[0002] In recent years, environmental awareness has taken root in people's hearts. While developing the economy, the country has paid more attention to ecological protection, implementing large-scale afforestation activities. How to effectively accelerate the development of conventional seedling cultivation is a problem that needs to be solved in my country's forestry development. my country has continuously increased investment and encouraged afforestation, strengthening forestry protection and development while promoting economic development. With policy support, my country's conventional seedling cultivation technology has been effectively developed, which plays a vital role in the development of my country's forestry. Forestry includes the planting and management of various seedlings, among which pest and disease management is a crucial part. Pests and diseases are a collective term for diseases and insect pests, which often have adverse effects on forestry. Diseases such as pine wilt disease damage vascular tissue, causing pine tree death, and poplar canker affect wood quality; while leaf-eating insects in poplar trees eat away all the leaves, and longhorn beetles bore into the trunk, causing trees to die. These pests disrupt ecological balance, reduce biodiversity, and cause economic losses. Therefore, it is necessary to strengthen monitoring and early warning, promote biological control, and combine physical and chemical control to ensure the safety and sustainable development of forestry resources.

[0003] Existing forestry pest and disease trapping devices typically involve placing a trapping agent inside the device to attract pests, causing them to crawl inside and be captured, thus achieving the effect of trapping and eliminating pests. However, existing forestry pest and disease trapping devices have certain problems. The odor of the trapping agent relies solely on natural evaporation and natural wind diffusion, which limits its attraction range and is not conducive to better trapping pests, thus reducing the device's effectiveness in treating pests. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that existing forestry pest and disease trapping devices rely on natural wind for limited diffusion distance, and to propose a forestry seedling pest and disease trapping device.

[0005] To achieve the above objectives, this utility model employs the following technology: a forestry seedling pest and disease trapping device, comprising a support base, a limiting plate fixed on the support base via a support column, a rotating rod supported by a bearing along the center line of the support base and the limiting plate, a support disc and a wind vane fixed on the rotating rod, a light mechanism for light trapping, a support rod for supporting an odor trapping mechanism, and a diffusion mechanism for spreading the odor of the trapping agent further on the support disc, a counterweight ring and a tail fin fixed at both ends of the wind vane, and a height adjustment mechanism provided at the lower end of the support base plate.

[0006] As a further description of the above technical solution: the diffusion mechanism includes a guide plate fixed on a support disk, a top plate fixed on the guide plate, and the angle between the guide plate and the axis of the wind vane is 15°–30°.

[0008] As a further description of the above technical solution: the lighting mechanism includes a fixed plate fixed on a support disc, an insect-attracting lamp is provided on the fixed plate, and a detachable lampshade is provided on the fixed plate.

[0009] As a further description of the above technical solution: the height adjustment mechanism includes a first vertical rod connected to the support base by a thread, the first vertical rod being nested inside a second vertical rod, and a circular plate for stabilization being fixed at the lower end of the second vertical rod. Both the first and second vertical rods are provided with holes for placing bolts.

[0010] As a further description of the above technical solution: the wind vane is provided with a rotatable hook base.

[0011] As a further description of the above technical solution: the rotating rod is provided with a baffle to prevent it from moving upward.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: Through the diffusion mechanism in the pest trap, the rotation of the rotating rod drives the rotation of the supporting disc, making the axis of the diffusion mechanism parallel to the direction of natural wind movement. By utilizing the Venturi effect, the odor emitted by the odor trap is transmitted further by the wind, thereby attracting pests from afar.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] The core objective of this invention is to provide a forestry seedling pest trapping device. This device can transmit the scent of the attractant further than relying on natural wind through the diffusion mechanism 10, attracting pests from a greater distance. Furthermore, by cooperating with the light mechanism 7, the trapping efficiency can be improved.

[0018] Reference Figure 1 - Figure 6 The embodiment provides a forestry seedling pest and disease trapping device, including a support base 1, a support column 2, a limiting plate 3, a rotating rod 4, a support disc 5, a lighting mechanism 7, an odor trapping mechanism 8, and a diffusion mechanism 10. Among them, a support column 2 is fixed at the upper end of the support base 1, a limit plate 3 is fixed at the upper end of the support column 2, a bearing support that coincides with the axis of the support base 1 is provided at the upper end of the support base 1, and the limit plate 3 supports the rotating rod 4 that coincides with its axis through the bearing, and one end of the rotating rod 4 is located in the bearing seat. The support disc 5 is fixed on the rotating rod 4. The support disc 5 is equipped with a light mechanism 7 for light trapping, a support rod 9 for supporting the odor trapping mechanism 8, and a diffusion mechanism 10 for diffusing the odor of the attractant further.

[0019] Specifically, in order to make the wind vane 6 parallel to the direction of natural wind movement, the wind vane 6 is fixed to the upper end of the rotating rod 4. A tail fin 12 for generating torque is fixed to one end of the wind vane 6. In order to maintain the stability of the device, a counterweight ring 11 is fixed to the other end of the wind vane 6, so that the center of gravity of the wind vane 6 is located on the axis of the rotating rod 4.

