Description

Technical Field

[0001] This utility model belongs to the field of data acquisition equipment technology, and in particular relates to a high-efficiency sampling device for geotechnical engineering exploration. Background Technology

[0002] From an engineering and construction perspective, "rock and soil" is a general term for any type of rock and soil that makes up the Earth's crust. Rock and soil can be further divided into five categories: hard (hard rock), medium-hard (soft rock), weakly bonded, loosely bonded, and those with special composition, structure, state, and properties. In China, the first two categories are conventionally called rocks, and the latter three are called soil, collectively referred to as "rock and soil." Sampling devices are needed to collect samples of rock and soil during exploration.

[0003] Existing equipment struggles to collect samples from hard soil, requiring drill bit replacements and significantly impacting efficiency. Furthermore, the large size of the equipment necessitates manual securing, which is inconvenient. During operation, the drill bit generates high temperatures from friction with the soil, necessitating manual water spraying for cooling. After use, the drill bit may be covered in sand and mud, and manual cleaning can result in scratches due to its sharpness. Therefore, we propose a high-efficiency sampling device for geotechnical engineering investigation. Utility Model Content

[0016] The beneficial effects of this utility model are:

[0017] 1. This high-efficiency sampling equipment for geotechnical engineering exploration operates by starting a third motor. The third motor drives a second gear to rotate, which meshes with the first gear, thus rotating the sampling tube. Then, starting the second motor again drives a first bevel gear to rotate, which meshes with the second bevel gear. Because the outer wall of the one-way threaded rod is threaded to one of the sliding sleeves, controlling the rotation direction of the one-way threaded rod adjusts the up-and-down movement of the sampling tube. When the sampling tube is excavating geotechnical soil, if it encounters a harder layer of soil or rock, the outer side of the sampling tube... The wall-mounted crushing drill bit assists the sampling tube in breaking up harder rock and soil layers to achieve the effect of sampling rock and soil samples. During mining, the sampling tube rotates at high speed against the ground, and the surface of the sampling tube will generate high temperature, which will affect the mining of rock and soil samples. At this time, the angle of the water inlet box is adjusted by extending and retracting the compressed cylinder. After the water inlet box is aligned with the position of the sampling tube, the nozzle on the water inlet box sprays water stored in the water tank to cool the sampling tube. This equipment not only improves work efficiency, but also achieves a fully automatic effect, without the need for manual adjustment by workers, which has practical benefits.

[0018] 2. This high-efficiency sampling equipment for geotechnical engineering investigation operates as follows: Before use, the worker holds the handle and pushes the equipment to the designated sampling point. The first motor is then activated, driving a bidirectional threaded rod to rotate. Two threaded sleeves move in the direction of the rotation of the bidirectional threaded rod. When the equipment needs to be secured, the two threaded sleeves move in opposite directions, causing multiple mounting posts to move downwards. Multiple insertion rods, due to the downward movement of the mounting posts, are deeply inserted into the ground until the overall position of the equipment is fixed. The equipment is then activated to collect geotechnical samples. After collection, the first motor is activated in the opposite direction, causing multiple insertion rods to rise and release the limiting fixation. Because the equipment is large, this structure eliminates the need for manual fixation, making it not only convenient but also more stable and practical than manual fixation.

Since the outer wall of the one-way threaded rod 29 is threadedly connected to one of the sliding sleeves 38, controlling the rotation direction of the one-way threaded rod 29 can adjust the up-and-down movement of the sampling tube 13. When the sampling tube 13 is mining rock and soil, if the sampling tube 13 touches a harder rock and soil layer, the crushing drill bit 46 installed on the outer wall of the sampling tube 13 will assist the sampling tube 13 in crushing the harder rock and soil layer, thereby achieving the sampling of rock and soil samples. In terms of efficiency, during mining, the high-speed rotation of the sampling tube 13 on the ground generates high temperatures on its surface, affecting the extraction of soil and rock samples. At this time, the angle of the water inlet box 43 is adjusted by extending and retracting the compressed cylinder 41. After the water inlet box 43 is aligned with the sampling tube 13, the nozzle on the water inlet box 43 sprays water stored in the water tank 14 to cool the sampling tube 13. This equipment not only improves work efficiency but also achieves a fully automatic effect, eliminating the need for manual adjustment by workers and providing practical benefits.
