Description

Technical Field

[0001] This utility model relates to the field of sweet potato breeding technology, specifically to a sweet potato breeding pest control device. Background Technology

[0002] Sweet potato is a high-yield and adaptable food crop, closely related to industrial and agricultural production and people's lives. Besides being a staple food, sweet potato tubers are also important raw materials for food processing, starch and alcohol manufacturing industries, and the roots, stems, and leaves are excellent animal feed. In sweet potato breeding, sweet potato viruses can have a significant impact, specifically leading to a decrease in yield and quality. Sweet potato viruses can cause yield reductions of 20% to 90%, and in severe cases, even total crop failure. They can also cause variety degeneration. As a vegetatively propagated crop, sweet potato viruses are transmitted from generation to generation through tubers and seedlings, accumulating over the years and leading to variety degeneration.

[0003] Sweet potato virus is mainly transmitted through pests such as aphids and whiteflies. In the current sweet potato breeding process, without protective measures, aphids and whiteflies can easily transmit sweet potato virus to sweet potatoes, causing them to become infected with sweet potato virus disease. This seriously affects the sweet potato breeding process. At the same time, there is also a risk of sweet potato virus transmission between different types of sweet potato breeding materials through pests such as aphids and whiteflies. Summary of the Invention

[0004] This invention addresses the problems in existing sweet potato breeding processes, such as pests easily transmitting sweet potato viruses to breeding materials and the easy cross-transmission of sweet potato viruses between different breeding materials. It provides a sweet potato breeding pest control device that uses an insect-proof net to protect the sweet potato breeding materials, effectively preventing pests from transmitting sweet potato viruses to them, reducing the spread of sweet potato virus diseases during breeding, and minimizing the cross-transmission of sweet potato viruses between different breeding materials under the same environment.

[0005] To achieve the above objectives, the technical solution of this utility model is: a sweet potato breeding insect-proof device, comprising a support frame and arch frames disposed at the top of both ends of the support frame. A first insect-proof net is disposed on the outer side of the arch frames, and an insect-proof mechanism is disposed between the tops of the two arch frames. By covering the outer side of the arch frames with the first insect-proof net, insects can be prevented. At the same time, the insect-proof mechanism also plays a role in preventing insects, thereby protecting the sweet potato breeding material and preventing pests from spreading sweet potato viruses to the sweet potato breeding material.

[0006] The insect-proof mechanism includes a support beam, insect-proof components, and a rotating component. The support beam is connected to two arched frames at both ends. A placement groove is formed at the top of the support beam, and a receiving groove is formed at the placement groove. Two insect-proof components are rotatably mounted in the receiving groove. Each insect-proof component includes a winding shaft and a second insect-proof net. The winding shaft is rotatably mounted in the receiving groove, and the second insect-proof net is wound around the winding shaft. The rotating component drives the insect-proof components to rotate. The receiving groove provides an installation position for the insect-proof components. The rotating component rotates the insect-proof components to facilitate the unfolding of the second insect-proof net, which then protects the sweet potato breeding material from insects, thereby preventing pests from spreading sweet potato viruses to the sweet potato breeding material.

[0007] Several support components are also arranged between the two arch frames. Each support component includes a steel wire rope and fixing members at both ends of the steel wire rope, which are connected to the arch frames. The support components support the second insect-proof net by supporting it with the steel wire rope, so that the second insect-proof net can effectively prevent insects.

[0008] Furthermore, a portal frame is fixedly installed inside the arch frame, and a movable door is rotatably installed at the portal frame. A third insect-proof net is installed on the outside of the movable door. The movable door facilitates the passage of workers through the arch frame, while the third insect-proof net prevents pests from entering the inside of the arch frame through the movable door.

[0009] Furthermore, the rotating assembly includes a driving gear, a driven gear, and a handwheel. A gear groove is provided at the top of one of the arch frames. The driving gear and driven gear are respectively fixedly mounted on the winding shafts of the two insect-proof components. The driving gear and driven gear are meshed together, and both are located inside the gear groove. Through the engagement of the driving gear and driven gear, the winding shafts of the two insect-proof components can rotate simultaneously, causing the second insect-proof nets of both components to unfold to both sides simultaneously.

