Description

Technical Field

[0001] The utility model relates to an insect catching device, in particular to a harmful insect trapping device for forestry management. Background Art

[0002] Pest control is one of the important projects in forestry management. Currently, the main means of pest control include spraying pesticides and deploying insecticide control equipment.

[0003] After searching, the patent with announcement number CN220674915U discloses a forestry pest trapping device, which is connected to the upper surface of a fixed cylinder through a horizontal plate, and the horizontal plate is used to install a motor. The motor drives the rotating rod at the bottom to rotate, and the rotating rod drives the fan at the bottom to operate. When pests appear above the first funnel, the airflow generated by the fan will blow the pests into the cylinder below, thereby achieving the effect of improving the trapping efficiency of the pests.

[0004] The above scheme uses the airflow generated by the fan when it is running to blow the pests toward the first funnel, so that the pests fall into the cylinder and the collection bucket. However, since a filter plate is provided between the fan and the first funnel, it will cause a large loss of wind force. In addition, since the inlet of the first funnel is large and the outlet is small, it will also block the wind. In addition, after the cylinder and the collection bucket are connected, they are only connected to the outside world through the first funnel. Therefore, it is difficult for the wind blown by the fan to enter the cylinder through the first funnel in large quantities, and the insect catching effect is not good, which needs to be improved.

[0020] The utility model adopts the above scheme. Since a plurality of through holes 10 are provided on the cone barrel 9, the cylinder 1, the collecting tube 8 and the annular mounting seat 11 are interconnected. When in use, after turning on the insect attracting lamp 5 and the fan 12 at night, the pests will be attracted by the insect attracting lamp 5 to between the lampshade 3 and the cylinder 1. Under the action of the fan 12, the air above the cylinder 1 will be drawn into the cylinder 1 and discharged from the bottom end of the annular mounting seat 11, so that the pests are brought into the cylinder 1 and fall into the collecting tank 8. Under the action of the airflow, it is difficult for the pests to fly out from the top opening of the cylinder 1, and under the obstruction of the cone barrel 9, they cannot escape from the bottom opening of the collecting tank 8, so that the pests can be trapped and the use effect is good.

[0021] Specific combination Figure 2 In one embodiment of the utility model, a funnel 7 is fixedly connected to the inner wall of the top opening of the cylinder 1. Through the setting of the funnel 7, the pests entering the cylinder 1 need to accurately fly into the bottom opening of the funnel 7 and overcome the resistance of the airflow before flying out of the cylinder 1, which effectively increases the difficulty of the pests to escape.

[0022] Specific combination Figure 2 and Figure 3 In one embodiment of the utility model, a slot 13 adapted to the outer diameter of the bottom end of the collection tank 8 is opened on the top of the annular mounting seat 11, and a sealing ring 14 is embedded in the slot 13, and the inner wall of the sealing ring 14 is in contact with the outer wall of the bottom end of the collection tank 8.

[0023] The provision of the slot 13 facilitates the installation of the annular mounting seat 11 at the bottom end of the collecting tank 8 , and the provision of the sealing ring 14 ensures the sealing between the annular mounting seat 11 and the collecting tank 8 .

[0024] Specific combination Figure 2 In one embodiment of the utility model, two connecting seats 15 are symmetrically fixedly connected to the outer wall of the annular mounting seat 11 on both sides, and the tops of the connecting seats 15 are fixedly connected to guide rods 16. The outer wall of the guide rod 16 is slidably sleeved with a guide sleeve 17. The top of the guide rod 16 is fixedly connected to a limiting block 18. The outer wall of the guide rod 16 located between the guide sleeve 17 and the limiting block 18 is sleeved with a spring 19, and the guide sleeves 17 are fixedly connected to the outer wall of the cylinder 1.

[0025] By providing a connecting seat 15, a guide rod 16, a guide sleeve 17, a spring 19 and a limit block 18, the annular mounting seat 11 can be suspended below the cylinder 1, and the spring 19 can always apply an upward pulling force to the annular mounting seat 11, thereby ensuring the stability of the connection between the annular mounting seat 11 and the collection tank 8, and preventing the annular mounting seat 11 from falling from the bottom end of the collection tank 8.

[0026] In addition, in one embodiment of the utility model, the inner wall of the top opening of the collecting tank 8 is threadedly connected to the outer wall of the bottom end of the cylinder 1, so as to facilitate disassembly and assembly of the collecting tank 8 at the bottom end of the cylinder 1.
