Description

Technical Field

[0001] This utility model relates to the field of spraying drone technology, and in particular to an agricultural spraying drone. Background Technology

[0002] Agricultural spraying drones typically consist of a flight platform, a spraying system, a GPS navigation system, and a remote controller. The flight platform is the main body of the drone, carrying the power system and sensor equipment; the spraying system is responsible for storing pesticide solution and spraying it onto the target crop; the GPS navigation system is used to enable the drone's autonomous navigation and positioning; and the remote controller is used to control the drone's flight path and spraying operations. These components work together to enable pesticide spraying drones to complete pesticide spraying operations efficiently and accurately.

[0003] Currently, the spray nozzles of agricultural spraying drones are generally installed below the rotors, and due to structural limitations, the nozzles are relatively short, unable to penetrate beneath the branches and leaves of crops. In actual operation, drones typically maintain a spraying height of about one meter above the crops. However, for densely growing crops, the interlacing branches and leaves form a dense surface cover. Because the nozzles cannot penetrate deep into the crop, most of the sprayed pesticide adheres only to the surface leaves. Furthermore, the pesticide on the leaves is easily evaporated by direct sunlight, resulting in a significant decrease in the utilization rate of the pesticide's active ingredients, directly affecting the spraying effect.

[0004] Therefore, further improvements are needed, and to this end, we have proposed an agricultural spraying drone. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an agricultural spraying drone.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an agricultural spraying drone, including a plant protection drone body and four hoses installed on the plant protection drone body. Each of the four arms of the plant protection drone body is fixedly connected to an integrated shell, and each of the four integrated shells is equipped with an electric lateral movement component.

[0007] Each of the four electric transverse components is connected to a rotating component between itself and the integrated housing. The movable ends of the four rotating components are fixedly connected to long tubes, and one end of the long tubes is fixedly connected to the liquid outlet of the adjacent hose.

[0008] The other end of each of the four long tubes is connected to a movable tube. Each of the four long tubes has a locking bolt that extends into the interior on one side of its outer surface. The locking bolt matches the movable tube. The liquid outlet ends of each of the four movable tubes are fixedly connected to pesticide nozzles.

[0009] Furthermore, each of the four electric traverse components includes a motor, which is fixedly mounted on the inner wall of one side of the integrated housing. The drive end of the motor is fixedly connected to a screw, and the screw is rotatably connected to the integrated housing. The outer surface of the screw is threaded with a slide block, which can drive the rotating component to run.

[0010] Furthermore, each of the four rotating components includes two racks, which are fixedly connected to the slide. A gear is meshed with the top of the rack, and a rotating shaft is fixedly connected to the inner surface of the gear. The rotating shaft passes through the integrated housing and is rotatably connected to the integrated housing. Both rotating shafts are fixedly connected to the long tube. The two racks synchronously drive the two gears to rotate, so that the two rotating shafts rotate synchronously, thereby driving the long tube to rotate and avoiding jamming.

[0011] Furthermore, both racks are slidably connected to the slide block by guide rails, and the guide rails are fixedly installed at the bottom of the integrated housing. The guide rails limit the movement of the slide block and racks, ensuring the stability of their movement.

[0012] Furthermore, piston rings are fixedly fitted onto the outer surfaces of all four movable tubes, and the piston rings are sealed and fitted to the inner wall of the long tube. The sealing design of the piston rings effectively prevents leakage of the liquid medicine and improves the sealing performance of the system.

[0013] Furthermore, the outer surfaces of the four movable tubes are provided with multiple screw holes, which are matched with locking bolts. The design of multiple screw holes and multi-level adjustment improves the overall applicability.

[0014] The beneficial effects of this utility model are:

[0015] 1. When in use, this utility model uses a telescopic and adjustable movable tube and a long tube to connect and fix the tube with locking bolts, which allows the pesticide nozzle to penetrate deep into the branches and leaves of crops for spraying. This effectively solves the technical problem that traditional spraying drones can only adhere to the surface leaves of crops due to the fixed nozzle and insufficient length. It significantly improves the coverage and effective utilization rate of pesticides inside crops.

[0016] 2. In use, this utility model adopts a structural design that uses an electric horizontal movement component to drive a rotating component to rotate and adjust the long tube, which realizes the retraction and lowering of the pesticide nozzle and avoids affecting the use of the plant protection drone.

