Description

Technical Field

[0001] This utility model relates to the agricultural field, and more specifically, to an agricultural spraying drone. Background Technology

[0002] In traditional rural areas, farmers have long relied on manual backpack sprayers to carry out pest and disease control tasks. This method has obvious drawbacks: on the one hand, farmers have to endure high physical labor; on the other hand, it is difficult to improve operational efficiency and cannot meet the development trend of large-scale and precision agriculture. In stark contrast, agricultural drones, as an innovative achievement of modern agricultural technology, have been remarkably effective in reducing the intensity of manual labor.

[0003] A search revealed that Chinese Patent Publication No. CN222005351U discloses "an agricultural spraying drone, comprising a drone body, a spraying assembly fixedly installed on the lower outer surface of the drone body, and arms and fan blades fixedly installed on the four outer surfaces of the drone body, with the fan blades located on the upper outer surface of the arms. A support frame is fixedly installed on the lower outer surface of the spraying assembly. The spraying assembly includes a base, a storage box, a fixed cover, a first connecting pipe, a water pump, a water outlet pipe, a second connecting pipe, a nozzle, a first connecting pipe connector, a hose, a solenoid valve, an annular connecting pipe, and a second connecting pipe connector. The base is fixedly installed on the lower outer surface of the drone body, and a storage box is fixedly installed on the lower outer surface of the base. This agricultural spraying drone, through its spraying assembly, achieves good atomization efficiency and a large spraying range when spraying pesticides, offering better application prospects." However, it still has the following drawbacks:

[0004] (1) In actual use, the device lacks a filtration process for the liquid medicine and water, which will cause impurities and particles to enter the nozzle along with the liquid, causing the nozzle to become clogged, reducing the efficiency of operation, and affecting the control of nozzle flow, which will have an adverse effect on the prevention and control of agricultural and forestry pests and diseases.

[0005] (2) In actual use, the nozzle of the device is located directly below the drone propeller. The wind force generated by the propeller will disrupt the atomized spray of the pesticide, resulting in uneven spraying. At the same time, the flat-bottomed storage box is not conducive to the water pump completely sucking out the liquid in the box. Therefore, an agricultural spraying drone is proposed. Utility Model Content

[0006] The purpose of this invention is to address the following issues in current devices: Firstly, the lack of a filtration system for the pesticide and water in practical use leads to impurities and particles entering the nozzle along with the liquid, causing blockage, reducing operational efficiency, and affecting nozzle flow control, thus negatively impacting the control of agricultural and forestry pests and diseases. Secondly, the nozzle is positioned directly below the drone's propeller, and the wind generated by the propeller disrupts the atomized pesticide spray, resulting in uneven spraying. Furthermore, the flat-bottomed storage tank design hinders the water pump from completely extracting the liquid from the tank.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] The present invention is as follows: an agricultural spraying drone, including a drone body, wherein the drone body is provided with a filter component for filtering pesticide liquid and impurities in water, and the filter component is provided with a spraying component for uniformly atomizing and spraying pesticide liquid.

A sliding groove is opened on one side of the medicine tank. A filter plate is slidably connected inside the sliding groove. A handle is welded to one side of the filter plate. A sealing strip is provided on the side of the medicine tank near the handle. The sealing strip works in conjunction with the filter plate. A liquid inlet is opened on the side of the medicine tank near the handle. An inlet pipe is fixedly connected inside the inlet. A manual rotary valve is fixedly installed on the periphery of the inlet pipe.

[0010] As a preferred technical solution of this utility model, the spraying assembly includes a liquid outlet hole opened at the bottom of the liquid tank, a conical plate welded inside the liquid outlet hole, a water pump passing through the bottom of the conical plate, an annular connecting pipe fixedly installed at the output end of the water pump, four water supply connecting pipes fixedly installed at one end of the annular connecting pipe, an atomizing nozzle fixedly installed at the other end of the water supply connecting pipe, and a windproof cover welded to the outer wall of the liquid tank.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0028] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0029] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0030] like Figure 1 As shown, this embodiment proposes an agricultural spraying drone, including a drone body 1, a filter assembly 2 for filtering pesticide liquid and impurities in water, and a spraying assembly 3 for uniformly atomizing and spraying pesticide liquid.

[0031] like Figure 6As shown, the filter assembly 2 includes four fixed posts 201 fixedly connected to the four corners of the bottom of the UAV body 1. A medicine tank 202 is fixedly connected to each of the four fixed posts 201. The medicine tank 202 stores medicine. A sliding groove 203 is provided on one side of the medicine tank 202. A filter plate 204 is slidably connected inside the sliding groove 203. The filter plate 204 filters impurities in the medicine. A handle 205 is welded to one side of the filter plate 204. A sealing strip 206 is provided on the side of the medicine tank 202 near the handle 205. The sealing strip 206 is used for sealing and works in conjunction with the filter plate 204. An inlet hole 207 is provided, and an inlet pipe 208 is fixedly connected inside the inlet hole 207. A manual rotary valve 209 is fixedly installed on the periphery of the inlet pipe 208. In use, the medicine is stored in the medicine tank 202, and the particulate impurities in the prepared medicine are filtered through the filter plate 204 to avoid impurities clogging the nozzle and causing a decrease in flow. The filter plate 204 can be removed by the handle 205 for cleaning and replacement to maintain the filter plate 204 and ensure its effectiveness. The sealing strip 206 is used to seal and prevent the medicine from leaking out. The medicine is put into the medicine tank 202 through the inlet pipe 208, and the inlet pipe 208 is closed by rotating the valve.

