[0038] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0039] The embodiments described in this application are merely some embodiments, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application. The term "comprising" as used throughout the specification and claims is an open-ended term and should be interpreted as "including but not limited to".

The descriptions such as "first" and "second" used herein are used to distinguish different directions, structures, components, etc., and do not represent a sequential order. Furthermore, the embodiments described below are merely some embodiments, not all embodiments.

[0040] Figure 1 This is a perspective view of a spraying device provided in an embodiment of this application. Figure 2 Left view of a spraying device provided in an embodiment of this application. See also Figures 1 to 3 In one embodiment of this application, a spraying device assisted by wind power is provided. The spraying device includes: a body 1, a drive unit 2, a solution tank 3, a liquid supply device 4, and a spraying device 5. The body 1 can be considered as the main body or chassis of the spraying device, which is used to support or install other components.

[0041] The drive unit 2 is mounted on the body 1 and is used to drive the body 1 to move. The drive unit 2 includes, but is not limited to, a wheeled drive unit, a tracked drive unit, a footed drive unit, or a combination of wheeled and footed drive units.

[0042] For large-scale crop fields, field paths are usually provided between the ridges to facilitate the passage of equipment and workers. The corresponding crops are planted on the ridges. Spraying equipment that moves along the field paths can spray the crops on one or both sides of the ridges.

[0043] The solution tank 3 is detachably mounted on the machine body 1, and the spraying liquid is placed in the solution tank 3. The spraying liquid includes, but is not limited to: water, pesticide solution, growth regulator solution, fertilizer solution, etc.

[0044] Different fields may require different pesticide solutions. To facilitate quick switching between different work scenarios, the solution tank 3 is designed as a detachable modular unit, with different solution tanks 3 used for different pesticides. When the spraying equipment needs to spray another field, the user can remove the solution tank 3 and replace it with a suitable one to hold the corresponding pesticide. This not only allows for quick switching between work scenarios but also prevents residual pesticide from mixing with the previously used solution tank 3 after cleaning.

[0045] See Figures 1 to 4 The liquid supply device 4 is connected to the solution tank 3 via the liquid inlet pipe 6. The liquid supply device 4 draws spray liquid from the solution tank 3 through the liquid inlet pipe 6, pressurizes it, and then delivers it to the spraying device 5. Of course, to facilitate the disassembly and replacement of the solution tank 3, the liquid inlet pipe 6 is connected to the solution tank 3 via a quick-release connector.

[0046] In the technical solution provided in this application, the spraying device 5 can be set in various positions. The spraying device 5 can be set on the front or rear side of the machine body 1. As the spraying equipment moves, the spraying device 5 can spray the spray liquid onto the crops planted on the ridges on both sides of the field.

[0047] When spraying, the spraying device 5 mainly uses two forces to ensure the uniform spraying of the liquid. First, the liquid entering the spraying device 5 is pressurized, and after being sprayed out by the spraying structure 9, it undergoes initial atomization. Then, under the action of the fan assembly 8, the atomized liquid droplets are further refined, and the wind generated by the fan assembly 8 can then blow the liquid further.

[0048] See Figures 1 to 6 The spraying device 5 includes a blower assembly 8 and a spraying structure 9. The blower assembly 8 is mounted on the body 1, and the spraying structure 9 is located on one side of the blower assembly 8. The spraying structure 9 is connected to the liquid supply device 4 through a liquid outlet pipe 7. The high-pressure spraying liquid delivered by the liquid supply device 4 can be atomized through the spraying structure 9. The spraying direction of the spraying structure 9 includes at least one of the left, right, and top sides of the spraying device.

[0049] The body 1 is provided with at least one guide groove 12, and at least one spray head 92 on the spray structure 9 is provided corresponding to one of the guide grooves 12. The spraying direction of the spray head 92 matches the airflow path formed by the guide groove 12.

[0050] The position of the blower assembly 8 is related to the position of the spraying structure 9. The blower assembly 8 is positioned corresponding to the spraying structure 9 and can generate a high-speed airflow. At least one spray head 92 on the spraying structure 9 is located in the airflow path generated by the blower assembly 8. The direction of the airflow includes at least the left, right, and top sides of the spraying equipment. Of course, the direction of the airflow can also be a 360-degree circumferential direction of the spraying equipment.

