Description

Technical Field

[0001] The invention relates to the technical field of plant protection sampling, and in particular to a plant protection sampling drone. Background Art

[0002] In the process of modern agricultural production, the monitoring and prevention of pests and diseases is of vital importance. The traditional method of plant protection sampling mainly relies on manual operation. Farmers or plant protection personnel need to go deep into the fields to manually collect samples of crop leaves, fruits, soil, etc., and then bring them back to the laboratory for analysis and testing. This method is not only time-consuming and laborious, but also requires walking in the fields when picking manually, which may cause trampling and damage to crops.

[0003] With the rapid development of drone technology, its application in the agricultural field has become increasingly widespread. Ordinary plant protection drones have realized functions such as plant protection sampling, which greatly improved the work efficiency. However, the disadvantages of existing plant protection drones are that, on the one hand, they can only sample one type of vegetation at a time. If multiple types are collected at one time, it is easy to confuse the samples; on the other hand, because drones use propeller lift to float, when the drone falls on the vegetation, the reaction force of its lift will blow the vegetation away, making it difficult to sample.

[0004] At present, there is a lack of a sampling plant protection drone to solve the above problems. Summary of the invention

[0005] The present invention provides a plant protection sampling drone, which is used to solve the defects in the prior art that samples are easily confused and difficult to sample when multiple samples are picked.

Detailed implementation manners

[0037] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.

[0038] As mentioned above, the disadvantages of existing sampling plant protection drones are that, on the one hand, they can only sample one type of vegetation at a time. If multiple types are collected at a time, the samples are easily confused. On the other hand, since the drone uses propeller lift to float in the air, when the drone falls on the vegetation, the reaction force of its lift will blow the vegetation away, making it difficult to sample.

[0039] In view of this, the present invention provides a plant protection sampling drone, which can store the collected plant samples in batches and avoid the influence of the drone propeller on the collection. The present invention is achieved in the following ways:

[0040] like Figures 1-12 As shown, the present invention provides a plant protection sampling drone, including a drone body 1, and also includes a sampling component. The sampling component is arranged below the body 1, and includes: a shell part, a sampling part, a dial part and a collecting part. Among them, the shell part includes an outer shell 2, and the outer shell 2 is cylindrical, and an opening that passes through from top to bottom is arranged therein. The outer shell 2 is fixedly connected to the bottom of the body 1, and a top plate 3 is fixedly connected to the bottom of the outer shell 2. The top plate 3 and the outer shell 2 form a basin-shaped body, and a cavity is formed therebetween. A plurality of sampling ports 4 are provided on the top plate 3. At the same time, the collecting part is arranged in the sampling port 4 for storing different plant samples. In order to prevent different plant samples from being confused, an embodiment of the present invention also provides a dial part therein, and the dial part divides the cavity into a plurality of areas, each of which can store a plant sample. Next, the sampling part is set at the bottom of the top plate 3, and the sampling part includes a plurality of cutters 5. The cutters 5 cut and sample the plant samples entering the sampling part. After the sampling is completed, the dial part will push it away and finally drop it into the collection part, thus completing the sampling.

[0041] Therefore, the embodiment of the present invention guides the vegetation into a predetermined semi-enclosed area through the above method, so as to avoid the wind caused by the propeller of the drone blowing away the vegetation and causing sampling difficulties, and then cuts the sample through the cutter 5, and then dials the sample into the collection part through the dial part, so as to separate different vegetation samples and avoid confusion of multiple samples. The present invention solves the defects of the prior art that samples are easily confused and difficult to sample when picking multiple samples through the above method, and greatly improves the efficiency of plant protection sampling.

[0042] In order to further explain the technical principle of a plant protection sampling drone provided by the embodiment of the present invention, the present invention also provides another preferred embodiment, such as Figures 3-4As shown, in another preferred embodiment of the present invention, the above-mentioned collecting part includes a sampling tray 6, and the sampling tray 6 is threadedly connected to the sampling port 4. Each sampling tray 6 is covered with a sampling cover 7, and the sampling cover 7 is provided with a through hole 8, or no through hole 8 is provided. If no through hole 8 is provided, the sampling tray 6 may not be placed in the sampling port 4, and the sampled plant sample is placed on the sampling cover 7. If a through hole 8 is provided, the diameters of the through holes 8 on different sampling covers 7 are different. A through hole 8 with a small diameter can accommodate a small volume of plant samples. At this time, a large volume of plant samples will not fall on the sampling tray 6 when passing through the through hole 8, so that it moves in the cavity as the dial part is turned until it encounters a through hole 8 that meets its diameter and then falls. In this way, different plant samples can be accommodated to play a role in classified storage.

[0043] like Figures 4-6 As shown, in another preferred embodiment of the present invention, the dial part includes a rotating cylinder 9, which is rotatably connected to the middle of the top of the top plate 3. The outer periphery of the rotating cylinder 9 is fixedly connected with a plurality of partitions 10, which divide the cavity into a plurality of independent spaces, each of which corresponds to a sampling port 4, and can store different plant samples in a classified manner. By driving the rotating cylinder 9 to rotate on the top plate 3, the partition 10 is driven to dial the plant sample. Specifically, a through hole 11 is provided on the top plate 3, and the dial part also includes a pressing column 12, which is arranged inside the rotating cylinder 9 (such as Figure 5 As shown in the figure, a spring 13 is fixedly connected to the bottom of the pressing column 12, the bottom of the spring 13 passes through the through hole 11 and is fixedly connected to the shell 14, the shell 14 is fixedly connected to the bottom of the top plate 3, a damper 25 is arranged in the spring 13, a plurality of limit columns 15 are fixedly connected to the pressing column 12, a limit groove 16 is provided on the inner side wall of the rotating cylinder 9, the limit groove 16 is divided into a plurality of continuously combined recessed portions 17 and convex portions 18, a top cover 19 is fixedly connected to the top of the rotating cylinder 9, a telescopic cylinder 20 is fixedly connected to the top of the pressing column 12, and the output shaft of the telescopic cylinder 20 is fixedly connected to the top of the pressing column 12.

