Technical Field

[0001] The utility model relates to the technical field of harvesters, in particular to a Strobilanthes cusia harvester with adjustable cutting speed. Background Technique

[0002] Strobilanthes cusia is a perennial herbaceous crop. Its rhizome has creeping branches, and its stem is erect, with a height of up to 70 - 90 cm. After maturity, it becomes severely lignified. During harvesting, it needs to be fully cut. If the cutting is incomplete, it will cause slow growth in the next season. At this time, a Strobilanthes cusia harvester is needed to harvest Strobilanthes cusia. According to the planting row spacing of Strobilanthes cusia, the wheelbase for harvesting Strobilanthes cusia is controlled between 30 - 40 cm, and the cutting width is controlled within 90 cm, ensuring that the machine will not crush the roots of Strobilanthes cusia during walking and can harvest two rows of Strobilanthes cusia at one time.

[0003] Generally, the Strobilanthes cusia harvester runs with a single diesel gearbox, with a slow rotation speed, and the walking speed is proportional to the cutting speed. This causes incomplete cutting and large cutting damage to severely lignified Strobilanthes cusia during the cutting process of the Strobilanthes cusia harvester. Moreover, the height of the cutting table of the general Strobilanthes cusia harvester is fixed, making it difficult to adjust the stubble height. Therefore, we propose a Strobilanthes cusia harvester with adjustable cutting speed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a Strobilanthes cusia harvester with adjustable cutting speed to solve the problems in the above background technique that the walking speed of the general Strobilanthes cusia harvester is proportional to the cutting speed, resulting in incomplete cutting and large cutting damage to severely lignified Strobilanthes cusia during the cutting process, and it is difficult to adjust the stubble height.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A Strobilanthes cusia harvester with adjustable cutting speed, including a harvester main body. A bottom plate is fixed to the lower side of the harvester main body, and a cutting table is arranged on one side of the bottom plate. A driving motor and a gearbox are sequentially installed on the upper side of the cutting table. A connecting plate is fixed to one side of the cutting table, and push plates that are matched through inclined surfaces are also arranged at both ends of the connecting plate.

A first screw rod penetrates through the interiors of the two sliders, and the first screw rod is rotationally supported in the sliding groove through a bearing.

[0006] Preferably, a first gear disk is fixed to one end of the first screw rod, and the first screw rod is also connected to a connecting motor that drives its rotation. The connecting motor is installed on the bottom plate.

[0007] Preferably, it further includes a second toothed disc. A toothed belt is wound around the first toothed disc and the second toothed disc together. A first bevel gear is also installed on the central rod of the second toothed disc. The first bevel gear meshes with a second bevel gear, and a second screw rod is installed on the central rod of the second bevel gear.

[0008] Preferably, the first toothed disc, the second toothed disc, the first bevel gear, the second bevel gear, and the second screw rod are respectively rotatably installed on the bottom plate through bearings.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1 - 4, the present utility model provides a technical solution: an indigo harvester with adjustable cutting speed, which includes a harvester main body 1. A bottom plate 101 is fixed to the lower side of the harvester main body 1, and a cutting table 102 is arranged on one side of the bottom plate 101. A driving motor 103 and a gearbox 104 are sequentially installed on the upper side of the cutting table 102. A connecting plate 2 is fixed to one side of the cutting table 102. Push plates 201 that are matched through inclined surfaces are further provided at both ends of the connecting plate 2. A slider 2011 is fixed to the lower side of the push plate 201. A chute 202 is opened on one side of the bottom plate 101 close to the slider 2011, and the slider 2011 is slidably butted with the chute 202. A first screw rod 203 penetrates through the inside of the two sliders 2011. The first screw rod 203 is rotationally supported in the chute 202 through a bearing. A first gear disk 204 is fixed to one end of the first screw rod 203. The first screw rod 203 is further connected with a connecting motor 205 for driving its rotation, and the connecting motor 205 is installed on the bottom plate 101; it further includes a second gear disk 206. A toothed belt 2041 is wound around the first gear disk 204 and the second gear disk 206 together. A first bevel gear 207 is further installed on the central rod of the second gear disk 206. The first bevel gear 207 meshes with a second bevel gear 208. A second screw rod 209 is installed on the central rod of the second bevel gear 208. The first gear disk 204, the second gear disk 206, the first bevel gear 207, the second bevel gear 208 and the second screw rod 209 are respectively rotationally installed on the bottom plate 101 through bearings; A docking pipe 210 with a threaded fit is sleeved on the second screw rod 209. A connecting block 211 is fixed to the outer wall of the docking pipe 210. A sliding rod 212 slidably penetrates through the inside of the connecting block 211. The lower end of the sliding rod 212 is fixed to the bottom plate 101. The upper end of the docking pipe 210 is bolted with a fixing plate 213 for pressing the connecting plate 2. The slider 2011 matches the chute 202. The slider 2011 is in threaded fit with the first screw rod 203, and the thread directions at both ends of the first screw rod 203 are in opposite directions. The first gear disk 204 and the second gear disk 206 are in meshing connection with the toothed belt 2041. The first bevel gear 207 is in meshing connection with the second bevel gear 208. The second screw rod 209 is in threaded connection with the docking pipe 210.

