Abstract: A debris cleaning mechanism and a cleaning device, comprising a driving mechanism, a transmission mechanism, and a debris scraping mechanism. The transmission mechanism comprises a gear box, and the gear box is connected to the driving mechanism by means of an input shaft and connected to the debris scraping mechanism by means of an output shaft; the debris scraping mechanism comprises a debris scraping body, and the output shaft is in transmission connection with the debris scraping body to drive the debris scraping body to move; the debris scraping body is provided with a first and/or a second debris scraping strip. The cleaning device comprises a debris barrel, a debris barrel cover, the debris cleaning mechanism, and a cover opening mechanism; when a rack of the transmission mechanism moves to a preset position along the axial direction of the debris barrel, the cover opening mechanism is pushed to move.
