[0002] A cotton harvester is a mechanical device specifically designed for harvesting cotton. It significantly improves cotton harvesting speed and quality while reducing labor costs. The internal structure of a cotton harvester is complex, with each key component playing a crucial role. The harvesting process involves the cotton plants entering the picking chamber, being surrounded and pressed by horizontal grids and pressure plates, then the picking spindles rotating along the drum to pick the seed cotton. Finally, the cotton is stripped by a stripping disc and collected in the cotton collection chamber.

[0003] In actual use, the harvested cotton contains a large number of fruit branches and boll husks, which are directly mixed into the cotton, resulting in an increased impurity content and affecting the quality of the cotton. This necessitates extensive cleaning work before subsequent processing, thereby reducing processing efficiency. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a cotton cleaning device for a cotton harvester to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A cotton cleaning device for a cotton harvester includes a cotton harvester, a cleaning box fixedly connected to the top of the cotton harvester, a cleaning component and a feeding mechanism installed inside the cleaning box, and the feeding mechanism installed below the cleaning component.

Spike rollers 7 are fixedly connected to the outer sides of both the first gear 5 and the second gear 6. The spike rollers 7 are rotatably connected to the inside of the cotton picker 1. Multiple spikes 8 are fixedly connected to the outer side of the spike rollers 7. A baffle 9 is fixedly connected to one side of each spike roller 7. A second variable frequency motor 10 is fixedly connected to one side of the cleaning box 2. A third gear 11 is fixedly connected to the output end of the second variable frequency motor 10. The third gear 11 meshes with one side of the second gear 6. There is a fourth gear 12, and a rotating shaft 13 is fixedly connected inside the fourth gear 12 and the third gear 11. Multiple cotton-pulling teeth 14 are fixedly connected to the outside of the rotating shaft 13. Two third variable frequency motors 15 are fixedly connected to one side of the cleaning box 2. The output end of the third variable frequency motor 15 is fixedly connected to the cotton-pulling roller 16. The two spiked rollers 7 drive multiple opposing rotations. The cotton is first hit by the two spiked rollers 7, so that the large impurities mixed in are initially removed. Then, the cotton-pulling teeth 14 driven by the two rotating shafts 13 hit the cotton again, which can comb the cotton in multiple directions, enhance the impact force on the cotton, make it easier for impurities to fall off the cotton, reduce dead corners in the cleaning process, and reduce the accumulation of impurities.

[0020] Reference Figure 3 and 5 As shown, the feeding mechanism includes a blower 17, with an air conveying pipe 18 connected to the output end of the blower 17. One end of the air conveying pipe 18 is connected to an air conveying box 19. A discharge port is provided on one side of the cleaning box 2. A screen plate 20 is fixedly connected to the bottom of the air conveying box 19. The screen plate 20 is fixedly connected to the inside of the cleaning box 2. Two inclined plates 21 are fixedly connected to the top of the screen plate 20. A vibrating motor 22 is fixedly connected to the bottom of the screen plate 20. Multiple springs 23 are fixedly connected to the bottom of the screen plate 20. Guide cylinders 24 are fixedly connected to the bottom of the springs 23. The bottom of the cleaning box 2 is connected to the discharge pipe 25, and the discharge pipe 25 is fixedly connected to the butterfly valve 26. The vibration motor 22 and multiple springs 23 work together to drive the screen plate 20 to vibrate, which helps the cotton to loosen and stratify on the screen plate, making it easier to separate impurities from the cotton. At the same time, the air box 19 can blow the cotton on the screen plate 20. The slope of the two inclined plates 21 provides guidance so that the cotton can move quickly to the discharge port, thereby improving the discharge efficiency.

[0021] Working principle of this utility model: This utility model designs a cotton cleaning device for a cotton harvester, the specific structure of which is shown in the attached instruction manual. Figure 1-7As shown, in this technical solution, through the cooperation of various structures, when the cotton needs to be coarsely cleaned, the cotton harvester 1 transports the harvested cotton into the cleaning box 2, and then simultaneously starts the first variable frequency motor 4, the second variable frequency motor 10, and two third variable frequency motors 15. Utilizing the inclined action of the feed plate 3, the cotton falls between the two spiked rollers 7. Then, the first variable frequency motor 4 drives the first gear 5 to rotate, causing the first gear 5 to mesh and drive the second gear 6 to rotate. This allows the first gear 5 and the second gear 6 to drive the two spiked rollers 7 to rotate in opposite directions. The two spiked rollers 7 and multiple spikes 8 can then be used to initially loosen and strike the cotton. The cotton is cleaned, and large impurities mixed in are removed. Due to the difference in quality between the cotton and the impurities, the impurities fall off before the cotton. At the same time, the second variable frequency motor 10 drives the third gear 11 to mesh with the fourth gear 12 to rotate. The third gear 11 and the fourth gear 12 can drive multiple cotton-picking teeth 14 to rotate through the rotating shaft 13. The two cotton-picking teeth 14 can further comb and beat the cotton. At the same time, two third variable frequency motors 15 are started, and the two third variable frequency motors 15 drive the cotton-picking roller 16 to rotate in the opposite direction to the two rotating shafts 13, so that the cotton on the cotton-picking teeth 14 can be swept off onto the screen plate 20. When cotton needs to be fed, the blower 17 is started. The blower 17 can deliver air to the air box 19 through the air pipe 18. The slope of the screen plate 20 and the guiding effect of the cross-section of the two inclined plates 21 can make the air deliver the cotton to the discharge port. At the same time, the vibration motor 22 is started. The vibration motor 22 and multiple springs 23 work together to drive the screen plate 20 to vibrate up and down inside the cleaning box 2. Multiple guide cylinders 24 can provide guidance through the springs 23. The vibration of the screen plate 20 can make the impurities on the screen plate 20 fall into the inside of the cleaning box 2 and shake the cotton to the discharge port to facilitate the feeding of cotton.
