Description

Technical Field

[0001] This utility model relates to the technical field of tobacco leaf picking equipment, specifically to a precise picking and positioning protection device for fresh tobacco leaves. Background Technology

[0002] In the tobacco planting industry, the harvesting of fresh tobacco leaves is a crucial step that affects the quality of subsequent processing. Traditionally, fresh tobacco leaf harvesting relies mainly on manual labor. Harvesters must manually select the parts to pick based on the maturity of the leaves. This is not only labor-intensive and inefficient, but also prone to errors due to differences in human experience, resulting in the wrong picking of immature leaves or the omission of mature leaves, directly affecting the overall quality of the tobacco. With the development of agricultural mechanization, some tobacco harvesting equipment has been gradually applied to production, but existing equipment has significant shortcomings in terms of precise positioning and protection. Most equipment adopts batch cutting harvesting, which cannot accurately locate different mature parts of individual tobacco leaves. For example, the tobacco cultivation and harvesting method disclosed in patent CN104429460A still cannot solve the problem of precise positioning in practical applications. A large number of non-target tobacco leaves and plant stems are harvested or damaged along with the leaves, increasing the workload of subsequent sorting and damaging the regenerative capacity of the tobacco plants, affecting the yield of subsequent batches. In addition, during the transportation process after harvesting, due to the lack of effective protective structures, fresh tobacco leaves are easily damaged and moldy due to collisions and compression, further reducing the commercial value of the tobacco leaves. Related research, such as "The Influence of Different Harvesting Methods of Upper Leaves on Tobacco Leaf Quality," conducted a field comparative experiment, setting up different harvesting treatments. The results showed that unreasonable harvesting and subsequent treatment have a significant impact on tobacco leaf quality. Utility Model Content

[0003] The purpose of this invention is to provide a precise picking and positioning protection device for fresh tobacco leaves, in order to solve the problem mentioned in the background art that a large number of non-target tobacco leaves and plant stems are picked or damaged along with the tobacco leaves, which increases the workload of subsequent sorting and also damages the regeneration capacity of the tobacco plants, affecting the yield of subsequent batches.

[0004] To achieve the above objectives, this utility model provides a precise picking and positioning protection device for fresh tobacco leaves, including a truck. One end of the truck is connected to a conveying component. The conveying component includes an inclined conveying trough, and a shovel is installed at the lower end of the conveying trough. The truck moves to drive the shovel to precisely pick the fresh tobacco leaves and transport them into the truck through the conveying component. The conveying component is adjusted in height by a lifting screw slide.

[0005] This setup uses a truck as a mobile carrier. One end of the conveying component includes an inclined conveying trough. The shovel at the bottom of the conveying trough moves with the truck to harvest fresh tobacco leaves. At the same time, the conveying component is adjusted in height via a lifting screw slide.

[0006] Preferably, side baffles are installed on the inner walls of both sides of the feeding trough, and the surface of the side baffles is fitted with limiting protrusions made of rubber material, which limit the harvested fresh tobacco plants.

[0007] This feature involves installing rubber limiting protrusions on the side baffles on both sides of the inner wall of the feeding trough, using the elasticity of the rubber and the structure of the protrusions to limit the movement of the harvested fresh tobacco plants.

[0008] Preferably, the other end of the truck is connected to a finished product warehouse, and an inclined vibrating screen plate is installed inside the truck. One end of the vibrating screen plate is provided with a finished product discharge port, which is connected to the finished product warehouse.

[0009] This feature connects the other end of the truck to the finished product warehouse, where an inclined vibrating screen is installed. The finished product outlet at one end of the screen is connected to the finished product warehouse, allowing the tobacco leaves that enter the truck via the conveying components to be screened on the vibrating screen before entering the finished product warehouse through the outlet.

[0010] Preferably, the vibrating screen plate is vibrated and screened by a vibrating motor.

[0011] This setting features a vibrating screen plate driven by a vibrating motor, which uses vibration to separate tobacco leaves from impurities. The effect is to enhance the screening efficiency through vibration.

[0012] Preferably, a waste trough is provided below the vibrating screen plate.

[0013] This feature includes a waste trough located below the vibrating screen plate to collect the screened impurities.

[0014] Preferably, a conveyor belt is installed inside the conveying trough, an inlet is provided at the lower end of the conveying trough, and an outlet is provided at the upper end of the conveying trough.

[0015] This device uses a conveyor belt inside the feeding trough to transport fresh tobacco leaves from the lower feed inlet to the upper discharge outlet, thus completing the tobacco leaf transfer.

[0016] Preferably, the surface of the conveyor belt is uniformly distributed with elastic protrusions, the elastic protrusions are arranged along the conveying direction of the conveyor belt, and the spacing between adjacent elastic protrusions is 5-8cm.

[0017] This feature involves setting elastic raised strips on the surface of the conveyor belt along the conveying direction, with adjacent strips spaced 5-8cm apart. The raised strips can provide some obstruction and separation for the tobacco leaves.

