Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pest trapping technology, and in particular relates to a directional trapping device for locust pests. Background Technology
[0002] Food source traps utilize the locusts' preference for the scent of grasses (such as wheat and corn) or specific baits. The attractant (such as wheat bran, corn flour mixed with insecticide or adhesive) is placed in a special container or trap tray and placed in areas with high locust infestations. The locusts are attracted to the food by the scent and are then captured or killed. This method is suitable for low-density monitoring or small-scale prevention and control.
[0003] Barrel-shaped traps that use food to catch locusts have a relatively small trap entrance designed to prevent rainwater from entering the interior. However, because the trap opening is small, the trapping efficiency is low. Directly increasing the opening would allow a large amount of rainwater to enter the interior, greatly reducing the rainproof effect. This results in the relatively low practicality of conventional barrel-shaped traps.
[0004] To address this problem, we propose a directional trapping device for locust pests. Utility Model Content
[0005] The purpose of this invention is to address the problem of the low practicality of conventional barrel-shaped traps by proposing a directional trapping device for locust pests.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: A directional trapping device for locust pests includes an insect box with an annular cover on the top. A conical hopper is fixedly connected inside the annular cover. A guide frame is provided on the inner side of the conical hopper. The outer periphery of the guide frame is fixedly connected to the annular cover. A food box is slidably and sealed on the guide frame. A spring is fitted on the upper part of the guide frame. The upper end of the spring is fixedly connected to the guide frame, and the lower end of the spring is fixedly connected to the food box. An annular sealing cover is threaded and sealed on the upper end of the food box. The annular sealing cover is fitted over the guide frame and the spring. A water hopper is fixedly connected to the upper end of the annular sealing cover. Open the ring-shaped sealing cap, place the food into the food box, and then tighten the ring-shaped sealing cap onto the food box. The spring force acts upward on the food box, opening the gap between the food box and the conical hopper. The arc-shaped structure at the bottom of the food box guides the locusts into the conical hopper, which then guides them into the insect box. Increasing the gap in the conical hopper increases the trapping efficiency. When it rains, use the water bucket to collect rainwater. The gravity of the rainwater acts downward on the water bucket, which in turn acts downward on the ring-shaped sealing cap, which in turn acts downward on the food box, causing the food box to close downward. This reduces the gap in the conical hopper, decreasing the possibility of rainwater entering the insect box, thus balancing trapping efficiency with rain protection.
[0007] Preferably, the guide frame includes a guide post, the lower part of which is fixedly connected to a connecting rod, the upper end of which is fixedly connected to an annular cover, the guide post passes through a conical hopper, and a gap is left between the guide post and the conical hopper for insects to fall into.
[0008] Preferably, the food box includes a box body, a conical box fixedly connected to the lower end of the box body, a slit in the conical box, a sealing sleeve fixedly connected inside the box body and the conical box, and a water-blocking cover fixedly connected to the outside of the box body. The sealing sleeve slides and seals against the box body, and the lower end of a spring is fixedly connected to the sealing sleeve. Food is placed between the box body and the sealing sleeve, allowing the food to enter between the conical box and the sealing sleeve. The slit in the conical box allows the food's aroma to dissipate, facilitating the capture of locusts.
[0009] Preferably, the annular sealing cover includes a cover body, inside which a first sealing ring and a second sealing ring are fixedly connected. The cover body is threaded onto the box body. The lower end of the second sealing ring is in sealing contact with a sealing sleeve, and the lower end of the first sealing ring is in sealing contact with the upper end of the box body. The first and second sealing rings seal the gap between the box body and the sealing sleeve, and the annular sealing cover blocks the gap between the box body and the sealing sleeve, preventing rainwater from falling into the box body.
[0010] Preferably, the water hopper includes a hopper body, with a water-blocking shell fixedly connected inside the hopper body. A drain hole is provided at the lower end of the hopper body, and the lower end of the hopper body is fixedly connected to the upper end of the cover. After rainwater falls into the hopper body, when the drainage rate through the drain hole is less than the inflow rate, water accumulates inside the hopper. This accumulated water acts downwards on the hopper body, causing the hopper body to act downwards on the food container, causing the food container to slide down and narrowing the gap between the food container and the conical hopper, facilitating automatic rain protection.
[0011] Preferably, the water bucket further includes an annular knob, which is fixedly connected to the upper end of the water-blocking shell. Turning the annular knob rotates the water-blocking shell, which in turn rotates the bucket body, which in turn rotates the annular sealing cover, facilitating the operation of the water bucket rotating the annular sealing cover.
[0012] In summary, the technical effects and advantages of this utility model are as follows: 1. Open the ring-shaped sealing cap, put the food into the food box, and then tighten the ring-shaped sealing cap on the food box. Use the spring force to act upward on the food box, opening the gap between the food box and the cone-shaped hopper. Use the arc-shaped structure at the bottom of the food box to guide the locusts into the cone-shaped hopper. The cone-shaped hopper guides the locusts into the insect box. Increasing the gap in the cone-shaped hopper increases the trapping efficiency. When it rains, use the water bucket to collect rainwater. Use the gravity of the rainwater to act downward on the water bucket, which in turn acts downward on the ring-shaped sealing cap, which in turn acts downward on the food box, causing the food box to close downward. This reduces the gap in the cone-shaped hopper and decreases the possibility of rainwater entering the insect box, thus balancing trapping efficiency and rain protection.
