With Rubbing Patents (Class 209/67)
  • Patent number: 4382471
    Abstract: A low damage beet cleaner and elevator for a beet harvester is described. Beets are lifted elevationally between a lugged, endless elevator draper and an endless, upwardly inclined belt having flexible, finger-like projections. The draper and the belt are driven through their respective circuits with the belt being driven at a speed faster than that of the draper. The speed differential between the belt and the draper causes the finger-like projections to flexibly engage with the beets producing a brushing effect on the beets to clean them while they are being elevated for loading.
