Description

Technical Field

[0001] This invention relates to the field of trapping devices, and more particularly to a field collection device for sweet potato weevils. Background Technology

[0002] Sweet potato weevils are a major pest that primarily damages sweet potato crops. Both their larvae and adults cause serious damage. The larvae bore into the sweet potato tubers, creating tunnels that affect the appearance and quality of the sweet potatoes, reducing their commercial value. Furthermore, affected sweet potatoes are susceptible to secondary infections by bacteria and fungi, further exacerbating the losses. The adults weaken the plant's growth by feeding on the leaves and stems. Therefore, effectively controlling sweet potato weevils is crucial for ensuring the yield and quality of sweet potatoes.

[0003] Traditional methods for controlling sweet potato weevils mainly include chemical pesticide spraying, physical trapping, and biological control. In recent years, attractants have been widely used as an efficient and environmentally friendly pest control method. Attractants usually contain insect pheromones or other attractive chemical substances that can specifically attract target pests, thereby achieving precise killing. Compared with traditional methods, attractants can specifically attract target pests and reduce the impact on non-target organisms.

[0004] However, existing attractant application equipment struggles to achieve uniform coverage in irregular or large-area farmland with its small spraying range. In particular, the effectiveness of attractants may be further limited in environments with significant wind direction changes or complex terrain. Summary of the Invention

[0005] The purpose of this invention is to solve the problem in the prior art that it is difficult to achieve uniform coverage in irregular or large-area farmland with a small spraying range, especially in environments with large wind direction changes or complex terrain, where the effect of attractants may be further limited. Therefore, this invention proposes a field collection device for sweet potato weevils.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A field collection device for sweet potato weevils includes a collection box, on which a trap shell is fixedly installed. The trap shell has equidistant mounting grooves on its outer circumference. One end of each mounting groove near the collection box has a trapping hole that communicates with the interior of the trap shell. A protective cover is slidably mounted on the trap shell. A piston is fixedly installed inside the trap shell, and the protective cover is slidably connected to the piston. The device also includes a trapping tube rotatably installed in the mounting groove, one end of which is fixedly connected to the piston, and an attractant release assembly fixedly installed on the collection box and connected to the piston via a flexible hose.

[0008] To release the attractant in the form of a spray, preferably, the attractant release assembly includes an attractant storage tank and an air pump fixedly installed on the collection box, and both the attractant storage tank and the air pump are fixedly connected to the piston section by a connecting pipe; wherein, a metering pump is fixedly installed on the connecting pipe for connecting the attractant storage tank and the piston section.

[0009] To ensure uniform mixing of the attractant and the airflow, and to utilize air pressure to lift the protective cover and expose the trapping tube, the piston portion further includes a sealing cylinder fixedly installed inside the trapping shell, the trapping tube being fixedly connected to the sealing cylinder, and a sealing gasket slidably installed inside the sealing cylinder. A first support rod is fixedly connected between the sealing gasket and the protective cover. A first spring is sleeved on the first support rod, and the two ends of the first spring are fixedly connected to the inner top wall of the protective cover and the top surface of the sealing cylinder, respectively.

[0010] To rotate the trapping tube and increase the spray range of the attractant, preferably, a connecting pin is rotatably installed in the mounting groove, a first gear is fixedly installed on the connecting pin, a clamping plate is fixedly installed on the connecting pin, the trapping tube is clamped and installed on the clamping plate, and a first rack that meshes with the first gear is fixedly installed on the inner wall of the protective cover; wherein, a rectangular through groove is formed on the inner wall of the mounting groove, and the first gear is installed through the rectangular through groove.

[0011] In order to clamp the trapping tube and keep its interior closed when stored, a first abutment plate is fixedly installed on the inner wall of the mounting groove. When the clamping plate is parallel to the mounting groove, the trapping tube is clamped between the clamping plate and the first abutment plate.

[0012] To provide adaptive pressure to the trap tube in the closed state, the clamping plate is further equipped with symmetrically arranged adjusting pins. A second abutment plate is fixedly installed on the side of the adjusting pins near the trap tube. A second spring is sleeved on the adjusting pin, and the two ends of the second spring are fixedly connected to the top of the adjusting pin and the clamping plate, respectively.

[0013] To collect the sweet potato ant weevils that have entered the trap shell, the sweet potato ant weevil field collection device further includes a collection component for guiding the sweet potato ant weevils into the collection box and where they remain in the collection area. The collection component includes a baffle fixedly connected to the inner wall of the collection box, the baffle having a circular through groove in the center, and an ant-receiving platform adapted to the baffle. A second support rod is fixedly installed on the ant-receiving platform, and a second rack is fixedly installed on the second support rod and meshes with the first gear.

