一 概论截煤机和矿用康拜因的主要机构之一就是掏槽机构。掏槽机构有圆盘式的,截杆式的和截链式的三种。此种机构的功用就是在煤壁内做出一定形状的截缝来。因此,在这些圆盘,截杆和截链上都必需安装有能够楔入煤内的截齿,当这些圆盘,截杆或截链本身作旋转运动时,截链也跟着作相应的运动。若整个机器再有前进运动时,截齿就可以在煤壁内掏出所需要的各种截缝。由此可见,掏槽机构的工作情况在很大程度上决定着截煤机或矿用康拜因的工作情况。 An overview of coal cut and mine one of the main agencies of the corp. Is undercutting institutions. Undercut institutions have a disc-type, cut-off type and three kinds of chain-type. The function of such a mechanism is to make a certain shape of the seam in the coal seam. Therefore, in these discs, the cut-off and the cut-chain all must be equipped with picks capable of wedging in the coal, and when these discs, cut-off bars or cut-chains themselves make a rotational movement, the cut-chains also follow corresponding movements . If the whole machine moves forward again, the picks can take out all kinds of needles in the coal wall. Thus, undercutting the work of the organization to a large extent determines the work of coal cutter or mine Kang Bain.
