用刮(gua)(gua)板(ban)(ban)(ban)鏈牽引，在槽(cao)內運送(song)(song)(song)散料的(de)輸(shu)(shu)送(song)(song)(song)機(ji)叫刮(gua)(gua)板(ban)(ban)(ban)輸(shu)(shu)送(song)(song)(song)機(ji)。刮(gua)(gua)板(ban)(ban)(ban)輸(shu)(shu)送(song)(song)(song)機(ji)刮(gua)(gua)板(ban)(ban)(ban)輸(shu)(shu)送(song)(song)(song)機(ji)的(de)相鄰中(zhong)部(bu)槽(cao)在水平、垂直面(mian)(mian)內可有限度(du)折曲(qu)的(de)叫可彎(wan)曲(qu)刮(gua)(gua)板(ban)(ban)(ban)輸(shu)(shu)送(song)(song)(song)機(ji)。其中(zhong)機(ji)身在工(gong)作面(mian)(mian)1和運輸(shu)(shu)巷(xiang)道交匯處呈(cheng)(cheng)90度(du)彎(wan)曲(qu)設(she)置的(de)工(gong)作面(mian)(mian)輸(shu)(shu)送(song)(song)(song)機(ji)叫“拐(guai)角(jiao)刮(gua)(gua)板(ban)(ban)(ban)輸(shu)(shu)送(song)(song)(song)機(ji)”。在當前(qian)采(cai)煤(mei)(mei)(mei)工(gong)作面(mian)(mian)內，刮(gua)(gua)板(ban)(ban)(ban)輸(shu)(shu)送(song)(song)(song)機(ji)的(de)作用不僅是運送(song)(song)(song)煤(mei)(mei)(mei)和物料，而且還(huan)是采(cai)煤(mei)(mei)(mei)機(ji)的(de)運行軌(gui)道，因此它成(cheng)為現代化采(cai)煤(mei)(mei)(mei)工(gong)藝(yi)中(zhong)的(de)主要(yao)設(she)備。刮(gua)(gua)板(ban)(ban)(ban)輸(shu)(shu)送(song)(song)(song)機(ji)能(neng)保(bao)持連續運轉，生產就能(neng)正常進(jin)行。否則，整個(ge)采(cai)煤(mei)(mei)(mei)工(gong)作面(mian)(mian)就會呈(cheng)(cheng)現停產狀態(tai)，使(shi)整個(ge)生產中(zhong)斷。

實際應用：

刮(gua)板(ban)(ban)輸(shu)(shu)送機可用于(yu)(yu)水平運輸(shu)(shu)，亦可用于(yu)(yu)傾(qing)(qing)斜運輸(shu)(shu)。沿傾(qing)(qing)斜向上運輸(shu)(shu)時，煤(mei)(mei)層(ceng)傾(qing)(qing)角(jiao)不得超(chao)(chao)過25°，向下運輸(shu)(shu)時，傾(qing)(qing)角(jiao)不得超(chao)(chao)過20°，當煤(mei)(mei)層(ceng)傾(qing)(qing)角(jiao)較大時，應安裝裝置(zhi)。可彎曲刮(gua)板(ban)(ban)輸(shu)(shu)送機允許在水平和垂直方向作2°～4°的彎曲。

工作原理：

刮(gua)(gua)板(ban)(ban)輸(shu)送機的工作(zuo)(zuo)原理是，將敞開(kai)的溜槽(cao)，作(zuo)(zuo)為煤炭(tan)、矸石或物料等的承受件，將刮(gua)(gua)板(ban)(ban)固定在鏈(lian)條上（組成(cheng)刮(gua)(gua)板(ban)(ban)鏈(lian)），作(zuo)(zuo)為牽(qian)引(yin)構件。當機頭(tou)傳動部啟動后，帶(dai)動機頭(tou)軸上的鏈(lian)輪旋(xuan)轉，使刮(gua)(gua)板(ban)(ban)鏈(lian)循(xun)環(huan)運行(xing)帶(dai)動物料沿著溜槽(cao)移(yi)動，直至到機頭(tou)部卸(xie)載。刮(gua)(gua)板(ban)(ban)鏈(lian)繞過鏈(lian)輪作(zuo)(zuo)無級閉(bi)合循(xun)環(huan)運行(xing)，完(wan)成(cheng)物料的輸(shu)送。

優點：

1、結構(gou)堅實。能經受(shou)住煤炭、矸石或(huo)其他(ta)物(wu)料的沖、撞(zhuang)、砸、壓等外力(li)作用(yong)。

2、能適應采煤工(gong)作(zuo)面底板(ban)不平、彎曲推移的需要(yao)，可以承受(shou)垂直或水平方向的彎曲。

3、機(ji)身矮，便于安裝。

4、能兼(jian)作(zuo)采煤機運行的(de)軌道。

5、可反向運(yun)行，便(bian)于處理底鏈(lian)事故(gu)。

6、能作液壓支架前段(duan)的(de)支點。

7、結構(gou)簡單，在輸送長度(du)上可任意點進料或卸料。

8、機殼密(mi)閉(bi)，可以防止(zhi)輸送物料時(shi)粉塵飛(fei)揚而污(wu)染(ran)環(huan)境。

9、當其尾部(bu)不設置(zhi)機殼(ke)，并將刮板插入料堆時，可自行取料輸送。
