Description

Technical Field

[0001] This invention relates to the field of agricultural production technology, specifically to an agricultural pest monitoring device. Background Technology

[0002] Currently, the monitoring and management of crop growth in most parts of my country mainly includes soil irrigation, pesticide spraying, soil fertilization, and agricultural pest monitoring. With the continuous development of science and technology, the concept of smart agriculture and corresponding automatic crop monitoring devices have gradually gained attention and are being used. Especially for crops planted on a large scale, automatic crop monitoring devices can greatly reduce the workload and labor intensity of planting personnel.

[0003] There are two main types of monitoring devices currently used for agricultural pest monitoring: those using high-voltage electric grids for early-stage pest collection and those using sticky insecticides. While these devices can achieve their intended purpose, they have several significant drawbacks. High-voltage electric grids, used primarily for early-stage pest collection, pose a significant safety hazard as they can be dangerous to operators and unsuspecting individuals. Furthermore, the high-voltage current can directly carbonize some pests during the killing process, hindering the subsequent image recognition and counting system from quickly and effectively identifying them, greatly reducing the accuracy and reliability of the data. As for sticky insecticides, the insecticides dry out significantly during prolonged exposure to the elements, resulting in a substantial decrease in stickiness. Moreover, many current sticky insecticides are made from environmentally unfriendly chemical concoctions, which can negatively impact both crops and users.

[0004] Therefore, it is of great importance to design an agricultural pest monitoring device to solve the above problems. Summary of the Invention

[0016] Beneficial effects

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This invention utilizes a specially designed insect-attracting mechanism. When capturing pests, an insect attractant is added to the attractant box. The attractant evaporates into the surrounding environment, attracting pests into the insect-collecting funnel. The insects are then transported through the funnel to the insect-attracting box, where they are placed between a fixed plate and a moving plate. A moving component then drives the moving plate towards the fixed plate, bringing them into contact and compressing the pests to form specimen-like structures. A camera captures images of the pests, which are then wirelessly transmitted to a control terminal. A deep learning-based database analyzes, identifies, counts, and maps the images, ultimately providing feedback to staff who are fully aware of the types and numbers of pests affecting their crops. This allows for targeted planting plans. Compared to existing monitoring devices that primarily use high-voltage electric grids for pest capture, this method minimizes damage to the pests and improves the effectiveness and accuracy of subsequent image recognition.

[0019] 2. This invention, through the setting of an outlet, opening and closing door, cleaning component, and linkage component, after the pests are photographed between the moving plate and the fixed plate, the moving component resets the moving plate. At this time, the electric push rod pushes the push plate towards the outlet. The brushes on both sides of the push plate clean the pests adhering to the fixed plate and the moving plate. In the passageway of the push plate, the opening and closing door is opened synchronously by the wire rope, thereby cleaning the pests out of the outlet. This allows the equipment to automatically clean and has the function of repeatedly collecting data and monitoring for a long time.

[0020] 3. This invention, through its fertilization mechanism, allows workers to prepare fertilizer based on collected pest information. The fertilizer is then placed into a fertilizer tank, stirred and mixed evenly by a stirrer, and then transported to a spray pipe via a drainage pump. The fertilizer is then sprayed onto the crops through a spray head. A height adjustment component is used to adjust the height of the spray pipe, facilitating the application of fertilizer to the crops and achieving automated fertilization, thus saving manpower.
