Description

Technical Field

[0001] This utility model relates to the field of pear tree insect control technology, and in particular to a pear tree insect control net cover that is easy to install and disassemble. Background Technology

[0002] Pear tree insect-proof netting, as an important agricultural protection tool, effectively blocks pests such as aphids and fruit borers from harming pear trees through physical isolation, thus protecting pear tree growth and fruit quality. It is widely used in orchard protection. In practical applications, pear tree insect-proof netting typically consists of the following components:

[0003] 1. The insect-proof netting is woven from materials such as nylon or polyethylene, which has good air permeability and light transmission. The mesh size is reasonably designed to block pests from entering without affecting the normal photosynthesis and ventilation of the pear tree.

[0004] 2. The supporting structure is generally composed of bamboo poles, steel pipes or plastic poles, etc., used to support the insect-proof netting and maintain a certain space between it and the pear tree to avoid the netting directly contacting the pear tree and affecting the tree's growth;

[0005] 3. Common fixing components include ground nails and ropes, which are used to fix the insect netting to the orchard ground or tree trunks to prevent it from being blown away or moved by the wind.

[0006] Currently, to effectively protect pear trees, fruit farmers use various types of insect-proof netting. Some farmers use integrated insect-proof netting that completely wraps the entire pear tree, providing comprehensive protection; others use modular insect-proof netting, which is spliced ​​together to protect the pear tree, making it easy to adjust to different tree shapes; still others choose simple hanging insect-proof netting, which is relatively easy to operate.

[0007] However, the above-mentioned implementation methods still have the following problems: In terms of installation and disassembly, existing insect-proof nets have complex structures, the installation process is cumbersome and requires multiple people to complete, and disassembly also consumes a lot of time and energy, seriously affecting the efficiency of daily orchard management. In terms of sealing, most insect-proof nets do not fit tightly against the tree trunk at the bottom, leaving large gaps, which allows pests to easily crawl into the net from the bottom, reducing the insect-proof effect and failing to meet the actual needs of pear tree protection. This application proposes a solution to this problem: designing a pear tree insect-proof net that is easy to install and disassemble and is equipped with a tightening mechanism. This insect-proof net can be quickly installed and disassembled, and the tightening mechanism ensures that the bottom of the net fits tightly against the tree trunk, effectively improving the protective performance. Utility Model Content

[0008] To address the shortcomings of existing technologies, this utility model provides a pear tree insect-proof net that is easy to install and disassemble. It solves the problems of existing insect-proof nets having complex structures, cumbersome installation processes that require multiple people to complete, and time and effort that are consumed during disassembly, which seriously affect the efficiency of daily orchard management. In terms of sealing, most insect-proof nets do not fit tightly to the tree trunk at the bottom, leaving large gaps that allow pests to easily enter the net from the bottom, reducing the insect-proof effect.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] An easy-to-install and disassemble insect-proof netting for pear trees includes a cover body with two zippers. A chain link is located at the bottom of the cover body, and a connecting tube is provided at the connecting end of the chain link. Two pressing blocks are movably sleeved inside the connecting tube. A return spring is fixedly connected to the opposing surfaces of the two pressing blocks, and a clamping block is fixedly connected to the opposing surfaces of the two pressing blocks. A set of connecting holes is provided through the bottom of the cover body, and all of the connecting holes are movably sleeved with the chain link.

[0011] Preferably, a connecting plate is fixedly connected inside the connecting tube, and both of the two return springs are fixedly connected to the connecting plate. Two slots are formed through the surface of the connecting plate, and the two slots are respectively engaged with two clamping blocks.

[0012] Preferably, each of the two pressing blocks has two limiting blocks fixedly connected to its annular side, and the inner wall of the connecting tube has two sets of limiting grooves, which are movably connected to the two sets of limiting blocks respectively.

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

[0014] 1. Pass the chain links through a set of connecting holes at the bottom of the cover. Tighten the chain links to ensure the bottom of the cover fits tightly against the pear tree trunk. Connect and fix the chain links to the two clamping blocks. The tight fit between the cover and the trunk prevents pests from entering through the gaps, reducing pest damage to the pear tree, protecting its growth and fruit quality. Furthermore, the fixing process ensures the cover is securely attached to the pear tree, preventing it from shifting or breaking due to wind or friction with the trunk, thus extending the cover's lifespan and providing continuous and stable protection for the pear tree.

