Description

Technical Field

[0001] This utility model relates to the technical field of sugarcane harvesting devices, specifically a rotary single sugarcane harvesting device. Background Technology

[0002] Sugarcane (scientific name: Saccharumofficinarum Sugarcane (Saccharum spp.) is a perennial, tall, solid herbaceous plant. It has a robust and well-developed rhizome. The culms reach a height of 3-6 meters. Sugarcane thrives in fertile soil, abundant sunshine, and areas with significant temperature differences between winter and summer. A temperate and tropical crop, sugarcane is the raw material for sugar production and can also be used to extract ethanol as an energy substitute. It is an important sugar crop in my country and a major source of sugar. The green development and sustainable high-yield cultivation of sugarcane are crucial for national sugar security. Sugarcane is the most widely planted economic crop in Guangxi. According to data from the National Bureau of Statistics in 2018, Guangxi's sugarcane planting area was 886,400 hectares (approximately 1.3 million mu), accounting for 63.05% of the national planting area; sugarcane output was 72.9276 million tons, accounting for 67.46% of the national total; and sugar production was 5.9 million tons, accounting for 67.23% of the national total.

[0003] Sugarcane cultivation in Guangxi is predominantly located in hilly areas with complex terrain. The need to retain ratoons for at least three years and other planting requirements have hindered the development of mechanized sugarcane harvesting. Traditionally, sugarcane harvesting relies heavily on manual labor, which is physically demanding, inefficient, and arduous. The sugar industry and sugarcane farmers urgently need mechanized harvesting methods. In recent years, with the significant increase in labor costs, manual sugarcane harvesting has been increasingly abandoned by sugarcane growers, replaced by sugarcane harvesters. On relatively flat land, sugarcane harvesters are significantly more efficient than manual harvesting, and also offer cost advantages. Existing sugarcane harvesters mainly consist of imported and domestically produced combine harvesters, primarily including stalk-cutting and whole-stalk harvesters. Both types have their own limitations.

[0004] Cutting combine harvesters have mature applications abroad and are highly reliable. However, these large sugarcane harvesters are bulky, heavy, complex in structure, and have large tires with wide wheelbases. In my country's scattered, small-plot planting conditions, turning around at the edge of the field is extremely inconvenient. While they achieve a certain level of efficiency, because they cut sugarcane into small sections of about 40 centimeters, the cut sugarcane has a short shelf life and must be immediately transported to the sugar mill for processing. Furthermore, a transport vehicle is needed to receive the sugarcane during operation, and when two vehicles are working together, the sugarcane roots are severely damaged or crushed. This makes them unsuitable for sugarcane fields in most mountainous and hilly areas of my country, as well as for the need to preserve ratooned sugarcane after harvest. Moreover, the production cost of these machines is very high abroad, resulting in extremely expensive purchase and operating costs. The technology of whole-stalk combine harvesters is not mature enough, and their applicability and reliability are poor. They are difficult to work smoothly in sugarcane fields with lodging or dense sugarcane growth. Because they harvest in a straight line along the entire ridge, they are prone to blockage of the sugarcane conveying channel when encountering lodging or dense sugarcane growth, and they are also prone to damage to the leaf stripping components. Their continuous working time is short.

[0005] In order to realize the whole-stalk combined harvesting of sugarcane as soon as possible, the single-stalk sugarcane harvesting method is also an important research direction. Published literature has also reported single-stalk sugarcane harvesting devices, such as: Chinese Patent: A single-stalk harvesting sugarcane harvesting device, application number: 202022824954.8, application date: 2020.12.01, abstract: A single-stalk harvesting sugarcane harvesting device includes a frame, a controller and a guide rail. The controller and the guide rail are both installed on the frame. A locking rod and an active sliding rod are installed on the guide rail. The active sliding rod is connected to the locking rod through a mounting lug and a pull spring. A fixed clamp is installed at the front end of the positioning rod, and a movable clamp is installed on the fixed clamp via a hinge shaft. One side of the movable clamp is connected to the front end of the drive slide rod via an elastic mechanism. A blade holder is also hinged to the hinge shaft, and the blade holder is connected to the front end of the drive slide rod via a transmission mechanism. A cutting blade is installed on the blade holder, which is used to cut the sugarcane clamped by the movable and fixed clamps. A reverse clamping mechanism is fixedly installed on the drive slide rod, and the reverse clamping mechanism is connected to the other side of the movable clamp. The frame is equipped with a positioning mechanism, a cutting limit switch, and a power mechanism. The controller is connected to the cutting limit switch and the power mechanism via wires. This device cuts sugarcane stalk by stalk, ensuring the reliability of the whole-stalk combine harvester.

