Description

Technical Field

[0001] This utility model relates to the technical field of forestry pest and disease monitoring equipment, specifically a pine wilt disease monitoring sampler. Background Technology

[0002] Pine wilt disease is a devastating disease of pine trees caused by the parasitic pine wilt nematode. It is characterized by rapid spread, high mortality, and great difficulty in control, and is often referred to as the "cancer" of pine trees. In the daily monitoring and outbreak investigation of pine wilt disease, trunk sampling is the core step in obtaining nematode samples and confirming the outbreak.

[0003] However, in practical applications, existing technologies for pine wilt disease sampling mainly employ two methods: drilling and chiseling. Drilling requires drilling holes in the trunk to extract core samples, causing significant damage to the trunk and increasing the risk of secondary disease invasion. Furthermore, the drilling depth and sampling location are difficult to control precisely, making it impossible to accurately obtain the target tissue from the affected area. Chiseling requires first chiseling a crevices at the affected area, then manually opening the crevices with tools while another person uses tweezers to extract the sample. This requires two people to work together, making field operations extremely inconvenient. Additionally, manually opened crevices are prone to springing back and closing, making it difficult to maintain the required opening width for sampling. The device is also prone to displacement, leading to difficult sampling operations, insufficient sample representativeness, and directly affecting the accuracy of monitoring results.

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.

[0026] Please see Figure 1-4 This utility model provides a technical solution: a pine wilt disease monitoring sampler, comprising:

[0027] The support base 1, the first waist-shaped component 6, the second waist-shaped component 7 and the third waist-shaped component 8 are provided. Each end of the support base 1 is hinged with a clamping arm 2 and a spreading arm 4, and the two spreading arms 4 are located between the two clamping arms 2. The inner wall of the clamping arm 2 is fixedly installed with a clamping sleeve 21, and the clamping sleeve 21 is a rubber material component. The first waist-shaped component 6, the second waist-shaped component 7 and the third waist-shaped component 8 are arranged sequentially from top to bottom. The end of the spreading arm 4 away from the support base 1 is a tapered end, so that the spreading arm 4 can penetrate into the sampling position.

[0028] A first hinge rod 3 is fixedly installed at one end of the clamping arm 2 corresponding to the position of the support seat 1. A third hinge rod 9 is hinged at the end of the first hinge rod 3 away from the position of the clamping arm 2. A movable part 10 is rotatably connected at the middle of the end of the third hinge rod 9 away from the position of the first hinge rod 3, and the movable part 10 is movably connected between the second waist-shaped part 7 and the third waist-shaped part 8.

[0029] A second hinge rod 5 is fixedly installed at one end of the support arm 4 corresponding to the position of the support seat 1. The second hinge rod 5 is rotatably connected to a movable column 11 at the middle part away from the position of the support arm 4, and the movable column 11 is located between the first waist-shaped piece 6 and the second waist-shaped piece 7.

[0030] Waist-shaped grooves 12 are respectively provided in the middle of the first waist-shaped member 6, the top and bottom of the second waist-shaped member 7, and the middle of the third waist-shaped member 8. The movable column 11 is movably connected to the inner wall of the waist-shaped groove 12 between the first waist-shaped member 6 and the second waist-shaped member 7, and the movable member 10 is movably connected to the inner wall of the waist-shaped groove 12 between the second waist-shaped member 7 and the third waist-shaped member 8.

[0031] One end of the first waist-shaped component 6, the second waist-shaped component 7, and the third waist-shaped component 8 is fixedly installed with a movable plate 13, which is movably connected to the top of the support base 1.

[0032] Tweezers 24 are movably provided on the top of the support base 1;

[0033] When the above structure is in use, the first waist-shaped member 6, the second waist-shaped member 7, and the third waist-shaped member 8 are moved respectively by the movable plate 13:

[0034] The waist groove 12 between the second waist-shaped component 7 and the third waist-shaped component 8 will drive the movable component 10 to move towards one end of the handwheel 22, and cause the movable component 10 to drive the third hinge rod 9 to hinge with the first hinge rod 3, thereby causing the clamping arm 2 to hinge with the support seat 1, and causing the two clamping arms 2 to gradually rotate relative to each other to stably clamp the tree.

[0035] The waist-shaped groove 12 between the first waist-shaped component 6 and the second waist-shaped component 7 will drive the movable column 11 to move towards one end of the handwheel 22, and cause the movable column 11 to drive the spreading arm 4 to hinge with the support seat 1 through the second hinge rod 5, thereby causing the two spreading arms 4 to move away from each other and gradually widen the gap in the tree. When the pine nematode is exposed, the action stops. Since the threaded tube 14 and the threaded rod 15 can be self-locking, the spreading arm 4 can maintain the widened state of the gap. At this time, the tweezers 24 can be taken out to remove the pine nematode from the gap, thus achieving the purpose of easy removal of pine nematodes by a single person while reducing damage to the tree trunk.

