Description

Technical Field

[0001] This invention relates to the field of forestry protection technology, specifically to a spraying device for controlling pine wilt disease. Background Technology

[0002] Pine wilt disease is a disease of pine trees caused by the pine wood nematode, primarily transmitted by pine beetles. This disease is characterized by rapid spread, high mortality, and difficulty in control, causing severe damage to pine resources. Once infected, the water and nutrient transport channels of pine trees are rapidly blocked, leading to wilting and death. The large number of pine tree deaths caused by pine wilt disease each year not only disrupts the ecological balance but also results in significant economic losses.

[0003] Existing spraying devices for pine wilt disease control mainly employ methods such as injecting pesticides through drilling or large-area aerial spraying when treating pine wilt disease. While these methods can control pine wilt disease to some extent, the injection method is not very effective, especially for larger pine trees where large amounts of pesticide are required for control. Aerial spraying, on the other hand, causes the pesticide solution to spread during spraying, thus reducing its effectiveness.

[0004] In summary, the problem that the aerial spraying method used in some existing spraying devices for the control of pine wilt disease reduces the effectiveness of the pesticide solution has become a pressing issue in this field. Therefore, it is necessary to propose a spraying device for the control of pine wilt disease. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a spraying device for controlling pine wilt disease. By simultaneously driving the grinding, mixing, and spraying components through a drive unit, the device controls the spraying position and angle, thereby improving the accuracy and quality of spraying.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: A spraying device for treating pine wilt disease includes a processing box with a feed inlet at the top, and a controller electrically connected to a cloud processor and a cloud database. A U-shaped grinding plate is fixedly connected to the inner side wall of the processing box, and several grinding through holes are formed on the grinding plate. The grinding plate divides the interior of the processing box into a grinding chamber and a mixing chamber from top to bottom. The grinding chamber is connected to the mixing chamber through the grinding through holes. The grinding chamber is equipped with a grinding component for grinding solid medicinal materials into medicinal powder. The mixing chamber has a liquid inlet on its side wall and is filled with medicinal liquid. The mixing chamber is equipped with a mixing component for mixing the medicinal powder and the medicinal liquid.

[0007] A fixed frame is fixedly connected to one side of the processing box, and a drive component is fixedly connected to the inner side wall of the fixed frame. The controller is used to control the rotation of the output shaft of the drive component. The output shaft of one end of the drive component extends through the side wall of the processing box into the grinding chamber and rotates with the side wall of the processing box. The output shaft of the other end of the drive component extends through the side wall of the fixed frame to the outside of the fixed frame and rotates with the side wall of the fixed frame.

[0008] A rotating disk is coaxially fixed to the output shaft of the drive unit located outside the fixed frame. A hinge shaft is eccentrically fixed to the side of the rotating disk away from the output shaft of the drive unit. A hinge rod is hinged to the hinge shaft. A movable plate is hinged to the end of the hinge rod away from the hinge shaft. The side of the movable plate away from the hinge rod is vertically slidably connected to the outer wall of the fixed frame. A spraying component for spraying pesticides is provided on the side of the movable plate away from the fixed frame.

[0009] The technical principles of the above solution are as follows:

[0010] Workers place solid medicinal materials into the grinding chamber through the feed inlet, add liquid medicine into the mixing chamber through the liquid inlet, and activate the drive unit via the controller. At this time, the output shaft of the drive unit rotates, driving the grinding component, mixing component, and spraying component to operate.

[0011] The grinding component grinds the solid medicinal materials into powder. The powder falls through the grinding holes into the mixing chamber, where the medicinal liquid and powder are thoroughly mixed by the stirring action of the mixing component. Finally, the spraying device adjusts the spraying position and angle using the spraying component to spray the medicinal liquid.

[0012] The above approach has the following beneficial effects:

[0013] 1. In this invention, the driving component not only provides power to the grinding assembly, but also cleverly realizes the up-and-down movement of the spraying assembly, thereby effectively controlling the position and spraying angle of the spraying assembly, improving the accuracy and quality of spraying, ensuring that the liquid can be sprayed evenly to the target area, and achieving good prevention and control effects.

[0014] 2. This invention, through its built-in grinding and mixing components, enables the device to automatically grind solid medicinal materials into powder and thoroughly mix them with the medicinal liquid. This design not only improves the utilization rate of medicinal materials but also ensures the uniformity of the medicinal liquid composition, thereby enhancing the spraying effect.

[0015] 3. This invention enables remote monitoring and control of the device by electrically connecting the controller to the cloud processor, thereby improving the convenience and flexibility of operation and reducing the difficulty and cost of manual operation.

