Description

Technical Field

[0001] This utility model belongs to the field of plant protection technology, and in particular relates to an insecticidal device for plant protection. Background Technology

[0002] Pests directly feed on the leaves, stems, and fruits of crops, causing poor growth and stunted development. In severe cases, this can even lead to large-scale yield reduction. Pest control can effectively manage the number of pests, preventing them from harming crops and ensuring their normal growth and development, thus achieving stable and high yields.

[0003] For example, Chinese patent CN221829620U discloses an insect-killing device for plant protection, including an insect-collecting chamber. A slot is located on the lower right side of the chamber, and a collection trough is inserted into the slot. A push-pull groove is located in the middle of the right side of the collection trough. A collection bucket is fixed to the top center of the chamber, and a cleaning device is located below the collection bucket. Supports are fixed at the top corners of the chamber, and a top plate is fixed to the top of all four supports. Limiting blocks are symmetrically located on the left and right sides of the top center of the top plate, and a fixing device is located between two of the limiting blocks. Insect-killing lamps attract pests to the insect-killing net, where they are electrocuted and fall onto the inner wall of the collection bucket. They then enter the chamber through the collection bucket and finally fall into the collection trough. After a certain amount of pests are collected, the collection trough is pulled out of the chamber through the push-pull groove. After cleaning the pests from the collection trough, the collection trough is reinserted into the chamber through the slot.

[0004] The aforementioned patent has the following problems:

[0005] This patented device has several drawbacks in use. For example, the cleaning brush is fixed to the rotating plate, and pests easily adhere to the brush when cleaning, reducing its cleaning effectiveness. Additionally, the insect-killing net is fixed at the bottom center of the top plate, making it difficult to disassemble. If the net is damaged, maintenance personnel will find it difficult to inspect and replace it. Therefore, we propose an insect-killing device for plant protection. Utility Model Content

[0006] The purpose of this invention is to provide an insect control device for plant protection, in order to solve the problems mentioned in the background art.

[0007] In view of this, the present invention provides an insecticidal device for plant protection, comprising an insecticidal net and an insecticidal lamp, and further comprising:

[0008] The outer shell has first through holes on both the front and rear sides, second through holes on both the left and right sides, and a first inverted convex circular hole on the top. An annular plate is placed inside the first inverted convex circular hole, and an insect-killing net is fixedly installed at the bottom of the annular plate. A disc is placed inside the first inverted convex circular hole and at the top of the annular plate. A second inverted convex circular hole is opened in the disc, and an mounting plate is placed inside the second inverted convex circular hole. An insect-killing lamp is fixedly installed at the bottom of the mounting plate. A baffle is placed inside the first inverted convex circular hole and at the top of the disc.

[0009] A fixing component, located on the housing, is used to fix the baffle.

[0010] A through groove is provided on the rear side of the outer shell. A collection box is slidably installed at the bottom of the inner cavity of the outer shell. A drain pipe is fixedly installed at the discharge port of the collection box and inside the through groove. A water inlet pipe is fixedly installed on the right side of the outer shell.

[0011] A filter assembly located within a collection box and used for filtration.

[0012] In this technical solution, during use, the operator can rotate and open the sealing cap on the water inlet pipe due to the screw thread. Then, an appropriate amount of water and disinfectant can be injected into the collection box through the water inlet pipe. After that, the sealing cap is reinstalled on the water inlet pipe to prevent the water and disinfectant from spilling out. Then, the insecticidal lamp and the insecticidal net can be powered on and started. The insecticidal lamp will emit light to attract pests. The pests can enter the outer shell through the two first through holes and the two second through holes. When the pests come into contact with the insecticidal net, the insecticidal net will electrocute and kill the pests. The pests will then fall directly onto the liquid in the collection box.

[0013] When it's time to clean the pests from the collection box, the worker can turn and open the valve on the drain pipe. The liquid in the collection box will then pass through the filter assembly and flow from the discharge port into the drain pipe, exiting to the outside. The filter assembly blocks the pests, preventing them from escaping. After the liquid has drained, the collection box can be released from its locking pin and then pulled out of the casing to clean the pests. When cleaning or replacing the insecticidal net and lamp, the fixing assembly can be used to release the baffle. The baffle can then be pulled upwards, followed by pulling up the disc, which has a circular opening for easy lifting. The valve filter plate can then be removed from the second inverted convex hole. At this point, the annular plate will also be released, allowing the annular plate, along with the insecticidal net, to be removed upwards from the first inverted convex hole.

