[0002] Current cotton harvesting technology typically uses machines, and the harvest process inevitably introduces a certain percentage of sterile seeds, which often carry neps and reduce the final cotton quality. Furthermore, the operation of the cotton pickers also increases the amount of immature or undersized short fibers, directly impacting cotton quality and making subsequent processing more difficult.

[0003] Another key issue is that existing cotton cleaning machinery is primarily designed to remove large impurities, such as stems and leaves. However, it is unable to handle smaller impurities, such as cotton leaves and fine impurities. This limitation results in inefficient removal of fine impurities from cotton fibers, severely impacting the purity of the cotton and the efficiency of the textile process. Utility Model Content

[0039] The terms such as "upper", "lower", "left", "right", "middle", etc. cited in this application are usually used to indicate the general relative position relationship for the convenience of intuitive understanding by referring to the drawings, and are not absolute limitations on the position relationship in the actual product.

[0040] Example 1

[0041] A soft loosening airflow type cotton cleaning machine, refer to Figure 1 The present invention comprises a dust cage 1 and a body 2, wherein the dust cage 1 is disposed on the top of the body 2. A cotton inlet channel 3 is disposed on the top of the dust cage 1, and the lower end of the cotton inlet channel 3 extends into the interior of the dust cage 1 for introducing cotton into the dust cage 1. In some embodiments, the lower end of the cotton inlet channel 3 is bent to one side so that the opening faces the side rather than the bottom. Furthermore, the cotton inlet channel 3 is rotatable. By rotating the cotton inlet channel 3, the cotton is dispersed around the dust cage 1, which can effectively prevent the accumulation of cotton in the dust cage 1.

[0042] The dust cage 1 also includes a cotton feed hopper 4 located below the cotton feed channel 3, which receives cotton from the channel. The dust cage 1 is provided with mesh holes, through which impurities adhering to the cotton are removed after it enters the dust cage 1. The bottom sidewalls of the dust cage 1 also include multiple first dust collection outlets 5.

[0043] Reference Figure 2-Figure 4 Inside the machine body 2, from top to bottom, there are provided a cotton inlet channel 6, a beater 7, a cotton outlet channel 8, a first dust removal knife group 9, a second dust removal knife group 10 and a debris removal channel 11. The specific configuration is as follows:

[0044] The upper end of the cotton inlet channel 6 is communicated with the lower end of the cotton inlet funnel 4, and the lower end is inclined toward the front side of the machine body 2 to guide the cotton.

[0045] The beater 7 is cylindrical, with multiple teeth evenly arranged around its periphery, for loosening the cotton. The beater 7 is rotatably connected to the machine body 2, with its axis of rotation horizontally arranged along the left-right direction of the machine body 2. During operation, the beater 7 rotates counterclockwise, with its teeth sequentially passing through the front, lower, rear, and upper ends of the beater 7. The lower end of the cotton inlet channel 6 abuts against the frontmost teeth of the beater 7, allowing the cotton, after exiting the lower end of the cotton inlet channel 6, to be directly drawn into the teeth of the beater 7.

[0046] The cotton outlet channel 8 is positioned at the rear of the machine body 2, with one end abutting the rearmost protruding teeth of the beater 7 and the other end extending outside the machine body 2. It should be noted that in this embodiment, two cotton outlet channels 8 are provided, one extending upward and one extending downward. This allows the cotton to be discharged from the machine body 2 through the upper cotton outlet channel 8 due to the rotational inertia of the beater 7. However, some cotton may fall into the lower cotton outlet channel 8 due to insufficient inertia and be discharged from the machine body 2. The provision of two cotton outlet channels 8 reduces the probability of cotton falling and backflow, thereby improving cotton cleaning efficiency.

[0047] Furthermore, since a large portion of the airflow exits with the cotton when the beater 7 is in operation, a portion of the airflow circulates with the backflow of the beater 7 and cannot be discharged. Therefore, a dust removal screen plate 12 is connected between the cotton inlet channel 6 and the cotton outlet channel 8, and is located above the beater 7. The dust removal screen plate 12 is provided with a plurality of mesh holes to allow impurities to pass through. To improve the impurity removal effect, the dust removal screen plate 12 is configured in an arc shape that matches the beater 7 and contacts the upper side wall of the beater 7. Through the compression between the beater 7 and the dust removal screen plate 12, impurities in the backflow are removed and discharged through the first dust collection outlet.

[0048] The first dust removal knife group 9 is arranged on the lower front side of the beater 7, and its front end is connected to the front end of the beater 7 to ensure that the beater 7 can directly bring the cotton in the cotton inlet channel 6 into the first dust removal knife group 9 for dust removal after twisting it.

[0049] The second dust removal knife group 10 is arranged at the lower rear side of the beater 7, and the rear end is simultaneously connected to the rear end of the beater 7 and the end of the cotton outlet channel 8, so that the cotton after dust removal can be directly fed into the cotton outlet channel 8. Among them, unlike the prior art, the front end of the second dust removal knife group 10 is connected to the rear end of the first dust removal knife group 9. The two can be connected by a tool or directly connected, and finally form an arc structure that cooperates with the side of the beater 7. Through the squeezing of the beater 7 and the first dust removal knife group 9 and the second dust removal knife group 10 respectively, the cotton is better dusted.

