Abstract
Description
Technical Field
[0001] This application relates to the field of tea planting machinery technology, and in particular to a drone-based pruning device for tea tree side branches. Background Technology
[0002] Pruning the lateral branches of tea trees is an important technical measure in tea garden management. By pruning the lateral branches of tea trees, the growth direction and shape of the tea trees can be controlled, so that the tea trees form a more neat and open crown, promoting the growth and development of tea buds and leaves. At the same time, it can remove old, diseased and pest-infested branches in a timely manner, reduce nutrient consumption, and promote the sprouting of new and strong branches. It can also prevent the plants from becoming too dense, ensure good ventilation in the tea garden, and reduce the environment for the breeding of diseases and pests. It can also maintain appropriate row spacing for tea trees, which facilitates management operations such as fertilization, weeding, disease and pest control, and tea picking.
[0003] Currently, the pruning of tea tree lateral branches is usually done manually using hedge trimmers. However, this method is not only inefficient but also physically demanding for workers. To improve pruning efficiency and reduce labor intensity, related technologies have developed semi-automated tea tree pruning equipment to replace manual pruning. For example, invention application CN109417933A discloses a tea garden pruning device for tea cultivation. This device consists of two side plates, a motor, a cutting blade, and moving wheels. The motor is mounted on the two side plates, the cutting blade is connected to the motor, and the moving wheels are mounted on the two side plates. When pruning tea trees, the moving wheels are placed on the ground of the tea garden, and the two side plates are positioned on either side of the tea tree. The motor drives the cutting blade to rotate, pruning the tea tree.
[0004] However, the aforementioned tea garden pruning device can only move on the ground via wheels. Therefore, when operating in tea gardens with complex terrain such as mountains and hills, it may be limited by the terrain. For example, encountering steep slopes, narrow roads, or other difficult-to-access terrain can easily damage the machine or affect the pruning effect. Furthermore, it requires manual pushing or driving, which is relatively slow. When encountering tea trees with small spacing or irregular layouts, operation is restricted, resulting in low pruning efficiency, high workload, and a high risk factor (such as bee stings and snake bites). In addition, the operator of the tea garden pruning device is located inside the tea garden, and their field of vision is easily obstructed by tea trees and the surrounding environment, making it difficult to fully observe the pruning situation of the entire tea garden, potentially leading to omissions or uneven pruning. Utility Model Content
[0005] The purpose of this application is to provide a drone-based tea tree lateral branch pruning device to solve the problems of poor terrain adaptability, low operating efficiency, and limited field of vision caused by the fact that tea garden pruning devices in the related technology can only move on the ground by means of wheels.
[0006] The technical solution of the unmanned aerial vehicle (UAV) pruning device for tea tree lateral branches provided in this application is as follows:
[0007] A drone-based tea tree lateral branch pruning device includes a drone and also includes:
[0008] The main frame is detachably mounted on the UAV via connectors.
[0009] The trimming blades are provided in two sets, with the two sets of trimming blades spaced apart on the main frame;
[0010] A pruning drive unit is mounted on the main frame and connected to two sets of pruning blades to drive the pruning blades to prune the side branches of the tea tree.
[0011] Optionally, a remote controller is also included. The trimming drive includes a first actuator, which is mounted on the main frame and connected to the trimming blade. The first actuator is a motor or a gasoline engine, and the remote controller is used to electronically control the motor or gasoline engine.
[0012] Optionally, a width adjustment mechanism is also included, which is connected to the two sets of trimming blades and is used to adjust the width of the distance between the two sets of trimming blades according to the requirements of the tea shop.
[0013] Optionally, it also includes a suspension frame and a vertical adjustment component. The suspension frame is telescopically connected to the main frame. The main frame is provided with a telescopic column for vertically guiding the suspension frame. The connecting component is provided on the suspension frame. The vertical adjustment component is used to adjust the distance between the main frame and the trimmer and the UAV according to the terrain.
[0014] Optionally, it also includes a spacing adjustment component, which includes a slider and a lateral drive component. The connecting component is a clamp. There are two sets of sliders, which are mounted on the main frame. The lateral drive component is used to adjust the spacing between the two sets of sliders. The clamps are respectively mounted on the sliders and are used for detachable connection with the landing gear of the UAV.