[0006] Applied research has revealed that the aforementioned single-stalk harvesting sugarcane harvester requires precise alignment of the clamps with the sugarcane for cutting, necessitating accurate clamp control and making automatic clamp alignment difficult. Therefore, it is necessary to design a single-stalk sugarcane harvesting device that facilitates automatic sugarcane harvesting. Summary of the Invention

[0007] The purpose of this invention is to provide a rotary single sugarcane harvesting device. This rotary single sugarcane harvesting device has an ingenious structure and is easy to realize automatic sugarcane harvesting.

[0008] To achieve the objective of this utility model, the technical solution adopted is as follows:

[0009] A rotary single sugarcane harvesting device includes a mounting base. The mounting base has a rotating shaft rotatably mounted vertically via a shaft mounting seat and bearings. The mounting base is equipped with a power unit for driving the rotating shaft and a forward-extending longitudinal positioning sensor. The longitudinal positioning sensor can also be installed in other suitable locations, as long as it can touch the sugarcane during operation. A planetary gear system and a laterally extending rotating frame are rotatably mounted on the rotating shaft. The planetary gear system has a moving clamp eccentric wheel and a cutting eccentric wheel. The moving clamp eccentric wheel is connected to a sun gear, and the cutting eccentric wheel is connected to a gear ring. Two gears are arranged on the outer circumference of the sun gear for… The rotating solar limiting platform has a gear ring with an inner limiting platform and a recessed platform for limiting rotation. The rotating frame is equipped with a rotary brake that controls frictional contact with the rotating shaft mounting seat via the gear ring. The rotating frame is equipped with a fixed clamp, a movable clamp, a cutter, and a lateral positioning device for releasing the rotation of the gear ring. The movable clamp eccentric wheel is connected to the movable clamp via a movable clamp push rod device, and the cutter eccentric wheel is connected to the cutter via a cutter push rod device. The top of the mounting seat is hinged to the whole machine connecting seat via a mounting lug. The whole machine connecting seat is also connected to the mounting lug via a mounting lug tension spring. The mounting lug is equipped with a limiting bolt for contacting the top of the whole machine connecting seat.

[0010] A further preferred embodiment includes an electric push rod hinged between the machine connecting seat and the mounting lug for adjusting the tilt angle of the machine.

[0011] A further preferred embodiment: The rear end of the rotating frame is rotatably connected to the rotating shaft. The planetary gear system is located inside the rear end of the rotating frame. The planetary gear system includes a gear ring, a sun gear, and planet gears. The planet gear carrier of the planet gears is connected to the rotating shaft via key pins. The planet gears and the planet gear carriers are connected by an optical shaft, which supports the planet gears and enables relative rotation between the planet gears and the planet gear carriers. The sun gear is rotatably connected to the rotating shaft via a bearing. The sun gear is also connected to the rotating frame via a one-way bearing, allowing only unidirectional clockwise rotation of the sun gear relative to the rotating frame. The gear ring is also rotatably connected to the rotating shaft via a corresponding bearing. The planet gears mesh with the sun gear and the gear ring. The bottom of the gear ring is eccentrically mounted with a cutter eccentric wheel via an eccentric wheel bearing. The outer circumference of the cutter eccentric wheel is connected to a cutter push rod device for controlling the cutter's cutting action. The upper part of the sun gear is eccentrically mounted with a movable clamp eccentric wheel via an eccentric wheel bearing. The outer circumference of the movable clamp eccentric wheel is connected to a movable clamp push rod device for controlling the opening and closing of the movable clamp.

