The invention discloses a scraped glass smashing device which comprises a vibration breaking device which comprises a vibration hammer, a vibration generator and a breaking platform. The vibration generator is used for driving the vibration hammer to vibrate up and down, and the breaking platform is arranged below the vibration hammer and used for bearing scraped glass. Glass substrates are smashed through up and down vibration of the vibration hammer of the vibration breaking device, and scraped glass substrates with larger size are quickly decomposed into small broken glass particles for convenience for transport and subsequent treatment; in addition, the vibration hammer of the vibration smashing device during vibration enables the glass substrates to generate multiple cracks to be smashed into multiple blocks, efficiency is greatly improved when compared with the cutting mode, the vibration hammer can smash the glass substrates into smaller fragments, but more time is needed to obtain fragments identical in size by means of cutting; and moreover, the scraped glass smashing device is free of manual direct operation, only the vibration is needed to operate for vibration, so that safety is also greatly improved.
