However, most existing rust removal and grinding operations are carried out in open environments, generating large amounts of rust dust that flies everywhere. This not only poses serious health risks to operators, such as causing respiratory illnesses, but also pollutes the surrounding workplace environment, affects the normal operation of other equipment, and wastes metal resources. Furthermore, traditional simple dust collection devices often suffer from incomplete dust collection, poor adaptability to different sizes of I-beams, and inconvenient dust removal, making it difficult to meet the demands of efficient and environmentally friendly production.

Detailed Implementation
[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0018] Example 1, referring to Figure 1-3 A dust collection device for rust removal and grinding of I-beams includes a connecting plate 1. Both ends of the connecting plate 1 are rotatably connected to air collecting hoods 2. The upper ends of the two air collecting hoods 2 are connected to branch pipes 8. The two branch pipes 8 are connected to suction pipes 11 through tee connectors. One end of the suction pipes 11 is connected to a dust collection box 12. A collection component is installed inside the dust collection box 12. An air extraction component is installed at the bottom of one side of the dust collection box 12. A box door is provided on one side of the dust collection box 12. Electric push rods 16 are rotatably connected to opposite sides of the two air collecting hoods 2. The upper ends of the two electric push rods 16 are rotatably connected to a support plate 3. A U-shaped frame 4 is fixed to the upper end of the support plate 3. An mounting plate 5 is provided above the U-shaped frame 4. A strip hole 7 is provided on the mounting plate 5. A moving component is installed at the strip hole 7 and connected to the U-shaped frame 4.
[0019] The moving component includes a servo motor 6 and a bearing housing fixed at both ends of the upper surface of the mounting plate 5. The output end of the servo motor 6 is connected to a screw 10. One end of the screw 10 is rotatably connected to the bearing housing through a bearing. A moving block 9 is screwed onto the screw 10. The bottom of the moving block 9 is slidably engaged with the strip hole 7, and the bottom end of the moving block 9 is connected to the upper surface of the horizontal section of the U-shaped frame 4.
[0020] A support hole is provided on one vertical section of the U-shaped frame 4, and the suction pipe 11 passes through the support hole.
[0021] The collection assembly includes a partition 13 fixed in the middle of the inner wall of the dust collection box 12, a ventilation pipe 14 fixed in the middle of the partition 13, and a dust collection bag 15 fixed to the bottom of the outer wall of the ventilation pipe 14 by a clamp.
[0022] The exhaust assembly includes an exhaust fan 17 fixed to the bottom of one side of the dust collection box 12. The suction end of the exhaust fan 17 is connected to the interior of the dust collection box 12. Support wheels 18 are installed at the four corners of the lower end face of the dust collection box 12.
[0023] Working principle: The mounting plate 5 is bolted to the external support of the grinding workpiece. By controlling the extension and retraction of two electric push rods 16, the two air collection hoods 2 can be rotated, so that the two air collection hoods 2 face the two sides of the H-beam respectively. When grinding both sides of the H-beam simultaneously, the exhaust fan 17 is turned on, which creates a negative pressure inside the dust collection box 12, so that the grinding dust is absorbed by the air collection hoods 2. After entering the dust collection box 12, the dust is collected by the dust collection bag 15. The servo motor 6 drives the screw 10 to rotate, which in turn causes the moving block 9 to move the U-shaped frame 4, so that the two air collection hoods 2 move along the axial direction of the H-beam. This achieves simultaneous grinding, movement and dust collection, which improves the thoroughness of dust collection, eliminates the need for frequent adjustment of the H-beam position and improves grinding efficiency.
