Description
Technical Field
[0001] This invention relates to the field of intelligent agricultural power machinery technology, and in particular to an airborne operation device that integrates remote sensing and precision operation. Background Technology
[0002] As a key component of intelligent agricultural power machinery, drones are an important carrier for realizing the automation and precision of field management operations. In different agronomic stages such as irrigation and fertilization, drones are required not only to be able to quickly switch operating media (such as water and liquid fertilizer), but also to adjust the droplet size and spraying range synchronously and precisely according to actual needs, so as to achieve water and fertilizer conservation while ensuring that crops obtain uniform and effective application results.
[0003] Currently, there are several drone-mounted devices in the industry designed to improve the adaptability of agricultural machinery operations. For example, Chinese patent CN210641386U discloses a fertilizer application drone, including a drone body and a spraying device. The drone body has multiple legs, and the spraying device is fixed below the drone body. The spraying device includes a drive motor, a material hopper, and a chassis. The output shaft of the drive motor has a first gear disk, and a second gear disk is rotatably mounted at the center of the upper end of the material hopper. The first and second gear disks are connected by a belt. The upper end of the material hopper has a feeding port, a fixed plate is located at the lower part of the hopper, and a discharge port is located at the center of the lower end of the hopper. A rotating shaft is located inside the hopper, with its top end fixed to the center of the second gear disk, and its lower end rotating through the fixed plate and the discharge port, and its bottom end fixed to the chassis. The upper surface of the chassis has multiple baffle strips radiating from the center. This invention has the advantages of uniform fertilizer application, high work efficiency, less fertilizer waste, and low labor costs.
[0004] However, these existing solutions still have significant shortcomings in practical applications and are difficult to meet the requirements of efficient and precise integrated operations: First, switching between operating modes usually requires manual replacement of parts, which seriously affects the efficiency of continuous operation; second, the spraying function of existing devices is relatively simple and cannot simultaneously complete liquid switching, droplet size adjustment and spray width adjustment in one operation. This results in existing equipment often having a complex structure, large weight and low reliability, which makes it difficult to meet the requirements of lightweight and highly reliable operation of drones, thus limiting the promotion and application of precision agriculture technology.

[0020] The following is in conjunction with the appendix Figures 1 to 6 This application will be described in further detail.
[0021] This application discloses an airborne operation device that integrates remote sensing and precision application. When used in conjunction with a drone for aerial operations, this application precisely controls the amount of work done by controlling the size of the spraying area and the size of the sprayed particles, thereby achieving refined operation of the target area.
[0022] Reference Figures 1 to 2 As shown in this embodiment, an airborne operation device integrating remote sensing and precision operation is disclosed, including: a drone 1, a carrier box 2, a storage cavity 21, a nozzle 3, a switching and conveying mechanism 4, a lifting mechanism 5, a support mechanism 6, and an expanding area nozzle 7. The drone 1 is a fixed base, and the carrier box 2 is installed at the lower end of the drone 1 through a connector. The storage cavity 21 is symmetrically opened on the left and right sides inside the carrier box 2. The nozzle 3 is installed at the lower edge of the carrier box 2. The switching and conveying mechanism 4 is connected between the carrier box 2 and the nozzle 3. The lifting mechanism 5 is installed at the outside of the carrier box 2. The support mechanism 6 is symmetrically installed on the left and right sides at the lower end of the lifting mechanism 5. The expanding area nozzle 7 is provided inside the support mechanism 6 and can slide up and down. The spray trajectory of the nozzle 3 and the expanding area nozzle 7 can be controlled by the lifting and lowering of the support mechanism 6.
