One end of the scraper connecting rod 112 is fixedly connected to the scraper blade 111, and the other end is detachably connected to the scraper fixed shaft 12. An open coupling structure is adopted at the connection between the scraper fixed shaft 12 and the scraper connecting rod 112. The scraper connecting rod 112 is locked in the open coupling of the scraper fixed shaft 12 by multiple screws.

[0030] Preferably, in a scraping device for molten magnesium alloy of this embodiment, the scraper blade 111 is configured as a square blade, and the end of the scraper connecting rod 112 is vertically fixedly connected to a corner of the scraper blade 111, thereby increasing the effective scraping area of ​​the scraper blade 111.

[0031] The floating shaft 13 is disposed between the scraper fixed shaft 12 and the connecting flange 14 , and the floating shaft 13 is used for elastically floatingly connecting the scraper fixed shaft 12 and the connecting flange 14 .
