[0025] Further, the lower end of the drive disk and the lower end of the storage cylinder are rotationally connected through a rotary motor, a baffle is fixedly installed on one side of the lower end of the driven disk, and a push rod for pushing the baffle is fixedly installed on one side of the upper end of the drive disk.

A limit bolt is threadedly installed on the inner wall of the card slot and at one end of the loading plate.

[0033] 3. Beneficial effects

[0034] Compared with the prior art, the advantages of the present invention are as follows:

[0035] (1) In this solution, the visual sensor is fixed on the loading plate, and then the end of the suspension rod away from the loading plate is inserted into the assembly hole of the drone. By tightening the two ends of the steel wire rope, the steel wire rope slides in the wire threading hole and circumferentially tightens the suspension rod. Then, the steel wire rope is fastened, so that a plurality of suspension rods tightly clamp the drone circumferentially to suspend the loading plate on the drone. Then, the drone is used to carry the visual sensor to perform plant recognition work. Conversely, by unfastening the steel wire rope, the suspension rod inserted into the drone can be pulled out, which can facilitate the suspension or disassembly of the visual sensor on the drone to quickly start the plant recognition work of the drone, or facilitate the removal of the visual sensor on the drone for quick maintenance.

[0036] (2) In this solution, when a plant sample is obtained, the initial position of the through hole is rotated to directly below the feed hopper, and the leaf passes through the through hole and falls onto the active disk. Then, by rotating the active disk, the samples of different plants can be made to fall at different positions on the active disk, which can reduce the stacked samples in the storage cylinder, relieve the extrusion effect of other samples on the samples in the storage cylinder, and at the same time, the samples are blocked by the driven disk to reduce the samples flying into the feed hopper in the storage cylinder during the movement of the drone, so as to facilitate obtaining a sufficient amount of samples after the identification device is disassembled.

[0037] (3) When the recognition device obtains a sample in this solution, as the drone flies, air flows into the air duct along the air collecting hopper. Due to the structural characteristics of multiple air collecting hoppers arranged in a circumferential array on the outer side of the lower end of the storage cylinder, air can be poured into the air duct when the drone moves in any direction. The air flows into the heat dissipation pipe to form an air current, so that the air current can take away the heat in the storage cylinder, thereby reducing the temperature of the storage cylinder and the sample inside the storage cylinder, facilitating the refrigeration of the sample inside the recognition device, and being able to extend the storage duration of the sample.

[0038] (4) When the feeding hopper covers the blade in this solution, the air pump agitates the gas flow in the air pipe. The air pipe absorbs the air in the feeding hopper, creating a negative pressure environment in the feeding hopper, causing the feeding hopper to attract the blade and suck the blade into the feeding hopper, facilitating the blade to fall into the storage cylinder after being cut. At the same time, the filter screen blocks the blade entering the air pipe, and then the air pump is controlled to stop. Thus, the blade sample falls into the storage cylinder under the action of inertia, reducing the blade sample that detaches from the storage cylinder and facilitating obtaining a sufficient amount of samples when the recognition device is disassembled.

[0049] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0050] Embodiment:

[0051] Please refer to Figures 1 - 8 , a medium-sized UAV plant recognition device convenient for hanging, including:

[0052] Visual sensor 1, the visual sensor 1 is used to obtain the image information of plants;

[0053] Loading plate 2, the loading plate 2 is hinged to the lower end of the visual sensor 1, and a sampling mechanism is arranged at the lower end of the loading plate 2;

[0054] Suspension rod 3, a plurality of suspension rods 3 are respectively hinged to the four corners of the upper end of the loading plate 2, and the structure of the suspension rod 3 is "L" shaped;

[0055] Threading hole 4, the threading hole 4 is opened on the outside of the suspension rod 3;

[0056] Steel wire rope 5, the steel wire rope 5 is inserted into the threading hole 4.

