Description

An agricultural sprayer with a solar photovoltaic structure and its working method Technical Field

[0001] This invention relates to the field of agricultural sprayers, and in particular to an agricultural sprayer with a solar photovoltaic structure and its working method. Background Technology

[0002] In crop cultivation, a crucial field management measure is the spraying of pesticides to control pests and diseases. Proper and rational pesticide application can reduce the cost of pest and disease control, improve effectiveness, and ultimately achieve high-quality, high-yield, and stable crop production. The purpose of spraying pesticides on crops is to control pests and diseases while also supplementing nutrients such as foliar fertilizers, thus achieving two benefits simultaneously. Pesticide application should be flexibly applied based on the patterns of pest and disease occurrence and the prevailing climatic conditions. For crops grown in greenhouses, the pesticides used for pest and disease control generally include water-based solvents and fumigants.

[0003] In existing technologies, when users drive sprayers to spray pesticides, the application relies entirely on the user's experience, resulting in uneven spraying, high energy consumption, and the easy inhalation of airborne pesticide components, thus affecting the user's health. Therefore, we provide an agricultural sprayer with a solar photovoltaic structure and its operating method. Summary of the Invention

[0004] The present invention addresses the technical problems of uneven spraying and energy consumption of current sprayers, as well as the potential harm to users' health caused by pesticides in the air. It provides an agricultural sprayer with a solar photovoltaic structure and its working method.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] An agricultural sprayer with a solar photovoltaic structure includes a base, two support rods, a movable box, a rotating rod, a water storage tank, a first water pump, a spray pipe, two nozzles, a drive motor, a rotating disc, a drive rod, a controller, four casters, a push handle, a rotating motor, an air duct, a fan, an activated carbon adsorption plate, a sterilization layer, a photovoltaic panel, a baffle, a cleaning brush, a sliding port, a battery, a dust removal pipe, and a dust removal port. The base is horizontally positioned. The push handle is positioned above the base and fixedly connected to it. The two support rods are vertically positioned above the base, with their lower ends fixedly connected to the top of the base. The movable box is inclinedly positioned above the base, between the two support rods, and to the side of the push handle. The two sides of the movable box are rotatably connected to the upper ends of the two support rods, and the rotation axis of the movable box is horizontally positioned and perpendicular to the tilt direction of the movable box. The rotating rod is located inside the movable box, along the tilt direction of the movable box, with both ends rotatably connected to the inner wall of the movable box, and its rotation axis coincides with the axis of the rotating rod. The rotating motor is a reversible motor, located on the side of the movable box near the push handle, and fixedly connected to the movable box. The rotating shaft of the motor passes through the movable box and is fixedly connected to one end of the rotating rod. The water storage tank is located inside the movable box and fixedly connected to the rotating rod. The first water pump is located inside the water storage tank and fixedly connected to the water storage tank. The spray pipe is a rigid pipe, one end of which is connected to the water inlet of the first water pump, and the other end extends out of the water storage tank. The spray pipe is fixedly connected to the water storage tank. Two nozzles are fixedly connected to the ends of the spray pipe outside the water storage tank, and the orientation of the two nozzles is along the rotation axis of the movable box. The push motor is located above the base and below the movable box, and is fixedly connected to the base. The rotation axis of the push motor is vertical and intersects the rotation axis of the movable box. The rotating disk is horizontally located above the motor and below the movable box. The axis of the rotating disk coincides with the rotation axis of the push motor, and the center of the rotating disk is fixedly connected to the rotation axis of the push motor. The push rod is vertically positioned above the rotating disk and below the movable box. It is located to the side of the rotating disk's axis of rotation, with its lower end fixedly connected to the rotating disk and its upper end in contact with the movable box. The upper end of the push rod is spherical. Four casters are located below the base and fixedly connected to it. The movement direction of the four casters is perpendicular to the rotation axis of the movable box. The duct is a straight pipe located on the side of the movable box near the push handle, below the rotating motor. The duct's axis is aligned with the inclined direction of the movable box, and the duct is fixedly connected to it. The fan is located inside the duct and fixedly connected to it. The activated carbon adsorption plate is located inside the duct, on the side furthest from the movable box from the fan, and fixedly connected to it. The sterilization layer is located on the inner wall of the duct, on the side of the activated carbon adsorption plate furthest from the movable box. The photovoltaic panel is arc-shaped, located above the movable box, and fixedly connected to it. The center of the arc of the photovoltaic panel coincides with the rotation axis of the movable box. The baffle is located above the base, between the movable box and the push handle, and is fixedly connected to the base.The cleaning brush is positioned on the side of the baffle near the movable box, fixedly connected to the baffle, and in contact with the photovoltaic panel surface. A sliding port is located on the baffle and fitted onto the air duct, its movement path adapted to the air duct's trajectory. A dust removal pipe is horizontally positioned between the movable box and the baffle, above the air duct, parallel to the movable box's rotation axis. The dust removal pipe is fixed and connected to the middle of the air duct, with its connection point between the dust removal pipe and the air duct located between the fan and the activated carbon adsorption plate. A strip-shaped dust removal port, parallel to the movable box's rotation axis, is located at the top of the dust removal pipe and connected to it. A battery is located on the top of the base and electrically connected to the photovoltaic panel. The controller is electrically connected to the drive motor, the first water pump, the rotation motor, the fan, and the battery.