[0015] Optionally, it also includes a slide table, which is provided in two sets and the two sets of slide tables are mounted on the main frame. The width adjustment mechanism is used to adjust the distance between the two sets of slide tables, and the two sets of trimming blades are respectively mounted on the two sets of slide tables.
[0016] Optionally, the trimming drive further includes a rotating drum and an intermediate shaft. The rotating drum is rotatably mounted on the main frame. The first actuator is located in the middle of the main frame and connected to the rotating drum. The intermediate shaft is rotatably mounted on the slide table. The intermediate shaft is provided with a transmission rod that is slidably inserted into the rotating drum. The intermediate shaft is connected to the trimming tool.
[0017] Optionally, it also includes a stop frame, on which a crossbeam is provided and a limiting groove is provided. The main frame can be placed unsupported in the limiting groove of the stop frame via the crossbeam.
[0018] In summary, this application includes at least the following beneficial technical effects:
[0019] 1. The width adjustment mechanism allows for adjustment of the distance between the two sets of pruning blades according to the tea row requirements. Adjusting the pruning width based on the tea row better adapts to the natural growth characteristics of the tea trees, avoiding over-pruning or under-pruning, helping the tea trees maintain good growth, promoting the sprouting and growth of new shoots, and ensuring tea yield and quality. Properly adjusting the pruning width maintains suitable spacing between tea trees, ensuring good ventilation in the tea garden and reducing the likelihood of pests and diseases. Adjusting the pruning width according to the tea row results in a more neat and standardized arrangement of tea trees, facilitating various management operations in the tea garden, such as fertilization, watering, and harvesting. It also makes walking and operating in the tea garden more convenient for staff, improving work efficiency, reducing labor intensity, and promoting mechanized operations, further enhancing the modernization level of tea garden management.
[0020] 2. The suspension frame is telescopically connected to the main frame, and the main frame is equipped with telescopic columns for vertical guidance of the suspension frame. This allows the distance between the pruning blades and the drone to be adjusted according to the terrain. Adjusting the distance between the pruning blades and the drone ensures that the pruning blades remain relatively stable near the tea trees at different heights, reducing swaying and swinging. This allows the cutting edge of the pruning blades to be closer to the surface of the tea trees, ensuring a smooth and consistent pruning. Tea trees in different terrains have different canopy shapes and foliage distributions. Taller tea trees may have long, upward-reaching branches, while shorter tea trees may have branches closer to the ground. By adjusting the distance between the pruning blades and the drone, the pruning blades can be flexibly positioned according to the specific shape and foliage distribution of the tea trees, avoiding potential collisions and protecting both the tea trees and the equipment.
[0021] 3. The first actuator can be an electric motor or a gasoline engine, which can be electronically controlled via a remote control. Operators only need to operate it from the ground using a remote control or intelligent system, eliminating the need for prolonged walking within the tea garden and reducing labor intensity. Furthermore, since the drone operates in the air, operators can clearly observe the overall condition of the tea garden through the display screen of the ground control terminal, facilitating timely detection and adjustments to ensure uniform and complete pruning.
[0022] 3. By carrying two sets of pruning blades on a drone, the drone flies above the tea garden and uses a pruning drive to prune the side branches of the tea trees. This allows it to move flexibly through tea gardens with various complex terrains, easily reaching areas that are difficult for manual labor or ground machinery to access for pruning, without being restricted by terrain conditions.
[0023] 4. Drones can be pre-programmed with flight paths to quickly fly over tea gardens and perform pruning. They operate quickly and can complete large-scale tea tree pruning in a short time. This is especially true for large, contiguous tea gardens, where the efficiency advantage is even more obvious. This solves the problems of low efficiency, high labor intensity, and high risk (such as bee stings and snake bites) caused by traditional manual pruning.
[0024] 5. The spacing between the clamps on the two sets of sliders can be adjusted by the spacing adjustment component, so that the main frame can be mounted on landing gear of different sizes, thus adapting to the installation needs of different models of UAVs. Attached Figure Description

[0045] The following is in conjunction with the appendix Figure 1 -Appendix Figure 12 This application will be described in further detail below.