[0023] In actual operation, the drone 1 drives the application to perform aerial operations. When ascending, the lifting mechanism 5 drives the support mechanism 6 to rise to the first position to avoid the support mechanism 6 blocking its spraying area during spraying. During subsequent spraying, the conveying mechanism 4 is switched to output clean water or water-soluble fertilizer from the storage chamber 21 according to the actual situation (the left storage chamber 21 stores clean water, and the right storage chamber 21 stores water-soluble fertilizer). When watering is required, the nozzle 3 sprays clean water with a larger droplet diameter. When fertilization is required, the lifting mechanism 5 drives the support mechanism 6 to continue to rise to the second position, so that the expansion area nozzle 7 is aligned with the nozzle 3. At this time, the nozzle 3 works in a small droplet diameter mode, working in conjunction with the expansion area nozzle 7 to achieve wide-area, fine-mist fertilization, thereby realizing the aerial switching and integrated precise application of irrigation and fertilization modes.
[0024] It should be noted that the operation mode of this application can be controlled based on remote sensing information. By analyzing the multispectral or image data of the field acquired by the UAV, the water or fertilizer requirement of the crop can be determined and corresponding control commands can be generated. According to the commands, this application can switch the conveying mechanism 4 to output the clean water or water-soluble fertilizer in the storage chamber 21.
[0025] Reference Figure 3 As shown, the lower end face of the storage cavity 21 is configured as an arc surface that gradually curves downward from the outside to the inside.
[0026] When the drone 1 encounters wind resistance during flight, it sways. The curved surface design ensures that the liquid in the storage chamber 21 can still be concentrated around the liquid outlet at the bottom of the storage chamber 21 when it sways or when the amount is small.
[0027] Reference Figure 5 As shown, the nozzle 3 includes a nozzle 31, which is installed at the lower edge of the carrier box 2. An adjusting head 32 is slidably provided at the lower end of the nozzle 31. The size of the ejected particles can be controlled by raising and lowering the adjusting head 32. A switching element 33 is slidably provided inside the nozzle 31. A corresponding hole 34 is provided at the upper end of the nozzle 31, and a corresponding cavity 35 is provided at the lower end of the carrier box 2. The corresponding hole 34 and the corresponding cavity 35 are connected.
[0028] Reference Figure 4 , Figure 5 As shown, the adjusting head 32 includes a spiral frame 321, which is fitted vertically at the lower end of the nozzle 31. An extrusion member 322 is installed on the upper side of the outer end of the spiral frame 321. A connecting plate 323 is evenly installed inside the spiral frame 321 from left to right. A blocking member 324 is evenly installed on the connecting plate 323 from front to back. The blocking member 324 has a pointed cone structure. The rising blocking member 324 can partially block the nozzle 311, reducing its diameter, so that a smaller droplet diameter can be ejected subsequently.
[0029] Reference Figure 5 As shown, the switching component 33 includes a partition 331, which is horizontally slidably disposed in the inner cavity of the nozzle 31. The lower end of the inner cavity is evenly provided with spray holes 311, which correspond to the position of the blocking component 324. The outer end of the partition 331 is equipped with a squeezing head 332, which is slidably disposed in the horizontal groove opened in the nozzle 31, and the squeezing head 332 and the horizontal groove are elastically connected. The upper end of the partition 331 is provided with an alignment hole 333, and the initial position of the alignment hole 333 is misaligned with the corresponding hole 34, which makes the corresponding hole 34 temporarily sealed.
[0030] In actual operation, the liquid in the storage chamber 21 is transported to the inner cavity of the nozzle by the switching conveying mechanism 4 and then sprayed out from the spray hole 311. When watering, clean water is sprayed out from the spray hole 311, resulting in a larger droplet diameter. When fertilization is required, the lifting mechanism 5 drives the support mechanism 6 to continue rising to the second position. During the rising process, the extrusion component 322 is pushed up, and the synchronously rising return frame 321 drives the blocking component 324 to partially block the spray hole 311, reducing its diameter. The rising extrusion component... The component 311 squeezes the extrusion head 332 to move it horizontally inward, and the partition component 331 moves inward synchronously. When it rises to the second position, the alignment hole 333 on the partition component 331 aligns with the corresponding hole 34, and the longitudinal part of the partition component 331 reduces the inner cavity capacity of the nozzle 31. Part of the liquid entering the inner cavity enters the corresponding cavity 35 from the corresponding hole 34 and is finally sprayed out from the small droplet diameter of the expanded area nozzle 7. The other part of the liquid is still sprayed out from the small droplet diameter of the spray hole 311 of the constricted hole, thereby realizing the wide-range, fine mist fertilization operation.
