[0049] Working principle:

[0050] When the shot blasting machine body 1 is used to blast the workpiece, the door 2 is opened, and the hook is used to lift the workpiece into the shot blasting machine body 1 through the movable channel 3, and then the door 2 is closed to perform the shot blasting work. This is the existing technology and will not be described in detail.

[0051] After the shot blasting of the workpiece is completed, in order to prevent the pellets from falling into the grooves of the workpiece and causing leakage of the pellets, an air jet assembly is used to blow the pellets on the workpiece into the shot blasting machine body 1; the first motor 7 is driven to rotate the first screw 10, so that the movable part 9 moves in the movable groove 8 toward the side close to the door 2; then the third motor 21 drives the slider 18 to move in the fixed block 17 toward the side away from the mounting shell 11; the second motor 13 rotates the worm 12, driving all the worm gears 15 to rotate, so that the rotating shaft 14 drives the jet head 6 to rotate toward the workpiece and swing up and down, and then the air pump 23 is used to blow air to the workpiece through the air pump diverter 4, the telescopic hose 5 and the jet head 6, and at the same time, the hook drives the workpiece to move back and forth and rotate in the shot blasting machine body 1, evenly blowing off the pellets on the workpiece. The hook drives the workpiece to move and rotate in the shot blasting machine body, which is an existing technology and is not described in detail.

[0052] Then the second motor 13 is used again to rotate the nozzle head 6 downward, and then the third motor 21 can be used to move the cover plate 19 to the side of the protective shell 16 to block the protective shell 16, thereby protecting the nozzle head 6; the first motor 7 drives the moving part 9 to move away from the door 2 to avoid interfering with the shot blasting process of the next batch of workpieces.

[0053] The inwardly inclined strips 22 prevent the pellets that fall on the bottom of the inner wall of the shot blasting machine body 1 from rolling out.
