Description

Technical Field

[0001] This invention relates to the field of cotton harvester cleaning technology, specifically to a device for cleaning the spindle rod of a cotton harvester. Background Technology

[0002] The cotton picker spindle is one of the core components of the cotton picker. It is mainly used to separate the cotton fibers from the cotton boll when picking cotton. Its structure usually includes a rod-shaped body with a bevel gear at one end and a cone at the other end. The surface is covered with straight grooves and cotton-hooking teeth. The cotton fibers are removed by rotating and stirring the cotton boll.

[0003] During cotton harvesting, the picking rods of cotton harvesters are in constant contact with cotton fibers, branches, leaves, soil and other impurities. The surface is prone to stubborn dirt such as cotton wax, dust and plant sap. If cleaning is not thorough, it will not only reduce the efficiency of subsequent cotton harvesting, but also accelerate the wear of the picking rods and affect their service life. Therefore, it is necessary to clean the picking rods regularly.

[0004] Currently, common methods for cleaning bar removal rods mainly involve fixed spraying or manual rinsing. These methods have low automation levels, rely heavily on manual adjustment of clamping force and spray angle, resulting in low efficiency and difficulty in adapting to batch operations. Furthermore, many clamps are single-point clamping or manually adjustable, leading to poor stability of the clamping mechanism and difficulty in ensuring the concentricity of the bar removal rod during the cleaning process. This can easily cause uneven cleaning or damage to the rod. In addition, existing spray heads are mostly arranged in a single row with insufficient cleaning coverage, failing to effectively cover the complex surface structure of the bar removal rod and easily creating cleaning dead zones. Summary of the Invention

[0005] The purpose of this invention is to provide a cleaning device for the spindle rod of a cotton harvester, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a cleaning device for the spindle rod of a cotton harvester, comprising a cleaning body, a cleaning chamber located in the middle of the cleaning body, a door located at the front end of the cleaning body corresponding to the cleaning chamber, a clamping mechanism connected to the middle of the cleaning chamber, a set of flushing mechanisms located at the middle of both the left and right sides of the cleaning chamber, a drain trough located at the bottom of the cleaning chamber, a drain pipe connected to the bottom of the drain trough, the other end of the drain pipe extending to the outer end of the cleaning body, and a door located at the front end of the cleaning body corresponding to the drain trough;

[0007] The clamping mechanism includes a connecting base plate. A set of connecting base plates is provided at the front and rear positions of the top of the cleaning chamber. A set of fastening mechanisms is connected to the bottom of the two sets of connecting base plates. An inner tube is provided at the rear middle of the cleaning chamber, and the inner tube extends to the middle of the two sets of fastening mechanisms.

[0008] By adopting the above technical solution, the clamping mechanism can fix the spindle removal rod in the center of the cleaning chamber, ensuring that the spindle removal rod does not shift during the cleaning process, ensuring uniform cleaning, and avoiding collision damage. The two sets of flushing mechanisms on the left and right can simultaneously flush the spindle removal rod in both directions, expanding the coverage area, effectively removing residual impurities, and improving cleaning efficiency. The drain trough and drain pipe form a closed drain channel, and the waste liquid and impurities after cleaning can be discharged in a concentrated manner to avoid secondary pollution. Door 1 facilitates the removal and placement of the spindle removal rod, and door 2 facilitates the quick cleaning of accumulated dirt in the drain trough, ensuring smooth drainage and avoiding blockage. The two sets of fastening mechanisms are located at the front and rear of the cleaning chamber, respectively, and can simultaneously clamp the front and rear ends of the spindle removal rod to ensure its stability during the cleaning process and avoid shaking or shifting. The spindle removal rod fastening mechanism is fixed in the center of the cleaning chamber, ensuring that the water flow from the flushing mechanisms on both sides evenly covers the surface of the rod and avoids cleaning dead corners. At the same time, the inner tube extends to the middle of the two sets of fastening mechanisms and can extend to the inner end of the spindle removal rod to clean its interior. It works in conjunction with the flushing mechanism to perform synchronous cleaning inside and out, improving the cleaning effect.

[0009] Preferably, each of the two sets of connecting substrates has a connecting notch at its bottom center, and each connecting notch has an inner groove at its top center. The two sets of connecting substrates are connected to each other via a drive shaft. The front and rear ends of the drive shaft extend into the inner grooves and are connected to a gear. A gear is provided at the outer center of the drive shaft, and a gear is connected to the top of the gear and to the rear center of the gear. A drive motor is connected to the gear.

