[0030] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0031] Example:

[0032] like Figures 1-6 As shown, a self-propelled ramie stripping machine includes a frame 100, a transmission mechanism, and a disconnection mechanism; the bottom of opposite sides of the frame 100 is provided with a drive wheel 110 and a driven wheel 120 respectively; the top of the frame 100 is provided with a stripping device 200 for ramie crops and a power unit 300 that provides power to the drive wheel 110 and the stripping device 200.

[0033] The peeling device 200 includes a frame, peeling rollers, a cover 230, and a linkage mechanism. The frame includes a vertical frame 211, an intermediate frame 212, and a top frame 213. Two vertical frames 211, one higher and one lower, are respectively located on the top sides of the frame 100. The intermediate frame 212 is located in the middle between the two vertical frames 211. The top frame 213 connects to the tops of the two vertical frames 211 on both sides, thus tilting the top frame 213. The peeling roller includes a main roller 221 and a secondary roller 222. The lower side of the top frame 213 has two vertical rollers on its top sides. The main roller 221 is provided with a bearing seat for rotatably connecting to it; the intermediate frame 212 is located on the bottom of the higher side of the top frame 213 and is provided with bearing seats for rotatably connecting to the driven roller 222 on both sides; the linkage mechanism is located on the same side of the main roller 221 and the driven roller 222, and can be two meshing gears, and a dust cover can be provided on the outside of the linkage mechanism; the machine cover 230 is located on the top of the top frame 213, and the machine cover 230 is provided with an inlet 231 inclined towards the space between the main roller 221 and the driven roller 222 on the higher side of the top frame 213;

[0034] The transmission mechanism includes a first transmission component, a second transmission component, and a third transmission component. The first transmission component includes a first pulley 411, a second pulley 412, an intermediate housing 413, and a first belt. The second transmission component includes a universal joint drive shaft 421 and a drive axle 422. The third transmission component includes a third pulley 430 and a second belt. The power unit 300 can be a diesel engine. The first pulley 411 is connected to the output shaft of the power unit 300. The intermediate housing 413 is located on the bottom side of the middle of the frame 100. The second pulley... 412 is located on the shaft of the intermediate box 413 facing the power unit 300. The second pulley 412 is connected to the first pulley 411 via the first belt. The drive axle 422 is located at the bottom of the frame 100 and is connected to the drive wheels 110 at both ends. The side of the intermediate box 413 facing away from the second pulley 412 is driven and connected to the drive axle 422 via the universal joint drive shaft 421. The third pulley 430 is located at the end of the main roller 221 near the power unit 300 and is connected to the second pulley 412 via the second belt.

[0035] The disconnection mechanism includes a first disconnection component and a second disconnection component. The first disconnection component includes a clutch and a control lever 510. The clutch is located between the intermediate housing 413 and the universal joint drive shaft 421. The control lever 510 is located on the frame 100 and connected to the clutch, used to operate the clutch to disconnect or connect the transmission of the intermediate housing 413 and the universal joint drive shaft 421. The second disconnection component includes a first movable seat 521 and a tensioning wheel 522. The first movable seat 521 is movably mounted on the intermediate frame 212. The stripping device 200 is provided with a locking structure for the first movable seat 521. A strip hole is provided on the top side of the intermediate frame 212 along the radial direction of the tensioning wheel 522. The first movable seat 521 is locked in position by bolts passing through the strip hole and the first movable seat 521 as a locking structure. The tensioning wheel 522 is rotatably mounted on the first movable seat 521. One side of the tensioning wheel 522 is pressed against the slack side of the second belt to achieve tension.

