Description

Technical Field

[0001] This invention belongs to the field of tobacco curing operation technology, and in particular to a comprehensive operation machine for tobacco curing in mountainous areas. Background Technology

[0002] The integrated management machine for flue-cured tobacco in mountainous areas pressurizes herbicides through a pressurization system, forming high-pressure atomized droplets through nozzles. This atomization method can expand the coverage area of ​​the herbicide, allowing the droplets to adhere evenly to the surface of weed leaves, thus improving the utilization rate of the herbicide. It is widely used in flue-cured tobacco field management operations.

[0003] In existing publicly available literature, patent publication number CN201467856U discloses a tall-legged tobacco sprayer. This technology features wheels beneath the tall legs, allowing direct access between rows for spraying, saving significant amounts of field access and effectively improving land utilization. The machine's operating height can be adjusted according to the tobacco's growth height, accommodating field operations throughout the entire tobacco growth cycle. The machine's spraying uniformity and operating speed are far superior to manual spraying. Furthermore, the machine can be used to transport harvested tobacco leaves after removing the spraying device, making it multi-functional. However, the existing technology still has the following problems: In the integrated management of weed control in flue-cured tobacco fields in mountainous areas, the tobacco leaves have a multi-tiered structure with outer and inner layers. Under the influence of gravity, they tend to fall. When herbicides are sprayed, the falling leaves form a barrier layer, making it difficult for the herbicide to accurately reach the weeds. Instead, a large amount of herbicide adheres to the tobacco leaves. This contact not only wastes the herbicide but also causes excessive pesticide residues on the surface of the tobacco leaves, which reduces the weed control effect and increases the risk of pesticide contamination in the tobacco leaves. Summary of the Invention

[0004] Purpose of the invention: To provide a comprehensive management machine for flue-cured tobacco fields in mountainous areas, which can ensure that the spraying of pesticides achieves the purpose of weed control while avoiding the problem of excessive pesticide residue on tobacco leaves. Technical solution

[0005] A comprehensive management machine for flue-cured tobacco fields in mountainous areas includes a handheld part for holding the machine, a stepped protective part located at one end of the handheld part, and a spraying part. The stepped protection unit includes a positioning block and a lifting mechanism located around the positioning block; The spraying unit includes at least two sets of spray pipes and a rotating mechanism for driving the spray pipes to rotate. The two sets of spray pipes are symmetrically arranged on both sides of the outer side of the positioning block. When the main branch of the flue-cured tobacco enters the positioning block from one end opening, the lifting mechanism moves to gather the flue-cured tobacco leaves upwards from the outside to the inside, so that a spraying protection space is formed between the stepped protection part and the spraying part. The rotating mechanism drives the spraying pipe to spray the weeds near the flue-cured tobacco plant in the spraying protection space.

[0006] In some possible embodiments, the step protection part includes a support assembly connected to the handheld part, a first lifting member, a second lifting member, a lifting power member, and a protruding column disposed on the support assembly; The support assembly includes a bracket, a support plate, and a groove column. The support plate is fixed on the bracket, one end of the support plate is connected to one end of the groove column, and the other end of the groove column is connected to the positioning block.

[0007] In a further embodiment, both the first lifting member and the second lifting member are slidably connected to the protruding post; The lifting power component is used to drive the second lifting component to move up and down along the height direction of the convex column; The first lifting member and the second lifting member are connected by a rope, and the second lifting member drives the first lifting member to move up and down along the height direction of the convex column through the rope.

[0008] In a further embodiment, the first lifting member includes an inner bracket and a lower sleeve fixed to one end of the inner bracket; The second lifting component includes an outer bracket and an upper sleeve fixed to one end of the outer bracket; Both the inner bracket and the outer bracket are annular structures, and the inner diameter of the outer bracket is larger than the outer diameter of the inner bracket.

[0009] In a further embodiment, the lifting power component includes a first electric cylinder, the output end of which is connected to the top end of a connecting rod, and the bottom end of the connecting rod is connected to the upper sleeve.

