[0002] The sampling device for potato virus detection is a tool specifically designed to collect potato plant samples. It usually consists of a sharp core drill and a sample cylinder. The core drill is a metal cylinder with a thin bottom and a wide top. When in use, the core drill is inserted into the plant tissue, and the connection part between the core drill and the plant is cut off with a knife. Then the core drill is taken out from the plant, shaken gently to release the sample, and finally the sample is poured into an appropriate container to complete the sampling operation. Since the potato plant tissue will undergo an oxidation reaction with the oxygen in the air after being damaged, it is necessary to perform a sampling cutting operation on the potato.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0031] Referring to Figures 1-4 , the present utility model provides a technical solution: a sampling device for potato virus detection, including a sampling cylinder 1 and a sampling cutting mechanism. A knife ring 2 is installed at the bottom of the sampling cylinder 1, and a force-applying plate 3 is installed at the top on the right side of the inner wall of the sampling cylinder 1. When the knife ring 2 is used in cooperation with the sampling cylinder 1, it can perform the cutting and separating work on the potato sample entering the rear side inside the knife ring 2, avoiding the situation that it is difficult to perform the cutting and separating work on the potato sample when the knife ring 2 and the sampling cylinder 1 are used. Therefore, the sampling cutting convenience of the knife ring 2 and the sampling cylinder 1 is improved.

[0032] Referring to Figures 1-4 , in a preferred embodiment, the sampling cutting mechanism includes a perforation 4. The perforation 4 is opened at the bottom on both sides inside the sampling cylinder 1. A steel wire 5 is movably connected inside the perforation 4. Docking grooves 6 are opened at the bottom on both sides of the sampling cylinder 1. Docking seats 7 located inside the docking grooves 6 are fixedly connected to the tops on both sides of the knife ring 2. Screw holes 8 are opened inside the docking seats 7 and the sampling cylinder 1. The inner side of the screw hole 8 is communicated with the outer side of the perforation 4. A bolt 9 is threadedly connected inside the screw hole 8. A lifting and measuring mechanism is fixedly connected to the top on the left side of the inner wall of the sampling cylinder 1. Hold the sampling cylinder 1 and drive the knife ring 2 to pierce into the sampled potato. At this time, the steel wire 5 moves into the potato following the knife ring 2 and performs the cutting and separating work on the potato entering the knife ring 2 from the middle. When it is necessary to perform the cutting operation on the potato after the potato sampling is completed, hold the sampling cylinder 1 and rotate the steel wire 5 through the knife ring 2 to prompt the steel wire 5 to rotate and perform the cutting and separating work on the connection between the potato entering the sampling cylinder 1 and the sampled potato. The lifting and measuring mechanism includes a lifting frame 10, a lifting rod 11, and a scale bar 12. The lifting frame 10 is fixedly connected to the top on the left side of the inner wall of the sampling cylinder 1. The lifting rod 11 is movably connected inside the lifting frame 10. The scale bar 12 is inlaid and connected to the outer side of the lifting rod 11. When the steel wire 5 is used in cooperation with the knife ring 2, before the steel wire 5 is used in cooperation with the knife ring 2 to cut the potato sample, it can perform the measurement work on the potato sample, so as to perform the measurement work on the cutting height of the sample according to the actual sampling requirements during use, avoiding the situation that it is difficult to perform the cutting measurement when the sampling cylinder 1 is used. Therefore, the cutting measurement convenience of the sampling cylinder 1 is improved.

[0033] Referring to Figures 3-4, in a preferred embodiment, a push plate 13 is movably connected to the bottom of the left side inside the sampling cylinder 1, and the left side of the top of the push plate 13 is fixedly connected to the bottom of the lifting rod 11. When the measuring rod is used in cooperation with the sampling cylinder 1, the contact area between the lifting rod 11 and the potato sample inside the sampling cylinder 1 can be increased, and it can prepare for pushing the cut potato sample out of the sampling cylinder 1 later, avoiding the situation that it is difficult for the lifting rod 11 to fully contact and rise with the potato sample during use. Therefore, the rising measurement effect of the lifting rod 11 is improved. Reinforcing cylinders 14 are fixedly connected to both sides of the left side of the inner wall of the sampling cylinder 1 and are located outside the lifting frame 10. A reinforcing frame 15 is movably connected inside the reinforcing cylinder 14, and the bottom of the reinforcing frame 15 is connected to the top of the push plate 13. When the push plate 13 is used in cooperation with the lifting rod 11, lifting and strengthening work can be carried out between the push plate 13 and the sampling cylinder 1, avoiding the situation that the push plate 13 is deformed under force during use. Therefore, the use stability of the push plate 13 is improved.

