The invention discloses a hanging through type efficient shot
blasting machine which comprises a shot blasting chamber, a hanging device, an
auger device, an
elevator, a
cyclone dust collector and a filter
cartridge dust collector, the hanging device is arranged above the shot blasting chamber, the
auger device is arranged at the bottom of the shot blasting chamber, the
elevator is arranged on one side of the shot blasting chamber, and the
cyclone dust collector is arranged on the other side of the shot blasting chamber. The
cyclone dust collector is respectively connected with the shot blasting chamber and the return box through a dust removal pipeline, the filter
cartridge dust collector is connected with the cyclone dust collector through a dust removal pipeline, the
auger device comprises a blanking box, an auger and a
waste collection drawer, the blanking box is arranged at the bottom of the shot blasting chamber, the auger is transversely arranged in the blanking box, one end of the auger is in synchronous transmission connection with the
elevator, and the other end of the auger is in synchronous transmission connection with the
waste collection drawer. The waste collecting drawer is arranged at the bottom of the blanking box, and a
sieve plate is arranged between the blanking box and the waste collecting drawer. Through cooperation of the auger device and the elevator, used shots can be screened and recycled and conveyed back to the shot blasting device to be reused, raw materials are saved, and the shot blasting efficiency is improved.
