Description

Technical Field

[0001] The utility model belongs to the technical field of forestry pest control, and specifically relates to a hazel weevil trapping device. Background Art

[0002] The hazel weevil is a major pest in natural hazel forests and planted hazel economic forests. The larvae mainly damage the fruits and cause losses. The adults feed on young buds, fruits, leaves and branches. It is mainly captured by traps and collected and cleaned up regularly.

[0003] The trapping device is to place volatile hazel weevil pheromones as a lure in the collection space, so that the hazel weevil enters the collection space along a designated channel. The collection space generally uses electric shock to kill insects or sticky insect boards to capture, and can be barrel-shaped, square or spherical, etc. In order to reduce the windward surface, it is often designed to be spherical.

[0004] When trapping hazel weevils in the existing hazel forest, a spherical trapping device is hung on a branch, and the hazel weevils are stuck to the funnel-shaped sticky insect board. However, it is difficult for the trap core to cover the entire area of ​​the funnel-shaped sticky insect board, and the funnel-shaped sticky insect board is not convenient to rotate, so the hazel weevils are often concentrated in the area where the funnel-shaped sticky insect board is facing the trap core, resulting in a blank area on the funnel-shaped sticky insect board. For this reason, a hazel weevil trapping device is proposed. Utility Model Content

[0005] The utility model aims to provide a hazel weevil trapping device, which can drive the funnel-shaped insect sticking plate to rotate along the annular slide rail, change the insect sticking area of ​​the funnel-shaped insect sticking plate below the attractant core box, and is conducive to reducing the blank area on the funnel-shaped insect sticking plate.

[0006] The technical solutions adopted in this utility are as follows:

[0007] A hazel weevil trapping device comprises a transparent spherical shell, wherein the transparent spherical shell is an open structure on the lower surface, and an annular slide rail, a funnel-shaped insect sticking plate and a rotating shaft are fixed to the opening in sequence from bottom to top, the annular slide rail is detachably installed at the opening of the transparent spherical shell, the funnel-shaped insect sticking plate is slidably connected to the annular slide rail, the upper end of the funnel-shaped insect sticking plate extends upward into the interior of the transparent spherical shell and is fixedly connected to the upper end of the rotating shaft, the lower end of the rotating shaft passes through the funnel-shaped insect sticking plate and the annular slide rail in the axial direction and is fixed with a plurality of fan blades at intervals, and when working, the transparent spherical shell is hung on a tree branch, The opening faces downward, and the pheromone emitted by the attractant box is used to attract the hazelnut weevils, so that they pass through the annular slide rail and the funnel-shaped insect sticky board into the transparent spherical shell, and finally fall onto the funnel-shaped insect sticky board and are stuck. The transparent spherical shell on the branch is at a higher position, and the air flow is obvious. The air flow is used to push a number of fan blades to drive the rotating shaft, which can then drive the funnel-shaped insect sticky board to rotate along the annular slide rail, changing the funnel-shaped insect sticky board to the insect sticking area below the attractant box, so that the hazelnut weevils are distributed on the annular surface of the funnel-shaped insect sticky board as much as possible, which is beneficial to reducing the blank area on the funnel-shaped insect sticky board and improving the utilization rate.

[0008] A hook is fixed on the upper surface of the transparent spherical shell. The transparent spherical shell is manually lifted by a push rod, and the hook is hooked on a branch to complete the hanging, which is easy to operate. Furthermore, sharp nails are welded inside the hook, which can be inserted into the branch for reinforcement and are not easy to slip off.

[0009] The funnel-shaped insect sticky board is fixed with a guide channel, which is in a vertical funnel shape and extends downward along the inside of the funnel-shaped insect sticky board. A spacing is left between the guide channel and the rotating shaft, which extends downward to increase the area for guiding the hazel weevils to climb, making it easier for the hazel weevils to enter the transparent spherical shell.

