[0033] The second embodiment is mainly different from the first embodiment in that: a dust-proof device for loading and unloading cargo at a port, the dust-proof component 3 includes a positioning plate 31 fixedly connected to the bottom of the top cover plate 1, the bottom of the positioning plate 31 is fixedly connected to an elastic jacket 32, one side of the inner wall of the positioning plate 31 is fixedly connected to a mounting frame 33, the inner wall of the mounting frame 33 is movably connected to a connecting folding plate 34, one side of the connecting folding plate 34 is fixedly connected to an inner pad 35, one side of the inner pad 35 is fixedly connected to a side edge of the elastic jacket 32 ​​by Velcro, the mounting component 4 includes a connecting plate 41 fixedly connected to the inner wall of the circular groove 2, a positioning groove 42 is provided on the surface of the connecting plate 41, a square frame 43 is fixedly connected to one side of the connecting plate 41, the square frames 43 are all the same size, a stepped groove 44 is provided on the surface of the square frame 43, and the inner wall of the stepped groove 44 is movably connected It is dynamically connected with an embedded plate 45, and the bottom of the embedded plate 45 is fixedly connected with a plug-in threaded rod 46, and the surface of the plug-in threaded rod 46 is threadedly connected with a positioning nut 47. One side of the embedded plate 45 is fixedly connected with a rectangular frame 48. The rectangular frames 48 corresponding to different types of equipment are different, so that they can be replaced during actual production. Both sides of the rectangular frame 48 are fixedly connected with surrounding plates 49, and one side of the surrounding plate 49 is fixedly connected with a fixed block 410. The inner wall of the fixed block 410 is penetrated by a manual screw 411, and one end of the manual screw 411 is fixedly connected with a contact plate 412.

[0034] The inner pad 35 is a flexible inner pad that can expand and contract simultaneously with the inner pad 35 , and anti-slip bumps are provided on the surface of the contact plate 412 .

[0035] After the grab equipment is opened, the material will fall freely under the action of gravity. However, as a large amount of material falls down, air will enter the protective cover bag, forming a strong positive pressure flow in the protective cover bag. This part of the air pressure is exactly opposite to the airflow of loading and unloading materials, thereby forming a force that pushes the material upward. This force has a great influence on the material particles, causing these material particles to suspend and adhere to the inner wall of the protective cover bag for a long time, and continue to diffuse outside the protective cover bag. When they are directly blocked by the protective cover bag.

[0036] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

Then the device is put on the surface of the grab bucket, and the grab bucket surface fits tightly with the rectangular frame 48 and the surrounding plate 49. The manual screw 411 is rotated to drive the contact plate 412 to insert into the top connecting structure of the grab bucket, and the device is stably fixed. When the grab bucket is working, the inner pad 35 can fit on the top of the bulk material at the same time as the elastic jacket 32 ​​to prevent the cargo from being affected by the airflow and causing dust to fly. When maintaining the inner pad 35, directly pull up the plug-in folding plate 34 on the inner wall of the mounting frame 33 to separate the plug-in folding plate 34 from the mounting frame 33. The inner pad 35 is connected to the plug-in folding plate 34 by Velcro, which can be directly torn off for cleaning and replacement. When the device is finished working, the device is restored.
