The invention discloses an aerated concrete dicing waste removing device. The aerated concrete dicing waste removing device comprises a fixing frame, a rotating shaft frame is fixedly connected to theleft side of the bottom of the fixing frame, an inner cavity of the rotating shaft frame is movably connected with a rotating shaft connecting plate through a rotating shaft, and fixing pipes are fixedly connected to the top and the bottom of the left side of the rotating shaft connecting plate. According to the aerated concrete dicing waste removing device, the fixing pipes, a moving rod, a connecting rod, a transmission rod, a frame, a first rotating rod, a rotating disc, a rotating block, a fixing rod, a first gear, a moving groove, a second rotating rod and a second gear are used in a cooperating mode, so that the problem that a traditional waste removing device is of a structure combining an overall frame with a fixed type scraping plate material removing frame, the position and theangle of a scraping plate are fixed in the process of producing by equipment, and then cut-in height and angle of the scraping plate cannot be adjusted in the follow-up process is solved, the waste removing device has the advantages that the height and the angle of the scraping plate can be adjusted, damage to a blank body is avoided in the cutting process, and the cost consumption is reduced.
