Description

Technical Field

[0001] This utility model relates to the field of auxiliary tools for grain storage, specifically a device for trapping grain pests. Background Technology

[0002] In the grain storage sector, the rusty red flour beetle, a common stored-grain pest, poses a serious threat to grain quality and safety. Its rapid reproduction and strong spread mean that a large infestation not only leads to grain clumping and mold, but also significantly reduces its edible and commercial value, causing substantial economic losses to grain storage enterprises.

[0003] Currently, the control of the rusty red flour beetle mainly relies on traditional methods such as chemical fumigation. However, long-term use of chemical agents not only easily leads to pesticide resistance in pests, reducing control effectiveness, but also causes excessive pesticide residues in grains, endangering human health and causing environmental pollution. With increasing public awareness of food safety and environmental protection, this chemical-based control method is no longer sufficient to meet the needs of modern grain storage.

[0004] Physical trapping, as a green and environmentally friendly method of pest control, is gradually gaining attention. However, existing trapping devices have several shortcomings in terms of configuration design, attraction effectiveness, and pest retention. Some trapping devices have a simple external configuration, failing to fully cover different areas such as grain surfaces and piles, resulting in a limited trapping range; the release of attractants is unstable and has a short duration, requiring frequent replacement and increasing maintenance costs; furthermore, the volatility of attractants is poor, resulting in a small attraction range and low trapping efficiency; in addition, trapped red flour beetles easily escape, further affecting the actual application effect of the trapping devices. Utility Model Content

[0005] The present invention aims to provide a grain storage pest trapping device to solve the problems of small attraction range and low trapping efficiency of existing trapping devices.

[0006] To solve the above technical problems, the specific solution adopted by this utility model is as follows: a grain storage pest trapping device, comprising a grain surface trap, a grain pile trap, and an insect collection tube arranged sequentially from top to bottom; the grain surface trap includes an outer shell and an inner shell coaxially distributed, the outer shell includes a cylindrical sidewall and a top plate connected to the upper part of the cylindrical sidewall, the inner shell is cylindrical and installed inside the top plate in a detachable manner, and there is an insect entry gap between the upper end of the inner shell and the top plate; the grain pile trap includes a cylindrical shell with multiple insect entry holes, the upper end of the grain pile trap is connected to the inner shell, and the lower end is open and connected to the insect collection tube; a cylindrical lure placement device is provided inside the grain pile trap, the upper end of the lure placement device is connected to the inner side of the top plate, and a fan is provided inside the lure placement device.

[0007] As a further optimization of the above technical solution: an annular groove is provided on the inner side of the top plate, and at least three hooks that are adapted to the groove are provided on the upper end of the inner shell, and a gap is left between the upper end of the inner shell and the groove on the inner side of the top plate to form the insect entry gap.

[0008] As a further optimization of the above technical solution: both the outer shell and the inner shell are tapered with the large diameter end pointing downwards.

[0009] As a further optimization of the above technical solution: the outer surface of the inner shell has several protrusions for grain storage pests to crawl on.

[0010] As a further optimization of the above technical solution: the lure placement device includes a funnel section and a long pipe section connected sequentially from top to bottom, with the large diameter end of the funnel section facing upwards, and the fan located inside the funnel section. The grain surface trap is equipped with a motor and a power supply for driving the fan to rotate.

[0011] As a further optimization of the above technical solution: the grain pile trap is a conical cylinder with the large diameter end facing upwards, the upper end of which is threaded to the inner wall of the inner shell, and the lower end is threaded to the insect collection tube.

[0012] As a further optimization of the above technical solution: a circular sticky insect plate is set inside the grain pile trap. The inner circular surface of the sticky insect plate abuts against the outer wall of the lure placement device, and the outer circular surface abuts against the inner wall of the grain pile trap.

[0013] As a further optimization of the above technical solution: the insect collecting tube includes an upper cylindrical section and a lower conical section, with the cylindrical section threadedly connected to the lower part of the grain pile trap.

[0014] As a further optimization of the above technical solution: the grain surface trap, grain pile trap, insect collection tube, lure placement device and sticky insect board are all made of blue polyethylene material.

[0015] As a further optimization of the above technical solution: the lure in the lure placement device is composed of a slow-release carrier soaked in an attraction reagent.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention provides additional kinetic energy to the attractant molecules through the airflow generated by the fan's rotation, enabling them to diffuse rapidly and shortening the time it takes for pests to perceive the attraction signal. At the same time, the fan is installed in the funnel section, and the airflow generated is dispersed in all directions along the conical structure. It diffuses upwards through the insect entry gap of the grain surface trap and penetrates into the deep layers of the grain pile trap along the insect entry hole, effectively covering pests active on the grain surface and those hidden deep inside, significantly expanding the spread range of the attractant.

[0018] This invention combines a surface grain trap with a pile grain trap, simultaneously covering both the grain surface and the interior of the pile, thus expanding the trapping range. All components are detachable threaded connections, facilitating easy replacement of the lure. The polyethylene material and miniature motor reduce device cost and energy consumption, making it suitable for large-scale application. The blue polyethylene material utilizes the phototaxis of pests to enhance the attraction effect.

