[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0036] Embodiment 1, as Figure 1 As shown, an agricultural aerial pesticide application device that can quickly replenish medicine water includes a medicine liquid storage tank 5, a medicine replenishing structure 1 is fixedly connected to the upper end of the medicine liquid storage tank 5, a medicine spraying drone 2 is arranged on the upper end of the medicine replenishing structure 1, a plurality of spray structures 3 are arranged on the lower side of the medicine spraying drone 2, a medicine liquid storage structure 4 is fixedly connected to the lower end of the medicine spraying drone 2, and the plurality of spray structures 3 are connected to the inner cavity of the medicine liquid storage structure 4.

[0037] Although pesticides can kill pests quickly, they will inevitably produce pesticide residues in agricultural products during use, and will pollute the soil, affecting the subsequent crop planting. Therefore, at this stage, the spraying of pheromone insect repellents is gradually being promoted. The pests are driven away by the disgusting ingredients in the pheromone, so that the pests will actively leave the crops sprayed with insect repellents.

[0038] However, in the process of large-scale spraying, relying solely on manual spraying is very inefficient, time-consuming and labor-intensive, so spraying is generally carried out using drones.

[0039] Further, in order to realize the carrying of non-toxic insect repellents to replace pesticides over farmland for spraying and pest control, see Figure 2 The spraying drone 2 includes a fuselage 21, a plurality of rotors 23 are rotatably connected to the outer surface of the fuselage 21 in an annular distribution, the middle of the outer surface of the plurality of rotors 23 is fixedly connected to the adjacent spray structure 3, an oil tank 22 is fixedly connected to the inner surface of the fuselage 21, connecting beams 24 are symmetrically fixedly connected to the inner surface of the fuselage 21, and the ends of the two connecting beams 24 close to each other are fixedly connected to the liquid medicine storage structure 4, and a support frame 25 is symmetrically fixedly connected to the lower end of the fuselage 21.

[0040] It should be noted that the above-mentioned spraying drone 2 is a conventional drone structure, which has been widely used in the prior art. In the present invention, it is only used to realize the function of carrying pesticides and spraying through the spray structure 3, and its internal structure, operating principle, wiring, and control method are not described in detail.

[0041] Further, in order to realize the spraying of pollution-free insect repellent, see Figure 3 The spray structure 3 includes a connecting rod 31 fixedly connected to the outer surface of the rotor 23, the lower end of the connecting rod 31 is symmetrically fixedly connected to the spray head 32, the upper ends of the two spray heads 32 are fixedly connected to the connecting pipe three 33, the ends of the two connecting pipes three 33 away from the spray head 32 are fixedly connected to the tee 34, and the upper end of the tee 34 is fixedly connected to the connecting pipe four 35 connected to the output end of the supply pump 42.

[0042] The insect repellent is provided to the connecting pipe four 35 through the liquid medicine storage structure 4, and then distributed to the connecting pipe three 33 through the connecting pipe three 33, and sent to the spray head 32 for spraying via the connecting pipe three 33. The spraying range is larger than the manual spraying range, and the UAV has a fast flying speed and high spraying efficiency, which can save a lot of time and energy.

[0043] During the operation of this embodiment, the liquid medicine storage tank 5 is used as a base station to store insect repellent, and the liquid medicine storage structure 4 is supplemented with insect repellent through the cooperation of the medicine replenishing structure 1 and the spraying drone 2. The liquid medicine storage structure 4 and the spray structure 3 are driven above the farmland by the action of the spraying drone 2, and the insect repellent is sprayed through the spray head 32 by the cooperation of the liquid medicine storage structure 4 and the spray structure 3, and the insect repellent is sprayed onto the crops in the farmland. During the spraying process, the wind pressure of the spraying drone 2 is used to continuously stir the insect repellent inside the liquid medicine storage structure 4 to avoid precipitation of the insect repellent inside the liquid medicine storage structure 4, thereby further improving the spraying efficiency.

[0044] Embodiment 2. Based on embodiment 1, this embodiment guides the drone to fall through the cooperation of the trapezoidal guide block 13 and the support frame 25, and stably lands on the liquid medicine storage tank 5. The cooperation of the connecting component 15 and the snap-fit ​​component 14 drives the snap-fit ​​component 14 to expand outward, limits the support frame 25, and promotes the connecting component 15 to dock with the liquid medicine storage structure 4, so as to replenish the insect repellent in the liquid medicine storage structure 4. Furthermore, it is also possible to strengthen the connection between the liquid medicine storage structure 4 and the connecting component 15 and avoid leakage of the insect repellent, thereby avoiding shaking of the drone due to wind and collision during the replenishment process.