[0015] 2. By pulling the connecting pipe, the chain links installed on it can be removed, disengaging it from the set of connecting holes at the lower end of the cover. If the cover is damaged or aged, the easy installation and disassembly design allows workers to easily remove it for repair or replacement, ensuring timely insect prevention. It also facilitates regular cleaning and maintenance of the cover, extending its service life. Attached Figure Description

[0022] This application provides a pear tree insect-proof net that is easy to install and disassemble. It effectively solves the problems of existing insect-proof nets, which are complex in structure, cumbersome in installation, require multiple people to complete, and consume a lot of time and energy to disassemble, seriously affecting the efficiency of daily orchard management. In terms of sealing, most insect-proof nets do not fit tightly to the tree trunk at the bottom, leaving large gaps that allow pests to easily enter the net from the bottom, reducing the insect-proof effect. This application designs a pear tree insect-proof net that is easy to install and disassemble and is equipped with a tightening mechanism. This insect-proof net can be quickly installed and disassembled, and the tightening mechanism ensures that the bottom of the net fits tightly to the tree trunk, effectively improving the protective performance.

[0023] Example

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the problems of existing insect-proof nets being complex in structure, cumbersome in installation, requiring multiple people to complete, and consuming a lot of time and effort during disassembly, which seriously affects the efficiency of daily orchard management. Regarding sealing, most insect-proof nets do not fit tightly against the tree trunk at the bottom, leaving large gaps that allow pests to easily enter the net from the bottom, reducing its insect-proof effect. The overall approach is as follows:

[0025] To address the problems existing in the prior art, this utility model provides a pear tree insect-proof net cover that is easy to install and disassemble. It includes a cover body 1, with two zippers 2 on the cover body 1. A chain link 4 is located at the bottom of the cover body 1, and a connecting tube 5 is provided at the connecting end of the chain link 4. Two pressing blocks 6 are movably sleeved inside the connecting tube 5. A return spring 10 is fixedly connected to the opposite face of each pressing block 6, and a clamping block 9 is fixedly connected to the opposite face of each pressing block 6. A set of connecting holes 3 is provided through the bottom of the cover body 1, and each set of connecting holes 3 is movably sleeved with the chain link 4. In use, the cover body 1 is unfolded and placed over the pear tree from the top, completely covering the pear tree with the cover body 1. Cover the pear tree and then zip up the zipper 2 to complete the installation. After installation, pass the chain link 4 through a set of connecting holes 3 at the lower end of the cover 1. Tighten the chain link 4 to make the lower end of the cover 1 fit tightly against the pear tree trunk. Connect and fix the chain link 4 to the two clamping blocks 9. The tight fit between the cover 1 and the trunk prevents pests from entering through the gap between the cover 1 and the trunk, reducing pest damage to the pear tree, protecting the growth of the pear tree and the quality of the fruit. Furthermore, the fixing allows the cover 1 to be better fixed to the pear tree, preventing it from shifting or breaking due to wind or friction with the trunk, extending the service life of the cover 1 and providing continuous and stable protection for the pear tree.

[0026] A connecting plate 11 is fixedly connected inside the connecting tube 5. Two return springs 10 are also fixedly connected to the connecting plate 11. Two slots 12 are formed through the surface of the connecting plate 11, and each slot 12 is movably engaged with one of the two clamping blocks 9. Two limiting blocks 8 are fixedly connected to the annular sides of each of the two pressing blocks 6. Two sets of limiting grooves 7 are formed on the inner wall of the connecting tube 5, and each set of limiting grooves 7 is movably connected to one of the two sets of limiting blocks 8. When disassembly is required, pressing the two pressing blocks 6 relative to each other will move the fixed clamping blocks 9 together, compressing the two clamping blocks 9. A return spring 10 is used, and at this time the two clamping blocks 9 are in an open state, so the chain link 4 can be taken out and the limiting fixation of it is opened. By pulling the connecting tube 5, the chain link 4 on it can be taken out, so that it is disengaged from the set of connecting holes 3 opened at the lower end of the cover 1. If the cover 1 is damaged or aged, the design that makes it easy to install and disassemble allows the staff to easily remove it for repair or replacement, so as to ensure the insect prevention effect in time. At the same time, it is also conducive to the regular cleaning and maintenance of the cover 1, extending its service life.

