PLOUGHSHARE OF SOIL-CULTIVATING IMPLEMENT

摘要

A ploughshare of a soil-cultivating implement comprises a base with a blade and cover plates. The cover plates are made as truncated cones and fixed by large planes thereof on the upper surface of the ploughshare base with spacing equal to the one-and-a-half of the width of the base. The diameter of the large planes of the cones of the cover plates is not larger than the width of the ploughshare base, the diameter of lesser planes of the cones of the cover plates is not less than the width of the ploughshare blade. The height of the cones of the cover plates is equal to the double thickness of the ploughshare base.
