Description

Technical Field

[0001] This utility model relates to the field of cowpea planting technology, specifically a split-type insect-proof net for green pest control in cowpea planting. Background Technology

[0002] Cowpeas are an annual crop belonging to the legume family. Traditional planting methods result in a high incidence of diseases and pests. Common diseases include root-knot nematode disease, powdery mildew, mosaic virus disease, and bacterial blight. Major pests include bean pod borer, thrips, American serpentine leafminer, and whitefly. To control cowpea diseases and pests, farmers often choose to spray various pesticides such as methamidophos, parathion, carbendazim, and thiophanate-methyl wettable powder to address the reduced yield caused by diseases and pests. However, pesticide residues inevitably remain in the cowpeas, thus reducing their food safety. Therefore, insect netting has become a particularly important green control tool.

[0003] Existing patent publication number CN218831482U discloses an insect-proof device for organic fruits and vegetables, belonging to the field of planting technology. The device includes a trellis and an insect-proof net. The net completely covers the top and sides of the trellis, with the bottom of the trellis inserted into the farmland. The lower end of the net is also located within the farmland, and the mesh size of the net is less than 29 meshes. This invention provides an insect-proof device that, by using an insect-proof net with a mesh size of less than 29 meshes, removes pests from the farmland before planting. The farmland is then sealed with the net, preventing the eggs of flea beetles, aphids, leaf miners, and other pests from escaping. This ensures that crops are protected from pests from sowing to harvest, achieving insect control without the need for pesticides, making pest control more environmentally friendly and healthy.

[0004] The existing technology has the following problems:

[0005] 1. Most of the existing green pest control nets for cowpea cultivation are set up as one-piece structures. This means that when laying the greenhouse, multiple pieces of the insect control net need to be spliced ​​together. However, the existing technology generally uses sewing to splice the insect control nets, which is inconvenient to assemble and disassemble, which is very troublesome, reduces work efficiency, and increases the workload.

[0006] 2. Existing green pest control nets for cowpea cultivation do not have insect-repelling functions. This results in a large number of insects adhering to the surface of the nets during use, which is not only difficult to clean, but also causes corrosion or damage to the nets, reducing their service life and failing to meet usage requirements. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a split-type insect-proof net for green pest control in cowpea cultivation. This solves the problem that most existing insect-proof nets are designed as a single unit, which requires multiple pieces of netting to be joined together when laying them in greenhouses. However, existing insect-proof nets are generally joined by sewing, which is inconvenient to assemble and disassemble, and lacks insect-repelling function. This results in a large number of insects adhering to the surface of the net during use, which is not only difficult to clean, but also causes corrosion or damage to the netting.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a split-type insect-proof net for green pest control in cowpea cultivation, comprising a net body, an insect-repelling component on one side of the front of the net body, a first edge-pressing strip on the top of the net body, a second edge-pressing strip on one side of the net body, a first connecting hole on the top of the second edge-pressing strip, a positioning block on one side of the second edge-pressing strip, a third edge-pressing strip on the other side of the net body, a positioning hole on one side of the third edge-pressing strip, a second connecting hole on the top of the third edge-pressing strip, a connector inside the second connecting hole, and a fastening nut on one side of the bottom of the connector.

[0009] As a preferred technical solution of this utility model, the insect repellent component includes a metal ring, an elastic pad is provided on the inner wall of the metal ring, a medicine bottle is provided inside the elastic pad, an evaporation hole is provided on the outer surface of the medicine bottle, a sealing plug is provided at the mouth of the medicine bottle, and a protective cap is provided on the front of the sealing plug.

[0010] As a preferred embodiment of this utility model, the elastic pad is installed on the metal ring by adhesive connection, the size of the metal ring is adapted to the size of the medicine bottle, and the medicine bottle contains a volatile insect repellent drug.

[0011] As a preferred embodiment of this utility model, the sealing plug and the protective cap are integrated, the position of the protective cap corresponds to the position of the evaporation hole, and there are several groups of evaporation holes arranged in a ring array.

[0012] As a preferred embodiment of this utility model, the positions of the first connecting hole and the second connecting hole are respectively arranged to correspond to each other, the size of the first connecting hole and the size of the second connecting hole are adapted to the size of the connector, and the connector is U-shaped in general.

[0013] In a preferred embodiment of this utility model, the positioning block and the second pressing strip are integrally formed, and the position of the positioning block corresponds to the position of the positioning hole.

[0014] As a preferred technical solution of this utility model, the fastening nut is installed on the connector by a threaded connection, and the second and third pressure strips are both provided with mounting grooves that are adapted to the size of the fastening nut.

[0015] Compared with the prior art, this utility model provides a split-type insect-proof net for green pest control in cowpea cultivation, which has the following beneficial effects:

[0016] 1. This split-type insect-proof net for green pest control in cowpea cultivation is designed with a second edge strip, a first connecting hole, a positioning block, a third edge strip, a positioning hole, a second connecting hole, a connector, and a fastening nut. During assembly, the second edge strip on the insect-proof net is aligned with the third edge strip on the adjacent net, and the positioning block is inserted into the positioning hole to position the two sets of nets. Then, the connector is fitted into the first and second connecting holes, and the fastening nut is used to lock the bottom of the connector, completing the assembly. During disassembly, the fastening nut is first rotated in the opposite direction to separate it from the connector, and then the connector is removed, allowing direct separation of the two sets of nets. This design provides a split-type structure for the insect-proof net, avoiding the inconvenience of assembling and disassembling nets, improving work efficiency, and reducing labor.

[0017] 2. This split-type insect-proof net for green pest control in cowpea cultivation consists of a metal ring, elastic pad, medicine bottle, evaporation vent, and protective cap. In use, the medicine bottle is first placed inside the metal ring. The elastic pad ensures a tighter fit between the bottle and the inner wall of the metal ring, improving the bottle's stability and firmness. The volatile medicine inside the bottle then diffuses through the evaporation vent to the surrounding area of ​​the net, giving it both insect-repelling and insect-preventing properties. Finally, the protective cap protects the evaporation vent from rain. This design enables the insect-proof net to repel insects, preventing the net from accumulating large numbers of insects on its surface during use, thus extending its lifespan and meeting usage requirements.