[0036] The width of the waist-shaped groove 12 is adapted to the diameter of the movable column 11 and the width of the movable part 10. The movable part 10 has a waist-shaped structure so that the movable part 10 can move linearly on the inner wall of the waist-shaped groove 12. A connector 19 is fixedly embedded in the middle of the end of the movable part 10 away from the third hinge rod 9. A buffer spring 20 is fixedly installed at the end of the connector 19 away from the movable part 10, and the buffer spring 20 is fixedly installed at one end of the movable plate 13.

[0037] When the above structure is in use, by setting the connector 19, the waist-shaped groove 12 and the buffer spring 20, the connector 19 can move on the inner wall of the waist-shaped groove 12 between the second waist-shaped part 7 and the third waist-shaped part 8, and the buffer spring 20 can buffer and adjust the movement of the third hinge rod 9, that is, the rotation range of the clamping arm 2 can achieve the purpose of buffer adjustment, thereby achieving the purpose of clamping trees of different sizes.

[0038] A threaded tube 14 is fixedly embedded in the middle of the movable plate 13. A threaded rod 15 is threadedly connected to the inner wall of the threaded tube 14. A fixing frame 16 is fixedly installed in the middle of the inner wall of the support base 1. The threaded rod 15 is rotatably connected to the top of the support base 1 and the fixing frame 16 through a bearing. The threaded rod 15 moves through and extends to one end of the support base 1. A handwheel 22 is fixedly installed at the end of the threaded rod 15 away from the support base 1. A storage sleeve 23 is fixedly installed on the top of the fixing frame 16. Tweezers 24 are movably inserted into the inner wall of the storage sleeve 23.

[0039] When the above structure is in use, the handwheel 22 is turned, which drives the threaded rod 15 to rotate, thereby connecting the threaded rod 15 to the fixed frame 16. The threaded tube 14 then drives the movable plate 13 to move toward one end of the handwheel 22. When the device needs to be restored, the handwheel 22 can be turned in the opposite direction.

[0040] A guide rod 18 is fixedly installed between the fixed frame 16 and the inner wall of the support base 1. A guide tube 17 is movably sleeved on the surface of the guide rod 18, and the guide tube 17 is fixedly embedded in the middle of the movable plate 13, so that the movement of the movable plate 13 is guided by the guide tube 17 in conjunction with the guide rod 18. By setting the guide tube 17 and the guide rod 18, the movement of the movable plate 13 can be guided.

[0041] Working principle: When in use, the initial state of this utility model is that the clamping arms 2 at both ends are separated from each other, while the two spreading arms 4 are close to each other and fit together. First, a gap is knocked open in the tree with pine wood nematodes, and then the conical end of the spreading arm 4 is inserted into the gap, so that the tree is located between the two clamping arms 2.

[0042] Then, turn the handwheel 22, causing it to rotate the threaded rod 15, thereby connecting the threaded rod 15 to the fixed frame 16. This causes the threaded tube 14 to move the movable plate 13 towards one end of the handwheel 22. The guide tube 17 and guide rod 18 guide the movement of the movable plate 13. When the movable plate 13 moves towards the handwheel 22, it will cause the first waist-shaped member 6, the second waist-shaped member 7, and the third waist-shaped member 8 to move respectively. When the first waist-shaped member 6, the second waist-shaped member 7, and the third waist-shaped member 8 move towards one end of the handwheel 22:

[0043] The waist groove 12 between the second waist-shaped component 7 and the third waist-shaped component 8 will drive the movable component 10 to move towards one end of the handwheel 22, and cause the movable component 10 to drive the third hinge rod 9 to hinge with the first hinge rod 3, thereby causing the clamping arm 2 to hinge with the support seat 1, and causing the two clamping arms 2 to gradually rotate relative to each other to stably clamp the tree.

[0044] The waist-shaped groove 12 between the first waist-shaped component 6 and the second waist-shaped component 7 will drive the movable column 11 to move towards one end of the handwheel 22, and cause the movable column 11 to drive the spreading arm 4 to hinge with the support seat 1 through the second hinge rod 5, thereby causing the two spreading arms 4 to move away from each other and gradually widen the gap in the tree. When the pine nematode is exposed, the action stops. Since the threaded tube 14 and the threaded rod 15 can be self-locking, the spreading arm 4 can maintain the widened state of the gap. At this time, the tweezers 24 can be taken out to remove the pine nematode from the gap, thus achieving the purpose of easy removal of pine nematodes by a single person while reducing damage to the tree trunk.

[0045] By setting the connector 19, the waist-shaped groove 12 and the buffer spring 20, the connector 19 can move on the inner wall of the waist-shaped groove 12 between the second waist-shaped part 7 and the third waist-shaped part 8, and the buffer spring 20 can buffer and adjust the movement of the third hinge rod 9, that is, the rotation range of the clamping arm 2 can achieve the purpose of buffer adjustment, thereby achieving the purpose of clamping trees of different sizes.

[0046] When the device needs to be restored, simply turn the handwheel 22 in the opposite direction.
