Description

Technical Field

[0001] This invention relates to sugarcane harvesters, specifically to a vertical harvester suitable for defoliating and stalk-harvesting sugarcane. Background Technology

[0002] Sugarcane is a major sugar crop in my country, with over 85% of the country's sugar production coming from its stalk juice extraction. Mature sugarcane stalks are tall with numerous long leaves, and the core of whole-stalk harvesting is removing the tops and leaves. Harvesting sugarcane whole results in fewer impurities and less juice loss, making it a widely adopted harvesting method in my country, and its vitality has been increasingly evident in recent years. Whole-stalk harvesting of sugarcane generally involves cutting, stripping leaves, trimming tops, bundling, and tying, all of which are numerous and currently mostly done manually. However, relying entirely on manual labor for whole-stalk harvesting presents problems of high labor intensity, high costs, and low efficiency, becoming a bottleneck restricting the development of the sugarcane industry.

[0003] Currently, research on mechanized harvesting equipment for whole sugarcane stalks mainly focuses on two types: segmented whole-stalk harvesting and combined whole-stalk harvesting. Segmented whole-stalk harvesting involves multiple pieces of equipment to complete the harvesting process in segments. First, the sugarcane stalks with leaves are cut and laid out, then transported, leaves are stripped, and the leafless stalks are gathered. This method requires multiple locations and equipment to complete the stripping and haphazard stacking of the stalks, lacking an orderly bundling function. Therefore, it not only involves a large amount of labor during harvesting but also requires significant transport space, resulting in poor orderliness in the collection of whole sugarcane stalks. Combined whole-stalk harvesting, on the other hand, allows for one-time cutting, leaf stripping, and whole-stalk bundling on a single integrated machine. Its compact structure is being widely adopted. The above harvesting equipment primarily targets whole sugarcane stalks with leaves; no new technologies have been reported for whole sugarcane stalks without leaves.

[0004] Existing whole-stalk and leaf-removing sugarcane harvesters have the following shortcomings:

[0005] In hilly and mountainous areas with irregular land, the planting row spacing varies, while the existing whole stalk and leaf-removing sugarcane harvesters have a fixed lateral wheel spacing, making it difficult to adapt to sugarcane harvesting work with different planting row spacings. Summary of the Invention

[0006] The purpose of this invention is to overcome the above-mentioned problems and provide a vertical harvester suitable for defoliating and stalk-cultivating sugarcane. This vertical harvester can adjust its wheel track to adapt to different sugarcane planting row spacings, and has good flexibility.

[0007] The objective of this invention is achieved through the following technical solution:

[0008] A vertical harvester suitable for defoliating and stalk-cutting sugarcane includes a traveling mechanism and a harvesting operation execution device mounted on the traveling mechanism;

[0009] The walking mechanism includes a chassis, a walking component, a walking mounting frame, a walking drive mechanism, and a wheelbase adjustment drive mechanism; the walking component is rotatably connected to the walking mounting frame; the drive end of the walking drive mechanism is connected to the walking component; there are two walking mounting frames located on both sides of the chassis, and the walking mounting frames are supported on the chassis by a transverse guide structure; there are two sets of wheelbase adjustment drive mechanisms, the fixed ends of the two sets of wheelbase adjustment drive mechanisms are set on the chassis, and the drive ends of the two sets of wheelbase adjustment drive mechanisms are fixedly connected to the walking mounting frames on both sides respectively.

[0010] The working principle of the vertical harvester applicable to defoliated and stalk-whole sugarcane described above is as follows:

[0011] During operation, the sugarcane is processed by removing the leaves, so the influence of the leaves is not considered. The walking mechanism drives the walking components to rotate, allowing the harvesting equipment to move through the sugarcane field.

[0012] When encountering sugarcane fields with different row spacings, the wheel track adjustment drive mechanism drives the walking mounting frames on both sides to extend or retract, thereby obtaining the desired wheel track according to the sugarcane row spacing, adapting to different sugarcane planting row spacings, and providing good flexibility.

