Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery and equipment, in particular to a bidirectional sugarcane cutter and paver. Background Art

[0002] Because the sugarcane growing areas of Guangxi and Yunnan are primarily hilly, with 70% of the plots small and scattered, existing segmented and whole-stem combine harvesters fall short of the harvest quality expectations of sugarcane producers and farmers. Promoting a step-by-step mechanized harvesting model characterized by "high-efficiency harvesting, low loss rate, and efficient weed removal" is a more suitable and readily accepted mechanical harvesting method for the geographical conditions of Guangxi and Yunnan, and a new, effective mechanized harvesting method for sugarcane harvesting in hilly areas, creating an urgent market demand.

[0003] Existing sugarcane harvesters and spreaders can only lay the sugarcane in a certain direction after cutting, with a U-shaped or parallel trajectory, resulting in low efficiency. After harvesting, the sugarcane can usually only be laid in one direction, not in both directions. After harvesting a row, the machine must reverse and walk a distance, or harvest in an outer circle, which is inefficient. The top cutting effect is poor on sugarcane with uneven heights, which affects subsequent leaf stripping and weed removal. Harvesting of fallen sugarcane is inefficient or impossible, affecting cutting quality.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) The utility model is a bidirectional sugarcane cutter and spreader. The cutter and spreader moves across the sugarcane row. During the working process, the front end of the front side falls to the ground and lifts up the sugarcane on both sides of the sugarcane row. The lifted sugarcane and the upright sugarcane are sent to the bidirectional clamping and conveying mechanism by the tooth chain on the tooth straightening mechanism. At the same time, these sugarcanes are cut by the cutting disc on the sugarcane ridge surface, and the tail is hit and crushed by the tail leaf breaking mechanism and thrown back into the field. The cut sugarcane is transported outward by the clamping and conveying tooth chain and is transported to the side of the harvested sugarcane ridge by the bidirectional clamping and conveying mechanism. The sugarcane is transported outward over the U-shaped frame and neatly laid horizontally on the empty sugarcane field where the sugarcane has been harvested. By adjusting the bidirectional clamping and conveying mechanism to move left and right in the horizontal direction, the sugarcane is cut and spread to the left or right side according to the terrain.

[0019] (2) The utility model of the bidirectional sugarcane harvester can harvest sugarcane along an S-shaped track, solving the problem of low efficiency caused by the existing sugarcane harvesters that need to reverse and walk a distance or harvest around the outer circle after harvesting a row on one side. The whole machine adopts a modular structure, which fully considers the characteristics of easy disassembly and assembly, and simple maintenance and repair. The crawler walking system can make the machine work and move better and more stably in the work site, and better adapt to hilly terrain. The sugarcane tail leaf shredding mechanism uses a leaf shredding rope to hit the tender sugarcane tail, and also shreds the tail sugarcane leaves, providing good conditions for subsequent leaf stripping and impurity removal work, and reducing the impurity content of sugarcane.

[0020] (3) The utility model is a practical two-way clamping and conveying device. The rear clamping mechanism uses a motor to drive the gear rack to move horizontally to the left and right to convey the sugarcane. This can reduce the width of the machine and achieve a compact and miniaturized two-way harvesting mechanism. The front clamping uses wear-resistant rubber rollers to squeeze and clamp the sugarcane, so that the sugarcane remains clamped without damaging it. The rear clamping structure uses a chain-carried tooth structure to convey the sugarcane to the left and right through the teeth in a flexible clamping state. The rear clamping and conveying mechanism uses a two-layer chain tooth structure, which can better and more stably clamp and convey the sugarcane. Both tall and short sugarcanes can be harvested and conveyed.

