Description

Technical Field

[0001] The invention belongs to the technical field of trapping and monitoring devices, and in particular relates to a grassland lepidoptera adult trapping and monitoring device. Background Art

[0002] Grassland is the largest open terrestrial ecosystem in my country. In Qinghai Province alone, which is located in the heart of the Qinghai-Tibet Plateau, the available alpine meadow area in the province reaches 21.4125 million hm2. 2 , accounting for 68% of the province's available grassland area (Bai Haitao et al., 2020). In recent years, with the global climate change, human activities and irrational use of grassland resources, the grassland ecological environment has gradually degraded, creating favorable habitats, oviposition microhabitats and food resources for the occurrence of some grassland pests, resulting in a sharp increase in their occurrence. "Grassland Lepidoptera" refers to Lepidoptera insects found in a specific ecological environment, that is, grassland ecosystems. Lepidoptera is a large order in the class Insecta, which includes butterflies and moths. Its larvae have chewing mouthparts and directly feed on the leaves, stems, buds and roots of pasture grass, which leads to a decrease in the photosynthesis capacity of plants and affects growth and development; some species can also damage plant tissues by rolling leaves, adorn leaves, sheathing, spinning silk webs or drilling into them. Adults mostly use nectar as a nutritional supplement, but some species may indirectly affect plant growth by spreading viruses or serving as virus hosts. The damage of such pests seriously affects the natural grassland vegetation, especially the normal growth and development of pasture, causing the yield and quality to be reduced and damaged to varying degrees. Chemical control is often used as the preferred control method due to its rapid action, significant effect and simple operation. However, with the increase in the frequency and amount of pesticide use, it not only causes ecological environmental pollution, but also affects the health of humans and animals, and even endangers life safety in severe cases. "Public plant protection, green plant protection" is an efficient, healthy and sustainable pest control concept in the current era. However, in the existing technology (publication number CN108887240A, the patent name is a patent application for an intelligent monitoring trap), it includes a trap body, the trap includes a funnel bucket and an insect collection bucket, a top cover is arranged above the funnel bucket, the funnel bucket includes an insect entrance, a funnel and a mounting seat, the insect entrance is installed on the mounting seat through the funnel, the top cover is arranged above the insect entrance, and a hanging handle for hanging the trap is arranged below the top cover, and the mounting seat is detachably connected to the insect collection bucket.

[0008] Preferably, a rotatable rotating ring is coaxially provided at the bottom edge of the top cover, and the rotating ring is provided with a top opening structure, and a crown gear is fixed on the bottom surface above the rotating ring.

[0009] Preferably, a gear is provided on one side of the outer circumference of the rotating shaft and is meshed with a crown gear, and air ducts are extended downward on both sides of the bottom surface of the rotating ring. At the same time, one side of the surface of the air duct is close to the outer circumference of the hanging net, and the air duct close to the outer circumference of the hanging net is provided with exhaust holes.

[0010] Preferably, an air guide ring is fixedly connected to the end of the air duct, the air guide ring and the interior of the air duct are arranged in a hollow structure, and a fan is fixed on one side of the outer peripheral surface of the air guide ring.

[0012] Preferably, a second rotating ring is fixed to the other end of the conduit, and an air outlet is opened downward at the top of the second rotating ring, and the air outlet at the top of the second rotating ring contacts the bottom surface of the bottom box.

[0013] Preferably, a bottom ring is fixed at the bottom edge of the bottom box, and air ducts are evenly distributed above the bottom ring. The air ducts are arranged in an inclined structure, and the openings of the air ducts face the bottom opening of the guide tube.

[0014] Preferably, a flip opening is penetrated through the surface of the bottom ring, and hangers are fixedly connected to both sides of the bottom surface of the flip opening, and a flippable flap is provided between the two hangers, and gear 2 is fixedly provided at one end of the rotating rod, and crown gear 2 located at the bottom opening of rotating ring 2 forms a meshing connection with gear 2.

[0015] The grassland Lepidoptera adult insect trapping and monitoring device of the present invention has the following advantages:

[0016] 1. A grassland lepidopteran adult trapping and monitoring device. When the lepidopteran adults are attracted by the bait and enter the hanging net, when these insects need to be captured for further monitoring, the motor drives the rotating shaft to rotate, driving the winding wheels on both sides to reel up the hanging rope, so that the lifting plate moves upward along the hanging net. As the lifting plate rises, it compresses the space in the hanging net to facilitate personnel to catch insects. At the same time, as the lifting plate moves up, the baffle is pulled by the pull rope fixed to the guide cylinder to seal the through hole, preventing the lepidopteran adults from escaping from the through hole.

