Description

Technical Field

[0001] This utility model relates to the field of air filtration technology, specifically to an air filter device for a cutting machine. Background Technology

[0002] Rail cutting is an important part of railway maintenance, mainly including the replacement and cutting of old rails, as well as the trimming and processing of existing rails. Rail cutting projects require the development of specific construction plans based on actual conditions, determining the specific scope and process requirements of the cutting work. It also necessitates identifying potential problems during construction and developing corresponding solutions. Rail cutting machines can be classified by power source into internal combustion rail cutting machines and electric rail cutting machines. Internal combustion rail cutting machines primarily use gasoline engines and are suitable for use in remote areas without power supply. Electric rail cutting machines are more suitable for areas with convenient electrical circuits.

[0003] Air filters are an important component of rail cutting machines, primarily used to filter dust and impurities from the air, protecting the engine from damage. If the filter is not cleaned for a long time or is damaged, it will cause the engine to inhale a large amount of dust, resulting in reduced engine power and even engine damage. Existing air filters have filter cotton attached to their outer circumference to further improve filtration efficiency. However, the existing filter cotton is glued to the outer circumference of the air filter, which makes it extremely inconvenient to replace the filter cotton later, requiring the replacement of the entire filter element, which increases the operating cost. At the same time, if the filter cotton is not removed in time, it can also affect the engine's lifespan. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] To address the problem that in existing air filter technology, the filter cotton on the outer periphery is directly glued to the air filter, making replacement inconvenient and requiring the entire filter to be replaced, thus increasing operating costs, this invention provides an air filter device for a cutting machine. This device allows for convenient replacement of the filter cotton, ensuring the filtration efficiency of the air filter while reducing subsequent maintenance costs.

[0031] It should be noted that the air filter device for cutting machines described in this utility model is used in, but not limited to, the field of cutting machines. For ease of explanation, this utility model only uses the application of the air filter device for cutting machines in the field of cutting machines as an example. The principle of the air filter device for cutting machines applied to other types of equipment is essentially the same as that applied to the field of cutting machines, and will not be described in detail here.

[0032] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of an air filter device for a cutting machine according to an embodiment of the present invention. An air filter device for a cutting machine includes a housing 1, a filter screen 2, a removable filter cotton 3, and a limiting mechanism 4. The top and bottom inner walls of the housing 1 are each provided with a first limiting plate 11 and a second limiting plate 12, forming an installation track between the first limiting plate 11 and the second limiting plate 12. The filter screen 2 is disposed on the housing 1. The removable filter cotton 3 is disposed within the installation track and is used to cover the filter screen 2. The limiting mechanism 4 includes a fastener 41, a locking member 42, and a limiting member 43. The fastener 41 is connected to the housing 1 via the locking member 42 and the limiting member 43, and is used to limit the removable filter cotton 3, securing it to the outer periphery of the housing 1.

[0033] In this embodiment, the housing 1 is an integral structure. A filter screen 2 is installed in the middle of the housing 1. A first limiting plate 11 and a second limiting plate 12 are circumferentially arranged on the inner top wall and inner bottom wall of the housing 1. A gap is provided between the first limiting plate 11 and the second limiting plate 12 for placing the removable filter cotton 3. A limiting mechanism 4 is provided on the housing 1. Through the cooperation of fasteners 41, engaging parts 42 and limiting parts 43, the two ends of the removable filter cotton 3 can be limited, so that the removable filter cotton 3 is tightly attached to the housing 1. When it needs to be disassembled later, only the limiting mechanism 4 needs to be disassembled to replace the removable filter cotton 3. This effectively saves the usage cost and ensures the filtration efficiency of the air filter element.

[0034] In one embodiment, please refer to Figure 2 To facilitate the installation of the detachable filter cotton 3, the upper and lower ends of the housing 1 are respectively provided with a first groove 44 and a second groove 45. The inner walls of the first groove 44 and the second groove 45 are respectively provided with a plurality of first insertion holes 443 and second insertion holes 453. The fastener 41 includes a first connecting plate 411 and a second connecting plate 412. The first connecting plate 411 and the second connecting plate 412 are each provided with a positioning cylinder 413 that mates with the first insertion holes 443 and the second insertion holes 453. The sides of the first groove 44 and the second groove 45 are respectively provided with a first notch 441 and a second notch 451. The first notch 441 and the second notch 451 are respectively provided with a first post. The first column 442 and the second column 452 are respectively engaged with a first connecting plate 411 and a second connecting plate 412. The engaging member 42 includes an extension plate 421 provided on both sides of the first connecting plate 411 and the second connecting plate 412. The extension plate 421 is provided with a positioning block 422. The positioning block 422 is provided with a positioning notch 423. The positioning notch 423 is used to engage with the first column 442 or the second column 452. The first connecting plate 411 and the second connecting plate 412 are both provided with a limiting member 43 for positioning the detachable filter cotton 3. The limiting member 43 includes a plurality of limiting abutments 431.