[0046] Example 1
[0047] This embodiment discloses a drone-based device for pruning tea tree side branches.
[0048] A tea tree lateral branch pruning drone device includes a drone 10, a main frame 20, pruning blades 30, a pruning drive component 40, a spacing adjustment component 50, a width adjustment mechanism 60, an angle adjustment mechanism 70, a housing 80, a slide table 90, a landing frame 100, a control module, a communication module, a remote controller, and connectors.
[0049] Reference Figures 1 to 4 The main frame 20 is detachably mounted on the UAV 10 via a connector and a spacing adjustment assembly 50. In an optional embodiment, the structure of the spacing adjustment assembly 50 and the connector, as well as their connection relationship with the main frame 20 and the UAV 10, are as follows: The spacing adjustment assembly 50 includes a slider 51 and a lateral drive component. The connector is a clamp. There are two sets of sliders 51, which are mounted on the main frame 20. The lateral drive component is used to adjust the spacing between the two sets of sliders 51. The clamps are mounted on the sliders 51 and are used to detachably connect to the landing gear 11 of the UAV 10.
[0050] More specifically, the specific structure of the transverse drive component is as follows: the transverse drive component includes a lead screw 52, a guide post 21 is provided on the main frame 20, a slider 51 is slidably disposed on the guide post 21, a screw sleeve 511 is fixedly disposed on the slider 51, and the lead screw 52 is rotatably disposed on the main frame 20 and screwed to the screw sleeve 511.
[0051] More specifically, the specific structure of the clamp is as follows: The clamp includes a first clamping plate 53, a second clamping plate 54, and a fastener 55. The first clamping plate 53 is fixed on the slider 51, and the second clamping plate 54 is detachably connected to the first clamping plate 53 through the fastener 55. The first clamping plate 53 and the second clamping plate 54 are used to clamp the outside of the landing gear 11 of the UAV 10. The fastener 55 can be a bolt or nut. The cross-sectional shape of the first clamping plate 53 is V-shaped, and the cross-sectional shape of the second clamping plate 54 is arc-shaped.
[0052] Rotating the lead screw 52 can move the slider 51 along the guide post 21 to adjust the distance between the two sets of sliders 51 and the clamps on the sliders 51, thereby accommodating landing gear 11 of different sizes. At the same time, since the cross-sectional shape of the first clamping plate 53 is V-shaped and the cross-sectional shape of the second clamping plate 54 is arc-shaped, the first clamping plate 53 and the landing gear 11 are always in two linear contacts, and the second clamping plate 54 and the landing gear 11 are always in one linear contact, thus accommodating landing gear 11 of different diameters, and thus allowing the main frame 20 to be mounted on different types of UAVs 10.
[0053] Reference Figures 5 to 8 The width adjustment mechanism 60 is connected to two sets of trimming blades 30 and is used to adjust the width of the distance between the two sets of trimming blades 30 according to the requirements of the tea shop. In an optional embodiment, the width adjustment mechanism 60 and the two sets of trimming blades 30 can be connected in the following way:
[0054] Two sets of slide tables 90 are provided, and guide rails 23 are provided on the main frame 20. The two sets of slide tables 90 are slidably mounted on the guide rails 23 of the main frame 20. The width adjustment mechanism 60 is used to adjust the distance between the two sets of slide tables 90. More specifically, the specific structure of the width adjustment mechanism 60 and its specific connection relationship with the slide tables 90 are as follows: The width adjustment mechanism 60 includes a second actuator 61, a coupling 62, a rotating shaft 63, and a transmission shaft 64. The coupling 62, transmission shaft 64, and rotating shaft 63 are rotatably mounted on the main frame 20. The second actuator 61 is fixed in the middle of the main frame 20 and is connected to the coupling 62 through a second bevel gear pair 65. The second actuator 61 can be an electric motor. By placing the second actuator 61 in the middle of the main frame 20, the weight distribution on the main frame 20 can be kept balanced. The drive shaft 64 is connected to the coupling 62 via the third bevel gear pair 66. The rotating shaft 63 is provided with an adjusting gear 631 and a worm gear 632. The slide table 90 is provided with a rack 91 that meshes with the adjusting gear 631. The drive shaft 64 is provided with a worm 641 that meshes with the worm gear 632.
