Furthermore, in the context, it should also be understood that when it is mentioned that an element is formed "upper" or "lower" of another element, it can not only be formed directly "upper" or "lower" of the other element, but also indirectly "upper" or "lower" of the other element through an intermediate element.
[0039] Figure 1 This diagram schematically illustrates the usage state of an insect-proof net according to one embodiment of the present invention. Figure 2 This schematic diagram illustrates the unfolded view of an insect-proof net according to one embodiment of the present invention, as shown below. Figure 1 , 2 As shown, the present invention provides a retractable and adjustable insect-proof net, comprising:
[0040] Main pole 10, multiple secondary poles 20, and netting 30;
[0041] The main rod 10 is located at one end of the mesh fabric 30, and multiple secondary rods 20 are located on the surface of the mesh fabric 30, with the multiple secondary rods 20 spaced apart and arranged in parallel.
[0042] The main pole 10 and the secondary pole 20 are arranged in parallel to each other. The mesh 30 is made of flexible material and surrounds the main pole 10 with the main pole 10 as the center.
[0043] The secondary pole 20 is made of flexible material, and its two ends are used to insert into the soil to support the netting 30, which is used to cover the tobacco seedlings and prevent insects from passing through.
[0044] This setup allows for water and air permeability through the mesh 30, ensuring a suitable growing environment for the tobacco seedlings. At the same time, the mesh 30 prevents insects from passing through, effectively avoiding the transfer of viruses carried by insects to the tobacco seedlings.
[0045] Meanwhile, the auxiliary pole 20 is set parallel to the main pole 10, and one end of the netting 30 is connected to the main pole 10, so that the netting 30 can be wrapped around the main pole 10 with the main pole 10 as the center for storage. When in use, the netting 30 is pulled out and supported by inserting the two ends of the auxiliary pole 20 into the soil to cover the tobacco seedlings. After use, the netting 30 is wrapped around the main pole 10 for storage, so that the device can be recycled and the cost is greatly reduced.
[0046] Furthermore, the lengths of the main stem 10 and the secondary stem 20 are adjustable. During the seedling stage of flue-cured tobacco seedlings, their height will increase as they grow, and the height of flue-cured tobacco seedlings varies at each seedling stage. At this time, the height at which the net cloth 30 is raised can be adjusted by adjusting the lengths of the main stem 10 and the secondary stem 20, thereby matching flue-cured tobacco seedlings of different heights and improving its applicability.
[0047] Furthermore, Figure 3 A schematic diagram illustrating the structure of the secondary rod in the first embodiment of this utility model is shown below. Figure 3 As shown:
[0048] In the first embodiment of this utility model, the auxiliary rod 20 is detachably connected to the mesh fabric 30. The auxiliary rod 20 includes a first rod body 201 and a second rod body 202. The first rod body 201 and the second rod body 202 are detachably connected to clamp and release the mesh fabric 30.
[0049] Specifically, the first rod body 201 includes a first fixed rod 2011 and at least one first telescopic rod 2012, the first telescopic rod 2012 extending into the first fixed rod 2011 and slidably connected to the first fixed rod 2011;
[0050] The second rod 202 includes a second fixed rod 2021 and at least one second telescopic rod 2022, wherein the second telescopic rod 2022 extends into the second fixed rod 2021 and is slidably connected to the second fixed rod 2021;
[0051] When the first rod 201 is connected to the second rod 202, the first fixed rod 2011 is connected to the second telescopic rod 2022, and the second fixed rod 2021 is connected to the first telescopic rod 2012.
[0052] With this setup, when it is necessary to cover taller tobacco seedlings, the lengths of the first telescopic rod 2012 and the second telescopic rod 2022 can be increased by extending the first telescopic rod 2012 outward relative to the first fixed rod 2011 and the second telescopic rod 2022 outward relative to the second fixed rod 2021. As a result, when the two rods clamp the mesh 30, an arched shape formed by the mesh 30 with a higher height is obtained. Conversely, the first telescopic rod 2012 and the second telescopic rod 2022 can be retracted to shorten the lengths of the first rod 201 and the second rod 202, thereby reducing the height of the arched shape formed by the mesh 30.
[0053] Since the first telescopic rod 2012 extends into the first fixed rod 2011, the diameter of the first telescopic rod 2012 is smaller than that of the first fixed rod 2011. Similarly, the diameter of the second telescopic rod 2022 is smaller than that of the second fixed rod 2021. Therefore, in order to ensure that the first rod 201 and the second rod 202 can fit together completely, when the first rod 201 and the second rod 202 are connected, the first telescopic rod 2012 needs to be fitted with the second fixed rod 2021, and the second telescopic rod 2022 needs to be fitted with the first fixed rod 2011, thus achieving the clamping of the mesh fabric 30.
[0054] The connection between the first rod 201 and the second rod 202 can be set as a magnetic connection, or it can be set as other structures that can achieve the connection.
[0055] Furthermore, Figure 4 This diagram schematically illustrates the structure of the first rod in one embodiment of the present invention. Figure 5 This schematic diagram illustrates the structure of the second rod in one embodiment of the present invention, as shown below. Figure 4 , 5 As shown:
[0056] A protruding first limiting block 20121 is provided on the side wall of the first telescopic rod 2012. The first limiting block 20121 is located near the end of the first telescopic rod 2012. A first sliding groove 20111 and a first limiting groove 20112 are provided on the side wall of the first fixed rod 2011. The first sliding groove 20111 extends a certain distance from one end of the first fixed rod 2011 to the other end. The first limiting groove 20112 is located on the side of the first sliding groove 20111 and communicates with the first sliding groove 20111. The first limiting groove 20112 has the same shape and size as the first limiting block 20121.
