Description

Technical Field

[0001] This invention discloses a forest pest monitoring and forecasting device, belonging to the technical field of forest pest control equipment. Background Technology

[0002] With the development of modern technology, numerous insect monitoring products have emerged for various industries, resulting in a wide variety of products on the market. These products employ diverse monitoring methods, but most rely on single-point deployment, are large and expensive, and collect a mixed range of insects. Currently, most insect monitoring products depend on placing insect-attracting mechanisms inside a box to lure and kill insects. After the insects die, they gather on a specific placement device, and a camera is used to photograph them. Data analysis is then used to calculate the insect population and complete the insect infestation report. However, because existing insect monitoring products use a single box to attract one or a few types of insects with similar habits, the varying attractiveness of different attracting mechanisms can affect the infestation report results, leading to ambiguity in the accuracy of the data. Furthermore, each monitoring session yields only a single result, making it impossible to simultaneously monitor multiple insect species. Summary of the Invention

[0003] The purpose of this invention is to solve the problems in the prior art and to provide a forest pest monitoring and forecasting device.

[0004] This invention achieves the above-mentioned objective through the following technical solution: a forest pest monitoring device, comprising an installation cylinder and an insect-attracting mechanism. At least three insect-attracting mechanisms are symmetrically arranged around the axis of the installation cylinder, and each mechanism includes an insect-attracting element, a movable cylinder, and a fixed cylinder. The fixed cylinder is fixedly installed inside the installation cylinder. The installation cylinder has a positioning protrusion embedded in the movable cylinder. The lower end of the movable cylinder is rotatably installed inside the fixed cylinder. The insect-attracting element is located inside the movable cylinder, and one end is detachably mounted on the positioning protrusion. The installation cylinder has a circular protrusion that mates with the outer wall of the movable cylinder. Both the protrusion and the movable cylinder are provided with an inlet centered on the axis of the movable cylinder and having a certain central angle. The mounting cylinder is provided with a transmission component for driving the movable cylinder to rotate, so that the protrusion and the inlet on the movable cylinder can be aligned or misaligned when the movable cylinder rotates. The mounting cylinder is rotatably provided with a receiving tray at the lower end corresponding to the fixed cylinder, and there is a camera mechanism for photographing insects between two adjacent insect-attracting mechanisms. The mounting cylinder is also provided with a power component for driving the receiving tray to switch positions below the camera mechanism and the fixed cylinder. The receiving plate and the mounting cylinder are provided with a cleaning mechanism.

[0005] Preferably, the insect-attracting mechanism has four parts arranged symmetrically at 90°, the fixed cylinder has an annular protrusion in the middle, the mounting cylinder has a support platform inside, and the annular protrusion is fixed to the support platform by bolts.

[0006] Preferably, the mounting cylinder includes a cover plate, a first cylinder, a second cylinder, and a third cylinder that are fixed by bolts. The positioning boss is located on the cover plate. The first cylinder and the second cylinder are provided with mounting parts for mounting transmission components. The support platform is located on the second cylinder.

[0007] Preferably, the transmission component includes a first motor, a driving gear, a gear ring, and a driven gear. The driven gear is fixed to the outside of the movable cylinder, the gear ring is located outside the driven gear, and a positioning ring rotatably connected to the second cylinder is provided on the gear ring. The first motor is mounted on the mounting part, and its output shaft is fixedly connected to the driving gear. The gear ring is provided with an array of external tooth blocks and internal tooth blocks. The external tooth blocks mesh with the driving gear for transmission, and the internal tooth blocks mesh with the driven gear for transmission.

[0008] Preferably, the power component includes a second motor, a drive disk, and a grooved wheel. The grooved wheel has eight arrayed grooves, and there is an arc-shaped notch between two adjacent grooves. The drive disk has a notched boss at its center that mates with the arc-shaped notch. A push rod is provided on one side of the notched boss that is eccentrically positioned with respect to the center of the drive disk. The push rod slides in conjunction with the grooves. The second motor is mounted on a support platform, and its output shaft is fixedly connected to the drive disk. A connecting rod is provided at the center of the grooved wheel. One end of the connecting rod is rotatably connected to the support platform, and the other end is fixedly connected to the receiving tray.

