撥鏈器，也叫(jiao)分鏈器、撥叉，使用(yong)煤礦(kuang)井下用(yong)刮板輸送機和(he)順(shun)槽用(yong)刮板轉載機。

　　分(fen)為機頭撥鏈(lian)(lian)(lian)(lian)(lian)器(qi)(qi)和機尾撥鏈(lian)(lian)(lian)(lian)(lian)器(qi)(qi)，撥鏈(lian)(lian)(lian)(lian)(lian)器(qi)(qi)為焊接結構件，安裝(zhuang)撥鏈(lian)(lian)(lian)(lian)(lian)器(qi)(qi)時撥叉插(cha)入鏈(lian)(lian)(lian)(lian)(lian)輪齒(chi)的(de)溝槽(cao)內(nei)，使刮板(ban)鏈(lian)(lian)(lian)(lian)(lian)的(de)鏈(lian)(lian)(lian)(lian)(lian)條(tiao)與(yu)鏈(lian)(lian)(lian)(lian)(lian)輪能順利的(de)嚙合(he)和分(fen)離。撥鏈(lian)(lian)(lian)(lian)(lian)器(qi)(qi)的(de)作用是(shi)：防(fang)止鏈(lian)(lian)(lian)(lian)(lian)環卡(ka)在(zai)鏈(lian)(lian)(lian)(lian)(lian)輪溝槽(cao)內(nei)不能在(zai)正(zheng)常分(fen)離點脫開，并及時清除夾在(zai)鏈(lian)(lian)(lian)(lian)(lian)輪槽(cao)內(nei)的(de)雜(za)物，保證(zheng)鏈(lian)(lian)(lian)(lian)(lian)輪和刮板(ban)鏈(lian)(lian)(lian)(lian)(lian)的(de)正(zheng)常嚙合(he)。當上下(xia)兩受力磨損部(bu)位磨損后，可利用堆焊方式修阻(zu)鏈(lian)(lian)(lian)(lian)(lian)器(qi)(qi)用來在(zai)緊鏈(lian)(lian)(lian)(lian)(lian)過(guo)程(cheng)中(zhong)卡(ka)阻(zu)輸送(song)機上的(de)刮板(ban)鏈(lian)(lian)(lian)(lian)(lian)，使鏈(lian)(lian)(lian)(lian)(lian)條(tiao)。

　　撥(bo)鏈(lian)(lian)(lian)器用(yong)于(yu)機頭傳動部，其作用(yong)是在刮板輸送(song)機正常運轉過程(cheng)中起(qi)到將鏈(lian)(lian)(lian)條與鏈(lian)(lian)(lian)輪分離的(de)作用(yong)，撥(bo)鏈(lian)(lian)(lian)器因持續與鏈(lian)(lian)(lian)輪、鏈(lian)(lian)(lian)條接觸，也(ye)屬(shu)于(yu)易損零(ling)部件。

　　按使用機(ji)型(xing)可以分為：630刮(gua)板(ban)(ban)(ban)(ban)機(ji)、730刮(gua)板(ban)(ban)(ban)(ban)機(ji)、800刮(gua)板(ban)(ban)(ban)(ban)機(ji)、830刮(gua)板(ban)(ban)(ban)(ban)機(ji)、880刮(gua)板(ban)(ban)(ban)(ban)機(ji)等機(ji)型(xing)。

　　按主機(ji)(ji)(ji)(ji)廠可以(yi)分為：張家口煤(mei)機(ji)(ji)(ji)(ji)撥鏈(lian)(lian)器(qi)、西北奔(ben)牛撥鏈(lian)(lian)器(qi)、山(shan)東礦機(ji)(ji)(ji)(ji)撥鏈(lian)(lian)器(qi)、山(shan)西煤(mei)機(ji)(ji)(ji)(ji)廠撥鏈(lian)(lian)器(qi)、鄭煤(mei)機(ji)(ji)(ji)(ji)撥鏈(lian)(lian)器(qi)等。
