[0002] Since the sugarcane areas in Guangxi and Yunnan are basically hilly areas, 70% of the plots are small and scattered, and the harvesting quality of the existing segmented and whole-stem combine harvesters does not meet the expected requirements of sugar companies and sugarcane farmers. Promoting the step-by-step mechanized harvesting mode of "efficient harvesting + low loss rate + efficient weed removal" is a mechanical harvesting method that is more suitable for the geographical environment of Guangxi and Yunnan, and is easily accepted by sugar companies and sugarcane farmers. It is a new mechanized harvesting mode that effectively solves the problem of sugarcane harvesting in hilly areas, and the market demand is urgent.

After cutting a row, it is necessary to reverse and walk a distance or harvest around the outer circle, which is inefficient. For sugarcanes of different heights, the cutting effect is poor, which affects the subsequent leaf stripping and weed removal effect.

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

[0018] (1) The bidirectional sugarcane cutter and paving machine of the present invention moves across the sugarcane row. During the working and walking process, the front end of the double spiral mechanism lifts up the sugarcane lying 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 off by the cutting blade on the sugarcane ridge surface, and the tail is hit and crushed by the tail leaf crushing 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, 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 mechanism to move left and right in the horizontal direction, the sugarcane is cut and laid on the left or right side according to the terrain.

[0019] (2) The bidirectional sugarcane harvester of the present invention 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, taking into full consideration the characteristics of easy disassembly and assembly and simple maintenance. The crawler-type 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 tip leaf shredder uses a leaf shredder rope to hit the tender sugarcane tail, and also shreds the tail tip sugarcane leaves, providing good conditions for subsequent leaf stripping and impurity removal, thereby reducing the impurity content of the sugarcane.

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

[0021] (4) The bidirectional sugarcane cutter and paving machine of the present invention can lay the cut sugarcane in both directions and harvest the sugarcane in an S-shaped track, thereby reducing the idle time, improving the operation efficiency and reducing the operation cost. The tail leaf shredder mechanism can freely lift the leaf shredder height 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 crisp sugarcane tails of different heights and break the tail sugarcane leaves, thereby reducing the workload of the leaf stripping and impurity removal link in the later process and reducing the impurity content.

[0022] (5) The mower and paving machine of the present invention can adjust the height of the cutting disc in real time according to the terrain, realize soil leveling or soil cutting, control the soil cutting size, reduce the rate of perennial root head breakage, and increase the perennial root germination rate. It is designed as a crawler chassis with flexible steering and movement, suitable for most hilly and mountainous areas, and greatly improves reliability and adaptability.

The tooth-shifting and straightening mechanism 6 is arranged above the double helical mechanism 5, and is used to straighten the sugarcane and convey the sugarcane to the next process. The cutting disc mechanism 7 is located below the tooth-shifting and straightening mechanism 6, and is used to cut off the root of the sugarcane. The bidirectional clamping and conveying device 8 is arranged behind the tooth-sliding and straightening mechanism 6 and above the cutting blade mechanism 7, and is used to receive the sugarcane conveyed by the tooth-sliding and straightening mechanism, and lay the cut sugarcane to the left or right according to the terrain characteristics.

The lifted sugarcanes and the upright sugarcanes are sent to the two-way clamping and conveying device 8 by the tooth chain on the tooth straightening mechanism 6. At the same time, these sugarcanes are cut off by the cutting disc 7 on the sugarcane ridge surface, and the tails are hit and crushed by the tail leaf crushing mechanism 9 and thrown back into the field. The cut sugarcanes are transported outward by the clamping and conveying tooth chain, and are transported to the side of the harvested sugarcane ridge by the two-way clamping and conveying device 8, 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 two-way clamping and conveying device 8 to move left and right in the horizontal direction, the sugarcane is cut and laid on the left or right side according to the terrain.

[0035] Preferably, the gear shifting 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 opposite 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.

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 the root of the sugarcane, and the sugarcane straightened by the double screw 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 opposite to the 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 group 83 and a rear clamping and reversing device 84.

The clamping and conveying lifting frame 81 can be lifted and lowered on the fixed frame 11, located on the guide rails, and connected to a driving member 811, which is a hydraulic cylinder or a cylinder. In this embodiment, the hydraulic cylinder is used to hydraulically drive the clamping and conveying lifting frame 81 to move up and down on the guide rails. According to the terrain conditions or the needs of the work, the distance between the clamping and conveying lifting frame 81 and the ground can be adjusted as a whole. The clamping and conveying lifting frame 81 is fixedly connected with a U-shaped frame 82 by bolts, and 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 respectively located on the left and right sides of the front end of the 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, and the U-shaped groove of the frame body is a sugarcane outlet 823.

[0039] The front clamping conveying rubber roller chain group 83 includes a left rubber roller chain 831 and a right rubber roller 832. The left rubber roller chain 831 and the right rubber roller 832 have the same structure and installation method, and the rubber rollers on the left rubber roller chain 831 are placed in a vertical direction. The left rubber roller chain 831 and the right rubber roller chain 832 are arranged side by side on the U-shaped frame 81 in a left-right relative manner. That is, the left rubber roller chain 831 is installed on the left U-shaped frame 821, and the right rubber roller chain 832 is installed on the right U-shaped frame 822. The left rubber roller chain 831 and the right rubber roller chain 832 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-sliding straightening mechanism 6. The distance space between the left rubber roller chain 831 and the right rubber roller 832 forms a sugarcane inlet, and the sugarcane enters the sugarcane inlet after being straightened and conveyed to the discharge end by the tooth-sliding straightening mechanism 6.

The teeth of the first rear clamping and conveying toothed chain 842 are arranged toward one side of the front clamping and conveying rubber roller chain group 83. 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 toothed structure in a flexible clamping state.

[0041] During transportation, the sugarcane is in a vertical state and enters through the sugarcane inlet between the left rubber roller chain 831 and the right rubber roller 832. 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 841 moves to the left on the clamping conveying and lifting frame 81 beyond the left U-shaped frame 821. Since the rubber rollers on the left rubber roller chain 831 and the right rubber roller chain 832 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 841 moves to the right on the clamping conveying and lifting frame 81 beyond the right U-shaped frame 822.

The rear clamping reversing mechanism 841 is provided with a second clamping and conveying tooth-sliding chain 843, which is located at the rear side of the auxiliary clamping guide groove and below the first clamping and conveying tooth-sliding chain 842. The left conveying channel and the lower right conveying channel are formed between the second clamping and conveying tooth-sliding chain 843 and the left guide groove 851 and the right guide groove 852.

[0043] When conveying, the sugarcane is in a vertical state, and the middle and lower parts of the sugarcane enter through the sugarcane inlet 854 between the left guide groove 851 and the right guide groove 852. When conveying the sugarcane to the left, the middle and lower parts of the sugarcane are moved by the second clamping and conveying toothed chain 843, placed in the lower left sugarcane conveying channel, and conveyed out through the conveyor belt of the second clamping and conveying toothed chain 843 to be laid to the left.

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.
