The top of the mounting frame 304 is movably connected to a mounting block 305, the outside of the mounting block 305 is fixedly installed with a second pressing plate 306, the outside of the mounting block 305 is provided with a folding plate 307, the outside of the mounting frame 304 is fixedly installed with a fixing plate 308, the top of the fixing plate 308 is movably connected to a sealing plate 309, the outside of the mounting frame 304 is fixedly installed with a sealing hair row 310, and the inside of the shot blasting chamber body 1 is provided with a diamond groove 311.

[0022] Specifically, Figure 2 As shown, the second pressing plate 306, the folding plate 307 and the sealing plate 309 are all made of polyurethane. The six second pressing plates 306 are folded and assembled to form a seamless joint in the form of mutual extrusion, and the hook 2 can be quickly closed when it leaves.

[0023] Specifically, Figure 2As shown, polyurethane material is a polymer compound. Polyurethane material exhibits good wear resistance and corrosion resistance in the internal environment of the shot blasting machine, which makes it an ideal choice for adapting to a variety of working environments. Polyurethane material also has good impact resistance and aging resistance, enabling it to maintain stable performance during long-term use. Polyurethane material also has high mechanical strength and cushioning performance, which can effectively reduce the vibration and noise of the equipment and improve the operating stability and service life of the equipment.

[0024] Specifically, Figure 1 As shown, most of the components of the device are installed by the cooperation of bolts and nuts, so as to achieve a graded design of the sealing device, which is easy to install and has a better sealing performance, and no unnecessary gaps will be generated when the hook 2 moves.

[0025] When implementing, follow these steps:

[0026] 1) First, the metal workpiece is driven by the hook 2 along the diamond groove 311 into the shot blasting chamber body 1;

[0027] 2) Then, during the ejection process, the metal projectile will be initially intercepted by the diamond-shaped groove 311, thereby ensuring that the projectile splashing is prevented to the greatest extent;

[0028] 3) The projectiles passing through the diamond groove 311 are intercepted for the second time by the sealing plate 309 and the sealing hair row 310. Some of the projectiles may pass through the secondary interception device and reach the second pressing plate 306 and the folding plate 307 to be intercepted for the third time;

[0029] 4) Finally, the rubber plate 303 is used to prevent the projectile from rushing out of the top of the device and reaching the outside of the device to achieve the purpose of four interceptions.

[0030] To sum up, the four-stage sealing cover on the top of the shot blasting chamber, when the hook 2 drives the metal workpiece into the device as a whole and starts to spray metal projectiles, the metal projectiles will be initially intercepted by the diamond groove 311, which can ensure that the projectiles are prevented from splashing to the greatest extent. When the projectiles pass through the diamond groove 311, they will also be intercepted for the second time by the sealing plate 309 and the sealing hair row 310. After some projectiles pass through the secondary interception device, they will encounter the second pressure plate 306 and the folding plate 307 and be intercepted for the third time due to the particularity of their materials. Finally, the rubber plate 303 will intercept the projectiles for the fourth time. Through these four interceptions, it is ensured that the projectiles rebound and fall back into the shot blasting chamber body 1, and it is ensured that no projectiles or dust overflow from the top, thereby achieving the purpose of multi-stage sealing of the top of the shot blasting chamber.
