[0002] A plant protection drone is an unmanned aerial vehicle used for the protection of agricultural and forestry plants. Powered by electricity, it generates lift and propulsion through multiple rotors, carrying a liquid storage tank and several nozzles for spraying pesticides. Its advantages include simple operation, good stability, low noise, and relatively low cost, making it suitable for operation in small areas such as farmland and orchards. For example, existing technology publication number CN206981038U describes a pesticide spraying nozzle and the plant protection drone itself.

[0003] However, the existing technology has the following problems when used: Since there are a lot of insects in the farmland environment, when the plant protection machine flies at low altitude above the farmland, the insects will be disturbed and fly around. Some insects are easy to clog the nozzles, resulting in uneven spraying of pesticides. The staff needs to fly the plant protection machine back to its original position to clean it and then spray again. The round trip takes a long time and thus leads to low work efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Refer to the instruction manual appendix Figure 1 -Appendix Figure 3 This utility model provides a spray nozzle for spraying pesticides on a plant protection machine, including a nozzle body 1. A protective component 2 is fitted on the outer wall of the nozzle body 1. The protective component 2 includes two semi-circular plates 21 fitted on the outer wall of the nozzle body 1. The bottom ends of the two semi-circular plates 21 are connected to the same protective net 22. The protective net 22 covers the outside of the nozzle body 1 and plays a filtering role. The protective net 22 is set in a hemispherical shape and the mesh size of the protective net 22 is 1-2mm, which can effectively prevent insects without affecting ventilation. The protective net 22 and the semi-circular plates 21 are both made of stainless steel. Stainless steel has strong corrosion resistance, which can improve the corrosion resistance and service life of the protected area.

[0025] Next, an arc-shaped cleaning brush 23 is provided on the outside of the protective net 22. Two semi-arc plates 21 are provided on opposite sides to support the rotation of the arc-shaped cleaning brush 23. The inner walls on both sides of the arc-shaped cleaning brush 23 are machined with slots 3 that are adapted to the rotating rods 24. One end of the rotating rod 24 is inserted into the slot 3 and is detachably connected to the arc-shaped cleaning brush 23 by bolts, which makes it easy for workers to disassemble the arc-shaped cleaning brush 23 for replacement.

[0026] One of the semi-circular plates 21 is provided with a drive assembly 25 for driving the rotating rod 24 to rotate. Specifically, the drive assembly 25 includes a motor 251, which is a Tarot 5008 motor. The top of the semi-circular plate 21 is machined with a mounting groove 252 for accommodating the motor 251 and the rotating rod 24. One end of the output shaft of the motor 251 is fixed to the rotating rod 24.

[0027] In actual use, the spray nozzle 1 sprays pesticide through the protective net 22 onto the plants. The protective net 22 filters flying insects as the spray nozzle 1 flies with the plant protection machine during non-spraying operations, preventing them from clogging the spray nozzle 1 and affecting subsequent pesticide spraying. At the same time, the protective net 22 protects the plants from collisions with the spray nozzle 1, thus extending the service life of the spray nozzle 1. After the spray nozzle 1 flies above the plants with the plant protection machine, the motor 251 drives the rotating rod 24 to rotate the arc-shaped cleaning brush 23 back and forth on the outside of the protective net 22. The arc-shaped cleaning brush 23 can scrape off the flying insects adhering to the surface of the protective net 22, and the flying insects adhering to the spray nozzle itself will also be scraped off, thus achieving automatic cleaning of both and improving the effectiveness of the spray nozzle 1 in spraying pesticide.

[0028] Refer to the instruction manual appendix Figure 4 -Appendix Figure 6 This utility model also provides a plant protection machine, including a plant protection drone 4. The bottom of the plant protection drone 4 is detachably connected to a liquid storage tank 5 for storing pesticide solution. The bottom of the liquid storage tank 5 is detachably installed with a guide rail 6. The guide rail 6 is provided with multiple sliders 7. The nozzle body 1 is detachably installed on the sliders 7.

[0029] The guide rail 6 has a through groove 8 machined at its rear end. Each slider 7 has a threaded rod 9 fixedly installed at its rear end. The threaded rod 9 passes through the through groove 8 and extends out of the rear side of the guide rail 6. Each threaded rod 9 is fixed to the guide rail 6 by a nut 10.

[0030] The storage tank 5 is provided with a sealing door 11 on one side. A liquid filling pipe 12 is fixedly inserted through the outer wall of the sealing door 11. The liquid filling pipe 12 is connected to the inside of the storage tank 5. A water pump 13 for delivering pesticide solution into the nozzle is detachably installed on the inner wall of the sealing door 11. The water pump 13 is a Haoying 8L water pump 12-14S. This water pump 13 can achieve a flow rate of 8L per minute, which is suitable for rapid spraying operations in large areas of farmland and can improve the efficiency of plant protection operations.

[0031] In actual use, the staff first injects the liquid into the storage tank 5 through the liquid filling pipe 12, and then screws on the sealing cap on the liquid filling pipe 12. The staff can then use the remote control of the plant protection drone 4 to control the plant protection drone 4 to fly above the plants. After that, the water pump 13 is used to draw the liquid and deliver it to multiple nozzle bodies 1. The liquid can then be sprayed using the nozzle bodies 1. Before spraying, the staff can also loosen the nut 10 on the threaded rod 9 to adjust the position of multiple nozzle bodies 1 on the guide rail 6, thereby adjusting the spraying range. Moreover, after use, the nozzle bodies 1 can be easily removed from the guide rail 6 for replacement.

[0032] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