[0050] It should be noted that in the front-to-back direction, the length of the second dust removal knife group 10 is greater than that of the first dust removal knife group 9, so that compared with the prior art, the number of knives is increased, thereby enhancing the combing and impurity removal function.

[0051] In this embodiment, the tool includes a tool holder, a connecting block 14 and a triangular dust removal rod 13. The tool holder is mounted on the machine body 2, the connecting block 14 is mounted on the tool holder, and the triangular dust removal rod 13 is movably mounted on the upper end of the connecting block 14 for removing impurities from cotton, and the triangular dust removal rod 13 can rotate relative to the connecting block 14. During installation, all the tools are arranged in a fan-shaped pattern along the shape of the first dust removal knife group 9 and the second dust removal knife group 10, with the triangular dust removal rod 13 on the side close to the beater 7 and the triangular dust removal rod 13 on the side away from the beater 7. Since the tools are distributed in a fan-shaped pattern, the distance between the connecting blocks 14 of two adjacent tools is greater than the distance between the triangular dust removal rods 13.

[0052] The upper opening of the impurity discharge channel 11 is connected to the first dust removal blade assembly 9 and the second dust removal blade assembly 10, and the lower end extends to the bottom of the machine body 2, forming a second dust collection outlet 15. The impurity discharge channel 11 has a Y-shaped structure with a larger upper opening area than the lower opening area. In this embodiment, the upper opening of the impurity discharge channel 11 covers the cross-section of the machine body 2 to better receive impurities that fall from the first dust removal blade assembly 9 and the second dust removal blade assembly 10.

[0053] A dust removal fan 16 is further provided in the machine body 2 , and the dust removal fan 16 is arranged beside the second dust collecting outlet 15 .

[0054] A dust collecting waste roller 17 is provided in the impurity discharge channel 11 near the second dust collecting waste outlet 15 .

[0055] Example 2

[0056] A soft loosening airflow type cotton cleaning machine, refer to Figure 5-Figure 6 The difference from the first embodiment is that a combing plate 18 is further provided between the first dust removal knife group 9 and the second dust removal knife group 10. The combing plate 18 can further comb and disperse the cotton beaten by the first dust removal knife group 9, effectively separate the fibers from impurities, and prevent the generation of cotton knots. The cotton is then handed over to the second dust removal knife group 10 for further impurity removal, so that the second dust removal knife group 10 can play a better role and maximize its impurity removal efficiency.

[0057] In addition, the first dust removal blade set 9 , the second dust removal blade set 10 and the needle plate 18 can all be moved independently to move away from or closer to the beater 7 .

[0058] Specifically, a fixed plate 19 is installed on the body 2 at positions corresponding to the first dust removal knife group 9, the second dust removal knife group 10 and the combing needle plate 18, and the knife holder and the combing needle plate 18 are slidably connected to the fixed plate 19 through multiple sliding components.

[0059] Each sliding assembly includes a piston cylinder 20 and a piston rod 21. The tool holder and the needle plate 18 are respectively connected to the corresponding piston rod 21. The piston cylinder 20 is mounted on the fixed plate 19, and the piston rod 21 can slide freely within the piston cylinder 20. Furthermore, the piston cylinder 20 and the piston rod 21 are arranged in a fan-shaped distribution along the curved contour of the tool holder so that the distance between them and the beater 7 is consistent. This allows the tool to adjust the distance between it and the beater 7 without changing the angle during movement. That is, the sliding direction is consistent with the radial direction of the beater 7.

[0060] When cotton is blocked between the beater 7 and the first dust removal knife group 9, the second dust removal knife group 10 and the combing needle plate 18, the first dust removal knife group 9, the second dust removal knife group 10 or the combing needle plate 18 at the blocked position automatically drives the piston rod 21 to move under the pressure of the cotton, and the distance from the beater 7 becomes larger, so that the cotton can pass normally and the triangular dust removal rod 13 is protected from damage.

[0061] In order to enable the first dust removal blade group 9, the second dust removal blade group 10 and the combing plate 18 to automatically reset, a spring (not shown in the figure) is provided in the piston cylinder 20. The spring has a pre-tightening force that drives the piston rod 21 to move toward the side close to the beater 7. When the clogged cotton passes through, the piston rod 21 moves out of the piston cylinder 20 under the action of the spring, and drives the first dust removal blade group 9, the second dust removal blade group 10 and the combing plate 18 to automatically return to their initial positions close to the beater 7.

[0062] In actual use, the first dust removal blade group 9, the second dust removal blade group 10 and the spacing between the combing plate 18 and the beater 7 can also be manually adjusted according to specific circumstances.

[0063] The technical features of the above embodiments can be combined arbitrarily (as long as there is no contradiction in the combination of these technical features). In order to make the description concise, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be considered to be within the scope of this specification.
