Description

Technical Field

[0001] This invention relates to the field of pest control technology, and in particular to a rat trapping device for fruit trees. Background Technology

[0002] In recent years, the consumption of high-quality tropical fruits such as macadamia nuts and avocados in China has been increasing, and the cultivation area has been expanding. With the promotion of these high-quality fruit tree plantings, rodent infestation has become increasingly serious, causing significant losses to yield and quality. The main rodents damaging macadamia nuts and avocados include house mice, brown rats, field mice, and vole. During the fruit-growing season, they climb the trees and eat the fruit, causing losses. Surveys have found that rodent damage can cause up to 30% of the damage to macadamia nuts and up to 20% to avocados, severely reducing the economic benefits of cultivation. Therefore, it is necessary to research scientific, effective, and environmentally friendly control methods. Summary of the Invention

[0003] The present invention aims to provide a rodent trapping device for fruit trees, which solves the problem of low economic benefits caused by rodent damage in macadamia nut and avocado cultivation.

[0004] To achieve the above objectives, the technical solution of the present invention is as follows: a rat trapping device for fruit trees, comprising a sleeve, the inner wall of which is coated with peanut oil, and a peanut crumb bag located in the middle of the sleeve, wherein the peanut crumb bag is not in contact with the inner wall of the sleeve, and a cover is threadedly connected to the end of the sleeve.

[0005] Furthermore, a connecting rod is slidably connected inside the sleeve, and multiple first rotating rods are circumferentially connected to the connecting rod. Each first rotating rod is connected to a compression spring, and a first elastic cloth is connected between every two adjacent first rotating rods. When the first rotating rod is inside the sleeve, the first elastic cloth is in a taut state, and the compression spring is in a compressed state.

[0006] Furthermore, the sleeve has symmetrically provided sliding grooves for the connecting rod to slide, the connecting rod is threadedly connected to an adjusting rod, and the outer wall of the sleeve has an adjusting chamber covering the adjusting rod.

[0007] With the above settings, the length of the connecting rod and the extended sleeve can be controlled by the adjusting rod, thereby controlling the specific positions of the first elastic cloth and the first rotating rod. When the first rotating rod and the first elastic cloth are outside the sleeve, the first elastic cloth can be unfolded by the compression spring, thereby using the first elastic cloth to cover the opening of the sleeve, which helps to prevent rainwater from entering and maintain the stability of this trapping device.

[0008] Furthermore, a fixing frame is fixedly connected to the top of the connecting rod, and multiple second rotating rods are circumferentially rotatably connected to the fixing frame. A torsion spring is connected between each second rotating rod and the fixing frame, and a second elastic cloth is connected between every two adjacent second rotating rods. When the torsion spring is not twisted, the second elastic cloth is in a taut state.

[0009] Furthermore, a push rod located below the fixed frame is slidably connected to the connecting rod, and the end of the push rod can abut against each of the second rotating rods.

[0010] Furthermore, all the outer ends of the second rotating rods are connected to an elastic sealing ring, which abuts against the bottom of the second elastic cloth and the bottom of the second rotating rod.

[0011] With the above setup, the second elastic cloth, the second rotating rod, and the elastic sealing ring can form a funnel-shaped liquid-holding area. When the peanut oil on the inner wall of the sleeve is depleted due to rodents entering, peanut oil can be poured into the liquid-holding area. Then, the push rod is used to rotate and open all the second rotating rods, allowing the peanut oil to slide relatively evenly along the first elastic cloth and the first rotating shaft onto the inner wall of the sleeve, thus replenishing the peanut oil on the inner wall of the sleeve. This saves time and effort and ensures that the peanut oil on the inner wall of the sleeve is spread relatively evenly. At the same time, when using the first elastic cloth and the first rotating rod for rain protection, rainwater can also wash the peanut oil on the surface of the first elastic cloth onto the tree trunk, which is beneficial for trapping rodents.