[0035] In this embodiment, a first groove 44 and a second groove 45 are formed at the upper and lower ends of the front of the casing 1 to facilitate the setting of a first insertion hole 443 and a second insertion hole 453 within the first groove 44 and the second groove 45. A first notch 441 and a second notch 451 are respectively provided on both sides of the first groove 44 and the second groove 45 to facilitate the setting of a first pillar 442 and a second pillar 452 within the first notch 441 and the second notch 451. The first connecting plate 411 and the second connecting plate 412 can be inserted into the first groove 44 and the second groove 45. After assembly, the entire device is more integrated. Extension plates 421 are provided on both sides of the first connecting plate 411 and the second connecting plate 412. Positioning blocks 422 are provided on the extension plates 421. C-shaped positioning notches 423 are opened on the positioning blocks 422 to facilitate the entire positioning block 422 to be engaged with the first column 442 or the second column 452. This allows the first connecting plate 411 and the second connecting plate 412 to be tightly engaged in the first groove 44 and the second groove 45. Furthermore, the limiting abutment plate 431 can effectively secure both ends of the detachable filter cotton 3, making it less likely to fall off or loosen.

[0036] In one embodiment, please refer to Figure 1 - Figure 8 To improve the working efficiency of the limiting plate 431, the gap between the filter screens 2 is greater than the width of the limiting plate 431. An air inlet is provided at the lower end of the housing 1. The first connecting plate 411, the second connecting plate 412 and the positioning block 422 are all plastic deformable blocks. The outer walls of the first connecting plate 411 and the second connecting plate 412 are provided with protrusions.

[0037] In this embodiment, the gap between the filter screens 2 is greater than the width of a single limiting plate 431. This allows the limiting plate 431 to engage the detachable filter cotton 3 within the gap between the filter screens 2, further improving the stability of the detachable filter cotton 3 and preventing loosening. It also does not affect the normal use of the filter screens 2. Furthermore, by setting the first connecting plate 411, the second connecting plate 412, and the positioning block 422 as plastic deformable blocks, the deformability of the device can be enhanced. Additionally, protrusions are provided on the outer walls of the first connecting plate 411 and the second connecting plate 412, making it convenient for subsequent workers to pry the first connecting plate 411 and the second connecting plate 412 through the protrusions to disassemble them.

[0038] To better understand this utility model, the following is combined with... Figures 1 to 8The technical solution of this utility model is described in detail as follows: The operator presses the detachable filter cotton 3 into the gap between the first limiting plate 11 and the second limiting plate 12 at both ends, and surrounds the outer periphery of the housing 1, ensuring contact between its head and tail ends. The operator then presses the first connecting plate 411 and the second connecting plate 412 into the first groove 44 and the second groove 45, causing the positioning cylinder 413 to extend into the first insertion hole 443 and the second insertion hole 453 inside the first groove 44 and the second groove 45. When the positioning cylinder 413 extends into the first insertion hole 443 and the second insertion hole 453, the extension plates 421 on both sides of the first connecting plate 411 and the second connecting plate 412 drive the positioning notch 423 on the positioning block 422, engaging with the first column 442 and the second column 452 inside the first notch 441 and the second notch 451. This allows the first connecting plate 411 and the second connecting plate 412 to... The connecting plate 412 is assembled with the housing 1, covering the first groove 44 and the second groove 45. At the same time, it drives the limiting plate 431 to press the detachable filter cotton 3 tightly against the outer periphery of the filter screen 2. It should be noted that the gap between the filter screens 2 is larger than the width of a single limiting plate 431. This allows the limiting plate 431 to hold the detachable filter cotton 3 in place within the gap between the filter screens 2, thus ensuring the stability of the detachable filter cotton 3 and preventing it from loosening during actual use. When the detachable filter cotton 3 needs to be replaced later, simply pry open the protrusion on the back of the extension plate 421 to move the first connecting plate 411 and the second connecting plate 412 away from the first groove 44 and the second groove 45, and the detachable filter cotton 3 can be removed. This makes it convenient for staff to replace the filter, greatly improving the filtration efficiency of the filter element and reducing subsequent maintenance costs.

[0039] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