[0009] Preferably, the cleaning mechanism includes a first discharge port, a second discharge port, and cleaning brushes. There are four of each of the first and second discharge ports. The first discharge port is located on the receiving tray, and the second discharge port is located on the third cylinder. When the receiving tray is installed inside the mounting cylinder, the first and second discharge ports are arranged vertically, and the first discharge port is located between the projection of the camera mechanism and the fixed cylinder on the horizontal plane. There are four cleaning brushes, and one end of each brush is provided with a mounting ring that is fixedly connected to the third cylinder.

[0010] Preferably, a disperser is provided at the lower end of the fixed cylinder. The disperser includes a sleeve and a spiral guide plate. Multiple spiral guide plates are arranged in an array around the axis of the sleeve, and multiple dispersion ports are arranged on the spiral guide plate at equal heights. The sleeve is welded to the spiral guide plate, and the sleeve is fixedly connected to the fixed sleeve by a pin.

[0012] Preferably, the insect-attracting device is an insect-attracting lamp or an insect-attracting release device containing chemical agents.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. By setting up an installation cylinder, insect-attracting mechanism, camera mechanism, power unit, and receiving tray, insects are attracted by the insect-attracting device and enter the movable cylinder through the inlet. After the insects die, they fall down the bottom of the fixed cylinder into the receiving tray. The power unit drives the receiving tray to rotate, allowing the insects to move into the shooting range of the camera mechanism. Insect pest monitoring and reporting can be completed by taking pictures and analyzing the insects. Moreover, multiple insect-attracting mechanisms can be used to monitor and report insect pests of different types of insects, or to test the attractiveness of different insect-attracting devices to a single insect. This can more accurately reflect the results of insect pest monitoring and reporting, and the coverage of monitoring and reporting is wider.

[0015] 2. By setting up a transmission component and a cleaning mechanism, the transmission component can drive the movable cylinder to rotate at a certain angle, so that the movable cylinder and the inlet on the round protrusion are misaligned. When it rains, it can effectively prevent rainwater from entering the movable cylinder and affecting the insect monitoring work. It can also prevent insects from flying out of the movable cylinder to a certain extent. The cleaning mechanism can clean the insects on the receiving tray from the first and second discharge ports and remove them from the installation cylinder, thereby achieving an automatic cleaning effect and enabling repeated insect monitoring work without manual cleaning.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1

[0029] like Figures 1-10As shown, a forest pest monitoring device includes an installation cylinder 5 and an insect-attracting mechanism 4. At least three insect-attracting mechanisms 4 are symmetrically arranged around the axis of the installation cylinder 5. Each insect-attracting mechanism 4 includes an insect-attracting element 10, a movable cylinder 11, and a fixed cylinder 12. The fixed cylinder 12 is fixedly installed inside the installation cylinder 5. The installation cylinder 5 has a positioning boss 9 embedded in the movable cylinder 11. The lower end of the movable cylinder 11 is rotatably installed inside the fixed cylinder 12. The insect-attracting element 10 is located inside the movable cylinder 11, and one end is detachably mounted on the positioning boss 9. The installation cylinder 5 has a round protrusion 2 that mates with the outer wall of the movable cylinder 11. Both the round protrusion 2 and the movable cylinder 11 are provided with... The installation cylinder 5 has an inlet 7 centered on the axis of the movable cylinder 11 and with a certain central angle. The installation cylinder 5 is equipped with a transmission component 3 for driving the movable cylinder 11 to rotate, so that when the movable cylinder 11 rotates, the round protrusion 2 can be aligned with or misaligned with the inlet 7 on the movable cylinder 11. The installation cylinder 5 is rotatably equipped with a receiving plate 15 corresponding to the lower end of the fixed cylinder 12. The installation cylinder 5 is equipped with a camera mechanism 34 for shooting insects between two adjacent insect-attracting mechanisms 4. The installation cylinder 5 is also equipped with a power component 14 for driving the receiving plate 15 to switch positions below the camera mechanism 34 and the fixed cylinder 12. The receiving plate and the installation cylinder 5 are equipped with a cleaning mechanism 35.