[0021] (4) The utility model of a bidirectional sugarcane cutter and spreader can lay the cut sugarcane in both directions and harvest the sugarcane along an S-shaped trajectory, thereby reducing idle time, improving work efficiency, and reducing work costs. The tail leaf shredder mechanism can freely raise and lower the leaf shredding height to a range of 1.5 meters to 3.8 meters through a two-stage lifting system. The leaf shredder rope is used to hit the tender and delicate sugarcane tails of varying heights and break up the tail sugarcane leaves, thereby reducing the workload of the subsequent leaf stripping and impurity removal process and reducing the impurity content.

[0022] (5) The utility model mower and paving machine can adjust the height of the cutting disc in real time according to the terrain, realizing flat soil or in-soil cutting, controlling the size of in-soil cutting, reducing the rate of perennial root head breakage, and improving the perennial root germination rate. The crawler chassis design allows for flexible steering and movement, making it suitable for operations in most hilly and mountainous areas, greatly improving reliability and adaptability.

[0031] The specific implementation of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific implementation.

[0032] Unless expressly stated otherwise, throughout the specification and claims, the term "comprise" or variations such as "include" or "comprising", etc., will be understood to include the stated elements or components but not to exclude other elements or other components.

[0033] like Figures 1 to 8As shown, a bidirectional sugarcane harvester and paving machine according to a specific embodiment of the present invention includes a frame 1, on which is provided a power assembly 2, a traveling mechanism 3, and a cab 4. The traveling mechanism 3 is a crawler-type or wheeled type. This embodiment uses a crawler-type traveling mechanism and a crawler-type chassis, which are flexible in steering and movement and suitable for most operations in hilly and mountainous areas, greatly improving reliability and adaptability. The frame 1 also includes a double-screw mechanism 5, a gear-sliding and straightening mechanism 6, a cutting disc mechanism 7, a bidirectional clamping and conveying device 8, and a sugarcane tail leaf shredding mechanism 9. The double-screw mechanism 5 is located at the front of the frame 1 and is used to lift and straighten the sugarcane. The gear-sliding and straightening mechanism 6 is located above the double-screw mechanism 5 and is used to straighten the sugarcane and convey it to the next process. The cutting disc mechanism 7 is located below the gear-sliding and straightening mechanism 6 and is used to cut the roots of the sugarcane. A bidirectional gripping and conveying device 8 is located behind the tooth-sliding and straightening mechanism 6 and above the cutting disc mechanism 7. It receives the sugarcane delivered by the tooth-sliding and straightening mechanism and lays the cut sugarcane to the left or right depending on the terrain. A sugarcane tip shredder 9 is located above the tooth-sliding and straightening mechanism 6 and is used to remove the sugarcane tips.

[0034] The harvester and spreader moves across the rows of sugarcane. During operation, the front-end double-screw mechanism 5 lifts up fallen sugarcane on either side of the row. The lifted sugarcane, along with the upright sugarcane, is then moved by the toothed chain on the toothed straightening mechanism 6 to a bidirectional gripping conveyor 8. Simultaneously, the sugarcane is severed by the cutting disc 7 on the ridge surface, and the tail ends are pulverized and scattered back into the field by the tail-end leaf shredder 9. The severed sugarcane is then transported outward by the gripping and conveying toothed chain and conveyed by the bidirectional gripping conveyor 8 to the side of the harvested sugarcane ridge where the machine has already harvested it. The sugarcane is then transported beyond the U-shaped frame and neatly laid horizontally onto the cleared sugarcane field. By adjusting the horizontal movement of the bidirectional gripping conveyor 8 to the left or right, the cut sugarcane cane is laid according to the terrain.

[0035] Preferably, the gear shifting and straightening mechanism includes two straightening frames (a left straightening frame 61 and a right straightening frame 62), a gear shifting chain 63 and a power piece 64. The left straightening frame 61 and the right straightening frame 62 are arranged relative to each other and tilted, with the lower end being the feed end and the upper end being the discharge end, and the opening of the feed end is larger than the discharge end. That is, the left straightening frame 21 and the right straightening frame 22 are arranged in an inclined figure eight shape, and the discharge end corresponds to the bidirectional clamping conveying device 8. A gear shifting chain 63 is arranged around each straightening frame, and the transmission directions of the two gear shifting chains 63 are relatively transmitted. The gear shifting chain 63 is connected to the power piece 64, and the power piece 64 is preferably a hydraulic motor. The gear shifting chain 63 is driven to rotate by the hydraulic motor.

