Abstract
Description
Technical Field
[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a plant protection irrigation UAV that facilitates quantitative spraying of pesticides. Background Technology
[0002] Unmanned aerial vehicles (UAVs) are also known as drones. Based on their application, UAVs can be divided into military and civilian uses. In the military field, UAVs are further divided into reconnaissance aircraft and target drones. In the civilian field, UAVs are increasingly used for agricultural irrigation. They are mainly used to spray pesticides or irrigate water to promote agricultural production and reduce labor costs. Therefore, there is a particular need for agricultural irrigation UAVs.
[0003] A search of existing Chinese patent technology reveals a device for "an agricultural irrigation drone" with publication number "CN221341060U". This device reduces the waiting time for the drone when returning to the water tank to replenish water after irrigation, thereby improving irrigation efficiency. However, when spraying irrigation liquid, the airflow generated by the drone's flight causes the sprayed liquid to drift with the airflow, resulting in uneven spraying and affecting the spraying effect. Utility Model Content
[0004] Therefore, it is necessary to address the problem that the sprayed pesticides will drift with the airflow generated by the drone's flight, resulting in uneven spraying and affecting the spraying effect. This necessitates providing a plant protection irrigation drone that facilitates quantitative pesticide spraying. The drone includes: a drone compartment containing a pump compartment, with a circuit compartment located at the lower end of the pump compartment. The circuit compartment is located inside the drone compartment, and a support frame is fixedly connected to the lower end of the drone compartment; a spraying mechanism installed on the inner top wall of the support frame, with its surface extending to the outside of the drone compartment; wherein the spraying mechanism includes an extended spraying component installed on the inner top wall of the support frame, one end of which is equipped with a camera, and the other end of which is connected to an angled spraying component. The surface of the angled spraying component penetrates the drone compartment and extends into the pump compartment.
[0005] In one embodiment, the extended spraying assembly includes a bottom rod fixedly connected to the inner top wall of the support frame. One end of the bottom rod is fixedly connected to the surface of the camera. A sliding groove is formed on the surface of the bottom rod away from the camera. A sliding block is slidably connected to the inner wall of the sliding groove. A sliding column is fixedly connected to the upper end of the sliding block. A scissor bracket is sleeved on the surface of the sliding column. A fixing bolt is provided at the upper end of the sliding groove. The lower end of the fixing bolt passes through the scissor bracket and is fixedly connected to the upper end of the bottom rod.
[0006] In one embodiment, the angled spraying assembly includes a connecting post connected to the end of the scissor lift away from the bottom rod. A fixing ring is fixedly connected to the lower end of the connecting post. A curved spray pipe is rotatably connected to the inner wall of the fixing ring. Two collars are fixedly connected to the surface of the curved spray pipe near the fixing ring. A nozzle is fixedly connected to one end of the curved spray pipe, and a corrugated pipe is connected to the other end of the curved spray pipe.
[0007] In one embodiment, the lower end of the sliding block extends below the bottom rod, and an electric push rod is provided on one side of the sliding block. The electric push rod is fixedly connected to the lower end of the bottom rod, and the telescopic end of the electric push rod is fixedly connected to the surface of the sliding block.
[0008] In one embodiment, the surface of the fixing ring is provided with a plurality of positioning holes, and the inner wall of the positioning holes is slidably connected with a positioning pin, the end of the positioning pin extending through to the other side of the collar.
[0009] In one embodiment, the other end of the bellows is connected to a conduit, the end of which, away from the nozzle, passes through the drone compartment and extends into the interior of the pump compartment.
[0010] In one embodiment, the surface of the scissor lift is provided with sliding holes, and the surface of the sliding post is slidably connected to the inner wall of the adjacent sliding holes.
[0011] Beneficial effects
[0012] The aforementioned plant protection irrigation drone, which facilitates quantitative pesticide spraying, extends the spraying end through its extended spraying component. This allows the sprayed pesticide to be kept away from the drone's airflow, ensuring that the sprayed pesticide can fall relatively evenly. This results in more uniform contact between the pesticide and the plant surface, improving the uniformity of the contact between the pesticide and the plant surface after spraying and ensuring the spraying effect.
[0013] The device can limit the spray angle through the set angle spraying component, so that the liquid will be adjusted according to the spray angle of the end of the curved spray pipe. The curved spray pipe rotates on the inner wall of the fixed ring, causing the spray angle of the nozzle to deviate. This causes the airflow of the drone to move away from the sprayed liquid, reducing the impact on the uniformity of the liquid spray and ensuring the spraying effect. Attached Figure Description

[0027] The following is combined with Figures 1-4 This invention describes a plant protection irrigation drone that facilitates the quantitative spraying of pesticides.
