[0002] Tobacco is an important cash crop, and tobacco leaves need intensive cultivation throughout the process from planting to harvesting. Tobacco leaves can basically reach the picking requirement after 5 - 6 months of planting and need to be picked within 2 months. There are about 13 - 15 effective leaves on one tobacco plant. At the same time, since the leaves on the tobacco plant do not mature simultaneously, according to the growth position of the tobacco leaves, they are divided into upper leaves, middle leaves, and bottom leaves. Among them, the bottom leaves are the first to mature, followed by the middle leaves, and finally the upper leaves. The time interval between the maturity of the upper leaves and the bottom leaves is about 1 month, and the maturity time span is relatively long.

[0003] Currently, all existing tobacco leaf picking machines harvest all the leaves on one tobacco plant at once. According to the requirements of tobacco leaf maturity, currently, tobacco leaves are picked manually, which requires a large amount of manpower and material resources. At the same time, the serious shortage of rural labor also restricts the scale of tobacco leaf planting. Summary of the Invention

[0035] Embodiment 1:

[0036] Refer to Figure 1 - Figure 7, which is an embodiment of the present invention, provides a tobacco leaf picking and conveying device, including a mobile support unit 100, a conveying and transporting unit 200, and a lifting and cutting unit 300.

[0037] Among them, the mobile support unit 100 includes a carrying frame 101 and a machine base fixedly connected inside the carrying frame 101. A driving motor 110 is fixedly connected to the upper surface of the machine base. Discharge slots 112 are opened on both sides of the carrying frame 101, and collection frames 104 are fixedly connected to both sides of the carrying frame 101;

[0038] Secondly, the conveying and transporting unit 200 includes a conveyor belt 202 rotatably connected in the discharge slot 112 through a rotating rod and a first guide rail 204 fixedly connected to the inner wall of the carrying frame 101. The conveyor belt 202 is L-shaped. The rotating rods inside the conveyor belt 202 are fixedly connected through connecting blocks 201 and connecting plates 213. A second guide rail 206 is fixedly connected inside the carrying frame 101;

[0039] Finally, the lifting and cutting unit 300 includes a moving block arranged in the first guide rail 204 and a carrying rod 214 fixedly connected to one side of the moving block. A load-bearing plate 312 is fixedly connected to the upper surface of the carrying rod 214. An electric push rod is arranged inside the load-bearing plate 312. The electric push rod is fixedly connected to a connecting rod 314 on the side away from the load-bearing plate 312. Fixed plates 301 are fixedly connected to both sides of the upper surface of the connecting rod 314. One end of the telescopic shaft of the electric push rod is fixedly connected to a spring rod 310.

[0040] Furthermore, the number of driving motors 110 is several, and several driving motors 110 are evenly symmetrically distributed with respect to the carrying frame 101. One end of the output shaft of the driving motor 110 is rotatably connected to a belt 108. U-shaped plates 102 are fixedly connected to both sides of the carrying frame 101. Protective plates 105 are fixedly connected to both sides of the carrying frame 101. The protective plates 105 are U-shaped structures. Guide rods 103 are fixedly connected to both sides of the carrying frame 101. Among them, the driving wheels 106 are rolled synchronously by multiple groups of symmetrically distributed driving motors 110, so that the entire carrying frame 101 moves through the rolling of the driving wheels 106.

[0041] Further, one side of the collection box 104 is snap-connected inside the guiding rod 103. A driving shaft 111 is rotatably connected inside the bearing box 101. A driving wheel 106 is fixedly connected to the outer surface of the driving shaft 111. A fixing ring 109 is fixedly connected to the outer surface of the driving shaft 111. A belt 108 is rotatably connected to the outer surface of the fixing ring 109. A driving groove is formed inside the bearing box 101, and the belt 108 is arranged inside the driving groove. One side of the bearing box 101 is fixedly connected with an inclined plate 107. Among them, through multiple driving shafts 111 that are matched with the driving motor 110, the driving wheel 106 as a whole is fully driven to rotate. Further, the inclined plate 107 is used to block the conveyed tobacco leaves to prevent their speed from being too high, which may cause the tobacco leaves to fall off easily during the harvesting process of the equipment.

[0042] Further, a plurality of equally spaced and symmetrically distributed adjusting motors 207 are fixedly connected to the upper surface inside the bearing box 101. One end of the output shaft of the adjusting motor 207 is fixedly connected with a first adjusting shaft 212 and a second adjusting shaft 211. The outer surfaces of the first adjusting shaft 212 and the second adjusting shaft 211 are both threadedly connected inside the moving block. Among them, the positions of the moving blocks are adjusted by a plurality of adjusting motors 207, so that the internal structure of the equipment rises and falls, and thus the tobacco leaves at a certain height can be cut during the forward movement.

[0043] Further, the second guide rail 206 is fixedly connected with a lifting plate 203 through the moving block. Fixing blocks 210 are fixedly connected to both sides of the lifting plate 203. A connecting rod 208 is fixedly connected to the lower surface of the fixing block 210. A limiting plate 215 is fixedly connected to the lower surface of the connecting rod 208. The upper surface of the connecting block 201 is fixedly connected to the lower surface of the limiting plate 215. A pulling rod 209 is fixedly connected to the upper surface of the limiting plate 215. A slide rail 205 is fixedly connected to the inner surface of the bearing box 101, and one end of the pulling rod 209 is slidably connected inside the slide rail 205. Among them, by using a plurality of slidable tracks, the internal structure of the equipment can be lifted and lowered more smoothly to a certain extent.

