DETAILED DESCRIPTION

[0024] The technical solution of the present invention is further elaborated in detail below in conjunction with specific embodiments. The parts of the present invention that are not described and disclosed in detail in the following embodiments should be understood as the prior art known or should be known to those skilled in the art.

[0025] like Figure 1 As shown, the utility model discloses a multifunctional stored grain pest trap, comprising a flying pest trapping component, a grain surface pest trapping component and a grain pile pest trapping component which are arranged in sequence from top to bottom;

[0026] The flying pest trapping assembly includes a vertical mounting rod, an upper sticky plate 2 and a lower sticky plate 5 arranged on the mounting rod, the upper sticky plate 2 and the lower sticky plate 5 are both bowl-shaped and the bowl mouths of the upper sticky plate 2 and the lower sticky plate 5 are opposite, the mounting rod has a stretching section 4 located between the upper sticky plate 2 and the lower sticky plate 5, the stretching section 4 includes a plug-in rod body 401 and a rod sleeve 402, a positioning column 403 is arranged on the rod body 401, a slideway 404 for the positioning column 403 to pass through is provided on the rod sleeve 402, and a positioning groove 4044 is provided on the slideway 404 to locate the relative positions of the upper sticky plate 2 and the lower sticky plate 5.

[0027] like Figure 2 , 3As shown, there are two positioning posts 403 on the stretching section 4 and they are relatively arranged on the outer cylindrical surface of the rod body 401, and the slide 404 includes an entrance section 4041. At the end of the entrance section 4041, there are two slide branches in the same direction as the entrance section 4041, namely a first slide branch 4042 and a second slide branch 4043. The length of the first slide branch 4042 is smaller than that of the second slide branch 4043. A positioning groove 4044 is provided on the first slide branch 4042. When the positioning post 403 is located in the positioning groove 4044, the upper sticky plate 2 and the lower sticky plate 5 are separated, and the pests can move toward the sticky plate under the action of the insect attracting light source, and thus be adhered to the sticky plate. When the positioning post 403 is located at the end of the second slide branch 4043, the upper sticky plate 2 and the lower sticky plate 5 are buckled together to reduce the adhesion of impurities in the warehouse such as dust on the sticky plate, so as not to affect the insect attracting effect.

[0028] The mounting rod has a transparent section 3 for placing an insect-attracting light source, and the transparent section 3 is located between the upper sticky plate 2 and the lower sticky plate 5, and the transparent section 3 is located above the stretching section 4. The transparent section 3 is made of an acrylic plate, which has the advantages of good light transmission, not easy to be damaged, environmentally friendly, and durable. The insect-attracting light source can be an LED lamp, and the LED lamp with a specific wavelength has a more significant trapping effect on specific stored grain pests.

[0029] In other embodiments of the present invention, the transparent section 3 is configured as a hollow core shaft, in which an attractant core such as sex pheromone is placed.

[0030] The mounting rod also has a support section 6, which is located below the stretching section 4, and the lower end of the support section 6 extends out of the lower sticky plate 5, and the lower end of the support section 6 is threadedly connected to the grain surface pest trapping component.

[0031] The upper end of the transparent section 3 has a connecting section extending to the outside of the upper adhesive plate 2, and a hook 1 is arranged at the upper end of the connecting section.

[0032] The connecting section, transparent section 3, stretching section 4 and support section 6 are integrally formed to form a mounting rod, or the connecting section, transparent section 3, stretching section 4 and support section 6 can be formed into a mounting rod in a detachable connection manner such as threaded connection or snap-on connection.

