[0002] In modern agriculture, pest control devices are crucial for protecting crops from pests and improving yield and quality. The traditional method of manually spraying pesticides has drawbacks such as high labor intensity, low efficiency, and limited coverage. Although mechanical spraying can expand the coverage, it is difficult to operate in complex terrains and is prone to uneven spraying, resulting in pesticide waste and environmental pollution. With the progress of technology, the application of drones in agricultural plant protection has become increasingly popular, which has advantages such as high operation efficiency, labor saving, and precise pesticide application.

[0003] However, there are still some problems with existing drone spraying technologies. When spraying pesticides, the airflow in the air will blow the atomized drugs off course, causing the drugs to fail to be accurately deposited at the designated position, resulting in pesticide waste and environmental pollution. In addition, it is difficult for the drone spraying system to flexibly adjust the liquid medicine concentration according to the actual pest situation of the crops, and it is impossible to achieve precise pesticide application, which affects the control effect.

DETAILED DESCRIPTION OF THE INVENTION

[0027] Next, in combination with the accompanying drawings of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to the attached Figure 1 -attached Figure 7 , the embodiment of the present invention provides a pest control device for agricultural crop protection, including a machine body 1. A plurality of connecting arms 2 are installed on the outer side of the machine body 1. The bottom of the machine body 1 is detachably connected with an adjustment box 6. A storage box 5 is installed at the bottom of the adjustment box 6. A driving motor 7 is installed on the outer side of the adjustment box 6. The output end of the driving motor 7 is fixedly connected with a driving screw rod 904. A threaded sleeve is threadedly connected to the outside of the driving screw rod 904. A moving piston 903 is fixedly connected to the outside of the threaded sleeve. The upper side inside the adjustment box 6 is movably connected with a first rotating shaft 901 through a bearing. A driving gear 910 is fixedly connected to the outside of the first rotating shaft 901. Driving racks 902 are fixedly connected to both the left and right sides of the moving piston 903. The inner top wall of the storage box 5 is fixedly connected with an installation shell 906. A moving plate 907 is elastically connected to the inside of the installation shell 906 through a plurality of springs 909. A liquid discharge port 908 is opened on the lower surface of the installation shell 906. A winding roller 911 is rotatably installed inside the storage box 5. A rigid traction rope 905 is installed on the outside of the winding roller 911. A wind direction adaptive adjustment component is installed on the outer side of the connecting arm 2. The outside of the first rotating shaft 901 is meshed with the outside of the driving rack 902. One side of the driving screw rod 904 away from the driving motor 7 is movably supported by a bearing on the inner wall of the adjustment box 6. Two drain pipes 10 are installed at the bottom of the storage box 5. A torsion spring is installed on the outside of the winding roller 911, and the torsion spring is used to reset the rigid traction rope 905. One end of each of the two first rotating shafts 901 is fixedly connected with a first synchronous wheel 801. The outside of the first synchronous wheel 801 is connected with a second synchronous wheel 803 through a synchronous belt 802. The outside of the second synchronous wheel 803 is fixedly connected to the end of the driving screw rod 904.

[0029] Specifically, the connecting arm 2 is used to connect components such as the wind direction adaptive adjustment component. The adjustment box 6 is used to achieve precise spraying by adjusting the liquid medicine concentration. The storage box 5 is used to store the liquid medicine, providing the source of liquid medicine for spraying. The moving piston 903 moves along the direction of the medicine storage cavity under the action of the driving screw 904 and the thread sleeve, and at the same time drives the driving rack 902 to move, realizing the adjustment of the liquid medicine concentration. The spring 909 provides elastic force for the moving plate 907, enabling it to automatically reset after moving within a certain range. The moving plate 907 is connected to the winding roller 911 through a rigid traction rope 905. During the movement, the opening and closing of the liquid discharge port 908 are controlled, thereby controlling the flow of the liquid medicine. The liquid discharge port 908 is the channel for the liquid medicine to flow out of the mounting shell 906. The position change of the moving plate 907 will control the opening and closing of the liquid discharge port 908. The torsion spring provides the elastic force for the rigid traction rope 905 to reset, ensuring that the moving plate 907 can return to its original position at the appropriate time. The drain pipe 10 is the channel for the liquid medicine to flow out of the storage box 5. The wind direction adaptive adjustment component is used to automatically adjust the spraying angle according to the wind direction change, reduce the influence of the air flow on the sprayed liquid medicine, and improve the spraying accuracy.

