Description

[0001] This application relates to the field of agricultural machinery technology, and in particular to an electrically driven, independently controlled cotton harvester head. Background Technology

[0002] In the field of agricultural machinery, the development of cotton harvesters has played a crucial role in the efficient harvesting of cotton. With the advancement of agricultural modernization, cotton harvesters are constantly being upgraded, and their performance and efficiency are gradually improving. As the core actuator of the cotton harvester, the harvester head directly affects the quality and efficiency of cotton harvesting. An efficient and stable harvester head can greatly increase the speed of cotton harvesting, reduce labor costs, and promote the large-scale development of the cotton industry.

[0003] Most existing cotton harvester heads utilize hydraulic drives combined with complex mechanical transmission structures in their power systems. Hydraulic drive is a common power transmission method that can provide significant power output. The complex mechanical transmission structure is used to transmit power to the various moving parts of the cotton harvester head, enabling actions such as cotton harvesting and unharvesting. The entire harvester head is typically driven by a single power source, distributing power to different working parts through a series of gears, chains, and other transmission components.

[0004] However, this existing technology has significant drawbacks. Its control precision is insufficient, making it difficult to independently and precisely control the speed and direction of each moving part inside the cotton harvester head. Furthermore, reverse operation carries risks and cannot meet the needs of some special working conditions in actual cotton harvesting processes.

[0005] Therefore, in view of the above situation, there is an urgent need to develop an electrically driven, independently controlled cotton harvester head to overcome the shortcomings in current practical applications. Summary of the Invention

[0030] The present invention provides the following embodiments: Example 1

[0031] This application discloses an electrically driven, independently controlled cotton harvester head, referring to... Figure 1 The system includes a fixed frame 1, a drive mechanism 4, a cotton picking mechanism 2, and a cotton stripping mechanism 3. The drive mechanism 4 is mounted on the fixed frame 1, while the cotton picking mechanism 2 and the cotton stripping mechanism 3 are respectively mounted inside the fixed frame 1 and are connected to the drive mechanism 4 for transmission. This configuration allows the drive mechanism 4 to provide power to the cotton picking mechanism 2 and the cotton stripping mechanism 3, enabling them to perform cotton picking and stripping functions. Furthermore, due to the use of electric drive and independent control, compared to traditional hydraulic drive and complex mechanical transmission structures, it can improve control accuracy and meet the needs of special working conditions.

[0032] Specifically, a limiting plate 11 is horizontally installed inside the fixed frame 1, dividing the fixed frame 1 into a transmission chamber 12 and a cotton picking chamber 13. The fixed frame 1 has a cotton inlet 14 and a cotton outlet 15 at both ends. The limiting plate 11 is generally made of high-strength metal plate, such as steel plate, and its function is to separate the space, preventing interference between the transmission and cotton picking processes. The cotton inlet 14 and the cotton outlet 15 can be rectangular openings. The cotton inlet 14 facilitates the entry of cotton into the cotton picking chamber 13, and the cotton outlet 15 facilitates the output of the picked cotton. Of course, the shapes of the cotton inlet 14 and the cotton outlet 15 can also be designed as circular or other shapes according to actual needs.

[0033] The cotton picking mechanism 2 includes a first rotating shaft 21, which is located near the cotton inlet 14 and rotatably mounted on a limiting plate 11. The first rotating shaft 21 can be a solid metal shaft with a hardened surface to improve hardness and wear resistance. Two fixing plates 22 are fixedly mounted on the first rotating shaft 21, arranged parallel to each other within the cotton picking chamber 13. The fixing plates 22 can be circular metal plates, fixed to the first rotating shaft 21 by welding or bolting. Multiple connecting rods 23 are circumferentially arranged between the two fixing plates 22. The connecting rods 23 can be cylindrical metal rods, serving to connect the two fixing plates 22 and provide installation positions for the picking spindles 24. Multiple picking spindles 24 are rotatably mounted on the connecting rods 23. The picking spindles 24 can be metal rods with barbs for gripping cotton. A transmission assembly 25 is located within the connecting rods 23, and the transmission assembly 25 is connected to the picking spindles 24.

[0034] Reference Figure 2The transmission assembly 25 includes a drive cavity 251, which is formed within the connecting rod 23. Multiple spindles 24 are vertically arranged on the connecting rod 23, with one end of each spindle 24 extending into the drive cavity 251. A first spur gear 252, which can be a standard involute spur gear, is fixed to the spindle 24 via a key connection. A second spur gear 253 is rotatably connected between two adjacent spindles 24. The two adjacent first spur gears 252 mesh with the second spur gear 253, enabling synchronous rotation of the spindles 24. A first bevel gear 254 is located on the topmost spindle 24 within the drive cavity 251, also fixed to the spindle 24 via a key connection. A first transmission shaft 255 is rotatably mounted on the limiting plate 11. The first transmission shaft 255 can be a hollow metal shaft to reduce weight. A third spur gear 256 and a second bevel gear 257 are respectively provided at both ends of the first drive shaft 255. The second bevel gear 257 is located in the drive cavity 251. The first bevel gear 254 meshes with the second bevel gear 257 to transmit power from the first drive shaft 255 to the picking spindle 24. The picking spindle 24 has multiple barbed grooves, which help to better grasp cotton. A fourth spur gear 211 and a fifth spur gear 212 are provided at the top end of the first rotating shaft 21. The fourth spur gear 211 and the fifth spur gear 212 are respectively located in the transmission cavity 12. A sixth spur gear 213 is provided at the middle end of the first rotating shaft 21. The sixth spur gear 213 is located in the cotton picking cavity 13. The sixth spur gear 213 meshes with the third spur gear 256 to transmit power from the first rotating shaft 21 to the first drive shaft 255.