[0013] In a preferred embodiment of the present invention, the wheel track adjustment drive mechanism includes a wheel track adjustment electric push rod, the telescopic rod of which is connected to the walking mounting frame.

[0014] In a preferred embodiment of the invention, the traveling component is a track assembly. Of course, wheels can also be used.

[0015] In a preferred embodiment of the present invention, the harvesting operation execution device includes a support and conveying mechanism for lifting, clamping and conveying sugarcane backward, a root cutting mechanism for cutting the roots of sugarcane, a vertical stacking mechanism for stacking sugarcane, and a vertical discharge mechanism for conveying the stacked sugarcane out.

[0016] Furthermore, the supporting and conveying mechanism includes a lifting and feeding mechanism and a clamping and conveying integrated mechanism. The lifting and feeding mechanism includes two sets of lifting and feeding components arranged opposite to each other. The two sets of lifting and feeding components are funnel-shaped and tilted forward and downward.

[0017] The lifting and feeding assembly includes a lifting mounting frame, lifting and feeding fingers, a lifting transmission structure, and a lifting drive motor. The lifting mounting frame is fixedly connected to the clamping and conveying integrated mechanism. The lifting transmission structure includes a lifting transmission chain and two lifting transmission sprockets. Multiple lifting and feeding fingers are provided and positioned on the lifting transmission chain. The lifting transmission chain is positioned between the two lifting transmission sprockets, which are rotatably connected to the lifting mounting frame. One of the lifting transmission sprockets is connected to the output shaft of the lifting drive motor. Through this structure, driven by the lifting drive motor, the lifting transmission chain moves the lifting and feeding fingers from the outside in, thereby lifting the tilted sugarcane for subsequent clamping and cutting.

[0018] Furthermore, the lifting and feeding finger is rotatably connected to the lifting drive chain, and a lifting torsion spring is provided between the lifting and feeding finger and the lifting drive chain to ensure that the lifting and feeding finger is perpendicular to the tangent of the lifting drive chain; along the conveying direction, a limiting part is provided at the end of the lifting and feeding finger near the lifting drive chain to prevent the lifting and feeding finger from rotating backward.

[0019] The lifting mounting frame includes two rails, each with a conveying groove; the bottom surface of the conveying groove of the rail closer to the other lifting feeding component is provided with a limiting plate for abutting the limiting part; the rail farther from the other lifting feeding component is provided with a finger-operated counter-tilting plate covering the conveying groove. With the above structure, when the lifting and feeding finger moves in the conveying groove of the groove rail near another set of lifting and feeding components, the limiting plate presses against the limiting part of the lifting and feeding finger, thereby lifting the sugarcane. When the lifting and feeding finger moves to the conveying groove of the groove rail away from another set of lifting and feeding components, due to the lack of support from the limiting plate, after approaching the finger-falling plate, the finger-falling plate will push the lifting and feeding finger backward, causing the lifting and feeding finger to fall on the lifting transmission chain and be conveyed forward a certain distance until it passes the finger-falling plate. This can reduce the space occupied by the movement of the lifting and feeding finger, avoid interference with other structures, and help increase the opening range of the lifting and feeding mechanism, expanding the area for lifting the sugarcane. Then, under the action of the lifting torsion spring, the lifting and feeding finger returns to its normal state, ready to lift the sugarcane behind it.

[0020] Furthermore, the integrated clamping and conveying mechanism includes two sets of clamping and conveying components arranged opposite to each other, with the two sets of clamping and conveying components arranged in parallel and tilted forward and downward.