[0014] In the above technical solution, the fixing component further includes:

[0015] A rotating plate is rotatably mounted on the top of the outer shell and located on one side of the first inverted convex circular hole. A sliding groove is provided inside the rotating plate, and a limiting block is slidably installed in the sliding groove. One end of the limiting block passes through the bottom of the sliding groove and extends into the baffle. A pull rod is fixedly installed on the top of the limiting block. One end of the pull rod passes through the top of the sliding groove and extends to the outside. A spring is sleeved on the pull rod and located inside the sliding groove.

[0016] In this technical solution, when the insect-killing net and insect-killing lamp need to be cleaned or replaced, the worker can pull the lever upwards. The lever will cause the limiting block to move upwards, and the spring will contract under compression until one end of the limiting block is completely pulled out of the baffle. Then, the rotating plate can be rotated so that the rotating plate is no longer at the top of the baffle. At this time, the baffle will be released from its fixed position. The baffle can be pulled upwards, and then the disc can be pulled upwards. The disc has a circular opening, which makes it easy to lift it upwards. Then, the valve filter plate can be taken out from the second inverted convex circular hole. At this time, the annular plate will also be released from its fixed position. The annular plate, along with the insect-killing net, can be taken out upwards from the first inverted convex circular hole.

[0017] In the above technical solution, further, the two ends of the spring are tightly welded to the top of the limiting block and the inner wall of the slide groove, one end of the limiting block is inserted into the baffle, the pull rod is slidably connected to the rotating plate and the slide groove, and the bottom of the rotating plate is in contact with the top of the baffle.

[0018] In this technical solution, the structure of the spring is ensured to be stable, one end of the limiting block can be inserted into the baffle, the pull rod can slide in the rotating plate and the slide groove, and the rotating plate can limit the baffle.

[0019] In the above technical solution, the filtering component further includes:

[0020] Two L-shaped plates are fixedly installed inside the collection box and located on the left and right sides of the discharge port, respectively. A filter plate is inserted between the two L-shaped plates, and a rectangular plate is fixedly installed on the top of the filter plate.

[0021] In this technical solution, when it is necessary to clean the pests in the collection box, the staff can turn and open the valve on the drain pipe. Subsequently, the liquid in the collection box will pass through the filter plate and enter the drain pipe from the discharge port to be discharged to the outside. The filter plate can block the pests, so that the pests will not be discharged to the outside.

[0022] In the above technical solution, the filter plate is further fixed to two L-shaped plates by bolts, the bottom of the filter plate is in contact with the bottom of the inner cavity of the collection box, and one side of the filter plate is in contact with the inner wall of the collection box.

[0023] In this technical solution, the filter plate can be fixed between the two L-shaped plates by bolts, which also facilitates the disassembly and replacement of the filter plate and ensures that the filter plate can block pests.

[0024] In the above technical solution, a sealing cap is threadedly installed on the water inlet pipe, and a valve is rotatably installed on the drain pipe.

[0025] In this technical solution, the sealing cap can be removed from the water inlet pipe, and the operator can turn and open the valve on the drain pipe. Subsequently, the liquid in the collection box will pass through the filter plate and enter the drain pipe from the discharge port to be discharged to the outside.

[0026] In the above technical solution, the insect-killing net is located in the inner cavity of the outer shell, and the insect-killing lamp is located in the insect-killing net.

[0027] In this technical solution, it is ensured that the insect-killing net can electrocute pests that have entered the shell, and that the insect-killing lamp can attract pests to contact the insect-killing net.

[0028] In the above technical solution, the top of the mounting plate contacts the bottom of the baffle, and the collection box is fixed to the outer shell by a pin.

[0029] In this technical solution, the baffle is ensured to limit the mounting plate and the pin is ensured to fix the collection box to the outer shell.
