Description

Technical Field

[0001] This utility model belongs to the field of pest technology, specifically relating to a survey and collection device for crop pests. Background Technology

[0002] In agricultural production, pests and diseases are one of the important factors affecting crop yield and quality. In order to scientifically guide prevention and control work and timely and accurately grasp the types, quantities, occurrence periods and distribution range of pests in the field, it is necessary to carry out systematic pest surveys and monitoring.

[0003] Traditional pest survey methods mainly rely on manual field inspections and visual counting, which are not only time-consuming and labor-intensive, but also greatly affected by the experience of the surveyors. They are difficult to achieve continuous, dynamic, and large-scale monitoring, and the data representativeness is poor, which cannot meet the needs of precision plant protection in modern agriculture.

[0004] In recent years, various insect trapping devices have been widely used for the monitoring and control of agricultural pests. Common traps mainly include sex pheromone traps, yellow / blue sticky traps, and black light traps. These devices have improved the efficiency of pest surveys to some extent. However, many traditional traps lack effective escape prevention structures. After being attracted, pests may fly out or crawl out again due to environmental changes or their own activities, resulting in inaccurate capture numbers and affecting the reliability of survey data. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for investigating and collecting crop pests.

[0006] To achieve the above objectives, this utility model provides a survey and collection device for crop pests, including a threaded cover plate and a collection bucket. A through groove is provided at the center of the cover plate. First grids are equidistantly installed on the cover plate along the circumferential direction. A trapping unit is provided on the cover plate between adjacent first grids. An annular block is rotatably installed on the cover plate outside the through groove. A flow port is provided on the annular block. A partition is fixedly installed on the annular block. A second grid is fixedly installed on the side of the partition near the cover plate. The device also includes a cover body with an entry hole. A motor is installed on the inner wall of the cover body. The output end of the motor is fixed to the annular block through a reducer.

[0007] In the above technical solution, a first check valve is further fixedly installed inside the flow port.

[0008] In the above technical solution, a second check valve is further fixedly installed inside the inlet hole.

[0009] In the above technical solution, further, slots are provided on both sides of the opening end of the collection bucket, and support ears are fixedly installed on the collection bucket below the slots. A collection bag is fitted inside the collection bucket, and the pull ropes on both sides of the collection bag pass through the slots and are hung on the support ears.

[0010] In the above technical solution, a solar panel is fixedly installed on the cover, and a storage battery is fixedly installed inside the cover, with the solar panel and the storage battery being electrically connected.

[0011] In the above technical solution, the trapping unit further includes an insect-attracting lamp and a pheromone release slot. The insect-attracting lamp is electrically connected to a storage battery via a wire and is equipped with a control switch.

[0012] In the above technical solution, both the first grille and the second grille are arc-shaped and have the same radius of curvature, and the opening directions of the first grille and the second grille are opposite.

[0013] Furthermore, the above technical solution also includes a shelf with hanging holes.

[0014] In the above technical solution, an information box is further fixedly installed on the side of the shelf near the cover plate.

[0015] In the above technical solution, a locking block is further fixedly installed on the side of the shelf away from the cover plate, a plug rod is slidably installed inside the locking block, and a locking bolt is threaded on the locking block.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting multiple first grids and trapping units on the cover plate, pests are attracted into the device by using light sources or pheromones of specific wavelengths. As the first grid rotates, it gradually intersects with the second grid, and the space between the first grid and the second grid gradually decreases. The pests are driven to the flow outlet and then fall into the collection bucket. The cover plate is unscrewed periodically, and the collected pests are taken out for classification and statistics.

[0017] 2. The trapping unit can be flexibly configured with parameters for the light and pheromone releaser according to the needs of different pest species, which enhances the versatility and adaptability of the device and meets the monitoring needs of various agricultural pests.

[0018] 3. The collection bag's drawstring is threaded from the inside out through the slot and hangs naturally on the support ears. When pests fall in, the bag opening remains open due to the drawstring's suspension, ensuring the pests fall smoothly into the bag. The pests then fall into the collection bag through the through-slot and flow opening in the center of the cover. Because the collection bag is taut and fixed by the drawstring, it will not collapse due to internal accumulation or airflow, always maintaining effective collection space. When replacement or sampling is needed, simply remove the drawstring from the support ears to remove the entire bag of pest samples completely without disassembling the entire device. After removing the old bag, replace it with a new one and re-thread the drawstring and hang the ears for continued use. Attached Figure Description

[0021] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1: like Figures 1-5The device shown is for investigating and collecting crop pests. It includes a threaded cover plate 1 and a collection bucket 2 for easy disassembly, cleaning, and replacement of the internal collection bags. A through groove 101 is provided in the center of the cover plate 1 as the main channel for pests to enter the collection bucket 2. First grids 3 are installed equidistantly along the circumference of the cover plate 1. Trapping units 4 are provided on the cover plate 1 between adjacent first grids 3. An annular block 5 is rotatably installed on the cover plate 1 outside the through groove 101. A flow port 501 is provided on the annular block 5. A partition 6 is fixedly installed on the annular block 5. A second grid 7 is fixedly installed on the side of the partition 6 near the cover plate 1. Both the first grid 3 and the second grid 7 are arc-shaped and have the same radius of curvature. The opening directions of the first grid 3 and the second grid 7 are opposite. It also includes a transparent cover 8 with an entry hole 801 for pests to fly in from the outside. A motor 9 is installed on the inner wall of the cover 8. The output end of the motor 9 is fixed to the annular block 5 through a reducer, driving the annular block 5 to rotate slowly.