[0020] The principle of the wind vane 6 being parallel to the direction of natural wind movement: When the angle between the direction of the wind and the wind vane 6 is a certain angle, the wind exerts pressure on the wind vane 6. This force can be decomposed into two wind forces, one parallel and one perpendicular to the wind vane 6. Since the wind-receiving area of ​​the counterweight ring 11 of the wind vane 6 is relatively small and the wind-receiving area of ​​the tail fin 12 is relatively large, the wind pressures they experience are not equal. The wind pressure perpendicular to the tail fin 12 generates a wind pressure torque, causing the wind vane 6 to rotate around the axis of the rotating rod 4 until the counterweight ring 11 of the wind vane 6 is aligned with the direction of the wind. Since the forces on both sides of the tail fin 12 are balanced, the wind vane 6 is then stable in a certain position.

[0021] During the rotation of the wind vane 6, the rotating rod 4 fixed at the lower end of the wind vane 6 rotates synchronously. The rotation of the rotating rod 4 causes the supporting disk 5 to rotate together. The rotation of the supporting disk 5 causes the upper diffusion mechanism 10 to rotate synchronously, so that the air inlet axis of the horn-shaped diffusion mechanism 10, which is composed of the guide plate 1001 and the top plate 1002, is parallel to the direction of wind movement. The two guide plates 1001 are fixed on the supporting disk 5, and the angle between the guide plate 1001 and the axis of the wind vane 6 is 15°-30°. The top plate 1002 is fixed at the upper end of the guide plate 1001. It should be noted that the cross-sectional area of ​​the air inlet of the diffusion mechanism 10 is larger than the cross-sectional area of ​​the air outlet.

[0022] The working principle of the diffusion mechanism 10 is based on the conclusion in fluid mechanics that the cross-section is inversely proportional to the flow velocity. As the wind enters through the air inlet of the diffusion mechanism 10, the channel of the diffusion mechanism 10 becomes narrower, resulting in a significant increase in kinetic energy at the outlet of the diffusion mechanism 10. According to Bernoulli's principle, as the wind passes through the diffusion mechanism 10, the static pressure of the wind is converted into dynamic pressure, reducing the loss of kinetic energy. In addition, natural wind has a spherical diffusion surface, and the diffusion surface at the outlet of the diffusion mechanism 10 is smaller than that of natural wind, thereby reducing the loss of momentum. As a result, the wind passing through the diffusion mechanism 10 travels a longer distance, which in turn drives the odor trapping mechanism 8 located at the front end of the air inlet of the diffusion mechanism 10 to spread the insect attractant odor further.

[0023] The odor trapping mechanism 8 includes a trapping cage 801 fixed on a support rod 9. To prevent pests from escaping the trapping cage 801, the lower end of the trapping cage 801 is cone-shaped. To facilitate the replacement of the insect attractant in the trapping cage 801, a detachable cage cover 802 is provided on the top of the trapping cage 801. A hanging rod 803 is fixed to the lower end of the cage cover 802, and an insect attractant rack 804 for placing the insect attractant is fixed to the lower end of the hanging rod 803. Pests enter the trapping cage 801 from the cone-shaped lower end of the trapping cage 801. Taking advantage of the poor perception of pests, the pests are trapped in the trapping cage 801.

[0024] To improve the trapping efficiency of the device, a lighting mechanism 7 is also fixed on the support disc 5. The lighting mechanism 7 includes a fixing plate 701 fixed on the support disc 5. An insect-attracting lamp 702 for attracting pests is provided on the fixing plate 701. In order to prevent pests from approaching the insect-attracting lamp 702 and to prevent rainwater from damaging the insect-attracting lamp 702, a detachable lamp cover 703 is connected to the fixing plate 701 by a snap fastener. The insect-attracting lamp 702 lures pests near the device, which are then attracted and captured by the odor trapping mechanism 8.

[0025] To make the device suitable for seedlings of different heights, a height adjustment mechanism 13 is provided at the lower end of the support base 1. The height adjustment mechanism 13 includes a first vertical rod 1301 connected to the support base 1 by a thread. The first vertical rod 1301 is nested inside a second vertical rod 1302. In order to keep the relative position of the first vertical rod 1301 and the second vertical rod 1302 unchanged, holes 1304 for placing bolts are provided in both the first vertical rod 1301 and the second vertical rod 1302. In order to improve the stability of the height adjustment mechanism 13, a circular plate 1303 for stabilization is fixed at the lower end of the second vertical rod 1302.

[0026] When the device needs to be adjusted in height, remove the bolts used to fix the relative positions of the first vertical rod 1301 and the second vertical rod 1302, then move the first vertical rod 1301 up and down to adjust it to the required position, and then put the bolts back into the hole 1304 that is fixed on the coaxial axis of the first vertical rod 1301 and the second vertical rod 1302, and tighten the bolts.

[0027] To facilitate the arrangement of the device, a rotatable hook base 14 is provided on the wind vane 6.

[0028] To prevent the rotating rod 4 from slipping when using the hook, a baffle 15 is provided on the rotating rod 4 to prevent it from moving upward.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