[0014] To further drive away the sweet potato weevils that have landed on the ant-falling platform, a bushing is installed on the second support rod via a bearing. A second gear and an L-shaped lever are fixedly installed on the bushing. A motor is fixedly installed on the second support rod, and a third gear that meshes with the second gear is fixedly installed at the output end of the motor.

[0015] To further prevent the accumulation of sweet potato ants, the ant-receiving platform is further equipped with a first comb tooth, which is arranged in an arc and distributed equidistantly around the center of the ant-receiving platform. A second comb tooth is fixedly installed on the L-shaped lever, with the first comb tooth and the second comb tooth spaced apart.

[0016] To accommodate field placement requirements, preferably, the collection box has a mounting sleeve on the side closest to the ground, a support leg is slidably mounted inside the mounting sleeve, and a locking bolt for fixing the support leg is rotatably mounted on the mounting sleeve.

[0017] Compared with the prior art, the present invention provides a field collection device for sweet potato weevils, which has the following beneficial effects:

[0018] 1. This field collection device for sweet potato ants and weevils uses a metering pump to precisely control the flow rate and release rate of the attractant. Combined with an air pump, it generates a stable airflow, which fully mixes the attractant with the air and then evenly disperses it into the surrounding environment through the trapping tube. This expands the effective range of the attractant and improves its diffusion ability in complex environments. At the same time, when the device is turned on, the motor-driven collection components form a dynamic cleaning mechanism, pushing and removing the sweet potato ants and weevils until they fall into the collection box, preventing them from escaping.

[0019] 2. This sweet potato ant weevil field collection device effectively prevents the trapping agent mixture from leaking directly from the trapping tube during the rising stage of the protective cover by the cooperation of the clamping plate and the first abutment plate, as well as the design of the adjusting pin and the second abutment plate. This ensures sufficient internal pressure and a clean and stable external environment. Attached Figure Description

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0037] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0038] Example 1:

[0039] Reference Figures 1-6 A field collection device for sweet potato ants includes a circular collection box 1 with a hinged door 104 for periodically cleaning the sweet potato ants inside. A trap shell 2 is fixedly installed on the collection box 1. The trap shell 2 has equidistant mounting grooves 201 on its outer circular surface. A trapping hole 202, which communicates with the inside of the trap shell 2, is opened at one end of the mounting groove 201 near the collection box 1. A protective cover 3 is slidably installed on the trap shell 2. A piston part 4 is fixedly installed inside the trap shell 2. The protective cover 3 is slidably connected to the piston part 4. The device also includes a trapping tube 5 rotatably installed in the mounting groove 201, one end of which is fixedly connected to the piston part 4. An attractant release component 6 is fixedly installed on the collection box 1 and connected to the piston part 4 via a hose.

[0040] When this sweet potato ant weevil field collection device is in use, the attractant release component 6 releases attractant into the trap shell 2 at preset time intervals and dosages. The attractant is transmitted to the piston part 4 through a hose and dispersed into the surrounding environment through the trap tube 5. Through the guidance and diffusion effect of the trap tube 5, the attractant can be evenly distributed to a wider area. Sweet potato ants attracted by the attractant will enter the trap shell 2 through the trap hole 202 and fall into the collection box 1. When the number of pests in the collection box 1 reaches a certain amount, the user can open the collection box 1 to remove and clean them.

[0041] It should be noted that a duckbill tube 204 is installed inside the trapping hole 202, so that the sweet potato ant weevil can only enter through the trapping hole 202 and cannot leave.

[0042] Reference Figure 1 and Figure 3 and Figure 4The attractant release assembly 6 includes an attractant storage tank 601 and an air pump 602 fixedly installed on the collection box 1. The attractant storage tank 601 is used to store chemical attractants, such as pheromones or other attractive substances. The attractant storage tank 601 has an inlet for adding attractive substances and is sealed with a sealing cap. It is replenished periodically as needed. Both the attractant storage tank 601 and the air pump 602 are fixedly connected to the piston part 4 by a connecting pipe 603. A metering pump is fixedly installed on the connecting pipe 603 that connects the attractant storage tank 601 and the piston part 4 to precisely control the flow rate of the attractant. The metering pump can adjust the release rate of the attractant according to preset parameters to ensure that the dosage is consistent each time it is sprayed.