[0012] A further preferred embodiment: The rotating frame includes an upper support and a lower support, which are connected as a whole. Fixed clamps are respectively provided at the front ends of the upper and lower supports. The rear end of the upper support is rotatably connected to the rotating shaft via an upper support rotating seat, and the rear end of the lower support is rotatably connected to the rotating shaft via a lower support rotating seat. A rotary brake is mounted on the upper support rotating seat via a connecting arm. The rotary brake includes a limiting wedge and a rotating mounting seat. The rotating mounting seat is fixedly connected to the connecting arm. A brake rotating shaft is fixedly connected to the bottom of the limiting wedge. The brake rotating shaft is rotatably mounted in the rotating mounting seat via a bearing. A limiting nut is installed at the lower end of the brake rotating shaft. A brake reset torsion spring is installed on the brake rotating shaft. A brake lever for friction braking between the limiting wedge and the rotating shaft mounting seat is also fixedly connected to the bottom of the limiting wedge. A pulley for contacting the gear ring is rotatably mounted at the lower end of the brake lever.

[0013] A further preferred embodiment: The movable clamp push rod device includes a linear bearing housing located on a rotating frame behind the movable clamp. A linear bearing is installed inside the linear bearing housing, and a movable clamp push rod passes through the linear bearing. One end of the movable clamp push rod is connected to the movable clamp via a movable clamp push connecting rod. The movable clamp is hinged to the rotating frame via a hinge shaft. The other end of the movable clamp push rod is hinged to the movable clamp eccentric wheel via a movable clamp release snap seat. A limiting seat for actuating the movable clamp release snap seat is installed at the bottom of the mounting base. The rotation of the movable clamp eccentric wheel drives the movable clamp push rod to move along the linear shaft. The reciprocating motion within the bearing seat enables the movable clamp to open and close in coordination with the fixed clamp to clamp or release the sugarcane. At this time, the movable clamp push rod is linearly connected to the movable clamp release stop. When sugarcane is clamped, the movable clamp cannot reach the upper stop point, and the linear connection restricts the movable clamp eccentric wheel from continuing to rotate. When the movable clamp release stop hits the limit seat, the movable clamp push rod and the movable clamp release stop deflect, and the movable clamp eccentric wheel can continue to rotate. After reaching the highest point, it pulls back the release stop, causing the movable clamp push rod to retract within the linear bearing seat, the movable clamp opens, and the clamped sugarcane is released.

[0014] A further preferred embodiment: The movable clamp release and impact-opening seat includes a hinged rod, one end of which is hinged to the movable clamp push rod. A baffle for limiting the movable clamp push rod is provided on the clockwise rotation side of the hinged rod. The other end of the hinged rod is hinged to the movable clamp eccentric wheel. The counterclockwise rotation side of the hinged rod is connected to the movable clamp eccentric wheel through a tension spring and a tension spring mounting lug. An upwardly extending impact-opening lever is connected to the hinged end of the hinged rod and the movable clamp push rod. A universal ball is installed on the impact-opening lever for touching the limiting seat. When the rotating frame continues to rotate clockwise, after the universal ball touches the limiting seat, the movable clamp release and impact-opening seat and the movable clamp push rod deflect. The movable clamp eccentric wheel can continue to rotate, driving the movable clamp push rod to retract in the linear bearing seat, the movable clamp opens, and the clamped sugarcane is released.

[0015] A further preferred embodiment: The cutter push rod device includes a linear bearing housing, which is located on a rotating frame behind the cutter. A linear bearing is installed inside the linear bearing housing, and a cutter push rod passes through the linear bearing. One end of the cutter push rod is connected to the cutter via a cutter pusher connecting rod. The cutter is hinged to the rotating frame via a hinge shaft. The other end of the cutter push rod is hinged to a cutter eccentric wheel. The rotation of the cutter eccentric wheel drives the cutter push rod to extend and retract within the linear bearing housing, thereby realizing the opening and closing of the cutter to cut sugarcane.

