[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) The present invention provides a two-way clamping and conveying device for a sugarcane cutter and pavers. The cut sugarcane is moved outwards by a clamping and conveying toothed chain, and is conveyed to one side of the harvested sugarcane ridge by the two-way clamping and conveying device, so that the sugarcane is conveyed outwards over the U-shaped frame and neatly laid horizontally on the empty sugarcane field where the sugarcane has been harvested. By adjusting the two-way clamping and conveying mechanism to move left and right in the horizontal direction, the cut sugarcane is laid on the left or right side according to the terrain.

[0026] The specific implementation modes of the present invention are described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific implementation modes.

[0027] Unless explicitly 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 components.

[0028] like Figures 1 to 6 As shown, a bidirectional sugarcane cutter and paver clamping and conveying device according to a specific embodiment of the present invention comprises a fixed frame 1, a clamping and conveying lifting frame 2, a U-shaped frame 3, a front clamping and conveying rubber roller chain set 4 and a rear clamping and reversing device 5. The fixed frame 1 is provided with a front end of a frame 6 of the cutter and paver.

[0029] The bidirectional clamping and conveying device comprises a fixed frame 1, a clamping and conveying lifting frame 2, a U-shaped frame 3, a front clamping and conveying rubber roller chain group 4 and a rear clamping and reversing device 5. The front end of the frame 6 is provided with a fixed frame 1, and vertical guide rails are provided on both sides of the fixed frame 1. The clamping and conveying lifting frame 2 can be lifted and lowered on the fixed frame 1, located on the guide rails, and connected to a driving member, and the driving member is a hydraulic cylinder or a cylinder. In this embodiment, a hydraulic cylinder is used, and the clamping and conveying lifting frame 2 can be lifted and lowered on the guide rails by hydraulically driving the hydraulic cylinder. According to the terrain conditions or the needs of the work, the distance between the clamping and conveying lifting frame 2 and the ground can be adjusted as a whole. The clamping and conveying lifting frame 2 is fixedly connected with a U-shaped frame 3 by bolts, and the U-shaped frame 3 comprises a left U-shaped frame 31 and a right U-shaped frame 32, and the left U-shaped frame 31 and the right U-shaped frame 32 are respectively connected to the clamping and conveying lifting frame 1, and are respectively located on the left and right sides of the front end of the frame. The left U-shaped frame 31 and the right U-shaped frame 32 have the same structure. Taking the right U-shaped frame 32 as an example, the opening of the right U-shaped frame faces upward, the U-shaped groove faces downward, and is arranged close to the body surface. The U-shaped groove of the frame body is the sugarcane outlet 33.

[0030] The front clamping conveying rubber roller chain group 4 includes a left rubber roller chain 41 and a right rubber roller 42. The left rubber roller chain 41 and the right rubber roller 42 have the same structure and installation method, and the rubber rollers on the left rubber roller chain 41 are placed in a vertical direction. The left rubber roller chain 41 and the right rubber roller chain 42 are arranged side by side on the U-shaped frame 1 in a left-right relative manner. That is, the left rubber roller chain 41 is installed on the left U-shaped frame 31, and the right rubber roller chain 42 is installed on the right U-shaped frame 32. The left rubber roller chain 41 and the right rubber roller chain 42 are arranged side by side on the same horizontal line, located above the U-shaped groove of the U-shaped frame, and are arranged near the discharge end of the tooth-shifting straightening mechanism 2. The distance space between the left rubber roller chain 41 and the right rubber roller 42 forms a sugarcane inlet, and the cut sugarcane enters the conveying channel through the sugarcane inlet.

[0031] A rear clamping reversing device 5 is provided at the rear side of the front clamping and conveying rubber roller chain group 4. The rear clamping reversing device 5 includes a rear clamping reversing mechanism 51 and a first rear clamping and conveying toothed chain 52. The rear clamping reversing mechanism 51 is arranged on the clamping and conveying lifting frame 1 and can move horizontally left and right. The first rear clamping and conveying toothed chain 52 is arranged on the rear clamping reversing mechanism 51, located at the rear side of the front clamping and conveying rubber roller chain group 4, and forms an upper left sugarcane conveying channel and an upper right sugarcane conveying channel between the left rubber roller chain 41 and the right rubber roller chain 42. The teeth of the first rear clamping and conveying toothed chain 52 are arranged toward one side of the front clamping and conveying rubber roller chain group 4. The front clamping adopts wear-resistant rubber rollers to squeeze and clamp the sugarcane, so that the sugarcane is kept in a clamped state without damaging the damaged sugarcane. The rear clamping structure adopts a chain-carrying toothed structure, and the sugarcane is conveyed left and right by the teeth in a flexible clamping state.