[0045] Specifically, in order to achieve rapid replenishment of spray drones and provide a platform for them to stay, refer to Figure 4 The medicine replenishing structure 1 includes a supporting block 12 fixedly connected to the upper end of the medicine liquid storage box 5, and the inner surface of the supporting block 12 is symmetrically provided with slide grooves 11, and the inner surfaces of the two slide grooves 11 are symmetrically slidably connected with snap-fit ​​components 14. Four trapezoidal guide blocks 13 are rectangularly distributed and fixedly connected to the upper end of the medicine liquid storage box 5, and a connecting component 15 is commonly provided on the bottom wall of the inner cavity of the medicine liquid storage box 5 and the upper end of the supporting block 12.

[0046] The upper end of the medicine liquid storage box 5 serves as a landing platform for the support frame 25, and the supporting block 12 is used to support the medicine liquid storage structure 4. The trapezoidal guide blocks 13 around it can guide the support frame 25 to fall toward the middle to avoid landing deviation. Furthermore, the connecting component 15 connected to the inner cavity of the medicine liquid storage box 5 can cooperate with the snap-fit ​​component 14 to limit the support frame 25, and simultaneously use the connecting component 15 to replenish the insect repellent to the medicine liquid storage structure 4.

[0047] Further, to achieve the transport of insect repellent into the drone, see Figure 5 The connecting assembly 15 includes a water pump 151 fixedly connected to the bottom wall of the inner cavity of the medicine liquid storage tank 5, a pressure chamber 153 is opened in the inner cavity of the supporting block 12, a connecting pipe 152 connected to the inner cavity of the pressure chamber 153 is fixedly connected to the upper end of the water pump 151, a connecting pipe 2 154 connected to the upper end of the supporting block 12 is symmetrically opened on the upper part of the inner surface of the pressure chamber 153, and a quick-connect component 155 connected to the connecting pipe 2 154 is fixedly connected to the upper end of the supporting block 12 at a position located above the connecting pipe 2 154.

[0048] Further, in the process of replenishing the medicine, in order to achieve the limit of the support frame 25, it is used to cooperate with the connecting component 15 and the buckling component 14 to replenish the medicine. Figure 5 The snap-fit ​​assembly 14 includes a wedge block 141 slidably connected to the inner surface of the adjacent slide groove 11, and a limiting groove 142 is symmetrically provided on the inner surface of the slide groove 11. The front and rear ends of the wedge block 141 are symmetrically fixedly connected with a slider 143 slidably connected to the adjacent limiting groove 142, and the end of the slider 143 away from the pressure chamber 153 is fixedly connected with a spring 144 fixedly connected to the inner surface of the limiting groove 142, and the side of the wedge block 141 close to the pressure chamber 153 is fixedly connected with a piston rod 145 slidably connected to the inner surface of the pressure chamber 153.

[0049] It should be particularly noted that the water pump 151 is a conventional pump body, which is a conventional device in the prior art. In the present invention, it is only used to provide insect repellent to the connecting pipe 152. The dust repellent in the connecting pipe 152 will first be filled in the pressure chamber 153, and the piston rods 145 on both sides will be squeezed away from each other. In the process of increasing the volume of the insect repellent in the pressure chamber 153, the wedge block 141 is squeezed by the piston rod 145 to move it toward the support frame 25, and the support frame 25 is gradually pressed to be fixed on the upper side of the liquid medicine storage box 5. In this process, the slider 143 continues to slide in the limit groove 142 and thereby compresses the spring 144, so that the wedge block 141 is reset after the subsequent medicine replenishment is completed.

[0050] When the piston rods 145 on both sides continue to move away until the connecting pipe 154 is connected to the pressure chamber 153, the insect repellent in the pressure chamber 153 will enter the quick-connect component 155 through the pressure chamber 153, and replenish the liquid medicine storage structure 4 through the quick-connect component 155;

[0051] Furthermore, when the liquid medicine storage structure 4 has completed replenishing the medicine, the water pump 151 stops operating, and the wedge block 141 is reset under the action of the spring 144. At this time, the piston rods 145 on both sides approach each other, and the remaining insect repellent in the pressure chamber 153 returns to the inner cavity of the liquid medicine storage box 5 through the connecting pipe 152.