[0021] The clamping and conveying assembly includes an integrated mounting frame, an integrated closed-loop rubber cluster, an integrated transmission structure, and an integrated drive motor. The integrated mounting frame is fixedly connected to the traveling mechanism. The integrated transmission structure includes an integrated transmission chain and two integrated transmission sprockets. Multiple integrated closed-loop rubber clusters are provided and mounted on the integrated transmission chain. Each integrated closed-loop rubber cluster has a hollow structure with both ends connected, and its inner cavity forms an adaptive clamping space. The integrated transmission chain is positioned between the two integrated transmission sprockets, which are rotatably connected to the integrated mounting frame. One of the integrated transmission sprockets is connected to the output shaft of the integrated drive motor. The integrated drive motor is mounted on the integrated mounting frame. Through this structure, driven by the integrated drive motor, the integrated transmission chain moves the integrated lever from the outside inwards. Two sets of opposing integrated closed-loop rubber clusters simultaneously clamp onto the sugarcane lifted by the lifting and feeding mechanism, and then continue to straighten the sugarcane. After the root-cutting mechanism cuts the sugarcane, the two sets of opposing integrated closed-loop rubber clusters hold the sugarcane and convey it backwards until it is conveyed to the vertical stacking mechanism. Furthermore, by setting up an integrated closed-loop rubber cluster made of rubber, the sugarcane skin can be protected from being pinched and damaged. On the other hand, since the integrated closed-loop rubber cluster has an adaptive clamping space, it can adapt to the size of different sugarcanes in real time, thus stably gripping sugarcanes of different sizes, which is very ingenious.

[0022] Furthermore, another integrated drive sprocket is connected to one of the lifting drive sprockets via a drive shaft, so that they can share a single drive motor.

[0023] Furthermore, the root cutting mechanism includes a cutting wheel, a cutting drive mechanism, and a height adjustment drive mechanism. The cutting wheel is connected to the drive end of the cutting drive mechanism, and the cutting drive mechanism is mounted on the height adjustment drive mechanism.

[0024] Furthermore, the cutting drive mechanism includes a cutting drive motor, the output shaft of which is connected to the cutting wheel.

[0025] Furthermore, the height adjustment drive mechanism includes a height adjustment mounting bracket and a height electric push rod. The height adjustment mounting bracket is connected to the telescopic rod of the height electric push rod, and the cutting drive motor is mounted on the height adjustment mounting bracket.

[0026] With the above structure, when encountering different ridge heights, the height adjustment mounting bracket is driven by a height electric push rod to move vertically, thereby adjusting the height of the cutting wheel to adapt to different situations.

[0027] Furthermore, the vertical stacking mechanism includes a vertical stacking frame, a conveying stacking assembly, and a limiting stacking assembly;

[0028] The vertical stacking racks are provided in two, both of which are erected vertically, and a vertical stacking channel is provided between the two vertical stacking racks; the vertical discharge mechanism is located behind the vertical stacking channel;

[0029] The stacking and conveying assembly includes stacking fingers, a stacking and conveying transmission structure, and a stacking and conveying drive motor; the stacking and conveying transmission structure includes stacking and conveying shafts, a stacking and conveying transmission chain, and two stacking and conveying sprockets; multiple stacking fingers are provided and are mounted on the stacking and conveying transmission chain; two stacking and conveying shafts are provided and are vertically rotatably connected to one of the vertical stacking frames, and one of the stacking and conveying shafts is connected to the output shaft of the stacking and conveying drive motor; the stacking and conveying transmission chain is positioned between the two stacking and conveying sprockets; the two stacking and conveying sprockets are respectively mounted on the two stacking and conveying shafts;

[0030] The limiting stacking assembly includes a limiting stacking arm, a limiting stacking drive shaft, and a limiting stacking drive motor; the limiting stacking drive shaft is vertically rotatably connected to another vertical stacking frame, and the limiting stacking drive shaft is connected to the output shaft of the limiting stacking drive motor; one end of the limiting stacking arm is fixed to the limiting stacking drive shaft; the limiting stacking arm and the stacking finger are located at different heights;

[0031] In the stacking operation state, the other end of the limiting stacking arm extends laterally to the end of the vertical stacking channel, and the stacking finger takes the sugarcane from the supporting conveying mechanism and pushes the sugarcane to the front of the limiting stacking arm along the vertical stacking channel.

