DETAILED DESCRIPTION

[0021] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. The same parts are represented by the same reference numerals. 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 threshing and collecting device of the ramie harvester includes a frame 1, on which is mounted a control console 11, a conveying device 2 for conveying ramie and a storage box 3 for storing ramie, a stripping device 4 for threshing ramie is mounted at the box opening of the storage box 3, the stripping device 4 is connected to the conveying device 2 and is mounted at the rear end of the conveying device 2, the stripping device 4 includes a stripping tube cover 41 fixedly connected to the storage box 3, a coarse stripping roller group 42, a fine stripping roller group 43 and an adjusting roller 44 are mounted in the stripping tube cover 41, the adjusting roller 44 is mounted between the coarse stripping roller group 42 and the fine stripping roller group 43, and floating mechanisms 45 are mounted at both ends of the adjusting roller 44.

[0023] Through the above scheme, the conveying device 2 conveys the ramie to the stripping device 4, the stripping device 4 strips the ramie and puts the stripped ramie into the storage box 3 for storage. When stripping the ramie, the coarse stripping roller group 42 first strips the ramie roughly to crush and separate the ramie tissue, and the fine stripping roller group 43 further strips the ramie to separate the ramie fibers. The adjusting roller 44 is arranged between the coarse stripping roller group 42 and the fine stripping roller group 43. The floating mechanism 45 enables the adjusting roller 44 to elastically squeeze the ramie, stably stretch the ramie during stripping, keep the ramie fibers straight and elongated, avoid deformation, ensure the stripping quality, ensure the stripping effect, and improve the quality of the ramie after stripping.

[0024] As an improved specific embodiment, the floating mechanism 45 includes a mounting plate 451, the mounting plate 451 is provided with a floating hole 452, a floating block 453 and a slide groove 456 are provided in the floating hole 452, a plurality of floating springs 454 and two slide holes 457 are connected around the floating block 453, a slide rod 458 is passed through the two slide holes 457, the slide rod 457 is slidably connected to the slide groove 456, one end of the plurality of floating springs 454 are connected to the inner wall of the floating hole 452, and a limiting ring 455 for limiting the plurality of floating springs 454 is also installed at the orifice of the floating hole 452.

[0025] Through the above scheme, the two ends of the adjusting roller 44 are respectively rotatably connected to the corresponding floating block 453, so that the adjusting roller 44 can elastically contact the ramie, and the elastic force can be limited to a certain range as much as possible regardless of the speed and quantity of ramie stripping, so that the ramie fiber will not break, can be stably stretched, and maintain the smooth operation of the stripping action. The sliding hole 457 cooperates with the sliding rod 458 to enable the floating block 453 to slide up and down, and the sliding rod 457 cooperates with the sliding groove 456 to enable the floating block 453 to slide left and right, so that the floating block 453 can move freely within a certain range.

[0026] As an improved specific implementation method, the rough stripping roller group 42 includes a first rough stripping roller 421 and a second rough stripping roller 422, the first rough stripping roller 421 is arranged above the second rough stripping roller 422, and the first rough stripping roller 421 and the second rough stripping roller 422 are both provided with a plurality of rough stripping protrusions 423 with a trapezoidal cross-section, and both ends of the first rough stripping roller 421 are also rotatably connected to swing arms 424, and the two swing arms 424 are both provided with rotating blocks 425 and counterweights 426, and the two rotating blocks 425 are respectively rotatably connected to the inner walls on both sides of the stripping tube cover 41, and the inner walls on both sides of the stripping tube cover 41 are also installed with electric telescopic rods 46, and the two electric telescopic rods 46 are both installed with push rods 461, and the two push rods 461 are respectively arranged below the corresponding counterweights 426.

[0027] Through the above scheme, the first rough stripping roller 421 is pressed down with the counterweight block 426 and its own weight, which can achieve a better effect of squeezing and crushing ramie, so that the ramie fibers are separated from other fibers, and can achieve a flexible squeezing effect to avoid the breakage of the ramie fibers. The second rough stripping roller 422 rotates to drive the first rough stripping roller 421 to rotate through the contact between the rough stripping protrusions 423 of the two, and give a better effect of squeezing ramie. The electric telescopic rod 46 can adjust the height of the top rod 461, thereby limiting the position of the first rough stripping roller 421, thereby adjusting the gap distance between the first rough stripping roller 421 and the second rough stripping roller 422. The trapezoidal structure can reduce the gap and fully contact the ramie rod.

