| description | The utility model relates to a silage header non-regrinding cutting serrated knife structure for surface strengthening treatment, and belongs to the technical field of silage harvesting machinery. According to the technical scheme, the cutting device comprises a cutting serrated knife (1) and a cutting cutterhead (2), the cutting serrated knife (1) is in a sector ring shape, and a tungsten carbide hardened coating (13) is sprayed on a cutting tooth blade (11) of the cutting serrated knife (1); and a plurality of sector-ring-shaped cutting serrated knives are fixed on the outer edge part of the cutting cutterhead (2) along the circumferential direction to integrally form a circular cutting serrated knife. The serrated cutter has the advantages that the defects of internal stress, cracks and the like generated by welding the cutting edge can be avoided, the problems that an existing cutter is poor in abrasion resistance and hard to keep long-lasting sharpness are effectively solved, the service life of the serr |
