Chain of earth-moving machine has cylindrical pins with bosses, outer and inner plates with end surfaces that are in pairs placed in pairs, in the plates two openings in each are provided, platforms with concave part to side of cutters fixed on those, first cutter in direction of motion of chain is installed on platform, in the point of long axis of chain, each next cutter - with step-by step deflection in cross direction and with alternation to opposite side. The bosses are rigidly connected to pins, each cutter with step-by step deflection in cross direction is installed with gradually larger turn of cuter about its axis to side of edge of platform nearer to which the cutter is fixed. In the place of maximal deflection two cutters are fixed. The front and the back end surfaces of plates are arranged with skews in the upper and the lower parts of end surfaces. |
