DETAILED DESCRIPTION

[0023] See also Figure 1-5The utility model provides an automatic crop spraying drone, including a drone body 1, a water tank 2 is fixed to the surface of the bottom of the drone body 1, a motor 3 is fixed to the surface of one side of the top of the water tank 2, a connecting shaft 4 is fixed to the output end of the motor 3, a first gear 5 is fixedly sleeved on the outer circumferential surface of the connecting shaft 4, a toothed disc 6 is meshed on one side of the first gear 5, a sleeve frame 7 is provided at the bottom of the toothed disc 6, a resistance rod 8 is inserted inside the sleeve frame 7, the top of the resistance rod 8 is fixed to the surface of the bottom of the toothed disc 6, two connecting strips 16 are fixed to the surface of one side of the sleeve frame 7, a fixing block 9 is fixed to a position on one side of the connecting strip 16 on the bottom surface of the water tank 2, a spray head 10 is provided at a middle position of the two fixing blocks 9, a water outlet pipe 11 is connected and fixed to the bottom surface of the water tank 2 at a middle position of the two connecting strips 16, a rubber hose 12 is connected and fixed to the bottom of the water outlet pipe 11, and the bottom of the rubber hose 12 is connected and fixed to the spray head The top of 10 is connected and fixed, and a rotating shaft 13 is fixed on the surface of both ends of the spray head 10. One end of the rotating shaft 13 is rotatably connected to the outer circumference of the adjacent fixed block 9. The outer circumference of the rotating shaft 13 is fixedly sleeved with a second gear 14. The top of the second gear 14 is meshed with a rack 15. One side of the rack 15 is fixed to the surface of the adjacent connecting strip 16. By starting the motor 3, the connecting strip 16 can drive the rack 15 to reciprocate in the horizontal direction, so that the spray head 10 can swing back and forth at a certain angle, so that the range of pesticide spraying can be expanded during the flight of the drone body 1 to spray pesticides, thereby ensuring the uniformity of pesticide spraying. The pesticide inside the water tank 2 can be guided to the inside of the spray head 10 through the water outlet pipe 11. The setting of the rubber hose 12 can facilitate the spray head 10 to swing when the spray head 10 is at the water outlet pipe 11.

[0024] Further as Figure 1 , Figure 4 and Figure 5 As shown, it is worth explaining in detail that a support groove 17 with a T-shaped cross-section is provided on the outer peripheral surface of the bottom surface of the water storage tank 2 located at the top of the toothed disc 6, and a support ring 18 with a T-shaped cross-section is inserted into the support groove 17. The bottom of the support ring 18 is fixed to the surface of the top of the toothed disc 6. Since the support ring 18 is supported and limited by the support groove 17, it can support the toothed disc 6 while making its movement state during rotation more stable.

[0025] Further as Figure 4 As shown, it is worth explaining in detail that the diameter of the bottom of the outer circumference of the resistance rod 8 is larger than the top of the outer circumference, and the surface of the bottom of the outer circumference of the resistance rod 8 fits with the surface of the bottom of the sleeve frame 7. Through the shape setting of the resistance rod 8, the resistance rod 8 can support the sleeve frame 7, so that the state of the sleeve frame 7 during the reciprocating motion is more stable.

[0026] Further as Figure 4 As shown, it is worth explaining in detail that the water tank 2 is internally rotatably connected with three rotating shafts 19, and a plurality of stirring rods 21 are evenly fixed at the upper and lower ends of the outer circumference of the rotating shaft 19. A third gear 22 is fixedly sleeved at a position on the outer circumference of the rotating shaft 19 close to one side of the inner wall of the water tank 2, and the third gears 22 at two adjacent positions are meshingly connected. One side of the outer circumference of one rotating shaft 19 passes through the water tank 2 and extends to the outside of the water tank 2, and a fan blade 20 is fixedly sleeved at a position where the outer circumference of one rotating shaft 19 extends out of the outer part of the water tank 2. When the drone body 1 is flying, the fan blade 20 will be blown by the wind to drive the ventilation rotating shaft 19 to rotate, thereby driving one of the third gears 22 to rotate, so that the meshing action between the third gears 22 at adjacent positions enables multiple rotating shafts 19 to drive the third gear 22 to make a circular motion, thereby stirring the pesticide entering the water tank 2.

