Description

Technical Field

[0001] This utility model relates to the field of pesticide spraying technology, and more specifically, it relates to a drone spraying device for pesticides used to treat forest pests and diseases. Background Technology

[0002] In the field of forestry pest and disease control, drone spraying technology has become a core method for large-scale forest pest and disease control due to its advantages such as high flexibility, fast operation efficiency, and adaptability to complex terrain. Drone spraying devices, equipped with pesticide tanks and spraying systems, can accurately spray pesticides into the canopy and leaf gaps of trees, effectively improving pest and disease control coverage, reducing the intensity and safety risks of manual labor, and are particularly suitable for mountainous and hilly forest areas that are difficult for manual labor to access.

[0003] An existing drone spraying device for forest pests and diseases has been found to have the following issues during use:

[0004] 1. The existing disassembly process for medicine tanks is cumbersome. When it is necessary to replenish medicine, clean the medicine tank, or replace different types of medicine, it is necessary to loosen the bolts distributed around the tank one by one or disassemble multiple sets of clips. The operation process requires special tools.

[0005] 2. Furthermore, maintenance is time-consuming, bolts are prone to rust when exposed to the humid outdoor environment for a long time, and clips are prone to loosening after frequent use, further increasing the difficulty of disassembly, resulting in a longer interval between pesticide replacements and affecting the timeliness of pest and disease control. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] In view of the problems existing in the prior art, this utility model provides a drone spraying device for forest pest and disease pesticides, so as to solve the technical problems mentioned in the background art, such as the inability to quickly disassemble the pesticide tank and the long disassembly time.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution: a drone spraying device for forest pest and disease pesticides, comprising a drone body, a base at the bottom of the drone body, support frames on both sides of the base, an installation block at the bottom of the base, a fixing mechanism on the outer side of the installation block, an annular plate on the outer side of the installation block via the fixing mechanism, the top of the annular plate being in close contact with the bottom of the base, and an installation ring rotatably mounted on the bottom of the annular plate, a pesticide tank rotatably mounted on the inner bottom of the installation ring, an installation plate at the bottom of the pesticide tank, a pumping device at the top rear end of the installation plate, a spraying device at the bottom of the installation plate, auxiliary components on both sides of the bottom of the base, and the two sides of the bottom of the base being connected to the outer side of the installation ring via the auxiliary components.

[0010] The present invention is further configured such that the fixing mechanism includes two sets of positioning blocks, and slots are evenly provided at both ends of the outer side of the mounting block. Positioning blocks are provided in the slots of both sets of mounting blocks, and a first clamping plate is provided at the other end of each set of positioning blocks. The bottom of each set of first clamping plates slides tightly against the top of the liquid tank. A first screw is provided at one end of each set of first clamping plates, and a threaded cylinder is threadedly connected to the other end of each set of first screws. The other end of each set of threaded cylinders is rotatably connected to one end of the inner side of an annular plate. An adjustment component is provided on the inner side of the mounting ring, and the inner side of the mounting ring is connected to the outer side of the two sets of threaded cylinders through the adjustment component. The locking and engaging of the positioning blocks with the slots replaces traditional bolt fastening, enabling rapid fixing and disassembly of the liquid tank. This solves the problem of cumbersome operation caused by the reliance on bolts in existing devices, and is especially suitable for field operations without specialized tools. The transmission structure of the first screw and the threaded cylinder can finely adjust the clamping force of the positioning blocks, ensuring a stable connection while avoiding excessive compression that could damage components. The two sets of first clamping plates are symmetrically distributed, which makes the force on the mounting block balanced, reduces structural vibration during the flight of the UAV, and improves the overall stability of the device.

[0011] The present invention is further configured such that the adjusting component includes an annular block, an annular block is provided on the inner side of the mounting ring, toothed blocks are evenly provided on the inner side of the annular block, and connecting gears are provided on the outer sides of both sets of threaded cylinders, with the bottom of both sets of connecting gears meshing with the toothed blocks; the meshing transmission of the annular block and the connecting gears realizes the synchronous adjustment of the two sets of threaded cylinders, ensuring that the two sets of positioning blocks simultaneously engage or disengage from the slots. The gear transmission has high synchronization accuracy, making the alignment of the positioning blocks and the slots more precise, avoiding loosening due to misalignment, enhancing the reliability of the device in flight vibration environment, and the adjustment process does not require separate operation of the two sets of threaded cylinders, simplifying the disassembly and assembly steps, and further shortening the replacement time of the liquid tank.