[0007] When pesticide spraying is needed, the user moves the sprayer by pushing the handle. Simultaneously, the user controls the first water pump, blower, drive motor, and rotary motor via the controller. The first water pump sprays the pesticide from the storage tank through the spray pipe and two nozzles onto the farmland beside the sprayer. At the same time, the drive motor rotates a rotating disc, which in turn rotates a push rod. The push rod then rotates a movable box, causing the storage tank, spray pipe, and two nozzles to rise. After the rotating disc rotates the push rod half a turn, the push rod pushes the movable box in the opposite direction, causing the storage tank, spray pipe, and two nozzles to descend. This periodic raising and lowering of the two nozzles changes the spray height, resulting in more even spraying. Simultaneously, the rotary motor drives a rotating rod to reciprocate, which in turn rotates the storage tank, spray pipe, and two nozzles, causing the spray angle of the two nozzles to change periodically, further ensuring even spraying. This allows the spraying angle and spraying height of the sprayer to change periodically, thereby making the spraying more uniform.

[0008] The photovoltaic panels store the generated electricity in batteries. A rotating housing drives the photovoltaic panels to rotate back and forth, and cleaning brushes clean the dust off the surface of the photovoltaic panels, thereby improving the power generation efficiency of the photovoltaic panels.

[0009] Simultaneously, the fan draws outside air through the duct, fan, activated carbon adsorption plate, and sterilization layer before spraying it onto the user. Pesticides, dust, and impurities in the airflow are adsorbed and blocked by the activated carbon adsorption plate, and the sterilization layer disinfects the airflow, keeping the air the user breathes clean and thus protecting their health. The rotating movable box also raises and lowers the duct, ensuring that the airflow from the duct covers the user's entire body, preventing pesticides from adhering to the user's skin and clothing and causing harm.

[0010] Simultaneously, the fan draws outside air through the duct, fan, and dust collection pipe, then ejects it from the dust collection port. This airflow assists the cleaning brush in cleaning dust from the photovoltaic panels and also dissipates heat from the photovoltaic panels and rotating motor, thereby improving the power generation efficiency of the photovoltaic panels. This airflow also cleans the cleaning brush, increasing its cleaning efficiency on the photovoltaic panels. Furthermore, this airflow ejects dust and impurities blocked by the activated carbon adsorption plate from the dust collection port, preventing the duct from becoming clogged.

[0011] Furthermore, the two nozzles are oriented in opposite directions.

[0012] The two nozzles are oriented in opposite directions, allowing the farmland on both sides of the sprayer to be sprayed simultaneously, thus improving the spraying efficiency of the sprayer.

[0013] Furthermore, the photovoltaic panel is semi-circular and is positioned above the water storage tank and two nozzles, with its two side edges fixedly connected to the movable box.

[0014] The photovoltaic panels can block the upward spray of pesticides from the two nozzles, collecting the pesticides into a movable box. Simultaneously, the upward-spraying pesticides also cool the photovoltaic panels, improving their power generation efficiency. By using semi-circular photovoltaic panels, the pesticides sprayed from the two nozzles are also directed to the sides of the sprayer, thus protecting the user.

[0015] Furthermore, the system includes a collection tank, a collection pipe, a delivery pipe, and a second water pump. The collection tank is located on the side of the movable box away from the baffle and is fixedly connected to the base. One end of the delivery pipe is connected to the collection tank, and the other end is connected to the side of the movable box near the collection tank. The second water pump is located inside the collection tank and is electrically connected to the controller. One end of the delivery pipe is connected to the water inlet of the second water pump, and the other end is connected to the water storage tank.

