DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0039] See also Figures 1 to 12 A drone device for preventing and controlling agricultural pests and diseases comprises a protective shell 1, a medicine box component 2 is detachably installed at the bottom of the protective shell 1, wing components 3 are installed at the four corners of the outer circle of the protective shell 1, mounting plates 4 for fixing the medicine box component 2 are installed on both sides of the interior of the protective shell 1, and fixing components 5 are installed on both sides of the interior of the protective shell 1 adjacent to the mounting plate 4. The medicine box component 2 comprises a first box body 21 and a second box body 22, the first box body 21 and the second box body 22 are integrally formed, and clamping plates 23 are fixedly installed on both sides of the second box body 22 corresponding to the mounting plate 4, and clamping components 6 are installed on both sides of the second box body 22 adjacent to the clamping plate 23, and a battery 7 is installed on the clamping component 6. The fixing component 5 installs and removes the battery 7 according to the state of the medicine box component 2.

[0040] During actual use, the UAV can be driven to perform flight operations by controlling the wing component 3. The protective shell 1 is used to protect the internal components. The interior of the medicine box component 2 is filled with medicines for preventing and controlling pests and diseases. The battery 7 is used to power the UAV. When the medicine box component 2 is not installed on the UAV, the battery 7 is clamped by the clamping component 6. When the medicine box component 2 is installed on the UAV, the battery 7 is connected to the fixing component 5, and the battery 7 can play a power supply role. When in use, a medicine box component 2 full of medicine can be installed into the interior of the protective shell 1 first. At this time, the battery 7 is automatically connected to the fixing component 5, and the UAV can work normally. At this time, the UAV is controlled to perform spraying operations. During the spraying operation, workers can use new medicine box components 2 to fill medicines and place them in designated locations. When the medicines in the medicine box component 2 on the UAV are sprayed exhausted, the UAV will fly to the designated location through a pre-set program and then land. When landing, the medicine box component 2 will first touch the ground. At this time, the medicine box part Part 2 acts as a landing gear. When the landing is completed, because the wing part 3 stops working, the drone will release the medicine box part 2 under the action of its own weight, but the battery 7 will not be removed with the release of the medicine box part 2. At this time, the battery 7 is still connected to the fixing part 5, and the drone still has the ability to work. At this time, the drone takes off again. Because the medicine box part 2 is released, when the drone takes off again, the medicine box part 2 will stay in place due to its own weight. At this time, because the medicine box part 2 is moved out of the protective shell 1, the battery 7 and the fixing part 5 are in a semi-connected state. The drone flies to the new medicine box part 2 and then falls. At this time, the mounting plate 4 will automatically clamp the new medicine box part 2. When the medicine box part 2 carries the new battery 7 into the protective shell 1, the new battery 7 will push the battery 7 on the original drone out of the device and connect the new battery 7 to the fixing part 5 under the action of the drone's own weight. At this time, the drone can work again.

[0041] A central groove 41 is provided in the middle position of the interior of the mounting plate 4, and the clamping plate 23 is slidably clamped in the interior of the central groove 41. Mutually symmetrical clamping grooves 42 are provided in the interior of the mounting plate 4 at positions on both sides of the central groove 41. Two mutually symmetrical fixed clamping grooves 231 are also provided at positions corresponding to the clamping plate 23 and the clamping groove 42. A trapezoidal slider 43 is provided for sliding inside the clamping groove 42. A first spring 45 is fixedly connected between the trapezoidal slider 43 and the clamping groove 42. Z-shaped rods 44 are fixedly installed on both sides of the trapezoidal slider 43. Matching grooves are provided on the two side walls corresponding to the clamping groove 42 and the Z-shaped rod 44. The matching groove is formed by the first channel 421, the second channel 422, the limiting groove 423, and the third channel 424 being connected and combined in sequence. The third channel 424 has a step inside. The step located inside the third channel 424 is a vertical surface, and the step located at the position of the limiting groove 423 is an inclined surface. One end of the Z-shaped rod 44 is located inside the matching groove.