[0043] When the device is started, the air pump 602 starts working, generating airflow that enters the piston section 4 through the connecting pipe 603. At the same time, the metering pump draws attractant from the attractant storage tank 601 at a set rate and delivers it to the piston section 4 through the connecting pipe 603. The piston section 4 receives the airflow from the air pump 602 and the attractant from the metering pump. After mixing, the attractant is evenly distributed to the surrounding environment through the trapping tube 5. Because the air pump 602 provides a stable airflow, the attractant can maintain an effective concentration at a long distance, attracting sweet potato ants from afar.

[0044] Reference Figure 2 and Figure 3 and Figure 4 The piston part 4 includes a sealing cylinder 401 fixedly installed inside the trap shell 2, providing a closed space for containing a mixture of attractant and gas. The trap tube 5 is fixedly connected to the sealing cylinder 401, serving as an outlet channel for the attractant and gas mixture, which can be evenly dispersed into the surrounding environment to attract sweet potato ants. The piston part 4 also includes a sealing pad 402 slidably installed inside the sealing cylinder 401. A first support rod 403 is fixedly connected between the sealing pad 402 and the protective cover 3. A first spring 404 is sleeved on the first support rod 403. The two ends of the first spring 404 are fixedly connected to the inner top wall of the protective cover 3 and the top surface of the sealing cylinder 401, respectively. After the air pump 602 stops working, it can push the sealing pad 402 downward to reset, ready for the next spray.

[0045] A connecting pin 7 is rotatably installed in the mounting slot 201. A first gear 8 is fixedly installed on the connecting pin 7. A clamping plate 9 is fixedly installed on the connecting pin 7. The trapping tube 5 is clamped and installed on the clamping plate 9. A first rack 10 that meshes with the first gear 8 is fixedly installed on the inner wall of the protective cover 3. A rectangular through slot 203 is opened on the inner wall of the mounting slot 201. The first gear 8 is installed through the rectangular through slot 203.

[0046] When the air pump 602 is started, the generated airflow enters the sealing cylinder 401 through the connecting pipe 603, pushing the sealing gasket 402 to move upward. At the same time, the upward-moving sealing gasket 402 drives the protective cover 3 to move upward through the first support rod 403. When the protective cover 3 slides, the first rack 10 pushes the first gear 8 to rotate. The rotation of the first gear 8 is transmitted to the clamping plate 9 through the connecting pin 7, so that it rotates synchronously, thereby adjusting the angle of the trapping tube 5 from being stored in the mounting groove 201 to being perpendicular to the mounting groove 201, thereby optimizing the diffusion mode of the attractant and improving the capture efficiency.

[0047] It should be noted that the opening of the protective cover 3 is exposed by the first rack 10. This way, after the protective cover rises to expose the trapping tube 5, the first rack 10 will contact the first gear 8 to drive the trapping tube 5 to rotate. At the same time, with the support of the first rack 10, the trapping hole 202 is always exposed, which facilitates the entry of sweet potato ant weevils.

[0048] During the operation of the air pump 602, the attractant mixture leaks from the trapping tube 5, contaminating the trapping shell 2 and causing insufficient pressure in the piston section 4. A first abutment plate 11 is fixedly installed on the inner wall of the mounting groove 201. When the clamping plate 9 is parallel to the mounting groove 201, the trapping tube 5 is clamped between the clamping plate 9 and the first abutment plate 11, ensuring the stability and sealing of the trapping tube 5 and preventing leakage of the attractant mixture. Furthermore, symmetrically arranged adjusting pins 901 are slidably installed on the clamping plate 9 to... A second abutment plate 902 is fixedly installed on the side of the adjusting pin 901 near the trapping tube 5. A second spring 903 is sleeved on the adjusting pin 901. The two ends of the second spring 903 are fixedly connected to the top of the adjusting pin 901 and the clamping plate 9, respectively. The second abutment plate 902 can apply additional pressure to the trapping tube 5 according to the moving position of the adjusting pin 901, further enhancing the clamping effect. The function of the second spring 903 is to provide constant pressure to ensure that the second abutment plate 902 always maintains an appropriate clamping force on the trapping tube 5.