[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-4 As shown, an agricultural spraying drone is disclosed, comprising a plant protection drone body 1 and four hoses 5 mounted on the plant protection drone body 1. Each of the four arms of the plant protection drone body 1 is fixedly connected to an integrated housing 4. Each of the four integrated housings 4 houses an electric traverse assembly, each of which includes a motor 12. The motor 12 is fixedly mounted on one inner wall of the integrated housing 4. The integrated housing 4 is made of aluminum alloy, which has good thermal conductivity, facilitating heat dissipation from the motor 12. A screw 13 is fixedly connected to the drive end of the motor 12, and the screw 13 is rotatably connected to the integrated housing 4. A slide 11 is threaded onto the outer surface of the screw 13. The motor 12 is electrically connected to a built-in controller in the plant protection drone body 1, facilitating control of the motor 12's operation. The screw 13 has a threaded helix angle smaller than the friction angle, giving it a self-locking capability to prevent displacement due to vibration or load.

[0026] Each of the four electric lateral movement components is connected to a rotating component between itself and the integrated housing 4. The movable ends of the four rotating components are fixedly connected to long tubes 2, and one end of the long tubes 2 is fixedly connected to the liquid outlet end of the adjacent hose 5. Each of the four rotating components includes two racks 14, and the racks 14 are fixedly connected to the slide 11. The top of the racks 14 is meshed with a gear 16, and the inner surface of the gear 16 is fixedly connected to a rotating shaft 10. The rotating shaft 10 passes through the integrated housing 4 and is rotatably connected to the integrated housing 4. Both rotating shafts 10 are fixedly connected to the long tubes 2. Both racks 14 and the slide 11 are slidably connected to a guide rail 15, and the guide rail 15 is fixedly installed at the bottom of the integrated housing 4. The rotating shaft 10 is rotatably connected to the integrated housing 4 through a bearing seat. The bearing seat body is fixed to the integrated housing 4, and the inner ring of the bearing inside the bearing seat is fixed to the rotating shaft 10.

[0027] Each of the four long tubes 2 has a movable tube 3 inserted at its other end. Each of the four long tubes 2 has a locking bolt 8 extending through to the interior on one side of its outer surface, and the locking bolt 8 matches the movable tube 3. Each of the four movable tubes 3 has a pesticide nozzle 6 fixedly connected to its liquid outlet end. Each of the four movable tubes 3 has a piston ring 9 fixedly fitted on its outer surface, and the piston ring 9 is sealed and fitted to the inner wall of the long tube 2. Each of the four movable tubes 3 has multiple screw holes 7 on its outer surface, and the screw holes 7 match the locking bolt 8. Each of the piston rings 9 has two sealing rings fixedly fitted on its outer surface, and the sealing rings are sealed and fitted to the inner wall of the long tube 2 to ensure airtightness.

[0028] Working principle: During operation, the agricultural drone body 1 provides flight support, and the pesticide solution is delivered to each long tube 2 through four hoses 5. Before operation, the insertion length of the movable tube 3 in the long tube 2 can be adjusted to adapt to different operating heights. After adjustment, tighten the locking bolt 8 so that the locking bolt 8 matches and locks with the screw hole 7 on the outer surface of the movable tube 3, thereby fixing the movable tube 3 to the long tube 2. At the same time, the piston ring 9 on the outer surface of the movable tube 3 seals against the inner wall of the long tube 2 to prevent pesticide leakage.

[0029] During spraying, the electric lateral movement assembly is activated, and the motor 12 drives the screw 13 to rotate within the integrated housing 4, causing the slide 11, which is threaded onto the outer surface of the screw 13, to slide along the guide rail 15. The movement of the slide 11 drives the fixedly connected rack 14 to move synchronously. The rack 14 meshes with the gear 16, causing the gear 16 to drive the rotating shaft 10 to rotate on the integrated housing 4. In turn, the rotating shaft 10 drives the long tube 2 to rotate and adjust its angle, so that the pesticide nozzle 6 at the end of the movable tube 3 is adjusted to a suitable spraying position. This design allows the nozzle to penetrate deep into the crop canopy, achieving three-dimensional spraying.

[0030] When spraying is not required or storage is needed, the electric lateral movement component operates in reverse. The slide 11 drives the rack 14 to move in the opposite direction. Through the transmission of the gear 16 and the rotating shaft 10, the long tube 2 is rotated and retracted, so as to prevent the movable tube 3 and the pesticide nozzle 6 from affecting the normal take-off, landing and transportation of the drone.

[0031] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification.