[0016] A further preferred embodiment: The power unit includes a motor, with a reducer connected to the motor shaft. The reducer's output shaft is connected to the shaft via a coupling. The reducer and motor can be fixedly mounted on a mounting base. The power output from the motor is transmitted to the shaft after passing through the reducer, driving the shaft to rotate. The longitudinal positioning sensor includes a longitudinal positioning rod and a proximity switch. The longitudinal positioning rod extends forward through a sliding sleeve and is slidably mounted on the mounting base. A compression return spring is installed on the longitudinal positioning rod. The proximity switch is fixedly mounted on the mounting base and is triggered by the sliding of the longitudinal positioning rod to start the motor. When the device moves forward, the longitudinal positioning rod first touches the sugarcane, is squeezed and retracted by the sugarcane, and then triggers the proximity switch. The proximity switch transmits a signal to the controller, which controls the motor to work according to the set program. When the sugarcane is cut and clamped away, the longitudinal positioning rod returns to its original position under the action of the compression return spring.

[0017] A further preferred embodiment: The lateral positioning device includes a lateral positioning clamp and a positioning clamp push rod. The lateral positioning clamp is hinged to the rotating frame via a hinge shaft. A linear bearing seat is provided on the rotating frame behind the lateral positioning clamp. A linear bearing is installed inside the linear bearing seat, and a lateral positioning clamp push rod passes through the linear bearing. One end of the lateral positioning clamp push rod is connected to the lateral positioning clamp via the positioning clamp push rod. The rotation of the lateral positioning clamp pulls the positioning clamp push rod to slide within the linear bearing seat. The other end of the lateral positioning clamp push rod is connected to a limit wheel seat. A limit wheel for limiting the rotation of the gear ring is installed on the limit wheel seat. A lateral positioning return spring is installed on the lateral positioning clamp push rod between the limit wheel seat and the linear bearing seat. When the rotating frame rotates, the lateral positioning clamp first touches the sugarcane, causing the lateral positioning clamp to rotate under pressure. This pulls the positioning clamp push rod, causing the limit wheel seat and the limit wheel to extend forward, creating space for the gear ring to rotate, and compressing the lateral positioning return spring.

[0018] A further preferred embodiment includes a positioning proximity switch installed at the bottom of the mounting base, which triggers the motor to shut off when the rotating frame rotates to the desired position. When the rotating frame reaches the starting position, the positioning proximity switch is triggered, transmitting a signal to the controller, which then shuts off the motor.

[0019] This rotary single-stalk sugarcane harvester features an ingenious structure. A planetary gear system and a laterally extending rotating frame are mounted on a rotating shaft. The planetary gear system houses a movable clamp eccentric wheel for opening and closing the clamp and a cutter eccentric wheel for driving the cutter. The movable clamp eccentric wheel is connected to a sun gear, and the cutter eccentric wheel is connected to a gear ring. Two sun limit platforms are located on the outer circumference of the sun gear. The gear ring has an inner limit platform and a recessed platform. The rotating frame includes a fixed clamp, a movable clamp, a cutter, and a lateral positioning device. A rotary brake, controlled by the gear ring, is mounted on the rotating frame and rubs against the rotating shaft mounting base. The top of the mounting base is hinged to a machine connection base via a lifting lug. The lifting lugs are connected to the lifting lugs via a spring. The eccentric wheel of the movable clamp is connected to the movable clamp via a movable clamp push rod device. The rotation of the eccentric wheel controls the opening and closing of the movable clamp and its engagement with the fixed clamp to clamp the sugarcane. The eccentric wheel of the cutter is connected to the cutter via a cutter push rod device. The rotation of the eccentric wheel controls the cutter to cut the sugarcane via the cutter push rod device. After the rotating frame rotates to the appropriate position, it touches the movable clamp push rod device, thereby releasing the sugarcane. The rotating frame continues to rotate to the initial position and then stops working, waiting for the longitudinal positioning sensor to be triggered again. This achieves the purpose of rotating to touch the sugarcane, gripping the sugarcane, cutting the sugarcane, and rotating to transport the sugarcane, which is conducive to realizing automatic clamping of the sugarcane by the clamp before cutting.

