埋刮(gua)(gua)板(ban)(ban)輸(shu)送(song)(song)(song)機(ji)(ji)是輸(shu)送(song)(song)(song)粉(fen)塵(chen)狀、小顆粒及(ji)小塊狀等埋刮(gua)(gua)板(ban)(ban)輸(shu)送(song)(song)(song)機(ji)(ji)運輸(shu)設備，可以水平、傾(qing)斜輸(shu)送(song)(song)(song)，輸(shu)送(song)(song)(song)物(wu)料(liao)時，刮(gua)(gua)板(ban)(ban)鏈(lian)條全埋在物(wu)料(liao)之中(zhong)。埋刮(gua)(gua)板(ban)(ban)輸(shu)送(song)(song)(song)機(ji)(ji)具有結構(gou)簡單，使用，造(zao)價(jia)低廉，輸(shu)送(song)(song)(song)距離(li)長(chang)，并能輸(shu)送(song)(song)(song)灼熱物(wu)料(liao)等優(you)點。

埋刮板輸送機工作原理：

埋(mai)刮板輸(shu)送機在(zai)水平(ping)輸(shu)送時，物(wu)料(liao)(liao)受到刮板鏈條在(zai)運(yun)動(dong)方向的壓力及物(wu)料(liao)(liao)自身重量(liang)的作用(yong)，在(zai)物(wu)料(liao)(liao)間產生(sheng)了(le)內摩(mo)擦(ca)力。這種摩(mo)擦(ca)力了(le)料(liao)(liao)層之間的穩定狀態，并足以克(ke)服物(wu)料(liao)(liao)在(zai)機槽(cao)中移(yi)動(dong)而產生(sheng)的外摩(mo)擦(ca)力，使物(wu)料(liao)(liao)形成(cheng)連續整體的料(liao)(liao)流而被輸(shu)送。

埋刮板輸送(song)機(ji)技術特點：

1、用(yong)單條礦用(yong)圓(yuan)環鏈拖動刮(gua)板，并選(xuan)用(yong)凹齒(chi)型鏈輪進行驅動，具有負荷能力大，鏈條壽命長(chang)和(he)的特點(dian)。

2、鏈條能(neng)自(zi)動(dong)張緊(jin)(jin)，可鏈條在長時(shi)間內始終處于適(shi)度張緊(jin)(jin)狀(zhuang)態下(xia)運行，省(sheng)去人工及時(shi)而頻(pin)繁的(de)緊(jin)(jin)張操作。

3、鏈(lian)(lian)(lian)條(tiao)和(he)刮板(ban)回(hui)程(cheng)段由托(tuo)(tuo)輪(lun)支(zhi)承(cheng)運行，不僅(jin)省(sheng)力減(jian)磨，而(er)且通過(guo)回(hui)鏈(lian)(lian)(lian)若干(gan)托(tuo)(tuo)輪(lun)間撓度的自動(dong)(dong)變化，有(you)助于鏈(lian)(lian)(lian)條(tiao)的自動(dong)(dong)漲(zhang)緊及(ji)滑(hua)行。

4、如(ru)驅動機(ji)(ji)構背(bei)負(fu)在機(ji)(ji)頭(tou)上部與機(ji)(ji)殼自(zi)成一體(ti)(ti)，可(ke)(ke)使整體(ti)(ti)安(an)裝不(bu)需用(yong)地腳螺栓即可(ke)(ke)就(jiu)地自(zi)由放置(zhi)而運行(xing)。

5、運行速(su)度可采用YVP系列(lie)電機和變頻器組(zu)合(he)控制，是   上(shang)調(diao)速(su)方式。

6、進料方式采用(yong)兩側大(da)(da)尺寸通過分(fen)流進入(ru)，使回程鏈條(tiao)及刮(gua)板(ban)與進料隔離，并以不變的大(da)(da)尺寸料層厚度向前輸送。使鏈條(tiao)及刮(gua)板(ban)回帶(dai)物(wu)料的現(xian)象(xiang)不再發(fa)生。

