽引鏈上的(de)(de)刮(gua)(gua)板(ban)在封閉的(de)(de)料(liao)(liao)槽(cao)(cao)(cao)中(zhong)輸(shu)(shu)送(song)(song)(song)散狀物(wu)料(liao)(liao)的(de)(de)輸(shu)(shu)送(song)(song)(song)機。這種(zhong)輸(shu)(shu)送(song)(song)(song)機的(de)(de)牽引鏈和(he)刮(gua)(gua)板(ban)都埋(mai)入(ru)物(wu)料(liao)(liao)中(zhong)，刮(gua)(gua)板(ban)只占(zhan)料(liao)(liao)槽(cao)(cao)(cao)的(de)(de)一(yi)(yi)部分斷(duan)面(mian)，物(wu)料(liao)(liao)占(zhan)料(liao)(liao)槽(cao)(cao)(cao)的(de)(de)大部分斷(duan)面(mian)。它能水平、傾斜(xie)或垂直輸(shu)(shu)送(song)(song)(song)物(wu)料(liao)(liao)。水平輸(shu)(shu)送(song)(song)(song)時(shi)，所用(yong)刮(gua)(gua)板(ban)為平條形，利用(yong)埋(mai)入(ru)散料(liao)(liao)的(de)(de)鏈條和(he)刮(gua)(gua)板(ban)對散料(liao)(liao)層的(de)(de)切割(ge)力大于槽(cao)(cao)(cao)壁對散料(liao)(liao)阻力的(de)(de)原理，使散料(liao)(liao)隨刮(gua)(gua)板(ban)一(yi)(yi)起(qi)向前移動(dong)，此時(shi)移動(dong)的(de)(de)料(liao)(liao)層高度與槽(cao)(cao)(cao)寬之比在一(yi)(yi)定的(de)(de)比值(zhi)范圍之內，物(wu)料(liao)(liao)流(liu)是穩定的(de)(de)。
（1）埋刮(gua)板(ban)輸(shu)送(song)機(ji)在水平輸(shu)送(song)時，物(wu)料(liao)(liao)受到刮(gua)板(ban)鏈(lian)條在運動方(fang)向的(de)壓力及物(wu)料(liao)(liao)自(zi)身(shen)重量的(de)作(zuo)用，在物(wu)料(liao)(liao)間(jian)產(chan)生了內摩擦力。這種摩擦力保證了料(liao)(liao)層之間(jian)的(de)穩定(ding)狀態，并足以克服(fu)物(wu)料(liao)(liao)在機(ji)槽中移動而產(chan)生的(de)外摩擦力，使物(wu)料(liao)(liao)形成連續(xu)整(zheng)體的(de)料(liao)(liao)流而被輸(shu)送(song)。
（2）埋刮板輸送機在垂直提(ti)升(sheng)(sheng)時，物(wu)(wu)(wu)(wu)料(liao)(liao)受(shou)到刮板鏈(lian)條(tiao)在運(yun)動方(fang)向的(de)壓力(li)，在物(wu)(wu)(wu)(wu)料(liao)(liao)中產(chan)生了(le)橫方(fang)向的(de)側面壓力(li)，形(xing)成(cheng)了(le)物(wu)(wu)(wu)(wu)料(liao)(liao)的(de)內(nei)摩(mo)擦(ca)(ca)力(li)。同時由于下(xia)水平(ping)段的(de)不斷給料(liao)(liao)，下(xia)部物(wu)(wu)(wu)(wu)料(liao)(liao)相繼對上部物(wu)(wu)(wu)(wu)料(liao)(liao)產(chan)生推(tui)移力(li)。這種摩(mo)擦(ca)(ca)力(li)和推(tui)移力(li)足(zu)以克服物(wu)(wu)(wu)(wu)料(liao)(liao)在機槽中移動而(er)產(chan)生的(de)外摩(mo)擦(ca)(ca)阻力(li)和物(wu)(wu)(wu)(wu)料(liao)(liao)自(zi)身的(de)重量，使物(wu)(wu)(wu)(wu)料(liao)(liao)形(xing)成(cheng)了(le)連續整體的(de)料(liao)(liao)流而(er)被提(ti)升(sheng)(sheng)。
埋刮板輸(shu)送機的安(an)裝:
的安裝需要(yao)進行以下工作：
1)定位:首先定出機(ji)(ji)頭(tou)和機(ji)(ji)尾(wei)的位置，然后(hou)再(zai)定出刮板輸送機(ji)(ji)的中心(xin)線。2)鋪設中間槽:
根據(ju)定(ding)出(chu)的(de)(de)(de)輸(shu)送(song)(song)機(ji)(ji)中(zhong)心(xin)線(xian)(xian)，鋪設(she)中(zhong)間槽(cao)(cao)。如(ru)采用非金(jin)屬槽(cao)(cao)箱，則中(zhong)間槽(cao)(cao)鋪砌磚和水(shui)泥預(yu)制(zhi)板(ban)，再粘結(jie)鑄石(shi)襯板(ban)。鑄石(shi)襯板(ban)鋪設(she)時，要(yao)注意(yi)平(ping)(ping)直，接縫盡量少，縱(zong)向縫隙要(yao)錯(cuo)開(kai)(kai)，防(fang)止工作(zuo)時將縫隙磨成溝(gou)。