[0055] Reference Figures 6 to 9The trimming blades 30 are provided in two sets, and the two sets of trimming blades 30 are respectively spaced on two sets of slides 90 on the main frame 20. In an optional embodiment, the specific structure of the trimming blades 30 and their specific connection relationship with the slides 90 are as follows: the trimming blades 30 include blades 31, toothed discs 32 and connecting rods 33. The housing 80 is hinged to the slides 90 through a first pivot 81. The trimming blades 30 are provided on the housing 80. More specifically, the housing 80 is provided with two spaced-apart side plates 82. The blades 31 are provided with two blades, which are located between the two side plates 82. The sides of the two blades 31 are in contact with each other, and the blades 31 are provided with cutting teeth 311. The gear disk 32 is rotatably mounted inside the housing 80 via the central shaft 321. Eccentric wheels 34 are respectively provided on both sides of the gear disk 32. One end of the connecting rod 33 is sleeved on the outside of the eccentric wheel 34 via the bearing 35. The other end of the connecting rod 33 is hinged to the blade 31 via the pin 312. The blade 31 is provided with a strip groove 313. A limiting rod 83 is fixed between the two side plates 82. The limiting rod 83 passes through the strip groove 313 of the two blades 31.
[0056] The width adjustment mechanism 60 can adjust the distance between the two sets of pruning blades 30, thereby adapting to the needs of pruning tea trees of different widths.
[0057] Reference Figure 5 and Figure 6 An angle adjustment mechanism 70 is mounted on the slide table 90 and is used to drive the housing 80 to rotate about the axis of the hinge between the housing 80 and the slide table 90, i.e., the axis of the first pivot 81. In an optional embodiment, the specific structure of the angle adjustment mechanism 70, and its specific connection relationship with the slide table 90 and the housing 80, are as follows:
[0058] The angle adjustment mechanism 70 includes a cylinder 71 and screws 72. Threaded bushings 73 are fixed to both ends of the cylinder 71. Two screws 72 are provided, each screwed to one of the threaded bushings 73 at the other end of the cylinder 71. One screw 72 is hinged to the slide table 90 via a second pivot 721, and the other screw 72 is hinged to the housing 80 via a third pivot 722. The cylinder 71 has a screw-in hole 711. Inserting a wrench or other tool into the screw-in hole 711 allows the cylinder 71 to rotate. When the cylinder 71 rotates, the interaction between the threaded bushings 73 and the screws 72 causes the two screws 72 to move axially in opposite or opposite directions, thereby causing the housing 80 to rotate around the axis of the first pivot 81. This adjusts the angle of the trimming blade 31 of the trimming cutter 30 to meet the trimming needs of different shapes.
[0059] Reference Figures 3 to 8 , Figure 10 and Figure 11The pruning drive unit 40 is mounted on the main frame 20 and connected to two sets of pruning blades 30 to drive the pruning blades 30 to prune the side branches of the tea tree. In an optional embodiment, the specific structure of the pruning drive unit 40 and its specific connection relationship with the pruning blades 30 are as follows:
[0060] The trimming drive unit 40 includes a first actuator 41, a rotating drum 42, an intermediate shaft 43, an input shaft 45, and a telescopic shaft. The first actuator 41 is fixed in the middle of the main frame 20. Placing the first actuator 41 in the middle of the main frame 20 can maintain the balance of weight distribution on the main frame 20. The first actuator 41 is connected to the trimming cutter 30. More specifically, the rotating drum 42 is rotatably mounted on the main frame 20, and the first actuator 41 is connected to the rotating drum 42 through a first bevel gear pair 44. The intermediate shaft 43 is rotatably mounted on the slide table 90. The intermediate shaft 43 is provided with a transmission rod 431 that is slidably inserted into the rotating drum 42. The cross-sectional shape of the transmission rod 431 can be set to a regular hexagon.
[0061] The intermediate shaft 43 is connected to the trimming tool 30 in the following manner:
[0062] The input shaft 45 is rotatably mounted on the housing 80 and connected to the trimming tool 30. More specifically, the input shaft 45 is provided with an input gear 451, which meshes with the gear plate 32 of the trimming tool 30.