[0017] 2. A grassland Lepidoptera adult trapping and monitoring device, when the motor drives the rotating shaft 1 to rotate, the gear 1 on the outer peripheral surface of the rotating shaft 1 drives the crown gear 1, so that the rotating ring 1 rotates accordingly. As the rotating ring 1 rotates, the air ducts on both sides of its bottom surface also begin to rotate, and while the air ducts rotate, the fan located on the outer peripheral surface of the air guide ring starts, and the generated airflow passes through the air guide ring and the air duct, and finally blows to the surface of the hanging net from the exhaust holes on the air duct. In this way, in the process of the lifting plate moving up and down to compress the internal space of the hanging net, the airflow prompts the Lepidoptera adult insects to fly, avoiding the possible damage to the insects caused by the rising of the lifting plate.

[0018] 3. In the grassland lepidopteran adult trapping and monitoring device, when the lepidopteran adult is attracted to the food in the bottom box by the bait, the fan on the outer peripheral surface of the air guide ring is started, and part of the air flow generated enters the duct through the air hole, then flows into the second rotating ring through the duct, and is blown out through the air guide pipe arranged in an inclined shape. Due to the inclined structure of the air guide pipe, the air flow can effectively blow the lepidopteran adult toward the guide tube, thereby assisting in capturing these insects.

[0019] 4. In the grassland lepidoptera adult trapping and monitoring device, after the lepidoptera adult trapping inside the hanging net is completed, the lifting plate moves upward, and the air guide ring rotates together with the air duct. The rotation of the air guide ring drives the duct to rotate, and then the rotating ring 2 rotates accordingly. As the rotating ring 2 rotates, the crown gear 2 set at its bottom engages with the driving gear 2, prompting the flap to flip with the rotating rod as the axis, so that the bait placed on the flap falls down.

[0020] 5. In the grassland lepidoptera adult trapping and monitoring device, when the rotating ring 2 rotates, the crown gear 2 at the bottom drives the flap to flip. At the same time, the crown gear 2 also drives the meshing gear 5 above to rotate, thereby rotating the gear 3 together through the rotating shaft 2. As the gear 3 rotates, it drives the conveyor belt to rotate through the gear 4. In this way, when the flap flips to discharge the bait, the conveyor belt accelerates the falling process of the bait, and the shovel can remove impurities on the surface.

[0041] The disclosure below provides many different embodiments or examples to implement different structures of the embodiments of the present invention. In order to simplify the disclosure of the embodiments of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the embodiments of the present invention. In addition, the embodiments of the present invention can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed.

[0042] like Figure 1-Figure 2 As shown, a grassland lepidoptera adult trapping and monitoring device of the present invention comprises a hanging net 2 for trapping lepidoptera, and a top cover 21 and a bottom cover 22 are connected to the top and bottom of the hanging net 2 respectively, and holes are provided through the surface of the bottom cover 22, through which lepidoptera can fly into the hanging net 2, and a bottom box 3 is relatively arranged below the bottom cover 22, so that a gap can be formed between the bottom box 3 and the bottom of the hanging net 2, and bait is placed inside the bottom box 3, through which lepidoptera can be trapped in the hanging net 2. At the same time, a support frame 1 is placed on one side of the hanging net 2, and the top of the support frame 1 is connected to the top cover 21, so that the hanging net 2 can be suspended in the air. At the same time, a trapping lamp 211 for trapping is fixed on the bottom surface of the top cover 21, and a pheromone box 212 is arranged at intervals on one side of the trapping lamp 211. The interior of the pheromone box 212 is arranged in a hollow structure, and holes are opened on its surface, and corresponding pheromones are placed inside. Therefore, after the trapping lamp 211 emits a specific wavelength, Lepidoptera can be trapped, and the pheromone box 212 further assists the trapping. In addition, a power supply can be arranged on the top of the top cover 21 to power the corresponding equipment.

