Description

Technical Field

[0001] The utility model relates to the technical field of agricultural equipment, in particular to a telescopic pesticide spraying rod of a plant protection unmanned aerial vehicle. Background Art

[0002] Plant protection UAV, also known as unmanned aerial vehicle, is an unmanned aircraft used for agricultural and forestry plant protection operations. This type of unmanned aircraft consists of three parts: a flight platform (fixed-wing, helicopter, multi-axis aircraft), a navigation flight control, and a spraying mechanism. It can spray pesticides, seeds, powders, etc. through ground remote control or navigation flight control.

[0003] At present, most of the spraying poles of plant protection drones are of integrated design and fixed at the bottom of the drones. They cannot be flexibly replaced or repaired. In addition, most of the spraying poles of plant protection drones cannot be stored and are not convenient to carry. When spraying plants, due to the dense crowns of some plants, the drones cannot get close to the place where the spraying is required, which will result in the medicine cannot be accurately sprayed to the predetermined location. Utility Model Content

[0007] Preferably, the outer ring diameter of the ferrule matches the inner ring diameter of the outer tube to ensure the sealing between the hose and the outer tube, prevent leakage during spraying, and improve safety.

[0008] Preferably, the outer surface of the ferrule is movably connected to the inner wall surface of the outer tube, which has a simple process and ensures that the hose can be retracted into the inner part of the outer tube when the telescopic plant protection drone spraying rod is not in use, which is convenient for storage and does not affect normal use.

[0009] Preferably, the hose and the top of the outer tube are jointly provided with an electric push rod, the extended end of the electric push rod is installed on the outer surface of the hose through a bracket, and the fixed end of the electric push rod is installed on the outer surface of the outer tube through the bracket. When spraying, the extended length of the nozzle at the front end of the hose is adjusted by the electric push rod, which is convenient for adjusting the spraying position and improving the flexibility of the telescopic spray rod of the telescopic plant protection drone.

[0010] Preferably, a baffle is provided on the front end surface of the hose above the nozzle to protect the top of the nozzle and prevent the mist-like medicine from splashing upwards during spraying.

[0011] The beneficial effects of the utility model are:

[0012] 1. This telescopic plant protection drone spraying rod is used in conjunction with the upper splint and the pad, which makes it easy to install and disassemble the plant protection drone spraying rod, reducing the difficulty of the operation. In addition, the hose and outer tube splicing design is used, so that the telescopic plant protection drone spraying rod can be folded and stored when not in use, which is convenient to carry.

[0013] 2. This telescopic plant protection drone spraying rod adjusts the extension length of the nozzle at the front end of the hose through an electric push rod, which is convenient for flexible adjustment of the spraying position, so that the drone spraying rod can spray the plants more accurately.

[0020] like Figure 1-3 As shown, in this embodiment: a telescopic plant protection drone spraying rod comprises a hose 1, an outer tube 5 is arranged on the outer surface of the hose 1, a nozzle 3 is arranged at the front end of the hose 1, so that liquid medicine can be sprayed out of the hose 1, a clamping sleeve 7 is fixedly connected to the end surface of the hose 1, a clamping sleeve 8 is fixedly connected to the head end surface of the outer tube 5, and a nut 4 is threadedly connected to the outer surface of the clamping sleeve 8. When the drone spraying rod is used, the nut 4 is loosened to make the clamping sleeve 8 loosen the hose 1, the rear end of the hose 1 is pulled out, and then the nut 4 is tightened to make the clamping sleeve 8 clamp the outer surface of the hose 1, and the end surface of the outer tube 5 is fixedly connected to the material delivery pipe 6, and the stored The liquid medicine is transported to the inside of the spray rod, and the outer surface of the outer tube 5 is fixedly connected to a support ring 9, and the upper end surface of the support ring 9 is fixedly connected to a pad 12, and a threaded hole 13 is provided on the surface of the pad 12. Two hinged frames 15 are arranged at the edges on both sides of the top of the pad 12, and the surfaces of the two hinged frames 15 are commonly connected to a column 16, and the outer surface of the column 16 between the two hinged frames 15 is fixedly connected to an upper splint 11, and the surface of the upper splint 11 is movably connected to a screw 10. When installing the spray rod, flip the upper splint 11, the pad 12 fits with the upper splint 11, and the two arc grooves are combined into a circular hole, and the telescopic plant protection drone spray rod is installed on the unmanned bracket.

[0021] Furthermore, arc grooves are provided at corresponding positions on the top of the pad 12 and the bottom of the upper splint 11 between the threaded hole 13 and the articulated frame 15, and rubber anti-skid pads 14 are provided at the positions of the arc grooves. When the pad 12 and the upper splint 11 are in contact, the two arc grooves are combined into a circular hole, which is convenient for installing the telescopic plant protection UAV spray rod on the unmanned bracket. The rubber anti-skid pads 14 increase the friction and ensure the tightness of the installation of the telescopic plant protection UAV spray rod.

[0022] Furthermore, the outer diameter of the ferrule 7 matches the inner diameter of the outer tube 5, thereby ensuring the sealing between the hose 1 and the outer tube 5, preventing leakage during spraying, and improving safety.

[0023] Furthermore, the outer surface of the ferrule 7 is movably connected to the inner wall surface of the outer tube 5, and the process is simple, ensuring that the hose 1 can be retracted into the inner part of the outer tube 5 when the telescopic plant protection drone spraying rod is not in use, which is convenient for storage and does not affect normal use.

The extended end of the electric push rod 17 is installed on the outer surface of the hose 1 through a bracket, and the fixed end of the electric push rod 17 is installed on the outer surface of the outer tube 5 through a bracket. When spraying, the extended length of the nozzle 3 at the front end of the hose 1 is adjusted by the electric push rod 17, which is convenient for adjusting the spraying position and improving the flexibility of the telescopic spray rod of the plant protection drone.

[0025] Furthermore, a baffle 2 is provided on the front end surface of the hose 1 above the nozzle 3 to protect the top of the nozzle 3 and prevent the mist-like liquid medicine from splashing upwards during spraying.

[0026] The method of using this embodiment is: when using, please refer to Figure 1-3 When it is necessary to use a telescopic plant protection drone spraying rod, first flip the upper clamping plate 11 clockwise and then align the semicircular arc groove on the surface of the pad 12 with the bracket at the bottom of the drone, then close the upper clamping plate 11 counterclockwise to connect the upper clamping plate 11 and the pad 12 together, clamp the bracket at the bottom of the drone, then insert and tighten the screw 10, and finally pull the hose 1 outward. When the head end of the sleeve 7 is stuck at the bottom end of the clamping sleeve 8, tighten the nut 4, the hose 1 will be clamped, and spraying can be carried out. When spraying, due to the dense crowns of some plants, the drone cannot get close to the place where spraying is required. At this time, the extension length of the nozzle 3 at the front end of the hose 1 is adjusted by the electric push rod 17, so that the nozzle 3 is close to the place where spraying is required for spraying.

[0027] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
