[0034] It should be noted that the following detailed descriptions are all illustrative and are intended to provide further explanations of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those of ordinary skill in the technical field to which the present invention belongs.

[0035] Example 1:

[0036] This example provides a self-propelled tobacco topping and bud inhibiting device, as Figures 1-4 shown, including a frame 7, a self-propelled chassis 1, a reaping hook 31, a topping device 3, a bud inhibiting device 5, a plant protection device 6, and a collection device 4. The self-propelled chassis 1 is installed at the bottom of the frame 7, enabling the entire device to travel along the ridge body; the reaping hook 31, the topping device 3, the bud inhibiting device 5, the plant protection device 6, and the collection device 4 are all installed on the frame 7. In the running direction of the device, the front side of the frame 7 is installed with the topping device 3, the reaping hook 31, and the bud inhibiting device 5 through a lifting device 2, and the lifting device 2 is also installed on the rear side of the frame 7. The plant protection device 6 is connected to the lifting device 2 on the rear side of the frame 7.

[0037] The self-propelled chassis 1 in this example adopts a crawler structure and can run stably along the ridge body. A ridge body guiding device 11 is installed inside the self-propelled chassis 1. As Figure 6 shown, the ridge body guiding device 11 includes an angle sensor 14, an angle adjusting device 16, and a guide roller 15. The guide roller 15 is connected to the angle adjusting device 16, and the angle sensor 14 is installed on the angle adjusting device 16. Moreover, the angle sensor 14, the angle adjusting device 16, and the drive motor in the self-propelled chassis 1 are all connected to the controller. The guide roller 15 is in contact with the ridge surface. The angle sensor 14 is used to identify the traveling angle. When the direction of the ridge body changes, the angle sensor 14 detects the change signal and controls the drive motor on the side where the direction changes to reduce the speed, adjusting the traveling direction of the device to achieve self-propelled travel along the ridge.

[0038] The angle adjustment device 16 can be implemented using an existing structure. In this embodiment, the angle adjustment device 16 includes a first adjustment rod 11 and a second adjustment rod 12. One end of the first adjustment rod 11 and the second adjustment rod 12 are hinged together. The other end of the second adjustment rod 12 is connected to the guide roller 15. The first adjustment rod 11 is connected to an adjustment power source (such as a motor). Under the driving action of the adjustment power, the angle between the first adjustment rod 11 and the second adjustment rod 12 is changed, so as to ensure that the guide roller 15 remains in contact with the ridge surface.

[0039] The frame 7 is installed at the middle position of the self-propelled chassis 1. Two sets of lifting devices 2 are symmetrically arranged relative to the frame 7, making the overall frame of the equipment symmetric and increasing the stability of the equipment. In this embodiment, the lifting device 2 includes a bracket 23, a lifting power mechanism 22, and two sets of parallelogram linkages 21. As Figure 1 shown, the bracket 23 includes a cross beam and a column installed at the middle position of the cross beam. Reinforcing ribs are connected between the column and the cross beam. One set of parallelogram linkages 21 is connected to each end of the cross beam. One end of the parallelogram linkage 21 is fixed to the cross beam, and the other end is fixed to the frame 7. The two sets of parallelogram linkages 21, the cross beam, and the frame 7 form a quadrilateral structure, increasing the stability of the structure.

[0040] The two sets of parallelogram linkages 21 are connected by another cross beam. The fixed end of the lifting power mechanism 22 is connected to this cross beam. The output end of the lifting power mechanism 22 is hinged to the top of the column of the bracket 23. Under the driving action of the lifting power mechanism 22, the bracket 23 and the installation structure thereon rise or fall. The lifting power mechanism 22 can be implemented using an electric push rod, a cylinder, a hydraulic cylinder, a linear motor, etc.

[0041] The topping device 3 is inclinedly installed on the cross beam of the bracket 23. The topping device 3 includes a topping motor 32, a topping moving knife 33, and a topping fixed knife 34. The output end of the topping motor 32 faces downward and is installed at a certain angle relative to the cross beam of the bracket 23. The motor shaft of the topping motor 32 is connected to the topping moving knife 33 and is connected to the middle position of the topping moving knife 33. When the topping motor 32 rotates, the topping moving knife 33 forms a circular cutting trajectory.

[0042] As Figure 5 shown, the axis of the motor shaft is perpendicular to the topping moving knife 33. The topping moving knife 33 forms a certain angle with the horizontal plane. During the rotation of the topping moving knife 33, an inclined cut can be formed at the top of the tobacco plant. Compared with a horizontal cut, it is convenient for rainwater drainage, reduces the probability of cut infection, and ensures the quality of the tobacco plant.

[0043] In order to keep the tobacco plant stationary during the topping process, a topping fixed knife 34 is arranged below the topping moving knife 33. The topping fixed knife 34 is connected to the rear end of the lifter 31 and cooperates with the lifter 31 to limit the tobacco plant. As Figure 1 and Figure 3As shown, the tobacco supporter 31 is provided with a guide area and a straightening area from front to back in sequence. The guide area is a trumpet-mouth structure, and the tobacco plants are gradually straightened through the inclined side walls and enter the rear straightening area. Since the straightening area can only ensure that the tobacco plants are in an upright state, there will still be a problem of force deviation of the tobacco plants during the topping process. Therefore, a topping fixed knife 34 is installed on one side of the straightening area to narrow the regional gap.