[0036] When transporting sugarcane, the cutting disc mechanism 7 cuts off the roots of the sugarcane, and the sugarcane straightened by the double spiral mechanism 5 is placed between the left straightening frame 61 and the right straightening frame 62. The sugarcane is stuck in the space between the teeth on the tooth chain 63. The sugarcane is conveyed to the discharge end by the tooth chain 63 in the opposite conveying direction and enters the bidirectional clamping conveying device 8.

[0037] The specific structure of the bidirectional clamping and conveying device is as follows:

[0038] The bidirectional clamping and conveying device 8 includes a clamping and conveying lifting frame 81, a U-shaped frame 82, a front clamping and conveying rubber roller chain assembly 83, and a rear clamping and reversing device 84. A fixed frame 11 is provided at the front end of the vehicle frame 1, with vertical guide rails provided on both sides of the fixed frame 11. The clamping and conveying lifting frame 81 is arranged on the fixed frame 11 so as to be liftable, located on the guide rails, and connected to a drive member 811, which is a hydraulic cylinder or a pneumatic cylinder. In this embodiment, the hydraulic cylinder is used to hydraulically drive the clamping and conveying lifting frame 81 so as to be liftable and movable up and down on the guide rails. The distance between the clamping and conveying lifting frame 81 and the ground can be adjusted as a whole according to terrain conditions or work needs. The U-shaped frame 82 is fixedly connected to the clamping and conveying lifting frame 81 by bolts. The U-shaped frame 82 includes a left U-shaped frame 821 and a right U-shaped frame 822. The left U-shaped frame 821 and the right U-shaped frame 822 are respectively connected to the clamping and conveying lifting frame 81 and are located on the left and right sides of the front end of the vehicle frame 1. The left U-shaped frame 821 and the right U-shaped frame 822 have the same structure. Take the right U-shaped frame 822 as an example for explanation, the right U-shaped frame has an opening facing upwards, a U-shaped groove facing downwards, and is arranged close to the surface. The U-shaped groove of the frame body is a sugarcane outlet 823.

[0039] The front clamping and conveying rubber roller chain assembly 83 comprises a left rubber roller chain 831 and a right rubber roller chain 832. The left and right rubber roller chains 831 and 832 have identical structures and mounting arrangements, with the rollers on the left rubber roller chain 831 positioned vertically. They are arranged side by side, facing each other, on the U-shaped frame 81. Specifically, the left rubber roller chain 831 is mounted on the left U-shaped frame 821, while the right rubber roller chain 832 is mounted on the right U-shaped frame 822. The left and right rubber roller chains 831 and 832 are arranged side by side on the same horizontal plane, located above the U-shaped groove of the U-shaped frame and near the discharge end of the tooth-sliding and straightening mechanism 6. The space between the left and right rubber roller chains 831 and 832 forms the sugarcane inlet, where the sugarcane enters after being straightened and conveyed to the discharge end by the tooth-sliding and straightening mechanism 6.

[0040] A rear clamping and conveying rubber roller chain assembly 83 is equipped with a rear clamping and reversing device 84. The rear clamping and reversing device 84 comprises a rear clamping and reversing mechanism 841 and a first rear clamping and conveying shifting gear chain 842. The rear clamping and reversing mechanism 841 is mounted on the clamping and conveying lifting frame 81 and is capable of horizontally moving left and right. The first rear clamping and conveying shifting gear chain 842 is mounted on the rear clamping and reversing mechanism 841 and is located behind the front clamping and conveying rubber roller chain assembly 83. Together with the left and right rubber roller chains 831 and 832, the shifting gears of the first rear clamping and conveying shifting gear chain 842 are positioned toward one side of the front clamping and conveying rubber roller chain assembly 83. The front clamping mechanism utilizes wear-resistant rubber rollers to squeeze and clamp the sugarcane, keeping it firmly clamped without damaging it. The rear clamping mechanism utilizes a chain-carried shifting gear structure, which allows the shifting gears to deliver the sugarcane to the left and right sides while maintaining a flexible grip.