[0032] With the above structure, driven by the feeding and stacking drive motor, the feeding and stacking transmission chain drives the stacking fingers to move from the outside to the inside, thereby taking over the sugarcane on the supporting conveying mechanism and feeding it into the vertical stacking channel. Since the end of the vertical stacking channel is equipped with a limiting stacking arm, the sugarcane will be temporarily stacked at the end of the vertical stacking channel. When the sugarcane is stacked to a certain amount, the limiting stacking drive motor drives the limiting stacking arm to swing away from the end of the vertical stacking channel, and then the stacking fingers feed the sugarcane stack to the vertical discharge mechanism behind.

[0033] Furthermore, the stacking finger is rotatably connected to the stacking transmission chain, and a stacking torsion spring is provided between the stacking finger and the stacking transmission chain to ensure that the stacking finger is perpendicular to the tangent of the stacking transmission chain; along the conveying direction, a limiting post is provided at the end of the stacking finger near the stacking transmission chain to prevent the stacking finger from rotating backward.

[0034] The vertical stacking rack has a clearance hole on its side for avoiding the stacking finger; the upper and lower bottom surfaces of the clearance hole are provided with a limiting groove that cooperates with the limiting post; the position of the clearance hole corresponding to the end of the vertical stacking channel is covered with a clearance and collapse plate for pushing down the stacking finger; the position of the clearance hole corresponding to the clearance and collapse plate is not provided with the limiting groove. With the above structure, when the sugarcane-collecting finger moves and conveys sugarcane at the front-middle end of the vertical collecting channel, the limiting post of the collecting finger slides in the limiting groove, thus providing stable support for the collecting finger and preventing it from swinging backward. When the collecting finger moves to the end of the vertical collecting channel, the limiting post of the collecting finger comes out of the limiting groove and then hits the avoidance plate. The avoidance plate drives the collecting finger to swing backward, causing it to fall onto the conveying chain and be conveyed forward a certain distance until it passes the avoidance plate. Under the action of the collecting torsion spring, the collecting finger returns to its normal position. This ingenious method prevents the sugarcane from blocking the movement of the collecting finger while it is being collected.

[0035] Furthermore, the sugarcane stacking finger, the stacking transmission chain, and the stacking transmission sprocket are provided in two sets and arranged vertically to ensure that the sugarcane can be transported forward vertically.

[0036] Furthermore, the vertical discharge mechanism includes a discharge frame, discharge dials, a discharge transmission structure, and a discharge drive motor;

[0037] The discharge frame is vertically installed, and a discharge channel is provided between the discharge frame and the vertical stacking frame. The extension direction of the discharge channel is perpendicular to the extension direction of the vertical stacking channel. The discharge transmission structure includes a discharge shaft, a discharge transmission chain, and two discharge transmission sprockets. Multiple discharge fingers are provided and installed on the discharge transmission chain. The distance between two adjacent discharge fingers is greater than the width of the vertical stacking channel. Two discharge shafts are provided and vertically rotatably connected to the discharge frame, one of which is connected to the output shaft of the discharge drive motor. The discharge transmission chain is located between the two discharge transmission sprockets. The two discharge transmission sprockets are respectively installed on the two discharge shafts. With the above structure, when the sugarcane pile enters the discharge channel, the discharge drive motor drives the discharge fingers to discharge the sugarcane pile laterally.

[0038] Furthermore, the discharge finger, discharge transmission chain, and discharge transmission sprocket are provided in two sets and arranged vertically to ensure that the sugarcane can be transported forward vertically.

[0039] Compared with the prior art, the present invention has the following advantages:

[0040] The vertical harvester of the present invention can extend or retract the walking mounting frames on both sides by driving the wheel track adjustment drive mechanism, thereby obtaining the desired wheel track according to the sugarcane row spacing, so as to adapt to different sugarcane planting row spacings and have good flexibility.