[0030] like Figure 1 , Figure 2 and Figure 4 As shown, four insect-attracting mechanisms 4 are symmetrically arranged at 90°. A ring protrusion 26 is provided in the middle of the fixed cylinder 12. A support platform 16 is provided inside the mounting cylinder 5. The ring protrusion 26 is fixed to the support platform 16 by bolts. The four insect-attracting components 10 are insect-attracting lamps of different colors that attract the same type of insect or insect-attracting release components with different chemical agents. In this way, the attractiveness of different insect-attracting lamps or insect-attracting release components to the same type of insect can be tested. The monitoring and reporting work of the four insect-attracting components 10 will not affect each other, thus obtaining more accurate insect monitoring and reporting results. The ring protrusion 26 can easily fix the fixed cylinder 12 to the inside of the mounting cylinder 5, so that the movable cylinder 11 can be effectively supported.

[0031] like Figure 1 and Figure 3 As shown, the mounting cylinder 5 includes a cover plate 17, a first cylinder 18, a second cylinder 19, and a third cylinder 20, which are fixed by bolts. The positioning boss 9 is located on the cover plate 17. The first cylinder 18 and the second cylinder 19 are provided with mounting parts 6 for mounting the transmission component 3. The support platform 16 is located on the second cylinder 19. The mounting cylinder 5 is designed as a split assembly structure, which can facilitate the installation of the insect-attracting mechanism 4 and the transmission component 3. The overall structure is simple and easy to disassemble and assemble.

[0032] like Figure 1 , Figure 2 and Figure 4 As shown, the transmission component 3 includes a first motor 21, a driving gear 22, a gear ring 23, and a driven gear 27. The driven gear 27 is fixed to the outside of the movable cylinder 11. The gear ring 23 is located outside the driven gear 27, and a positioning ring 24 rotatably connected to the second cylinder 19 is provided on the gear ring 23. The first motor 21 is mounted on the mounting part 6, and its output shaft is fixedly connected to the driving gear 22. The gear ring 23 is provided with an array of outer toothed blocks 28 and inner toothed blocks 29. The outer toothed blocks 28 mesh with the driving gear 22 for transmission. The internal toothed block 29 meshes with the driven gear 27 for transmission. The first motor 21 can drive the driving gear 22 to rotate. The external toothed block 28 causes the gear ring 23 to rotate around the center of the positioning ring 24. The internal toothed block 29 drives the driven gear 27 to rotate, causing the movable cylinder 11 to rotate synchronously. This allows the movable cylinder 11 and the inlet 7 on the round protrusion 2 to be in a state of overlap or misalignment, which facilitates the entry of insects into the movable cylinder 11 for insect monitoring and reporting. Alternatively, the movable cylinder 11 can be sealed to achieve a rainproof effect.

[0033] like Figure 2 and Figure 9 As shown, the power component 14 includes a second motor 25, a drive disk 36, and a Geneva wheel 38. The Geneva wheel 38 has eight arrayed grooves 44, and there is an arc-shaped notch 45 between adjacent grooves 44. The drive disk 36 has a notched boss 43 at its center that mates with the arc-shaped notch 45. A push rod 42 is eccentrically positioned on one side of the notched boss 43 and slides in cooperation with the grooves 44. The second motor 25 is mounted on the support platform 16, and its output shaft is fixedly connected to the drive disk 36. A connecting rod 41 is located at the center of the Geneva wheel 38, and one end of the connecting rod 41... One end is rotatably connected to the support platform 16, and the other end is fixedly connected to the receiving tray 15. The second motor 25 drives the drive disk 36 to rotate. When the notched protrusion 43 is engaged with the arc-shaped notch 45, the push rod 42 does not slide into the groove 44. At this time, the groove wheel 38 and the receiving tray 15 remain stationary. When the notched protrusion 43 is separated from the arc-shaped notch 45, the push rod 42 slides into the groove 44 under the drive of the drive disk 36, and can drive the groove wheel 38 to rotate 45°, so that the receiving tray 15 will rotate the insects falling from the fixed cylinder 12 to the area below the camera mechanism 34 for taking pictures and videos, in preparation for counting the number of insects.

