Definitions

  • the field of the invention pertains to scarifier devices for removal of a portion of a flat surface such as on a floor, deck, bulkhead, roadway etc.
  • the invention relates to the cutter bit for a scarifier device.
  • a scarifier gouges or cuts and removes the surface revealing a lower surface. A new layer can then be placed on the lower surface. Similarly, a scarifier can be used to blend a higher portion of a concrete surface with the rest of the surface.
  • a scarifier uses a drum assembly with multiple cutter wheels having cutting bits.
  • the cutter wheels are mounted on a cutter shaft of the drum assembly.
  • the drum assembly moves and presents the cutting bits on the teeth of the cutter wheel to the surface to be scarified.
  • a problem with known scarifiers is that the cutter bits on the teeth of the cutter wheel are cutter bits that come to a point that does not cross or cover the full width of the cutter tooth. Another problem is that the cutter bits are not securely fastened to the cutter wheel and the cutter bits can become separated from the cutter wheel.
  • the invention is a cutter bit for a cutter wheel of a scarifier device.
  • the cutter wheel employs a cutter bit disposed across the full width of the tooth of the cutter wheel.
  • the cutter bit can be made from carbide or a material of similar hardness and durability.
  • the carbide cutter bit has a basic rectilinear shape as the cutter edge as viewed from the end of the cutter tooth.
  • Chamfers can abut the rectilinear shape of the cutter bit and extend to the body of the cutter bit.
  • the body of the cutter extends to a root.
  • the cutter bit interlocks to the cutter wheel keeping the cutter bit positioned to the cutter wheel.
  • the cutter bit can have an arcuate bulb on the root of the cutter bit.
  • the cutter wheel has a receiving slot for receiving the carbide cutter.
  • the receiving slot can have an arcuate part for matching with and for locking the cutter bit in place.
  • the receiving slot can also have a dovetail configuration near the root for receiving and locking a carbide cutter having a corresponding dovetail configuration. Other configurations for locking the cutter bit tot he cutter wheel can be advantageously employed.
  • the carbide cutter bit can be brazed into the receiving slot or pressed and locked into the receiving slot as designed.
  • the carbide cutter bit can also be positioned to the tooth of the cutter wheel as the cutter wheel is formed by being milled, stamped, formed by EDM (Electrical Discharge Machining), cast, broached or by other means, etc.
  • the cutter wheel can also employ an arcuate indent positioned vertically in a side of the pocket.
  • the arcuate indent can be positioned along two sides of the pocket.
  • Full width carbide cutter bits to be positioned to this cutter wheel can advantageously employ an arcuate portion on the side of the cutter bits. This allows the cutter bit to be securely retained in the pocket of the cutter wheel.

Abstract

L'invention concerne un outil de coupe ainsi qu'un procédé d'utilisation d'un trépan de coupe pour un scarificateur servant à scarifier ou à aplanir une couche de sol/plate-forme/plancher. Le trépan de coupe peut être en fabriqué avec du carbure ou un autre matériau qui présente des caractéristiques de dureté et de résistance similaires. L'outil de coupe possède un bord de coupe pleine largeur qui s'étend sur la dent de la molette coupante. L'outil de coupe pleine largeur du trépan de coupe peut s'étendre sur une largeur plus importante que celle du corps de coupe. Le trépan de coupe pleine largeur élimine les arêtes laissées par l'opération de scarification. Le trépan de coupe est bloqué dans une fente sur la dent de la molette coupante à l'aide d'un pied arqué, d'un pied en queue d'aronde, d'une partie arquée sur le trépan de coupe qui s'engage dans une indentation arquée dans la molette coupante, ou d'autres configurations encore. Le trépan de coupe peut être brasé sur place ou adapté sur place à la dent de coupe de la molette coupante.