[0033] The grain and flour pest trapping assembly includes a first insect attracting tube 20 and a first insect collecting chamber 11 arranged below the first insect attracting tube 20. A first insect killing chamber 10 is arranged in the first insect collecting chamber 11, and the first insect killing chamber 10 is connected to the inner cavity of the first insect attracting tube 20. The side wall of the first insect killing chamber 10 is provided with a first insect outlet hole 12 connecting the first insect killing chamber 10 and the first insect collecting chamber 11. The side wall of the first insect attracting tube 20 is provided with a first insect attracting hole 9. A first attracting core 19 is arranged in the first insect attracting tube 20. The first attracting core 19 includes a material containing pipe and an attractant arranged in the material containing pipe. The material containing pipe is provided with a first attracting core 19 air hole 8. The smell of the attractant escapes outward through the first attracting core 19 air hole 8 to attract pests to crawl into the first insect attracting tube 20. The specific selection of the attractant is the existing technology, such as sex hormones. The first insect collecting chamber 11 is in the shape of a cone with the small diameter end facing downward. After the grain pile insect attractant assembly is inserted into the grain pile, the cone-shaped first insect collecting chamber 11 can also be inserted into the grain pile relatively smoothly, so as to maintain the stability of the entire insect attractant device.

[0034] A support rod 7 is provided at the top of the first insect attracting tube 20, and a threaded hole is provided on the support rod 7 for the lower end of the mounting rod (i.e., the lower end of the supporting section) to be inserted. The support rods 7 are two horizontally arranged and cross-distributed, and the threaded hole for the lower end of the mounting rod to be inserted is provided at the intersection of the crosses. A gap is left between the lower adhesive plate 5 on the mounting rod and the support rod, so that some pests with a volume larger than the first insect attracting hole 9 can enter the first insect attracting tube 20 through the area formed between the two support rods 7.

[0035] In the present embodiment, the first insect attracting tube 20 is a conical tube with the small diameter end facing upward, and the side wall of the first insect attracting tube 20 is provided with 8 rows of circular first insect attracting holes 9, and the first insect attracting holes 9 are conical holes, and the small diameter end of the conical hole faces the inside of the trap, and the large diameter end faces the outside of the trap, so as to facilitate pests to crawl into the first insect attracting tube 20 and reduce the pests to escape outward, and there are 12 first insect attracting holes 9 in each row, and the large diameter end of each first insect attracting hole 9 has a diameter of about 3.5 mm, and the stored grain pests on the grain surface enter the first insect attracting tube 20 through the first insect attracting holes 9, and the surface of the first insect attracting tube 20 is made of low-carbon steel, and after the low-carbon steel is treated with nitriding or boronizing, the surface has high hardness and toughness, and its corrosion resistance is also significantly improved.

[0036] The bottom of the first insect trapping tube 20 is connected to the insect storage part of the grain surface pest trapping assembly, and the insect storage part includes a first insect collecting chamber 11 and a first insect killing chamber 10. The first insect killing chamber 10 is a bowl-shaped structure with an opening upward. The diameter of the bowl-shaped structure is 210 mm, the height is 35 mm, and the thickness is 4 mm. The stored grain pests fall into the first insect killing chamber 10 through the first insect trapping hole 9. The side wall of the first insect killing chamber 10 is distributed with two rows of circular small holes, each row contains 12 holes, and the radius is about 5 mm. Diatomaceous earth 18 or food inert powder is placed in the central part of the first insect killing chamber 10 to kill the pests that fall into it. The first attractant core 19 above will also attract the pests below and stimulate their movement. The moving pests enter the first insect collecting chamber 11 through the first insect exit hole 12. In addition, the first insect-killing chamber 10 and the first insect-collecting chamber 11 are arranged separately, and the pests in the first insect-killing chamber 10 enter the first insect-collecting chamber 11 through the first insect-exit hole 12, thereby improving the insecticidal efficiency of the insecticide (i.e., diatomaceous earth 18 or food inert powder) in the first insect-killing chamber 10, and preventing the pests from falling directly onto the insecticide. The dead bodies of the pests killed by the insecticide are accumulated on the insecticide, covering the insecticide and thus affecting the subsequent insecticidal effect.

[0037] The first insect collecting chamber 11 is a tapered cylinder that is wide at the top and narrow at the bottom, with an upper diameter of 210 mm, a bottom diameter of 50 mm, a height of 60 mm, and a thickness of 4 mm. When pests enter the first insect collecting chamber 11, they cannot escape due to the closed structure inside, thereby achieving the purpose of collecting pests. The first insect collecting chamber 11 and the first insect killing chamber 10 are made of low carbon steel. At the same time, a layer of polytetrafluoroethylene can be applied on the surface of the first insect collecting chamber 11. Polytetrafluoroethylene has the advantages of good corrosion resistance, acid and alkali resistance, high temperature resistance, and long service life. At the same time, the friction coefficient of polytetrafluoroethylene is relatively low, which makes it more difficult for pests to crawl.

