Description

Technical Field

[0001] This utility model belongs to the field of pest control technology, and in particular relates to a device for controlling underground pests. Background Technology

[0002] Peony is a perennial herbaceous plant belonging to the genus Paeonia in the family Paeoniaceae. It is also known as wild peony, native white peony, and peony flower. In China, the peony symbolizes love, friendship, and farewell. It is one of the oldest cultivated ornamental flowers in China, and its roots, called "white peony," have medicinal uses, including analgesic, antispasmodic, blood-activating, and menstrual-regulating effects. Therefore, peonies are widely cultivated in my country.

[0003] During cultivation, because peony roots are underground, they are susceptible to damage from underground pests, which can eat away at the roots and affect the peony's value. Therefore, various control methods are used to protect peonies from these pests, the most common being the application of pesticides to the ground. However, this method has some drawbacks: 1. Pesticides are easily washed away by rainwater, reducing their effectiveness; 2. Pesticides can easily come into contact with peony leaves under wind conditions, contaminating the leaves and affecting the peony's ornamental value. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an underground pest control device that inserts itself into the ground to directly deliver the pesticide, avoiding residue and runoff on the surface and enabling more precise targeting of pests. Furthermore, a top plate is installed above the device to prevent rainwater ingress, reducing pesticide loss and ensuring long-term effectiveness.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A device for controlling underground pests includes a hollow screw, an arc-shaped cover at the upper end of the screw, a top plate mounted on the inside of the arc-shaped cover and above the screw via a bracket, a plurality of ear plates for connecting blades mounted in the middle of the screw, and the screw divided into upper and lower parts by the ear plates as the midpoint, the upper part having threads for connecting with a nut, and the lower part being a smooth rod body, and an inverted cone head at the bottom end of the screw;

[0007] The lower end of the nut is movably connected to the lifting cylinder. A slot is opened in the lifting cylinder at the position corresponding to the ear plate, and a locking block is provided at the lower end of the lifting cylinder.

[0008] Furthermore, the upper surface of the cone head is provided with an annular holding groove around the outside of the screw, and multiple discharge grooves are provided at the lower end of the screw. A diversion cone plate is provided at the center of the upper surface of the cone head, which can prevent the drug from accumulating at the bottom of the screw and preventing it from flowing out, so that the drug can flow out evenly from each discharge groove.

[0009] Furthermore, each blade has an arc-shaped structure, and when multiple blades are closed, they can wrap around the outside of the screw, protecting the holding trough and the discharge trough from being filled and blocked by soil when the device is inserted into the ground.

[0010] Furthermore, the inner side of the blade is an inclined surface, and the thickness gradually decreases from the connection end with the ear plate toward the lower end, thereby reserving space at the lower end of the blade for setting a locking block, and gradually pushing the blade outward during the rising process of the locking block.

[0011] Furthermore, the diameter of the top plate is larger than the opening of the arc-shaped cover, which can prevent rainwater or other large debris from entering the hollow screw.

[0012] Furthermore, the ear plate and the blade are movably connected by a pin, and the blade can unfold outward with the pin as the center under the action of the locking block.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention uses an underground insertion method to directly inject the pesticide into the ground, avoiding pesticide residue and loss on the surface. The blades wrapped around the screw can prevent soil from entering and blocking the discharge chute when the screw is inserted into the ground. After the device is inserted into the ground, the unfolding of the blades can push away the surrounding soil to create space, ensuring that the pesticide flows out smoothly, effectively attracting pests within the range and improving the control effect.

[0015] This invention features an arc-shaped cover at the top, facilitating the addition of medication to the screw. A top plate above the arc-shaped cover prevents rainwater from directly entering the screw, ensuring the medication dries and is released gradually, extending its duration of effect and reducing the inconvenience of frequent medication additions. Furthermore, the arc-shaped cover prevents debris or large pieces of soil from entering and clogging the central hole of the screw, allowing for normal medication replenishment to the downward-facing container through the screw during subsequent use.

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0026] As attached Figure 1-7 As shown.

[0027] A device for controlling underground pests includes a screw 1, which is hollow. An arc-shaped cover 2 is provided at the upper end of the screw 1. A top plate 4 is installed inside the arc-shaped cover 2 and above the screw 1 via a bracket 3. The diameter of the top plate 4 is larger than the opening of the arc-shaped cover 2, which can prevent rainwater or other large debris from entering the hollow screw 1.

[0028] Multiple lugs 11 for connecting blades 5 are installed in the middle of the screw 1, as shown in the attached figure. Figure 4 As shown, the ear plate 11 and the blade 5 are movably connected by a pin; the screw 1 is divided into upper and lower parts with the ear plate 11 as the midpoint. The upper part is provided with a thread for connecting with the nut 8, while the lower part is a smooth rod.

[0029] As attached Figure 5 As shown, a set of lifting cylinders 7 on the outside of screw 1 is movably connected to the lower end of nut 8. A slot 71 is opened in the lifting cylinder 7 at the position corresponding to the ear plate 11. The slot 71 can make the lifting cylinder 7 rise and fall without the influence of the ear plate 11, and can prevent the lifting cylinder 7 from rotating with nut 8.

[0030] A protruding locking block 72 is provided at the lower end of the lifting cylinder 7. The inner side of the blade 5 is an inclined surface, and its thickness gradually decreases from the connection end with the ear plate 11 towards the lower end. Thus, when the locking block 72 is located at the lowest end of the screw 1, the blade 5 on the outer side of the screw 1 can remain in a retracted state, as shown in the attached figure. Figure 1 As shown.

[0031] When the device is inserted into the ground and the blade 5 needs to be unfolded, simply turn the nut 8 to raise the lifting cylinder 7, and the locking block 72 will rise accordingly, gradually pushing the blade 5 out to unfold it.

[0032] The device is designed to be easily inserted into the ground. An inverted cone 6 is provided at the bottom end of the screw 1. An annular holding groove 61 is provided around the outside of the screw 1 on the upper surface of the cone 6. Multiple discharge grooves 12 are provided at the lower end of the screw 1. The medicine inside the screw 1 can be discharged into the discharge groove 12 through the discharge groove 12.

[0033] A single blade 5 has an arc-shaped structure. When multiple blades 5 are closed, as shown in the attached figure... Figure 1 As shown, it can be wrapped around the outside of the screw 1, and when the device is inserted into the ground, it can protect the holding tank 61 and the discharge tank 12 from being filled and blocked by soil.

[0034] The usage process is as follows:

[0035] Keep the device attached Figure 1 As shown, the device is then inserted in the peony planting area, with each device spaced 3-5 meters apart, so that the medicine added in the screw 1 can work effectively to attract and kill pests.

[0036] After the device is inserted into the ground, medicine can be added into the screw 1 through the arc-shaped cover 2 at the top of the device. The medicine falls with the screw 1 and flows out from the discharge trough 12, accumulating on the holding trough 61. Then, the user holds the upper end of the screw 1 with one hand and the nut 8 with the other hand, and rotates the nut 8, so that the nut 8 drives the locking block 72 to rise through the lifting cylinder 7, causing the blades 5 on the outside of the screw 1 to unfold, exposing the medicine in the holding trough 61, and starting to exert its effect, attracting and killing pests.

[0037] The size of leaf 5 can be adjusted according to soil compaction to create a stable drug release space underground, ensuring that the drug can be evenly distributed within the space.

[0038] Subsequently, during daily use, when the drug at the bottom is consumed, the drug stored inside the screw 1 will be gradually replenished into the storage tank 61 at the bottom, so that the device can be used for a long time after one drug addition.

[0039] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
