Detailed Implementation

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "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 harvester's stripping and collecting device includes a frame 1, on which a control console 11, a conveying device 2 for conveying ramie, and a storage bin 3 for storing ramie are mounted. A stripping device 4 for stripping ramie is installed at the opening of the storage bin 3. The stripping device 4 is connected to the conveying device 2 and is installed at the rear end of the conveying device 2. The stripping device 4 includes a stripping tube cover 41 fixedly connected to the storage bin 3. A coarse stripping roller group 42, a fine stripping roller group 43, and an adjusting roller 44 are installed inside the stripping tube cover 41. The adjusting roller 44 is installed between the coarse stripping roller group 42 and the fine stripping roller group 43. A floating mechanism 45 is installed at both ends of the adjusting roller 44.

[0023] Through the above scheme, the conveying device 2 transports ramie to the stripping device 4, which strips the ramie and places the stripped ramie into the storage bin 3. During the stripping process, the coarse stripping roller group 42 first performs preliminary coarse stripping of the ramie, breaking and separating the ramie structure. The fine stripping roller group 43 then further strips the ramie, separating the ramie fibers. The adjusting roller 44 is positioned between the coarse stripping roller group 42 and the fine stripping roller group 43. The floating mechanism 45 allows the adjusting roller 44 to elastically squeeze and tighten the ramie, stably stretching the ramie during stripping, keeping the ramie fibers straight and elongated, avoiding deformation, ensuring stripping quality, ensuring stripping effect, and improving the quality of the stripped ramie.

[0024] As an improved specific implementation, 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 sliding groove 456 are provided in the floating hole 452, a plurality of floating springs 454 and two sliding holes 457 are connected around the floating block 453, a sliding rod 458 is passed through the two sliding holes 457, the sliding rod 458 is slidably connected to the sliding groove 456, one end of each of the plurality of floating springs 454 is 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 opening of the floating hole 452.

[0025] With the above scheme, the two ends of the adjusting roller 44 are rotatably connected to the corresponding floating blocks 453, allowing the adjusting roller 44 to elastically contact the ramie. Regardless of the speed or quantity of ramie beating, the elasticity can be limited to a certain range as much as possible, thus preventing the ramie fibers from breaking and allowing for stable stretching, maintaining the smooth operation of the beating action. The sliding hole 457 cooperates with the sliding rod 458 to allow the floating block 453 to slide up and down, and the sliding rod 458 cooperates with the sliding groove 456 to allow the floating block 453 to slide left and right, thus enabling the floating block 453 to move freely within a certain range.

[0026] As an improved specific implementation, the coarse stripping roller assembly 42 includes a first coarse stripping roller 421 and a second coarse stripping roller 422. The first coarse stripping roller 421 is disposed above the second coarse stripping roller 422. Both the first coarse stripping roller 421 and the second coarse stripping roller 422 are provided with a plurality of coarse stripping protrusions 423 with trapezoidal cross sections. Both ends of the first coarse stripping roller 421 are rotatably connected to swing arms 424. Both swing arms 424 are provided with rotating blocks 425 and counterweights 426. The two rotating blocks 425 are respectively rotatably connected to the inner walls of both sides of the stripping tube cover 41. Both sides of the inner walls of the stripping tube cover 41 are also equipped with electric telescopic rods 46. Both electric telescopic rods 46 are equipped with top rods 461. The two top rods 461 are respectively disposed below the corresponding counterweights 426.

[0027] Through the above scheme, the first coarse stripping roller 421, driven by the counterweight 426 and its own weight, presses down, achieving a better effect of crushing and separating ramie fibers, thus separating the ramie fibers from others. It also provides a flexible compression effect, preventing the ramie fibers from breaking. The rotation of the second coarse stripping roller 422, through the contact between the coarse stripping protrusions 423 of both rollers, drives the first coarse stripping roller 421 to rotate, providing an even better crushing effect on the ramie. The electric telescopic rod 46 can adjust the height of the top rod 461, thereby limiting the position of the first coarse stripping roller 421 and adjusting the gap between the first and second coarse stripping rollers 421 and 422. The trapezoidal structure reduces the gap and ensures full contact with the ramie stalks.

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

[0029] Through the above method, the fine stripping blades 433 can scrape the broken fibers and bark from the ramie fibers, and even remove the leaves from the ramie stalks, thus allowing the ramie fibers to be fully separated. Different roller sizes allow for varying scraping speeds and angles, resulting in even better separation of the ramie fibers.

[0030] As an improved specific implementation, the peeling tube cover 41 is provided with an arc-shaped protrusion 411, which forms a receiving cavity for accommodating part of the peeling roller 431.

[0031] The above solution expands the space, facilitates the adjustment of the installation position, and allows the ramie fibers to change their movement path, being fully stretched, squeezed, and peeled.

[0032] As one specific implementation of the improvement, 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 method, the ramie fibers are beaten by the swing rod 51, causing them to disperse and be fully separated. Furthermore, the swinging motion allows the ramie fibers to be dispersed and piled in the storage bin 3, avoiding the problem of single-point stacking. The swing rod 51 is tilted downwards to facilitate the dispersion of the ramie fibers.

[0034] As one specific implementation of the improvement, the storage bin 3 is equipped with a blower 6 that blows air at an angle to the rear below the rear end of the stripping tube cover 41, and a protective grille 61 that tilts downwards and backwards is also installed above the air outlet of the blower 6.

[0035] Through the above method, ramie fibers and other stripped debris fall onto the protective grid 61. The blower 6 blows the debris out of the storage bin 3, while the stripped ramie fibers fall into the storage bin 3 under their own weight. The protective grid 61 is tilted downwards to prevent ramie fibers from accumulating. The swing rod 51 is positioned above the protective grid 61 to disperse and separate the ramie fibers accumulated on it.

[0036] As an improved specific implementation, 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, on which a first clamping belt 72 and a second clamping belt 73 are installed. 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 distance between the clamping belt group and the conveyor belt 22 gradually decreases backward. During operation, the conveying speed of the clamping belt group is less than the conveying speed of the conveyor belt 22.

[0037] The above method utilizes the speed difference during transport to stretch and tilt the ramie fibers, ensuring they are smoothly conveyed into the stripping device 4. The speed difference can also be adjusted to allow either the upper or lower end of the ramie fibers to enter the stripping device 4 first, depending on the variety, quality, or harvesting environment of the ramie fibers, to achieve better stripping results.

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

[0039] Through the above scheme, the rotating roller 81 rotates and drives the beating plate 82 to beat and disperse the ramie, preventing it from being concentrated in the beating and peeling device 4.

[0040] As one specific implementation of the improvement, multiple conveyor plates 24 are equidistantly arranged on the conveyor belt 22.

[0041] Through the above scheme, the conveyor plate 24 can more effectively contact and move the ramie.

[0042] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
