[0002] Currently, drone spraying needs to take into account different scenarios such as field operations, fruit tree operations, and sowing operations. Field operations require a small amount of water, so two centrifugal nozzles can meet the needs; fruit tree operations require a large amount of water, so the number of centrifugal nozzles needs to be increased to four; in order to reduce the invalid load of the drone in sowing operations, the centrifugal nozzles need to be removed.

[0003] A common way to increase the number of centrifugal nozzles on the market is to hang two at the tail arm position for field operations and two more at the nose arm position for fruit tree operations. The problem is that the pesticides atomized by the two centrifugal nozzles in the nose direction can easily contaminate the fuselage, affecting the normal operation of the FPV camera and radar, and also causing corrosion to the fuselage and cable connectors.

[0026] like Figure 1 As shown, this embodiment provides a centrifugal nozzle bracket structure, including a mounting seat 1, one end of the mounting seat 1 is connected to the bottom of the tail arm of the UAV, and the other end is connected to a mounting bracket 2, and the bottom of the mounting bracket 2 is detachably connected to at least one cantilever bracket 3, and a centrifugal nozzle assembly 4 is installed at the bottom of each cantilever bracket 3.

[0027] Specifically, the centrifugal nozzle support structure in this embodiment is installed in the direction of the tail arm, and will not pollute the fuselage when the aircraft flies forward. Compared with the prior art, adding a centrifugal nozzle in the direction of the nose arm can effectively eliminate the risk of contamination to the fuselage.

[0028] At the same time, the centrifugal nozzle support structure in this embodiment can take into account a variety of operation scenarios. A centrifugal nozzle support structure is respectively installed on the two tail arms of the UAV fuselage. When facing a field operation scenario, the two mounting brackets 2 of the centrifugal nozzle support structure are respectively quickly installed with a cantilever bracket 3, and the water demand for field operations can be met by two centrifugal nozzle assemblies 4; when facing a fruit tree operation scenario, the two mounting brackets 2 of the centrifugal nozzle support structure are respectively expanded to quickly install two cantilever brackets 3, that is, the number of centrifugal nozzle assemblies 4 is increased to four to meet the water demand for fruit tree operations; when facing a sowing operation scenario, the two mounting brackets 2 of the centrifugal nozzle support structure are quickly removed from the cantilever bracket 3 to reduce the invalid load of the UAV.

[0029] It should also be noted that the mounting bracket 2 in this embodiment can quickly support the installation of the cantilever bracket 3 according to application requirements, and there is no restriction on the number of cantilever brackets 3 connected to the mounting bracket 2, that is, a single mounting bracket 2 is not limited to supporting the installation of two cantilever brackets 3, and can also be expanded to a larger number.

[0030] See also Figure 2 A mounting groove 5 is provided on the side of the bottom of the mounting bracket 2 , and one end of the cantilever bracket 3 close to the mounting bracket 2 is inserted into the mounting groove 5 .

[0031] For details, see again Figures 2 to 4 A clamping block 6 is respectively provided on the two side walls of the mounting groove 5, and the two clamping blocks 6 cooperate with the mounting groove 5 to form a T-shaped groove 7. One end of the cantilever bracket 3 inserted in the T-shaped groove 7 is a T-shaped clamp 8 adapted to the T-shaped groove 7.

[0032] In this embodiment, the cantilever bracket 3 includes a mounting member 9, a disc member 10 and a connecting member 11, the mounting member 9 is used to be inserted and connected in the mounting groove 5, the disc member 10 is used to install the centrifugal nozzle assembly 4, and the connecting member 11 is used to connect the mounting member 9 and the disc member 10.

[0033] Specifically, the mounting member 9, the disc member 10 and the connecting member 11 are integrally formed.

The trapezoidal clamp block 12 has two side walls close to the T-shaped clamp 8 and is provided with a clamping groove 13 that cooperates with the two clamping blocks 6. A pressing block 14 that protrudes backwards is provided behind the two clamping grooves 13.

[0035] See also Figure 5 The front end of the mounting groove 5 is provided with two pressing blocks 15 for cooperating with the two pressing blocks 14 . The two pressing blocks 15 respectively press against the two pressing blocks 14 to enable the T-shaped clip 8 to be fixed in the T-shaped groove 7 .

[0036] During specific installation, as the T-shaped clamp 8 is gradually inserted into the T-shaped slot 7, the two pressing blocks 14 are pressed tightly by the two pressing blocks 15, and the cooperation between the two pressing blocks 15 and the two pressing blocks 14 can prevent the cantilever bracket 3 from detaching, thereby preventing the centrifugal nozzle assembly 4 from falling off; during disassembly, press the two pressing blocks 14 by hand and pull out the T-shaped clamp 8 upwards, so that the cantilever bracket 3 is detached from the mounting bracket 2, thereby removing the centrifugal nozzle assembly 4.

[0037] In this embodiment, a quick-release assembly structure is provided between the mounting bracket 2 and the cantilever bracket 3, so that an operator can quickly complete the disassembly and assembly of the cantilever bracket 3 to meet the switching between different working scenes.
