Abstract
Description
Technical Field
[0001] This utility model relates to the field of insect collection equipment technology, specifically to a pine wood nematode collection device. Background Technology
[0002] Pine wilt disease, caused by the pine wood nematode, is a devastating forest disease often referred to as "the cancer of pine trees," posing a serious threat to coniferous forest ecosystems worldwide. The pine wood nematode is primarily transmitted by vector insects (such as the pine sawyer beetle). After infecting pine trees, it rapidly damages their vascular tissue, causing the trees to wither and die within a short period. Collecting pine wood nematode samples and then identifying, counting, and analyzing the pathogenicity of the nematodes provides crucial information for early disease warning, epidemiological studies, and the development of control strategies.
[0003] When existing devices are installed and fixed in the external environment, the installation position and angle vary due to different installation environments. The installation and fixing structure of existing devices is relatively simple and difficult to adapt to fixing carriers of different specifications (such as tree trunks of different thicknesses or monitoring poles). Furthermore, it is not convenient to adjust the fixing direction to adapt to complex field environments, thereby reducing the applicability of the device. Utility Model Content
[0004] This utility model addresses the technical problems existing in the prior art by providing a pine wood nematode collection device. It solves the problems that the existing devices have a relatively simple installation and fixing structure, making it difficult to adapt to fixing carriers of different specifications, and it is not convenient to adjust the fixing direction to adapt to complex field environments, thereby reducing the applicability of the device.
[0005] To achieve the above objectives, this utility model provides a pine wood nematode collection device, including a base, a collection mechanism fixedly connected to the top of the base, and a fixing component provided at the bottom of the base. The fixing component includes two arc-shaped connecting plates, the distance between which can be adjusted by relative or opposite movements of the two arc-shaped connecting plates, enabling the stable clamping of connectors of different specifications between the two arc-shaped connecting plates. An adjustment component is provided at one end of the fixing component, and the angle of the fixing component is adjusted by rotating the adjustment component to drive the rotation of one end of the fixing component, thus satisfying the connection requirements of the fixing component with connectors in different directions.
[0006] The beneficial effects of this utility model are:
[0007] 1. When dealing with connecting carriers of different specifications, the distance between the two arc-shaped connecting plates can be flexibly adjusted to clamp and fix the connecting carriers of different specifications, so that the device can be adapted to connecting parts of different diameters and expand the applicable scenarios of the device.
[0008] 2. For connection carriers in different directions, the connection angle of the fixed component can be adjusted by adjusting the component, so that the angle of the fixed component can be freely adjusted. The installation direction of the device can be adjusted in a timely manner. It is suitable for connection parts with different angles and at the same time, it can effectively ensure that the insect-attracting module in the insect collection mechanism is always facing the optimal monitoring direction (such as a well-ventilated or well-lit area), thereby improving the insect collection efficiency.
[0009] Based on the above technical solution, the present invention can be further improved as follows.
[0010] Preferably, an arc-shaped clamping plate is provided on one side of the arc-shaped connecting plate, and a number of protrusions are fixedly connected to one side of the arc-shaped clamping plate.
[0011] The beneficial effects of adopting the above-mentioned further solutions are that they increase the contact area, improve the stability of the foundation, increase the friction of the clamping surface, prevent the device from sliding due to external forces such as wind and vibration, ensure that it is firmly fixed, and reduce interference from the field environment.
[0012] Preferably, a flexible connector is fixedly connected between the arc-shaped connecting plate and the arc-shaped clamping plate. The flexible connector is provided with a plurality of sleeves and sliding rods. One end of the sleeve is fixedly connected to one side of the arc-shaped connecting plate, and one end of the sliding rod is fixedly connected to the other side of the arc-shaped clamping plate. The sliding rod slides inside the sleeve. One end of the sliding rod is fixedly connected to a limiting plate, and one end of the sleeve is fixedly connected to a retaining ring. The limiting plate slides inside the sleeve.
[0013] The beneficial effect of adopting the above-mentioned further solution is that it has a certain deformation capability, can adapt to the slight unevenness of the carrier surface, achieve "adaptive bonding", avoid carrier damage or clamping failure caused by excessive local stress, and further optimize the contact tightness.
