[0023] (2) In the shot blasting cleaning machine with a top multi-layer sealing device described in the present invention, during the process of cleaning rust, the auger frame drives the spherical body downward through the semicircular block, the first torsion spring, the short bolt, the rotating block and the round rod, so that the spherical body drives the movable plate downward through the clamping block, the center rod, the fixed frame, the L-shaped frame plate and the support rod. When the clamping block is supported by the elastic force and detached from the spherical body, the first spring uses the elastic force to drive the movable plate to move upward through the telescopic rod, collides with the inner plate to generate vibration, thereby being able to shake off the rust adsorbed on the top cover and the inner wall of the expansion shell, thereby preventing the rust from accumulating.

[0024] (3) In the shot blasting cleaning machine with a top multi-layer sealing device described in the present invention, when the auger frame drives the steel shot, rust and other impurities to be transported, the scraper brush moves back and forth to clean the bottom of the filter shell, thereby clearing the rust and smaller impurities blocked in the filter holes in the filter shell, thereby improving the screening effect of the filter shell on rust and impurities.

[0025] (4) The shot blasting cleaning machine with a top multi-layer sealing device described in the present invention drives the roller brush to rotate by a driving motor, thereby rolling and cleaning the steel shots, rust ash and impurities generated on the top of the workpiece passing by. The dust suction motor absorbs the cleaned steel shots, rust ash and impurities into the filter shell through the air pipe and the suction shell, thereby facilitating the cleaning of the workpiece.

When the workpiece moves to the corresponding position of the shot blasting machine body 1, the shot blasting machine body 1 transports the steel shots to the inner side of the multi-layer top shell 2. The steel shot is shot blasted on the workpiece through the top opening 6. At the same time, the top opening 6 ejects part of the steel shot from the bottom opening 8 through the connecting pipe 7, and cooperates with the top opening 6 to perform shot blasting cleaning on the workpiece. By starting the driving motor 15 and the dust suction motor 62 to operate, the dust suction motor 62 generates suction force on the air in the top cover 9 and the expansion shell 10. When rust ash is generated by shot blasting, the suction force can absorb the rust ash to the inside of the expansion shell 10. The driving motor 15 drives the auger frame 16 to rotate, so that the auger frame 16 drives the steel shot, rust ash and other impurities to be transported. During the transportation process, the rust ash and smaller impurities are The particles are screened out through the filter housing 14. In the process of cleaning the rust and ash, the auger frame 16 drives the spherical body 22 to move downward through the semicircular block 17, the first torsion spring 18, the short bolt 19, the rotating block 20 and the round rod 21, so that the spherical body 22 drives the movable plate 26 to move downward through the clamping block 32, the center rod 31, the fixing frame 30, the L-shaped frame plate 29 and the supporting rod 28. When the clamping block 32 is supported by the elastic force and separated from the spherical body 22, the first spring 24 drives the movable plate 26 to move upward through the telescopic rod 25 by the elastic force, collides with the inner plate 34 to generate vibration, and the movable plate 26 moves upward. The rust and ash adsorbed on the inner wall of the top cover 9 and the expansion shell 10 can be shaken off. When the auger frame 16 drives the steel shot, rust and other impurities to be transported, the scraper 51 moves back and forth to clean the bottom of the filter shell 14, so that the rust and smaller impurities blocked in the filter hole of the filter shell 14 can be cleared. The steel shot and larger impurities are moved to the conveying member 63 through the auger frame 16, and are transported to the shot blasting machine body 1 through the conveying member 63. After being filtered by the shot blasting machine body 1, the steel shot is reused for shot blasting, and the filtered impurities are discharged through the output pipe 65.

[0051] During the shot blasting process of the workpiece, the roller brush 57 is rotated by driving the motor 15 to roll and clean the steel shots, rust ash and impurities generated on the top of the workpiece. The dust suction motor 62 absorbs the cleaned steel shots, rust ash and impurities into the filter shell 14 through the air pipe 58 and the suction shell 59, and cleans the steel shots, rust ash and impurities on the top of the workpiece.