[0051] Guided by the guide channel 12, the airflow generated by the fan assembly 8 flows along the guide channel 12, and ultimately disperses the atomized spray liquid generated by the spray head 92 located on the outside of the guide channel 12. The guide channel 12 can be used to concentrate the airflow, allowing the airflow generated by the fan assembly 8 to be blown further.

[0052] When the spraying device 5 is working, the airflow generated by the fan assembly 8 blows the spraying equipment around, which can assist the atomized spray liquid generated by the spraying structure 9 to spray and diffuse outward. Compared with the direct high-pressure atomization spraying of the spraying structure 9, the airflow can carry the atomized spray liquid to spray and diffuse to a farther area. In addition, the airflow can also carry the atomized spray liquid through the gaps between the dense crop leaves and spray it onto the crop leaves inside the field ridge, so that the spray liquid can be sprayed more evenly.

[0053] In addition, the spraying structure 9 usually has a fixed spraying range when spraying under high pressure, but the area covered by its spraying range is small, and even with multiple spray heads 92, it is not possible to effectively cover the crops on the ridges.

[0054] In the technical solution provided in this application, the airflow generated by the fan assembly 8 has a large coverage area. When the airflow diffuses outward, it can fully spread the high-pressure atomized spray liquid generated by the spraying structure 9, thereby effectively increasing the area that the spray liquid can cover. The airflow allows the spray liquid to be sprayed a long distance and the spraying area to be uniform. Under the action of the wind, the atomized spray liquid can enter the interior of the crop, and the entire crop can be evenly sprayed with the spray liquid.

[0055] Normally, as the spraying equipment moves forward, the spraying direction of the spraying liquid is opposite to the direction of travel of the equipment. This avoids spraying the liquid onto the body of the spraying equipment. See [link / reference]. Figures 1 to 6 In one embodiment provided in this application, along the traveling direction of the machine body 1, the liquid supply device 4 is located at the front of the machine body 1, and the spraying device 5 is located at the rear of the machine body 1. The solution tank 3 is located in the space between the liquid supply device 4 and the spraying device 5. The liquid supply device 4 includes, but is not limited to, a plunger pump, a centrifugal pump, an axial flow pump, etc. Figure 4 As shown, the liquid supply device 4 is driven by the motor 44.

[0056] Positioning the spraying device 5 at the rear of the machine body 1 not only facilitates spraying the liquid onto the crops but also prevents the liquid from falling onto the machine body 1. Positioning the liquid supply device 4 at the front of the machine body 1 helps balance the weight of the machine body 1. And placing the solution tank 3 in the middle of the machine body 1, filled with spraying liquid, improves the stability of the spraying equipment's center of gravity.

[0057] Furthermore, the body 1 includes a rear housing 11, and the fan assembly 8 includes a power assembly (located inside the rear housing 11) and fan blades 81. The rear housing 11 is located at the rear of the body 1, the power assembly is mounted on the rear housing 11, and the fan blades 81 are connected to the power assembly, with the fan blades 81 located on the rearward side of the rear housing 11. Multiple guide grooves 12 are provided on the side wall of the rear housing 11 facing the fan blades 81, extending from the center of the fan blades 81 outwards. The guide grooves 12 can convert airflow perpendicular to the rear housing 11 into an outwardly diffused direction (e.g., ...). Figure 5 (The direction indicated by the dashed arrow) will help the airflow assist the spraying liquid to spray outwards.

[0058] In one specific embodiment, multiple guide grooves 12 are evenly arranged around the outer periphery of the center of the fan assembly 8. Each guide groove 12 has an arc-shaped structure, with its first end close to the center of the fan assembly 8 and its second end extending away from the center of the fan assembly 8. The outward extension direction of the second end of the guide groove 12 is approximately parallel to the shell wall surface of the rear housing 11. The spraying structure 9 is located outside the second end of the guide groove 12, and the spraying direction of the spraying structure 9 is the same as the extension direction of the guide groove 12, both facing outward.

[0059] After encountering the guide groove 12, the airflow generated by the fan assembly 8 can flow along the arc-shaped guide groove 12. The direction of the airflow eventually becomes approximately parallel to the shell wall surface of the rear housing 11, so that the airflow can be blown to the outside of the rear housing 11.

