Abstract
Description
Technical Field
[0001] This utility model relates to the field of plant protection machine technology, specifically to an adjustable spraying structure for an unmanned plant protection machine. Background Technology
[0002] In recent years, with the rapid development of drone technology, drones have been increasingly widely used in agricultural aviation. A typical example is the use of unmanned aerial vehicles (UAVs) for agricultural and forestry plant protection operations. Using agricultural drones for low-altitude pesticide spraying is simple to operate and saves time and labor.
[0003] The existing unmanned agricultural drones cannot adjust the length of their spray pipes to suit the length and width of the farmland, resulting in low work efficiency. The spray pipes cannot automatically rotate outward to unfold or automatically retract, and the fixed length of the spray pipes is inconvenient for storage. Therefore, an adjustable spraying structure for unmanned agricultural drones is proposed to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide an adjustable spraying structure for unmanned agricultural drones to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable spraying structure for an unmanned plant protection drone, including a diagonal support frame.
[0006] The bottom end of the diagonal brace is fixedly connected to a first fixing ring, and a first spray pipe is connected through the middle of the first fixing ring.
[0007] Furthermore, an electric telescopic rod is fixedly connected to the top of the diagonal brace, and a bracket is fixedly connected to the top of the electric telescopic rod.
[0008] Furthermore, support plates are fixedly connected to both the front and rear ends of the bracket, and a first servo motor is fixedly connected to the top of the support plate.
[0009] Furthermore, a rotating shaft is fixedly connected to the output end of the first servo motor, and a fixing plate is fixedly connected to the top end of the rotating shaft.
[0010] Furthermore, a second fixing ring is fixedly connected to the middle top of the fixing plate, and a sleeve is fixedly connected to the middle of the second fixing ring.
[0011] Furthermore, the left end of the sleeve is connected to a second spray pipe, and several sealing rubber rings are fixedly connected to the inner wall of the left end of the sleeve.
[0012] Furthermore, an extension spray pipe is slidably connected to the middle of the sleeve, a limit ring is fixedly connected to the right end of the extension spray pipe, and a connecting ring is fixedly connected to the middle of the extension spray pipe.
[0013] Furthermore, a second servo motor is fixedly connected to the top of the fixed plate, and a ball screw is fixedly connected to the output end of the second servo motor.
[0014] Furthermore, the ball screw is threaded with a ball nut seat in the middle, and one end of the ball nut seat is fixedly connected to the connecting ring.
[0015] Furthermore, the first spray pipe, the second spray pipe, and the extension spray pipe are all fixedly connected with several electronic spray valves.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] By setting up an electric telescopic rod and bracket, when it is necessary to water taller plants, such as trees, the electric telescopic rod is activated, raising it upwards. This causes the servo motors at both ends of the bracket and the spraying components to rise together, making it suitable for plants of different heights and effectively expanding the applicability of the device. By setting up a servo motor, rotating shaft, fixed plate, second fixed ring, sleeve, second spray pipe, and extension spray pipe, activating the servo motor causes the rotating shaft to rotate, which in turn causes the fixed plate to rotate outwards along with the sleeve, second spray pipe, and extension spray pipe via the second fixed ring. This facilitates automatic unfolding and retraction, saving time and effort and effectively improving work efficiency. By setting up a servo motor, ball screw, ball nut seat, connecting ring, and extension spray pipe, when it is necessary to adjust the spray width, the servo motor is activated. The servo motor causes the ball nut seat to move left and right, and the connecting ring, which is fixedly connected to the ball nut seat, moves the extension spray pipe together, thereby adjusting the spray width, saving spraying time, and facilitating retraction without obstructing the opening of the car door.