[0012] The present invention is further configured such that the auxiliary component includes two sets of second clamping plates, an annular groove is provided on the outer side of the mounting ring, fixing blocks are provided on both sides of the bottom of the base, both sets of fixing blocks are provided with threaded holes, and a second screw is threadedly connected to the threaded holes of both sets of fixing blocks. A second clamping plate is provided at one opposite end of each set of second screws, and a locking block is provided at one opposite end of each set of second clamping plates. The locking blocks are engaged with one end of the annular groove of the mounting ring, and the tops of the two sets of second clamping plates slide tightly against the bottom of the base. A rotating handle is provided at the other end of each set of second screws. The cooperation between the locking blocks and the annular groove enhances the connection strength between the mounting ring and the base, ensuring the stability of the liquid tank during the flight of the UAV. The cooperation between the second screw and the rotating handle makes operation easier, and the tightness adjustment of the auxiliary fixation can be completed without special tools, meeting the convenience requirements of field operations. The two sets of second clamping plates are symmetrically distributed, so that the mounting ring is subjected to balanced force, reducing the frictional resistance during rotation adjustment.

[0013] The present invention is further configured such that sliding grooves are provided on both sides of the top of the liquid tank, and first guide blocks are slidably arranged in both sets of sliding grooves of the liquid tank. The bottom of the two sets of first clamping plates is respectively connected to the top of one set of first guide blocks. The sliding cooperation between the first guide blocks and the sliding grooves provides stable guidance for the first clamping plates, which solves the problem of tilting caused by uneven force when the first clamping plates move, ensures the alignment accuracy between the positioning block and the slot, and improves the reliability of the fixing mechanism.

[0014] The present invention is further configured such that sliding grooves are provided on both sides of the bottom of the base, and second guide blocks are slidably disposed in the two sets of base sliding grooves. The tops of the two sets of second clamping plates are respectively connected to the bottom of one set of second guide blocks. The cooperation between the second guide blocks and the sliding grooves provides rigid guidance for the second clamping plates, preventing the second clamping plates from shifting or tilting when moving, ensuring that the locking blocks are accurately locked into the annular grooves, solving the problem of inaccurate alignment during auxiliary fixing, and enhancing the fixing effect of the auxiliary components.

[0015] The present invention is further configured such that supports are provided on both the front and rear sides of the mounting plate, and mounting frames are provided at the bottom of the four sets of supports, and the bottom of the mounting frames and the bottom of the support frames are on the same plane; the mounting frames and the support frames cooperate to form a stable support structure, which solves the problem that the liquid tank and spraying device are easily damaged by contact with the ground when the drone is parked, protects the precision components such as the nozzles of the spraying device, and reduces maintenance costs.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a drone spraying device for forest pest and disease pesticides, which has the following beneficial effects:

[0018] 1. The fixed mechanism and auxiliary components work together to replace the traditional bolt connection, enabling quick assembly and disassembly of the liquid tank. This solves the problem of cumbersome disassembly of existing devices, significantly shortens the time for replenishing the agent and cleaning the tank, and meets the needs of high-frequency operations in the field forest area. The overall structure integrates the functions of liquid storage, pumping, and spraying. The connection with the main body of the drone is stable and reliable, reducing component shaking during flight, reducing the risk of agent spillage, and improving operational safety.

[0019] 2. The locking mechanism between the positioning block and the slot replaces traditional bolt fastening, enabling rapid fixing and disassembly of the liquid tank. This solves the problem of cumbersome operation caused by the reliance on bolts in existing devices, making it particularly suitable for field operations without specialized tools. The transmission structure of the first screw and threaded cylinder allows for fine-tuning of the positioning block's clamping force, ensuring a stable connection while preventing excessive compression that could damage components. The two sets of first clamping plates are symmetrically distributed, ensuring balanced force distribution on the mounting blocks, reducing structural vibration during drone flight, and improving the overall stability of the device.

[0029] Please see Figure 1-5 A drone spraying device for forest pests and diseases includes a drone body 1, a base 2 at the bottom of the drone body 1, support frames 3 on both sides of the base 2, an installation block 4 at the bottom of the base 2, a fixing mechanism on the outside of the installation block 4, an annular plate 5 on the outside of the installation block 4 through the fixing mechanism, the top of the annular plate 5 and the bottom of the base 2 being in close contact, and an installation ring 6 being rotatably mounted at the bottom of the annular plate 5, a liquid tank 7 being rotatably mounted on the bottom inner side of the installation ring 6, an installation plate 8 at the bottom of the liquid tank 7, a pumping device 9 at the top rear end of the installation plate 8, a spraying device 10 at the bottom of the installation plate 8, and auxiliary components on both sides of the bottom of the base 2, which are connected to the outside of the installation ring 6 through the auxiliary components.

