摘要:
In an earthmoving scraper, a pivotally adjustable router bit is provided on the leading edges of the bowl to fracture the soil ahead of both sides of the cutting edge of the scraper to protect the bowl sides from excessive wear. The bits are pivotally mounted on the side walls of the bowl and are shaped in such a way that the leading edge of each bit wears uniformly as the bit is advanced from one secured position on the bowl to the next.
