Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 4 As shown, the present invention provides a spraying drone for rice planting, including a drone 1, a water tank 2 fixedly installed at the bottom of the drone 1, an arm 3 installed at each of the four corners of the drone 1, a pipe 4 fixedly installed at the bottom of the arm 3, and a nozzle 5 connected to the output end of the pipe 4.

A moving component 602 is fixedly connected to the top of the connecting block 601. Both sides of the connecting block 601 extend to the outside of the water tank 2 and are fixedly connected to a frame 603. Protective shells 604 are fixedly connected to the four corners of the bottom of the frame 603. The nozzle 5 is located inside the protective shell 604. A cleaning component 605 is fixedly connected to the top of the protective shell 604.

[0024] refer to Figure 3 The movable component 602 includes a bracket 602a, the bottom of which is fixedly connected to the top of the connecting block 601. A movable rod 602b is slidably connected to both the inner wall of the bracket 602a and the top of the connecting block 601. A circular block 602c is fixedly connected to the rear side of the movable rod 602b. A first motor 602d is provided on the back of the circular block 602c. The output end of the first motor 602d is fixedly connected to the inner wall of the circular block 602c.

[0025] As a technical optimization of this utility model, the movable component 602 can easily move the connecting block 601, the frame 603 and the protective shell 604, so that the protective shell 604 can be separated from the nozzle 5, making it convenient for the nozzle 5 to spray rice.

[0026] refer to Figure 4 The cleaning component 605 includes a second motor 605a, the bottom of which is fixedly connected to the top of the protective shell 604. The output end of the second motor 605a extends into the interior of the protective shell 604 and is fixedly connected to a fixing block 605b. A flexible brush 605c is fixedly connected to the surface of the fixing block 605b, and the top of the flexible brush 605c contacts the bottom of the nozzle 5.

[0027] As a technical optimization of this utility model, the cleaning component 605 can clean the bottom of the nozzle 5, preventing debris from adhering to the bottom of the nozzle 5 and causing blockage.

[0028] refer to Figure 3 A mounting bracket 7 is fitted onto the surface of the output end of the first motor 602d. The front of the first motor 602d is fixedly connected to the back of the mounting bracket 7. The round block 602c is located inside the mounting bracket 7. The back of the mounting bracket 7 is fixedly connected to the inner wall of the water tank 2.

[0029] As a technical optimization of this utility model, the fixed frame 7 can be used to position the first motor 602d and the circular block 602c, preventing them from shaking when rotating.

[0030] refer to Figure 3The surface of the first motor 602d is fitted with a housing 8, the front of the housing 8 is fixedly connected to the back of the fixing frame 7, and the top of the frame 603 is provided with a through hole 9 for use with the pipe 4.

[0031] As a technical optimization of this utility model, the housing 8 can limit the position of the first motor 602d and protect the first motor 602d. The through hole 9 can reduce the friction between the pipe 4 and the frame 603.

[0032] refer to Figure 4 A hollow protective tube 10 is fixedly connected to the top of the protective shell 604. The second motor 605a is located inside the hollow protective tube 10. The inner wall of the water tank 2 is provided with a movable groove 11 that cooperates with the connecting block 601.

[0033] As a technical optimization of this utility model, the hollow protective tube 10 can protect the second motor 605a, and the movable groove 11 can limit the position of the connecting block 601 and facilitate the movement of the connecting block 601.

[0034] The working principle and usage process of this utility model are as follows: In use, the user starts the first motor 602d. The output end of the first motor 602d drives the circular block 602c and the movable rod 602b to rotate clockwise. The rotation of the movable rod 602b causes the bracket 602a, connecting block 601, second motor 605a, and flexible brush 605c to move upwards. Because the flexible brush 605c is soft, it will not be damaged by friction with the nozzle 5 and pipe 4 when moving upwards. The upward movement of the connecting block 601 causes the frame 603 and protective shell 604 to move upwards. Move upwards to detach the protective shell 604 from the nozzle 5. At this point, the user can start the drone 1 to spray pesticides on the rice in the field. After spraying, the user can reverse the operation to protect the nozzle 5 with the protective shell 604. Then, start the second motor 605a. The output end of the second motor 605a drives the fixed block 605b and the flexible brush 605c to rotate. Because the flexible brush 605c is soft, it is convenient to rotate and clean the bottom of the nozzle 5 without damaging the nozzle 5. The nozzle 5 can then be cleaned.

[0035] In summary, this rice planting spraying drone uses a protective mechanism 6 to protect and clean the nozzle 5 of the drone 1, preventing deformation and damage to the nozzle 5 during transport. This solves the problem that the nozzles of spraying drones cannot be protected during use, and that the nozzles are easily subjected to external impacts and pressure during transport, leading to deformation and damage that affects the spraying effect.
