Description

Technical Field

[0001] The invention relates to the field of unmanned aerial vehicles (UAVs), in particular to an agricultural pesticide spraying UAV. Background Art

[0002] Pesticide spraying drones are composed of three parts: a flight platform (fixed-wing, helicopter, multi-axis aircraft), a navigation flight control, and a spraying mechanism. Spraying operations are achieved through ground remote control or navigation flight control. Agricultural drones are not only used for spraying pesticides, but also for spreading fertilizers, seeds, feed, and other tasks to meet the diverse needs of farmers and improve production efficiency.

[0003] The Chinese patent discloses an agricultural pesticide spraying drone (Announcement No. CN112660388B), which includes a drone body, a flight structure, a shock-absorbing structure, a mounting structure, a pressurizing structure, a spraying structure and a fixing structure. By installing the shock-absorbing structure at the bottom of the drone body, it is not only convenient for the drone body to move on land, but also enables the drone body to play a sufficient buffering role when landing, avoiding the drone body from directly landing on the ground and causing damage to the drone body. While the flight structure is working, it can also drive the pressurizing structure to work synchronously. Through the pressurizing work of the pressurizing structure, the stored pesticide liquid storage tank can be pressurized, so that the pesticide can be sprayed in a mist form, so as to spray the crops more comprehensively. The spraying work only starts when the drone body is flying, and the waste of pesticide can be avoided.

[0004] When the above-mentioned existing pesticide spraying drone atomizes the pesticide and sprays it out, the airflow in the air will blow the atomized medicine to a certain direction, causing the atomized medicine to be carried away by the airflow.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figures 1 to 8 In an embodiment of the present invention, an agricultural pesticide spraying drone includes a spraying drone 1, a mounting frame 101 is fixedly installed at the lower end of the propeller bracket of the spraying drone 1, and a spraying mechanism 2 that can automatically adjust the angle and direction of spraying medicine is arranged at the lower end of the mounting frame 101. The spraying mechanism 2 can prevent the spraying drone 1 from being affected by airflow in the air. The spraying mechanism 2 can change the spraying angle according to the direction of the airflow, so that the medicine can be sprayed stably during the spraying process. The spraying mechanism 2 includes a nozzle 201, and a water storage tank 202 loaded with medicine is fixedly installed at the lower end of the spraying drone 1, and an output pump 203 is fixedly installed at the upper end of the water storage tank 202. The output end of the output pump 203 is fixedly installed with a feed pipe 2 04, and the nozzle 201 is arranged at one end of the material transfer pipe 204 away from the output pump 203. When it is necessary to spray the medicine, start the output pump 203, so that the output pump 203 transfers the medicine in the water tank 202 to the nozzle 201 through the material transfer pipe 204 for spraying. The upper end of the spraying drone 1 is provided with a wind direction mechanism 3 for controlling the tilt direction of the nozzle 201. When the airflow in the air blows the wind direction mechanism 3, the wind direction mechanism 3 starts to drive the nozzle 201 to rotate to the direction of the airflow, so that the nozzle 201 can change the spraying angle of the nozzle 201 under the action of the airflow. The wind direction mechanism 3 is provided with a wind power mechanism 4 for controlling the tilt angle of the nozzle 201. The wind power mechanism 4 can make it more convenient to control the tilt angle of the nozzle 201.

The protective cover 102, the protective tube 103 and the protective tube 104 installed on the mounting frame 101 can protect the mechanism for adjusting the nozzle 201 in the wind direction mechanism 3 and the wind force mechanism 4. A connecting ring 205 is rotatably installed at one end of the material transfer pipe 204 away from the output pump 203, and a connecting pipe 206 is fixedly installed at the lower end of the connecting ring 205 The lower end of the connecting pipe 206 is fixedly connected with a foldable and retractable telescopic hose 207, and the lower end of the telescopic hose 207 is fixedly connected with a universal ball 208, and the nozzle 201 is fixedly installed at the lower end of the universal ball 208, and a water hole is provided in the universal ball 208, and the telescopic hose 207 is fixedly installed at the upper end of the water hole. When the angle of the nozzle 201 needs to be adjusted, the universal ball 208 drives the nozzle 201 to rotate, so that the telescopic hose 207 bends and stretches, thereby preventing the universal ball 208 from pulling the pipeline and causing damage during the rotation process.

