Description

Technical Field

[0001] The invention relates to the technical field of orchard insect-proof fences, in particular to an insect-proof fence net for an orchard. Background Art

[0002] During the process of orchard planting and maintenance, fences are usually arranged around the orchard for physical protection of the orchard. However, ordinary fences are usually only used to prevent animal invasion or outside entry. Orchards are also often susceptible to insect pests during maintenance. When the orchard is seriously infested with insect pests, it will affect the growth of fruit trees and cause a reduction in fruit tree yield. Therefore, while carrying out internal pest control, corresponding external pest protection is also required. The pests that affect orchards are mainly herbivorous insects with poor flying ability, and their general flying height is only about two meters. Therefore, setting up insect-proof nets on orchard fences can effectively reduce the invasion of external pests.

[0003] However, most orchard pests have the characteristic of climbing upwards. After the pests fly and touch the fence net, they can often still crawl upwards along the fence net and eventually climb over the fence net, affecting the protective effect of the fence net. The existing treatment method is usually to further increase the height of the fence net or set up auxiliary protection structures such as electric grids, but this may lead to a large waste of materials and energy, increasing costs. There is also a kind of garden insect-proof fence net such as CN212867104U, which includes an insect-proof net and a plurality of columns. The insect-proof net is fitted with the rear side of the column, and the upper end of the insect-proof net is folded toward the front side of the column to form an insect-proof cavity with an opening facing downward, which can trap insects in the insect-proof cavity, thereby achieving obvious insect-proof effect and energy saving and environmental protection. However, this type of fence net usually has fences and protective nets that are independent structures. When they are laid out, they are generally transported and installed separately. The protective net needs to be cut on site and gradually fixed with cable ties. Whether it is to increase the height of the fence net, set up an electric grid, or an additional curled insect-proof cavity, the overall installation process is time-consuming and labor-intensive. At the same time, cable tie fixation easily leaves large gaps, and pests can easily pass through the gaps, affecting the installation and use of the insect-proof fence net. In view of this, in-depth research was conducted on the above-mentioned problems, which led to the creation of this case. Summary of the invention

[0004] The object of the present invention is to provide an insect-proof fence net for an orchard, so as to solve the problems of poor protection effect and inconvenient installation of the insect-proof fence net mentioned in the above background technology.

[0006] Preferably, the insect-proof bracket is arranged to fit the bottom arc of the inner-rolled cavity for placing insecticide attractants, and the insect-proof bracket is a detachable structure to facilitate internal cleaning.

[0007] By adopting the above technical solution, the additionally arranged insect-proof bracket can cooperate with the inner-rolled cavity to form an insect-proof trap. The inner-rolled cavity spirally rolls 360°, and the insects are trapped and killed in the insect-proof bracket of the inner-rolled cavity by utilizing the characteristics of insects climbing upwards and the lure of insecticides. The detachable insect-proof bracket can also facilitate the cleaning of insect corpses and the replacement of auxiliary insecticide supplies.

[0008] Preferably, a magnetic strip is attached to the inner side of the supporting roll plate, and the magnetic strip is evenly distributed along the arc of the inner wall of the inner roll cavity, and the top of the insect-proof net is fitted between the supporting roll plate and the magnetic strip.

[0009] By adopting the above technical solution and cooperating with the magnetic sticker strip, the insect-proof net can be stably attached along the inner wall of the spiral inward cavity to form a complete insect-proof trap, so that insects will climb along the insect-proof net and be trapped inside the inward cavity and cannot directly crawl into the orchard.

[0010] Preferably, the side ends of the fixed cross bar and the movable cross bar are both provided with guide limit blocks, and the outer edges of the guide limit blocks are limit fitting ends, and the limit fitting ends at the fixed cross bar and the movable cross bar are respectively limit fitted with the upper and lower ends of the fixed side fixed splints.

[0011] By adopting the above technical solution, when the fixed cross bar and the movable cross bar are respectively in the unfolded state at the upper and lower ends of the insect-proof net, the side fixed splints are pressed backwards to clamp the sides of the insect-proof net, and at the same time, the upper and lower ends of the side fixed splints respectively press against the limiting fitting ends of the guide limit blocks at the side ends of the fixed cross bar and the movable cross bar, so as to maintain the fixed columns, the fixed cross bar and the movable cross bar to form a stable overall supporting frame.

[0012] Preferably, a guide protrusion is protruding from the outer end of the guide limit block at the movable cross bar, and the guide protrusion forms an up and down sliding structure along the guide movable groove.

[0013] By adopting the above technical solution, the guiding protrusion cooperates with the guiding movable groove to stably guide the movable cross bar to drive the insect-proof net to be pulled down and laid.

[0014] Preferably, the underground positioning plate body comprises a positioning horizontal plate and an underground plug-in plate, the underground plug-in plate is located below the positioning horizontal plate, and the movable cross bar, the positioning horizontal plate and the underground plug-in plate are integrally welded structures; The surface of the positioning transverse plate is provided with fixing bolts, and the positioning transverse plate is connected and fixed to the fitting clamping plate at the lower end of the insect-proof net through the fixing bolts.

