Description

Technical Field

[0001] This invention relates to the field of tobacco harvesting technology, specifically an automatic tobacco harvesting device. Background Technology

[0002] Tobacco is an important economic crop in my country's national economy. Harvesting is a fundamental task in tobacco production; timely and scientific harvesting ensures the quality of the tobacco leaves. Currently, the vast majority of tobacco harvesting methods in my country are still manual, requiring significant manpower and time, and often resulting in untimely harvesting. With extremely large harvest volumes, manual harvesting is insufficient and prone to missing the optimal harvest time. While automated tobacco harvesters on the market offer high harvesting efficiency and require less labor, they cause significant damage to the tobacco leaves, hindering later processing. Furthermore, existing automated harvesting devices are structurally complex and cannot achieve fully automated harvesting. Moreover, the layered cutting and harvesting of tobacco leaves based on height results in fragmented leaves that are difficult to distinguish from the stalks, negatively impacting tobacco quality.

[0003] The announcement number is CN115316121B, which discloses a fully automatic tobacco leaf harvesting device. This device automatically harvests tobacco leaves and whole tobacco plants, then strings them together without cutting or damaging the leaves during the harvesting process. The device also provides good transport efficiency for the tobacco leaves during whole-plant harvesting, ensuring tobacco quality. However, when the tobacco is strung together, the device does not intervene in the position and angle of the tobacco falling onto the first transport section, allowing it to fall freely. Although the position can be adjusted via an adjustment section, the adjustment range is limited because the tobacco plants only pass through this section. This results in the tobacco plants easily falling directly from the second transport section or being unevenly positioned, leading to a messy and disorganized finished product that is difficult to unload later.

[0004] Based on this, an automatic tobacco harvesting device is now provided, which can eliminate the drawbacks of existing devices. Summary of the Invention

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] Example 1

[0031] In one embodiment, such as Figures 1-8As shown, an automatic tobacco harvesting device includes a vehicle body 11 and guide boxes 14. A storage box 12 is fixedly mounted on the vehicle body 11. A door 13 is hinged to one side of the storage box 12. The storage box 12 is equipped with a locking component for fixing the door 13. Two guide boxes 14 are symmetrically arranged, and a connecting plate is fixedly mounted between the guide boxes 14. A cutting disc 15 is rotatably mounted inside each guide box 14. The two cutting discs 15 are symmetrically arranged. One end of the rotating shaft of the cutting disc 15 is fixedly connected to the output end of a first motor 17. The first motor 17 is fixedly mounted on the upper end of the guide box 14. A support turntable 16 is fixedly mounted on one end of the rotating shaft of the cutting disc 15. Both guide boxes 14 are fixedly mounted at one end of a transmission box 19, and the other end of the transmission box 19 is fixedly mounted on one side of the storage box 12. Inside the mounting slot, the transmission box 19 is symmetrically equipped with a transmission belt 20. Several fixed blades are fixedly installed on the transmission belt 20 at equal intervals. The transmission box 19 is equipped with a drive assembly for rotating the transmission belt 20. A clamping belt 22 is symmetrically installed at one end of the transmission box 19. A gathering rod 27 is provided inside the storage box 12 between one end of the two clamping belts 22. The storage box 12 is equipped with a support mechanism for supporting the gathering rod 27. A placement box 29 is fixedly installed at the bottom of the storage box 12. Several gathering rods 27 are provided inside the placement box 29. The placement box 29 is equipped with a conveying mechanism for continuously conveying the gathering rods 27. The support mechanism facilitates the support of the gathering rods 27 loaded with tobacco, and the conveying mechanism facilitates the quick replacement and conveying of the gathering rods 27.