[0052] To enable those skilled in the art to fully understand the technical solutions of the present invention, the present invention will be further described below in conjunction with embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0053] See Figure 1-5This embodiment of a vertical harvester suitable for defoliating and stalk-cutting sugarcane includes a walking mechanism and a harvesting operation execution device mounted on the walking mechanism. The walking mechanism includes a chassis 1, a walking component 2, a walking mounting frame 3, a walking drive mechanism, and a wheel track adjustment drive mechanism. The walking component 2 is rotatably connected to the walking mounting frame 3. The drive end of the walking drive mechanism is connected to the walking component 2. Two walking mounting frames 3 are provided and located on opposite sides of the chassis 1, supported on the chassis 1 by a transverse guide structure. Two sets of wheel track adjustment drive mechanisms are provided, with their fixed ends mounted on the chassis 1 and their drive ends fixedly connected to the walking mounting frames 3 on both sides.

[0054] See Figure 4-5 The wheel track adjustment drive mechanism includes a wheel track adjustment electric push rod 4, the telescopic rod of which is connected to the walking mounting frame 3.

[0055] Furthermore, the walking component 2 is a track assembly. Of course, it could also be wheels.

[0056] The harvesting operation device includes a support and conveying mechanism for lifting, clamping and conveying sugarcane backwards, a root cutting mechanism for cutting the roots of sugarcane, a vertical stacking mechanism for stacking sugarcane, and a vertical discharge mechanism for conveying the stacked sugarcane out.

[0057] See Figure 1-3 and Figure 6-8 The supporting and conveying mechanism includes a lifting and feeding mechanism and a clamping and conveying integrated mechanism. The lifting and feeding mechanism includes two sets of opposing lifting and feeding components, which are funnel-shaped and tilted forward and downward. Each lifting and feeding component includes a lifting mounting frame 5, lifting and feeding fingers 6, a lifting transmission structure, and a lifting drive motor. The lifting mounting frame 5 is fixedly connected to the clamping and conveying integrated mechanism. The lifting transmission structure includes a lifting transmission chain 7 and two lifting transmission sprockets. Multiple lifting and feeding fingers 6 are provided and are arranged on the lifting transmission chain 7. The lifting transmission chain 7 is arranged between two lifting transmission sprockets, and the lifting transmission sprockets are rotatably connected to the lifting mounting frame 5. Through the above structure, driven by the lifting drive motor, the lifting transmission chain 7 drives the lifting and feeding fingers 6 to move from the outside to the inside, thereby lifting the tilted sugarcane for subsequent clamping and cutting.

[0058] Furthermore, the lifting and feeding finger 6 is rotatably connected to the lifting drive chain 7. A lifting torsion spring (not shown in the figure) is provided between the lifting and feeding finger 6 and the lifting drive chain 7 to ensure that the lifting and feeding finger 6 is perpendicular to the tangential surface of the lifting drive chain 7. Along the conveying direction, a limiting part 6-1 is provided at the end of the lifting and feeding finger 6 near the lifting drive chain 7 to prevent the lifting and feeding finger 6 from rotating backward. The lifting mounting frame 5 includes two rails, each with a conveying groove. The bottom surface of the conveying groove of the rail closer to the other lifting and feeding assembly is provided with a limiting plate 8 to abut the limiting part 6-1. A finger-falling plate 9 covering the conveying groove is provided on the rail away from the other lifting and feeding assembly. With the above structure, when the lifting and feeding finger 6 moves in the conveying groove of the groove rail near another set of lifting and feeding components, the limiting plate 8 presses against the limiting part 6-1 of the lifting and feeding finger 6, thereby lifting the sugarcane; when the lifting and feeding finger 6 moves to the conveying groove away from the groove rail of another set of lifting and feeding components, due to the lack of support from the limiting plate 8, after approaching the finger-falling plate 9, the finger-falling plate 9 will push the lifting and feeding finger 6 backward, causing the lifting and feeding finger 6 to fall on the lifting transmission chain 7 and be conveyed forward a certain distance until it passes the finger-falling plate 9. This can reduce the space occupied by the movement of the lifting and feeding finger 6, avoid interference with other structures, and help increase the opening range of the lifting and feeding mechanism and expand the area for lifting the sugarcane; then, under the action of the lifting torsion spring, the lifting and feeding finger 6 returns to its normal state, ready to lift the sugarcane behind.