[0012] Furthermore, a capture net is connected to the end of the sleeve, and a gap is left between the capture net and the cover.

[0013] Furthermore, a tension sensor is embedded at the end of the sleeve, and the tension sensor is connected to the capture net via a connecting rope. An indicator light located on the side wall of the sleeve is electrically connected to the tension sensor.

[0014] With the above setup, the trap net can be used to capture rodents. At the same time, the tension generated by the trap net on the tension sensor triggers an indicator light, reminding the grower that it is time to replenish the peanut oil inside the sleeve, and at the same time, the captured rodents are collected.

[0015] Furthermore, the bottom of the cover is provided with a concave portion, and vent holes are symmetrically opened on the concave portion. The vent holes are located directly below the center of the hollow area inside the sleeve. A rotating shaft is rotatably connected to the outside of the concave portion. Negative pressure blades and rotating blades are distributed circumferentially on the rotating shaft. The negative pressure blades do not extend beyond the concave portion, and the rotating blades are located outside the cover.

[0016] With the above configuration, the peanut oil dripping from the inner wall of the sleeve can be collected by the concave part and the side wall of the cover, avoiding waste of peanut oil. At the same time, the rotating blade can rotate under the action of natural wind, thereby driving the rotating shaft to rotate. After the rotating shaft rotates, it can use the negative pressure blade to draw the outside wind into the sleeve through the vent, so that the aroma of peanut oil or peanut crumbs can be dispersed outside the sleeve, thus achieving the trapping of rodents.

[0017] Furthermore, a drive motor is threadedly connected to the inside of the cover, and the drive motor is coaxially connected to the rotating shaft.

[0018] With the above setup, the drive motor can actively rotate the shaft, which helps to overcome the situation of no wind or quickly diffuse the aroma of peanut oil or crushed peanuts when the device is installed, which is beneficial for attracting rodents and thus protecting the fruit trees.

[0019] Compared with existing technologies, the beneficial effects of this solution are:

[0020] 1. This solution enables the capture of rodents, thereby protecting the fruits of tropical fruit trees such as macadamia nuts and avocados, and improving the economic benefits of planting tropical fruit trees.

[0021] 2. This design enables the diffusion of the aroma of peanut oil and crushed peanuts, which is more conducive to the capture of rodents. At the same time, this device can also provide rain protection, maintaining the stability of the device in capturing rodents. Furthermore, it is convenient to replenish the peanut oil on the inner wall of the sleeve after capturing rodents, thus improving the continuity of the device in capturing rodents.

[0022] 3. This solution employs physical control measures, utilizing simple devices to trap and kill rodents on fruit trees. This effectively reduces the rodent population, thereby minimizing damage to the fruit and improving economic benefits. Furthermore, this solution uses simple materials without the involvement of chemical agents; the materials are recyclable, reducing environmental pollution. Simultaneously, it only affects rodents, protecting birds and other wildlife, thus offering environmental benefits. Attached Figure Description

[0030] The present invention will be further described in detail below through specific embodiments:

[0031] The reference numerals in the accompanying drawings include: sleeve 1, slide groove 2, connecting rod 3, first rotating rod 4, compression spring 5, first elastic cloth 6, adjusting rod 7, adjusting chamber 8, fixing frame 9, second rotating rod 10, second elastic cloth 11, elastic sealing ring 12, push rod 13, peanut crushing bag 14, cover 15, inner recess 16, drive motor 17, rotating shaft 18, vent hole 19, negative pressure blade 20, rotating blade 21, tension sensor 22, indicator light 23, and capture net 24.

