Description

Technical Field

[0001] This utility model relates to the field of agricultural planting technology, and in particular to a root-knot nematode trapping device for potato planting. Background Technology

[0002] Root-knot nematodes are a common pest in potato cultivation. They invade the potato root system, causing root knots to form and severely affecting potato growth and yield. To control root-knot nematode damage, common methods include chemical pesticide control and physical control. While chemical pesticides can effectively kill nematodes, long-term use can lead to soil pollution and increased nematode resistance. Among physical control methods, trapping devices are a more environmentally friendly option. By placing attractants in the device, nematodes are attracted and captured.

[0003] Existing root-knot nematode trapping devices have some shortcomings. For example, many devices are prone to having their ventilation holes or openings blocked by soil during use, which prevents the attractant's scent from dissipating effectively and reduces the trapping effect. Utility Model Content

[0004] The purpose of this invention is to solve the problem that many existing devices are easily blocked by soil during use, preventing the effective dissipation of the attractant's odor. Therefore, this invention proposes a root-knot nematode trapping device for potato cultivation.

[0005] To achieve the above objectives, the present invention employs the following technology: a root-knot nematode trapping device for potato cultivation, comprising an outer cylinder and an inner cylinder used in conjunction with the outer cylinder. The inner cylinder is inserted into the outer cylinder and fixed by an installation component. The outer cylinder has several through holes symmetrically opened on it, and the outer cylinder is also equipped with a blocking component that can prevent soil from clogging the through holes. A collection box is threadedly installed at the bottom of the inner cylinder, and the inner cylinder has several channels communicating with the through holes.

[0006] As a further description of the above technical solution: the installation assembly includes several arc-shaped plates fixedly installed on the inner cylinder, and several arc-shaped frames fixedly installed inside the outer cylinder, wherein the arc-shaped frames are provided with arc-shaped grooves of the same size as the arc-shaped plates.

[0007] As a further description of the above technical solution: the top of the arc plate is provided with grooves, and the protrusions are set on the top of the arc grooves by springs, and the size of the protrusions is adapted to the grooves.

[0008] As a further description of the above technical solution: the blocking assembly includes several rings fixedly installed on the outside of the outer cylinder, the placement frame is placed inside the outer cylinder, and several rubber blocks are fixedly installed on the placement frame.

[0009] As a further description of the above technical solution: the through hole is located in the middle of the ring, the rubber block is located inside the through hole, and the size of the rubber block is adapted to the through hole.

[0010] As a further description of the above technical solution: the channel includes a connecting pipe installed on the inner cylinder, and a number of elastic elements are fixedly installed on one side of the connecting pipe. The elastic elements are conical and have openings between them.

[0011] As a further description of the above technical solution: a circular plate is fixedly installed at the top of the outer cylinder, and several rods are inserted into the circular plate; a guide rod is fixedly installed on the collection box and is located between several channels.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: The inner cylinder has a channel connected to the through hole, and the channel is equipped with an elastic element to guide root-knot nematodes smoothly into the inner cylinder. At the same time, the attractant in the collection box releases its odor through the through hole and channel, further enhancing its attraction to root-knot nematodes. By setting up a blocking component, soil can be effectively prevented from entering the through hole, ensuring that the through hole is unobstructed, thereby ensuring that the odor of the attractant can be released smoothly, attracting root-knot nematodes into the device and improving the trapping efficiency. The device has a compact design, and when installed near potato roots, it will not cause significant interference to the normal growth of potatoes, while effectively controlling the damage caused by root-knot nematodes and ensuring the healthy growth of potatoes.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Reference Figures 1 to 7 This embodiment provides a root-knot nematode trapping device for potato cultivation, including an outer cylinder 10 and an inner cylinder 11 used in conjunction with the outer cylinder 10. The inner cylinder 11 is inserted into the outer cylinder 10 and fixed by an installation component 12. The outer cylinder 10 has several through holes 13 symmetrically opened. Root-knot nematodes can enter the interior of the inner cylinder 11 through the through holes 13 and channels 16. The outer cylinder 10 is also equipped with a blocking component 14 to prevent soil from clogging the through holes 13. A collection box 15 is threaded onto the bottom of the inner cylinder 11. The collection box 15 is used to store attractants. At the same time, the attractant's scent can be emitted outward through the through holes 13 and channels 16, which has an attracting effect on root-knot nematodes. The inner cylinder 11 is provided with several channels 16 that communicate with the through holes 13.

