Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles (UAVs), in particular to a UAV pesticide spraying device capable of spraying evenly. Background Art

[0002] Modern drone technology combined with pesticide spraying equipment can achieve advantages such as precise application of pesticides, reduced chemical waste, and improved operational efficiency.

[0003] Patent publication number CN218389487U discloses a drone pesticide spraying device that sprays evenly. The device includes a drone main body, a battery mounted on top of the drone main body, a solar panel mounted on top of the drone main body, a base fixedly connected to the bottom of the drone main body, and a water tank mounted inside the base. The drone pesticide spraying device, which sprays evenly, is equipped with a pinion drive motor, a large gear, a main stirring rod, a connecting plate, stirring blades, and a water tank. When the drive motor is started, the pinion rotates, which in turn drives the main stirring rod through the large gear, thereby driving the stirring blades to stir the liquid, evenly mixing the pesticide and water. This method also reduces the risk of bottom sedimentation. The device uses gear meshing to drive the device, ensuring stability during stirring and a robust structure that prevents uneven pesticide spraying.

[0004] As shown in the above technology, the above-mentioned drone has a large pesticide spraying area, and the material frame for temporarily storing pesticides needs to be directly replaced after working for a period of time. Currently, most drones are basically fixed with multi-layer bolts, and the disassembly steps are relatively cumbersome. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the utility model provides a drone pesticide spraying device with uniform spraying, which solves the problem that the main drones are basically fixed with multiple layers of bolts and the disassembly steps are relatively cumbersome.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a drone pesticide spraying device with uniform spraying, comprising:

[0007] A body frame, wherein a battery and a controller are arranged inside the body frame;

[0008] A power system, one side of which is fixedly connected to the surface of the body frame, and the power system is used to generate lift to move the entire drone upward;

[0009] A spraying assembly, the top of which is fixedly connected to the bottom of the body frame, and the spraying assembly is used to heat and spray the pesticide;

[0010] A support bracket, wherein the top of the support bracket is fixedly connected to the bottom of the body frame.

[0011] Preferably, the power system includes an arc-shaped mounting frame fixedly connected to the surface of the machine body frame, through grooves are provided on both sides of the surface of the arc-shaped mounting frame, and a positioning plate is movably connected to the inner wall of the arc-shaped mounting frame.

[0012] Preferably, an adjusting screw passes through the surface of the positioning plate, a fixing rod is fixedly connected to one side of the positioning plate, and a rotor is fixedly connected to one end of the fixing rod.

[0013] Preferably, the spray assembly includes a positioning frame fixedly connected to the bottom of the body frame, a heating block is fixedly connected to one side of the positioning frame, a limiting hole is opened at the bottom of the positioning frame, and an elastic pad is fixedly connected to the top of the inner wall of the positioning frame.

[0014] Preferably, the inner wall of the limiting hole is movably connected to a cylinder, and the top of the cylinder is fixedly connected to a connector plate.

[0015] Preferably, a storage box is fixedly connected to the bottom of the connector board, and a nozzle is connected to the bottom of the storage box.

[0016] The utility model provides a drone pesticide spraying device that sprays evenly. Compared with the existing technology, it has the following advantages:

[0017] (1) The drone pesticide spraying device with uniform spraying utilizes the setting of the spraying assembly. When disassembling the storage box, it is only necessary to pull up the plug-in plate, separate the cylinder from the limit hole, and then pull out the plug-in plate to disassemble the plug-in plate and the storage box as a whole. When working, the bottom of the elastic pad presses down the plug-in plate to fix it to prevent shaking. The relevant connection structure is simple and convenient for disassembly and maintenance. When spraying pesticides, a heating block is used to heat them at a low temperature, which ensures the fluidity of the viscous pesticides and enables the pesticides to be sprayed into the field more evenly.

[0018] (2) The drone pesticide spraying device sprays evenly, and the equipment that comes into contact with the pesticide using the power system must be cleaned and maintained after use. This is an important measure to ensure the safety of pesticide use and prevent pesticide residues from causing harm to the environment or human body. Rotor disassembly is generally carried out in cases of damage repair, cleaning, maintenance, replacement or upgrading. To disassemble the positioning plate, you only need to rotate the adjustment screw to separate it from the positioning plate to complete the disassembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The support bracket 4, the top of the support bracket 4 is fixedly connected to the bottom of the body frame 1. By utilizing the setting of the spray assembly 3, when disassembling the storage box 36, it is only necessary to pull up the connector plate 35, separate the cylinder 34 from the limiting hole 32, and then pull out the connector plate 35 to disassemble the connector plate 35 and the storage box 36 as a whole. During operation, the bottom of the elastic pad 33 presses down the connector plate 35 to fix it to prevent shaking.
