Description

Technical Field

[0001] The utility model relates to the field of protecting the base of a tree trunk, and more specifically, to a device for preventing longhorn beetle larvae from damaging the base of a pecan tree trunk. Background Art

[0002] Pecan, also known as Carya illinoinensis, hickory nut, and longevity nut, is native to the United States and northern Mexico. It is one of the world-famous nut-bearing tree species, an important woody oil plant, and an excellent tree species for timber and greening. During the cultivation of pecan, it is often damaged by pests, among which longhorn beetles cause the greatest harm to pecan trees. Longhorn beetle larvae will bore in the branches, especially at the base of the tree trunk, damaging the area between the phloem and xylem, affecting the transportation of water and nutrients. Some longhorn beetle larvae will also damage the roots of pecan trees, and in severe cases, it will lead to the death of the whole tree. Therefore, during the cultivation of pecan trees, there is an urgent need for a device that can prevent longhorn beetle larvae from damaging the base of the tree trunk to protect the tree trunk.

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model. Example

[0021] See also Figure 1 , Figure 2 and Figure 4 As shown, a device for preventing longhorn beetle larvae from damaging the base of a thin-shelled pecan tree trunk comprises a first tile 1 and a second tile 2 attached to both sides of the tree trunk. The first tile 1 and the second tile 2 are C-shaped structures and are made of plastic, which can be deformed to a certain extent. First extension plates 101 are symmetrically arranged outwardly on both sides of the first tile 1, and second extension plates 201 are symmetrically arranged outwardly on both sides of the second tile 2. The first extension plate 101 and the second extension plate 201 are parallel. Fixing bolts 103 are symmetrically arranged on the surface of the first extension plate 101, and through holes 203 are symmetrically opened on the surface of the second extension plate 201. The fixing bolt 103 passes through the through hole 203, so that the first tile 1 and the second tile 2 can move to a certain extent. The end of the fixing bolt 103 is screwed with an adjusting nut 3, and the adjusting nut 3 is placed on the side of the second extension plate 201 away from the first extension plate 101. The surface of the fixing bolt 103 is sleeved with a spring 4, one side of the spring 4 contacts the surface of the second extension plate 201, and the other end of the spring 4 contacts the surface of the adjusting nut 3. The spring 4 always exerts an outward force on the adjusting nut 3, thereby causing the first tile 1 and the second tile 2 to have a force to approach each other. So that it is included in the surface of the trunk, and the wrapping force on the trunk is affected by the spring 4. When the trunk grows thicker, the first tile 1 and the second tile 2 can be separated and the spring 4 can be squeezed. The inner walls on both sides of the second tile 2 are extended outward with docking plates 202. The inner walls on both sides of the first tile 1 close to the second tile 2 are symmetrically provided with docking grooves 102 that are compatible with the docking plates 202. The docking plates 202 fill the gap between the first tile 1 and the second tile 2 to ensure that the device fully wraps the trunk. The docking plates 202 can be deformed after being squeezed.

[0022] Wherein, a lower lip plate 5 is arranged below the outer sides of the first tile plate 1 and the second tile plate 2. The lower lip plate 5 is placed on the ground surface to improve the installation stability of the device. The surface of the lower lip plate 5 is evenly provided with U-shaped installation grooves 501 which are open outward.

[0023] Please refer to Figure 1 and Figure 3 As shown, an embedding cylinder 6 penetrates through the inner side of the lower lip plate 5. The bottom of the embedding cylinder 6 is inserted into the soil. The top of the embedding cylinder 6 is open to facilitate filling insecticidal granules into the interior of the embedding cylinder 6. The interior of the embedding cylinder 6 is filled with insecticidal granules. The insecticidal granules can be phoxim granule agents or pesticides that are harmful to larvae but harmless to plants. A conical part 602 is arranged at the bottom of the embedding cylinder 6 to facilitate the insertion of the embedding cylinder 6 into the soil. A mesh part 601 is arranged on the surface of the embedding cylinder 6 so that the pesticides inside can diffuse into the soil.

[0024] Wherein, a sealing plug plate 7 is screwed and sealed at the top of the embedding cylinder 6 to seal the open top of the embedding cylinder 6. The sealing plug plate 7 is placed on the upper surface of the lower lip plate 5. The cross-sectional dimension of the sealing plug plate 7 is larger than that of the U-shaped installation groove 501. The stability of the tile plate can be improved by the insertion of the embedding cylinder 6, so that the lower lip plate 5 can fit on the ground surface to prevent harmful insects from entering the interior from the ground surface. A pull ring 701 is arranged at the top of the sealing plug plate 7.

[0025] Working principle: During use, the first tile plate 1 and the second tile plate 2 are respectively placed on both sides of the base of the tree trunk, and it is ensured that the lower lip plate 5 is placed on the ground surface. Then the first tile plate 1 and the second tile plate 2 are gradually moved closer, and the fixing bolt 103 penetrates through the through hole 203. At this time, the docking plate 202 will enter into the docking groove 102 to seal the gap between the first tile plate 1 and the second tile plate 2. Then a spring 4 is sleeved on the surface of the fixing bolt 103, and the adjusting nut 3 is screwed. Due to the elastic force of the spring 4, the adjusting nut 3 has an outward thrust to pull the first tile plate 1 and the second tile plate 2 closer to ensure their close fit with the tree trunk. When the tree trunk thickens, it will cause an outward extrusion on the first tile plate 1 and the second tile plate 2. At this time, the fixing bolt 103 can slide automatically to adapt to the fit with the tree trunk. While protecting the tree trunk, insecticidal granules can be filled into the interior of the embedding cylinder 6, passed through the U-shaped installation groove 501 and then inserted into the soil. At this time, the medicament can diffuse around the soil through the mesh part 601 to kill the larvae in the soil. The top of the embedding cylinder 6 is sealed by the sealing plug plate 7, and the control of the embedding cylinder 6 is realized through the pull ring 701 at the top.

[0026] The above is only the preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
