Description

Technical Field

[0001] The present invention relates to the field of pest control, and in particular to a pest trapping device for plant pest control. Background Art

[0002] The design of pest traps is based on the three major insect tropisms: phototaxis, colorattraction and chemotaxis. Currently, the recyclable technology of chemotaxis is more mature.

[0003] The pest trapping devices currently on the market, especially those that integrate multiple functions or apply cutting-edge technologies, often have a rather cumbersome operating process, requiring users to follow a series of complex steps. Moreover, after the device has collected a sufficient number of pests, the user is often forced to directly replace the internal components of the device due to the extremely complicated cleaning process of the internal components. This practice directly leads to a significant increase in the cost of using the equipment. In addition, to prevent the trapping liquid inside the device from leaking, the internal structure of the trapping device is usually designed to be very tight, and the connections between the various components are tightly fitted. This requires users to use special tools and strictly follow a specific sequence when disassembling the device. Once the operation is improper, it is very easy to cause damage to the components, or even make it impossible to disassemble. In summary, the existing pest trapping equipment not only has a complex maintenance process, but also has a high cost of replacing components.

At this time, the trapping shell 211 is rotated clockwise to allow the sealing plate 124 to slide into the slide groove 214 in the card slot 213, and then the trapping cylinder is pulled out horizontally upwards, the trapping cylinder is grasped, and the installation sleeve is disassembled. 217 is connected to the threaded connection of the filter cartridge 241, and then the push plate 245 is pushed to slide in the filter cartridge 241, thereby pushing out the mosquito corpses remaining in the filter cartridge 241.

In this way, the trapping liquid flows inside the trapping shell 211 and flows downward under the action of gravity. At the same time, mosquitoes sense the trapping liquid and come into contact with it, and fall into the filter cylinder 241 along with the flow of the trapping liquid. The trapping liquid retained inside the sealed shell 111 can kill the mosquitoes, and the filter hole 243 can retain the mosquito corpses while ensuring that the trapping liquid flows out of the filter cylinder 241.

Since the height of the connecting pipe 335 and the telescopic cylinder 332 is higher than the conduit 123, when the external pump injects the trapping liquid into the tee 222, the trapping liquid will directly enter the liquid injection cylinder 121 and the conduit 123 under the action of gravity, and be discharged into the sealed shell 111 along the conduit 123 and the through hole 114, so that the trapping liquid slides down along the inner wall of the trapping shell 211, so that the mosquitoes that come into contact with the inside of the trapping shell 211 will directly fall into the filter cylinder 241 along the arc inside the trapping shell 211, thereby collecting the mosquito corpses and ensuring that the device can continue to trap mosquitoes.

Due to the provision of the clustering cylinder 216, when mosquitoes are lubricated by the trapping liquid and fall into the filter cartridge 241, it is difficult for the mosquitoes to escape in the first time due to the small diameter of the clustering cylinder 216, thereby ensuring the collection effect of the trapped mosquitoes by the device and reducing the possibility of mosquitoes escaping.

[0024] The frame assembly 31 includes a support platform 311 and a positioning column 312. The positioning column 312 is fixedly connected to the bottom of the support platform 311.

When the cluster shell or other parts of the device are blocked, resulting in the accumulation of mosquito corpses, the trapping liquid is difficult to fall into the sealed shell 111 again, and the trapping liquid will accumulate in the trapping shell 211. At this time, the accumulated trapping liquid triggers the pressure sensor 215, and the pressure sensor 215 will close the control valve 223, so that the trapping liquid input by the external pump will quickly enter the telescopic cylinder 332 along the support blocks 321 and the connecting pipes 335. The telescopic cylinder 332 will continue to descend under the action of the internal pressure, thereby squeezing the mosquito corpses accumulated in the trapping shell 211 downward into the filter cylinder 241. In this way, the device has an anti-blocking effect when in use, improves the emergency treatment function, and reduces the resource investment in manpower maintenance of the device.