[0032] Example 1

[0033] like Figures 1 to 4 As shown, a rat trapping device for fruit trees includes a sleeve 1. In this embodiment, the sleeve 1 is a 40cm plastic drainage pipe with an outer diameter of 110mm. The inner wall of the sleeve 1 is coated with peanut oil. Symmetrical grooves 2 are provided inside the sleeve 1 for sliding connecting rods 3. A T-shaped connecting rod 3 is slidably connected within two grooves 2. Four first rotating rods 4 are circumferentially connected to the upper side of the connecting rod 3. A compression spring 5 is connected between each first rotating rod 4 and the connecting rod 3. A first elastic cloth 6 is connected between every two adjacent first rotating rods 4. When the first rotating rod 4 is inside the sleeve 1, the first elastic cloth 6 is taut, and the compression spring 5 is compressed. An adjusting rod 7 is threaded to the left end of the connecting rod 3. An adjusting chamber 8 is provided on the outer wall of the sleeve 1, covering the upper end of the adjusting rod 7.

[0034] A fixed frame 9 is fixedly connected to the top of the connecting rod 3, located above the first rotating rod 4. The fixed frame 9 consists of a fixed column and four fixed rods distributed circumferentially. Four second rotating rods 10 are rotatably connected to the ends of the four fixed rods of the fixed frame 9. A torsion spring is connected between each second rotating rod 10 and the fixed frame 9. A second elastic cloth 11 is connected between every two adjacent second rotating rods 10. When the torsion spring is not twisted, the second elastic cloth 11 is in a taut state. All the outer ends of the second rotating rods 10 are connected to an elastic sealing ring 12. The elastic sealing ring 12 abuts against the bottom of the second elastic cloth 11 and the bottom of the second rotating rod 10, sealing the gap between the second elastic cloth 11 and the first elastic cloth 6. A push rod 13 is also slidably connected to the upper side of the connecting rod 3, located between the fixed frame 9 and the first rotating rod 4. The shape of the push rod 13 is the same as that of the fixed frame 9, and the end of the push rod 13 abuts against each second rotating rod 10.

[0035] A peanut crumb bag 14 located in the middle of the sleeve 1 is suspended by a thin rope at the bottom of the connecting rod 3. The peanut crumb bag 14 is not in contact with the inner wall of the sleeve 1. A cover 15 is also threadedly connected to the lower end of the sleeve 1.

[0036] The method of using this trapping device is as follows:

[0037] S1. Take out the sleeve 1 and adjust the position of the connecting rod 3 by adjusting the adjusting rod 7 to keep the first rotating rod 4 and the first elastic cloth 6 inside the sleeve 1.

[0038] S2. Pour an appropriate amount of peanut oil into the liquid-holding area formed by the second elastic cloth 11, the second rotating rod 10, and the elastic sealing ring 12. Then push the push rod 13 downward. At this time, the push rod 13 pushes the four second rotating rods 10 outward, and the elastic sealing ring 12 expands slightly outward, so that the peanut oil slides relatively evenly from the gap between the elastic sealing ring 12 and the first elastic cloth 6 along the first rotating rod 4 and the first elastic cloth 6. Finally, it is relatively evenly distributed on the inner wall of the sleeve 1 through the first elastic cloth 6 and the first rotating rod 4, thereby achieving uniform application of peanut oil, improving the application efficiency of peanut oil, and helping to improve the continuous capture of rodents by this trapping device.

[0039] S3. After the peanut oil is applied, use the adjusting rod 7 to push the first rotating rod 4 and the first elastic cloth 6 out of the sleeve 1. At this time, the first rotating rod 4 unfolds outward under the action of the spring, and the first elastic cloth 6 is in a stretched state. The area enclosed by the first elastic cloth 6 can block the opening of the sleeve 1, preventing the device from being washed by rainwater. At the same time, it allows the opening to be opened, making it easier for rodents to enter, thus maintaining the reliability of the device in catching rodents. Furthermore, the junction of the first elastic cloth 6 with the branches of macadamia nuts, avocados, etc., provides convenience for rodents to enter the sleeve 1, which is beneficial for catching rodents.