[0014] Preferably, a first bolt is slidably connected to one end of one of the arc-shaped connecting plates, and the outer side of the first bolt is threadedly connected to one end of the other arc-shaped connecting plate.
[0015] The advantages of adopting the above-mentioned further solution are that the distance between the two plates can be precisely adjusted by rotating the first bolt. The operation is simple and efficient, and it is convenient for quick installation and debugging in the field. In addition, the threaded connection provides a stable locking force to ensure that the distance is fixed after adjustment and to avoid loosening of the clamp.
[0016] Preferably, the adjustment assembly includes a cross rod, one arc-shaped connecting plate with its other end fixedly connected to the cross rod, and the other arc-shaped connecting plate sliding on the outside of the cross rod. Rotating components are symmetrically fixedly connected to both ends of the cross rod. The rotating components are rotatably connected to the interior of the vertical plates on the front and rear sides of one end of the base. The interior of the disc at one end of the rotating component has several through holes arranged in a ring shape. A second bolt is slidably connected inside the uppermost through hole. The rod of the second bolt is threadedly connected to a threaded hole in the vertical plate at one end of the base.
[0017] The beneficial effects of adopting the above-mentioned further solution are that it achieves precise fixation of the device after angle adjustment, avoids loosening of the angle due to external force, realizes multi-angle positioning, ensures that the device is stably maintained at the preset angle, and avoids angle deviation from affecting the insect-attracting effect.
[0018] Preferably, the other end of the base is provided with a sliding groove, and a third bolt is slidably connected to one end of the two arc-shaped connecting plates. The third bolt can slide inside the sliding groove, and a nut is threadedly connected to the outside of the third bolt.
[0019] The beneficial effect of adopting the above-mentioned further solution is that when the fixing component supports the device, the other end is connected to the base through a third bolt, thereby improving the stability of the fixing component and the base support.
[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0021] By moving the two arc-shaped connecting plates in the fixed component relative to or away from each other, the clamping distance can be flexibly adjusted to adapt to connectors of different diameters (such as tree trunks and supports), expanding the applicable scenarios of the device. Furthermore, by adjusting the fixed component to drive the rotation of the fixed component, the angle can be freely adjusted, allowing the installation direction of the device to be adjusted. This makes it suitable for connectors with different directional angles, effectively ensuring that the insect-attracting module in the insect-collecting mechanism always faces the optimal monitoring direction (such as well-ventilated and well-lit areas), thus improving insect-collecting efficiency.

[0035] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0036] Please see Figures 1-7As shown, this embodiment provides a pine wood nematode collection device, including a base 1. A collection mechanism 2 is fixedly connected to the top of the base 1. Considering that existing devices are installed and fixed in different environments, resulting in different installation positions and angles, the existing installation and fixing structures are relatively simple and difficult to adapt to different specifications of fixing carriers (such as tree trunks of different thicknesses or monitoring poles), and it is not convenient to adjust the fixing direction to adapt to complex field environments, thus reducing the applicability of the device. Therefore, a fixing component 3 is provided at the bottom of the base 1. The fixing component 3 includes two arc-shaped connecting plates 31. The distance between the two arc-shaped connecting plates 31 can be adjusted by relative or opposite movements, which can stably clamp connecting parts of different specifications between the two arc-shaped connecting plates 31. An adjustment component 4 is provided at one end of the fixing component 3. By rotating the adjustment component 4, the angle of the fixing component 3 can be adjusted to meet the connection of the fixing component 3 with connecting parts in different directions, increasing the adaptability of the installation position of the collection mechanism 2.
[0037] In summary, the improvements in this embodiment are as follows:
[0038] By moving the two arc-shaped connecting plates 31 in the fixed component 3 relative to or opposite to each other, the clamping distance can be flexibly adjusted to adapt to connectors of different diameters (such as tree trunks and supports), thus expanding the applicable scenarios of the device. Figures 5-7 As shown, by adjusting component 4 to drive fixed component 3 to rotate, the angle can be freely adjusted, which allows the installation direction of the device to be adjusted. It is suitable for connectors with different directions and angles, effectively ensuring that the insect-attracting module in insect-collecting mechanism 2 can always face the optimal monitoring direction (such as a well-ventilated or well-lit area), thus improving insect-collecting efficiency.
