[0038] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present utility model, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0039] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] As for the pest control device in the preferred embodiment of the utility model, its purpose is to solve or improve the pest problem of trees by means of physical isolation and capture.

[0042] The technical solution in the utility model is proposed because the inventor has found after long-term observation that insects living on trees mostly travel back and forth between trees and the ground in order to hatch the next generation, absorb nutrients, and survive the winter. Considering this, if a corresponding device is set on the insect's round-trip path to block the insect's passage path or directly capture the insect, the problem of tree diseases and insect pests can be fundamentally solved.

[0043] Based on this, the present invention proposes a novel disease and insect pest control device. As follows, the specific concepts and schemes in the present invention are further introduced through specific embodiments.

[0044] Example:

[0045] See also Figure 1~Figure 4 The pest control device for trees in the preferred embodiment of the utility model comprises a fixed tube 1 and an insect repellent cover 2 arranged on the outer periphery of the fixed tube 1 .

[0046] Specifically, the fixing cylinder 1 in the preferred embodiment is as follows Figure 1 As shown in (dashed area), it includes a cylindrical body 101, which is used to be sleeved on the outer circumference of the trunk and realize the fixation of the device.

[0047] Considering the height of the tree and the limitation of the branches, the cylinder 101 cannot be set in an axial sleeve manner, so in the preferred embodiment, the cylinder 101 is rolled into a cylinder in a circumferentially wrapped manner. That is to say, before the installation is completed, the cylinder 101 is actually a sheet structure or a curled arc structure, and is formed by attaching it to the surface of the trunk 3 and then curling it into a cylinder.

[0048] Of course, the cylinder 101 in the preferred embodiment may also be preferably assembled from a plurality of arc-shaped structures along the circumferential direction, for example, it can be regarded as being assembled from two arc-shaped plates that are broken into two parts by a complete cylinder.

[0049] In more detail, in order to realize the molding and fixing of the cylinder 101 , a first locking piece 104 is provided at the joint of the corresponding cylinder 101 , so as to realize the locking of the cylinder 101 after molding, and prevent the cylinder 101 from sliding down or falling off the trunk 3 .

[0050] In actual arrangement, the first locking member 104 is preferably arranged to extend along the length direction at the joint; or, a plurality of first locking members 104 are arranged at intervals in the length direction at the joint, for example Figure 1 The 3 shown in .

[0051] The locking members continuously arranged along the length direction may be adhesive members arranged at the corresponding joints, such as Velcro. By changing the adhesive positions, the inner diameter of the cylinder 101 can be adjusted accordingly to accommodate tree trunks 3 with different outer diameters.

[0052] For the multiple locking members arranged at intervals in the length direction, they are preferably locks, snaps or similar locking members, which usually include a movable part and a fixed part, which are respectively arranged on the surfaces on both sides of the seam of the cylinder 101. Through the matching of the movable part and the fixed part, a fixed connection at the seam of the cylinder 101 is achieved, thereby achieving the molding of the cylinder 101.

[0053] Of course, it can be understood that in addition to the above-mentioned locking methods, the locking of the joint of the cylinder 101 can also be carried out in other ways, such as magnetic fixation, strap fixation, etc., or a number of hoops, straps, etc. arranged circumferentially on the outer periphery of the cylinder 101. As long as the connection between the two sides of the seam of the cylinder 101 can be achieved, it will not be elaborated here.

[0054] More preferably, considering that the outer peripheral surface of the trunk 3 is not a standard cylindrical shape, and the growth characteristics of the trunk 3 are usually thick at the bottom and thin at the top, in actual setting, the cylinder 101 is preferably in a variable diameter form, and its outer diameter increases from the top to the bottom. Such a setting can better achieve the fit between the cylinder 101 and the surface of the trunk, and improve the tightness between the fixed cylinder 1 and the trunk after it is set.

[0055] In more detail, in order to achieve a close fit between the cylinder 101 and the trunk 3 and avoid forming a path for insects to pass through between the cylinder 101 and the trunk 3, an elastic sealing layer 103 is preferably provided on the inner circumferential wall surface of the cylinder 101, such as Figure 3 as shown in .

[0056] During the growth of the tree, the outer diameter of the trunk 3 will gradually increase. At this time, if the cylinder 101 is rigidly arranged on the outer periphery of the trunk 3, it will inevitably affect the normal growth of the tree or produce a local abnormal protrusion. At this time, based on the arrangement of the elastic sealing layer 103, on the one hand, the gap between the cylinder 101 and the trunk 3 can be filled, and on the other hand, it can adapt to the subsequent growth of the tree, that is, after the trunk 3 becomes thicker, the thickness of the elastic sealing layer 103 can be compressed within a certain range, so as not to affect the normal growth of the trunk 3.

