Description

Technical Field

[0001] The utility model belongs to the technical field of pest trapping, in particular to a farmland pest trap. Background Art

[0002] A farmland pest trap is a device used to control farmland pests. It usually uses the pests' phototaxis, chemotaxis and other characteristics to attract pests through specific attractants or light sources. The trap is generally composed of a trapping device, a container and fixed parts. Common ones include light traps, which use light of a specific wavelength to attract pests and then physically capture them in a container; there are also sex pheromone traps, which release odors similar to pest sex pheromones to attract male pests into the trap. Farmland pest traps have the advantages of being green, environmentally friendly and highly targeted. They can reduce the use of chemical pesticides and reduce pollution to the environment. At the same time, they can effectively control the number of pests and protect the growth of crops. For example, the reasonable arrangement of pest traps in large areas of farmland can significantly reduce the degree of damage caused by pests and increase the yield and quality of crops.

[0003] The Chinese patent publication number "CN218164068U" discloses a pest trap for farmland prevention and control, which includes an insect receiving bucket, which is in the shape of an inverted truncated cone, and the bottom end of the insect receiving bucket is connected to a vertical circular conduit, the outer ring of the bottom of the conduit is provided with a thread, and the outer ring thread sleeve of the bottom of the conduit is provided with a circular collecting box without a top wall, vertical columns are fixed on the inner side walls of both sides of the insect receiving bucket, the outer ring fixed sleeve of the column is provided with a support block, the outer ring movable sleeve of the column located on the upper side of the support block is provided with a vertical vertical sleeve, the top end of the support block and the bottom end of the vertical sleeve are connected with a vertical vibrating spring, and the outer ring fixed sleeves of the two vertical sleeves are provided with a horizontal flat plate. The utility model is ingenious in conception and can automatically clean pests attached to the insecticidal lamp without manually cleaning the pests attached to the insecticidal lamp. The pest cleaning process consumes less manpower and has a high efficiency in cleaning pests, and it is convenient to remove pests inside the pest collection container;

[0004] During the use of the above device, it uses a vibration motor to assist in shaking the entire device to clean the insect corpses. However, it still has certain defects and shortcomings during its specific use. First, the insect corpses are relatively stubbornly adhered to the external electric insect net cover. Therefore, it is obviously difficult to clean them stably by just shaking. It is obviously impossible to clean the firmly adhered impurities. In addition, the violent shaking state during the cleaning process will cause the insect-attracting lamp and the electric insect net to be in a violent shaking state, which will obviously affect the normal use of electronic components and even cause them to be damaged. In addition, its vibration motor still needs to be manually controlled. On the one hand, it needs to be manually started, and on the other hand, it needs to share electricity. The overall electricity consumption is large. It can be seen that it has certain defects and shortcomings, so it needs to be improved.

[0005] During the actual application of the above-mentioned device, although a vibration motor is used to assist in shaking the entire device to clean the insect corpses, there are still many defects and shortcomings in the specific use process. First, the insect corpses are often stubbornly adhered to the external electric insect net cover. It is obviously difficult to clean them stably and thoroughly by relying solely on shaking. It is even more powerless for impurities that are extremely firmly adhered. Moreover, during the cleaning process, the violent shaking state will cause the insect-attracting lamp and the electric insect net to be in a state of continuous violent shaking, which will undoubtedly have a serious impact on the normal use of electronic components and may even cause them to be damaged. In addition, the operation of the vibration motor still requires manual electronic control. On the one hand, it requires manual start-up, which increases labor costs and operational complexity; on the other hand, the operation of the vibration motor also consumes a lot of electricity, and the overall electricity consumption is large, which is not conducive to energy saving and environmental protection. In summary, the device has obvious defects and shortcomings at the existing technical level and urgently needs to be improved. Utility Model Content

It can be easily adjusted without the aid of tools, improving the installation and use efficiency of the device and bringing great convenience to the farmland pest trapping work.

[0030] Principle and advantages of use: During the actual application of this device, by carefully setting the inclined rain shelter 3, its shielding effect on the electric insect net cover 5 can be fully exerted during use. In this way, rainwater can be effectively prevented from directly hitting the electric insect net cover 5, thus playing an excellent protective performance. During its use, the ingenious setting of the insect attracting lamp 8 and the photosensitive switch 10 is unique. During the day, the photosensitive switch 10 can accurately detect the brightness and adaptively turn off the insect attracting lamp 8 and the electric insect net cover 5 to save energy; while at night, the photosensitive switch 10 detects the brightness again and starts the insect attracting lamp 8 to operate in a timely manner. The light emitted by the insect attracting lamp 8 is extremely attractive and can lure pests to approach. Once the pests touch the electric insect net cover 5, they will be instantly electrocuted, and the killed insect corpses will naturally fall into the collection hopper 13 on the bottom plate 12. When it is necessary to clean the insect corpses, just easily turn the hand-tightening bolt to achieve disassembly, and the operation is extremely convenient. In addition, the design of using the telescopic rod 2 during the use of this device is very considerate. When installing and using, according to specific use requirements, the sliding of the sliding rod 22 inside the rectangular tube 21 can be flexibly adjusted. By sliding up the sliding rod 22, the rain shelter 3, the insect attracting lamp 8 and the insect killing electric net can be lifted, so as to achieve the purpose of flexibly adjusting its use height. After the height adjustment is completed, just turn the adjusting bolt and insert it into the limiting hole 23 to firmly fix the telescopic rod 2. It can be seen that during the use of this device, on the one hand, the height can be flexibly adjusted according to the actual situation, and on the other hand, the photovoltaic panel 11 can be fully utilized to supply power to the battery inside the chassis 9, which not only reduces energy consumption, but also does not require external line connection, and the installation is more convenient and efficient;

[0031] By setting up a kinetic energy mechanism, the present device shows many advantages in daily use. The wind force formed by outdoor air circulation can be used to blow the arc-shaped blades of the vertical wind wheel. When the arc-shaped blades 633 of the vertical wind wheel are pushed by the wind, the rotating shaft 62 can be driven to rotate. The rotation of the rotating shaft 62 can directly drive the top frame 71 at the bottom to rotate. The rotation of the top frame 71 can drive the cleaning plate 72 to rotate around the electric insect mesh cover 5. The rotation of the cleaning plate 72 can drive the cleaning soft brush 73 to carefully brush and clean the electric insect mesh cover 5. At this time, the insect corpses or impurities and dust on the electric insect mesh cover 5 can be effectively cleaned. Using wind as power to drive the cleaning soft brush 73 to brush and clean has many significant advantages. On the one hand, its brushing and cleaning is continuous. And the contact is stable, which can achieve efficient and thorough cleaning function; on the other hand, it will automatically clean as long as there is wind during the cleaning process, and there is no need to rely on electricity and manpower to drive it during the overall application. It truly has an automatic cleaning function in a substantial sense, and during the rotation of the rotating shaft 62, it can drive the large gear 635 to rotate, and the rotation of the large gear 635 can drive the small gear 634 to rotate, and then drive the micro generator 636 to generate electricity. The large gear 635 drives the small gear 634 to rotate, which can drive the micro generator 636 to generate electricity more lightly and efficiently. It cooperates with the photovoltaic panel 11 to achieve a completely self-sufficient power supply. The overall application is more energy-saving and efficient, providing reliable technical support for the trapping of farmland pests.
