[0026] The application will be described in detail below with reference to the accompanying drawings.

[0027] As Figures 1 to 8As shown, the present application provides a multi-scene unmanned aerial vehicle for agriculture, forestry, fishery and animal husbandry, which comprises a liquid storage tank 1, a horizontal moving support 3, a pesticide spraying rod 5, a driving device 6, a propeller 7, a folding wheel mechanism 8 and a device mounting rack 19. The liquid storage tank 1 is circular and hollow, and four liquid outlet interfaces 2 are uniformly distributed on the outer ring surface of the liquid storage tank 1. A delivery pump 9 is installed at each liquid outlet interface 2, and the liquid outlet interface 2 is rotatably connected to the horizontal moving support 3 around a vertical line. The horizontal moving support 3 is rotatably connected to one end of the pesticide spraying rod 5 around a horizontal line in the vertical direction. The hollow interior of the pesticide spraying rod 5 and the liquid outlet interface 2 are communicated through a hose 21, and the hose 21 passes through the internal through hole 22 of the horizontal moving support 3. The folding wheel mechanism 8 comprises a circular mounting member 10, a multi-stage telescopic rod and a folding rod 11. One end of the multi-stage telescopic rod is rotatably connected to the circular mounting member 10, and the other end of the multi-stage telescopic rod is rotatably connected to the folding rod 11. The other end of the pesticide spraying rod 5 is rotatably connected to the driving device 6. The driving shaft of the driving device 6 is fixedly connected to the propeller 7 and the circular mounting member 10. The device mounting rack 19 is fixed on the inner ring surface of the liquid storage tank 1, and a power source 4 is fixedly connected to the device mounting rack 19. The center of gravity of the power source 4 and the device mounting rack 19 is located at the center of the liquid storage tank 1.

[0028] In some embodiments, the driving device 6 is a double-output shaft motor. One output shaft of the motor is fixedly connected to the propeller 7, and the other output shaft is fixedly connected to the circular mounting member 10.

[0029] In some embodiments, the driving device 6 is two motors fixedly connected as one. The output shaft of the first motor 16 is fixedly connected to the propeller 7, and the output shaft of the second motor 17 is fixedly connected to the circular mounting member 10.

[0030] In some embodiments, a standby pesticide tank 12 is further included, which is in communication with the liquid storage tank 1 and is installed on the device mounting rack 11. A delivery pump is installed on the pipeline connecting the standby pesticide tank 12 and the liquid storage tank 1.

[0031] In some embodiments, the multi-stage telescopic rod comprises a first-stage telescopic rod 13, a second-stage telescopic rod 15 and a third-stage telescopic rod 14 connected in sequence. The first-stage telescopic rod 13 is rotatably connected to the circular mounting member 10, and the third-stage telescopic rod 14 is rotatably connected to the folding rod 11.

[0032] In some embodiments, a multi-rotor connecting rod 20 is further included. One end of the multi-rotor connecting rod 20 is rotatably connected to the liquid outlet interface 2 around a vertical line, and the other end of the multi-rotor connecting rod 20 is connected to the housing of the second motor 17. The output shaft of the second motor 17 is connected to the propeller 7.

[0033] In some embodiments, the material of the hose 21 is a stretchable rubber tube.

[0034] As Figure 1 shown, when the unmanned aerial vehicle of the present application is used for pesticide spraying mode, the liquid in the annular liquid storage tank 1 is transported to the cavity of the pesticide spraying rod 5 by the transport pump 9, and is sprayed to the area to be sprayed by the nozzle 18 on the pesticide spraying rod 5. The annular liquid storage tank 1 can be used as a tank for storing pesticides, and can also be used as a main part connected to the rotor, which reduces the weight of the existing unmanned aerial vehicle, and the liquid inside is beneficial to maintain the balance of flight. The pesticide spraying rod 5 is used as a connecting structure connected to the propeller 7, and also as a pesticide spraying structure. Compared with the existing linear area of the pesticide spraying structure extending on the unmanned aerial vehicle body, the pesticide spraying range of the present application is a circular area, and after the front two pesticide spraying rods complete spraying in the forward direction, the rear two pesticide spraying rods repeat spraying, and some transport pumps can be selected to be closed to change the pesticide spraying area, increase the pesticide spraying area and repeat the pesticide spraying.