[0010] A stainless steel sleeve is provided on the fixed sleeve at the upper end of the rotating shaft, and a plurality of support rods fixedly connected to the funnel-shaped insect sticking board are distributed along a circumferential array on the outside of the stainless steel sleeve. While reinforcing the rotating shaft, sufficient space is left between the rotating shaft and the funnel-shaped insect sticking board to facilitate the passage of hazelnut weevils.

[0011] A threaded seat ring is threadedly installed at the opening of the transparent spherical shell, and the inner side of the threaded seat ring is fixedly connected to the outer side of the annular slide rail. The threaded seat ring can be installed at the opening of the transparent spherical shell along the thread by rotating forward, and can be unscrewed along the thread by rotating reversely. The funnel-shaped insect sticky plate can be detached to clean insect corpses or living insects and add an insect glue layer.

[0012] A bottom ring is integrally installed on the lower edge of the transparent spherical shell to reinforce the opening of the transparent spherical shell and reduce cracking or deformation caused by extrusion of the threaded seat ring.

[0013] The technical effects achieved by this utility model are:

[0014] The utility model discloses a hazel weevil trapping device. When working, a transparent ball shell is hung on a tree branch with an opening facing downward, and a lure core box is used to emit pheromones to attract the hazel weevils, so that the hazel weevils pass through an annular slide rail and a funnel-shaped insect sticking plate and enter the transparent ball shell, and finally fall onto the funnel-shaped insect sticking plate and are stuck. The transparent ball shell on the tree branch is at a higher position, and air flow is obvious. The air flow is used to push a plurality of fan blades to drive the rotating shaft, and then the funnel-shaped insect sticking plate can be driven to rotate along the annular slide rail, so that the funnel-shaped insect sticking plate is located in the insect sticking area below the lure core box, so that the hazel weevils are distributed on the annular surface of the funnel-shaped insect sticking plate as much as possible, which is beneficial to reducing the blank area on the funnel-shaped insect sticking plate and improving the utilization rate.

[0021] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0022] like Figure 1-4As shown, a hazel weevil trapping device comprises a transparent spherical shell 1, and a Chinese utility model with reference to announcement number CN205337302U, a hazel weevil trapping device, further comprising an attractant core hanging ring and an attractant core box, the attractant core hanging ring is fixed on the upper wall of the transparent spherical shell 1, the attractant core box is suspended on the attractant core hanging ring, the transparent spherical shell 1 can be transparent, the transparent spherical shell 1 is an opening structure on the lower surface, and the opening is fixed with an annular slide rail 2, a funnel-shaped insect sticking plate 3 and a rotating shaft 4 in sequence from bottom to top, the annular slide rail 2 is detachably installed at the opening of the transparent spherical shell 1, the funnel-shaped insect sticking plate 3 is a porous funnel structure, and an insect glue layer is provided on the outer arc surface to stick to the hazel weevil, the funnel-shaped insect sticking plate 3 is slidably connected to the annular slide rail 2, the upper end of the funnel-shaped insect sticking plate 3 extends upward into the interior of the transparent spherical shell 1 and is fixedly connected to the upper end of the rotating shaft 4, the lower end of the rotating shaft 4 passes through the funnel-shaped insect sticking plate 3 and the annular slide rail 2 along the axial direction, and is fixed with a plurality of The fan blades 5, one end of which is fixedly connected to the lower end of the rotating shaft 4. The hazel weevil is often oval in shape after adulthood, with a length of 6 to 8 mm and a width of 3.0 to 3.6 mm. Since the hazel weevil likes to eat leaves, etc., it often concentrates on the crown area. When working, the transparent spherical shell 1 is hung on the branch with the opening facing downward, and the pheromone emitted by the attracting core box is used to attract the hazel weevil, so that it passes through the annular slide rail 2 and the funnel-shaped insect sticking plate 3 and enters the transparent spherical shell 1, and finally falls on the funnel-shaped insect sticking plate 3 and is stuck. The transparent spherical shell 1 on the branch is in a higher position, and the air flow is obvious. The air flow is used to push a plurality of fan blades 5 to drive the rotating shaft 4, so that the funnel-shaped insect sticking plate 3 can be driven to rotate along the annular slide rail 2, and the funnel-shaped insect sticking plate 3 is changed to be located in the insect sticking area below the attracting core box, so that the hazel weevil is distributed on the annular surface of the funnel-shaped insect sticking plate 3 as much as possible, which is conducive to reducing the blank area on the funnel-shaped insect sticking plate 3 and improving the utilization rate.