[0016] The collection bucket collects pesticides from the active box through a collection pipe. When it is necessary to recycle the pesticides in the collection bucket, the user controls the second water pump to start through the controller. The second water pump transports the pesticides in the collection bucket to the storage tank through the delivery pipe.

[0017] Furthermore, the baffle is arc-shaped, and the center of its arc coincides with the rotation axis of the movable box.

[0018] The airflow ejected from the dust removal port is guided by the baffle to clean the photovoltaic panels and cleaning brushes, and then the airflow is directed away from the user to prevent dust and impurities in the airflow from affecting the user's health.

[0019] Furthermore, the two nozzles and the water tank are positioned close to the collection tank.

[0020] When the sprayer is not in use, the movable box tilts towards the collection bucket under the gravity of the water storage bucket, preventing the photovoltaic panel from tilting towards the baffle and being blocked by the baffle, making the photovoltaic panel fully exposed, thereby improving the power generation efficiency of the photovoltaic panel.

[0021] Furthermore, the sterilization layer is made of nano silver ion coating.

[0022] Using nano silver ion coating can disinfect the air flow.

[0023] Furthermore, it includes a number of turbulence protrusions, which are fixed on the inner wall of the air duct.

[0024] By disturbing the air flow in the air duct through the turbulence protrusions, the contact range between the air flow in the air duct and the sterilization layer can be increased, thereby improving the disinfection effect on the air flow.

[0025] A working method of an agricultural sprayer with a solar photovoltaic structure. When pesticides need to be sprayed, the user controls the driving motor to rotate at a speed T through the controller. The driving motor drives the rotating disk to rotate self - clockwise. The rotating disk drives the pushing rod to rotate. The pushing rod pushes the movable box to rotate. The movable box drives the water storage bucket, the spray pipe, and the two nozzles to rise. When the rotating disk drives the pushing rod to rotate half a circle, the pushing rod will push the movable box to rotate in the opposite direction, and the movable box drives the water storage bucket, the spray pipe, and the two nozzles to descend, so that the two nozzles rise and fall periodically.

[0026] The rotating movable box will drive the air duct to rise and fall, so that the air flow ejected from the air duct can protect the entire body of the user.

[0027] A working method of an agricultural sprayer with a solar photovoltaic structure. When the user needs to focus on respiratory protection, the user controls the driving motor to rotate at a speed W through the controller. The driving motor drives the rotating disk to rotate self - clockwise. The rotating disk drives the pushing rod to rotate. The pushing rod pushes the movable box to rotate. The movable box drives the water storage bucket, the spray pipe, and the two nozzles to rise. Then the movable box descends under the gravity of the water storage bucket, the spray pipe, and the two nozzles, so that the two nozzles rise and fall periodically.

[0028] Where W < T, so that the movable box can always tilt towards the collection bucket, making the air flow ejected from the air duct concentrate on the user's head, and being able to focus on protecting the user's respiration.

[0029] The beneficial effects of the present invention:

[0030] 1. In this invention, the drive motor rotates the rotating disk, which in turn rotates the push rod. The push rod then rotates the movable box, which in turn moves the water tank, spray pipe, and two nozzles upwards. After the rotating disk rotates the push rod half a turn, the push rod then moves the movable box in the opposite direction. The movable box then moves the water tank, spray pipe, and two nozzles downwards, causing the two nozzles to periodically rise and fall, thus periodically changing the spray height and making the spraying more uniform. Simultaneously, the rotating motor drives the rotating rod to reciprocate, which in turn drives the water tank, spray pipe, and two nozzles to reciprocate, causing the spray angle of the two nozzles to change periodically, further enhancing the uniformity of the spray. This periodic change in the spray angle and height of the sprayer results in a more uniform spray.

[0031] 2. In this invention, a fan draws outside air through a duct, the fan itself, an activated carbon adsorption plate, and a sterilization layer before spraying it onto the user. Pesticides, dust, and impurities in the airflow are adsorbed and blocked by the activated carbon adsorption plate, and the sterilization layer disinfects the airflow, keeping the air the user breathes clean and thus protecting their health. The rotating movable box also raises and lowers the duct, ensuring that the airflow from the duct covers the user's entire body, preventing pesticides from adhering to the user's skin and clothing and causing harm.

