Description

Technical Field

[0001] This invention relates to the field of geological exploration equipment technology, specifically a geological exploration sampler. Background Technology

[0002] With the rapid development of mineral resource exploration, engineering geological survey, and ecological environment monitoring, the accuracy, efficiency, and safety of geological sample collection have become core factors affecting the reliability of exploration results. In current geological exploration operations, sample collection, as a fundamental step, must address complex and diverse geological conditions (such as hard rock layers, loose soil layers, and strata with high water content), while also placing higher demands on the precise control of sampling depth, the stability of equipment operation, and ease of operation. From the perspective of sampling depth control, traditional equipment lacks an integrated depth monitoring mechanism and relies heavily on manual measurement with a tape measure or estimation based on experience. This is not only cumbersome to operate, but also prone to errors in depth recording due to human reading errors or equipment shaking. This often results in problems such as sampling too shallow and failing to obtain the target stratum sample, or sampling too deep and causing sample mixing, which seriously affects the accuracy of subsequent detection and analysis. Furthermore, the drilling components lack effective anti-sway constraints. During the descent of the sampling tube and drilling cover, radial shaking is easily generated due to uneven stratum resistance. This may not only collide with the support and cause component damage, but also cause the collected samples to spill or lose integrity, making it difficult to meet the requirements for high-quality sampling. Therefore, a geological exploration sampler is proposed to address the above problems. Summary of the Invention

The mounting parts facilitate the disassembly and replacement of the sampling tube and the drilling cover, adapting to the sampling needs of different geological conditions.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0021] Please see Figures 1-9 The present invention provides a technical solution: A geological exploration sampler includes a support frame 1, an movable groove 2 inside the support frame 1, a drilling sampling mechanism 3 inside the support frame 1, a distance observation mechanism 4 outside the drilling sampling mechanism 3, and a sway-resistant mechanism 5 inside the support frame 1. The drilling and sampling mechanism 3 includes a threaded tube 31, a lead screw 32 is connected to the inside of the threaded tube 31, a rotating handle 33 is fixedly connected to the top of the lead screw 32, a sampling tube 34 is fixedly connected to the bottom of the lead screw 32, and a drilling cover 35 is installed on the outside of the sampling tube 34. The distance observation mechanism 4 includes a movable ring 41, a ball bearing 42 fixedly connected to the outer side of the drill cover 35, a rotating groove 43 opened in the inner wall of the movable ring 41, a movable plate 44 fixedly connected to the outer side of the movable ring 41, a pointer 45 fixedly connected to the end of the movable plate 44 away from the movable ring 41, a movable groove 46 opened in the side wall of the support frame 1, and a scale plate 47 provided on the outer side of the movable groove 46. The anti-sway mechanism 5 includes a connecting plate 51, a rotating rod 52 is rotatably connected between the connecting plates 51, a connecting rod 53 is fixedly connected to the outside of the rotating rod 52, and a first clamping cover 54 and a second clamping cover 55 are fixedly connected to the outside of the connecting rod 53.

[0022] It should be noted that: the threaded tube 31 is fixedly connected to the top of the support frame 1, the sampling tube 34 and the drilling cover 35 are movably connected inside the support frame 1, and the initial position of the drilling cover 35 is directly above the movable groove 2. The balls 42 are evenly distributed on the outside of the drilling cover 35, and the end of the balls 42 away from the drilling cover 35 is rotatably connected inside the rotating groove 43. The movable ring 41 is rotatably connected to the outside of the drilling cover 35. One end of the moving plate 44 is slidably connected inside the moving groove 46. The pointer 45 is movably connected to the outside of the scale plate 47 through the moving plate 44, and the pointer 45 is located on the outside of the support frame 1. The connecting plate 51 is fixed and symmetrically distributed inside the support frame 1. The first clamping cover 54 and the second clamping cover 55 are movably connected inside the support frame 1 through the cooperation of the rotating rod 52 and the connecting rod 53.

[0023] Furthermore, the support frame 1 serves as the basic framework of the entire sampler, providing a mounting and support carrier for all functional mechanisms. It has an internal movable groove 2 to allow space for the vertical movement of the borehole cover 35 and the sampling tube 34. Anti-slip pads 11, made of a high-friction coefficient material, are symmetrically fixed to the bottom to increase contact friction with the ground, preventing overall equipment displacement during sampling and ensuring operational stability. Simultaneously, the support frame 1 has a movable groove 46 on its side wall and a scale plate 47 on its outer side, providing an installation and observation base for the distance observation mechanism 4.

[0024] Specifically: The drilling sampling mechanism 3 is the core structure for geological sample collection. It mainly consists of a threaded tube 31, a lead screw 32, a rotating handle 33, a sampling tube 34, a drilling cover 35, and an installation component 36. The threaded tube 31 is fixedly connected to the top of the support frame 1 and is threadedly engaged with the lead screw 32 to form an adjustable lifting transmission structure. The rotating handle 33 is fixed to the top of the lead screw 32, which is convenient for workers to manually apply force to control the lifting. The bottom is fixedly connected to the sampling tube 34, which is used to directly contain the collected geological samples. The drilling cover 35 is movably sleeved on the outside of the sampling tube 34 and is movably connected to the sampling tube 34 through the installation component 36 to ensure that the two can move synchronously without relative displacement. The bottom of the drilling cover 35 is uniformly fixed with conical columns 351 made of hard alloy material, which can contact the geological surface first during sampling and help break through the hard surface structure, reducing sampling resistance.

