Scraper blade of chip removal machine

The utility model relates to a scraping plate of a chip removal machine, which comprises a transverse plate and a vertical plate, the vertical plate is fixedly connected with the transverse plate, the vertical plate is perpendicular to the transverse plate, and a backflow port is arranged on the vertical plate. According to the scraper blade, the backflow port is additionally arranged on the basis of a traditional scraper blade, the problem that too much liquid is carried by a scraper blade chip removal machine can be effectively relieved, when the scraper blade scrapes chips generated after machining of a machine tool, due to the fact that cutting liquid carried out by the scraper blade can flow back into the chip removal machine again through the backflow port after the scraper blade reaches the lifting part, the chip removal efficiency is improved, and the chip removal efficiency is improved. And the chip liquid can be conveniently recycled after being filtered subsequently, and particularly, the cost of e