[0032] 3. In this invention, the fan draws outside air through the duct, the fan, and the dust collection pipe, and then ejects it from the dust collection port. This airflow assists the cleaning brush in cleaning dust from the photovoltaic panel and also dissipates heat from the photovoltaic panel and the rotating motor, thereby improving the power generation efficiency of the photovoltaic panel. This airflow also cleans the cleaning brush, improving its cleaning efficiency on the photovoltaic panel. Furthermore, this airflow ejects dust and impurities blocked by the activated carbon adsorption plate from the dust collection port, preventing the duct from becoming clogged.

[0035] The following will describe the concept and technical effects of the present invention clearly and completely with reference to the embodiments, so as to fully understand the purpose, features and effects of the present invention.

[0036] As shown in Figure 1, an agricultural sprayer with a solar photovoltaic structure includes a base 1, two support rods, a movable box 3, a rotating rod 32, a water storage tank 35, a first water pump, a spray pipe, two nozzles 34, a drive motor 2, a rotating disk 21, a push rod 22, a controller, four moving wheels 11, a push handle 12, a rotating motor 31, an air duct 5, a fan 52, an activated carbon adsorption plate 53, a sterilization layer, a photovoltaic panel 33, a baffle 4, a cleaning brush 41, a sliding port, a battery, a dust removal pipe 51, and a dust removal port. The base 1 is horizontally positioned. The push handle 12 is positioned above the base 1 and fixedly connected to it. The two support rods are vertically positioned above the base 1, with their lower ends fixedly connected to the top of the base 1. The movable box 3 is inclinedly positioned above the base 1, between the two support rods, and to the side of the push handle 12. The two sides of the movable box 3 are rotatably connected to the upper ends of the two support rods, and the rotation axis of the movable box 3 is horizontally positioned and perpendicular to the inclination direction of the movable box 3. A rotating rod 32 is disposed inside the movable box 3, along the inclined direction of the movable box 3. Both ends of the rotating rod 32 are rotatably connected to the inner wall of the movable box 3, and its rotation axis coincides with the axis of the rotating rod 32. A rotating motor 31 is a forward and reverse rotating motor, disposed on the side of the movable box 3 near the push handle 12, and fixedly connected to the movable box 3. The rotating shaft of the rotating motor 31 passes through the movable box 3 and is fixedly connected to one end of the rotating rod 32. A water storage tank 35 is disposed inside the movable box 3 and fixedly connected to the rotating rod 32. A first water pump is disposed inside the water storage tank 35 and fixedly connected to the water storage tank 35. A spray pipe is a rigid pipe, one end connected to the water inlet of the first water pump, and the other end extending out of the water storage tank 35. The spray pipe is fixedly connected to the water storage tank 35. Two nozzles 34 are fixedly connected to the end of the spray pipe outside the water storage tank 35, and the orientation of the two nozzles 34 is along the rotation axis of the movable box 3. A drive motor 2 is positioned above the base 1 and below the movable box 3. The drive motor 2 is fixedly connected to the base 1, and its shaft axis is vertically oriented, intersecting the rotation axis of the movable box 3. A rotating disk 21 is horizontally positioned above the motor and below the movable box 3. The axis of the rotating disk 21 coincides with the shaft axis of the drive motor 2, and the center of the rotating disk 21 is fixedly connected to the shaft of the drive motor 2. A push rod 22 is vertically positioned above the rotating disk 21 and below the movable box 3. The push rod 22 is located to the side of the rotation axis of the rotating disk 21, with its lower end fixedly connected to the rotating disk 21 and its upper end in contact with the movable box 3. The upper end of the push rod 22 is spherical. Four moving wheels 11 are positioned below the base 1 and fixedly connected to it. The moving direction of the four moving wheels 11 is perpendicular to the rotation axis of the movable box 3. The duct 5 is a straight pipe, located on the side of the movable box 3 near the push handle 12, below the rotating motor 31. The axis of the duct 5 is set along the inclined direction of the movable box 3, and the duct 5 is fixedly connected to the movable box 3. The fan 52 is installed inside the duct 5 and is fixedly connected to the duct 5.An activated carbon adsorption plate 53 is disposed inside the air duct 5, located on the side of the fan 52 away from the movable box 3, and is fixedly connected to the air duct 5. A sterilization layer is disposed on the inner wall of the air duct 5, on the side of the activated carbon adsorption plate 53 away from the movable box 3. A photovoltaic panel 33 is arc-shaped, disposed above the movable box 3, and fixedly connected to the movable box 3, with the center of the arc of the photovoltaic panel 33 coinciding with the rotation axis of the movable box 3. A baffle 4 is disposed above the base 1, between the movable box 3 and the push handle 12, and is fixedly connected to the base 1. A cleaning brush 41 is disposed on the side of the baffle 4 near the movable box 3, fixedly connected to the baffle 4, and in contact with the surface of the photovoltaic panel 33. A sliding port is disposed on the baffle 4 and fitted onto the air duct 5, the sliding port being adapted to the movement path of the air duct 5. The dust removal pipe 51 is horizontally positioned between the movable box 3 and the baffle 4, above the air duct 5. The dust removal pipe 51 is parallel to the rotation axis of the movable box 3, fixed to and connected to the middle of the air duct 5. The connection point between the dust removal pipe 51 and the air duct 5 is located between the fan 52 and the activated carbon adsorption plate 53. The dust removal port is strip-shaped, parallel to the rotation axis of the movable box 3, and positioned at the top of the dust removal pipe 51, connecting to it. The battery is located at the top of the base 1 and electrically connected to the photovoltaic panel 33. The controller is electrically connected to the drive motor 2, the first water pump, the rotating motor 31, the fan 52, and the battery.