[0010] In a further embodiment, the spray pipe includes a narrow pipe and two oblique side pipes respectively connected and fixed at both ends of the narrow pipe, and the outer walls of the narrow pipe and the oblique side pipes are fixedly connected with a plurality of nozzles.

[0011] In a further embodiment, the rotating mechanism includes a second electric cylinder installed in the slot column, the output end of the second electric cylinder is fixed with a frame bar, and at least two sliding columns are slidably connected in the frame bar; The two sliding columns are symmetrically distributed within the frame strip, with both ends of the sliding columns extending out of the frame strip and connected to the rotating groove plate, which is connected to the spraying pipe.

[0012] In a further embodiment, a bushing is rotatably fitted onto the narrow tube, and the bushing is fixed to the outer wall of the positioning block.

[0013] In a further embodiment, the spraying unit further includes a container for holding the herbicide and a pressurizing component disposed on the container. The container is disposed on the support plate and connected to two sets of spraying pipes via a hose. The pressurizing component delivers pressurized air into the container.

[0014] In a further embodiment, the handheld part includes a grip bar, one end of which is fixedly connected to the bracket; The outer wall of the grip is equipped with a controller, which is electrically connected to the first electric cylinder and the second electric cylinder; the machine can be conveniently held and used by the hand.

[0015] The beneficial effects of this invention are as follows: This invention utilizes a stepped protection section composed of a first lifting mechanism and a second lifting mechanism. Activating the first electric cylinder pushes the connecting rod upwards, causing the upper sleeve to move along the outer wall of the convex column. This, in turn, causes the outer support frame to lift the outer leaves of the mountain flue-cured tobacco. Simultaneously, the upper sleeve moves the top of the rope to a vertical position, creating a stepped gap between the outer and inner supports. The rope then moves the lower sleeve upwards, which in turn moves the inner support frame to lift the inner leaves of the mountain flue-cured tobacco. A stepped, unobstructed protective spraying space is formed below the lower sleeve and the convex column. Spraying in this space allows the herbicide to precisely reach the weeds, avoiding excessive adhesion to the tobacco leaves, reducing waste and pesticide residues. This integrated operation technology combines weeding and protection functions, significantly improving weeding efficiency and greatly reducing the risk of pesticide contamination in tobacco leaves.

[0016] This invention activates the second electric cylinder via a controller, pushing the frame bar upwards. The frame bar drives the sliding column to rotate the rotating trough plate clockwise, while another rotating trough plate rotates counterclockwise. Consequently, the narrow tube, the oblique side tube, and multiple nozzles rotate clockwise. The two sets of oblique side tubes and the narrow tube rotate along the shape of the field ridge on both sides of the positioning block. The two sides of the positioning block can provide blocking protection to prevent herbicide from contaminating the main branches of flue-cured tobacco in the mountainous area. The herbicide can accurately reach the weeds, which not only greatly improves the weeding effect but also significantly reduces the risk of excessive pesticide residues in tobacco leaves.

Detailed Implementation

[0026] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid obscuring the invention.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Example 1: This example describes a comprehensive field management machine for flue-cured tobacco in mountainous areas, as disclosed in this example. (Refer to...) Figure 1 The work machine includes a handheld part for holding the work machine, a stepped protective part located at one end of the handheld part, and a spraying part; The step protection part includes a positioning block 2 and a lifting mechanism disposed around the positioning block 2; the step protection part includes a support assembly connected to the handheld part, a first lifting member, a second lifting member, a lifting power member and a protruding column 6 disposed on the support assembly.

[0029] The support assembly includes a bracket 25, a support plate 11, and a groove column 1. The support plate 11 is fixed on the bracket 25. One end of the support plate 11 is connected to one end of the groove column 1, and the other end of the groove column 1 is connected to the positioning block 2.