[0030] See also Figures 1 to 5 The wind direction mechanism 3 includes an installation box 301, and the installation box 301 is fixedly installed on the upper end of the spraying drone 1, and a fixing box 302 is fixedly installed on the lower end of the installation box 301. A turntable 303 is rotatably installed on the upper end of the installation box 301, and a driving gear 304 is fixedly installed on the lower end of the turntable 303. The side end of the driving gear 304 is meshed and connected with a transmission gear 305, and the diameter of the transmission gear 305 is twice the diameter of the driving gear 304. A winding drum 306 is fixedly installed on the lower end of the transmission gear 305, and the diameter of the transmission gear 305 is twice the diameter of the winding drum 306. The diameter ratio of the wheel 305 and the winding drum 306 makes it easier and more convenient to rotate the turntable 303. A transmission belt 307 is wound on the outer wall of the winding drum 306. Both ends of the transmission belt 307 away from the winding drum 306 are wound and connected to a rotating drum 308. A rotating rod 309 is fixedly installed on the inner wall of the rotating drum 308, and the rotating rod 309 is rotatably installed on the inner wall of the fixed box 302. A rotating gear 310 is fixedly installed on the lower end of the rotating rod 309. When the transmission belt 307 starts to move, it drives the rotating drum 308 to start rotating, so that the rotating rod 309 drives the rotating gear 310 to start rotating.

[0031] See also Figures 3 to 8, the rotating gear 310 is meshed and connected with a driven gear rod 311, and the driven gear rod 311 is meshed and symmetrically installed with multiple gear rods. When one of the driven gear rods 311 rotates, the driven gear rods 311 meshed on both sides rotate in the opposite direction. The end of the driven gear rod 311 away from the transmission gear 305 is fixedly installed with a connecting gear set 312, and the connecting gear set 312 is set as a gear set of a transmission. The above-mentioned connecting gear set 312 is a prior art and will not be described in detail here. When the driven gear rod 311 rotates, the connecting gear set 312 increases the torque of the driven gear rod 311 to rotate, and the end of the connecting gear set 312 away from the driven gear rod 311 is fixedly installed with a driven rod 313, and the end of the driven rod 313 away from the connecting gear set 312 is fixedly installed with a turbine gear 314, refer to Figure 4 and Figure 7 The tooth pattern of the turbine teeth 314 corresponding to the driven gear rods 311 symmetrically meshed on both sides of the driven gear rod 311 arranged in the middle is opposite to the tooth pattern direction of the turbine teeth 314 corresponding to the driven gear rod 311 arranged in the middle, and the side ends of the turbine teeth 314 are meshed and connected with the driven gear ring 315. When the rotating gear 310 drives the driven gear rod 311 in the middle to rotate, the driven gear rods 311 symmetrically arranged on both sides of the driven gear rod 311 in the middle rotate in the opposite direction. When the turbine teeth 314 corresponding to the driven gear rod 311 arranged in the middle rotate clockwise, the turbine teeth 314 corresponding to the symmetrical driven gear rods 311 rotate counterclockwise, so that the nozzle 201 arranged at the lower end of the mounting frame 101 on the spraying UAV 1 rotates in the same direction, and when the nozzle 201 is blown by the airflow, the driven gear ring 315 will not rotate, so that the nozzle 201 is more stable during the use and adjustment process.

[0032] See also Figures 7-8 A rotating drum 316 is fixedly installed at the lower end of the driven gear ring 315, and the rotation angle of the rotating drum 316 is the same as the rotation angle of the driving gear 304, and the rotating drum 316 rotates through the lower end of the protective cover 102, and a rotating frame 317 is fixedly installed at the lower end of the rotating drum 316, and the connecting ring 205 is rotatably installed on the upper end of the rotating frame 317, and the rotating frame 317 is rotatably installed on the inner wall of the protective cylinder 104, and the universal ball 208 is rotatably installed on the lower end of the rotating frame 317, and the side ends of the universal ball 208 are symmetrically provided with limit rods, so that the universal ball 208 can only rotate in one direction, thereby avoiding the nozzle 201 from tilting when adjusting the spraying direction of the nozzle 201.