[0043] A guide cylinder 221 extends upward from the top of the bottom cover 22, and the guide cylinder 221 is set in a gradually tapered structure from the bottom to the top. Therefore, when Lepidoptera adults need to be trapped, the hanging net 2 can be placed through the support frame 1, and then the corresponding bait is added to the inside of the bottom box 3 or through the trapping lamp 211 and the pheromone box 212 set inside the hanging net 2, and then the Lepidoptera are attracted and fly into the inside of the hanging net 2 through the guide cylinder 221. Then the staff can conduct certain monitoring through the hanging net 2, and can open the zipper installed on the surface, catch the Lepidoptera adults and further monitor and observe in detail.

[0044] like Figure 3-Figure 6 As shown, a motor 5 is fixedly arranged on one side above the top cover 21, and a rotating shaft 1 51 for rotation is connected to the power output end of the motor 5, and winding wheels 52 are respectively fixed on both sides of the outer circumference of the rotating shaft 1 51. Therefore, after the motor 5 is running, the winding wheel 52 can be rotated together by the rotation of the rotating shaft 1 51. At the same time, the operation of the motor 5 can be controlled and processed by the central processing unit.

[0045] At the same time, a lifting plate 6 capable of lifting and displacing is provided at the upper opening of the guide cylinder 221, and a suspension rope 61 extends from both sides above the lifting plate 6 toward the winding wheel 52, and one end of the suspension rope 61 passes through the top cover 21 and is wound around the outer peripheral surface of the winding wheel 52. Therefore, when the winding wheel 52 rotates, the suspension rope 61 is wound, and the lifting plate 6 can be continuously moved upward along the inside of the hanging net 2. Then, the space inside the hanging net 2 can be compressed, and it is convenient for the monitoring personnel to grab the lepidopteran adults trapped inside the hanging net 2 after unzipping the zipper on one side of the hanging net 2.

[0046] like Figure 7-Figure 8 As shown, a through hole 62 is penetrated through the surface of the lifting plate 6 and is opposite to the opening of the guide cylinder 221. At the same time, a retraction groove 621 is opened on one side of the opening side wall of the through hole 62, and a baffle 622 is slidably arranged inside the retraction groove 621. The baffle 622 can block the opening of the through hole 62 after sliding displacement, and a spring 623 is fixed between one side of the surface of the baffle 622 and the inner wall of the retraction groove 621. The spring 623 can be stretched as the baffle 622 is displaced.

[0047] A pull rope 222 is extended from the other side of the baffle 622 toward the surface of the guide cylinder 221, and one end of the pull rope 222 is fixedly connected to the surface of the guide cylinder 221. The pull rope 222 is made of elastic material. Therefore, after the Lepidoptera adults are trapped in the hanging net 2 by the bait or by the trapping lamp 211 and the pheromone box 212 set inside the hanging net 2, when the Lepidoptera adults inside the hanging net 2 need to be captured and further monitored in detail, the motor 5 can be operated to rotate the rotating shaft 51, and as the rotating shaft 51 rotates, the winding wheels 52 provided on both sides of the outer circumference can wind the hanging rope 61 around the outer circumference of the winding wheel 52, and then the lifting plate 6 continuously moves upward along the internal space of the hanging net 2, thereby compressing the space inside the hanging net 2 to facilitate personnel to catch the Lepidoptera, and when the lifting plate 6 moves upward, one end of the pull rope 222 is fixedly connected to the surface of the guide cylinder 221, and then the lifting plate 6 moves upward, and the pull rope 222 pulls the baffle 622, and then the baffle 622 can block the through hole 62 to prevent the Lepidoptera from flying out of the through hole 62.

[0048] like Figure 3-Figure 7 As shown, a rotating ring 4 that can rotate is coaxially provided at the bottom edge of the top cover 21. The rotating ring 4 is a top-opening structure, and a crown gear 41 is fixed to the bottom surface above the rotating ring 4.

[0049] The gear 53 provided on one side of the outer circumference of the rotating shaft 51 can be meshed with the crown gear 41, so after the rotating shaft 51 rotates, the crown gear 41 can be rotated through the gear 53. At the same time, air ducts 42 extend downward on both sides of the bottom surface of the rotating ring 4, and one side of the surface of the air duct 42 is close to the outer circumference of the hanging net 2, and the air duct 42 close to the outer circumference of the hanging net 2 is provided with exhaust holes 421.

