[0051] The present invention will be further described below with reference to the accompanying drawings:

[0052] This embodiment:

[0053] Please see Figure 1-8 In this embodiment: a tobacco leaf field transport device includes: a tobacco leaf receiving assembly, a height adjustment structure, and a moving assembly.

[0054] In this embodiment, the tobacco leaf receiving assembly includes a tobacco leaf placement box 23 for placing tobacco leaves.

[0055] In this embodiment, the surface of the tobacco leaf placement box 23 has three notches. The notches on both sides are used to place tobacco leaves, and the notch in the middle is used to reserve space for the movement of the tobacco leaf placement box 23 so that it will not be blocked by the top plate.

[0056] The height adjustment structure is located below the tobacco leaf placement box 23 and is connected to the tobacco leaf placement box 23. The height adjustment structure includes four sets of extension columns 4, one end of each set of extension columns 4 is fixedly connected to the tobacco leaf placement box 23, and is used to adjust the height of the tobacco leaf placement box 23.

[0057] In this embodiment, by operating the height adjustment structure, the height adjustment structure can push the tobacco leaf placement box 23 to move vertically upward, so that the tobacco leaf placement box 23 can pass over the tobacco leaves without scraping them, thus avoiding the tobacco leaves from breaking and becoming inconvenient to use.

[0058] The moving component is located below and connected to the height adjustment structure, and can move the tobacco leaf receiving component through the height adjustment structure.

[0059] In this embodiment, the moving component is used to move the tobacco leaf receiving component so that the user can directly place the collected tobacco leaves into the tobacco leaf receiving component.

[0060] like Figure 4 and Figure 5 As shown, the height adjustment structure also includes: two sets of moving rods 5, two sets of rotating plates 6, two sets of worm gears 7, worm 8, and a first motor 9.

[0061] Each set of movable rods 5 is fixedly connected to two sets of extension columns 4 at both ends.

[0062] In this embodiment, by moving the moving rod 5 vertically, the two sets of extension columns 4 connected to it can be moved synchronously; the connecting line of these two sets of extension columns 4 is perpendicular to the moving direction of the moving component.

[0063] Each set of rotating plates 6 has a groove at one end, so that the moving rod 5 is placed in the groove and the rotating plate 6 is slidably connected to the moving rod 5 through the groove.

[0064] In this embodiment, by rotating the rotating plate 6, the rotating plate 6 transmits a force biased towards the vertical direction to the moving rod 5 through the sliding between the sliding groove and the moving rod 5.

[0065] The shaft of each worm gear 7 is fixedly connected to the other end of the rotating plate 6.

[0066] In this embodiment, the worm gear 7 can drive the rotating plate 6 to rotate synchronously, so that the slide can make circular motion around the axis of the worm gear 7.

[0067] The worm 8 is positioned between two sets of worm gears 7 and is meshed with both sets of worm gears 7; the output end of the first motor 9 is fixedly connected to one end of the worm 8.

[0068] In this embodiment, the model of the first motor 9 is selected according to actual needs, as long as it meets the working conditions; the output end of the first motor 9 can drive the worm 8 to rotate, and the worm 8 can simultaneously drive two sets of worm wheels 7 to rotate in opposite directions.

[0069] When the height of the tobacco leaf placement box 23 needs to be adjusted, the first motor 9 is started. The output end of the first motor 9 drives the worm gear 8 to rotate. The worm gear 8 causes the two sets of worm wheels 7 to rotate in opposite directions. The worm wheels 7 simultaneously drive the rotating plate 6 to rotate. The rotating plate 6 slides between the sliding groove and the moving rod 5, so that the moving rod 5 is subjected to a force biased towards the vertical direction. Since the extension column 4 can only move vertically, it restricts the vertical movement of the moving rod 5. At the same time, the extension column 4 pushes the tobacco leaf placement box 23 to move, lifting the tobacco leaf placement box 23 so that the tobacco leaf placement box 23 can pass over the tobacco leaves without scraping them, avoiding breakage of the tobacco leaves, and facilitating use.

[0070] like Figure 2 and Figure 5 As shown, the moving assembly includes: four sets of support columns 1, two sets of wheel drive assemblies 2, and two sets of connecting plates 3.

[0071] Each set of support columns 1 has an inwardly recessed groove at one end, allowing the extension column 4 to slide and connect with the support column 1 through the groove; the other end of the support column 1 is equipped with a wheel and is rotatably connected to the wheel.

[0072] In this embodiment, the groove opened by the support column 1 can restrict the extension column 4 to move only vertically, so that the moving rod 5 will move vertically after being subjected to force; the support column 1 can also support the rotation of the wheel.

[0073] Each set of wheel drive components 2 is fixedly connected to two sets of support columns 1; the output end of the wheel drive component 2 is fixedly connected to the axle of the wheel.

[0074] In this embodiment, the wheel drive assembly 2 can be a combination of an electric motor and a gearbox, or a combination of an electric motor and a bevel gear set, as long as it can drive the wheel to rotate; at the same time, this wheel drive assembly 2 is existing technology, so its specific structure will not be described in detail.