[0057] When the present invention works, the vision sensor 1 is fixed on the loading plate 2, and then one end of the suspension rod 3 far from the loading plate 2 is inserted into the assembly hole of the drone. By tightening both ends of the steel wire rope 5, the steel wire rope 5 slides in the wire threading hole 4 and circumferentially tightens the suspension rod 3. Then, the steel wire rope 5 is fastened, so that a plurality of suspension rods 3 clamp the drone circumferentially to hang the loading plate 2 on the drone. Then, the drone carries the vision sensor 1 to perform plant recognition work. On the contrary, by unfastening the steel wire rope 5, the suspension rod 3 inserted into the drone can be pulled out, which can conveniently hang or disassemble the vision sensor 1 on the drone to quickly start the plant recognition work of the drone, or facilitate removing the vision sensor 1 on the drone for quick maintenance.

[0058] Refer to Figure 1 and Figure 5 , a wire clip 6 is clamped between both ends of the steel wire rope 5, and a wax block 7 is fixedly installed on the inner wall of the wire threading hole 4. When the steel wire rope 5 needs to be fastened, both ends of the steel wire rope 5 are clamped by the wire clip 6. On the contrary, by opening the wire clip 6, the steel wire rope 5 can be loosened. At the same time, the wax block 7 lubricates the steel wire rope 5 in the wire threading hole 4 to relieve the friction between the steel wire rope 5 and the suspension rod 3 during the tightening and loosening process.

[0059] Refer to Figure 1 and Figure 6 , the sampling mechanism includes:

[0060] A storage cylinder 8, and the storage cylinder 8 is fixedly installed at the lower end of the loading plate 2;

[0061] A feed hopper 9, and the feed hopper 9 is fixedly installed on one side of the upper end of the storage cylinder 8;

[0062] An electric telescopic rod 11, and the electric telescopic rod 11 is fixedly installed at the end of the feed hopper 9 far from the storage cylinder 8;

[0063] A cutter 10, and the cutter 10 is fixedly installed at the output end of the electric telescopic rod 11, and the output end of the electric telescopic rod 11 is parallel to the end of the feed hopper 9 far from the storage cylinder 8.

[0064] When the present invention works, the image information of the target plant is obtained through the vision sensor 1, and then the drone drives the feed hopper 9 to cover a part of the leaves of the target plant until the leaves enter the inside of the feed hopper 9. Then, the electric telescopic rod 11 pushes the cutter 10 to reciprocate along the feed inlet of the feed hopper 9 to cut off the leaves of the target plant, so that the leaves slide into the inside of the storage cylinder 8 along the feed hopper 9 to complete the sampling work of the target plant, which is convenient to cooperate with the image information of the plant to complete the plant recognition work.

[0065] Refer to Figure 4 and Figure 7 , the separation mechanism includes:

[0066] The driving disk 16 is rotatably installed on the lower wall inside the storage cylinder 8;

[0067] The driven disk 17 is rotatably installed inside the storage cylinder 8. The height of the driven disk 17 is greater than that of the driving disk 16. The outer side of the driven disk 17 and the inner side of the storage cylinder 8 are rotatably connected through a bearing. This technical solution is an existing technology and is not shown in the figure;

[0068] The through hole 18 is opened at the lower end of the driven disk 17.

[0069] When obtaining a plant sample, rotate the initial position of the through hole 18 to directly below the feed hopper 9. The leaf passes through the through hole 18 and falls onto the driving disk 16. Then, by rotating the driving disk 16, the samples of different plants can be made to fall at different positions on the driving disk 16, which can reduce the stacked samples in the storage cylinder 8, relieve the extrusion effect of other samples on the samples in the storage cylinder 8, and at the same time, the samples are blocked by the driven disk 17 to reduce the samples that fly into the feed hopper 9 during the movement of the drone in the storage cylinder 8, so as to facilitate obtaining a sufficient amount of samples after the identification device is disassembled.