[0027] Among them, cover body 1: as the main component of the pear tree insect-proof net cover, it is used to cover the pear tree and form a physical protective barrier to block the invasion of pests. At the same time, its air permeability and light transmission can ensure that the normal growth and photosynthesis of the pear tree are not affected.

[0028] Zipper 2: Installed on the side of the cover 1, the net cover can be quickly opened and closed through the opening and closing operation, which facilitates the management of pear trees such as pruning and harvesting, and significantly improves the efficiency of installation and dismantling.

[0029] Connection hole 3: Provides an interface for connecting various components. Connectors can pass through to achieve stable assembly of components, making the insect net structure compact and ensuring the effective functioning of the overall protection.

[0030] Chain link 4: Used in conjunction with connecting hole 3, etc., to facilitate the connection and fixation between components, enhance the stability of the mesh cover structure, and facilitate the quick assembly and separation of components during installation and disassembly;

[0031] Connecting pipe 5: It plays a connecting and supporting role, connecting different components, ensuring the transmission of force, maintaining the overall structural strength of the mesh cover, and helping to achieve stable installation;

[0032] Pressing block 6: Pressing triggers the action of related components, working in conjunction with other components to achieve functions such as tightening and loosening, making it easy to adjust the net cover and make it fit the pear tree better;

[0033] Limiting groove 7: Restricts and guides the movement range of related components, ensures that components move on the predetermined track, prevents misalignment or detachment, and ensures the reliable function of the mesh cover;

[0034] Limiting block 8: Cooperates with limiting groove 7 to restrict the movement of components, play a positioning and fixing role, ensure that each component is installed in place, stabilize the mesh structure, and enhance the protective effect;

[0035] Clamping block 9: Used to clamp the tree trunk or other parts, and achieves a tight fit between the netting and the tree trunk or a stable connection between parts through clamping action, thereby improving sealing and stability;

[0036] Return spring 10: After the component is subjected to force, it provides a return force by its own elasticity, so that the component returns to its initial state, ensuring that the mesh cover functional component can be reused and maintain normal performance;

[0037] Connecting plate 11: As a basic platform for component connection, it provides multiple connection points to facilitate assembly with other components, distribute connection stress, and enhance the overall connection strength of the mesh cover;

[0038] Slot 12: Used to snap into corresponding components, enabling quick installation and positioning. It can be used with protrusions or blocks to ensure tight connection of components, prevent loosening, and improve the stability of the mesh cover structure.

[0039] Working principle:

[0040] During use, unfold the cover 1 and slide it over the pear tree from the top, completely covering the tree. Then, zip up the zipper 2 to complete the installation. After installation, thread the chain link 4 through the set of connecting holes 3 at the bottom of the cover 1. Tighten the chain link 4 to ensure a tight fit between the bottom of the cover 1 and the pear tree trunk. Connect and secure the chain link 4 to the two clamping blocks 9. This tight fit prevents pests from entering through the gap between the cover 1 and the trunk, reducing pest damage to the pear tree, protecting its growth and fruit quality. Furthermore, the secure mounting ensures the cover 1 is firmly fixed to the pear tree, preventing displacement or damage due to wind or friction with the trunk, thus extending its lifespan. The design provides continuous and stable protection for pear trees. When disassembly is required, pressing the two pressing blocks 6 will move the fixed clamping blocks 9 together, compressing the two return springs 10. At this time, the two clamping blocks 9 are in an open state, allowing the chain link 4 to be removed and its limiting fixation to be released. By pulling the connecting tube 5, the chain link 4 on it can be removed, disengaging it from the set of connecting holes 3 at the lower end of the cover 1. If the cover 1 is damaged or aged, the design that facilitates installation and disassembly allows workers to easily remove it for repair or replacement, ensuring timely insect prevention and facilitating regular cleaning and maintenance of the cover 1, thus extending its service life.

[0041] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
