Description

Technical Field

[0001] This utility model relates to the field of geological sampling technology, and more specifically to a sampling device for geological exploration. Background Technology

[0002] In geological exploration, sampling is a crucial step in obtaining subsurface geological information. Traditional geological exploration sampling devices often suffer from the following problems: Firstly, the sampling devices have relatively limited functions, making it difficult to classify samples according to geological conditions at different depths, resulting in samples from different depths being mixed together and affecting the accuracy of subsequent geological analysis. Secondly, although stratified sampling devices are available on the market, sample retrieval is often difficult or cumbersome after collection, thus reducing the overall efficiency of the sampling process. Furthermore, some sampling devices are inconvenient to fix and move, making operation cumbersome and reducing the efficiency of geological exploration. Therefore, there is a need for a geological exploration sampling device that can solve the above problems. Utility Model Content

[0003] This invention provides a sampling device for geological exploration to solve the problems existing in the background art.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: A sampling device for geological exploration includes a main body, a sampling hole in the middle of the main body, fixing components symmetrically installed on both sides of the main body, a lifting component on the top of the main body, and a sampling component installed on the lifting component. The sampling assembly includes a drill cylinder driven by a rotary motor. A drill bit is fixedly connected to the bottom of the drill cylinder. An adjustment assembly is provided inside the drill cylinder. A collection cylinder is fixedly connected to the bottom of the adjustment assembly. A sampling port is opened on the outer side of the bottom of the drill cylinder. A sampling frame is installed at the sampling port. The collection cylinder is divided into several collection chambers by a partition. Each of the collection chambers has a feed inlet that matches the sampling port.

[0005] The lifting assembly includes a sliding rod, a lead screw, a lifting motor, and a fixed plate. The sliding rod and the lead screw are symmetrically arranged on both sides of the sampling hole. The two ends of the fixed plate pass through the sliding rod and the lead screw, respectively. One end of the sliding rod is fixedly connected to the main body, and the other end is slidably connected to the fixed plate. One end of the lead screw is fixedly connected to the main body, and the other end is threadedly connected to the fixed plate. The lifting motor is fixedly connected to the top center of the fixed plate, and the output end of the lifting motor passes through the fixed plate and is fixedly connected to the top of the drill barrel.

[0006] The adjustment assembly includes an adjustment motor, which is fixedly connected to the upper end of the inner wall of the drill barrel. A connecting rod is fixedly connected to the output end of the adjustment motor, and the connecting rod is fixedly connected to the top of the collection cylinder.

[0007] Furthermore, baffles are threaded to both ends of the collecting cylinder. The top of the baffle at the upper end of the collecting cylinder is fixedly connected to the connecting rod, and an arc-shaped groove is provided at the bottom of the baffle at the lower end of the collecting cylinder, with a handle fixedly provided at the arc-shaped groove.

[0008] Furthermore, the fixing component includes a fixing screw and a rotating handle. The rotating handle is located on the top of the fixing screw, and the fixing screw is used to insert into the ground when the main body is fixed.

[0009] Furthermore, the upper end of the drill barrel is connected by a flange and fixed by bolts.

[0010] Furthermore, a push rod is provided on one side of the main body.

[0011] Furthermore, four wheels are symmetrically arranged at the bottom of the main body.

[0012] This utility model has the following beneficial effects: (1) The drill barrel of this utility model is equipped with an adjustment component. The bottom of the adjustment component is fixedly connected to a collection barrel that is divided into three collection chambers by a partition. Each collection chamber is provided with a feed port that matches the sampling port on the outside of the bottom of the drill barrel. During sampling, the rotary motor drives the drill barrel to rotate and the drill bit drills into the ground. When the required sampling depth is reached, the rotary motor is reversed. At this time, the sample to be collected enters the collection chamber through the sampling port and the feed port under the action of the collection frame. In this way, the position of the collection barrel can be precisely adjusted according to actual needs, so that samples at different depths can enter different collection chambers respectively, thereby achieving accurate classification and sampling.

[0013] (2) By setting up a lifting component, when the lifting motor is working, it drives the lead screw to rotate. Since the lead screw is threadedly connected to the fixed plate, it drives the fixed plate to move up and down along the sliding rod, thereby driving the drill barrel to move up and down. This mechanical transmission method is simple to operate and can accurately control the descent and lifting height of the drill barrel to meet the sampling requirements of different depths. Operators do not need to manually and cumbersomely adjust the position of the device. They only need to start the lifting motor to complete the depth adjustment, which greatly saves time and manpower and improves sampling efficiency.

[0014] (3) The collection tube of this utility model is threaded with baffles at both ends. The top of the upper baffle is fixedly connected to the connecting rod, and the bottom of the lower baffle is provided with an arc-shaped groove and a handle. After the sample is collected, the operator only needs to rotate the collection tube to separate it from the upper baffle, and then rotate the handle of the lower baffle to separate it from the collection tube, so that the sample can be easily taken out. This design avoids the problem of the sample sticking tightly to the collection device and being difficult to remove, and reduces the time and difficulty of sample removal.

