Description

Technical Field

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

[0002] The development of science and technology has also driven the innovation of agricultural technology. Due to the development of new agricultural technologies such as seed drills and harvesters, the cultivated area has changed from manual farming to mechanized farming, and the cultivated area has also been greatly expanded. Faced with the vast planting area, the way of spraying pesticides has also changed. Compared with crushing crops with a short distance, drones that can spray pesticides from the sky are gradually gaining recognition.

[0003] However, when drones are spraying, the solid-liquid mixture of pesticides needs to be stirred and sprayed. Existing drone stirring devices usually use traditional stirring rods for stirring. The unidirectional stirring will cause the powdered medicine inside the mixed liquid to flow along the direction of the water flow, which is easy to produce residue. In addition, the stirring device can only stir the water depth of a fixed length and cannot be adjusted in height to mobilize the powdered liquid that has settled to the bottom. When drones are spraying, they are easily affected by wind and cannot adjust the spraying intensity according to the wind strength.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In the present invention, through the linkage of the gear and the rotating rod structure, the stirring rod can move up and down while stirring, forming a cross stirring motion, thereby stirring the mixed liquid in the stirring drum in the vertical direction, and leading the powder residue settled on the bottom wall of the drum to above the water. At the same time, the spoilers located at multiple positions on the outside of the stirring rod can make the single rotating water flow undergo a certain degree of turbulent stirring, accelerate the mixing of solid and liquid, and improve the stirring efficiency.

[0019] In the present invention, through the wind vane on the top of the drone and the rotating shaft structure inside the wind vane, the diameter of the connecting pipe opening between the mixing drum and the discharge pipe can be adjusted when the wind force changes. As the wind force becomes stronger, the inner diameter of the pipe opening becomes smaller. While ensuring that the power of liquid medicine output is inconvenient, the narrower diameter can increase the power of liquid medicine discharge and simultaneously enhance the liquid medicine injection pressure of the spray head.

[0020] In the present invention, by setting up multiple spray heads, combining the wind vane on the top of the drone and the baffle structure at the bottom, when the wind is not strong, the spray heads hit the inner wall and pop out, expanding the spraying range and spreading the spray. As the wind increases, the holes in the middle of the baffle will gradually open, allowing the liquid medicine in the spray head to be concentrated on the same direction for spraying, thereby resisting the wind and avoiding the spraying effect of the scattered liquid medicine on the plants.

[0049] In summary, when using this agricultural plant protection spraying drone, first add water and medicine to the supply box 2 respectively, and then start the fan frame 11. As the drone frame 1 flies over the field, the controller 403 controls the water supply pump 402 to pour water into the mixing box 3, and the powder enters along the pipe on the top of the mixing box 3. Then the mixing motor 501 drives the motor rotating rod 502 to rotate, and the driving gear 503 on the side surface of the motor rotating rod 502 drives the driven gear 505 to rotate, and when it rotates, the driving gear 503 drives the driven gear 505 to rotate. The groove rod 506 and the hook rod 508 rotate to mix the powder and water. During the mixing process, the flow disturbance rod 509 disturbs the medicine and water in an opposite direction. The chaotic water flow makes the mixing efficiency of the medicine liquid higher. At the same time, the bevel gear rod 504 drives the bevel gear 5010 to rotate. The short winding plate 5011 rotates, pulling the connecting rod 5012 and the lower winding plate 5013 to rotate as well. The winding gear 5014 meshes and rotates the pulley rod 507, which moves up and down at the same time, causing the powder at the bottom of the mixing box 3 to surge up and down.

[0050] When the wind is not strong, the water pump in the mixing box 3 transports the liquid from the connecting water pipe 607 to the water pipe 1001, and then the liquid is discharged from the spray head 1003. The discharged liquid hits the hollow top plate 1005 and then floats along the top inner wall of the top cover 1004 in the field for range irrigation.

[0051] When the wind is strong, the wind blows the weather vane 803 and the top rod 802 to one side in the hollow frame 801. During the displacement, the lower winding rod 804 on the pressure side rotates on the bottom shaft seat 805. When the bottom shaft seat 805 deviates, the toothed plate 807 is driven to move up and down along the L-shaped sliding groove 808 through the cross-link plate 809. At this time, the central axis 8010 at the bottom middle of the cross-link plate 809 is displaced and squeezes the wheel seat 8012 to fall along the vertical frame 8011. When the wind is weak, the spring telescopic rod 8013 will push the central axis 8010 to return to its original position.

[0052] The toothed plate 807 that moves up and down drives the connected adjusting gear 708 and the upper rotating wheel 706 to rotate, and the driven bevel gear 703 and the meshing active bevel gear 702 are rotated synchronously through the belt 705, and the adjusting rod 701 drives the synchronous gear 601 to rotate. As long as the cross-link plate 809 deviates, the synchronous toothed plates 602 at the upper and lower ends of the synchronous gear 601 will converge inward, so that the two arc slot frames 605 move and close, reducing the diameter of the water outlet and increasing the water outlet pressure. Similarly, due to the side surface of the upper shaft rod 707 There is also an adjustment gear 708 at the other end of the surface, which will cause the multi-tooth slide 901 in the base 8014 to engage and move, wherein the racks on the side of the multi-tooth slide 901 engage to drive the upper rotating gear 902 and the lower rotating gear 904 to rotate, and the arc rack 905 on the side of the lower rotating gear 904 to offset, pulling the lever 906 and the driving disk 1007 at one end of the bottom to allow the fan-shaped plate 1006 between the driving disk 1007 and the hollow top disk 1005 to expand, leaking the hole in the middle, concentrating the potion, preventing the wind from blowing the potion away, and reducing the potion coverage rate.
