Description

Technical Field

[0001] This utility model belongs to the field of agricultural drone technology, specifically relating to a chainsaw-based agricultural drone. Background Technology

[0002] With the development of modern agriculture and forestry, the requirements for the efficiency and safety of plant protection operations are becoming increasingly stringent. Traditional manual spraying of pesticides and pruning of branches are not only inefficient but also pose significant safety risks when operating at heights. To improve operational efficiency and ensure personnel safety, agricultural drone technology is gradually being widely adopted.

[0003] Current agricultural drone technology primarily utilizes drones equipped with pesticide spraying devices. These drones typically possess vertical takeoff and landing (VTOL) and hovering capabilities, and are operated via remote control or autonomous control systems. The spraying device includes a pesticide tank, a pesticide pump, and nozzles, capable of evenly spraying pesticides in a mist form onto crops or trees. Additionally, some drones are equipped with branch-pruning devices, such as robotic arms or simple cutting tools. During branch pruning, the resulting debris and fragments can damage the drone itself, especially the rotor, and also increase the safety risks for operators. This results in a lack of effective protective measures for both the drone and operators during spraying and pruning operations, particularly in the event of flying debris.

[0004] In view of this, we propose a chainsaw-based agricultural drone to solve the above problems. Utility Model Content

[0005] The present invention aims to solve the technical problem in the prior art where the debris and fragments generated by the drone during tree trimming may cause damage to the drone body, especially the rotor.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A chainsaw-equipped agricultural drone includes:

[0008] The drone itself has vertical take-off and landing and hovering functions and is operated via a remote controller or autonomous control system;

[0009] A pesticide spraying device is installed below the drone and is used to spray pesticides.

[0010] A circular chainsaw, with several equally spaced pieces, used for trimming tree branches;

[0011] A carbon fiber mesh protective cover is located below the drone and covers the outside of the circular chainsaw and pesticide spraying device, separating the drone body from the circular chainsaw and pesticide spraying device to prevent cutting debris from flying and damaging the propeller on the drone body.

[0012] The drone itself can fly stably in the air thanks to its built-in vertical takeoff and landing (VTOL) and hovering capabilities, achieved by adjusting the lift and torque generated by its propellers. The drone can be operated via remote control or an autonomous control system, allowing it to fly along preset routes or perform tasks according to operator instructions. The pesticide spraying device is located beneath the drone. When the drone flies to the target area, pesticides from the storage tank are pumped into the nozzles and evenly sprayed onto the crops. Circular chainsaws, evenly spaced beneath the drone and driven by motors, are used to prune branches; their speed and movement can be adjusted by the control system. A carbon fiber mesh protective cover, located beneath the drone, covers the circular chainsaws and pesticide spraying device to prevent any debris from damaging the drone's propellers or other components.

[0013] Preferably, the drone body has a mounting platform at its bottom, with two support feet fixedly connected to each side of the platform. The design of the mounting platform and support feet makes the drone more stable during operation, reduces swaying caused by external factors such as wind, and improves the accuracy of operations.

[0014] Preferably, the mounting platform has a mounting bracket at its bottom, on which the pesticide spraying device is mounted. The pesticide spraying device includes a storage tank and a nozzle inserted into the mounting bracket. The storage tank is connected to the nozzle via a pesticide liquid pipeline and a pesticide liquid pump. The design of the storage tank and nozzle on the mounting bracket makes pesticide spraying more convenient and also facilitates the replacement of different types of pesticides.

[0015] Preferably, a crossbar is provided between the two support legs, and an integrally formed mounting block is fixed to the top of the crossbar. The mounting block has a slot, into which a support limiting block, which is supported at the bottom of the storage tank and limits the movement of the outer side of the storage tank, is engaged and fixed. The design of the crossbar and mounting block between the support legs provides additional stability, while the support limiting block restricts the movement of the storage tank, ensuring the stability of the spraying device.

[0016] Preferably, the bottom of the crossbar is provided with a side-opening mounting box, and the circular chainsaw is rotated inside the mounting box and is electrically driven by a motor.

[0017] Preferably, the carbon fiber mesh protective cover is formed by splicing two half-body mesh covers together. The half-body mesh cover has a slot A that fits on the outer side of the mounting bracket, and the half-body mesh cover has a slot B that communicates with slot A and is inserted into the support leg, as well as a plug that is fixed on the half-body mesh cover and is inserted into the slot on the top of the support leg.