[0025] Furthermore, the distance observation mechanism 4 is used to monitor the borehole sampling depth in real time. It consists of a movable ring 41, ball bearings 42, rotating groove 43, moving plate 44, and pointer 45. The movable ring 41 is fitted on the outside of the borehole cover 35. The rotating groove 43 is opened on its inner wall and rotates in cooperation with the ball bearings 42 that are evenly distributed on the outside of the borehole cover 35. This ensures that the movable ring 41 moves up and down synchronously with the borehole cover 35 and reduces the frictional resistance between the two. The moving plate 44 is fixedly connected to the outside of the movable ring 41. The end of the moving plate 44 away from the movable ring 41 passes through the moving groove 46 of the support frame 1 and fixes the pointer 45. The pointer 45 is located outside the scale plate 47 and can move synchronously with the moving plate 44. The staff can intuitively read the sampling depth by observing the position of the pointer 45 on the scale plate 47.

[0026] As a further implementation of this scheme, the bottom of the support frame 1 is fixedly connected to an anti-slip pad 11, the outer side of the second clamping cover 55 is fixedly connected to a stabilizing plate 56, the outer side of the stabilizing plate 56 is fixedly connected to a movable tube 57, the inside of the movable tube 57 is movably latched to a positioning rod 58, the outer side of the positioning rod 58 is fixedly connected to a pulling cover 59, a compression spring 510 is sleeved on the positioning rod 58, a positioning hole 511 is opened in the side wall of the first clamping cover 54, an installation part 36 is provided between the drilling cover 35 and the sampling tube 34, and a conical column 351 is fixedly connected to the bottom of the drilling cover 35.

[0027] It should be noted that: the No. 1 clamping cover 54 and the No. 2 clamping cover 55 are symmetrically distributed on the outside of the drilling cover 35, and rubber pads are provided on the inside of the No. 1 clamping cover 54 and the No. 2 clamping cover 55. Anti-slip pads 11 are symmetrically distributed at the bottom of the support frame 1. Stabilizing plates 56 are symmetrically distributed on the outside of the No. 2 clamping cover 55. The positioning rod 58 passes through the inside of the stabilizing plate 56, and the end of the positioning rod 58 away from the pulling cover 59 is located inside the positioning hole 511. The conical columns 351 are evenly distributed at the bottom of the drilling cover 35.

[0028] Furthermore, the anti-sway mechanism 5 is used to prevent the drill cover 35 from shaking during drilling. It consists of a connecting plate 51, a rotating rod 52, a connecting rod 53, a first clamping cover 54, a second clamping cover 55, a stabilizing plate 56, a movable tube 57, a positioning rod 58, a pulling cover 59, a compression spring 510, and a positioning hole 511. The connecting plate 51 is symmetrically fixed inside the support frame 1, and the rotating rod 52 is rotatably connected to it. The connecting rod 53 is fixed to the outside of the rotating rod 52. The connecting rod 53 is fixedly connected to the first clamping cover 54 and the second clamping cover 55 respectively, so that the two clamping covers can rotate around the rotating rod 52. The two clamping covers are symmetrically distributed on the outside of the drill cover 35, and rubber pads are attached to the inside of each cover, which can enhance the clamping friction and prevent damage to the drill cover 35.

[0029] Specifically: The stabilizing plate 56 is symmetrically fixed on the outside of the second clamping cover 55, and the movable tube 57 is fixed on it. The positioning rod 58 is movably engaged inside the movable tube 57. One end of the positioning rod 58 is fixed to the pull cover 59, and the other end can be inserted into the positioning hole 511 on the side wall of the first clamping cover 54. A compression spring 510 is sleeved on the positioning rod 58. The two ends of the compression spring 510 abut against the movable tube 57 and the pull cover 59 respectively. The spring force can realize the automatic reset and locking of the positioning rod 58, ensuring the stability of the clamping state.

[0030] Workflow: When the geological exploration sampler is in operation, it is first placed stably by the anti-slip pads 11 symmetrically distributed at the bottom of the support frame 1. Then, the pre-sampling stabilization operation is performed: the rotating rod 52 fixed inside the support frame 1 by the connecting plate 51 drives the connecting rod 53 to rotate the first clamping cover 54 and the second clamping cover 55 symmetrically distributed on the outside of the drill cover 35 inward until the inner rubber pad is in contact with the drill cover 35. Then, the pulling cover 59 is pulled to move the positioning rod 58 in the movable tube 57. The compression spring 510 is compressed. After the first clamping cover 54 and the second clamping cover 55 are completely in contact, the pulling cover 59 is released. The compression spring 510 returns to its original position and pushes the positioning rod 58 through the stabilizing plate 56 and into the positioning hole 511 of the first clamping cover 54, thus stabilizing the drill cover 35. Then, the drilling sampling mechanism 3 is started. Since the threaded tube 31 is fixed on the top of the support frame 1, the rotating handle 33 is turned to drive the screw 32 to move downward in the threaded tube 31, thereby pushing the sampling tube 34 and the drilling cover 35, which is initially located directly above the movable groove 2, to move downward. The evenly distributed conical columns 351 at the bottom of the drilling cover 35 first contact the geological surface and assist in drilling. The sampling tube 34 achieves synchronous sampling by cooperating with the mounting part 36 between it and the drilling cover 35. During the drilling and sampling process, the distance observation mechanism 4 works synchronously. Because the ball bearings 42 evenly distributed on the outside of the drill cover 35 are rotatably connected to the rotating groove 43 on the inner wall of the movable ring 41, the movable ring 41 moves downward with the drill cover 35, causing the movable plate 44, which is fixedly connected to the movable ring 41, to slide in the moving groove 46 on the side wall of the support frame 1. This causes the pointer 45 fixed at the other end of the movable plate 44 to move outside the scale plate 47. The staff can observe the drilling and sampling depth in real time by observing the position change of the pointer 45 on the scale plate 47 until the collection of the required geological samples is completed.

[0031] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