[0039] Specifically,
[0040] To prevent the clamping structure from slipping during use, especially on wet or rough surfaces (such as bark) where the stability is poor and the device may shift or fall off, an arc-shaped clamping plate 32 is provided on one side of the arc-shaped connecting plate 31, and several protrusions 33 are fixedly connected to one side of the arc-shaped clamping plate 32.
[0041] The curved clamping plate 32 fits the curved surface of the cylindrical carrier (such as a tree trunk), increasing the contact area and improving the stability of the foundation. The protrusion 33 increases the friction of the clamping surface, preventing the device from sliding due to external forces such as wind and vibration, ensuring a firm fixation and reducing interference from the field environment.
[0042] Considering that rigid clamping structures are prone to uneven force when in contact with irregular surfaces (such as bark protrusions or cracks), which may lead to loosening of the clamping or damage to the carrier, and cannot buffer external impact, a flexible connector 34 is fixedly connected between the arc-shaped connecting plate 31 and the arc-shaped clamping plate 32. Several sleeves 35 and sliding rods 36 are respectively provided inside the flexible connector 34. One end of the sleeve 35 is fixedly connected to one side of the arc-shaped connecting plate 31, and one end of the sliding rod 36 is fixedly connected to the other side of the arc-shaped clamping plate 32. The sliding rod 36 slides inside the sleeve 35.
[0043] The flexible connector 34 is made of elastic material and has a certain deformation capacity. It can adapt to the slight unevenness of the carrier surface and achieve "self-adaptive fitting". It avoids carrier damage or clamping failure caused by excessive local stress. The sliding fit between the sleeve 35 and the slide bar 36 allows the arc-shaped clamping plate 32 to be finely adjusted with the surface shape of the carrier, further optimizing the contact tightness, while enhancing the structural buffering capacity and extending the service life of the device.
[0044] Considering that the slide bar 36 is prone to detach from the track due to excessive stretching or contraction when sliding inside the sleeve 35, resulting in structural failure and affecting clamping stability, a limiting plate 37 is fixedly connected to one end of the slide bar 36, and a retaining ring 38 is fixedly connected to one end of the inner side of the sleeve 35. The limiting plate 37 slides inside the sleeve 35.
[0045] The limiting plate 37 and the retaining ring 38 form a mechanical limit, restricting the maximum sliding distance of the slide rod 36, preventing the slide rod 36 from falling out of the sleeve 35, ensuring that the extension and retraction of the flexible connector 34 are always within a safe range, and guaranteeing structural stability and service life.
[0046] To improve ease of operation and enable the device to quickly adapt to different specifications of carriers, a first bolt 39 is slidably connected to one end of an arc-shaped connecting plate 31, and the outer side of the first bolt 39 is threadedly connected to one end of the inner side of another arc-shaped connecting plate 31.
[0047] The bolt sliding connection in a single arc-shaped connecting plate 31 and the threaded connection in another arc-shaped connecting plate 31 allow for precise adjustment of the distance between the two plates by rotating the first bolt 39. This operation is simple and efficient, facilitating quick installation and debugging in the field. The threaded connection provides a stable locking force, ensuring that the distance is fixed after adjustment and preventing loosening of the clamp.
[0048] In order to achieve precise fixation after the device angle is adjusted and to avoid loosening of the angle due to external force, the adjustment component 4 includes a cross rod 41, an arc-shaped connecting plate 31 with the other end fixedly connected to the cross rod 41, and another arc-shaped connecting plate 31 sliding on the outside of the cross rod 41. Rotating parts 42 are symmetrically fixedly connected to both ends of the cross rod 41. The rotating parts 42 are rotatably connected to the interior of the vertical plates on the front and rear sides of one end of the base 1. The interior of the disc at one end of the rotating part 42 is provided with several through holes 43 in a ring shape. The uppermost through hole 43 is slidably connected to a second bolt 44. The rod part of the second bolt 44 is threadedly connected to the threaded hole in the vertical plate at one end of the base 1.
