Description

Technical Field

[0001] This invention belongs to the field of pest and disease control technology, and specifically relates to a device for controlling pine wilt disease. Background Technology

[0002] Pine wilt disease, also known as pine tree cancer, is an invasive quarantine forest pest that can cause devastating damage to pine trees. In my country, the pine sawyer beetle is its main vector insect. It is highly pathogenic, causing rapid host mortality; it spreads quickly and often unexpectedly, making control extremely difficult once it occurs. After pine trees are infected with pine wilt disease, the thin-walled cells and epithelial cells of the resin ducts are destroyed and die, leading to water loss, reduced transpiration, and a sharp decrease or cessation of resin secretion. This results in significant economic losses to forestry resources. Therefore, controlling the spread of the pine sawyer beetle is crucial to preventing the further spread of pine wilt disease.

[0003] Currently, the control of the pine sawyer beetle mainly relies on traps. These traps exploit the beetle's tendency to feign death upon colliding with objects. Bait is used to lure the beetle into the trap by striking the insect-blocking plate on the trap, causing it to fall into the collector. However, the collector does not have an escape prevention function, so existing traps cannot guarantee that all pine sawyer beetles that fall into the collector will not fly out again, resulting in poor control effectiveness. Summary of the Invention

[0004] The present invention aims to provide a device for controlling pine wood nematodes, in order to solve the problem that existing traps do not have an escape prevention function, and the lured pine sawyer beetles can easily fly out again, resulting in poor control effect.

[0005] This solution provides a pine wilt nematode control device, comprising a trapping tube and an insect collector. The insect collector is located below the trapping tube, which contains an inner tube for holding attractants. The trapping tube has several attractant openings. The inner tube is rotatably connected to the trapping tube and is connected to a drive unit that drives its rotation. The outer wall of the inner tube is also provided with several pushing blades. Multiple insect-blocking blades with elastic deformation characteristics are arranged in a ring around the inner side of the attractant openings. The ends of the multiple insect-blocking blades away from the attractant openings approach each other to form an escape-proof opening. The diameter of the escape-proof opening is smaller than the diameter of the attractant opening.

[0006] During the rotation of the inner cylinder, when the pushing blades and the insect-blocking blades overlap, the pushing blades squeeze and bend the insect-blocking blades. After the pushing blades and the insect-blocking blades are completely intersected, the insect-blocking blades recover under their elasticity and form an escape-proof opening again.

[0007] The working principle of this scheme is as follows: The attractant in the inner cylinder emits a scent that overflows from the attraction port. Attracted pine beetles enter through the attraction port. Because multiple insect-blocking leaves, with their ends furthest from the attraction port, converge to form an escape-proof opening, the space in front of the pine beetle becomes increasingly narrow after entering. When the pine beetle senses the surrounding insect-blocking leaves, it is difficult for it to turn around and fly away, thus becoming stuck in the escape-proof opening. As the inner cylinder rotates, the pushing leaves overlap with the insect-blocking leaves, causing the pushing leaves to bend and compress the insect-blocking leaves. At this point, the pine beetle stuck in the escape-proof opening is pushed completely into the trapping cylinder and falls into the insect collector below under the influence of gravity.

[0008] After the pushing blades and the insect-blocking blades completely intersect, the insect-blocking blades recover under their elasticity and form an escape-proof opening again. The pine beetle that wants to fly out of the escape-proof opening can fly out because the escape-proof opening is relatively narrow. Secondly, due to the interference of the pushing blades during the rotation of the inner cylinder, the pine beetle cannot distinguish the direction and has difficulty finding the escape-proof opening. Therefore, even the smaller pine beetles will become tired due to the repeated interference of the rotating pushing blades and eventually become exhausted and stay in the insect collector.

[0009] The beneficial technical effects of this solution are: it can effectively prevent pine sawyer beetles from flying out of the escape-proof opening. The beetles can only get stuck at the escape-proof opening and wait for the pushing leaves to push them into the trap. Once inside the trap, it is almost impossible for the beetles to fly out again. Therefore, the pine sawyer beetle control device of this solution has a very good escape-proof effect and improves the trapping efficiency of pine sawyer beetles.

[0010] Furthermore, the edge of the pushing blade is provided with comb teeth, and when the pushing blade overlaps with the insect-blocking blade, the insect-blocking blade slides between the comb teeth. The comb teeth entering between the insect-blocking blades can better ensure that the pine beetle stuck in the escape prevention opening is brushed and squeezed into the trap tube.

[0011] Furthermore, the driving component is selected from gear transmission or belt transmission, and the power source of the driving component is electrical energy, which is converted and stored through solar energy and / or wind energy. Because this device is used outdoors, it utilizes the natural conditions of outdoor environments, such as wind and the ability to store solar energy under sunlight, to convert wind energy and / or solar energy into electrical energy, thereby driving the gear transmission or belt transmission and causing the inner cylinder to rotate.

[0012] Furthermore, the inner cylinder has a plurality of venting holes evenly distributed on its wall, with a venting hole diameter of 0.2–0.4 cm. This helps the attractant in the inner cylinder to release its attractant odor evenly and persistently.

[0013] Furthermore, the insect-blocking leaf is in the shape of an equilateral triangle.

[0014] Furthermore, the insect-blocking leaves are made of rubber cut from rubber.

[0015] Furthermore, the top of the trapping tube is detachably connected to a top cover, and a partition is provided inside the top cover. The inner tube is rotatably connected to the partition via ball bearings, and the outer wall of the top cover is provided with a rainproof eave that extends beyond the outer wall of the trapping tube.

