Description

Technical Field

[0001] This utility model relates to the field of pest and disease control technology, and in particular to a spraying device for pest and disease control. Background Technology

[0002] In today's agricultural sector, pests and diseases are frequent, seriously threatening crop growth and yields. To address this situation, pest and disease control technologies have emerged. Their purpose is not only to efficiently eliminate pests and diseases and ensure the yield and quality of agricultural products, but also to reduce control costs and minimize environmental and ecological damage. Using this technology, the types and severity of pests and diseases can be accurately identified, allowing for targeted measures to be taken. This avoids excessive pesticide use, minimizes losses in a timely manner, and improves control efficiency. In large areas of farmland or areas with complex terrain, spraying drones are proving invaluable. They are not limited by terrain, can quickly move around, and spray pesticides evenly. In areas that are difficult for humans to reach, they effectively ensure the smooth progress of pest and disease control work and promote agriculture towards intelligence and efficiency.

[0003] When using agricultural spraying drones and reverse spraying, the installation of existing agricultural spraying drones and spraying devices is not convenient enough, which affects the efficiency of spraying. At the same time, the loading of materials for existing agricultural spraying drones is very cumbersome, which will reduce the production efficiency of crops.

[0004] To address the aforementioned issues, an existing patent (publication number: CN215904740U) proposes a spraying device for pest and disease control. This device involves a spraying drone with a spraying shell mounted on its bottom, symmetrically fitted with support frames on the bottom of the drone, and a nozzle mounted on the bottom of the drone to securely connect the drone and the spraying shell. The spraying shell contains a loading mechanism for agricultural pesticides, and the spraying shell and loading mechanism are fixedly positioned. This invention provides a spraying drone spraying device that, through the installation of the spraying device, loading mechanism, and fixing mechanism, ensures rapid installation of the agricultural spraying drone and spraying device, guarantees spraying efficiency, and facilitates loading, thereby improving crop production efficiency.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, when spraying pesticides on large-scale agricultural planting environments, the small capacity of the spraying drone's tank makes it impossible to complete the entire spraying operation in a single trip. Frequent return trips for refilling are necessary, resulting in lengthy and cumbersome spraying operations.

[0006] Therefore, a spraying device for pest and disease control is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a spraying device for pest and disease control, which can solve the problems of existing spraying drones having insufficient counterweight to carry the pesticide solution, requiring repeated replenishment of the solution during spraying, and resulting in long operation times.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a spraying device for pest and disease control, including a spraying drone, wherein an autonomous resupply mechanism is movably connected to the bottom of the spraying drone, and an auxiliary positioning mechanism is movably connected to the top of the autonomous resupply mechanism;

[0009] The autonomous resupply mechanism includes an external support frame, a medicine storage tank, a drone landing pad, a refueling port, and a positioning component.

[0011] Preferably, the two sides of the bottom outer side of the nested telescopic positioning beam are threadedly connected to a second electric bidirectional threaded rod, and the second electric bidirectional threaded rod is movably connected to the outside of the nested telescopic positioning beam.

[0012] Preferably, a distance measuring sensor is movably connected to the inner side of the nested telescopic positioning beam.

The application also includes a positioning component that can adjust the landing point of the spraying drone after it lands on the drone landing pad so that it is positioned above the resupply port for resupply.

[0019] 2. By setting up an auxiliary positioning mechanism, this application can further assist in positioning the spraying drone on the drone landing pad, ultimately placing it in the center of the drone landing pad, thereby facilitating the replenishment of pesticide solution and preventing the rapid docking structure from failing to dock with the spraying drone's pesticide tank after repeated attempts.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A spraying device for pest and disease control includes a spraying drone 1, an autonomous refueling mechanism 2 movably connected to the bottom of the spraying drone 1, and an auxiliary positioning mechanism 3 movably connected to the top of the autonomous refueling mechanism 2.

[0029] The autonomous resupply mechanism 2 includes an outer support frame 21, a medicine storage tank 22, a drone landing pad 23, a refueling port 24, and a positioning component 25. The spraying drone 1 is set on the top of the drone landing pad 23, the refueling port 24 is opened on the inner side of the drone landing pad 23, the refueling port 24 is set at the bottom of the spraying drone 1, the outer support frame 21 is fixedly connected to the bottom of the drone landing pad 23, the medicine storage tank 22 is fixedly connected to the inner side of the outer support frame 21, and the medicine storage tank 22 is set at the bottom of the refueling port 24.

[0030] In this embodiment: the pesticide supply point of the spraying drone 1 is composed of the outer support frame 21, the pesticide storage pipe, the drone landing pad 23 and the feed inlet 24, and is set at multiple points in the planting environment. Then, the positioning component 25 can position the spraying drone 1 on the drone landing pad 23 so that it is positioned at the top of the feed inlet 24.

[0031] Specifically, such as Figure 1 , Figure 5 As shown, a nested telescopic positioning beam 31 is slidably connected to the top of the drone landing pad 23. A linkage block 32 is fixedly connected to the bottom of the outer side of the nested telescopic positioning beam 31. A first electric bidirectional threaded rod 33 is threadedly connected to the inner side of the linkage block 32. The first electric bidirectional threaded rod 33 is movably connected to the inner side of the drone landing pad 23.