[0032] During transportation, the sugarcane is in a vertical state and enters through the sugarcane inlet between the left rubber roller chain 41 and the right rubber roller 42. Depending on the actual terrain, the cut sugarcane is laid to the left or right. When it is necessary to lay it to the left, the rear clamping reversing mechanism 51 moves to the left on the clamping conveying lifting frame 1 beyond the left U-shaped frame 31. Since the rubber rollers on the left rubber roller chain 41 and the right rubber roller chain 42 are arranged in a vertical direction, the movement mode of the sugarcane in the upper left sugarcane conveying channel is that the sugarcane is in a horizontal movement and transportation in a vertical state. After being transported to the left U-shaped frame, it is sent out at the sugarcane outlet of the U-shaped groove and laid to the left. However, when it is necessary to lay it to the right, the working mode is also the same, except that the rear clamping reversing mechanism 51 moves to the right on the clamping conveying lifting frame 1 beyond the right U-shaped frame 32.

[0033] Preferably, the U-shaped frame 3 is provided with an auxiliary clamping and telescopic mechanism 7, and the auxiliary clamping and telescopic mechanism 7 includes two auxiliary clamping guides. Preferably, the auxiliary clamping and telescopic mechanism is a rod body or a guide groove with a groove. The present embodiment uses a guide groove with a groove. That is, the auxiliary clamping and telescopic mechanism 7 includes two auxiliary clamping guide grooves, namely a left guide groove 71 and a right guide groove 72. The left guide groove 71 is installed on the left U-shaped frame 31 through a spring member 73, and the right guide groove 72 is installed on the right U-shaped frame 32 through a spring member 73. Preferably, two spring members are respectively provided on the left and right sides to improve the stability of the connection. The left guide groove 71 is correspondingly placed directly below the left rubber roller chain 41, and the right guide groove 72 is correspondingly placed directly below the right rubber roller chain 42. The left guide groove 71 and the right guide groove 72 are arranged side by side on the same horizontal line, and there is a distance space between them, forming a sugarcane entry channel 74. The sugarcane inlet channel 74, the sugarcane inlet between the left rubber roller chain 41 and the right rubber roller 42, and the sugarcane outlet of the tooth-sliding straightening mechanism 2 are in the same vertical direction. The rear clamping reversing mechanism 51 is provided with a second clamping and conveying tooth-sliding chain 53, which is located at the rear side of the auxiliary clamping guide groove and below the first clamping and conveying tooth-sliding chain 52. The second clamping and conveying tooth-sliding chain 53 and the left guide groove 71 and the right guide groove 72 form a left conveying channel and a lower right conveying channel.

[0034] When conveying, the sugarcane is in a vertical state, and the middle and lower parts of the sugarcane enter through the sugarcane inlet 74 between the left guide groove 71 and the right guide groove 72. When conveying the sugarcane to the left, the middle and lower parts of the sugarcane are moved by the second clamping and conveying tooth chain 53, placed in the lower left sugarcane conveying channel, and conveyed out through the conveyor belt of the second clamping and conveying tooth chain 53 to be laid to the left. During the conveying process, the middle and upper parts of the sugarcane are clamped and conveyed by the left rubber roller chain 41 and the first clamping and conveying tooth chain 52, and the middle and lower parts are clamped and conveyed by the left guide groove 71 and the second clamping and conveying tooth chain 53, which improves the stability of the sugarcane conveying process. The working principle of conveying sugarcane to the right is the same as that of conveying sugarcane to the left. Since the left guide groove 71 and the left U-shaped frame 31 are connected by the spring member 73, when the left guide groove 71 clamps the sugarcane, the clamping force is just enough to clamp the sugarcane without damaging the sugarcane, which helps to smoothly convey the sugarcane beyond the U-shaped frame.

[0035] Preferably, the spring member is an inner spring telescopic cylinder. The inner spring telescopic cylinder 73 includes a cylinder body 731 and a cylinder cover 732. A cavity is provided in the middle of the cylinder body. A cylinder cover is provided at one end of the cylinder body and an opening is provided at the other end. The spring 733 is provided in the cavity of the cylinder body 731, one end of the spring 733 is fixed to the cylinder cover 732, and the other end is connected to the telescopic shaft 734. The other end of the telescopic shaft 734 extends outward from the open end of the cylinder body. During installation, the cylinder cover of the inner spring telescopic cylinder is fixed to the U-shaped frame 3, and the telescopic shaft 734 is connected to the auxiliary clamping guide.

[0036] Preferably, the left and right sides of the auxiliary clamping guide are respectively provided with arc-shaped sugarcane guide plates 75. The arc-shaped sugarcane guide plates 75 are conducive to guiding the sugarcane to enter and transport without damaging the sugarcane.

[0037] Preferably, the sugarcane outlet of the U-shaped frame is provided with an inclined plate slope. The left U-shaped frame 31 and the right U-shaped frame 32 have the same structure. Taking the right U-shaped frame as an example, the sugarcane outlet 33 of the right U-shaped frame 32 is provided with an inclined plate slope. The U-shaped frame adopts an inclined plate slope to allow the sugarcane to pass better and is not easy to be blocked here. An arc-shaped guide plate 34 is provided on the outside. The arc-shaped guide plate 34 has a limiting effect on the sugarcane. The sugarcane is discharged from the sugarcane outlet 33. The guide plate 34 limits the sugarcane to gather in the middle so that it will not be too scattered when lodging.