[0015] By adopting the above technical scheme, after the buried positioning plate is pulled down and arranged in conjunction with the movable cross bar, the movable cross bar and the buried positioning plate can be fixed and limited as a whole by the positioning cross plate in conjunction with the fixing bolts and the guide limit blocks. At the same time, the insect-proof net is embedded in the soil layer in conjunction with the buried plug plate, which can effectively avoid the appearance of gaps between the insect-proof net and the ground surface, thereby effectively preventing insects from entering.

[0016] Preferably, a side support column and a side support base plate are provided on the back of the fixed column, and the front ends of the side support column and the side support base plate are respectively integrated with a first movable axis and a second movable axis, and the fixed column, the side support column and the side support base plate form a triangular support structure as a whole.

[0017] By adopting the above technical solution, the overall installation stability of the device can be effectively improved by fixing the columns, the side support columns and the side support bottom plate to form an overall triangular support frame structure.

[0018] Preferably, movable through slots are provided at the upper and lower ends of the fixed column corresponding to the limiting connectors, and the limiting connectors penetrate the movable through slots to form a movable telescopic structure, and the first movable shaft and the second movable shaft are movably connected to adjacent limiting connectors respectively.

[0019] By adopting the above technical solution, when there is no need to install the side support columns and the side support base plate, the limiting connector can directly use the bolt structure to adjust and tighten the side fixed clamp through the limiting connector, and the movable limiting connector can be further coordinated with the movable installation of the side support column and the side support base plate by setting a movable limiting connector.

[0020] Preferably, the front ends of the side support columns and the side support base plates are provided with fitting movable blocks, and the fitting surfaces between the fitting movable blocks and the fixed columns are fitting arc surfaces, and the first movable axis and the second movable axis are eccentrically arranged with respect to the adjacent fitting arc surfaces, so that the limiting connecting piece and the side fixed splint are synchronously pulled backward by deflecting the side support columns and the side support base plates backward.

[0021] By adopting the above technical solution, the side support column and the side support base plate can be folded and stored at the side of the fixed column in cooperation with the rotating structure of the first movable axis and the second movable axis. When the side support column and the side support base plate are unfolded for use, due to the eccentric setting of the fitting arc surface and the axis line, the front end of the side support column and the side support base plate will be pushed away from the surface of the fixed column simultaneously, and the limiting connector connecting the first movable axis and the second movable axis will be pulled back synchronously, so that the side fixed splint will be pressed backward synchronously to clamp the side of the insect-proof net, which is convenient for rapid and coordinated adjustment of the layout.

[0024] Compared with the prior art, the beneficial effect of the present invention is that the insect-proof fence net for orchards has the following structural advantages: 1. The insect-proof net cooperates with the supporting coil plate to fold forward and spirally roll around to form an inner roll cavity. On the one hand, it can be used to store the insect-proof net in advance. When leaving the factory and transporting, the insect-proof net is directly stored in the inner roll cavity, which plays a protective role and is convenient for matching transfer. There is no need to adapt and cut during the later assembly, which is convenient for quick on-site installation and use. On the other hand, when in use, the characteristics of insects climbing upwards are used, and auxiliary insecticides such as attractants and insecticides are placed in the inner roll cavity with the insect-proof bracket to trap the insects to death in the inner roll cavity, so as to achieve the effect of insect prevention. The installation and use are safe and convenient, and the insect prevention effect is good; 2. While the fixed crossbar and the movable crossbar cooperate with the fixed columns to form the overall frame structure, the fixed crossbar and the movable crossbar can cooperate with the fitting plywood to fix the upper and lower ends of the insect-proof net respectively. In the initial state, the fixed crossbar and the movable crossbar are both located at the upper end of the fixed column, and the insect-proof net is stored in the inner roll cavity. The movable crossbar is pulled down along the guide movable groove, and the insect-proof net can be pulled out synchronously and quickly laid out on the surface of the guardrail body. While the overall frame structure can be quickly formed, the insect-proof net can be positioned on the side of the frame edge by fitting the plywood and cooperating with the side fixed plywood. No cable tie is required for fixing. The installation and layout are firm and convenient. It is embedded in the ground with the buried positioning plate for fixing, which effectively reduces the gaps at the edge of the insect-proof net, effectively isolates the invasion of pests, and improves the insect-proof effect. 3. A side support column and a side support bottom plate structure are provided to further cooperate for quick and stable installation and layout. During the installation and use of the fence net, the side support columns and the side support bottom plate can be folded and stored for easy transfer and transportation. When installed and used, the side support columns and the side support bottom plate cooperate with the fixed columns to form a stable triangular support structure, thereby improving the installation stability of the overall fence net. At the same time, the side support columns and the side support bottom plate are movably connected to the limiting connectors of the side fixed splints. When the side support columns and the side support bottom plate are deflected and unfolded, the side fixed splints can be driven to fit with the fixed columns through the active friction of the fitting arc surface, thereby clamping and fixing the insect-proof net while completing the frame support structure. It has good structural stability and coordination, is easy to install, and has a firm structure. BRIEF DESCRIPTION OF THE DRAWINGS