[0033] See also Figures 3 to 6A mounting ring 318 is fixedly installed on the upper end of the turntable 303, and a gap is set in the mounting ring 318. A mounting cylinder 324 is rotatably installed in the gap of the mounting ring 318. A supporting telescopic rod 319 is fixedly installed on the upper end of the mounting cylinder 324, and a placement groove that matches the supporting telescopic rod 319 is set near the upper end of the mounting box 301 near the supporting telescopic rod 319, so that when the spraying drone 1 is not in use, it is more convenient to store the supporting telescopic rod 319, and the supporting telescopic rod 319 is prevented from colliding with other debris after storage. Causing damage, a fixed block 320 is fixedly installed on the upper end of the supporting telescopic rod 319, a sliding cylinder 321 is fixedly installed on the side end of the fixed block 320, a sliding block 322 is slidably installed on the inner wall of the sliding cylinder 321, and a spring telescopic rod is fixedly installed between the sliding block 322 and the sliding cylinder 321. The spring telescopic rod arranged between the sliding block 322 and the sliding cylinder 321 makes it easier for the sliding block 322 to return to its original position after moving, and a weather vane 323 is fixedly installed on the end of the sliding block 322 away from the sliding cylinder 321.

[0034] See also Figures 3 to 8The wind mechanism 4 includes a wind resistance plate 401, and the wind resistance plate 401 is symmetrically installed at the side end of the wind vane 323, so that when the wind vane 323 is blown by the airflow to be parallel to the airflow, the wind resistance plate 401 is perpendicular to the airflow, so that the airflow pushes the wind resistance plate 401, and the end of the sliding block 322 close to the sliding cylinder 321 is fixedly installed with a pulling rope 402, and the pulling rope 402 passes through the inside of the supporting telescopic rod 319. When the supporting telescopic rod 319 is retracted, the pulling rope 402 is folded and collected in the supporting telescopic rod 319, thereby avoiding The pull rope 402 falls into the fixed box 302, causing the gear to be damaged and stuck, and the fixed block 320 is rotated near the inner wall of the pull rope 402 and is installed with a guide rod, and the pull rope 402 is wound on the outer wall of the guide rod. The guide rod makes it easier to change the moving direction of the pull rope 402 when the pull rope 402 starts to move. The lower end of the pull rope 402 is fixedly installed with a brush block 403, and the inner wall of the brush block 403 is slidably installed with a resistance rod 404, and the resistance rod 404 is fixedly installed under the inner wall of the fixed box 302. The upper end of the resistance rod 404 is fixedly installed with a conducting wire 405, and the end of the conducting wire 405 away from the resistance rod 404 is fixedly installed with an electric telescopic rod 406. When the pull rope 402 pulls the brush block 403 to start moving upward, the brush block 403 moves upward, and the resistance in the conducting wire 405 decreases, and the voltage and current begin to increase, so that the input power of the electric telescopic rod 406 begins to increase, and the extension distance of the electric telescopic rod 406 begins to increase. The electric telescopic rod 406 is fixedly installed in the fixed box 302. On the inner wall of the fixed box 302, a piston ring 407 is fixedly installed on the output end of the electric telescopic rod 406, and a piston cylinder 408 is fixedly installed on the inner wall side end close to the piston ring 407, and the piston ring 407 is slidably installed on the inner wall of the piston cylinder 408. When the spraying drone 1 is in normal use, when the spraying drone 1 starts to move, the electric telescopic rod 406 will push the piston ring 407 to move a certain distance to avoid the airflow from having a certain impact on the wind vane 323 and the wind resistance plate 401 when the drone moves forward slowly normally.