[0016] Furthermore, the grinding assembly includes a grinding rod that is coaxially and fixedly connected to the output shaft of the drive component. The end of the grinding rod away from the drive component is rotatably connected to the inner sidewall of the grinding chamber. Several grinding rollers are coaxially and fixedly connected to the grinding rod, and all grinding rollers are rotatably engaged with the grinding plate.

[0017] Beneficial effects: The design of several grinding rollers coaxially fixed on the grinding rod ensures the uniformity of the grinding action. As the grinding rod rotates, the uniform distribution of the grinding rollers on the grinding plate greatly reduces the accumulation of medicinal materials and local over-grinding during the grinding process, thereby improving grinding efficiency.

[0018] Furthermore, the mixing assembly includes a stirring rod rotatably fitted to the bottom wall of the mixing chamber, with several stirring blades fixedly connected to the stirring rod circumferentially along its side wall, and one end of the stirring rod away from the bottom wall of the mixing chamber extending through the grinding plate into the grinding chamber and rotatably fitted with the grinding plate.

[0019] A horizontal bevel gear is coaxially fixed to the end of the stirring rod away from the bottom wall of the mixing chamber, and a vertical bevel gear is coaxially fixed to the grinding rod. The horizontal bevel gear meshes with the vertical bevel gear.

[0020] Beneficial effects: The design of the stirring blades ensures thorough mixing of the medicinal liquid and powdered herbs within the mixing chamber. As the stirring rod rotates, the stirring blades generate a strong stirring effect within the mixing chamber, allowing the medicinal liquid and powdered herbs to combine evenly and fully.

[0021] Furthermore, the spraying assembly includes a limiting frame fixedly connected to the inner side wall of the fixed frame. The side wall of the limiting frame has an Ω-shaped limiting groove vertically. A limiting shaft slides vertically in the limiting groove. A limiting block is eccentrically fixedly connected to the limiting shaft. A limiting rod is eccentrically fixedly connected to the side of the limiting block away from the limiting shaft. A through groove is opened in the side wall of the fixed frame. The limiting rod extends to the outside of the fixed frame through the through groove. The limiting rod also extends through the moving plate to the outside of the moving plate and rotates with the moving plate.

[0022] A spray block is coaxially fixedly connected to one end of a limiting rod located outside the moving plate. A spray plate is fixedly connected to the top of the spray block. Several atomizing nozzles are fixedly connected to the top of the spray plate. All atomizing nozzles are connected to the mixing chamber.

[0023] Beneficial effects: By sliding the “Ω”-shaped limiting groove on the limiting frame with the limiting shaft, precise control of the limiting rod is achieved, thereby enabling precise control of the spraying position and angle.

[0024] Furthermore, a top cover can be detachably connected to the feed inlet.

[0025] Beneficial effects: The tight fit between the top cover and the feed inlet enhances the sealing of the device, which helps prevent external impurities from entering the device and maintains the purity of the medicine and the normal operation of the device.

[0026] Furthermore, the pesticide solution is selected from one or more of the following: abamectin preparation, thiamethoxam preparation, imidacloprid preparation, and green venetin preparation.

[0027] Beneficial effects: Combining one or more of the following formulations—avermectin, thiamethoxam, imidacloprid, and Green Vira—can leverage the synergistic effects of various agents to enhance control efficacy. Different agents can complement each other, strengthening the killing effect on pine wilt nematodes and their vector insects.

[0028] Furthermore, a base is fixedly connected to the bottom of the treatment box, and a camera is fixedly connected to one side of the base. The controller is used to receive the image information collected by the camera and send the image information to the cloud processor. The cloud processor analyzes the pine wilt disease situation in the current environment and determines whether spraying is necessary.

[0029] Beneficial effects: By utilizing advanced image recognition and machine learning technologies, the cloud processor can accurately assess the current status of pine wilt disease in the environment. Based on the analysis results, the cloud processor can intelligently determine whether spraying is necessary, as well as parameters such as the type, concentration, and frequency of spraying. This intelligent monitoring and decision-making process greatly improves the accuracy and efficiency of prevention and control efforts.

[0030] Furthermore, tracks are fixedly connected to the bottom of the base, and the controller is used to control the movement of the tracks.

[0031] Beneficial effects: The tracked design allows the spraying device to move stably under various terrain conditions, thus ensuring that the device can quickly reach the affected area and carry out timely and effective prevention and control work.

[0032] Furthermore, solar panels are symmetrically fixed to the side walls of the processing box.

[0033] Beneficial effects: Solar panels capture and convert solar energy into electricity, providing the device with a green and sustainable energy source. This reduces the spraying equipment's reliance on traditional electricity, thereby lowering the risk of damage due to power failures or instability. This helps extend the equipment's lifespan and reduces maintenance and replacement costs.