[0042] When the medicine box component 2 is in the installed state, the trapezoidal slider 43 is pushed by the first spring 45 into the interior of the fixed card slot 231, and then the clamping plate 23 is clamped by the trapezoidal slider 43, that is, the first box body 21 and the second box body 22 are fixed inside the protective shell 1. At this time, if the drone lands, under the weight of the drone itself, the mounting plate 4 will drop, and then the trapezoidal slider 43 will be pushed by the lower section of the clamping plate 23 into the interior of the clamping slot 42. At this time, the Z-shaped rod 44 is pushed to move. When the Z-shaped rod 44 is pushed, it will move along the first channel 421. Because of the steps inside the U-shaped kit 242, the Z-shaped rod 44 cannot enter the interior of the U-shaped kit 242 at this time, but will pass through the first channel When the clamping plate 23 slides out of the center groove 41, the trapezoidal slider 43 and the Z-shaped rod 44 are driven to rebound under the action of the first spring 45. At this time, the end of the Z-shaped rod 44 will be supported by the limit groove 423, and the trapezoidal slider 43 cannot move out of the clamping slide groove 42. When the next clamping plate 23 enters the center groove 41, the clamping plate 23 completely enters the center groove 41 due to the landing of the drone. The lower section of the clamping plate 23 will push the trapezoidal slider 43 again. At this time, one end of the Z-shaped rod 44 is driven to enter the third channel 424. Because the interior of the third channel 424 has a step, refer to Figure 5 As shown, a boss is formed between the third channel 424 and the second channel 422, and the top of the boss is located in the lower middle position of the limit groove 423, so the Z-shaped rod 44 will undergo elastic deformation. As the drone takes off again, when the fixed slot 231 coincides with the card slot 42, the trapezoidal slider 43 is driven by the first spring 45 to re-enter the interior of the fixed slot 231, thereby being able to fix the medicine box component 2 again.

[0043] By setting the mounting plate 4 and the clamping plate 23, the device allows the drone to replace the new medicine box component 2 only by landing and taking off when the internal medicine is exhausted, thereby reducing waiting time and improving continuous working ability. In addition, multiple medicine box components 2 can be set at one time, which can realize automatic medicine change. There is no need for workers to approach the drone to change medicine, which can prevent the medicine from causing harm to the workers. Secondly, it can reduce the time for medicine change, making it have a higher degree of automation.

[0044] The clamping component 6 includes two symmetrical fixed blocks 61, a first U-shaped slider 62 is slidably clamped between the two fixed blocks 61, and the first U-shaped slider 62 has a limit slider 63 integrally formed on both sides of the interior, and both sides of the battery 7 are provided with a limit slide groove 72 corresponding to the limit slider 63. The fixed block 61 is fixedly installed on the side wall of the second box body 22, and a plurality of evenly distributed third springs 64 are fixedly connected between the first U-shaped slider 62 and the side wall of the second box body 22. The fixing component 5 includes a support block 51, which is fixedly installed on the inner wall of the protective shell 1, and a rotating The movable plate 52 has a power interface 53 on one end of the rotating plate 52 away from the support block 51 and close to the battery 7, and an output interface 71 is provided on the lower surface of one end of the battery 7 close to the power interface 53. A second spring 54 is fixedly connected between the side of the support block 51 away from the battery 7 and the inner wall of the protective shell 1. The upper wall of the protective shell 1 is provided with two battery outlets 11 corresponding to the battery 7, and a triangular block 12 is provided between the two battery outlets 11. The triangular block 12 is fixedly installed on the upper surface of the protective shell 1, and anti-slip baffles 13 are fixedly installed on both sides of the triangular block 12 on the upper surface of the protective shell 1.

[0045] When the battery 7 and the medicine box component 2 are both installed inside the protective shell 1, the output interface 71 is slidably connected to the power interface 53, and the first U-shaped slider 62 and the battery 7 are pushed under the action of the third spring 64. At this time, the battery 7 pushes the rotating plate 52, so that the rotating plate 52 is in a vertical state. When the medicine box component 2 is disassembled from the protective shell 1, the limiting slide groove 72 will slide out from the top of the limiting slider 63, and the second box body 22 will slide out of the protective shell 1 with the fixed block 61, the first U-shaped slider 62, and the third spring 64. At this time, because the output interface 71 is slidably connected to the power interface 53, the battery 7 is still clamped in the inside of the protective shell 1 by the fixed component 5, but under the action of the second spring 54 , the rotating plate 52 will rotate around the support block 51 and tilt, and tilt to a position that coincides with the battery outlet 11. At this time, when the new medicine box component 2 carries the new battery 7 into the protective shell 1, the new battery 7 will first contact the inclined surface below the support block 51. At this time, the battery 7 drives the first U-shaped slider 62 to compress the third spring 64. As the drone gradually lands, the battery 7 will push the support block 51 to gradually become vertical. At this time, the second spring 54 is compressed. When the drone is completely landed, the battery 7 moves to the top of the power interface 53. Under the action of the second spring 54, the support block 51 is pushed to fit with one side surface of the battery 7. At this time, the power interface 53 is connected to the output interface 71, and the drone is powered on again.