[0052] Embodiment 3: Based on Embodiment 2, this embodiment further delivers the insect repellent in the medicine storage box 41 into the spray structure 3 through the supply pump 42, and sprays the insect repellent through the spray head 32. Furthermore, the insect repellent inside the medicine storage box 41 is continuously stirred through the action of the agitator 45 and the brewing component 46 to avoid precipitation of the insect repellent in the medicine storage box 41, thereby improving the spraying efficiency and avoiding clogging of the insect repellent in the supply pump 42 and the spray structure 3.

[0053] Specifically, to achieve the storage of insect repellent, refer to Figure 6 The medicine liquid storage structure 4 includes a medicine storage box 41 fixedly connected to the lower end of the connecting beam 24, a supply pump 42 connected to a plurality of spray structures 3 is fixedly connected to the top wall of the inner cavity of the medicine storage box 41, a plurality of brewing components 46 are linearly distributed and fixedly connected to the lower part of the inner surface of the medicine storage box 41, a medicine tonic component 44 is arranged on the bottom wall of the inner cavity of the medicine storage box 41, a locking component 43 which is symmetrically arranged on the lower end of the medicine storage box 41 and is engaged with the medicine tonic component 44, and an agitator 45 is fixedly installed symmetrically on the bottom wall of the inner wall of the medicine storage box 41.

[0054] The medicine storage box 2 41 is used to carry the insect repellent, and the supply pump 42 arranged on the top thereof can extract the insect repellent in the medicine storage box 2 41 and send it to each spray head 32 through the connecting pipe 4 35, so as to spray the insect repellent;

[0055] Furthermore, pheromone drugs will produce protein precipitates, which will redissolve after stirring, but will gradually clump in a static solution and eventually clog the pipeline. In this process, the solution is stirred by the stirrer 45, which has a built-in motor. The stirring blades driven by the motor stir the solution to avoid clumping.

[0056] Further, in order to achieve the stirring of the insect repellent and prevent it from settling, refer to Figure 7 The brewing component 46 includes a connecting tube three 461 which is fixedly connected to the inner surface of the connecting tube three 461 and is connected to the front end of the medicine storage box two 41. A mesh plate 462 is fixedly connected to the front end of the inner surface of the connecting tube three 461. A spring six 463 is fixedly connected to the front end of the mesh plate 462. A rubber ball 464 is fixedly connected to the front end of the spring six 463. The front diameter of the inner surface of the connecting tube three 461 is smaller than the diameter of the rubber ball 464. A plurality of through holes three 466 are linearly distributed on the lower part of the outer surface of the connecting tube three 461. The inner surfaces of the plurality of through holes three 466 are fixedly connected to valves 465.

[0057] The stirring of the stirrer 45 is ultimately less uniform, so it is arranged in the brewing component 46. During the flight of the drone, the wind pressure will compress the spring six 463 through the rubber ball 464, and the air will enter the connecting pipe three 461 through the holes on the mesh plate 462, and finally enter the medicine storage box two 41 through the valve 465 installed in the through hole three 466, thereby forming bubbles. The bubbles will float up under the action of buoyancy, and a large number of bubbles will float in the medicine storage box two 41, and follow the stirring action of the stirrer 45 to form more fragmented bubbles, thereby stirring the insect repellent in the medicine storage box two 41 to prevent it from precipitating.

[0058] Embodiment 4. Based on embodiment 3, this embodiment utilizes the function of support leg 431 to drive piston rod 2 434 to rise, and extracts hydraulic oil in sliding chamber 438 through the function of piston rod 2 434 and connecting tube 2 435, so that locking tongue 436 is separated from locking hole 437, releasing the limit on T-tube 446, and further pushing the closing plug 447 upward through the cooperation of top block 1551 and closing plug 447, and pressing the sliding ring 1554 down through the cooperation of sliding ring 1554 and T-tube 446, finally connecting through hole 1 1555 with through hole 2 444, thereby replenishing insect repellent in medicine storage box 2 41 and realizing rapid medicine replenishment.