[0034] Furthermore, a backup power supply is fixedly connected inside the base.

[0035] Beneficial effects: The existence of a backup power supply reduces the possibility of the spraying device failing to operate normally due to insufficient power, thereby improving the overall reliability of the spraying device.

[0036] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0042] The following detailed description illustrates the specific implementation method:

[0043] Example 1:

[0044] As attached Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown: A spraying device for controlling pine wilt disease includes a treatment box 1 with a feed inlet at the top and a top cover 23 detachably connected to the feed inlet by threads. It also includes a controller electrically connected to a cloud processor and a cloud database. A base 2 is integrally formed at the bottom of the treatment box 1, and a track 3 is bolted to the bottom of the base 2. The controller controls the movement of the track 3. A camera 4 is screwed to one side of the base 2. The controller receives image information collected by the camera 4 and sends the image information to the cloud processor, which analyzes the current pine wilt disease situation in the environment and determines whether spraying is necessary.

[0045] The inner wall of the processing chamber 1 is integrally formed with a U-shaped grinding plate 5. The grinding plate 5 has several grinding through holes, dividing the interior of the processing chamber 1 from top to bottom into a grinding chamber and a mixing chamber. The grinding chamber is connected to the mixing chamber through the grinding through holes. The grinding chamber contains a grinding assembly for grinding solid medicinal materials into powder. The mixing chamber has a liquid inlet on its side wall and is filled with a medicinal liquid. The mixing chamber contains a mixing assembly for mixing the medicinal powder and the medicinal liquid. The medicinal liquid is selected from one or more of the following: abamectin preparation, thiamethoxam preparation, imidacloprid preparation, and green emamectin preparation.

[0046] A fixed frame 6 is welded to one side of the processing box 1. A drive component is bolted to the inner side wall of the fixed frame 6. The controller is used to control the rotation of the output shaft of the drive component. In this embodiment, a dual-head motor is selected as the drive component. The output shaft of one end of the dual-head motor extends through the side wall of the processing box 1 into the grinding chamber and is rotatably engaged with the side wall of the processing box 1. The output shaft of the other end of the dual-head motor extends through the side wall of the fixed frame 6 to the outside of the fixed frame 6 and is rotatably engaged with the side wall of the fixed frame 6.

[0047] The grinding assembly includes a grinding rod 7 that is coaxially bolted to the output shaft of a dual-head motor, such as... Figure 4 As shown, the left end of the grinding rod 7 is rotatably connected to the inner wall of the grinding chamber, and several grinding rollers 8 are integrally formed on the grinding rod 7 on the same axis. All grinding rollers 8 are rotatably engaged with the grinding plate 5.

[0048] The mixing assembly includes a stirring rod 9 rotatably fitted to the bottom wall of the mixing chamber, and a plurality of stirring blades 10 are welded circumferentially along the side wall of the stirring rod 9, such as... Figure 4 As shown, the upper end of the stirring rod 9 extends through the grinding plate 5 into the grinding chamber and rotates with the grinding plate 5.

[0049] A horizontal bevel gear 11 is coaxially fixed to the upper end of the stirring rod 9, and a vertical bevel gear 12 is coaxially fixed to the grinding rod 7. The horizontal bevel gear 11 and the vertical bevel gear 12 mesh.

[0050] like Figure 1 As shown, a rotating disk 13 is coaxially fixed to the output shaft of a dual-head motor located outside the fixed frame 6. A hinge shaft is eccentrically welded to the right side of the rotating disk 13. A hinge rod 14 is hinged to the hinge shaft. A movable plate 15 is hinged to the bottom end of the hinge rod 14. The left side of the movable plate 15 is vertically slidably connected to the outer wall of the fixed frame 6. A spraying component for spraying pesticides is provided on the right side of the movable plate 15.

[0051] The spraying assembly includes a limiting frame 16 welded to the inner wall of the fixed frame 6. The limiting frame 16 has a vertically formed "Ω"-shaped limiting groove on its side wall. A limiting shaft 17 slides vertically within the limiting groove, and a limiting block 18 is eccentrically welded to the limiting shaft 17. Figure 4As shown, a limiting rod 19 is eccentrically welded to the right side of the limiting block 18. A through groove is opened on the side wall of the fixed frame 6. The limiting rod 19 extends to the outside of the fixed frame 6 through the through groove. The limiting rod 19 also extends through the moving plate 15 to the outside of the moving plate 15 and rotates with the moving plate 15.