[0057] In actual setting, the elastic sealing layer 103 can be formed in a variety of ways, such as filling foam glue in the gap between the cylinder 101 and the trunk 3 after the cylinder 101 is rolled up; or, the elastic sealing layer 103 is an elastic pad attached to the inner wall surface of the cylinder 101, such as a rubber pad, based on the elastic compression deformation of the elastic pad itself, which can complete the setting function of the elastic sealing layer 103.

[0058] Furthermore, a limited installation groove 102 is provided along the circumferential direction on the outer circumference of the cylinder 101 for corresponding embedding and installation of the insect repellent cover 2 .

[0059] In a preferred embodiment, the position-limiting installation groove 102 is made of a material with a certain bending ability or is directly opened on the outer peripheral surface of the cylinder 101, and is preferably arranged at the end of the cylinder 101, such as the top and / or the bottom. By setting the position-limiting installation groove 102, an insect repellent cover 2 can be correspondingly arranged at the top and / or the bottom of the cylinder 101.

[0060] In more detail, similar to the molding process of the cylinder 101 in the preferred embodiment, the limiting installation groove 102 in the preferred embodiment is also completed in the annular arrangement during the curling molding process of the cylinder 101, and it is further preferably formed with two limiting portions spaced apart in the length direction of the cylinder 101, such as Figure 3 As shown in FIG. , the inner peripheral edge of the insect repellent cover 2 is just embedded in the gap between the two limiting parts.

[0061] In order to avoid interference of the limit installation groove 102 with the seam when the cylinder 101 is formed, at least one end of the limit installation groove 102 is preferably at a certain distance from the seam, that is, the limit installation groove 102 does not form a closed ring in the annular direction. This setting is intended to ensure that the position of the seam can be switched in the annular direction, thereby adjusting the inner diameter of the cylinder 101.

[0062] However, the above-mentioned setting of the position-limiting installation groove 102 results in that after it matches the inner periphery of the insect-repellent cover 2, there is a section of the cover body 201 that does not match the position-limiting installation groove 102, which is equivalent to the inner periphery of the cover body 201 directly facing the outer periphery of the cylinder body 101; in this regard, in actual setting, it is preferred to provide a blocking member at the part of the insect-repellent cover 2 that is not embedded in the position-limiting installation groove 102, so as to block the gap between the inner periphery of the insect-repellent cover 2 and the cylinder body 101. In actual setting, the blocking member is preferably a rubber strip or a rubber belt with a certain elastic deformation ability.

[0063] In addition, in a specific configuration, the limiting installation groove 102 is fixedly connected to the cylinder body 101, or is detachably connected thereto.

[0064] In a specific preferred embodiment, the limiting installation groove 102 is arranged on the top of the cylinder 101 . At this time, after the setting of the insect-repellent cover 2 is completed, the main body of the cylinder 101 is covered under the insect-repellent cover 2 .

[0065] In another specific preferred embodiment, limited mounting grooves 102 are respectively provided at the top and bottom of the cylinder 101, and insect-repellent covers 2 are respectively provided in the two limited mounting grooves 102. At this time, two insect-repellent covers 2 are provided in the length direction of the cylinder 101 to extend the insect-repellent path of the device and enhance the insect-repellent effect of the device.

[0066] More preferably, when insect repellent covers 2 are respectively provided at both ends of the cylinder 101, the outer diameter of the upper insect repellent cover 2 is preferably greater than the outer diameter of the lower insect repellent cover 2, so that the lower insect repellent cover 2 is always covered by another insect repellent cover 2 in the vertical direction. In this way, the upper insect repellent cover 2 can effectively block fallen objects and rainwater on the trees, providing protection for the lower insect repellent cover 2; at the same time, the lower insect repellent cover 2 can also effectively block back splashing water from the ground, protecting the bottom adhesive layer 203 of the upper insect repellent cover 2.

[0067] Furthermore, for the insect-repellent cover 2 in the preferred embodiment, it is preferably formed by a fan-shaped plate body connected end to end on the outer periphery of the fixed cylinder 1, and its setting form is similar to the molding of the cylinder body 101, but the formed insect-repellent cover 2 is not cylindrical, but in the form of a flat circular ring. The inner diameter of the circular ring structure just corresponds to the outer diameter of the groove bottom of the limiting installation groove 102, so that the insect-repellent cover 2 can be just embedded in the limiting installation groove 102 in the inner circumferential direction, and the limiting installation groove 102 realizes the support and axial limitation of the insect-repellent cover 2 on the outer periphery of the fixed cylinder 1.

