The utility model relates to the technical field of air preheaters, in particular to a novel ash removal mechanism of an air preheater, which comprises a pipeline, inlets are arranged on two sides of the top end of the pipeline, a motor is started to drive a transmission rod to rotate, the transmission rod drives a first bevel gear through a second bevel gear, and the first bevel gear simultaneously drives a third bevel gear. The bevel gears are connected in a meshed mode, the first bevel gear drives the two-way screw to rotate, the two-way screw rotates to drive the circular scraper to slide in the pipeline, dust on the inner wall of the pipeline is scraped down, and meanwhile the dust is pushed to the dust removal opening to be discharged, the circular scraper can comprehensively scrape the inner wall of the pipeline, and the dust removal efficiency is improved. And rotation of a third bevel gear can drive an arc-shaped scraping plate through a connecting rod, the arc-shaped scraping plate rotates to remove