[0060] In the technical solution provided in this application, the airflow direction is changed by the cooperation of the fan assembly 8 and the guide groove 12. In practical applications, setting up one fan assembly 8 and multiple guide grooves 12 arranged around the fan assembly 8 can satisfy the airflow blowing in multiple directions, with a simple structure and good performance.

[0061] See Figures 5 to 7 In one embodiment provided in this application, the spraying structure 9 includes at least one infusion pipe 91 and a spray head 92, with the spray head 92 disposed on the infusion pipe 91. One spray head 92 may be disposed on the infusion pipe 91, or multiple spray heads 92 may be disposed at intervals. The high-pressure spraying liquid delivered by the liquid supply device 4 can enter each spray head 92 through the infusion pipe 91, and is finally atomized and sprayed out by the spray head 92.

[0062] Furthermore, the outlet pipe 7 on the liquid supply device 4 is connected to the delivery pipe 91. A multi-port connector can be installed at the connection between the outlet pipe 7 and the delivery pipe 91, allowing multiple delivery pipes 91 to be connected to the outlet pipe 7 respectively. A valve body is installed between each delivery pipe 91 and the outlet pipe 7, so that the corresponding delivery pipe 91 can be opened or closed according to the actual spraying direction required.

[0063] See Figures 5 to 7 In one embodiment provided in this application, in order to improve the spraying efficiency of the spray head 92, the spray head 92 is provided corresponding to the guide groove 12 on the rear housing 11, and the spray head 92 is located outside the guide groove 12. The airflow output from the guide groove 12 can better disperse and blow the atomized spray liquid of the spray head 92 further, and the atomized spray liquid will be dispersed more evenly.

[0064] Furthermore, to prevent the spray head 92 from spraying the liquid onto the rear housing 11, the spray head 92 is positioned corresponding to the edge contour of the rear housing 11. This ensures that the spray direction of the spray head 92 is on the outside of the rear housing 11, preventing the liquid from easily adhering to the shell wall of the rear housing 11. For some corrosive liquids, the rear housing 11 is less susceptible to corrosion, resulting in a longer service life and preventing pollution.

[0065] As mentioned above, there are ridges on both sides of the field path, and crops are planted on the ridges. Therefore, the spraying equipment traveling on the field path sprays in the left and right directions of the machine body 1. Therefore, in the technical solution provided in this application, the spraying structure 9 is set at least on the left and right sides of the machine body 1.

[0066] Furthermore, to enable the spray liquid to spread further, the spraying structure 9 is also positioned on the upper side of the body 1, and multiple spray heads 92 on the spraying structure 9 spray outwards at an upward angle. Although the spray liquid sprayed by the spray heads 92 at an upward angle cannot directly act on the crops, the airflow can blow the atomized liquid higher, and then, as the liquid falls, it will spread outwards along the inclined direction and eventually land on crops farther away from the spraying equipment. This increases the coverage area of ​​the spraying structure 9, and the sprayed liquid can be effectively utilized, resulting in a higher utilization rate of the liquid.

[0067] See Figures 5 to 7 In one embodiment provided in this application, the spraying structure 9 is set along the circumferential direction of the fan assembly 8, corresponding to a region of one segment of the arc path. The spraying structure 9 forms a spraying area on at least one of the left, right and upper sides of the body 1.

[0068] Specifically, corresponding to the area of ​​the arc path on the left and right sides of the fan assembly 8 in the circumferential direction, the liquid delivery pipes 91 of the spray structure 9 are arranged in a straight line at the edge of the rear housing 11. Corresponding to the area of ​​the arc path on the upper side of the fan assembly 8 in the circumferential direction, the liquid delivery pipes 91 of the spray structure 9 are arranged in an arc shape at the edge of the rear housing 11, and multiple spray heads 92 are spaced apart on the liquid delivery pipes 91.

[0069] In one specific embodiment, the rear housing 11 is provided with a first infusion pipe 901 and a second infusion pipe 902. The first port 903 of the first infusion pipe 901 can be connected to the outlet port 71 of the outlet pipe 7, and the second port 904 of the second infusion pipe 902 can also be connected to the outlet port 71 of the outlet pipe 7. For example, the first infusion pipe 901 and the second infusion pipe 902 are connected to the outlet pipe 7 using a T-connector.

