Description

Technical Field

[0001] This utility model relates to the field of sampler technology, and in particular to a geological drilling sampler. Background Technology

[0002] With the continuous development of the global economy, the demand for energy and mineral resources continues to rise. The exploration and development of oil, natural gas and metal minerals cannot be separated from geological drilling and sampling. By drilling and sampling to obtain underground rock cores and samples, and analyzing their composition, structure and characteristics, the distribution, reserves and quality of resources can be determined, providing key basis for resource extraction. Traditional sampling methods are difficult to meet the needs of large-scale and high-precision exploration, prompting the emergence of more efficient and accurate geological drilling and sampling equipment.

[0003] A search revealed Chinese Patent Publication No. CN214844092U, which discloses a stable petroleum geological soil sampler. It includes: a frame, a fixed frame mounted on the frame, a soil collection box within the fixed frame, and a soil drilling component for soil excavation within the soil collection box. A support frame is mounted on the frame, and a drive component is mounted on the support frame to drive the soil collection box to move up and down. A stabilizing device is mounted on the frame. Through the arrangement of the soil drilling component, drive component, and stabilizing device, the soil sampler achieves automation, avoids shaking during soil excavation, improves the stability of the sampler, accelerates soil sampling speed, and enhances sampling efficiency and practicality. However, this invention does not consider that if the soil at the bottom cannot be conveyed upwards during sampling, the operator may be unable to determine the depth of the extracted soil, thus reducing the accuracy of the test. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a geological drilling sampler, which aims to improve the problem in the prior art that if the soil at the bottom cannot be conveyed upwards, the staff will not be able to judge the depth of the soil to be extracted, thus reducing the accuracy of the test.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a geological drilling sampler, comprising a shell, wherein a motor is fixedly connected to the top left and right sides of the inner wall of the shell, an elliptical disk is fixedly connected to the output end of the motor, a hollow tube is slidably connected to the middle of the inner wall of the shell, a drill bit is fixedly connected to the bottom of the hollow tube, a fixing plate is fixedly connected to the top of the outer wall of the hollow tube, a waterproof shell is fixedly connected to the top of the hollow tube, a motor is fixedly connected to the inner wall of the waterproof shell, a spiral blade is fixedly connected to the output end of the motor, and an auxiliary mechanism is provided on the inner wall of the shell to prevent the equipment from shaking during operation.

[0006] As a further description of the above technical solution: The auxiliary mechanism includes a fixing ring, the inner wall of which is fixedly connected to the outer wall of the waterproof shell. Limiting posts are slidably connected to the left and right sides of the outer wall of the fixing ring. A limiting ring is threadedly connected to the outer wall of the limiting post. Positioning posts are slidably connected to the top left and right sides of the shell. Multiple support legs are fixedly connected to the lower middle part of the outer wall of the positioning post. A drill bit is fixedly connected to the bottom of the positioning post.

[0007] As a further description of the above technical solution: A handle is fixedly connected to the top left and right sides of the outer shell, and an anti-slip sleeve is fixedly connected to the outer wall of the handle.

[0008] As a further description of the above technical solution: A controller is fixedly connected to the center of the top surface of the housing, and the controller is electrically connected to motor one and motor two.

[0009] As a further description of the above technical solution: A display screen is fixedly connected to the top left side of the housing of the controller, and a knob is provided on the top right side of the controller.

[0010] As a further description of the above technical solution: The top of the outer wall of the positioning column is threaded with a limit ring 2, and a marking plate is fixedly connected to the front side of the outer shell.

[0011] As a further description of the above technical solution: A rotating shaft is fixedly connected to the rear right end of the outer casing, and a rear cover is rotatably connected to the outer wall of the rotating shaft.

[0012] As a further description of the above technical solution: A second handle is fixedly connected to the left rear side of the back cover, and a second anti-slip sleeve is fixedly connected to the outer wall of the second handle.

[0013] This utility model has the following beneficial effects: 1. In this utility model, after the equipment is fixed, the motor is started to make the elliptical disk rotate, which pushes the fixed plate to move up and down. The fixed plate is connected to the hollow tube. When the speed of the motor increases, the hollow tube and the drill bit 2 vibrate rapidly. The drill bit 2 is inserted into the ground. Then the motor is started, the spiral blade rotates, and the soil is transported upward through the spiral structure on the outer wall. This can realize the drilling of the geology and facilitate the sampling of soil, thereby improving the sampling efficiency and the accuracy of the test.

[0014] 2. In this utility model, the positioning post is first inserted into the ground, and the drill bit helps the positioning post to go deeper. After the positioning post is fixed, the support foot is also inserted into the ground to enhance stability. When disassembling the spiral blade, the limiting ring is rotated to disengage it from the limiting post, and then the limiting post and the spiral blade are pulled out. This realizes the disassembly and maintenance of the hollow tube, improves the stability of the equipment, and reduces the maintenance time of the equipment. Attached Figure Description

[0023] As an exemplary implementation of this embodiment: In use, after fixing the device in the designated position, start motor 3. Motor 3 will drive the elliptical disk 4 to rotate. During the rotation of the elliptical disk 4, it will push the fixing plate 7 to move up and down. Since the fixing plate 7 and the hollow tube 5 are fixedly connected, when the speed of motor 3 increases, the hollow tube 5 and the drill bit 6 will vibrate up and down rapidly, thereby inserting the drill bit 6 into the ground. At this time, start motor 9. Motor 9 will drive the spiral blade 10 to rotate. During the rotation of the spiral blade 10, it can transport the soil that has entered the hollow tube 5 upward through the spiral structure on the outer wall, thereby realizing the drilling of the geology and facilitating the sampling of soil, thereby improving the sampling efficiency and the accuracy of the detection. Before sampling, the positioning post 204 is inserted into the ground. The tip of the drill bit 206 makes it easier for the positioning post 204 to be inserted into the ground. When the positioning post 204 is inserted to a certain depth, the bottom end of the support leg 205 will also be inserted into the ground, thereby improving the stability of the positioning post 204. When the spiral blade 10 needs to be disassembled, the limiting ring 203 is rotated so that the limiting ring 203 rotates out from the outer wall of the limiting post 202. At this time, the limiting post 202 is pulled out, and the spiral blade 10 can be pulled out from the inside of the hollow tube 5, realizing the disassembly and maintenance of the hollow tube 5, improving the stability of the equipment, and reducing the maintenance time of the equipment.
