Description

Technical Field

[0001] This utility model relates to the field of yellow sticky trap hanging technology for aphid control, and in particular to an escape-proof yellow sticky trap hanging device for aphid control on pear trees. Background Technology

[0002] In the cultivation of pear trees, conventional control methods include manual removal, physical control, and chemical control. Aphids infesting pear trees are removed. Yellow sticky traps are simple insect traps used in fields, greenhouses, homes, and the wild. They mainly use insects' attraction to yellow to stick the insects.

[0003] In the process of controlling aphids on pear trees, yellow sticky traps are used to attract and kill aphids. Existing yellow sticky traps are suspended from pear tree branches by hooks. However, the hook-based suspension method is not stable enough, and the device is not securely fixed. It is easy to shake or even fall off when the wind blows, which affects the continuous killing effect on aphids. Moreover, when the surface of the yellow sticky trap is covered with aphids and debris, it needs to be replaced regularly. However, the existing device relies on hooks for binding and fixing, which requires repeated disassembly and rebinding, making the operation cumbersome and time-consuming, and cannot meet the needs of use. Therefore, an escape-proof yellow sticky trap suspension device for the control of aphids on pear trees is proposed to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a yellow sticky trap hanging device for the control of pear tree aphids to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A yellow sticky trap hanging device for controlling pear tree aphids includes a protective cylinder with several connecting posts at the top and a rain cover between the tops of the connecting posts for overall protection of the device.

[0007] The top of the rain cover is equipped with a suspension assembly for suspending the device;

[0008] The protective cylinder is equipped with a yellow plate mounting assembly extending to its bottom for supporting and mounting the yellow plate.

[0009] The bottom of the yellow board mounting assembly is provided with a tray assembly that extends to its inner side and engages with it, for bottom sealing and engagement.

[0010] Preferably, the suspension assembly includes a hook, which is fixedly installed on the top of the rain cover. An extension hook extending to the outside of the hook is movably installed inside the hook. A return spring is fixedly installed and connected to one end of the extension hook inside the hook. A push rod is fixedly installed on the outside of the extension hook.

[0011] Preferably, the yellow board installation assembly includes a connecting sleeve, which is threaded inside the protective cylinder and extends to its bottom. A support cylinder is fixedly connected to the bottom of the connecting sleeve. A plurality of insect guide tubes, which are distributed in a ring and are connected to the outside of the support cylinder, are fixedly installed inside the support cylinder. A plurality of positioning posts, which are distributed in a ring and are connected in a ring, are fixedly installed on the top of the connecting sleeve. A ring-shaped yellow board is movably installed between the plurality of positioning posts.

[0012] Preferably, the pallet assembly includes a pallet, which is movably mounted below the support cylinder. An extension cylinder extending into the support cylinder is fixedly connected to the top of the pallet. A locking post that engages with the support cylinder is fixedly installed on the outer side of the extension cylinder. A groove is provided at the bottom of the pallet, and a handle is fixedly installed inside the groove.

[0013] Preferably, the protective cylinder has a transparent structure design, the outer side of the connecting sleeve has an external thread, the inner side of the protective cylinder has an internal thread that matches the connecting sleeve, and the diameter of the insect guide tube decreases from the outside to the inside.

[0014] Preferably, a bait groove is provided on the inner side of the extension tube.

[0015] Preferably, the side wall of the support cylinder is provided with a movable hole that matches the movement trajectory of the locking post, the bottom of the support cylinder is provided with an embedding hole that matches the locking post and communicates with the movable hole, and the side wall of the support cylinder is provided with a locking hole that communicates with the movable hole and matches the locking post.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This yellow sticky trap for aphid control on pear trees features a locking mechanism formed by a hook in the suspension assembly, along with an internal extension hook, return spring, and push rod. In its natural state, the extension hook extends outward under the force of the return spring. When the device is hung on a pear tree branch, the extension hook engages with the branch surface, increasing the contact area and friction, effectively preventing the device from falling off due to wind. To adjust the suspension position, simply push the push rod to retract the extension hook back into the hook. This convenient operation significantly improves the device's stability on branches of varying thicknesses, solving the problems of loosening and falling off with traditional hook-based suspension systems.