[0010] Furthermore, one end of the take-up shaft, on which the drive gear is mounted, extends to the outside of the gear groove and is connected to the handwheel. A cover is provided on the top of the arch frame at the position corresponding to the gear groove. The handwheel allows the operator to rotate the take-up shaft, and the cover protects the drive and driven gears inside the gear groove.

[0011] Furthermore, the top of both sides of the support frame are provided with strip-shaped grooves, and several clamping rods are arranged inside the strip-shaped grooves. The clamping rods are in a "W" shape. By arranging the clamping rods inside the strip-shaped grooves, the clamping rods can lock and fix the lower end of the second insect-proof net, thereby preventing the lower end of the second insect-proof net from swinging and affecting the insect-proof effect.

[0012] Furthermore, the top of the arch frame is provided with several arc-shaped protrusions at intervals, and the sides of the arch frame are provided with through holes corresponding to the positions of the arc-shaped protrusions. Through the design structure of the arc-shaped protrusions and the through holes at the arc-shaped protrusions, the steel wire rope, when taut, can contact the second insect-proof net, thus achieving the effect of supporting the second insect-proof net.

[0013] Furthermore, the fixing component includes a threaded cylinder, a tensioning bolt, and a washer. One end of the threaded cylinder is connected to the wire rope, and the other end is inserted into the through hole. The other end of the threaded cylinder is detachably threadedly connected to the tensioning bolt. The threaded connection between the threaded cylinder and the tensioning bolt secures the threaded cylinder in the through hole, allowing the wire rope to be taut and straightened.

[0014] Furthermore, the pad is fitted onto the tension bolt and located on the outside of the arch frame, and the diameter of the pad is larger than the diameter of the through hole. The pad ensures that the wire rope is taut and straight, thus guaranteeing its effective support for the second insect-proof net.

[0015] The beneficial effects of this utility model through the above technical solution are as follows: This utility model has a reasonable structure and good performance. It protects sweet potato breeding materials with an insect-proof net, which can effectively prevent pests from spreading sweet potato viruses to sweet potato breeding materials, reduce the spread of sweet potato virus diseases during the sweet potato breeding process, and reduce the cross-transmission of sweet potato viruses between different sweet potato breeding materials under the same environment.

[0016] This utility model uses a first insect-proof net covering the outside of the arch frame to prevent insects, a second insect-proof net covering the space between two arch frames to prevent insects, and a third insect-proof net covering the outside of the movable door to prevent insects. Through the functions of the first, second, and third insect-proof nets, it can prevent external pests from spreading sweet potato viruses to sweet potato breeding materials, and also prevent the spread of sweet potato viruses carried by the sweet potato breeding materials themselves, thereby reducing the spread of sweet potato virus diseases during sweet potato breeding.

[0017] The steel wire rope in the support component of this invention supports the second insect-proof net, effectively supporting it and ensuring its insect-proof function. The steel wire rope is tightened by fixing members at both ends for easy installation and removal. Furthermore, clamping rods are arranged inside the strip-shaped groove to secure the lower end of the second insect-proof net, preventing it from swaying and affecting its insect-proofing effect.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1-6 As shown, a sweet potato breeding pest control device includes a support frame 1 and arch frames 2 disposed at the top of both ends of the support frame 1. A first insect-proof net 4 is disposed on the outer side of the arch frames 2, and an insect-proof mechanism is disposed between the tops of the two arch frames 2. In this embodiment, the support frame 1 has a square frame structure, the arch frames 2 are arc arch frames, and the first insect-proof net 4 is fixed to the outer side of the arch frames 2 by several bolts and washers. The washers are used to increase the contact area with the first insect-proof net 4 and improve the fixing effect of the first insect-proof net 4. Covering the outer side of the arch frames 2 with the first insect-proof net 4 prevents pests from entering through the arch frames 2 and spreading sweet potato viruses to the sweet potato breeding material.