[0046] By providing a fixing component 5 and a clamping component 6, the device can automatically remove the old battery and replace it with a new fully charged battery when the medicine box component 2 is replaced as the drone lands, so that the drone can have a higher endurance and does not need workers to replace it, further improving the degree of automation.

[0047] An anti-collision component 8 for protecting the wing component 3 is fixedly installed on the outer surface of the protective shell 1, and the anti-collision component 8 includes two mutually symmetrical first anti-collision rings 81 and two mutually symmetrical second anti-collision rings 82, a first hollow rod 83 is fixedly installed on one end of the first anti-collision ring 81 close to the second anti-collision ring 82, and a second hollow rod 84 is fixedly installed on one end of the second anti-collision ring 82 close to the first anti-collision ring 81, the first hollow rod 83 and the second hollow rod 84 are rotatably installed between them, and a center rod 86 is rotatably installed at the connection between the first hollow rod 83 and the second hollow rod 84, and the center rod 86 is fixedly installed on the outer surface of the protective shell 1, an elastic rope 85 is fixedly connected between the inside of the first hollow rod 83 and the inside of the second hollow rod 84, and a slide rail 87 is fixedly installed between the two first anti-collision rings 81 and the two second anti-collision rings 82.

[0048] When the drone is completely landed, the new battery 7 will completely push the used battery 7 out through the battery outlet 11. Because the fixing part 5 is inclined, and the battery outlet 11 is consistent with the inclination of the fixing part 5, the old battery 7 will also be inclined when it is pushed out. When the old battery 7 is completely pushed out of the battery outlet 11, the old battery 7 will fall onto the triangular block 12 due to the inclination. Under the action of gravity, the battery 7 will gradually slide along the slope to the slide rail 87. When the drone is working normally At this time, the two second hollow rods 84 are pulled horizontally by the action of the elastic rope 85. At this time, the first anti-collision ring 81 and the second anti-collision ring 82 protect the four wing components 3 to achieve anti-collision effect. When the battery 7 slides onto the slide rail 87, the force on the first anti-collision ring 81 and the second anti-collision ring 82 increases, causing the elastic rope 85 to be stretched, and the first anti-collision ring 81 and the second anti-collision ring 82 rotate around the central rod 86 until the first anti-collision ring 81 and the second anti-collision ring 82 touch the ground. At this time, the battery 7 on the slide rail 87 will also be firmly placed on the ground.

[0049] The device is provided with an anti-collision component 8. When the drone is working normally, the anti-collision component 8 can protect the wing component 3 to prevent damage to the drone caused by collision. When the drone is replacing the battery 7, the anti-collision component 8 can play the role of unloading and buffering, and can place the battery stably on the ground, making it easy for workers to take it away for charging operations.

[0050] The wing component 3 includes a connecting rod 31, and a wing blade 32 is rotatably installed on the upper surface of one end of the connecting rod 31 away from the protective shell 1, and a medicine nozzle 33 is fixedly installed on the lower surface of the end of the connecting rod 31 away from the protective shell 1. A first pipe 34 for connecting the medicine nozzle 33 is fixedly installed on the lower surface of the connecting rod 31, and a hose 341 is fixedly connected to the end of the first pipe 34 away from the medicine nozzle 33, and a connecting component 35 is fixedly connected to the end of the hose 341 away from the medicine nozzle 33. The connecting component 35 is fixedly installed on the inner surface of the protective shell 1.

