埋(mai)(mai)刮(gua)板輸(shu)(shu)(shu)送(song)(song)機是輸(shu)(shu)(shu)送(song)(song)粉塵狀、小顆粒及小塊狀等埋(mai)(mai)刮(gua)板輸(shu)(shu)(shu)送(song)(song)機運輸(shu)(shu)(shu)設備(bei)，可以水(shui)平、傾(qing)斜(xie)輸(shu)(shu)(shu)送(song)(song)，輸(shu)(shu)(shu)送(song)(song)物(wu)料(liao)時，刮(gua)板鏈條(tiao)全(quan)埋(mai)(mai)在(zai)物(wu)料(liao)之中。埋(mai)(mai)刮(gua)板輸(shu)(shu)(shu)送(song)(song)機具有結構簡單，使(shi)用，造價低廉，輸(shu)(shu)(shu)送(song)(song)距離(li)長(chang)，并能(neng)輸(shu)(shu)(shu)送(song)(song)灼熱物(wu)料(liao)等優點。

埋刮板輸送機(ji)工作原(yuan)理：

埋刮板輸(shu)送(song)機(ji)在水平輸(shu)送(song)時(shi)，物(wu)(wu)(wu)料(liao)受到刮板鏈(lian)條在運動方向的(de)壓力及物(wu)(wu)(wu)料(liao)自身重量(liang)的(de)作(zuo)用(yong)，在物(wu)(wu)(wu)料(liao)間(jian)產生了(le)內摩(mo)擦(ca)力。這種(zhong)摩(mo)擦(ca)力了(le)料(liao)層(ceng)之間(jian)的(de)穩定(ding)狀態，并(bing)足以(yi)克服物(wu)(wu)(wu)料(liao)在機(ji)槽中(zhong)移動而(er)產生的(de)外摩(mo)擦(ca)力，使物(wu)(wu)(wu)料(liao)形成連(lian)續整(zheng)體的(de)料(liao)流而(er)被輸(shu)送(song)。

埋(mai)刮板(ban)輸送機技術特點(dian)：

1、用(yong)單(dan)條(tiao)礦(kuang)用(yong)圓環鏈拖動刮板(ban)，并選用(yong)凹齒型鏈輪進行驅動，具有負荷能力大，鏈條(tiao)壽命(ming)長(chang)和的特點。

2、鏈(lian)條能(neng)自動張緊(jin)，可鏈(lian)條在(zai)長時(shi)間內始終處于適度張緊(jin)狀(zhuang)態下運行，省去人工(gong)及時(shi)而頻繁的(de)緊(jin)張操作。

3、鏈(lian)(lian)(lian)條(tiao)和刮板(ban)回程(cheng)段由托輪支(zhi)承運行，不(bu)僅(jin)省力減磨，而且通(tong)過回鏈(lian)(lian)(lian)若干(gan)托輪間撓(nao)度(du)的自(zi)動變(bian)化，有助于鏈(lian)(lian)(lian)條(tiao)的自(zi)動漲緊(jin)及滑(hua)行。

4、如驅(qu)動機構(gou)背負在機頭上部與機殼自成一體(ti)，可使整體(ti)安裝不需用地(di)(di)腳螺栓即可就地(di)(di)自由放置而運行。

5、運行(xing)速度可采用YVP系(xi)列電(dian)機(ji)和變頻器組合控制，是   上調速方式。

6、進料方式采用兩(liang)側大(da)尺寸通過(guo)分流(liu)進入，使回程鏈條及(ji)刮(gua)板與進料隔離，并(bing)以不變(bian)的大(da)尺寸料層厚度向前輸送。使鏈條及(ji)刮(gua)板回帶物料的現象不再(zai)發生。