The planetary gear system includes a gear ring 10, a sun gear 9, and planet gears 42. The planet gear carrier 43 of the planet gear 42 is connected to the rotating shaft 13 via a key pin. The planet gears 42 and the planet gear carrier 43 are connected by an optical axis, which supports the planet gears 42 and enables the planet gears 42 and the planet gear carrier 43 to rotate relative to each other. The sun gear 9 is rotatably connected to the rotating shaft 13 via a bearing. The gear ring 10 is also rotatably connected to the rotating shaft 13 via a corresponding bearing. The planet gears 42 mesh with the sun gear 9 and the gear ring 10. The bottom of the gear ring 10 is eccentrically mounted with a cutter eccentric wheel 11 via an eccentric wheel bearing.

A limiting seat 40 for actuating the movable clamp release snap-opening seat 36 is installed at the bottom of the mounting base 4. The rotation of the movable clamp eccentric wheel 8 drives the movable clamp push rod 29 to move on the linear bearing. The moving clamp 24 opens and closes in conjunction with the fixed clamp 21 to clamp or release the sugarcane 59. At this time, the moving clamp push rod 29 is linearly connected to the moving clamp release stop 36. When the sugarcane is clamped, the moving clamp cannot reach the upper stop point, and the linear connection restricts the moving clamp eccentric wheel 8 from continuing to rotate. When the moving clamp release stop 36 hits the limit seat 40, the moving clamp push rod 29 and the moving clamp release stop 36 deflect, and the moving clamp eccentric wheel 8 can continue to rotate. After reaching the highest point, it pulls back the release stop 36, causing the moving clamp push rod 29 to retract in the linear bearing seat 17, the moving clamp 24 opens, and the clamped sugarcane 59 is released.

The push lever 57 is equipped with a universal ball bearing 58 for touching the limit seat 40. When the rotating frame 14 continues to rotate clockwise, after the universal ball bearing 58 touches the limit seat 40, the movable clamp release push seat 36 and the movable clamp push rod 29 deflect. The movable clamp eccentric wheel 8 can continue to rotate. After reaching the highest point, it pulls back the release push seat 36, causing the movable clamp push rod 29 to retract in the linear bearing seat 17. The movable clamp 24 opens, and the clamped sugarcane 59 is released.

[0037] The cutter push rod device includes a linear bearing seat 17, which is located on a rotating frame 14 behind the cutter 20. A linear bearing is installed inside the linear bearing seat 17, and a cutter push rod 16 passes through the linear bearing.

The other end of the cutter push rod 16 is hinged to a cutter eccentric wheel 11. The rotation of the cutter eccentric wheel 11 drives the cutter push rod 16 to extend and retract within the linear bearing seat 17, thereby realizing the opening and closing of the cutter 20 to cut sugarcane.

[0038] The power unit includes a motor 1, with a reducer 2 connected to the motor 1's shaft. The output shaft of the reducer 2 is connected to the shaft 13 via a coupling. The reducer 2 and motor 1 can be fixedly mounted on the mounting base 4. The power output from the motor is transmitted to the shaft after passing through the reducer, driving the shaft to rotate. The longitudinal positioning sensing device includes a longitudinal positioning rod 27 and a proximity switch 30. The longitudinal positioning rod 27 extends forward through a sliding sleeve and is slidably mounted on the mounting base 4. A compression return spring 28 is installed on the longitudinal positioning rod 27.

When the device moves forward, the longitudinal positioning rod 27 first touches the sugarcane 59 and is squeezed back by the sugarcane 59. Then, the longitudinal positioning rod 27 triggers the proximity switch 30, which transmits a signal to the controller. The controller controls the motor 1 to work according to the set program. When the sugarcane 59 is cut off and clamped away, the longitudinal positioning rod 27 returns to its original position under the action of the compression return spring 28.

The lateral positioning clamp 22 is hinged to the rotating frame 14 via a hinge shaft 19. The rotating frame 14 behind the lateral positioning clamp 22 is provided with a linear bearing seat 17. A linear bearing is installed in the linear bearing seat 17, and a lateral positioning clamp push rod 26 passes through the linear bearing. One end of the lateral positioning clamp push rod 26 is connected to the lateral positioning clamp 22 via the positioning clamp push rod 23.