[0070] Refer to Figure 1 and Figure 2 , the refrigeration mechanism includes:

[0071] The air collecting hoppers 23 are distributed in a circumferential array on the outer side of the lower end of the storage cylinder 8;

[0072] The air guide pipe 24 is fixedly installed at one end of the air collecting hopper 23;

[0073] One end of the heat dissipation pipe 25 is fixedly connected to the end of the air guide pipe 24 away from the air guide pipe 24, and the heat dissipation pipe 25 is spirally wound around the outer side of the storage cylinder 8.

[0074] When the identification device obtains a sample, when the drone flies, the air flows into the air guide pipe 24 along the air collecting hopper 23. Due to the structural characteristics of the multiple air collecting hoppers 23 distributed in a circumferential array on the outer side of the lower end of the storage cylinder 8, air can be poured into the air guide pipe 24 when the drone moves in any direction. The air flows into the heat dissipation pipe 25 to form an air flow, so that the air flow takes away the heat in the storage cylinder 8 to reduce the temperature of the storage cylinder 8 and the samples inside the storage cylinder 8, thereby facilitating refrigerating the samples inside the identification device and being able to extend the storage duration of the samples.

[0075] Refer to Figure 4 and Figure 7, multiple first sample slots 21 are arranged in a circumferential array along the upper end of the driving disk 16, and multiple second sample slots 22 are arranged in a circumferential array along the upper end of the driven disk 17. Moreover, one second sample slot 22 communicates with the upper end of the through hole 18. When the sample falls into the storage cylinder 8, the sample is placed through the first sample slots 21 and the second sample slots 22, which is convenient for separating the samples and reducing the mutual contact between the samples.

[0076] Refer to Figure 4 and Figure 6 , an air pipe 12 is fixedly installed inside the feed hopper 9. One end of the air pipe 12 is fixedly installed with a filter net 14 inside the feed hopper 9, and one end of the air pipe 12 extends out of the inside of the feed hopper 9 and is equipped with an air pump 13. When the feed hopper 9 covers the blade, the air pump 13 agitates the gas flow in the air pipe 12, the air pipe 12 absorbs the air in the feed hopper 9, and a negative pressure environment is generated in the feed hopper 9, so that the feed hopper 9 attracts the blade to suck the blade into the feed hopper 9. This is convenient for the blade to fall into the storage cylinder 8 after being cut. At the same time, the filter net 14 blocks the blade entering the air pipe 12, and then the air pump 13 is controlled to stop. Thus, the blade sample falls into the storage cylinder 8 under the action of inertia, reducing the blade sample that detaches from the storage cylinder 8 and facilitating the acquisition of a sufficient amount of samples when the identification device is disassembled.

[0077] Refer to Figure 4 and Figure 7 , the lower end of the driving disk 16 and the lower end of the storage cylinder 8 are rotationally connected through a rotary motor 15. One side of the lower end of the driven disk 17 is fixedly installed with a baffle 20, and one side of the upper end of the driving disk 16 is fixedly installed with a push rod 19 for pushing the baffle 20. When the electric telescopic rod 11 works for a period of time, the sample passes through the through hole 18 until it falls into the first sample slot 21. Then, the rotary motor 15 is controlled to drive the driving disk 16 to rotate by a certain angle, and the first sample slot 21 rotates relative to the through hole 18, so that the empty first sample slots 21 are successively vertically aligned with the through hole 18 until the rotary motor 15 works a certain number of times. Thus, the first sample slots 21 on the driving disk 16 are filled with samples. At the same time, the push rod 19 first moves away from the baffle 20 and then approaches the baffle 20 until the baffle 20 is pushed by the push rod 19 and the driven disk 17 is rotated by the driving disk 16, and then the second sample slots 22 on the driven disk 17 are filled with samples.

