Description

Technical Field

[0001] The utility model belongs to the technical field of pest control and relates to a tobacco beetle trapping and dust-proof device. Background Technique

[0002] As an important cash crop, tobacco is closely related to people's daily life. During the production process of tobacco, it often happens that tobacco beetles bore into and eat tobacco leaves and cigarettes, and the reproductive ability of tobacco beetles is relatively strong, which brings great adverse effects to the normal production of tobacco. In all links of tobacco production, generally, tobacco beetle traps are used to trap tobacco beetles. The trap mainly attracts tobacco beetles with a trapping board, and the adhesive on the trapping board sticks to the beetles to achieve the killing effect.

[0003] In the actual application process of tobacco beetle traps, dust in the tobacco storage and processing process is easily attached to the adhesive board. Especially when used in places with a large amount of dust, blowing will raise a large amount of dust, seriously affecting the viscosity of the adhesive board, resulting in a weak or lost trapping effect of the trapping board, affecting the working efficiency of the trap, and requiring more time to replace the adhesive board, causing waste of resources and inconvenience in use. Therefore, the improvement of tobacco beetle traps usually involves adding dust-proof structures or components to avoid the problem of the trap failing due to dust being too easy to contact the trapping board and extend the service life of the trap.

[0004] CN 210299159U discloses a new type of tobacco beetle trap, including a bottom plate and a dust-proof cover. One side of the dust-proof cover is hinged to the bottom plate, and the other side is clamped. The front of the bottom plate is provided with a clamping edge to fix the trapping board. The dust-proof cover covers the trapping board. The bottom plate is provided with a plurality of through holes for tobacco beetles to enter. There is a rectangular plastic support plate on the back of the bottom plate, and a hanging ear is provided at the top of the support plate. The dust-proof cover is an integral structure and does not have a filter screen. The through holes are arranged on the bottom plate to reduce the entry of dust, but this will also be unfavorable for the entry of tobacco beetles. And in the case of cleaning or a large amount of dust, dust is still easy to enter the trap, affecting the realization of the trapping function and having a short service life.

[0005] CN 103918628 A discloses a dust-proof box for a tobacco beetle trap. The dust-proof box includes a top plate, a bottom plate, a front baffle, a rear baffle and side baffles. The rear baffle and two side baffles are fixed to the bottom plate. One side of the top plate is movably connected to the rear baffle through a rotating shaft, and the other side is fixedly connected to the front baffle. Through holes are uniformly arranged on the baffle surfaces above the midlines of the front baffle and the rear baffle. The dust-proof box further includes a first inner partition and a second inner partition. The bottom side of the first inner partition is fixedly connected to the bottom side of the front baffle through a connecting plate. The second inner partition is fixed to the bottom plate. A hook is fixedly installed at the top end position of the first inner partition. A fence structure is arranged at the position below the midlines of the first inner partition and the second inner partition. The structure of this dust-proof box has through holes on the front and rear baffles and cannot prevent the entry of dust. Although the staggered arrangement of the inner partition and the gap position of the baffle reduces the amount of dust reaching the trap to a certain extent, the effect is not significant when there is a large amount of dust during cleaning.

[0006] In summary, for the structure of the tobacco beetle trapping and dust-proof device, a movable dust-proof structure needs to be added for use when there is a large amount of dust during cleaning, so as to avoid the failure of the trapping function caused by the reduced viscosity of the trapping plate, and there is no need to frequently replace the trapping plate, reducing costs. Utility Model Content

[0007] Aiming at the problems existing in the prior art, the purpose of the present utility model is to provide a tobacco beetle trapping and dust-proof device. The trapping and dust-proof device avoids the influence of a large amount of dust entering the device during cleaning on the function of the trapping plate through the setting of a filter structure on the front baffle and the filter membrane in the filter structure, ensures the effectiveness of the trapping device, and at the same time does not require frequent replacement of the trapping plate, reducing costs. The filter is easy to replace, fast and efficient, and has a low cost.

[0008] To achieve this purpose, the present utility model adopts the following technical solutions:

[0009] The present utility model provides a tobacco beetle trapping and dust-proof device. The trapping and dust-proof device has an overall cuboid hollow structure.

An attractant core and a trapping plate are arranged inside the cuboid hollow structure. The trapping plate is located on the rear baffle of the cuboid hollow structure and is arranged parallel to the rear baffle. The attractant core is arranged on the trapping plate.

[0010] The filter structure includes at least two layers of filter membranes. The filter membranes include inorganic filter membranes and organic filter membranes. The filter structure is a telescopic door stop structure.

[0011] In the present utility model, for the trapping device of tobacco beetles, by adding a dust-proof structure, it helps to extend its service life. On the basis of the structure of the traditional trap, a filter structure is provided on the front baffle, specifically a retractable door stop structure, so that the filter can be extended or retracted. When normally trapping tobacco beetles, the filter is not needed. At this time, the filter retracts to leave a space, and the tobacco beetles enter from here and adhere to the trapping board. When cleaning, the amount of dust is usually large. Pull down the filter structure, and specifically through the setting of inorganic and organic filter membranes, the dust particles are blocked outside the filter structure, avoiding the influence of dust on the trapping board and the trapping core, so that its trapping effect can be guaranteed and it can still be used normally after cleaning; after the filter structure is set, there is no need to frequently replace the trapping board, and only the filter needs to be replaced.
