Blade segment and blade assembly for a surface working vehicle

摘要

Abstract A segmented blade comprised of overlapping blade segments is disclosed herein. Each blade segment overlaps with adjacent segments thereby providing for an 5 overlapping joint between segments. The overlapping joint reduces erosion and/or washout of the underlying moldboard. Further, in one embodiment, the overlapping joint may include a connector hole such as a bolt hole through which a bolt detachably connects the overlapped sections of adjacent blade segments with the moldboard. Such a connection increases the strength of the connection as well as the strength of D the moldboard in the region of the connection. This allows for smaller blade segments to be used and allows for segments which are of a suitable size to be manhandled by a single operator without jeopardizing the strength of the moldboard and/or the longevity of the moldboard.
