[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 2 , Figure 5 and Figure 6 , the utility model provides an embodiment: a shot blasting machine with a protective function, including a processing box 1, a box door 2 is hingedly connected to the front side of the processing box 1, a shot blaster 3 is arranged on the left side of the processing box 1, a motor 4 is fixedly connected to the top of the processing box 1, a turntable 5 is fixedly connected to the output end of the motor 4, a hook 6 is fixedly connected to the bottom of the turntable 5, an installation box 7 is fixedly connected to the rear side of the processing box 1, a fan 8 is arranged on the rear side of the installation box 7, a mounting handle 9 is slidably connected to the middle part of the installation box 7, a filter screen 10 is fixedly connected to the bottom of the installation handle 9, both sides of the outside of the installation box 7 are fixedly connected to a frame 14, a pull rod 15 is slidably connected to the inside of the frame 14, a baffle 16 is fixedly connected to one side of the outside of the pull rod 15, and a spring 17 is sleeved on the other side of the outside of the pull rod 15, and the installation box 7 is fixedly connected to the rear side of the processing box 1. A dust suction pipe 11 is fixedly connected to the right side of the packaging box 7, and a collecting port 12 is fixedly connected to one end of the dust suction pipe 11 away from the installation box 7. The top of the collecting port 12 is fixedly connected to the top wall of the processing box 1, and a filter screen 13 is fixedly connected inside the collecting port 12. A buffer assembly is arranged on the right side of the processing box 1, and a collecting box 27 is arranged below the processing box 1. Support columns 28 are fixedly connected to the bottom of the processing box 1 on all sides, a discharge port 29 is fixedly connected to the bottom of the processing box 1, and a handle 30 is fixedly connected to the front edge of the box door 2. The outside of the baffle 16 is slidably connected to the inside of the frame 14, one end of the spring 17 is fixedly connected to the middle of the baffle 16, and the other end of the spring 17 is fixedly connected to the inner wall of the frame 14. One end of the pull rod 15 passes through the installation box 7 and is inserted into the installation handle 9.

[0033] Specifically, when it is necessary to remove rust from the metal workpiece, the worker first easily pulls the handle 30, and the box door 2 opens smoothly. Next, the worker hangs the metal workpiece to be processed securely on the hook 6, and then starts the motor 4. The turntable 5 starts to rotate smoothly under the drive of the motor, and then drives the workpiece to rotate through the hook 6. At this time, the shot blaster 3 is started at the same time, which releases high-speed projectiles. These projectiles forcefully impact the surface of the metal workpiece and effectively remove rust and dirt. In order to ensure the efficiency and cleanliness during the rust removal process, it is very important to start the fan 8. The start of the fan 8 drives the efficient operation of the dust suction pipe 11. As the fan 8 runs, the dust suction pipe 11 quickly sucks in the mixture of metal waste slag and projectiles. In this process, the filter screen 13 plays a key role. It finely filters the mixture to ensure that the projectiles will not be accidentally sucked in, thereby ensuring the recycling of the projectiles and reducing waste. After the waste residue is filtered by the filter screen 13, it is smoothly sucked out through the collecting port 12 and transported to the inside of the installation box 7. At this time, the separated projectiles will fall into the collection box 27 through the discharge port 29. Here, the filter screen 10 plays a role again, and it further filters out the waste residue. However, long-term use may cause too much metal waste residue to accumulate on the filter screen 10, which may affect its filtering effect or even cause blockage. Therefore, it is particularly important to clean the filter screen 10 regularly. The worker only needs to simply pull the pull rod 15, and the baffle 16 will move synchronously and squeeze the spring 17. When the pull rod 15 is completely out of the installation handle 9, the disassembly of the filter screen 10 is easily completed. At this time, the worker can thoroughly clean the filter screen 10 to ensure that it restores good filtering performance. After cleaning, the filter screen 10 is placed in the installation box 7 again, and the pull rod 15 is reinserted into the installation handle 7. At this time, the spring 17 plays its reset function, restores the original state and pushes the baffle 16, so that the pull rod 15 is tightly inserted into the installation handle 9. In this way, the reinstallation of the filter screen 10 is successfully completed, and the equipment is restored to the best working state again, ready for the next metal rust removal task.