[0021] The insect-proof mechanism includes a support beam 5, insect-proof components, and a rotating component. The support beam 5 is connected to two arch frames 2 at both ends. A placement groove 6 is provided at the top of the support beam 5, and a receiving groove 7 is provided at the placement groove 6. Two insect-proof components are rotatably arranged in the receiving groove 7. Each insect-proof component includes a winding shaft 8 and a second insect-proof net 13. The winding shaft 8 is rotatably arranged in the receiving groove 7, and the second insect-proof net 13 is wound around the winding shaft 8. The rotating component is used to drive the insect-proof components to rotate. In this embodiment, the size of the placement groove 6 is larger than the size of the receiving groove 7. After the second insect-proof net 13 is wound onto the winding shaft 8, a cover plate can be placed in the placement groove 6. The receiving groove 7 provides space for the winding shaft 8 and the second insect-proof net 13. The rotating component is connected to the winding shaft 8, allowing the winding shafts 8 of both insect-proof components to simultaneously wind or unwind the second insect-proof net 13, with the second insect-proof net 13 of both components unwinding to the sides respectively. In addition, a drainage hole is provided at the bottom of the support beam 5 so that water accumulated in the receiving groove 7 can be discharged through the drainage hole during rainy weather. The length of the receiving groove 7 is greater than the distance between the two arch frames 2, and the width of the second insect net 13 is greater than the distance between the arch frames 2. The purpose is to make the two sides of the second insect net 13 cover the outside of the arch frame 2 so that the arch frame 2 can support the second insect net 13 and improve the insect prevention effect of the second insect net 13.

[0022] Several support components are also arranged between the two arch frames 2. The support components include steel wire ropes 15 and fixing members at both ends of the steel wire ropes 15. The fixing members are connected to the arch frames 2. In this embodiment, there are four support components, with two support components installed on each side of the support beam 5. The support components support the second insect-proof net 13. Through the connection between the fixing members at both ends of the steel wire ropes 15 and the arch frames 2, the steel wire ropes 15 can be tightened and straightened, thereby supporting the second insect-proof net 13 and ensuring that the second insect-proof net 13 can play its role in preventing insects.

[0023] A gate frame 3 is fixedly installed inside the arch frame 2, and a movable door (not shown in the figure) is rotatably installed at the gate frame 3. A third insect-proof net is installed on the outside of the movable door. In this embodiment, the movable door is rotatably connected to the gate frame 3 via a hinge. The design structure of the movable door allows workers to pass through the arch frame 2 easily. The third insect-proof net serves to prevent insects from entering the inside of the arch frame 2 through the movable door, thus preventing external pests from spreading sweet potato viruses to the sweet potato breeding material.

[0024] The rotating assembly includes a drive gear 10, a driven gear 11, and a handwheel 12. One of the arch frames 2 has a gear groove 9 at its top. The drive gear 10 and driven gear 11 are respectively fixedly sleeved on the winding shafts 8 of the two insect-proof components. The drive gear 10 and driven gear 11 are meshed and connected, and both are located inside the gear groove 9. In this embodiment, the gear groove 9 provides an installation position for the drive gear 10 and driven gear 11. The meshing of the drive gear 10 and driven gear 11 allows the winding shafts 8 of the two insect-proof components to rotate simultaneously to wind up or unwind the second insect-proof net 13.

[0025] One end of the take-up shaft 8, on which the drive gear 10 is mounted, extends to the outside of the gear groove 9 and is connected to the handwheel 12. A cover (not shown in the figure) is provided on the top of the arch frame 2 at the position corresponding to the gear groove 9. In this embodiment, the handwheel 12 facilitates the rotation of the take-up shaft 8 by the operator, and the cover protects the drive gear 10 and driven gear 11 inside the gear groove 9, while also preventing water accumulation in the gear groove 9 during rainy weather.