[0010] By adopting the above technical solution, the drive motor drives the gear three to rotate, and the two sets of gears one are driven to rotate synchronously through the gear two and the transmission shaft, which facilitates the synchronous drive of the fastening mechanism. At the same time, the gear one is embedded in the inner groove one, and the gear two and gear three are compactly arranged, which can effectively reduce external interference, reduce the risk of wear, and extend the service life.

A set of racks is provided at the inner side of the inner wheel corresponding to the inner grooves.

[0014] By adopting the above technical solution, the drive motor 2 drives the rack through the gear 4, thereby precisely controlling the rotation of the inner wheel, and clamping and fixing the spindle rod through the linkage mechanism 1. The power transmission is direct and efficient, the inner wheel responds quickly, which can reduce the waiting time of the cleaning process and is suitable for high-frequency operation.

[0015] Preferably, the linkage mechanism includes a through groove, a clamping block, a central shaft, a connecting arm, and a central groove. A set of through grooves is provided at the inner end of the turntable corresponding to the four ends of the inner wheel. A set of clamping blocks is provided in each through groove. The clamping blocks are connected to the inner side of the inner wheel through a set of connecting arms. A central shaft is provided at the middle end of each through groove. A central groove corresponding to the central shaft is opened at the inner end of the connecting arm.

[0016] By adopting the above technical solution, the four sets of linkage mechanisms are evenly distributed to form four-point synchronous clamping, ensuring that the force on the unloading rod is uniform and avoiding deformation or damage caused by stress concentration at a single point. The drive motor drives the inner wheel to rotate through the rack and pinion, and drives the clamping block to move radially in sync through the four sets of connecting arms, which can realize rapid concentric clamping or loosening.

[0017] Preferably, the components of the two sets of flushing mechanisms are identical. The flushing mechanism includes a movable groove, an expansion groove, a third drive motor, a second linkage mechanism, an inner plate, nozzles, and a water supply pipe.

[0018] By adopting the above technical solution, the drive motor three drives the inner plate to swing back and forth in the cleaning chamber through the linkage mechanism two, so that the water flow coverage area presents dynamic changes and forms a cross water curtain coverage, ensuring that there are no dead corners for cleaning on the surface of the spindle removal rod.

The other end of the spring is connected to a fourth linkage arm. The other ends of the first and second sets of fourth linkage arms are connected to the front and rear ends of the inner plate.

[0020] By adopting the above technical solution, the drive motor three drives the linkage arm one to reciprocate around the middle end through the linkage arm two, thereby driving the inner plate to reciprocate inside the cleaning chamber. The linkage arm three can limit the rear end of the inner plate, improve the stability of the inner plate when it moves, change the flushing and cleaning angle of the spindle bar, improve cleaning efficiency, and avoid dead corners.

[0021] Preferably, the nozzles are arranged in two rows, one above the other, with the two rows of nozzles staggered.

[0022] By adopting the above technical solutions, the coverage area of ​​the spray nozzles can be expanded, and the cleaning effect can be improved.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. This invention uses two sets of connecting base plates located at the front and rear of the top of the cleaning chamber. The two sets of connecting base plates are connected by a transmission shaft. The transmission shaft can be rotated by a drive motor, and the two sets of fastening mechanisms are synchronously driven by the transmission shaft and gear pair. This eliminates the eccentric torque caused by traditional single-sided drive, and can achieve precise synchronous action of the front and rear fastening mechanisms. It avoids mutual interference between the front and rear fastening mechanisms, which would affect the clamping and movement of the spindle rod.

[0027] 2. The present invention uses a fastening mechanism set at the bottom of the connecting substrate. The fastening mechanism includes components such as a turntable, a toothed rod, a central hole, an inner wheel, and a linkage mechanism. The turntable can drive the spindle removal rod to reciprocate at the bottom of the connecting substrate through the meshing of the toothed rod and the gear. This optimizes the fixed cleaning method of the traditional cleaning device, can change the cleaning angle of the spindle removal rod, expand the cleaning surface, and has greater flexibility, which can significantly improve the cleaning effect.

[0028] 3. This invention utilizes two sets of flushing mechanisms located at the left and right ends of the cleaning chamber. Each flushing mechanism includes a movable groove, an expansion groove, a third drive motor, a second linkage mechanism, an inner plate, a nozzle, and a water supply pipe. These components work together to drive the inner plate and nozzle to move up and down on the left and right sides of the cleaning chamber, changing the flushing direction on the spindle rod and achieving dynamic coverage cleaning. Compared to traditional fixed cleaning methods, this mechanism effectively improves the flexibility of cleaning, forms a cross water curtain coverage, ensures that there are no dead corners on the surface of the spindle rod, and improves cleaning efficiency.