[0017] Figure 2 This is a front view of the inner cylinder and extrusion blade assembly in Embodiment 1 of the pine wood nematode control device of the present invention. Detailed Implementation

[0018] The following detailed description illustrates the specific implementation method:

[0019] The reference numerals in the accompanying drawings include: 1. Top cover; 2. Rainproof eaves; 3. Trapping tube; 4. Insect collector; 5. Solar panel; 6. Partition; 7. Motor; 8. Gear; 9. Shaft; 10. Gear ring; 11. Sealing door; 12. Inner cylinder; 13. Dispersing hole; 14. Pushing blade; 15. Attracting opening; 16. Insect-blocking blade; 17. Escape-preventing opening.

[0020] Example 1 is basically as shown in the appendix. Figure 1 , Figure 2 The diagram shows a pine wilt nematode control device, comprising a top cover 1, a trapping tube 3, and an insect collector 4. The insect collector 4 is threadedly connected to the bottom of the trapping tube 3, and the top cover 1 is threadedly connected to the top of the trapping tube 3. A solar panel 5 is mounted on the outer wall of the top cover 1, and a battery electrically connected to the solar panel 5 is located inside the top cover 1. A partition 6 is located inside the top cover 1, and a rainproof eave 2 extending beyond the outer wall of the trapping tube 3 is located on the outer wall of the top cover 1. The trapping tube 3 contains an inner tube 12 for holding attractants. An opening for placing the attractants is located on the side wall near the upper end of the inner tube 12, and a sealing door 11 is provided at the opening. Several dispersing holes 13 are evenly distributed on the wall of the inner tube 12, with a hole diameter of 0.2–0.4 cm.

[0021] A rotating shaft 9 is fixedly connected to the top of the inner cylinder 12. The rotating shaft 9 is rotatably connected to the partition 6 via ball bearings. A gear ring 10 is connected to the rotating shaft 9, and the gear ring 10 meshes with a gear 8. The gear 8 is connected to a motor 7, which is located above the partition 6. The motor 7 is electrically connected to a battery, and a timer switch is provided between the motor 7 and the battery, for example, turning on once every 20 minutes for a continuous 2-minute period. The inner cylinder 12 is located inside the trapping cylinder 3 and the two are coaxial. The outer wall of the inner cylinder 12 is also provided with several pushing blades 14, which are arranged in multiple rows and columns on the outer wall of the inner cylinder 12. The edges of the pushing blades 14 are provided with comb teeth. When the pushing blades 14 overlap with the insect-blocking blades 16, the insect-blocking blades 16 slide between the teeth of the comb teeth.

[0022] The trapping tube 3 has several attraction openings 15 arranged in multiple rows on the wall of the trapping tube 3. Inside each attraction opening 15, multiple insect-blocking blades 16 with elastic deformation characteristics are arranged in a ring. Each insect-blocking blade 16 is equilateral triangular in shape, with its wider end connected to the attraction opening 15. The insect-blocking blades 16 are made of cut rubber. The ends of the multiple insect-blocking blades 16 furthest from the attraction opening 15 are brought closer together to form an escape-prevention opening 17, the diameter of which is smaller than the diameter of the attraction opening 15.

[0023] When the motor 7 drives the gear 8 to rotate, and the inner cylinder 12 rotates through the gear 8, the extrusion blade 14 overlaps with the insect-blocking blade 16. The extrusion blade 14 squeezes and bends the insect-blocking blade 16. After the extrusion blade 14 and the insect-blocking blade 16 are completely intersected, the insect-blocking blade 16 recovers under its elasticity and forms the escape-proof opening 17 again.

[0024] The specific implementation process is as follows: The device is fixed in an outdoor location where the pine sawyer beetle frequently appears. The scent emitted by the attractant in the inner cylinder 12 overflows from the attraction port 15. Attracted pine sawyer beetles enter through the attraction port 15. After entering the attraction port 15, the space in front of the beetle becomes increasingly narrow, making it difficult for it to turn around and fly out. The beetle gets stuck at the escape prevention port 17. The timer switch is turned on once every 20 minutes. During this time, the motor 7 drives the gear 8 to rotate the inner cylinder 12. When the pushing blade 14 overlaps with the insect-blocking blade 16, the pushing blade 14 squeezes and bends the insect-blocking blade 16. At this time, the pine sawyer beetle stuck at the escape prevention port 17 is pushed completely into the trapping cylinder 3 and falls into the insect collector 4 below under the action of gravity. After 2 minutes of continuous power supply, the timer switch automatically turns off the power, and the motor 7 stops rotating to avoid wasting electricity.

[0025] After the pushing blade 14 and the insect-blocking blade 16 are completely intersected, the insect-blocking blade 16 returns to its original position under its elasticity and forms the escape-proof opening 17 again. The pine beetle that wants to fly out of the escape-proof opening 17 can fly out because the escape-proof opening 17 is relatively narrow. Secondly, due to the interference of the pushing blade 14 during the rotation of the inner cylinder 12, the pine beetle cannot distinguish the direction and has difficulty finding the escape-proof opening 17. Therefore, even the smaller pine beetle will become tired due to the repeated interference of the rotating pushing blade 14 and eventually become exhausted and stay in the insect collector 4.

[0026] Example 2 differs from Example 1 in that the gear ring 10 and gear 8 are replaced with pulleys, and a belt is tensioned between the pulleys.

[0027] The above scheme can also include a wind power generation structure outside the top cover 1, which can be a combination of wind power generation or solar energy storage, or either alone.
