[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figures 1 to 4 As shown, the utility model provides a foldable spray rod of a plant protection UAV, including a rod body 1 that can be extended and arranged at the water spray outlet of the plant protection UAV. The rod body 1 is a pipe that can be connected end to end. By connecting to the water spray outlet of the plant protection UAV, the spray rod of the plant protection UAV can be extended, thereby extending its single spraying diameter.

[0028] In particular, the rod body 1 is connected to the water outlet of the UAV through a female connecting pipe 2, and a fastener 3 is provided on the female connecting pipe 2. The fastener 3 can fix the female connecting pipe 2 at the water outlet of the UAV so that the water outlet position can be extended to the end of the rod body 1. When the fastener 3 is closed, the female connecting pipe 2 and the water outlet of the UAV are in a sealed state. When the fastener 3 is opened, the female connecting pipe 2 and the water outlet of the UAV can slide relative to each other, and the water outlet of the UAV can be detached from the female connecting pipe 2 under the action of external force.

[0029] The end of the rod body 1 can be connected to a spray head.

[0030] When it is necessary to extend the spraying diameter of the UAV, remove the nozzle on the water outlet of the UAV, install the female connecting pipe 2 on the water outlet of the UAV, adjust the fastener 3, and fasten the female connecting pipe 2 at the water outlet of the UAV. At this time, the chamber in the rod body 1 is connected to the water outlet of the UAV, and the nozzle is installed at the end of the rod body 1 to extend the spraying diameter of the UAV.

[0031] After the spraying is completed, the fastener 3 is adjusted again, and the female connecting tube 2 and the water nozzle of the UAV can slide relative to each other. After the female connecting tube 2 is rotated, the rod body 1 can be folded inward to be parallel to the original nozzle of the UAV, thereby realizing the folding of the spray rod. The folding method is simple and does not require major improvements to the UAV, the UAV nozzle or the sprinkler head, thereby realizing the extension and folding of the spray rod of the plant protection UAV.

[0032] The device in the present invention is an external device for a plant protection UAV, which can be applied to a variety of plant protection UAVs and is convenient to connect and store.

[0033] Furthermore, the rod body 1 can be connected end to end, and theoretically its spraying diameter can be infinitely extended. Specifically, one end of the rod body 1 is provided with a female connecting pipe 2 that is installed in conjunction with the water spray port of the drone, and the other end of the rod body 1 is provided with a sub-connecting pipe 4 with the same structure as the water spray port. A chamber is provided inside the rod body 1, and the chamber is connected to the female connecting pipe 2 and the sub-connecting pipe 4.

[0034] A fastener 3 is provided on the female connecting tube 2, and the fastener 3 is used to fasten the connection between the female connecting tube 2 and the sub-connecting tube 4. When the fastener 3 is closed, the female connecting tube 2 and the sub-connecting tube 4 are in a sealed state. When the fastener 3 is opened, the female connecting tube 2 and the sub-connecting tube 4 can slide relative to each other, and the sub-connecting tube 4 can be detached from the female connecting tube 2 under the action of external force.

[0035] When it is necessary to extend the spraying diameter of the UAV, remove the nozzle on the water outlet of the UAV, install the female connecting pipe 2 on the water outlet of the UAV, adjust the fastener 3, and fasten the female connecting pipe 2 at the water outlet of the UAV. At this time, the chamber in the rod body 1 is connected to the water outlet of the UAV, and the nozzle is installed on the sub-connecting pipe 4 to extend the spraying diameter of the UAV.

[0036] When it is necessary to extend the spraying diameter of the UAV, remove the nozzle installed on the sub-connecting pipe 4 on the previous rod body 1, install the female connecting pipe 2 of the next rod body 1 on the sub-connecting pipe 4 on the previous rod body 1, adjust the fastener 3, and fasten the female connecting pipe 2 to the sub-connecting pipe 4 on the previous rod body 1. At this time, the chambers in multiple rod bodies 1 are connected to the water spray outlet of the UAV, and the nozzle is installed on the sub-connecting pipe 4 of the terminal rod body 1 to extend the spraying diameter of the UAV again.

[0037] A plurality of rod bodies 1 can be connected end to end.

[0038] After spraying is finished, the fastener 3 is adjusted again, the female connecting pipe 2 and the sub-connecting pipe 4 slide relative to each other, and after the rod body 1 is rotated, the rod body 1 can be folded inward to be parallel to the original nozzle of the drone, thereby realizing the folding of the spray rod. The folding method is simple and can be extended indefinitely in theory.

[0039] More than one sub-connecting tube 4 can be set on a rod body 1. Several sub-connecting tubes 4 are installed on the rod body 1, and the sub-connecting tubes 4 are connected to the chamber. The direction of the opening of the sub-connecting tube 4 is opposite to the direction of the opening of the mother connecting tube 2. The sub-connecting tubes 4 that are not connected to the mother connecting tube 2 can be connected to the nozzle, thereby achieving an increase in the spraying area.

[0040] The folding in this embodiment is manual. In order to make the folding operation and the fastening operation very simple, the fastener 3 includes an expansion tube 301 fixedly installed in the female connecting tube 2, and the bottom of the expansion tube 301 is fixedly installed on the inner wall of the female connecting tube 2. The sub-connecting tube 4 can radially pass through the expansion tube 301 to communicate with the chamber.

[0041] An inner ring 302 is fitted between the expansion tube 301 and the female connecting tube 2. The outer wall of the inner ring 302 is screwed to the outer wall of the female connecting tube 2 through a thread 303. The top of the inner ring 302 is connected to an outer ring 304, which protrudes from the female connecting tube 2.

[0042] When the outer ring 304 is rotated, the inner ring 302 rotates and moves toward the bottom of the expansion tube 301 under the guidance of the thread 303. The expansion tube 301 contracts and fixes the sub-connecting tube 4 passing through it, thereby fastening the sub-connecting tube 4 or the water outlet of the plant protection drone into the inside of the female connecting tube 2.

[0043] When the outer ring 304 is rotated in the opposite direction, the inner ring 302 rotates and moves toward the top of the expansion tube 301 under the guidance of the thread 303, the expansion tube 301 pops open, the female connecting tube 2 is rotated, the rod body 1 rotates and can be folded, and after the folding is completed, the outer ring 304 is rotated again to fix the rotation angle of the rod body 1.

[0044] If the rod body 1 needs to be disassembled, the mother connecting tube 2 needs to be pulled downwards, and then the sub-connecting tube 4 or the water outlet of the plant protection drone can be directly removed.

[0045] The fastener 3 has a simple connection and fastening structure, and is easy to fold and fasten. While fastening the pipe body together, it can also seal the joint, improve the sealing effect, and is easy to adapt to the water outlet pipes of various plant protection drones.

[0046] Furthermore, a conical surface 305 is provided at the top of the expansion tube 301 , and an inner conical surface 306 is provided at the bottom of the inner ring 302 . When the inner ring 302 rotates and descends, the inner conical surface 306 applies an inward contraction force to the conical surface 305 .

[0047] Furthermore, for easy operation, a plurality of rotating handles 307 are provided on the outer ring 304 .

[0048] Through the foldable spray boom of the plant protection drone of this embodiment, the spray boom of the plant protection drone can be extended and folded without making major improvements to the drone, drone nozzle or sprinkler head, and the operation method is simple.
