Technical Field

[0001] The utility model relates to the technical field of solar panel installation, in particular to a tobacco black shank disease sample collection device. Background Art

[0002] More and more people are starting to grow tobacco, but every year there is a kind of tobacco black shank disease, also known as tobacco black root or black stem madness. It is a soil-borne fungal disease that occurs on tobacco and is caused by infection by tobacco blight. It causes tobacco to become diseased and leads to a decrease in yield.

[0003] Existing sampling equipment uses a blade to scrape out tobacco rhizome samples and then stores them in a storage bag. This process can easily cause sample contamination, resulting in inaccurate experimental data. Utility Model Content

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A tobacco black shank disease sample collection device includes a mounting frame, wherein the bottom inner wall of the mounting frame is fixedly connected to two first contraction springs, the top ends of the two first contraction springs are fixedly connected to a limiting block, the top of the limiting block is fixedly plugged with a sliding tube, the circumferential outer wall of the sliding tube is slidably sleeved with a guide tube, the top end of the guide tube is fixed to the bottom of the mounting frame, the bottom end of the sliding tube is rotatably connected to two flip shafts, the outer wall of the flip shaft is fixedly connected to a blade, one side of the blade is fixedly connected to a second contraction spring, the top end of the second contraction spring is fixedly connected to the bottom end of the sliding tube, the circumferential outer wall of the guide tube is provided with a threaded groove, the circumferential outer wall of the guide tube is sleeved with a protective sleeve through the threaded groove, and the bottom end of the protective sleeve is threadedly plugged with a collection tube.

[0007] Furthermore, handles are fixedly connected to the outer walls at both ends of the mounting frame.

[0008] Furthermore, an anti-slip groove is provided on the outer wall of the handle.

[0009] Furthermore, the top end of the sliding tube passes through the top end of the mounting frame and is fixedly connected to a handle.

[0010] The beneficial effects of the utility model are:

[0011] 1. By pulling the sliding tube to move in the guide tube, the blade is driven to move upward, and then the blade is rotated inward under the squeezing of the guide tube, so that the sample can be collected conveniently and quickly.

[0012] 2. By screwing the collection tube to the bottom end of the protective sleeve, the sliding tube is reset under the action of the first contraction spring, thereby releasing the blade. Then, the sample falls into the collection tube for collection, thereby facilitating sample collection and avoiding sample contamination. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Reference Figure 1-Figure 3 A tobacco black shank disease sample collection device includes a mounting frame 1, two first contraction springs 3 are welded to the inner wall of the bottom of the mounting frame 1, and the tops of the two first contraction springs 3 are welded to a limit block 4. A sliding tube 7 is fixedly inserted on the top of the limit block 4, and a guide tube 5 is slidably sleeved on the circumferential outer wall of the sliding tube 7. The top of the guide tube 5 is fixed to the bottom of the mounting frame 1, and the bottom end of the sliding tube 7 is rotatably connected to two flip shafts 10. The outer wall of the flip shaft 10 is welded with a blade 9. Pulling the sliding tube 7 to move in the guide tube 5 drives the blade 9 to move upward, and then squeezes the guide tube 5. Pressing down causes the blade 9 to rotate inward, thereby collecting the sample. A second contraction spring 301 is welded to one side of the blade 9. The top of the second contraction spring 301 is fixedly connected to the bottom end of the sliding tube 7. The circumferential outer wall of the guide tube 5 is provided with a threaded groove 6. The circumferential outer wall of the guide tube 5 is sleeved with a protective sleeve 11 through the threaded groove 6. The bottom end of the protective sleeve 11 is threadedly inserted with a collecting tube 12. The collecting tube 12 is screwed to the bottom end of the protective sleeve 11, and then the sliding tube 7 is reset under the action of the first contraction spring 3, thereby releasing the blade 9. Then, the sample falls into the collecting tube 12 for collection.

[0019] Handles 2 are welded to the outer walls of both ends of the mounting frame 1 to facilitate holding the sample collection device. The outer walls of the handles 2 are provided with anti-slip grooves, and the top of the sliding tube 7 passes through the top of the mounting frame 1 and is welded with a handle 8 to facilitate operation of the sliding tube 7.

[0020] The working principle of this embodiment is as follows: when in use, first, hold the handle 2 with one hand, then lift the handle 8 upward to drive the sliding tube 7 to move in the guide tube 5, thereby driving the blade 9 to move upward, and then the blade 9 rotates inward under the pressure of the guide tube 5 to collect the sample, then, block the hand lifting the handle 8 under the handle 8, and then use the hand holding the handle 2 to screw the collection tube 12 to the bottom end of the protective sleeve 11, then release the handle 8, and under the action of the first contraction spring 3, the sliding tube 7 is reset, thereby releasing the blade 9, and then the sample falls into the collection tube 12 for collection.

[0021] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
