It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "bottom surface" and "top surface", "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0022] Reference Figure 1-4 As shown, the ramie harvesting and stripping machine includes a frame 1, the frame 1 is equipped with a control console 11, a driving device 2, a conveying device 3 for conveying ramie and a storage box 4 for storing ramie, a harvesting device 5 for cutting the ramie is installed at the front end of the conveying device 3, a stripping device 6 for stripping the ramie is installed at the box opening of the storage box 4, the stripping device 6 is connected to the conveying device 3 and is installed at the rear end of the conveying device 3. When working, the harvesting device 5 cuts the ramie, the conveying device 3 sends the cut ramie to the stripping device 6, and the ramie is stripped by the stripping device 6 and sent to the storage box 4 for storage.

[0023] Through the above scheme, the driving device 2 drives the harvester forward, the harvesting device 5 cuts the ramie, the conveying device 3 drives the ramie to move and convey it to the stripping device 6, the stripping device 6 strips the ramie and puts the stripped ramie into the storage box 4 for storage. By stripping the ramie at the same time as harvesting the ramie, the labor efficiency is improved and the harvesting and processing are convenient. After the ramie is stripped, it can be effectively compressed to reduce the storage volume. The storage box 4 can accommodate more ramie, which can expand the amount of ramie accommodated in disguise and improve the harvesting efficiency.

[0024] As a specific implementation method of the improvement, refer to Figure 3 As shown, the stripping device 6 includes a stripping tube cover 61 fixedly connected to the storage box 4, and a coarse stripping roller group 62, a fine stripping roller group 63 and an adjusting roller 64 are installed in the stripping tube cover 61. The adjusting roller 64 is installed between the coarse stripping roller group 62 and the fine stripping roller group 63.

[0025] Through the above scheme, the harvested ramie is driven by the conveying device 3 to be sent into the stripping tube cover 61, the rough stripping roller group 62 first roughly strips the ramie to break and separate the ramie tissue, and the fine stripping roller group 63 further strips the ramie to separate the ramie fibers. The adjusting roller 64 tensions the ramie to keep the ramie fibers straight and elongated to avoid deformation and ensure the stripping quality.

[0026] As a specific implementation method of the improvement, refer to Figure 3 As shown, the rough stripping roller group 62 includes a first rough stripping roller 621 and a second rough stripping roller 622. The first rough stripping roller 621 is arranged above the second rough stripping roller 622. The first rough stripping roller 621 and the second rough stripping roller 622 are both provided with a plurality of rough stripping protrusions 623 with triangular cross sections.

[0027] Through the above scheme, the ramie is squeezed by several rough stripping protrusions 623 with triangular cross sections, so that the ramie stem is fully squeezed and crushed, and the ramie fiber is separated from the ramie bone and ramie skin. The triangular structure can reduce the gap and fully contact the ramie stem.

[0028] As a specific implementation method of the improvement, refer to Figure 3 As shown, the fine stripping roller group 63 includes a small stripping roller 631 and a large stripping roller 632. The small stripping roller 631 is arranged behind the adjusting roller 64 and is arranged obliquely above and in front of the large stripping roller 632. The adjusting roller 64, the small stripping roller 631 and the large stripping roller 632 are all provided with fine stripping blades 633 of different sizes.

[0029] Through the above scheme, the different sizes of the rollers can make the scraping speed and angle different, so that the ramie fibers can be better separated. The fine stripping blades 633 can scrape the broken ramie bones and ramie skins on the ramie fibers, and even hang the blades on the ramie stems, so that the ramie fibers can be fully separated.

[0030] As a specific implementation method of the improvement, refer to Figure 3 As shown, an arc-shaped protrusion 611 is provided on the stripping tube cover 61 , and the arc-shaped protrusion 611 forms an accommodating cavity for accommodating part of the stripping roller 631 .

[0031] Through the above solution, the arc-shaped protrusion 611 can accommodate the small stripping roller 631, so that the position of the small stripping roller 631 can be adjusted, which is convenient for the ramie fibers to change their moving route and be fully stretched, squeezed and stripped.

