Description

Technical Field

[0001] The utility model relates to the technical field of agricultural equipment, and in particular to a pesticide application device of a plant protection drone. Background Art

[0002] Plant protection drones are unmanned aircraft designed specifically for agricultural and forestry plant protection and are widely used in agriculture and forestry. They primarily consist of a flight platform, a navigation and flight control system, and a spraying mechanism. They use ground-based remote control or GPS flight control to precisely spray pesticides, seeds, powders, and other substances.

[0003] After searching, the Chinese patent application number 202020454821.3 discloses a plant protection drone spraying device, including a diverter pipe, and a plurality of dual-nozzle spraying assemblies are equidistantly fixed at the bottom of the diverter pipe to ensure efficient spraying by automatically switching the nozzles. In this plant protection drone spraying device, the dual-nozzle spraying assembly includes a conducting pipe fixed through the bottom of the diverter pipe, and a three-way electromagnetic reversing valve is fixed at one end of the conducting pipe away from the diverter pipe. The two output ends of the three-way electromagnetic reversing valve are fixed with connecting pipes, and the ends of the connecting pipes are fixed with nozzle bodies. When the spraying nozzle of the plant protection drone is blocked during continuous flight and affects uniform spraying, the in-use nozzle can be switched to ensure continuous, stable and uniform spraying, thereby avoiding uneven spraying after the nozzle is blocked, and effectively preventing the plant protection drone from flying back for maintenance and affecting efficient plant protection spraying. However, the above patent has the following shortcomings: 1. The diverter pipe used to install the spray nozzle in the device is a one-piece structure that cannot be folded, which takes up too much space during transportation; 2. The diverter pipe and the spray nozzle are easily deformed and damaged due to collisions during transportation. To address this problem, the present application proposes a new solution.

To switch to connection, after the first pipe 201, the second pipe 202 and the third pipe 203 are folded or unfolded, the locking head 706 on the screw 705 is tightened to make it press against the connecting plate 704, thereby completing the fixation between the connecting plate 704 and the second connecting seat 701 and the third connecting seat 702, thereby fixing the status of the first pipe 201, the second pipe 202 and the third pipe 203 to prevent them from rotating. The setting of the anti-slip washer 708 can prevent sliding between the locking head 706 and the connecting plate 704.

[0042] Specifically, the working principle of the plant protection drone spraying device is as follows: when in use, the box 101 is connected to the plant protection drone through the hanging plate 105 and bolts, and then connected to the drug delivery pump on the plant protection drone through the connecting pipe 3. When spraying, the first pipe 201, the second pipe 202 and the third pipe 203 are pushed out of the box 101 through the electric telescopic rod 4, so that the double-nozzle spraying assembly 5 is located outside the box 101, and the first pipe 201, the second pipe 202 and the third pipe 203 are unfolded through the first rotating joint 7 and the second rotating joint 8. The medicine pump and the connecting pipe 3 can supply medicine to the shunt pipe 2 and the double-nozzle medicine-applying assembly 5. After use, the first pipe 201, the second pipe 202 and the third pipe 203 are folded through the first rotating joint 7 and the second rotating joint 8.