[0017] In more detail, a circular plate is fixedly installed at the top of the outer cylinder 10, and several rods are inserted into the circular plate. The rods can fix the outer cylinder 10 inserted into the soil. A guide rod is fixedly installed on the collection box 15 and is located between several channels 16. The guide rod can guide the root-knot nematodes, allowing them to crawl downwards along the guide rod.

[0018] Reference Figures 2 to 3 Specifically, in order to prevent soil from clogging the through hole 13, a blocking component 14 is provided. The blocking component 14 includes several rings 141 fixedly installed on the outside of the outer cylinder 10. The rings 141 can play a blocking role. When the soil settles, the rings 141 can block the soil particles. The placement frame 142 is placed inside the outer cylinder 10, and several rubber blocks 143 are fixedly installed on the placement frame 142. By pulling the placement frame 142 upward, the rubber blocks 143 can be taken out from inside the outer cylinder 10.

[0019] In more detail, the through hole 13 is located in the middle of the ring 141, and the ring 141 plays a protective role for the through hole 13. The rubber block 143 is located inside the through hole 13, and the size of the rubber block 143 is adapted to the through hole 13. In the initial state, the rubber block 143 is located inside the through hole 13, thereby blocking the through hole 13. In use, the outer cylinder 10 is inserted near the potato root. At the same time, the ring 141 can block the soil. At the same time, the rubber block 143 can prevent the soil from blocking the through hole 13. Then, the insert rod passes through the circular plate and is inserted into the soil to fix the outer cylinder 10. Then, by pulling the placement rack 142 upward, the placement rack 142 causes several rubber blocks 143 to rise, and the rubber blocks 143 move out of the through hole 13 through deformation, thereby opening the through hole 13. Then, the collection box 15 is rotated out of the inner cylinder 11, and then the attractant is added to the collection box 15. Then, the collection box 15 is reinstalled on the inner cylinder 11, and then the inner cylinder 11 is inserted into the outer cylinder 10. The inner cylinder 11 is rotated so that the inner cylinder 11 and the outer cylinder 10 are fixed by the mounting component 12. At the same time, the channel 16 also corresponds to the through hole 13. The scent of the attractant can be emitted outward through the through hole 13 and the channel 16, which plays an attractive role in attracting root-knot nematodes. The root-knot nematodes can enter the interior of the inner cylinder 11 through the through hole 13 and the channel 16.

[0020] Reference Figures 4 to 6 Specifically, in order to fix the inner cylinder 11 and the outer cylinder 10, an installation assembly 12 is provided. The installation assembly 12 includes several arc-shaped plates 121 fixedly installed on the inner cylinder 11 and several arc-shaped frames 122 fixedly installed inside the outer cylinder 10. The arc-shaped frames 122 have arc-shaped grooves of the same size as the arc-shaped plates 121, so that the arc-shaped plates 121 can rotate into the arc-shaped grooves. After the inner cylinder 11 is inserted into the outer cylinder 10, by rotating the inner cylinder 11, the inner cylinder 11 drives the arc-shaped plates 121 to rotate, thereby causing the arc-shaped plates 121 to rotate into the arc-shaped grooves. Figure 5 As shown.

[0021] In more detail, the top of the arc-shaped plate 121 is provided with grooves, and the protrusion 123 is set at the top of the arc-shaped groove by a spring. The spring's reaction force allows the protrusion 123 to return to its original position, and the size of the protrusion 123 is adapted to the groove so that the protrusion 123 can be inserted into the groove. When the arc-shaped plate 121 rotates into the arc-shaped groove, the arc-shaped plate 121 will also contact the arc surface at the bottom of the protrusion 123. The rotating arc-shaped plate 121 can exert a squeezing effect on the protrusion 123, causing the arc-shaped plate 121 to rise. After the arc-shaped plate 121 merges with the arc-shaped groove, the spring's reaction force allows the protrusion 123 to return to its original position and be inserted into the corresponding groove, thereby limiting the arc-shaped plate 121 and fixing the inner cylinder 11 and the outer cylinder 10.

[0022] In more detail, the channel 16 includes a connecting pipe 161 installed on the inner cylinder 11. Root-knot nematodes can enter the connecting pipe 161 through the through hole 13. Several elastic elements 162 are fixedly installed on one side of the connecting pipe 161. The elastic elements 162 are conical and have openings between them. The root-knot nematodes can then enter the inner cylinder 11 through the openings between the elastic elements 162. The openings formed by the elastic elements 162 can block the root-knot nematodes, preventing them from returning to the soil from the channel 16.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