[0037] When pesticide spraying is needed, the user moves the sprayer by pushing the handle 12. Simultaneously, the user controls the first water pump, blower 52, drive motor 2, and rotary motor 31 to start via the controller. The first water pump sprays the pesticide from the storage tank 35 through the spray pipe and two nozzles 34 onto the farmland to the side of the sprayer. At the same time, the drive motor 2 drives the rotating disc 21 to rotate, which in turn drives the push rod 22 to rotate. The push rod 22 then drives the movable box 3 to rotate, causing the storage tank 35, spray pipe, and two nozzles 34 to rise. After the rotating disc 21 drives the push rod 22 to rotate half a turn, the push rod 22 will then drive the movable box 3 to rotate in the opposite direction. The movable box 3 then causes the storage tank 35, spray pipe, and two nozzles 34 to descend, thus causing the two nozzles 34 to periodically rise and fall, periodically changing the spraying height, resulting in more even spraying. Simultaneously, the rotating motor 31 drives the rotating rod 32 to rotate reciprocally. The rotating rod 32 drives the water storage tank 35, the spray pipe, and the two nozzles 34 to rotate reciprocally, thereby causing the spraying angle of the two nozzles 34 to change periodically, thus making the spraying of the sprayer more uniform. This periodic change in the spraying angle and spraying height of the sprayer further enhances the uniformity of the spraying.

[0038] The photovoltaic panel 33 stores the generated electricity in a battery. The rotating movable box 3 drives the photovoltaic panel 33 to rotate back and forth, and the cleaning brush 41 cleans the dust on the surface of the photovoltaic panel 33, thereby improving the power generation efficiency of the photovoltaic panel 33.

[0039] Simultaneously, the fan 52 draws outside air through the duct 5, the fan 52, the activated carbon adsorption plate 53, and the sterilization layer before spraying it onto the user. Pesticides, dust, and impurities in the airflow are adsorbed and blocked by the activated carbon adsorption plate 53, and the sterilization layer disinfects the airflow, keeping the air the user breathes clean and thus protecting their health. The rotating movable box 3 also raises and lowers the duct 5, ensuring that the airflow from the duct 5 covers the user's entire body, preventing pesticides from adhering to the user's skin and clothing and causing harm.

[0040] Simultaneously, the fan 52 draws outside air through the duct 5, the fan 52, and the dust removal pipe 51, and ejects it from the dust removal port. This airflow assists the cleaning brush 41 in cleaning dust from the photovoltaic panel 33 and also dissipates heat from the photovoltaic panel 33 and the rotating motor 31, thereby improving the power generation efficiency of the photovoltaic panel 33. This airflow also cleans the cleaning brush 41, improving its cleaning efficiency on the photovoltaic panel 33. Furthermore, this airflow ejects dust and impurities blocked by the activated carbon adsorption plate 53 from the dust removal port, preventing the duct 5 from becoming clogged.

[0041] The two nozzles 34 are oriented in opposite directions.