埋(mai)刮板輸送機(ji)廣泛應用于建材(cai)、化工、冶金、煤(mei)炭、礦(kuang)山、機(ji)械等部門(men)。

埋(mai)刮(gua)板輸(shu)(shu)送(song)(song)機，結構簡單，重量(liang)輕，體積小(xiao)，密閉性好(hao)，安裝維修(xiu)比(bi)較(jiao)方(fang)便；工(gong)(gong)藝布(bu)置較(jiao)為(wei)靈活，既可(ke)水平輸(shu)(shu)送(song)(song)，又能(neng)傾斜或垂直輸(shu)(shu)送(song)(song)，還可(ke)多點(dian)加料(liao)和卸(xie)料(liao)；由于(yu)殼體是密閉的，因(yin)此在(zai)輸(shu)(shu)送(song)(song)物料(liao)過程中，對防治環境污染等方(fang)面具有突出的特點(dian)，在(zai)糧油加工(gong)(gong)工(gong)(gong)藝中廣泛的應(ying)用(yong)。

刮板(ban)(ban)鏈條是埋刮板(ban)(ban)輸送機中主要的(de)工作部件之(zhi)一。埋刮板(ban)(ban)輸送機的(de)各(ge)種故障都與刮板(ban)(ban)鏈條的(de)運行(xing)狀(zhuang)態有(you)關，因此，物(wu)料(liao)的(de)輸送效果(guo)與刮板(ban)(ban)鏈條結構型式(shi)的(de)選擇(ze)有(you)較大的(de)關系。在(zai)糧(liang)油加工過(guo)程中，常采用埋刮板(ban)(ban)輸送機來連續輸送顆(ke)粒散(san)狀(zhuang)的(de)物(wu)料(liao)，其輸送方式(shi)有(you)水平，傾斜和(he)垂直等型式(shi)。刮板(ban)(ban)鏈條是埋刮板(ban)(ban)輸送機的(de)承載(zai)牽引構件。

由于埋(mai)刮板(ban)輸送(song)鏈(lian)條(tiao)在被(bei)輸送(song)的物料中拖動，因此要防止被(bei)輸送(song)物料將鏈(lian)條(tiao)及應(ying)回轉的零(ling)件擠死。叉型鏈(lian)的特點是(shi)鉸鏈(lian)處在鏈(lian)桿叉頭部位(wei)的內部間隙大，又沒(mei)有滾子，故進入鉸鏈(lian)的物料容易排

