Description

Technical Field

[0001] This invention relates to the field of forest pest and disease control equipment technology, and in particular to an insect-attracting device for forest pest and disease control. Background Technology

[0002] In the process of controlling forest pests and diseases, equipment such as insect-attracting lamps, pheromone traps, trapping buckets, and sticky insect boards are commonly used to attract and inactivate pests in forest areas. Although existing insect-attracting devices can achieve a certain attraction effect, they still have the following shortcomings.

[0003] First, some insect-attracting devices rely on fixed openings or fixed channels to release attractants, resulting in a relatively simple attractant diffusion path, which is not easy to form a disturbing diffusion in the natural wind environment of the forest area.

[0004] Secondly, some insect-attracting devices rely on motors, controllers, sensors, or solar power systems for operation, which are complex in structure. The damp, rainy, and temperature-different-day environments in forest areas can easily cause electrical component failures.

[0005] Third, the inactivation solution in the collection cup is prone to reduced inactivation effect due to evaporation, dilution by rainwater, or accumulation of insects, and ordinary replenishment structures are difficult to maintain the inactivation performance of the replenished solution.

[0006] Fourth, the forest area contains a lot of leaves, pine needles and bark debris, which can easily block conventional horizontal filters, affecting rainwater filtration and the stability of replenishment.

[0007] Fifth, even after pests enter the trapping device, they may still escape along the cylinder wall, funnel wall, or collection cup wall, affecting the stability of the trapping process.

[0008] Therefore, there is a need for a forest pest control device that is primarily mechanically driven, can utilize natural wind to alter the state of the insect-attracting channel, and works in conjunction with structures for replenishing, filtering, and collecting inactivating liquid. Summary of the Invention

[0009] The purpose of this invention is to provide an insect-attracting device for the control of forest pests and diseases, thereby solving the problems mentioned above.

[0010] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This invention discloses an insect-attracting device for controlling forest pests and diseases, comprising a hook, a hanger at the lower end of the hook, a wind cup rotatably mounted on the hanger, a rotating shaft at the center of the wind cup, an umbrella-shaped cover on the lower side of the hanger, a connecting ring at the center of the lower end of the umbrella-shaped cover, and an annular rain collection trough connected below the connecting ring. A cylindrical cam mechanism is provided after the shaft extends downward through the connecting ring. A crank-slider mechanism is provided below the output end of the cylindrical cam mechanism. A rotating inner cylinder is provided at the output end of the crank-slider mechanism. The rotating inner cylinder is rotatably disposed inside the fixed outer cylinder. Both the rotating inner cylinder and the fixed outer cylinder have mutually cooperating diffusion holes on their side walls. The annular rain collection groove and the fixed outer cylinder are connected together by a support plate. A labyrinth channel is provided at the lower end of the fixed outer cylinder. A funnel is provided below the labyrinth channel. A collection cup is provided at the lower end of the funnel. An overflow port is provided on the collection cup. A replenishment bottle is provided on the upper end of the labyrinth channel away from the fixed outer cylinder. An inactivating agent slow-release box is provided above the replenishment bottle and communicates with it. An installation plate is provided between the inactivating agent slow-release box and the annular rain collection trough. An inactivating liquid inlet pipe is provided between the replenishment bottle and the collection cup. An overflow pipe is provided at the upper part of the replenishment bottle. The pipeline of the inactivating agent slow-release box is connected to the annular rain collection trough. A filter device is provided on the pipeline between the inactivating agent slow-release box and the annular rain collection trough.

[0011] Furthermore, the umbrella-shaped cover is a cover body that is high in the middle and low at the outer edge, the outer edge is a drip edge with an arc structure, and the annular rain collection groove is located below the drip edge; the gap between the annular rain collection groove and the lowest point of the umbrella-shaped cover is less than 1 cm.

[0012] Furthermore, the cylindrical cam mechanism includes an auxiliary support frame, which is disposed below the support plate and located below the annular rain collection groove. A cylindrical cam is rotatably mounted inside the auxiliary support frame. The cylindrical cam is disposed together with the rotating shaft. A roller is disposed in the cam groove of the cylindrical cam. A telescopic rod is disposed at the end of the roller away from the cylindrical cam. The top of the telescopic rod passes through the auxiliary support frame and is slidably disposed in the guide hole of the annular rain collection groove.

