Description

Technical Field

[0001] This utility model relates to an agricultural field pest trapping device, which belongs to the field pest trapping equipment. Background Technology

[0002] Agricultural field pest trapping and monitoring devices are small-scale equipment whose goal is not to trap and kill pests on a large scale, but to monitor the types, quantities, and occurrence dynamics of pests in the field in real time. This provides data support for pest and disease early warning and scientific application of pesticides, achieving the monitoring goal of "early detection, early warning, and early prevention and control," thereby guiding agricultural production and reducing the overuse of pesticides.

[0003] For example, CN202410908905.2 discloses a pest trapping and monitoring device. The top of the casing is equipped with a solar panel; a lifting mechanism is located inside the casing, and the output end of the lifting mechanism has a movable vertical plate. Along the conveying direction of the yellow sticky trap roll, the movable vertical plate sequentially includes an unwinding mechanism, a first extension frame, a second extension frame, and a winding mechanism. The pest trapping and monitoring device provided by this utility model can automatically replace new yellow sticky traps and provide feedback on the pest trapping status of the yellow sticky traps. Furthermore, the height of the yellow sticky trap is adjustable, expanding the range of pests that can be trapped. However, this type of trapping device has a relatively complex structure and is difficult to deploy, failing to meet the requirements for rapid deployment. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an agricultural field pest trapping device. The goal is to create a trapping device that is simple in structure, easy to carry and deploy quickly, thus solving the problems of complex structure and high deployment cost of existing trapping devices.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: An agricultural field pest trapping device, suspended and installed on a lamppost, tree branch, or monitoring pole, is characterized by comprising an outer shell, an inner cylinder, a partition cylinder, a guide cylinder, an insect-collecting cone, an insect-collecting bottle, and a pheromone lure. The outer shell, partition cylinder, and inner cylinder are concentrically arranged from the outside in and all open downwards. The pheromone lure is disposed in the inner cavity of the inner cylinder. The guide cylinder passes through the outer shell and partition cylinder and its inner end is fixed to the inner cylinder. A window is provided on the wall of the guide cylinder to connect the inner cylinder and partition cylinder. The upper edge of the insect-collecting cone is fixedly connected to the outer shell, and there is a gap between the insect-collecting cone and the inner cylinder and partition cylinder. The insect-collecting bottle is mechanically installed at the lowest point of the insect-collecting cone.

[0006] Furthermore, a fan mounting opening is provided on the top of the outer casing to fix a miniature fan, which exhausts air from bottom to top after being powered on.

[0007] Furthermore, a rain cover is fixedly installed on the top of the outer shell. The rain cover is conical in shape, and a suspension point is welded to the apex of the rain cover.

[0008] Furthermore, the partition cylinder is composed of an annular portion and a top, and the top of the partition cylinder is mechanically fixed to the top cover of the outer casing in a suspended manner by four connecting columns.

[0009] Furthermore, a return air channel is formed between the inner wall of the partition cylinder and the inner wall of the outer shell, and the annular gap of the return air channel is between 1 cm and 2 cm.

[0010] Furthermore, the distance between the lower edge of the inner cylinder and the insect-collecting cone is four centimeters.

[0011] Furthermore, the upper surface of the insect-collecting cone and the lower edge of the septum body are kept at a distance of about four centimeters.

[0012] Furthermore, the number of guide cylinders is three, and they are evenly arranged along the circumference of the outer shell.

[0013] Furthermore, a counter for counting the number of pests is fixedly installed at the lowest bottleneck part of the insect collecting cone.

[0014] Furthermore, the insect-collecting cone and the insect-collecting bottle are connected by threads.

[0015] The beneficial effects of this utility model are: This device places the insect inlet tube laterally, allowing flying insects to fly horizontally into the device's interior, achieving 360-degree collection of pests and solving the problem of insufficient insect specimens caused by collecting insects from only one direction. The miniature fan in the device ensures that the airflow is aligned with the insects' flight direction and also prevents them from flying backwards.

[0016] This device is equipped with a counter to automatically count the pests that fall into the bottle and enables rapid disassembly of the bottle for quick sample preparation. Attached Figure Description

[0023] This embodiment will be described in conjunction with the appendix to the instruction manual. Figure 1 To be continued Figure 5 This paper introduces an agricultural pest trapping device for guiding agricultural production. The device has a cylindrical structure and is suspended from light poles, tree branches, or monitoring poles, offering flexible installation options while ensuring stability. It can be widely used in monitored areas such as fields.

