Detailed Implementation

[0029] The technical solutions of the present invention will now be described with reference to the accompanying drawings.

[0030] It should be noted that similar reference numerals 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. Furthermore, in the description of this invention, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] Please refer to Figures 1-7 This invention provides a portable geological stratification sampling device for geological prospecting. Existing sampling devices involve inserting a sampling drill 101 into the soil to collect samples. When multiple layers of sampling are required, the sampling and placement process needs to be repeated, making the operation complicated and inefficient. In order to solve the above technical problems, this invention optimizes the sampling equipment to achieve the purpose of convenient stratification sampling.

[0032] As shown in the figure, the system mainly includes a positioning platform 100. Support legs 120 and a sampling drill 101 are located at the bottom of the positioning platform 100. The support legs 120 contain multiple telescopic joints for extension and retraction. The sampling drill 101 is powered by a drive motor 102, which is located at the top of the positioning platform 100. The drive motor 102 enables the sampling drill 101 to drill downwards. To control the downward rotation of the sampling drill 101, two columns 110 are also installed on the platform of the positioning platform 100, located on either side of the drive motor 102. A vertical plate 111 is installed on the top of each column 110. A threaded rod 112 is installed between the vertical plate 111 and the positioning platform 100. The end of the threaded rod 112 extends from the vertical plate 110. The threaded rod 112 extends outwards and is fitted with a first pulley 113. Additionally, a rotary motor 114 is installed near the top of the column 110. A second pulley 115 is installed on the output shaft of the rotary motor 114. The first pulley 113 and the second pulley 115 are connected by a belt. Driven by the rotary motor 114 and the belt, the threaded rod 112 is rotated. A movable plate 109 is fixedly connected to the side wall of the drive motor 102. The movable plate 109 has a screw hole and is fitted onto the threaded rod 112. The rotation of the threaded rod 112 causes the movable plate 109 to move up and down, which in turn drives the drive motor 102 downwards, and then drives the sampling drill 101 to move downwards to drill a hole.

[0033] To further improve the overall structure, a sliding groove is provided at the end of the moving plate 109, and a sliding column is provided on the column 110. The sliding column can be placed in the sliding groove, thereby increasing its stability in vertical movement. In actual operation, the moving plate is gradually driven downward by rotating the motor 114. The sampling drill 101 rotates through the soil under the action of the drive motor 102. When sampling is required, the sampling is performed through the sampling cylinder 200 set on the outer arm of the sampling drill 101. As shown in the figure, there is only one threaded rod 112, and the other can be a cylinder, which can be moved easily and achieve a stable effect.

[0034] The sampling cylinder 200 is fitted onto the outer arm of the sampling drill 101, and an indirect transmission assembly is provided between the sampling cylinder 200 and the sampling drill 101. The indirect transmission assembly includes an active drive ring tooth 103 provided on the outer arm of the sampling drill 101, and a driven meshing ring tooth 201 provided on the inner wall of the top of the sampling cylinder 200. The active drive ring tooth 103 can mesh with the driven meshing ring tooth 201, thereby driving the sampling cylinder 200 to rotate with the sampling drill 101. Under the rotation of the sampling cylinder 200, the current soil layer can be sampled. In order to facilitate sampling, several stirring teeth 203 are spirally arranged on the inner wall of the sampling cylinder 200, with the free end of the stirring teeth facing upward, so that the sampled soil can spiral upward to the bottom sampling port 202. A sampling ring cup 300 is provided outside the sampling port 202, and the sample coming out of the sampling port 202 is collected by the sampling ring cup 300.

[0035] During the lowering of the sampling drill 101, the sampling cylinder 200 does not rotate and therefore does not take samples. During this process, the sampling cylinder 200 is fixed at the bottom of the positioning platform 100, causing the active driving ring gear 103 and the driven meshing ring gear 201 to separate from each other. Specifically, an annular block plate 204 is provided at the top of the sampling cylinder 200, and an annular groove 104 that can accommodate the annular block plate 204 is provided at the corresponding position at the bottom of the positioning platform 100. An extension plate 105 is provided around the annular groove 104. The extension plate 105 can move towards the annular groove 104 to fix the annular block plate 204, thereby fixing the sampling cylinder 200.

[0036] The extension and retraction of the extension plate 105 are achieved by providing serrated bars 106 at the end of the extension plate 105, with drive gears 107 meshing between the serrated bars 106, and a drive motor 108 is provided on the top of the positioning platform 100. The drive motor 108 is connected to the drive gear 107 via a drive shaft. Driven by the drive shaft, the extension plate 105 that meshes with the drive gear 107 is driven, thereby realizing the action of extending or retracting into the annular groove 104. When sampling is not required, the sampling cylinder 200 is lifted upwards, and the ring plate 204 is placed in the ring groove 104. Then, the drive motor 102 causes the extension plate 105 to extend out and cover the ring groove 104, allowing the sampling cylinder 200 to fall. The extension plate 105 can only cover part of the ring. To facilitate the movement of the whole, the ring groove 104 can also be a through groove, so that the sampling cylinder 200 can move up and down with the sampling drill 101. The size of the sampling cylinder 200 can also be set in various ways to facilitate the installation of the sampling drill 101 according to its length.