A lateral positioning return spring 44 is installed on the lateral positioning clamp push rod 26 between the limit wheel seat 45 and the linear bearing seat 17. When the rotating frame 14 rotates, the transverse positioning clamp 22 first touches the sugarcane. The transverse positioning clamp 22 is squeezed and rotated, which pulls the positioning clamp to push the connecting rod 23 to drive the limit wheel seat 45 and the limit wheel 46 to extend forward, making room for the gear ring 10 to rotate. The transverse positioning return spring 44 is compressed.

[0040] The mounting base 4 is equipped with a positioning proximity switch 41 that triggers the shutdown of motor 1 when the rotating frame 14 rotates to the desired position. When the rotating frame 14 rotates to the starting position, the positioning proximity switch 41 is triggered, and the positioning proximity switch 41 transmits a signal to the controller, which then shuts down motor 1.

[0041] The working principle of this rotary single sugarcane harvester is as follows: the whole machine connecting seat 32 is fixedly connected to the harvester, and the harvester carries the harvesting device. Before operation, the tilt angle of the harvesting device is adjusted by the electric push rod 31, and the extension length of the limit bolt 34 is adjusted to limit the forward swing position of the mounting lug 35; the rotating frame 14 is in the initial position, the moving clamp 24 is open, the inner retaining limit platform 15 of the gear ring is limited by the limit wheel 46, and one of the sun limit platforms 37 on the outer circumference of the sun wheel 9 is stuck by the inner retaining limit platform 15 of the gear ring. The gear ring 10 and the sun wheel 9 cannot rotate clockwise, the pulley 54 is lifted by the outer circumference of the gear ring 10, and the limit wedge block 47 of the rotary brake 5 does not contact the rotating shaft mounting seat 3 and is in a non-braking state. When the harvester is moving, the longitudinal positioning rod 27 touches the sugarcane 59 and is pressed back. The compression return spring 28 is compressed, and the longitudinal positioning rod 27 also triggers the proximity switch 30, stopping the harvester. The control center controls the drive motor 1 to rotate clockwise. The power output of the motor 1 is transmitted to the rotating shaft 13 through the coupling after passing through the reducer 2, and drives the rotating shaft 13 to rotate. The planetary gear carrier 43 of the planetary gear 42 is connected to the rotating shaft 13 through a key pin. The planetary gear 42 and the planetary gear carrier 43 are connected by an optical shaft, which supports the planetary gear 42 and enables the planetary gear 42 and the planetary gear carrier 43 to rotate relative to each other. The sun gear 9 is rotatably connected to the rotating shaft 13 through a bearing, and the gear ring 10 is also rotatably connected to the rotating shaft 13 through a corresponding bearing. The planetary gear 42 meshes with the sun gear 9 and the gear ring 10. Since the sun gear 9 and the gear ring 10 are restricted from rotating clockwise, the rotating shaft 13 drives the rotating frame 14 to rotate clockwise as a whole.When the sugarcane 59 rotates to the point where it touches and presses the transverse positioning clamp 22, the transverse positioning clamp 22 flips around the hinge shaft 19 as a fulcrum and pulls the positioning clamp to push the connecting rod 23, causing the limiting wheel seat 45 and the limiting wheel 46 to extend forward, making room for the rotation of the gear ring 10. The gear ring inner retaining limiting platform 15 is not restricted by the limiting wheel 46, so the gear ring 10 can rotate. The sun limiting platform 37 is not restricted by the gear ring inner retaining limiting platform 15, so the sun wheel 9 can also rotate. The driving force of the rotating shaft 13 drives the gear ring 10 and the sun wheel 9 to rotate through the planetary gear 42. After the gear ring 10 and the sun wheel 9 rotate, the pulley 54 falls into the outer ring recess between the recessed platform 55 on the outer periphery of the gear ring 10 and the gear ring inner retaining limiting platform 15, providing space for inward rotation. Under the action of the brake reset torsion spring 51, the limiting wedge block 47 is driven to make frictional contact