SELF-SUPPORTING KNIFE BLADE FOR MINE SWEEPER

摘要

The invention relates to a self-propelled blade with knives, for mine sweepers, adapted to work in desert sandy soils. The blade has in its lower part a plate under which are mounted some knives; the plate has a relatively large surface, because of an optimum positive lift angle created between the blade plane and the advancing direction; the knives have a lower side of a determined surface which together with the advancing direction creates an optimum positive lift angle, which ensures the blade lift.