[0042] The two nozzles 34 are oriented in opposite directions, which allows the farmland on both sides of the sprayer to be sprayed simultaneously, thus improving the spraying efficiency of the sprayer.

[0043] The photovoltaic panel 33 is semi-circular and is positioned above the water storage tank 35 and two nozzles 34, with its two sides fixedly connected to the movable box 3.

[0044] The photovoltaic panel 33 can block the pesticide sprayed upwards from the two nozzles 34, thereby collecting the upward-sprayed pesticide into the movable box 3. At the same time, the upward-sprayed pesticide can also cool the photovoltaic panel 33, improving its power generation efficiency. By setting the photovoltaic panel 33 in a semi-circular arc shape, the pesticide sprayed from the two nozzles 34 can also be directed to the sides of the sprayer, thus protecting the user.

[0045] The system includes a collection tank 6, a collection pipe 63, a delivery pipe 61, and a second water pump 62. The collection tank 6 is located on the side of the movable box 3 away from the baffle 4 and is fixedly connected to the base 1. One end of the delivery pipe 61 is connected to the collection tank 6, and the other end is connected to the side of the movable box 3 near the collection tank 6. The second water pump 62 is located inside the collection tank 6 and is electrically connected to the controller. One end of the delivery pipe 61 is connected to the water inlet of the second water pump 62, and the other end is connected to the water storage tank 35.

[0046] The collection bucket 6 collects the pesticides in the active box 3 through the collection pipe 63. When it is necessary to recycle the pesticides in the collection bucket 6, the user controls the second water pump 62 to start through the controller. The second water pump 62 transports the pesticides in the collection bucket 6 to the water storage bucket 35 through the delivery pipe 61.

[0047] The baffle 4 is arc-shaped, and the center of its arc coincides with the rotation axis of the movable box 3.

[0048] The airflow ejected from the dust removal port is guided by the baffle 4 to clean the photovoltaic panel 33 and the cleaning brush 41, and then is guided away from the user by the baffle 4, thereby preventing dust and impurities in the airflow from affecting the user's health.

[0049] Two nozzles 34 and a water storage tank 35 are positioned close to the collection tank 6.

[0050] When the sprayer is not in use, the movable box 3 tilts towards the collection bucket 6 under the gravity of the water storage tank 35, preventing the photovoltaic panel 33 from tilting towards the baffle 4 and being blocked by the baffle 4, so that the photovoltaic panel 33 is fully exposed, thereby improving the power generation efficiency of the photovoltaic panel 33.

[0051] The sterilization layer uses a nano silver ion coating.

[0052] Nano-silver ion coatings can be used to disinfect airflow.

[0053] This includes any turbulent flow protrusions, which are fixed to the inner wall of the duct 5.

[0054] By agitating the airflow within the duct 5 through the turbulence protrusions, the contact range between the airflow and the sterilization layer within the duct 5 can be increased, thereby enhancing the disinfection effect of the airflow.

[0055] Work process:

[0056] When pesticide spraying is needed, the user moves the sprayer by pushing the handle 12. Simultaneously, the user controls the first water pump, blower 52, drive motor 2, and rotary motor 31 to start via the controller. The first water pump sprays the pesticide from the water tank 35 through the spray pipe and two nozzles 34 onto the farmland on both sides of the sprayer. At the same time, the drive motor 2 drives the rotating disc 21 to rotate, which in turn drives the push rod 22 to rotate. The push rod 22 then drives the movable box 3 to rotate, causing the water tank 35, spray pipe, and two nozzles 34 to rise. After the rotating disc 21 drives the push rod 22 to rotate half a turn, the push rod 22 will then drive the movable box 3 to rotate in the opposite direction. The movable box 3 then causes the water tank 35, spray pipe, and two nozzles 34 to descend, thus periodically raising and lowering the two nozzles 34, periodically changing the spraying height, thereby making the spraying more even. Simultaneously, the rotating motor 31 drives the rotating rod 32 to rotate reciprocally. The rotating rod 32 drives the water storage tank 35, the spray pipe, and the two nozzles 34 to rotate reciprocally, thereby causing the spraying angle of the two nozzles 34 to change periodically, thus making the spraying of the sprayer more uniform. This periodic change in the spraying angle and spraying height of the sprayer further enhances the uniformity of the spraying.

