Abstract

The utility model provides a material clearing early warning device for a silicon material transfer tray, which comprises a transfer tray, a return guide rail and a hydraulic cylinder, a piston rod of the hydraulic cylinder pushes the transfer tray to move on the return guide rail, and a plurality of movable slots are arranged on the transfer tray; the device further comprises a support, a rotating shaft, a supporting body, a scraper strip, a first hook, a second hook, a tension spring, a photoelectric sensor and an alarm. The device has the advantages that the scraping plate strips can scrape silicon material fragments falling into the movable slots by utilizing the tension of the tension springs; and meanwhile, the photoelectric sensor can be triggered to detect and give an alarm through rotation of the scraper strip, so that derailing of the transfer tray and damage to equipment caused by derailing are avoided, and normal operation of production is guaranteed.