[0018] This pear tree aphid control device features an escape-proof yellow sticky trap. The yellow sticky trap's mounting assembly is connected via an external thread that mates with the internal thread of a protective cylinder. The mounting assembly and the support plate assembly are interlocked, facilitating easy installation or disassembly. The annular yellow sticky trap is horizontally mounted on top of the mounting assembly via a positioning post, ensuring stable positioning. To replace a trap covered in aphids, simply rotate the support cylinder to detach the mounting assembly from the protective cylinder and remove the annular trap. This solves the problem of time-consuming and laborious replacements caused by traditional devices with hooks. When bait needs to be placed, simply use the handle at the bottom of the support plate to disengage the interlocking post from the interlocking hole, movable hole, and embedding hole, detaching the support plate from the support cylinder and allowing bait to be placed, further enhancing the attraction to aphids. The insect guide tube inside the support cylinder guides aphids towards the yellow sticky trap, effectively improving the sustainability and efficiency of aphid trapping. Attached Figure Description

[0030] Example

[0031] like Figures 1 to 6 As shown, this utility model provides a technical solution: a yellow sticky trap hanging device for the control of aphids on pear trees, including a protective tube 1. The protective tube 1 has a transparent structure design, which makes it easy to directly observe the sticky insect state of the yellow sticky trap inside. Several connecting posts 2 are fixedly installed on the top of the protective tube 1, and a rain cover 3 is fixedly installed between the tops of the connecting posts 2. The pear tree planting environment is rainy, and traditional yellow sticky traps are easily diluted by rainwater or washed away by pests, resulting in the failure of the trapping and killing. The protective tube 1 and the rain cover 3 effectively protect the adhesive layer of the yellow sticky trap through physical shielding, extend its service life, and maintain its continuous trapping and killing ability.

[0032] A suspension assembly 4 is fixedly installed on the top of the rain cover 3. The suspension assembly 4 includes a hook 41, which is fixedly installed on the top of the rain cover 3. An extension hook 42 extending to the outside of the hook 41 is movably installed inside the hook 41. A return spring 43 is fixedly connected to one end of the extension hook 42 located inside the hook 41. A push rod 44 is fixedly installed on the outside of the extension hook 42. This yellow sticky trap for aphid control on pear trees forms a suspension device by setting the hook 41 in the suspension assembly 4 in conjunction with the internal extension hook 42, return spring 43 and push rod 44. With the locking structure, in its natural state, the extension hook 42 extends outward from the hook 41 under the elastic force of the return spring 43. When the device is hung on the pear tree branch through the hook 41, the extension hook 42 will be locked on the surface of the branch, increasing the contact area and friction with the branch, effectively preventing the device from falling off due to wind and shaking. When the suspension position needs to be adjusted, the extension hook 42 can be retracted into the hook 41 by pushing the push rod 44. The operation is convenient and significantly improves the fixing reliability of the device on branches of different thicknesses, solving the problems of easy loosening and falling off of traditional hook suspension.

[0033] Inside the protective cylinder 1, a yellow board mounting assembly 5 extending to its bottom is movably installed. The yellow board mounting assembly 5 includes a connecting sleeve 51, which is threaded inside the protective cylinder 1 and extends to its bottom. The connecting sleeve 51 has external threads on its outer side, and the protective cylinder 1 has internal threads that are compatible with the connecting sleeve 51. A support cylinder 52 is fixedly connected to the bottom of the connecting sleeve 51. Inside the support cylinder 52, several insect guide tubes 53 are fixedly installed, arranged in a ring and equidistantly, and connected to its outer side. The diameter of the insect guide tubes 53 decreases from the outside to the inside. After being attracted, aphids will move along the narrow inner diameter of the insect guide tubes 53 towards the center. The pipe diameter decreases from large to small to prevent aphids from escaping. Several positioning posts 54 are fixedly installed on the top of the connecting sleeve 51 and are distributed in a ring at equal intervals. A ring-shaped yellow plate 55 is movably installed between the positioning posts 54. This yellow plate suspension device for aphid control in pear trees ensures the stability of the yellow plate by setting the ring-shaped yellow plate 55 in the yellow plate installation component 5 to be horizontally installed on the top of the connecting sleeve 51 through the positioning posts 54. When it is necessary to replace the yellow plate covered with aphids, the connecting sleeve 51 and the protective cylinder 1 can be separated by rotating the support cylinder 52 to remove the ring-shaped yellow plate 55. This solves the problem of time-consuming and laborious replacement caused by the hook binding of traditional devices.

