AI Technical Summary
Existing cotton picking rollers fail to completely unload cotton during the unloading process, lacking an effective shaking unloading mechanism, resulting in low picking efficiency.
The cotton picking drum is equipped with swingable cotton picking needles. The needles release their energy by moving up and down the connecting rod. Combined with the design of the forked groove and the annular opening, the cotton is shaken and unloaded. Gas is sprayed out through the air pipe to assist the cotton in detaching.
This enables rapid and complete unloading of cotton, improves harvesting efficiency, ensures cotton detaches smoothly from the picking needle, and reduces residue.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cotton harvesting technology, specifically relating to a cotton harvesting roller for a cotton harvester. Background Technology
[0002] Cotton is one of the world's major crops. Cotton fibers can be made into fabrics of various specifications. During the cotton harvest season, most cotton is picked using roller harvesters. Compared with manual picking, machine roller harvesting is more efficient and can save a lot of picking time and labor.
[0003] In existing cotton picking rollers, the roller and the cotton picking needle are usually welded and fixed together. When cotton gets stuck on the cotton picking needle, some cotton is not completely unloaded during unloading. There is a lack of cotton picking rollers for cotton harvesters that can shake during unloading to facilitate quick unloading of cotton. Utility Model Content
[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a cotton picking roller for a cotton harvester. The surface of the roller is provided with swingable cotton picking needles. When the cotton picking needles reach a specific position, the connecting rod can move up or down, so that the cotton picking needles can store force and release it after reaching a certain position, which facilitates shaking the cotton.
[0005] A cotton picking drum for a cotton harvester includes a drum body. A rotating groove is formed on one side of the drum body, and cotton picking needles are rotatably disposed on the surface of the rotating groove. A connecting groove is formed on one side of the cotton picking needles, and a connecting rod is attached to the surface of the connecting groove. The connecting rod is slidably disposed inside the drum body. A mounting frame is rotatably disposed on one side of the drum body, and a driving block is integrally disposed inside the mounting frame. A forked groove is formed on the outer side of the driving block, and a forked block is rotatably disposed on the surface of the forked groove. The connecting rod is attached to the surface of the forked groove, and a tension spring is disposed between the connecting rod and the drum body.
[0006] The beneficial effects of the above technical solution are as follows:
[0007] This design features a cylinder surface equipped with swingable cotton-picking needles. When the needles reach a specific position, the connecting rod moves up or down, allowing the needles to accumulate power and release it, thus facilitating the shaking of the cotton. The design also incorporates a bifurcated groove that guides the cotton-picking needles in two directions. During the shaking process, an annular nozzle ejects gas, and the rotation of the toothed ring moves the control frame up and down, adjusting the position of the top ring to control the direction of the gas ejection from the annular nozzle, corresponding to the shaking direction of the cotton-picking needles and facilitating the falling of cotton.

[0013] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 4 The embodiments are described in detail below.
[0014] This embodiment provides a cotton picking roller for a cotton harvester, as shown in the attached figure. Figure 1-4 As shown, the instruction manual is attached. Figure 1 This is a three-dimensional structural diagram of the solution, attached to the instruction manual. Figure 2 Cut along the middle section using cotton-picking needle 3. (Instruction manual attached) Figure 3 The part being cut is forked block 9; the instruction manual is included. Figure 4The cutting is performed on the side tube 13. The cylinder 1 is rotatably mounted on the mounting frame 6, which represents part of the cotton picking equipment. Since the cotton picking roller is not used alone, a drive gear 18 is provided on one side of the cylinder 1. A motor can be installed on one side of the drive gear 18 to make the cylinder 1 rotate on the mounting frame 6. Therefore, the cylinder 1 can rotate. A driving block 7 is integrally provided below the mounting frame 6 (the position of the driving block 7 does not correspond to the position during picking; the driving block 7 is located at the cotton unloading position). A forked groove 8 is opened on one side of the driving block 7. A connecting rod 5 overlaps on the surface of the forked groove 8. The connecting rod 5 passes through the inside of the cylinder 1 to one side of the mounting frame 6. The connecting rod 5 overlaps on the connecting groove 4 inside the cylinder 1. The connecting groove 4 is opened on one side of the cotton picking needle 3. A rotating groove 2 is opened on one side of the cylinder 1. The cotton picking needle 3 is rotatably mounted on the surface of the rotating groove 2 (the rotating groove 2 has a shape restriction, so that the cotton picking needle 3 can only rotate up and down). The connecting rod 5 is slidably disposed inside the cylinder 1, and has a tension spring 10 at its bottom. The up-and-down movement of the connecting rod 5 causes the cotton-picking needle 3 to rotate up and down. If the connecting rod 5 is moved upwards or downwards, it is released instantaneously, allowing the cotton-picking needle 3 to release quickly and achieve a shaking effect. Therefore, this design includes a driving block 7, with a bifurcated groove 8 on its outer side. A rotating bifurcated block 9 is located at the bifurcation of the bifurcated groove 8. The tail of the bifurcated block 9 is a small gear, which meshes with a gear ring 11. The gear ring 11 is rotatably disposed in the middle of the mounting bracket 