[0018] Preferably, after the two half-body mesh covers are inserted into the support feet from both sides of the mounting bracket, the two half-body mesh covers are joined together and then secured by two locking buckles arranged symmetrically at the front and back.

[0019] The slotted and insert design of the half-body mesh cover makes installation and maintenance more convenient, ensuring the stability and safety of the protective cover. The interlocking and locking design of the two half-body mesh covers makes the assembly of the protective cover quick and secure, improving the overall safety of the drone during operation.

[0020] Compared with the prior art, the technical effects and advantages of this utility model are:

[0021] This chainsaw-equipped agricultural drone achieves efficient plant protection operations through its modular design. The drone itself features a rotor design, allowing for vertical takeoff, landing, and hovering by adjusting the rotor speed and direction via remote control or an autonomous control system. The pesticide spraying device, located beneath the drone, includes a storage tank, a pesticide pump, and nozzles, which evenly spray pesticides in a mist during operation. Simultaneously, a circular chainsaw mounted on the bottom of the drone prunes branches using equally spaced chainsaws. A carbon fiber mesh protective cover surrounds the chainsaw and spraying device to prevent debris generated during operation from injuring the drone or the operator.

[0022] The application of chainsaw-equipped agricultural drones has significantly improved the efficiency of plant protection operations. The drones' rapid deployment and precise spraying capabilities allow them to quickly reach designated areas and efficiently complete spraying tasks. The chainsaw attachment enables efficient pruning of branches, replacing manual high-altitude work and greatly reducing labor intensity and safety risks. Furthermore, the drones' autonomous control systems enable precise spraying, reducing pesticide usage, thereby lowering costs and minimizing environmental impact.

[0023] The modular design of the drone simplifies maintenance and repair. For example, the crossbar and mounting block design makes changing pesticides or cleaning nozzles quick and easy, while the mounting box and carbon fiber protective cover facilitate the maintenance and replacement of the chainsaw. Furthermore, the symmetrical locking design of the protective cover not only enhances structural safety but also ensures that the cover will not shift due to vibration during operation, effectively protecting the drone and the operator. These designs allow the chainsaw-equipped agricultural drone to improve both operational efficiency and safety. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] The following combination Figures 1 to 5 This application will be described in further detail.

[0032] This application discloses a chainsaw-equipped agricultural drone, including a drone body 1, a pesticide spraying device 2, a circular chainsaw 3, and a carbon fiber mesh protective cover 4.

[0033] The drone body 1 has vertical take-off and landing and hovering functions and is operated by a remote controller or an autonomous control system;

[0034] The pesticide spraying device 2 is located below the drone body 1 and is used for spraying pesticides; the bottom of the mounting platform 5 is provided with a mounting bracket 7, and the pesticide spraying device 2 is mounted on the mounting bracket 7. The pesticide spraying device 2 includes a storage tank 21 and a nozzle 22 inserted and installed on the mounting bracket 7. The storage tank 21 is connected to the nozzle 22 through a liquid pipeline and a liquid pump.

[0035] A crossbar 8 is provided between the two support legs 6. An integrally formed mounting block 9 is fixed to the top of the crossbar 8. The mounting block 9 has a slot 10, into which a support limiting block 11, which supports the bottom of the medicine storage tank 21 and limits its outer surface, is engaged and fixed. The crossbar 8 provides additional structural support, enhancing the overall stability of the drone during operation. The slot 10 and support limiting block 11 on the mounting block 9 ensure the safe fixation of the medicine storage tank 21 during drone operation, preventing it from moving or tipping over due to vibration or other external forces. The design of the crossbar 8 and mounting block 9 makes maintenance and repair of the spraying device more convenient; for example, changing the pesticide solution or cleaning the nozzle 22 can be done quickly.

[0036] Several circular chainsaws 3 are arranged at equal intervals and used for pruning branches; the bottom of the drone body 1 is equipped with a mounting platform 5, and two support feet 6 are fixedly connected to each side of the mounting platform 5. The fixed connection between the mounting platform 5 and the support feet 6 provides the drone with additional stability, especially when spraying pesticides and pruning branches, this stability is crucial for maintaining operational accuracy. The support feet 6 can provide protection when the drone lands, preventing the drone body 1 from directly contacting the ground and reducing collision damage.