[0034] Reference Figure 1 , Figure 3 and Figure 4The buffer assembly includes a sleeve 18 and a mounting groove 21. The right end of the sleeve 18 is fixedly connected to the inner wall of the processing box 1, and the right side of the mounting groove 21 is fixedly connected to the inner wall of the processing box 1. The sleeve 18 is slidably connected with a telescopic rod 19, and a spring 20 is sleeved on the outside of the telescopic rod 19. A fixed rod 22 is fixedly connected to the inside of the mounting groove 21, and springs 3 23 are sleeved on both ends of the fixed rod 22. The two springs 3 23 are fixedly connected to sliders 24 on the opposite sides. The left sides of the two sliders 24 are rotatably connected to connecting rods 25, and the left sides of the two connecting rods 25 are fixedly connected to protective plates 26. The side end of the pull rod 15 is fixedly connected with an adjusting handle 31. The inside of the slider 24 is slidably connected to the outside of the fixed rod 22. One end of the spring 20 is fixedly connected to the left end of the sleeve 18, and the other end of the spring 20 is fixedly connected to the right side of the protective plate 26.

[0035] Specifically, when the shot blaster 2 ejects the projectiles at high speed, these projectiles continuously impact the housing of the device, which undoubtedly brings huge impact and stress to the housing of the device. Under the action of the protective plate 26, this impact and stress are effectively alleviated. First, when the protective plate 26 is impacted by the projectiles, it will quickly disperse and transfer these forces to the telescopic rods 19 around it. The structure of the telescopic rod 19 allows it to produce a certain degree of telescopic deformation when subjected to external force, thereby absorbing and dispersing these impact forces. At the same time, the spring 20 also plays a vital role. As the telescopic rod 19 is extended and retracted, the spring 20 is gradually compressed, and its own elastic deformation ability is used to further absorb and eliminate the impact force from the projectiles. When the middle part is impacted, the protective plate 26 will transfer the force to the connecting rod 25. The connecting rod 25 is tightly connected to the slider 24, so it drives the slider 24 to slide outside the fixed rod 22. This sliding motion not only disperses the impact force, but more importantly, the slider 24 compresses the spring three 23 during the sliding process. The spring three 23 also uses its excellent elastic deformation ability to effectively eliminate the impact force on the middle part, further protecting the device casing from damage.

[0036] Working principle: when it is necessary to remove rust from the metal workpiece, the worker first pulls the handle 30 to open the box door 2, hangs the workpiece on the hook 6, starts the motor 4 to drive the turntable 5 to rotate, and then rotates the workpiece through the hook 6, and starts the shot blaster 3 at the same time. The high-speed projectiles impact the surface of the metal workpiece for rust removal. In order to quickly separate the metal waste slag and the projectiles, the fan 8 is started at this time to drive the dust suction pipe 11 to work. Under the action of the filter 13, the projectiles can be prevented from being adsorbed, and then the waste slag is sucked out through the collection port 12, and the metal waste slag is transported to the inside of the installation box 7 and filtered out through the filter 10. At this time, the separated projectiles will fall into the collection box 27 through the discharge port 29. In order to prevent the metal waste slag from accumulating too much and clogging the filter, it is necessary to regularly clean the filter 10, and pull the fan 8 to clean the filter 10 regularly. The movable pull rod 15 drives the baffle 16 to move synchronously and squeeze the spring 17 until the pull rod 15 is completely out of the mounting handle 9, completing the disassembly of the filter 10. At this time, the filter 10 can be cleaned. After cleaning, the filter 10 is placed in the mounting box 7, and the pull rod 15 is inserted into the mounting handle 7. At this time, the spring 17 is reset to its original length to push the baffle 16 so that the pull rod 15 is tightly inserted into the mounting handle 9 to complete the installation. When the projectiles ejected from the shot blaster 2 at high speed impact the equipment casing for a long time, the protective plate 26 will transfer the force received on the surrounding areas to the telescopic rods 19 and springs 20 on the surrounding areas, and eliminate the force received on the surrounding areas by compressing the springs 20. At the same time, the protective plate 26 transfers the force received on the middle part to the connecting rod 25, and then drives the slider 24 to slide outside the fixed rod 22 and compresses the spring three 23 to eliminate the force received on the middle part.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
