Abstract
Description
Technical Field
[0001] This utility model relates to the field of pest control technology in grain storage, specifically to a pest trapping and collection device for grain storage warehouses. Background Technology
[0002] Pests in stored grain pose a significant challenge to food storage security. They can not only cause grain loss but also lead to a decline in grain quality and affect food safety.
[0003] Traditional pest trapping and collection devices work by connecting the trapping bottle and the collection bottle together, then using a light source to attract pests from inside the grain warehouse through a hole into the trapping bottle, and finally letting them fall into the collection bottle, thus trapping and collecting the pests in the grain warehouse. However, since the holes on the outer wall of the trap bottle are all the same size, pests smaller than the hole diameter (such as red flour beetle or rice weevil nymphs) can easily enter the trap bottle through the holes, while pests larger than the hole diameter (such as grain borer or large flour beetle) cannot enter the trap bottle smoothly, which directly leads to a limited trapping range and a significant decrease in the capture rate. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a pest trapping and collection device for grain storage warehouses. It solves the problem that because the holes on the outer wall of the trapping bottle are of uniform diameter, pests smaller than the hole diameter can enter the trapping bottle, while pests larger than the hole diameter cannot enter the trapping bottle smoothly, which directly leads to a limited trapping range and a significant decrease in the capture rate.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a pest trapping and collection device for grain storage silos, comprising a collection bottle, a trapping bottle fixedly attached to the upper inner wall of the collection bottle, and a bottom plate glued to the bottom of the collection bottle; the pest trapping and collection device for grain storage silos also includes a trapping component disposed inside the trapping bottle; and an auxiliary component disposed inside the collection bottle; wherein, the trapping component traps and collects pests in grain storage silos of all sizes, and the auxiliary component increases the range of pest trapping.
[0006] Preferably, the trapping assembly includes a first through hole located on the upper part of the outer wall of the trapping bottle; a second through hole located on the outer wall of the trapping bottle and below the first through hole; a third through hole located on the outer wall of the trapping bottle and below the second through hole; and three annular plates, each adhered to the inner wall of the trapping bottle. The first, second, and third through holes work together to allow pests of different sizes to enter the trapping bottle, while the annular plates block the three through holes.
[0007] Preferably, the auxiliary components include a box body, which is adhered to the bottom of the inner wall of the collection bottle; a cap is inserted into the top of the outer wall of the box body; a sponge is placed on the inner wall of the box body; and vertical holes are formed on the surface of the cap body; wherein, by dripping the attractant into the sponge, the attractant molecules are dispersed into the interior of the grain bin through the vertical holes.
[0008] Preferably, a battery box is bonded to the top of the outer wall of the trap bottle, and a lamp tube is fixed to the bottom of the battery box, with the lamp tube extending into the interior of the trap bottle through an opening.
[0009] Preferably, a drop nozzle is glued to the bottom opening of the trap bottle, and the drop nozzle is in the shape of an inverted cone.
[0010] Preferably, a limiting ring is adhered to the upper inner wall of the collection bottle, and the inner wall of the limiting ring is attached to the lower outer wall of the trapping bottle.
[0011] Beneficial effects
[0012] This invention provides a pest trapping and collection device for grain storage silos. It offers the following advantages: This pest trapping and collection device for grain storage silos, through the cooperation of a first through hole, a second through hole, a third through hole, and an annular plate, enables the trapping and collection of grain storage pests of different sizes. It solves the problem that because the holes on the outer wall of the trapping bottle have uniform diameters, pests smaller than the hole diameter can enter the trapping bottle, while pests larger than the hole diameter cannot enter smoothly, directly resulting in a limited trapping range and a significant decrease in the capture rate.
[0013] By combining the box, cover, sponge, and vertical holes, the diffusion of attractant molecules increases the range of pest trapping. This solves the problem of traditional devices that rely solely on light sources to attract grain warehouse pests, resulting in insufficient trapping coverage because the range of pest attraction by light sources is relatively small and some pests far from the light source cannot be attracted.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Because the holes on the outer wall of the trap bottle are all the same size, pests smaller than the hole diameter can enter the trap bottle, while pests larger than the hole diameter cannot enter the trap bottle smoothly, which directly limits the trapping range and significantly reduces the capture rate.
[0018] In view of this, the present invention provides a pest trapping and collection device for grain storage silos. Through the cooperation of the first through hole, the second through hole, the third through hole and the annular plate, it can trap and collect grain storage pests of different sizes. This solves the problem that since the diameter of the holes on the outer wall of the trapping bottle is the same, pests smaller than the diameter of the holes can enter the trapping bottle, while pests larger than the diameter of the holes cannot enter the trapping bottle smoothly, which directly leads to a limited trapping range and a significant decrease in the capture rate.
[0019] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.
[0020] Example 1: By Figure 1-4 It is known that a pest trapping and collection device for grain storage silos includes a collection bottle 1, a trapping bottle 3 fixedly attached to the upper inner wall of the collection bottle 1, and a bottom plate 2 glued to the bottom of the collection bottle 1. The pest trapping and collection device for grain storage silos also includes a trapping component 4 and an auxiliary component 5. The trapping component 4 is disposed inside the trapping bottle 3; the auxiliary component 5 is disposed inside the collection bottle 1. The trapping component 4 traps and collects pests in grain storage silos of all sizes, and the auxiliary component 5 increases the range of pest trapping. In the specific implementation process, it is worth noting that during assembly, the staff inserts the trapping bottle 3 into the collection bottle 1. After completion, they wrap and seal it together with tape. The collection bottle 1 is then connected to the base plate 2 with hot melt adhesive. The base plate 2 can increase the contact area between the collection bottle 1 and the grain inside the granary, improving stability. The trapping component 4 is used to trap and collect pests in both large and small granaries, and the auxiliary component 5 is used to increase the range of pest trapping.