[0032] Specifically, such as Figure 1 , Figure 5 As shown, the two sides of the bottom outer side of the nested telescopic positioning beam 31 are threadedly connected to the second electric bidirectional threaded rod 34, which is movably connected to the outside of the nested telescopic positioning beam 31.

[0033] Specifically, such as Figure 1 , Figure 5 As shown, a distance measuring sensor 35 is movably connected to the inner side of the nested telescopic positioning beam 31.

[0034] In this embodiment: the distance between the positioning rods 25a is determined by the distance measuring sensor 35 on the inner side of the outermost extension of the nested telescopic positioning beams 31 on both sides, and the second electric bidirectional threaded rod 34 is driven to extend and retract the nested telescopic positioning beams 31 to adapt to different spacing of the spraying drone 1. After adjustment, the first electric bidirectional threaded rod 33 pushes the spraying drone 1 with the two side beams inward to approach the center of the drone landing pad 23, and assists in positioning it directly above the feeding port 24.

[0035] Specifically, such as Figure 3 , Figure 4 As shown, a positioning rod 25a is slidably connected to the top of the drone landing pad 23. An elastic contact pad 25b is fixedly connected to the outside of the positioning rod 25a. A linkage rod 25c is fixedly connected to the front of the positioning rod 25a. A support plate 25d is fixedly connected to the front of the outer support frame 21. The linkage rod 25c is located on the front of the support plate 25d.

[0036] Specifically, such as Figure 3 , Figure 4 As shown, an electric turntable 25e is movably connected to the front side of the support plate 25d, and a pulling arm 25f is rotatably connected to the outer side of both the electric turntable 25e and the connecting rod 25c.

[0037] In this embodiment: the electric turntable 25e rotates, and the rotation is extended by the pulling arm 25f, which pulls the two connecting rods 25c inward, and drives the positioning rod 25a inward as well. At this time, the elastic contact pad 25b contacts the bottom landing gear 7 of the spraying drone 1 and pushes it slowly. After it can no longer move, it stops pushing and retains a certain travel distance to form a limit guide rail.

[0038] Specifically, such as Figure 2 As shown, a medicine tank 4 is movably connected to the bottom of the spraying drone 1. A valve feed pipe 5 is fixedly connected to the bottom of the medicine tank 4. An elastic guide pipe 6 is movably connected to the bottom of the valve feed pipe 5. The elastic guide pipe 6 is located at the top of the feed inlet 24.

[0039] Specifically, such as Figure 2 As shown, the spraying drone 1 has landing gear 7 movably connected to both sides, and the landing gear 7 is located on the outside of the elastic contact pad 25b.

[0040] In this embodiment: the valve feed pipe 5 can replenish the medicine tank 4 and prevent the medicine from leaking; the elastic guide pipe 6 can facilitate quick docking with the automatic docking structure on the top of the medicine storage tank 22; the landing gear 7 allows the auxiliary positioning mechanism 3 and the positioning component 25 to act directly on the landing gear 7 instead of the spraying drone 1, thus avoiding damage to the spraying drone 1.

[0041] Working principle: When the spraying drone 1 is used for pest and disease control, it sprays pesticides in the field and other planting environments. During its flight, when the pesticide tank 4 at the bottom of the spraying drone 1 is nearly depleted, the spraying drone 1 can be guided to multiple replenishment points set up around the field and other planting environments for replenishment. These replenishment points consist of a support frame, a drone landing pad 23, and a pesticide storage tank 22. After being guided to the drone landing pad 23 at the top of the support frame, the spraying drone 1 lands and docks on the drone landing pad 23. However, because the spraying drone 1 cannot be precisely positioned at the top of the replenishment port 24, it is necessary to first rotate the electric turntable 25e to drive the pulling arm 25f to extend the rotation of the electric turntable 25e, which in turn pulls the two connecting rods 25c inward at the same time, and drives the positioning rod 25a inward at the same time. At this time, the elastic contact pad 25b will contact the landing gear 7 at the bottom of the spraying drone 1 and gently pull it inward. The drone is slowly pushed inwards and stops when it can no longer move, maintaining a certain travel distance to form a limiting guide rail. Then, the ranging sensor 35 on the inner side of the outermost extension of the nested telescopic positioning beams 31 on both sides judges the final distance of the positioning rod 25a and drives the second electric bidirectional threaded rod 34 to pull the nested telescopic positioning beams 31 to extend or shorten to adapt to different distances of the positioning rod 25a limiting position of the spraying drone 1. After adjustment, the first electric bidirectional threaded rod 33 drives the nested telescopic positioning beams 31 on both sides to move inwards simultaneously, pushing the spraying drone 1 close to the center of the drone landing pad 23, and finally assisting in positioning it directly above the feeding port 24. Then, the quick connector or automatic connector structure on the inner side of the storage tank 22 is used to connect and feed the elastic guide tube 6 at the bottom of the spraying drone 1. After feeding is completed, the positioning of the spraying drone 1 is released, and the next round of prevention and control operation begins.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
