一、刮板鏈條的組成及類型。
由(you)於(yu)埋(mai)地(di)刮(gua)板(ban)輸(shu)送(song)鏈(lian)拖(tuo)動(dong)輸(shu)送(song)材(cai)料(liao)，因(yin)此(ci)有(you)必(bi)要(yao)防(fang)止(zhi)輸(shu)送(song)材(cai)料(liao)擠(ji)壓(ya)鏈(lian)條(tiao)和(he)旋(xuan)轉(zhuan)部(bu)件(jian)。叉(cha)鏈(lian)的(de)特(te)點(dian)是(shi)鏈(lian)杆(gan)叉(cha)頭(tou)內(nei)部(bu)間(jian)隙(xi)大(da)，沒(mei)有(you)滾(gun)輪(lun)，因(yin)此(ci)進(jin)入(ru)鉸(jiao)鏈(lian)的(de)材(cai)料(liao)很(hen)容(rong)易(yi)排(pai)除(chu)，是(shi)專(zhuan)門(men)為(wei)埋(mai)地(di)刮(gua)板(ban)輸(shu)送(song)機(ji)提(ti)供(gong)的(de)輸(shu)送(song)鏈(lian)。叉(cha)鏈(lian)由(you)隻(zhi)有(you)牽(qian)引(yin)作(zuo)用(yong)的(de)基(ji)本(ben)連(lian)接(jie)和(he)完(wan)成(cheng)刮(gua)刀(dao)操(cao)作(zuo)的(de)刮(gua)刀(dao)組(zu)成(cheng)，也(ye)稱(cheng)為(wei)刮(gua)刀(dao)鏈(lian)。根(gen)據(ju)刮(gua)板(ban)操(cao)作(zuo)的(de)不(bu)同(tong)，其(qi)結(jie)構(gou)分(fen)為(wei)T形、V形、U形和H形，如圖1所示。埋地刮板輸送機叉鏈廣泛應用於埋地刮板輸送行業。