[0030] like Figure 2and Figure 3 As shown, both the first and second lifting members are slidably connected to the protruding post 6, and both the lifting power member and the protruding post 6 are mounted on the support plate 11; the lifting power member is used to drive the second lifting member to move up and down along the height direction of the protruding post 6; as shown Figure 4 As shown, the first lifting member and the second lifting member are connected by a rope 7, and the second lifting member drives the first lifting member to move up and down along the height direction of the convex column 6 through the rope 7.

[0031] like Figure 3 As shown, the first lifting component includes an inner bracket 3 and a lower sleeve 5 fixed to one end of the inner bracket 3. Specifically, the lower sleeve 5 can be fixed to the lower surface of one end of the inner bracket 3 to cooperate with the upper sleeve 8. The lower sleeve 5 moves away from the groove column 1 under the lifting of the rope 7. The second lifting component includes an outer bracket 4 and an upper sleeve 8 fixed to one end of the outer bracket 4. The groove of the inner bracket 3 bypasses the main branches of the mountain flue-cured tobacco, and the inner bracket 3 is located below the inner leaves of the mountain flue-cured tobacco. The groove of the outer bracket 4 bypasses the main branches of the mountain flue-cured tobacco, and the outer bracket 4 is located below the outer leaves of the mountain flue-cured tobacco. Both the inner bracket 3 and the outer bracket 4 are annular structures, and the inner wall diameter of the outer bracket 4 is larger than the outer wall diameter of the inner bracket 3. The upper sleeve 8, the lower sleeve 5, and the groove column 1 are arranged in parallel from top to bottom, and the two ends of the rope 7 are respectively connected to the upper sleeve 8 and the lower sleeve 5.

[0032] Specifically, the bottom end of the protruding post 6 is fixed to the support plate 11, and the top end is provided with a limiting block. The upper sleeve 8 and the lower sleeve 5 are slidably sleeved on the protruding post 6. The protruding post 6 is located between the connecting plate and the first electric cylinder 10. The connecting plate is as follows: Figure 4 The shape shown is an inverted "L". This arrangement allows the protruding post 6 to be located below the horizontal part of the connecting plate, and the horizontal part of the connecting plate can be connected to the output end of the first electric cylinder 10. The bottom end of the vertical part of the connecting plate can be fixed on the upper sleeve 8.

[0033] The lifting power component includes a first electric cylinder 10, such as... Figure 4 As shown, the output end of the first electric cylinder 10 is connected to the top end of the connecting rod 9, and the bottom end of the connecting rod 9 is connected to the upper sleeve 8; the first electric cylinder 10 is mounted on the support plate 11.

[0034] The spraying unit includes at least two sets of spray pipes and a rotating mechanism for driving the spray pipes to rotate. The two sets of spray pipes are symmetrically arranged on both sides of the outer side of the positioning block 2. When the main branches of the flue-cured tobacco enter the positioning block 2 through one end opening, the lifting mechanism moves to gather the flue-cured tobacco leaves upwards from the outside to the inside, forming a spraying protection space between the stepped protection section and the spraying section. The rotating mechanism drives the spraying pipe to spray the weeds near the flue-cured tobacco plants in the spraying protection space. The stepped protection section gathers and protects the tobacco leaves inside. At this time, there are no tobacco leaves or main branches between the outside of the stepped protection section and the spraying pipe, which is the spraying protection space. Therefore, when the spraying pipe sprays, it will only spray in this space and will not spray on the tobacco leaves in the stepped protection section. The two sets of spraying pipes are located on both sides of the opening, which ensures the normal layout and spraying of the spraying pipes without affecting the flue-cured tobacco plants entering the positioning block 2 from the opening.