埋刮板(ban)輸送(song)機(ji)(ji)廣泛(fan)應用于建材、化工、冶(ye)金、煤炭(tan)、礦山(shan)、機(ji)(ji)械等部門。

埋(mai)刮(gua)板輸(shu)送機，結構簡單，重量輕(qing)，體(ti)積小，密閉(bi)性好，安裝維修比較方(fang)便(bian)；工藝布(bu)置較為靈(ling)活，既(ji)可(ke)水平輸(shu)送，又能傾斜或(huo)垂直輸(shu)送，還(huan)可(ke)多點加料和卸料；由于殼(ke)體(ti)是密閉(bi)的，因此(ci)在(zai)輸(shu)送物料過程中，對防治環(huan)境(jing)污染(ran)等(deng)方(fang)面具有突出的特(te)點，在(zai)糧油加工工藝中廣泛的應用。

刮(gua)板(ban)鏈(lian)條是埋刮(gua)板(ban)輸(shu)送(song)機(ji)(ji)中(zhong)主要的(de)(de)(de)工(gong)作(zuo)部件(jian)之一。埋刮(gua)板(ban)輸(shu)送(song)機(ji)(ji)的(de)(de)(de)各種故(gu)障都與刮(gua)板(ban)鏈(lian)條的(de)(de)(de)運(yun)行(xing)狀(zhuang)態有關(guan)，因此，物料(liao)的(de)(de)(de)輸(shu)送(song)效果與刮(gua)板(ban)鏈(lian)條結構型式(shi)的(de)(de)(de)選擇有較大的(de)(de)(de)關(guan)系。在糧油加工(gong)過程中(zhong)，常采用埋刮(gua)板(ban)輸(shu)送(song)機(ji)(ji)來連續輸(shu)送(song)顆粒散狀(zhuang)的(de)(de)(de)物料(liao)，其輸(shu)送(song)方式(shi)有水平，傾斜和垂直等型式(shi)。刮(gua)板(ban)鏈(lian)條是埋刮(gua)板(ban)輸(shu)送(song)機(ji)(ji)的(de)(de)(de)承載牽引構件(jian)。

由(you)于(yu)埋刮板輸送鏈條在(zai)被輸送的(de)物料(liao)中拖動，因此(ci)要防止被輸送物料(liao)將鏈條及(ji)應回轉的(de)零件擠死。叉型鏈的(de)特點是鉸(jiao)鏈處在(zai)鏈桿叉頭部(bu)(bu)位的(de)內部(bu)(bu)間隙大，又沒有滾(gun)子(zi)，故進入(ru)鉸(jiao)鏈的(de)物料(liao)容易排