[0030] During the spraying process of the machine body 1, monitoring is carried out through a camera. The camera monitoring system can judge whether the agricultural crop pest area is too severe.

[0031] When it is recognized that the agricultural crop pest area is too severe, the driving motor 7 is started. The driving motor 7 drives the rotating driving screw 904 to move the thread sleeve on its surface, and then drives the moving piston 903 to move. The movement of the moving piston 903 causes the driving rack 902 at the medicine storage cavity to rotate, and the driving rack 902 drives the driving gear 910 to rotate. Driven by the rotating shaft one 901, the synchronous pulley one 801 rotates accordingly. The synchronous pulley two 803 is driven by the synchronous belt 802 to rotate, and then the winding roller 911 rotates. The winding roller 911 winds the rigid traction rope 905 on its surface, and the winding of the rigid traction rope 905 drives the moving plate 907 to slide on the inner wall of the mounting shell 906, and the spring 909 is compressed. When the moving plate 907 reaches the limit position and no longer blocks the bottom of the drain pipe 10, the liquid medicine in the medicine storage cavity flows into the adjustment box 6 through the drain pipe 10 and the liquid discharge port 908, increasing the drug concentration. When the drug concentration reaches the set value, the driving motor 7 rotates in reverse, the moving piston 903 returns to its original position, and the spring 909 rebounds to push the moving plate 907 back to its original position to block the drain pipe 10, preventing the high-concentration liquid medicine from continuing to flow into the adjustment box 6, ensuring precise adjustment of the liquid medicine concentration, and preventing over-concentration. When the camera monitoring system judges that the agricultural crop pest area is not too severe, the moving piston 903 moves to the water storage cavity position, introducing pure water into the storage box 5 to dilute the liquid medicine and reduce its concentration to meet different pest control requirements.

[0032] Among them, the camera monitoring system includes the following modules:

[0033] The camera module is used to collect farmland image information and can monitor the growth status of crops and the occurrence of pests and diseases.

[0034] The data transmission module is responsible for transmitting the image data collected by the camera to the monitoring platform, using wired or wireless networks to meet the requirements of real-time high-definition video transmission.

[0035] The intelligent analysis module uses AI technology to analyze the image data, can identify the growth status of crops, the occurrence of pests and diseases, and the types and quantities of pests, etc., providing a basis for precise prevention and control.

[0036] The remote control module allows users to remotely control the pan-tilt and lens of the camera through mobile phones or computers, adjust the shooting angle and focal length, etc., facilitating the viewing of detailed conditions in different areas of the farmland.

[0037] The data storage module is used to save the image and video data collected by the camera, providing cloud and local storage solutions.

[0038] The pest and disease identification module, based on AI algorithms, automatically identifies signs of pests and diseases, timely reminds managers to take prevention and control measures to reduce losses.

[0039] The wind direction adaptive adjustment component includes an electric telescopic rod 301 installed outside the connecting arm 2. The output end of the electric telescopic rod 301 is fixedly connected with a first moving ring 302. The middle side of the outside of the connecting arm 2 is hinged with an electric turntable 306. The bottom of the electric turntable 306 is provided with a mounting column 307. The outside of the mounting column 307 is rotatably installed with a second moving ring 304. The outside of the second moving ring 304 is hinged with a swing rod 303. The first moving ring 302 is slidably connected to the outer surface of the connecting arm 2. One end of the swing rod 303 away from the second moving ring 304 is hinged to the outer surface of the first moving ring 302. A wind speed meter 305 is installed at the end of the connecting arm 2. The wind speed meter 305 is used to measure the wind speed and wind direction in the working area of the storage tank 5, providing a basis for the wind direction adaptive adjustment component.

[0040] Specifically, the electric telescopic rod 301 drives the first moving ring 302 to move along the connecting arm 2 through telescopic actions, providing power for the direction adjustment of the liquid spraying head 405. The electric turntable 306 is used to drive the mounting column 307 to rotate, providing an additional rotational degree of freedom for the direction adjustment of the liquid spraying head 405. The second moving ring 304 drives the mounting column 307 to swing under the traction of the swing rod 303, thereby adjusting the direction of the liquid spraying head 405. The wind speed meter 305 is used to measure the wind speed and wind direction in the working area of the storage tank 5, providing real-time data support for the wind direction adaptive adjustment component.

