Scraper for cleaning the teeth of a rotary machine for primary earth moving

摘要

A scraper 100 for cleaning the teeth of a rotary machine 1, comprising a rotor 20 having radial tooth tools 40, is comprised of a hollow shaft 101 parallel to the rotor 20 and supporting scraping means 110 attached to it so as to bilaterally lap each radial tooth tool 40 and without interfering with the latter or with the rotor 20. Said scraper 100 is actuated by the rotary machine 1 via means 70 consisting of a chain type or gear cascade type kinematics. IMAGE