[0050] An air guide ring 43 is fixedly connected to the end of the air duct 42. The air guide ring 43 and the interior of the air duct 42 are arranged in a hollow structure, and a fan 431 is fixed to one side of the outer circumference of the air guide ring 43, through which the airflow can be blown into the interior of the air guide ring 43. Therefore, after the rotating shaft 51 is rotated by the motor 5, the gear 53 provided on one side of the outer circumference of the rotating shaft 51 can drive the crown gear 41, and then the rotating ring 4 can be rotated. After the rotating ring 4 rotates, the air ducts 42 provided on both sides of its bottom surface can rotate together. At the same time, when the air duct 42 rotates, the fan 431 provided on the outer circumference of its air guide ring 43 can be operated, and then the air flow blown out by the fan 431 can be passed into the air guide ring 43 and the air duct 42, and finally the air flow inside the air duct 42 can be blown toward the surface of the hanging net 2 from the exhaust hole 421, and then when the lifting plate 6 moves upward to compress the internal space of the hanging net 2, the air flow blows the lepidoptera adults, so that the lepidoptera adults can fly, so as to prevent the lifting plate 6 from damaging the lepidoptera adults when moving upward.

[0051] like Figure 5-Figure 10 As shown, a duct 71 is fixedly connected to one side of the bottom surface of the air guide ring 43, and the duct 71 is arranged with an internal hollow structure, and an air hole 432 is opened upward on one side of the bottom surface of the air guide ring 43, and the air hole 432 is communicated with the duct 71, and a rotating ring 2 7 is fixed to the other end of the duct 71, and an air outlet 73 is opened downward on the top of the rotating ring 2 7, and the top air outlet 73 of the rotating ring 2 7 contacts the bottom surface of the bottom box 3.

[0052] A bottom ring 31 is fixed at the bottom edge of the bottom box 3, and air guides 311 are evenly spaced above the bottom ring 31, and the air guides 311 are arranged in an inclined structure, with the opening of the air guides 311 facing the bottom opening of the guide tube 221. Therefore, after the lepidoptera are attracted to the food in the bottom box 3 by the bait, the fan 431 provided on the outer peripheral surface of the air guide ring 43 is operated, and part of the airflow generated by the fan 431 enters the conduit 71 through the air hole 432, and then the airflow enters the rotating ring 27 through the conduit 71, and is blown out through the air guide 311. Since the air guide 311 is arranged in an inclined structure, the airflow will blow the lepidoptera adults to fly in the direction of the guide tube 221, and then can assist in capturing the lepidoptera adults.

[0053] like Figure 9-11As shown, a flipping opening 33 is provided on the surface of the bottom ring 31, and hangers 32 are fixedly connected to both sides of the bottom surface of the flipping opening 33, and a flipping plate 8 that can be flipped is provided between the two hangers 32, and the two ends of the rotating rod 82 at the bottom of the flipping plate 8 are hinged with the hanger 32, and rotate with it as the axis. A gear 2 83 is fixedly provided at one end of the rotating rod 82, and a crown gear 2 72 provided at the bottom opening of the rotating ring 2 7 is meshed with the gear 2 83. Therefore, after the lepidopteran adult insects inside the hanging net 2 are trapped, when the lifting plate 6 moves upward, the air guide ring 43 rotates with the air duct 42. When the air guide ring 43 rotates, the duct 71 is driven to rotate together. As the duct 71 rotates, the rotating ring 2 7 can rotate, and then the crown gear 2 72 provided at the bottom of the rotating ring 2 7 can mesh with the driving gear 2 83, and then the flipping plate 8 can be flipped with the rotating rod 82 as the axis, and then the bait placed on the flipping plate 8 can be flipped and dropped.

[0054] like Figure 11-Figure 14 As shown, when the hanging net 2 is used to trap Lepidoptera adults, the bait is placed above the flap 8. After the hanging net 2 is used to trap, the flap 8 can be flipped over, and the bait on the surface of the flap 8 falls off, but some impurities will remain on the surface of the flap 8. Conveyor racks 84 are fixed on both sides of the flap 8, and a rotatable conveyor belt 81 is sleeved between the two conveyor racks 84. A scraper 85 is located on one side of the surface of the conveyor rack 84, and both ends of the scraper 85 are fixedly connected to the surface of the conveyor rack 84.