[0032] As a specific implementation method of the improvement, refer to Figure 2 As shown, the conveying device 3 is rotatably connected to the stripping device 6, the harvesting device 5 is installed at the front end of the conveying device 3, and a lifting cylinder 12 is also installed on the frame 1, and the lifting end of the lifting cylinder 12 is rotatably connected to the bottom of the conveying device 3.

[0033] Through the above scheme, the conveying device 3 is rotatably connected with the stripping device 6, which can ensure that the conveying device 3 drives the ramie to be smoothly conveyed into the stripping device 6, and there will be no deviation in coordination due to the angle adjustment of the conveying device 3, thereby ensuring the smooth operation of harvesting and stripping. The lifting cylinder 12 can drive the conveying device 3 to rotate, so that the height of the harvesting device 5 at the front end of the conveying device 3 can be adjusted to adjust the cutting height and the conveying angle.

[0034] As a specific implementation method of the improvement, refer to Figure 1 As shown, the conveying device 3 includes a conveying frame 31, which is rotatably connected to the stripping tube cover 61, and a conveying belt 32 and a clamping mechanism 7 are installed on the conveying frame 31. The clamping mechanism 7 includes a clamping frame 71, and a first clamping belt 72, a second clamping belt 73, a first motor for driving the first clamping belt 72 to rotate, and a second motor for driving the second clamping belt 73 to rotate are installed on the clamping frame 71. A clamping channel for clamping ramie is provided between the first clamping belt 72 and the second clamping belt 73 to form a clamping belt group, and the spacing between the clamping belt group and the conveying belt 32 gradually decreases backwards. When working, the conveying speed of the clamping belt group is lower than the conveying speed of the conveying belt 32.

[0035] Through the above scheme, the ramie is stretched and tilted by the speed difference of conveying, ensuring that the ramie can be smoothly conveyed to the stripping device 6. The speed difference can also be adjusted to select the upper end or the lower end of the ramie to enter the stripping device 6 first, and the adjustment can be made according to the variety, quality or harvesting environment of the ramie to obtain a better stripping effect.

[0036] As a specific implementation method of the improvement, refer to Figure 1 As shown, there are several clamping mechanisms 7, and a guiding mechanism 8 is installed at the front end of the conveying frame 31.

A first guide plate 83 is fixedly connected to the first support rod 81, and a second guide plate 84 is fixedly connected to the second support rod 82. Rotating support wheels 74 are provided inside the opposite sides of the first clamping belt 72 and the second clamping belt 73.

[0037] Through the above scheme, the ramie stems are guided to enter the clamping channel, and the rotating support wheel 85 can provide support to the clamping belt to ensure smooth transportation.

[0038] As a specific implementation method of the improvement, refer to Figure 1 As shown, the driving device 2 includes a chassis 21, on which a driving mechanism, a first track group 22 and a second track group 23 are installed. The driving mechanism is used to drive the first track group 22 and the second track group 23 to rotate. A differential is installed in the driving mechanism. The differential is used to form a speed difference between the first track group 22 and the second track group 23. The driving mechanism and the differential are both electrically connected to the control console 11.

[0039] Through the above scheme, the crawler movement can adapt to most agricultural terrains.

[0040] As a specific implementation method of the improvement, refer to Figure 4 As shown, the harvesting device 5 includes a harvesting bracket 51, on which a harvesting motor 52 is installed, and an output end of the harvesting motor 52 is connected to a harvesting blade 53. The harvesting bracket 51 is rotatably connected to the conveying frame 31, and an electric telescopic rod 54 is installed on the conveying frame 31. The front end of the electric telescopic rod 54 is rotatably connected to the harvesting bracket 51 to drive the harvesting bracket 51 to rotate relative to the conveying frame 31.

[0041] Through the above solution, the electric telescopic rod 54 is electrically connected to the control console 11, and can be controlled to extend and retract to adjust the cutting angle and the harvesting height in a small range.