[0041] During the spraying process of the machine body 1, the anemometer 305 detects real-time wind speed and wind direction data. According to these data, the electric telescopic rod 301 is activated, driving the first moving ring 302 to move along the outer surface of the connecting arm 2. During the movement, the bottom end of the swing rod 303 swings accordingly, and its traction force acts on the second moving ring 304 and the mounting column 307, prompting them to swing, and further adjusting the direction of the liquid spraying head 405 at an angle opposite to the wind direction.

[0042] When the anemometer 305 detects that the wind direction is due north and the wind speed is relatively high, the liquid spraying head 405 deflects a certain angle towards the due south direction, so that the sprayed medicine can resist the disturbance of the airflow and accurately fall into the target area.

[0043] Specifically, the wind direction adaptive adjustment component is applied in the wind direction adaptive adjustment system, and the wind direction adaptive adjustment system includes the following modules:

[0044] are the modules involved in the wind direction adaptive adjustment system:

[0045] Wind speed and wind direction monitoring module: The core component is the anemometer 305, which is installed at the end of the connecting arm 2. It monitors the wind speed and wind direction in the operation area in real time and provides data support for system adjustment.

[0046] Power drive module: It includes the electric telescopic rod 301 and the electric turntable 306. The telescopic action of the electric telescopic rod 301 drives the first moving ring 302 to move along the connecting arm 2, providing linear motion power for the direction adjustment of the liquid spraying head 405. The electric turntable 306 is used to drive the mounting column 307 to rotate, providing an additional rotational degree of freedom for the direction adjustment of the liquid spraying head 405.

[0047] Mechanical transmission module: It is composed of components such as the first moving ring 302, the second moving ring 304, the swing rod 303 and the mounting column 307. The first moving ring 302 moves along the connecting arm 2 under the drive of the electric telescopic rod 301, and drives the second moving ring 304 and the mounting column 307 to swing through the swing rod 303, thereby realizing the adjustment of the direction of the liquid spraying head 405.

[0048] Control module, which is responsible for receiving the wind speed and wind direction data transmitted back by the anemometer 305, and controlling the actions of the electric telescopic rod 301 and the electric turntable 306 according to the preset control logic and algorithm to achieve precise adjustment of the direction of the liquid spraying head 405.

[0049] Data processing and feedback module, which processes and analyzes the data collected by the anemometer 305 in real time, extracts useful information, such as wind direction change trend, wind speed fluctuation, etc. At the same time, it feeds back the processed data to the control module.

[0050] Storage module, which is used to store relevant data during the operation of the system, such as wind speed and wind direction historical data, etc.

[0051] A liquid extraction pump 401 is installed on the outer side of the storage tank 5. The output end of the liquid extraction pump 401 is fixedly connected to a second transport pipe 403, and the input end of the liquid extraction pump 401 is fixedly connected to a first transport pipe 402. A temporary storage tank 404 is detachably connected to the top of the body 1. A plurality of connecting pipes 406 communicate with the lower surface of the temporary storage tank 404. A liquid spraying head 405 is installed at one end of the connecting pipe 406. One end of the first transport pipe 402 communicates with the bottom of the storage tank 5.

[0052] Specifically, when performing the operation of spraying pesticides on crops to kill insects, start the liquid extraction pump 401 outside the drone. After the liquid extraction pump 401 operates, it will extract the liquid medicine from the bottom of the storage tank 5 through the first transport pipe 402 and press the liquid medicine into the second transport pipe 403. Subsequently, the liquid medicine in the second transport pipe 403 is transported into the temporary storage tank 404 for temporary storage and buffering. When spraying is required, the liquid medicine in the temporary storage tank 404 is transported to each liquid spraying head 405 through a plurality of connecting pipes 406. Finally, the liquid spraying head 405 evenly sprays the liquid medicine on the crops to complete the operation of spraying pesticides to kill insects.

[0053] Two rotating shafts II 12 are movably connected to the inside of the storage tank 5 through bearings. A plurality of mixing blades 11 are fixedly connected to the outside of the rotating shafts II 12. One end of the rigid traction rope 905 is fixedly connected to the outside of the moving plate 907. The upper surface of the moving plate 907 is attached to the lower surface of the drain pipe 10. The drain port 908 is arranged directly above the rotating shaft II 12.

