The invention discloses a shot blasting and
sand blasting cleaning device. The shot blasting and
sand blasting cleaning device comprises a
machining chamber, a discharging device and a screening device, the discharging device comprises a limiting plate, a supporting frame, cleaning grooves, a partition plate, first springs, a movable plate, a communicating groove, a side door, movable rods, openings, ejector blocks, a first motor, first cams, a transmission rod, supports and a discharging hopper, and a limiting plate is fixedly connected into the
machining chamber; and the bottom end of the
machining chamber is fixedly connected with the supporting frame, the first motor is installed on the outer side wall of one end of the machining chamber, the side wall of the bottom end of the machining chamber is fixedly connected with the discharging hopper, and the side door is hinged to the outer side wall of one end of the machining chamber. According to the shot blasting and
sand blasting cleaning device, the first motor is started, the first motor drives the transmission rod to rotate between the supports, the transmission rod drives the first cams to rotate, the first cams are connected with the movable plate in a matched manner and push the movable plate to move upwards, the movable plate drives the movable rods to move upwards, the movable rods slide along the cleaning grooves, and the openings in the movable rods are communicated with the cleaning grooves, so that the shot blasting can fall conveniently.