[0038] Preferably, the rear clamping reversing mechanism 51 includes a frame body 511, a rack shaft 512, a mounting seat 513 and a driving assembly. The rack shaft 512 is horizontally mounted on the frame body 511, and a sleeve 514 is sleeved on the rack shaft 512. 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. The selection of a hexagonal rack shaft for the rack shaft 512 can make it difficult for the equipment to move during operation and run smoothly. The sleeve 514 is fixedly connected to the mounting seat 513, and the mounting seat 513 is connected to the clamping conveying lifting frame 1. The driving assembly includes a power member 515 and a gear 516, preferably the power member is a hydraulic motor, and the gear 516 is connected to the output end of the hydraulic motor. The gear 516 is arranged corresponding to the rack shaft 512, and meshes with the rack shaft 512 for transmission. The hydraulic motor drives the gear 516 to rotate, and the gear 516 and the rack shaft 512 mesh with each other to drive the frame 511 to move left and right in the horizontal direction.

[0039] A rear clamping reversing mechanism 51 is provided on the bidirectional clamping and conveying device. The rear clamping and reversing mechanism 51 is composed of a hexagonal rack shaft, a hexagonal sleeve, a gear, a hydraulic motor, and a hydraulic motor mounting seat. The hydraulic motor is installed on the clamping and conveying lifting frame by bolts through the hydraulic motor mounting seat. Both ends of the hexagonal rack shaft are installed on the rear clamping and conveying chain bracket. The motor transmission drives the gear rack to move left and right to adjust the rear clamping and conveying gear chain to move left and right, so as to convey 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 track crushing the sugarcane. The left and right lateral movement device is mainly used to allow the sugarcane to be conveyed far enough. Secondly, when it is not necessary to transfer when working on the ground, the recovery can reduce the width of the machine, so as to achieve the characteristics of compact and miniaturized structure of the bidirectional harvesting mechanism.

[0040] Preferably, a support rod 516 is provided on the frame 511, and the support rod 516 and the rack shaft 512 are arranged parallel to each other and are located below the rack shaft 512. At least one rolling roller 517 is provided on the U-shaped frame 3. In this embodiment, two rolling rollers are provided. The support rod 56 is provided on the rolling roller 517. When the frame 511 moves left and right in the horizontal direction, the rolling roller 517 plays a certain supporting role on the frame 51, and does not hinder the movement of the frame, so that the frame moves smoothly.

[0041] Preferably, an auxiliary dial 54 is provided on the rear clamping reversing mechanism 51, and at least two auxiliary dials are provided, and two are provided in this embodiment. Two auxiliary dials 54 are provided on the rear clamping reversing mechanism 51, and are located above the first clamping and conveying gear chain 52. 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 54 includes a rotating shaft 541, a fixed dial 542 and a plurality of glue sticks 543, and four agitators 543 are provided in this embodiment. The rotating shaft 541 is provided on the rear clamping reversing mechanism 51, and the fixed disk 542 is provided on the rotating shaft 541. The plurality of agitators 543 are evenly distributed around the fixed disk 542, and are arranged in a cross-shaped distribution.

[0042] 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 rubber 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 normally laid on the ground.

[0043] The clamping and conveying mechanism of the present invention is installed on the mower and paver to work in coordination with other components on the mower and paver. The frame 6 is also provided with a double helical mechanism 8, a tooth-sliding straightening mechanism 9, a cutting disc mechanism 10 and a sugarcane tail leaf-crushing mechanism 11. The double helical mechanism 8 is arranged at the front of the frame 6 and is used to lift and straighten the sugarcane. The tooth-sliding straightening mechanism 9 is arranged above the double helical mechanism 8 and is used to straighten the sugarcane and convey the sugarcane to the next process. The cutting disc mechanism 10 is located below the tooth-sliding straightening mechanism 9 and is used to cut off the root of the sugarcane. The bidirectional clamping and conveying device is arranged behind the tooth-sliding straightening mechanism 9 and above the cutting disc mechanism 10 and is used to receive the sugarcane conveyed into the mower and pave the cut sugarcane to the left or right according to the terrain characteristics. The sugarcane tail leaf-crushing mechanism 11 is arranged above the tooth-sliding straightening mechanism 9 and is used to remove the sugarcane tip.

[0044] The working principle of the bidirectional cutting and paving machine of the present invention is as follows: the cutting and paving machine walks across the sugarcane row. During the working and walking process, the front double-screw mechanism 8 in front lifts up the sugarcanes lying on both sides of the sugarcane row. The lifted sugarcanes and the upright sugarcanes are sent to the bidirectional clamping and conveying device by the tooth chain on the tooth straightening mechanism 9. At the same time, these sugarcanes are cut off by the cutting disc 10 on the sugarcane ridge surface, and the tail is hit and crushed by the tail leaf crushing mechanism 11 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 device, so that the sugarcane is transported beyond 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 device to move left and right in the horizontal direction, the sugarcane is cut and laid to the left or right according to the terrain.

[0045] The foregoing description of specific exemplary embodiments of the present invention is for the purpose of illustration and demonstration. These descriptions are not intended to limit the present invention to the precise form disclosed, and it is clear that many changes and variations can be made based on the above teachings.