[0070] The first infusion conduit 901 and the second infusion conduit 902 each have a straight section and an arc section. The straight section is located on the left and right sides of the rear housing 11, and the arc section is located on the arc-shaped edge of the upper side of the rear housing 11. Multiple spray heads 92 are respectively provided on the straight section and the arc section.

[0071] See 1 to Figure 4 To improve the safety of the spraying equipment, the equipment also includes a protective cover 17. The protective cover 17 is located at the rear of the fan assembly 8 and is connected to the rear housing 11 via a bracket. A certain gap is provided between the protective cover 17 and the rear housing 11, and the spray head 92 is disposed in the gap. The protective cover 17 is also provided with a perforated protective net 171, which is positioned corresponding to the fan blades 81.

[0072] In agricultural production, spraying equipment is used for spraying different kinds of crops. Different crops may require different amounts of pesticides. In order to enable the spraying equipment to quickly adapt to spraying operations for different crops.

[0073] See Figure 7 In one embodiment provided in this application, the spray head 92 has at least a first spray head 921 and a second spray head 922 disposed opposite to each other. The spray structure 9 also includes a connecting pipe 923, one end of which is connected to the infusion pipeline 91, and the first spray head 921 and the second spray head 922 are rotatably connected to the other end of the connecting pipe 923. Specifically, one end of the connecting pipe 923 is connected to the infusion pipeline 91, and the other end extends in a direction close to the pipeline. The spray head 92, composed of the first spray head 921 and the second spray head 922, is connected to the end of the connecting pipe 923.

[0074] In addition, a pressure regulating chamber 924 is provided on the connecting pipe 923. The pressure regulating chamber 924 can adjust the pressure in the connecting pipe 923. When the pressure in the infusion pipeline 91 is insufficient, the lower pressure of the spray liquid can only act on the pressure regulating chamber 924 and will not act on the spray head 92. This can effectively prevent the spray liquid from leaking out of the spray head 92.

[0075] In the technical solution provided in this application, different nozzles can be switched by rotating the spray head 92 when different nozzles are needed. In addition, when one of the nozzles is damaged or leaking, different nozzles can be switched by rotating the spray head 92 to avoid pesticide contamination of the land.

[0076] Furthermore, rotating the spray head 92 allows the corresponding spray head to be turned on or off. When the first spray head 921 is rotated to face outwards from the machine body, the first spray head 921 is on, and the second spray head 922 is off. When the second spray head 922 is rotated to face outwards from the machine body, the second spray head 922 is on, and the first spray head 921 is off. This method not only simplifies the structure of the spray head 92 but also facilitates switching between the first spray head 921 and the second spray head 922.

[0077] Furthermore, in one embodiment provided in this application, the spray flow rate of the first nozzle 921 is different from that of the second nozzle 922 in terms of both spray flow rate and spray angle. Users can switch between nozzles with the desired spray flow rate and spray angle by rotating the nozzle 92 according to their specific usage needs.

[0078] After the cleaning robot completes its spraying operation, all nozzles need to be turned off to prevent leakage. In one specific embodiment, the first nozzle 921 and the second nozzle 922 are turned off when they rotate to a position perpendicular to the guide groove 12.

[0079] In another specific implementation, the ends of the first nozzle 921 and the second nozzle 922 are respectively provided with switch caps 925. By adjusting the switch caps 925, the flow rate and spray range of the first nozzle 921 and the second nozzle 922 can be changed. Specifically, the switch caps 925 are rotatably mounted on the nozzles, and rotating the switch caps 925 changes the flow rate and spray range of the first nozzle 921 and the second nozzle 922. This technical solution can further improve the adaptability of the spraying equipment. When facing crops with special spraying requirements, operators can precisely adjust the size of the flow channel and the spray range of the nozzles according to the actual situation to meet the needs of the operation.

[0080] In summary, the technical solution provided in this application allows the liquid supply device to deliver the spraying liquid from the solution tank to the spraying device. The pressure provided by the liquid supply device atomizes the spraying liquid, which is then sprayed outwards evenly under the action of the airflow generated by the fan assembly. The airflow allows for a long spraying distance and a uniform spraying area. Under the influence of the wind, the atomized spraying liquid can penetrate into the interior of the crop, ensuring that the entire crop is evenly sprayed with the liquid. Furthermore, the spray head includes multiple switchable nozzles, allowing users to switch between nozzles with the appropriate flow rate according to actual conditions.

[0081] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
