When used in conjunction with electric insecticide nets or pesticides, they can attract insects and effectively kill them, reduce the pest index, and prevent and control insect pests and insect-borne diseases. They are mainly used to kill pests on field crops to reduce the use of pesticides.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The present invention uses a specially structured insecticidal mechanism, a light emission collimator, a light reflector, and multiple insecticidal devices to form a mesh insecticidal section with multiple beams of light interlaced with each other. This mesh insecticidal section can cover pests near crop leaves, not only achieving excellent insecticidal effects but also significantly reducing the probability of pests flying away from the crops.

[0019] The present invention adopts a foldable design structure with three support rods. The unfolding angle is adjusted by the first hinge to adapt to complex terrains such as slopes and ridges. The support base can be unfolded into a triangular stable structure. The support base can stand stably between ridges to avoid the displacement of the insect attractant lamp due to tilting; the height of the support ring is adjusted in real time by the balance component to ensure the vertical accuracy of the main tube, which can cope with the soft soil or slope scenes in the corn field after rain and avoid equipment damage caused by the lamp pole falling; the insect attractant lamp in each space can be adjusted separately to maximize the insecticidal effect of the insect attractant lamp.

DETAILED DESCRIPTION

[0038] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention, combined with the accompanying drawings. Obviously, the described embodiments represent only a portion of the embodiments of the present invention, and not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. The term "based on the embodiments" includes both the corresponding textual description and the accompanying drawings. It should be noted that, to facilitate depiction of the insect trap 14 and other components, the electric insecticide net is not shown in the drawings (the electric insecticide net has been omitted).

[0039] Example 1, as Figures 1 to 6 as well as Figure 16 As shown, a crop growth-tracking, automatically adjustable insecticidal device includes a main tube 10 and a support base 11. An infrared sensor or ultrasonic sensor is mounted on the main tube 10 to monitor crop height in real time (this monitoring technology is conventional). The main tube 10 is mounted on the support base 11, which is also provided with a balancing assembly 15 for maintaining the balance of the main tube 10. A drive assembly, mounted on the support base 11, is connected to the main tube 10 and controls the raising and lowering of the main tube 10. In this example, the drive assembly includes a drive motor 24. A lead screw shaft 241 connected to the output end of the drive motor 24 is connected to the main tube 10. When the drive motor 24 is in operation, it drives the lead screw shaft 241 up and down, thereby driving the main tube 10 up and down. An insecticidal mechanism 13 is mounted on the main tube 10. The insecticidal mechanism 13 includes an insect trap 14 and an electric insecticidal net. The insecticidal lamp 14, the electric insecticidal net, and their insecticidal principles are conventional. The electric insecticidal net typically uses a high-voltage wire mesh (similar to the wire mesh of a mosquito swatter) and is generally arranged around the insecticidal lamp 14. An adjusting mechanism 12 is fixedly installed at the bottom of the main tube 10 . The adjusting mechanism 12 is arranged above the supporting base 11 , and the adjusting mechanism 12 and the supporting base 11 form a lifting mechanism for lifting the main tube 10 .

[0040] The adjustment mechanism 12 cooperates with the first trapezoidal block 25 of the support base 11 to form a multi-level height lock. The insecticide mechanism 13 deploys as the main tube 10 rises, and the insect traps 14 are arranged in layers to effectively kill pests at different heights of the crop. In this embodiment, the infrared sensor or ultrasonic sensor and the drive motor 24 are connected to a controller. During the insecticide process, the infrared sensor or ultrasonic sensor is above the top of the crop (such as a corn stalk), and the sensor does not sense the crop during this process. As the crop grows, the drive motor 24 is activated to raise the main tube 10 to the set height each time the crop reaches a height that is detected by the sensor. At this point, the sensor remains above the top of the crop. This repetitive cycle achieves automatic adjustment to track crop growth.

[0041] In this embodiment, a photovoltaic panel 101 is mounted on the top of the main tube 10. An inverter 102 and a battery 103 are fixedly mounted on the bottom of the photovoltaic panel 101. The photovoltaic panel 101 is placed on a fixing ring 104, which is fixed to the inner wall of the main tube 10. Specifically, after the photovoltaic panel 101 generates electricity, the current and voltage are processed by the inverter 102, and then stored in the battery 103. The battery 103 powers the controller and drive motor 24. Photovoltaic power generation technology is existing technology, and its principles are not further described.