[0035] The implementation principle of this embodiment is as follows: When using the working machine, the output end of the first electric cylinder 10 pushes the connecting rod 9 upward, the upper sleeve 8 begins to move along the outer wall of the convex column 6, and the outer bracket 4 begins to lift the outer leaves of the mountain flue-cured tobacco, causing the multiple circumferentially distributed outer leaves of the mountain flue-cured tobacco to begin to move upward and lift. At the same time, the upper sleeve 8 drives the top of the rope 7 to move upward until the rope 7 is in a vertical state. The rope 7 drives the lower sleeve 5 to move upward, and the lower sleeve 5 moves upward along the outer wall of the convex column 6, causing the inner bracket 3 to begin to lift the inner leaves of the mountain flue-cured tobacco, causing the multiple circumferentially distributed inner leaves of the mountain flue-cured tobacco to begin to move upward and lift. In this way, the vertical distance between the outer bracket 4 and the inner bracket 3 becomes larger, and a stepped distance is formed between the outer bracket 4 and the inner bracket 3. A large unobstructed space in a stepped state is generated below the inner bracket 3 and the outer bracket 4. This structural design allows herbicides to precisely target weeds, preventing excessive herbicide adhesion to tobacco leaves. This not only significantly reduces herbicide waste but also avoids excessive herbicide residue on the surface of tobacco leaves.

[0036] Example 2: Based on Example 1, this example discloses a comprehensive field management machine for flue-cured tobacco in mountainous areas, such as... Figure 5 As shown, the spraying pipe includes a narrow pipe 16 and two oblique side pipes 18 that are respectively connected and fixed at both ends of the narrow pipe 16. The outer walls of the narrow pipe 16 and the oblique side pipes 18 are fixedly connected to a number of nozzles 19. Preferably, the flexible hose 20 is connected to the side pipe near the side of the container 21. The pesticide in the container 21 is input into the narrow pipe 16 and the oblique side pipes through the flexible hose 20, and then sprayed out by the nozzles 19 onto the weeds around the tobacco plants.

[0037] like Figure 6As shown, the rotating mechanism includes a second electric cylinder 12 installed inside the slot column 1. A frame bar 13 is fixed to the output end of the second electric cylinder 12. At least two sliding columns 14 are slidably connected within the frame bar 13. The two sliding columns 14 are symmetrically distributed within the frame bar 13, with both ends extending out of the frame bar 13 and connected to a rotating slot plate 15. The rotating slot plate 15 is connected to the spray pipe. The frame bar 13 is U-shaped, and a gap is provided between the end of the frame bar 13 and the inner wall of the rotating slot plate 15, allowing the rotating slot plate 15 to rotate with the movement of the sliding columns 14 when the frame bar 13 rises and falls. (Refer to...) Figure 5 To facilitate the coordinated arrangement of the second electric cylinder 12, the frame bar 13, and the two rotating slot plates 15, and to meet the positional matching between the rotating slot plate 15 and the spray pipe, a groove is provided on the slot column 1. The second electric cylinder 12 is fixed below the slot column 1, and its output end extends through the slot column 1 into the groove and connects to the frame bar 13. The shape of the groove matches the frame bar 13. When the output end of the second electric cylinder 12 extends and retracts in the groove, the frame bar 13 can also move in and out of the groove accordingly.

[0038] Specifically, the grooving plate 15 is fixedly connected to the narrow tube 16, such as... Figure 5 As shown, the two ends of the sliding column 14 extend from the frame bar 13 and are connected to the two corresponding side walls of the rotating trough plate 15. The cross-sections of the two rotating trough plates 15 are respectively in the shape of "[" and "]", which partially surround the outside of the frame bar 13 on the left and right. As the second electric cylinder 12 extends and retracts, the frame bar 13 is driven to move up and down, thereby causing the sliding column 14 to slide up and down in the sliding groove, and then rotating the rotating trough plate 15 and the spraying pipe connected to it. The sliding range of the sliding column 14 in the frame bar 13 is limited, which also limits the rotation angle of the rotating trough plate 15. To a certain extent, it can also limit the rotation spraying range of the spraying pipe. The rotation spraying range angle is 0-60°, avoiding the rotation angle being too large or too small, which would cause the liquid to be sprayed onto the adjacent flue-cured tobacco plants or not be able to be sprayed onto the nearby weeds.

