[0002] With the expansion of corn planting scale and the increase of continuous cropping years, the occurrence of corn stem rot has become increasingly serious, and has become one of the main bottlenecks restricting the sustainable development of the corn industry in Lvliang City. Corn stem rot is a soil-borne disease caused by a variety of pathogenic bacteria, which mainly damages the base of corn stems, leading to plant lodging, yield reduction or even total crop failure. This disease has the characteristics of rapid onset, wide spread, and difficult control, and once it occurs, it often causes serious economic losses.

[0003] There is an existing corn stem sampler with the authorized publication number CN206177613U. In the process of identifying corn that has suffered from stem base rot, the identification results are often affected by human hands contacting the corn stem samples, and at the same time, there is also the problem of inaccurate collection positions of corn stem segments. In this product, the left clamping piece and the right clamping piece are arranged vertically side by side, the left clamping piece is fixedly connected integrally with the left handle through the left connecting rod, the right clamping piece is fixedly connected integrally with the right handle through the right connecting rod, and the left connecting rod and the right connecting rod are hinged through a rotating shaft; the left cutting knife and the right cutting knife are both located between the left clamping piece and the right clamping piece, the left cutting knife and the right cutting knife are both "C"-shaped knife bodies, and when the left cutting knife and the right cutting knife are in contact with each other, a stem block storage cavity is formed between the left cutting knife and the right cutting knife, and the measuring ruler assembly is arranged on the outer wall of the left clamping piece or the right clamping piece. The utility model is used as a sampler for diseased parts of corn stem base rot.

[0004] In view of the above related technologies, the existing sampler has the defect that pathogenic bacteria mostly invade from root wounds or epidermis, which initially causes fibrous roots and lateral roots to turn brown and rot, losing the function of absorbing water and nutrients; as the disease progresses, the taproot will also rot gradually, resulting in a "rotten root" phenomenon. Existing samplers usually sample the rotten part through multiple shearing operations, but during the shearing process, the rotten rhizome is easy to break, resulting in incomplete sampling. Therefore, the utility model provides a sampler for diseased parts of corn stem rot. Contents of the Utility Model

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.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] Example 1: Reference Figure 1-4The illustrated corn stalk rot sampler includes a pair of main handles 1, which are held by the operator to provide a stable force point for sampling and facilitate control of the overall movement of the sampler. A bidirectional cutting component is provided on the outer side of the main handles 1. This component is used to cut the corn stalk rot from different directions, improving the integrity and efficiency of the sampling. The bidirectional cutting component includes a fixing frame 21 fixedly connected to the outer side of the main handles 1. The fixing frame 21 serves to fix and support the movable handles 2, providing a stable foundation for the rotation of the movable handles 2. Both ends of the fixing frame 21 are rotatably connected to the movable handles 2 via pivots, allowing the movable handles 2 to rotate around the pivots. The main handle 1 is used to control the cutting action; a main shearing blade 3 is fixedly connected to the outside of the main handle 1. The main shearing blade 3 serves as the primary cutting component and is used for initial cutting of the corn stalk; a secondary shearing blade 4 is rotatably connected to the outside of the main shearing blade 3. The secondary shearing blade 4 works in conjunction with the main shearing blade 3 to achieve bidirectional cutting, ensuring that diseased samples are cut off smoothly; a sample collection component is set below the pair of main shearing blades 3. The sample collection component is used to receive and collect the cut diseased samples to prevent samples from falling and contaminating; the sample collection component includes a collection frame 7 set below the main shearing blades 3. The collection frame 7 is used to directly hold the cut diseased samples to prevent samples from scattering; the collection frame 7... A rubber band 8 is fixedly connected to the outside of the collection frame 7. The rubber band 8 is elastic and connects the cover plate 9 to the collection frame 7. One end of the rubber band 8 is fixedly connected to the cover plate 9, which is adapted to the collection frame 7. The cover plate 9 is used to close the collection frame 7 to prevent the sample from falling or being contaminated during the transfer process. A pair of upper magnetic plates 13 and lower magnetic plates 14 are respectively embedded in the top and bottom of the collection frame 7. A magnetic block 12 adapted to the upper magnetic plates 13 and lower magnetic plates 14 is fixedly connected to the outside of the cover plate 9. The upper magnetic plates 13 and lower magnetic plates 14 cooperate with the magnetic block 12 to fix the cover plate 9 in the open and closed states, improving the convenience of use. A positioning rod 10 is fixedly connected to the bottom of the fixing frame 21. A fixed insertion rod 11 is attached to the side. A slot adapted to the insertion rod 11 is provided on the inner side of the positioning rod 10. The positioning rod 10 and the insertion rod cooperate through the slot to realize the detachable connection between the collection frame 7 and the fixing frame 21, which facilitates the disassembly and cleaning of the collection frame 7 and the transfer of samples. Grooves 15 are provided on both sides of the insertion rod 11. A protrusion 17 is provided in the groove 15. The protrusion 17 is made of rubber. The inner wall of the slot is provided on both sides with a slot 16 adapted to the protrusion 17. The groove 15 provides installation space for the protrusion 17. The rubber protrusion 17 is elastic. It cooperates with the slot 16 to realize the clamping and fixing of the insertion rod 11 and the positioning rod 10, which improves the connection stability and facilitates disassembly.

[0019] Example 2: Reference Figure 1-4Based on the same concept as in Embodiment 1 above, this embodiment also proposes that a connecting rod 20 is fixedly connected to the outer side of the secondary shearing blade 4. The connecting rod 20 is used to transmit the motion force of the secondary shearing blade 4. An L-shaped movable rod 19 is movably connected to its outer side. The L-shaped movable rod 19 can be rotated to adjust its position to adapt to the transmission requirements. A slot 18 adapted to the L-shaped movable rod 19 is opened on the outer side of the movable handle 2. The slot 18 provides the L-shaped movable rod 19 with a space for movement and limits its offset trajectory. Springs 6 are fixedly connected between the two sides of the main handle 1 and a pair of movable handles 2. The springs 6 can generate elastic restoring force after the movable handles 2 are pressed to ensure that the handles return to their position quickly. A fixing rod 5 is fixedly connected to the outer side of the movable handle 2. The fixing rod 5 is used to position the installation position of the springs 6 and prevent the springs 6 from shifting. The springs 6 are sleeved on the outer side of the fixing rod 5.

[0020] The working principle of this utility model is as follows: The corn root is placed between a pair of main shearing blades 3 and secondary shearing blades 4. By holding and squeezing a pair of movable handles 2, the movable handles 2 drive the secondary shearing blades 4 to move via the L-shaped movable rod 19. In conjunction with the main shearing blades 3, the secondary shearing blades 4 and rotten parts of the corn root are cut simultaneously. The cut parts fall into the collection frame 7. Pushing the insertion rod 11 causes the protrusion 17 to deform under pressure, which causes the collection frame 7 to detach from the device. Dragging the cover plate 9 flips the frame over, causing the magnetic block 12 to detach from the attraction of the lower magnetic plate 14 until the cover plate 9 covers the outside of the collection frame 7. The magnetic block 12 then attracts the upper magnetic plate 13, thus protecting the sample.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
