[0028] To make the objectives, advantages and features of the present utility model clearer, the following further details a round-top and square-bottom filter cloth dust cover proposed by the present utility model in conjunction with the attached drawings and specific embodiments. According to the following specific implementation modes, the advantages and features of the present utility model will be clearer.

[0029] See Figure 1 , a round-top and square-bottom filter cloth dust cover in this embodiment mainly includes a circular ring 1, a rectangular ring 2 and a dust cover body 3.

[0030] Among them, the circular ring 1 is fixedly installed on the upper and lower sides of the dust-proof working mechanism 01 to be protected. The rectangular ring 2 is sleeved on the lower side of the circumference of the dust-proof working mechanism 01 to be protected, and the length of the rectangular ring 2 is greater than the diameter of the circular ring 1, and the width is less than the diameter of the circular ring 1. This can not only reduce the size of the overall dust cover, but also place the rectangular ring 2 above the circular ring 1 during maintenance, facilitating maintenance.

[0031] The dust cover body 3 covers the circumference of the dust-proof working mechanism 01 to be protected. The dust cover body 3 can be made of a relatively thin soft material, such as filter cloth, etc.

[0032] The upper end of the dust cover body 3 is hermetically fixed on the circular ring 1; specifically, a first elastic sealing ring 5 is sleeved on the circular ring 1, a hose clamp 4 is sleeved on the first elastic sealing ring 5, and a hose clamp sheath 6 is sleeved on the hose clamp 4. After the upper end of the dust cover body 3 is bent inward and downward, it is clamped between the first elastic sealing ring 5 and the hose clamp sheath 6, and is hermetically fixed on the circular ring 1 through the hose clamp 4. The first elastic sealing ring 5 is specifically made of a soft foam rubber strip in this embodiment, and the soft foam rubber strip is adhesively fixed on the outer ring of the circular ring 1. [[ID=??]] [[ID=??]]

[0033] The lower end of the dust cover body 3 is hermetically fixed on the rectangular ring 2. Specifically, the lower end of the dust cover body 3 fits and wraps around the outer ring, lower side and inner side of the rectangular ring 2. In addition, a second elastic sealing ring 7 is provided. The upper side of the second elastic sealing ring 7 is provided with an opening, and the inner side thereof is provided with anti-slip protrusions; the lower side of the second elastic sealing ring 7 is provided with a closed cavity with a circular cross-section, and the closed cavity is not communicated with the opening. The rectangular ring 2 is sleeved on the lower side of the circumference of the dust-proof working mechanism 01 to be protected through the closed cavity. The second elastic sealing ring 7 is sleeved on the rectangular ring 2 from bottom to top through the opening, and the weight of the rectangular ring 2 is used to fix the dust cover body 3 located on the outer ring, lower side and inner side of the rectangular ring 2 on the rectangular ring 2.

[0034] During use, the upper and lower ends of the dust cover body 3 are respectively fixed on the circular ring 1 and the rectangular ring 2, so that dust prevention can be achieved through the dust cover body 3; when it is necessary to repair the working mechanism 01, the rectangular ring 2 can be manually tilted at a certain angle, passed through the circular ring 1 from the outside, first place one long side of the rectangular ring 2 on the circular ring, and move it inward along the short side direction of the rectangular ring 2, then pass the other long side of the rectangular ring 2 through the circular ring and move it inward along the short side direction of the rectangular ring 2 and place it on the circular ring 1, then the working mechanism 01 can be exposed for repair; after the repair is completed, reset the rectangular ring 2.