[0034] like Figure 8 and Figure 10As shown, the cleaning mechanism 35 includes a first discharge port 40, a second discharge port 46, and cleaning brushes 39. Four of each type of discharge port are provided. The first discharge port 40 is located on the receiving tray 15, and the second discharge port 46 is located on the third cylinder 20. When the receiving tray 15 is installed inside the mounting cylinder 5, the first and second discharge ports 40 and 46 are arranged vertically, with the first discharge port 40 positioned between the projection of the camera mechanism 34 and the fixed cylinder 12 onto the horizontal plane. Four cleaning brushes 39 are provided, and one end of each brush has a mounting ring 37 fixedly connected to the third cylinder 20. After the insects die, they fall from the lower end of the fixed cylinder 12 onto the receiving tray. On the tray 15, the insects are scattered in a circular area. When the power unit 14 drives the receiving tray 15 to rotate, the insects first rotate 45° and then are located below the camera mechanism 34. After the insect monitoring work is completed, when the power unit 14 drives the receiving tray 15 to rotate 45° again, the insects rotate synchronously with the receiving tray 15. When they are blocked by the cleaning brush 39 and remain stationary, the insects can fall from the first discharge port 40 into the second discharge port 46 and be cleaned to the outside of the mounting cylinder 5 when the first discharge port 40 rotates with the receiving tray 15. This achieves an automatic cleaning effect, thereby keeping the receiving tray 15 clean and not affecting the next insect monitoring work.

[0035] like Figure 2 and Figure 5 As shown, a disperser 13 is provided at the lower end of the fixed cylinder 12. The disperser 13 includes a sleeve 31 and a spiral guide plate 32. Multiple spiral guide plates 32 are arranged in an array around the axis of the sleeve 31, and multiple dispersing ports 30 are arranged on the spiral guide plates 32 at equal heights. The sleeve 31 is welded to the spiral guide plate 32, and the sleeve 31 is fixedly connected to the fixed sleeve 31 by a pin 33. When an insect enters the movable cylinder 11 and dies, it falls down the fixed cylinder 12 into the sleeve 31. Since the sleeve 31 has a spiral guide plate 32, the insect falls onto the spiral guide plate 32. Because its surface is an arc structure, the insect will slide along the surface and fall onto the adjacent spiral guide plate 32 when it passes through the dispersing port 30. Multiple spiral guide plates 32 can disperse the insect, so that the insects maintain a certain degree of dispersion uniformity when they fall onto the receiving tray 15, avoiding the concentration of insects and affecting the data statistics.

[0036] like Figure 2As shown, a solar panel 1 is installed on the cover plate 17. The inner solar panel is electrically connected to the first motor 21, the second motor 25, and the camera mechanism 34. A wire tube 8 is provided on the cover plate 17, which passes through the support platform 16. The solar panel 1 automatically stores electrical energy by relying on solar energy and supplies power to the first motor 21, the second motor 25, and the camera mechanism 34. This eliminates the dependence on wiring, making it convenient to install in any sunny location in the forest. The wire tube 8 can guide the wires connecting the solar panel 1 and the second motor 25 into the second cylinder 19, preventing damage to the driven gear 27 during rotation.

[0037] Working principle: When monitoring insect populations, the installation cylinder 5 is fixedly installed at a certain location in the forest. The first motor 21 drives the drive gear 22 to rotate, keeping the movable cylinder 11 and the inlet 7 on the round protrusion 2 aligned. Insects are attracted by the insect attractant 10 and enter the movable cylinder 11. After the insects die, they flow down the fixed cylinder 12 into the disperser 13. The spiral guide plate 32 in the disperser 13 can disperse the insects to a certain extent, ensuring they fall evenly onto the receiving tray 15, avoiding concentrated overlap that would affect the count. The lower end of the disperser 13 is aligned with the receiving tray. The receiving tray 15 has a certain gap. Then, the power component 14 drives the receiving tray 15 to rotate 45°, so that the insects rotate from below the disperser 13 to below the camera mechanism 34 and complete the photo and video recording. The data processing center counts the number of insects. Then, the power component 14 drives the receiving tray 15 to continue rotating 45°. The cleaning brush 39 can block the insects, so that they enter the second discharge port 46 of the third cylinder 20 from the first discharge port 40 on the rear side of the rotation direction of the receiving tray 15, and clean the insects to the outside of the installation cylinder 5, thereby ensuring the cleanliness of the surface of the receiving tray 15 and preparing for the next insect monitoring and reporting work.

[0038] Example 2

[0039] The difference between this embodiment and embodiment 1 is that in this embodiment, the insect attractant 10 can be an insect attractant lamp that attracts different kinds of insects or an insect attractant release device with chemical reagents. In this way, insect monitoring and reporting can be carried out on different kinds of insects, making the monitoring and reporting results more comprehensive.

[0040] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0041] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