[0021] Example 2: From Figure 1-4 It is known that the trapping component 4 includes a first through hole 41, a second through hole 42, a third through hole 43, and an annular plate 44. The first through hole 41 is opened on the upper part of the outer wall of the trapping bottle 3. The second through hole 42 is opened on the outer wall of the trapping bottle 3 and is located below the first through hole 41. The third through hole 43 is opened on the outer wall of the trapping bottle 3 and is located below the second through hole 42. There are three annular plates 44, which are respectively adhered to the inner wall of the trapping bottle 3. Through the cooperation of the first through hole 41, the second through hole 42, and the third through hole 43, pests of different sizes can enter the trapping bottle 3, and the annular plates 44 block the three through holes. In the specific implementation process, it is worth noting that the first through hole 41 is designed with a diameter of 1-2mm to capture small pests, such as red flour beetle or sawtooth flour beetle. It has a circular hole structure and there are 20-25 holes. The second through hole 42 is designed with a diameter of 2-3mm to accommodate medium-sized pests, such as corn weevil or rice weevil. There are 15-20 holes. The third through hole 43 is designed with a diameter of 3-4mm to target larger stored grain pests, such as grain borer or large grain beetle. There are 12-15 holes. When the pests approach the device, they enter the trapping bottle 3 through the first through hole 41, the second through hole 42 or the third through hole 43, depending on their size. The pests that enter the trapping bottle 3 cannot escape back out due to the obstruction of the annular plate 44 and then fall into the collection bottle 1, thus realizing the trapping and collection of grain storage pests of different sizes. Furthermore, the auxiliary component 5 includes a box body 51, a cover 52, a sponge 53, and a vertical hole 54. The box body 51 is adhered to the bottom of the inner wall of the collection bottle 1; the cover 52 is inserted into the top of the outer wall of the box body 51; the sponge 53 is placed on the inner wall of the box body 51; and the vertical hole 54 is formed on the surface of the cover 52. In this way, by dripping the attractant into the sponge 53, the attractant molecules are dispersed into the interior of the grain bin through the vertical hole 54. In the specific implementation process, it is worth noting that Sponge 53 uses a high-density absorbent sponge, which is a common industrial absorbent sponge with a thickness of 20mm. It can fully absorb the trapping agent, such as plant-derived insect attractants (such as malt extract, corn flour extract and other environmentally friendly trapping agents). When assembling the device, the workers first attach the hot melt adhesive to the bottom of the collection bottle 1 inside the box 51. Then, the sponge 53 is placed inside the box 51, and the attractant is dripped onto the sponge 53. Finally, the workers put the cover 52 on the box 51. The attractant molecules slowly diffuse into the grain silo through the vertical holes 54 on the cover 52. The chemotaxis of the pests attracts them to the device. Inside the collection bottle 1, the pests are attracted by the continuously emitted attractant odor and are trapped inside the collection bottle 1, thereby achieving the trapping and collection of grain silo pests and achieving the purpose of preventing and controlling stored grain pests. The range of pest trapping is increased by the diffusion of attractant molecules. Furthermore, a battery box 8 is bonded to the top of the outer wall of the trap bottle 3, and a lamp tube 9 is fixed to the bottom of the battery box 8. The lamp tube 9 extends into the interior of the trap bottle 3 through an opening. In the specific implementation process, it is worth noting that the battery box 8 and the lamp tube 9 are electrically connected. The lamp tube 9 is an LED ultraviolet lamp tube, model UV-LED365nm. This wavelength has a strong phototactic attraction to stored grain pests. The power is 0.5W, which is energy-saving and has a long service life (about 50,000 hours). The battery box 8 can be equipped with two AA batteries to provide power to the lamp tube 9. The battery box 8 is equipped with a switch to easily control the opening and closing of the lamp tube 9. When using the device, the staff turns on the lamp tube 9 through the switch on the battery box 8. The lamp tube 9 emits 365nm ultraviolet light, which attracts pests to the device by utilizing their phototaxis, thus achieving the purpose of trapping and collecting pests by using their phototaxis. Furthermore, a drop nozzle 7 is glued to the bottom opening of the trap bottle 3, and the drop nozzle 7 is in the shape of an inverted cone; In the specific implementation process, it is worth noting that the drop nozzle 7 is connected to the bottom opening of the trap bottle 3 by hot melt glue. The drop nozzle 7 has an inverted cone-shaped structure with a taper of 60° and a bottom opening diameter of 5mm, which allows the pests entering the trap bottle 3 to fall smoothly into the collection bottle 1, while effectively preventing the pests from crawling out from the drop nozzle 7. Furthermore, a limiting ring 6 is glued to the upper inner wall of the collection bottle 1, and the inner wall of the limiting ring 6 is attached to the lower outer wall of the trapping bottle 3. In the specific implementation process, it is worth noting that the limiting ring 6 is connected to the collection bottle 1 by hot melt adhesive. When the trapping bottle 3 and the collection bottle 1 are assembled, the trapping bottle 3 comes into contact with the limiting ring 6, which limits and fixes the trapping bottle 3, ensuring that the position of the trapping bottle 3 in the collection bottle 1 is stable, and at the same time making the internal space of the collection bottle 1 suitable.
