Abstract

The invention discloses a scraping plate protection mechanism of a vertical mill. The scraping plate protection mechanism of the vertical mill is used for protecting a scraping plate device of the vertical mill. A through hole through which the scraping plate device stretches into a mill shell is formed in the mill shell of the vertical mill; and a cover plate which covers the through hole is arranged at the outer end of the through hole. The scraping plate protection mechanism of the vertical mill comprises an elastic buffering device which is arranged on the cover plate, wherein an installation rod of the scraping plate device is connected with the elastic buffering device; and the installation rod is hinged on a supporting seat. The scraping plate protection mechanism provided by the invention has the advantages that: when too-large particles or large pig irons occur in the operation process of a scraping plate, the scraping plate can be impacted and forced to move to the inside of a milling cylinder along the inner wall of the milling cylinder, the installation rod of the scraping plate device pulls the elastic buffering device, the elastic buffering device is forced to be compressed under the action of a pulling force, and a clearance between the scraping plate and a milling surface of the milling cylinder is correspondingly enlarged, so that the scraping plate can be protected after crossing obstacles, and the elastic buffering device returns to an initial state after the scraping plate crosses the obstacles.