[0078] Refer to Figure 4 and Figure 8 , multiple refrigerators 26 are fixedly installed on the outer side of the heat dissipation pipe 25, and multiple ice blocks 27 are arranged inside the refrigerators 26. When the heat dissipation pipe 25 works, the ice blocks 27 in the refrigerators 26 melt to absorb heat, and part of the heat of the heat dissipation pipe 25 is transferred to the refrigerators 26 to reduce the temperature of the air flow in the heat dissipation pipe 25, which is convenient for refrigerating the samples in the storage cylinder 8 through the heat dissipation pipe 25.

[0079] Refer to Figure 1 ,Figure 3 and Figure 6 On one side of the lower end of the loading plate 2, a clamping groove 28 is provided. A sliding plate 29 is slidably connected between the upper end of the storage cylinder 8 and the inner side of the clamping groove 28. A limit bolt 30 is threadedly installed on the inner wall of the clamping groove 28 and at one end of the loading plate 2. Finally, when the drone returns, by unscrewing the limit bolt 30, it is convenient to push and pull the sliding plate 29, and the sliding plate 29 disengages from the loading plate 2 along the clamping groove 28, so that the storage cylinder 8 is opened, facilitating the extraction of the sample in the storage cylinder 8.

[0080] Working principle: When the present invention works, the vision sensor 1 is fixed on the loading plate 2. Then, the end of the suspension rod 3 away from the loading plate 2 is inserted into the assembly hole of the drone. By tightening the two ends of the steel wire rope 5, the steel wire rope 5 slides in the wire passing hole 4 and circumferentially tightens the suspension rod 3. Subsequently, the steel wire rope 5 is fastened, enabling multiple suspension rods 3 to circumferentially clamp the drone, so as to suspend the loading plate 2 on the drone. Then, the drone carries the vision sensor 1 to perform plant recognition work. On the contrary, by untying the steel wire rope 5, the suspension rod 3 inserted into the drone can be pulled out, which can conveniently suspend or disassemble the vision sensor 1 on the drone to quickly start the plant recognition work of the drone, or facilitate removing the vision sensor 1 on the drone for quick maintenance.

[0081] When obtaining a plant sample, rotate the initial position of the through hole 18 to directly below the feed hopper 9. The leaves pass through the through hole 18 and fall onto the active disk 16. Then, by rotating the active disk 16, the samples of different plants can be made to fall at different positions on the active disk 16, which can reduce the stacked samples in the storage cylinder 8, relieve the extrusion effect of other samples on the samples in the storage cylinder 8, and at the same time, the driven disk 17 blocks the samples, reducing the samples that fly into the feed hopper 9 during the movement of the drone in the storage cylinder 8, so as to facilitate obtaining a sufficient amount of samples after the recognition device is disassembled.

[0082] When the recognition device obtains a sample, when the drone is flying, air flows along the air collecting hopper 23 into the air guide pipe 24. Due to the structural characteristics of multiple air collecting hoppers 23 being arranged in a circumferential array on the outer side of the lower end of the storage cylinder 8, air can be poured into the air guide pipe 24 when the drone moves in any direction. The air flows into the heat dissipation pipe 25 to form an air current, so that the air current takes away the heat in the storage cylinder 8, reducing the temperature of the storage cylinder 8 and the samples inside the storage cylinder 8, thereby facilitating the refrigeration of the samples inside the recognition device and extending the storage duration of the samples.

[0083] When the feed hopper 9 covers the blade, the air pump 13 is used to agitate the gas flow in the air pipe 12. The air pipe 12 absorbs the air in the feed hopper 9, creating a negative pressure environment in the feed hopper 9, which causes the feed hopper 9 to attract the blade and suck the blade into the feed hopper 9. This facilitates the blade to fall into the storage cylinder 8 after being cut. At the same time, the filter screen 14 blocks the blades entering the air pipe 12, and then the air pump 13 is controlled to stop. Thus, the blade sample falls into the storage cylinder 8 under the action of inertia, reducing the blade samples that fall out of the storage cylinder 8 and facilitating the acquisition of a sufficient amount of samples when the identification device is disassembled.

[0084] The above is only a preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