[0030] In this embodiment, during operation, the pumping device 9 delivers the pesticide in the pesticide tank 7 to the spraying device 10 to achieve the spraying of pesticides for forest pests and diseases. When it is necessary to disassemble the pesticide tank 7, first contact the auxiliary component to limit the mounting ring 6, then rotate the mounting ring 6. By rotating the mounting ring 6, the fixing mechanism is adjusted until the mounting ring 6 is disengaged from the outside of the mounting block 4, and the disassembly of the pesticide tank 7 can be completed.

[0031] More specifically, by rotating the rotating handle 24 at the other end of the second screw 17, the second screw 17 rotates along the threaded hole of the fixing block 16, pushing the second clamping plate 19 to slide until the two sets of second clamping plates 19 respectively drive the locking block 18 to disengage from the annular groove on the outside of the mounting ring 6, thus releasing the fixation of the mounting ring 6.

[0032] Please see Figure 1 and Figure 4As one embodiment of the fixing mechanism: the fixing mechanism includes two sets of positioning blocks 11. The outer ends of the mounting blocks 4 are evenly provided with slots. The two sets of mounting blocks 4 are each provided with a positioning block 11 in the slots. The other end of the two sets of positioning blocks 11 is provided with a first clamping plate 12. The bottom of the two sets of first clamping plates 12 is slidably attached to the top of the medicine tank 7. One end of the two sets of first clamping plates 12 is provided with a first screw 13. The other end of the two sets of first screws 13 is threadedly connected to a threaded cylinder 14. The other end of the two sets of threaded cylinders 14 is rotatably connected to one end of the inner side of the annular plate 5. An adjustment component is provided on the inner side of the mounting ring 6. The inner side of the mounting ring 6 is connected to the outer side of the two sets of threaded cylinders 14 through the adjustment component.

[0033] Specifically, the worker rotates the installation ring 6, and starts to rotate the threaded cylinder 14 by adjusting the component. The rotation of the threaded cylinder 14 drives the first screw 13 to push the first clamping plate 12, so that the positioning block 11 is inserted into the slot on the outside of the installation block 4. The first clamping plate 12 is fixed by adhering to the top of the medicine tank 7.

[0034] Please refer to Figures 2-4 As a further embodiment of the fixing mechanism: the adjusting component includes an annular block 15, an annular block 15 is provided on the inner side of the mounting ring 6, toothed blocks 25 are evenly provided on the inner side of the annular block 15, and connecting gears 26 are provided on the outer sides of the two sets of threaded cylinders 14, and the bottom of the two sets of connecting gears 26 are engaged with the toothed blocks 25.

[0035] Specifically, rotating the mounting ring 6 causes the inner annular block 15 to rotate. The toothed block 25 of the annular block 15 meshes with the connecting gear 26 on the outer side of the threaded cylinder 14, driving the two sets of threaded cylinders 14 to rotate synchronously. This, in turn, causes the first clamping plate 12 and the positioning block 11 to move synchronously, thus enabling the positioning block 11 to engage or disengage from the slot.

[0036] In summary, the overall equipment is in use (or running):

[0037] During the spraying operation, the pumping device 9 on the mounting plate 8 at the bottom of the liquid tank 7 is activated, pressurizing the agent in the liquid tank 7 and delivering it to the spraying device 10 at the bottom of the mounting plate 8. The spraying device 10 atomizes and sprays the agent to complete the spraying of pesticides for forest pests and diseases.

[0038] When it is necessary to disassemble the medicine tank 7 for medicine replenishment or cleaning, first rotate the rotating handle 24 at the other end of the two sets of second screws 17. The second screws 17 rotate in the opposite direction along the threaded hole of the fixing block 16 at the bottom of the base 2, driving the second clamping plate 19 to move away from the mounting ring 6. The locking block 18 at the opposite end of the second clamping plate 19 gradually disengages from the annular groove on the outside of the mounting ring 6, releasing the auxiliary components from restricting the mounting ring 6. At this time, the second guide block 21 at the top of the second clamping plate 19 slides synchronously along the sliding groove at the bottom of the base 2 to ensure smooth operation.

[0039] Then, the mounting ring 6 is rotated, and the annular block 15 on the inner side of the mounting ring 6 rotates together. The toothed block 25 on the inner side of the annular block 15 meshes with the connecting gear 26 on the outer side of the two sets of threaded cylinders 14, driving the threaded cylinders 14 to rotate synchronously in the opposite direction. The threaded cylinders 14 are threadedly engaged with the first screw 13, pulling the first clamping plate 12 to move away from the mounting block 4. The first guide block 20 at the bottom of the first clamping plate 12 slides along the sliding groove at the top of the medicine tank 7 to ensure a stable movement trajectory. Finally, the positioning block 11 at the other end of the first clamping plate 12 is completely disengaged from the slot on the outer side of the mounting block 4, releasing the connection constraint of the fixing mechanism between the mounting block 4 and the annular plate 5, thus completing the disassembly of the medicine tank 7.

[0040] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