[0059] See Figure 1-3 and Figure 9-10The integrated clamping and conveying mechanism includes two sets of clamping and conveying components arranged opposite to each other, with the two sets of clamping and conveying components arranged in parallel and tilted forward and downward. Each clamping and conveying component includes an integrated mounting frame 10, an integrated closed-loop rubber cluster 11, an integrated transmission structure, and an integrated drive motor 12. The integrated mounting frame 10 is fixedly connected to the traveling mechanism. The integrated transmission structure includes an integrated transmission chain 13 and two integrated transmission sprockets. Multiple integrated closed-loop rubber clusters 11 are provided and arranged on the integrated transmission chain 13. The integrated closed-loop rubber cluster 11 has a hollow structure with both ends connected, and the inner cavity of the integrated closed-loop rubber cluster 11 forms an adaptive clamping space. The integrated transmission chain 13 is arranged between two integrated transmission sprockets, and the integrated transmission sprockets are rotatably connected to the integrated mounting frame 10. One of the integrated transmission sprockets is connected to the output shaft of the integrated drive motor 12. The integrated drive motor 12 is arranged on the integrated mounting frame 10. With the above structure, driven by the integrated drive motor 12, the integrated transmission chain 13 drives the integrated shift finger to move from the outside to the inside. Two sets of opposing integrated closed-loop rubber clusters 11 simultaneously clamp onto the sugarcane lifted by the lifting and feeding mechanism, and then continue to straighten the sugarcane. After the root-cutting mechanism cuts the sugarcane, the two sets of opposing integrated closed-loop rubber clusters 11 hold the sugarcane and convey it backward until it is conveyed to the vertical stacking mechanism. Furthermore, by setting the integrated closed-loop rubber clusters 11 made of rubber, on the one hand, the sugarcane skin can be protected to prevent damage; on the other hand, because the integrated closed-loop rubber clusters 11 have an adaptive clamping space, they can adaptively match the size of different sugarcane in real time, thus stably gripping sugarcane of different sizes, which is quite ingenious.

[0060] Furthermore, another integrated drive sprocket is connected to one of the lifting drive sprockets via a drive shaft, so that they can share a single drive motor.

[0061] See Figure 11 The root cutting mechanism includes a cutting wheel 14, a cutting drive mechanism, and a height adjustment drive mechanism. The cutting wheel 14 is connected to the drive end of the cutting drive mechanism, and the cutting drive mechanism is mounted on the height adjustment drive mechanism.

[0062] Furthermore, the cutting drive mechanism includes a cutting drive motor 15, the output shaft of which is connected to the cutting wheel 14.

[0063] Furthermore, the height adjustment drive mechanism includes a height adjustment mounting bracket 16 and a height electric push rod 17. The height adjustment mounting bracket 16 is connected to the telescopic rod of the height electric push rod 17, and the cutting drive motor 15 is mounted on the height adjustment mounting bracket 16.

[0064] With the above structure, when encountering different ridge heights, the height adjustment mounting bracket 16 is driven by the height electric push rod 17 to move vertically, thereby adjusting the height of the cutting wheel 14 to adapt to different occasions.