[0032] like Figure 4 and Figure 6 As shown, the spraying assembly 3 includes an outlet hole 301 at the bottom of the liquid tank 202. A conical plate 302 is welded inside the outlet hole 301 to collect the liquid and prevent residue. A water pump 303 is installed through the bottom of the conical plate 302 to deliver the liquid. An annular connecting pipe 304 is fixedly installed at the output end of the water pump 303. Four water supply connecting pipes 305 are fixedly installed at one end of the annular connecting pipe 304. An atomizing nozzle 306 is fixedly installed at the other end of the water supply connecting pipe 305 to atomize and spray the liquid. The outer wall of the liquid tank 202 is welded with a wind shield 307 to reduce the impact of propeller wind on the spraying. During use, the conical plate 302 facilitates the water pump 303 to completely extract the liquid from the liquid tank 202 to avoid residue. The water pump 303 provides power to transport the liquid through the water connection pipe 305. The liquid is then atomized and sprayed out through the atomizing nozzle 306. The wind shield 307 blocks the wind generated by the propeller of the UAV body 1, reducing the impact of propeller wind on the atomized liquid and making the liquid spraying distribution more uniform.

[0033] like Figure 6As shown, a motor 4 is fixedly installed on the top of the medicine tank 202, and a stirring rod 5 is fixedly installed on the output end of the motor 4. The stirring rod 5 passes through the medicine tank 202, and several stirring plates 6 are welded around the stirring rod 5. In use, the motor 4 provides power to drive the stirring rod 5 to rotate, which in turn drives the stirring plates 6 to move, thereby stirring the medicine in the medicine tank 202 to prevent the medicine from settling and mixing unevenly, and to ensure the efficacy of the medicine.

[0034] like Figure 3 As shown, an observation hole 7 is provided on the side of the medicine tank 202 away from the handle 205. An observation glass 8 is fixedly installed inside the observation hole 7. A protective layer 9 is fixedly connected inside the medicine tank 202. When in use, the user can easily observe the condition of the medicine inside the medicine tank 202 through the observation glass 8. The protective layer 9 isolates the medicine tank 202 from the medicine to prevent the medicine from corroding the medicine tank 202.

[0035] like Figure 6 As shown, four fixing rods 10 are welded to the bottom of the liquid tank 202. The four fixing rods 10 are arranged in an array at the bottom of the liquid tank 202. A receiving chamber 11 is welded to the bottom of the fixing rods 10. Several counterweights 12 are snapped into the inside of the receiving chamber 11. In use, the counterweights 12 are accommodated by the receiving chamber 11. The counterweights 12 can keep the center of gravity of the UAV body 1 at the bottom center position, reduce the turbulence during flight, and thus reduce the impact of the turbulent flow of the liquid on the flight of the UAV body 1.

[0036] like Figure 5 As shown, two O-shaped support plates 13 are fixedly installed on the bottom of the drone body 1. The two O-shaped support plates 13 are located on both sides of the liquid tank 202. During use, the O-shaped support plates 13 facilitate the take-off and landing of the drone body 1 and prevent the drone body 1 from being damaged due to accidental landing.

[0037] like Figure 3 and Figure 6 As shown, the liquid tank 202 is made of plastic, and the protective layer 9 is made of stainless steel. The plastic material is lightweight and durable, which can reduce the flight burden of the drone body 1. The stainless steel material has excellent corrosion resistance and can protect the outer liquid tank 202 from damage caused by liquid corrosion.

[0038] Specifically, when using this agricultural spraying drone: The pesticide solution is stored in the solution tank 202. Particulate impurities in the diluted solution are filtered through the filter plate 204 to prevent clogging of the nozzles and reduced flow. The filter plate 204 can be removed via the handle 205 for cleaning and replacement to maintain its effectiveness. A sealing strip 206 prevents pesticide leakage. Pesticide solution is added to the solution tank 202 through the inlet pipe 208, and the inlet pipe 208 is closed by rotating the valve (e.g., ...). Figure 6 As shown), during use, the conical plate 302 facilitates the complete extraction of the liquid medicine from the liquid medicine tank 202 by the water pump 303, preventing residue. The water pump 303 provides power, and the liquid medicine is transported through the water connection pipe 305. The liquid medicine is then atomized and sprayed out through the atomizing nozzle 306. The wind shield 307 blocks the wind generated by the propeller of the UAV body 1, reducing the impact of the propeller wind on the atomized liquid medicine and making the liquid medicine sprayed out more evenly (as shown). Figure 4 and Figure 6 As shown), during use, the motor 4 provides power to drive the stirring rod 5 to rotate, which in turn drives the stirring plate 6 to move, thereby stirring the medicine liquid in the medicine tank 202, preventing sedimentation and uneven mixing, and ensuring the efficacy of the medicine (such as...). Figure 6 (As shown).

[0039] All technical features in this embodiment can be freely combined according to actual needs.

[0040] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
