Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a tobacco leaf picking and transporting vehicle. Background Art

[0002] Tobacco leaf harvesting and curing is a crucial process in flue-cured tobacco production, particularly leaf plucking. The quality of the leaves, and thus their quality and sales price, is crucial. Currently, the harvesting and topping and pruning phases are time-consuming, particularly in Dali, where tobacco cultivation is primarily located in mountainous and semi-mountainous areas. The varying sizes of tobacco fields make it difficult to operate with medium- and large-scale machinery. Therefore, topping and pruning tobacco grown in these areas are performed manually, leading to lengthy harvesting operations. Plucking involves workers sifting through the aisles between adjacent ridges, requiring them to bend over extensively and strenuously, which can lead to lumbar muscle strain. After picking, the leaves must be manually bundled and carried out of the aisle, a labor-intensive and time-consuming process. While some simple transport carts for tobacco harvesting are commercially available, these are limited by the capacity of the tobacco collection baskets, making it difficult to adjust the capacity according to actual harvesting requirements.

DETAILED DESCRIPTION

[0015] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0016] like Figure 1-3As shown, the utility model provides a tobacco leaf picking and transport vehicle, comprising a frame 1, a lifting mechanism and a carrying mechanism, wherein both sides of the bottom of the frame 1 are provided with a walking mechanism, a support seat 2 is provided on one side of the frame 1, and a lithium battery for providing a power source for the walking mechanism is provided in the support seat 2, and the lifting mechanism is provided on the other side of the frame 1, and the carrying mechanism is lifted and lowered by the lifting mechanism, and the carrying mechanism comprises a carrying frame 3, a slide plate 4 is slidingly provided in the carrying frame 3, expansion plates 5 are provided on both sides of the carrying frame 3, and a driving mechanism for driving the expansion plates 5 to extend and retract is provided at the bottom of the carrying frame 3, and the top of the support seat 2 is rotatably connected to a seat 13 through a rotating shaft 12, and a shaft sleeve is fixed to the support seat 2 by a bolt, and the shaft sleeve is connected to the rotating shaft 12 through a bearing, so that the seat 13 on the top of the rotating shaft 12 can rotate.

[0017] like Figure 1-3 As shown, first put the strapping tape on the slide plate 4, the operator sits on the seat 13, and adjusts the height of the carrying frame 3 by the lifting mechanism as needed. The staff sits on the vehicle and prunes or picks the tobacco leaves on both sides of the aisle, puts the pruned or picked tobacco leaves on the strapping tape on the slide plate 4, and bundles the tobacco leaves or pruning with the strapping tape. When the tobacco leaves on the strapping tape reach a certain amount, push the slide plate 4 toward one end of the carrying frame 3, and then put the strapping tape on the other end of the carrying frame 3, and continue to put the picked tobacco leaves or pruning on the strapping tape. The forks are placed on the packing belt and tied up, and the expansion plate 5 is extended by the driving mechanism to increase the capacity of the load-bearing frame 3, and the tobacco leaves in the load-bearing frame 3 are transported out by the walking mechanism. Compared with manual forking or picking and transportation, the operation time is greatly shortened and the labor intensity of the operators is reduced; due to the narrow aisle, the U-turn of the transport vehicle may easily cause damage to the tobacco leaves, so the seat 13 is rotatably installed on the support seat 2. When it is necessary to go back, it is only necessary to adjust the direction of the seat 13 and control the walking mechanism to move in the opposite direction.

[0018] The walking mechanism includes a crawler belt 6, driving wheels 7 arranged at both ends of the crawler belt 6, and a driving motor 8 that drives the driving wheels 7 to rotate. A plurality of driven wheels 9 are arranged between the two driving wheels 7.

[0019] As shown in the figure, the drive motor 8 is installed at both ends of the frame 1, the drive wheels 7 are rotatably installed on the frame 1 and are located on both sides of the drive motor 8, and the driven wheels 9 are rotatably installed on the frame 1 through the mounting frame. The drive motor 8 has a double-head output structure, and the drive motor 8 drives the two drive wheels 7 at one end of the crawler 6 to rotate. In this embodiment, two drive motors 8 are used to drive four drive wheels 7 to rotate, ensuring that the drive mechanism can provide sufficiently large power when used in the field.

[0020] The lifting mechanism includes a scissor-type lifting frame 10 and a hydraulic rod 11 for driving the scissor-type lifting frame 10 to extend and retract. An upper bunk is fixedly connected to the rotating shaft 12 and located below the seat 13. A foot pedal 14 is provided on the upper bunk to control the extension and retraction of the hydraulic rod 11. The foot pedal 14 facilitates the control of the lifting and lowering of the hydraulic rod 11.

[0021] like Figure 1 As shown, the scissor-type lifting frame 10 is convenient to retract and extend, so that the height of the carrying frame 3 can be adjusted according to actual conditions during use. During operation, the scissor-type lifting frame 10 is used more frequently, so a foot pedal 14 is provided to control the lifting of the carrying frame 3.

[0022] The expansion plate 5 is slidably mounted on the outside of the carrying frame 3. The driving mechanism includes a connecting rod 15 rotatably mounted on the top of the scissor-type lifting frame 10. Slide grooves 16 are provided on both side walls of the carrying frame 3. A slider 17 is slidably mounted in the slide groove 16. One end of the slider 17 is connected to the expansion plate 5. The other end of the slider 17 is threadedly connected to a screw rod 18. One end of the screw rod 18 passes through the bottom of the carrying frame 3 and is connected to a first bevel gear 19. The connecting rod 15 is provided with a second bevel gear 20 that meshes with the first bevel gear 19. One end of the connecting rod 15 is connected to a handwheel 21, and a handle 22 is fixed to the handwheel 21.

[0023] like Figure 2 and 3 As shown, the expansion plate 5 is slidably mounted on the outer surface of the carrying frame 3. The hand wheel 21 is rotated by the handle 22. Under the action of the connecting rod 15, the first bevel gear 19 and the second bevel gear 20, the hand wheel 21 drives the screw rod 18 to rotate, so that the slider 17 slides in the slide groove 16, driving the expansion plate 5 to extend and retract. When the expansion plate 5 moves upward, the capacity of the carrying frame 3 can be increased.

[0024] A parasol is provided on one side of the support base 2.

[0025] like Figure 1 As shown, the parasol can prevent workers from being exposed to the sun and improve the comfort of the working environment.

[0026] Principle of use: When pruned or picked tobacco leaves, the worker sits on the seat 13, controls the hydraulic rod 1 to control the scissor lift 10, adjusts the height of the carrying frame 3, so that the worker can pack in the carrying frame 3, puts the strapping tape on the slide 4, and then drives the walking mechanism to walk in the tobacco aisle. The worker sits and pruned or picked tobacco leaves on both sides of the aisle. The pruned or picked tobacco leaves are placed on the strapping tape and packed and tied. When the number of tobacco leaves on the slide 4 reaches a certain amount, the slide 4 will be pushed to move toward the inside of the carrying frame 3. The tobacco leaves push the inside of the carrying frame 3, and then the packing bags are laid in the carrying frame 3 to continue packing the picked tobacco leaves. During the packing process, in order to facilitate the workers to sit and pack, the height of the carrying frame 3 can be lowered by controlling the foot pedal 14 according to the stacking height of the carrying frame 3. If the amount picked is large, the expansion plate 5 can be driven to extend out of the carrying frame 3 by shaking the handle 22 to increase the capacity of the carrying frame 3. After picking, the seat 13 is rotated to the back, and the drive motor 8 rotates in the opposite direction to make the walking mechanism move back and transport the picked tobacco leaves out of the field.