[0028] In one embodiment, a plant protection irrigation drone that facilitates quantitative pesticide spraying includes: a drone compartment 1, with a pump compartment 11 inside the drone compartment 1, and an electrical compartment 12 located at the lower end of the pump compartment 11. A support frame 2 is fixedly connected to the lower end of the drone compartment 1; a spraying mechanism 3, which is installed on the inner top wall of the support frame 2, and its surface extends to the outside of the drone compartment 1; wherein the spraying mechanism 3 includes an extended spraying component 31 installed on the inner top wall of the support frame 2, with a camera 33 installed at one end of the extended spraying component 31, and an angled spraying component 32 connected to the other end of the extended spraying component 31. The surface of the angled spraying component 32 penetrates the drone compartment 1 and extends into the interior of the pump compartment 1.
[0029] like Figure 1 , Figure 2 and Figure 3As shown, the extended spraying assembly 31 includes a bottom rod 311 fixedly connected to the inner top wall of the support frame 2. One end of the bottom rod 311 is fixedly connected to the surface of the camera 33. A sliding groove 312 is provided on the surface of the bottom rod 311 away from the camera 33. A sliding block 313 is slidably connected to the inner wall of the sliding groove 312. A sliding column 318 is fixedly connected to the upper end of the sliding block 313. A scissor bracket 315 is sleeved on the surface of the sliding column 318. A fixing bolt 316 is provided at the upper end of the sliding groove 312. The lower end of the fixing bolt 316 passes through the scissor bracket 315 and is fixedly connected to the upper end of the bottom rod 311.
[0030] The lower end of the sliding block 313 extends to the bottom of the bottom rod 311. An electric push rod 314 is provided on one side of the sliding block 313. The electric push rod 314 is fixedly connected to the lower end of the bottom rod 311. The telescopic end of the electric push rod 314 is fixedly connected to the surface of the sliding block 313. A sliding hole 317 is opened on the surface of the scissor lift 315. The surface of the sliding column 318 is slidably connected to the inner wall of the adjacent sliding hole 317.
[0031] In this embodiment, the device moves towards the camera 33 by the sliding block 313 against the inner wall of the sliding groove 312 through the telescopic end of the electric push rod 314. In turn, the sliding column 318 at the upper end of the sliding block 313 slides in the sliding hole 317 on the surface of the scissor frame 315. Since the scissor frame 315 is positioned by the fixing bolt 316, when the sliding column 318 moves, it absorbs the scissor frame 315 and gradually extends, so that the connecting column 321 gradually moves away from the drone compartment 1. This allows the sprayed agent to be kept away from the airflow generated by the drone's flight, ensuring the uniformity of spraying.
[0032] like Figure 1 , Figure 2 and Figure 4 As shown, the angle spraying assembly 32 includes a connecting post 321 connected to the end of the scissor lift 315 away from the bottom rod 311. A fixing ring 322 is fixedly connected to the lower end of the connecting post 321. A curved spray pipe 323 is rotatably connected to the inner wall of the fixing ring 322. Two collars 324 are fixedly connected to the surface of the curved spray pipe 323 near the fixing ring 322. A nozzle 325 is fixedly connected to one end of the curved spray pipe 323, and a corrugated pipe 326 is connected to the other end of the curved spray pipe 323.
[0033] The surface of the fixed ring 322 is provided with multiple positioning holes 328. The inner wall of the positioning hole 328 is slidably connected with a positioning pin 329. The end of the positioning pin 329 extends through to the other side of the collar 324. The other end of the bellows 326 is connected to a conduit 327. The end of the conduit 327 away from the nozzle 325 extends through the drone compartment 1 and into the interior of the pump compartment 11.
[0034] In this embodiment, the curved spray pipe 323 can be lifted and supported by the cooperation of the connecting column 321 and the fixing ring 322. The spraying angle of the curved spray pipe 323 can be controlled by the opening of the positioning hole 328 and the cooperation of the positioning pin 329, so as to maintain the uniformity of spraying the plants. Since the curved spray pipe 323 is curved, the liquid is not greatly affected by the airflow of the machine when spraying.
[0035] Working principle: The telescopic end of the electric push rod 314 drives the sliding block 313 to move towards the camera 33 on the inner wall of the sliding groove 312. In time, the sliding column 318 at the upper end of the sliding block 313 slides along with the sliding hole 317 on the surface of the scissor lift 315. Since the scissor lift 315 is positioned by the fixing bolt 316, the movement of the sliding column 318 causes the scissor lift 315 to gradually extend. The connecting column 321 gradually moves away from the agent sprayed by the drone compartment 1. The cooperation between the connecting column 321 and the fixing ring 322 lifts and supports the curved spray pipe 323. The cooperation between the positioning hole 328 and the positioning pin 329 controls the spraying angle of the curved spray pipe 323. When the curved spray pipe 323 sprays the liquid in a curved shape, it reduces the impact of airflow generated by the drone's flight and ensures the uniformity of spraying.
[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0037] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