[0027] This solution has the following working process: in actual use, when the user operates the drone body 1 to spray pesticides, the fan blades 20 of the drone body 1 will be blown by the wind during the flight of the drone body 1, so that it drives the ventilation rotating shaft 19 to rotate, thereby driving one of the third gears 22 to rotate, so that the meshing action between the third gears 22 at adjacent positions can make multiple rotating shafts 19 drive the third gears 22 to make circular motion, so that the pesticide entering the water tank 2 can be stirred, so as to prevent the pesticide from precipitating inside the water tank 2 and affecting its use effect, and then by starting the motor 3 and the spray head 10, the connecting shaft 4 is rotated, so that the first gear 5 is rotated, so that the toothed disc 6 can be rotated under the meshing action between the first gear 5 and the toothed disc 6 and the supporting and limiting action of the support groove 17 and the support ring 18 on the toothed disc 6, so that the toothed disc 6 can drive the contact rod 8 to make a circular motion, so that the sleeve frame 7 can make a reciprocating motion in the horizontal direction under the contact support state of the contact rod 8 and the sleeve frame 7, so that the connecting bar 16 can drive the two racks 15 to make a reciprocating motion in the horizontal direction, so that the meshing action between the rack 15 and the second gear 14 can make the rotating shaft 13 drive the second gear 14 to reciprocate along a certain angle, so that the range of pesticide spraying by the spray head 10 when the drone body 1 is flying can be expanded, thereby ensuring the uniformity of pesticide spraying.

[0028] According to the above working process, it can be known that by starting the motor 3, the connecting bar 16 can drive the rack 15 to reciprocate in the horizontal direction, so that the spray head 10 can reciprocate along a certain angle, so that the range of pesticide spraying can be expanded during the flight of the drone body 1 to spray pesticides, thereby ensuring the uniformity of pesticide spraying, thereby improving the practicality of the device, and by rotating one of the rotating shafts 19 under the action of wind when the drone body 1 is flying, so that the multiple rotating shafts 19 can rotate synchronously under the meshing action of multiple third gears 22, so that the pesticide liquid entering the water tank 2 is stirred through the motion trajectory of the stirring rod 21, thereby preventing the pesticide from precipitating inside the water tank 2 to reduce its use effect, thereby further improving the practicality of the device.

[0029] Further as Figure 4 As shown, it is worth explaining in detail that the stirring rod 21 is arranged at an angle, and two groups of stirring rods 21 are placed at the upper and lower ends of the outer circumference of the rotating shaft 19 with the center line of the horizontal direction of the front side of the rotating shaft 19 as the symmetry axis. Due to the shape of the stirring rod 21, the stirring rod 21 can stir a wider range of liquids, and due to the position of the stirring rod 21, the stirring range of the pesticide inside the water tank 2 is more uniform.

[0030] In summary: by starting the motor 3, the connecting bar 16 can drive the rack 15 to reciprocate in the horizontal direction, so that the spray head 10 can swing back and forth at a certain angle, so that the range of pesticide spraying can be expanded during the flight of the drone body 1 to spray pesticides, thereby ensuring the uniformity of pesticide spraying, thereby improving the practicality of the device, by causing one of the rotating shafts 19 to rotate under the action of wind when the drone body 1 is flying, so that the multiple rotating shafts 19 can rotate synchronously under the meshing action of multiple third gears 22, so that the pesticide liquid entering the water tank 2 is stirred through the movement trajectory of the stirring rod 21, thereby preventing the pesticide from precipitating inside the water tank 2 and reducing its use effect, thereby further improving the practicality of the device, due to the shape setting of the stirring rod 21, the stirring rod 21 can stir a wider range of liquid, and due to the position setting of the stirring rod 21, the stirring range of the pesticide inside the water tank 2 is made more uniform.

[0031] The motor 3 and the spray head 10 can be purchased on the market. The motor 3 and the spray head 10 are equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so it is not repeated in the specification.