6. Since this design has multiple bifurcated blocks 9, only one end of one bifurcated block 9 needs a motor to rotate the gear ring 11 and drive multiple bifurcated blocks 9 to operate in conjunction. The motor in this design is a servo motor, which can achieve self-locking of the motor shaft when stopped. When the cylinder 1 rotates, the connecting rod 5 rotates along with it, as shown in the attached instruction manual. Figure 1 As shown, the cylinder 1 rotates counterclockwise at this time, and the connecting rod 5 will enter the bifurcation groove 8. Since the bifurcation block 9 can rotate, as... Figure 1With the forked block 9 stationary, the connecting rod 5 slides relative to the cylinder 1 (because the forked groove 8 pushes the connecting rod 5 upwards). As the connecting rod 5 moves upwards, the forked groove 8 reaches a certain position and becomes suspended, effectively releasing the connecting rod 5. Therefore, the connecting rod 5 quickly rebounds under the action of the tension spring 10. The cotton-picking needle 3 is attached to the connecting rod 5, causing it to rotate rapidly, achieving a shaking effect. Similarly, if the forked block 9 rotates 90 degrees clockwise, the connecting rod 5 will be squeezed downwards, releasing the cotton-picking needle 3 and allowing it to shake in different directions. This is the split... The purpose of the fork groove 8 is to allow the cotton-picking needle 3 to rotate and store energy in one direction, then release it, causing the cotton on the needle 3 to shake and detach. An air supply pipe 12 is installed inside the cylinder 1, with an outer connecting pipe 21 inserted above it. The outer connecting pipe 21 and the air supply pipe 12 are sealed and rotated together, requiring a sealing ring on the edge of the outer connecting pipe 21. One end of the outer connecting pipe 21 needs to be connected to a blower (or air compressor). The blower blows air into the outer connecting pipe 21, allowing air to pass through the air supply pipe 12. Side pipes 13 are connected to both the upper and lower sides of the air supply pipe 12. The other side of the side tube 13 is connected to the annular opening 14. The annular opening 14 also has two sides, upper and lower. The two sets of annular openings 14 correspond to the shaking direction of the cotton picking needle 3. This way, once the annular opening 14 sprays gas, it is easy for the cotton to detach. In this solution, the upper or lower side of the annular opening 14 is controlled by the toothed ring 11. The inner side of the toothed ring 11 has an arc-shaped groove 15. The arc-shaped groove 15 is spiral in shape. A vertical bar 16 is slidably arranged in the middle of the mounting frame 6. The top of the vertical bar 16 overlaps the arc-shaped groove 15. As the toothed ring 11 rotates, the vertical bar 16 can slide up and down on the mounting frame 6. The bottom of the vertical bar 16 overlaps with the control frame 17, and an opening is provided at the top of the control frame 17. The bottom of the vertical bar 16 overlaps with the top of the control frame 17, so that the rotation of the control frame 17 with the cylinder 1 does not affect the vertical bar 16's ability to move the control frame 17 up and down. The middle part of the control frame 17 extends into the interior of the gas supply pipe 12 and is fixedly connected to a top ring 19 (to facilitate the sliding of the control frame 17, a through groove is provided at the edge of the gas supply pipe 12, and the top ring 19 covers the through groove when it moves up and down, so that the through groove will not leak). The top ring 19 (the top ring 19 and the bottom ring 20 are connected together by a long rod) Figure 4The upper annular opening 14 is blocked, while the lower annular opening 14 is not blocked by the bottom ring 20. When the control frame 17 moves downward, the top ring 19 opens the upper annular opening 14, and the bottom ring 20 blocks the lower annular opening 14. This causes the gear ring 11 to adjust the air jet position during rotation, corresponding to the bifurcation block 9, which causes the connecting rod 5 to move upward or downward. A rotating groove 2 is provided on one side of the cylinder 1, and a cotton picking needle 3 is rotatably mounted on the surface of the rotating groove 2. A connecting groove 4 is provided on one side of the cotton picking needle 3, and a connecting rod 5 overlaps on the surface of the connecting groove 4. The connecting rod 5 is slidably mounted inside the cylinder 1. A mounting frame 6 is rotatably mounted on one side of the cylinder 1, and a driving block 7 is integrally mounted inside the mounting frame 6. A bifurcation groove 8 is provided on the outer side of the driving block 7, and a bifurcation block 9 is rotatably mounted on the surface of the bifurcation groove 8. A connecting rod 5 overlaps on the surface of the bifurcation groove 8, and a tension spring 10 is provided between the connecting rod 5 and the cylinder 1. A toothed ring 11 is rotatably mounted on the upper surface of the mounting frame 6. A forked block 9 is engaged on the surface of the toothed ring 11. An air supply pipe 12 is provided in the middle of the cylinder 1. A side pipe 13 is connected to one side of the air supply pipe 12. An annular opening 14 is provided on the outer side of the cylinder 1. A side pipe 13 is connected to one side of the annular opening 14. An arc groove 15 is provided on the inner arc of the toothed ring 11. A vertical bar 16 overlaps on the surface of the arc groove 15. The vertical bar 16 is slidably mounted on the surface of the mounting frame 6. A control frame 17 is slidably mounted on one side of the cylinder 1. A vertical bar 16 overlaps on one side of the control frame 17. A top ring 19 is integrally mounted on the lower side of the control frame 17. A bottom ring 20 is integrally mounted on the lower surface of the top ring 19. An outer pipe 21 is rotatably mounted on the upper surface of the air supply pipe 12. Through grooves 22 are provided on both sides of the air supply pipe 12. There are multiple cotton picking needles 3. A drive gear 18 is integrally mounted on one side of the cylinder 1. A motor is mounted on one side of the forked block 9.
