Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles (UAVs), and in particular to a precision spraying UAV. Background Art

[0002] Plant protection drones are composed of three parts: a flight platform (fixed-wing, helicopter, multi-rotor aircraft), a navigation flight control, and a spraying mechanism. Spraying operations are carried out through ground remote control or navigation flight control. They can spray pesticides, seeds, and powders. When spraying pesticides, plant protection drones mostly spray downwards, but in actual use, it will be found that the range of pesticide spraying is not accurate enough, and it is not possible to accurately spray pesticides in certain locations. As a result, it may take a longer time to spray these locations to ensure that the efficacy of the pesticide can take effect. However, this will result in a waste of pesticides, reducing the practicality of the equipment. Utility Model Content

[0025] The present invention is further described in detail below with reference to the embodiments:

[0026] Example 1

The medicine box 2 and the medicine nozzle 4 are connected together through a connecting hose 5. The adjustment box 3 is fixedly connected to the bottom of the medicine nozzle 4. The interior of the adjustment box 3 is movably connected with a swivel 6, and the internal circumferential array of the adjustment box 3 is movably connected with a baffle 7. The baffle 7 and the adjustment box 3 are rotatably connected together through a connecting rod 8. One end of the swivel 6 is fixedly connected to a breaking plate 604, and a hole 401 is provided at the bottom of the medicine nozzle 4.

[0028] In this embodiment, by bending the bending plate 604, the rotating ring 6 is driven to rotate inside the adjusting box 3, and the connecting rod 8 is driven to pull the baffle 7 to move, thereby adjusting the area of ​​the hole 401 blocked by the baffle 7, and then controlling the area of ​​the spraying agent, making it convenient for people to adjust the area of ​​the spraying agent according to different environments, improving the practicality of the equipment, and bringing convenience to people.

[0029] Example 2

[0030] like Figure 1-6 As shown, on the basis of embodiment 1, the utility model provides a technical solution: preferably, an active cavity 303 is opened inside the regulating box 3, the inner circumferential array of the active cavity 303 is fixedly connected to the support shaft 304, the inner circumferential array of the rotating ring 6 is opened with an arc-shaped slide 601, the support shaft 304 and the arc-shaped slide 601 are adapted, the support shaft 304 is slidably connected to the inside of the arc-shaped slide 601, the rotating ring 6 is movably connected to the inside of the active cavity 303 through the support shaft 304 and the arc-shaped slide 601, and one end of the regulating box 3 is opened with a slot 305 The slot 305 is communicated with the movable cavity 303, the breaking plate 604 is slidably connected to the inside of the slot 305, the bottom of the adjusting box 3 is provided with a through slot communicated with the movable cavity 303, the hole 401 is communicated with the movable cavity 303, the upper end of the movable cavity 303 is fixedly connected with the support platform 306, the upper end of the support platform 306 is fixedly connected to the medicine nozzle 4, the bottom circumferential array of the support platform 306 is fixedly connected with the first rotating shaft 307, the inside of the baffle 7 is provided with a first rotating groove 701, and the first rotating shaft 307 is rotatably connected to the inside of the first rotating groove 701.

[0031] In this embodiment, the support shaft 304 and the arc-shaped slide groove 601 can limit the rotating ring 6, so that the support shaft 304 can rotate, and the baffle 604 can be bent so that the baffle 604 can slide inside the slot 305, thereby driving the rotating ring 6 to rotate inside the movable cavity 303. The agent sprayed from the agent nozzle 4 can be sprayed out through the hole 401, and the baffle 7 will block the hole 401, thereby reducing the area of ​​the agent spraying, thereby more accurately spraying a certain position, thereby improving the practicality of the equipment. The baffle 7 is rotatably connected to the bottom of the support platform 306 through the first rotating shaft 307 and the first rotating groove 701.

[0032] Example 3

[0033] like Figure 1-6 As shown, on the basis of Example 1 and Example 2, the utility model provides a technical solution: preferably, the surface of the bottom of the baffle 7 is fixedly connected with a third rotating shaft 702, one end of the connecting rod 8 is rotatably connected to the outer wall of the third rotating shaft 702, and the connecting rod 8 is rotatably connected to the baffle 7 through the third rotating shaft 702. The inner circumferential array of the rotating ring 6 is fixedly connected with the support block 602, and the bottom of the support block 602 is fixedly connected with the second rotating shaft 603, and one end of the connecting rod 8 is provided with a second rotating groove 801, and the second rotating shaft 603 is rotatably connected to the inside of the second rotating groove 801.

The internal thread of the breaking plate 604 is engaged with the bolt 605, and the bolt 605 is slidably connected to the inside of the arc groove 302.

[0034] In this embodiment, when the swivel 6 rotates inside the movable cavity 303, it drives the connecting rod 8 to move, thereby pulling the baffle 7 to rotate around the first rotating shaft 307, thereby adjusting the area of ​​the hole 401 blocked, and then controlling the area of ​​the sprayed agent, making it convenient for people to adjust the area of ​​the sprayed agent according to different environments, improving the practicality of the equipment, and bringing convenience to people. When the bending plate 604 is bent and moved, it drives the bolt 605 to slide inside the arc groove 302, and rotating the bolt 605 can make the bolt 605 and the surface of the support plate 301 fit tightly, so that the bending plate 604 can be fixed, and then the swivel 6 drives the baffle 7 to be fixed, providing good stability.

[0035] Let’s talk about the working principle of this precision spraying drone in detail.

[0036] like Figure 1-6As shown, when the spraying area needs to be adjusted, first rotate the bolt 605 to loosen the fixation of the breaking plate 604, and then break the breaking plate 604 to rotate inside the movable cavity 303. At this time, it will drive the connecting rod 8 to pull the baffle 7 to rotate around the first rotating shaft 307, so as to adjust the area of ​​the hole 401 covered. After adjustment, rotating the bolt 605 can make the bolt 605 and the surface of the support plate 301 fit tightly, so that the breaking plate 604 can be fixed, and then the swivel 6 drives the baffle 7 to be fixed.

[0037] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