[0051] When in use, the wing blades 32 rotate to generate lift and drive the drone to fly. During flight, the wing blades 32 will continuously drive the airflow to flow downward, and the medicine nozzle 33 can absorb the medicine liquid and spray it. The wind blown out by the wing blades 32 can better blow the medicine liquid sprayed by the medicine nozzle 33 to the roots and stems and leaves of crops, thereby improving the spraying effect of the medicine.

[0052] The connecting component 35 includes two symmetrical side baffles 351, a magnet joint 353 is slidably mounted between the two side baffles 351, a second U-shaped slider 352 is slidably mounted on one side of the side baffle 351, a plurality of metal tubes 24 corresponding to the connecting component 35 are fixedly mounted on the upper surface of the second box body 22, a metal joint 241 is fixedly mounted on one end of the metal tube 24 close to the connecting component 35, and U-shaped kits 242 corresponding to the side baffle 351 are fixedly mounted on both sides of the metal tube 24, a second pipe 354 is fixedly mounted on the side of the magnet joint 353 away from the metal joint 241, the second pipe 354 passes through the second U-shaped slider 352 and is fixedly connected to the hose 341, and the magnet joint 353 is fixedly mounted on the second A fourth spring 355 is fixedly connected between the U-shaped sliders 352, an incomplete gear 356 is rotatably installed inside one of the side baffles 351, one end of the incomplete gear 356 is connected to a dividing blade 357 through an axle rod, a first rack 243 and a second rack 244 are installed on the inner side wall of a U-shaped kit 242 corresponding to the incomplete gear 356, the first rack 243 and the second rack 244 are located at different heights, a first slot body 358 and a second slot body 359 that are interconnected are provided on the sides of the two side baffles 351 that are close to each other, the second slot body 359 is inclined, and sliding rods used in conjunction with the first slot body 358 are fixedly installed on both sides corresponding to the magnet joint 353 and the side baffles 351.

[0053] When the medicine box component 2 is not installed, the magnet joint 353 is located at the position of the first slot 358. When the medicine box component 2 is installed into the protective shell 1, the U-shaped kit 242 is also slidably installed with the side baffle 351, and as the protective shell 1 drives the side baffle 351 to descend, the metal joint 241 gradually moves to a position horizontal with the magnet joint 353. At this time, the magnet joint 353 is attracted by the metal joint 241 and fits with the metal joint 241. When the drone takes off, the medicine box component 2 will drop a distance, so the metal joint 241 will drive the magnet joint 353 to slide down along the second slot 359. Because the second slot 359 is inclined, the magnet joint 353 and the metal joint 241 are gradually locked, so that a sealing effect is achieved between the magnet joint 353 and the metal joint 241. By setting the connecting component 35, the device does not need to be loaded on the medicine box component 2, and can cooperate with the wing blade 32 to increase the spraying effect, and can automatically lock according to the disassembly and installation of the medicine box component 2, thereby improving the use effect of the device.

[0054] As the metal joint 241 rises, the first rack 243 and the second rack 244 will act on the incomplete gear 356 in turn, so that the incomplete gear 356 can only rotate in one direction at all times. When the medicine box component 2 is disassembled, the metal tube 24 will drive the metal joint 241 to rise a certain distance first. At this time, the metal joint 241 drives the magnet joint 353 back to the position of the first slot 358. At this time, the first rack 243 will first contact the incomplete gear 356, driving the incomplete gear 356 to rotate. At this time, the incomplete gear 356 will drive the splitting blade 357 to rotate. When the splitting blade 357 rotates, it will cut the connection between the metal joint 241 and the magnet joint 353, so that the metal joint 241 and the magnet joint 353 are separated. , and the sliding rod on the magnet joint 353 enters the interior of the first groove body 358. At this time, the metal tube 24 is driven down by the medicine box component 2, which will separate the metal joint 241 from the magnet joint 353. Under the action of the fourth spring 355, the magnet joint 353 is pulled again to the end of the first groove body 358. At the same time, the second rack 244 acts on the incomplete gear 356 to make it rotate. The incomplete gear 356 drives the splitting blade 357 to rotate to the outside of the side baffle 351, which is convenient for the next replacement operation. By setting the splitting blade 357, the device uses magnetic attraction to connect the metal joint 241 with the magnet joint 353, and with the disassembly and installation of the medicine box component 2, the pipeline can be automatically connected and separated to prevent the pipeline from being entangled, thereby improving the autonomous working ability of the device.