[0052] A spray block 20 is coaxially welded to one end of a limiting rod 19 located outside the moving plate 15. A spray plate 21 is integrally formed on the top of the spray block 20. Several atomizing nozzles 22 are fixedly connected to the top of the spray plate 21 by screws. All atomizing nozzles 22 are connected to the mixing chamber.

[0053] The specific implementation process is as follows: Workers add liquid medicine to the mixing chamber through the inlet and place solid medicinal materials into the grinding chamber through the feed inlet. Workers then start the dual-head motor via the controller. The output shaft of the dual-head motor rotates, driving the grinding rod 7 to rotate. The grinding rod 7 drives the grinding roller 8 to rotate together, grinding the solid medicinal materials into powder. The powder then falls into the mixing chamber through the grinding holes.

[0054] During rotation, the grinding rod 7 also drives the vertical bevel gear 12, which is fixedly connected to it on the same axis, to rotate. In turn, the vertical bevel gear 12 drives the horizontal bevel gear 11 to rotate, the horizontal bevel gear 11 drives the stirring rod 9 to rotate, and the stirring rod 9 drives the stirring blade 10 to rotate, so as to fully mix the medicinal powder and the medicinal liquid.

[0055] After the medicinal powder and liquid are fully mixed, the staff moves the spraying device to the forest area and retrieves and loads the movement route of the spraying device from the cloud database. Then, the staff starts the track 3 through the controller, so that it drives the spraying device to move along the predetermined movement route.

[0056] During the movement of the spraying device, camera 4 will collect image information of the current environment in real time and send the image information to the controller. The controller will then send the image information to the cloud processor. The cloud processor will make a real-time judgment on the current environmental situation. When an obstacle appears in front, the cloud processor will adjust the movement route of the spraying device in real time based on the image information of the current environment.

[0057] When the pine needles in the image appear yellowish-brown and the pine tree wilts, the cloud processor determines that the pine tree is suffering from pine wilt disease. At this time, the cloud processor sends a spraying signal to the controller, which controls the operation of the conveyor belt 3 to drive the spraying device to the root of the pine tree.

[0058] After the spraying device reaches the base of the pine tree, the controller controls the output shaft of the dual-head motor to rotate. The output shaft of the dual-head motor drives the rotating disk 13 to rotate, the rotating disk 13 drives the hinge shaft to rotate, the hinge shaft drives the hinge rod 14 to swing up and down, and the hinge rod 14 drives the moving plate 15 to move up and down.

[0059] During the up-and-down movement of the movable plate 15, it drives the limiting rod 19 to move up and down as well. The limiting rod 19 then drives the limiting block 18 to move up and down, and finally, the limiting shaft 17 to move up and down. Thanks to the vertically protruding "Ω"-shaped limiting groove design, the limiting shaft 17 is blocked by the limiting groove during its up-and-down movement. At this time, because the limiting rod 19 and the limiting block 18, as well as the limiting block 18 and the limiting shaft 17, are both eccentrically designed, when the limiting shaft 17 is blocked, the eccentrically positioned limiting block 18 will rotate, which in turn drives the limiting rod 19 to rotate. At this time, the limiting rod 19 drives the spray block 20 to rotate, the spray block 20 drives the spray plate 21 to rotate, and the spray plate 21 drives the atomizing nozzle 22 to rotate, thereby adjusting the angle and position of the atomizing nozzle 22.

[0060] After the angle and position of the atomizing nozzle 22 are adjusted, the medicine inside the mixing chamber will be sprayed out through the atomizing nozzle 22, so that the medicine is accurately sprayed on the roots and side walls of pine trees suffering from pine wilt disease, achieving targeted treatment.

[0061] This invention automatically grinds solid medicinal materials into powder using built-in grinding and mixing components, and then thoroughly mixes them with the liquid pesticide. This not only improves the utilization rate of the medicinal materials but also ensures the uniformity of the liquid pesticide composition, thereby enhancing the spraying effect. Simultaneously, this invention also improves the accuracy and quality of spraying by adjusting the spraying position and angle of the spraying components, ensuring that the liquid pesticide is evenly sprayed onto the target area to achieve good pest control results.

[0062] Example 2:

[0063] As attached Figure 1 , Figure 2 and Figure 3 As shown, the difference from Embodiment 1 is that solar panels 24 are symmetrically embedded in the side wall of the processing box 1, and a backup power cavity is opened inside the base 2. A backup power supply 25 is bolted and fixed inside the backup power cavity.

[0064] The specific implementation process is as follows: When the solar panel 24 is exposed to sunlight, it will charge the backup power supply 25, thereby storing backup energy for the spraying device and reducing the energy consumption of the spraying device.

[0065] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