[0031] Reference Figure 3 , Figure 6 As shown, the switching conveying mechanism 4 includes a conveying pump 41, which is installed on the lower end face of the carrier box 2. A diversion pipe 42 is connected between the output port of the conveying pump 41 and the nozzle 31. The input port of the conveying pump 41 is connected to the confluence cavity 421 opened at the lower end of the carrier box 2. A connecting cavity 43 is symmetrically opened on the upper end of the confluence cavity 421. The upper end of the connecting cavity 43 is connected to the storage cavity 21. A movable groove is opened at the lower end of the carrier box 2. A switching plate 44 is horizontally slidably arranged inside the movable groove. A clear water port 45 and a liquid medicine port 46 are opened sequentially from left to right on the right end of the switching plate 44. A squeezing rod 47 is installed on the left end of the switching plate 44, and the squeezing rod 47 is elastically connected to the movable groove. An arc-shaped squeezing surface is provided on the left end of the squeezing rod 47. A filter screen is provided inside the liquid medicine port 46. The filter screen intercepts and retains the granular fertilizer that is not completely dissolved in the aqueous solution.
[0032] During the actual switching process, when the switching plate 44 is not displaced due to compression, the clean water inlet 45 in the switching plate 44 is aligned with the storage chamber 21 on the left (the storage chamber 21 on the right is misaligned with the liquid inlet 46). The clean water in the storage chamber 21 is output by the delivery pump 41. After the switching plate 44 is compressed by the rising U-shaped plate 51, it moves to the right, so that the liquid inlet 46 in the switching plate 44 is aligned with the storage chamber 21 on the right (the clean water inlet 45 is misaligned with the storage chamber 21 on the left). The liquid fertilizer in the storage chamber 21 is output by the delivery pump 41.
[0033] Reference Figure 1 , Figure 5 As shown, the lifting mechanism 5 includes a return plate 51, and an electric push rod 52 is connected between the return plate 51 and the carrier box 2.
[0034] Reference Figure 5 As shown, the support mechanism 6 includes an L-shaped frame 61, the upper end of which is installed at the lower end of the conformal plate 51, and a push plate 62 is installed at the lower end of the inner side wall of the L-shaped frame 61. The push plate 62 corresponds to the position of the extruder 322.
[0035] Reference Figure 5 As shown, the expanded area nozzle 7 includes a lifting rod 71, and the lifting rod 71 has an inverted L-shaped conveying cavity 72 inside. The lower outer side of the conveying cavity 72 has an atomizing hole. The inner middle of the L-shaped frame 61 is provided with a connecting interface 611, and the positions of the connecting interface 611, the upper inlet of the conveying cavity 72, and the outer interface of the corresponding cavity 35 are corresponding. The upper end of the lifting rod 71 is connected to a movable rod 73, which is slidably disposed inside the L-shaped frame 61.
[0036] When fertilization is required, the electric push rod 52 drives the return plate 51 and L-shaped frame 6 to continue rising to the second position. During the rising process, the push plate 62 pushes the extrusion member 322 to rise. The return frame 321, which rises synchronously, drives the blocking member 324 to partially block the spray hole 311, reducing its diameter. The rising extrusion member 311 squeezes the extrusion head 332 to move it horizontally inward. The partition member 331 moves inward synchronously. When it rises to the second position, the positions of the interface 611, the upper inlet of the conveying chamber 72, and the outer interface of the corresponding chamber 35 are aligned. Part of the liquid entering the inner cavity enters the corresponding chamber 35 and the conveying chamber 72 from the corresponding hole 34 and is then sprayed out from the atomizing hole with a small droplet diameter. The other part of the liquid is still sprayed out from the spray hole 311 of the constricted hole with a small droplet diameter, thereby realizing a wide-range, fine mist fertilization operation.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