[0042] In this embodiment, the support base 11 includes a support rod 20, a first hinge 21 and a circular base 22; there are three support rods 20, which are evenly arranged at the bottom of the circular base 22 and are rotatably mounted on the circular base 22 through the first hinge 21 to support the entire device. The three support rods 20 are deployed at the bottom of the circular base 22 through the first hinge 21 to form a triangular support surface, which can adapt to complex terrain such as slopes and ridges. The geometric symmetry of the circular base 22 and the even distribution of the three support rods 20 ensure that the center of gravity of the device is vertically downward to avoid falling over. Among them, three connecting rods 23 are fixedly installed at the center of the circular base 22, and a drive motor 24 is fixedly installed on the three connecting rods 23; three first trapezoidal blocks 25 are also fixedly installed at the bottom of the circular base 22, and steps 17 are set on the side of the first trapezoidal blocks 25.

[0043] In this embodiment, the balancing assembly 15 includes three telescopic components and a support ring 19. The telescopic components include a telescopic cylinder 16 and a telescopic rod 18. The telescopic cylinder 16 is fixedly mounted on the ring base 22, and the telescopic rod 18 is fixedly mounted on the support ring 19, which is used to raise the support ring 19. The support ring 19 is used to support the balancing main tube 10. The telescopic rod 18 and the telescopic cylinder 16 form a telescopic structure. When the main tube 10 rises, the support ring 19 rises synchronously, maintaining contact with the middle of the main tube 10, supporting the main tube 10 at three points.

[0044] Among them, the insect-attracting lamp 14 is electrically connected to the controller, which controls the insect-attracting lamp 14 to turn on and off at set time points (such as turning on at 18:00 every day and turning off at 7:00 every day). The sensor (including infrared sensor or ultrasonic sensor) is also connected to the controller signal to facilitate automatic control.

[0045] Example 2, based on Example 1 combined Figure 13-15As shown, the outer side of the support rod 20 is provided with symmetrically arranged strip grooves 201, the inner wall of the strip groove 201 is provided with a slide groove 202, the bottom of the strip groove 201 is hinged with an extension arm 203, the top of the extension arm 203 is hinged with a driving arm 204, the top of the driving arm 204 is inserted with a slide shaft 205, and the two ends of the slide shaft 205 are provided with side plates 206, and the side plates 206 are fixedly installed on the inner wall of the ring 207, and the ring 207 is provided with a notch 208 corresponding to the driving arm 204, and the outer wall of the ring 207 is embedded with a nut 209, and the internal thread of the nut 209 is connected to a locking bolt 210. Specifically, the support rod 20 is first inserted into the soil, and by loosening the locking bolt 210, the ring 207 can slide on the support rod 20. By pushing the ring 207 downward and sliding it, the slide rod shaft 205 slides in the slide groove 202, and the driving arm 204 and the extension arm 203 change from a "I" shape to a "V" shape. The "V"-shaped driving arm 204 and the extension arm 203 will extend into the soil, thereby increasing the firm grip of the support rod 20 on the soil.

[0046] Example 3, based on Example 2 combined Figure 7 、 Figure 12 As shown, the drive motor 24 is also located at the center of the annular base 22. The output end of the drive motor 24 is fixedly mounted with a screw shaft 241. The outer side of the screw shaft 241 is threadedly connected to a screw sleeve 242. The screw sleeve 242 is embedded in the inner wall of a fixed sleeve 243. The outer wall of the fixed sleeve 243 is fixedly mounted with a secondary rod 244. The secondary rod 244 is mounted on the inner wall of the main tube 10. Specifically, when the drive motor 24 drives the screw shaft 241 to rotate, the screw shaft 241 drives the screw sleeve 242 to move up and down (i.e., lift), and the entire main tube 10 will move up or down, conveniently adapting to different plant heights. The drive motor 24 is inserted into the bottom of the main tube 10 and is rigidly connected to the annular base 22 via three connecting rods 23 to provide vertical support. The step 17 of the first trapezoidal block 25 engages with the second trapezoidal block 28 of the adjustment mechanism 12 to achieve multi-level height locking of the main tube 10. The adjustment mechanism 12 also includes a limiting ring 26 and a second trapezoidal block 28. The bottom of the limiting ring 26 is rotatably mounted with the second trapezoidal block 28 via a second hinge 29. When the second trapezoidal block 28 engages with the first trapezoidal block 25, it supports the limiting ring 26. The limiting ring 26 is fixedly connected to the bottom of the main tube 10. A circular hole 27 is formed in the limiting ring 26, and the telescopic cylinder 16 passes through the circular hole 27. The restraint of the telescopic cylinder 16 and the circular hole 27 ensures the stability of the limiting ring 26's upward and downward movement. The limiting ring 26 rises with the main tube 10. The second trapezoidal block 28 engages with the step 17 of the first trapezoidal block 25 via the second hinge 29, preventing the main tube 10 from falling back. The telescopic cylinder 16 passes through the circular hole 27 of the limiting ring 26, limiting the lateral displacement of the main tube 10 and ensuring vertical lifting.