[0019] The sticky insect board can promptly trap pests that enter the device, while the smooth inner wall and conical structure of the insect collection tube further prevent pests from crawling out, thus improving the stability of the trapping process. Attached Figure Description

[0036] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. Parts of this utility model that are not described or disclosed in detail in the following embodiments should be understood as prior art known or should be known by those skilled in the art.

[0037] like Figure 1 As shown, this utility model discloses a grain storage pest trapping device, which includes a grain surface trap, a grain pile trap 6 and an insect collection tube arranged sequentially from top to bottom.

[0038] The grain surface trap consists of an outer shell 1 and an inner shell 2, which are coaxially distributed and used to trap pests in the grain surface area.

[0039] Combination Figure 2 , 3 As shown in Figure 4, the outer shell 1 includes a cylindrical sidewall 101 and a top plate 102 connected to the upper part of the cylindrical sidewall 101. The outer shell 1 is generally a tapered structure with the large diameter end pointing downwards. An annular groove 11 is provided on the inner side of the top plate 102 to provide a positioning structure for the installation of the inner shell 2.

[0040] Combination Figure 5 , 6 As shown in Figure 7, the inner shell 2 is cylindrical and detachably connected to the inside of the top plate 102. The inner shell 2 is also a conical structure with the larger diameter end pointing downwards. The larger diameter end of the inner shell 2 refers to the end with the larger outer diameter. The outer wall of the inner shell 2 is inclined, and the inner wall is a vertical plane. It is a cylinder with the same diameter at both ends. This not only limits the depth of the device inserted into the grain pile, preventing the grain surface trap from inserting into the grain pile, but also improves the overall stability of the device after the grain pile trap is inserted into the grain pile. In addition, the cylindrical inner wall makes it easy to open internal threads to connect the lower grain pile trap.

[0041] An insect-entry channel 8 is provided between the outer shell 1 and the inner shell 2. This insect-entry channel 8 is a conical gap with the larger diameter end pointing downwards. At least three hooks 12 adapted to the groove 11 are provided on the upper end of the inner shell 2. In this embodiment, there are six hooks 12 evenly distributed circumferentially along the upper end of the inner shell 2. The hooks 12 are inserted into the groove 11, and their cooperation with the groove 11 achieves connection with the outer shell 1. The hooks 12 are elongated, and their thickness is the same as or slightly greater than the width of the groove 11. The upper end of the hook 12 extends into the groove 11, and the friction between the hook 12 and the groove 11 achieves a fixed connection between the top plate 102 and the inner shell 2. The length of the hook 12 is greater than the depth of the groove 11. A gap is left between the upper end of the inner shell 2 and the groove 11 on the inner side of the top plate 102, forming an insect-entry gap for pests to enter.

[0042] As another way of setting the hook 12, in order to prevent the hook 12 from falling out of the groove 11, the groove 11 is set as a T-shaped groove. The hook 12 includes a connecting rod and a spherical limiting block set on the connecting rod. The spherical limiting block is made of elastic material and the diameter of the spherical limiting block is larger than the spacing of the opening of the T-shaped groove. After being squeezed, the spherical limiting block enters into the T-shaped groove and resets in the T-shaped groove. The opening of the T-shaped groove restricts the spherical limiting block from falling out in a natural state and can be separated when pulled by an external force, so as to realize the detachable connection between the hook 12 and the top plate 102.

[0043] In addition, the outer surface of the inner shell 2 has several protrusions 13, which provide support for the crawling of stored grain pests and facilitate the entry of pests into the device through the gaps between the pests.

[0044] like Figure 10 , 11 As shown, the grain pile trap 6 is used to trap pests inside the grain pile. Its overall shape is a cone-shaped cylinder with the larger diameter end facing upwards, facilitating insertion into the grain pile and improving the stability of the device within it. Multiple insect inlet holes are provided on the shell. The upper end of the grain pile trap 6 has a cylindrical threaded section with external threads. The inner wall of the inner shell 2 has internal threads that match the external threads at the upper end of the grain pile trap 6, connecting it to the inner wall of the inner shell 2 via threads. The lower end of the grain pile trap 6 is open and connected to the insect collection tube 7 via threads. The detachable structure facilitates later maintenance.

[0045] like Figure 1 , 8 As shown, the grain pile trap 6 is equipped with a circular sticky insect plate 4 and a cylindrical lure placement device 3. The inner circular surface of the sticky insect plate 4 abuts against the outer wall of the lure placement device 3, and the outer circular surface abuts against the inner wall of the grain pile trap 6, which can effectively stick pests entering the device and prevent them from escaping.

[0046] like Figure 1 , 12As shown in Figure 13, the lure placement device 3 extends through both the grain surface trap and the grain pile trap 6, with its upper end connected to the inner side of the top plate 102 via hot melt adhesive. The lure placement device 3 includes a funnel section 301 and a long tube section 302 connected sequentially from top to bottom. The larger diameter end of the funnel section 301 faces upwards, and its surface has a honeycomb mesh structure to facilitate the volatilization of the attractant. The lure placement device 3 is used to place the lure. The surface of the lure placement device 3 has a honeycomb mesh structure to facilitate the volatilization of the attractant. The lure consists of a slow-release carrier soaked in the attractant reagent, which can stably release the attractant components and prolong the action time; alternatively, commercially available lures with existing technology that can volatilize the attractant can also be used.