[0038] To further explain the technical solution of the present invention, a detailed description is provided below through specific embodiments.

[0039] Please see Figure 1 This invention provides a cleaning device for the spindle rods of a cotton harvester, comprising a cleaning body 1, a cleaning chamber 2 located in the middle of the cleaning body 1, the left and right sides of the cleaning chamber 2 being arc-shaped, a door 3 installed at the front end of the cleaning body 1 corresponding to the cleaning chamber 2, a clamping mechanism 4 connected to the middle of the cleaning chamber 2 for clamping and fixing the spindle rod, a set of flushing mechanisms 5 located at the middle of the left and right sides of the cleaning chamber 2, a sewage trough 6 located at the bottom of the cleaning chamber 2, a sewage pipe 7 connected to the bottom of the sewage trough 6, the other end of the sewage pipe 7 extending to the outer end of the cleaning body 1 to discharge the sewage and waste generated during cleaning, and a set of doors 8 installed at the front end of the cleaning body 1 corresponding to the position of the sewage trough 6 to facilitate cleaning of the sewage trough 6.

[0040] Specifically, the clamping mechanism 4 can fix the spindle removal rod in the center of the cleaning chamber 2, ensuring that the spindle removal rod does not shift during the cleaning process, ensuring uniform cleaning, and avoiding collision damage. The two sets of flushing mechanisms 5 on the left and right can simultaneously flush the spindle removal rod in both directions, expanding the coverage area, effectively removing residual impurities, and improving cleaning efficiency. The drain trough 6 and the drain pipe 7 form a closed drain channel, and the waste liquid and impurities after cleaning can be discharged in a concentrated manner to avoid secondary pollution. The first door 3 facilitates the picking and putting away of the spindle removal rod, and the second door 8 facilitates the quick cleaning of the accumulated dirt in the drain trough 6, ensuring smooth drainage and avoiding blockage.

[0041] Please see Figure 1-Figure 2The clamping mechanism 4 includes a connecting base plate 41. A set of connecting base plates 41 are fixedly connected to the front and rear positions of the top of the cleaning chamber 2. A set of fastening mechanisms 42 are installed at the bottom of the two sets of connecting base plates 41. An inner tube 43 is installed in the middle of the rear of the cleaning chamber 2. The inner tube 43 extends to the middle of the two sets of fastening mechanisms 42. The rear end of the inner tube 43 extends through to the rear end of the cleaning body 1 and can be connected to an external water source. When the spindle removal rod is inserted into the middle of the two sets of fastening mechanisms 42, the inner tube 43 can extend to the inner end of the spindle removal rod. The outer side of the inner tube 43 is provided with no less than two sets of water outlets, which can clean the inside of the spindle removal rod.

[0042] Specifically, the two sets of fastening mechanisms 42 are located at the front and rear of the cleaning chamber 2, respectively, and can simultaneously clamp the front and rear ends of the spindle removal rod to ensure its stability during the cleaning process and prevent shaking or displacement. The spindle removal rod fastening mechanism 42 is fixed in the center of the cleaning chamber 2 to ensure that the water flow of the flushing mechanism 5 on both sides evenly covers the surface of the rod and avoids cleaning dead corners. At the same time, the inner tube 43 extends to the middle of the two sets of fastening mechanisms 42 and can extend to the inner end of the spindle removal rod to clean its interior. It works in conjunction with the flushing mechanism 5 to perform synchronous cleaning inside and outside, thereby improving the cleaning effect.

[0043] Please see Figure 2 Both sets of connecting base plates 41 have a connecting notch 411 at their bottom center. The top surface of each connecting notch 411 has an inner groove 412 at its center. The two sets of connecting base plates 41 are connected to each other by a drive shaft 413. The front and rear ends of the drive shaft 413 extend into the two inner grooves 412 and are fixedly connected to a gear 414. Rotation of the drive shaft 413 can drive the two gears 414 to rotate. A gear 415 is fixedly connected to the outer center of the drive shaft 413. A gear 416 is connected to the top of the gear 415. The gear 415 and the gear 416 mesh. A drive motor 417 is connected to the rear center of the gear 416. The front end of the drive shaft of the drive motor 417 is fixedly connected to the rear center of the gear 416, which can drive the gear 416 to rotate.

[0044] Specifically, the drive motor 417 drives the gear 416 to rotate, and the gear 415 and the transmission shaft 413 synchronously drive the two sets of gears 414 to rotate, which facilitates the synchronous drive of the fastening mechanism 42. At the same time, the gear 414 is embedded in the inner groove 412. The compact layout of the gears 415 and 416 can effectively reduce external interference, reduce the risk of wear, and extend the service life.