[0023] This embodiment provides a survey and collection device for crop pests. The trapping unit 4 emits light of a specific wavelength to attract flying pests. After being attracted by the light source, the pests fly into the device through the entry hole 801 on the side of the cover 8. The annular block 5 rotates slowly under the drive of the motor 9. During the rotation, the first grid 3 gradually intersects with the second grid 7, and the space between the first grid 3 and the second grid 7 gradually decreases. The pests are driven to the flow port 501 and then fall into the collection bucket 2. The cover plate 1 is screwed off periodically to take out the collected pests for classification and statistics.

[0024] Furthermore, a first check net 10 is fixedly installed inside the flow port 501 to prevent pests that have entered the flow port 501 and are about to fall into the collection bucket 2 from returning to the upper space of the device. A second check net 11 is fixedly installed inside the entry hole 801 to prevent non-target organisms or other debris from accidentally entering the device while the pests are attracted into it. It also plays a certain role in preventing escape, ensuring that once the pests enter the device from the outside, they cannot easily escape.

[0025] Reference Figure 3 The collection bucket 2 has slots 201 on both sides of its open end. The slots 201 extend vertically and penetrate the bucket wall. Support ears 202 are fixedly installed on the collection bucket 2 below the slots 201. A collection bag is placed inside the collection bucket 2. The pull ropes on both sides of the collection bag pass through the slots 201 and hang on the support ears 202. When in use, the collection bag is placed into the collection bucket 2 and unfolded. Then, the pull ropes on both sides pass through the corresponding slots 201 from the inside and hang on the support ears 202 below, thereby opening the bag opening and fixing it stably to the open end of the collection bucket 2.

[0026] Place the empty collection bag into the collection bucket 2, and thread the pull rope from the inside out through the slot 201, allowing it to hang naturally on the support ear 202. When pests fall in, the bag opening remains open due to the pull rope's suspension, ensuring the pests fall smoothly into the bag. The pests fall into the collection bag through the through slot 101 and flow opening 501 in the center of the cover plate 1. Because the collection bag is tensioned and fixed by the pull rope, it will not collapse due to internal accumulation or airflow, always maintaining effective collection space. When it is necessary to replace or take samples, simply remove the pull rope from the support ear 202 to remove the entire bag of pest samples completely without disassembling the entire device. After removing the old bag, replace it with a new bag and re-thread the rope and hang the ear for continued use.

[0027] Reference Figure 3 and Figure 5 A solar panel 12 is fixedly installed on the cover 8, and a storage battery 13 is fixedly installed inside the cover 8. The solar panel 12 and the storage battery 13 are electrically connected to form an independent solar charging system.

[0028] The trapping unit 4 includes an insect-attracting lamp 401 and a pheromone release tank 402. The insect-attracting lamp 401 is an LED lamp bead that emits a specific wavelength to attract phototactic pests. The pheromone release tank 402 contains a slow-release insect sex pheromone. The insect-attracting lamp 401 is electrically connected to the storage battery 13 through a wire and is equipped with a control switch for controlling the start and stop of the light.

[0029] During the day, the solar panel 12 converts light energy into electrical energy through a converter to charge and store the battery 13. This is a mature existing technology. The battery 13 provides continuous power for the operation of the trapping unit 4 at night or on cloudy days, enabling the device to be powered autonomously around the clock. At night, the insect-attracting lamp 401 is activated by a control switch. The light radiates outward from inside the cover 8, attracting phototactic flying pests to fly in through the entry hole 801. The pheromone release slot 402 continuously and slowly releases specific chemical signals to attract target pests that are sensitive to the pheromone, achieving precise and targeted trapping. The two trapping methods work together to expand the trapping range and improve the capture rate of pests with different behaviors and habits.

[0030] Example 2: like Figures 1-2 As shown, this embodiment is further optimized based on the first embodiment, and adds a detachable storage component for on-site information recording and device fixed management. It also includes a storage rack 14 with a hanging hole 1401 for hanging.

[0031] Furthermore, an information box 15 is fixedly installed on the side of the shelf 14 near the cover plate 1. The information box 15 is a transparent sealed box, which can hold paper record cards, QR code labels or RFID chips to record information such as survey time, location, responsible person, and crop type.

[0032] A locking block 16 is fixedly installed on the side of the shelf 14 away from the cover plate 1. A plug rod 17 is slidably installed inside the locking block 16. A locking bolt 18 is threaded on the locking block 16.

[0033] When setting up the device in the field, staff fill in the survey information on cards and put them in information box 15, or affix QR code labels. Patrol personnel can quickly obtain electronic files by scanning the QR code to achieve information management. Insert the pole 17 into the field or into the metal or wooden support piles that have been buried in the ground beforehand, and then tighten the locking bolt 18 to firmly lock the pole 17, thereby stabilizing the entire pest collection device in the field and preventing it from tipping over or being lost due to wind, animal contact, or human movement.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