[0075] Each set of connecting plates 3 is located between two sets of support columns 1 and is fixedly connected to the support columns 1.

[0076] In this embodiment, the connecting plate 3 can fix the two sets of support columns 1 on the same side together; the same side here means that the line connecting the two sets of support columns 1 is parallel to the direction of wheel movement.

[0077] When the device needs to be moved, the wheel drive assembly 2 is activated, which drives the wheels to rotate, thereby moving the entire device. The support column 1 supports the rotation of the wheels.

[0078] After the height adjustment is completed, the tobacco leaf placement box 23 is supported only by the sliding between the rotating plate 6 and the moving rod 5. As the amount of tobacco leaves increases, the burden between the rotating plate 6 and the moving rod 5 will increase, and in severe cases, the service life of the rotating plate 6 and the moving rod 5 will be reduced.

[0079] To address the aforementioned issues, this embodiment proposes an implementation method in which the tobacco field transport device further includes two sets of auxiliary support structures. Each set of auxiliary support structures is positioned directly above the connecting plate 3 and is used to support the tobacco leaf placement box 23.

[0080] like Figure 6 As shown, each set of auxiliary support structures includes: two sets of wedges 10, two sets of support blocks 11, two sets of moving parts 12, threaded rods 13, and handwheels 14.

[0081] Specifically, one end of each set of wedges 10 passes through the connecting plate 3 and is slidably connected to the connecting plate 3; the other end of the wedges 10 is fixedly connected to the lower end face of the tobacco leaf placement box 23; the surface of each set of support blocks 11 is in contact with the surface of the wedges 10.

[0082] In this embodiment, after the tobacco leaf placement box 23 is lifted, it will drive the wedge block 10 to move. At this time, the support block 11 is inserted under the wedge block 10 to support the wedge block 10. Since the contact surface between the support block 11 and the wedge block 10 is inclined and perpendicular to each other, the vertical force is changed into a horizontal force.

[0083] One side of each set of moving parts 12 is fixedly connected to the side of the support block 11 away from the wedge block 10; both ends of the threaded rod 13 pass through the two sets of moving parts 12 and are threadedly connected to the moving parts 12.

[0084] In this embodiment, the rotation of the threaded rod 13 causes the moving part 12 to move horizontally, and the moving part 12 pushes the support block 11 to insert below the wedge block 10 to support the wedge block 10. Both the threaded rod 13 and the moving part 12 are made of high-strength steel. At the same time, the thread depth of the threaded rod 13 is between 1cm and 3cm, which can bear the weight of the tobacco leaf placement box 23 and the tobacco leaves. The thread directions on both sides of the threaded rod 13 are opposite.

[0085] The handwheel 14 is sleeved on the outer middle of the threaded rod 13 and is fixedly connected to the threaded rod 13.

[0086] In this embodiment, the threaded rod 13 can be driven to rotate synchronously by rotating the handwheel 14.

[0087] When support is needed, the user turns the handwheel 14, which drives the threaded rod 13 to rotate synchronously. The threaded rod 13 causes the two sets of moving parts 12 to move outward at the same time. The moving parts 12 insert the support block 11 under the wedge block 10 and contact the wedge block 10 to support the wedge block 10, reduce the burden between the rotating plate 6 and the moving rod 5, and increase the service life of the rotating plate 6 and the moving rod 5.

[0088] like Figure 8As shown, the tobacco leaf receiving assembly of the tobacco leaf field transport device also includes: a tobacco leaf hanging rod 24; both ends of the tobacco leaf hanging rod 24 are fixedly connected to the tobacco leaf placement box 23.

[0089] like Figure 1 As shown, the tobacco field transport device also includes: a top plate 25; the top plate 25 is arranged parallel above the tobacco storage box 23.

[0090] Raising the tobacco leaf placement box 23 makes the process of placing tobacco leaves inconvenient.

[0091] To address the aforementioned issues, this embodiment proposes an implementation method in which the tobacco field transport device further includes a feeding structure; the feeding structure is disposed on both sides of the top plate 25 for feeding.

[0092] like Figure 3 and Figure 7 As shown, the feeding structure includes: a support plate 15, multiple sets of guide wheels 16, a cable 17, a winding wheel 18, a second motor 19, an electric push rod 21, and a feeding rod 22.

[0093] The bottom end of the support plate 15 is fixedly connected to the upper end face of the top plate 25; the axis of each set of guide wheels 16 is rotatably connected to the surface of the support plate 15.

[0094] In this embodiment, the support plate 15 can support the rotation of the guide wheel 16.

[0095] The surface of cable 17 is in contact with multiple sets of guide wheels 16.

[0096] In this embodiment, the direction of movement of the cable 17 can be controlled by the guide wheel 16.

[0097] The surface of the take-up reel 18 is fixedly connected to one end of the cable 17, so that the cable 17 can be wound around the take-up reel 18.

[0098] In this embodiment, when the winding wheel 18 rotates, the cable 17 is wound up and unwound.