with the rotating shaft mounting seat 3 for braking, and the rotating frame 14 is not driven and stops rotating. The rotation of the sun wheel 9 drives the moving clamp eccentric wheel 8 to rotate accordingly. The hinge rod 56 drives the movable clamp push rod 29 to extend forward, causing the movable clamp 24 to rotate around the hinge shaft 19 as a fulcrum, cooperating with the fixed clamp 21 to clamp the sugarcane 59. Because the movable clamp 24 cannot reach its maximum clamping position when it is clamping the sugarcane 59, the baffle of the hinge rod 56 and the tension spring 38 keep the hinge rod 56 and the movable clamp push rod 29 in a straight-line connection position. The movable clamp eccentric wheel 8 cannot reach its top dead center, and the sun gear 9 is restricted from rotating. The rotating shaft 13... The driving force drives the gear ring 10 to rotate through the planetary gears 42, which in turn drives the cutter eccentric wheel 11 to rotate, so that the cutter push rod 16 extends forward. Through the cutter push link 18, the cutter pushes the cutter 20 to rotate and cut the sugarcane 59. After the gear ring 10 rotates more than 180 degrees, the sugarcane 59 has been cut off. The gear ring 10's inner locking limit platform 15 also lifts the pulley 54. The limit wedge block 47 of the rotary brake 5 does not contact the rotating shaft mounting seat 3 and is in a non-braking state.When the inner retaining platform 15 of the gear ring 10 rotates to the other sun retaining platform 37 of the sun gear 9, it is restricted by the sun retaining platform 37, preventing the gear ring 10 from rotating. Since neither the gear ring 10 nor the sun gear 9 can rotate, the power output by the motor 1 drives the rotating frame 14 to continue rotating clockwise through the rotating shaft 13. When the rotation reaches the point where the universal ball 58 on the impact lever 57 touches the retaining seat 40, the sugarcane 59 is also clamped and transported into position, giving the universal ball 58 a clockwise force, causing the impact lever 57 to deflect, and the moving clamp eccentric wheel 8 can continue to rotate. After reaching the highest point, the sun gear 9 can drive the moving clamp eccentric wheel 8 to continue rotating, pulling back the impact seat 36 through the hinge rod 56, causing the moving clamp push rod 29 to retract backward, the moving clamp 24 to open, and the sugarcane 59 falls off and is transported by other mechanisms of the harvester for leaf removal. Without the pressure of sugarcane 59, under the action of the transverse positioning and return spring 44, the positioning clamp pushes the connecting rod 23, the limit wheel seat 45, and the limit wheel 46 to retract and reset. At this time, the universal ball 58 on the lever 57 is still blocked by the limit seat 40, the swing frame 14 has a large rotational resistance and cannot rotate, while the gear ring 10 and the sun gear 9 have a small rotational resistance and can rotate. When the gear ring inner retaining limit platform 15 of the gear ring 10 rotates to the limit wheel 46, it is limited by the limit wheel 46 and cannot continue to rotate. The moving clamp 24 opens, and the sun limit platform 37 of the sun gear 9 gets stuck when it rotates to the gear ring inner retaining limit platform 15. The cutter opens; the gear ring 10 and the sun gear 9 cannot continue to rotate clockwise, and the pulley 54 is pushed by the outer circumference of the gear ring 10. Initially, the limiting wedge 47 is not in contact with the rotating shaft mounting seat 3 and is in a non-braking state. The limiting seat 40 is an elastic element, and its elastic resistance can push the hinge rod 56 and the moving clamp push rod 29 to deflect when pressed. However, when the rotating shaft 13 drives the rotating frame 14 to rotate with a large torque, the universal ball bearing 58 can press down the limiting seat 40 to continue rotating clockwise. When the positioning proximity switch 41 is triggered, the controller controls the motor 1 to stop working. At this time, it is in the initial position, waiting for the proximity switch 30 to send a signal again, and then repeats the above operation.

Any changes, modifications, additions, or substitutions made by those skilled in the art within the scope of this application should fall within the protection scope of this application.
