[0026] An adsorption box 5 is embedded at one end of the top of the protective cover 2. A multi-stage dust filter box 6 is fixedly connected to one end of the adsorption box 5. An installation frame 7 is embedded inside the multi-stage dust filter box 6. A dust collection base plate 8 is installed at the bottom of the installation frame 7. A large-pore dust filter plate 9 is installed at the top center of the dust collection base plate 8. A small-pore dust filter plate 10 is installed at the top of the dust collection base plate 8 on one side of the large-pore dust filter plate 9. An adsorption fan 11 is fixedly installed at the middle end of the multi-stage dust filter box 6 away from the adsorption box 5. The edges of the large-pore dust filter plate 9 and the small-pore dust filter plate 10 are both connected to the installation frame 7. The inner walls are closely fitted together, and the tops of the large-pore dust filter plate 9 and the small-pore dust filter plate 10 are flush with the top of the multi-stage dust filter box 6. The axial flow fan 4 and the adsorption fan 11 work together to form an upward airflow around the shot blasting machine. The airflow guides the dust and impurities that seep out of the shot blasting machine and disperse them into the multi-stage dust filter box 6. The large-pore dust filter plate 9 and the small-pore dust filter plate 10 perform multi-stage filtration to intercept the dust and impurities, preventing the dust generated by shot blasting from being directly discharged into the air and causing the surrounding environment to become dirty and polluted. The filtration and interception effect is good.

[0027] A sealing top plate 12 is installed on the top of the multi-stage dust filter box 6. Mounting bolts 13 are symmetrically installed on both sides of the sealing top plate 12. Splicing protrusions 14 are connected to the top of both ends of the multi-stage dust filter box 6. Mounting holes 15 are symmetrically opened in the middle of the splicing protrusions 14. The sealing top plate 12 is tightly attached to the top of the large-hole dust filter plate 9 and the small-hole dust filter plate 10. The mounting bolts 13 and the mounting holes 15 are in corresponding positions. The sealing top plate 12 and the splicing protrusions 14 are fixedly connected by the mounting bolts 13. The sealing top plate 12 and the mounting bolts 13 cooperate with each other to press and stabilize the mounting frame 7, thereby locking and fixing the large-hole dust filter plate 9 and the small-hole dust filter plate 10 to prevent them from tilting and shaking inside the multi-stage dust filter box 6. At the same time, the dust accumulation bottom plate 8 plays a role in collecting the intercepted dust and impurities, which greatly facilitates subsequent disassembly and cleaning.

[0028] Protective doors 16 are symmetrically installed on both sides of the protective cover 2. Guide grooves 17 are symmetrically opened at both ends of the top of the positioning frame 1. A mounting bracket 18 is symmetrically fixedly installed at one end of the positioning frame 1. A hydraulic telescopic rod 19 is installed in the middle of the mounting bracket 18. A protective pad 20 is fixedly bonded to one inner wall of the protective cover 2. The two sides of the bottom end of the protective cover 2 are movably engaged with the inside of the guide groove 17. The ends of the two hydraulic telescopic rods 19 are connected to the back of the protective cover 2. By using the protective cover 2 and the protective doors 16 in cooperation, the protective cover 2 plays a role in wrapping and protecting the shot blasting machine during the shot blasting process, preventing the shot from splashing outward and hitting the workers or damaging the surrounding equipment, thus improving the safety of the process. At the same time, by using the hydraulic telescopic rods 19 and the guide grooves 17 in cooperation, the position of the protective cover 2 can be adjusted to achieve both coverage protection and exposure treatment of the shot blasting machine. The adjustment and operation are simple.

[0029] The working principle and usage process of this utility model are as follows: First, open the two protective doors 16 outwards, extend the hydraulic telescopic rod 19 forward, and push the protective cover 2 forward along the guide groove 17 so that the protective cover 2 covers the shot blasting machine. The protective pad 20 can buffer the contact between the protective cover 2 and the shot blasting machine. Close the two protective doors 16. When the shot blasting machine is running, the protective cover 2 and the protective door 16 wrap and protect the shot blasting machine to prevent the shot inside the shot blasting machine from splashing outwards. The protective cover 2 and the protective door 16 intercept the splashed shot, which improves the safety of processing.

[0030] When high-speed shot blasting is used to treat the surface of a workpiece, some impurities and dust will drift outward along the gaps in the shot blasting machine and enter the interior of the protective cover 2. The axial flow fan 4 and the adsorption fan 11 are turned on. The axial flow fan 4 generates airflow, which is injected into the interior of the protective cover 2 through the gas distribution box 3. The adsorption fan 11 adsorbs the airflow, causing the airflow inside the protective cover 2 to flow from bottom to top and enter the adsorption box 5 and the multi-stage dust filter box 6. The drifting impurities and dust will flow with the airflow. The airflow passes through the large-pore dust filter plate 9 and the small-pore dust filter plate 10 in sequence. The large-pore dust filter plate 9 intercepts large particles of impurities in the airflow, and the small-pore dust filter plate 10 intercepts small particles of dust in the airflow, preventing impurities from being directly discharged into the outside air. The impurity particles will fall and accumulate on the surface of the dust accumulation base plate 8.

[0031] After shot blasting is completed, open the protective door 16, and use the hydraulic telescopic rod 19 to pull the protective cover 2 to re-expose the shot blasting machine, making it convenient to remove the processed workpiece and operate the shot blasting machine.

[0032] Regularly clean the inside of the multi-stage dust filter box 6. Tighten the mounting bolts 13 to loosen the fixing of the sealing top plate 12, lift the mounting frame 7 upwards and remove it. Clean the large-hole dust filter plate 9, the small-hole dust filter plate 10 and the dust accumulation bottom plate 8. After cleaning, reinsert it into the inside of the multi-stage dust filter box 6. Use the mounting bolts 13 to align with the mounting holes 15 and fix the sealing top plate 12 to the top of the multi-stage dust filter box 6.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