[0045] Please see Figure 3Both sets of fastening mechanisms 42 have identical components. The fastening mechanism 42 includes a turntable 421, a toothed gear 422, a central hole 423, an inner wheel 424, and a first linkage mechanism 425. The top of the turntable 421 extends into the connecting notch 411. A set of annular grooves is provided at the front and rear of the turntable 421 near the outer end, and the turntable 421 is connected to the connecting notch 411 through the annular grooves, allowing it to rotate within the connecting notch 411. The outer side of the turntable 421 is provided with at least two sets of toothed gears 422 at equal intervals. The toothed gears 422 mesh with the first gear 414. The rotation of the first gear 414 can drive the turntable 421 to rotate back and forth within the connecting notch 411 through the toothed gears 422. A central hole 423 is provided in the middle of both sets of turntables 421. An inner wheel 424 is installed in the inner end of the turntable 421, allowing the inner wheel 424 to rotate within the turntable 421. A first linkage mechanism 425 is provided at each of the four ends of the inner wheel 424.

[0046] Specifically, the top of the turntable 421 is located inside the connecting notch 411, and the protruding tooth 422 meshes with the gear 414, which can drive the two sets of turntables 421 to rotate synchronously, realizing efficient power transmission. The rotation of the inner wheel 424 can drive the linkage mechanism 425 to clamp and fix the bar in the central hole 423.

[0047] Please see Figures 2-4 An inner groove 4241 is provided at the upper left end of the turntable 421 near the inner side of the inner wheel 424. A drive motor 4242 is installed at the front end of the turntable 421 corresponding to the inner groove 4241. The drive motor 4242 is covered with a motor cover to waterproof it. The rear end of the drive shaft of the drive motor 4242 extends through the inner groove 4241 and is fixedly connected to a gear 4243. A rack 4244 is fixedly connected at the inner side of the inner wheel 424 corresponding to the inner groove 4241. The rack 4244 meshes with the gear 4243. The drive motor 4242 can drive the gear 4243 to rotate, and drive the inner wheel 424 to rotate through the rack 4244.

[0048] Specifically, the drive motor 4242 drives the rack 4244 through the gear 4243, thereby precisely controlling the rotation of the inner wheel 424. The linkage mechanism 425 clamps and fixes the spindle rod. The power transmission is direct and efficient, and the inner wheel 424 responds quickly, which can reduce the waiting time of the cleaning process and is suitable for high-frequency operation.

[0049] Please see Figure 5The linkage mechanism 425 includes a through groove 4251, a clamping block 4252, a central shaft 4253, a connecting arm 4254, and a central groove 4255. A set of through grooves 4251 is provided at each of the four ends of the inner wheel 424, corresponding to the inner end of the turntable 421, and communicates with the central hole 423. A set of clamping blocks 4252 is slidably connected within each through groove 4251. Each clamping block 4252 is connected to the inner side of the inner wheel 424 via a set of connecting arms 4254. A set of central shafts 4253 are fixedly connected to the middle of the through groove 4251. A set of central grooves 4255 corresponding to the central shafts 4253 are opened at the inner end of the connecting arm 4254. The central shafts 4253 can move in the central grooves 4255. When the inner wheel 424 rotates, it can move around the central shafts 4253 through the connecting arm 4254 to pull or push the clamping block 4252, so that it can move in the through groove 4251, which is convenient for clamping and fixing or releasing the spindle removal rod.

[0050] Specifically, the four sets of linkage mechanisms 425 are evenly distributed to form four-point synchronous clamping, ensuring that the force on the unloading rod is uniform and avoiding deformation or damage caused by stress concentration at a single point. The drive motor 4242 drives the inner wheel 424 to rotate through the rack 4244, and drives the clamping block 4252 to move radially in sync through the four sets of connecting arms 4254, which can realize rapid concentric clamping or loosening.

[0051] Please see Figures 6-7 Both sets of flushing mechanisms 5 have identical components. The flushing mechanism 5 includes a movable groove 51, an expansion groove 52, a third drive motor 53, a second linkage mechanism 54, an inner plate 55, a nozzle 56, and a water pipe 57. A set of movable grooves 51 is provided at the front end of the left and right sides of the cleaning chamber 2. An expansion groove 52 is provided at the position of the front movable groove 51 away from the cleaning chamber 2. A set of third drive motors 53 is installed in each expansion groove 52. The front end of the drive shaft of the third drive motor 53 is connected to the inner plate through the second linkage mechanism 54. 55. The inner panel 55 is attached to the inner side of the cleaning chamber 2. At least two sets of nozzles 56 are fixedly connected to the side of the inner panel 55 away from the movable slot 51. The nozzles 56 are arranged in two rows, and the two rows of nozzles 56 are staggered to expand the coverage of the nozzles 56 and improve the cleaning effect. A set of water supply pipes 57 is connected to the middle of the other side of the inner panel 55. One end of the water supply pipes 57 is connected to the nozzles 56, and the other end extends through to the outer end of the cleaning body 1, which can be connected to an external water source to provide cleaning water for the nozzles 56.