[0024] This device includes an outer shell 10, an inner cylinder 20, a partition cylinder 30, a guide cylinder 40, an insect-collecting cone 50, an insect-collecting bottle 60, a miniature fan 11, a rain cover 12, a pheromone lure 70, a counter 80, and a power supply cable 13. The device is connected to an external power source via an external cable, such as a mobile power supply or a photovoltaic power generation system.

[0025] The outer casing 10 of this device is a stainless steel cylindrical structure with an open lower end. A fan mounting opening 14 is provided at the top of the casing 10, and a miniature fan 11 is fixedly mounted thereon. This miniature fan 11 exhausts air from bottom to top, drawing the gas inside the casing 10 outwards. A rain cover 12, which is conical in shape (like an umbrella), is welded to the outside of the casing 10 using three stainless steel plates. A suspension point is welded to the apex of the rain cover for suspension mounting. The rain cover 12 is positioned approximately five centimeters directly above the miniature fan 11, protecting its exhaust port.

[0026] The partition cylinder 30 is a cylindrical structure with its opening facing downwards. It consists of an annular part and a top. The top of the partition cylinder 30 is mechanically fixed to the top cover of the outer shell 10 by means of four connecting columns 31 in a suspended manner. The connection method at both ends of the connecting columns 31 is to fasten with screws. The four connecting columns 31 realize the suspension installation of the partition cylinder 30. After installation, an annular return air channel 32 is formed between the partition cylinder 30 and the inner wall of the outer shell 10. The return air channel 32 is an annular channel with a narrow width and a gap between the annulus and the rings between 1 and 2 centimeters.

[0027] Below the aforementioned partition cylinder 30 is installed an insect-collecting cone 50. The insect-collecting cone 50 is funnel-shaped, and its upper edge is fitted into the lower middle cavity of the outer shell 10 and secured with fastening screws. After securing, the upper surface of the insect-collecting cone 50 maintains a gap of about four centimeters with the lower edge of the partition cylinder 30, i.e., a distance of four centimeters.

[0028] The inner cylinder 20 is located inside the partition cylinder 30, and the inner cylinder 20, the partition cylinder 30 and the outer shell 10 are arranged concentrically. The inner cylinder 20 is an inverted cylindrical structure, that is, the opening of the inner cylinder 20 is set downwards, and the distance between the lower edge of the inner cylinder 20 and the insect collecting cone 50 is maintained at about four centimeters.

[0029] Three circular holes are provided on the outer shell 10 and three circular holes are provided on the corresponding partition cylinder 30 for installing guide cylinders 40. The guide cylinders 40 pass through the circular holes on the outer shell 10 and partition cylinder 30 from inside the outer casing, and their inner ends are fixedly connected to the outer wall of the inner cylinder 20, for example, by welding. Simultaneously, the outer port of the guide cylinder 40 is also fixed to the outer shell 10 by welding. The three guide cylinders 40 achieve mechanical fixation of the inner cylinder 20, forming a single unit.

[0030] Furthermore, the three guide cylinders 40 are evenly arranged along the circumference of the outer casing 10.

[0031] A window 41 is provided on the wall of the guide tube 40 located between the inner cylinder 20 and the partition cylinder 30. The window 41 is a small window for pests to pass through, and the window 41 connects the annular space between the inner cylinder 20 and the partition cylinder 30. That is, flying insects in the guide tube 40 fly into the space between the inner cylinder 20 and the partition cylinder 30 through the small window 41.

[0032] Furthermore, a sex pheromone 70 is suspended in the inner cylinder 20, containing a sex pheromone chemical substance to attract pests.

[0033] Furthermore, a bottleneck section is provided at the lowest point of the insect collecting cone 50, and a counter 80 is fixedly installed at the bottleneck section. The counter 80 counts the number of pests passing through the bottleneck section. The counter 80 is a separate counting module, which falls within the scope of existing technology and can be obtained by purchase.

[0034] An internal thread is provided at the lowest point of the bottleneck section, and an insect collection bottle 60 is quickly installed through the threaded connection to collect falling pests.