[0018] Preferably, the limiting protrusion has a hemispherical structure, and the diameter of the limiting protrusion is 2-3cm, and the distance between adjacent limiting protrusions is 8-10cm.

[0019] The hemispherical rubber limiting protrusions are 2-3cm in diameter and 8-10cm apart. This structure and size design can better fit the fresh tobacco plant and play a limiting role.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: In this precise fresh tobacco leaf picking and positioning protection device, the device uses a moving truck to drive a shovel for picking, and a lifting screw slide to drive the material conveying components to adjust their height. It can precisely control the picking position according to the height of the tobacco plant and the maturity of the tobacco leaves, effectively avoiding the problems of mispicking immature tobacco leaves or missing mature tobacco leaves due to differences in experience in traditional manual picking. At the same time, it overcomes the problem of non-target tobacco leaves and plant stem damage caused by the batch cutting picking of existing equipment, reduces the damage to the regeneration capacity of tobacco plants, and ensures the yield of subsequent batches. The side baffles and rubber limiting protrusions on the inner walls of the conveyor trough stabilize and limit the fresh tobacco plants after harvesting, preventing them from colliding due to shaking during transport. The evenly distributed elastic protrusions (5-8cm spacing) on ​​the conveyor belt surface form an orderly conveying channel, reducing compression and friction between tobacco leaves. Hemispherical limiting protrusions (2-3cm diameter, 8-10cm spacing) further buffer the impact during transport, preventing damage to the fresh tobacco leaves. These protective structures effectively solve the problems of easy damage and mold growth of tobacco leaves during transport in existing equipment, significantly improving the commercial value of the tobacco leaves. The tilted vibrating screen inside the truck vibrates and screens the material under the drive of a vibrating motor, separating the harvested tobacco leaves from impurities. The impurities fall into the waste trough below, while the clean finished tobacco leaves enter the finished product warehouse through the finished product discharge outlet. This realizes the integrated automated operation of harvesting, conveying, and sorting, which greatly reduces the workload of subsequent manual sorting, solves the efficiency bottleneck of traditional equipment that requires additional sorting steps, and improves the overall production efficiency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides a precise positioning and protection device for harvesting fresh tobacco leaves, such as... Figure 1 , Figure 3 As shown, the device includes a truck 1, one end of which is connected to a material conveying component 2. The material conveying component 2 includes an inclined material conveying trough 21, and a shovel 23 is installed at the lower end of the material conveying trough 21. The truck 1 moves to drive the shovel 23 to accurately pick fresh tobacco leaves, which are then conveyed into the truck 1 through the material conveying component 2. The material conveying component 2 is driven to lift and adjust by a lifting screw slide 3.

[0024] The device uses a truck 1 as a mobile carrier. One end of the conveying component 2 includes an inclined conveying trough 21. A shovel 23 at the lower end of the conveying trough 21 moves with the truck 1 to harvest fresh tobacco leaves. Simultaneously, the conveying component 2 is adjusted in height via a lifting screw slide 3. The effect is that by using the movement of the truck 1 to drive the shovel 23, combined with the lifting adjustment, it can adapt to tobacco plants of different heights, accurately locate the harvesting position, improve harvesting efficiency, and lay the foundation for subsequent precise harvesting, making the harvesting operation more flexible and efficient.

[0025] In this embodiment, as Figure 4 As shown, side baffles 213 are installed on the inner walls of both sides of the feeding trough 21, and rubber limiting protrusions 214 are installed on the surface of the side baffles 213. The limiting protrusions 214 limit the harvested fresh tobacco plants.

[0026] Rubber limiting protrusions 214 are installed on the side baffles 213 on both sides of the inner wall of the feeding trough 21. The elasticity of the rubber and the structure of the protrusions limit the movement of the harvested fresh tobacco plants. The effect is to effectively prevent the fresh tobacco leaves from swaying and colliding during the feeding process. The rubber material can also reduce hard damage to the tobacco leaves, ensure the integrity of the fresh tobacco leaves, and improve the quality of the tobacco leaves.

[0027] Specifically, such as Figure 1 , Figure 2As shown, the other end of the truck 1 is connected to the finished product warehouse 4. An inclined vibrating screen plate 11 is installed inside the truck 1. One end of the vibrating screen plate 11 is provided with a finished product outlet 14, which is connected to the finished product warehouse 4.

[0028] The other end of the truck 1 is connected to the finished product warehouse 4, which is equipped with an inclined vibrating screen plate 11. The finished product outlet 14 at one end of the screen plate is connected to the finished product warehouse 4, so that the tobacco leaves entering the truck 1 through the conveying component 2 can be screened on the vibrating screen plate 11 and then enter the finished product warehouse 4 through the outlet. The effect is to realize the integration of preliminary screening and collection of tobacco leaves after harvesting. The inclined vibrating screen plate 11 facilitates the movement of tobacco leaves to the finished product outlet 14, improving the convenience and efficiency of tobacco leaf collection.

[0029] Furthermore, such as Figure 1 , Figure 2 As shown, the vibrating screen plate 11 vibrates and screens the material via the vibrating motor 12.