[0013] Furthermore, the crank-slider mechanism includes a slide rail, a slider is disposed inside the slide rail, a connecting rod one is hinged to the center of the slider via a hinge shaft, the other end of the connecting rod one is hinged to the connecting rod two, the other end of the connecting rod two is provided with a rotating disk, the rotating disk is disposed together with the rotating inner cylinder, and a slot is provided on the side wall of the slide rail for the connecting rod one to move.

[0014] Furthermore, the filtration device includes a filter cartridge mounting groove, with its upper and lower ends connected to the pipeline. A vertical filter cartridge is snapped into the filter cartridge mounting groove. The filter cartridge mounting groove has an open structure on one side, through which the vertical filter cartridge is snapped into the filter cartridge mounting groove. A transparent sealing plate is provided on the side of the vertical filter cartridge away from the open structure, and a sealing ring is provided between the sealing plate and the outer frame of the open structure.

[0015] Furthermore, the maze passage includes an upper mounting frame disposed together with the fixed outer cylinder and a lower mounting frame disposed together with the funnel, and a maze structure is provided between the upper mounting frame and the lower mounting frame.

[0016] Furthermore, the maze structure includes several reverse arc plates located in the inner circle and several forward arc plates located in the outer circle. The reverse and forward arc plates have opposite arc directions. Several reverse / forward arc plates are equidistantly distributed circumferentially, and there are gaps between the reverse and forward arc plates.

[0017] Furthermore, the lower opening of the funnel extends into the collecting cup, and the inner surface of the funnel is treated with a smooth finish.

[0018] Furthermore, the inactivating agent slow-release box contains a slow-release block of salt or neutral detergent.

[0019] Furthermore, a float valve is provided inside the collection cup, and the valve needle of the float valve is set together with the valve at the outlet end of the inactivation liquid inlet pipe.

[0020] Compared with the prior art, the beneficial technical effects of the present invention are as follows: This invention relates to a forest pest control device that uses a wind cup to drive a rotating shaft, which in turn drives a cylindrical cam mechanism. The cylindrical cam mechanism, through a crank-slider mechanism, drives a rotating inner cylinder, thus forming a mechanical transmission structure driven by natural wind, reducing the use of electronic control components. Furthermore, a maze-like passage is formed between the rotating inner cylinder, the fixed outer cylinder, and the mounting plate. Pests enter the fixed outer cylinder and follow a winding path into the funnel and collection cup, reducing the probability of pests escaping along a straight path. The annular rainwater collection trough, replenishment bottle, inactivator slow-release box, vertical filter cartridge, and inactivator inlet pipe constitute a replenishment path. Liquid added to the collection cup is treated by the inactivator slow-release box, reducing the impact of rainwater directly diluting the inactivator. Simultaneously, the vertical filter cartridge, inserted into the filter cartridge mounting slot, is less likely to be completely covered by leaves and pine needles compared to a horizontal filter screen, and is easier to remove and clean. In summary, the insect-attracting device for forest pest control of the present invention uses natural wind mechanical transmission to reduce electrical control components, a maze passage to prevent pests from escaping, a matching liquid replenishment structure to reduce the dilution of the inactivation solution by rainwater, and a vertical filter cartridge that is not easily clogged and is easy to clean.

[0023] like Figure 1-7 As shown, a forest pest control device includes a hook 1, a hanger 2 installed at the lower end of the hook 1, a wind cup 3 rotatably installed on the hanger 2, and a rotating shaft 6 installed at the center of the wind cup 3, the rotating shaft 6 rotating synchronously with the wind cup 3.

[0024] An umbrella-shaped cover 4 is installed on the lower side of the hanger 2. A connecting ring 5 is installed at the center of the lower end of the umbrella-shaped cover 4, and an annular rain collection trough 7 is connected below the connecting ring 5. The umbrella-shaped cover 4 is a cover body that is higher in the middle and lower at the outer edge. The outer edge is an arc-shaped drip edge, and the annular rain collection trough 7 is located below the drip edge. The gap between the annular rain collection trough 7 and the lowest point of the umbrella-shaped cover 4 is less than 1 cm, allowing fallen leaves and debris to fall into the trough and into the device without obstructing rainwater from falling into the annular rain collection trough 7. Figure 7 As shown, rainwater flows along the outer surface of the umbrella-shaped cover 4 to the outer edge and then falls into the annular rain collection trough 7, instead of directly entering the device.

