[0043] Embodiment 2

[0044] Embodiment 2 is a further description of Embodiment 1. The same components are not described here again. Figure 1-6 The base 15 is cylindrical, and the diameter of the base 15 is slightly smaller than the inner diameter of the housing 11, and a 0.5mm assembly gap is reserved during the design; the actuator 14 is a telescopic motor or an electric push rod, and preferably, a telescopic motor is used as the actuator 14; a mounting groove 154 for placing the actuator 14 is provided on the base 15; a moving groove 155 for placing the output end of the actuator 14 is provided above the mounting groove 154; the mounting hole 151 is provided above the moving groove 155; the connecting rod 132 passes through the mounting hole 151 and is connected to the output end of the actuator 14, and the connection method can be plug-in.

[0047] Embodiment 3

[0048] Embodiment 3 is a further improvement of Embodiment 2, and the same components are not described here again. Figure 1-6 The insect collecting tube 13 is also cylindrical, and its diameter is slightly equal to the inner diameter of the shell 11, and an assembly gap of 0.5 mm is left; the left and right sides of the insect collecting tube 13 are provided with slide grooves 135 for limiting; the base 15 is provided with a support frame 156 used in conjunction with the slide groove 135, and there are two support frames 156, which are respectively arranged corresponding to the slide grooves 135 on the left and right sides of the insect collecting tube 13; after installation, the support frame 156 is engaged with the corresponding slide groove 135 to further limit the movement direction of the insect collecting tube 13.

[0049] Because the insect collecting tube 13 is also cylindrical, its diameter is slightly equal to the inner diameter of the shell 11; when the insect collecting tube 13 is away from the base 15, a closed space is formed between the bottom of the insect collecting tube 13 and the base 15, ensuring that all the pests in the insect collecting tube 13 can be discharged without getting stuck inside.

When installing, the support frame 156 is relatively long, and plastic can be preferably selected when selecting materials, so it has a certain elasticity. Only by inserting the assembly protrusion 161 into the assembly hole 1571, the connection between the support frame 156 and the sealing cabin 16 can be achieved and fixed; when designing, it is necessary to reserve a certain space for the insect collecting tube 13, so the length of the support frame 156 should be longer than the length of the insect collecting tube 13; preferably, the length of the support frame 156 is longer than the length of the insect collecting tube 13 by just equal to the diameter of the first small hole 131.

[0052] The camera 121 is arranged at the bottom of the circuit board 12 and directly faces the insect collecting tube 13. Therefore, in order to ensure the normal shooting of the camera 121, the top of the insect collecting tube 13 is open. Because the insect collecting tube 13 is arranged vertically, the pests entering the insect collecting tube 13 will naturally fall to the bottom of the insect collecting tube 13 under the action of gravity. Therefore, there is no need to worry that the pests will be discharged from the top of the insect collecting tube 13. In addition, because the gap between the top of the insect collecting tube 13 and the sealed cabin 16 is not too large, it can also effectively prevent the pests from crawling out.

[0053] The bottom surface of the sealed cabin 16 is made of transparent material, preferably transparent plastic; setting the camera 121 in the sealed cabin 16 can prevent the corrosive gas in the grain from damaging the camera 121; and making the bottom surface of the sealed cabin 16 from transparent material can ensure that the shooting function of the camera 121 is normal.