[0030] The vibrating screen plate 11 is driven by the vibrating motor 12 to generate vibration, which separates the tobacco leaves from impurities. The effect is that the vibration enhances the screening effect, which can more efficiently screen out impurities in the tobacco leaves, improve the purity of the tobacco leaves, and reduce the amount of manual sorting work in the subsequent process.

[0031] Furthermore, such as Figure 1 , Figure 2 As shown, a waste trough 13 is provided below the vibrating screen plate 11.

[0032] A waste trough 13 is provided below the vibrating screen plate 11 to collect the screened impurities. This achieves centralized collection of impurities, prevents impurities from accumulating and affecting the operation of the vibrating screen plate 11, keeps the inside of the device clean, and facilitates subsequent processing of the impurities.

[0033] Furthermore, such as Figure 3 , Figure 4 As shown, a conveyor belt 22 is installed inside the conveying trough 21, a feed inlet 211 is provided at the lower end of the conveying trough 21, and a discharge outlet 212 is provided at the upper end of the conveying trough 21.

[0034] The conveyor belt 22 inside the feeding trough 21 transports fresh tobacco leaves from the lower feed inlet 211 to the upper discharge outlet 212, completing the transfer of tobacco leaves. This achieves automated transport of tobacco leaves from harvesting to entering the truck 1, replacing manual handling, saving manpower, and improving overall operational efficiency.

[0035] Furthermore, the surface of the conveyor belt 22 is uniformly distributed with elastic protrusions, which are arranged along the conveying direction of the conveyor belt, and the spacing between adjacent elastic protrusions is 5-8cm.

[0036] The elastic raised strips on the surface of the conveyor belt 22 are arranged along the conveying direction, with an adjacent spacing of 5-8cm. The raised strips can play a certain role in blocking and separating the tobacco leaves. The effect is to prevent the tobacco leaves from slipping and piling up during the conveying process, ensuring the orderly conveying of the tobacco leaves. The elastic material can also reduce the squeezing damage to the tobacco leaves. At the same time, the reasonable spacing design is adapted to the size of fresh tobacco leaves to ensure the conveying effect.

[0037] Furthermore, the limiting protrusion 214 has a hemispherical structure, and the diameter of the limiting protrusion 214 is 2-3cm, and the distance between adjacent limiting protrusions 214 is 8-10cm.

[0038] The hemispherical rubber limiting protrusions 214 have a diameter of 2-3 cm and an adjacent spacing of 8-10 cm. This structure and size design allows for a better fit to the fresh tobacco plant, effectively limiting its movement. The hemispherical structure reduces the contact area with the tobacco leaves, decreasing pressure on them. The appropriate diameter and spacing effectively limit movement without overly restricting the leaves, further protecting them from damage.

[0039] The precision harvesting and positioning protection device for fresh tobacco leaves of this utility model is used primarily during the harvesting process. Using a truck 1 as a mobile carrier, the truck 1 travels along a set path during operation. The material conveying component 2, connected to one end, is raised and lowered by a lifting screw slide 3, thereby adjusting the shovel 23 at the lower end of the material conveying trough 21 to a height matching the fresh tobacco leaves to be harvested. As the truck 1 moves, the shovel 23 precisely cuts and harvests the fresh tobacco leaves, achieving precise harvesting of mature tobacco leaves from tobacco plants at different heights. Next is the conveying process. The harvested fresh tobacco leaves enter the conveying trough 21 through the inlet 211 at the lower end of the trough, and the conveyor belt 22 inside the trough 21 begins to operate. The elastic protrusions on the surface of the conveyor belt 22, evenly distributed along the conveying direction with an adjacent spacing of 5-8 cm, act as barriers and dividers for the tobacco leaves, preventing slippage and accumulation, and ensuring orderly upward conveying. Simultaneously, the rubber limiting protrusions 214 on the side baffles 213 on both sides of the conveying trough 21 are hemispherical, with a diameter of 2-3 cm and an adjacent spacing of 8-10 cm. The elasticity of the rubber limits the movement of the tobacco plants, preventing them from swaying or colliding during conveying, reducing hard damage. Finally, the tobacco leaves enter the truck 1 through the outlet 212 at the upper end of the conveying trough 21. Next comes the screening process. The tobacco leaves entering the truck 1 fall onto the inclined vibrating screen plate 11 installed inside. The vibration motor 12 starts, driving the vibrating screen plate 11 to vibrate. Under the action of vibration, the tobacco leaves are separated from the impurities mixed in, such as soil and dead leaves. The impurities fall through the screen holes of the vibrating screen plate 11 into the waste trough 13 below, realizing the centralized collection of impurities. Finally, there is the collection stage. After being screened, the clean fresh tobacco leaves move towards the finished product outlet 14 under the guidance of the inclined vibrating screen plate 11, and enter the finished product warehouse 4 connected to the other end of the truck 1 through the finished product outlet 14, completing the entire process of picking, conveying, screening and collecting fresh tobacco leaves.