[0036] The working principle of the above technical solution is as follows:

[0037] When in use, the power unit 300 is started, and the power unit 300 rotates the first pulley 411, which drives the second pulley 412 on the intermediate box 413 to rotate through the first belt. The rotation of the second pulley 412 drives the universal joint drive shaft 421 through the intermediate box 413, which drives the drive wheel 110 to rotate through the drive axle 422. This, together with the driven wheel 120, enables the movement of the stripping machine. At the same time, the second pulley 412 drives the third pulley 430 to rotate through the second belt, and the main drum 221 rotates. Through the linkage mechanism, the driven drum 222 rotates, so that the drive wheel 110 and the stripping device 200 can operate simultaneously. Hemp crops are put into the feed port 231, so that the hemp crops slide between the main drum 221 and the driven drum 222 for stripping operation.

[0038] When only walking is required, the locking of the first movable seat 521 can be released, and the position of the tension wheel 522 can be moved so that the tension wheel 522 no longer contacts the second belt. After the second belt loosens, it can be removed, disconnecting the power transmission between the second pulley 412 and the third pulley 430. When only stripping operation is required, the clutch can be operated by the control lever 510 to disconnect the transmission between the intermediate box 413 and the universal joint drive shaft 421, thereby stopping the rotation of the drive wheel 110. The clutch here is preferably a jaw clutch. The specific structure of the control lever 510 and the principle of the clutch are existing technologies and will not be described in detail here. The above structure realizes multiple operating modes through a single power source, reducing power waste and facilitating use.

[0039] In another embodiment, such as Figure 3As shown, the bearing seats at both ends of the roller 222 serve as the second movable seats 223. The intermediate frame 212 is provided with corresponding strip holes for the second movable seats 223. The locking method of the second movable seats 223 is the same as that of the first movable seat 521, which is to achieve locking by bolts passing through themselves and the corresponding strip holes. The difference from the above is that the linkage mechanism may include a fourth pulley and a fifth pulley, which are respectively connected to the ends of the main roller 221 and the driven roller 222. A third belt is provided between the fourth pulley and the fifth pulley.

[0040] The second movable seat 223 is horizontally adjusted along the intermediate frame 212 and locked by bolts, thereby adjusting the distance between the roller 222 and the main roller 221 to accommodate the stripping of different varieties of hemp fibers.

[0041] In another embodiment, such as Figure 5 As shown, the frame 100 is provided with an adjustment structure 600 for the power unit 300, including a movable frame 610, a rail 620, an adjustment seat 630, an adjustment screw, and a handle 640; the movable frame 610 is located at the bottom of the power unit 300 and is slidably connected to the rail 620; the adjustment seat 630 is located at one end of the rail 620, and a nut adapted to the adjustment screw is provided in the middle of the adjustment seat 630. The adjustment screw passes through the nut and is rotatably connected to the movable frame 610, and the handle 640 is located at the end of the adjustment screw.

[0042] Rotating the handle 640 can push the movable frame 610 to move horizontally on the track 620 by adjusting the screw, thereby adjusting the position of the power unit 300, facilitating belt replacement, and making it easy to adjust the belt tension.

[0043] In another embodiment, such as Figure 1 , Figure 2 and Figure 6 As shown, one driven wheel 120 is preferred, serving as a steering wheel, and is located at the middle of the bottom of the frame 100 on the side away from the drive wheel 110; handrails 130 are also provided on both sides of the side of the frame 100 away from the drive wheel 110; the frame 100 is provided with brake structures 140 for the two drive wheels 110 respectively, and the brake structures 140 can be any suitable structure selected from the prior art, and this embodiment does not impose any restrictions.

[0044] The drive wheel 110 of the peeling machine runs at low speed and is moved by the operator holding the handle 130. The rotation of the drive wheel 110 to the left and right is controlled by the brake structure 140, which works in conjunction with the driven wheel 120 for differential steering.

[0045] In another embodiment, such as Figure 1-2 As shown, a collection box 700 is provided on the top of the frame 100.

[0046] The collection box 700 is used to collect the stripped fibers, which increases the amount of fiber transferred and reduces labor input.

[0047] The embodiments described above are merely illustrative of specific implementations of the present invention, and while the descriptions are detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