[0032] The driving assembly includes a first driving roller and a first transmission roller. The first driving roller and the first transmission roller are respectively fitted at both ends of the conveyor belt 20. Both the first driving roller and the first transmission roller are rotatably mounted inside the transmission box 19. One end of the rotating shaft of the first driving roller is fixedly connected to the output end of a second motor 21. The second motor 21 is fixedly mounted at one end of the transmission box 19. The clamping belt 22 is respectively fitted at both ends with a second driving roller and a second transmission roller. The rotating shafts at both ends of the second driving roller and the second transmission roller are rotatably mounted in the rotating holes at both ends of two retaining plates. One of the retaining plates is fixedly mounted at one end of the transmission box 19. In use, when it is necessary to harvest tobacco plants... At that time, the vehicle body 11 moves the guide box 14, so that the tobacco plant is located between the two guide boxes 14. At the same time, the first motor 17 and the second motor 21 are started. When the support turntable 16 approaches the tobacco plant, the two support turntables 16 cooperate to limit the tobacco plant. Then the cutting disc 15 cuts the tobacco plant. As the vehicle body 11 continues to move the guide box 14, the unharvested tobacco plants will limit and support the harvested tobacco plants as the tobacco plants move. Then the harvested tobacco plants are pushed between the two conveyor belts 20. A fixed blade on the two conveyor belts 20 is inserted into the root of the tobacco plant to fix the tobacco plant. At the same time, when the conveyor belts 20 rotate, the tobacco plants can be transported.

[0033] Each guide box 14 has a rotating plate 18 rotatably mounted on one end. The rotating plate 18 is connected to the guide box 14 with a torsion spring. In use, it is convenient to support the harvested tobacco plants and prevent them from falling over.

[0034] The support mechanism includes a placement frame 23, with support legs 24 fixedly arranged around the bottom of the placement frame 23. Each support leg 24 has a caster wheel at one end. Each gathering rod 27 has a limiting plate 28 fixedly arranged at one end. A first limiting groove is provided on the inner side of the placement frame 23 corresponding to the limiting plate 28. A second limiting groove is provided on the inner side of the placement frame 23 corresponding to one end of the gathering rod 27. The end of the first limiting groove is tightly aligned with one end of the storage box 29. A limiting frame 25 is provided at the bottom of the storage box 12, corresponding to the positions of several support legs 24. The limiting frame 25 is fixedly arranged at the bottom of the storage box 12. A fixing rod 26 is provided on one side of the box door 13, corresponding to the position of the limiting frame 25. The fixing rod 26 is tightly aligned with two support legs 24. An installation box 37 is connected to the placement frame 23 at the position corresponding to one end of the first limiting groove. The installation box 37 is fixedly arranged at the bottom of the placement frame 23. A sliding locking block 3 is provided inside the installation box 37. 4. Several first return springs 36 are provided between the bottom end of the locking block 34 and the bottom end of the mounting box 37. The bottom end of the locking block 34 is fixedly connected to the output ends of several telescopic rods 35. The telescopic rods 35 are all fixedly installed at the bottom end of the mounting box 37. The upper end of the locking block 34 is provided with an arc-shaped groove, which is located between the two clamping straps 22. In use, when supporting the retracting rod 27, the limiting plate 28 at one end of the retracting rod 27 slides on the first limiting plate. Inside the groove, one end of the gathering rod 27 is slidably positioned in the second limiting groove. As a result, the number of gathering rods 27 inside the placement frame 23 gradually increases, causing several limiting discs 28 to fit tightly one by one, thus arranging the gathering rods 27 neatly. At the same time, when the tobacco is fixed on the gathering rod 27, one end of the limiting disc 28 of the gathering rod 27 is located in the arc-shaped groove at the upper end of the locking block 34, thereby fixing the gathering rod 27 and preventing the gathering rod 27 from moving when the tobacco is fixed on it.

[0035] The bottom end of the locking block 34 is fixed with a pull rod, one end of which is equipped with a pedal. The pull rod extends to the outside of the mounting box 37. When it is necessary to disassemble several gathering rods 27 inside the placement rack 23, the locking block 34 can be moved by pulling the pedal and the pull rod to release the fixation of the limiting plate 28 and remove the several gathering rods 27.