[0025] The rotating shaft 6 extends downward through the connecting ring 5 and is fitted with a cylindrical cam mechanism 8. A crank-slider mechanism 9 is installed below the output end of the cylindrical cam mechanism 8. A rotating inner cylinder 10 is installed at the output end of the crank-slider mechanism 9. An attractant is placed inside the rotating inner cylinder 10, and a door is provided at the end of the rotating inner cylinder 10 away from the crank-slider mechanism 9 for holding the rotating inner cylinder 10. The rotating inner cylinder 10 is rotatably mounted inside a fixed outer cylinder 11. To ensure rotational stability, a circumferential limiting groove is provided on the inner sidewall of the fixed outer cylinder 11, and a matching limiting protrusion is provided on the outer sidewall of the rotating inner cylinder 10. Both the rotating inner cylinder 10 and the fixed outer cylinder 11 have mutually cooperating diffusion holes on their sidewalls. Through this structure, when the rotating inner cylinder 10 rotates relative to the fixed outer cylinder 11, the diffusion holes on their sidewalls overlap, stagger, or partially overlap, thereby changing the outward diffusion path of the attractant.

[0026] The annular rainwater collection trough 7 and the fixed outer cylinder 11 are installed together by a support plate 21. The support plate 21 is used to support the upper structure on the one hand, and to provide an installation foundation for the annular rainwater collection trough 7, the cylindrical cam mechanism 8, and the subsequent liquid replenishment and filtration structure on the other hand.

[0027] A labyrinth channel 23 is installed at the lower end of the fixed outer cylinder 11. A funnel 12 is installed below the labyrinth channel 23, and a collection cup 13 is installed at the lower end of the funnel 12. An overflow port 14 is installed on the collection cup 13 to drain excess liquid from the collection cup 13 and prevent overflow. To further control the liquid level, a float valve can be installed inside the collection cup 13. The valve needle of the float valve is configured to cooperate with the valve at the outlet end of the inactivation liquid inlet pipe 15, thereby automatically controlling the liquid inlet state when the liquid level in the collection cup 13 reaches a predetermined position.

[0028] A replenishment bottle 16 is installed on the upper end of the maze passage 23, away from the fixed outer cylinder 11. An inactivating agent slow-release box 18, communicating with the replenishment bottle 16, is installed above it. A mounting plate 22 is installed between the inactivating agent slow-release box 18 and the annular rain collection trough 7. The mounting plate 22 supports the inactivating agent slow-release box 18, the replenishment bottle 16, and their piping structure, and separates the upper rain collection structure from the lower replenishment structure. The inactivating agent slow-release box 18 contains a salt or neutral detergent slow-release block. An inactivating liquid inlet pipe 15 is installed between the replenishment bottle 16 and the collection cup 13. An overflow pipe 17 is installed at the upper part of the replenishment bottle 16 to drain excess liquid when the liquid level is too high. The inactivating agent slow-release box 18 is connected to the annular rain collection trough 7 via piping. A filter device is installed on the piping between the inactivating agent slow-release box 18 and the annular rain collection trough 7. When rainwater passes through the inactivator slow-release box 18, some components are dissolved or carried away, thus forming a replenishing solution with inactivation effect. The liquid then enters the collection cup 13 through the inactivator inlet pipe 15. Thus, the liquid in the collection cup 13 is not simply rainwater, but inactivator solution or replenishing solution treated by the inactivator slow-release box 18.

[0029] The lower opening of the funnel 12 extends into the collection cup 13, and the inner surface of the funnel 12 is smooth to reduce the possibility of pests staying along the inner wall of the funnel.

[0030] The cylindrical cam mechanism 8 includes an auxiliary support frame 801, which is mounted on the support plate 21 below the annular rain collection groove 7. A cylindrical cam 802 is rotatably mounted inside the auxiliary support frame 801, and the cylindrical cam 802 is mounted together with the rotating shaft 6. A roller 803 is installed in the cam groove of the cylindrical cam 802, and a telescopic rod 804 is installed at the end of the roller 803 away from the cylindrical cam 802. The top of the telescopic rod 804 passes through the auxiliary support frame 801 and is slidably installed in the guide hole 701 of the annular rain collection groove 7.

