Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a crop pest and disease detection UAV. Background Technology

[0002] Agriculture is the foundation of the national economy, and crop diseases and pests are one of the main threats to the stability of agricultural production, leading to reduced crop yields or even crop failure, causing huge economic losses. Therefore, timely and effective detection and control of diseases and pests are key to ensuring food security and agricultural development.

[0003] Traditional pest and disease control methods mainly rely on manual backpack sprayers or large ground machinery for pesticide spraying. Manual spraying is not only labor-intensive and inefficient, but also poses health risks to operators who are in direct contact with pesticides for a long time. Although ground machinery is more efficient, it is limited by terrain conditions and is difficult to operate in hills, mountains or paddy fields. In addition, it is easy to compact the soil and damage crops during the process.

[0004] With the rapid development of drone technology, plant protection drones have emerged as a new type of agricultural equipment. By operating from the air, they overcome terrain limitations and avoid damage to crops. With their high efficiency and wide coverage, they have been widely used in the field of pesticide spraying. However, the existing application mode of plant protection drones generally has an inherent defect: the reconnaissance and prevention and control links are separated. Farmers or technicians need to first manually patrol the fields to find the occurrence of pests and diseases. After confirming the location and extent of the disease, they then dispatch plant protection drones to carry out large-scale spraying operations.

[0005] This separation pattern leads to an unavoidable time delay between the discovery of a disease and the implementation of control measures. During this delay, the initial, small-scale pests and diseases have already spread rapidly, missing the optimal window for control, resulting in increased control costs and reduced effectiveness. In addition, the use of large-scale spraying for initial localized diseases also leads to a waste of pesticides.

[0006] Therefore, this utility model proposes a crop pest and disease detection drone to address the shortcomings of existing technologies. Utility Model Content

[0007] In view of the fact that the detection and prevention functions of existing crop pest and disease detection drones are separated, resulting in the inability to deal with pests and diseases immediately after detection and causing delays in prevention and control, this utility model aims to provide a crop pest and disease detection drone with an improved structure that can effectively solve the above problems.

[0008] This utility model provides a crop pest and disease detection drone, including: a hollow shell; and a flight mechanism and a spraying mechanism.

[0009] The spraying mechanism comprises a power transmission and centrifugal spraying assembly consisting of a motor, a worm gear, a worm wheel meshing with the worm gear, and a hollow column driven to rotate by the worm wheel.

[0010] Furthermore, the flight mechanism, the spraying mechanism, and the hollow shell are combined by a fixed connection.

[0011] Preferably, the first power assembly of the flight mechanism includes a support rod, a motor, and two blades, wherein the motor is mounted on the support rod for driving the two blades to rotate.

[0012] Preferably, the first power assembly further includes a rotating rod and a support frame consisting of a first fixed ring, a first support column, and a second fixed ring. The rotating rod rotates within the frame and is connected to the two blades via a fixed block and the second support column.

[0013] Preferably, the second power assembly of the flight mechanism includes a fixed column, a second motor installed in the fixed column, and a three-bladed unit driven to rotate by the second motor.

[0014] Preferably, the spraying mechanism further includes a rotating column, and the motor is connected to the worm gear transmission through the rotating column.

[0015] Preferably, the crop pest and disease detection drone also includes a storage compartment and a transport pipe, wherein the transport pipe is disposed between the storage compartment and the hollow column for transporting pesticide solution.

[0016] Preferably, the spraying mechanism further includes a column cover and a stabilizing ring. The column cover is disposed on the top of the hollow column, and the stabilizing ring is sleeved on the outside of the hollow column to provide support for the high-speed rotating hollow column.

[0017] Preferably, the crop pest and disease detection drone further includes a monitoring shell and a spherical monitor, the monitoring shell being connected to the bottom of the hollow shell for mounting the spherical monitor.

[0018] This utility model has the following beneficial effects:

[0019] 1. This utility model integrates a spherical monitoring system with a spraying mechanism consisting of a motor, worm gear, and centrifugal hollow column onto the hollow shell of a drone. This solves the problem in existing technologies where the detection and control of crop diseases and pests are separated, leading to delays in treatment after the disease or pest is detected. This invention enables real-time detection of crops and immediate initiation of spraying operations upon detection of diseases and pests, achieving "detection and treatment," and greatly improving the timeliness and efficiency of disease and pest control.

[0020] 2. This utility model, by adopting a spraying method in which a worm gear driven by a motor reduces speed and drives a hollow column to rotate at high speed, and uses centrifugal force to fling out the liquid pesticide for atomization, solves the problems of uneven spraying or poor atomization effect that may exist in traditional pressure sprayers. It achieves the technical effect of sufficient liquid pesticide atomization, uniform droplets, more effectively covering the crop surface, and improving pesticide utilization and control effect.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] Example:

[0029] Please refer to Figures 1 to 4 This utility model provides a crop pest and disease detection drone, which aims to solve the problem of the separation of crop pest and disease detection and control in the prior art, resulting in delays in control.

