[0001] The utility model relates to the technical field of tobacco harvesting tools, in particular to a tobacco harvesting tool for oriental tobacco. Background Technique

[0002] Oriental tobacco is a special type of tobacco, mainly used to enhance the aroma and taste of tobacco products. Compared with conventional tobacco, oriental tobacco has a unique fragrance and taste, which can improve the overall quality of tobacco products such as cigarettes. The cultivation history of oriental tobacco is long, and the earliest cultivation of oriental tobacco can be traced back thousands of years. Over time, the cultivation and processing techniques of oriental tobacco have been continuously improved, and there are more and more varieties.

[0003] At present, the harvesting of tobacco leaves relies on manual picking. Manual picking requires peeling the tobacco leaves one by one by hand, that is, separating the tobacco leaves from the tobacco stem, which is time-consuming and laborious, wastes a large amount of human resources, results in a large labor cost, and has low work efficiency. Therefore, there is an urgent need for a tool for harvesting the upper tobacco leaves of oriental tobacco to solve the above problems. Content of the Utility Model

Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0023] As Figure 1-2 shown, this embodiment provides an embodiment of a spice tobacco leaf harvesting tool. In this embodiment, the harvesting tool includes: a base 1, a variable-diameter disassembly mechanism, and a driving mechanism. The harvesting workpiece is used for separating tobacco stems and tobacco leaves.

[0024] Among them, refer to Figure 2-3, the base 1, the base 1 is fixedly installed on the ground, and rollers can also be installed on the base 1 to facilitate the movement of the base 1. The variable-diameter disassembling mechanism is installed on the base 1. The variable-diameter disassembling mechanism is equipped with multiple blades 303. The multiple blades 303 form a circle. The multiple blades are in contact with the tobacco stem. The variable-diameter disassembling mechanism changes the diameter of the circle formed by the multiple blades 303 as the diameter of the tobacco stem changes. The circle formed by the multiple blades 303 will come into contact with the stem of the tobacco. When the tobacco passes through the circle formed by the multiple blades 303, the multiple blades 303 will come into contact with the leaves on the tobacco stem. By cutting the leaves on the stem with the blades 303, the leaves can be separated from the stem. Generally, the diameter of the stem of a plant gradually decreases from bottom to top (this phenomenon is called "the decreasing arrangement of vascular bundles" in botany and is caused by uneven cell division and elongation during the growth of the plant. The stem of a tobacco plant contains vascular bundles, which are responsible for transporting water, nutrients, and organic substances. In the initial stage of tobacco growth, the vascular bundles at the base of the stem are relatively thick. As the plant grows, new vascular bundles will form above, and the original vascular bundles will no longer divide and thicken, resulting in a gradual decrease in the diameter of the stem from bottom to top.). Since the stem of the tobacco gradually decreases from bottom to top, when cutting the leaves on the stem, if the blade cannot fit the stem, the blade will directly contact the leaves, which is likely to damage the leaves. The variable-diameter disassembling mechanism can avoid this problem.

[0025] Furthermore, the variable-diameter disassembling mechanism includes a base plate 3 rotatably installed on the mounting plate 2, a limit ring 301 fixedly installed on the base plate 3, multiple driving rods 302 slidably installed on the limit ring 301, an adjusting ring 304 rotatably installed on the base plate 3, a connecting rod 305 rotatably installed on the adjusting ring 304 and the driving rods 302, a positioning ring 306 fixedly installed on the base plate 3, and multiple springs 307 fixedly installed on the positioning ring 306 and the adjusting ring 304. The blades 303 correspond to the driving rods 302 one by one and are fixedly connected. When the adjusting ring 304 is rotated, the rotation of the adjusting ring 304 drives the multiple connecting rods 305 to rotate. Through the rotation of the connecting rods 305, the driving rods 302 can be driven to slide on the limit ring 301. The multiple sliding driving rods 302 will drive the multiple blades 303 to slide, and thus the multiple blades 303 can move simultaneously, making the multiple blades 303 approach or move away from each other, so as to change the diameter of the circle formed between the multiple blades 303.

[0026] Further, when separating the stem of the tobacco and multiple leaves on the stem, by rotating the adjusting ring 304, the multiple blades 303 move away from each other. When the diameter of the circle formed by the multiple blades is greater than the maximum diameter on the tobacco stem, place the tobacco stem in the middle of the circle formed by the multiple blades 303, and then loosen the adjusting ring 304. Then, under the action of the spring 307, the adjusting ring 304 can be pulled to reset, causing the multiple blades 303 to gather together and the blades 303 to contact the tobacco stem. At this time, pulling the tobacco can drive the relative movement between the tobacco and the blades 303. The multiple blades 303 cut the connection between the leaves and the stem on the tobacco, so that the leaves on the tobacco can be separated from the tobacco stem, effectively improving the separation efficiency of the tobacco.