[0037] To improve the stability of the device structure, there are two protruding plates 105 located on both sides of the annular groove 104. There can also be two drive motors 108. The two protruding plates 105 move relative to or in opposite directions, thereby fixing or releasing the sampling cylinder 200.

[0038] This embodiment provides another implementation structure. To make the structure of this device more convenient to operate and to increase the mechanical operating force, as shown in the figure, an extension plate 205 is also provided on the top of the ring block plate 204. The extension plate 205 has serrations. A first rotating gear 110 and a second rotating gear 111 are provided on the output shaft of the drive motor 108. The drive motor 108, the first rotating gear 110, and the second rotating gear 111 are all located above the positioning platform 100. The bottom of the first rotating gear 110 is connected to a reversing gear, which meshes with the serrations on the extension plate 205. The drive shaft of the drive gear 107 also synchronously drives a driven gear 112. The driven gear 112 is located above the positioning platform 100. The driven gear 112 meshes with a transfer plate 113, which has serrations and is connected to the second rotating gear. 111 meshing, as shown in the figure, the driving process is as follows: Under the action of the transmission motor 108, the first rotating gear 110 and the second rotating gear 111 rotate clockwise. The second rotating gear 111 drives the transfer plate 113 to move to the left, thereby causing the driven gear 112 and the driving gear 107 to rotate clockwise. When the driving gear 107 moves clockwise, it drives the sawtooth strip 106 and the extension plate 105 to move towards the annular groove 104, thereby fixing the annular block plate 204 of the sampling cylinder 200. Under the drive of the first rotating gear 110, the reversing gear rotates counterclockwise, thereby meshing the extension block on the annular block plate 204 to move upward, thereby pulling the sampling cylinder 200 upward and placing the annular block plate 204 in the annular groove 104. After the annular block plate 204 is placed in the annular groove 104, the extension plate 105 will be placed at the bottom of the annular groove 104, thereby achieving the purpose of fixing.

[0039] After the sampling cylinder 200 is lowered, its active drive gear 107 engages with the driven meshing gear, thereby enabling the sampling cylinder 200 to rotate and achieve the sampling purpose. The sampled soil is collected through the sampling ring cup 300. The structure of the sampling ring cup 300 is shown in the figure, mainly including the ring cup body 310, the adapter body 320, and the connecting collar 330. A concave annular groove 104 is provided on the outer arm of the sampling cylinder 200. The connecting collar 330 is fitted into the concave annular groove 104, and the ring cup body 310 and the connecting collar 330 are connected to form a mutual connection. The ring cup body 310 has a stable structure and is provided with multiple sample-dividing plates 311 to form multiple sampling cavities. One end of the adapter 320 is connected to the top of the ring cup body 310, and the other end is correspondingly set at the sample outlet 202. The adapter 320 includes a ring inclined plate and a partition plate 321 set on the ring inclined plate. The partition plate 321 and the sample-dividing plates 311 are correspondingly set to form independent transport channels and sample storage cavities. The sampling ring cup 300 can rotate on the outer arm of the sampling cylinder 200, so that different layers of soil can exist in different sampling cavities.

[0040] To facilitate the installation and removal of the sampling ring cup 300, the ring cup body 310, the adapter 320, and the connecting collar 330 are all structures made of two semi-circular pieces joined together.

[0041] The workflow of this invention is as follows:

[0042] The rotating motor 114 drives the first pulley 113 and the second pulley 115 to rotate, thereby causing the threaded rod 112 to rotate, which in turn drives the moving plate 109 to gradually move downward. Under the action of the drive motor 102, the sampling drill 101 rotates the soil. During the drilling process, the sampling cylinder 200 is fixedly placed on the top of the positioning platform 100, so that its active drive ring tooth 103 is separated from the driven meshing ring tooth 201. When the drilling reaches the set soil layer, the transmission motor 108 causes its extension plate 105 to move away from the ring groove 104, so that the sampling cylinder 200 is put into the ring groove 104, and the active drive ring tooth 103 and the driven meshing ring tooth 201 are engaged. When the drive motor 102 rotates, the sampling cylinder 200 samples the soil. The sample is discharged from the sampling port 202 and placed in the sampling chamber.

[0043] This device places the sampling ring cup 300 on the outer wall of the sampling cylinder 200, allowing the sample taken through the sampling cylinder 200 to be quickly transferred, improving the classification and management of the sample. It can perform layered sampling without the need to reposition the device, thereby improving the sampling efficiency.

[0044] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