[0059] Specifically, in order to cooperate with the medicine replenishing component 44 to replenish the insect repellent in the medicine storage box 2 41, refer to Figure 8 and Fig. 9 The quick-connect component 155 includes a connecting tube 1552 fixedly connected to the upper end of the supporting block 12, a top block 1551 fixedly connected to the upper end of the connecting tube 1552, a spring 1553 fixedly connected to the middle of the outer surface of the connecting tube 1552, a sliding ring 1554 slidably connected to the outer surface of the connecting tube 1552 fixedly connected to the upper end of the spring 1553, and a plurality of through holes 1555 are arranged in an annular distribution on the inner surface of the connecting tube 1552 corresponding to the position of the sliding ring 1554.

[0060] Further, in order to cooperate with the quick-connect component 155 to replenish the medicine, refer to Fig. 9The medicine tonic component 44 includes a limiting rod 441 distributed in an annular shape and fixedly connected to the bottom wall of the inner cavity of the medicine storage box 41. A floating plate 442 is slidably connected to the outer surfaces of the limiting rods 441. The lower end of the floating plate 442 is fixedly connected to a T-shaped tube 446 slidably connected to the through hole opened in the bottom wall of the medicine storage box 41. The horizontal part of the T-shaped tube 446 is located at the lower end of the medicine storage box 41, and the upper end of the T-shaped tube is fixedly connected to a spring 5 445 fixedly connected to the lower end of the medicine storage box 41.

The lower end of the spring 443 is fixedly connected to a closing plug 447 slidably connected to the inner surface of the vertical part of the T-shaped tube 446. The inner surface of the T-shaped tube 446 is provided with a plurality of through holes 444 distributed in an annular manner and connected to its outer surface.

[0061] The top block 1551 and the connecting tube 1 1552 are stationary. When the medicine replenishing component 44 is pressed down, the top block 1551 will enter the T-tube 446 and gradually press the closing plug 447 to make it rise, thereby connecting the through hole 2 444 with the T-tube 446, and the sliding ring 1554 will be blocked by the T-tube 446, so that the through hole 1 1555 connects the connecting tube 1 1552 with the T-tube 446, and then the medicine replenishing component 44 continues to descend until the spring 5 445 is compressed, and the inner cavity of the medicine storage box 2 41 is connected with the inner cavity of the connecting tube 1 1552 through the through hole 2 444 and the through hole 1 1555, thereby replenishing the medicine liquid in the inner cavity of the medicine storage box 2 41.

[0062] Further, in order to lock the medicine replenishing component 44 during the medicine dispensing process, refer to Fig.10 and Fig.11 The locking assembly 43 includes a fixed block 432 fixedly connected to the lower end of the medicine storage box 41, a piston rod 434 is slidably connected to the inner surface of the fixed block 432, the lower end of the piston rod 434 passes through the bottom wall of the inner surface of the fixed block 432, extends to the lower end of the fixed block 432 and is fixedly connected to a supporting leg 431, the inner surface of the supporting leg 431 is slidably connected to the outer surface of the fixed block 432, and the upper end of the supporting leg 431 is fixedly connected to a spring 433 fixedly connected to the lower end of the medicine storage box 41, a sliding cavity 438 connected to the adjacent connecting pipe 435 is formed on the inner surface of the through hole formed on the bottom wall of the medicine storage box 41, a locking tongue 436 is slidably connected to the inner surface of the sliding cavity 438, and a locking hole 437 matched with the locking tongue 436 is formed on the outer surface of the closing plug 447 at a position corresponding to the locking tongue 436.

[0063] When the support leg 431 falls on the supporting block 12, the medicine storage box 41 continues to descend to compress the spring 433, and the piston rod 434 rises relative to the fixed block 432. At this time, the distance between the piston rod 434 and the lower part of the inner cavity of the fixed block 432 gradually increases, so that the hydraulic oil in the sliding cavity 438 is extracted through the connecting pipe 435, so that the locking tongue 436 is driven by the negative pressure to gradually move away from the locking hole 437, and finally separated from the locking hole 437, thereby releasing the limit of the medicine supplement component 44;

[0064] Furthermore, when the support leg 431 leaves the upper end of the supporting block 12, the support leg 431 is reset under the action of the spring three 433, the piston rod two 434 is pressed downward relative to the inner cavity of the fixed block 432, the hydraulic oil enters the sliding cavity 438 through the connecting pipe two 435, and presses the locking tongue 436 to enter the locking hole 437 to engage, thereby limiting the position of the tonic component 44 to prevent the anti-insect liquid from leaking out of the tonic component 44 due to vibration during flight.

[0065] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