[0049] The cross rod 41 cooperates with the rotating component 42 to achieve 180° rotation adjustment of the fixing component 3 along the rotation direction of the cross rod 41, meeting the installation requirements of different directions (such as horizontal, inclined or vertical fixation). The combination of the annular through hole 43 and the second bolt 44 can be threaded to the threaded hole on the vertical plate of the base 1 after the angle is adjusted by passing the second bolt 44 through the through hole 43, locking the position of the rotating component 42, realizing multi-angle positioning (such as fixing in 15° / 30° increments), ensuring that the device is stably maintained at the preset angle, and avoiding angle deviation that affects the insect-attracting effect.
[0050] Considering that the fixing component 3 is located at the bottom of the base 1, when supporting the base 1, it is only connected to one end of the base 1 by the adjusting component 4. This can easily cause the device to become unbalanced due to the shift in the center of gravity, affecting the stability of the device. Therefore, if Figure 5 As shown, a sliding groove 11 is provided inside the other end of the base 1, and a third bolt 5 is slidably connected inside one end of the two arc-shaped connecting plates 31. The third bolt 5 can slide inside the sliding groove 11, and a nut 51 is threadedly connected to the outside of the third bolt 5.
[0051] The other end of the two arc-shaped connecting plates 31 is connected to the base 1 by the third bolt 5. When the distance between the two arc-shaped connecting plates 31 is adjusted, the two third bolts 5 can slide inside the slide groove 11 and adjust their positions according to the arc-shaped connecting plates 31, increasing the flexibility of the connection between the device structures. After adjustment, the nut 51 locks and fixes the position of the third bolt 5, further enhancing the overall stability.
[0052] In summary, the working principle of this solution is as follows:
[0053] This pine wilt nematode collection device achieves adaptable installation and stable fixation in different environments through the coordinated operation of the base 1, fixing component 3, and adjusting component 4. The insect collection mechanism 2 is fixed at the top of the base 1, the fixing component 3 connected at the bottom solves the installation adaptation problem, and the adjusting component 4 ensures flexible angle adjustment.
[0054] During installation, the mounting carrier is inserted between the two arc-shaped connecting plates 31 from one end. A first bolt 39 is then inserted into one end of one arc-shaped connecting plate 31, with its shaft threaded into the other arc-shaped connecting plate 31. The spacing is precisely adjusted by rotating the first bolt 39 until the two arc-shaped clamping plates 32 contact the carrier surface, accommodating carriers such as tree trunks and monitoring rods of different diameters. The arc-shaped clamping plates 32 conform to the curved surface of the carrier, increasing the contact area, and their surface protrusions 33 enhance friction, preventing the device from sliding. The flexible connector 34 between the arc-shaped connecting plates 31 and the arc-shaped clamping plates 32 is made of elastic material, working in conjunction with the sliding connection between the sleeve 35 and the sliding rod 36. This allows the arc-shaped clamping plates 32 to adaptively adjust to the unevenness of the carrier surface, preventing excessive local stress that could cause damage or loosening. The limiting plate 37 and the retaining ring 38 form a mechanical limit, preventing the sliding rod 36 from detaching from the sleeve 35 and ensuring structural stability.
[0055] The adjusting component 4, through the cooperation of the cross rod 41 and the rotating component 42, enables the fixed component 3 to rotate 180°. The annular through holes 43 on the discs at both ends of the rotating component 42, combined with the second bolt 44, allow for precise locking in 15° / 30° increments after angle adjustment. This ensures the insect collecting mechanism 2 always faces the optimal monitoring direction. Simultaneously, the connection angle of the fixed component 3 can be flexibly adjusted to accommodate connections and fixations between the fixed component 3 and carriers in different orientations. The overall structure is easy to operate, quickly adapts to complex field environments, and improves insect collecting efficiency.
