[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] As described in the background art, the first drill rod of the above-mentioned sampling device has a fixed length, which is inconvenient for transportation and storage, especially in situations requiring remote operation or complex terrain, where transportation and carrying are quite difficult.

[0025] To solve this technical problem, this utility model provides a novel sampling device.

[0026] For details, please refer to Figures 1-5 A novel sampling device specifically includes: a first drill rod 1, a second drill rod 2 disposed at the top of the first drill rod 1, a connecting mechanism disposed on the inner side of the top of the first drill rod 1 for connecting and fixing the first drill rod 1 and the second drill rod 2, a collection bucket 3 fixed at the bottom of the first drill rod 1, a discharge mechanism disposed on the inner side of the first drill rod 1 for assisting the collection bucket 3 in discharging material, and handles 4 fixed at both ends of the top of the second drill rod 2.

[0027] The present invention provides a novel sampling device. The design of the connecting mechanism allows the first drill rod 1 and the second drill rod 2 to be quickly disassembled. This segmented design makes the entire sampling device more flexible and convenient to transport and store. The discharge mechanism can quickly separate the soil from the sampling bucket 3 after sampling, reducing the amount of soil adhering to the sampling bucket 3, thereby accelerating the removal speed of soil samples.

[0028] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0029] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0030] Example 1

[0031] Reference Figures 1-4 A novel sampling device includes a first drill rod 1, a second drill rod 2 at the top of the first drill rod 1, a connecting mechanism on the inner side of the top of the first drill rod 1 for connecting and fixing the first drill rod 1 and the second drill rod 2, a collection bucket 3 fixed at the bottom of the first drill rod 1, a discharge mechanism on the inner side of the first drill rod 1 for assisting the collection bucket 3 in discharging material, and handles 4 fixed at both ends of the top of the second drill rod 2.

[0032] The connecting mechanism includes a bidirectional threaded rod 5, a knob 6, a snap-fit ​​plate 7, and a connecting rod 8. The bidirectional threaded rod 5 is rotatably connected to the inner side of the top of the first drill rod 1. One end of the bidirectional threaded rod 5 passes through the first drill rod 1 and is fixed with the knob 6. A protective component is provided at the top of the outer side of the first drill rod 1. The protective component is used to protect the knob 6. Both ends of the outer side of the bidirectional threaded rod 5 are threadedly connected with snap-fit ​​plates 7. The snap-fit ​​plates 7 are snapped with the second drill rod 2. Both snap-fit ​​plates 7 are slidably connected to the first drill rod 1. Both sides of the inner side of the two snap-fit ​​plates 7 are slidably connected with connecting rods 8. Both connecting rods 8 are fixed to the first drill rod 1.

[0033] The design of the connecting mechanism allows for quick disassembly of the first drill rod 1 and the second drill rod 2. This segmented design makes the entire data acquisition device more flexible and convenient to transport and store.

[0034] The protective assembly includes a fixed plate 10, a first sliding plate 11, a connecting plate 12, a second spring 13, and a lifting plate 14. Two fixed plates 10 are fixed to the top of the outer side of the first drill rod 1. The first sliding plate 11 is slidably connected to the inner side of the fixed plate 10. A connecting plate 12 is fixed to one end of each of the two first sliding plates 11. A knob 6 is located between the two connecting plates 12. A second spring 13 is fixed to one side of the first sliding plate 11. The second spring 13 is located inside the fixed plate 10. One end of the second spring 13 is fixed to the fixed plate 10. A lifting plate 14 is fixed to one end of the connecting plate 12.

[0035] The protective components effectively prevent the snap-on board 7 from being accidentally touched, which could lead to a loose connection.

[0036] The first drill rod 1 has a docking groove 15 on both sides of the inner side of the top. The bottom of the second drill rod 2 is fixed with a docking rod 16 at the position corresponding to the docking groove 15. The size of the docking groove 15 is the same as the outer size of the docking rod 16.

[0037] The design of the docking groove 15 and the docking roller 16 facilitates alignment when the first drill rod 1 and the second drill rod 2 are connected.

[0038] Example 2

[0039] Reference Figure 5 A novel sampling device includes a discharge mechanism comprising a second sliding plate 17, a connecting rod 18, a third spring 19, and a third sliding plate 20. The second sliding plate 17 is slidably connected to the inner side of the first drill rod 1. The connecting rod 18 is fixed to the bottom of the second sliding plate 17 and is slidably connected to the collection bucket 3. The third spring 19 is sleeved on the outer side of the connecting rod 18 and is located inside the first drill rod 1. The third sliding plate 20 is fixed to the bottom of the connecting rod 18 and is slidably connected to the collection bucket 3.

[0040] The discharge mechanism can quickly separate the soil from the collection bucket 3 after sampling, reducing the amount of soil adhering to the collection bucket 3, thereby speeding up the removal of soil samples.

[0041] A first spring 9 is fixed at one end of the two snap-fit ​​plates 7 that are close to each other. The setting of the first spring 9 can, to a certain extent, offset the loosening of the connection between the bidirectional threaded rod 5 and the snap-fit ​​plate 7 caused by vibration.

[0042] The usage process of the novel sampling device provided by this utility model is as follows: When the first drill rod 1 and the second drill rod 2 need to be combined and spliced, the two docking rods 16 at the top of the second drill rod 2 are inserted into the inner side of the docking groove 15. Since the lifting plate 14 is fixedly connected to the connecting plate 12, the lifting plate 14 is pulled to one side. The movement of the lifting plate 14 drives the connecting plate 12 to move, so that the first sliding plate 11, which is fixedly connected to the connecting plate 12, slides inside the fixed plate 10. At this time, the second spring 13, which is fixedly connected to the first sliding plate 11, is compressed by the first sliding plate 11. At this time, the knob 6 is rotated. Since the knob 6 is fixedly connected to the bidirectional threaded rod 5, the rotation of the knob 6 drives the bidirectional threaded rod 5 to rotate, so that the two snap-fit ​​plates 7, which are threadedly connected to the bidirectional threaded rod 5, move back to back, so that the snap-fit ​​plates 7 snap with the second drill rod 2, thereby completing the connection of the first drill rod 1 and the second drill rod 2.

[0043] The design of the connecting mechanism allows the first drill rod 1 and the second drill rod 2 to be quickly disassembled. This segmented design makes the entire data acquisition device more flexible and convenient to transport and store.

[0044] When sampling is completed through the collection bucket 3 and the soil sample needs to be removed from the inside of the collection bucket 3, the second sliding plate 17 is slid down. Since the second sliding plate 17 is fixedly connected to the connecting rod 18, the movement of the second sliding plate 17 drives the connecting rod 18 to move. At this time, the movement of the second sliding plate 17 compresses the third spring 19 sleeved on the outside of the connecting rod 18, thereby causing the third sliding plate 20, which is fixedly connected to the connecting rod 18, to slide inside the collection bucket 3. This movement of the third sliding plate 20 pushes the soil sample out from inside the collection bucket 3, and the second sliding plate 17 is pushed back to its original position under the action of the elastic force of the third spring 19.

[0045] The discharge mechanism can quickly separate the soil from the collection bucket 3 after sampling, reducing the amount of soil adhering to the collection bucket 3, thereby speeding up the removal of soil samples.

[0046] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to specific implementations. Clearly, many modifications and variations can be made based on the content of this specification.
