Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of forestry pest trapping, in particular to a forestry pest trapping device. BACKGROUND

[0002] The forestry pest trapping technology is a key prevention and control means for the outbreak of pest populations in forest ecosystems, which is derived from the rising of pest diversity and the intensification of harm caused by global climate change and the expansion of plantations. This technology targets pests through pheromones, lights or food attractants, and combines physical capture or chemical killing methods to significantly reduce pesticide use and protect forest biodiversity.

[0003] The prior art has the following disadvantages: In the fruit tree planting system, the pest community shows a significant vertical stratification distribution characteristic: the scarab larvae (grubs) in the 0-50 cm soil layer near the ground cause seedling root stem to be eaten by eating, and the weevil adults on the ground directly eat the base of the tree trunk to form a ring-shaped boring mark; the dense habitat of the piercing-sucking mouthpart pest community in the 50-150 cm crown layer of the plant, including the aphid community gathered on the back of the tender shoots, the leafhopper population moving transversely between leaf veins, and the leaf-rolling moth larvae, which weaken the tree by directly feeding and transmitting viral diseases; and above 150 cm of the tree crown, fruit fly adults hover around mature fruit to lay eggs, and fruit borer pests use their developed mouthparts to pierce the fruit skin to suck juice. These high-altitude pests often cause the commercial value of the fruit to be zero. The current pheromone traps suspended in the middle of the tree trunk or the poison bait stations placed on the ground cannot cover all the ecological niches in the three-dimensional space of the fruit tree, and it is difficult to accurately trap and kill different height pests according to their different tendencies, resulting in a significant middle-high efficiency and a phenomenon of missing prevention at both ends. SUMMARY

[0004] In view of the deficiencies of the prior art, the present application provides a forestry pest trapping device, which solves the problem of limited pest trapping area existing today.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical scheme: a forestry pest trapping device, comprising a base and a ground rod for fixing the base, a sleeve one is arranged inside the base, a sleeve two is inserted into the sleeve one, and a plug rod is inserted into the sleeve two.

[0011] In some embodiments, a belt is arranged in a ring-shaped manner through the middle of the inner support leg, which is used to link multiple groups of inner support legs to facilitate the folding of multiple groups of inner support legs.

[0012] In some embodiments, a sliding groove is opened on the end face of the inner wall of the first sleeve, and a limiting block is arranged on the outer wall of the second sleeve, which can limit the travel of the second sleeve when the limiting block is clamped inside the sliding groove. A side slot one is opened on the side end of the first sleeve for accommodating the movement of the extension block to prevent the extension block from being blocked.

[0013] In some embodiments, a clamping rod is fixedly connected to the outside of the insertion rod for supporting the insertion rod, a side slot two is opened on the side end of the second sleeve for accommodating the movement of the clamping rod, and a semicircular recessed clamping groove is opened on the top of the second sleeve, which can be used to support the clamping rod.

[0014] In some embodiments, a long rod is arranged at the bottom of the insertion rod, which passes through the bottom of the second sleeve and has a disc-shaped structure at the end, which is inverted and buckled at the bottom of the second sleeve. The long rod is used to drive the second sleeve to move up synchronously when the insertion rod moves, thereby forming linkage.

[0015] In some embodiments, a cover plate is arranged at the top of the insertion rod, and a handle is arranged at the top of the cover plate for facilitating the lifting of the operator.

[0016] In some embodiments, a placement plate is arranged on the side wall of the second connecting rod, which is used to support the yellow stick insect plate, and a spring clamp is arranged at the side end of the placement plate for clamping the yellow stick insect plate. The second connecting rod is stretched by the vertical movement of the first connecting rod and the second sleeve, so that the yellow stick insect plate can also be lifted or lowered, thereby enabling the yellow stick insect plate to reach a height of 50-70 cm.

[0024] Please seeFigures 1-7 In the embodiment, the forestry pest trapping device comprises a base 1, an earth peg 2 for fixing the base 1, a sleeve 1 3 arranged in the base 1, a sleeve 2 4 inserted into the sleeve 1 3, and a plug 5 inserted into the sleeve 2 4. The sleeve 2 4 and the plug 5 are vertically extended from the sleeve 1 3, so that the pest trapping structures are arranged at different heights, thereby trapping different pests at different heights, such as near the ground, under the leaves, and at the top of the tree, and the pest trapping is more comprehensive.

[0025] The sleeve 1 3 is bolted to the bottom end of the base 1. The earth peg 2 is arranged in three groups and is distributed in an equilateral triangle position relationship (as shown in Figure 2 The arrangement helps to improve the overall stability of the base 1 after installation.

[0026] In order to fix the sleeve 2 4 when it is moved upward to the end of the stroke, an extension block 9 is fixedly connected to the outside of the sleeve 2 4. A connecting rod 1 0 is rotatably arranged at the bottom of the extension block 9, and a connecting rod 2 1 1 is rotatably arranged at the bottom of the connecting rod 1 0. The extension block 9 is used to support the installation of the connecting rod 1 0 and the connecting rod 2 1 1. A ring 1 9 for supporting the rotating connection of the connecting rod 2 1 1 is fixedly installed inside the base 1. The ring 1 9 is embedded in the base 1 and exposed at the slotted part of the base 1 (as shown in Figure 4 Thus, the extension block 9 and the ring 1 9 are connected by the connecting rod 1 0 and the connecting rod 2 1 1. An inner support foot 1 2 is rotatably arranged at the side end of the connecting rod 2 1 1 for supporting the connecting rod 1 0, the extension block 9, and the sleeve 2 4. A convex ring 8 is arranged outside the bottom of the sleeve 1 3 for bearing the inner support foot 1 2. The bottom end of the inner support foot 1 2 is in the shape of a pincer opening (as shown in Figure 6 The inner support foot 1 2 can bear against the convex ring 8, thereby achieving the effect of supporting the sleeve 2 4 (at the top end of the stroke) ; A band 1 3 is arranged in a ring shape through the inner support foot 1 2, and the band 1 3 is used to keep multiple groups of inner support feet 1 2 linked (as shown in Figure 5 The band 1 3 facilitates the folding of multiple groups of inner support feet 1 2.