[0031] The wind cup 3 rotates under the action of natural wind, driving the rotating shaft 6 to rotate. 6 synchronously drives the cylindrical cam 802 to rotate, and the cam groove of the cylindrical cam 802 drives the roller 803 and the telescopic rod 804 to reciprocate. Since the telescopic rod 804 passes through the guide hole 701, the reciprocating motion of the telescopic rod 804 is guided and restricted, thereby converting the rotational motion of the cylindrical cam mechanism 8 into a stable axial reciprocating motion.

[0032] The crank-slider mechanism 9 includes a slide rail 901, a slider 902 installed inside the slide rail 901, a connecting rod 903 hinged to the center of the slider 902 via a hinge shaft, the other end of the connecting rod 903 hinged to the connecting rod 904, a rotating disk 905 installed at the other end of the connecting rod 904, the rotating disk 905 being installed together with the rotating inner cylinder 10, and a slot 906 for the connecting rod 903 to move on the side wall of the slide rail 901.

[0033] The reciprocating motion of the telescopic rod 804 acts on the crank-slider mechanism 9, causing the slider 902 to reciprocate along the slide rail 901. Connecting rod 1 903 and connecting rod 2 904 then move in tandem, driving the rotating disk 905 to rotate. The rotating disk 905 is fixedly connected to the rotating inner cylinder 10, thus allowing the rotating inner cylinder 10 to rotate periodically with the rotating disk 905.

[0034] The rotating inner cylinder 10 and the fixed outer cylinder 11 are in a relative rotational relationship. Both the rotating inner cylinder 10 and the fixed outer cylinder 11 have diffusion holes on their side walls. When they rotate relative to each other, the diffusion holes change between aligned and misaligned states, causing the inducer release channel to change accordingly. This structure does not require an additional motor drive; it mainly relies on the mechanical transmission driven by the wind cup 3.

[0035] The filtration device includes a filter cartridge mounting groove 20, with its upper and lower ends connected to pipelines. A vertical filter cartridge 19 is fitted into the filter cartridge mounting groove 20. The filter cartridge mounting groove 20 has an open side, allowing the vertical filter cartridge 19 to be inserted into the groove through the open side for easy disassembly and installation. A transparent sealing plate is installed on the side of the vertical filter cartridge 19 away from the open side, facilitating observation to determine if filter cartridge replacement is needed. A sealing ring is installed between the sealing plate and the outer frame of the open side to prevent leakage.

[0036] The maze passage 23 includes an upper mounting frame 2303 installed with the fixed outer cylinder 11 and a lower mounting frame 2304 installed with the funnel 12. A maze structure is installed between the upper mounting frame 2303 and the lower mounting frame 2304. The maze structure includes several reverse arc plates 2302 located in the inner circle and several forward arc plates 2301 located in the outer circle. The arc directions of the reverse arc plates 2302 and the forward arc plates 2301 are opposite. Several reverse arc plates 2302 / forward arc plates 2301 are equidistantly distributed circumferentially, and there are gaps between the reverse arc plates 2302 and the forward arc plates 2301. Through this structure, pests need to move downward along the curved path formed by the arc plates and then fall into the collection cup 13 through the funnel 12. Since the passage path is not straight, it is not easy to form a direct return path.

[0037] The working process of this invention is as follows: In use, the attractant is placed at the corresponding position in the rotating inner cylinder 10, and the device is suspended from a tree branch, support, or other load-bearing structure in the forest area via the hook 1. Under the action of natural wind, the wind cup 3 rotates, driving the rotating shaft 6 and the cylindrical cam mechanism 8 at its lower end to move. The cylindrical cam mechanism 8 then drives the rotating inner cylinder 10 to rotate through the crank-slider mechanism 9, causing the diffusion holes between the rotating inner cylinder 10 and the fixed outer cylinder 11 to change continuously.

[0038] Guided by the attractant, pests pass through the maze passage 23 and funnel 12 into the collection cup 13. Rainwater is collected by the umbrella-shaped cover 4 into the annular rainwater collection trough 7, and after passing through the filter device and the inactivator slow-release box 18, it enters the inactivation liquid inlet pipe 15 and then replenishes the collection cup 13. The float valve structure inside the collection cup 13 can work with the inactivation liquid inlet pipe 15 to control the liquid level. The overflow port 14 and the overflow pipe 17 are used together to drain excess liquid.

[0039] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
