Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) technology, and specifically refers to an agricultural spraying UAV. Background Technology

[0002] Chinese invention patent application 2019110788095 discloses a novel pesticide spraying plant protection drone, including a body, a bottom mounting frame, a water tank body, a motor, and a compression spring. The bottom mounting frame is fixedly installed in the middle of the bottom of the body, and a reserved groove is embedded in the upper surface of the bottom mounting frame. The inside of the reserved groove is connected to a limiting block through a reset spring. The bottom of the bottom sliding rod is connected to a spray head.

[0003] This patent describes a method for installing spray nozzles by setting up horizontal fixing rods and bottom sliding rods on the horizontal fixing rods. The number of nozzles that can be installed in this structure depends on the length and number of horizontal fixing rods. In reality, the number of horizontal fixing rods that can be installed on a drone is limited. The horizontal fixing rods are set up on the basis of the drone itself, which makes the overall assembly of the drone complex and causes the nozzles on it to be clustered together, affecting the uniformity of spraying.

[0031] The present invention will be further described below with reference to specific embodiments:

[0032] An agricultural spraying drone includes a drone body, a water tank 2, and a main control component 3, such as Figure 1-4 As shown, a number of arms 11 are arranged around the outer edge of the main body of the drone. The outer end of the arms 11 is provided with rotors 12. The bottom of the main body of the drone is provided with a base 13. The water tank 2 is fixed on the main body of the drone. The main control component 3 is fixed on the water tank 2. The main control component 3 is connected to a power supply 5, a water outlet valve 4 and the rotors 12.

[0033] For details, please refer to the following: Figure 1 , 3 4. The drone in this patent is actually a rectangular frame 1 spliced ​​together from several profiles. The profiles have square cross sections and are fixedly connected to each other by welding. The interior of the frame 1 is used to install the water tank 2 and the main control component 3.

[0034] like Figure 4As shown, the frame 1 is also provided with several partition profiles 19, which separate a first mounting groove 191 and a second mounting groove 192. In this patent, there are two partition profiles 19, which are placed horizontally in the frame 1, thus separating a square first mounting groove 191, a second mounting groove 192, and a third mounting groove 193 in the frame 1; the water tank 2 in this patent is generally square, and it is fixed in the first mounting groove 191 by fasteners. The main control component 3 includes a circuit board, which is installed in a housing and fixed below the water tank 2. One side of the main control component 3 is connected to a water outlet valve 4, and several spray pipes 15 are connected to the water outlet valve 4.

[0035] A power supply bracket 194 is provided in a second mounting slot 192 next to the first mounting slot 191. The power supply 5 is a flat battery pack, which is vertically placed on the power supply bracket 194 and fixed. Figure 4 As shown, the power supply frame 194 is specifically a "U"-shaped frame assembled from tubular components, which is fixed to the frame 1 by welding. The battery pack can be positioned vertically on the frame 1 and secured by fasteners. The fasteners are generally screws, i.e., threaded seats are provided on the battery casing, and then screws are used to fix it to the power supply frame 194. Since the power supply 5 in this patent is a relatively flat battery pack, it can be placed vertically on the power supply frame 194 to reduce the lateral area occupied by the battery during installation, making the overall structure of the drone more compact.

[0036] The arm 11 is connected to the frame 1. Each arm 11 is provided with a downward-facing spray bracket 14. The water outlet valve 4 is connected to a spray pipe 15. The outer end of the spray pipe 15 is connected to the spray bracket 14. A downward-facing nozzle 16 is provided on the outer end of the spray pipe 15. The main control component 3 in this patent controls the rotor 12 to rotate for flight, and controls the water outlet valve 4 to control the nozzle 16 to discharge liquid.

[0037] like Figure 1As shown, the robotic arm 11 is long and rod-shaped. One end of the robotic arm 11 is provided with a tensioning adapter 17, which is fixed to the outer edge of the frame 1. The tensioning adapter 17 is provided with a tensioning element 171, which allows the robotic arm 11 to be rotatably connected to the frame 1 by loosening the tensioning element 171. The tensioning adapter 17 is fixed to the frame 1 with screws. In this patent, there are six robotic arms 11 in total, which are fixed in groups of three to the left and right ends of the frame 1 in a fan-shaped distribution, so that several robotic arms 11 are arranged around the frame 1. One end of the robotic arm 11 is provided with an adapter, which is rotatably connected to the tensioning adapter 17, so that it is rotatably connected to the frame 11. The tensioning element 171 is a locking shaft provided on the adapter of the robotic arm 11, and the other end of the locking shaft is provided with a locking nut. The robotic arm 11 can be positioned by rotating the locking nut against the tensioning adapter 17. Users can rotate the arm 11 through the tensioning adapter 17, thereby adjusting the angle of the arm 11 to a suitable position to obtain the best flight performance.

[0038] like Figure 2 As shown, the nozzle 15 is made of plastic and extends along the frame 1 to the spray bracket 14. It is then fixed to the frame 1 and the spray bracket 14 sequentially by a fixing bracket 111. In this patent, the spray bracket 14 is vertically positioned below the arm 11. A sleeve 143 is provided at the top of the spray bracket 14, which is fitted onto the arm 11 for connection. A fixing bracket 111 is provided on the sleeve 143. One end of the nozzle 15 is fixed to the arm 11 via the fixing bracket 111 and extends downwards to the spray bracket 14.

[0039] In fact, the spray support 14 is also equipped with a flow divider 141, which is T-shaped and fixed to the end of the spray support 14. The flow divider 141 has two flow divider ends 142. The spray pipe 15 has a forked portion 151, and the forked ends 152 of the forked portion 151 are respectively fixed to the flow divider ends 142 of the flow divider 141. The nozzles 16 are provided on the flow divider ends 142, and the nozzles 16 are set downwards. By setting the flow divider 141, the number of nozzles 16 is increased, thereby increasing the spray area.

[0040] In summary, this patent, by providing the spray bracket 14 on each arm 11, ensures that each arm 11 is equipped with a spray nozzle 16 for applying pesticides. This effectively utilizes the installation space on the arm 11, allowing the nozzles 16 to be evenly distributed across the drone, increasing the spraying area. Furthermore, the dispersed nozzles 16 ensure more uniform spraying. In addition, this patent allows for adjusting the position of the arm 11 to appropriately adjust the spraying position of the nozzles 16, enabling the drone to adapt to different spraying needs.

[0041] Furthermore, the frame 1 is also provided with a guide bracket 18, which has several openings. The nozzle 15 enters the guide bracket 18 through one side opening and extends outward from the other side opening to connect with the spray brackets 14 on each of the arms 11. Specifically, the guide bracket 18 is a tubular profile welded into the frame 1. The guide bracket 18 is used to accommodate the nozzle 15 and guide the nozzle 15 to connect with the corresponding arm 11, preventing the nozzle 15 from scattering on the UAV, and protecting the nozzle 15 through the guide bracket 18.