除，是專(zhuan)門(men)提供給埋刮板(ban)輸送(song)機使用的(de)輸送(song)鏈條。

叉(cha)型鏈(lian)由(you)(you)只(zhi)起到牽引作用(yong)(yong)的(de)基(ji)本鏈(lian)接與(yu)完(wan)成刮(gua)(gua)(gua)送(song)(song)(song)(song)作業的(de)刮(gua)(gua)(gua)板(ban)(ban)(ban)組(zu)成，也(ye)稱之為刮(gua)(gua)(gua)板(ban)(ban)(ban)鏈(lian)條。根據完(wan)成刮(gua)(gua)(gua)送(song)(song)(song)(song)作業的(de)刮(gua)(gua)(gua)板(ban)(ban)(ban)不(bu)同，其(qi)結構形(xing)式分(fen)為T形(xing)、V形(xing)、U形(xing)和(he)H形(xing)。埋刮(gua)(gua)(gua)板(ban)(ban)(ban)輸(shu)(shu)送(song)(song)(song)(song)機用(yong)(yong)叉(cha)型鏈(lian)在(zai)(zai)埋刮(gua)(gua)(gua)板(ban)(ban)(ban)輸(shu)(shu)送(song)(song)(song)(song)行業廣泛應(ying)用(yong)(yong)。埋刮(gua)(gua)(gua)板(ban)(ban)(ban)輸(shu)(shu)送(song)(song)(song)(song)機在(zai)(zai)水平輸(shu)(shu)送(song)(song)(song)(song)時，物(wu)料(liao)(liao)(liao)受到刮(gua)(gua)(gua)板(ban)(ban)(ban)鏈(lian)條在(zai)(zai)運行方向(xiang)上的(de)推力(li)及自(zi)身的(de)重力(li)的(de)作用(yong)(yong)，物(wu)料(liao)(liao)(liao)層之間產(chan)生了內摩(mo)(mo)(mo)擦(ca)力(li)。當這(zhe)種內摩(mo)(mo)(mo)擦(ca)力(li)足以克(ke)服(fu)物(wu)料(liao)(liao)(liao)與(yu)槽(cao)壁間的(de)外摩(mo)(mo)(mo)擦(ca)力(li)時，物(wu)料(liao)(liao)(liao)就隨(sui)同刮(gua)(gua)(gua)板(ban)(ban)(ban)鏈(lian)條形(xing)成連續整體的(de)物(wu)料(liao)(liao)(liao)流而(er)被輸(shu)(shu)送(song)(song)(song)(song)。在(zai)(zai)垂直(zhi)輸(shu)(shu)送(song)(song)(song)(song)時，物(wu)料(liao)(liao)(liao)受到刮(gua)(gua)(gua)板(ban)(ban)(ban)鏈(lian)條在(zai)(zai)運行方向(xiang)上的(de)推力(li)。當由(you)(you)于橫向(xiang)側壓力(li)而(er)產(chan)生的(de)內摩(mo)(mo)(mo)擦(ca)力(li)及下(xia)部(bu)不(bu)斷給(gei)料(liao)(liao)(liao)所(suo)產(chan)生的(de)對上部(bu)物(wu)料(liao)(liao)(liao)的(de)推移力(li)，大于物(wu)料(liao)(liao)(liao)與(yu)槽(cao)壁間的(de)外摩(mo)(mo)(mo)擦(ca)力(li)和(he)物(wu)料(liao)(liao)(liao)的(de)重力(li)時，物(wu)料(liao)(liao)(liao)就隨(sui)著(zhu)刮(gua)(gua)(gua)板(ban)(ban)(ban)鏈(lian)條形(xing)成連續的(de)物(wu)料(liao)(liao)(liao)流而(er)向(xiang)上輸(shu)(shu)送(song)(song)(song)(song)。

糧油加工工藝(yi)(yi)中(zhong)，常見的埋刮板輸(shu)(shu)送(song)(song)(song)機多為(wei)MS型(xing)(xing)水(shui)平輸(shu)(shu)送(song)(song)(song)、MC型(xing)(xing)垂直(zhi)輸(shu)(shu)送(song)(song)(song)、MZ型(xing)(xing)Z埋刮板輸(shu)(shu)送(song)(song)(song)3種。水(shui)平輸(shu)(shu)送(song)(song)(song)機一(yi)般傾(qing)角為(wei)0°～15°，如果輸(shu)(shu)送(song)(song)(song)是在物(wu)料(liao)(liao)充滿(man)機槽的情(qing)況下進行，即(ji)使(shi)傾(qing)角再大些，仍能物(wu)料(liao)(liao)連續不斷地(di)輸(shu)(shu)送(song)(song)(song)。垂直(zhi)輸(shu)(shu)送(song)(song)(song)機傾(qing)角為(wei)30°～90°。Z埋刮板輸(shu)(shu)送(song)(song)(song)機輸(shu)(shu)送(song)(song)(song)高度一(yi)般在20m左右，水(shui)平輸(shu)(shu)送(song)(song)(song)距離小于(yu)30m。同時，也使(shi)用一(yi)些垂直(zhi)環(huan)型(xing)(xing)刮板鏈條(tiao)輸(shu)(shu)送(song)(song)(song)，如油料(liao)(liao)加工工藝(yi)(yi)中(zhong)的環(huan)形(xing)浸出器和澄油箱(xiang)等，其(qi)目的主要是在輸(shu)(shu)送(song)(song)(song)物(wu)料(liao)(liao)時完成工藝(yi)(yi)過程。