[0036] The conveying mechanism includes a pusher plate 30, which is slidably disposed inside the placement box 29. One end of the pusher plate 30 is fixedly connected to one end of the connecting frame, and the other end of the connecting frame is fixedly connected to the output end of the first electric push rod 31. The first electric push rod 31 is fixedly disposed at the bottom of the storage box 12. A fixing plate 32 is provided at one end of the placement box 29 corresponding to the position of the limiting plate 28. The fixing plate 32 is fixedly connected to the placement box 29 by screws. A fixing box is connected to one end of the placement box 29. A second electric push rod 33 is fixedly disposed inside the fixing box. A push block is fixedly disposed at the output end of the second electric push rod 33. In use, when it is necessary to replace the gathering rod 27, the first electric push rod 31 is activated, and the first electric push rod 31 drives the pusher plate 30 to move one diameter of the limiting plate 28. The distance causes a limiting disc 28 to move to the push block position. Then, the second electric push rod 33 is activated. The output end of the second electric push rod 33 pushes one end of the limiting disc 28 of the retracting rod 27 to move. The limiting disc 28 first comes into close contact with one side of the locking block 34. As the limiting disc 28 continues to move, the locking block 34 slides inside the mounting box 37. Then, the two limiting discs 28 come into close contact. The output end of the second electric push rod 33 continues to push the limiting disc 28 to move, so that the limited disc 28 after loading is disengaged from the upper end of the locking block 34. The unused limiting disc 28 moves into the arc groove at the upper end of the locking block 34. Then, the output end of the second electric push rod 33 returns to the initial position. Under the action of the first return spring 36, the locking block 34 returns to the initial position, thereby fixing the limiting disc 28 and completing the switching of the retracting rod 27.

[0037] The inner side of the placement rack 23 is provided with a mounting groove corresponding to the position of the locking block 34. A first control button 44 is fixedly installed in the mounting groove. A first sliding plate 42 is provided on one side of the trigger end of the first control button 44. A guide rod is slidably mounted on the first sliding plate 42. The guide rod is fixedly mounted on one side of the mounting box 37. A tension spring 43 is provided between one side of the first sliding plate 42 and one end of the guide rod. A sliding tube 40 is slidably mounted on each of the gathering rods 27. A second return spring 41 is fixedly installed at one end of each sliding tube 40. The other end of the spring 41 is fixedly connected to one side of the circular plate, which is fixedly mounted on the gathering rod 27. The first control button 44 is electrically connected to the external control component. In use, when there are too many tobacco plants fixed on the gathering rod 27, the tobacco plants slide on the gathering rod 27, causing the tobacco plants at the end to push the sliding tube 40 to slide. The sliding tube 40 pushes the first sliding plate 42 to slide. When the number of tobacco plants on the gathering rod 27 reaches the limit, the first sliding plate 42 squeezes the trigger end of the first control button 44, thereby causing the control component to replace the gathering rod 27.

[0038] A second control button 45 is fixedly provided at one end of the first limiting groove. A second sliding plate is provided on one side of the trigger end of the second control button 45. The second sliding plate is slidably disposed in the first limiting groove. A third return spring 46 is provided between one side of the second sliding plate and one side of the first sliding groove. The second control button 45 is electrically connected to an external control component. In use, when the number of gathering rods 27 loaded inside the placement rack 23 reaches the limit, as the limiting plate 28 at one end of the last gathering rod 27 moves to the upper end of the locking block 34, the last limiting plate 28 presses the trigger end of the second control button 45 through the second sliding end. When the sliding tube 40 on the last gathering rod 27 triggers the first control button 44, the external control component reminds the staff to stop working, so that the placement rack 23 can be replaced before work can be resumed.