[0099] The output end of the second motor 19 is fixedly connected to the shaft of the take-up reel 18.

[0100] In this embodiment, the second motor 19 has a self-locking capability. The model of the second motor 19 is selected according to actual needs, as long as it meets the working conditions. The output end of the second motor 19 can drive the winding wheel 18 to rotate.

[0101] The upper end of the electric push rod 21 is fixedly connected to the other end of the cable 17.

[0102] In this embodiment, when the cable 17 moves, it will drive the electric push rod 21 to move; the model of the electric push rod 21 is selected according to actual needs, as long as it meets the working conditions.

[0103] One end of the feeding rod 22 is fixedly connected to the output end of the electric push rod 21.

[0104] In this embodiment, the output end of the electric push rod 21 can push the feeding rod 22 to move horizontally.

[0105] During the feeding process, the bundled tobacco leaves are hung on the feeding rod 22 using hooks that resemble fishhooks. The second motor 19 is then activated, and its output drives the winding wheel 18 to rotate. The winding wheel 18 winds up the cable 17, causing the electric push rod 21 to move upwards. Simultaneously, the electric push rod 21 moves the feeding rod 22. Once the feeding rod 22 is slightly higher than the tobacco hanging rod 24, the electric push rod 21 is adjusted so that its output pushes the feeding rod 22, which in turn moves the tobacco leaves. As the tobacco leaves move, they come into contact with the tobacco hanging rod 24 and tilt slightly under its obstruction. Then, the feeding rod 22 is moved downwards, moving the tobacco leaves. When the feeding rod 22 is lower than the tobacco hanging rod 24, the hooks on the tobacco leaves are hooked onto the tobacco hanging rod 24, completing the feeding process and making the placement of the tobacco leaves more convenient.

[0106] like Figure 3 and Figure 7 As shown, the feeding structure also includes: four sets of limiting plates 26 and connecting parts 20.

[0107] Specifically, one end of each set of limiting plates 26 is fixedly connected to the support column 1, and the other end is fixedly connected to the top plate 25; one end of the connector 20 is fixedly connected to the side of the electric push rod 21; the other end of the connector 20 is provided with a slider, which is placed in the slide rail and is slidably connected to the limiting plate 26 through the slide rail.

[0108] In this embodiment, the sliding between the limiting plate 26 and the connecting member 20 can restrict the electric push rod 21 to move only vertically.

[0109] Working principle:

[0110] When using this tobacco field transport device, the device is moved to the side of the tobacco field, and the height of the tobacco leaf placement box 23 is adjusted according to the height of the plants. By starting the first motor 9, the output end of the first motor 9 drives the worm gear 8 to rotate. The worm gear 8 causes the two sets of worm wheels 7 to rotate in opposite directions. The worm wheels 7 simultaneously drive the rotating plate 6 to rotate. The rotating plate 6 slides between the sliding groove and the moving rod 5, so that the moving rod 5 is subjected to a force biased in the vertical direction. Since the extension column 4 can only move vertically, it restricts the vertical movement of the moving rod 5. At the same time, the extension column 4 pushes the tobacco leaf placement box 23 to move, lifting the tobacco leaf placement box 23 so that the tobacco leaf placement box 23 can pass over the tobacco leaves without scraping the tobacco leaves, avoiding the tobacco leaves from breaking, and facilitating use.

[0111] After adjustment, the user turns the handwheel 14, which drives the threaded rod 13 to rotate synchronously. The threaded rod 13 causes the two sets of moving parts 12 to move outward at the same time. The moving parts 12 insert the support block 11 under the wedge block 10 and contact the wedge block 10 to support the wedge block 10, reduce the burden between the rotating plate 6 and the moving rod 5, and increase the service life of the rotating plate 6 and the moving rod 5.

[0112] By activating the wheel drive assembly 2, the wheel drive assembly 2 can drive the wheel to rotate, thereby moving the entire device. The support column 1 will support the rotation of the wheel and move the device into the tobacco field.

[0113] Subsequently, the user hangs the bundled tobacco leaves on the feeding rod 22 using hooks shaped like fishhooks. At this point, the second motor 19 is activated, and its output drives the winding wheel 18 to rotate. The winding wheel 18 winds up the cable 17, causing the electric push rod 21 to move upwards. Simultaneously, the electric push rod 21 moves the feeding rod 22. After the feeding rod 22 moves slightly above the tobacco leaf hanging rod 24, the electric push rod 21 is adjusted so that its output pushes the feeding rod 22, which in turn moves the tobacco leaves. As the tobacco leaves move, they come into contact with the tobacco leaf hanging rod 24 and tilt slightly under its obstruction. Then, by moving the feeding rod 22 downwards, the tobacco leaves are moved. When the feeding rod 22 is below the tobacco leaf hanging rod 24, the hooks on the tobacco leaves are hooked onto the tobacco leaf hanging rod 24, completing the feeding process and making the placement of the tobacco leaves more convenient, thus completing the use of the device.

[0114] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