[0044] Working principle: By using the driving wheel 106, the inclined plate 107, the belt 108, the fixing ring 109, the driving motor 110 and the driving shaft 111, the driving motor 110 drives the driving wheel 106 to roll on the ground, so that the whole equipment can move quickly. Further, by using the symmetrical structure design of the bearing box 101, the conveying and transporting unit 200 and the lifting and cutting unit 300 can rise and fall simultaneously, and thus the tobacco leaves at a certain height can be cut and collected quickly;

[0045] Utilize the conveyor belt 202, lifting plate 203, first guide rail 204, slide rail 205, second guide rail 206, adjustment motor 207, connecting rod 208, pulling rod 209, fixed block 210, second adjustment shaft 211 and first adjustment shaft 212 to enable the conveyor belt 202 to perform overall collection and processing on the tobacco leaves cut by the lifting and cutting unit 300. Further, utilize the adjustment motor 207 to drive the moving blocks inside the first guide rail 204 and the second guide rail 206 respectively, so that the conveyor belt 202 and the load-bearing plate 312 can rise synchronously, thereby adjusting the height to a certain extent, enabling it to operate on the tobacco leaves at a specific height according to requirements, and then quickly conveying and processing the tobacco leaves through the conveyor belt 202 to a certain extent;

[0046] Utilize the conveying roller 302, shaft plate 303, cleaning rod 304, comb tooth rod 305, spiral cutter 306, auxiliary ring pipe 307, shaft rod 308, buffer plate 309, spring rod 310 and protective arc rod 311 to enable the electric push rod inside the load-bearing plate 312 to push the spring rod 310 and the connecting rod 314 synchronously, enabling it to quickly change the contact distance with the tobacco leaf stalk. At the same time, utilize the output motor 313 to drive the auxiliary ring pipe 307, so that the spiral cutter 306 cuts the tobacco leaves, and the tobacco leaves fall onto the conveying roller 302. The micro motor inside the fixed plate 301 conveys it to the upper surface of the conveyor belt 202, and then uses the conveyor belt 202 to transport it into the collection box 104 for collection and processing.

[0047] Embodiment 2:

[0048] Refer to Figure 3 - Figure 4 and Figures 6 - 7 Compared with Embodiment 1, the differences are as follows: A number of equally spaced conveying rollers 302 are rotatably connected to one side of the fixed plate 301. The upper surface of the fixed plate 301 is fixedly connected with a shaft plate 303. A shaft rod 308 is rotatably connected inside the shaft plate 303. An auxiliary ring pipe 307 is fixedly connected to the outer surface of the shaft rod 308. A spiral cutter 306 is fixedly connected to the outer surface of the auxiliary ring pipe 307. The edge of the spiral cutter 306 is set as a toothed structure. Among them, by setting the toothed structure at the edge of the spiral cutter 306, the spiral cutter 306 can cut the leaf stalk when it contacts the leaf stalk, and at the same time use the toothed structure to drive the cut leaves to prevent the leaves from directly falling after cutting, thereby reducing the collection effect of the equipment.

[0049] Furthermore, a buffer plate 309 is fixedly connected to the side of the spring rod 310 away from the load-bearing plate 312. A protective arc rod 311 is fitted and connected to one side of the buffer plate 309. The number of the protective arc rods 311 is two groups, and the two groups of protective arc rods 311 are both centrosymmetric about the center of the bearing frame 101. Among them, through the two symmetrically distributed protective arc rods 311, the equipment directly presses the plant rod as much as possible during operation, avoiding affecting the subsequent growth of tobacco leaves in other parts.

[0050] Furthermore, a cleaning rod 304 is inserted and connected to one side of the shaft plate 303. A comb-shaped rod 305 is fixedly connected to the lower surface of the cleaning rod 304. The inner tooth pitch of the comb-shaped rod 305 is adapted to the tooth pitch at the edge of the blade of the spiral cutter 306. One end of the shaft rod 308 is fixedly connected to one end of the output shaft of the output motor 313, and the output motor 313 is fixedly connected to one side of the fixing plate 301 through a machine base and an inclined support rod. Among them, through the cooperation between the comb-shaped rod 305 and the spiral cutter 306, it is prevented that the spiral cutter 306 continuously drives the blade during rotation, thereby causing the whole blade to be damaged by the spiral cutter 306.

[0051] Working principle: First, the cut tobacco leaves are received by the conveying roller 302, and the surface of the roller is covered with a silica gel layer. The leaves are gently conveyed to the L-shaped conveyor belt 202 through friction. The buffer plate 309 and the spring rod 310 form an elastic buffer layer to absorb the impact force of the leaves falling, avoiding leaf breakage. The two groups of protective arc rods 311 are symmetrically distributed on both sides of the tobacco plant. Their arc structures guide the equipment to avoid uncut leaves when moving. When the equipment contacts the tobacco plant, the protective arc rods 311 elastically retract through the spring rod 310, avoiding squeezing the stem, and ensuring the normal growth of subsequent leaves;

[0052] Secondly, the cleaning rod 304 rotates synchronously with the shaft rod 308, driving the comb-shaped rod 305 (the tooth pitch is matched with that of the spiral cutter 306) to clean the edge of the cutting blade reversely, peeling off the residual stem debris. The gap between the comb-shaped rod 305 and the cutter is controlled within 0.5 - 1 mm, which can effectively clean and avoid interfering with the cutting action. A limiting plate 215 is arranged inside the L-shaped conveyor belt 202. Through the linkage of the pulling rod 209 and the slide rail 205, the tension of the conveyor belt 202 is adjusted in real time to prevent tobacco leaves from piling up and jamming. The inclined plate 107 and the discharge chute 112 form a 30° inclination diversion structure to accelerate the sliding of tobacco leaves into the collection box 104.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
