Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment technology, specifically an agricultural weeding device for agricultural facilities. Background Technology

[0002] Traditional weeding methods mainly rely on rotary tillers, pesticides, or manual weeding. Rotary tillers are fast, but they cannot be used in fields that have already been sown or have crops. Pesticide weeding requires spraying with liquid pesticides by drones or manually, which has problems such as high cost of pesticides, pesticide residues on crops, and weed resistance after being killed by pesticides. Manual weeding is time-consuming and labor-intensive, but it can achieve higher precision. Each of these three methods has its advantages and disadvantages. In today's technological context, using drones for weeding is more efficient, and drones that integrate big data and AI recognition can achieve even greater precision when weeding.

[0003] Existing drones have relatively short loiter times, and their propellers are prone to colliding with crop leaves, causing drone crashes or crop damage. Therefore, there is a need for unmanned equipment with long loiter times, precise operation capabilities, and diverse functions to participate in agricultural weeding operations.

[0004] An investigation revealed a Chinese utility model patent (publication number: CN207783570U) disclosing a drone-based lawnmower. The drone includes a main body with landing gear fixedly connected to both sides of its bottom. A fixed box is fixedly connected to the center of both sides of the drone's bottom. A sliding opening is provided on the side of the fixed box near the landing gear. A first sprocket is rotatably connected to the upper part of the inner wall of the fixed box, and a second sprocket is rotatably connected to the lower part of the inner wall. The first and second sprockets are connected by a chain rope fitted around their outer sides. This utility model, through the combined use of an electric telescopic rod, a fixed rod, a chain rope, and a connecting rod, can change the height of the cutting blade to mow the lawn. Due to the gravity of the sleeve and the electric telescopic rod, when the drone lands, adjusting the length of the electric telescopic rod shortens it, preventing the cutting blade from contacting the ground and causing damage. It is highly practical and worthy of widespread promotion.

[0005] Existing technology uses a combination of electric telescopic poles, fixed poles, chains, and connecting poles to change the height of the cutting blades for lawn mowing. However, it has limited functionality, short hang time, and cannot collect and analyze terrain and crop data in real time, making it unable to automatically analyze the location where work needs to be done.

[0006] Therefore, this utility model provides an agricultural weeding device for agricultural facilities to solve the above problems. Utility Model Content

[0011] The loitering system and flight control system do not generate strong airflow towards the crop. The loitering power of the loitering system does not completely depend on the flight control system, and the flight control system operates intermittently.

[0012] As a preferred technical solution of this application, a side bracket is fixedly connected to the extended frame, a servo control arm is fixedly connected to the side bracket, and an outward acquisition lens and an inward acquisition lens are fixedly connected to the servo control arm, with a certain number of outward acquisition lenses and inward acquisition lenses.

[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] This utility model provides an agricultural weeding device for agricultural facilities, such as... Figures 1-6 As shown, it includes a loitering system 1, an extension frame 2 fixedly connected to the loitering system 1; a liquid spraying system 3 fixedly connected to the extension frame 2; and a flight control system 4 fixedly connected to the extension frame 2.

[0028] The loitering system 1 and flight control system 4 do not generate strong airflow towards the crops. The loitering power of the loitering system 1 does not completely depend on the flight control system 4, and the flight control system 4 operates intermittently. A side support 5 is fixedly connected to the extended frame 2. A servo control arm 51 is fixedly connected to the side support 5. An outward-facing acquisition lens 52 and an inward-facing acquisition lens 53 are fixedly connected to the servo control arm 51. There are several outward-facing acquisition lenses 52 and inward-facing acquisition lenses 53.

[0029] The number of outward-facing acquisition lenses 52 and inward-facing acquisition lenses 53 is equal. The outward-facing acquisition lenses 52 face the outer area of ​​the side bracket 5, and the inward-facing acquisition lenses 53 face the lower area of ​​the extension bracket. Both the outward-facing acquisition lenses 52 and the inward-facing acquisition lenses 53 are movable.

[0030] An extension base plate 54 is fixedly connected to the extension bracket, a robotic arm 55 is fixedly connected to the extension base plate 54, a working extension end 56 is rotatably connected to the end of the robotic arm 55, and a cutting blade 57 is fixedly connected to the working extension end 56.

[0031] The spacing between the robotic arms 55 can be adjusted according to the actual spacing of the field, and the working extension end 56 can rotate and extend.

[0032] The cutting blade 57 is detachable, and the working extension end 56 can be connected to other working devices.

[0033] Specifically, the hovering system 1 consists of two layers of balloons, one inner and one outer. These balloons are inelastic and can be filled with helium or hydrogen to provide buoyancy. The control method is to control the buoyancy of the balloons by the pressure difference between the inner and outer layers. The hovering system 1 relies on static buoyancy or a combination of both, resulting in energy consumption far lower than that of multi-rotor drones. It can achieve continuous hovering operations for several hours to several days, completely overcoming the bottleneck of short endurance of traditional drones. The hovering system 1, the extended frame 2, the liquid spraying system 3, and the flight control system 4 together form a support platform, which is used to support the basic liquid spraying function and to install the side supports 5 and the robotic arm 55. Under the control of the servo control arm 51, the outward-facing acquisition lens 52 and the inward-facing acquisition lens 53 acquire and identify images in real time directly below the extended frame 2 and diagonally below the side support 5. The images are labeled using big data and AI, and then the multi-degree-of-freedom robotic arm 55 is controlled to perform the operation. The operation extension end 56 can integrate precision nozzles, sensors or sampling tools to achieve precise treatment, sampling or diagnosis of specific plants, fruit trees or hard-to-reach areas. At the same time, after the cutting blade 57 is removed, the operation extension end 56 can be extended to mount pollination devices, seed spreaders, physical control devices, etc., making it a multi-purpose machine that can be configured as needed. Users can quickly change the load according to the current task requirements, such as large-area spraying, local fine spraying, disease and pest diagnosis, growth monitoring, etc., which greatly improves the utilization rate and economy of the equipment.

[0034] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