[0040] S4. Attach sleeve 1 to fruit trees such as macadamia nuts and avocados, which have many branches and are susceptible to rodent damage, using wire, maintaining an angle of 45°-60° between sleeve 1 and the ground. This device is not suitable for fruit trees with relatively straight and single trunks.

[0041] S5. Inspect the device every three days. If rodents are found, remove them immediately and clean the sleeve 1 and cover 15. Then repeat step S3 and check if the peanut crumb bag 14 needs to be added. If no rodents are caught for a long time, check the peanut crumb bag 14 to prevent the bait from becoming moldy. If mold appears, replace it immediately.

[0042] Example 2

[0043] like Figure 5 As shown, the difference between this embodiment and Embodiment 1 is only that: in this embodiment, the bottom of the cover 15 is provided with a recessed portion 16, the center of which is threadedly connected to a drive motor 17, and the output shaft of the drive motor 17 is coaxially connected to a rotating shaft 18. A through hole is provided at the center of the recessed portion 16 for the output shaft of the drive motor 17 to pass through. Multiple vent holes 19 are symmetrically provided on the recessed portion 16, arranged symmetrically with respect to the drive motor 17. The rotating shaft 18 also has four negative pressure blades 20 and four rotating blades 21 distributed circumferentially. All the negative pressure blades 20 do not extend beyond the range of the recessed portion 16, and the rotating blades 21 are located outside the cover 15.

[0044] The difference between this embodiment and Embodiment 1 lies only in the following: In step S4, after the sleeve 1 is fixed, the drive motor 17 can be turned on. The drive motor 17 drives the negative pressure blades 20 to draw air into the cover 15 and sleeve 1, causing the air to flow in a directional direction. This airflow disperses the aroma of peanut oil and crushed peanuts. Simultaneously, due to the obstruction of the first elastic cloth 6, the dispersed aroma can move towards the bottom of the fruit tree, which is beneficial for attracting rodents through the fragrance. The drive motor 17 can be turned off after being turned on for a period of time. Then, the natural wind drives the rotating blades 21 and rotating shaft 18 to rotate, allowing the aroma of peanut oil and crushed peanuts to disperse during the operation of this device. If the natural wind volume is insufficient to attract rodents due to the external geographical environment, the drive motor 17 can be intermittently started to actively diffuse the scent.

[0045] Example 3

[0046] like Figure 6 and Figure 7As shown, the difference between this embodiment and Embodiment 2 is only that: in this embodiment, a tension sensor 22 is embedded in the lower end of the sleeve 1, and an indicator light 23 installed on the side wall of the sleeve 1 is electrically connected to the tension sensor 22. With the help of the tension sensor 22 and the indicator light 23, the trapping device that has captured rodents can be observed, thus improving the detection efficiency of the trapping device in determining whether rodents have been captured. The tension sensor 22 is also connected to a trapping net 24, which is attached to the lower end of the sleeve 1. A gap is left between the trapping net 24 and the cover 15. With the help of the trapping net 24, rodents can be collected, while minimizing the impact of rodent movement inside the sleeve 1 or cover 15 on the overall rodent-catching operation.

[0047] The difference between the usage method of this embodiment and that of Embodiment 2 is only that: in step S5, when checking the trapping devices, it is possible to directly observe the indicator light 23 of each trapping device to determine which trapping device has captured rodents, thereby transferring the rodents in the corresponding trapping device and replacing the peanut oil and peanut crumb packet 14. If the trapping device has not captured rodents within the predetermined time, it is necessary to check the peanut oil and peanut crumb packet 14 of the corresponding trapping device, and replenish the peanut oil and replace the peanut crumb packet 14 in a timely manner.

[0048] The above are merely embodiments of the present invention, and common knowledge such as specific structures and / or characteristics in the solutions are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of the present invention, and these should also be considered within the scope of protection of the present invention. These modifications and improvements will not affect the effectiveness of the implementation of the present invention or the practicality of the patent. The scope of protection claimed in this application should be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