[0038] The grain pile pest trapping assembly includes a second insect trapping tube 21 and a second insect collecting chamber 17 disposed below the second insect trapping tube 21. The second insect killing chamber 15 is located in the second insect collecting chamber 17, and the second insect killing chamber 15 is connected to the inner cavity of the second insect trapping tube 21. The side wall of the first insect killing chamber 10 is provided with a second insect exit hole 14 connected to the second collecting chamber. The side wall of the second insect trapping tube 21 is densely covered with second insect trapping holes 13, which are the main way for pests to enter the trapping device. Since the stored grain pests in the grain pile are generally small in size, with a body length of about 1 to 3 mm, the second insect trapping holes 13 are selected as conical insect entry holes with a diameter of 2 mm. This can improve the trapping efficiency of stored grain pests and reduce the pest escape rate.

[0039] The bottom of the first insect collecting chamber 11 is provided with a downwardly extending external thread section, and the upper end of the second insect attracting tube 21 is provided with an internal thread section used in conjunction with the external thread section, so as to achieve a threaded connection between the grain surface insect attracting assembly and the grain pile insect attracting assembly.

[0040] like Figure 1 As shown, the grain pile pest trapping assembly consists of a second insect collecting chamber 17 and a second insect killing chamber 15. The second insect killing chamber 15 is wrapped in the insect collecting chamber, and at the same time, the second insect collecting chamber 17 is connected to the second insect attracting tube 21 of the grain pile pest trapping assembly by a thread.

[0041] When the pests enter the second insect trapping tube 21 from the second insect trapping hole 13, they will fall into the second insect killing chamber 15 below. The second insect killing chamber 15 is a truncated cone that is wide at the top and narrow at the bottom. The upper diameter of the second insect killing chamber 15 is 45 mm, the bottom diameter is 25 mm, and the height is 17.5 mm. Food inert powder or diatomaceous earth 18 is placed at the bottom of the second insect killing chamber 15 to kill pests. When the pests move, their joints are worn out, causing them to lose water and die, while keeping the environment in the insect killing chamber dry. A circular hole with a diameter of 2 mm is opened on the inclined surface of the second insect killing chamber 15, through which stored grain pests can pass through and fall into the second insect collecting chamber 17. The material of the second insect killing chamber 15 is low carbon steel.

[0042] The pests fall into the second insect collecting chamber 17, and because it is a closed structure, they cannot escape, thereby achieving the purpose of killing the pests. The second insect collecting chamber 17 is a cone with a downward tip, and its large diameter end has a diameter of 50mm, a height of 50mm, and a thickness of 2mm. Two cylinders with a diameter of 1mm and a length of 20mm are arranged cross-connected inside the second insect collecting chamber 17, and a cylinder with a bottom diameter of 2mm, a height of 5mm, and a thickness of 0.5mm is arranged at the center thereof, and an attractant is arranged inside the cylinder as a second attractant core 16. The material of the second insect collecting chamber 17 is selected as an alloy material, and at the same time, a layer of polytetrafluoroethylene can be applied inside to reduce the friction coefficient, protect the internal environment, and extend the service life. Since the pests in the grain pile have the characteristic of drilling holes, the second insect attracting holes 13 densely distributed on the side wall of the second insect attracting tube 21 can allow the pests to drill into the second insect attracting tube 21. In order to improve the insect attracting efficiency, the second attracting core 16 arranged in the second insect collecting chamber 17 can improve the insect attracting efficiency.

[0043] In order to further improve the insect luring efficiency, in other embodiments of the present invention, an attractant core is arranged in the second insect luring tube 21. The attractant core has the same structure as the first attractant core 19, including a material containing tube and an attractant arranged in the material containing tube. The material containing tube is provided with air holes, and the smell of the attractant escapes to the outside through the air holes. The material containing tube is threadedly installed under the support rod at the top of the first insect luring tube 20.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