[0023] Furthermore, the spherical surface of the transparent spherical shell 1 is easy to disperse the airflow after facing the wind, and the impact of the airflow is relatively small, and generally no obvious swing occurs, so that the fan blades 5 below it can continue to rotate against the wind without manual or electric drive to rotate. In addition, insect luring is often carried out in remote areas where it is not easy to connect to the electricity. If batteries are used, the maintenance cost will be greatly increased.

[0024] like Figure 1 As shown, a hook 6 is fixed on the upper surface of the transparent spherical shell 1. The transparent spherical shell 1 is manually lifted by a push rod, and the hook 6 is hooked on the branch to complete the hanging, which is easy to operate. Furthermore, sharp nails are welded inside the hook 6, which can be inserted into the branch for reinforcement and are not easy to slip off.

[0025] like Figure 1 and Figure 3As shown, the funnel-shaped insect sticky board 3 is fixed with a guide channel 7, which is in a vertical funnel shape and extends downward along the inside of the funnel-shaped insect sticky board 3. A spacing is left between the guide channel 7 and the rotating shaft 4, which extends downward to increase the area for guiding the hazel weevils to climb, making it easier for the hazel weevils to enter the transparent spherical shell 1.

[0026] like Figure 3 and Figure 4 As shown, a stainless steel sleeve 8 is fixedly provided on the upper end of the rotating shaft 4, and a plurality of support rods 9 fixedly connected to the funnel-shaped insect sticking plate 3 are distributed along a circular array on the outside of the stainless steel sleeve 8. While reinforcing the rotating shaft 4, sufficient space is left between the rotating shaft 4 and the funnel-shaped insect sticking plate 3 to facilitate the passage of hazelnut weevils.

[0027] like Figure 1 and Figure 3 As shown, a threaded seat ring 10 is threadedly installed at the opening of the transparent spherical shell 1, and the inner side of the threaded seat ring 10 is fixedly connected to the outer side of the annular slide rail 2. The threaded seat ring 10 can be installed at the opening of the transparent spherical shell 1 along the thread by rotating forward, and can be unscrewed along the thread by rotating reversely, so that the funnel-shaped insect sticky plate 3 can be detached to clean insect corpses or living insects and add an insect glue layer.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, a bottom ring 11 is integrally installed at the lower edge of the transparent spherical shell 1 to improve the structural strength at the opening of the transparent spherical shell 1, reinforce the opening of the transparent spherical shell 1, and reduce cracking or deformation caused by extrusion of the threaded seat ring 10.

[0029] The working principle of the utility model is as follows: when working, the transparent spherical shell 1 is hung on the branch with the opening facing downward, and the pheromone emitted by the attractant core box is used to attract the hazelnut weevils, so that they pass through the annular slide rail 2 and the funnel-shaped insect sticking plate 3 into the transparent spherical shell 1, and finally fall onto the funnel-shaped insect sticking plate 3 and are stuck. The transparent spherical shell 1 on the branch is at a higher position, and the air flow is obvious. The air flow is used to push a plurality of fan blades 5 to drive the rotating shaft 4, which can then drive the funnel-shaped insect sticking plate 3 to rotate along the annular slide rail 2, change the funnel-shaped insect sticking plate 3 to the insect sticking area below the attractant core box, and make the hazelnut weevils distributed on the annular surface of the funnel-shaped insect sticking plate 3 as much as possible, which is conducive to reducing the blank area on the funnel-shaped insect sticking plate 3 and improving the utilization rate.
