Description

Technical Field

[0001] This utility model belongs to the technical field of tobacco harvesting equipment, and in particular relates to a combined tobacco harvesting machine that integrates harvesting and clamping. Background Technology

[0002] In the current tobacco production process, the harvesting stage is still mainly done manually, which has problems such as high labor intensity, low efficiency, and long operation cycle. Tobacco harvesting needs to be completed in a short period of time to ensure the maturity and quality of tobacco leaves. However, relying on manual picking and transportation of each plant is not only inefficient, but also easily causes worker fatigue and affects the quality of harvesting. Although some areas have introduced small and medium-sized harvesting or transportation machinery, most of them have single functions and can only complete field transportation or partial handling work. There is a lack of integrated machinery that can realize continuous "picking-transfer-sorting" operations. After the tobacco leaves are picked, they need to be sorted again and bundled into bunches, which increases the operation steps and labor input. In addition, secondary damage to tobacco leaves can be caused during transportation, affecting the quality of tobacco leaves. Utility Model Content

Detailed Implementation

[0019] like Figure 1-4 As shown, a combined tobacco harvester integrating harvesting and clamping includes a frame 1, a track 2 at the lower end of the frame 1, a collection platform 4 at the upper end of the frame 1, two harvesting devices 3 at the rear end of the frame 1 in the forward direction, a conveying device 7 between the collection platform 4 and the two harvesting devices 3, a tobacco leaf sorting device 5 and a tobacco clamp 6 on the collection platform 4, and a power device for driving the track 2 to move on the frame 1.

[0020] This design features two working platforms on the frame 1. The first platform is used for harvesting, where two harvesters can sit directly on the harvesting device 3 to harvest the tobacco plants. The second platform is used for collection and sorting, where one collector sorts, clamps, and shelves the tobacco leaves on the tobacco leaf sorting device 5 and the tobacco clamp rack 6. The two levels are connected by a conveyor device 7 to achieve continuous transport of tobacco leaves, reducing the need for traditional manual handling, avoiding secondary damage during tobacco leaf transport, and ensuring the quality of the tobacco leaves.

[0021] Using a tracked chassis as the mobile base platform, it has anti-slip and wear-resistant properties, and can maintain good traction in soft soil and wet environments, ensuring that the equipment can still travel stably in complex terrain.

[0022] The tobacco leaf combine harvester also includes a control system, which has a unified control function for walking drive and conveying drive. Operators can adjust the walking speed and conveying speed according to the harvesting progress to keep picking, conveying and sorting coordinated. At the same time, the control system can realize start-stop control and emergency braking to ensure the safety of equipment operation.

[0023] The harvesting device 3 includes a mounting frame 301, which is fixedly connected to the frame 1, and a harvesting seat 302 is fixedly mounted on the mounting frame 301.

[0024] The collection platform 4 includes a base plate 401, which is fixedly connected to the frame 1, and a fence 402 is fixedly attached to the top of the base plate 401.

[0025] The tobacco leaf sorting device 5 includes a sorting table assembly 501, a clamping assembly 502, and a plurality of tobacco leaf clamps 503. The sorting table assembly 501 is fixedly installed on the base plate 401, and the clamping assembly 502 is disposed on the sorting table assembly 501. The clamping assembly 502 can fix the tobacco leaves on the sorting table assembly 501 onto the tobacco leaf clamps 503 to form tobacco leaf strings.

[0026] This design makes it easy to fix loose tobacco leaves onto the tobacco leaf clip 503 to form tobacco leaf bunches, and then neatly place the tobacco leaf bunches on the tobacco clip rack 6 to achieve the shaping and neat storage of tobacco leaves, which facilitates subsequent transportation and curing processes.

[0027] The sorting table assembly 501 includes a sorting table 5011, which is fixedly connected to the base plate 401 via support legs.

[0028] The clamping assembly 502 includes a rotating shaft 5021, which is rotatably connected to one end of the sorting table 5011. Two connecting blocks 5022 are fixedly connected to the rotating shaft 5021, and a pressure block 5023 is fixedly connected to the end of the two connecting blocks 5022 away from the rotating shaft 5021.

[0029] The connecting block 5022 has an arc-shaped structure.

[0030] In addition to this embodiment, the number of connecting blocks 5022 can be more than two.

[0031] A support block 5025 is fixedly connected to the sorting table 5011. The support block 5025 is set in correspondence with the pressure block 5023. A cigarette clip installation groove 5026 is opened on the top surface of the support block 5025.

[0032] Two handles 5024 are fixedly installed on the pressure block 5023.

[0033] In addition to this embodiment, the number of handles 5024 can also be one.

[0034] The tobacco leaf clip 503 includes a fixing block 5031, and multiple fixing pins 5032 are fixedly attached to the fixing block 5031.

[0035] With this design, when the collector is operating, he first lays the tobacco leaves that have been conveyed up on the sorting table 5011, then places the tobacco leaf clip 503 on top of the support block 5025, presses the fixing block 5031 so that the fixing pin 5032 passes through the tobacco leaf and enters the tobacco clip mounting slot 5026, and finally pulls the handle 5024 to complete the pressing action.

[0036] During the pressing process, the pressing block 5023 applies uniform pressure to the tobacco leaves, neatly clamping the flat tobacco leaves into the tobacco leaf clamp 503 to form standardized tobacco leaf bunches. The tobacco leaf bunches can be directly placed on the tobacco clamp rack 6, ensuring the efficiency and continuity of the sorting process.

[0037] The clamping assembly 502 has a simple structure, intuitive operation, high reliability, smooth clamping action, and will not damage the tobacco leaves.

[0038] The conveying device 7 includes a drive roller 701, which is rotatably connected to the frame 1. A support frame 702 is fixedly connected to the base plate 401. A driven roller 703, which is rotatably connected to the support frame 702 and is correspondingly arranged to the drive roller 701. A conveyor belt 704 is sleeved on the drive roller 701 and the driven roller 703.

[0039] A collection box 705 is fixedly installed on the conveyor belt 704.

[0040] The frame 1 is equipped with a motor for driving the drive roller 701 to reciprocate.

[0041] The base plate 401 has a material passage hole 4011 that allows the conveyor belt 704 and the collection box 705 to pass through.

[0042] Compared to the traditional open conveyor belt that directly transports tobacco leaves, this design allows harvesters to place the picked tobacco leaves in the collection box 705 for transport, which avoids shaking, scattering, and damage of the tobacco leaves during the transport process, thus ensuring the integrity of the tobacco leaves during field operations.

[0043] During operation, two harvesters sit on the first-level harvesting chairs 302 to harvest tobacco plants on both sides. The harvested tobacco leaves are placed in the collection box 705 in front, and the collection box 705 is transported to the second level via the conveyor belt 704. After receiving the tobacco leaves, the harvesters on the second level complete the sorting and clamping of the tobacco leaves on the sorting table 5011. Finally, the tobacco leaf bunches are placed on the tobacco clamp rack 6. The whole process realizes the assembly line operation of "harvesting - conveying - sorting - racking", which significantly improves the efficiency of tobacco harvesting.

[0044] By integrating harvesting and sorting, the equipment significantly reduces the manual labor intensity during harvesting, avoids secondary damage during tobacco leaf handling, and ensures the quality of the tobacco leaves. At the same time, the equipment adopts a compact tracked chassis structure, which is suitable for inter-row operations in tobacco fields and has broad practicality and promotional value.

[0045] For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of this utility model, based on the teachings of this utility model, still fall within the protection scope of this utility model.