[0047] like Figure 1 , 14 As shown in Figure 15, to expand the spread range of the attractant, a fan 5 is installed inside the funnel section 301 of the lure placement device 3. The grain surface trap is equipped with an electric motor 9 and a power supply 10 to drive the fan 5. When the fan 5 rotates, it accelerates the airflow inside the device, promoting the diffusion of the attractant to the grain surface and surrounding grain pile, thus improving the attraction efficiency. Specifically, the electric motor 9 is a micro-motor with a casing made of iron metal, offering good impact resistance and durability; the core 901 is made of pure copper, providing stable power output and reducing energy loss and noise. The core 901 passes through a through hole in the top plate, with its lower end extending into the funnel section 301, and the blades of the fan 5 are fixed to the core 901.

[0048] As another connection method between the fan 5 and the motor 9, the end of the motor 9's core 901 is connected to a rotating shaft via a coupling. The rotating shaft and the core 901 are coaxially arranged, and the blades of the fan 5 are fixed on the rotating shaft. When the motor 9 is powered on, the rotation of the core 901 directly drives the blades of the fan 5 to rotate, thereby accelerating the volatilization and diffusion of the attractant in the attractant placement device 3. The power supply 10 is powered by a battery box, which facilitates the use of the device in grain depot environments without external power sources.

[0049] like Figure 1 , 9 As shown, the insect collecting tube 7 is used to collect the attracted pests, and includes an upper cylindrical section 701 and a lower conical section 702. The cylindrical section 701 has internal threads, which connect to the external threads at the bottom of the grain pile trap 6. The inner wall of the cylindrical section 701 is smooth to prevent pests from crawling out. The conical section 702 facilitates the insertion of the device into the grain pile and improves the stability of the device in the grain pile.

[0050] The grain surface trap, grain pile trap 6, insect collection tube 7, lure placement device 3, and sticky insect board 4 are all made of blue polyethylene. Studies have shown that the rusty red flour beetle exhibits a clear phototaxis behavior towards blue light, and the blue material can enhance its attractiveness to pests; moreover, polyethylene is inexpensive and easy to process, and high-density polyethylene has good thermal, electrical, and mechanical properties, making it suitable for long-term use in grain storage environments.

[0051] The structure of this utility model will be further described below as a specific embodiment, in conjunction with specific dimensions:

[0052] The storage pest trapping device of this utility model is assembled from top to bottom as follows: grain surface trap, grain pile trap 6, and insect collection tube 7.

[0053] The outer shell 1 of the grain surface trap has a top diameter of 10cm, a bottom diameter of 16cm, and a height of 5cm. The inner side of the top plate 102 has an annular groove 11, 0.2cm wide and 0.3cm deep. The inner shell 2 has an upper diameter of 8.8cm, a lower diameter of 14.1cm, and a height of 4cm. Its top edge has six hooks 12, each 1cm high and 0.2cm wide. These hooks 12 engage with the groove 11 to create an entry gap for pests. The protrusions 13 on the outer surface of the inner shell 2 guide pests to crawl into this entry gap.

[0054] The grain pile trap 6 has a top diameter of 8.4 cm, a bottom diameter of 2 cm, and a height of 23 cm. Its surface is evenly distributed with 0.25 cm diameter entry holes to facilitate insect entry into the grain pile. The internal sticky insect plate 4 is a hollow circular plate with an outer diameter of 8.4 cm. Its inner diameter matches the diameter of the long tube section 302 of the lure placement device 3, effectively trapping insects.

[0055] The lure placement device 3 has a top diameter of 7cm, a bottom diameter of 2cm, and a height of 25cm. A PVC fan 5 is installed inside the funnel section 301. The motor 9 is a cuboid structure with a total length of 2.0cm, a width of 1.5cm, and a height of 2.7cm. The mechanism 901 has a total length of 3.5cm and is connected to a battery box with a length of 6cm, a width of 3cm, and a height of 1.5cm, providing 1-6V voltage to drive the fan 5 to rotate at a speed of 17000-18000r / min, accelerating the evaporation of the attractant.

[0056] The cylindrical section 701 of the insect collecting tube 7 has a bottom diameter of 2.5cm and a height of 4cm, while the conical section 702 has a height of 2cm. It is connected to the lower part of the grain pile trap 6 by threads, and the smooth inner wall can prevent pests from escaping.

[0057] When in use, the slow-release carrier soaked in the attractant is placed into the lure placement device 3. The device is inserted into the grain pile through the conical section 702 of the insect collection tube 7. The power switch 10 is turned on to start the fan 5. The rusty red flat grain beetle on the grain surface and in the grain pile is attracted by the attractant and enters the device through the insect entry gap or insect entry hole. It is then stuck to the sticky insect board 4 or falls into the insect collection tube 7, achieving efficient trapping.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
