[0041] In the embodiment, the trapping assembly 3 comprises a capturing piece in which an attractant can be stored to trap tobacco bruchids, a collecting piece which can display the trapping amount of the device and is easy to replace, and a limiting piece which can change the position of the collecting piece according to its weight;

[0042] The capturing piece comprises the introduction funnel 304 arranged on the bracket 201, the bending pipe 305 fixedly connected to the lower side of the introduction funnel 304, the limiting piece comprises the guide plate 306 fixedly connected to the lower end of the bending pipe 305, the collecting piece comprises the carrier plate 309 movably installed below the guide plate 306, two outlet pipes 310 are fixedly connected to the carrier plate 309, the positioning grooves are integrally formed on the outer side of the lower end of the outlet pipes 310, the collecting bags 311 are arranged at the lower end of the outlet pipes 310, the elastic bands 312 are sleeved on the outer side of the collecting bags 311 located in the positioning grooves, and the capturing piece further comprises the cover 301 fixedly connected to the lower end of the hanging rope 206, the plug 302 is arranged on the cover 301, the storage hopper 303 is fixedly connected to the lower side of the cover 301, the introduction funnel 304 fixedly connected to the cover 301 is arranged below the storage hopper 303, the limiting piece further comprises the two guide rods 307 fixedly connected to the guide plate 306, the springs 308 are movably connected to the outer side of the guide rods 307, and the carrier plate 309 is arranged on one side of the springs 308;

[0043] The guide plate 306 and the guide rod 307 are in sliding connection with the carrier plate 309, the guide rod 307 is in sliding connection with the spring 308, the storage hopper 303 is provided with a plurality of air holes, the guide-in hopper 304 is provided with a plurality of trapping grooves, and the guide-out pipe 310 has an oval cross section;

[0044] The cover 301 hung by the hanging rope 206 provides a mounting position for the plug 302, the storage hopper 303 and the guide-in hopper 304, the storage hopper 303 divides the internal space surrounded by the cover 301 and the guide-in hopper 304, and cooperates with the cover 301 to form an area for placing an attractant, the plug 302 can be removed to conveniently fill the storage hopper 303 with the attractant, the storage hopper 303 with the air holes allows the attractant placed therein to volatilize and diffuse naturally, the guide-in hopper 304 with the trapping grooves allows the tobacco granary weevil to enter the space between the storage hopper 303 and the guide-in hopper 304, the curved pipe 305 provides a mounting position for the guide plate 306, so that the guide plate 306 can be obliquely arranged and guide the tobacco granary weevil falling thereinto to the carrier plate 309 abutting the guide plate 306, the guide rod 307 and the spring 308 limit the change of the position of the carrier plate 309 below the guide plate 306, and allow the collection assembly composed of the carrier plate 309 and other components to move downward along the guide plate 306 when the weight increases, the contraction force of the elastic band 312 forms a restraining action, so that the collection bag 311 capable of containing a certain amount of tobacco granary weevil can stably close the open end of the guide-out pipe 310, and is easy to disassemble and assemble, and the guide-out pipe 310 fully guides the tobacco granary weevil falling to the carrier plate 309 into the collection bag 311 connected thereto.

[0045] Working principle: when the device is installed for trapping tobacco granary weevil in the field, the device is moved to a suitable position in the field, the ground anchor 104 is inserted into the soil, and then the two positioning pins 203 are rotated to adjust the height of the bracket 201 and the carriage 202, so as to adjust the suspension height of the trapping assembly 3 and make the bracket 201 stably hold the guide-in hopper 304. After the adjustment is completed, the plug 302 is removed, an appropriate amount of attractant is placed into the storage hopper 303, and then the plug 302 is reassembled, so that the device can trap the tobacco granary weevil;

[0046] Specifically, the tobacco powder mite outside the device is attracted by the luring agent in the storage hopper 303 and enters the luring groove of the introduction hopper 304 between the storage hopper 303 and the introduction hopper 304. Since the outer side of the storage hopper 303 and the inner side of the introduction hopper 304 are inclined and the distance between them gradually decreases from high to low, the tobacco powder mite entering the device will gradually stay in the area below the storage hopper 303 with extremely high concentration of luring agent and is difficult to leave from the introduction hopper 304. In order to ensure the killing effect, a contact insecticide can be coated on the outer side of the storage hopper 303 and the inner side of the introduction hopper 304, and a toxic luring agent can be selected. With the increase of the staying time of the tobacco powder mite in the introduction hopper 304, the tobacco powder mite will be killed and gradually falls into the collection bag 311 along the elbow pipe 305 and the discharge pipe 310 under the action of gravity;

[0047] When the collection bag 311 becomes heavy due to the increase of the number of tobacco powder mites inside, the carrier plate 309 will drive the discharge pipe 310 and other components to move downward along the guide plate 306. Since the discharge pipe 310 has an oval cross section, most of the trapped tobacco powder mites will fall into the collection bag 311 at a lower position during the downward movement of the carrier plate 309. When the carrier plate 309 moves to a certain height, the subsequent trapped tobacco powder mites will fall into the collection bag 311 connected to the discharge pipe 310 at a higher position. Therefore, the worker can roughly judge the amount of trapping by observing the appearance of the two collection bags 311 or the position of the collection bag 311 in the device. When it is necessary to clean the trapped tobacco powder mites, the worker only needs to loosen the elastic band 312 interface, remove the collection bag 311 and replace it, and then destroy the removed collection bag 311 to quickly complete the cleaning work.

[0048] The preferred embodiments of the present application are described in detail above in combination with the drawings, but the present application is not limited to the above-mentioned embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present application.