[0020] During specific implementation, according to Figures 1 - 4, when the Strobilanthes cusia harvester harvests Strobilanthes cusia, rotate the bolt to remove the fixing plate 213 from the upper end of the docking pipe 210. Place the connecting plate 2 between the two push plates 201, and make the inclined surface of the connecting plate 2 fit with the inclined surface of the push plate 201. At this time, use the bolt again to limit the fixing plate 213 and the docking pipe 210 together, and make the upper side of the fixing plate 213 fit with the connecting plate 2, so that the connecting plate 2 is restricted between the two push plates 201 and the fixing plate 213, and the cutting table 102 is restricted on one side of the harvester main body 1. At this time, start the connecting motor 205, and make the output end of the connecting motor 205 drive the first screw rod 203 and the first gear disk 204 to rotate simultaneously. When the first gear disk 204 rotates, through the meshing connection of the first gear disk 204 and the second gear disk 206 with the toothed belt 2041, the first gear disk 204 drives the second gear disk 206 to rotate through the toothed belt 2041, so that the second gear disk 206 can drive the first bevel gear 207 to rotate. Then, through the meshing connection of the first bevel gear 207 and the second bevel gear 208, the first bevel gear 207 drives the second bevel gear 208 to rotate, and the second bevel gear 208 drives the second screw rod 209 to rotate. At this time, through the sliding penetration of the connecting block 211 and the sliding rod 212, the sliding rod 212 can prevent the docking pipe 210 from rotating with the second screw rod 209 through the connecting block 211. At this time, the first screw rod 203 and the second screw rod 209 rotate simultaneously. When the first screw rod 203 rotates, through the matching of the slider 2011 and the chute 202, the slider 2011 will not rotate with the first screw rod 203. Then, through the threaded connection of the slider 2011 and the first screw rod 203, and the thread directions at both ends of the first screw rod 203 are opposite, the two sliders 2011 can approach each other, and the slider 2011 drives the push plate 201 to squeeze the inclined surface of the connecting plate 2, so that the connecting plate 2 has the power to move upward. At the same time, when the second screw rod 209 rotates, through the threaded connection of the second screw rod 209 and the docking pipe 210, the docking pipe 210 drives the connecting block 211 to move upward along the sliding rod 212, and the docking pipe 210 stably drives the fixing plate 213 to move upward. At this time, the push plate 201 squeezes the inclined surface of the connecting plate 2. When the connecting plate 2 moves upward, the fixing plate 213 moves upward while fitting with the upper side of the connecting plate 2, so that the connecting plate 2 can stably drive the cutting table 102 to move upward, making the Strobilanthes cusia harvester easy to adjust the stubble height. And at this time, start the driving motor 103, and the driving motor 103 drives the blade of the cutting table 102 to rotate through the gearbox 104, so that the cutting table 102 can control its own cutting speed, and the harvester main body 1 can control its own traveling speed, making the Strobilanthes cusia harvester able to control the cutting speed and the traveling speed respectively, so that the Strobilanthes cusia harvester is convenient to fully cut and harvest Strobilanthes cusia.

[0021] In summary, when the Strobilanthes cusia harvester harvests Strobilanthes cusia, the cutting table 102 is restricted to one side of the harvester main body 1. At this time, the connecting motor 205 is started, so that the connecting plate 2 can stably drive the cutting table 102 to move upward, making it convenient for the Strobilanthes cusia harvester to adjust the stubble height. And at this time, the driving motor 103 is started, and the driving motor 103 drives the blades of the cutting table 102 to rotate through the gearbox 104, so that the cutting table 102 can control the cutting speed by itself, and the harvester main body 1 can control the traveling speed by itself, enabling the Strobilanthes cusia harvester to control the cutting speed and the traveling speed separately, making it convenient for the Strobilanthes cusia harvester to fully cut and harvest Strobilanthes cusia.