[0057] The photovoltaic panel 33 can block the pesticide sprayed upwards from the two nozzles 34, thereby collecting the upward-sprayed pesticide into the movable box 3. Simultaneously, the upward-spraying pesticide also cools the photovoltaic panel 33, improving its power generation efficiency. The photovoltaic panel 33 stores the generated electricity in a battery. The rotating movable box 3 drives the photovoltaic panel 33 to rotate reciprocally, and the cleaning brush 41 cleans the dust from the surface of the photovoltaic panel 33, further improving its power generation efficiency.

[0058] Simultaneously, the fan 52 draws outside air through the duct 5, the fan 52, the activated carbon adsorption plate 53, and the sterilization layer before spraying it onto the user. Pesticides, dust, and impurities in the airflow are adsorbed and blocked by the activated carbon adsorption plate 53, and the sterilization layer disinfects the airflow, keeping the air the user breathes clean and protecting their health. The rotating movable box 3 also raises and lowers the duct 5, ensuring that the airflow from the duct 5 covers the user's entire body, preventing pesticides from adhering to the user's skin and clothing and causing harm. The turbulence protrusions agitate the airflow within the duct 5, increasing the contact area between the airflow and the sterilization layer, thereby enhancing the disinfection effect.

[0059] Simultaneously, the fan 52 draws outside air through the duct 5, the fan 52, and the dust removal pipe 51, and ejects it from the dust removal port. Guided by the baffle 4, the airflow from the dust removal port cleans the photovoltaic panel 33 and the cleaning brush 41, then is directed away from the user by the baffle 4, thus preventing dust and impurities in the airflow from affecting the user's health, thereby improving the power generation efficiency of the photovoltaic panel 33 and the cleaning efficiency of the cleaning brush 41 on the photovoltaic panel 33. This airflow can also eject dust and impurities blocked by the activated carbon adsorption plate 53 from the dust removal port, thus preventing the duct 5 from becoming clogged.

[0060] The collection bucket 6 collects the pesticides in the active box 3 through the collection pipe 63. When it is necessary to recycle the pesticides in the collection bucket 6, the user controls the second water pump 62 to start through the controller. The second water pump 62 transports the pesticides in the collection bucket 6 to the water storage bucket 35 through the delivery pipe 61.

[0061] When the sprayer is not in use, the movable box 3 tilts towards the collection bucket 6 under the gravity of the water storage tank 35, preventing the photovoltaic panel 33 from tilting towards the baffle 4 and being blocked by the baffle 4, so that the photovoltaic panel 33 is fully exposed, thereby improving the power generation efficiency of the photovoltaic panel 33.

[0062] A method for operating an agricultural sprayer with a solar photovoltaic structure: When pesticide spraying is required, the user controls the drive motor 2 to rotate at a speed T via a controller. The drive motor 2 drives the rotating disk 21 to rotate, which in turn drives the push rod 22 to rotate. The push rod 22 then drives the movable box 3 to rotate, causing the water tank 35, spray pipe, and two nozzles 34 to rise. After the rotating disk 21 drives the push rod 22 to rotate half a turn, the push rod 22 will drive the movable box 3 to rotate in the opposite direction. The movable box 3 then drives the water tank 35, spray pipe, and two nozzles 34 to descend, thus causing the two nozzles 34 to rise and fall periodically.

[0063] The rotating movable box 3 will cause the air duct 5 to rise and fall, so that the airflow sprayed from the air duct 5 will protect the user's entire body.

[0064] A method for operating an agricultural sprayer with a solar photovoltaic structure: When the user needs to focus on respiratory protection, the user controls the drive motor 2 to rotate at a speed W via the controller. The drive motor 2 drives the rotating disk 21 to rotate, the rotating disk 21 drives the push rod 22 to rotate, the push rod 22 drives the movable box 3 to rotate, the movable box 3 drives the water storage tank 35, the spray pipe, and the two nozzles 34 to rise, and then the movable box 3 descends under the gravity of the water storage tank 35, the spray pipe, and the two nozzles 34, thereby causing the two nozzles 34 to rise and fall periodically.

[0065] Where W < T, at this time, the thrust of the push rod 22 on the movable box 3 is not sufficient to cause the movable box 3 to rotate greatly, so that the movable box 3 can always tilt towards the collection bucket 6, making the airflow ejected from the air duct 5 concentrate on the user's head, and being able to centrally protect the user's breathing.

[0066] The above embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative efforts all fall within the scope of protection of the present invention.
