由于單鏈刮板輸送機鏈條在溜槽內不同的布置方式，常用的有邊雙鏈、中雙鏈及中單鏈。其特點分別是： a. 邊雙鏈。鏈條和連接環起向導作用，鏈條位于刮板兩端。其特點是過煤空間大，消耗能量小。其缺點是水平彎曲時鏈條受力不均勻，溜槽磨損較大。 b. 中雙鏈。刮板在溜槽內起向導作用，兩條鏈條在刮板中間，其間距不小于槽寬的20%，其特點是鏈條受力均勻，溜槽磨損小，水平彎曲性能好，機頭尺寸較小，單股鏈條斷時處理方便。缺點是過煤空間小，能量消耗大。 c. 中單鏈。刮板在溜槽內起導向作用，一條鏈條位于刮板中心。其特點是結構簡單，彎曲性能好，鏈條受力均勻，溜槽磨損小。其缺點是過煤空間小，機頭尺寸較大，能量消耗較大。 綜上，中單鏈刮板輸送機的(de)特(te)(te)點是結構簡單,事故少,受力(li)均(jun)勻,運行(xing)平穩,摩擦阻力(li)小,溜槽利用(yong)(yong)率高(gao)(gao)和彎(wan)曲性能好,在(zai)輸(shu)(shu)送(song)機(ji)(ji)(ji)上不易(yi)(yi)出現(xian)堵(du)塞(sai)。缺點是預張力(li)較大。中(zhong)單鏈可(ke)(ke)彎(wan)曲刮板(ban)輸(shu)(shu)送(song)機(ji)(ji)(ji)系列(lie)適(shi)用(yong)(yong)于厚度在(zai)0.8米以(yi)上，傾(qing)(qing)角(jiao)在(zai) ±15°之間(jian)的(de)緩(huan)傾(qing)(qing)斜工(gong)(gong)(gong)作面(mian)(mian)，也可(ke)(ke)用(yong)(yong)于順槽及煤(mei)巷掘(jue)進面(mian)(mian)。本機(ji)(ji)(ji)主(zhu)要適(shi)用(yong)(yong)于緩(huan)傾(qing)(qing)斜中(zhong)厚煤(mei)層長壁式經(jing)濟(ji)綜(zong)采(cai)(cai)或 普采(cai)(cai)的(de)回采(cai)(cai)工(gong)(gong)(gong)作面(mian)(mian)，在(zai)放頂(ding)煤(mei)回采(cai)(cai)工(gong)(gong)(gong)作面(mian)(mian)應用(yong)(yong)也越來越多，可(ke)(ke)與采(cai)(cai)煤(mei)機(ji)(ji)(ji)、液(ye)(ye)壓支架等(deng)設備配套，以(yi)實現(xian)回采(cai)(cai)工(gong)(gong)(gong)作面(mian)(mian)的(de)落(luo)煤(mei)、裝煤(mei)、運煤(mei)、支護和工(gong)(gong)(gong)作面(mian)(mian)的(de)連續作業等(deng)。又考(kao)慮(lv)到所(suo)設計(ji)的(de)刮板(ban)輸(shu)(shu)送(song)機(ji)(ji)(ji)的(de)運輸(shu)(shu)功率比較小和上述各(ge)種(zhong)鏈型(xing)的(de)特(te)(te)點，選用(yong)(yong)中(zhong)單鏈型(xing)刮板(ban)輸(shu)(shu)送(song)機(ji)(ji)(ji)。 目前，刮板(ban)輸(shu)(shu)送(song)機(ji)(ji)(ji)的(de)機(ji)(ji)(ji)頭(tou)、機(ji)(ji)(ji)尾(wei)部采(cai)(cai)用(yong)(yong)螺(luo)(luo)(luo)栓(shuan)連接(jie)，而(er)連接(jie)螺(luo)(luo)(luo)栓(shuan)強度不足，容(rong)易(yi)(yi)斷裂，可(ke)(ke)靠性不高(gao)(gao)，為(wei)此，本次設計(ji)機(ji)(ji)(ji)頭(tou)、機(ji)(ji)(ji)尾(wei)部采(cai)(cai)用(yong)(yong)焊(han)接(jie)板(ban)式，這(zhe)樣(yang)可(ke)(ke)以(yi)減少螺(luo)(luo)(luo)栓(shuan)連接(jie)不但(dan)可(ke)(ke)以(yi)提高(gao)(gao)可(ke)(ke)靠性，而(er)且可(ke)(ke)以(yi)減少孔和螺(luo)(luo)(luo)紋的(de)加工(gong)(gong)(gong)而(er)減少工(gong)(gong)(gong)序，降低成本。另(ling)外，考(kao)慮(lv)設計(ji)的(de)輸(shu)(shu)送(song)機(ji)(ji)(ji)運輸(shu)(shu)量較低，功率比較小，因此，即(ji)使(shi)重載啟動需要的(de)電動機(ji)(ji)(ji)轉矩也不會(hui)太大，電動機(ji)(ji)(ji)和減速器(qi)用(yong)(yong)彈(dan)性聯軸器(qi)連接(jie) 可(ke)(ke)以(yi)滿足要求，這(zhe)樣(yang)可(ke)(ke)以(yi)不使(shi)用(yong)(yong)液(ye)(ye)力(li)耦合器(qi)，