[0027] Please see Figure 1-4This utility model provides a technical solution for an adjustable spraying structure for an unmanned plant protection drone: An adjustable spraying structure for an unmanned plant protection drone includes a diagonal support frame 1. A first fixing ring 2 is fixedly connected to the bottom end of the diagonal support frame 1, and a first spraying pipe 3 is connected through the middle of the first fixing ring 2. An electric telescopic rod 4 is fixedly connected to the top end of the diagonal support frame 1. By setting the electric telescopic rod 4 and a support frame 5, when it is necessary to water taller plants, such as trees, activating the electric telescopic rod 4 raises it, which in turn raises the first servo motors 7 at both ends of the support frame 5 and the spraying components, making it suitable for plants of different heights and effectively expanding the applicability of the device. The support frame 5 is fixedly connected to the top end of the electric telescopic rod 4, and support plates 6 are fixedly connected to both the front and rear ends of the support frame 5. A first servo motor 7 is fixedly connected to the top of the support plate 6. By setting up the first servo motor 7, the rotating shaft 8, the fixed plate 9, the second fixed ring 10, the sleeve 11, the second spray pipe 12, and the extension spray pipe 14, the first servo motor 7 is started. The first servo motor 7 causes the rotating shaft 8 to rotate, thereby causing the fixed plate 9 to drive the sleeve 11, the second spray pipe 12, and the extension spray pipe 14 to rotate outward together through the second fixed ring 10. This facilitates automatic unfolding and storage, saves time and effort, and effectively improves work efficiency. The output end of the first servo motor 7 is fixedly connected to the rotating shaft 8. The top of the rotating shaft 8 is fixedly connected to the fixed plate 9. The middle top of the fixed plate 9 is fixedly connected to the second fixed ring 10. The middle of the second fixed ring 10 is fixedly connected to the sleeve 11.
[0028] The left end of the sleeve 11 is connected to a second spray pipe 12. Several sealing rubber rings 13 are fixedly connected to the inner wall of the left end of the sleeve 11. An extension spray pipe 14 is slidably connected to the middle of the sleeve 11. A limit ring 15 is fixedly connected to the right end of the extension spray pipe 14. A connecting ring 16 is fixedly connected to the middle of the extension spray pipe 14. A second servo motor 17 is fixedly connected to the top of the fixing plate 9. By setting the second servo motor 17, ball screw 18, ball nut seat 19, connecting ring 16, and extension spray pipe 14, when it is necessary to adjust the spray width, the second servo motor 17 is started. The second servo motor 17 drives the ball nut seat 19 to move left and right, and the ball nut seat 18 moves with the ball screw 19. The fixed connecting ring 16 drives the extended spray pipe 14 to move together, thereby adjusting the spray width, saving spraying time, and facilitating storage without obstructing the opening of the car door. The output end of the second servo motor 17 is fixedly connected to a ball screw 18, and the middle thread of the ball screw 18 is connected to a ball nut seat 19. One end of the ball nut seat 19 is fixedly connected to the connecting ring 16. Several electronic spray valves are fixedly connected to the first spray pipe 3, the second spray pipe 12, the sleeve 11, and the extended spray pipe 14. One end of the second spray pipe 12 and the first spray pipe 3 are connected through a water pipe, and the other end of the first spray pipe 3 is connected to the water tank and another set of second spray pipes 12 through a three-way valve.
[0029] Before use, when watering taller plants, such as trees, is required, the electric telescopic rod 4 is activated. The electric telescopic rod 4 rises, which in turn raises the first servo motor 7 at both ends of the bracket 5 and the spraying assembly, making it suitable for plants of different heights and effectively expanding the applicability of the device. Then, the first servo motor 7 is activated, which causes the rotating shaft 8 to rotate, thereby causing the fixing plate 9 to rotate outward through the second fixing ring 10, along with the sleeve 11, the second spraying pipe 12, and the extension spraying pipe 14 for spraying. This facilitates automatic unfolding and storage, saving time and effort and effectively improving work efficiency. By setting up the second servo motor 17, ball screw 18, ball nut seat 19, connecting ring 16, and extension spraying pipe 14, when the spraying width needs to be adjusted, the second servo motor 17 is activated. The second servo motor 17 drives the ball nut seat 19 to move left and right, and the connecting ring 16, which is fixedly connected to the ball nut seat 19, drives the extension spraying pipe 14 to move together, thereby adjusting the spraying width, saving spraying time, and facilitating storage without obstructing the opening of the car door.