除，是專門提(ti)供(gong)給埋刮板輸送機(ji)使用的輸送鏈(lian)條。

叉型鏈由只起到(dao)(dao)牽(qian)引作(zuo)用(yong)的(de)(de)(de)(de)基本(ben)鏈接與(yu)(yu)完成(cheng)刮(gua)(gua)送(song)作(zuo)業(ye)的(de)(de)(de)(de)刮(gua)(gua)板組(zu)成(cheng)，也稱之為刮(gua)(gua)板鏈條(tiao)。根據完成(cheng)刮(gua)(gua)送(song)作(zuo)業(ye)的(de)(de)(de)(de)刮(gua)(gua)板不同，其結構形(xing)(xing)式分為T形(xing)(xing)、V形(xing)(xing)、U形(xing)(xing)和(he)H形(xing)(xing)。埋(mai)(mai)刮(gua)(gua)板輸(shu)送(song)機(ji)用(yong)叉型鏈在埋(mai)(mai)刮(gua)(gua)板輸(shu)送(song)行(xing)業(ye)廣泛應(ying)用(yong)。埋(mai)(mai)刮(gua)(gua)板輸(shu)送(song)機(ji)在水平(ping)輸(shu)送(song)時，物(wu)(wu)料(liao)(liao)受(shou)到(dao)(dao)刮(gua)(gua)板鏈條(tiao)在運(yun)行(xing)方向上(shang)的(de)(de)(de)(de)推(tui)力(li)及(ji)自身的(de)(de)(de)(de)重力(li)的(de)(de)(de)(de)作(zuo)用(yong)，物(wu)(wu)料(liao)(liao)層之間產(chan)生(sheng)了(le)內(nei)(nei)摩(mo)(mo)(mo)擦(ca)力(li)。當(dang)這種內(nei)(nei)摩(mo)(mo)(mo)擦(ca)力(li)足以克服物(wu)(wu)料(liao)(liao)與(yu)(yu)槽(cao)壁間的(de)(de)(de)(de)外摩(mo)(mo)(mo)擦(ca)力(li)時，物(wu)(wu)料(liao)(liao)就隨同刮(gua)(gua)板鏈條(tiao)形(xing)(xing)成(cheng)連(lian)續整體(ti)的(de)(de)(de)(de)物(wu)(wu)料(liao)(liao)流(liu)而(er)被輸(shu)送(song)。在垂直輸(shu)送(song)時，物(wu)(wu)料(liao)(liao)受(shou)到(dao)(dao)刮(gua)(gua)板鏈條(tiao)在運(yun)行(xing)方向上(shang)的(de)(de)(de)(de)推(tui)力(li)。當(dang)由于(yu)橫向側壓力(li)而(er)產(chan)生(sheng)的(de)(de)(de)(de)內(nei)(nei)摩(mo)(mo)(mo)擦(ca)力(li)及(ji)下(xia)部不斷給料(liao)(liao)所產(chan)生(sheng)的(de)(de)(de)(de)對(dui)上(shang)部物(wu)(wu)料(liao)(liao)的(de)(de)(de)(de)推(tui)移力(li)，大(da)于(yu)物(wu)(wu)料(liao)(liao)與(yu)(yu)槽(cao)壁間的(de)(de)(de)(de)外摩(mo)(mo)(mo)擦(ca)力(li)和(he)物(wu)(wu)料(liao)(liao)的(de)(de)(de)(de)重力(li)時，物(wu)(wu)料(liao)(liao)就隨著刮(gua)(gua)板鏈條(tiao)形(xing)(xing)成(cheng)連(lian)續的(de)(de)(de)(de)物(wu)(wu)料(liao)(liao)流(liu)而(er)向上(shang)輸(shu)送(song)。

糧油加工工藝(yi)中，常見的埋(mai)刮(gua)(gua)板輸(shu)(shu)(shu)(shu)送(song)(song)(song)機多為(wei)MS型(xing)水(shui)平(ping)(ping)輸(shu)(shu)(shu)(shu)送(song)(song)(song)、MC型(xing)垂(chui)直輸(shu)(shu)(shu)(shu)送(song)(song)(song)、MZ型(xing)Z埋(mai)刮(gua)(gua)板輸(shu)(shu)(shu)(shu)送(song)(song)(song)3種(zhong)。水(shui)平(ping)(ping)輸(shu)(shu)(shu)(shu)送(song)(song)(song)機一(yi)般傾(qing)(qing)角(jiao)為(wei)0°～15°，如(ru)果輸(shu)(shu)(shu)(shu)送(song)(song)(song)是在物(wu)料充滿機槽的情況下進行，即(ji)使傾(qing)(qing)角(jiao)再大(da)些(xie)(xie)，仍能物(wu)料連(lian)續不斷地(di)輸(shu)(shu)(shu)(shu)送(song)(song)(song)。垂(chui)直輸(shu)(shu)(shu)(shu)送(song)(song)(song)機傾(qing)(qing)角(jiao)為(wei)30°～90°。Z埋(mai)刮(gua)(gua)板輸(shu)(shu)(shu)(shu)送(song)(song)(song)機輸(shu)(shu)(shu)(shu)送(song)(song)(song)高度一(yi)般在20m左右(you)，水(shui)平(ping)(ping)輸(shu)(shu)(shu)(shu)送(song)(song)(song)距離小(xiao)于(yu)30m。同時，也使用一(yi)些(xie)(xie)垂(chui)直環(huan)型(xing)刮(gua)(gua)板鏈條輸(shu)(shu)(shu)(shu)送(song)(song)(song)，如(ru)油料加工工藝(yi)中的環(huan)形浸出器(qi)和澄(cheng)油箱等，其目的主(zhu)要是在輸(shu)(shu)(shu)(shu)送(song)(song)(song)物(wu)料時完成(cheng)工藝(yi)過程(cheng)。