[0035] See also Figures 3 to 8The output end of the piston cylinder 408 is fixedly installed with an output pipe 409, and the end of the output pipe 409 away from the piston cylinder 408 is fixedly installed with an air outlet plate 410, and the end of the air outlet plate 410 away from the output pipe 409 is fixedly installed with an air outlet pipe 411, and a plurality of air outlet pipes 411 are arranged in an array on the air outlet plate 410, and the air outlet pipes 411 are all arranged on the mounting frame 101 of the UAV, so that after the output pipe 409 transfers the air pressure of the piston cylinder 408 to the air outlet plate 410, the air outlet The air plate 410 evenly transfers the air pressure to the air outlet pipe 411. The end of the air outlet pipe 411 away from the air outlet plate 410 is rotatably connected to a connecting turret 412, and the connecting turret 412 is fixedly installed on the inner wall of the rotating frame 317. The side end of the connecting turret 412 is fixedly installed with an air inlet pipe 413. When the connecting turret 412 rotates the rotating frame 317, the gas in the air outlet pipe 411 can be continuously transferred to the air inlet pipe 413. The end of the air inlet pipe 413 away from the connecting turret 412 is fixedly installed. A pneumatic telescopic rod 414 is installed, and a push rod 415 is rotatably installed on the output end of the pneumatic telescopic rod 414, and the push rod 415 is fixedly installed on the side end of the universal ball 208. When the air pressure enters the pneumatic telescopic rod 414, the pneumatic telescopic rod 414 begins to extend, so that the pneumatic telescopic rod 414 pushes the push rod 415 to start rotating, so that the universal ball 208 drives the nozzle 201 to start rotating, so that it is more convenient to adjust the inclination angle of the nozzle 201. When the spraying drone 1 is just started, the electric telescopic rod 406 will push the piston ring 407 to move a certain distance, so that the pneumatic telescopic rod 414 will push the push rod 415 to rotate a certain distance under normal circumstances, so that the spraying drone 1 is slightly tilted to the front when it is flying forward slowly normally, so that when the smaller airflow blows the wind vane 323 to rotate, the airflow size cannot push the wind resistance plate 401 to move, and after the inclined nozzle 201 is rotated to be perpendicular to the airflow direction, the nozzle 201 can still play the role of spraying against the wind.

[0036] The working principle of the present invention is: when it is necessary to use the spraying drone 1 to spray the farmland, after adding the pesticide to be sprayed into the water tank 202, rotate the supporting telescopic rod 319, rotate the supporting telescopic rod 319 to be perpendicular to the installation box 301, extend the supporting telescopic rod 319, raise the wind vane 323 to a suitable height, start the spraying drone 1, fly the spraying drone 1 to the specified position, start the output pump 203, so that the pesticide in the water tank 202 is transferred to the connecting pipe 206 through the material transfer pipe 204, and then transferred to the nozzle 201 through the telescopic hose 207 and the universal ball 208, and sprayed through the nozzle 201, driving the spraying drone 1 to move forward slowly and uniformly, thereby spraying the farmland.

[0037] When there is wind in the air during the pesticide spraying process, the wind vane 323 rotates to be parallel to the airflow, and the supporting telescopic rod 319 drives the installation cylinder 324 to rotate, so that the installation ring 318 and the turntable 303 start to rotate, and the driving gear 304 starts to rotate a certain angle, so that the transmission gear 305 drives the winding cylinder 306 to start rotating, and the winding cylinder 306 rotates to pull the transmission belt 307 to move a certain distance, and the movement of the transmission belt 307 drives the rotating cylinder 308 to start rotating. The rotating rod 309 drives the rotating gear 310 to start rotating, and the rotating gear 310 drives the multiple driven gear rods 311 arranged in the array to start rotating, so that the connecting gear group 312 drives the driven rod 313 to start rotating, and the turbine teeth 314 with different thread directions arranged at one end of the driven rod 313 rotate, so that the driven gear ring 315 rotates in the same direction, and the rotating frame 317 starts to rotate. The nozzles 201 set on the spraying drone 1 are all rotated to be perpendicular to the windward direction, so that the spraying direction of the nozzles 201 is against the wind.

[0038] The wind resistance plate 401 provided on the wind vane 323 drives the sliding block 322 to start moving under the action of wind force, so that the pull rope 402 drives the brush block 403 to start moving upward, so that the resistance of the electric wire 405 is reduced, so that the power of the electric telescopic rod 406 is increased, so that the electric telescopic rod 406 pushes the piston ring 407 to move, and the air pressure in the piston cylinder 408 is transmitted to the air outlet plate 410 through the output pipe 409, and the air pressure enters the air outlet pipe 411 through the air outlet plate 410, and the air pressure The air is transmitted to the air inlet pipe 413 through the connecting rotating head 412, and then enters the pneumatic telescopic rod 414 through the air inlet pipe 413, so that the pneumatic telescopic rod 414 pushes the pushing rod 415, so that the universal ball 208 rotates to adjust the angle of the nozzle 201 when spraying perpendicular to the windward direction, so that the spraying drone 1 can automatically determine the wind direction and wind force when operating in windy weather, and thus automatically adjust the spraying direction and angle of the nozzle 201, so that the spraying drone 1 can spray farmland more accurately during use.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
