DETAILED DESCRIPTION

[0020] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0021] like Figure 1-6 As shown, the utility model provides a height-adjustable forestry pest control device, including a support base 1 and a pest trap 2, the support base 1 and the pest trap 2 are connected by a lifting mechanism 3, the pest trap 2 includes a rain cover 21, a shell 22, an electric grid 23, a collecting bucket 24 and a trapping light 25, the electric grid 23 is located inside the shell 22 and is connected to one end of the shell 22, the cross-section of the electric grid 23 and the shell 22 forms a spiral line structure, the two ends of the shell 22 are connected by an insect entry plate 26, a plurality of insect entry holes 27 are provided on the insect entry plate 26, the rain cover 21 and the collecting bucket 24 are respectively located at the top and top of the shell 22 and the electric grid 23, the trapping light 25 is located in the center of the electric grid 23, the lifting mechanism 3 includes a fixed column 31 and a movable column 32 slidably installed in the fixed column 31, and a driving member for driving the movable column 32 to rise and fall is provided in the movable column 32.

[0022] like Figure 1-4 As shown, the insect trap 2 is detachably mounted on the top of a movable column 32 via a support rod and a bolt. The position of the movable column 32 within the fixed column 31 is adjusted by a drive member, causing the insect trap 2 to rise or fall. During insect trapping, the trapping light 25 attracts the insects, which enter the housing 22 through the insect entry hole 27 and travel along the path of the spiral wire structure toward the trapping light 25. The spiral wire path forms a maze-like structure, preventing the insects from escaping. During their flight along the spiral wire, the insects within the housing 22 may contact the electric grid 23 and be electrocuted. After being electrocuted, the insects fall into the collection hopper 24. In this embodiment, the path of the spiral wire structure gradually narrows as it travels toward the trapping light 25, further increasing the probability of the insects contacting the electric grid 23 and being electrocuted.

[0023] A photovoltaic panel 28 is provided on the top of the rain cover 21 , and a battery 29 electrically connected to the photovoltaic panel 28 is provided inside the rain cover 21 . The output end of the battery 29 is electrically connected to the trapping light 25 and the power grid 23 .

[0024] like Figure 2 As shown, the photovoltaic panel 28 converts solar energy into electrical energy and stores it in the battery 29, which provides electrical energy for the trapping light 25 and the power grid 23.

[0025] The collecting hopper 24 is connected to an insect attractant placement box 211 via a bracket 210 .

[0026] like Figure 3 As shown, the insect attractant placement box 211 is used to prevent the pest attractant from luring some non-phototactic pests into the housing 22.

[0027] The insect inlet hole 27 is a cone-shaped structure, and a collecting bag is connected to the bottom of the collecting hopper 24.

[0028] like Figure 2 As shown, the conical insect inlet hole 27 can further prevent the pests from escaping, and the collecting bag is mounted on the bottom of the collecting bucket 24, so that the captured pest bodies can be collected conveniently by regularly replacing the collecting bag.

[0029] The driving member includes a rotating shaft 33, a gear 34 and a rack 35. Straight groove lifting holes 36 are provided on both sides of the movable column 32. Both ends of the rotating shaft 33 pass through the straight groove lifting holes 36 and are rotatably installed in the fixed column 31. The gear 34 is installed on the rotating shaft 33. The rack 34 is fixedly set in the movable column 32 and meshes with the gear 34. Either end of the rotating shaft 33 passes through the fixed column 31 and is provided with a driving hole 37.

[0030] like Figure 5-6 As shown, a drive hole 37 is defined at one end of the rotating shaft 33. During use, an Allen wrench or other cylindrical tool can be inserted into the drive hole 37. By rotating the Allen wrench, the rotating shaft 33 rotates, which in turn rotates the gear 34. The gear 34 then drives the movable post 32, which is fixedly connected to the rack 35, to rise or fall within the fixed post 31, thereby steadily raising or lowering the pest trap 2. In this embodiment, the provision of the drive hole 37 also serves to prevent unauthorized personnel from tampering with the rotating shaft 33, thereby affecting the insect trapping effect.

[0031] The movable column 32 is provided with a plurality of limiting screw holes 38 , and the fixed column 31 is provided with a locking bolt 39 for fixing the movable column 32 .

[0032] like Figure 5As shown, after the movable column 32 is raised and lowered in the fixed column 31 , the position of the movable column 32 in the fixed column 31 can be locked and fixed by screwing the locking bolt 39 and threading it into the limiting screw hole 38 .

[0033] Principle of use: When in use, first fix the base 1 on the ground, and at the same time install the pest trap 2 on the movable column 32. According to the required height, insert the Allen wrench into the drive hole 37 and rotate the Allen wrench to control the movable column 32 to rise in the fixed column 31. After adjusting to a certain height, screw the locking bolt 39 to thread the locking bolt 39 into the limiting screw hole 38 to fix the position of the adjusted movable column 32. Through this lifting mechanism 3, the trap 2 can be stably raised and lowered during the process of adjusting its height.

[0034] The trapping process of the pest trap 2: under the action of the trapping light 25 or the insect attractant, the pests enter the shell 22 through the insect entrance hole 27. After entering the shell 22, the pests are electrocuted by the electric grid 23. After being electrocuted to death, they enter the collection bag along the collection bucket 24. After the pests enter the shell 22, the path of the vortex line structure and the cone-shaped insect entrance hole 27 can prevent the pests from escaping, thereby improving the insect catching effect.

[0035] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art may make various modifications, additions, or substitute similar methods to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