[0057] When the first telescopic rod 2012 extends into the first fixed rod 2011, the first limiting block 20121 is located in the first sliding groove 20111 and moves relative to the first sliding groove 20111 as the first telescopic rod 2012 moves. When the first limiting block 20121 moves to the position corresponding to the first limiting groove 20112, the first telescopic rod 2012 is rotated so that the first limiting block 20121 is located in the first limiting groove 20112, thereby restricting the movement of the first telescopic rod 2012, fixing the length of the first rod 201, and preventing the length from decreasing due to external factors, which would reduce the height of the arch formed by the net 30 and would not affect the growth of the tobacco seedlings.
[0058] The second rod 202 has the same structure as the first rod 201, and it can also achieve length locking.
[0059] Furthermore, Figure 6This schematic diagram illustrates the structure of the secondary rod in the second embodiment of the present invention, as shown below. Figure 6 As shown:
[0060] In the second embodiment of this utility model, the auxiliary rod 20 is fixedly connected to the mesh 30.
[0061] Specifically, the auxiliary rod 20 includes a third fixed rod 203 and a third telescopic rod 204. The third telescopic rod 204 extends into the third fixed rod 203 and is slidably connected to the third fixed rod 203. When the third telescopic rod 204 moves away from the third fixed rod 203 to the maximum distance, the mesh 30 is connected to the side walls of the third fixed rod 203 and the third telescopic rod 204 respectively.
[0062] A first groove 2031 is provided on the side wall of the third fixed rod 203, and the first groove 2031 is used for the mesh cloth on the third telescopic rod 204 to pass through.
[0063] Since the mesh 30 is connected to the side wall of the maximum length of the auxiliary rod 20, when the third telescopic rod 204 extends into the third fixed rod 203, part of the mesh 30 will inevitably be squeezed and folded inside the third fixed rod 203, affecting the sliding of the third telescopic rod 204 relative to the third fixed rod 203 and damaging the mesh 30. Therefore, a first groove 2031 is provided on the third fixed rod 203. When the third telescopic rod 204 retracts into the third fixed rod 203, the mesh 30 on the side wall of the portion of the third telescopic rod 204 located inside the third fixed rod 203 can be folded into the first groove 2031 and can extend through the first groove 2031 without affecting the normal use of the mesh 30 and avoiding damage to the mesh 30.
[0064] Furthermore, the first groove 2031 is located on the side of the area where the third fixing rod 203 connects to the mesh 30.
[0065] Furthermore, such as Figure 5 As shown, a second sliding groove 2032 and a second limiting groove 2033 are provided on the side wall of the third fixed rod 203. The second sliding groove 2032 extends a certain distance from one end of the third fixed rod 203 to the other end. The second limiting groove 2033 is provided on the side of the second sliding groove 2032 and is connected to the second sliding groove 2032. A protruding second limiting block 2041 is provided on the side wall of the third telescopic rod 204. The second limiting block 2041 is located near one end of the third telescopic rod 204.
[0066] When the third telescopic rod 204 extends into the third fixed rod 203, the second limiting block 2041 is located in the second sliding groove 2032. When the third telescopic rod 204 moves away from the third fixed rod 203 to the maximum distance, the third telescopic rod 204 is rotated so that the second limiting block 2041 is located in the second limiting groove 2033, thereby fixing the length of the auxiliary rod 20.
[0067] Furthermore, the second groove 2032 is disposed on the side of the first groove 2031.
[0068] Furthermore, the length of the main rod 10 is adjustable, and its structure is the same as that of the secondary rod 20, consisting of a fourth fixed rod (not shown in the figure) and a fourth telescopic rod (not shown in the figure).
[0069] Furthermore, a magnet is provided on the side wall of the main rod 10. When the netting 30 is completely pulled out from the main rod 10 and its length is still insufficient, the main rod 10 of another insect net can be attached to the main rod 10 to achieve splicing and use to increase the overall length.
[0070] Furthermore, multiple through holes (not shown in the figure) are evenly arranged on the surface of the mesh 30. The diameter of the through holes ranges from 60 mesh to 40 mesh, that is, 0.25-0.425 mm. At this diameter, the through holes can prevent insects from passing through and prevent the tobacco seedlings from being contaminated with viruses from insects.
[0071] Furthermore, the netting 30 is connected in the area between the two ends of the main pole 10 and the area between the two ends of the secondary pole 20. When the two ends of the main pole 10 and the secondary pole 20 are inserted into the soil, the netting 30 is buried in the soil at the same time, avoiding gaps between the netting 30 and the soil surface, thereby effectively preventing insects from entering the covered space of the netting 30 from the bottom and fully protecting the flue-cured tobacco seedlings inside.
[0072] In summary, through the solution of this utility model, when the insect-proof net is in use, the net cloth 30 is pulled out from the main pole 10 to cover the tobacco seedlings. After use, the net cloth 30 can be wrapped around the main pole 10 for storage, realizing the recycling of the insect-proof net and reducing costs. At the same time, the lengths of the main pole 10 and the auxiliary pole 20 are adjustable, which can be applied to tobacco seedlings of different heights or different growth stages, improving the applicability of this device.
[0073] The above description is merely a preferred embodiment of this application. Those skilled in the art should understand that the scope of disclosure in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