[0055] A rotating hole 821 is provided inwardly at the other end of the rotating rod 82, and a rotating shaft 2 9 capable of rotation is provided inside the rotating hole 821. A gear 5 91 and a gear 3 92 are fixed at both ends of the rotating shaft 2 9, and the gear 5 91 is meshed and connected with the crown gear 2 72. A gear 4 93 is meshed and connected below the gear 3 92, and the gear 4 93 is meshed and connected with the conveyor belt 81. Therefore, when the rotating ring 2 7 rotates, the crown gear 2 72 provided at the bottom of the rotating ring 2 7 drives the flap 8 immediately, and then the flap 8 can be turned over. When the crown gear 2 72 rotates, the gear 5 91 meshed above is driven, and then the rotating shaft 2 9 provided on one side of the gear 5 91 can make the gear 3 92 rotate together. After the gear 3 92 rotates, the conveyor belt 81 can be rotated through the gear 4 93, and then the flap 8 is turned over and discharged. At the same time, the conveyor belt 81 further accelerates the drop of the bait, and the scraper 85 can scrape off the surface impurities.

[0056] The working principle of a grassland lepidoptera adult trapping and monitoring device is as follows: after the lepidoptera adult is trapped into the hanging net 2 by the bait or the trapping lamp 211 and the pheromone box 212 arranged inside the hanging net 2, when the lepidoptera adult in the hanging net 2 needs to be captured and further monitored in detail, the motor 5 is operated to rotate the rotating shaft 1 51, and as the rotating shaft 1 51 rotates, the winding wheels 52 arranged on both sides of the outer circumference thereof can wind up the hanging rope 61 and wrap it around the outer circumference of the winding wheel 52, and then the lifting plate 6 continuously moves upward along the internal space of the hanging net 2, and then compresses the space inside the hanging net 2 to facilitate personnel to catch the lepidoptera, and when the lifting plate 6 moves upward, one end of the pull rope 222 is fixedly connected to the surface of the guide cylinder 221, and then after the lifting plate 6 moves upward, the pull rope 222 pulls the baffle 622, and then the baffle 622 can block the through hole 62 to prevent the lepidoptera from flying out of the through hole 62;

[0057] Then, after the rotating shaft 51 is rotated by the motor 5, the gear 53 provided on one side of the outer circumference of the rotating shaft 51 can drive the crown gear 41, and the rotating ring 4 can rotate. After the rotating ring 4 rotates, the air ducts 42 provided on both sides of its bottom surface can rotate together. At the same time, when the air duct 42 rotates, the fan 431 provided on the outer circumference of its air guide ring 43 can be operated, and then the air flow blown by the fan 431 can pass into the air guide ring 43 and the air duct 42, and finally the air flow inside the air duct 42 can be blown to the surface of the hanging net 2 from the exhaust hole 421, and then when the lifting plate 6 moves upward to compress the internal space of the hanging net 2, the air flow blows the lepidopteran adults, so that the lepidopteran adults can fly, so as to prevent the lifting plate 6 from damaging the lepidopteran adults when moving upward;

[0058] Secondly, after the lepidoptera are attracted to the food in the bottom box 3 by the bait, the fan 431 provided on the outer peripheral surface of the air guide ring 43 is in operation, and part of the airflow generated by the fan 431 enters the duct 71 through the air hole 432, and then the airflow enters the rotating ring 27 through the duct 71, and is blown out through the air guide pipe 311. Since the air guide pipe 311 is arranged in an inclined structure, the airflow will blow the lepidoptera adults to fly in the direction of the guide tube 221, and then can assist in capturing the lepidoptera adults;

[0059] After the lepidopteran adults are trapped inside the hanging net 2, when the lifting plate 6 moves upward, the air guide ring 43 rotates together with the air duct 42. When the air guide ring 43 rotates, the guide tube 71 is driven to rotate together. When the guide tube 71 rotates, the rotating ring 2 7 can rotate, and then the crown gear 2 72 provided at the bottom of the rotating ring 2 7 can mesh with the driving gear 2 83, and then the flap 8 can be turned over with the rotating rod 82 as the axis, and then the bait placed on the flap 8 can be turned over and fall;

[0060] Finally, when the rotating ring 2 7 rotates, the crown gear 2 72 provided at the bottom of the rotating ring 2 7 drives the flap 8 immediately, and then the flap 8 can be flipped. When the crown gear 2 72 rotates, it drives the meshing gear 5 91 above. Then, the rotating shaft 2 9 provided on one side of the gear 5 91 can make the gear 3 92 rotate together. After the gear 3 92 rotates, the conveyor belt 81 can be rotated through the gear 4 93. Then, when the flap 8 is flipped to discharge the material, the conveyor belt 81 further accelerates the falling of the bait, and the surface impurities can be removed by the scraper 85.
