摘要

"Circular knife preferably applicable to seeding machines and fertilizadoras for cutting stubbles and the wind of the land to be cultivated.Includes a knife is of the type which presents a series of undulations, radial or tangential.Set in an annular band which extends between the perimeter of the knife and a circular central zone of the same; the profile of the corrugation has a development mainly in the form of a toothSierra of asymmetric geometry; the amplitude of each wave is defined by portions of the growth and decline in peak to peak linear; each of the corrugations form on the surface of the knife respectivelyThe flat faces in correlation with growth and decrease of amplitude of the ripples; according to the alternatives of manufacture.The corrugations extend radially with respect to the axis of rotation of the knife.Or tangentially with respect to the circular central zone of knife as a geometric axis longitudinal straight or curved.