[0063] The two ends of the telescopic shaft are connected to the intermediate shaft 43 and the input shaft 45 respectively through universal joints 46. More specifically, the telescopic shaft includes a sleeve 47 and a telescopic rod 48. The telescopic rod 48 is slidably inserted into the sleeve 47. The cross-sectional shape of the telescopic rod 48 can be set to a regular hexagon. The sleeve 47 and the telescopic rod 48 are connected to the intermediate shaft 43 and the input shaft 45 respectively through universal joints 46.
[0064] The first actuator 41 can be powered by a motor or gasoline engine, and the remote controller is used to electronically control the first actuator 41, such as the motor or gasoline engine. In an optional embodiment, the connection relationship between the remote controller and the first actuator 41 is as follows:
[0065] The control module and communication module are mounted on the main frame 20. The control module is electrically connected to the first actuator 41 of the trimming drive 40 and the second actuator 61 of the width adjustment mechanism 60. The communication module is electrically connected to the control module, and the remote controller is wirelessly connected to the communication module.
[0066] The first actuator 41 and the second actuator 61 are electrically connected to the battery 110. The battery 110 can supply power to the first actuator 41 and the second actuator 61. The battery 110 can be installed on the drone 10 or on the main frame 20.
[0067] The main frame 20 is provided with a crossbeam 22, and the parking frame 100 is provided with a limiting groove 101. The main frame 20 can be placed on the limiting groove 101 of the parking frame 100 by the crossbeam 22, so that the tea tree side branch drone pruning device of this embodiment can be parked on the parking frame 100 before and after the pruning operation.
[0068] The implementation principle of the UAV pruning device for tea tree side branches in this embodiment is as follows: During pruning operations, the UAV 10 is flown above the tea garden, with two sets of pruning blades 30 positioned on both sides of the tea tree. A control signal is then sent from the remote controller to the communication module, which in turn transmits the control signal to the control module, which then activates the first actuator 41. The first actuator 41 then drives the rotating drum 42 to rotate, which in turn drives the input shaft 45 to rotate via the transmission rod 431, intermediate shaft 43, universal joint 46, sleeve 47, and telescopic rod 48. The input gear 451 then drives the gear plate 32 to rotate, which in turn drives the two blades 31 to reciprocate via the eccentric wheel 34 and connecting rod 33, pruning the side branches of the tea tree using the teeth 311 on the two blades 31.
[0069] When the pruning width needs to be adjusted, the second actuator 61 drives the coupling 62 to rotate, and then the transmission shaft 64 drives the worm gear 641 to rotate. Next, the worm gear 641 drives the worm wheel 632, the rotating shaft 63 and the adjusting gear 631 to rotate. Under the interaction of the adjusting gear 631 and the rack 91, the slide table 90 moves relative to the main frame 20, thereby adjusting the distance between the two sets of pruning blades 30, and thus adapting to the needs of pruning tea trees of different widths.

[0071] This embodiment discloses a drone-based device for pruning tea tree side branches.
[0072] Reference Figure 12 The difference between the tea tree side branch drone pruning device in this embodiment and that in embodiment 1 is that it also includes a suspension frame 120 and a vertical adjustment component 130. The suspension frame 120 is telescopically connected to the main frame 20. The main frame 20 is provided with a telescopic column 24 for vertically guiding the suspension frame 120. The telescopic column 24 is slidably inserted through the suspension frame 120, and the connecting component is provided on the suspension frame 120.
[0073] The vertical adjustment component 130 is used to adjust the distance between the main frame 20 and the trimmer 30 and the drone 10 according to the terrain. More specifically, the vertical adjustment component 130 can be an electric push rod, the main body of which is fixed to the suspension frame 120, and the push-pull rod of the electric push rod is fixed to the main frame 20. By controlling the extension and retraction of the push-pull rod of the electric push rod, the distance between the main frame 20 and the trimmer 30 and the drone 10 can be adjusted, thereby adjusting the distance between the trimmer 30 and the drone 10 to a suitable value to adapt to the trimming needs of different terrains.
[0074] In an optional embodiment, the specific connection relationship between the connector and the suspension frame 120 is as follows: the connector adopts the clamp in embodiment 1 and is connected to the suspension frame 120 through the spacing adjustment component 50 in embodiment 1.