[0027] A sliding groove 1 6 is arranged on the inner wall end face of the sleeve 1 3, and a limiting block 1 7 is arranged on the outer wall of the sleeve 2 4. When the limiting block 1 7 is clamped in the sliding groove 1 6, the movement of the sleeve 2 4 can be limited in stroke, thereby preventing the sleeve 2 4 from rotating when moving. A side slot 1 8 is arranged at the side end of the sleeve 1 3 for accommodating the movement of the extension block 9, preventing the extension block 9 from being blocked.

[0028] In order to fix the insertion rod 5 when it moves to the end of the stroke, a support rod 22 is fixed to the outside of the insertion rod 5, a side slot 20 is opened at the side end of the sleeve 2 for accommodating the movement of the support rod 22, and a semicircular recessed clamping groove 21 is opened at the top of the sleeve 2, which can be used to provide support for the support rod 22. Thus, when the insertion rod 5 moves up and down inside the sleeve 2, the support rod 22 passes through the side slot 20. If it is necessary to fix the insertion rod 5, it can be rotated by 45° when it moves to the end of the stroke, so that the support rod 22 is placed on the clamping groove 21, thereby fixing the position of the insertion rod 5.

[0029] A long rod 23 is provided at the bottom of the insertion rod 5, which passes through the bottom of the sleeve 2 and has a disc-shaped structure (as shown in Figure 5 ) at the end, which is inverted at the bottom of the sleeve 2. The long rod 23 is used to move the sleeve 2 synchronously when the insertion rod 5 moves, thereby forming a linkage.

[0030] A cover plate 6 is provided at the top of the insertion rod 5, and a handle 7 is provided at the top of the cover plate 6 for the operator to lift. When the operator lifts the handle 7, the insertion rod 5 is pulled up, and the sleeve 2 is pulled up by the long rod 23. Thus, only one-way pulling force is needed to make the sleeve 2 and the insertion rod 5 extend upwards with the sleeve 1 as the center. The cover plate 6 can also provide shading for the overall structure, preventing the direct sunlight in summer from causing the accelerated consumption of the pest trapping material, and preventing the erosion of rainwater.

[0031] In order to achieve different heights of pest trapping effect, a placement plate 14 is provided on the side wall of the connecting rod 2, which is used to support the yellow sticky insect plate. A spring clamp 15 (as shown in Figure 6 ) is also provided at the side end of the placement plate 14 for clamping the yellow sticky insect plate. The connecting rod 2 is stretched by the vertical movement of the connecting rod 1 and the sleeve 2, so that the yellow sticky insect plate can also be lifted or lowered, thereby making the yellow sticky insect plate reach 50-70 cm (middle of the plant); An embedded groove 25 is opened at the bottom of the base 1, which is distributed in a ring shape at the bottom of the base 1 (as shown in Figure 2 ). The embedded groove 25 is used to place the bait plate (sugar vinegar liquid mixed with phoxim insecticide), thereby providing pest trapping effect for the 0-50 cm (near ground layer) area; A surrounding net 24 is provided at the bottom of the cover plate 6, which is woven by metal wires and is clamped at the bottom of the cover plate 6. The surrounding net 24 is used to spray methyl eugenol and increase the attachment area of methyl eugenol, thereby achieving pest trapping coverage of the 70-120 cm (top of the plant) area in cooperation with the yellow sticky glue.

[0032] In the embodiment, the multi-height pest trapping coverage of the fruit tree seedling from the ground to the top of the tree can be achieved by the surrounding net 24, the placing plate 14 and the embedded groove 25. The operator can place the base 1 on the soil in the area where the fruit tree seedlings are densely planted, and then insert the ground peg 2 into the ground to keep the base 1 stable and fixed. Then, the operator only needs to hold the handle 7 and make an upward action to pull the insertion rod 5 upward. The insertion rod 5 pulls the sleeve 2 upward through the long rod 23. When the sleeve 2 is pulled up, the connecting rod 2 is pulled by the connecting rod 1, and the inner support foot 12 swings at the side end. The multiple groups of inner support feet 12 distributed in a ring are connected by the belt 13. The operator only needs to fold them to the middle part to make the end of the inner support foot 12 clamped outside the convex ring 8 and abut against the convex ring 8, thereby providing support for the sleeve 2. When the insertion rod 5 moves to the end of the stroke, it only needs to be turned by 45° to make the clamping rod 22 clamped on the clamping groove 21. Thus, the insertion rod 5 and the sleeve 2 are fixed at the end of the stroke, and the cover plate 6 reaches the height of the top of the fruit tree seedling. If it is necessary to store the structure, only need to turn the insertion rod 5 by 45° to make the clamping rod 22 embedded in the side slot 2, and then pull the inner support foot 12 outward to reset and recover the sleeve 2. The overall structure is close to the base 1 after recovery, and the cover plate 6 provides shielding protection for the whole (as shown in Figure 7 ).

[0033] Finally, it should be noted that the above only describes the preferred embodiments of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent replacements to some technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