Detailed Implementation

[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0017] A sampling device for geological exploration, as shown in the attached document. Figure 1-4 As shown, the device includes a main body 1 with a sampling hole 2 in the middle. Fixing components are symmetrically installed on both sides of the main body 1. In this embodiment, the fixing components specifically include a fixing screw 21 and a rotating handle 22. The rotating handle 22 is located on the top of the fixing screw 21. The fixing screw 21 is used to insert into the ground when the main body 1 is fixed, thereby firmly fixing the device to the ground and preventing the device from shaking or shifting during sampling. A lifting component is provided on the top of the main body 1, which allows the sampling component to move up and down to meet sampling needs at different depths. The sampling component is installed on the lifting component. The sampling assembly includes a drill cylinder 3, which is driven by a rotary motor 4. A drill bit 5 is fixedly connected to the bottom of the drill cylinder 3. The rotary motor 4 drives the drill cylinder 3 to rotate, allowing the drill bit 5 to drill deeper into the ground for sampling. An adjustment assembly is provided inside the drill cylinder 3, and a collection cylinder 6 is fixedly connected to the bottom of the adjustment assembly. A sampling port 7 is opened on the outer side of the bottom of the drill cylinder 3, and a sampling frame 8 is installed at the sampling port 7. In this embodiment, the collection cylinder 6 is divided into three collection chambers 10 by a partition 9. Each of the three collection chambers 10 has an inlet 11 that matches the sampling port 7. During the sampling process, after the underground sample enters the drill cylinder 3 through the sampling port 7, the position of the collection cylinder 6 can be adjusted as needed so that samples at different depths enter the corresponding collection chambers 10 through the inlets 11, thereby achieving classified sampling.

[0018] The lifting assembly includes a sliding rod 12, a lead screw 13, a lifting motor 14, and a fixing plate 15. The sliding rod 12 and the lead screw 13 are symmetrically arranged on both sides of the sampling hole 2. The two ends of the fixing plate 15 pass through the sliding rod 12 and the lead screw 13, respectively. One end of the sliding rod 12 is fixedly connected to the main body 1, and the other end is slidably connected to the fixing plate 15. One end of the lead screw 13 is fixedly connected to the main body 1, and the other end is threadedly connected to the fixing plate 15. The lifting motor 14 is fixedly connected to the top of the middle of the fixing plate 15. The output end of the lifting motor 14 passes through the fixing plate 15 and is fixedly connected to the top of the drill barrel 3. When the lifting motor 14 is working, it drives the lead screw 13 to rotate. Since the lead screw 13 is threadedly connected to the fixing plate 15, it drives the fixing plate 15 to move up and down along the sliding rod 12, thereby driving the drill barrel 3 to move up and down to achieve sampling at different depths.

[0019] The adjustment assembly includes an adjustment motor 16, which is fixedly connected to the upper end of the inner wall of the drill barrel 3. A connecting rod 17 is fixedly connected to the output end of the adjustment motor 16. The connecting rod 17 is fixedly connected to the top of the collection cylinder 6. When the adjustment motor 16 is working, it drives the collection cylinder 6 to rotate through the connecting rod 17, so that the feed inlets 11 on different collection chambers 10 can be aligned with the sampling ports 7, thereby realizing the classified collection of samples at different depths.

[0020] The collection tube 6 is threaded with baffles 18 at both ends. The top of the baffle 18 at the upper end of the collection tube is fixedly connected to the connecting rod 17. The bottom of the baffle 18 at the lower end of the collection tube 6 is provided with an arc-shaped groove 19. A handle 20 is fixedly provided at the arc-shaped groove 19. After the sample is collected, the collection tube 6 is separated from the upper baffle 18 by rotating the collection tube 6. Then, the handle 20 of the lower baffle 18 is rotated to separate the lower baffle 18 from the collection tube 6, and then the sample is taken out.

[0021] Furthermore, to facilitate the removal of the collection tube 6, the upper end of the drill tube 3 is connected by a flange 23 and fixed by bolts 24. After the sample collection is completed, the flange 23 connection at the upper end of the drill tube 3 is separated by removing the bolts 24, and then the collection tube 6 can be removed.

[0022] Furthermore, to facilitate the movement of the device, a push rod 25 is provided on one side of the main body 1, and four moving wheels 26 are symmetrically arranged at the bottom of the main body 1.

[0023] Work process First, the device is moved to the ground where sampling is required using the moving wheels 26. Then, the device is fixed to the ground using the fixing components. After fixing, the lifting motor 14 is started to lower the drill barrel 3. When the drill bit 5 contacts the ground, the rotating motor 4 is started. Under the combined action of the lifting components and the rotating motor 4, the drill barrel 3 drills into the ground. When the required sampling depth is reached, the rotating motor 4 is reversed. At this time, the sample to be collected enters the collection chamber 10 through the collection frame. (It should be noted that when the rotating motor rotates forward, the soil will pass through the arc of the sampling frame 8 as it rotates.) (The sample will not enter the collection chamber 10). After collection, the rotation direction of the rotary motor 4 is changed, and the device continues to drill downward. When the next sampling depth is reached, the above sample collection process is repeated. This cycle continues until the sample collection is completed. After collection, the drill cylinder 3 is lifted by the lifting assembly, and the bolt 24 is removed. The upper end of the drill cylinder 3 is disassembled. The collection cylinder 6 is separated from the upper baffle 18 by rotating the collection cylinder 6. Then, the handle 20 of the lower baffle 18 is rotated to separate the lower baffle 18 from the collection cylinder 6, and the sample is taken out. Finally, the sampling work of the device is completed.
