[0001] The utility model relates to the technical field of molds, in particular to a quick-install mechanism for a cyclone tube prefilter of an air filter. Background Art

[0002] With the continuous improvement of the degree of agricultural mechanization, the demand for agricultural harvesters and tractors has increased year by year. The annual output of air filter assemblies is more than hundreds of thousands of pieces. The cyclone tube pre-filter is an important component of the air filter assembly. It must be able to quickly and coarsely filter out more than 95% of the harvest dust, and must also meet the air filter assembly's intake resistance of ≤3.55MPa, be earthquake-resistant and durable, and the production cost must also be controlled.

[0003] When assembling the cyclone tubes on the air filter, the sealing needs to be ensured. However, there are a large number of cyclone tubes on the existing pre-filter, 31 sets. Therefore, the cyclone tubes and the partitions need to be assembled repeatedly up to 31 times, and they need to fit tightly. The process is cumbersome and slow, and the product quality is difficult to guarantee. Utility Model Content

[0015] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following briefly introduces the drawings required for describing the embodiments. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0017] Figure 2 This is a schematic diagram of the structure of the chassis of the utility model when it is pulled out from the slide rail.

[0018] Among them, the chassis 1, the partition 2, the pressure plate 3, the slide plate 4, the slide rail 5, the upper bracket 6, the lower bracket 7, the boost cylinder 8, the air filter swirl tube 9, the handle 10, the guide column 11, and the positioning block 12. DETAILED DESCRIPTION

[0019] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0020] The technical solution of the present utility model is further described below with reference to the accompanying drawings. Figure 1-2 The figure shows a quick-install mechanism for a cyclone tube pre-filter of an air filter, which includes a chassis 1, a partition 2, a pressure plate 3, a slide plate 4, a slide rail 5, an upper bracket 6, a lower bracket 7 and a booster cylinder 8. The upper bracket 6 is fixed to the four corners of the top of the lower bracket 7, the slide rail 5 is horizontally fixed to the top of the lower bracket 7 and extends from one end of the top of the lower bracket 7, the slide plate 4 is cooperated with the slide rail 5, and the chassis 1 is fixed to the slide plate 4.

[0021] The chassis 1 features a hole for installing one end of the air filter swirl tube 9. Guided guides are used to facilitate assembly. By using the chassis 1 in conjunction with the existing bulkhead 2, the two ends of the swirl tube are precisely positioned. The bulkhead 2 also features a hole for installing the other end of the air filter swirl tube 9. The multiple holes on the bulkhead align with the multiple swirl tubes. A booster cylinder 8 is vertically fixed to the top of the upper bracket 6. Its telescopic end passes through a through-hole in the top of the upper bracket 6 and is vertically connected to the pressure plate 3. When the bulkhead 2 is positioned between the upper bracket 6 and the lower bracket 7, the pressure plate 3 faces the bulkhead 2. The booster cylinder 8 operates vertically and is pneumatically powered. The pressure required by the air pump can be adjusted based on actual conditions. This controls the pressure plate to press 31 swirl tubes into the bulkhead holes at once, increasing production speed and ensuring product consistency. Pneumatic power conserves electricity, directly utilizing grid air pressure, making it safe, convenient, and energy-efficient.

[0022] When the pressure plate 3 repeatedly presses against the partition 2, it is prone to radial deviation, affecting the pressing effect and hindering the assembly of the swirl tube. To improve assembly quality, vertical guide posts 11 are provided at both ends of the pressure plate 3. This allows the booster cylinder 8 and the guide posts 11 to guide vertical movement between the upper bracket 6 and the lower bracket 7. This consistent and stable movement prevents the pressure plate 3, to which it is fixed, from being deflected. The pressure plate 3 can stably press the swirl tube into the hole of the partition 2, thus ensuring assembly quality.

[0023] Specifically, the chassis 1 and the partition 2 are each provided with a plurality of holes for the end of the cyclone tube 9 to be installed. The existing pre-filter cyclone tube has 31 groups, and 31 holes for the end of the cyclone tube 9 to be installed can be provided on the chassis 1 and the partition 2. The above-mentioned holes can be evenly arranged on the chassis 1 and the partition 2 in two circles.

[0024] In order to easily pull out the chassis 1, a handle 10 is provided on the slide 4, which is arranged in the direction of sliding of the slide 4. The operator can use both hands to quickly insert the swirl tube into the hole of the chassis 1 with high efficiency. After the assembly is completed, the chassis 1 is returned to its original position through the slide rail 5.

[0025] In order to provide a fixed limit for the slide rail 5 , ensure the consistency of the return, and ensure accurate positioning, a positioning block 12 is provided on the slide rail 5 .

[0026] The working principle of this utility model:

[0027] like Figure 2 , pull the chassis 1 out from between the upper bracket 6 and the lower bracket 7. The operator can operate with both hands at the same time, quickly insert one end of the swirl tube into the hole of the chassis 1, and then initially insert the swirl tube 9 into the corresponding hole of the partition 2, and then use the slide rail 5 to return the chassis 1, and use the positioning block 12 to ensure the return consistency, such as Figure 1 As shown, the partition 2 can always face the pressure plate 3. The booster cylinder 8 moves vertically, controlling the pressure plate 3 to press 31 swirl tubes 9 into the holes of the partition at one time, while ensuring the sealing and increasing the assembly speed, thereby reducing the scrap rate of parts and quality defects to ensure product consistency.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