[0035] The folding wheel mechanism 8 of the present application is shown in Figure 5 and Figure 6 , which includes a circular mounting member 10, a multi-stage telescopic rod and a folding rod 11 connected, one end of the multi-stage telescopic rod is rotatably connected to the circular mounting member 10, the other end is connected to the folding rod 11 rotatably connected, the multi-stage telescopic rod includes a first telescopic rod 13, a second telescopic rod 15 and a third telescopic rod 14 connected in sequence, the first telescopic rod 13 is rotatably connected with the circular mounting member 10, and the third telescopic rod 14 is rotatably connected with the folding rod 11. When the circular mounting member 10, the first telescopic rod 13, the second telescopic rod 15, the third telescopic rod 14 and the folding rod 11 are located on the same straight line, and the above straight line is parallel to the plane where the propeller is located, the folding wheel mechanism 8 can be used as another propeller, when the driving device 6 is a first motor 16 and a second motor 17 fixedly connected as a whole, the folding wheel mechanism 8 and the propeller 7 can form a double-layer counter-rotating propeller, improving the stability of the unmanned aerial vehicle.

[0036] The third telescopic rod 14 and the folding rod 11 of the folding wheel mechanism 8 of the present application are rotated to the limit close position, and the telescopic between the first telescopic rod 13, the second telescopic rod 15 and the third telescopic rod 14 can complete the support after the unmanned aerial vehicle lands, preventing it from directly falling on the ground position or plants which are not suitable for landing.

[0037] As Figure 2As shown, the four horizontal moving supports 3 of the UAV of the present invention rotate to be parallel to each other, and the spraying boom 5 rotates to be perpendicular to the horizontal moving supports 3. At this time, the spraying boom 5 is perpendicular to the ground, the telescopic boom is perpendicular to the ground and the folding boom 11, the relative rotation between the third-stage telescopic boom 14 and the folding boom 11 is perpendicular to each other, and the relative rotation between the first-stage telescopic boom and the circular mounting piece 10 is perpendicular to each other. The circular mounting piece 10 is driven to rotate by the drive device 6, and the entire folding wheel mechanism rotates, completing the overall walking action of the UAV on the ground. In this mode, the UAV can detect the soil and crop growth status through sensors, and the UAV can achieve the steering function by adjusting the rotation speed of different outer wheels. In this state, the UAV can move through the farmland and complete the detection of soil physicochemical components.

[0038] like Figure 4 As shown, when the drone of the present invention is used in grasping mode, the relative rotation between the three-stage telescopic rod 14 and the folding rod 11, the relative rotation between the first-stage telescopic rod and the circular mounting part 10, and the extension and retraction length of the multi-stage telescopic rods mimic finger movements to realize the grasping action of the folding wheel mechanism 8. The relative rotation between the horizontal moving bracket 3 and the spraying rod 5, and the relative rotation between the liquid outlet 2 and the horizontal moving bracket 3 mimic the arm controlling the grasping position. The drone attaches to the tree trunk, the sensors scan and detect the tree, and the folding wheel mechanism 3, which becomes a mechanical claw, can also perform sampling, such as picking fruits from high places or grasping samples in the field.

[0039] like Figure 3 As shown, when the UAV of the present invention is used for water landing, the rotation of the horizontal moving support 3 and the spraying rod 5 can be adjusted to be above the spraying tank 1. If there is no liquid in the storage tank 1, it acts as a suspending airbag, and the UAV can land directly on the water surface. If there is still liquid in the storage tank 1, it can be transported to the spare medicine tank 12 by the infusion pump. After the storage tank 1 is hollow, it can generate buoyancy to keep the UAV floating on the water surface without sinking. The propeller 7 rotates to provide thrust, and the sensor completes the water quality analysis underwater.

[0040] like Figure 8 As shown, one end of the multi-rotor linkage 20 of the UAV of the present invention is rotatably connected to the liquid outlet 2 around a vertical line, and the other end of the multi-rotor linkage 20 is connected to the housing of the second motor 17. The output shaft of the second motor 17 is connected to the propeller 7. When the multi-rotor linkage 20 is driven by the motor to rotate its connecting shaft until the propeller 7 and the folding wheel mechanism 8 are evenly distributed on the eight-part lines of the liquid storage tank, an octagonal aircraft can be formed. If two of the folding wheel mechanisms 8 are folded, a hexacopter aircraft can be formed to meet the requirements of different flight speeds and altitudes.

[0041] The rotatable connections of the present application are all driven by motors to rotate the connecting shafts, for example, the connection between the horizontal moving support 3 and the pesticide spraying rod 5, the connection between the liquid outlet interface 2 and the horizontal moving support 3, the connection between the three-stage telescopic rod 14 and the folding rod 11, and the connection between the first-stage telescopic rod and the circular mounting piece 10 are all provided with motors to drive the connecting shafts to rotate.

[0042] The multi-stage telescopic rod shown in the present application is an electric or steam-driven telescopic rod.

[0043] In the present application, the front refers to the forward direction of the flight of the unmanned aerial vehicle.

[0044] In the present application, the horizontal refers to the direction of the circular surface of the liquid storage tank of the unmanned aerial vehicle.

[0045] Since the innovation of the present application lies in the structure of the aircraft itself, the aircraft control system and the driving system are not included in the present application.