[0028] As an improved specific implementation method, the fine stripping roller group 43 includes a small stripping roller 431 and a large stripping roller 432. The small stripping roller 431 is arranged behind the adjusting roller 44 and is arranged obliquely above and in front of the large stripping roller 432. The adjusting roller 44, the small stripping roller 431 and the large stripping roller 432 are all provided with fine stripping blades 433 of different sizes.

[0029] Through the above scheme, the fine stripping blades 433 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. The different sizes of the rollers can make the scraping speed and angle different, so that the ramie fibers can be better separated.

[0030] As an improved specific implementation, an arc-shaped protrusion 411 is provided on the stripping tube cover 41 , and the arc-shaped protrusion 411 forms an accommodating cavity for accommodating part of the stripping roller 431 .

[0031] Through the above scheme, the space is expanded, the adjustment of the installation position is convenient, and the ramie fiber is convenient to change the moving route and be fully stretched, squeezed and peeled.

[0032] As an improved specific implementation, a swing motor 5 is installed at the rear end of the stripping tube cover 41, and a swing rod 51 that swings backward and left and right is installed on the output shaft of the swing motor 5.

[0033] Through the above scheme, the stripped ramie is beaten by the swing rod 51, so that the ramie fibers are spread out and fully separated. And through the swinging action, the ramie can be dispersed and stacked in the storage box 3 to avoid the problem of single-point stacking. The swing rod 51 is tilted downward to facilitate the limited dispersion of the ramie.

[0034] As an improved specific implementation, a hair dryer 6 blowing obliquely rearward is installed below the rear end of the stripping tube cover 41 of the material storage box 3, and a protective grille 61 inclined rearward and downward is also installed above the air outlet of the hair dryer 6.

[0035] Through the above scheme, ramie fibers and other stripped debris fall onto the protective grille 61, and the blower 6 blows the debris out of the storage box 3 from the box opening, while the stripped ramie fibers fall into the storage box 3 under their own weight. The protective grille 61 is tilted downward to prevent ramie fibers from accumulating. The swing rod 51 is arranged above the protective grille 61, and can break up and separate the ramie fibers accumulated on the protective grille 61.

[0036] As an improved specific embodiment, the conveying device 2 includes a conveying frame 21, which is rotatably connected to the stripping tube cover 41. The conveying frame 21 is equipped with a conveyor belt 22 and a clamping mechanism 7. The clamping mechanism 7 includes a clamping frame 71, and the clamping frame 71 is equipped with a first clamping belt 72 and a second clamping belt 73. 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. The spacing between the clamping belt group and the conveyor belt 22 gradually decreases backward. When working, the conveying speed of the clamping belt group is lower than the conveying speed of the conveyor belt 22.

[0037] 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 4. The speed difference can also be adjusted to select the upper end or the lower end of the ramie to enter the stripping device 4 first, and the adjustment can be made according to the variety, quality or harvesting environment of the ramie to obtain a better stripping effect.

[0038] As an improved specific embodiment, a stacking mechanism 8 is also installed on the rear end of the clamping frame 71, and the stacking mechanism 8 includes a rotating roller 81. The upper end of the rotating roller 81 is rotatably connected to the clamping frame 71, and a beating plate 82 is installed on the rotating roller 81. The upper end of the rotating roller 82 is connected to a rotating arm 83.

[0039] Through the above solution, the rotating roller 23 rotates to drive the beating plate 231 to beat and disperse the ramie to avoid it from being concentrated into the beating and stripping device 4.

[0040] As an improved specific implementation, a plurality of conveying plates 24 are equidistantly arranged on the conveying belt 22 .

[0041] Through the above solution, the conveying plate 24 can contact and drive the ramie more effectively.

[0042] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