輸(shu)送(song)(song)機(ji)(ji)表面鋪設(she)需要(yao)平(ping)(ping)直，如(ru)輸(shu)送(song)(song)機(ji)(ji)平(ping)(ping)面內有過大的(de)(de)(de)彎曲，勢必導致兩條(tiao)(tiao)(tiao)鏈(lian)(lian)(lian)(lian)受力不(bu)(bu)均勻，加速鏈(lian)(lian)(lian)(lian)子與(yu)(yu)槽(cao)(cao)壁鑄石(shi)之(zhi)間的(de)(de)(de)磨損，甚至(zhi)卡鏈(lian)(lian)(lian)(lian)。各段槽(cao)(cao)體搭接應平(ping)(ping)整無臺階。由(you)于槽(cao)(cao)體本身結(jie)構限制(zhi)，相鄰中(zhong)間槽(cao)(cao)在(zai)垂直方(fang)向偏轉(zhuan)不(bu)(bu)應過大。若輸(shu)送(song)(song)機(ji)(ji)鋪設(she)不(bu)(bu)平(ping)(ping)直，運輸(shu)功耗將會增加。機(ji)(ji)道上的(de)(de)(de)積煤或(huo)雜(za)物應掃除干(gan)凈。3)安裝(zhuang)機(ji)(ji)頭(tou)和機(ji)(ji)尾:機(ji)(ji)頭(tou)和機(ji)(ji)尾應留有一定(ding)空間，便于維護及檢(jian)修(xiu)。鏈(lian)(lian)(lian)(lian)輪中(zhong)心(xin)線(xian)(xian)要(yao)與(yu)(yu)輸(shu)送(song)(song)機(ji)(ji)中(zhong)心(xin)線(xian)(xian)垂直，并保(bao)證水(shui)平(ping)(ping)。4)裝(zhuang)刮板(ban)鏈(lian)(lian)(lian)(lian):刮板(ban)鏈(lian)(lian)(lian)(lian)在(zai)安裝(zhuang)前(qian)，應預(yu)先連接好，刮板(ban)均勻地(di)分布在(zai)鏈(lian)(lian)(lian)(lian)條(tiao)(tiao)(tiao)中(zhong)。如(ru)果是兩條(tiao)(tiao)(tiao)鏈(lian)(lian)(lian)(lian)條(tiao)(tiao)(tiao)，要(yao)選擇長度相等，或(huo)按(an)出(chu)廠(chang)時的(de)(de)(de)配對鏈(lian)(lian)(lian)(lian)條(tiao)(tiao)(tiao)組裝(zhuang)。鏈(lian)(lian)(lian)(lian)條(tiao)(tiao)(tiao)不(bu)(bu)得有扭(niu)轉(zhuan)現(xian)象(xiang)。圓環鏈(lian)(lian)(lian)(lian)焊縫邊朝上，防(fang)止鏈(lian)(lian)(lian)(lian)條(tiao)(tiao)(tiao)與(yu)(yu)鏈(lian)(lian)(lian)(lian)輪發生夾卡現(xian)象(xiang)。5)檢(jian)查(cha)和空運轉(zhuan):輸(shu)送(song)(song)機(ji)(ji)安裝(zhuang)好后，應進(jin)行全面檢(jian)查(cha)并開(kai)(kai)動(dong)輸(shu)送(song)(song)機(ji)(ji)。空運轉(zhuan)2h，主要(yao)檢(jian)查(cha)驅動(dong)裝(zhuang)置(zhi)和刮板(ban)運轉(zhuan)是否正常。同時，使各相鄰中(zhong)間槽(cao)(cao)靠緊，再次緊鏈(lian)(lian)(lian)(lian)，調節鏈(lian)(lian)(lian)(lian)條(tiao)(tiao)(tiao)長度。
刮板輸送(song)機(ji)(ji)(ji)工作的(de)(de)(de)最初兩(liang)周(zhou)內，應特別注意鏈(lian)(lian)(lian)條的(de)(de)(de)松緊程度。檢查的(de)(de)(de)方法是：如果機(ji)(ji)(ji)尾有(you)驅動(dong)(dong)裝(zhuang)置(zhi)，則(ze)點動(dong)(dong)該驅動(dong)(dong)裝(zhuang)置(zhi)，當(dang)機(ji)(ji)(ji)尾鏈(lian)(lian)(lian)輪的(de)(de)(de)上股(gu)(gu)鏈(lian)(lian)(lian)條有(you)兩(liang)個以(yi)上完全(quan)松弛的(de)(de)(de)鏈(lian)(lian)(lian)環時(shi)，需(xu)緊鏈(lian)(lian)(lian)或(huo)拆(chai)鏈(lian)(lian)(lian)減環，減小鏈(lian)(lian)(lian)環長(chang)度。如果僅有(you)機(ji)(ji)(ji)頭驅動(dong)(dong)裝(zhuang)置(zhi)，則(ze)需(xu)要將電機(ji)(ji)(ji)反轉點動(dong)(dong)，當(dang)機(ji)(ji)(ji)頭鏈(lian)(lian)(lian)輪處的(de)(de)(de)上股(gu)(gu)鏈(lian)(lian)(lian)條有(you)兩(liang)個以(yi)上完全(quan)松弛的(de)(de)(de)鏈(lian)(lian)(lian)環時(shi)。同樣需(xu)要緊鏈(lian)(lian)(lian)或(huo)拆(chai)鏈(lian)(lian)(lian)減環。
埋(mai)(mai)刮板(ban)輸送(song)(song)機主要分以下種(zhong)類:1、水平型(xing)埋(mai)(mai)刮板(ban)輸送(song)(song)機 2、垂直(zhi)型(xing)埋(mai)(mai)刮板(ban)輸送(song)(song)機 3、Z型(xing)埋(mai)(mai)刮板(ban)輸送(song)(song)機