[0027] Preferably, when the tobacco stem moves between the multiple blades 303, since the diameter of the tobacco stem changes, under the action of the spring 307, the multiple blades 303 always have a tendency to move downward. The tobacco stem will limit the blades 303 in contact, preventing the blades 303 from continuing to contract under the action of the spring 307. As the diameter of the tobacco stem gradually decreases, under the action of the spring 307, the blades 303 contract, ensuring that the blades 303 of the tobacco dust can change with the change of the tobacco stem, so that the blades 303 can always fit the tobacco stem, preventing the blades 303 from directly contacting the leaves on the tobacco dust and preventing the blades 303 from cutting the tobacco leaves, ensuring the separation effect of the tobacco leaves.

[0028] Preferably, multiple handles 308 are fixedly installed on the adjusting ring 304, and a cutting hole 309 coaxial with the separation hole 201 is provided on the substrate 3. By rotating the handle 308, the adjusting ring 304 can be driven to rotate, facilitating manual adjustment of the diameter of the circle formed by the multiple blades 303. When separating the tobacco, place the tobacco stem inside the cutting hole 309, that is, in the middle of the multiple blades 303. The tobacco stem can pass through the separation hole 201, while the tobacco dust on the stem remains on one side close to the cutting hole 309.

[0029] Among them, referring to Figure 2 , the driving mechanism is installed on the base 1. The driving mechanism drives the multiple blades 303 to rotate, enabling the blades 303 to evenly cut the tobacco dust leaves. There will be a certain gap between the multiple blades 303, which causes the multiple blades 303 unable to cut the tobacco stem at any position. The driving mechanism can drive the blades 303 to rotate, and the rotating blades 303 will make up for the gap between two adjacent blades 303, thereby improving the cutting effect on the tobacco leaves.

[0030] Further, the driving mechanism includes a first gear 4 fixedly installed on the substrate 3, a second gear 401 rotatably installed on the mounting plate 2, and a first motor 402 fixedly installed on the mounting plate 2. The output shaft of the first motor 402 is coaxially and fixedly connected to the second gear 401. A mounting plate 2 is fixedly installed on the base 1. The mounting plate 2 is provided with a separation hole 201 through which the soot passes. The variable-diameter disassembly mechanism is installed on the mounting plate 2. By the first motor 402, the second gear 401 can be driven to rotate. Since the first gear 4 and the second gear 401 mesh with each other, the first gear 4 can be driven to rotate by the second gear 401. By the first gear 4, the substrate 3 can be driven to rotate, and thus a plurality of blades 303 can be driven to rotate.

[0031] Preferably, when the plurality of blades 303 rotate, the rotating blades 303 will generate centrifugal force. The centrifugal force will cause the plurality of blades 303 to tend to move away from each other. It should be noted that the centrifugal force is not sufficient to overcome the pressure indirectly applied by the spring 307 to the blades 303, which can ensure that the blades 303 always fit the tobacco.

[0032] Further, referring to Figure 1 , a conveyor belt 5 is fixedly installed on the base 1, and a second motor 501 is fixedly installed on the base 1. The output shaft of the second motor 501 is coaxially and fixedly connected to the transmission shaft of the conveyor belt 5. Two collection boxes 6 are fixedly installed on the base 1. The collection boxes 6 are located on both sides of the conveyor belt 5. When cutting the tobacco, the tobacco is placed on the conveyor belt 5. During the separation process of the tobacco, the stems of the tobacco can pass through the separation hole 201, while the soot on the stems remains on the conveyor belt 5. After the separation is completed, the second motor 501 is started to drive the conveyor belt 5 to rotate. The rotating conveyor belt 5 will drive the tobacco leaves on the conveyor belt 5 to move, and the tobacco leaves can be conveyed into the collection boxes 6 for collection.

[0033] When the tobacco is cut in the utility model, the tobacco is placed on the conveyor belt 5, and the stem of the tobacco is placed inside the cutting hole 309. Under the action of the spring 307, the adjusting ring 304 is pulled, so that the multiple blades 303 are gathered together, and the blades 303 are in contact with the stem of the tobacco. The substrate 3 can be driven to rotate by the first motor 402, and thus the multiple blades 303 can be driven to rotate. At this time, when the tobacco is pulled, the relative movement between the tobacco and the blades 303 can be driven. The connection between the leaves and the stem on the tobacco is cut by the multiple blades 303, so that the leaves on the tobacco can be separated from the stem of the tobacco, and the separation efficiency of the tobacco can be effectively improved. As the diameter of the tobacco stem gradually decreases, under the action of the spring 307, the blades 303 contract, ensuring that the blades 303 of the tobacco dust can change with the change of the tobacco stem, so that the blades 303 can always fit with the stem of the tobacco, preventing the blades 303 from directly contacting the leaves on the tobacco dust and preventing the blades 303 from cutting the tobacco leaves, ensuring the separation effect of the tobacco leaves. Finally, the stem of the tobacco can pass through the separation hole 201, and the tobacco dust on the stem remains on the conveyor belt 5. After the separation is completed, the second motor 501 is started to drive the conveyor belt 5 to rotate, and the rotating conveyor belt 5 will drive the tobacco leaves on the conveyor belt 5 to move, and the tobacco leaves can be conveyed into the collection box 6 for collection.

For those skilled in the art, any equivalent modification or substitution to the utility model is also within the scope of the utility model.
