Description

Technical Field

[0001] The invention belongs to the technical field of geological survey sampling devices, and specifically refers to a geological survey device for geological engineering. Background Art

[0002] Geological survey is a survey and research activity that uses various means and methods to investigate and detect geology, determine the appropriate bearing layer, and determine the foundation type and calculate the foundation parameters based on the bearing capacity of the bearing layer. In the process of geological survey, it is necessary to use geological survey equipment to conduct large-scale sampling of rock structure.

[0003] In the prior art, when sampling a rock layer, water cooling is used for cooling, and the current state of the rock sample is destroyed, thereby affecting the data of the sample. When water cooling is not used, the sampling generates a lot of dust, which affects the user's use environment. After the sampling is completed, the sampling tube needs to be knocked to pour out the rock sample, which is inconvenient to operate.

[0004] Therefore, a geological surveyor for geological engineering is needed to solve the technical problems in the prior art that water cooling destroys rock samples during sampling, large sampling dust occurs when water cooling is not used, and the sampling tube needs to be knocked to pour out the rock samples. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a geological surveyor for geological engineering. When sampling, the sampling tube is cooled by high-pressure airflow, which not only cools the rock sample but also does not destroy its original state, thus solving the technical problem of water cooling destroying the current state of the rock sample in the prior art. At the same time, the high-pressure airflow can also be used as a power source for rotation during sampling to drive the sampling of the rock layer. By mechanical guidance, before sampling, the dust hood first drills into the rock layer to filter the dust generated by the sampling, and when sampling the rock layer, the dust hood no longer drills into the rock layer. After the sampling is completed, the dust hood is reset to the initial position to facilitate the completion of the next sampling work, thus solving the technical problem of large sampling dust when water cooling is not used. After the sampling is completed, the high-pressure airflow can smoothly discharge the sampled rock sample, thus solving the technical problem of needing to knock the sampling tube to pour out the rock sample in the prior art.

[0014] The beneficial effects achieved by the present invention using the above structure are as follows: 1. The present application utilizes high-pressure airflow to cool the inner sampling tube. During the rock sampling process, the original environmental state of the rock sample is kept intact while cooling. At the same time, the high-pressure airflow can also blow the rotating impeller to rotate, drive the inner sampling tube and the outer sampling tube to rotate, and sample the rock layer. While sampling, the outer sampling tube drives the spiral guide groove and the longitudinal guide groove to rotate by mechanical guidance, and drives the dust hood to rotate. The dust hood first drills into the rock layer, and then the inner sampling tube and the outer sampling tube follow up and drill into the rock layer. The dust in the drilled sample is filtered through the filter. After the sampling is completed, the inner sampling tube and the outer sampling tube return to the initial position. When the storage tube is moved to be coaxial with the inner sampling tube, the clamping block clamps and fixes the storage tube by mechanical guidance. The rock sample drilled in the inner sampling tube is blown into the storage tube by the high-pressure airflow, so as to realize the storage of the rock sample. 2. The high-pressure airflow enters the air inlet groove and spiral cooling groove on both sides of the inner sampling tube to cool the inner sampling tube. During the drilling process, the rock sample is not damaged and the failure to sample due to high temperature is avoided. The high-pressure airflow then passes through the return air groove and air guide groove on both sides of the outer sampling tube, passes through the air outlet ring and enters the rotating shell, blowing the rotating impeller to rotate. Through the meshing action of the gears, the inner sampling tube and the outer sampling tube are driven to rotate to sample the rock layer. After the sampling is completed, the high-pressure air blowing head blows out the high-pressure airflow to blow the drilled rock sample into the storage tube; 3. The rotating outer sampling tube drives the spiral guide groove and the longitudinal guide groove to rotate. The longitudinal guide groove drives the dust hood to rotate through the guide head and the fixed block, so that the dust hood drills into the rock layer first. As the inner sampling tube and the outer sampling tube gradually drill the rock layer, the guide head contacts the spiral guide groove. At this time, the dust hood stops entering the rock layer. At the same time, the extrusion spring presses the dust hood to filter the dust generated during the drilling process. While cooling with air, the dust is prevented from affecting the use environment. After the sampling is completed, the inner sampling tube and the outer sampling tube are reset, and the extrusion spring continues to press the dust hood. Under the guidance of the spiral guide groove and the longitudinal guide groove, the dust hood is reset to the initial state to prepare for the next sampling. 4. After the sampling is completed, the pneumatic telescopic rod moves the storage tube to be coaxial with the inner sampling tube through the driving plate, the fixed guide block squeezes the moving guide block, pushes the clamping block to fix the storage tube, and stretches the fixed spring at the same time. After the rock sample is stored, the pneumatic telescopic rod pushes the storage tube to return to its initial state through the driving plate, the fixed spring is reset, the storage tube is not fixed, and the storage tube is removed.