[0034] The bottom of the yellow board mounting assembly 5 is movably mounted with a tray assembly 6 extending to and engaging with it. The tray assembly 6 includes a tray 61, which is movably mounted below the support cylinder 52. The top of the tray 61 is fixedly connected to an extension cylinder 62 extending into the support cylinder 52. The inner side of the extension cylinder 62 has a bait groove 621 for placing bait to enhance its attraction to aphids. The outer side of the extension cylinder 62 has a locking post 63 that engages with the support cylinder 52. The side wall of the support cylinder 52 has a movable hole 631 that matches the movement trajectory of the locking post 63. The bottom of the support cylinder 52 has a hole that matches the locking post 63 and communicates with the movable hole 631. The support cylinder 52 has an insertion hole 632, and the side wall of the support cylinder 52 has an engagement hole 633 that communicates with the movable hole 631 and is adapted to the engagement post 63. The bottom of the tray 61 has a groove 64, and a handle 65 is fixedly installed inside the groove 64. By setting the tray assembly 6, the engagement post 63 can be withdrawn from the engagement hole 633, the movable hole 631 and the insertion hole 632 by controlling the handle 65 at the bottom of the tray 61. The tray 61 is then separated from the support cylinder 52 and bait can be placed, which further enhances the attraction to aphids. The insect guide tube 53 inside the support cylinder 52 can guide aphids to crawl towards the yellow sticky trap, which effectively improves the sustainability and efficiency of aphid trapping.

[0035] The working process of this utility model:

[0036] Step 1, suspension and fixation via suspension assembly 4: Hang hook 41 on the target branch of the pear tree, push push rod 44 to make extension hook 42 retract into hook 41 against the elastic force of return spring 43 until hook 41 is hung on the branch, release push rod 44, under the elastic force of return spring 43, extension hook 42 automatically pops out and locks on the outside of the branch, forming a stable suspension structure;

[0037] Step 2: Place the annular yellow plate 55 horizontally between the positioning posts 54 on the top of the connecting sleeve 51, ensuring that the edge of the yellow plate fits against the positioning posts 54; align the external thread at the bottom of the connecting sleeve 51 with the internal thread inside the protective cylinder 1, and rotate the connecting sleeve 51 clockwise to screw it into the protective cylinder 1 and make it tightly connected to the protective cylinder 1; then align the extension tube 62 at the top of the support plate 61 with the bottom opening of the support cylinder 52, press the support plate 61 upward, and let the locking post 63 on the outside of the extension tube 62 slide into the movable hole 631 along the embedding hole 632 on the side wall of the support cylinder 52 until the locking post 63 enters the embedding hole 632 at the bottom of the support cylinder 52 and engages. At this time, the support plate 61 is fixed to the support cylinder 52 by the locking post 63, completing the closed structure of the device and preventing pear aphids from escaping;

[0038] Step 3: The bait (such as sugar water or pheromones) in the bait groove 621 at the top of the tray 61 will release an odor to attract aphids. The aphids crawl along the insect guide tube 53 on the side wall of the support tube 52 into the protective tube 1, and are eventually stuck by the sticky insect glue on the surface of the yellow board, unable to escape, thus achieving escape prevention and trapping. When the yellow board is full of aphids and needs to be replaced, rotate the connecting sleeve 51 counterclockwise to unscrew it from the inside of the protective tube 1, and you can take out the ring yellow board 55 full of aphids and replace it with a new yellow board. Hold the handle 65 at the bottom of the tray 61, push it upward and rotate it, and the locking post 63 will exit from the locking hole 633 and move along the movable hole 631 to the embedding hole 632 and move downward. The tray 61 can then be separated from the support tube 52, making it convenient for the user to add aphid bait.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