[0049] When the air pump 602 starts, the generated airflow enters the sealing cylinder 401 through the connecting pipe 603, pushing the sealing gasket 402 upward. The upward movement of the sealing gasket 402 drives the protective cover 3 upward via the first support rod 403. Simultaneously, the attractant enters the sealing cylinder 401 from the attractant storage tank 601 through a metering pump and mixes thoroughly with the air to form a uniform aerosol. When the protective cover 3 slides, the first rack 10 drives the first gear 8 to rotate. The rotation of the first gear 8 is transmitted to the connecting pin 7. The clamping plate 9 rotates synchronously, changing the angle of the trapping tube 5 from being contained within the mounting groove 201 to being perpendicular to it. This optimizes the diffusion pattern of the attractant and improves capture efficiency. When the clamping plate 9 is parallel to the mounting groove 201, the trapping tube 5 is firmly clamped between the clamping plate 9 and the first abutment plate 11, ensuring the stability and sealing of the trapping tube 5 and preventing leakage of the attractant mixture. The design of the adjusting pin 901 and the second abutment plate 902 further enhances the clamping effect. The second abutment plate 902 applies additional pressure to the trapping tube 5 according to the movement position of the adjusting pin 901, while the second spring 903 provides constant pressure, ensuring that the second abutment plate 902 always maintains an appropriate clamping force on the trapping tube 5. Even when the air pump 602 is not operating, the trapping hole 202 remains exposed under the support of the first rack 10, facilitating the entry of the sweet potato ant weevil.

[0050] Example 2:

[0051] Reference Figure 4-6 A field collection device for sweet potato ants also includes a collection component 12, which guides the sweet potato ants into the collection box 1 and stays in the collection area. The collection component 12 includes a baffle 1201 fixedly connected to the inner wall of the collection box 1. The baffle 1201 has a circular through groove 1202 in the center and an ant-receiving platform 1203 adapted to the baffle 1201. A second support rod 1204 is fixedly installed on the ant-receiving platform 1203. A second rack 1205 that meshes with the first gear 8 is fixedly installed on the second support rod 1204.

[0052] During the rotation of the first gear 8, the meshing second rack 1205 is driven to move in the opposite direction to the first rack 10. The second rack 1205 drives the second support rod 1204 and the ant-catching platform 1203 to move towards the bottom of the collection box 1, so that the ant-catching platform 1203 is located below the baffle 1201, which facilitates the collection of sweet potato ants that fall on the ant-catching platform 1203 into the collection box 1 below the baffle 1201.

[0053] A bushing 1206 is mounted on the second support rod 1204 via a bearing. A second gear 1207 and an L-shaped lever 1208 are fixedly mounted on the bushing 1206. A motor 1209 is fixedly mounted on the second support rod 1204. A third gear 1210, which meshes with the second gear 1207, is fixedly mounted at the output end of the motor 1209. Furthermore, a first comb tooth 1211 is fixedly mounted on the ant-receiving platform 1203. The first comb tooth 1211 is arranged in an arc and is equidistantly distributed around the center of the ant-receiving platform 1203. A second comb tooth 1212 is fixedly mounted on the L-shaped lever 1208. The first comb tooth 1211 and the second comb tooth 1212 are spaced apart.

[0054] When motor 1209 starts, its output drives the third gear 1210 to rotate. The third gear 1210 meshes with the second gear 1207, causing the second gear 1207 to rotate accordingly. The second gear 1207 is fixed on the bushing 1206, so the bushing 1206 also rotates synchronously. As the bushing 1206 rotates, the L-shaped lever 1208 also rotates. During rotation, the second comb tooth 1212 on the L-shaped lever 1208 interacts with the fixed first comb tooth 1211. This forms a dynamic cleaning mechanism. When the L-shaped lever 1208 rotates, the second comb tooth 1212 passes through the gap between the first comb tooth 1211, pushing and removing the sweet potato ant weevils that are stuck on the ant-receiving platform 1203. Since the first comb tooth 1211 is arranged in an arc shape, the area between the first comb tooth 1211 and the L-shaped lever 1208 gradually shrinks when the L-shaped lever 1208 moves. The sweet potato ant weevils will be driven to the edge of the ant-receiving platform 1203 until they fall into the collection box 1.

[0055] Example 3:

[0056] Reference Figure 1 and Figure 3 The collection box 1 has a mounting sleeve 101 on the side near the ground. A support leg 102 is slidably mounted inside the mounting sleeve 101. A locking bolt 103 for fixing the support leg 102 is rotatably mounted on the mounting sleeve 101.

[0057] When installing or adjusting a field collection device for sweet potato ants, first loosen the locking bolt 103. Then, according to the actual terrain, manually slide the support leg 102 up and down to adjust its extension length so that the collection box 1 is placed horizontally and stably on the ground. After the support leg 102 is adjusted to the appropriate height, tighten the locking bolt 103 to firmly fix the support leg 102 in the current position. By adjusting the height of each support leg 102, it can adapt to uneven terrain and ensure that the entire device can remain horizontal and stable under any circumstances, making it more suitable for field environments.

[0058] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