[0065] See Figure 1-3 and Figure 12-14 The vertical stacking mechanism includes a vertical stacking frame 18, a conveying stacking assembly, and a limiting stacking assembly; two vertical stacking frames 18 are provided, both vertically arranged, and a vertical stacking channel 19 is provided between the two vertical stacking frames 18; the vertical discharge mechanism is located behind the vertical stacking channel 19; the conveying stacking assembly includes stacking fingers 20, a conveying stacking transmission structure, and a conveying stacking drive motor 21; the conveying stacking transmission structure includes a conveying stacking rotating shaft, a conveying stacking transmission chain 22, and two conveying stacking transmission sprockets; multiple stacking fingers 20 are provided and are arranged on the conveying stacking transmission chain 22; two conveying stacking rotating shafts are provided and are vertically rotatably connected to one of the vertical stacking frames 18, and one of the conveying stacking rotating shafts is connected to the output shaft of the conveying stacking drive motor 21; the conveying stacking... A transmission chain 22 is disposed between two conveying and stacking transmission sprockets; the two conveying and stacking transmission sprockets are respectively disposed on two conveying and stacking rotating shafts; the limiting stacking assembly includes a limiting stacking arm 23, a limiting stacking transmission shaft, and a limiting stacking drive motor 24; the limiting stacking transmission shaft is vertically rotatably connected to another vertical stacking frame 18, and the limiting stacking transmission shaft is connected to the output shaft of the limiting stacking drive motor 24; one end of the limiting stacking arm 23 is fixed to the limiting stacking transmission shaft; the limiting stacking arm 23 and the stacking finger 20 are located at different heights; in the stacking working state, the other end of the limiting stacking arm 23 extends laterally to the end of the vertical stacking channel 19, and the stacking finger 20 takes the sugarcane from the supporting conveying mechanism and conveys the sugarcane along the vertical stacking channel 19 to the front of the limiting stacking arm 23.

[0066] With the above structure, driven by the conveying and stacking drive motor 21, the conveying and stacking transmission chain 22 drives the stacking finger 20 to move from the outside to the inside, thereby taking over the sugarcane on the supporting conveying mechanism and conveying it into the vertical stacking channel 19. Since the end of the vertical stacking channel 19 is provided with a limiting stacking arm 23, the sugarcane will be temporarily stacked at the end of the vertical stacking channel 19. When the sugarcane is stacked to a certain amount, the limiting stacking drive motor 24 drives the limiting stacking arm 23 to swing away from the end of the vertical stacking channel 19, and then the stacking finger 20 conveys the sugarcane stack to the vertical discharge mechanism behind.

[0067] See Figure 13-15The stacking finger 20 is rotatably connected to the stacking transmission chain 22. A stacking torsion spring (not shown in the figure) is provided between the stacking finger 20 and the stacking transmission chain 22 to ensure that the stacking finger 20 is perpendicular to the tangential surface of the stacking transmission chain 22. Along the conveying direction, a limiting post 20-1 is provided at the end of the stacking finger 20 near the stacking transmission chain 22 to prevent the stacking finger 20 from rotating backward. The vertical stacking frame 1... The side of 8 is provided with a clearance hole 18-1 for avoiding the stacking finger 20; the upper and lower bottom surfaces of the clearance hole 18-1 are provided with a limiting groove 18-2 that cooperates with the limiting post 20-1; the position of the clearance hole 18-1 corresponding to the end of the vertical stacking channel 19 is covered with a clearance and collapse plate 30 for pushing down the stacking finger 20; the position of the clearance hole 18-1 corresponding to the clearance and collapse plate 30 is not provided with the limiting groove 18-2. With the above structure, when the sugarcane is being fed by the sugarcane gathering finger 20 at the front middle of the vertical gathering channel 19, the limiting post 20-1 of the sugarcane gathering finger 20 slides in the limiting groove 18-2, thus providing stable support for the sugarcane gathering finger 20 and preventing it from swinging backward. When the sugarcane gathering finger 20 moves to the end of the vertical gathering channel 19, the limiting post 20-1 of the sugarcane gathering finger 20 comes out of the limiting groove 18-2 and then hits the avoidance plate 30. The avoidance plate 30 drives the sugarcane gathering finger 20 to swing backward, causing the sugarcane gathering finger 20 to fall onto the feeding and gathering transmission chain 22 and be conveyed forward a certain distance until it passes the avoidance plate 30. Under the action of the gathering torsion spring, the sugarcane gathering finger 20 returns to its normal state. This ingenious method can prevent the sugarcane from blocking the movement of the sugarcane gathering finger 20 while the sugarcane is being piled up.