[0052] Specifically, the drive motor 3 53 drives the inner plate 55 to reciprocate within the cleaning chamber 2 through the linkage mechanism 2 54, causing the water flow coverage area to change dynamically and form a cross water curtain coverage, ensuring that there are no dead corners on the surface of the spindle removal rod.

[0053] Please see Figure 6-Figure 8The second linkage mechanism 54 includes a first linkage arm 541, a second linkage arm 542, a third linkage arm 543, a recycling trough 544, a spring 545, and a fourth linkage arm 546. A set of second linkage arms 542 is hinged to one end of the first linkage arm 541 near the third drive motor 53. The other end of the second linkage arm 542 is fixedly connected to the front end of the drive shaft of the third drive motor 53. The drive shaft of the third drive motor 53 can drive the second linkage arm 542 to rotate. A set of third linkage arms 543 is connected inside the rear movable groove 51. The length of the first linkage arm 541 is twice that of the third linkage arm 543. The middle end of the first linkage arm 541 is rotatably connected to the middle end of the front movable groove 51. The third linkage arm 543 is away from the inner plate 55. One end is rotatably connected to the middle of the rear movable groove 51. A set of recycling grooves 544 are opened at the middle of the side of the linkage arm 1 541 and linkage arm 3 543 away from the drive motor 3 53. A set of springs 545 are connected in the recycling grooves 544. The other end of the springs 545 is connected to a set of linkage arms 4 546. The other ends of the two sets of linkage arms 4 546 are connected to the front and rear ends of the inner plate 55. When the inner plate 55 moves up and down along the inner side of the cleaning chamber 2, the linkage arms 4 546 can stretch the springs 545. When the inner plate 55 moves towards the middle along the inner side of the cleaning chamber 2, the springs 545 can pull the linkage arms 4 546 into the recycling grooves 544, so that the inner plate 55 can always fit against the inner side of the cleaning chamber 2.

[0054] Specifically, the drive motor 3 53 drives the linkage arm 1 541 to reciprocate around the middle end through the linkage arm 2 542, thereby driving the inner plate 55 to reciprocate inside the cleaning chamber 2. The linkage arm 3 543 can limit the rear end of the inner plate 55, improve the stability of the inner plate 55 when it moves, change the flushing and cleaning angle of the spindle rod, improve cleaning efficiency, and avoid dead corners.

[0055] This invention provides a cleaning device for the spindle handle of a cotton harvester. The device comprises two sets of connecting base plates 41 positioned at the front and rear of the top surface of the cleaning chamber 2, connected by a drive shaft 413. A drive motor 417 rotates the drive shaft 413, which, along with a gear 414, synchronously drives two sets of fastening mechanisms 42. This eliminates the eccentric torque caused by traditional single-sided driving, achieving precise synchronous movement of the two sets of fastening mechanisms 42 and preventing interference between them, which would affect the clamping and movement of the spindle handle. The fastening mechanism 42, located at the bottom of the connecting base plates 41, includes a turntable 421, protruding teeth 422, a central hole 423, an inner wheel 424, and a linkage mechanism 425. The turntable 421 is connected to the gear 414 via the protruding teeth 422. The meshing of the four components allows the spindle removal rod to reciprocate at the bottom of the connecting base plate 41, optimizing the fixed cleaning method of traditional cleaning devices. This allows for changes in the cleaning angle of the spindle removal rod, expanding the cleaning surface, increasing flexibility, and significantly improving the cleaning effect. Two sets of flushing mechanisms 5, located at the left and right ends of the cleaning chamber 2, are used. Each flushing mechanism 5 includes a movable groove 51, an expansion groove 52, a third drive motor 53, a second linkage mechanism 54, an inner plate 55, a nozzle 56, and a water pipe 57. These components work together to drive the inner plate 55 and the nozzle 56 to reciprocate up and down on the left and right sides of the cleaning chamber 2, changing the cleaning and flushing direction of the spindle removal rod and achieving dynamic coverage cleaning. Compared to traditional fixed cleaning methods, this mechanism effectively improves the flexibility of cleaning, forming a cross-water curtain coverage, ensuring no cleaning dead corners on the surface of the spindle removal rod, and improving cleaning efficiency.