[0039] To make the rotation of the spray pipe more stable, a bushing 17 is rotatably fitted on the narrow pipe 16. The bushing 17 is fixed on the outer wall of the positioning block 2. The bushing 17 further strengthens the connection between the narrow pipe 16 and the positioning block 2, and does not affect the rotation of the narrow pipe 16 and the side-sloping pipe with the rotating groove plate 15. Preferably, the bushing 17 is located in the middle of the narrow pipe 16.

[0040] In order to ensure the supply of pesticides during the spraying process and improve the spraying effect, such as Figure 7As shown, the spraying unit also includes a container 21 for holding herbicides and a pressurizing component disposed on the container 21. The container 21 is disposed on the support plate 11 and connected to two sets of spraying pipes through a hose 20. The pressurizing component delivers pressurized air into the container 21. Furthermore, the container 21 is mounted on the bracket 25. The pressurization assembly includes a pressurizing fan 23 and a pressurizing pipe 22. The pressurizing pipe 22 is fixedly connected to the upper surface of the container 21. The pressurizing fan 23 is installed at one end of the pressurizing pipe 22 and is used to pressurize the inside of the pressurizing pipe 22. A threaded cap 28 is provided on one side of the pressurizing pipe 22, and the threaded cap 28 is threadedly connected to the container 21. A battery 24 is installed on the outer wall of the container 21. The battery 24 supplies power to the pressurizing fan 23. After the threaded cap 28 is opened, the herbicide can be poured into the container 21. Then, the threaded cap 28 is placed on the container 21 to seal it.

[0041] The implementation principle of this embodiment is as follows: The booster fan 23 is activated to pressurize the booster pipe 22. The herbicide is poured from the container 21 into the hose 20, and then enters the inclined side pipe 18 through the hose 20. It is then atomized and sprayed through the narrow pipe 16 and multiple nozzles 19 on the inclined side pipe 18. The second electric cylinder 12 pushes the frame bar 13 upward, and the sliding column 14 slides within the frame bar 13. The frame bar 13 moves upward along the inner wall of the two rotating trough plates 15. The rotating trough plates 15 rotate clockwise, while the other rotating trough plate 15 rotates counterclockwise. The narrow pipe 16 rotates clockwise along the inner wall of the bushing 17. Both the narrow pipe 16 and the inclined side pipe 18 drive multiple nozzles 19 to rotate clockwise, so that the two sets of inclined side pipes 18 and narrow pipes 16 begin to rotate along the shape of the field ridge on both sides of the positioning block 2, ensuring that the herbicide is accurately sprayed under the protective environment on both sides of the positioning block 2.

[0042] Example 3: Based on Example 1, this example discloses a comprehensive field management machine for flue-cured tobacco in mountainous areas, such as... Figure 8 As shown, the handheld part includes a grip 26, one end of which is fixedly connected to the bracket 25; a controller 27 is provided on the outer wall of the grip 26, and the controller 27 is electrically connected to the first electric cylinder 10 and the second electric cylinder 12. The bottom cross-sectional area of ​​the grip 26 is larger than the top cross-sectional area of ​​the bracket 25, and the bottom end of the grip 26 is parallel to the top end of the bracket 25.

[0043] Specifically, the controller 27 is also electrically connected to the booster fan 23. During drug supply protection, the battery 24 supplies power to the booster fan 23, and the controller 27 starts the booster fan 23, thus boosting the pressure of the booster pipe 22. The booster pipe 22 then delivers the boosted air into the container 21, through the container 21 into the hose 20, and through the hose 20 into the inclined pipe 18. The air then enters the bushing 17 through the inclined pipe 18 and is atomized and sprayed through the narrow pipe 16 and multiple nozzles 19 on the inclined pipe 18.

[0044] The implementation principle of this embodiment is as follows: by holding the handle 26 on the outer wall with one hand and the bracket 25 on the outer wall with the other hand, the handle 26 and the bracket 25 move synchronously. At the same time, the controller 27 can activate the relevant electrical components, making operation convenient.
