Description

Technical Field

[0001] This utility model relates to the field of geological core sampling technology, specifically a portable geological core sampling positioning device. Background Technology

[0002] Rock cores are cylindrical rock samples drilled from the ground using specialized equipment such as ring drill bits during geological exploration. Their diameter typically ranges from 25 millimeters to 1.5 meters, depending on the drilling purpose (such as mineral exploration, hydrogeology, or scientific drilling). Rock cores preserve the original structure and composition of the strata and are known as "the rings of the earth," revealing key information such as crustal evolution and paleoclimate changes. Sampling equipment is required when taking rock core samples.

[0003] Existing patent CN221993065U discloses a core sampler with an anti-jamming structure, relating to the field of core sampling technology. It includes a receiving frame and a sampling component. A counterweight is installed on the outer side of the lower end of the receiving frame, and a stabilizing frame is installed on the upper end of the counterweight. A receiving block is disposed inside the receiving frame, and a sampling component is disposed at the lower end of the receiving block. The sampling component includes a drive motor, a mounting rod, a limiting groove, a core tube, a docking block, a mounting through hole, a receiving ring, a pneumatic rod, and a clamping ring. The front end of the drive motor is connected to the mounting rod, and a limiting groove is formed on the upper outer end of the mounting rod. The core tube is disposed at the lower end of the mounting rod, and a docking block is added to the upper end of the core tube. This core sampler with an anti-jamming structure avoids the problem of cores easily getting trapped in the core tube, which is common in most core samplers, due to the lack of an anti-jamming structure, thus improving the overall practicality of the core sampler.

[0004] Based on the search of the aforementioned patents and in conjunction with existing geological core sampling devices, it was found that while current core sampling devices can sample rock cores, the drilling process can cause debris to fly out and collide with workers, increasing the risk of accidents. Furthermore, the support frame can easily tilt due to different terrains, affecting the sampling operation and reducing its practicality. Utility Model Content

This addresses the problems mentioned in the background art, such as the fact that while existing core sampling devices can sample cores, drilling is required during sampling, and debris can easily fly out and collide with workers, increasing the risk of accidents. Furthermore, the support frame can easily tilt due to different terrains, affecting the sampling operation and reducing its practicality.

The start of the first motor 25 can drive the bidirectional screw 24 to rotate, the bidirectional screw 24 can drive the two sliders 23 to move in opposite directions, and then drive the two moving plates 26 and the moving rod 27 to move. The moving rod 27 can drive the shield 28 to move. After the two shields 28 are combined, they can cover the core tube 55, thereby preventing the flying debris from injuring people, protecting the staff and reducing the danger. There are two support grooves 41 on the side of the moving frame 21 away from the slide chute 22, and the support grooves 41 are slidably connected to... Support block 42 is fixedly connected to movable plate 26.

[0020] Working principle: During operation, push the fixed base 1 to the appropriate position, and then, depending on the terrain, selectively rotate the four handles 34. Rotating the handles 34 drives the rotating plate 33 to rotate, which in turn drives the lifting screw 32 to rotate. Rotating the lifting screw 32 drives the support base 35 to move vertically, bringing it into contact with the ground and leveling the fixed base 1. Then, start the first motor 25, which drives the bidirectional screw 24 to rotate. Rotating the bidirectional screw 24 drives the two sliders 23 to move towards the center. The movement of the sliders 23 drives the moving plate 26 to move, and the movement of the moving plate 26 drives the moving rod 27 to move. The movement of the moving rod 27 can drive the movement of the shielding cover 28. After the two shielding covers 28 are combined, they can shield the core tube 55. The cylinder 61 is activated, which can push the moving frame 21 to move vertically. The moving frame 21 can drive the moving rod 27 and the shielding cover 28 to move, so that the shielding cover 28 contacts the ground. The second motor 53 is activated, which can drive the core tube 55 to rotate. The hydraulic cylinder 51 can push it to move downward, so that drilling and sampling can be carried out. The shielding cover 28 can prevent the flying debris from injuring people. The above is the working process of the whole device.