[0044] In order to collect the fireworks after cutting off while topping, the present embodiment is provided with a collecting device 4, which includes a guide piece 35 installed on the upper side of the topping movable knife 33 and a collecting frame 41 fixed to one side of the frame 7. The guide piece 35 rotates with the topping movable knife 33 to throw out the cut fireworks, and a collecting bag is installed in the collecting frame 41 to receive the thrown fireworks. Figure 1 and Figure 2 As shown, the guide pieces 35 are symmetrically distributed relative to the topping motor 32, and the guide pieces 35 are perpendicular to the topping moving knife 33. In this embodiment, the collection bag is detachably connected to the collection frame 41, for example, by being tied to the collection frame 41 with a rope, or by being snapped to the collection frame 41, etc., so that another collection bag can be easily replaced when the collection bag is full of fireworks.

[0045] The bud inhibitor device 5 of this embodiment applies the bud inhibitor to the inclined cut of the tobacco plant in a smearing manner. The bud inhibitor device 5 includes a bud inhibitor box 53, a roller brush and a travel switch 52. The bud inhibitor box 53 is used to make the bud inhibitor flow to the roller brush when the tobacco stem touches the travel switch 52. The roller brush is used to evenly apply the bud inhibitor to the tobacco stem.

[0046] like Figures 1-4 As shown, the sprout inhibitor box 53 is fixed to the frame 7, which is filled with the sprout inhibitor, and a pipe is led out from the sprout inhibitor box 53, and the pipe is installed with a control valve; the outlet end of the pipe corresponds to the roller brush. The travel switch 52 is installed at the rear end of the straw support 31, and its installation position is slightly lower than the topping moving knife 33, so that the tobacco plants after topping can contact the travel switch 52 during the forward movement of the equipment. The travel switch 52 and the control valve are both connected to the controller. After the controller receives the start signal of the travel switch 52, it opens the control valve, and the sprout inhibitor can flow out of the sprout inhibitor box 53, and then be applied by the roller brush.

[0047] In order to achieve uniform and multi-directional application of the bud inhibitor, the roller brush of this embodiment includes a transverse roller brush 51 and a vertical roller brush 54. The transverse roller brush 51 is used to apply the top of the tobacco plant, and the vertical roller brush 54 is used to apply the side of the tobacco plant. Therefore, two groups of vertical roller brushes 54 are arranged, and the two groups of vertical roller brushes 54 are symmetrically distributed relative to the transverse roller brush 51.

[0048] The plant protection device 6 can be flexibly adjusted by the lifting device 2 at the rear to meet different plant protection requirements; the plant protection device 6 includes a medicine tank 65 and a spray boom. The medicine tank 65 is installed on the upper side of the self-propelled chassis 1, and the liquid in the medicine tank 65 can be replaced according to specific plant protection requirements, and the liquid can be insecticide, herbicide, liquid fertilizer, etc.

[0049] In order to achieve multi-directional spraying of plant protection liquid (pesticide solution), the spray boom in this embodiment includes a horizontal spray boom 61 and a longitudinal spray boom 62. One horizontal spray boom 61 is provided on each of the left and right sides of the frame 7; the horizontal spray boom 61 is connected to the bracket 23 of the rear lifting device 2 through a telescopic cylinder 64. By changing the angle of the horizontal spray boom 61 through the telescopic cylinder 64, the spraying range can be increased. At the same time, one longitudinal spray boom 62 is connected to each end of the bracket 23. A plurality of nozzles 63 are evenly distributed on the transverse spray boom and the longitudinal spray boom 62 respectively. Each spray boom is of a hollow structure, and the spray boom is connected to the medicine tank 65 through a pipeline; through the cooperation of the above nozzles 63, the spraying range can be increased.

[0050] In this embodiment, the start and stop of the topping moving knife 33, the lifting adjustment of the front and rear lifting device 2, the telescopic operation of the horizontal spray boom 61, and the angle adjustment when the equipment moves along the ridge are all controlled by a remote controller, improving the operation safety. In the topping device 3, the topping moving knife 33 and the topping motor 32 are arranged at a certain angle, so that an inclined cut is formed at the top of the tobacco plant to avoid affecting the quality of the tobacco plant due to incision damage; at the same time, fireworks can be collected during topping, improving the continuity of the operation. The equipment in this embodiment is also equipped with a plant protection device 6, which can perform plant protection operations on tobacco plants according to requirements, further improving the operation efficiency.

[0055] (2) The device automatically travels along the ridge and starts to operate. The lifter 31 in front of the topping device 3 keeps the tobacco plants always upright and guides the tobacco plants into the topping area. The topping fixed knife 34 fixes the tobacco plants to ensure the stability and precise position of the tobacco plants; the topping moving knife 33 rotates under the drive of the topping motor 32 to cut off the top fireworks, forming an inclined cut at the top of the tobacco plant; at the same time, the cut fireworks enter the collection bag under the action of the guiding piece 35.

[0056] (3) As the device moves forward, the tobacco stalks that have been topped touch the travel switch 52, and the control valve connected to the bud inhibitor box 53 opens, and the bud inhibitor flows from the medicine box 65 to the roller brush, and the roller brush evenly coats the top and both sides of the tobacco stalks.

[0057] It should be noted that according to actual needs, the plant protection device 6 is started, and the liquid medicine is sprayed on the tobacco plants through the nozzle 63.
