Description

Technical Field

[0002] The mounted spray device of fixed-wing UAV is an accessory system specially designed to be installed on fixed-wing UAV and used to perform spraying tasks (such as pesticides, fertilizers, seeds, fire extinguishing agents, etc.). This device is usually composed of several key components such as a fixed structure, a spraying structure, a connecting structure, and a power supply. The specific process is to fix the device on the UAV through the fixed structure, and then fix the water tank and other equipment to the bottom of the fixed device through the connecting structure. When the UAV is flying, the spraying structure sprays the medicine out.

[0003] As disclosed in the publication number CN109649659B, the invention discloses a mounted spray device suitable for fixed-wing UAVs and a method of using the same, wherein the mounted spray device includes a medicine box spraying module and a mounted fixing module for hanging the medicine box spraying module under the wing, wherein the medicine box spraying module includes a medicine box, a spraying assembly, and a power battery; the mounted fixing module includes a wing clamping mechanism detachably mounted under the wing and a mounting and unmounting mechanism arranged on the wing clamping mechanism for quickly replacing the medicine box spraying module, wherein the mounting and unmounting mechanism includes an electromagnetic lock, which is provided with an electromagnetic lock shaft with a horizontal telescopic function, and the medicine box is provided with a lock hole in cooperation with the electromagnetic lock shaft. The mounted spray device achieves timely replenishment of the liquid medicine by quickly replacing the medicine box spraying module, which improves work efficiency while avoiding damage to the UAV body caused by the dosing method.

[0004] In the above-mentioned prior art, a fixed structure is installed on the wing, and then the water tank is installed through an electromagnetic lock assembly. When the UAV is flying, the water pump transports the medicine liquid to the spraying water pipe, and sprays it out through the nozzle. By setting the fixed structure and the electromagnetic lock assembly, it is convenient to use a variety of UAVs and to facilitate disassembly, installation and dosing. However, when spraying medicine, the fixed-wing UAV flies at a fast speed, and the environment is windy, which will cause the medicine at the spraying point to float everywhere, resulting in the position that should be sprayed not being sprayed, and the plants grow at different heights, so the UAV can only descend in limited height, resulting in the shorter plants being unable to be sprayed evenly, and when spraying plants in the edge area, the sprayed medicine will fly out in a scattered manner, resulting in a waste of medicine.

At this time, the installation of the water tank 21 is completed. When spraying the medicine, start the water pump 23. The water pump 23 transports the medicine in the water tank 21 to the inside of the first water pipe 24, along the first water pipe 24 into the support water pipe 333, and enters the second water pipe 33 through the swivel 331, and finally sprays it out through the spray head 335.

[0042] Working principle: First, the staff deflects the movable frame 13 downward and pulls the base 12, the first support plate 122 extends from the storage slot 113, at this time, the fixed frame 11 is put on the fixed wing, and the fixed frame 11 is fixed by the locking member 132, and then the movable frame 13 is deflected upward. At this time, the movable frame 13 and the base 12 are in a vertical state, and the base 12 is pushed. The movable frame 13 intersects with the fixed frame 11, and the fixed frame 11 and the movable frame 13 are fixed by the threaded pin 131. Then, the fixed wing is clamped and fixed by the locking member 132, so that the UAV can be prevented from flying too fast, and the equipment such as the medicine box is too heavy, resulting in greater resistance during flight, causing the fixing parts to loosen and fall off, etc. Then, the water tank 21 is inserted through the mounting block 22 The water tank 21 is installed into the installation frame 111, and the deflection rotation buckle 112 is fixed to the installation block 22. At this time, the water tank 21 is installed. When spraying medicine, the water pump 23 is started. The water pump 23 transports the medicine in the water tank 21 to the inside of the first water pipe 24, enters the supporting water pipe 333 along the first water pipe 24, enters the second water pipe 33 through the rotating ring 331, and finally sprays out through the spray head 335. When the wind force is strong or the height of the plants is different, the first gear 343 is driven to rise by driving the electric push rod 34, so that the first gear 343 is meshed with the annular rack 332 and the first gear rod 322, and the motor 32 is started. The motor 32 drives the first rotating rod 321 to rotate, the first rotating rod 321 drives the first gear rod 322 to rotate, and the first gear rod 322 drives the first gear rod 322 to rotate. The wheel 343 rotates, the first gear 343 drives the annular rack 332 to deflect, the annular rack 332 drives the second water pipe 33 to deflect with the supporting water pipe 333 as the axis, and the second water pipe 33 drives the spray head 335 to move downward, thereby adjusting the spraying height of the spray head 335, shortening the distance from the plant, and avoiding the uneven spraying caused by the drone speed being too fast and the wind blowing the medicine away. Secondly, the deflection angle of the second water pipe 33 can be adjusted separately according to the different growth heights of the plants, so that comprehensive spraying can be achieved. During the deflection of the second water pipe 33, the supporting movable ring 336 slides along the trajectory of the second water pipe 33, so that the supporting movable ring 336 always supports the second water pipe 33. When the wind is strong, concentrated spraying or spraying of the edge position is required. When the plant is planted, the electric push rod 34 is shortened, so that the first gear 343 is meshed with the second gear rod 327. When the motor 32 drives the first rotating rod 321 to rotate, the second gear rod 327 is driven to rotate through the linkage of the belt 324, so that the first gear 343 is driven to rotate through the second gear rod 327, the first gear 343 drives the second gear 353 to rotate, the second gear 353 drives the connecting rod 352 to rotate, the connecting rod 352 drives the universal shaft 351 to rotate, the universal shaft 351 drives the third rotating rod 35 to rotate, the third rotating rod 35 drives the third gear 357 to rotate, the third gear 357 drives the fan gear 358 to deflect, the fan gear 358 drives the deflection rod 359 and the fixing ring 3510 to rotate, so that the soft water pipe 334 deflects an angle,Therefore, the angle of the soft water pipe 334 is adjusted according to the direction of concentrated spraying or the position of the plants in the spraying edge area to prevent the sprayed medicine from scattering and flying out, resulting in waste of medicine. The third rotating rod 35 can keep rotating after the deflection of the second water pipe 33 through the setting of the universal shaft 351.