[0041] During conveying, the sugarcane is held in a vertical position, entering through the sugarcane inlet between the left and right rubber roller chains 831 and 832. Depending on the terrain, the cut sugarcane is laid out to the left or right. To lay out the sugarcane to the left, the rear clamping and reversing mechanism 841 on the clamping and conveying hoist 81 is moved to the left, beyond the left U-shaped frame 821. Because the rollers on the left and right rubber roller chains 831 and 832 are arranged vertically, the sugarcane moves horizontally in the upper left conveyor channel while in a vertical position. After being conveyed to the left U-shaped frame, it is discharged through the sugarcane outlet of the U-shaped trough and laid out to the left. To lay out the sugarcane to the right, the same procedure is followed, except that the rear clamping and reversing mechanism 841 on the clamping and conveying hoist 81 is moved to the right, beyond the right U-shaped frame 822.

[0042] Preferably, the U-shaped frame 82 is equipped with an auxiliary clamping and retracting mechanism 85, which includes two auxiliary clamping guides. Preferably, the auxiliary clamping guides are rods or guide slots with grooves. In this embodiment, guide slots with grooves are used. Specifically, the auxiliary clamping and retracting mechanism 85 includes two auxiliary clamping guides: a left guide slot 851 and a right guide slot 852. The left guide slot 851 is mounted on the left U-shaped frame 821 via a spring member 853, while the right guide slot 852 is mounted on the right U-shaped frame 822 via a spring member 853. Preferably, two spring members are provided on each side to enhance connection stability. The left guide slot 851 is positioned directly below the left rubber roller chain 831, while the right guide slot 852 is positioned directly below the right rubber roller chain 832. The left and right guide slots 851 and 852 are arranged side by side on the same horizontal line, with a space between them, forming a sugarcane inlet channel 854. The sugarcane inlet channel 854, the sugarcane inlet between the left and right rubber roller chains 831 and 832, and the sugarcane outlet of the shifter straightening mechanism 2 are all aligned vertically. The rear clamping and reversing mechanism 841 is equipped with a second clamping and conveying shifter chain 843, located behind the auxiliary clamping guide groove and below the first rear clamping and conveying shifter chain 842. The second clamping and conveying shifter chain 843, along with the left and right guide grooves 851 and 852, forms a left conveying channel and a lower right conveying channel.

[0043] During conveyance, the sugarcane is held upright, with the lower and middle portions entering through the sugarcane inlet 854 between the left guide trough 851 and the right guide trough 852. When conveying to the left, the lower and middle portions of the sugarcane are moved by the second clamping and conveying gear chain 843, placed in the lower left conveying channel, and then conveyed out on the conveyor belt of the second clamping and conveying gear chain 843 to be laid out to the left. During conveyance, the upper and middle portions of the sugarcane are clamped and conveyed by the left rubber roller chain 831 and the first rear clamping and conveying gear chain 842, while the lower and middle portions are clamped and conveyed by the left guide trough 851 and the second clamping and conveying gear chain 843, improving the stability of the sugarcane conveying process. The operating principle of conveying sugarcane to the right is the same as that of conveying sugarcane to the left. The left guide groove 851 and the left U-shaped frame 821 are connected by a spring member 853. When the left guide groove 851 clamps the sugarcane, the clamping force is just enough to clamp the sugarcane without damaging it, thereby helping to smoothly send the sugarcane out over the U-shaped frame.

