Description

Technical Field

[0001] The invention relates to the technical field of plant sampling, in particular to a device for punching and sampling diseased plants of crop wilt in the field. Background Art

[0002] Crop wilt is a common plant disease caused by a variety of pathogens, including fungi, bacteria and viruses. It mainly affects the root system and vascular bundle of plants, causing the plants to gradually decline or even die. In field crops, wilt disease usually manifests as yellowing, shrinking and drying of plant leaves, damage to the root system, and inhibition of plant growth, which in turn affects the yield and quality of crops. This disease poses a serious threat to agricultural production, especially in poor planting environments or improper management, which can easily lead to large-scale crop losses. Therefore, timely and effective monitoring and treatment of wilt disease are important measures to ensure crop health and increase agricultural production.

[0003] In the existing technology, the simplest method of sampling diseased plants of crop wilt in the field is usually to use a manual punch or an electric drill to directly punch holes in the diseased plants. This method is easy to operate, simple in structure, and easy to carry. However, its disadvantage is that it can easily lead to excessive or unnecessary sample collection, which may inadvertently damage healthy plants or collect non-target tissues, affecting the accuracy and representativeness of the research. In addition, the randomness and irregularity of manual operations may lead to sample contamination, increasing the complexity of sample processing and analysis. Summary of the invention

[0030] Reference Figure 1-3An embodiment of the present invention is a device for sampling crop wilt diseased plants in the field by drilling holes, comprising a first threaded sleeve 1, wherein the inner wall of the first threaded sleeve 1 is threadedly connected to a first threaded rod 4, a fixed disk 3 is fixedly connected to the top of the outer ring of the first threaded sleeve 1, a first rotating disk 8 is fixedly connected to the top of the first threaded rod 4, and the first rotating disk 8 can be driven to rotate by rotating the first rotating disk 8, a fixing ring 9 is passed through and fixedly connected to the top of the first rotating disk 8, and the bottom of the fixing ring 9 is passed through and fixedly connected to the first threaded rod 4, and a screw 14 is passed through and slidably connected to the top of the first rotating disk 8, and the first rotating disk 8 and the fixed disk 3 can be fixedly connected by the screw 14. The fixing ring 9 is fixed to prevent the first threaded rod 4 from rotating. The top of the fixing ring 9 passes through and is slidably connected with a second threaded sleeve 10. The outer ring of the second threaded sleeve 10 is fixedly connected with a fixing block 11. The second threaded sleeve 10 can be driven to rise by lifting the fixing block 11. The top of the fixing block 11 is threadedly connected with a bolt 12, and the fixing of the fixing block 11 can be released by rotating the bolt 12. The inner wall of the second threaded sleeve 10 is threadedly connected with a second threaded rod 5, and the second threaded rod 5 can be moved up and down in the second threaded sleeve 10 by rotating it. The top of the outer ring of the second threaded rod 5 is fixedly connected with a second turntable 13, and the bottom of the outer ring of the second threaded rod 5 is fixedly connected with a spiral blade 6.

[0031] A drill bit 7 is fixedly connected to the bottom of the second threaded rod 5, and the drill bit 7 can easily penetrate the tissue of the plant. The outer ring of the drill bit 7 penetrates and is slidably connected to the second threaded rod 5. A handle 2 is fixedly connected to the middle of the outer ring of the first threaded sleeve 1, and the first threaded sleeve 1 can be held by the handle 2 to prevent the first threaded sleeve 1 from rotating. A threaded hole 17 is opened on the top of the fixed disk 3, and the threaded hole 17 is convenient for the screw 14 to fix the first rotating disk 8. The inner wall of the threaded hole 17 is threadedly connected to the screw 14. The front end of the first threaded rod 4 penetrates and is fixedly connected with an observation window 15. The observation window 15 is convenient for observing the internal samples. The front end of the observation window 15 penetrates and is fixedly connected with a scale 16, and the number of samples can be judged by the scale 16.

[0032] Working principle: first, hold the first threaded sleeve 1 through the handle 2, and then rotate the first turntable 8. The first threaded rod 4 rotates in the first threaded sleeve 1, so that the first threaded rod 4 drives the second threaded rod 5 to move downward at the same time. During the rotation and movement, the drill bit 7 penetrates the tissue of the plant, so that the collection area can be reached. The screw 14 is fixed to the first turntable 8 through the threaded hole 17 to prevent the first turntable 8 from rotating, so as to rotate the second turntable 13, so that the second threaded rod 5 rotates in the second threaded sleeve 10, so that the second threaded rod 5 can move up and down. The up and down movement of the second threaded rod 5 enables the spiral blade 6 to collect the sample and enter the first threaded rod 4. Finally, by rotating the bolt 12, the bolt 12 is released to fix the fixing block 11, and then the fixing block 11 is picked up. The fixing block 11 drives the second threaded sleeve 10 to rise. Because the second threaded sleeve 10 and the second threaded rod 5 are threadedly connected, the second threaded sleeve 10 drives the second threaded rod 5 to move upward at the same time, so that the collected sample can be extracted, which is convenient for observing the sample and disassembling and cleaning the device.