[0035] Reference Figure 1 The cotton removal mechanism 3 includes a second rotating shaft 31, which is located near the cotton outlet 15 and rotatably positioned between the limiting plate 11 and the bottom of the cotton picking chamber 13. The second rotating shaft 31 can be made of the same material and manufactured using the same process as the first rotating shaft 21. Multiple cotton-colliding blocks 32, which can be rubber or metal blocks, are mounted on the second rotating shaft 31. These blocks collide with the cotton-laden spindle 24, causing the cotton to detach from the spindle. A seventh spur gear 33 and an eighth spur gear 34 are mounted on the top of the second rotating shaft 31. The rotation directions of the first and second rotating shafts are opposite, allowing for better coordination between cotton picking and removal.

[0036] The drive mechanism 4 includes a first drive component 41, which is fixedly mounted on the top of the fixed frame 1. The first drive component 41 can be a motor, providing power to the entire mining head. The first drive component 41 is connected to the first rotating shaft 21 and the second rotating shaft 31 respectively through two drive components 43. A ninth spur gear 42 is fixedly mounted on the drive end of the first drive component 41.

[0037] Reference Figure 3 The drive assembly 43 includes a second drive member 431, which is fixedly mounted on the top of the fixed frame 1. The second drive member 431 can also be a motor. A second drive shaft 432 is connected to the drive end of the second drive member 431. The second drive shaft 432 can be a solid metal shaft. A tenth spur gear 433 is fitted onto the second drive shaft 432 for meshing with the ninth spur gear 42. The tenth spur gear 433 meshes with the fourth spur gear 211 or the fifth spur gear 212 to drive the first rotating shaft 21, and meshes with the seventh spur gear 33 or the eighth spur gear 34 to drive the second rotating shaft 31. Fixing pins 434 are provided on both sides of the upper part of the second drive shaft 432. A fixing groove 435 is provided inside the tenth spur gear 433 for inserting the fixing pins 434. Through the cooperation of the fixing pins 434 and the fixing groove 435, the tenth spur gear 433 and the second drive shaft 432 rotate synchronously. A blocking circular plate 436 is fixedly installed at the bottom of the second transmission shaft 432. Multiple rotating balls 437 are installed inside the blocking circular plate 436 to abut against the bottom of the tenth spur gear 433. The rotating balls 437 reduce friction between the tenth spur gear 433 and the blocking circular plate 436. A telescopic rod 438 is installed at the top of the fixed frame 1. The telescopic rod 438 can be electrically operated. A locking pin 439 is fixedly installed at the telescopic end of the telescopic rod 438. An annular groove 440 is formed at the top of the tenth spur gear 433, and the locking pin 439 is engaged within the annular groove 440. The position of the tenth spur gear 433 can be controlled by extending and retracting the telescopic rod 438, enabling different transmission combinations.

[0038] Reference Figure 1 It also includes a central controller, which is electrically connected to the first drive unit 41 and the two second drive units 431 respectively. The central controller can be a microcontroller or a PLC controller, which controls the start, stop, speed and direction of the first drive unit 41 and the two second drive units 431 through programming, so as to realize independent control of the cotton picking mechanism 2 and the cotton stripping mechanism 3.

[0039] The implementation principle of this embodiment is as follows: This embodiment adopts an independently controlled electric drive method. A central controller precisely controls the first drive component 41 and two second drive components 431 to provide power to the cotton harvesting mechanism 2 and the cotton removal mechanism 3. The cotton harvesting mechanism 2 drives the fixed plate 22 and connecting rod 23 to rotate via the first rotating shaft 21. The picking spindle 24 rotates under the action of the transmission assembly 25, using the hook groove to grab cotton. The second rotating shaft 31 of the cotton removal mechanism 3 rotates in the opposite direction to the first rotating shaft 21, and the cotton-colliding block 32 impacts the picking spindle 24 to detach the cotton. The drive assembly 43 controls the position of the tenth spur gear 433 via the telescopic rod 438 to achieve different transmission combinations to meet different working requirements. Compared with traditional cotton harvester heads, this embodiment improves control precision, enabling independent and precise control of the speed and direction of each moving part inside the cotton harvester head, and can achieve reverse operation, meeting the needs of some special working conditions in actual cotton harvesting, and improving the quality and efficiency of cotton harvesting. Example 2

[0040] The difference between this embodiment and the above embodiments is that: (Refer to...) Figure 1 In the drive mechanism 4, the first drive component 41 and the second drive component 431 use hydraulic motors instead of electric motors. Hydraulic motors have advantages such as high torque and a wide speed range. The hydraulic motors are powered by a hydraulic system, which includes components such as an oil pump, oil pipes, and control valves. The drive end of the hydraulic motor can also be connected to corresponding gears to achieve a transmission connection with the first rotating shaft 21 and the second rotating shaft 31. Furthermore, the gears in the transmission assembly 25 can be made of special materials, such as high-strength alloy steel, to improve the wear resistance and load-bearing capacity of the gears.

[0041] The implementation principle of this embodiment is as follows: a hydraulic motor is used as the driving component. Utilizing the characteristics of the hydraulic system, it can provide greater torque, making it suitable for some working conditions with high power requirements. Gears made of special materials can improve the reliability and service life of the transmission component 25, further improving the performance and stability of the cotton harvester head. Compared with traditional technology, it can also improve control accuracy and meet the needs of special working conditions.

[0042] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this application.