[0044] Preferably, the spring member is an inner spring telescopic cylinder. The inner spring telescopic cylinder 853 comprises a cylinder body 8531 and a cylinder cover 8532. The cylinder body has a cavity in the middle, a cylinder cover at one end, and an opening at the other. Spring 8533 is positioned within the cavity of cylinder body 8531, with one end secured to cylinder cover 8532 and the other end connected to a telescopic shaft 8534, the other end of which extends outward from the open end of the cylinder body. During installation, the cylinder cover of the inner spring telescopic cylinder is secured to the U-shaped frame 82, and the telescopic shaft 8534 is connected to the auxiliary clamping guide.

[0045] Preferably, the left and right sides of the auxiliary clamping guide are respectively provided with an arc-shaped sugarcane guide plate 855. The arc-shaped sugarcane guide plate 855 is conducive to guiding the sugarcane into the conveying without damaging the sugarcane.

[0046] The sugarcane outlet of the U-shaped frame is preferably configured with an inclined plate slope. The left U-shaped frame 821 and the right U-shaped frame 822 have the same structure. Taking the right U-shaped frame as an example, the sugarcane outlet 823 of the right U-shaped frame 822 is configured with an inclined plate slope. This inclined plate slope design allows for easier passage of sugarcane and reduces the risk of blockage. Curved guide plates 824 are provided on the outside to limit the sugarcane flow. As the sugarcane is discharged from the outlet 823, the guide plates 824 confine the sugarcane to the center, preventing it from spreading outward when it falls.

[0047] Preferably, the rear clamping reversing mechanism 841 includes a frame 8411, a rack shaft 8412, a mounting seat 8413, and a drive assembly. The rack shaft 8412 is mounted horizontally on the frame 8411, and a sleeve 8415 is provided on the rack shaft 8412. Preferably, the rack shaft is a hexagonal rack shaft, and the sleeve is a hexagonal sleeve. The rack of the rack shaft is located on the lower surface of the shaft body. Using a hexagonal rack shaft for the rack shaft 8412 prevents movement during operation, ensuring smooth operation. The sleeve 8415 is fixedly connected to the mounting seat 8413, and the mounting seat 843 is connected to the clamping, conveying, and lifting frame 81. The drive assembly includes a power member 8415 and a gear 8416. Preferably, the power member is a hydraulic motor, and the gear 8416 is connected to the output end of the hydraulic motor. The gear 8416 is arranged corresponding to the rack shaft 8412 and meshes with the rack shaft 8412 for transmission. The hydraulic motor drives the gear 8416 to rotate, and the gear 8416 and the rack shaft 8412 are meshed with each other to drive the frame 8411 to move left and right in the horizontal direction.

[0048] The bidirectional clamping and conveying device is provided with a rear clamping and reversing mechanism 841, which consists of a hexagonal rack shaft, a hexagonal sleeve, a gear, a hydraulic motor, and a hydraulic motor mounting seat. The hydraulic motor is mounted on the clamping and conveying lifting frame by bolts through the hydraulic motor mounting seat. The two ends of the hexagonal rack shaft are mounted on the rear clamping and conveying chain bracket. The motor drives the gear rack to move left and right to adjust the left and right movement of the rear clamping and conveying gear chain, thereby conveying the sugarcane left and right. For example, if the sugarcane needs to be conveyed to the right, the rear clamp is moved to the right beyond the U-shaped frame, so that the sugarcane is conveyed beyond the U-shaped frame and spread out on the ground, so that there is no need to worry about the tracks crushing the sugarcane. The left and right lateral movement device is mainly used to ensure that the sugarcane is conveyed far enough. Secondly, when the machine needs to be transferred when not working in the field, the recovery can reduce the width of the machine, thus realizing the compact and miniaturized structure of the bidirectional harvesting mechanism.