[0044] Therefore, when the present invention is implemented, the telescopic cylinder 20 is telescopically pushed to drive the pressing column 12 to move slightly up and down, and in this process, the spring 13 and the damper 25 are squeezed, and the pressing column 12 is reset by the spring 13 and the damper 25. During the reciprocating up and down movement of the pressing column 12, the limit column 15 thereon slides inside the limit groove 16. Figure 12Shows the state after the rotating cylinder 9 is horizontally unfolded. As shown in the figure, the limiting slots 16 on the rotating cylinder 9 have a number of continuous concave portions 17 and convex portions 18. When the first limiting post 15 slides along the groove line through these continuous concave portions 17 and convex portions 18, it will drive the rotating cylinder 9 to rotate, thereby driving the partition plate 10 to rotate, and finally driving the movement of the plant samples sampled in the space divided by the partition plate 10, so that they can fall into the predetermined sampling port 4.

[0045] As Figures 7-10 shown, in another preferred embodiment of the present invention, the sampling part includes a connecting cover 21 and a guiding disc 22 which are distributed up and down. The cutting knife 5 is arranged between the connecting cover 21 and the guiding disc 22, and the connecting cover 21 and the guiding disc 22 are connected to each other by a number of connecting posts 23. An inlet sample port 24 is opened at the top of the connecting cover 21, and a sampling port 4 is opened on the top disc 3. The inlet sample port 24 and the sampling port 4 are communicated. In actual use, the drone slowly descends and hovers from top to bottom, and the wind generated by its propeller will disperse the plants, making it difficult to sample. However, in another preferred embodiment of the present invention, the outer periphery of the guiding disc 22 is in a cylindrical shape, and its inner side is in an inclined shape that is narrower at the top and wider at the bottom, which can cover the plants in a semi-closed manner so that they are not affected by the wind. At the same time, as the drone slowly descends, the plant stems and leaves slowly enter the opening provided in the guiding disc 22 through the inner side of the guiding disc 22, and finally come out from the inlet sample port 24 and are cut by the cutting knife 5 arranged between the connecting cover 21 and the guiding disc 22. Finally, the cut plant samples enter the space divided by the above-mentioned partition plate 10 and finally fall into the sampling port 4.

[0046] The driving of the cutting knife 5 depends on the cutting mechanism. In another preferred embodiment of the present invention, the above-mentioned cutting mechanism is arranged between the connecting cover 21 and the guiding disc 22 and includes a toothed ring 27. The toothed ring 27 is arranged between the connecting cover 21 and the guiding disc 22. A number of evenly distributed rotating grooves 28 are opened on the toothed ring 27. A second limiting post 34 is arranged in the rotating groove 28, and the second limiting post 34 is fixedly connected to the connecting cover 21. A fixed ring 29 is arranged inside the toothed ring 27, and the fixed ring 29 is fixedly connected to the top end of the guiding disc 22. One end of the fixed ring 29 is rotatably connected to the cutting knife 5, and the end of the cutting knife 5 away from the fixed ring 29 is rotatably connected to a rotating rod 30, and the rotating rod 30 is rotatably connected to the toothed ring 27. At the same time, a gear 31 is meshed with the outer periphery of the toothed ring 27. A motor 32 is fixedly connected to the gear 31, a motor seat 33 is fixedly connected to the motor 32, and the motor seat 33 is fixedly connected to the outer periphery of the guiding disc 22.

[0047] Therefore, when the present invention is specifically implemented, the motor 32 started by being powered on rotates, driving the gear 31 to rotate. Since the gear 31 is meshed with the toothed ring 27, it finally drives the toothed ring 27 to rotate. As Figure 10As shown, during the rotation of the gear ring 27, the rotating rod 30 will be driven to move. The movement of the rotating rod 30 drives the cutting knife 5 to rotate, and finally realizes the opening and closing of the cutting knife 5. When the rotating groove 28 touches the second limiting post 34 from one side wall to the other side wall, the cutting knife 5 just completes an opening and closing cycle. Thus, the cutting of the plant sample deep into the fixing ring 29 is completed, and then the above-mentioned process is continued.

[0048] Finally, both sides of the bottom of the top plate 3 are fixedly connected with cameras 26, and both cameras 26 on both sides are connected to the control port of the machine body 1 to assist in monitoring the sampling of vegetation.

[0049] For example, a plant sampling plant protection UAV provided by the present invention, through the above design, compared with the prior art, has at least the following advantages including but not limited to:

[0050] (1) By means of the dial part, the cavity in the outer shell 1 is divided into several spaces, which can accommodate different categories of plant samples, avoiding sample confusion, enabling the plant protection sampling UAV to have the ability of multi-sample sampling, and greatly improving the sampling efficiency.

[0051] (2) The sampling part provides a semi-closed environment for the collection of plant samples and guides the plant samples into the cutting range of the cutting knife 5 to complete the cutting, avoiding the influence of the wind generated by the propeller on the plant samples. The sampling effect is improved.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