[0054] Specifically, when the liquid medicine flows into the inside of the regulating tank 6 through the drain port 908, it will drive the mixing blades 11 to rotate, thereby accelerating the mixing speed of the high-concentration potion or pure water and the liquid medicine.

[0055] Working principle: When specifically using this device, it includes the following operating principles:

[0056] First, the pre-mixed medicine enters the medicine storage cavity on one side inside the regulating tank 6 through a pipeline, and then pure water is injected into the water storage cavity on the other side inside the regulating tank 6. Start the liquid extraction pump 401 outside the body 1, transport the liquid medicine inside the storage tank 5 through the first transport pipe 402 to the second transport pipe 403, and then the liquid medicine inside the second transport pipe 403 is transported into the inside of 400 through a plurality of connecting pipes 406. And it is sprayed on the crops through the liquid spraying head 405 to perform the operation of spraying pesticides on the crops to kill insects;

[0057] During the spraying process of the machine body 1, it is monitored by a camera. The camera monitoring system determines whether the agricultural crop pest area is severely affected. If it is a severely affected area, the driving motor 7 is started. The driving of the driving motor 7 drives the driving screw 904 to rotate. Further, this drives the threaded sleeve to move along the outer surface of the driving screw 904, and then drives the moving piston 903 to move synchronously. At this time, the moving piston 903 moves along the direction of the medicine storage cavity. During the movement of the moving piston 903, it drives the driving rack 902 at the position of the medicine storage cavity to rotate. The movement of the driving rack 902 drives the driving gear 910 to rotate. Under the transmission action of the first rotating shaft 901, it drives the first synchronous pulley 801 to rotate synchronously. At this time, under the transmission action of the synchronous belt 802, the second synchronous pulley 803 drives the winding roller 911 to rotate. The rotation of the winding roller 911 drives the rigid traction rope 905 on its outer surface to wind. During the winding process of the rigid traction rope 905, it drives the moving plate 907 to move along the inner wall of the installation shell 906. At this time, the spring 909 is in a compressed state. When the moving plate 907 moves to the limit position, at this time, the moving plate 907 no longer contacts the bottom of the liquid discharge pipe 10. The liquid medicine located inside the medicine storage cavity sequentially passes through the liquid discharge pipe 10 and the liquid discharge port 908, and finally discharges into the inside of the adjustment box 6. In this way, the drug concentration inside the adjustment box 6 is increased. When the drug concentration reaches the threshold value, the output end of the driving motor 7 reverses, driving the moving piston 903 to return to its original position. The moving plate 907 returns to its original position under the elastic force of the spring 909 until it abuts against the feeding port position of the liquid discharge pipe 10, and the high-concentration liquid medicine no longer flows into the inside of the adjustment box 6. Under the same principle, when the camera monitoring system determines that the agricultural crop pest area is not severely affected, the moving piston 903 is moved to the position of the water storage cavity, and pure water flows into the inside of the storage tank 5 to reduce the liquid medicine concentration in the storage tank 5. In this way, the spraying concentration of the liquid medicine is accurately controlled, enabling the liquid medicine to more effectively cover the target crops and reducing the waste of pesticides;

[0058] During the spraying process of the machine body 1, it will be affected by wind. At this time, the anemometer 305 detects the real-time wind speed and wind direction data. By starting the electric telescopic rod 301, it drives the first moving ring 302 to move along the outer surface of the connecting arm 2. During the movement, it drives the bottom end of the swing rod 303 to swing. Under the traction force of the swing rod 303, it drives the second moving ring 304 and the mounting column 307 to swing, so that the liquid spraying head 405 swings along the angle opposite to the wind direction. For example, when the anemometer 305 detects that the direction is due north and the wind speed is high, the liquid spraying head 405 deflects towards the due south direction, so that the medicine can resist the disturbance of the air flow after being sprayed and accurately fall into the target area.

[0059] In summary, it is possible to adjust the liquid medicine concentration of the storage tank 5 according to the changes in the flight situation of the unmanned aerial vehicle and the crop pest situation, achieving precise control of the spraying concentration of the liquid medicine, enabling the liquid medicine to more effectively cover the target crops, reducing the waste of pesticides, and ensuring the rational use of drugs.