[0049] Preferably, the frame 8411 is provided with a support rod 8416, which is arranged parallel to the rack shaft 8412 and located below the rack shaft 8412. The U-shaped frame 82 is provided with at least one rolling roller 8417. In this embodiment, two rolling rollers are provided. The support rod 8416 is mounted on the rolling roller 8417. When the frame 8411 moves horizontally, the rolling roller 8417 provides a certain degree of support for the frame 8411 without hindering its movement, ensuring smooth movement.

[0050] Preferably, an auxiliary dial 86 is provided on the rear clamping reversing mechanism 841, and there are at least two auxiliary dials, and there are two in this embodiment. The two auxiliary dials 86 are provided on the rear clamping reversing mechanism 841, and are located above the first rear clamping conveying gear chain 842. The two auxiliary dials are distributed at a certain distance, and when cutting and paving operations are performed, one of the auxiliary dials is located at the discharge end of the gear straightening mechanism 2. Preferably, the auxiliary dial 86 includes a rotating shaft 861, a fixed dial 862 and a plurality of glue sticks 863, and there are four stirring sticks 863 in this embodiment. The rotating shaft 861 is provided on the rear clamping reversing mechanism 841, and the fixed disk 862 is provided on the rotating shaft 861. The plurality of stirring sticks 863 are evenly distributed around the fixed disk 862 and are arranged in a cross shape.

[0051] The main function of the auxiliary dial is to assist the normal transportation of sugarcane to the clamping and conveying area through the rotation of the glue stick. There are two auxiliary dials. When the rear clamping reversing is completed, one dial will be in the middle of the entire clamping conveyor belt to assist in pushing the sugarcane into the clamping and conveying direction. The other set will be at the rear end in the conveying direction to assist in pushing the sugarcane out of the U-shaped frame so that the sugarcane can smoothly exceed the crawler walking area and be laid normally on the ground.

[0052] The specific structure of sugarcane tail leaf shredder is as follows:

[0053] The sugarcane tip leaf shredder mechanism 9 includes a leaf shredder frame 91, a lifting mechanism 92, and a leaf shredder mechanism 93. The leaf shredder frame 91 is mounted on the fixed frame 11 of the vehicle frame 1. Vertical guide rails are provided on both sides of the leaf shredder frame 91. Two lifting mechanisms 92 are mounted on the leaf shredder frame 91, one on each side of the leaf shredder frame 91, ensuring smoother operation. Each lifting mechanism 92 includes a primary telescopic lifting rod 921, a secondary lifting chain 922, a sprocket 923, and a lifting frame 924. The sprocket 923 is located at the upper end of the leaf shredder frame 91. The primary telescopic lifting rod 921 is a pneumatic or oil cylinder telescopic rod.

[0062] Preferably, the double screw mechanism 5 comprises a pair of screw rods arranged in an eight-shaped pattern, with the screw rods tilted at an angle of 15-30 degrees. The appropriate tilt angle of the double screw mechanism 5 can lift the fallen sugarcane as much as possible for mechanical cutting and paving.

[0063] The working principle of the bidirectional cutter and pavers of the utility model is as follows: the cutter and pavers move across the sugarcane rows, and during the working and walking process, the front-end double-helix mechanism lifts up the sugarcanes lying on both sides of the sugarcane rows, and the lifted sugarcanes are sent to the bidirectional clamping and conveying mechanism together with the upright sugarcanes by the chain teeth on the tooth-sliding straightening mechanism. At the same time, these sugarcanes are cut off by the cutting disc on the sugarcane ridge surface, and the tail ends are hit and crushed by the tail-tip leaf-crushing mechanism and thrown back into the field. The cut sugarcanes are transported outward by the clamping and conveying tooth chain, and are conveyed to the side of the sugarcane ridge that has been harvested by the machine under the transmission of the bidirectional clamping and conveying mechanism, so that the sugarcane is transported outward over the U-shaped frame and neatly laid horizontally on the empty sugarcane field where the sugarcane has been harvested.