[0025] The working principle of the pest trapping device for plant disease and insect control provided by the present invention is as follows: When in use, the hose 23 connected to the tee 222 is connected to the discharge port of the external pump, and the hose 23 connected to the recovery drum 13 is connected to the liquid inlet of the pump. When the pump is running, it will continuously extract the trapping liquid at the bottom of the sealed shell 111 and inject the trapping liquid into the tee 222 along the hose 23; When the device is in the trapping state, the pump is running, and a large amount of trapping liquid enters the liquid injection cylinder 121 along the hose 23. At this time, a large amount of trapping liquid will be injected into the liquid injection hole 212 outside the trapping shell 211 along the conduit 123, so that the trapping liquid flows inside the trapping shell 211 and flows downward under the action of gravity. At the same time, when mosquitoes sense the trapping liquid and come into contact with it, they will fall into the filter cylinder 241 along with the flow of the trapping liquid. The trapping liquid retained in the sealed shell 111 can kill the mosquitoes, and the mosquito corpses are retained through the filter hole 243, ensuring that the trapping liquid flows out of the filter cylinder 241. To recover the dead mosquitoes in the filter cartridge 241 to ensure the continued use of the device, the rotary drum 322 needs to be rotated so that the push block 334 above the rotary drum 322 and the telescopic cylinder 332 are deflected 180 degrees. At this time, the trapping shell 211 is rotated clockwise so that the sealing plate 124 slides into the slide groove 214 in the slot 213. The trapping shell is then pulled out horizontally and upwards. The trapping shell is grasped and the threaded connection between the mounting sleeve 217 and the filter cartridge 241 is disconnected. The push plate 245 is then pushed to slide inside the filter cartridge 241 to push out the remaining dead mosquitoes in the filter cartridge 241. After that, the filter cartridge 241 and the trapping shell 211 can be reinstalled. When the cluster shell or other parts of the device are clogged, resulting in the accumulation of mosquito corpses and the trapping liquid having difficulty falling into the sealed shell 111 again, the trapping liquid will accumulate in the trapping shell 211. At this time, the accumulated trapping liquid triggers the pressure sensor 215, and the pressure sensor 215 will close the control valve 223, so that the trapping liquid input by the external pump will quickly enter the telescopic cylinder 332 along the support block 321 and the connecting pipe 335. The telescopic cylinder 332 will continue to descend under the action of the internal pressure, thereby squeezing the mosquito corpses accumulated in the trapping shell 211 downward into the filter cylinder 241.

[0026] Compared with related technologies, the pest trapping device for plant disease and insect control provided by the present invention has the following beneficial effects: When blockage occurs in the cluster shell or other parts of the device, resulting in the accumulation of mosquito corpses and the trapping liquid having difficulty falling into the sealed shell 111 again, the trapping liquid will accumulate in the trapping shell 211. At this time, the accumulated trapping liquid triggers the pressure sensor 215, and the pressure sensor 215 will close the control valve 223, so that the trapping liquid input by the external pump will quickly enter the telescopic cylinder 332 along the support block 321 and the connecting pipe 335. The telescopic cylinder 332 will continue to descend under the action of internal pressure, thereby squeezing the mosquito corpses accumulated in the trapping shell 211 downward into the filter cylinder 241. In this way, the device has an anti-blocking effect when in use, improves the emergency treatment function, and reduces the resource investment in manpower maintenance of the device.

[0027] When the device is in the trapping state, the pump starts to run, and a large amount of trapping liquid enters the liquid injection cylinder 121 along the hose 23, and then is injected into the liquid injection hole 212 outside the trapping shell 211 along the conduit 123. In this way, the trapping liquid flows inside the trapping shell 211 and flows downward under the action of gravity. At the same time, mosquitoes sense the trapping liquid and come into contact with it, and fall into the filter cylinder 241 along with the flow of the trapping liquid. The trapping liquid retained inside the sealed shell 111 can kill the mosquitoes, and the filter hole 243 can retain the mosquito corpses while ensuring that the trapping liquid flows out of the filter cylinder 241. In this way, during the operation of the pump, the device can continuously extract the trapping liquid, ensure its flow effect, and prevent the trapped mosquitoes from breaking free, thereby improving the trapping effect of the device.

[0028] Since the height of the connecting tube 335 and the telescopic cylinder 332 is higher than the conduit 123, when the external pump injects the trapping liquid into the tee 222, the trapping liquid will directly enter the liquid injection cylinder 121 and the conduit 123 under the action of gravity, and be discharged into the sealed shell 111 along the conduit 123 and the through hole 114, so that the trapping liquid slides downward along the inner wall of the trapping shell 211. This ensures that the mosquitoes that come into contact with the inside of the trapping shell 211 will directly fall into the filter cylinder 241 along the arc inside the trapping shell 211, thereby collecting the mosquito corpses and ensuring that the device can continue to trap mosquitoes.