[0047] Example 4, based on Example 3 combined Figure 8 、 Figure 9 As shown, the insecticide mechanism 13 also includes two opposing upper and lower annular bodies 30. Each annular body 30 is uniformly and rotatably mounted with a plurality of elastic rods 31. A canvas 32 is installed between adjacent elastic rods 31. A sleeve 33 and a sleeve rod 34 are installed between the two annular bodies 30. The sleeve rod 34 is fixedly connected to the elastic rods 31, and the sleeve 33 is sleeved onto the two sleeve rods 34. The elastic rods 31 unfold as the main tube 10 rises, and the canvas 32 forms an umbrella-like structure, covering the top and sides of the corn plant. The sleeve 33 and sleeve rod 34 adjust the vertical spacing between the upper and lower insect traps 14 to accommodate plant height at different growth stages. A fixed rod 35 is installed between two adjacent sleeves 33, and the insect traps 14 are fixedly mounted on the fixed rod 35. The upper and lower annular bodies 30 are divided into four compartments by the sleeve 33 and sleeve rod 34. Each compartment is equipped with an insect trap 14, and the walls of each compartment are covered with reflective cloth 36. The two circular bodies 30 are divided into four spaces by a sleeve 33 and a sleeve rod 34. Each layer is independently installed with an insect trap lamp 14, covering high-injury areas such as about 0.8m (seedling stage), about 1.2m (small trumpet stage), and about 1.5m (grain filling stage). Reflective cloth 36 covers each space, reflecting light to the back of the middle and lower leaves of the crop, reducing blind spots under the light.

[0048] Example 5, based on any of the above examples, combined Figure 10 、 Figure 11 and Figure 17 As shown, a light emitting collimator 37 is installed on the periphery of the insecticidal mechanism 13 (a plurality of light emitting collimators 37 together form a ring structure), and the light emitting collimator 37 is also connected to the controller signal. The light emitting collimator 37 surrounds the insecticidal mechanism 13, and a plurality of evenly arranged light reflecting plates 38 are arranged on the side of the light emitting collimator 37. The light reflecting plates 38 are triangular prisms with an isosceles triangle cross section. The reflecting surfaces of the light reflecting plates 38 serve as two side surfaces of the triangular prism. An electric insecticidal net is set on the periphery of the light emitting collimator 37 and on the inner side of the light reflecting plates 38. (Most of the light emitted by the insect trap 14 and the light beam collimated by the light emission collimator 37 can pass through the through-holes of the electric insecticide net. When in use, pests can be killed as long as they come into contact with the electric insecticide net.) The distance between adjacent insecticide devices is no more than 50 meters to better meet the reflection of the light beams. The light reflection plate 38 reflects part of the light beams emitted by other adjacent insecticide devices. The electric insecticide net, all the light beams passing through the light emission collimator 37 and the light beams reflected by the light reflection plate 38 together form a net-like insecticide section between adjacent insecticide devices. Figure 17As shown, most of the light emitted by the insecticidal mechanisms 13 of the insecticidal devices on both sides is collimated by the light emission collimator 37 (the light after collimation by the light emission collimator 37 becomes a beam, and the concentration is greatly improved, so that the light emitted by the light source can be more concentratedly emitted to a specific area, reducing scattering and energy loss of light during propagation, and enhancing the range and intensity of attraction to pests). Part of the light is then emitted in the form of a beam toward the surrounding area and the middle insecticidal device. After receiving the light beam, the light reflector 38 on the middle insecticidal device will reflect it. In this way, the electric insecticidal net, the insecticidal mechanism 13, the light emission collimator 37, the light reflector 38 and the multiple insecticidal devices cooperate to jointly construct a mesh-like insecticidal section with multiple light beams 39 interlaced with each other. This mesh-like insecticidal section can cover pests near crop leaves (similar to covering pests with a net), not only having a very excellent insecticidal effect, but also significantly reducing the probability of pests on the crop flying away from the crop and the probability of them flying onto the crop. In particular, it can induce and kill pests between adjacent insecticidal devices.