[0013] 2. Place the food between the box and the sealing sleeve, allowing the food to enter the conical box and the sealing sleeve. Use the gaps in the conical box to allow the food's aroma to escape, making it easier to capture locusts with the food.
[0014] 3. Use the first sealing ring and the second sealing ring to seal the gap between the box body and the sealing sleeve, and use the annular sealing cover to block the gap between the box body and the sealing sleeve to prevent rainwater from falling into the box body.
[0015] 4. After rainwater falls into the hopper, when the drainage speed of the drain hole is less than the water inflow speed, water accumulates in the hopper. The accumulated water acts downward on the hopper, which in turn acts downward on the food container, causing the food container to slide down and reduce the gap between the food container and the conical hopper, thus facilitating automatic rain protection.
[0016] 5. Turning the ring knob rotates the water baffle, which in turn rotates the bucket, which in turn rotates the ring sealing cover, making it easy to operate the bucket and rotate the ring sealing cover. Attached Figure Description

[0019] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments.
[0020] like Figure 1 As shown, a directional trapping device for locust pests includes an insect box 1, an annular cover 7 covering the upper part of the insect box 1, a conical hopper 8 fixedly connected inside the annular cover 7, a guide frame 2 provided on the inner side of the conical hopper 8, the outer periphery of the guide frame 2 fixedly connected to the annular cover 7, a food box 3 slidably and sealed on the guide frame 2, a spring 6 sleeved on the upper part of the guide frame 2, the upper end of the spring 6 fixedly connected to the guide frame 2, the lower end of the spring 6 fixedly connected to the food box 3, an annular sealing cover 4 threadedly and sealed on the upper end of the food box 3, the annular sealing cover 4 sleeved on the outside of the guide frame 2 and the spring 6, and a water hopper 5 fixedly connected to the upper end of the annular sealing cover 4.
[0021] like Figure 1 and 2 As shown, the guide frame 2 includes a guide post 21, with a connecting rod 22 fixedly connected to the lower part of the guide post 21. The upper end of the connecting rod 22 is fixedly connected to the annular cover 7. The guide post 21 passes through the conical hopper 8, and a gap is left between the guide post 21 and the conical hopper 8 for insects to fall into. The guide post 21 is used to guide the food box 3 to rise and fall.
[0022] like Figure 1 and 3 As shown, the food box 3 includes a box body 31, with a conical box 32 fixedly connected to the lower end of the box body 31. A slit is provided in the conical box 32. A sealing sleeve 34 is fixedly connected inside the box body 31 and the conical box 32, and a water-blocking cover 33 is fixedly connected to the outside of the box body 31. The sealing sleeve 34 slides and seals the food. The lower end of the spring 6 is fixedly connected to the sealing sleeve 34. Food is placed between the box body 31 and the sealing sleeve 34, allowing the food to enter between the conical box 32 and the sealing sleeve 34. The slit in the conical box 32 allows the food's odor to escape.
[0023] like Figure 1 and 4 As shown, the annular sealing cover 4 includes a cover body 41. A first sealing ring 42 and a second sealing ring 43 are fixedly connected inside the cover body 41. The cover body 41 is threaded onto the box body 31. The lower end of the second sealing ring 43 is in sealing contact with the sealing sleeve 34, and the lower end of the first sealing ring 42 is in sealing contact with the upper end of the box body 31. The first sealing ring 42 and the second sealing ring 43 seal the gap between the box body 31 and the sealing sleeve 34.
[0024] like Figure 1 and5 As shown, the water hopper 5 includes a hopper body 51, with a water-blocking shell 52 fixedly connected inside the hopper body 51. A drain hole 54 is provided at the lower end of the hopper body 51, and the lower end of the hopper body 51 is fixedly connected to the upper end of the cover body 41. After rainwater falls into the hopper body 51, when the drainage speed of the drain hole 54 is less than the water inflow speed, water accumulates inside the hopper body 51. The accumulated water acts downward on the hopper body 51, causing the hopper body 51 to act downward on the food box 3, causing the food box 3 to slide down and reduce the gap between the food box 3 and the conical hopper 8.
[0025] like Figure 1 and 5 As shown, the water bucket 5 also includes an annular knob 53, which is fixedly connected to the upper end of the water-blocking shell 52. Turning the annular knob 53 causes the water-blocking shell 52 to rotate, which in turn causes the bucket body 51 to rotate, and the bucket body 51 causes the annular sealing cover 4 to rotate.
[0026] Working principle: Open the annular sealing cover 4, put the food into the food box 3, and then close the annular sealing cover 4 tightly on the food box 3. The elastic force of the spring 6 acts upward on the food box 3, opening the gap between the food box 3 and the conical hopper 8. The arc-shaped structure at the bottom of the food box 3 guides the locusts to fall into the conical hopper 8. The conical hopper 8 guides the locusts into the insect box 1. The trapping efficiency is increased by increasing the gap on the conical hopper 8. When it rains, the water bucket 5 collects rainwater. The gravity of the rainwater acts downward on the water bucket 5, which in turn acts downward on the annular sealing cover 4. The annular sealing cover 4 then acts downward on the food box 3, causing the food box 3 to close downward, reducing the gap on the conical hopper 8 and decreasing the possibility of rainwater entering the insect box 1.
