Shot-slag separation device for shot blasting machine

The utility model relates to the technical field of shot blasting machines, and discloses a shot-slag separation device for a shot blasting machine, the shot-slag separation device comprises a separation box body, the top of the separation box body is provided with a feeding pipe, and the bottom of the feeding pipe extends into the separation box body. According to the scheme, the first inclined pipe is arranged, steel shots directly pass through the first inclined pipe and the second inclined pipe to be discharged out of the transverse pipe due to the large inertia of the steel shots, meanwhile, when chippings pass through the first inclined pipe, first through holes are formed in the lower pipe wall of the first inclined pipe, a first filter screen is installed, and then the chippings are filtered out through the first filter screen; through cooperation of a second inclined pipe, a second through hole and a second filter screen, the chippings are further filtered out, an electric cylinder in a shaking mecha