[0030] like Figure 1 and Figure 2 As shown, the crop pest and disease detection drone includes a hollow shell 1, and a flight mechanism and a spraying mechanism 2 fixedly connected to the hollow shell 1. The hollow shell 1 serves as the mounting base and support platform for the entire device. The flight mechanism is used to provide and control the power required for the drone's flight, while the spraying mechanism 2 is used for crop detection and pesticide spraying operations.

[0031] To solve the above-mentioned technical problems, the core of the technical solution of this embodiment lies in the internal power transmission and atomization structure of the spraying mechanism 2, and a specific installation and cooperation relationship is formed between the structure and the hollow shell 1.

[0032] Please refer to the following carefully. Figure 1 , Figure 3 and Figure 4 The core structure will be described in detail below:

[0033] The spraying mechanism 2 includes a motor 201 fixedly connected inside the hollow shell 1. The motor 201 is connected to the worm gear 203 via a rotating column 202. The worm gear 203 meshes with the worm wheel 204 for transmission. The worm wheel 204 is fixedly connected to the upper end of the hollow column 205. The hollow column 205 is used as a centrifugal nozzle. Its function is to use the centrifugal force generated by high-speed rotation to atomize the internal liquid and throw it out evenly.

[0034] Meanwhile, the storage chamber 209 fixed to the hollow shell 1 is connected to the column cover 206 through the transport pipe 208. The column cover 206 is placed on the top of the hollow column 205 and is used to introduce the liquid medicine from the storage chamber 209 into the inner cavity of the hollow column 205. A stabilizing ring 207 is also sleeved on the outside of the hollow column 205 to provide radial support for the high-speed rotating hollow column 205, ensuring the stability and atomization effect of the liquid medicine spraying process.

[0035] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0036] As a preferred embodiment, to provide stable and reliable vertical lift, please refer to... Figure 1 and Figure 2 The flight mechanism includes a first power assembly, which includes a motor 4 mounted on a support rod 3, a rotating rod 8, and two blades 9 connected to the rotating rod 8. To ensure the stability of the rotation process, the first power assembly also includes a fixing ring 5, a support column 6, a second fixing ring 7, a second support column 10, and a fixing block 11. The rotating rod 8 rotates within a frame formed by the fixing ring 5, the support column 6, and the second fixing ring 7. The two blades 9 are fixedly connected to the rotating rod 8 through the fixing block 11 and the second support column 10.

[0037] As another preferred implementation, to achieve horizontal movement of the drone, please refer to... Figure 1 The flight mechanism also includes a second power assembly, which includes a fixed column 12 disposed on the hollow shell 1, a second motor 13 installed inside the fixed column 12, and a three-bladed rotor 14 driven to rotate by the second motor 13.

[0038] As one specific implementation method, please refer to Figure 4 The spraying mechanism 2 also includes a rotating column 202, the output shaft of the motor 201 is fixedly connected to the rotating column 202, and the other end of the rotating column 202 is fixedly connected to the worm gear 203.

[0039] As another preferred embodiment, in order to construct a complete liquid delivery path and stabilize the spray head, please refer to... Figure 1 and Figure 3 The drone also includes a storage compartment 209, a transport pipe 208, a column cover 206, and a stabilizing ring 207. The storage compartment 209 is connected to the column cover 206 through the transport pipe 208. The column cover 206 is placed on top of the hollow column 205, and the stabilizing ring 207 is fitted on the outside of the hollow column 205.

[0040] As another preferred implementation method, in order to achieve real-time crop monitoring, please refer to... Figure 1 The drone also includes a monitoring shell 210 and a spherical monitor 211. The monitoring shell 210 is fixedly connected to the bottom of the hollow shell 1, and the spherical monitor 211 is installed inside the monitoring shell 210.

[0041] Working principle: When the drone is started, the hollow shell 1 supports the support rod 3. The motor 4 starts and drives the rotating rod 8 to rotate, causing the two blades 9 to rotate at high speed. The drone rises. The fixed ring 5 and the support column 6 ensure the rotational stability within the fixed ring 7. The fixed block 11 and the support column 10 ensure the rotational safety of the two blades 9. The motor 13 starts within the fixed column 12 and drives the three blades 14 to rotate, completing horizontal movement at a certain height. This achieves constant-speed horizontal movement and avoids feature deformation caused by random changes in the lens angle.

[0042] After takeoff, the drone observes the crop through the spherical monitor 211 fixed in the monitoring shell 210. If a problem is detected, the spraying mechanism 2 can start the motor 3 201 to drive the rotating column 202 to rotate, which in turn drives the worm gear 203 and worm wheel 204 to mesh and rotate, causing the hollow column 205 to rotate. The pesticide enters the hollow column 205 through the storage chamber 209 and the transport pipe 208 to the column cover 206. After being stabilized at high speed by the rotating stabilizing ring 207, the pesticide is evenly sprayed on the crop, realizing immediate treatment upon detection, minimizing the damage caused by pests and diseases, and avoiding the situation where a small problem becomes a big disaster due to delayed prevention and control.