[0068] Furthermore, the sugarcane stacking finger 20, the stacking transmission chain 22, and the stacking transmission sprocket are provided in two sets and arranged vertically to ensure that the sugarcane can be transported forward vertically.

[0069] See Figure 1-3 and Figure 12The vertical discharge mechanism includes a discharge frame 25, discharge fingers 26, a discharge transmission structure, and a discharge drive motor 27. The discharge frame 25 is vertically arranged, and a discharge channel 28 is provided between the discharge frame 25 and the vertical stacking frame 18. The extension direction of the discharge channel 28 is perpendicular to the extension direction of the vertical stacking channel 19. The discharge transmission structure includes a discharge shaft, a discharge transmission chain 29, and two discharge transmission sprockets. Multiple discharge fingers 26 are provided and are arranged on the discharge transmission chain 29. The distance between two adjacent discharge fingers 26 is greater than the width of the vertical stacking channel 19. Two discharge shafts are provided and are vertically rotatably connected to the discharge frame 25, and one of the discharge shafts is connected to the output shaft of the discharge drive motor 27. The discharge transmission chain 29 is arranged between two discharge transmission sprockets. The two discharge transmission sprockets are respectively arranged on two discharge shafts. With the above structure, when the sugarcane pile enters the discharge channel 28, the discharge drive motor 27 drives the discharge fingers 26 to discharge the sugarcane pile laterally.

[0070] Furthermore, the discharge finger 26, discharge transmission chain 29, and discharge transmission sprocket are provided in two sets and arranged vertically to ensure that the sugarcane can be transported forward vertically.

[0071] See Figure 1-14 The working principle of the vertical harvester for defoliating and stalk-cutting sugarcane in this embodiment is as follows:

[0072] During operation, the sugarcane is processed by removing the leaves, so the influence of the leaves is not considered. The walking drive mechanism drives the walking component 2 to rotate, allowing it to move through the sugarcane field carrying the harvesting execution device. When encountering sugarcane fields with different row spacings, the wheel track adjustment drive mechanism drives the walking mounting frames 3 on both sides to extend or retract, thus obtaining the desired wheel track according to the sugarcane row spacing, adapting to different sugarcane planting row spacings, and providing good flexibility.

[0073] Furthermore, upon approaching the sugarcane, driven by the lifting drive motor, the lifting transmission chain 7 moves the lifting feed finger 6 from the outside to the inside, thereby lifting the tilted sugarcane for subsequent clamping and cutting. Next, driven by the integrated drive motor 12, the integrated transmission chain 13 moves the integrated finger from the outside to the inside, and two sets of oppositely arranged integrated closed-loop rubber clusters 11 simultaneously clamp onto the sugarcane lifted by the lifting feed mechanism, thus continuing to straighten the sugarcane; after the root cutting mechanism cuts the sugarcane, the two sets of oppositely arranged integrated closed-loop rubber clusters 11 hold the sugarcane and convey it backward until it is conveyed to the vertical stacking mechanism.

[0074] Driven by the feeding and stacking drive motor 21, the feeding and stacking transmission chain 22 drives the stacking finger 20 to move from the outside to the inside, thereby taking over the sugarcane on the supporting conveyor and feeding it into the vertical stacking channel 19. Since the end of the vertical stacking channel 19 is equipped with a limiting stacking arm 23, the sugarcane will be temporarily stacked at the end of the vertical stacking channel 19. When the sugarcane is stacked to a certain amount, the limiting stacking drive motor 24 drives the limiting stacking arm 23 to swing away from the end of the vertical stacking channel 19, and then the stacking finger 20 feeds the sugarcane stack to the rear vertical discharge mechanism. The discharge drive motor 27 drives the discharge finger 26 to discharge the sugarcane stack laterally.

[0075] The above are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above content. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.
