The hook-toothed rack 12 is fixedly connected to the roller 11 by welding and rotates synchronously with the roller 11. This allows the hook-toothed rack 12 to rotate together with the roller. During the rotation of the hook-tooth roller 1, the residual cotton on the cotton stalks is wrapped around the hook-tooth strip 12 and rotates with the hook-tooth roller 1. The cotton stalks slide out of the roller due to gravity, thus completing the collection. The residual cotton collection mechanism 2 includes a brush suction cylinder 21 and a connecting pipe 22. The brush suction cylinder 21 extends into the inner cavity of the roller 11. The head and tail of the brush suction cylinder 21 are respectively provided with a first connecting through hole 211.

During the rotation of the hook-tooth roller 1, the hook-tooth strip 12 contacts the nylon brush 212. The waste cotton wrapped on the hook-tooth strip 12 is separated from the hook-tooth strip 12 under the action of the nylon brush 212. Under the action of the negative pressure fan 233, it is sucked into the brush suction cylinder 21 and enters the waste cotton collection box 23 under the action of negative pressure airflow, realizing the separation of waste cotton.

[0037] The support structure 4 includes a connecting frame 41, a bearing seat 43, and a cylindrical roller bearing 44. The base 6 includes a base 61, on which a bearing support steel bar 62 is mounted. A bearing seat 43 is mounted on the bearing support steel bar 62, and a cylindrical roller bearing 44 is mounted on the bearing seat 43. The base 61, bearing support steel bar 62, and bearing seat 43 are connected and fixed together by the connecting frame 41 and bolts 42. A motor support seat 64 is mounted on the base 61, and the base 61 and motor support seat 64 are fixed together by welding. Side baffles 63 are connected to both sides of the base 61. The motor support seat 64 is bolted together to fix the motor 7.

The side of the suspension mechanism 9 away from the second connecting through hole 621 is connected to the chain 8 through a first connecting through hole 211. This ensures that the hook rack 12 passes through the nylon brush 212 to achieve residual cotton recycling.

[0038] The transmission mechanism 3 includes a transmission shaft 31, on which a first flat key 33 is provided, causing the first rubber wheel 32 to rotate together with the transmission shaft 31. A first sleeve 34 is provided on the transmission shaft 31, with the first rubber wheel 32 attached to one end of the sleeve 34. A cylindrical roller bearing 44 is connected to the end of the sleeve 34 away from the first rubber wheel 32, and a sprocket 35 is provided at the other end of the transmission shaft 31. The sprocket 35 is connected to a chain 8, and the other end of the chain 8 is connected to a motor 7. The motor 7 transmits power to the transmission mechanism 3 via chain drive. The hook-tooth roller 1 contacts the first rubber wheel 32 through a retaining ring 111. Under the action of friction, the transmission mechanism 3 drives the hook-tooth roller 1 to rotate. A positioning pin 37 is provided on the transmission shaft 31 near the sprocket 35, and a limit sleeve 36 is fixedly connected to the transmission shaft 31 through the positioning pin 37. The driven mechanism 5 includes a driven shaft 51, on which a second key 53 is provided. A second rubber wheel 52 is connected to the driven shaft 51 via the second key 53. A second sleeve 54 is provided on the driven shaft 51, with the second rubber wheel 52 located at one end of the second sleeve 54. The end of the second sleeve 54 away from the second rubber wheel 52 is connected to a cylindrical roller bearing 44. The hook-tooth roller 1 contacts the second rubber wheel 52 via a retaining ring 111. There is friction between the driven mechanism 5 and the hook-tooth roller 1. Under the action of friction, the driven mechanism 5 rotates with the hook-tooth roller 1.

[0039] The working principle of this cotton stalk recycling device that can separate cotton stalks from residual cotton is as follows: The motor 7 transmits torque to the sprocket 35 via the chain 7. The sprocket 35 drives the transmission shaft 31 to rotate via the first flat key 33. The first rubber wheel 32 rotates along with the transmission shaft 31 under the action of the first flat key 33. The roller 11 contacts the first rubber wheel 32, and the significant friction causes the entire hook-tooth roller 1 to rotate. The roller 11 contacts the second rubber wheel 52, and the friction drives the driven mechanism 5 to rotate. The driven mechanism 5 supports the hook-tooth roller 1 while converting the friction into torque, reducing energy loss during the rotation of the hook-tooth roller 1. The cotton stalks enter the roller 1 from the higher end. Under the action of the roller 11 and the hook-tooth strip 12, the cotton stalks move within the hook teeth. When the angle is appropriate and the residual cotton on the cotton stalks contacts the hook-tooth strip 12, the residual cotton will wrap around the tip of the hook-tooth strip and the barbs. The contact between cotton stalks and residual cotton typically occurs after the cotton stalks are cut by the harvester, with the protruding hard fibers at the ends hooking and entangled with the fallen cotton. As the hook-toothed roller 1 rotates, the angle at the connection point between the residual cotton and the cotton stalk changes, and the separation condition changes from breaking the residual cotton fibers to overcoming the friction between the residual cotton and the cotton stalk. This weakens the connection between the residual cotton fibers and the cotton stalk, and under the influence of gravity, the cotton stalk separates from the residual cotton. The cotton stalk that has separated from the residual cotton slides out of the hook-toothed roller 1.

[0040] After the residual cotton is separated from the cotton stalk, it remains wrapped around the hook toothed strip 12. The residual cotton rotates with the hook toothed roller 1. When it rotates counterclockwise and comes into contact with the nylon brush 212, the residual cotton continues to rotate counterclockwise under the action of the hook toothed strip 12, causing the nylon brush 212 to deform. At the same time, the hook tooth angle is close to horizontal, and the connection force between the hook toothed strip 12 and the residual cotton decreases. When the elasticity of the nylon brush 212 exceeds the separation force between the residual cotton and the hook toothed strip 12, the residual cotton is brushed off the hook toothed strip and, under the negative pressure airflow generated by the negative pressure fan 233, enters the brush exhaust air suction cylinder 21 through the air suction port 214 and is transported to the residual cotton collection box 23 through the connecting pipe 22 to achieve the collection of residual cotton.

[0041] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
