Description

Technical Field

[0001] The utility model relates to the technical field of sampling devices for portable vegetable pesticide residue detection, and more specifically, it relates to a sampling device for portable vegetable pesticide residue detection. Background Technique

[0002] In the existing vegetable pesticide residue detection technology, the sampling process often involves multiple steps, which are not only cumbersome but may also have some safety and efficiency problems.

[0003] First of all, the traditional sampling method usually requires using scissors to cut the vegetables and then manually putting them into the sampling bucket. This process is not only time-consuming, but also the vegetables are prone to fall during the operation, resulting in sample loss or contamination. In addition, multiple transfers of the sample container may cause sample contamination, affecting the accuracy of the detection results.

[0004] Secondly, for vegetables growing in higher positions, the sampling process becomes more complicated. The operator may need to use a ladder or other climbing tools to reach the vegetables at high places. This not only increases the difficulty of the operation, but also there are safety hazards during the climbing process. The unevenness of the soil may cause the ladder to be unstable, increasing the risk of the operator falling and causing safety accidents.

[0005] To solve these problems, some technologies have adopted scissors with extended grips to reduce the need for the operator to climb. However, the grips of these scissors are usually of fixed length or non-adjustable, which means they may not be suitable for the heights of all operators or different usage scenarios. This design limits the flexibility of the operator and may lead to inconvenient operation or low efficiency. Content of the Utility Model

[0037] In this embodiment, when the grip 25 needs to be replaced, rotate the corresponding splicing sleeve 10. The splicing sleeve 10 drives the toothed ring 11 connected on one side to rotate. Then the toothed ring 11 drives the gear 12 meshing with it to continue rotating. Then the gear 12 drives the lead screw 8 to rotate. Since the limiting sleeve 7 is movably connected to the lead screw 8 through a thread, the limiting sleeve 7 will slide along the lead screw 8.

Then release the grip 25 and the splicing sleeve 10. Then the push spring 21 pushes the push plate 22 to reset, causing the push plate 22 to push the splicing rod 15 to move. Then the side wall of the limiting groove 14 will press one end of the limiting plate 9, so as to ensure the quick and stable installation of the grip 25.

[0039] One end of the splicing rod 15 is connected with a connecting rod 26, and the other ends of a plurality of connecting rods 26 are respectively connected to the movable rod 24, the fixed rod 23, and the grip 25.

[0040] More specifically, when the device needs to be used, first replace the corresponding grip 25. Then hold the grip 25 connected to one end of the fixed rod 23 with one hand, and then hold the grip 25 connected to one end of the movable rod 24 with the other hand. Then align the flared opening 17 provided on one side of the sampling bucket 1 with the vegetable to be sampled, so that the vegetable to be sampled enters the sampling bucket 1 through the flared opening 17. Then keep the grip 25 connected to one end of the fixed rod 23 stationary, and then move the grip 25 connected to one end of the movable rod 24. Then the grip 25 will drive the movable rod 24 to rotate around the fixed shaft 5 through components such as the connecting rod 26. Then the movable rod 24 will drive the movable scissors 4 connected to the other end to move around the fixed shaft 5. Then the movable scissors 4 will cooperate with the fixed scissors 3 to cut and sample the vegetable to be sampled. Then the cut vegetable will fall into the sampling bin 2 connected to one side of the sampling bucket 1. Then put down the sampling bucket 1 and rotate the sampling bin 2. Since the sampling bin 2 is detachably installed on one side of the sampling bucket 1 through threads, then the sampling bin 2 will be removed from one side of the sampling bucket 1. Then take away the sampling bin 2 and the cut vegetable for testing. Then a new sampling bin 2 can be installed on one side of the sampling bucket 1 for re-sampling.

[0041] In summary, when the overall device is in use or operation: when it is necessary to replace the grip 25, rotate the corresponding splicing sleeve 10. The splicing sleeve 10 drives the toothed ring 11 connected to one side to rotate. Then the toothed ring 11 drives the gear 12 meshed with it to continue rotating. Then the gear 12 drives the lead screw 8 to rotate. Since the limiting sleeve 7 is movably connected to the lead screw 8 through threads, the limiting sleeve 7 will slide along the lead screw 8. Then the inner wall of the limiting sleeve 7 will squeeze the outside of the limiting plate 9. Then the limiting plate 9 will rotate around the rotating shaft 20 and retract into the straight groove 16. Then the limiting plate 9 will squeeze the springs 13 arranged on both sides. At the same time, one end of the limiting plate 9 will gradually slide out of the limiting groove 14. When the limiting plate 9 completely enters the straight groove 16, stop rotating the control sleeve 6. Then one end of the limiting plate 9 completely slides out of the limiting groove 14. Then the push spring 21 pushes the push plate 22 to reset. Then the push plate 22 will push the splicing rod 15 to move, causing the splicing rod 15 to slide out of the splicing sleeve 10. Then pull the grip 25 to one side, and the grip 25 can drive the splicing rod 15 connected by the connecting rod 26 to slide out of the splicing sleeve 10 through the connecting rod 26. Then replace the grip 25. Then take out the replaced grip 25. Then insert the splicing rod 15 connected by the connecting rod 26 into the splicing sleeve 10. Then one end of the splicing rod 15 will squeeze the push spring 21 through the push plate 22. When the push spring 21 is squeezed to the limit, reverse-rotate the just-mentioned control sleeve 6. The control sleeve 6 drives the toothed ring 11 to reverse-rotate. Then the toothed ring 11 drives the gear 12 meshed with it to reverse-rotate. Then the gear 12 drives the lead screw 8 to reverse-rotate. Then the limiting sleeve 7 will slide reversely along the lead screw 8 to reset. Then the spring 13 will push the limiting plate 9 to rotate around the rotating shaft 20 to reset. Then both ends of the limiting plate 9 will move out of the straight groove 16. Then one end of the limiting plate 9 will enter the limiting groove 14. When the control sleeve 6 is completely reset, stop rotating the splicing sleeve 10. Then release the grip 25 and the splicing sleeve 10. Then the push spring 21 pushes the push plate 22 to reset, causing the push plate 22 to push the splicing rod 15 to move. Then the side wall of the limiting groove 14 will press one end of the limiting plate 9, so as to ensure the quick and stable installation of the grip 25.

[0042] When the device needs to be used, first replace the corresponding grip 25. Then hold the grip 25 connected to one end of the fixed rod 23 with one hand, and then hold the grip 25 connected to one end of the movable rod 24 with the other hand. Then align the flared opening 17 provided on one side of the sampling bucket 1 with the vegetable to be sampled, so that the vegetable to be sampled enters the sampling bucket 1 through the flared opening 17. Then keep the grip 25 connected to one end of the fixed rod 23 stationary, and then move the grip 25 connected to one end of the movable rod 24. Then the grip 25 will drive the movable rod 24 to rotate around the fixed shaft 5 through components such as the connecting rod 26. Then the movable rod 24 will drive the movable scissors 4 connected to the other end to move around the fixed shaft 5. Then the movable scissors 4 will cooperate with the fixed scissors 3 to cut and sample the vegetable to be sampled. Then the cut vegetable will fall into the sampling bin 2 connected to one side of the sampling bucket 1. Then put down the sampling bucket 1 and rotate the sampling bin 2. Since the sampling bin 2 is detachably installed on one side of the sampling bucket 1 through threads, then the sampling bin 2 will be removed from one side of the sampling bucket 1. Then take away the sampling bin 2 and the cut vegetable for testing. Then a new sampling bin 2 can be installed on one side of the sampling bucket 1 for re-sampling.