[0068] It can be understood that, in actual configuration, the insect repellent cover 2 can be formed by connecting a single fan-shaped plate at both ends and then enclosing it, or it can be formed by splicing a plurality of fan-shaped plates in sequence along the circumferential direction.

[0069] In more detail, the insect repellent cover 2 includes a cover body 201 in a circular ring shape, and the cover body 201 further has an inverted disc structure, such as Figure 2 As shown in , at this time, the outer contour of the top surface of the cover body 201 continuously slopes downward from the middle to the periphery, forming a certain slope on the top surface of the cover body 201 to avoid water accumulation on the cover body 201 and facilitate rainwater to flow down quickly.

[0070] Furthermore, an adhesive layer 203 is provided on the bottom side wall surface of the cover body 201 along the circumferential direction. The adhesive layer 203 is preferably in a circumferentially closed form and does not provide any crawling path.

[0071] It is not difficult to find that the “inverted disc” design of the cover body 201 can also provide certain lateral protection for the adhesive layer 203 disposed on the bottom surface thereof, thereby avoiding contamination and damage to the adhesive layer 203 .

[0072] In actual setting, the adhesive layer 203 is preferably set on the bottom surface of the cover body 201 in a pasting manner; or, the adhesive layer 203 is formed on the bottom surface of the cover body 201 by periodic coating. For the former, the setting form of the adhesive layer 203 is similar to "double-sided tape", one side is bonded to the bottom surface of the cover body 201, and the other side is used as an adhesive layer for capturing insects. For the latter, the adhesive liquid is directly applied to the bottom surface of the cover body 201, and an adhesive layer for capturing onions is directly formed on the bottom surface of the cover body 201.

[0073] As for the adhesive layer 203, it can be replaced or repaired regularly as needed.

[0074] In addition, considering that most insects are more sensitive to yellow objects, in a preferred embodiment, the adhesive layer 203 is preferably set to yellow; or, the bottom surface of the cover body 201 is coated with a yellow coating, and then glue is coated on the yellow coating.

[0075] By using the adhesive layer 203 on the bottom surface of the cover body 201, the insects that crawl through the tree trunk 3 to the insect repellent cover 2 can be effectively adhered, thereby killing the insects and solving the problem of tree diseases and insect pests from the source.

[0076] Of course, it can be understood that since the cover body 201 is a fan-shaped sheet structure connected along the circumferential direction, a locking piece is also provided at the seam of the cover body 201, that is, Figure 1 The second locking member 202 is shown in FIG.

[0077] In terms of the setting form, the second locking member 202 can be the same as or different from the first locking member 104. It can be any form of an adhesive member, a locking member, a riveted member, or a magnetic member. It will not be elaborated here, as long as it can achieve locking and unlocking at the seam of the cover body 201.

[0078] Preferably, in actual setting, the inner diameters of the cylinder 101 and the cover 201 are adjustable through the control of the first locking member 104 and the second locking member 202 .

[0079] More preferably, in order to improve the assembly sealing between the cover body 201 and the limiting mounting groove 102, sealing strips are preferably arranged relatively in the limiting mounting groove 102, and the two sealing strips are both extended in the circumferential direction. After the cover body 201 is embedded in the limiting mounting groove 102 with an inner ring, they are arranged on both sides of the cover body 201 and tightly attached to the end faces of both sides of the cover body 201, thereby ensuring the sealing at the assembly position of the cover body 201 and the limiting mounting groove 102.

[0080] Based on the structural design of the pest control device in the above preferred embodiment, a structure such as Figure 4 The structure described in the embodiment utilizes the setting of the fixed tube 1 to realize the reliable setting of the insect repellent cover 2, and utilizes the setting of the insect repellent cover 2 to cut off the crawling path of the insects on the tree trunk 3, thereby achieving the purpose of physically controlling the problem of pests and diseases.

[0081] It is understandable that as the tree continues to grow, its trunk 3 will continue to thicken. When the trunk 3 becomes thicker and exceeds the compression range of the elastic sealing layer 103, the insect repellent cover 2 and the fixing tube 1 can be loosened accordingly, and the inner diameter of the two after being locked can be increased, or the device can be adjusted upward to the trunk 3, or replaced with a device of larger size. No further details will be given here.

[0082] The pest control device suitable for trees in the utility model has a simple structure and is easy to assemble and disassemble. It can be quickly set and adjusted on the tree trunk, physically cut off the path of insects traveling back and forth between the tree and the ground on the trunk, and can effectively capture insects from the ground, thereby solving or improving the problem of tree pest control from the root, avoiding the large-scale use of pesticides, protecting the environment, and improving the quality of tree crops. It has good practical value and application prospects.

[0083] It is easy for those skilled in the art to understand that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