[0034] Refer to Figures 3-4 , in a preferred embodiment, a fitting groove 16 is formed at the bottom of the reinforcing frame 15, and the top of the inner wall of the fitting groove 16 is fixedly connected to the top of the push plate 13. When the reinforcing frame 15 is used in cooperation with the push plate 13, sufficient space for connecting and fixing between the reinforcing frame 15 and the push plate 13 can be provided, avoiding the situation that the connection between the fixing frame and the push plate 13 is insufficient during use. Therefore, the connection effect between the fixing frame and the push plate 13 is improved. A magnetic sheet 17 is inlaid and connected to the top of the right side of the reinforcing frame 15, and the right side of the magnetic sheet 17 is magnetically connected to the left side of the inner wall of the reinforcing cylinder 14. When the fixing frame is used in cooperation with the push plate 13, magnetic attraction positioning work can be carried out on the push plate 13 and the lifting rod 11 after rising through the fixing frame, avoiding the situation that it is difficult to position the push plate 13 and the lifting rod 11 during use. Therefore, the positioning convenience of the push plate 13 and the lifting rod 11 is improved.

[0035] Refer to Figures 3-4, in a preferred embodiment, a magnetic attraction sheet 18 is embedded and connected to the right side of the inner wall of the reinforcement cylinder 14, and the left side of the magnetic attraction sheet 18 is magnetically connected to the right side of the magnetic sheet 17. When the magnetic sheet 17 is used in cooperation with the push plate 13, a magnetic attraction positioning medium can be provided for the magnetic sheet 17, avoiding the situation that it is difficult to effectively magnetically position the push plate 13 and the lifting rod 11 through the reinforcement frame 15 when the magnetic sheet 17 is used. Therefore, the magnetic attraction positioning effect of the magnetic sheet 17 is improved. The left side of the top of the sampling cylinder 1 is movably connected with a pressing plate 19, and the bottom of the pressing plate 19 is fixedly connected to the top of the reinforcement frame 15 and the lifting rod 11 respectively. After the reinforcement frame 15 and the lifting rod 11 are used, a medium for synchronously moving the lifting rod 11 and the reinforcement frame 15 downward for reset can be provided for the user, and the reinforcement frame 15 and the lifting rod 11 during the downward movement can be limited, avoiding the situation that it is difficult to press and reset the lifting rod 11 and the reinforcement frame 15 when they are used. Therefore, the convenience of downward reset of the reinforcement frame 15 and the lifting rod 11 is improved.

[0036] Specifically, the working process or principle of a sampling device for potato virus detection is as follows: When in use, first hold the steel wire 5 by hand and pass it through the perforation 4 to penetrate the sampling cylinder 1, and make the steel wire 5 located inside the sampling cylinder 1 after passing through the inside of the sampling cylinder 1 to prepare for cutting the potato later. Then, hold the knife ring 2 by hand and drive the docking seat 7 into the docking groove 6 to perform a docking operation between the knife ring 2 and the sampling cylinder 1. And turn the bolt 9 with a screwdriver to pass through the docking seat 7 and the sampling cylinder 1 through the screw hole 8 into the perforation 4 to connect and fix the docking seat 7, the knife ring 2 and the sampling cylinder 1, and perform the work of tightly fixing the steel wire 5 inside the perforation 4. Note that when tightly fixing the steel wire 5 with the bolt 9, after turning the bolt 9 to tightly fix one end of the steel wire 5, pull the other end of the steel wire 5 so that the steel wire 5 located inside the sampling cylinder 1 is in a tightened state, and then turn the bolt 9 on the other side to perform the operation of tightly positioning the steel wire 5 to ensure the tightness of the steel wire 5 after tight positioning. Subsequently, hold the sampling cylinder 1 by hand and drive the knife ring 2 to pierce into the sampled potato. At this time, the steel wire 5 moves into the potato following the knife ring 2 and performs the work of cutting and separating the potato that enters the knife ring 2 from the middle. During this process, since the bottom of the push plate 13 is at the same horizontal line as the position of the steel wire 5, as the potato enters, the push plate 13 exerts an upward thrust on the lifting rod 11, prompting the lifting rod 11 to drive the scale bar 12 to rise to measure the height of the potato that enters the sampling cylinder 1 for controlling the sampling height of the potato during use. At this time, the reinforcement frame 15 moves inside the reinforcement cylinder 14 following the push plate 13 to reinforce the push plate 13 during the rising process. At the same time, through the cooperation of the magnetic sheet 17 and the magnetic attraction sheet 18, the lifting rod 11 and the push plate 13 after rising are magnetically positioned by the reinforcement frame 15. When it is necessary to perform a cutting operation on the potato after the potato sampling is completed, hold the sampling cylinder 1 by hand and rotate the steel wire 5 through the knife ring 2, prompting the steel wire 5 to rotate to cut and separate the connection between the potato that enters the sampling cylinder 1 and the sampled potato. Then, hold the sampling cylinder 1 by hand and drive the potato sample to move out of the potato, and hold a sample bag or sample box and sleeve it on the surface of the sampling cylinder 1. Then, hold the pressing plate 19 by hand and exert a downward thrust on the lifting rod 11 and the reinforcement frame 15, prompting the push plate 13 to push the potato sample inside the sampling cylinder 1 to move downward and separate from the sampling cylinder 1 and enter the sample bag or sample box. At the same time, the pressing plate 19 performs the work of limiting the downward movement of the lifting rod 11 and the reinforcement frame 15 during the downward movement. When the bottom of the pressing plate 19 contacts the top of the reinforcement cylinder 14 and the lifting frame 10, it means that the lifting rod 11 and the reinforcement frame 15 are reset.