[0026] The top of both sides of the support frame 1 is provided with strip-shaped grooves, and several clamping rods 14 are arranged inside the strip-shaped grooves. The clamping rods 14 are in the shape of a "W". In this embodiment, the clamping rods 14 are made of steel wire. One end of the second insect-proof net 13 is connected to the winding shaft 8. When the second insect-proof net 13 is used for insect prevention, the second insect-proof net 13 covers the two arch frames 2 and the steel wire rope 15, and the lower end of the second insect-proof net 13 extends into the strip-shaped groove. Then, the clamping rods 14 are arranged in the strip-shaped groove. The horizontal part of the clamping rods 14 pushes the second insect-proof net 13 to the side of the strip-shaped groove, thereby realizing the clamping and fixing of the lower end of the second insect-proof net 13, preventing the lower end of the second insect-proof net 13 from swinging and affecting the insect prevention effect of the second insect-proof net 13.

[0027] The top of the arch frame 2 is provided with several arc-shaped protrusions 19 spaced apart, and the side of the arch frame 2 is provided with through holes corresponding to the positions of the arc-shaped protrusions 19. In this embodiment, each arch frame 2 has four arc-shaped protrusions 19. The arc-shaped protrusions 19 ensure that after the fixing member is inserted into the through hole, the wire rope 15 can contact the second insect net 13, thus ensuring that the wire rope 15 can support the second insect net 13.

[0028] The fixing components include a threaded cylinder 16, a tensioning bolt 17, and a washer 18. One end of the threaded cylinder 16 is connected to the wire rope 15, and the other end is inserted into the through hole. The other end of the threaded cylinder 16 is detachably threaded to the tensioning bolt 17. In this embodiment, by inserting the threaded cylinder 16 into the through hole and threading it to the tensioning bolt 17, the two ends of the wire rope 15 are fixed to keep the wire rope 15 taut and straight, thereby ensuring that the wire rope 15 provides support for the second insect net 13.

[0029] The pad 18 is fitted onto the tension bolt 17 and located on the outside of the arch frame 2. The diameter of the pad 18 is larger than the diameter of the through hole. In this embodiment, the pad 18 is fitted onto the tension bolt 17 through its own opening. The tension bolt 17 is threadedly connected to the threaded cylinder 16. The pad 18 fits tightly against the outside of the arch frame 2. By increasing the contact area with the arch frame 2, the effect of fixing both ends of the wire rope 15 is improved, thereby ensuring that the wire rope 15 is taut and straight.

[0030] In use, the first insect-proof net 4 is installed on the outer sides of both arch frames 2 using bolts and washers, and a third insect-proof net is installed on the outer side of the movable door using bolts and washers. Then, the second insect-proof net 13 is placed over the two arch frames 2 and the steel wire rope 15. The worker stands on a ladder or other tool and rotates the winding shaft 8 using the handwheel 12. Because the driving gear 10 and the driven gear 11 are meshed, the two winding shafts 8 rotate simultaneously, so that the second insect-proof net 13 on the two winding shafts 8... 3. The second insect-proof net 13 is unfolded to both sides. During the unfolding process, workers can use tools to pull the lower end of the second insect-proof net 13 to assist in moving it downwards until the lower end of the second insect-proof net 13 moves into the strip groove. Then, a clamping rod 14 is arranged in the strip groove. The horizontal part of the clamping rod 14 pushes the second insect-proof net 13 to the side of the strip groove, thereby clamping and fixing the lower end of the second insect-proof net 13. The two arch frames 2 and the steel wire rope 15 support the second insect-proof net 15. Through the functions of the first insect-proof net 4, the second insect-proof net 13, and the third insect-proof net, it is possible to prevent external pests from spreading sweet potato viruses to sweet potato breeding materials, and also to prevent the spread of sweet potato viruses carried by the sweet potato breeding materials themselves, thereby reducing the spread of sweet potato virus diseases during sweet potato breeding.

[0031] When it is necessary to rewind the two second insect nets 13, remove the clamping rods 14 arranged in the two strip slots, and then the operator can rotate the rewinding shaft 8 in the opposite direction through the handwheel 12. The two rewinding shafts 8 rotate simultaneously to rewind the two second insect nets 13.

[0032] The embodiments described above are merely preferred embodiments of the utility model and are not intended to limit the scope of the utility model. Therefore, all equivalent changes or modifications made to the technical solutions described in the scope of the utility model patent application should be included within the scope of the utility model patent application.