[0039] Example 2

[0040] The difference from Embodiment 1 is that a guide plate 38 is provided on one side of the storage box 12, corresponding to one end of the clamping strap 22. One end of the guide plate 38 is inclined. In use, after the tobacco is fixed on the gathering rod 27, the guide plate 38 guides the tobacco, causing the eyeball to tilt to one side. Then, under the action of the gravity of the eyeball, the other end of the tobacco is downward.

[0041] Example 3

[0042] The difference from Embodiment 1 is that: a gathering frame 39 is fixedly provided at the position corresponding to one end of the second limiting groove of the placement frame 23. The gathering frame 39 is inclined and has a through groove in the middle. When in use, it is convenient to squeeze the tobacco at one end of the gathering rod 27 when switching the gathering rod 27, so that one end of the gathering rod 27 can move into the second limiting groove.

[0043] The above embodiment discloses an automatic tobacco harvesting device. When tobacco plants need to be harvested, the vehicle body 11 moves the guide boxes 14, positioning the tobacco plants between the two guide boxes 14. Simultaneously, the first motor 17 and the second motor 21 are activated. When the support turntables 16 approach the tobacco plants, the two support turntables 16 cooperate to limit the movement of the tobacco plants. Then, the cutting disc 15 cuts the tobacco plants. As the vehicle body 11 continues to move the guide boxes 14, unharvested tobacco plants will limit and support the harvested tobacco plants as they move. The harvested tobacco plants are then pushed between two conveyor belts 20. A fixed blade on each conveyor belt 20 is inserted into the root of the tobacco plant to fix it in place. Simultaneously, as the conveyor belts 20 rotate, they can cut the tobacco plants. The tobacco plants are transported. After leaving the conveyor belt 20, the tobacco plants are positioned between two clamping belts 22, which hold and fix them in place. As more tobacco plants are added between the two clamping belts 22, they are gradually fixed onto the gathering rod 27. When too many tobacco plants are fixed onto the gathering rod 27, they slide on it, causing the tobacco plants at the ends to push the sliding tube 40 to slide. The sliding tube 40 then pushes the first sliding plate 42 to slide. When the number of tobacco plants on the gathering rod 27 reaches its limit, the first sliding plate 42 presses against the trigger end of the first control button 44. The external control component activates the first electric push rod 31, which moves the push plate 30 a distance equal to the diameter of a limit plate 28, causing one... The limiting disc 28 moves to the push block position, and then the second electric push rod 33 is activated. The output end of the second electric push rod 33 pushes one end of the limiting disc 28 of a retracting rod 27 to move. The limiting disc 28 first comes into close contact with one side of the locking block 34. As the limiting disc 28 continues to move, the locking block 34 slides inside the mounting box 37. Then, the two limiting discs 28 come into close contact, and the output end of the second electric push rod 33 continues to push the limiting disc 28 to move, so that the limited disc 28 after loading disengages from the upper end of the locking block 34. The unused limiting disc 28 moves into the arc-shaped groove at the upper end of the locking block 34. Then, the output end of the second electric push rod 33 returns to the initial position. Under the action of the first return spring 36, the locking block 34 returns to the initial position, thereby fixing the limiting disc 28. After switching the gathering rod 27, the gathering frame 39 squeezes the tobacco at one end of the gathering rod 27, making it easier for one end of the gathering rod 27 to move into the second limiting groove. When the number of gathering rods 27 loaded inside the placement frame 23 reaches its limit, as the limiting plate 28 at one end of the last gathering rod 27 moves to the upper end of the locking block 34, the last limiting plate 28 squeezes the trigger end of the second control button 45 through the second sliding end. When the sliding tube 40 on the last gathering rod 27 triggers the first control button 44, the external control component reminds the operator to stop working. The operator opens the box door 13, then removes the placement frame 23 containing the gathering rods 27, and replaces the unused placement frame 23, so that work can be resumed.

[0044] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
