The invention belongs to the field of shot blasting devices, and particularly discloses a shot blasting device. According to the main scheme, shot elevating plates upwards inclining towards a conveying device are hinged to material receiving plates, rust removal plates are fixed to the material receiving plates, and a cotton cloth layer is fixed to each rust removal plate. The rust removal platesare located on the sides, close to the conveying device, of the shot elevating plates. A pull plate is in sliding connection to each material receiving plate and is fixedly connected with ash flickingbelts for flicking away rust ash adhering to the cotton cloth layer. The ash flicking belts are made of elastic materials, the ends, away from the pull plates, of the ash flicking belts are fixedly connected to the rust removal plates, and the rust removal plates are provided with passing holes for the ash flicking belts to pass. A stay wire is fixed to the end, close to the conveying device, ofeach shot elevating plate and is wound to the position below the corresponding pull plate from the position above the corresponding shot elevating plate through a reversing pulley block and is fixed to the corresponding pull plate. The device wipes steel shots in the steel shot recycling process so that the dirt removal effect of a shot blasting machine can be improved.