[0037] The bottom of the crossbar 8 is equipped with a side-opening mounting box 12. The circular chainsaw 3 is rotatably mounted inside the mounting box 12 and is electrically driven by a motor. The mounting box 12 provides a certain degree of protection for the circular chainsaw 3, preventing damage to the chainsaw due to collisions or falls during operation. The side-opening design makes the installation, maintenance, and replacement of the chainsaw more convenient and quick, allowing operators to easily access the chainsaw for necessary operations. The chainsaw is mounted inside the mounting box 12, which does not adversely affect the aerodynamic performance of the drone and prevents the chainsaw from being directly exposed to the external environment. The mounting box 12 prevents operators' body parts from coming into contact with the chainsaw, reducing the risk of accidents.

[0038] The carbon fiber mesh protective cover 4 is located below the drone and covers the outside of the circular chainsaw 3 and the pesticide spraying device 2, separating the drone body 1 from the circular chainsaw 3 and the pesticide spraying device 2 to prevent cutting debris from flying and damaging the propeller on the drone body 1.

[0039] The carbon fiber mesh protective cover 4 is composed of two half-body mesh covers 41 joined together. Each half-body mesh cover 41 has a slot A42 that fits over the outer side of the mounting bracket 7. It also has a slot B43 that communicates with slot A42 and engages with the support leg 6, as well as an insert block 44 fixed to the half-body mesh cover 41 and engaged with the slot 61 at the top of the support leg 6. This two-part mesh cover design simplifies the installation and removal of the protective cover, facilitating maintenance and cleaning.

[0040] After the two half-body mesh covers 41 are inserted into the support feet 6 from both sides of the mounting bracket 7, the two half-body mesh covers 41 are joined together and then fastened by two locking buckles 45 arranged symmetrically at the front and back.

[0041] The locking buckles 45 securely fasten the two half-body net covers 41, ensuring a stable connection during drone operation and preventing displacement due to vibration or other reasons. The symmetrical arrangement of the locking buckles 45 provides additional security, ensuring the protective covers will not easily detach under external forces, thus protecting the drone and operators. The symmetrical design of the locking buckles 45 not only increases structural safety but also makes the overall design more aesthetically pleasing and harmonious. The locking buckle design allows for quick installation and removal of the protective covers, improving drone preparation and operational efficiency.

[0042] The drone body 1 employs a rotor design, adjusting the rotor speed and direction via signals sent by a remote controller or autonomous control system to achieve vertical takeoff and landing and hovering. The drone body 1 typically contains a battery as its power source, as well as necessary sensors and a flight control system to maintain stability.

[0043] The pesticide spraying device 2 is located below the drone body 1 and typically consists of a storage tank 21, a pesticide pump, and a nozzle 22. During operation, the pesticide solution is pumped from the storage tank 21 to the nozzle 22 and sprayed out through the tiny holes of the nozzle 22 to form a mist, so as to evenly cover the crops or trees.

[0044] The circular chainsaw 3 is mounted below the drone and typically consists of several chainsaws arranged at equal intervals. These chainsaws are driven by motors and can trim branches, clear obstacles, or shape trees while the drone is in flight.

[0045] A carbon fiber mesh protective cover 4 is located below the drone, covering the circular chainsaw 3 and the pesticide spraying device 2. The protective cover is typically made of high-strength, lightweight carbon fiber material, which effectively prevents debris from flying during tree trimming and protects the drone body 1, especially the propeller, from damage.

[0046] The carbon fiber mesh protective cover 4 prevents debris from cutting from injuring the drone body 1 and operators, improving operational safety. The drone can quickly reach designated areas and perform efficient spraying and pruning operations, significantly improving work efficiency compared to traditional manual methods. Chainsaw agricultural drones can replace manual labor for high-altitude operations, reducing the risks and labor intensity for personnel working at heights. The drone's autonomous control system enables precise spraying, reducing pesticide use, lowering costs, and minimizing environmental impact. The drone's modular design makes maintenance and replacement of components simpler and faster. The drone's remote control or autonomous control system allows operators to flexibly control the drone for various complex flight and operational tasks.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
